The project is built-in Visual Studio . This was previously a dynamic link but it turns out that in IPP 7.1 dynamic libraries are internally multi-threaded which is disallowed for me so I changed it to a static link-to single-threaded IPP . The size of the lib then increased from several MB to about 150MB . Is this normal for such a link I am only calling one function from IPP as I said . In the latest IPP 8.2 multi-threading is deprecated https : software.intel.com en-us node 503931 so updating would solve the problem for me . However I am still intrigued by this . If I am only using a single function from the library wouldn t static linking be a more correct option And is such an inflation of the lib size to be expected .. . Answer : First need to clarify the your project model . Static library usually is not linked to any of external libraries . Static library is just an archive of object modules if we talk about Windows .lib files of course . You use linker only when producing application executible .exe file or dynamic library .dll . I can assume that your solution has two projects - one for static library and the default project for application . In this case linking to dynamic IPP library definitely minimizes application footprint because application does not contain IPP function code only calls to external function from dynamic library . The functions are stored in dynamic library files there are hundreds of MBs . If you want to build your application with static IPP libraries and at the same time decrease application executable size you need to limit the CPU optimization included into your application simultaneously . When you do nothing special just use static IPP libraries in the command-line to the linker the application object file is linked with all function variants optimized for different CPU architectures from SSE to AVX2 . For example if you included function ippSomeFunction into your source code the linker will add ippSomeFunction SSE + ippSomeFunction SSE2 + .. . + ippSomeFunction AVX2 to application executable . This will increase application size but will allow execute your application on any of Intel CPUs with most optimization for current CPU . The dispatcher will turn on the most appropriate function variants for CPU . If you know the target CPU architecture you can make linker to add only required optimization of the functions . Read readme.htm doc in your IPP installation directory ipp tools ia32 or intel64 staticlib . In this case the only change you need to do for the source code is to add include ipp cpuletter .h file before including of other IPP-related .h files e.g .", "Question : I m trying to write a program for an exercise that uses a static library - .a and .h files provided by the school .

The library is built on another much more extensive static library libopencm3 .. . .. . I just have one for now c file compiled to one object file that is then archived .

And try linking everything when I build my program lsm303.bin . But when I do it looks like libopencm3 is not linked to my static library . Any insight on this Should I be linking my library when I build it Comment : Static libraries are just simple archives of compiled objects and so when you build a static library there will be no linking process as making a shared library or an executable will do . Without linking the compiler will not check for symbol reference and so even though your static library make use of libopencm3 libopencm3 will not get packed into your library . And to make all short when you compile a program using your static library you should link-to both your library and libopencm3 . But of course you can unarchive libopencm3.a and pack it into your own library . Comment : Thanks TwilightSun for answering my question regarding linking the static library at build time .

Answer : The reason is historical . The ar tool was original the file archive tool on PDP11 unix though it was later replaced entirely by tar for that purpose . It stores files object-files in this case in a package . And there s a separate extension containing the symbol-table for the linker to use . It s possible if you are manually managing files in the archive that the symbol-table can get out of date . The short answer is that you can use the ranlib tool on any archive to recreate the symbol-table . Try that . More broadly try to figure out where the corrupt libraries are coming from and fix that . Comment : I think the OP means link against a library not create a library .", "Question : In my app i currently have all my code separated into a static library to make it easier to set up the xcode project targets for the actual app and for unit tests for my code . The problem with this is that i want to put most of my xib files in the static library as well but it seems that when i run my app and try to reference the xib it can t find it unless it is included in the actual app s target instead of the static library target . Is it possible to have xib files and other resources included in static-libraries that can be referenced by code in that same library and if so how .. . Answer : No it isn t possible because a static library is not the same as a bundle . A bundle is a directory that may contain all manner of files including resource files xib executable files and static-libraries . It exists on the filesystem as a group of individual files . A static library is a single file that contains classes code and variables that were linked together by the library creator . It does not contain other files it is essentially a database of compiled code . Although it would be possible to put the data for the xibs in there Xcode would have no way of knowing that it was in there as it looks for them as individual files on the filesystem .

The linker-error I see is likely caused by the inability for visual-studio to find the actual implementation of the method in the static library I have included in my solution . It is my understanding that the only .lib file I need to include is the one static library file . That is all I have included right now . Does anybody know why VS can t find the implementations of this code in the OpenCV static library Comment : When you used CMake did you specify if you wanted to build shared libs It should have generated way more libs than just ippicvmt . Also are you building a debug or release version Comment : I m currently trying to build for release and the project settings are all for release build . I did not touch the CMake settings so I m not sure . Should I have it build shared libs Comment : Remake the openCV solution and uncheck build shared libs . That will tell openCV to compile static libs rather than DLLs Comment : I see the other libs it generated in .. . opencv .. . lib my understanding is that these were only useful if I was going to use the .dll s Comment : That is incorrect . When building a program with static-libraries you need to link in more libraries . You can see this post for more info : stackoverflow.com questions 16830842 http : stackoverflow.com questions 16830842 using-static-libraries-instead-of-dynamic-libraries-in-opencv An easy fix would be to include all the non-debug libs ones that don t end in d . You can also include just the ones you need which I believe would be core300 and video300 . Building a program with static libs is a pain but once you get all of the libs you need linked then it isn t too bad . .. . Answer : I fixed my issue by disabling the flag for building with shared libs in CMake after that way more .lib files show up in the sharedlib folder in my install .

Answer : Have you cared to indicate to GCC the path of your library using -L By using -l solely GCC will only be able to link libraries available in standard directories . Comment : Yes the paths to each library are provided using -L before the corresponding -l flag . GCC can find the library but gives a large number of undefined-reference errors from within the library .", "Question : What is inside of a .lib file of Static library Statically linked dynamic library and dynamically linked dynamic library How come there is no need for a .lib file in dynamically linked dynamic library and also that in static linking the .lib file is nothing but a .obj file with all the methods . Is that correct Comment : It could be noted that the question is about MS Windows platform . .. . Answer : A lib files is read by the linker and a dll file is used during execution . A lib file is essentially useless during execution and a linker is incapable of reading a dll file except possibly in a manner irrelevant here . The differences between the use of lib files for static and dynamic linking might be confusing but if you understand a little history then it becomes very clear . Originally there were only static-libraries . For a static library the .lib file contains obj files . Each obj file is the output of one and only one compiler source code input file . A lib file is just a collection of related obj files much like putting obj files in a directory . That is essentially what a lib file is a library of obj files . For a static link all of the obj files that an executable uses are combined into one file . Compare that to a dynamic link in which the executable is in a file separate from the other code it uses . To implement dynamic linking Microsoft modified the use of lib files such that they refer to a dll file instead of locations in an obj file . Other than that all the information that is in a library for a static link is the same as for a dynamic link . They are all the same as far as the information in them except that a lib file for a dynamic link specifies the dll file .", "Question : Why is it that some static-libraries lib .a can be linked in the same way that shared-libraries lib .so are linked ld -l switch but some can not I had always been taught that all libraries static or not can be linked with -l.. . however I ve run into one library so far GLFW which does nothing but spew undefined-reference link errors if I attempt to link it this way .

Answer : Thanks for the replies Turns out the problem was due to link order . Apparently if you use a library which in turn has other library dependencies those other dependencies must be listed after the library not before as I had been doing . Learned something new", "Question : today i found out that the compiled static library i m working on is much larger in Release mode than in Debug . I found it very surprising since most of the time the exact opposite happens as far as i can tell . The size in debug mode is slightly over 3 MB its a fairly large project but in release it goes up to 6 5 MB . Can someone tell me what could be the reason for this I m using the usual Visual Studio 2008 settings for a static library-project changed almost nothing in the build configuration settings . In release i m using O2 and Favor size or speed is set to Neither . Could the O2 Maximize speed cause the final .lib to be so much larger than the debug version with all the debugging info in it EDIT : Additional info : .. . Debug : .. . - whole program optimization : No .. . - enable function level linking : No .. . .. . Release : .. . - whole program optimization : Enable link-time code generation .. . - enable function level linking : Yes Comment : What about whole program optimization and function-level linking settings in both configurations Comment : Updated the info . .. . Answer : The difference is specifically because of link-time code generation . Read the chapter Link-Time Code Generation in Compilers - What Every Programmer Should Know About Compiler Optimizations https : msdn.microsoft.com en-us magazine dn904673.aspx on MSDN - it basically says that with LTCG turned on the compiler produces much more data that is packed into the static library so that the linker can use that extra data for generating better machine code while actually linking the executable file . Since you have LTCG off in Debug configuration the produced library is noticeably smaller since it doesn t have that extra data .

I must use the -fPIC option because eventually this library will be linked with other static-libraries to form a dynamic library . When I test the static library locally it works completely fine when I don t include the -fPIC option . But as soon as I compile the library with -fPIC I receive a segmentation-fault error at run-time when calling one of the functions . What reasons could including -fPIC to compile a static library cause a segementation fault at run-time Comment : This is very generic I know but if your code contains Undefined Behaviour then anything may happen and changing a compiler flag may cause the compiler to exploit that UB in a new way - in any case the bug is in your code if UB is involved . Just a long-shot guess.. . Comment : That s along the lines I was thinking too . I did a fair bit of reading on -fPIC and couldn t find anyone else reporting run-time errors in their code by including it in most cases it was including -fPIC that was the solution to their problems Comment : Maybe you could provide a minimal reproducible compilable test case that we could try . That would help diagnosing the problem . See sscce.org http : sscce.org Comment : I agree I ll look into creating one . The problem is the static library is compiled from a very large codebase and is not something that can be made public . .. . Answer : A dynamic library is supposed to be loaded at run-time and can therefore not have position-dependent code . A static library on the other hand is just an archive of object-files . When linking with a dynamic library the linker adds the name of the library in the executable file so the loader can load it when it loads the program . When the linker links with a static library it basically extracts the object-files and links with them like any other object file . So unless you create an executable where all other object-files are position-independent you use -fPIC for your the programs code then you can t link with a static library which uses position-independent code the generated executable is simply not set up for it . Comment : So let s say I compile a static library with the -fPIC option . Now I want to compile that static library with Test.cpp which has a main method . When I run the generated executable only ONE of my functions callled by main causes a segmentation-fault while the rest of the code works fine . But when the static library is compiled WITHOUT -fPIC then all of the code in the generated executable works g . So why does the inclusion of -fPIC cause only some of the code to fail Comment : @ConnorFlood It s really impossible to say without more information and depends on what all your functions are doing .

I don t know what s best in theory but in practice I just spent a couple of weeks tweaking toggling and cajoling every build setting and config arrangement under the sun . In the end the only thing that works was remove ALL static-libraries both binary files AND dependent projects to build static-libraries from the static library that depended on my app . Don t link libraries to libraries . Don t be a hero . Just attach everything to your app directly . Save yourself heaps of time in the process .", "Question : At least on Linux and Solaris static-libraries are really just a bunch of compiled .o s tossed into one big file . When compiling a static library usually the -fpic flag is ommited so the generated code is position dependent . Now say my static library is B . I ve built it and have the resulting .a file which is really just a glob of all of the position dependent .o files . Now I have a shared library I d like to build A and I want it to statically link B . When I build A naturally I ll use the -fpic flag to make the generated code position independent . But if I link against B aren t I mixing position dependent and position independent object-files I m getting a lot of text relocation errors unless I also specify -mimpure-text and I think this maybe the cause . It seems when I compile a library I really need to compile it 3 times a shared version a static version and a static-that-can-be-used-by-shared-libs version . Am I right I could just keep using -mimpure-text but the g++ man page says that if you do that the object doesn t actually end up being shared it s unclear if it s all unshared or just the statically linked parts though does anyone know . Comment : Mixup - In your first paragraph you say -fpic makes code position dependent but in your second paragraph you say the same flag makes code position independent I suspect one of these is wrong . Comment : I don t think a .a file in Linux is a compressed file . AFAIK a .a archive is still the simple format from vintage Unix . Comment : The question is stated correctly he omits -fpic in the first paragraph leading to position-dependent code then uses it in the second paragraph leading to position-independent code . Comment : @lhf : you are correct fixed . .. . Answer : As an alternative approach ship two libraries : your shared one and the static you re linking against alongside .

You can t because you don t link with other libraries when you create a static library a static library is nothing more than an archive collecting object-files you don t actually use a linker to create a static library . The command ar and the filename suffix .a all stands for archive . If you have a static library that depends on another static library then you need to build with the other library as well for the final executable or dynamic library . Comment : To be fair you can .

Do I need static-libraries to statically link or the shared ones I have suffice If not why not Don t they contain the same data .. . Answer : Yes you need static-libraries to build a statically linked executable . Static libraries are bundles of compiled objects . When you statically link with to library it is effectively the same as taking the compilation results of that library unpacking them in your current project and using them as-if they were your own objects . Dynamic libraries are already linked . This means that some information like relocations have already been fixed up and thrown out . Additionally dynamic libraries must be compiled as position-independent code . This is not a restriction on static-libraries and results in a significant difference in performance on some common platforms like x86 . There exist tools like ELF Statifier http : statifier.sourceforge.net which attempt to bundle dynamically-linked libraries into a dynamically-linked executable but it is very difficult to generate a correctly-working result in all circumstances . Comment : Thanks for a great answer . But why is it so difficult Comment : ELF Statfier loads the executable and all its libraries then takes a snapshot of the process memory . When the output image is run anything which would cause the memory layout to change e.g . randomized VDSO will result in incorrect operation . Any other approach requires re-inventing the dynamic linker . Comment : Why would it be hard to reimplement the dynamic linker Isn t there just two tables of the library s imports and exports to be relocated It s the linker so it s already implementing a static linker and it knows the file-format of the executable and of the dynamic library etc . Comment : The operations of the static compile-time linker and the dynamic runtime linker are very different . The static linker rewrites references to symbols in objects to fixed references -- either to the relocated symbol within the same image or to a stub that jumps to the correct entry in the symbol-table . The dynamic linker opens files and maps them with specific rules to various parts of memory fills in the symbol tables and then jumps to initializing code .", "Question : I am using eclipse CDT in Ubuntu OS and have created a C project with external static library libtomcrypt linked to it .

Do i need to change the library included .. . Answer : In order to debug your code debugger will need some information eg which line of code corresponds to this object code in a executable . To make this information available you need to specifically instruct your compiler with -g option in gcc g++ . Suppose you have a library which you compile using makefile as in your case . You need to look in the makefile of library for flags used for compilation . As in .. . .. . And then you add -g option in flags : .. . .. . Incase your makefile doesn t use CFLAGS you need to look for lines where compilation takes place and add -g option to all those lines manually . Then make your library . Now you can compile you test programs like this : .. . .. . EDIT : Also note that -g option should be included during compilation and not during linking as you did . Comment : that solved the problem and just to know more about modes of -g option . My library makefile already has -g3 option maximum debugging included in CFLAGS but after including -g option only this thing got fixed and a library file with debugging options is generated . Is it any version compatibility issue or -g3 is not the appropriate option for debugging thanks for your help Comment : -g3 should be fine . I think the problem was that you included -g during linking except that it should be done during compilation . -g3 means extra debugging information also get stored which should work perfectly with all debuggers .", "Question : I want the users to be able to re-link my Qt-using application to their own build of Qt without being forced to rebuild all of the sources .

To make it easy using qmake I ve partitioned the project internally into : .. . .. . 1 . A static library-project that contains objects for all of the source files including the file that has int main int char . 2 . An application project that links the static library above with Qt .

I m doing the build under both MSVC 2008 Qt 4 and 2012 Qt 5 . The makefiles are generated by qmake . The problem is that the linking fails when building the application project . As soon as I add a dummy source file dummy.cpp to the application project the linking succeeds . Is there a way of avoiding this workaround .. . Answer : It turns out that the linker isn t clever enough to figure out what default runtime library is needed for the executable if only static-libraries are given to link with no discrete object-files . This can be corroborated by asking the linker to be verbose in the .pro file : .. . .. . When the dummy file is present in the application project the linker lists the following default libraries : .. . .. . Without the dummy file no default libraries are chosen by the linker at all .

So the most suitable answer is from Antonio P rez s reply http : stackoverflow.com questions 6869780 template-class-specialized-inside-and-outside-lib 6869869 6869869 . Comment : I believe your program is technically ill-formed and does not have to compile at all . Templates can and generally must violate the one-definition rule but the multiple definitions have to be identical . Your TImage violates that rule . .. . Answer : I am assuming here that you are building a static library because you do not have any decelspec dllexport or extern C in the code . What happens here is the following . The compiler create an instance of TImage char and TImage int for your lib . It also creates an instance for the your executable . When the linker joins the static library and the objects of the executable together duplicate code gets removed . Note here that static-libraries are linked in like object code so it does not make any difference if you create one big executable or multiple static-libraries and an executable . If you would build one executable the result would be dependent on the order the objects are linked in aka not defined . If you change the library to a DLL the behavior changes . Since you are calling over the boundary of a DLL each needs their copy of TImage char . In most cases DLLs behave more as you would expect a library to work . Static libraries are normally just a convenience so you need not put the code into your project . Note : This only applies on Windows . On POSIX systems .a files behave like .so file which creates quite some head aches for compiler developers . Edit : Just never ever pass the TImage class over a DLL boundary . That will ensure a crash . That is the same reason why Microsoft s std : : string implementation crashes when mixing debug and release builds .

After this your Android or client project will see any changes generated using Google- Generate Client Endpoint Library Comment : I am having the same problem . You seem to be bypassing the process . Does your app still work after you deploy it to the playstore I mean the idea is that your appengine code should be remote on a server somewhere and that the android code is supposed to be able to access it that way . Comment : I think by your-appengine-project you really mean your-android-project Comment : I do really mean your-appengine-project because that s where the library is that you are linking to . When the .apk file is made for Android it includes all the necessary parts of the libraries however you have linked to them in your source code . I ve been sharing folders like this with appengine connected android projects all the time . Have you tried this yet It works great for me . No moving code around every time I regenerate the endpoint library . Comment : I agree that sharing folders like that works well but I think there is a problem with your solution . You are generating the Android endpoint libraries into your app-engine project rather then the usual solution of generating them into an Android project . So what happens when you generate iOS or javascript libraries It appears to me that Google made the mistake of using the same paths for all .

This tutorial http : www.youtube.com watch v NU wNR UUn4 shows how the endpoints are getting generated automatically as well as the client library for Android . So we have our Entity : .. . .. . And the endpoint for this class : .. . .. . Besides using the generated Android Endpoint Library that uses the REST API I would like to add a User Interface on the Server build with Google Web Toolkit GWT . But how should I manipulate the date on Server Side I can see different approaches.. . .. . .. . Option A1 : Adding an RPC Service in GWT .. . .. . But now my PersonServiceImpl and PersonEndpoint do roughly the same . So we didn t follow DRY http : en.wikipedia.org wiki Don 27t repeat yourself : Besides that Person is not allowed to have com.google.appengine.api.datastore.Key so we would have to change our Entities . Option A2 : Service calls endpoint class .. . .. . Should work but still no com.google.appengine.api.datastore.Key Type in the Entity and since Endpoints are using CollectionResponse Person we would have to transform this into an Collection Person in case of listPerson . Option B1 : Using the Java Endpoint Client Library .. . .. . We could split the GWT Client from our App Engine API Backend and use the generated Endpoint Client Libraries for Java . So we call the REST Endpoint-API from within a RemoteServiceServlet . But wouldn t this end up in two Requests even if the GWT client and Endpoints are on the same server or even in the same project GWT Client -- RPC -- GWT Server -- HTTP Request -- App Engine Backend Server .. . .. . Option B2 : Using the JavaScript Endpoint Client Library .. . .. . Might be the best approach but would end up in massive JSNI . .. . .. . So what s best practice I can t find any example projects using Google Cloud Endpoints AND GWT in one project : Comment : Have you seen code.google.com p gwt-google-apis https : code.google.com p gwt-google-apis Comment : Yes but they are in an early Alpha Version and for the Google API . I m talking about your own API Endpoint generated by GAE . Comment : That library is for any discovery based API which your API Endpoint happens to be discovery based that is . Comment : I m having the same dilemma . We are looking to use the Endpoint API but develop a GWT front end . I have a feeling it may have to be one or the other.. . Comment : Also looking for solution . Using JSNI for now . .. . Answer : Maybe i don t understand something . But everything seems for me to be very easy . 1 . GWT client is not on the server . It is compiled Javascript executed in client s browser . 2 . Google plugin generates Javascript client code that calls Endpoint with suitable JSON . 3 . Above code can be called from GWT . Voila Comment : Yepp so this would be Option B2 . But as I mentioned it would work but ends up in a lot JSNI . Because the most part of the Client is written defined in Java GWT but the logic calling the endpoint is the generated Javascript code .

Is this really not doable It s been 8 hours without even one attempt at a reply . Comment : I think that GPE does not directly support this : your backend can not be configured to generate code to multiple Android projects so you will need to manually copy or sync the generated code between your Android projects . This seems like an oversight to me and I figure they will fix this eventually . .. . Answer : Try the below steps to ready your 2nd android app to use the same app engine backend with cloud endpoints : .. . .. . 1 Generate a client id for your 2nd android app in the api console .. . .. . 2 Update the existing app engine code generated from 1st app to include the id of the 2nd app in the list of allowed clients and deploy this code .. . .. . .. . .. . 3 Add the client libraries generated earlier from your app engine backend code to the 2nd app . Refer this link-to reconfirm the required libraries : Consuming endpoints in android https : developers.google.com appengine docs java endpoints consume android . You can also do a comparison between the libs folder of your 1st app and 2nd app to ensure all libraries are added . 4 In the 2nd app add the classes representing the models in your backend request initialisers etc same as in your first app . 5 In the 2nd app at required areas in your application logic you can access the api by creating the service object and then calling the api exposed by the endpoint", "Question : Google Plugin for Eclipse includes a facility to automatically generate the cloud endpoints client library . But there doesn t seem to be an easy way to move the generated source.jar file into your Android source . The documentation https : developers.google.com appengine docs java endpoints consume android says .. . .. . The Endpoints generation results in a sources jar file . Add the contents of this jar file to your Android project . It doesn t seem possible to put the source.jar file into an Android lib or libs since the source is .java rather than .class form . So I just manually copy over the source generated by GPE which they put in an endpoints-lib folder in your AppEngine project . This can be extremely cumbersome especially when you have more than one endpoint and are editing it often .

Does anyone know of a way to actually use the sources.jar file directly in the Android project Thanks . .. . Answer : The idea is that the wizard that generates the client library also copies it into your client project . But that depends on e.g . how you initially created your projects and even if it does work what if you have multiple clients projects or change your client project.. . so here are some ideas : .. . .. . I found a file that specifies which project the client libraries will get copied to in the .settings folder : com.google.gdt.eclipse.appengine.swarm.prefs : .. . .. . connectedProject target-android-project-name .. . eclipse.preferences.version 1 .. . .. . Manually changing this file worked for me but I haven t tried manually creating it if it doesn t exist . The other solution which you asked about is to manually copy the file . In my case I was able to copy the generated files from gae-project endpoint-libs to android-project endpoint-libs . If I remember correctly you must then find the sources jar file it is amongst the file you copied and will be easy to find and extract those into endpoint-name -v1-generated-source folder . You create this folder in the same folder where you found the jar . Clearly that is is not a great solution so. . .. . .. . There is an endpoints.cmd bat that can be used instead of the GPE Wizard - I suggest you look to see if it has a command for copying and extracting the generated library . I believe you would find it in the bin folder of the GAE J SDK . Comment : Thanks Tom . I think I have finally found a simple solution see my answer Comment : Creating it by hand and restarting Eclipse worked perfectly .", "Question : I have a problem with getting the userid for a cloud endpoint method .

The reason for this is that I want to secure my API or lock it down to only my specified clients . Sometimes I will have an app that does not have a user login . I would hate to pester my user to now sign in just so my API is secure . Or other times I just want to manage my own users like on a website and not use Google+ Facebook or whatever else login authentication . To start let me first show the way you can authenticate your Android app with your Cloud Endpoints API using the Google Accounts login as specified in the documentation https : cloud.google.com appengine docs java endpoints auth . After that I will show you my findings and a potential area for a solution which I need help with . 1 Specify the client IDs clientIds of apps authorized to make requests to your API backend and 2 add a User parameter to all exposed methods to be protected by authorization . 3 In Android call the API method in an Asynctask making sure to pass in the credential variable in the Builder : .. . .. . What is happening is that in your Android app you are showing the Google account picker first storing that Google account email in you shared preferences and then later setting it as part of the GoogleAccountCredential object more info on how to do that here https : cloud.google.com appengine docs java endpoints consume android . The Google App Engine server receives your request and checks it . If the Android Client is one of the ones you specified in the @Api notation then the server will inject the com.google.api.server.spi.auth.common.User object into your API method . It is now your responsibility to check if that User object is null or not inside your API method . If the User object is null you should throw an exception in your method to prevent it from running . If you do not do this check your API method will execute a no-no if you are trying to restrict access to it . You can get your ANDROID CLIENT ID by going to your Google Developers Console . There you provide the package name of your Android App and the SHA1 which generates for you an android client id for you to use in your @Api annotation or put it in a class Constants like specified above for usability . I have done some extensive testing with all of the above and here is what I found : .. . .. . If you specify a bogus or invalid Android clientId in your @Api annotation the User object will be null in your API method . If you are doing a check for if user null throw new UnauthorizedException User is Not Valid then your API method will not run . This is surprising because it appears there is some behind the scenes validation going on in Cloud Endpoints that check whether the Android ClientId is valid or not . If it is invalid it won t return the User object - even if the end user logged in to their Google account and the GoogleAccountCredential was valid . My question is does anyone know how I can check for that type of ClientId validation on my own in my Cloud Endpoints methods Could that information be passed around in an HttpHeader for example Another injected type in Cloud Endpoints is the javax.servlet.http.HttpServletRequest . You can get the request like this in your API method : .. . .. . But I am not sure if the necessary information is there or how to get it . Certainly somewhere there must be some data that tells us if the Client is an authorized and specified one in the @Api clientIds . This way you could lock-down your API to your Android app and potentially other clients without ever having to pester your end users to log in or just create your own simple username + password login . For all of this to work though you would have to pass in null in the third argument of your Builder like this : .. . .. . MyApi.Builder builder new MyApi.Builder AndroidHttp.newCompatibleTransport new AndroidJsonFactory null .. . .. . Then in your API method extract whether or not the call came from an authenticated client and either throw an exception or run whatever code you wanted to . I know this is possible because when using a GoogleAccountCredential in the Builder somehow Cloud Endpoints knows whether or not the call came from an authenticated client and then either injects its User object into the API method or not based on that . Could that information be in the header or body somehow If so how can I get it out to later check if it is there or not in my API method Note : I read the other posts on this topic . They offer ways to pass in your own authentication token - which is fine - but your .apk will still not be secure if someone decompiles it . I think if my hypothesis works you will be able to lock-down your Cloud Endpoints API to a client without any logins .

Unfortunately I haven t had any luck on this . I ve asked around my team and checked all of the documentation . It looks like using OAuth2 is your only option . The reason is because the endpoint servers handle the authentication before it reaches your app . This means you wouldn t be able to develop your own authentication flow and would get results much like what you were seeing with the tokens . .. . I would be happy to submit a feature request for you . If you could provide a little more information about why the OAuth2 flow doesn t work for your customers I can put the rest of the information together and submit it to the product manager . frowny face - however maybe it is still possible .. . Answer : I have implemented Endpoint Auth using a custom header Authorization and it works just fine . In my case this token is set after login but should work all the same with your app . Check your tests because the value should be there . The way to retrieve that header is indeed : .. . .. . String Auth req.getHeader Authorization .. . .. . You could take it a step further and define your own implementations of an Authenticator https : cloud.google.com appengine docs java endpoints javadoc com google-api server spi config Authenticator and apply it to your secure API calls . Comment : req.getHeader Authorization is null if you do not pass in a google credential from the Android client . I have also tried passing in my own implementation of an Authenticator but the problem still exists : if someone de-compiles your app they could spoof your app because your Authenticator is spelled out in black and white there.. . So I was hoping there was some way else.. . Comment : @micror thats not true . I have populated custom headers like auth with user defined values eg from an angular js client Comment : What part is not true Yes you can populate custom headers like auth by yourself but the fact remains : your app can be decompiled and spoofed . Please read my question again - the question shows how there is some sort of authentication Cloud Endpoints is doing to verify the Android client that they are not telling us about so maybe we can fish out the answer . Comment : there is some sort of authentication Cloud Endpoints is doing to verify the Android client that they are not telling us they send a bunch of headers set by Andoird in order to validate request origin there s no way to tap into that logic though .

How to add custom authentication to cloud endpoints where we previously check for a valid user session + CSRF token in our existing API .

Answer : From my understanding Google Cloud Endpoints provides a way to implement a RESTful API and to generate a mobile client library . Authentication in this case would be OAuth2 . OAuth2 provides different flows some of which support mobile clients . In the case of authentication using a principal and credentials username and password this doesn t seem like a good fit . I honestly think you would be better off by using OAuth2 . Implementing a custom OAuth2 flow to support your case is an approach that could work but is very error prone . I haven t worked with OAuth2 yet but maybe an API key can be created for a user so they can both use the front-end and the back-end through the use of mobile clients . Comment : OAuth2 always requires to have Google account which is the most troublesome problem to user .", "Question : I am an Android developer building my first Google App Engine java back-end for my apps . I don t want anybody else to access this API other than my app . I plan to use App engine for verifying InApp purchases in my Android app . My data is not relevant to users so I don t want users to be able to access my API even if they are logged in with their Google accounts on web or Android devices . I followed the steps mentioned in - Specifying authorized clients in the API backend https : developers.google.com appengine docs java endpoints auth like generating client IDs and add them in @Api clientIds and audiences except Add a User parameter - since I don t need user authentication . Then I deployed App engine and I am still able to access the API through API explorer https : your app id.appspot.com ah api explorer I haven t added API EXPLORER client ID .. . .. . I tested with the APK that was built with the endpoint libs before adding client IDs and can still access the API . Is adding a User parameter to all endpoint APIs a must to achieve my purpose restrict API to only my Android apps . Can I pass null as userAccount name from Android client and ignore user parameter value on server since it will be null Will this ensure that the API is accessible only from my android apps since the client ID is generated for my package name and SHA1 of the APK Should I use something like a service account for this purpose The documentation says for Android both Android and Web client IDs must be added and audience must be the same as web client ID . Does this open access to any other web client can I skip mentioning web client ID and still achieve my purpose Appreciate your time and help . ..... . updating with my further investigation .. . I did the following : .. . .. . Added User parameter to APIs on backend - but did not check for null value . API can still be accessed without passing any credentials from Android debug APK and API explorer .. . .. . Then I tried .. . .. . mCredential GoogleAccountCredential.usingAudience this server : client id : + WEB CLIENT ID mCredential.setSelectedAccountName null .. . .. . and passed this credential to API builder as suggested in some other posts Caused FATAL EXCEPTION . So we can t pass null account name . I could call the API using API explorer without OAuth . But when I enabled OAuth it gave error saying this client ID is not allowed I haven t yet added com.google.api.server.spi.Constant.API EXPLORER CLIENT ID in client ids .. . .. . Then I added code to throw OAuthRequestException on the backend if the user is null . This resulted in API explorer getting errors without OAuth . It works with OAuth enabled after adding API EXPLORER CLIENT ID to client ids .. . .. . Added code to pass valid user account name email from my Android app . Then I am able to access API only with my release APK . Even the debug APK gets exceptions - which is what I expected..So I assume no other Android apps will be able to access this API . So not checking for null user on back-end API is a bad idea as suggested in other posts . It is as good as not mentioning any client ids and not having User param . Only question I have at this moment is : If some one can figure out the WEB CLIENT ID from the APK will they be able to use it to build a web client to access my API I haven t mentioned client secret anywhere in the code .

Answer : I had a similar issue not between Android and App Engine but between a separate server and App Engine . The way I handled it was to add a signature hash field as a parameter to each API call . If the request had an improper signature it would be denied . For example suppose your API end-point is example.com api do thing param1 foo . I would hash the entire url along with a secret-key and then append the result-of the hash to the request : example.com api do thing param1 foo hash some long hex value . Then on the server-side I would first remove the hash from the url request then run the hash on everything that was remaining . Finally you check whether the calculated hash matches the one that was sent with the request and if they don t you can deny the request . It is very important however that your secret-key remain secret . You have to be careful with this on Android because someone could attempt to decompile your APK . Comment : Could you show some code what you used as your hash and secret Just want to get some more information on how this was done with cloud endpoints .", "Question : I have been doing extensive research on how to authenticate your client Android iOS web-app with Cloud Endpoints without requiring your user to use their Google account login the way the documentation https : cloud.google.com appengine docs java endpoints auth shows you . The reason for this is that I want to secure my API or lock it down to only my specified clients . Sometimes I will have an app that does not have a user login . I would hate to pester my user to now sign in just so my API is secure . Or other times I just want to manage my own users like on a website and not use Google+ Facebook or whatever else login authentication . To start let me first show the way you can authenticate your Android app with your Cloud Endpoints API using the Google Accounts login as specified in the documentation https : cloud.google.com appengine docs java endpoints auth . After that I will show you my findings and a potential area for a solution which I need help with . 1 Specify the client IDs clientIds of apps authorized to make requests to your API backend and 2 add a User parameter to all exposed methods to be protected by authorization . 3 In Android call the API method in an Asynctask making sure to pass in the credential variable in the Builder : .. . .. . What is happening is that in your Android app you are showing the Google account picker first storing that Google account email in you shared preferences and then later setting it as part of the GoogleAccountCredential object more info on how to do that here https : cloud.google.com appengine docs java endpoints consume android . The Google App Engine server receives your request and checks it . If the Android Client is one of the ones you specified in the @Api notation then the server will inject the com.google.api.server.spi.auth.common.User object into your API method . It is now your responsibility to check if that User object is null or not inside your API method . If the User object is null you should throw an exception in your method to prevent it from running . If you do not do this check your API method will execute a no-no if you are trying to restrict access to it . You can get your ANDROID CLIENT ID by going to your Google Developers Console . There you provide the package name of your Android App and the SHA1 which generates for you an android client id for you to use in your @Api annotation or put it in a class Constants like specified above for usability . I have done some extensive testing with all of the above and here is what I found : .. . .. . If you specify a bogus or invalid Android clientId in your @Api annotation the User object will be null in your API method . If you are doing a check for if user null throw new UnauthorizedException User is Not Valid then your API method will not run . This is surprising because it appears there is some behind the scenes validation going on in Cloud Endpoints that check whether the Android ClientId is valid or not . If it is invalid it won t return the User object - even if the end user logged in to their Google account and the GoogleAccountCredential was valid . My question is does anyone know how I can check for that type of ClientId validation on my own in my Cloud Endpoints methods Could that information be passed around in an HttpHeader for example Another injected type in Cloud Endpoints is the javax.servlet.http.HttpServletRequest . You can get the request like this in your API method : .. . .. . But I am not sure if the necessary information is there or how to get it . Certainly somewhere there must be some data that tells us if the Client is an authorized and specified one in the @Api clientIds . This way you could lock-down your API to your Android app and potentially other clients without ever having to pester your end users to log in or just create your own simple username + password login . For all of this to work though you would have to pass in null in the third argument of your Builder like this : .. . .. . MyApi.Builder builder new MyApi.Builder AndroidHttp.newCompatibleTransport new AndroidJsonFactory null .. . .. . Then in your API method extract whether or not the call came from an authenticated client and either throw an exception or run whatever code you wanted to . I know this is possible because when using a GoogleAccountCredential in the Builder somehow Cloud Endpoints knows whether or not the call came from an authenticated client and then either injects its User object into the API method or not based on that . Could that information be in the header or body somehow If so how can I get it out to later check if it is there or not in my API method Note : I read the other posts on this topic . They offer ways to pass in your own authentication token - which is fine - but your .apk will still not be secure if someone decompiles it . I think if my hypothesis works you will be able to lock-down your Cloud Endpoints API to a client without any logins .

Especially interested in Facebook . .. . Answer : You need to implement Facebook s client-side APIs according to their documentation and the environment you are deploying your client app to Browser vs iOS vs Android . This includes registering your app with them . Your registered app will direct the user to go through an authentication flow and at the end of it your client app will have access to a short-lived access token . Facebook has multiple types of access tokens but the one it sounds like you re interested in is called a User Access Token since it identifies an authorized user . Pass the access token to your Cloud Endpoints API via a field or header . Inside of your API code receive the access token and implement Facebook s API that checks the validity of the access token . The first answer on this SO question http : stackoverflow.com questions 5406859 facebook-access-token-server-side-validation-for-iphone-app makes it look rather easy but you probably want to reference their documentation again . If that check passes then you would run your API code otherwise throw an exception . You will typically also want to implement a caching mechanism to prevent calling the Facebook server-side validation API for each Cloud Endpoints request . Finally I mentioned that your client app has a short lived token . If you have a client app that is browser-based then you will probably want to upgrade that to a long lived token . Facebook has a flow for that as well which involves your API code requesting a long lived token with the short lived one . You would then need to transfer that long lived token back to the client app to use for future Cloud Endpoints API calls . If your client app is iOS or Android based then your tokens are managed by Facebook code and you simply request access tokens from the respective APIs when you need them .

Answer : No Scala Native currently doesn t provide JavaFX API . Comment : I know it is currently not possible to use the JavaFX library as is from a standard Java distribution . My question was about the library in its compiled form to native-code which already exists and has been used before with RoboVM ." ] }

Answer : With MVVM and WPF personally I would recommend starting without a framework . Once you see the sticking points the different frameworks will start to make a lot more sense . Remember the various frameworks for MVVM are meant to be helpers to ease some of the pain points when dealing with MVVM such as dialog service handling messaging etc .

Cinch doesn t destroy the Plugin class until it s told to disconnect .. . Answer : Use Unique Prefixes for Each Setting .. . .. . Because Cinch is threaded the easiest thing to do is make your key-value pairs idempotent . For example running setup could prompt the user to enter prefixed values each of which is handled as a separate event rather than chained together . Consider the following : .. . .. . While you could certainly chain your prompts by making each setting prompt for the next key-value pair you ll make life easier on yourself and your users by responding to setup with a list of asynchronous commands that can be handled in any order . You still have to ensure that each event writes to a collection in a thread-safe manner and that you serialize the collection at some point .

Comment : Did you start EventMachine EM.start I mean Comment : I do not know this library but it seems strange to me that you close the player before calling play . Maybe that s the problem Comment : @padde sorry copy mistake . I updated the question . What about EM.start", "Question : This has been giving me pain for some time . I know Prism injects views into regions however is there a way of doing a similar sort of thing with Cinch on a view first basis For example I have a container effectively a region which can contain any view at runtime - I don t particularly want to set the view explicitly in XAML as this will load it up and it s a bit messy . Is there a container that I can use for this And how would I go about it doesn t have to be Cinch specific. . .. . .. . thanks . .. . Answer : To answer my own question I ve found that Prism v4 has provided a useful solution - a RegionExtension called RequestNavigate . I have used RequestNavigate for opening a new window check out StockTrader RI however this seems extremely cumbersome if following the proper MVVM methodology . Instead I ve decided to use the ChildWindow class in the WPF Extended Toolkit where you can purely bind to the WindowState open closed property and specify everything else in XAML . I ve also used RequestNavigate for injecting views into Regions - I m now using MEF at the time I was using Unity . I find the approach a lot more flexible if slightly magic regarding debugging .", "Question : I am using cinch framework v1 .

The rails application will essentially function as a monitor for users and theoretically the data displayed will continually refresh . I have the basic IRC bot working on it s own and have written standalone rails applications before . I do not know what the best way to integrate them together is though Using sidekiq could start the bot but it does not give me a clean way to connect back into the website . Comment : sounds like you should build an api rest api maybe into your rails app . Comment : I don t want to have to send packets to the local webserver . That s extra delay that seems wasteful . .. . Answer : I see three options : .. . .. . 1 . Build an api and let your script send requests to that api endpoint .. . 2 . Use script runner to call your methods in your app directly .. . 3 . Let the script store data directly into the apps database .. . .. . I think the api solution is the only reasonable option for security and maintainablity reasons . Comment : Think performance will be good enough if I m using the api system Comment : The apis I have in use have average response times between 10-30ms . That depends a bit on what transformations or calculations you need to do before you can store the payload . How many requests to you expect per hour minute second Comment : We are integrating with twitch but doubt that our channels will be too popular . At most a hundred probably . Ideally the bot puts something in a queue that the rails app consumes .", "Question : I m developing an application with Sasha Barber s Cinch Framework for MVVM in WPF . This application shows two tabs . The MainWindowViewModel started a background worker that listens for incoming socket connections . If a client connects via the socket connection to the application the application should show up another tab . I setted up everything well but when I try to add the new Worskspace to the Views collection I receive an error that this can only be done in an dispatcher thread but there is no dispatcher in the MainWindowViewModel . So here s my question : How can I add this workspace to the views collection Greets and thanks Knutman .. . Answer : You could add a property with the following implementation to your VM base-class . Now you have a dispatcher in your VM . For more information please have a look here http : msdn.microsoft.com en-us library system.windows.application.aspx .

Answer : You created a 1 node-cluster with a relatively small machine type . By default Google Container Engine runs cluster add-ons logging monitoring that take up some of the resources in your cluster you can disable these if you wish . It looks like you don t have enough remaining space in your cluster to launch a pod that requires this many resources . Try disabling the cluster add ons when you create the cluster or provisioning larger or more nodes . Comment : Yes Robert . Without getting into details i upgraded to n1-highcpu-2 cluster and it solved my problem . But from eConomics perspective I need to know how much memory left in my cluster machine type g1-small which is having 1.7GB overall and only 4 Redis serv + client each about 100mb only allocated . So i am guessing when we ask for g1-machine type we have such limitation by google cloud by themself. . I don t see such limitation in the higher machine - type cluster n1-highcpu-2 . Can you please help me finding the remaining memory available for use Comment : To see the currently allocated resource usage on your cluster first run kubectl get pods --all-namespaces to see all of the running pods .

My metrics are not getting pushed to Stackdriver by default . Do I need to start Heapster service explicitly or is it automatically managed by container engine itself .. . Answer : If there isn t a Heapster pod running in your cluster then your cluster was created before we started enabling cluster monitoring by default . We are working on adding a way for users to retroactively turn on monitoring but if you want metrics pushed into stack driver today you will need to create a new cluster launching Heapster yourself isn t sufficient for the metrics to get collected .", "Question : Some of our containers run better with memory above the instance type currently deployed in our Container Engine cluster .

Answer : Container Engine doesn t currently have an API for doing this but since it uses a Compute Engine instance group https : cloud.google.com compute docs instance-groups for the nodes in your cluster you can actually update it without needing GKE s help . In the Developers Console copy the instance template https : cloud.google.com compute docs instance-templates that looks like gke-- and modify the machine type in it then edit the similarly named instance group to use the new template .

Answer : Currently there s only one way to get severity from your application into Cloud Logging without swapping out the default logging agent on the node which actually isn t that hard : configure your app to log structured JSON .

Actually Xenomai is quite proud of having the opposite feature- their threads maintain the high priority in user space . Therefore I am confused . Are there any real advantages too of maintaining the thread-priority in user space Comment : If those two assumptions don t apply . For example if the user space code acts as the kernel for other lower-priority user-space code or where the user-space code doesn t do much of the real work .

My question is is there a safe way to get gettimeofday s information from a Xenomai real-time thread I m considering adding my own version of gettimeofday to my Linux kernel my version would fail if read seqretry returns true unlike the regular version http : www.google.com codesearch gufiwQeQ0iA trunk kernels linux-2.6.16-gazineu kernel time.c q do gettimeofday type cs l 528 which will loop forever when that happens . However I d just as soon not start customizing the Linux kernel if there is a better way to do it . Comment : FWIW Gilles from the Xenomai-help mailing list says that Xenomai 2.6 will have a CLOCK HOSTRT clock feature that will satisfy this need . For earlier versions one work-around is to add an ioctl to a custom driver that returns the Linux real-time-clock without trying to loop if contention is detected .

POSIX skin . Clocks and timers services . Condition variables services . Interruptions management services . Message queues services . Mutex services . Semaphores services . Shared memory services . Signals services . Threads management services . Thread cancellation . Threads scheduling services . Thread creation attributes . Thread-specific data . I can t see anything regarding the file handling and socket programming so I am guessing that perhaps file handling and sockets are not to be dealt in the real-time Is the guess wrong Please guide . .. . Answer : Xenomai and its origin RTAI both take control of your scheduler handling the linux-kernel itself as a non-real-time thread . They have provided many services most of which as you can see is related to threads and synchornization that do NOT call Linux API in kernel space or system calls in user space . As you know real-time is all about guaranteeing deadline and calling Linux violates it because Linux doesn t guarantee anything . Since drivers are also important in real-time systems they have implemented the real-time driver model or RTDM that helps both implementing and using device drivers in a real-time context . File handling in kernel is strongly frowned upon . If you are talking about user-space real-time applications then you can have access to any drivers that is implemented in RTDM . If you don t find one for file handling or sockets then no you can t use them . Note that even a printf uses Linux system calls and is forbidden . Note that if you do use them nothing breaks you just lose your real-time-ness I personally do use files for logging but only call them in case of an error that means real-time is already ruined anyway . I don t know about Xenomai but at least in RTAI if you call a Linux system call then you get a warning like RTAI : LXRT changed mode : syscall .. . in your kernel logs . Comment : That s very helpful . Thanks . Can you point me to a link which talks about dos and don ts in real-time besides what Xenomai says Comment : @AnishaKaul let me search . Unfortunately there are not many real-time applications users for a wide range of information to be available on the internet . Comment : Yeah that is the problem . Please if you find something link up here . Thanks .

Answer : You could use mainline Linux kernel as TI now supports it : http : www.ti.com lsds ti tools-software mainlinelinux sw.page", "Question : What are differences pros and cons of the three referred real-time OS framework extensions or patches I want to measure a CPU timestamp counter TSC time in nanosecond everytime when a data frame or an ack frame of Wifi is sent or received . And I realized that one of three real-time technique is required to increase precision and reduce jitter due to preempt interrupt and context change . Currently I am applying RTAI to the kernel . As it takes a long time to compile I d like read something about those three . Could you recommend some documents or explain about it .. . Answer : Found an interesting paper comparing Xenomai vs Preempt-RT with a basic GPIO test vs stock kernel . https : www.osadl.org fileadmin dam rtlws 12 Brown.pdf .. . .. . Xenomai has better performance overall less jitter but using it will force you to redevelop custom driver using the specific RTDM api . On the other hand since Preempt RT is not in the mainline kernel it is less tested and you can also have issues . Xenomai3 has actually two approaches : either using a real-time micro kernel to manage real-time threads and interrupts or if you need less performance using it with a single preempt-rt kernel", "Question : I have Xenomai installed in an ARM PC Xenomai 2.5.6 - Linux Kernel 2.6.35.9 and I need to read a 10 kHz clock signal . The signal is electrically connected to one of my GPIO s which is mapped to a system file . If I create a task in user-space and open-read-close the file while measuring the time I get an average delay of 650 s i.e . this is the time that takes a full open-read-close cycle . This yields to a sampling rate of 1.5 kHz . Output : .. . .. . I ve read somewhere in the Internet that forcing my task to run in Kernel-space rather than user-space would enable it for a faster execution but I m not sure if this would be enough nor if what I m trying to do here is completely right . I come from an electronics engineering background where I have always been told not to treat synchronous signals like clock signals asynchronously and reading a file i.e . my sync . signal using a periodic task that may introduce jitter depending on the CPU system load doesn t look like a good approach . Is there a better way to do so Thanks .. . Answer : Here are my thoughts on a possible solution . You are right you shouldn t handle synchronous signals asynchronously . Therefore you should avoid opening a fd in userspace to read the signal level from the GPIO . Instead you should handle this in the kernel space where it s more appropriate . Once in the kernel space you can setup the GPIO as an irq to trigger on rising falling edge and handle it in real-time through Xenomai . The latency won t disappear but it should be OK for 10 KHz clock speed . Unfortunately you didn t specify what you are doing with the clock signal . I m guessing you are trying to act as a slave drive to some device Any way I hope I ve been helpful .", "Question : I m trying to cross compile C code for an embedded application that is running Xenomai 2.5.6 Linux 2.6.35.9 . I started with Xenomai examples and tried to compile them using their Makefiles but they are not working properly besides I want to cross-compile for my ARM machine . I ve followed this http : www.cs.ru.nl lab xenomai exercises ex01 Exercise-1.html tutorial and found a way to manually compile the sources that happens to be this one : .. . .. . Where arm-linux-gnueabi-gcc is the toolchain I m using to cross-compile for ARM -I home .. . is the path where the headers are and -L home .. . is the path where all libraries are located .

CFLAGS and LDFLAGS were generated using xeno-config as stated in the tutorial but when I execute the command I get the following linker-error : .. . .. . All rt .. . references are Xenomai s Kernel functions that are included in the libraries . .. . .. . EDIT : Adding -lrt to the command-line and ordering the arguments correctly i.e . -L at the end of the command-line does not solve the problem . In order to assure that the library does contain the functions I executed objdump and got the following result : .. . .. . Other things I did that may help finding the problem : .. . .. . 1 .

Removed a different toolchain . Since I was first using the ngstr m distribution in my target device I had a specialized toolchain for it . Now I moved to Debian and I am using the arm-linux-gnueabi toolchain provided in the binutils-arm-linux-gnueabi package http : packages.ubuntu.com quantal binutils-arm-linux-gnueabi . 3 . Compiled a new Linux Kernel and Xenomai for my target device . Kernel version is 2.6.35.9 and Xenomai s is 2.5.6 . Should I use an earlier version Anyway Xenomai is installed correctly since I can run the pre-compiled programs that were ironically compiled during Xenomai s installation by myself.. . Comment : Thanks @artlessnoise but I tried both adding -lrt and moving -L and -I to the end of the command-line and I still got the same error . Just as trial error method I tried writing wrong library names for instance -ltnativeee and the linker has outputted a different error cannot find -lnativeee which makes me think there is something wrong with the libraries themselves.. . What do you think Comment : Hmm . Your code is not C++ correct Can you run file librtdk.a in the .. . xenomai lib directory to double check you have an ARM xenomai there Also getting arm-linux-gnueabi-objdump -x librtdk.a grep rt print output to confirm a function is in the library Comment : Executing file librtdk.a I get librtdk.a : current ar archive while if I execute file librtdk.so.0.0.0 the output ends up being the expected librtdk.so.0.0.0 : ELF 32-bit LSB shared object ARM version 1 SYSV dynamically linked .. . . Executing the last command I get around 15 lines containing the keyword so I guess the function rt printf is present . Comment : Sure I ve added it to the question because it was too long for a comment entry . I m as stumped as you @artlessnoise.. . .. . Answer : It appears that magic has happened here . After two days messing around with Makefiles Xenomai CFLAGS and linker configuration I ve come to a point in which both the compilation and linking works with no problem . I really haven t done anything special . I haven t un installed any package other than the ones I already had nor modified any environment variable nor added any different flag or argument to my command-line . I just rebooted my computer . I didn t even do that on purpose I just left the lab yesterday with the command not working altogether and this morning everything works a treat . Strange Yes . I guess it is somehow related with exported variables in the terminal session . I remember I tinkered with LD LIBRARY PATH CFLAGS LDFLAGS and so on so I must have screwed something while trying to solve the problem . For those of you who are curious to know the final working command for cross-compiling Xenomai 2.5.6 applications for an ARM machine running Linux 2.6.39.5 this is it : Comment : Both -l and -L order is important .

Answer : There is a small chapter about it in Automation and Monitoring with Hubot https : leanpub.com automation-and-monitoring-with-hubot book shameless plug . Excerpt : .. . .. . Assigning Roles .. . .. . Only Admin users can assign roles . You don t have to create a role before assigning . All you have to do is tell Hubot who is who using hubot user has role role .

To remove the role from somebody use hubot user does not have role role : .. . .. . You can assign multiple roles to multiple users . Applying Roles .. . .. . Now time to break the bad news . While Hubot Auth is pretty flexible you will have to edit your scripts to apply those roles . Luckily there is not much to edit . There is a simple function that checks if user has a role - robot.Auth.hasRole msg.envelope.user role . This is how you use it in a script :", "Question : I have a pretty standard express app built using the express-generator . Now I would like to automate some of the things in the app with hubot and I have managed to successfully perform testing and run hubot with slack adapter . However I would like to have the bot be a part of a regular app . How can I change the structure of the app I have a pretty standard import of routes.js which has all of the routes for the app to allow for the two to run together This is running on azure as a WebApp and I have set up a continuous-integration with GitHub so I pretty much just push code and it gets deployed I don t run anything manually on the actual server . I would be able to run the hubot and server it on a different subdomain or path on the app if it was a regular VPS but since the azure is taking care of those things I would need the hubot somehow baked-in the actual express app . .. . Answer : As I know Hubot has a build-in express web framework that can serve HTTP requests . So theoretically you can integrate hubot with your express webapp thru the router dispatch different urls between express app and hubot . As references there is a experimental package project hubot-express shows that hubot as a express app-startup . you can try to refer to the code https : github.com hubot-scripts hubot-express blob master src hubot-express.coffee to implement the integration . The key code : robot.express app express .. . .. .

Are you over 13+ .. . .. . a . if yes go to 2 .. . .. . b . if no end .. . .. . 2 . Please pick a chat room .. . .. . Looking at hubot it looks like it looks for specific questions but doesn t necessarily store state or allow the progression of a longer interview by remembering previous answers and doing if this then that . Does hubot support this If not is there another open-source alternative that is a better fit for the use-case Would I just store user information in the hubot brain for each user s answer building up a user s state over time I suppose with each user answer we can look up the user s state and their current progression in the hubot brain and then handle it accordingly . However if it s more of a script rather than looking for any old random question via regex matching does this take away from most of the benefit of using hubot in the first place .. . Answer : This sounds like perfect use-case for Hubot . It s basically a node chat bot with a large number of pre-built integrations . It s meant to be extensible so adding custom things like this works fine as long as you re comfortable with the service running in Node . For simplicity I recommend persisting the Hubot brain and not talking to a different db backend if you don t have to . There are several options for automatically persisting hubot s brain hubot-redis-brain 1 is often used . 1 : https : github.com hubot-scripts hubot-redis-brain", "Question : I installed hubot heroku and hipchat . I deployed Hubot to Heroku and I tested on hipchat I typed some command-line example : @hubot help @hubot image me hubot ... . and It worked fine . But in my project I need use hipchat to deploy my project to heroku . Example when I type on hipchat is : @hubot deploy app then my project will be deployed to heroku instead of tying : git-push heroku master on Terminal . Please help me I really thank you so much .. . Answer : This is a very broad questions . There is no single answer . For sure you need a deployment service that performs the deployment . Hubot should ping the deployment service when you send the deploy command . The deployment service should have access to your repository and Heroku account and perform the git-push command for the deploy . The deployment service may have a local clone of your project or download it from some centralized location E.g . GitHub and perform a push to Heroku . The deployment service can be a server you control a third party service such as this one http : dploy.io the server where Hubot is running not ideal . Heroku also offers Dropbox sync https : devcenter.heroku.com articles dropbox-sync and is experimenting deploy from GitHub . In this case the deploy doesn t require a deployment service or to be more correct the deployment service is in fact Heroku . Hubot would simply trigger a new synchronization at Heroku as long as Heroku is connected to either GitHub or Dropbox depending on where the app is stored .", "Question : I am installing hubot on Linux and followed the instructions https : github.com github hubot wiki Deploying-Hubot-onto-UNIX receiving no errors .

Answer : Looks like your instance of Hubot is persisting the Hubot brain data store in Redis .

Every example I can find is including the HUBOT SLACK TOKEN in the call to hubot but it doesn t work for me I must be missing something . To rule out something locally I deployed the application to Heroku but I got a different error . package.json : .. . .. . external-scripts.json .. . Answer : What intrigues me is this particular line : .. . .. . Did you add the other scripts from the repo aswell There also might be something wrong with the node npm coffee installation version on your windows machine . Make sure that those are installed and in a compatible version . Another thread http : stackoverflow.com a 33858433 1309035 had an issue with incompatible versions . Please tell us about the versions you use and try downgrading node to 0.12.x . The way you use the token is fine .

Comment : Guzzle came up with the idea to rename the namespace they were using when going from version 3 using Guzzle to 4 using GuzzleHttp . They say they did it to allow using both versions concurrently which is technically correct but in the end it behaves like a completely different product now . Comment : And I am -1 this because NEVER EVER suggest installing branches like dev-master if you can by all means avoid it . Guzzle is an excellent example of a software using semantic-versioning - there is absolutely no reason to not install a numbered version like 4.0 .

Shall I create a component and write one function for each of Guzzle public function So I will have something like this this- HttpClient- post . 4 . Thing is I don t like any of the above and I was hopping maybe there could be another way to do this . For example create a components which loads the Guzzle Client in a controller or loads the Guzzle Client inside the component collection . .. . Answer : Do you really need Guzzle I agree that the old Cake2 HTTP socket is old fashioned but is there something it can t do that requires you to add yet another lib Use a trait as long as you re not stuck to an ancient php version this is a clean solution . Here is some pseudo-code that will give you the high level idea : .. . .. . If you ever need to change the config or the whole socket implement ion you just have to change it in a single place without the overhead of a component . Also this can be use in any class not just controllers . What you re looking for is more or less a simple factory like method no need for a whole controller . If you can t use a trait then you ll have to use a component or just put the above code not inside a trait nor a component but directly inside your AppController but you won t be able to use it outside the scope of the controllers that inherit that controller then . Comment : Isn t there any way to register the Guzzle Client as a component Comment : If you re so obsessed by using it as a component just apply the same code to a component or create a proxy to guzzle inside the component through the magic call method .", "Question : I m trying to connect to the WooCommerce API using Guzzle 5 Guzzle 6 seems not has oAuth options o.O .

Using curl direct from the command-line using the -d option or from PHP using CURLOPT POSTFIELDS does work . I start with a PSR-7 request : .. . .. . I add authentication header which authenticates against the API correctly : .. . .. . Then I add the request body : .. . .. . I can send the message to the API : .. . .. .

This should work and does work with curl from the command-line -d access token 123456789 but the API fails to see that parameter also when sending cia curl 6.x as above . I can see the message does contain the body : .. . .. . So what could be going wrong here Are the parameters not being sent or are they being sent in the wrong format maybe is being encoded or is perhaps the wrong content-type being used It is difficult to see what is being sent on the wire when using Guzzle since the HTTP message is formatted and sent many layer deep .

Edit : the command-line curl that does work sent to the same test script gives me two additional header fields in the request : .. . .. . I m going to guess it is the content-type header which is missing from the Guzzle request which is the source of the problem .

Answer : The GuzzleHttp Client provides all necessary wrapping . Documentation available Guzzle Request Options http : guzzle.readthedocs.org en latest request-options.html form-params .. . .. . Edit : However if your requests are being used within GuzzleHttp Pool then you can simply everything into the following : Comment : So the Guzzle client will put the correct Content-Type headers in provided you give it the raw data in the right way form params is the trigger here I guess . Guzzle will not add any headers without being given them explicitly when constructing a PSR-7 request message . My aim here was to construct a PSR-7 message that could be sent through any HTTP client supporting PSR-7 messages as much for the purity of just seeing that it can be done in as portable a way as possible so using only PSR-7 methods on the helper Guzzle PSR-7 package . Comment : There should probably be a space after Bearer within the quotes .

Just for the record I have listed the steps to get this working with Swift : .. . .. . 1 Import the files from the folder ACEAutocompleteBar to your project . 2 Create a bridging header and write import ACEAutocompleteBar.h at the top . 3 Make your view containing the text field an ACEAutocompleteDataSource and ACEAutocompleteDelegate . 4 Implement the minimumCharactersToTrigger function .. . .. . 5 Implement the inputView function . 6 Implement the textField function . 7 Call setAutocompleteWithDataSource on the textField . Hope that helps anyone looking for this kind of functionality Comment : Thanks It looks like an interesting library . I ll give it a go .", "Question : null .. . Answer : I have a UITableViewController with custom cells that have text fields in them . I want the table view to scroll whenever the user enters a text field so I do this : .. . .. . This method normally works great but when quicktype keyboard appears the quicktype bar partially overlaps the cell . How do I fix that overlapping issue Comment : If you do not need quick type keyboard then you can use textField.autocorrectionType UITextAutocorrectionTypeNo . If you need it why don t you scroll to row next to targeted one . Comment : I kind of don t want to get rid of the quick type keyboard unless there s just no other way . I was hoping there are cleaner solutions than just scrolling to the cell below . Also what happens when you want to edit the last cell", "Question : null .. . Answer : We have a text-entry view implemented using the UITextInput UIKeyInput and UITextInputTraits protocols . Basic text entry and deletion work fine via insertText : and deleteBackward . However QuickType suggestions are not received by these methods and I m unable to find documentation on how QuickType interacts with these protocols . How should I implement these protocols to receive QuickType input", "Question : null .. . Answer : I have a simple question to ask : can we append words to the iPhone s QuickType from Javascript I get auto-completion from field at now but it s ugly and I m asking why cannot use the built-in system keyboard auto-completion system . The main goal right here is to prevent auto-completion with div by using some more phone ability functionality .", "Question : I m developing a messaging app and would like the predictive keyboard in iOS 8 to recognize that the user who is composing a message is replying to the previous message . So I want to be able to feed a string to the keyboard to provide it context for prediction .

Is this available to developers Note that I m not talking about a custom-keyboard just feeding the standard keyboard some context for it s predictions . I m also not concerned with actually customizing the quick type replies as in this question http : stackoverflow.com questions 28315325 customise-the-quicktype-suggestions-in-ios-keyboard . I just want the keyboard to know what it s typing about . .. . Answer : As there s now way to find any further information on how to do this on the Official Apple Documentation I guess it s impossible . However you have two options : .. . .. . Keep the standard keyboard and manually display a bar within a UIView instance on top of it . Create your custom-keyboard from scratch much more difficult . You can read more here https : developer.apple.com library prerelease ios documentation UIKit Reference UIInputViewController Class . You can also think about a totally different UX . For eg . if your user is likely to choose one of your suggestions then only present these suggestions and keep a little button to enter a custom input and dismiss the keyboard here . If the user is likely to enter a custom input refer to both above alternatives . Comment : What a nice answer . Comment : This is a great succinct answer albeit not the one I wanted to hear arghh so thank you . I didn t create the bounty but feel obliged to choose the other answer as the most right . I think that a totally different UX doesn t work for me in this case as I am consciously trying to make an input that could easily be 2 buttons more of an NLP conversational input . Comment : No problem hope you will be able to do what you need the other answer", "Question : I m developing a messaging app and would like the predictive keyboard in iOS 8 to recognize that the user who is composing a message is replying to the previous message .

I just want the keyboard to know what it s typing about . .. . Answer : Strictly inputting suggestions to the default keyboard is not possible . However if you want to give the equivalent experience for the user I would hide the iOS suggestion bar using myTextView.autocorrectionType UITextAutocorrectionTypeNo and then replace that view with my own custom view that mimics the suggestion view until . Once the user types a character or selects an option then hide the custom suggestion view and re-enable the iOS suggestion bar . I Subclassed UIInputView just for this the transparency and the transition is a little off but everything else works pretty well . To implement this into a UITextField or UITextView that you ve already subclassed import the SuggestionView and implement the SuggestionViewDelegate . Then in the UITextFieldDelegate or UITextViewDelegate methods add : .. . .. . Then implement the SuggestionViewDelegate : .. . .. . While this isn t a perfect solution it does create the desired effect . Comment : While I was hoping someone would swoop in and say Yes it s possible just do XYZ this is an incredible answer . Thanks for sharing your code and approach - I just wish Apple would open this up though I suppose that s a small carrot to use Messages instead of WhatsApp FB Messenger Kik etc etc" ] }

Answer : I suspect the GreenSock platform is using Flash s own fl.motion.AdjustColor http : help.adobe.com en US FlashPlatform reference actionscript-3 fl motion AdjustColor.html which doesn t perform a particularly great transformation between RGB and HSV as you ve discovered . You have to take into account the perceptual brightness of different colours in order for it to look right so it s somewhat subjective .

You can use that to generate a matrix for a flash.filters.ColorMatrixFilter http : help.adobe.com en US FlashPlatform reference actionscript-3 flash filters ColorMatrixFilter.html then you ll probably have to write a function which takes the current tween time and run it onUpdate to use that with TweenMax . Comment : Thanks I read up on how colors are perceived with different intensities . It turns out that with the built-in Flash and Greensock hue code there is simply no way to generate certain colors depending on what color you start with . i.e . Purple will never become yellow .

I will be starting with either a RGBYTP red green blue yellow teal or purple color then through hue adjustments I will be able to make it look like each one of the other RGBYTP colored images .

A common technique in web game design . eyeballs http : quadradius.com stuff RandomImagesForLinking hue-adjusted-eyeballs.jpg .. . .. . I often use GreenSock Animation Platform TweenLite TweenMax but both core AS code and the TweenLite engine don t seem to handle hue as I expect . I want to adjust the hue color wheel by an increment of 60 degrees which should adjust through all 6 secondary colors nicely and get a full bodied color result from it .

In fact adjusting the hue of an RGBYTP color returns very weird results earth tones pastels even shades of gray . bad-hues http : quadradius.com stuff RandomImagesForLinking 6-colors-all-hue-adjusted.jpg .. . .. . Here is the code I use to generate all those circles with . Why do AS3 or TweenLite Max not handle hues like Photoshop or an artists color wheel What am I doing wrong Comment : Flash only supports RGB and ARGB colour formats . You ll need to cycle thru hues and convert each one to RGB format before applying it - googling should provide some algorithms for converting Comment : I m already using what many consider to be a great package of algorithms the GreenSock platform .

The results of the algorithm are in the image with the circles I included . For example if you start with purple you can never produce yellow . .. . Answer : Two colors don t go straight to black on the Real Color Wheel . Yellow goes to brown first and cyan goes to blue first . The brown is reds darkest color before black . Cyan goes to blues darkest color before black . I don t know any java but I sure would like a java wheel like this one . http : acko.net blog farbtastic-jquery-color-picker-plug-in .. . .. . The yellow eye is using the RGB gradation to dark and that s why it looks greenish the same for the cyan colored eye .

Don RCW Comment : Nice color wheel and it looks like you know your color rules But not sure if that answers it . The top image made in photoshop is just an example of what I want . When using the built-in Hue function in the Tweenlite package I don t get those results at all circles image . For example if I start with red the hue function produces a brown Purple will never get you anything close to yellow One of blue s go to near black It s like the hue algorithm is more suited to pick another pretty color rather than a hue adjusted output .

Just reload the page hover the object and you will see the error I am receiving . Thanks for your time .. . Answer : The main problem is not in the javascript but in the CSS . The .social-circle class does not have a fill which means it is actually 000 . This solves the initial animation http : codepen.io foozle pen zrpBmL you may or may not have noticed that the fill -animation uses a somewhat bright-colored transition from nothing to the purple . This seems to be because TweenLite interprets fill : none as fill : rgba 255 255 255 0 the latter being transparent white which in itself is not visible but the steps in the transition are . This is why I opted for the transparent version of your color in the code above . Now that your question is answered I feel like I should take some time to help you reducing the overall complexity of your solution .

Is there a way to also incorporate the ConvolutionFilter in that TweenLite call above I ve searched quite a bit and found some guy made a class called TweenMan which was based around your class where ConvolutionFilter is incorporated : https : github.com danro tweenman-as3 .. . Answer : Nothing to do with TweenMax here since your code is the one making the mistake . This correctly removes all current filter and apply only one : .. . .. . Since filters property is either null or is an Array . To add a filter to the list you use array operation and reapply the array : .. . .. . EDIT : starting over since I think I understand what you are trying to do . You are avoiding creating the filter yourself and let TwennLite do it for you even tough you don t need to tween anything . Don t do that you are making everything harder for yourself . Instead create your filter that way : .. . .. . If you need to animate multiple filters remember that most tween engine can tween easily array values so you can just do that and then apply those array values to your filters . Comment : I ve tried that and it isn t working . I d rather not use TweenLite but the syntax for applying filters makes it so easy . I ve also tried doing bitmap.filters bitmaps.filters conv Comment : The tween is running at the same time and messing up the whole filters property . Not sure if TweenLite supports running 2 filters at the same time but either way you can easily do it yourself . I ll show you how if you need to . Comment : why is the tween time set to 0 Comment : I tried adding a timeout of 1 second to apply the convolution filter and no luck . I am simply using TweenLite because of its easy syntax of applying brightness saturation and contrast . I am looking into how to apply those effects without tweenlite because I think I could solve the problem that way . The 0 second tween time is because I don t need it to actually tween . Comment : then apply it directly in the filters property directly .", "Question : Using GSAP I want to create one TweenLite or TweenMax object which acts different animations intended to play in parallel on multiple different objects . How can this be done I have only seen allTo which applies same animation on an array of multiple objects . It is important to get one tween as I need to pass it to ScrollMagic . I figured I can use TimelineLite or TimelineMax to do this too since that s OK with ScrollMagic . However is it possible purely using TweenLite or TweenMax Or the timeline is the only way to go Comment : If you intend to do different animations on multiple elements then yes TimelineMax is the best option . And I believe ScrollMagic can take TimelineMax and treat it as one single tween based on the assumption that you are going to be using its setTween method . .. . Answer : If you were to just use TweenMax and not TimelineMax . . then you could just use method-chaining and chain your tweens using TweenMax .. . .. . Using TimelineMax would be give you greater control . You could also chain with the TimelineMax constructor : .. . .. . Or just do like you were doing but with chaining : .. . .. . See TweenMax docs for more information : http : greensock.com docs HTML5 GSAP TweenMax Comment : Although you can chain TweenMax or Lite the .to method in TweenMax is a static method https : greensock.com docs HTML5 GSAP TweenMax to . Hence the tweens variable will just have the last call s tween object the other animations will play but won t be controllable . There is no true chaining happening and the code is misleading . In TimelineMax or Lite the .to method is non-static https : greensock.com docs HTML5 GSAP TimelineMax to so you are in fact doing a true chaining . Comment : Also I don t see the point in your last code block . If I already assigned it to var timeline why re-assign it to another var tl What advantage does it provide I can just use timeline variable in subsequent code . Comment : its just another way to assign your timeline to a variable. . you can see that in practice here when i assign many timelines to multiple elements . Storing my timeline in a variable and then assign that variable to another var associated with each DOM element . . see this example codepen.io jonathan pen KdYqWo http : codepen.io jonathan pen KdYqWo Comment : I changed line 22 to el.animation tl and removed the assignment var t tl replaced it with just tl . The page still works the same . Both var tl and var t are actually pointing to the same TimelineMax object . It doesn t seem to offer any advantage to assign the same object to two different variables . see : codepen.io anon pen MKyWbG http : codepen.io anon pen MKyWbG PS : TweenMax chaining in your answer is misleading . You should make a note of it and strike it out . Comment : Sorry about that codepen sometimes parses javascript wrong due to their infinite-loop check which can cause it to be buggy .

Answer : I think what you are looking for is called force3D http : greensock.com docs HTML5 GSAP Plugins CSSPlugin . Navigate to this link I shared and look for section named force3D on this page . Currently force3D defaults to a value of auto which means it will automatically decide when to use transform3d and when not to . Also there is a way to set it globally instead of appending it into every tween : .. . .. . Hope this helps . Comment : Hi I don t have such option . And if I inspect CSSPlugin I have only : defaultSkewType defaultSmoothOrigin defaultTransformPerspective . Comment : can you try adding force3D : false into your tweens first .

I ran into this neat issue of which when a user s data connection drops the presence state still displays as online . I read in the tigase forums that this is the typical behavior . It takes by default about 10 minutes to update the status . But we all know that chat apps like Gtalk used to show presence correctly in this type of situations . So my questions are : .. . .. . 1 . Is this normal in XMPP What trick hack workaround will help me overcome this I have already tried editing the init.properties file and restarting for a timeout of 10s but still no response .. . .. . 2 . Is tigase the correct answer My user base would be around a couple of thousand users max if this starts up and it would not matter to change into a more simpler XMPP server 3 . Will requesting presence for a peer force the server to re-check the connection status of users will that trigger any presence updates My client library is Asmack . if that helps .. . .. . Thanks in advance : .. . Answer : I m new to xmpp in fact and I try to use tigase as client lib and openfire as server and in the simple official example if client use disconnect method of class tigase.jaxmpp.j2se.Jaxmpp the status shown in the server of this client will be offline i.e . not in the client list otherwise the status will be online for long time after client leave . I don t know whether openfire and tigase use the same mechanism on this kind of client leave . Comment : I downloaded the source for tigase and changed the timers manually in it s client-side communication . I was able to achieve this with those timers . I think the c2s XXXX settings in init.properties can be tweaked to do the same . But this will load the server for large implementations . Comment : @tdevinda Sorry that I didn t learn more about tigase client since then . Documents are not mature compared to that of aSmack . Comment : no worries . I m still to replicate this on another server . I will post the results as soon as I finish . Comment : @tdevinda Cool Good luck to you .", "Question : I am making a chat system and am new to xmpp technology.For server I am confused among ejabbered openfire or tigase.I don t know erlang.And am good at java . I am looking in a case where I have to change a user roster again and again everytimes a user logged in.And that too completely.So I am thinking to control user roster by myself and not by xmpp server.Morever I want to control what to do when a user went idle busy . And many more.And for security it will be great if it can be done on server-side rather than client-side . so how should I customize the xmpp server.And as I need to customise a lot which server should I use Based on how easy its to learn them and customise them .. . Answer : I have done similar kinds of customization in Tigase . I will recommend you to choose Tigase if and only if you are looking for high scalability . For Tigase scalability look at Scaling Tigase XMPP server on Amazon EC2 https : stackoverflow.com questions 8670234 scaling-tigase-xmpp-server-on-amazon-ec2 8672592 8672592 . The other part of Tigase is you need to dig into the code on your own there isn t much help available else than Tigase http : www.tigase.org offical website . In openfire you can get much community support in term of blogs and tutorials as compared to Tigase . But openfire isn t salable as Tigase . Also Openfire has a wide range of plugins available . One more thing about Tigase is that Tigase maintains in memory rosters once user gets login .", "Question : I m actually trying to find the best way to write a simple XMPP server or find one that leaves a really small foot print . I only care about the core features of XMPP statusing messaging group messaging . Also learning about XMPP protocol at the moment so please bear with me if i m saying something that is naive . So currently open fire is being used in our application . It s really heavy and has a lot of features that aren t necessary for our needs . I ve looked at tigase which is another XMPP server that leaves a smaller footprint . I also looked at apachi mia framework which contains or has an extension module vysper - XMPP server . I ve tried to google reviews on this when compared to other servers but can t find that much information . In general I m looking for the best way to implement a simple XMPP server either from scratch or from an already built library framework in java which leaves a smaller foot print then open fire . Interested in getting more pro cons with vysper in comparison to openfire and tigase as well . Any advice appreciated Thanks D Comment : So the question is How to implement a simple XMPP server in java Comment : Yeah sorry if that wasn t clear . I want to create a simple XMPP server handles status multi-chat . I need this to work with XMPP clients like SPARK and others out there . I plan to bridge this server with another internal chat program . I need something that is light weight smaller and less complicated then open fire . Comment : Then I suggest you edit your post and put the actual question in the title .. . Answer : I can talk for Tigase only as I am Tigase team member . For basic XMPP features Tigase binaries take no more than 1.5MB and if necessary it could be reduced to something below 1MB . We run periodic tests with small memory and all the basic features work fine even if you run Tigase with 10MB of RAM of course for no more then a few dozen online users . I think this is quite small foot print . We put a lot of effort on optimizing and testing . It is also designed to easily integrate with other systems so this is the way to go : - Of course I am biased towards Tigase which is understandable . Please wait for some more independent opinion .

Not sure why only localhost works and not bib as domain names for the tigase server . Platform : Windows 8 Version : tigase-server-5.1.5-b3164 .. . .. . Any advice appreciated Thanks D .. . Answer : This something really small is probably the domain-name . I think this BIB domain may not be recognized and the client cannot connect to the server because it does not know where to connect . Is the client showing you any error message Also what version of the Tigase server do you use Some past versions had problems with uppercase characters in the domain-name . Please use all lowercase characters in domain-name in both the Tigase configuration and in the client configuration for the user s JID . You can also enable debug mode so it shows you more of what is going on in the server . You have to check log files to see client s connections attempts . And the last thing - you run Java with default memory settings for the Tigase server . This is fine only for development system . For any production system please refer to original startup files for recommended settings . Comment : Thanks for the response . I ve updated my entry . localhost works but bib lowercase doesn t . I m using tigase-server-5.1.5-b3164 and i m where would i find the psi connection logs . The tigase-server logs doesn t report anything when i try to register a domain with psi .

Answer : K so I wasn t thinking and my knowledge of network IP is lacking . On windows you need to register the domain-name with the host file aka configure your window network to recongize the domain .. . .. . To find your host file : http : www.jafaloo.com windows-hosts-file .. . .. . Add whatever domain you want to use . For more information on what a host file does : http : en.wikipedia.org wiki Hosts 28file 29 .. . .. . This made everything work .", "Question : I am testing Tigase by using Tsung . My first test script would be only registering users on the Tigase server . But I have a strange problem of Tigase duplicating register requests for some user IDs . Take a look at the tsung.dump file below . The register request for user 43-tsung-user-2 is repeated twice . First time it is successful the second time Tigase returns conflict error 409 meaning the user is already registered . My test should take 30 seconds with users coming on 10 seconds intervals . Therefore 3 users should be created in the database . After the test finishes I can only see 2 users which is also what tsung.dump is alredy saying . Why is tsung repeating request for some users Tsung behaves similar no matter what the load is . If i raise the load numbers I will receive the similar behavior . Most of the time the number of successfully registered users will be around the half of tsung generated user count . Below is my tsung.xml .. . Answer : Tsung plays the scenario at random and will reuse some user ids . It means that each time a user is selected to play a scenario there is a risk of conflict if this is the second time that user id is used by Tsung . Unless you would like to specifically load test the client registration I would recommend to pre-create your userbase directly in Tigase . That way you can remove the registration part from you scenario and avoid registration conflicts . Comment : Wow . I would never conclude this from reading tsung docs tsung.erlang-projects.org user-manual http : tsung.erlang-projects.org user-manual conf-options.html xmpp-jabber-options . Thank you a lot .

You have to connect from through an admin account to the Tigase server browse service-discovery and then execute command on the Statistics provider component . I recumbent Psi client for this . 2 . Another way is to connect via JMX protocol using JConsole or similar application . Then you can collect all the Java statistics plus the Tigase provides own bean to browse it s statistics or just download them all it might be 1 000 or more metrics from the server . 3 . Also through JMX but might be more convenient using our utility class : JavaJMXProxyOpt . You can write a very simple command-line tool which collects Tigase statistics and dumps it to a text file .

Answer : I have recently been involved in studying an existing Tigase implementation that is being used as a chat room for all the users that connect to the server . Tigase version : 7.0.2 . Now in the current implementation we are registering the user through some dedicated PHP API that in turn makes use of Tigase ad-hoc commands .

Help me to solve this issue . Comment : when user A sends 3 messages to user B offline before user B come online check your database-table don t remember the name and make user there exists 3 xml stanza related to your 3 messages .... . .. . Answer : I faced the similar problem on client-side we can t do anything for that as XMPP Tigase server automatically returns all the offline messages when user comes online . There might be some problem in Tigase server which is not returning the first message . Because all the offline messages you will receive in .. . - void xmppStream : XMPPStream sender didReceiveMessage : XMPPMessage message and it can be checked first offline message is not returned by server .", "Question : I met a problem in my project.I used tigase to push message to android client but sometimes we should push more than 1000 users s notices at one time . Using smack api to implement this is too slow .Is anyone has new method to do this Can I add a http api to send broadcast message using tigase .. . Answer : There is REST API available in Tigase but why do you think it would be faster than using XMPP This actually depends on how you do this . Using admin ad-hoc commands either via standard XMPP or REST API you can submit 1000 or more notices with a single call . Assuming you have a list of all recipients beforehand . You can also send a message to all online users with a single admin ad-hoc command .

Answer : I am quite new to XMPP with background in Java development . We are using Tigase XMPP server through which XMPP clients on Android and iOS Apps communicate text messages there are Android and iOS developers in my team .

Can anyone please let me know if there is any XEP available for it Or any standard which can help me in guaranteed message delivery . What if i maintain a queue of every outgoing packet in XMPP and later on when i receiver delivery report from client . At that time i can cross check messages which are not delivered . I am using Tigase Please if you guide me about which is the best place for queueing and cross checking of delivery report with messages .. . .. . Thanks .. . Answer : I am afraid there is not simple answer to your question . It mostly depends what QoS means for you and what you need . I suggest you read this forums topic where your question is discussed and I think a good explanation is provided : https : projects.tigase.org boards 4 topics 313 .. . .. . In short there are quite a few mechanism in Tigase for different kinds of QoS requirements so you have to know which one to use . Comment : thank you so much for your contribution .", "Question : I m developing a chat application using Tigase server in the background for providing the XMPP communication . Besides that I m using smack asmack as a library in my application . With every message send between the users for the sake of the functionalities I want to implement I m including package extensions via smack s Presence.setProperty method which are correctly send if both of the users are online . When one of the users is offline the Tigase server saves that message and then delivers it when the user becomes online again . The thing is that Tigase don t save the message including the packet extensions so when the user is online again it receives only parts of the message send . I found the Tigase source and found the place in the OfflineMessages class part of the xmpp.impl package where I need to insert a line of code in order for msgoffline plugin to save the offline messages using extensions . What is the easiest way to override the OfflineMessages class in Tigase jar file without building the whole source code of the project I m using Tigase-5.1.5-b3164 version on ubuntu-server and Eclipse as IDE . Comment : Which line of code is it that you want to insert in OfflineMessages.java Comment : I m trying to do what Artur said .. . Answer : I do not know Smack library hence I do not know what Presence.setProperty method does . But if it does something to a presence packet adding an extra payload to the presence status then this will not be saved to offline message storage because... . presences are not stored in offline message storage . If you want to modify OfflineMessages to make it store more different data than it stores now like a specific presence packets then there is a method : savePacketForOffLineUser with a big IF at the beginning . This is where the decision is made on what to store in an offline storage . But please be careful not to store ALL presences it will kill your service and your database . The best way to add your own plugins is to make a copy of the existing Tigase plugin OfflineMessgae modify it to your preferences change a name of the plugin and ID of the plugin . Then you just put a jar with your code into Tigase jars directory and modify configuration to load your plying instead of the default one .

Answer : I had the same problem with the Tigase server and Asterisk your problem is that you set : .. . .. . config in your xmpp.conf . This option causes auto creation of many nodes if you take a look at tig nodes in the Tigase database you will see that many nodes have been created . You must comment this option . Afterward you must redeploy your Tigase SQL schema or you have to delete all those nodes Then everything will be fine . By looking at the debug output of res xmpp module in the Asterisk CLI you will see that res xmpp will try to subscribe to many nodes at once and this causes confusion because many nodes with the same name exist and server will return 409 and 501 errors .

Lets say we ve selected ones we want to send a message to and we got ourselves a huge array of user JIDs 20k at this point . We ve got a deamon running in the background sending one message at a time to each user stopping for a minute after sending 2000 of messages 2500 minute limit . We are using xmpp4r as a client that handles sending messages . Every user has same @xmpp.address . body is the same in every message . Our tigase logs because thats what we re using show that the messages did actually hit the jabber server and were sent to appropriate users one at a time . The issue we re experiencing is that although everything seemed fine only a part of users actually got the message . for example at one point considering 100 first messages sent - 1..20 and 91..100 got delivered the middle 70 did not get delivered at all we improved couple of things in the meantime but this still might be a clue . We tried creating an array of 10000 duplicated JIDS jids of couple of users were duplicated thousands of times and every single message got delivered and in the right order . We already spent a couple of days trying different scenarios and are starting to run out of ideas what might be going wrong . Got any idea s what we might have missed .. . Answer : I am form Tigase team . First thing I recommend to use our online forums as this is where we normally respond to questions . We may not see questions posted here . Anyway.. . There are some details not included in your post . 1 . What do you connect and how Over standard XMPP connection over Bosh something else 2 . What do you mean by duplicated JIDs How did you duplicate JIDs 3 . Are all the users for which a message is sent online during the test 4 . If you can see message in Tigase logs you should also see what happens to it . Was it submitted to network socket for delivery to a client 5 . What kind of HW did you use Is there a chance that the server was overloaded and simply dropped some messages Seems unlikely if you talk about 100 messages and 70 of them not delivered . 6 . How do you actually know that a message was not delivered and are you sure the client user was connected at the time" ] }

However I can t figure out why the last variable appears to be on top of the second one.I would like the first variable covering the second variable as it is and the second one covering the third one which is the problem here . What does control the depth of each variable and is there a way to change this Histogram presenting my 3 variables as you can see the black variable appears on top of the dark grey one which is great but the light grey variable also appears on top of the dark grey variable instead of under it http : i.stack.imgur.com Bh5zi.jpg .. . .. . Many thanks . .. . Answer : Although I still don t know the correct answer to your question I was interested in this topic and tested some of my data varying colors and width . In my cases the third bar covered the second and the second bar covered the first one always . A tricky part is that it is very hard to tell which one covers which without adding line colors or decreasing width . I guess there might be a chance that actually your third bar covers the second and the second bar covers the first one like my cases .

Using position stack in geom-text or creating a new variable for the position on the y axis . Comment : @aosmith Thanks . Adding position stack gives the same . I looked at other SO-entries about this issue for example your link . The main difference is that I use option position fill in geom-bar . Comment : Did you add position stack to geom-text not geom-bar That option works fine for me if I add it to your code . You may find you need to do something about the really small percentages . Something like label ifelse p .05 NA p2 might suffice . Comment : I put it erroneously within aes of geom-text . Now it works . Thank you very much . If you write your answer into the answer field I can vote it . Comment : That sounds right as I believe position stack relies on the order of the dataset in the newest versions of ggplot2 see here https : github.com hadley ggplot2 issues 1593 . .. . Answer : To avoid creating the position values yourself you can use position stack in geom-text as in this question http : stackoverflow.com questions 6644997 showing-data-values-on-stacked-bar-chart-in-ggplot2 . As you noted in the comments the dataset must be ordered by the fill variable to get the stacks in the correct order to match the bar stacks . enter image description here http : i.stack.imgur.com 9EG0y.png .. . .. .

However I can t figure out why the last variable appears to be on top of the second one.I would like the first variable covering the second variable as it is and the second one covering the third one which is the problem here . What does control the depth of each variable and is there a way to change this Histogram presenting my 3 variables as you can see the black variable appears on top of the dark grey one which is great but the light grey variable also appears on top of the dark grey variable instead of under it http : i.stack.imgur.com Bh5zi.jpg .. . .. . Many thanks . .. . Answer : Alright For those struggling with the same problem I eventually found the way this works . The order of the columns horizontally is determined alphabetically by the name of the three variables in my case F is the first bar N is the second bar and XFe is the last bar but the depth of each variable is determine by they order of appearance in the dataset with the first variable appearing being the bar the most at the back and the last appearing variable being the bar the most in front see attached pictures for example I put the same colour to the 3 variable to make it more obvious . In my original version the order of appearance of my variables in the dataset was N F and XFe and here is what s happening when I change the order of the dataset : .. . .. . Version with dataset reorganised for having the order of appearance of the variables as F N and XFe http : i.stack.imgur.com dUSdQ.jpg .. . .. . Version with appearance of the variables in the dataset as F XFe and N http : i.stack.imgur.com u77ye.jpg", "Question : This is actually two questions in one not sure if goes against SO rules but anyway . First question is how can I force a geom-text to fit within a geom-bar dynamically according to the values plotted .. . .. . Looking around the solutions I found were changing the size of the label . That certainly works but not for every case . You can change the size for a specific plot to make the text fit within the bar but when the data changes you may need to manually change the size of the text again . My real-life problem is that I need to generate the same plot for constantly changing data daily so I cannot really manually adjust the size for each plot . I tried setting the size of the label as a function of the data . It kinda works not perfectly but works for many cases . But here s another problem even when the label fits within the bar resizing the plot messes everything up . Looking into it I also found in the ggplot documentation http : docs.ggplot2.org current geom text.html that .. . .. . labels do have height and width but they are physical units not data units . The amount of space they occupy on that plot is not constant in data units : when you resize a plot labels stay the same size but the size of the axes changes . Which takes me to my second question : Is it possible to change this default behaviour and let make the labels resize with the plot And also let me refine my first question . Is it possible to force a geom-text to fit within a geom-bar dynamically setting the size of the text using a clever relation between physical units and data units So to follow good practice here s my reproducible example : .. . .. . This code produces this plot : .. . .. . enter image description here http : i.stack.imgur.com 112SS.png .. . .. . If I simply resize the plot labels stay the same size but the size of the axes changes http : docs.ggplot2.org current geom text.html thereby making the labels fit into the bars now perhaps labels are even too small . enter image description here http : i.stack.imgur.com m0g3U.png .. . .. . So this is my second question . It would be nice that the labels resize as well and keep the aspect ration in relation to the bars . Any ideas how to accomplish this or if it is possible at all Ok but going back to how to fit the labels within the bars the simplest solution is to set the size of the labels . Again this works as shown below but it is not maintainable nor robust to changes in the data . enter image description here http : i.stack.imgur.com TKjQr.png .. . .. . For example the very same code to generate the plot with different data yields catastrophic results . enter image description here http : i.stack.imgur.com ezDNs.png .. . .. . And I can go on with the examples setting the size of the labels as a function of the number of categories on x-axis and so on . But you get the point and perhaps one of you ggplot2 experts can give me ideas . .. . Answer : one option might be to write a geom that uses a textGrob with a custom drawDetails method to fit within the allocated space set by the bar width . enter image description here http : i.stack.imgur.com Y01qi.png Comment : awesome .. . still trying to understand how it works cause I only know the basics of ggplot2 but the code works smoothly and addresses both issues : it perfectly fits the text within the bars and the text resize along with the plot . I really did not think it was possible . Many thanks", "Question : I know 3D Barcharts are a sin . But i m asked to do them and as a trade-off i suggested to only make a border with a slightly darker color than the bar s on the top and the right side of the bar . Like that the bars would have some kind of shadow urgh but at least you still would be able to compare them . Is there any way to do this .. . Answer : As you already said - 3D barcharts are bad . You can t do it directly in ggplot2 but here is a possible workaround for this . First make new data frame that contains levels of clarity and corresponding count for each level . Then in ggplot call use new data frame and clarity as x values and V1 counts as y values and add geom blank - this will make x axis with levels we need . Then add geom rect to produce shading for bars - here xmin and xmax values are made as.numeric from clarity and constant is added - for xmin constant should be less than half of bars width and xmax constant larger than half of bars width . ymin is 0 and ymax is V1 counts plus some constant . Finally add geom-bar stat identity above this shadow to plot actually barplot . enter image description here http : i.stack.imgur.com WTVyv.png Comment : +1 for a workaround but Stephen Few is crying and my eyes are bleeding .

Here I try to give a idea on sizing based on web read and research . In CSS3 there are sixteen different units by which you can measure the size . Understanding sizing in CSS .. . .. . There are two types of measurement units : .. . .. . relative lengths and absolute lengths . relative lengths : .. . .. . Relative length units specify a length relative to another length . The relative units are : em ex ch rem vw vh vmin vmax . They are mainly useful when the output media has dynamic size like mobile device laptop . absolute lengths : .. . .. . these are fixed in relation to each other and anchored to some physical measurement . The absolute units are : px mm cm in pt pc .They are mainly useful when the output environment is known . As you known we got two types of measurement units and two types of media output : screen and print and someone might to add handheld also but I take it in screen . Absolute length units .. . .. . px : One device pixel dot of the display . 1px is equal to 1 96th of 1in .. . .. . mm : One millimeter . cm : One centimeter 10 millimeters . in : One inch 2.54 centimeters . pt : One point which is 1 72 of an inch . pc : One pica which is 12 points . Absolute length units are best suited for paper low-resolution screen or has a closed view from eyes to screen . Relative length units .. . .. . em : font-size of the element .. . .. . : percentage values are always relative to another value for example a length .. . .. . ex : x-height of the element s font 1ex 0.5em in many fonts .. . .. . ch : width of the 0 ZERO U+0030 glyph in the element s font .. . .. . rem : font-size of the root element .. . .. . vw : viewport s width 1 100th of the width of the viewport . vh : viewport s height 1 100th of the height of the viewport . vmin : minimum of the viewport s height and width .. . .. . vmax : maximum of the viewport s height and width .. . .. . The Difference Generally the relation between the measurement units is as follows : .. . .. . The absolute units cm mm in pt and pc will appear as exactly that size in CSS as everywhere else . They are not recommended for use on screen because screen sizes vary so much . For this reason the relative length units are best suited for the web developers . In web authoring em and percent are most common unit . Since CSS3 you will find rem unit that appears quite frequently . em percent and rem means they are related to the size . Because em inherits size from its parent element makes it a little difficult to sizing if the user has a big size on a big screen or a small size on a handheld device the sizes will be in proportion . If we convert 1em equals 10px instead of the default 16px then we sizing the text in list like .. . .. . the problem with em -based sizing is that the font-size compounds . So rem is a new unit is in development to make it even easier to make style rules that depend only on the default font-size . That means that we can define a single font-size on the html element and define all rem units to be a percentage of that . Unlike the em which may be different for each element the rem is constant throughout the document . What s about keywords I m not using the keywords unit although keyword sizing is pretty consistent across browsers and platforms because it s can not handle the typography as the choices are fairly limited . Conclusion .. . .. . Now the em and percent units are standard for sizes on the web but in practice the rem unit seems to provide a more consistent and accessible display for multi screen sizes . Other units like vh vw in deep development it s need more time to testing and appearing in web authoring .

I looked at this question from Stack Overflow but it made the units look even more similar . How does vw and vh unit works http : stackoverflow.com questions 24876368 how-does-vw-and-vh-unit-works .. . .. . The answer specifically says .. . .. . vw and vh are a percentage of the window width and height respectively : 100vw is 100 of the width 80vw is 80 etc . This seems like the exact same as the unit which is more common . In Developer Tools I tried changing the values from vw vh to and viceversa and got the same result . Is there a difference between the two If not why were these new units introduced to CSS3 Comment : What vw vh does is remove the dependency on any parent and allows sizing based on the viewport size . .. . Answer : 100 can be 100 of the height of anything . For example if I have a parent div that s 1000px tall and a child div that is at 100 height then that child div could theoretically be much taller than the height of the viewport or much smaller than the height of the viewport even though that div is set at 100 height . If I instead make that child div set at 100vh then it ll only fill up 100 of the height of the viewport and not necessarily the parent div .

Answer : According to the specs https : drafts.csswg.org css-values-3 viewport-relative-lengths the viewport relative length units do not take scrollbars into account and in fact assume that they don t exist .

Viewport computing http : en.wikipedia.org wiki Viewport Comment : Well then I might have a wrong idea as to how the vh works tbh . In my opinion it would be rendered to the exact same positions . Comment : The viewport is supposed to represent the physical space of the display . Zoom doesn t change the physical space of the display rather changing the contents of the display . Think of it as looking at something through a magnifying glass . It doesn t actually change the size of the physical object just the size at which it s being displayed . Comment : So is there any other reasonable way of achieving this Comment : Something like this jsfiddle.net TnY3L 5 http : jsfiddle.net TnY3L 5 .. . Answer : The vh and vh units are a measurement relative to the viewport size . 1vh is 1 of the current viewport height so 100vh is always 100 height . No matter how much you zoom in and out the viewport is still the same size . When you zoom in you scale up the entire document but not the viewport . It s logical that the space between elements increases as you zoom in the page if that space is not defined in viewport-units as well . Because the other elements don t increase it takes the document out of proportions . If you want to create elements that scale as you zoom in try using the rem unit . This is relative to the body s font-size so as you zoom the page in every value expressed in rem will scale accordingly . Comment : if you take a div give it 200px width and zoom in will it scale If yes your explanation is wrong . Comment : Good point I was a bit too simplistic", "Question : I was under the impression that the units vh and vw deal with mobile-browser zooming in but apparently that s not the case and I think I am beginning to understand why . Zooming in does not change the viewport at all but merely shows the user only a part of the viewport despite the name viewport . Basically there is a difference between what you can see and the viewport . I don t know if distinguishing those two really makes sense but that s how it seems to be . The question is : How else do I react in my stylesheet to zoom changes For example I have some html element with a width and it fits on the screen of a mobile phone . Now the user zooms in doing that two finger gesture moving the fingers away from each other . The size of the element should stay the same relative to what the user sees but text should get bigger because it might be the reason why the user zooms in . Maybe they couldn t read it before or want a link-to be bigger so that they can click more easily on it . How would I do such a thing I ve read about @viewport stuff but it s not really supported yet and also poses the question when to use which viewport size how to make it as fluent as when you use vh and vw on a destop browser Simple limiting up to so and so much px of width won t do . Defining a mathematical function for how much the element changes its size relative to what one can see and how much the text-size changes would be great but is probably not possible to have . .. . Answer : On mobile-devices the text-size-adjust property allows Web authors to control if and how the text-inflating algorithm is applied to the textual content of the element it is applied to . As this property is non-standard it must be used prefixed : -moz-text-size-adjust -webkit-text-size-adjust and -ms-text-size-adjust . Browsers on smartphones don t display web pages using the same algorithms as browsers rendering web pages on desktop machines . Instead of laying out the web page at the width of the device screen they lay it out using a viewport that is much wider than the device screen usually of 800 or 1000 pixels wide . One of two possible methods is used to map back to the original device coordinates : either a smaller window is then used to display on the device screen only part of what is actually being rendered or the viewport is stretched to the size of the device .

I started working on web-application programming just over a year ago and thankfully discovered nodeJS which made web-app creation feel a lot more like traditional programming . Now I have a node.js app that I ve been developing for some time that is now running in production on the web . My main confusion stems from the fact that I am very new to the world of the web development and don t really know what s important and what isn t when it comes to monitoring my application . .. . .. . I am using a Joyent SmartMachine and looking at the analytics options that they provide is a little overwhelming . There are so many different options and configurations and I have no clue what purpose each analytic really serves . For the questions below I d appreciate any answer whether it s specific to Joyent s Cloud Analytics or completely general . QUESTION ONE .. . .. . Right now my main concern is to figure out how my application is utilizing the server that I have it running on . I want to know if my application has the right amount of resources allocated to it . Does the number of requests that it receives make the server it s on overkill or does it warrant extra resources What analytics are important to look at for a NodeJS app for that purpose using both MongoDB and Redis on separate servers if that makes a difference .. . .. . .. . .. . .. . QUESTION TWO .. . .. . What other statistics are generally really important to look at when managing a server that s in production I m used to programs that run once to do something specific e.g . a raytracer that finishes running once it has computed an image as opposed to web-apps which are continuously running and interacting with many clients . I m sure there are many things that are obvious to long-time server administrators that aren t to newbies like me . QUESTION THREE .. . .. . What s important to look at when dealing with NodeJS specifically What are statistics analytics that become particularly critical when dealing with the single-threaded event-loop of NodeJS versus more standard server systems I have other questions about how databases play into the equation but I think this is enough for now.. . Comment : Very constructive question . Nice Comment : Thank you very much : .. . Answer : Node.js is single-threaded so you should definitely start a process for every cpu your machine has . Cluster http : nodejs.org docs latest api cluster.html is by far the best way to do this and has the added benefit of being able to restart died workers and to detect unresponsive workers . You also want to do load-testing until your requests start timing out or exceed what you consider a reasonable response time . This will give you a good idea of the upper limit your server can handle . Blitz http : www.blitz.io is one of the many options to have a look at . I have never used Joyent s statistics but NodeFly http : apm.nodefly.com and their node-nodefly-gcinfo https : github.com NodeFly node-nodefly-gcinfo readme is a great tools to monitor node processes .

If moving the cluster.on exit listener into the if cluster.isWorker block does not resolve the issue then I think you should open an issue on Github https : github.com joyent node issues as I can t see why the event would be emitted in any workers . Edit : It was indeed a bug https : github.com joyent node pull 6917 . Comment : will do is that the only way to get this resolved use cluster github.com joyent node issues 6915 https : github.com joyent node issues 6915 Comment : If you tried my suggestion first then you didn t update your code for the github issue .

Right now my main concern is to figure out how my application is utilizing the server that I have it running on . I want to know if my application has the right amount of resources allocated to it .

QUESTION TWO .. . .. . What other statistics are generally really important to look at when managing a server that s in production I m used to programs that run once to do something specific e.g . a raytracer that finishes running once it has computed an image as opposed to web-apps which are continuously running and interacting with many clients . I m sure there are many things that are obvious to long-time server administrators that aren t to newbies like me . QUESTION THREE .. . .. . What s important to look at when dealing with NodeJS specifically What are statistics analytics that become particularly critical when dealing with the single-threaded event-loop of NodeJS versus more standard server systems I have other questions about how databases play into the equation but I think this is enough for now.. . Comment : Very constructive question . Nice Comment : Thank you very much : .. . Answer : Whichever the type of web app NodeJS or otherwise load-testing will answer whether your application has the right amount of server resources . A good website I recently found for this is Load Impact http : loadimpact.com . The real question to answer is WHEN does the load-time begin to increase as the number of concurrent users increase A tipping point is reached when you get to a certain number of concurrent users after which the server performance will start to degrade . So load test according to how many users you expect to reach your website in the near future . How can you estimate the amount of users you expect .. . .. . Installing Google Analytics or another analytics package on your pages is a must This way you will be able to see how many daily users are visiting your website and what is the growth of your visits from month-to-month which can help in predicting future expected visits and therefore expected load on your server . Even if I know the number of users how can I estimate actual load .. . .. . The answer is in the F12 Development Tools available in all browsers . Open up your website in any browser and push F12 or for Opera Ctrl+Shift+I which should open up the browser s development tools . On Firefox make sure you have Firebug installed on Chrome and Internet Explorer it should work out of the box . Go to the Net or Network tab and then refresh your page . This will show you the number of HTTP requests bandwidth usage per page load So the formula to work out daily server load is simple : .. . .. . Number of HTTP requests per page load X the average number of pages load per user per day X Expected number of concurrent users Total HTTP Requests to Server per Day .. . .. . And.. . Number of MBs transferred per page load X the average number of pages load per user per day X Expected number of concurrent users Total Bandwidth Required per Day .. . .. . I ve always found it easier to calculate these figures on a daily basis and then extrapolate it to weeks and months . Comment : thanks for this answer - i gave the other one the bounty though because it addresses node.js specifically which is more of what I m interested in .

Comment : Very constructive question . Nice Comment : Thank you very much : .. . Answer : We have been running node.js in production nearly an year starting from 0.4 and currenty 0.8 series . Web app is express 2 and 3 based with mongo redis and memcached . Few facts . node can not handle large v8 heap when it grows over 200mb you will start seeing increased cpu-usage .. . node always seem to leak memory or at least grow large heap size without actually using it . I suspect memory fragmentation as v8 profiling or valgrind shows no leaks in js space nor resident heap . Early 0.8 was awful in this respect rss could be 1GB with 50MB heap . hanging requests are hard to track . We wrote our middleware to monitor these especially as our app is long poll based .. . .. . My suggestions . use multiple instances per machine at least 1 per cpu . Balance with haproxy nginx or such with session affinity .. . write midleware to report hanged connections ie ones that code never responded or latency was over threshold .. . restart instances often at least weekly .. . write poller that prints out memory stats with process module one per minute .. . Use supervisord and fabric for easy process-management .. . .. . Monitor cpu reported memory stats and restart on threshold Comment : so does this imply that if I have a 2GB RAM machine running 10 processes across 10 cores hypothetical it would be a lot more effective to add a new machine of equal capacity as opposed to doubling the RAM and CPU power Comment : I don t know . All I know that you need to have several small instances of node per server to utilize the machine capability . Scaling is dependent on your app and network design .", "Question : I would like to know how can I write something small like node in native lanuage c cpp . I read that c c++ experts developed node.js and made it available with javascript interface . This interface is much much simpler to start with node.js applications . This is not about re-inventing the wheel only learning but I want to learn understand the way where to start if I want to create a server that work like node it is not performance or scalability or simplicity oriented . nothing like that . Any book or any c cpp topic that will help me to start with websockets broadcasting data and such important features of node . I am new to c cpp also but need to understand what is making node such a strong technology . Any other solutions than taking source code of node.js Comment : Another project you might be interested in is nginx http : wiki.nginx.org Main pronounced engine-x . It s an open-source event based web server also written in C C++ . You can find the source code here https : github.com git-mirror nginx Comment : @BrandonBoone : thanks for the reply but how can I write c cpp servers more stronger than writing only chat servers . Comment : The source code is available for all of Node.JS . I m not clear why you wouldn t want to start there . Asking for books tutorials etc . isn t a good match for StackOverflow . Comment : @WiredPrairie : yeah thanks node.js source code . In future I will take care of question and will not ask for books tutorials references . .. .

Therefore the solution I found was to use the OCI8 Functions http : php.net manual en function.oci-parse.php of PHP . Like this i could use oci parse to directly query against the DB or rather call a PL-SQL procedure which is what I finally decided to do . because of the sql functions complexity and the division of task inside my work group .. . .. . Now I can not make use of many of the advantages of using CakePHP models but It was the only way .", "Question : We want to use the FPDF library in one of our controllers . We created the following files : .. . .. . Right before the controller class we try this : .. . .. . But it fails every time . What are we doing wrong Comment : Have you tried changing the name of the file fdpf wrapper.php to FpdfWrapper.php and try with just App : : uses FpdfWrapper Lib Also I m sure you ve read this http : stackoverflow.com questions 11450519 cakephp-i-cant-get-appuses-to-find-my-class but couldn t it be an error with the file syntax logic etc instead of cakephp not finding the class If that doesn t work can you be more specific and tell what fails everytime and how Class not found error or something else Comment : @Nunser it was a class not found error . We re currently getting it to work with App : : import Vendor bla bla . Not sure whether Vendor or Lib is the most appropriate place for this .

Is it and changing the name of the file to what I pointed out did not work .. . Answer : First of all package paths must be registered in order to be used with App : : uses http : book.cakephp.org 2.0 en core-utility-libraries app.html App 3a 3auses and Lib Fpdf is no such one by default only the core packages are registered .

For example AssetHelper : .. . .. . The helper fatal errors of course . Does anyone know how to access those attributes in 2.0 without creating too much overhead in the process Are the AssetHelper and other such classes outdated if they try to access the View from inside a Helper .. . Answer : The new way of accessing the View from a Helper in 2.0 is this- View which is protected . You can see it on the Helper API page http : api20.cakephp.org file Cake View Helper.php . I looked at the AssetHelper on Github https : github.com mcurry asset and it is outdated . It still retrieves the view from the ClassRegistry instead of the new method . It also accesses the scripts attribute of the old 1.3 View class which wasn t actually private . I think you re correct that the change to real visibility declarations has broken this use . Just brainstorming but I wonder if you could make your own View class that has a getter for the scripts attribute like this- View- getScripts . I know that in 2.0 they added a slick ability to alias core classes http : book.cakephp.org 2.0 en appendices new-features-in-cakephp-2-0.html highlight alias aliasing while I think this is restricted to helpers components and behaviors it s something to think about . Hope that helps . Comment : yes that definitly helps . I was thinking in a similar direction . too bad the core classes don t allow access to the scripts or other protected attributes for that matter . it s not like those must be kept secret from the developers :", "Question : After a few times adding Containable Behavior to my various model classes I have a good mind to simply chuck the line into AppModel instead and thus make every model Containable . Which then makes me wonder is there any situation where it is not desirable or counterproductive for a particular model to have Containable Behavior .. . Answer : Containable can be dangerous b c Cake acts in an extremely inefficient manner in order to get the nested results . This site explains it well.. . .. . .. . http : www.endyourif.com cakephp-containable-statement-pitfalls .. . .. . Basically though the nice array you are getting back is the results of many different queries while your best performance may come from using a single query with joins . The convenience of containable is undeniable though . Comment : Well after reading the post you linked a statement in particular came to my notice : After doing some research it is clear that CakePHP will not be solving this issue in 1.2.x . I have heard rumors that it will be addressed in version 2 though which I will be quite excited for . Now the question is where exactly can I read about this in official source Because I doubt it concern still exists . It d seem very lame to perform 100s Select s instead of a simple JOIN . By the way reference to 2.x docs and 3.x docs will be good .", "Question : There seems to be very few to no up to-date resources on integration of Facebook login with the cakephp Auth component online . I have found the following resources : .. . .. . 1 . Old Bakery Article http : bakery.cakephp.org articles fsiebler 2010 08 23 integrating facebook connect using cakephp-1.3 and an older version of Facebook SDK .. . 2 . Cakephp Plugin by webtechnick https : github.com webtechnick CakePHP-Facebook-Plugin that seems to be in development .. . .. . Other than this I found no definitive resources . I wanted the integration to be as flexible without the use of a magic plugin as possible . So after much research I finally baked a decent solution which I am sharing here today . Please contribute as I am rather new to cake . .. . Answer : Integration of Cakephp 2.x Auth with Facebook Auth for seamless user authentication .. . .. . To start off you should read up on the fantastic cakePHP Auth Component http : book.cakephp.org 2.0 en core-libraries components authentication.html and follow the Simple Authentication and Authorization Application tutorial http : book.cakephp.org 2.0 en tutorials-and-examples blog-auth-example auth.html from the cakephp book 2.x Assuming you have also followed the first two tutorials from the series . After you are done you should have managed to build a simple cakePHP application with user authentication and authorization . Next you should download the facebook SDK https : developers.facebook.com docs php gettingstarted and obtain an App ID https : developers.facebook.com apps from facebook . .. . .. . First we will copy the Facebook sdk in to App Vendors . Then we will import and initialize it in the AppController beforeFilter http : book.cakephp.org 2.0 en controllers.html request-life-cycle-callbacks method . We are initializing the Facebook SDK in AppController so that we will have access to it through out the application . Next we will generate the Facebook login URL using the SDK and pass it to the view . I normally do this in the beforeRender http : book.cakephp.org 2.0 en controllers.html request-life-cycle-callbacks method . Note : The above configuration details appId secret should preferably be saved in App Config facebook.php . You should then use cake Configure http : book.cakephp.org 2.0 en development configuration.html . .. . .. . We will update our layout so that we can display this link-to facebook-login for all users who have not logged in . Notice how we have set redirect uri to our applications User login action . This is so that once facebook has authenticated a user we can log him in using cake : : Auth as well . There are various benefits to this including the solution for this question http : stackoverflow.com questions 9137728 cakephp-facebook-integration-logout-issue-with-cakephp-facebook-plugin . When the user clicks the login link facebook SDK will login the user and redirect them to our app Users login . We will update this action for handling this : .. . .. . And we are done Most of the heavy lifting is done by this action as you can see . You should preferably move some of the above code in to UserModel . So here s a summary of what is going on . At first we check if the login request is send from the login form of our application @ Users login . If it is then we simply log the user in . Otherwise we check if the user exists in our database and if he does log him in or create a new user and then log him in . Be careful to verify the user here with more than their email like their facebook id . Otherwise there is a chance the user could change their facebook email and hijack another user of your application . .. . .. . Happy Coding Comment : Hi Shafee I have followed you example however for some reason I get this message 1 out of 10 times . OAuthException : An active access token must be used to query information about the current user do you have any solutions for this Comment : Seems to be a valid approach have not tested yet . So could you mark it as the accepted answer since that s what you ended up using Comment : Thanks man this helped me a lot the only thing I would like to achieve is to have a popup windows of login instead of redirecting to a new url : adding display popup to the getLoginUrl does not seem to work . Thanks Comment : I am unable to get email using your solution Comment : The Facebook SDK changed since I posted this . You should read about what changed in the docs", "Question : Is it possible to define global conditions for Model I have 2 Models : User and Student .

Consider having many users only a few students and a query with a limit - it s quite possible to return only not-students unset all results and therefore return 0 results - even though there are results in the db Comment : true your answer is better", "Question : So I have this query that I am trying to convert to cake ORM and I do not know how to go about it .. . Answer : Inside your Users model : .. . .. . If you re new to using CakePHP 2.x I recommend taking a look at Dogmatic http : dogmatic69.com sql-to-cakephp-find-converter to give you some ideas on converting SQL to CakePHP query syntax . Comment : type join should be type INNER . Also I don t think you need to contain UserOrders this will fetch the hasMany relationship provided it s declared and the class is called UserOrders and not UserOrder following CakePHP conventions .

Comment : I ve moved the site off GoDaddy but the database was not localhost even though it was on GoDaddy as well - they give you a connection-string to use . I have to assume it was rewrite - my other sites used the same databases from GoDaddy without issues - the only difference that I can think is that CakePHP uses rewrites and my other sites don t . Comment : Did you use apache rewrite rules on your other sites with godaddy .. . Answer : I haven t looked into CakePHP 2 but CakePHP 1.3 has a default behaviour of mostly selecting way too much models relations . Say you just want to select the name of the currently logged in user : .. . .. . Depending on your entity relations CakePHP joins tons of other tables usergroups permissions logtables sessions articles etc . while performing the query . Be sure to set recursive to the lowest possible value : http : book.cakephp.org 2.0 en models retrieving-your-data.html Comment : I understand but recursive was -1 and I was running no queries - nothing in AppController nothing in the action...etc . It s considered best practice to set recursive to -1 in your AppModel so I completely agree with your point but in this case it s unrelated .", "Question : I haven t taken a look at Recess PHP Framework in a while but for those that have experience with both frameworks I ask this question : What features does Recess offer over CakePHP 2.x .. .

Answer : Puppet is about Desired State - not Procedural .. . .. . It feels like you are treating Puppet as procedural at the moment and Puppet is more about the desired state . You determine what is installed you shouldn t necessarily ask . So on certain server roles you would say the end state is that you need vSphere and also other software .

And I want to pass this using facter and use it in puppet at such : .. . .. . How can I do this Comment : I created a puppet function and then used eval on the string . .. . Answer : Facter 1.x cannot pass structured-data as fact values . All facts will be coerced into String format .

The challenge is that mongo changed its mechanism for enabling user authentication between version 2.2 http : docs.mongodb.org v2.2 tutorial control-access-to-mongodb-with-authentication and version 2.4 http : docs.mongodb.org manual tutorial enable-authentication and so distinct code must be run in order to give a user authentication credentials to a database .

Is there a way to execute arbitrary code at run time during puppet execution so that I can access mongod --version and decide which method to use to enable user authentication Note : One approach would be to have puppet run a single script to create user credentials and have the script detect the mongod --version at runtime .

I m using the two facts to determine which of multiple .so files is the right one to install : .. . .. . The files that are located in the agent x64 directory can be .. . Answer : You essentially have only two opportunities to execute code on the node : .. . .. . 1 . As part of a Facter fact . As you are aware this happens before puppet applies a catalog so any facts dependent on the results of the puppet run will not be useful until the next run . 2 . As part of a custom provider . You can create a custom type and provider for installing the extensions that checks the node state before deciding what to do . Providers execute on the node and as long as you know the overall provider lifecycle you can make this happen after the PHP install . However this is incredibly complex compared to normal puppet modules . Outside of those options the normal way of doing this would be to enforce the version and configuration of php within your own manifests and then pass that information to here . You should already know the version of PHP and its extensions based on what packages you have installed .

To operate on JSON data from your ruby code you have to deserialize http : stackoverflow.com questions 9055096 from-json-to-a-ruby-hash it into a bona fide Ruby object . Note that your Array contains Hashes so your template needs to be structured differently anyway : Comment : I tried this and it gives following error executing puppet agent -test Error : Could not retrieve catalog from remote-server : Error 400 on SERVER : Failed to parse template config carbon.xml.erb : Filepath : usr lib ruby vendor ruby json common.rb Line : 155 Detail : can t convert nil into String at etc puppet modules config manifests init.pp : 16 on node puppetclient.localdomain Comment : Also note that I run facter -p on my client but it doesn t show any key employees . Is there any problem with my json Comment : No there is a problem with your fact . Solve that first . Comment : I have edited my json Comment : Please read up on External Facts . You cannot just dump your JSON data to etc facts.d . Facter expects to find executable scripts there that can very well output JSON data but it must be in a facter compliant fashion : docs.puppetlabs.com guides custom facts.html external-facts http : docs.puppetlabs.com guides custom facts.html external-facts", "Question : I ve just upgraded my puppet environment from 3.4.2 to 3.4.3 . through puppetlabs apt repos . I was upgrading agent s and master . Doing an agent run leads to following error : .. . .. . Nevertheless I retrieve a catalog from master so the agent run still works and seems to do the things it should do . Or let s say I acutally can t determine if something is going wrong that is related to the error message . However I want to get rid of the Error message . I double-checked version of puppet with puppet --version on agent and master . I use passenger for puppetmaster . Facter has version 2.0.1 . So what did I miss .. . .. . Addition : When running an agent with the previous version 3.4.2 there will be no error message . Any ideas Many thanks for your support . ITL Comment : I just upgraded a few minutes ago and am getting the same message . If I turn off pluginsync it goes away but obviously that s not a fix . Version : 3.4.3-1puppetlabs1 - Broken Client Version : 3.4.2-1puppetlabs1 - Working Client Comment : However it seems that everything is working as it should . The described behaviour occurs when updating from an older version . When installing puppetmaster from scratch tried 2 days ago on a test server everything looks fine . Nevertheless a solution would be very nice here as I don t want to reinstall or migrate my productive server . .. . Answer : The problem your encounter here comes from facter update and the way you use private facts with puppet on version 3.X with facter 2.X.when you want to distribute external facts that was my case . As said in facter 2.2 documentation you need to relocate your facter folder into module tree : .. . .. . The best way to distribute external facts is with pluginsync which added support for them in Puppet 3.4 Facter 2.0.1 . To add external facts to your puppet modules just place them in MODULEPATH MODULE facts.d . So in older versions the path for external facts was : .. . .. . MODULEPATH MODULE lib facter external fact.rb .. . .. . If you change it to : .. . .. . MODULEPATH MODULE facts.d external fact.rb .. . .. . Then you won t encounter the problem any more . Regards .. . .. . -- rustx", "Question : I m working on extending the puppetlabs-mongodb https : github.com puppetlabs puppetlabs-mongodb module to allow for user authentication https : github.com puppetlabs puppetlabs-mongodb issues 36 . The challenge is that mongo changed its mechanism for enabling user authentication between version 2.2 http : docs.mongodb.org v2.2 tutorial control-access-to-mongodb-with-authentication and version 2.4 http : docs.mongodb.org manual tutorial enable-authentication and so distinct code must be run in order to give a user authentication credentials to a database . My initial thought was to create a custom facter fact that basically captured the output of mongod --version but it appears that facter facts are loaded before the puppet manifest is executed . Is there a way to execute arbitrary code at run time during puppet execution so that I can access mongod --version and decide which method to use to enable user authentication Note : One approach would be to have puppet run a single script to create user credentials and have the script detect the mongod --version at runtime . This doesn t seem like a very puppet-y way of doing things but perhaps I am off base on that . What is the best way to handle the need for accessing variables dynamically in puppet facter .. . Answer : The word from @puppetlabs https : twitter.com deanmalmgren status 356795407659044867 is that you can not run ruby code or any other code dynamically during a puppet run . The right way to do this is in the note above with an exec statement that dynamically checks for the mongodb version . For details on the implementation see manifests add user.pp https : github.com deanmalmgren puppetlabs-mongodb blob 527742bc49677153e8aabde81f8137aebfc0ab8a manifests add user.pp and the associated templates add user .erb https : github.com deanmalmgren puppetlabs-mongodb tree 527742bc49677153e8aabde81f8137aebfc0ab8a templates .

The name of the ethernet adapter e.g . eth1 is a parameter of my defined type . When I try to populate a config file through puppet with an erb template which accesses the macaddress facter fact that gives me the mac address for the eth0 interface which is the wrong one in this instance . How can I create a variable in my defined type which takes the value of facter macaddress ethernetinterface where ethernetinterface is defined by a parameter of the defined type .. . Answer : There is a whole family of macaddress facts one for each interface . In your template you can access the variable name that includes a parameter say interface like .. . .. .

Answer : As stated by the documentation http : synopse.info files html Synopse 20mORMot 20Framework 20SAD 201.18.html TITL 86 current version of the main framework units target only Win32 Win64 systems under Delphi and in a preliminary state Windows or Linux under FPC . So you can run a Server on those platforms . But you can write a Client on all Delphi supported platforms by using some dedicated cross-platform client units and generate some code to consume the server ORM and SOA content . To write an OSX or Mobile client using FMX for the UI do not use regular SynCommons.pas mORMot.pas units but the dedicated units as available in the CrossPlatform sub-folder . The documentation is pretty detailed about it .

Comment : Damned if you do damned if you don t . There s not enough documentation . There s too much documentation . Comment : @Arnaud . It s interesting components but I don t understand . General advantages of Delphi is mobile developing . Main advantages of you tools is powerful data-access . Why I can t open demo with multi-tier server and mobile client Comment : and JSONToClientDataSet component is included in mORMotMidasVCL", "Question : mORMot Framework www.synopse.info http : www.synopse.info have add support to WebSockets on pack there is also a demo about WebSockets sample 31 . In this sample the client send a message to server and this reply with a new message to client . I d like use this library to do this : .. . .. . 1 . The client send message to server and send also the IP address without waiting message from server . .. . 2 . The server can send message to single client by IP address .. . .. . Note : the IP address is used only to identify the client . I can use also a unique name . Something like a LAN chat between clients and server . I don t understand how edit the sample n . 31 to do it . This sample is based on interface . Comment : The link-to the framework should be synopse.info not .com .. . Answer : No need to store the IP or whatever low-level implementation parameter by the way the IP would not be able to identify a connection in an unique manner : several clients may share the same IP . In the mORMot framework asynchronous callbacks are implemented via interface parameters . On the server-side each instance of this parameter would be in fact a fake class instance linked to the input connection able to call back the client via its interface methods . This is a pretty straightforward way of implementing callbacks - in fact this is a good way of implementing SOLID callbacks on the server-side and the mORMot framework allows to publish this mechanism in a client-server way by using WebSockets . So you first define the callback interface and the service interface : .. . .. . Then on the server-side each call to IChatService.Join would subscribe to an internal list of connections : .. . .. . Then a remote call to the IChatService.BlaBla method should be broadcasted to all connected clients just by calling the IChatCallback.BlaBla method : .. . .. . Note that all the loop calls to IChatCallback.BlaBla would be made via WebSockets in an asynchronous and non blocking way so that even in case of huge number of clients the IChatService.BlaBla method won t block . In case of high numbers of messages the framework is even able to gather push-notification messages into a single message to reduce the resource use . The following method will be called by the server when a client callback instance is released either explicitly or if the connection is broken so could be used to unsubscribe to the notification : .. . .. . On the server-side you define the service as such : .. . .. . Here the optExecLockedPerInterface option has been set so that all method calls would be made thread-safe so that concurrent access to the internal fConnected list would be safe . On the client-side you implement the IChatCallback callback interface : .. . .. . Then you subscribe to your remote service as such : .. . .. . If you compare with existing client-server SOA solutions in Delphi Java C or even in Go or other frameworks this interface-based callback mechanism sounds pretty unique and easy to work with . Of course this work from Delphi 6 up to XE7 and also under Linux thanks to FPC or CrossKylix .

I wish to establish a connection and query the database directly via SQL without using the ORM Object-relational mapping features of mORMot .

Answer : In short : it is better to use the SynDB.pas layer over SynSQLite3.pas via its SynDBSQLite3.pas classes since it will allow your code to work in the future with any database accessible via OleDB ODBC or even direct access e.g . for Oracle . For instance using a variant for holding column data : .. . .. . So for your question read the SynDB-related part of the mORMot documentation and all the related blog articles http : blog.synopse.info tag SynDB . Those classes are used by the ORM but you can use those without the ORM . To start with there is a TQuery wrapper in SynDB.pas which works very well with SQLite3 and allow classic code-level programming . But there is not 100 RAD direct access with those units . Just some TClientDataSet fillers . This was not their purpose : they want fast and direct access to the DB in code not via the UI plumbing .

Answer : I just tested it with Delphi Seattle 10 and the ODBC driver from http : ftp.postgresql.org pub odbc versions msi psqlodbc 09 03 0400.zip - with no problem . Ensure your PostgreSQL server has been defined to run on the same port as expected by the source . Edit the 5433 value into 5432 if you used the default port-number .

We want to offer our customers the possibility having their databases in cloud hosted in our server .So clients are written in Delphi server is a http IOCP server written also in Delphi from mORMot framework for dbs we use Firebird embedded . Our customers let s say 200 can have 25-30 Firebird databases total 5000-6000 databases accessed by 4-5 user per each customer . This is not happening all at once . One user can work in one db other 2 users can work in another db but all the dbs should be available and online . So I can have 800-1000 users working at 700-900 dbs .

Practically can I call FDManager.AddConnectionDef . . while other pools are in use .. . Answer : AFAIK Firebird embedded does not have any connection . As its name states it is embedded within the same process so there is no connection pool needed . Connection pools are needed when several clients connect disconnect to the same DB over the network whereas here all is embedded and you would have direct access to the Firebird engine . As such you may : .. . .. . Define one connnection per Firebird embedded database .. . Protect your SOA code via a mutex aka critical section per DB . In fact mORMot s HTTP IOCP server would run the incoming requests from a thread pool so ensure that all DB access is safely made . Ensure you use at least Firebird 2.5 since the embedded version is told to be threadsafe only since revision 2.5 see the release notes http : www.firebirdsql.org en firebird-2-5-release-description . Instead of FireDAC consider using ZDBC Zeos in latest 7.2 7.3 branch which has nice features together with the native mORMot SynDB libraries http : synopse.info files html Synopse 20mORMot 20Framework 20SAD 201.18.html TITL 126 . Comment : Agree to disagree - connection pools are used to to facilitate acquiring a resource when normally creating establishing a new one will take time and or resources . Even attaching a local database file to the process like fbembed.dll does will take some time and resources - SQL privileges will be checked separate buffers will be allocated per every attachment even it s the same process and the same database file FB 2.5 . So connection-pooling apply here . Comment : Defining connections and protecting them with a critical section is not connection-pooling So why invent the wheel when there is available a tested one . Even if your scenario seems simple because it s only one connection per database I think I need at least two of them because sometimes one client can acquire the connection for a longer period of time because has to synchronize a bigger change log since it was last time online . Anyway your solution is good one because it has one critical section per db and Firedac will have one critical section per all databases .", "Question : I m in process of upgrading our client-server ERP app to multi-tier .

Practically can I call FDManager.AddConnectionDef . . while other pools are in use .. . Answer : Looking at Firedac sources seems that all about adding connection definitions and acquiring connections in pooled mode is thread-safe . Adding a connection definition or matching one is guarded by a TMultiReadExclusiveWriteSynchronizer and acquiring a connection from the pool is guarded by a TCriticalSection . So answers : .. . .. . 1 . I don t have to create all ConnectionDef s before server starts serving requests . 2 . Yes I can call safely FDManager.AddConnectionDef . . while other pools are in use . Using Firedac acquiring a connection for any of those databases will be guarded by one TCriticalSection . The solution proposed by @Arnaud Bouchez presents a more grained access by creating one TCriticalSection per database and I think will scale better but you should be aware of a bug when using multiple TCriticalSection especially that all will be initiated at once : .. . .. . https : www.delphitools.info 2011 11 30 fixing-tcriticalsection .. . .. . In that article present a very simple fix for this bug . Comment : Since you are using mORMot you can use the TSynLocker record or the IAutoLocker TAutoLocker interface class which fixes the TCriticalSection bug allows to protect a whole method in one call and uses the padding space to store some values which would be protected by the lock .

Answer : FireDAC is more helpful than some other frameworks in that when things go wrong the exception messages often say how to fix the problem . So in your case given that the message says you can drop component TFDPhysXXXDriverLink into your project the thing to try first would be to drop the relevant DriverLink component onto your form datamodule .

Thanks .. . Answer : The problem is that XML does not have distinction between concepts of Objects in JSON term that is collection of key-value pairs and Arrays ordered sequence of values without name . When using data-binding POJOs it is possible to determine from Java type which one a particular XML element means -- if Java property is a List or array it has to be Array otherwise Object -- but when only telling mapper to map XML to java.util.Map there is no such distinction and default handling will essentially consider all XML Elements to indicate Objects . And since Objects can not have properties with duplicate names only one of the values last one is retained . There is no simple way to avoid that using XmlMapper : you will need custom handling of some sort . Comment : I understand the reason for this issue but can you share some ideas on how to do this custom handling Do you know about any other Java library for XML to JSON conversion that can address this issue Comment : @Aman no I do not think it is possible to reliably convert from XML to JSON without having actual understanding of structure -- XML and JSON have different data models so you need to help with conversion . So better way in my opinion is to define actual Java classes to map XML content to and then serialize instances as JSON . This allows proper handling of list array values .

Any idea on how to solve the problem thanks Comment : Try removing JsonTypeInfo.As.WRAPPER OBJECT Comment : While not a direct solution I would recommend trying out more recent Jackson version 2.7.4 ideally since there have been a few fixes to XML handling since 2.4 .

Answer : There isn t a Wikidata equivalent to the Freebase Suggest Search or Topic APIs . They ve got a beta SPARQL endpoint that you could use to painfully roll your own replacement for Freebase Topic details below but if you don t have an immediate need to migrate you might consider waiting until the new promised Knowledge Graph equivalents are available . Google has promised a 3 month transition period after the availability of the new APIs before they shut down Freebase . But you need to decide how willing you are to trust them . The other advantage to delaying the transition is that it gives the Wikidata folks more time to get their act together and build some usable APIs . Of course you need to be able to live with the fact that Freebase is read-only . If you want to roll your own Wikidata query for Freebase IDs you can use the following query as a starting point : .. . .. . TinyURL to query editor http : tinyurl.com otdc78s .. . .. . You can get back JSON results by sending the query to the API endpoint with this base URL https : query.wikidata.org bigdata namespace wdq sparql format json query https : query.wikidata.org bigdata namespace wdq sparql format json query followed by your URL encoded query .. . .. .

Comment : June 30 2015 or three months after they release the new APIs which are now something like 6 months late whichever is later . Which reminds me the new APIs are another alternative .

Plus the freebase API will get shut down on 31st of August and I was hoping for an update on the KG API . .. . Answer : Google does not expose additional facts from its knowledge graph so you d have to get data from an outside source . To my knowledge there are no complete sources that are available . There are incomplete ones such as Wikidata DBPedia and loads of the Freebase dump data . Youtube has a Freebase Topic API https : developers.google.com youtube v3 guides searching by topic you can search for videos and channels by Knowledge Graph id .

Answer : As part of the Freebase retirement announcement https : plus.google.com 109936836907132434202 posts bu3z2wVqcQc Google said that they would be offering a couple of new Knowledge Graph APIs and that there would be a 3 month overlap between the availability of these new services and the shutdown of Freebase . Presumably Google services like YouTube which depend on Freebase MIDs will transition to these new services will transition to the new API perhaps with unchanged identifiers but not much is known concretely because a Google is overdue with the new APIs and b they haven t said anything else about the transition process . UPDATE : The Google Knowledge Graph Search API https : developers.google.com knowledge-graph became available in December 2015 and provides support for looking things up by KG ID which is the same as the old Freebase ID used by YouTube .", "Question : I have been using OpenRefine 2.6 Beta 1 w o problems since its release and later with the reconciliation service at : .. . .. . http : reconcile.freebaseapps.com reconcile .. . .. .

My question is how can I use those returned topics for things like getting all videos that are related to that topic which is offered as an example in the video as well considering that the Freebase API is not available at the moment and it will be shut down in the future For example for m 0410tth the Google Knowledge Graph doesn t return anything when making a request to : .. . .. .

I know that not all of the information from Freebase has been included into GK graph and I also know that there is a file for mappings between Freebase s MIDs and Wikidata s QIDs but they don t seem to help me right now . How should I make use of the topicIDs that YouTube offers me and how can I correlate them with other YouTube videos at the moment This question is not about how to use Freebase MIDs for Wikidata searching it s about the official Google response on how to make use of the relevantTopicIds that their API is offering since the documentation doesn t offer any insights into that . .. . Answer : I m not sure what your actual question is but the current situation is this : Freebase is deprecated but YouTube Data API v3 still references it and video s topicDetails part returns relevant topics in a form of Freebase identifiers . While I know of no consistent way of labeling those since Freebase has been shut down you can still use them to find relevant YouTube videos based on the identifiers alone . So for example : .. . .. . Which returns : .. . .. . I happen to know m 0qsc46 is the topicId for The Witcher 3 game I want other videos about that so I just use YouTube search method : .. . .. . Unfortunately AFAIK there is no way to build queries combining more than one topic . I expect some replacement for Freebase topicIds to appear in YTD API within a few months . Comment : Thanks for the response The question was mainly to have an official Google response on how could I use those topics now and in the future as well based on the fact that the Freebase API will be shut down as of 31st of Aug . Also in that YouTube video they state a future work including Taxonomies . Right now the topicDetails part doesn t include topicIds every time just relevantTopicIds and also almost all of those MIDs don t appear when searching on the knowledge graph . Comment : Unfortunately you re unlikely to get an official response .

Answer : Both Wikidata and Google Knowledge Graph do not contain all Freebase entries so its not clear if there will be a full replacement solution . Freebase includes many entries that Wikipedia does not for example it contains automatically created entries for a large corpus of creative works books songs TV shows etc its unlikely Wikidata would contain such data in the near future . Also Wikidata is importing entries from Freebase manually so it could be a very long time before all entries are matched with their corresponding Wikidata items . Like you found in my playing around with Google Knowledge Graph it appears to not include all Freebase entries either . It looks like it doesn t include some abstract concepts like m 0m1xv talk show . I haven t found this documented so its not clear to me whether this is intentional or perhaps a beta issue .", "Question : I hope this is the right place to ask this question .

Answer : Images have not been migrated . As a matter of fact almost no Freebase data has been migrated to Wikidata but that s a different story . Some Wikidata items do have Freebase IDs and some also have links to images in Wikimedia Commons so the intersection of these two sets may give you a relatively straightforward path forward .

Answer : I ve used the Prismatic Interest graph API https : github.com Prismatic interest-graph for somewhat similar functionality .

Are there any better methods to query this The best I could come up with is using the Wikidata API search entities endpoint https : www.wikidata.org w api.php action wbsearchentities with the element name then filter the desired results in Sparql query to minimize the domain of the query instead of the whole graph . 2 . I m a little worried about using this method in a production environment since Wikidata Sparql is in Beta . Any best practices for migrating knowledge graph use cases from freebase Is there any update regarding the migration of data from Freebase to Wikidata Finally are there any other mature alternatives to the deprecated Freebase service Comment : In a production environment use your own SPARQL endpoint and load the Wikidata into it . Anything else doesn t make sense as do not have any control over it s availability . Comment : Isn t there an external production service alternative Maintaining an in-house wikidata mirror also doesn t make sense for the extent I need from the service . Comment : What means external production Indeed you can use the public SPARQL endpoint but it s hosted for free and you do not pay anything for what you get . Thus you can not give rise to any claims . Hosting such a service costs money and you know that you re not the only one using it . In addition you can t make it faster as you have to rely on the hardware that they use for hosting the service . Comment : I mean a paid alternative . Will Google Knowledge Graph be better in terms of reliability and the extend of the data Is there any other suggestion Comment : This is a bit of a plug so therefore not an answer but perhaps a cloud service like Ontotext S4 http : s4.ontotext.com would fit your need . They offer cloud instances of GraphDB as well as access to hosted versions of various open datasets . Not sure Wikidata is in there but if it s not I m sure you can ask them about it . .. . Answer : What endpoint are you querying against Querying against a shared public endpoint with no SLA beta or not for a production service is very risky proposition . Wikidata offers full database dumps that you can tailor subset and load into whatever infrastructure you like . That would give you complete control over performance quality and any other metrics which are important to you . As far as migrating from Freebase goes there is no migration path . The track that train was on has come to an end at least for external non-Google users . It s not just deprecated it was shut down completely a while ago . A tiny fraction of the data was imported to Wikidata and they shared a bunch in common already due to their common ancestor Wikipedia but none of the programmatic features such as MQL s JSON query-by-example Freebase Search Freebase Suggest Google-scale performance or availability etc is available yet for Wikidata . If the data is important to you you should self-host using whatever infrastructure meets your needs . Comment : I m using query.wikidata.org sparql https : query.wikidata.org sparql endpoint .

Comment : Are you compiling the library from source or trying to link-to a compiled library you ve downloaded .. . Answer : Here is how I ve built libjpeg using MinGW on Windows : .. . .. . 1 . Get MinGW with MSYS .. . .. . I ve got a copy from http : sourceforge.net projects mingw . Quoting from www.mingw.org : .. . .. . MSYS is a collection of GNU utilities such as bash make gawk and grep to allow building of applications and programs which depend on traditionally UNIX tools to be present . We will need it to run the configure script that comes with libjpeg sources . 2 . Get libjpeg sources .. . .. . From http : www.ijg.org take the Unix format package the Windows one won t work with this procedure . I took the jpeg 8d version . 3 . Prepare a building directory .. . .. . I ve made a temporary directory named tmp in D : but you could choose whatever suits your needs . The thing that matters is the name of paths in MSYS . As it brings some Unixity to Windows paths cannot be used in their original form . In a nutshell : .. . .. . C : path to file becomes c path to file in MSYS land an so D : tmp becomes d tmp . Decompress the libjpeg sources in D : tmp so you have a jpeg-8d directory in there . Create a jpeg-build directory inside D : tmp it will hold the built library . Now everything is ready for the build . 4 . . configure make make install .. . .. . That is the mantra of building in Unix land . An option should be added to redirect the install process to D : tmp jpeg-build . Run the following commands in an MSYS shell also named MinGW shell in Windows start menu : .. . .. . As an additional step you can run make test for safety . These commands will build both static and shared versions of libjpeg . 5 . Take the goods delete the temporaries .. . .. . If everything runs fine you can delete the D : tmp jpeg-8d directory but keep the jpeg-build one . It contains : .. . .. . an include directory containing libjpeg headers . You can move them to your compiler s headers directory . a lib directory with .a file to pass to the linker . You can move them to your compiler s library directory . a bin directory holding the libjpeg shared library libjpeg-8.dll and jpeg tools . a share directory containing man pages for the jpeg tools . You can now build your program and link it against libjpeg by indicating the right include and library paths . You can find many details about the libjpeg building and installation process in install.txt inside the source package . I hope this will be useful . Comment : I installed the MinGW but I can t find any executable . Comment : And it says configure - command not found . Comment : What executable are you looking for You should switch to the jpeg-8d directory before running commands : cd d tmp jpeg-8d . I ll update my answer . Comment : I did everything as you said i configured Dev C++ by coping all the headers and other files now I should by able to run the example.c included in libjpeg downloaded archive Comment : I haven t used the example.c provided in libjpeg sources but nothing prevent it from working . I ve used libjpeg in the past in a little game-engine and it worked like a charm .", "Question : Using libjpeg or libjpeg-turbo to do JPEG encoding I was wondering if there is any improvements providing multiple scanlines at once to the jpeg write scanlines function . I did some tests on 720x288 images but I only get 0 5 increase when processing the whole image at once . I guess this increase is just due to the removal of call stack overhead but I was expecting a bit more at least with libjpeg-turbo . The performance test was run with Callgrind in Valgrind so maybe I m missing something . Or I really misunderstood how JPEG encoder works . .. . Answer : JPEG has a minimum height of a row called MCU height . It is 8 lines in images without subsampling 4 : 4 : 4 mode or 16 lines if chroma is subsampled 4 : 2 : 0 mode . If you feed libjpeg these 8 or 16 lines it will be able to process the whole row in one go . Otherwise it ll need to do extra bookkeeping or buffering . Writing multiple MCU heights at a time or the whole image won t hurt . Comment : Nice clue . Do you have any reference for that Is that your experience Or should I just test it by myself in my own setup Comment : JPEG has a concept of MCU minimum coding unit which is a block or 4x4 luma blocks when subsampling and libjpeg is built around processing rows of MCUs .", "Question : I am using the C++ JPEG library libjpeg and I have realized that when some functions fail exit is called and the application is closed . How can I override this behavior and prevent the application from closing on libjpeg errors .. . Answer : This is the default behavior of libjpeg .

Could anyone describe which standards of JPEG are supported by the library Furthermore how to set parameters for compression to be compatible with DICOM JPEG Lossless standard Comment : It appears that libjpeg supports the lossless mode JPEG-LS which is different from the lossless JPEG you re working with . I haven t seen any implementations of this codec except in DICOM libraries . I wrote my own and it s actually very simplistic . Comment : Are you sure libjpeg supports JPEG-LS I think it s later modification of JPEG and libjpeg - as far as i know - supports the basic one Comment : I m not 100 sure but I didn t see anything that looked like it would help you . The truth is that to decode the DICOM lossless JPEG requires about 100 lines of C code for the specific lossless algorithm . It s similar to PNG with a filter method and delta values encoded with max-length 16 Huffman codes . Comment : Could you please tell me what were you relying on writing your own decompressor If it is simple i would do it on my own rather than investigate how to use specific libraries to do it for me : .. .

You ll discover that there is no mention to your boolean lossless . libjpeg 6b is the reference codebase that served two forks : .. . .. . Guido Vollbeding IJG maintainer : libjpeg 7 and up with the famous SmartScale extension .. . dcommander libjpeg-turbo in particular reads the comments from here https : github.com libjpeg-turbo libjpeg-turbo libjpeg-v7-and-v8-apiabi-emulation . So if this is the libjpeg you were talking about then yes it does not support the lossless mode specified in the standard . The lossless patch was created by Ken Murchison and you should still be able to find it eg . here https : groups.google.com forum msg comp.protocols.dicom rrkP8BxoMRk Ij4dfprggp8J . It should apply directly over libjpeg 6b . If you do not want to patch the lib yourself have a quick look at GDCM http : gdcm.sourceforge.net and or DCMTK http : dcmtk.org since they are both using a convenient copy of libjpeg + the famous lossless patch with some further patch thanks to DCMTK team . At this point this should answer your question . For further details on libjpeg IJG and libjpeg-turbo informations I suggest you read informations from : .. . .. . https : bugs.debian.org cgi-bin bugreport.cgi bug 612341 131 .. . https : lists.debian.org debian-devel-announce 2014 08 msg00000.html .. . .. . .. . .. . In case you are still reading I sugest you also have a quick look at another library purposely also called libjpeg see it here at github https : github.com thorfdbg libjpeg . In particular go over the README file here https : github.com thorfdbg libjpeg blob master README . And you ll discover that this libjpeg is a full implementation of ITU 81 lossy lossless 8 12 16bits and even hierarchical all in one single code without the need to do multiple compilations . And for completeness I found that the following links were very usefull : .. . .. . http : fileformats.archiveteam.org wiki Lossless JPEG original .. . https : sourceforge.net projects jpeg Comment : Thank you you clarified it very well :", "Question : I am using the C++ JPEG library libjpeg and I have realized that when some functions fail exit is called and the application is closed .

Is there a way to get libjpeg to respect the orientation of the JPEG during decompression or will I have to parse out this orientation tag and manually rotate the image .. . Answer : the transupp.h header in libjpeg defines an API for lossless rotation . Included is also jpegtran.c source code for an executable that serves as an example . Comment : jpegtran appears to be able to rotate images losslessly but doesn t provide built-in EXIF detection - nor is it a library that I can call from within my code . Comment : the jpegtran source code is included in libjpeg version 8d and serves as an example of how to apply lossless transformation using libjpeg Comment : Very helpful . That plus the EXIF parsing code from jhead http : www.sentex.net mwandel jhead should do the trick .", "Question : The project https : github.com iiordanov bVNC using gstreamer sdk http : docs.gstreamer.com display GstSDK Installing+for+Android+development . the jpeg library used by it is jpeglib .

Great but are there some solid examples of using this API available Just looking to decompress a fairly vanilla jpeg in memory .

Answer : I refrained from responding because it has been a long time since I have prowled around in the LIBJPEG code and I understand that it has been rewritten .

I am really out of ideas why are DCTs after saving image to photo library altered . .. . Answer : iOS will always recompress your JPEG when you use UIImage and its methods hence altering DCT .

Answer : Using jpeg mem src works for me with libjpeg-turbo :", "Question : I m trying to load part of big JPEG file hundreds of megapixels with a limited memory-footprint . I need only about a 1000 scanlines of 20000 . It seems that current implementation of libjpeg as well as its fork libjpeg-turbo doesn t provide a way to skip unneeded 19k scanlines without decoding them . Is there a workaround for it without digging into libjpeg internals .. . Answer : You can t avoid having to decode the scan lines you want to skip but you can avoid storing them anywhere . When you get the callback from libjpeg for each row just wait until the row-number matches the section of scanlines you want . Comment : Why can t I do that AFAIU JPEG is stored in 8x8 blocks thus if I need only 1000 bottom scanlines I can skip top blocks 19k 8 and decode only ones I need . Do I miss something Let s not consider progressive compression atm Comment : It s been a long time since I ve had to work with the JPEG internals but isn t the Huffmann compression applied after the DCT transform on the 8x8 blocks That means the top blocks are a variable amount of data so you don t know how much to skip without at least doing the Huffmann decoding . I suppose you could do that and avoid doing the DCT reconstruction but as you say that would land you deep in the libjpeg internals ." ] }

If you have not already look at the AppDelegate in RevealControllerExample and try do the following .. . .. . 1 . Create an instance of your tabbar .. . 2 . Create SWRevealViewController init with nil as the rear and your tabbar as the front if you can t use nil as the rear just create a UIViewController but you won t use it . 3 .

Comment : My problem is when I choose in my menu and open it . It open without TabBar bottom . Comment : You menu viewcontroller needs to have a tab bar If so then just assign tab bar to the rightViewController . Do you need every option in the menu to load a tab bar Comment : Menu does not need tab bar . Others options viewcontroller or tableviewcontroller in the menu must load a tab bar bottom . Comment : I solved a problem by changing the tableviewcontroller to viewcontroller and manually adding the tab bar controller but I have lot controllers in my project .

I would like to do two things with these views : .. . .. . 1 . To open the Rear menu view from all of them .. . 2 . To be able to navigate back the stack using Unwind segues . I found out that if I push view controllers on top of each other using regular push segues then the unwind segue works as expected but then the self.revealViewController on each view controller is not set and the Menu can t be called using the revealToggle : selector . If I change the push segues to subclasses of SWRevealViewControllerSeguePushController then the views are pushed on top of each other and the Menu can be called from any of them using the revealToggle . Unfortunately the unwind segues stop working I think this might be because the view controllers are stacked using addChild instead of pushViewController on the SWRevealViewController class . Is there a way of working together with SWRevealViewController and Unwind Segues Below there is an example storyboard : .. . .. . SWRevealViewController and Unwind segue http : i.stack.imgur.com M3zrQ.png .. . .. . The first view controller is the navigation controller the second is the SWRevealViewController the three view controllers below navigate one to each other and the third has an unwind segue to the first . The first and third controllers have buttons that open the menu . As I stated before if the segues between the bottom view controllers are regular push segues then the unwind segue works as expected the menu button from the first view controller works as it is connected directly to the SWRevealViewController but the menu button from the third view controller doesn t . Switching the segue types to SWRevealViewControllerSeguePushController makes the menu buttons from the first and third view controllers work correctly but the unwind segue stops working . Oh and I tested using popToRootViewControllerAnimated : and it also doesn t work if the segues are set to SWRevealViewControllerSeguePushController .

Unfortunately the video didn t show exactly what I needed which was a view controller performing segues while being pushed by a SWRevealViewController . However Patrick Bodet at the SWRevealViewController git project helped me out and I will next post the answer he gave me . .. . Answer : I posted this question on SWRevealViewControllers github site https : github.com John-Lluch SWRevealViewController issues 543 issuecomment-176740682 and received an answer from Patrick Bodet who was EXTREMELY helpful . I will post the answer below so it may help somebody in the same situation as I . .. . .. . I had to update the storyboard and added an additional navigation controller as shown below . enter image description here http : i.stack.imgur.com mdGzU.png .. . .. . As shown in the figure I wanted to be able to push view controllers on top of each other and also to unwind the segues both to the Login screen from the Menu and from stacked view controllers . On my previous attempts it seemed as-if SWRevealViewController wasn t able to cope with proper navigation segues . Patrick s first suggestion was to move the original navigation controller from before the RevealViewController to before the First view controller . That actually worked by I still needed to be able to unwind segue from the Menu to the Login screen so I needed an additional navigation controller . As suggested by Patrick I added an additional Navigation Controller . And embarrassingly at the end I realised the button that pointed from the third to the first view controller had both an ibaction and a segue to the first so that was why it was acting all weird : - .. . .. . So for the storyboard shown above in order to work you just use regular Push segues for the view controllers . No need to use SWRevealViewControllerSeguePushController segues .

Answer : Update - changing my pseudo-comment to a real answer . I think this answer http : unix.stackexchange.com questions 17732 where-has-the-trailing-newline-char-gone-from-my-command-substitution should explain the behavior you are seeing . Specifically command substitution operators and backticks will strip trailing newlines from the command output . However the direct assignment in your second example doesn t do any command subsitution so works as expected . So I m afraid to say I think the upvoted comment you refer to is incorrect . .. . .. . I think the safest way to restore IFS is to set it in a subshell . All you need to do is put the relevant commands in parentheses : .. . .. . Of course invoking a subshell incurs a small delay so performance needs to be considered if this is to be repeated many times . .. . .. .

Answer : This is POSIX http : pubs.opengroup.org onlinepubs 9699919799 utilities read.html behaviour .

I m aware that changing the internal field separator IFS changes what the bash script iterates over . So why is it that the length of the array doesn t change Here s my example : .. . .. .

How do I do this Setting the IFS doesn t seem to do anything . I must be doing this wrong... . Thank you . .. . Answer : Bash arrays are in fact arrays . They are not strings which are parsed on demand . Once you create an array the elements are whatever they are and they won t change retroactively . However nothing in your example creates an array . If you wanted to create an array out of argument 2 you would need to use a different syntax : .. . .. . Although your strings to find is not an array bash allows you to refer to it as though it were an array of one element . So strings to find @ will always be one regardless of the contents of strings to find . Also your line : .. . .. . is really no different from .. . .. . Since that expansion is not quoted it will be word-split using the current value of IFS . If you use an array most of the time you will not want to write for string in strings to find @ because that just reassembles the elements of an array into a string and then word-splits them again which loses the original array structure . Normally you will avoid the word-splitting by using double quotes : .. . .. . As for your second question the value of IFS does not alter the shell grammar . Regardless of the value of IFS words in a command are separated by unquoted whitespace . After the line is parsed the shell performs parameter and other expansions on each word . As mentioned above if the expansion is not quoted the expanded text is then word-split using the value of IFS . If the word does not contain any expansions no word-splitting is performed . And even if the word does contain expansions word-splitting is only performed on the expansion itself . So if you write : .. . .. . my function will be called with a single argument no expansion takes places so no word-splitting occurs . However if you use 1 unquoted inside the function the expansion of 1 will be word-split if it is expanded in a context in which word-splitting occurs . On the other hand .. . .. . will cause my function to be invoked with three arguments . And finally .. . .. . is exactly the same as the first invocation because there is no : in the expansion .", "Question : In Shell script I want to achieve something like below : .. . .. .

Another confusing behavior can be found in 4.2 which is already fixed in 4.3 . By doing IFS cat foo foo expands well as 111 222 333 not affected by IFS as shown by cat which is 111 222 333 . However when we do IFS read bar foo echo bar the output would be 111 222 333 and would appear as-if foo expanded as 111 222 333 . This inconsistent behavior is no longer happening in Bash 4.3 and Bash 4.3 s behavior is probably a fix .

Here is my understanding of the behavior : .. . .. . X and X @ both expand to a b .. . X expands to a b .. . X @ expands to a b .. . and @ have the same behavior as X and X @ except for their content being the parameters of the program or function .. . .. . This seems to be confirmed by the bash manual http : www.gnu.org software bash manual bashref.html Arrays . In the line log1 X I therefore expect the quoted expression to expand to a b then to be passed to the log1 function . The function has a single string parameter which it displays . Why does something else happen It d be cool if your answers were backed by manual standard references .. . Answer : In the POSIX spec section on Special Parameters http : pubs.opengroup.org onlinepubs 9699919799 utilities V3 chap02.html tag 18 05 02 we find . @ .. . .. . Expands to the positional parameters starting from one . When the expansion occurs within double-quotes and where field splitting see Field Splitting is performed each positional parameter shall expand as a separate field with the provision that the expansion of the first parameter shall still be joined with the beginning part of the original word assuming that the expanded parameter was embedded within a word and the expansion of the last parameter shall still be joined with the last part of the original word . If there are no positional parameters the expansion of @ shall generate zero fields even when @ is double-quoted . .. . .. . .. . Expands to the positional parameters starting from one . When the expansion occurs within a double-quoted string see Double-Quotes it shall expand to a single field with the value of each parameter separated by the first character of the IFS variable or by a if IFS is unset . If IFS is set to a null string this is not equivalent to unsetting it its first character does not exist so the parameter values are concatenated . So starting with the quoted variants they are simpler : .. . .. . We see that the expansion expand s to a single field with the value of each parameter separated by the first character of the IFS variable . This is why you get a b from echo X and log2 X . We also see that the @ expansion expands such that each positional parameter shall expand as a separate field . This is why you get a b from echo X @ and log2 X @ . Did you see that note about field splitting in the spec text where field splitting see Field Splitting is performed That s the key to the mystery here . Outside of quotes the behavior of the expansions is the same . The difference is what happens after that . Specifically field word splitting . The simplest way to show the problem is to run your code with set -x enabled . Which gets you this : .. . .. . The thing to notice here is that by the time log1 is called in all but the final case the is already gone . The reason it is already gone is because without quotes the results of the variable expansion in this case the expansion are field word split . And since IFS is used both to combine the fields being expanded and then to split them again the gets swallowed by field splitting . And to finish the explanation for the case actually in question the reason this fails for log1 even with the quoted version of the expansion in the call i.e . log1 X which expands to log1 a b correctly is because log1 itself does not use a quoted expansion of @ so the expansion of @ in the function is itself word-split as can be seen by echo a b in that log1 case as well as all the other log1 cases .", "Question : Being new to shell scripting I am not clear about the Quoting and splitting concepts in bash .

In your case it will act same as IFS n Comment : It s a simple question You could ask this to the previous question answerer @Chepner . Comment : @anubhava Thanks . So if IFS is null then it s the same as newline .. . Answer : IFS does many things but you are asking about that particular loop . The effect in that loop is to preserve leading and trailing white space in line . To illustrate first observe with IFS set to nothing : .. . .. . The line variable contains all the white space it received on its stdin . Now consider the same statement with the default IFS : .. . .. . In this version the white space internal to the line is still preserved . But the leading and trailing white space have been removed . What does -r do in read -r The -r option prevents read from treating backslash as a special character . To illustrate we use two echo commands that supply two lines to the while-loop . Observe what happens with -r : .. . .. . Now observe what happens without -r : .. . .. . Without -r two changes happened . First the double-backslash was converted to a single backslash . Second the backslash on the end of the first line was interpreted as a line-continuation character and the two lines were merged into one . In sum if you want backslashes in the input to have special meaning don t use -r . If you want backslashes in the input to be taken as plain characters then use -r . Multiple lines of input .. . .. . Since read takes input one line at a time IFS behaves affects each line of multiple line input in the same way that it affects single line input . -r behaves similarly with the exception that without -r multiple lines can be combined into one line using the trailing backslash as shown above . The behavior with multiple line input however can be changed drastically using read s -d flag . -d changes the delimiter character that read uses to mark the end of an input line . For example we can terminate lines with a tab character : .. . .. . Here the .. . construct was used to enter special-characters like newline n and tab t . Observe that with -d t read divides its input into lines based on tab characters . Anything after the final tab is ignored . How to handle the most difficult file names .. . .. . The most important use of the features described above is to process difficult file names . Since the one character that cannot appear in path filenames is the null character the null character can be used to separate a list of file names . As an example : Comment : +1 nice explanation . What s the meaning of -r Comment : @AvinashRaj Thanks . For -r see updated answer . Comment : Excellent explanation .

The same happens when I try to enter this code into my terminal : .. . .. . alt text http : roundcan.narod.ru some pics 21.jpg .. . .. . I think I miss out on some basics here . Perhaps I need to create a file that would contain that code and then run that file somehow but I really don t know where I need to create that file and with what extensdion . Can anyone please help me with this .. . Answer : You need to run those commands inside twill shell instead of python shell .. . .. . You can put twill commands when you see .. . .. . or there is 2 only lines in twill-sh file .. . .. . you can just copy-paste that 2 lines to python prompt . Comment : Hello S.Mark Do you know where that twill shell could be located There is one file called twill-sh in my twill-0.9 folder . Is that the twill shell Strange it s blank - I mean it has no extension . Comment : Hi yeah run like python twill-sh Comment : @brilliant I have updated my answer .

Comment : You re welcome brilliant : -", "Question : I am sorry I have already asked this question on Superuser but nobody answers there so I deleted it from Superuser and decided to post it here . Hope it s not a big crime especially given the fact that I was firstly advised to use twill here on StackOverflow not on SuperUser .. . .. . How do I start using twill I have just downloaded it unpacked it and clicked on the setup .py file in the folder . The black window terminal appeared for a moment and vanished . I do have Python 2.5 installed on my computer - along with SDK from Google App Engine .. . .. . In the twill documentation section http : twill.idyll.org it says : .. . .. . .. . .. . Downloading twill .. . .. . The latest release of twill is twill 0.9 released Thursday December 27th 2007 it is available for download at http : darcs.idyll.org t projects twill-0.9.tar.gz .

Can anyone please help me out here Thank You in advance . .. . .. . Update 1 : .. . .. . This update is a response to the answer given by S.Mark .. . .. . Hello S.Mark I ve tried to follow Your instructions . Here is what happened : .. . .. . Firstly I created a folder on my D disk and named it tmp . Then I downloaded and extracted twill-0.9 into that folder . So now the path to this file on my computer was just as same as the one in Your example : D : tmp twill-0.9 : alt text http : roundcan.narod.ru some pics 01 path big.jpg .. . .. . alt text http : roundcan.narod.ru some pics 02 path small.jpg .. . .. . Then I tried to open the command-prompt on my computer : alt text http : roundcan.narod.ru some pics 03 window.jpg .. . .. . alt text http : roundcan.narod.ru some pics 04 prompt big.jpg .. . .. . alt text http : roundcan.narod.ru some pics 05 prompt small.jpg .. . .. . alt text http : roundcan.narod.ru some pics 06 admin.jpg .. . .. . alt text http : roundcan.narod.ru some pics 07 admin big.jpg .. . .. . Then following step 2 of Your instructions I tried to switch to D disk : .. . .. . alt text http : roundcan.narod.ru some pics 08 switch try.jpg .. . .. . But for some reason it didn t work : .. . .. . alt text http : roundcan.narod.ru some pics 09 switch result.jpg .. . .. . This Chinese line says something like This action has been rejected . Why is it so Well I tried to proceed to step 3 anyway and here is what I ve got : .. . .. . alt text http : roundcan.narod.ru some pics 10 third step.jpg .. . .. . As far as I can understand this Chinese line says something like C : is neither internal nor external command thus it cannot be carried out . Why is it so Is there something wrong with my computer .. . .. . Update 2 : .. . .. . This update is my second response to the answer given by S.Mark .. . .. . Hello S.Mark Thank You for Your answer again . Yes this time it worked when I just typed those parts that You highlighted in Your post . So when I typed just d : in the very beginning it worked But then when I typed python setup.py build I got the same error message python is neither an internal or external command it can t be carried out . : alt text http : roundcan.narod.ru some pics 12.jpg .. . .. . I tried to repeat this command and accidentally omitted the word python : .. . alt text http : roundcan.narod.ru some pics 13.jpg When I pressed Enter key the build-process seemed to launch - at least what I saw then resembled the step 4 of Your instructions start the build-process very much : alt text http : roundcan.narod.ru some pics 14.jpg alt text http : roundcan.narod.ru some pics 15.jpg alt text http : roundcan.narod.ru some pics 16.jpg But now I am a little bit hesitant about proceeding to step 5 Install It as I am not sure if what I have done is the right thing . If what I did in step 4 was okay should I also omit the word python in step 5 A side question : How did You manage to put the contents of the terminal into Your post without making screenshots Is it like there is some way of putting the terminal s contents into the clipboard Making screenshots all the time and hosting them prior to posting is quite cumbersome . .. . .. . Update 3 : .. . .. . This update is my third response to S.Mark .. . .. . S.Mark hello again Hope you are not sick and tired of me yet .. . .. . and yeah you could omit python and directly run setup.py because your python installation registered .py in registry regarding step 5 you could just run setup.py install I followed these words of Yours and install process ran successfully Thank You . But as for the following steps then open python prompt from start menu and test step 6 and 8 there wasn t much success in the Python prompt : alt text http : roundcan.narod.ru some pics 17.jpg .. . .. . Neither was it successful in the usual command-prompt terminal : alt text http : roundcan.narod.ru some pics 18.jpg .. . .. . It again says in Chinese that python is neither an internal nor external command and therefore can t be carried out . Do You have any idea why it didn t work where is your python installation C : Python25 - Yes that s right . there is a setting command-prompt properties - easy edit mode to enable selection of text on the command-prompt could you ask that in superuser.com - Sure I will ask this question there . Thanks for telling me . Comment : What platform are you on Comment : ah you don t need to type C : thats is my prompt like C : Documents and Settings Administrator in yours just type D : etc. . I am going to update my post to highlight those parts . Comment : @brilliant for your second update its becuause of python.exe not on your path where is your python installation C : Python25 if so type set PATH C : Python25 PATH and lt enter before you type python setup.py build and yeah you could omit python and directly run setup.py because your python installation registered .py in registry . Comment : regarding copying terminal texts there is a setting command-prompt properties - easy edit mode to enable selection of text on the command-prompt could you ask that in superuser.com Comment : regarding step 5 you could just run setup.py install then open python prompt from start menu and test step 6 and 8 .. . Answer : You cannot just double click setup.py .. . .. . You need to open command-prompt or shell and go to that folder .. . .. . and need to do .. . .. . install step should automatically do build normally so only last one will work .. . .. . .. . .. . Edit : ok here is superuser way of installation steps .. . .. . 1 . I have extracted twill-0.9.tar.gz to D : tmp twill-0.9 .. . .. . 2 . I am on drive C so I switched to D : .. . .. .

Answer : I believe you re looking for a way to import the twill module into App-Engine . You ll have to figure out either where the twill python files are or how to get a source package of them to package it with your website but it looks like importing 3rd party modules can be done with a few exceptions see below . Try ZipImport http : docs.python.org library zipimport.html following the directions from Google s site here http : code.google.com appengine docs python tools libraries.html zipimport and here http : code.google.com appengine articles django10 zipimport.html . from Google s third Party Library page : .. . .. . App Engine uses a custom version of the zipimport feature instead of the standard implementation . It generally works the usual way : add the Zip archive to sys.path then import as usual . With these exceptions : zipimport can only import modules stored in the archive as .py source files . It cannot import modules stored as .pyc or .pyo files . zipimport is implemented in pure Python and does not use native-code for decompression C code . Comment : Thank You winfred for this input .

Answer : To use third-party libraries in App Engine projects you simply have to include them with your application when you deploy . Copy the twill folder the one containing init .py into your application s folder and deploy it . Looking at the twill Google Code project it appears that twill includes its dependencies pyparsing mechanize etc . in the package so you may not need to include anything else .

What is the reason I am getting this error which I think has to do with the security of the itunes page And how would I log into the given page via command-line Comment : I m not familiar with this tool but it looks like Twill uses Mechanize http : wwwsearch.sourceforge.net mechanize . You should be able to install this using Python s usual easy install http : pypi.python.org pypi setuptools mechanism . Comment : twill uses its own mechanize and some other packages . And for that it adds them to sys.path . The problem is related to this surely but this does not yet give clues . Comment : Twill package documentation mentions problems with mechanize in its doc problems.html at the very end as of version 0.9 . .. . Answer : I believe python-mechanize Ubuntu name for it may vary for other systems and maybe some other dependencies are somehow not installed or removed on your system . While twill distro provides its own mechanize distros usually make sure to do it right . Before resorting to sudo easy install consider finding and installing packages by using your distro s way .

Does that do what you need to do twill.idyll.org commands.html http : twill.idyll.org commands.html Comment : Sadly the tumblr s photo upload isn t working that way as I found : I checked the forms at the tumblr.com new photo page and there isn t any form-for files .", "Question : I ve been trying to learn Twill Scripting on Python and I am using Python 3.4 and Twill 1.8.0 . Been reading some posts here and I found it interesting to study . But I do have a problem installing Twill . I just knew that PRINT in Python is now a function so meaning it needs parenthesis and that s where my problem starts . As I look through the codes on Twill 1.8.0 I think it isn t oriented with the change of using PRINT yet . Strings are not enclosed with parenthesis so I was thinking maybe there is a new patch or version of Twill that adapts the changes of Python is there any or is there anything I can do about this aside from manually editing Twill files Your response is highly appreciated . Comment : I think it s a legitimate question whether Twill is available for Python3 . Upvoted to cancel out the malicious downvote . .. . Answer : I just found the answer . Thanks for viewing this question and probably for that downvote SAD FACE . . So the solution that I found was to use the 2to3 Script Tool found in Python Folder .

Answer : This helped partially solve my issue but other problems cropped up later particularly in filling forms submitting them and migrating further in the website . tidy is disabled in this way tidy does not play well with the google sandbox and I am able to show the webpage via self.response.write show . As a side note : be careful about using TextEdit to edit .py files when working with google-app-engine . I was getting all sorts of weird non-ascii character errors . I added - - coding : utf-8 - - to the first line of the python file which sort-of helped and switched to using pycharm s ide which really helped . twill is giving me all sorts of issues inside google-app-engine s sandbox that i am not getting on my system . i can get finally the html for one webpage but can t submit forms in the way i was doing so simply on my system . showforms isn t even showing the forms maybe because i disabled tidy and the html is not being parsed properly i think one way to move forward here is to get tidy to work inside twill . obviously roadblocks are being hit under the hood and they are hard for me to see . it seems like twill is a high level abstraction and maybe is not a good idea right now for using on google-app-engine . next i will try to switch to mechanize.py or look for another sandbox maybe amazon", "Question : I m currently using urllib2 and BeautifulSoup to open and parse html data .

I m having some trouble getting this to work though and can t seem to find any documentation or examples on how to use regular expressions with Twill . Any help or advice on how to do this or solve this problem in general would be much appreciated . .. . Answer : I d rather user CSS selectors or real regexps on page source .

Following the overlay documentation developers.google.com chart interactive docs overlays overview https : developers.google.com chart interactive docs overlays overview you d need to position the styling information before the chart script generated by googleVis and body information after .

Your solution seems to work for Google Charts itself but not for googlevis or I m doing it wrong . Comment : that is the JavaScript JSON syntax for an object with properties -- not sure if there is a way to define in googlevis .. . Answer : After talking to one of the developers of the googleVis package I got the solution to the problem now . The formatted value contains extra speak marks which have to be removed before the text is usable as HTML .

Answer : There are many ways to proceed with this with unpredictable results . Some of the tricks : .. . .. . 1 . Xvfb imagemagick and browser . You need to have all three of them installed . This won t work on Windows . I am assuming you have install xvfb and imagemagick . You start xvfb server in shell : - .. . .. . Xvfb : 3 -screen 0 1024x768x24 .. . .. . .. . Now in R you can print the file as html : .. . .. . print p file p.html .. . .. . .. . Now a system call : .. . .. . system DISPLAY : 3 firefox g1.html .. . .. . .. . Now print the file using : .. . .. . system DISPLAY : 3 import -window root p.png .. . .. . .. . You will get the file as p.png . You can use some other browser also like chrome . 2 . Using wkhtmltopdf package . After installing wkhtmltopdf and having it in your PATH use system call : .. . .. . print p file p.html .. . system wkhtmltoimage --enable-plugins --javascript-delay 10000 p.html p.png .. . .. . .. . Results aren t predictable . Sometime flash doesn t work . Sometime it works for some platform . I couldn t reproduce like my first solution . For OP this solution worked . This is a cross-platform solution . 3 . As shiny app phantomjs and webshot : .. . .. . Assuming you have printed the file that I have given create a shiny app using following methods : .. . .. . mkdir app Create App Directory .. . Create UI .. . cat - EOF app ui.R .. . library shiny .. . .. . shinyUI fluidPage .. . titlePanel Google Chart .. . mainPanel .. . includeHTML . . g1.html .. . .. . .. . EOF .. . Create server .. . cat - EOF app server.R .. . library shiny .. . shinyServer function input output .. . .. . EOF .. . .. . .. . Now install phantomjs : .. . .. . npm-install -g phantomjs .. . .. . .. . In r : - .. . .. . install.packages webshot .. . appshot app p.png .. . .. . .. . You will see that you won t get flash charts because phantomjs now doesn t support flash . So this method too is limited . Only first method will work but it s not cross-platform . But you can proceed with that approach in windows by using equivalent stuff . Comment : Thanks I was of course hoping there was a more straight forward way but I will accept this as the answer if nothing new pops up in the next week . So far I have just opened the plot in my browser and printed to pdf . That works too and is perhaps the fastest for a limited number of plots .

NOTE : I can t simply erase the content from the source List as it would be obvious because COL 2 in my real case is a Boolean represented as checkbox . .. . Answer : There are many ways how you can implement the requirement . One of the most easy is the setting of color : transparent CSS on the cells which you need to hide . For example you define the CSS rule .. . .. . and you assign the class hiddenCell to specified cells of the COL 2 . You can use cellattr property of COL 2 for it : .. . .. . The demo http : www.ok-soft-gmbh.com jqGrid transparentTextInColumn.htm demonstrates the approach . Disadvantage of the approach - the hidden text still exist on HTML page and so one can examine it if required . Another way is the usage of custom formatters . For example you can define the following formatter callback .. . .. . The demo http : www.ok-soft-gmbh.com jqGrid removeTextInColumn.htm demonstrates the second approach . Disadvantage of the approach - it s a little difficult to combine usage of custom formatter with another formatter like formatter : select in the example above . Nevertheless one can do it too : .. . .. . like the next demo http : www.ok-soft-gmbh.com jqGrid removeTextInColumn .htm . If you loads the data from the server then probably the best choice would be to modify the input data the input data for the column COL 2 inside of beforeProcessing callback . See the answer http : stackoverflow.com a 9855764 315935 or this one http : stackoverflow.com a 9722466 315935 for code examples . Comment : Great answer . Regarding Solution 1 I don t think is possible in Struts2-jQuery-Grid it does not have cellattr exposed since I m using checkbox formatter I will create a custom one with another formatter as in Solution 2b . Thanks a lot . Comment : It worked like a charm .

And the action where the CategoryList action is mapped is as follows . When a given edit link on the grid is clicked the load method is executed where a list of categories is loaded from the database . The list in the grid however displays nothing in edit mode when the edit link is clicked . I cannot find relative examples that may demonstrate this kind of thing . How to populate this drop down list especially how to give this drop down labels using the catName property and values using the catId of Long type property separately while category in the list has-many other attributes I don t find relevant examples to map a java.util.List E to sjg : grid . .. . .. . subCategory.category.catName is a nested property of Product entity . In this case even after populating the list it should also be noted that the display value of this column is catName category name of type String . The value of the selected item however to be set to an instance of Product should be catId category id of type Long which doesn t seem possible as the name of this column is subCategory.category.catName . Intuitively catId subCategory.category.catId would be mapped to catName subCategory.category.catName which would be wrong if I could envision correctly as-if the list were already populated .

This option is valid only for elements of type select - i.e . edittype : select and should be the URL to get the AJAX data for the select element . The data is obtained via an AJAX call and should be a valid HTML select element with the desired options One . You can use option group . your action has to return valid select element .

Reference : http : www.trirand.com jqgridwiki doku.php id wiki : common rules Comment : This can be done if there is s : select alone . Can we have s : select inside a grid column Comment : If I understand you correctly the select is rendered when there is no taglib declaration inside Product.jsp right I am sure that you have some taglib declaration in JSP where you have placed gridColumn element then it will work without additional declaration inside Product.jsp . Comment : Could you please demonstrate it in conjunction with an sjg : grid I cannot envision this thing .

Answer : One approach you could take is the Map-Reduce https : docs.mongodb.org manual core map-reduce way even though the JavaScript interpreter driven mapReduce http : docs.mongodb.org manual reference command mapReduce takes a bit longer than the aggregation-framework but will work since you will be using some very useful native JavaScript functions that are lacking in the aggregation-framework . For instance in the map-function you could use the trim https : developer.mozilla.org en docs Web JavaScript Reference Global Objects String trim function to remove any trailing spaces in your colourname fields so that you can emit the cleansed keys .

When I actually need : - .. . .. . Can anyone point me in the right direction Cheers Comment : What you are asking here is kind of possible but seriously speaking It s a bit nuts . How do we know who your writers are Please honestly think about this . If there is no writer3 for example in any of the data but somewhere you deem writer3 to exist then where do we get that from At any rate you are better off manipulating not there data in post processing rather than throwing this at the aggregation-framework . Just like with SQL queries . There are many things you can do but the real question is should I really be doing this . My answer is no you should not . Comment : it s not that the writer does not exist it is there but my aggregation does not return it as the writer does not have a review for the film specified in the match this results in the incorrect average score calculation . Comment : Please grasp the concept here . Adding data that does not exist should be done in post processing . Throwing in a list of possible writers creating zero score results on the server end will slow things down considerably . So even if there is a writers collection to source from and there are 10 writers and only 1 or 2 reviewed a film it is not efficient to throw all 10 at the server to produce results for . This should be simple to understand . Add them to your results with 0 scores when they are not part of the results returned . Much more efficient and sooo much simplier .

Answer : I would not do much aggregation on the main collection 3 billion records is quite a lot . One massive problem I can think with this is that any query will likely be huge returning a massive number of documents . Now it is true that you can mitigate most negative factors of querying this collection by using sharding to spread out the weight of the data itself however the sheer amount of data returned to the mongos will likely be slow and painful . There comes a time when no amount of index will save you because your collection is just too darn big . This would not matter if you was just displaying the collection MongoDB could do that easily it is aggregation that will not work well . I would do as you suggest : pre-aggregate into other collections based on data fragments and time buckets .", "Question : What is a preferred datastore for fast aggregating of data I have data that I pull from other systems regularly and the data store should support queries like : .. . .. . What is the number of transactions done by a user in a time range . What is the total sum of successful transactions done by a user in a time range . Queries should support sql constructs like group-by count sum etc over a large set of data . Right now I m using a custom data model in Redis and data is fetched in memory and then aggregates are run over it . The problem with this model is that this is closely tied to my pivots columns and any additional pivot if added will cause my data to explode leading to huge memory consumption on my redis boxes . I ve explored elasticsearch but elasticsearch queries with aggregations are taking longer than 200ms for the kind of data that I have . Are there any other alternatives I m also looking at Aerospike now . Can someone throw some light on how does aerospike aggregates work in this scenario .. . Answer : Aerospike supports aggregations on top of secondary index queries . Seems most of your queries are pivoted on user . You can build a secondary index on top of userid and query for all the data corresponding to a user . You can then slap the aggregation logic and filter the stuff based on desired time range . you need to do this because Aerospike does not yet support multiple where clause where you query for a user and a time range at same time . Your queries 1 2 can be done by writing an aggregation UDF based on a secondary index query on userid as above . I am not very clear about your 3 questions . Aerospike does not provide group-by sum count etc as native queries . But you can always write an aggregation UDF to achieve it . http : www.aerospike.com docs guide aggregation.html Comment : The aerospike.Query.apply http : www.aerospike.com apidocs python query.html aerospike.Query.apply method of the Aerospike Python client has an example of GROUP BY HAVING as a stream UDF .", "Question : I m trying to migrate our postgres database containing millions of clicks few years click history to more performing system . Our current analytic queries which are running on postgres are taking forever to complete and it degrades performance of the whole database . I ve been investigating possible solutions and I ve decided to closely investigate 2 options : .. . .. . HBase with Hadoop mapreduce .. . Cassandra with Spark .. . .. . I was working with NoSQL before however never used it for analytical purposes . At first I was a bit disapointed how little analytical query options those databases provide missing groupBy count .. . . After reading many articles and presentations I ve found out that I need to design my schema according how I intend to read my data and that storage layer is separated from query layer . Which adds more redundant data however in the world of NoSQL this is not an issue . Eventually I ve found one nice grails-plugin cassandra-orm https : grails.org plugin cassandra-orm which internally encapsulates orderBy feature in cassandra counters counters http : bflorian.github.io cassandra-orm guide 2 20Key 20Concepts.html 2.4 20Counters . However I m still worried about howto make this design extendable . What about the queries that will come in the future which I have no clue about today how can I design my schema prepared for that One option would be to use Spark but Spark doesn t provide data in real-time . Could you give me some insight or advice what are the best possible options for bigdata analysis . Should I use combination of real-time queries vs . pre-aggregated ones Thanks Comment : Hi Tomas can you add right tags to this question Hbase Spark are missing . nosql and nosql-aggregation may be duplicate . .. . Answer : If you want the ability to analyse data in near-real-time with complete flexibility in query structure I think your best bet would be to throw a scalable indexing engine such as Elasticsearch or Solr into your polyglot persistence mix . You could still use Cassanra as the primary data store and then index those fields you re interested in querying and or aggregating . Have a look at Datastax Enterprise http : docs.datastax.com en datastax-enterprise 4.0 datastax-enterprise srch srchIntro.html which bundles together Cassandra and Solr . Also have a look at Solr s Stats component https : cwiki.apache.org confluence display solr The+Stats+Component and its faceting https : cwiki.apache.org confluence display solr Faceting capabilities . These combined with the indexing engine s rich query language are handy for implementing many analytics use cases .

Answer : Let s say I gave you a list of person ids and I need to find out list of people and parks they visit . I would just join the tables and the result might look something like this where person id list is 1 2 3 4 5 . Now let s say there was a need to display the top 0-N parks that these people visit and then top N-2N parks and so on . A group-by query like this one would do the trick below N 2 . However this might become prohibitive if the dataset and person ids list gets large . Is there anything we can do to speed this up This question is NOT so much about optimizing the query or database server itself . Maybe we can introduce a caching Maybe not use a relational DB and use NOSQL Basically what are some good ways to optimize these aggregation type queries assuming we need to answer a wide variety of these often which includes sometimes grouping by other columns too . Comment : Be aware that not including park id in group-by will be problematic as well depending on DB used as will the LIMIT 2 component . I would simply do something like select p.name count as num visits from park p visits v where p.id v.park id group-by p.name and then do a ranking function ordered by num visits . You could record each visit by incrementing a value in the park table for each visit controlled by an after insert trigger on the visit table .

Answer : SQL-like aggregation functions are implemented in Aerospike using stream UDFs http : www.aerospike.com docs udf developing stream udfs.html which are written in Lua .

The stream UDF module let s assume it s contained in the file aggr funcs.lua would implement COUNT by returning 1 for each record it sees and reducing to an aggregated integer value .

You need to run a simple terms aggregation which in RAW json looks like : .. . .. . 2 . Your data field is stored as an nested document https : www.elastic.co guide en elasticsearch guide current nested-objects.html .. . .. . You have to add a nested subaggregation before doing terms aggregation . Both will output this : .. . .. . This unfortunately is just a raw query but I imagine that it can be translated into elastic.js https : github.com fullscale elastic.js quite easily . On top of that . If you re going to do aggregations don t forget to set your fields that you re doing aggregations on as not analyzed because it will start counting individual tokens as in documentation https : www.elastic.co guide en elasticsearch guide current aggregations-and-analysis.html aggregations-and-analysis .. . .. . I myself would store these documens as nested ones . Example : .. . .. . Mappings : .. . .. . Test data : .. . .. . Actual query : .. . .. . P.S . size : 0 means that I m letting Elasticsearch output all possible terms and not limiting its output as described in documentation https : www.elastic.co guide en elasticsearch reference current search-aggregations-bucket-terms-aggregation.html size . The size parameter can be set to define how many term buckets should be returned out of the overall terms list . By default the node coordinating the search process will request each shard to provide its own top size term buckets and once all shards respond it will reduce the results to the final list that will then be returned to the client . This means that if the number of unique terms is greater than size the returned list is slightly off and not accurate it could be that the term counts are slightly off and it could even be that a term that should have been in the top size buckets was not returned . If set to 0 the size will be set to Integer.MAX VALUE .

How can I transform the included Log4Net.config file using the same configuration transformation I realise that I could place another TransformXml into the AfterBuild target but is this the correct way of doing this transform or am I missing something Comment : I m having the same issue . Did you manage to solve it Comment : @MatiasCicero I ve solved it using an additional TransformXml in the AfterBuild target . I ve outlined it in the answer below . HTH . .. . Answer : I opted for the solution of using a base Log4Net.config file a Log4Net.XXX.config file for each build configuration and an additional TransformXml task in the AfterBuild target : .. . .. .

And an example Log4Net.Test.config looks like this I am using the transform to change connection strings and Log4Net s logging level : .. . .. . This transforms the Log4Net.config file in the output path successfully . It uses the same approach as transforming web.config files and so should be easily understandable by any other developer that picks up the project . Whilst this works and has been in production for a while now I m still looking for some confirmation that this is the correct way of doing transforms of included config files .", "Question : I am trying to have my TFS Build create the web.config-transform associated with the configuration I selected for my build . When I run the build I check the web.config file no transforms have been applied . When I a publish from VS2012 the transform works correctly . I have set up TFS 2012 Update 2 and have a separate server for builds . I don t have VS2012 installed on the build-server but I copied the C : Program Files x86 MSBuild Microsoft VisualStudio v11.0 Web and WebApplications folders and files from my dev machine to the build-server . I have created some configurations in my project and have added some tranforms to the associated web . configname .config . I have created a build and set the Items to Build - Configurations to Build to one of the configurations in my project .

Side question : Is that correct or should it show all the configurations I created So I run a build and check the output folder and the web.config has not applied the transforms . Is there anything else I need to do .. . Answer : Right click your solution file go to properties click configuration properties and click configuration Manager on the top . Make sure your configuration for different environment set properly . if it is not set properly set it properly and check in the code . Now go to your build template and check the configuration to build property in the process tab you must be able to see your different configurations . if the configuration is already set it properly you can also add the new configuration name by typing it in the build property . Note : you can also right-click your web.config-transform file and choose preview transform and make sure the transform config is working fine . you can also give the publish profile name if it is working properly int he msbuild arguments section", "Question : Currently I can easily setup Web.config transform based on build configuration e.g . use connectionString server . . for Debug and connectionString . SQLExpress . . for Release . But is it possible to do some Web.config transformation basing on web publish profile I.e . use connectionString server1 . . for profile Server1 and connectionString server2 . . for Server2 .. . Answer : I believe that the publishing profiles are independent of the build profiles which is a bit of a shame as you could easily accidentally deploy a debug configuration to your production servers . However if you re using MSDeploy there are ways to modify the web.config in there . See MSDeploy - Changing Connection string parameter after deploying the package http : blogs.msdn.com b webtopics archive 2010 05 13 msdeploy-changing-the-connectionstring-parameter-in-web-config-after-deploying-the-package.aspx for more details .", "Question : I am using Visual Studio 2010 .

Now when I build and publish my project I see an error message Comment : Are you setting the publish profile to Production during the publishing Comment : Maybe because the connectionStrings element does not exist in your base Web.config . You could try adding an empty node for it . Mine has a value I want for local debugging and I use replace transform instead of add . Comment : Yes . I double checked and the profile does use Production as build configuration . However I did notice an error in the output Web.Production.config 3 4 : Warning : No element in the source document matches configuration connectionStrings .. . Answer : Move connectionStrings to the main web.config . The only things that should appear in your production config are the transformations . Comment : The add is a transformation directive . Comment : My point is that there is no connectionString to transform so there s no need for it to be there . So either move it to web.config or remove it entirely . Comment : I m just assuming that he doesn t want the connectionString to be present during debugging since he s going through the trouble of adding it with a publish profile . Comment : I do need the the connection-string during development . that is why I in configuration manager I have a profile called Development . Comment : When I say debugging I m referring to you building locally and running the application from localhost which means you wouldn t be publishing .

For debugging I have the following configuration transform defined : .. . .. . web.Debug.config .. . .. . And I run the application in debug mode but my SMTP port is still taking the value from the web.config not web.Debug.config . Can anyone suggest what could be wrong in this configuration .. . Answer : Answering your question isn t simple because it poses a problem - if you want to transform Web.config with Web.debug.config - where transformation effect should be stored In Web.config itself This would overwrite transformation source file Probably that s why Visual Studio doesn t do transformations during builds . Previous Matt answer is valid but you might want to mix them to have generic solution that works when you actually change active solution configuration from debug to release etc . Here s a simple solution : .. . .. . 1 . Create your config transformations for configurations Debug Release etc .. . 2 . Rename Web.config file to Web.base.config - transformations should automaticly rename accordingly Web.base.Debug.config etc .. . 3 . Add following transformWebConfig.proj XML file to your project folder : .. . 3 . Navigate to your project properties choose Build Events and add following content to Post-build event command-line : .. . .. . Now when you build your solution a Web.config file will be created with valid transformations for active configuration .", "Question : For Visual Studio 2010 Web based application we have Config Transformation features by which we can maintain multiple configuration-files for different environments . But the same feature is not available for App.Config files for Windows Services WinForms or Console Application . There is a workaround available as suggested here : Applying XDT magic to App.Config http : vishaljoshi.blogspot.com 2010 05 applying-xdt-magic-to-appconfig.html . However it is not straightforward and requires a number of steps . Is there an easier way to achieve the same for app.config files .. . Answer : In my experience the things I need to make environment-specific are things like connection strings appsettings and often smpt settings . The config system allows to specify these things in separate files . So you can use this in your app.config web.config : .. . .. . What I typically do is to put these config-specific sections in separate files in a subfolder called ConfigFiles either in the solution root or at the project level depends . I define a file per configuration e.g . smtp.config.Debug and smtp.config.Release . Then you can define a pre-build event like so : .. . .. . In team development you can tweak this further by including the COMPUTERNAME and or USERNAME in the convention . Of course this implies that the target files x.config should NOT be put in source control since they are generated .

Answer : Visual Studio 2010 and 2015 does unfortunately not directly support it while you are debugging it is only intended for publishing - even with the extension SlowCheetah marked answer it does not work for me only for projects using app.config rather than web.config . Note that there is a workaround described at codeproject http : www.codeproject.com Articles 255781 Web-Config-Transformations-when-Debugging . It describes how to modify the .msproj file to overwrite the current web.config by the transformed version . I will first describe that workaround as Option 1 but I have recently found out another Option 2 which is easier to use so you may scroll down to option 2 directly if you like : .. . .. . .. . .. . Option 1 : I have added the instructions taken from the original codeproject article see the link above because the screen shots there are already gone and I don t want to lose the entire information : .. . .. . VS.Net doesn t do any transforming when you are developing and just debugging your local environment . But there are some steps you can do to make this happen if you want . First create the configurations you want in VS.Net assuming the default debug and release are not enough for what you are trying to accomplish . Right click on you web.config and select Add Config Transforms - this will create a dependant transformation config for each of your configurations defined . Now you can rename your web.config to web.base.config . Add a web.config to your project . It doesn t matter what is in it because it will get overwritten every time we do a build but we want it part of the project so VS.Net doesn t give us the Your Project isn t configured for Debugging pop-up . Edit your .csproj Project File and add the following TransformXml task to the AfterBuild target . Here you can see I will be transforming the web.base.config file using the web . configuration .config and it will save it as web.config . For details please check this https : msdn.microsoft.com en-us library ee942158.aspx Anchor 13 Microsoft Q A . .. . .. . Option 2 : .. . .. . Based on this http : stackoverflow.com a 21517589 1016343 answer I have developed a simple console app TransformConfig.exe in C 6.0 syntax : .. . .. . Ensure that you add the DLL C : Program Files x86 MSBuild Microsoft VisualStudio v14.0 Web Microsoft.Web.XmlTransform.dll as a reference this example applies to VS 2015 for older versions replace the v14.0 in the path by the appropriate version number e.g . v11.0 . Compile it and put the .exe file into a directory e.g . C : MyTools . Usage : You can use it in your post-build-event in project properties select Build Events then edit the Post-build event command-line . Commandline parameters are example : .. . .. . C : MyTools TransformConfig.Exe d : Web.config t : Web . ConfigurationName .config s : Web.Template.config b : ProjectDir .. . .. . i.e . first the name of the config file followed by the transform config file followed by an optional template config followed by the path to your project containing both files . I have added the optional template config parameter because otherwise your original complete config would be overwritten by the transform which can be avoided by providing a template . Create the template by simply copying the original Web.config and name it Web.Template.config . Note : .. . .. . You can also copy the TransformConfig.exe file to the Visual Studio patb C : Program Files x86 MSBuild Microsoft VisualStudio v14.0 Web where the transform .dll resides and refer to it in all your projects where you need to transform your configs . For those of you who are wondering why I added Environment.ExitCode x assignments : Simply returning an int from Main did not help in the build event . See details here . http : geekswithblogs.net dchestnutt archive 2006 05 30 80113.aspx .. . .. . If you re publishing your project and you re using a Web.Template.config ensure that you did a rebuild on your solution with the right configuration usually Release before you publish . The reason is that the Web.Config is overwritten during debugging and you might end up transforming the wrong file otherwise . Comment : Looks like the CodeProject post is pooched . He used screenshots for his code samples and now since his blog s down they re lost to history . Comment : Yes unfortunately the screenshots are gone . But at least the article text is still there describing the approach . I have added the text description to my answer to avoid losing it . Comment : Too bad you can t see the TransformXml task... .

To start with the transforms right-click your web.config file in the project explorer and choose Add Config Transforms . Assuming that you have ConfigA and ConfigB in your solution configuration there will be two new files added Web.ConfigA.config and Web.ConfigB.config . If you open these new files they ll be pretty empty except for a bunch of comments . They actually contain a connection-string example in them that you can use though - it looks like this : .. . .. . Uncomment this section and change the name property to the name of the connection-string in the base web.config file .

Answer : We keep all machine profile specific configuration in separate config files then use configSource to include them like so.. .

A sw architect on my team introduced slow cheetah in an overzealous way to our project and created debug stage and release transforms of all of our configs most of which needed no transformation .

To facilitate this I have built a structure like so : .. . .. . The web.base.config contains the untransformed base of the web.config data while the web . ENVIRONMENT .config contains the transform data based upon the current build configuration . The web.config contains the transform result that gets loaded at runtime . This works really well for us and has been very nice for staging changes . However there s a small issue that I ve thus far been working around manually : When I update my NuGet dependencies they apply their transforms to the web.config file which upon build then gets blown away with the transformations from my other configs . I have looked into a few different ways of fixing this and I haven t had any luck...Any ideas For the record this is how I achieved the above web.config schema in the project file : Comment : Can you add some specifics This should be a non-issue as far as I can tell . Comment : The issue is that the web.base.config is what should be updated by nuget rather than the web.config . But as far as I can tell there is no way to set that up on a project specific level as this is a team project with many engineers . Right now on build everything is fine - but on nuget update the web.config gets updated with the package changes and then blown away on the next build . I m currently gatekeeping all nuget changes and manually copying them on update to the web.base.config but we want to eliminate this step . Comment : Ahh. . I see now . I think you ve set it up backwards . By design web.config should contain all your base default debug values .

I don t think there is any setting that d let you say that use web.base.config instead of web.config . Your best bet is to follow the convention .

What statistical test can I use for 1 a single pair of species with trait A and trait B and 2 a group of species pairs consisting of species with trait A and trait B .. . .. . Also am I really dealing with pseudoreplicate data Any assistance is appreciated . Edit Data is pasted below . I am using the stand alone versions of Maxent and ENMTools so I do not have code . I have used R to try and analyze the data using t-tests and sign tests otherwise there is no code to add . Sample data : Comment : Need more code and datasets for this to be meaningful coding question . It s way too nebulous at the moment . Comment : Thanks . I pasted in some of my data but since the programs I used to generate the data are stand alone there is not any code to add . I am just seeking recommendations for data-analysis . Comment : The program I use to search for function that do new things is sos : : findFn . I get 128 hits in 24 packages for a search on maxent . There is also an R-SIG-epi mailing list . Comment : Maxent is a general term . I used Maxent species distribution modeling . Comment : A single vector for each species is offered but what connection to reality is presumed Are these measurements of some observable quantity at simultaneous sequential times with constant interval You are not doing a good job of explaining your domain in terms that a computer scientist might understand . Using sos : : findFn Maxent species distribution I still find a great many hits .", "Question : I recently downloaded MaxEnt Model v3.3.3e software from http : www.cs.princeton.edu schapire maxent website . I have troubleshot many issues and have success running the program with output files to view . However the output file does not provide me with a picture of the map . I do get the html document with all the statistics and plots and I also get a plots folder but I do not get a picture or map showing the niche model of my species . Would anyone know why this might be happening Would this have to do with what options I check before I run the program Any thoughts or suggestions would be most helpful . Thanks . Jacob .. . Answer : Have you ticked the option Make pictures of predictions in the main MaxEnt window In case you didn t realise MaxEnt will also create an .asc file by default which you can load into your GIS Software or R . This is probably the better way to go because you can then fully customise map colours and remove the black background", "Question : null .. . Answer : I m relatively new to MaxEnt and would like to explain my current understanding of the method below in the hope that someone can either 1 confirm whether my thinking is correct 2 incorrect or 3 somewhere in between . Regardless of the outcome I hope that others may be able to learn something from my ignorance based on any replies that appear below From my current understanding the raw output from MaxEnt is the ratio between the probability-density of covariates where the species is present i.e . f1 z and the probability-density of covariates at background locations i.e . f z . This only allows you to determine the relative suitability of one location over another . It cannot on its own predict probability of occurrence as there is no information on species prevalence . In order to circumvent this limitation and provide an occurrence probability MaxEnt has a Default Prevalence setting that transforms the raw output using the prevalence information you provide to calculate probability of occurrence logistic transformation . This is correct Assuming that you know a species prevalence with certainty very unlikely is MaxEnt s logistic output therefore an accurate probability map and not a relative one Does setting prevalence to 0 in the application s settings effectively create a logistic output that is the same as the raw output as there is no information on prevalence I wouldn t run a model with a logistic output and set prevalence to 0 but I am just trying to understand the model in greater detail . I hope this all makes sense Simon", "Question : null .. . Answer : I ve been reading this tutorial http : www.cs.berkeley.edu klein papers maxent-tutorial-slides.pdf on Maximum Entropy models and I fail to understand how to compute practically and also the difference between the predicted and empirical expectation which are obtained when when calculating the gradient of the log likelihood function pages 24-29 . The main thing I don t understand is how to get the predicted count empirical expectation from the posterior distribution I d be very grateful if someone could maybe point me to some literature where this is explained better . Thank you", "Question : Sorry if this question has come up before but I would like to ask if anyone knows what goes into each of the arguments in maxent from the dismo package I have searched the various R forum sites and the R help page itself but I couldn t understand how to put in my arguments . I have a sample of my data frame for the predictor variables here .. . .. . Each row is either a background or presence point . What I don t understand after that is what goes into the p and a arguments in the maxent formula . Does the p argument contain x and y coordinates and the 3rd column indicating 1 presence and 0 absence Or does column containing the 1s and 0s go into the a argument instead forest cover is a categorical variable . Please do tell me if I should be moving some of the stuff around and if they are in the right data frames . Thanks in advance Comment : Where does the maxent-function come from Did you read the help maxent . And in your last line you overwrite the function . Don t do that . Comment : Hi @Heroka thanks for your reply The maxent function comes from the dismo package and thanks for your tip on overwriting the function . I ve changed the code to not do that but it still doesn t work . Also included the error message too Comment : Did you load the dismo package first with library dismo Comment : @blindJesse yes I did .. . Answer : I don t know if this will help but my code looks like the following . You can set your arguments as below . If you open maxent.jar and click the help button in the MaxEnt GUI you will get a list of arguments . Simply type in the name of the argument and set its value and it should then work . EDIT : I should add that x is my raster stack of covariates in this case BioClim layers and p is simply a list containing xy coordinates in that order for my species .", "Question : I am trying to fit some species distribution models using the biomod2 package in R . .. . .. . I have compiled all of the required data such that biomod2 successfully fits models using all techniques except MaxEnt which throws an error : .. . .. . I thought this might be because biomod2 wasn t managing to find MaxEnt or Java but I have the rJava package loaded and have tried running MaxEnt in the dismo package in the same R session and it runs fine . Does anyone have any idea what might be going on Thanks Andrew .. . Answer : Just to let any users who are interested know I finally solved this . It seems that MaxEnt in biomod2 will not accept spaces in the file path to the maxent.jar file at least some of the time . I moved my files to a different directory without a space and it now runs .", "Question : null .. . Answer : Recently I have been familiarising myself with the MaxEnt GUI v3.3.3k and have been successful in producing a range of models for species of interest to me . For increased reproducibility I have decided to use the Dismo package and run MaxEnt through R . .. . .. . I have noticed something very strange when comparing the outputs of the two methods however . Using exactly the same environmental layers and occurrence records I end up with two wildly different predicted distributions when using anything but the default values . For my first test I opened the MaxEnt GUI and leaving all settings at default ran the model for my species . I then ran the exact same model using the following code within R and when plotted I got identical distributions as expected . However if I change the beta regularization multiplier to anything except default the maps look totally different . For example if I set regularization 0.5 and prevalence 0.80 in the GUI and run the model keeping all other settings exactly as default but do the same in R with the following code then it all goes wonky . Interestingly the AUCs and variable contributions all look nearly identical for the two models . I would have assumed therefore that the maps wouldn t look so wildly different . I have uploaded the maps to the following location so you can see for yourself the discrepancy . Maps discrepancy http : i.stack.imgur.com zrSqJ.png .. . .. . When analysing the two HTML outputs from running the models default and non-default I have only noticed the one difference . When using the GUI with 81 presence records and 10 000 background points I am told that 10020 points used to determine the Maxent distribution background points and presence points . However when using R I am told 10081 points used to determine the Maxent distribution background points and presence points . As I mentioned previously all other settings were kept the same so points haven t been used in cross-validating for example . I was wondering if anyone else had come across this issue before . Am I doing something fundamentally wrong within R for the two distributions to be so different I was under the impression that within R all other settings would remain as default in the GUI unless you specified certain arguments as in the second code example above .", "Question : null .. . Answer : i am trying Maximum Entropy in weka for text classification . I am using Logistic Regression in Weka which is equivalent to Max Entropy . I read that its is computantially expensive .

Answer : I am trying to run an ensemble species distribution however the the results I am getting for MAXENT.Phillips model are not reasonable projections compared to the Random Forest and Boosted Regression models that I am using .

I feel like that is very different in a way from this set of probabilities : .. . .. . Is there a way to score the difference between these two .. . Answer : The problem you are facing is often called the consensus among classifiers . As multilabel MaxEnt can be seen as N independent classifiers you can think about it as a group of models voting for different classes . Now there are many measures of calculating such consensus including : .. . .. . naive calculation of the margin - difference between the winning class probability and the second one - bigger the margin - more confident the classification .. . entropy - smaller the entropy of the resulting probability distribution the more confident the decision .. . some further methods involving KL divergence etc . In general you should think about methods od detecting uniformity of the resulting distribution impling less confident decison or spikeness indicating more confident classification . Comment : +1 for entropy . Fun fact : The reason why Max Ent classifiers are called that way is that they try to maximise the entropy of P output input while respecting the training-data . In a way the classifier tries to find the most unbiased probability distribution that is in line with the training-data . Comment : Uniformity is the wrong thing to go for---poor probability models can often provide very spiky posteriors which are entirely incorrect . You need to reference the correct posterior through cross-entropy KL Divergence as you suggest to ensure that your distribution is correct . After all uniform posteriors might actually be accurate.. .", "Question : I hope I have come to the right forum . I m an ecologist making species distribution models using the maxent version 3.3.3 http : www.cs.princeton.edu schapire maxent function in R through the dismo package . I have used the argument replicates 5 which tells maxent to do a 5-fold cross-validation . When running maxent from the maxent.jar file directly the maxent software an html file with statistics will be made including the prediction maps . In R an html file is also made but the prediction maps have to be extracted afterwards using the function predict in the dismo package in r . When I do this I get 5 maps due to the 5-fold cross-validation setting . However and this is the problem I want only one output map one summary prediction map . I assume this is possible although I don t know how maxent computes it . The maxent tutorial see link above says that : .. . .. . ...you may want to avoid eating up disk space by turning off the write output grids option which will suppress writing of output grids for the replicate runs so that you only get the summary statistics grids avg stderr etc . . A list of arguments that can be put into R is found in this forum https : groups.google.com forum topic maxent yRBlvZ1 9rQ . I have tried to use the argument outputgrids FALSE both in the maxent function itself and in the predict function but it doesn t work . I still get 5 maps even though I don t get any errors in R . .. . .. . So my question is : How do I get one summary prediction map instead of the five prediction maps that results from the cross-validation I hope someone can help me with this I am really stuck and haven t found any answers anywhere on the internet . Not even a discussion about this . Hope my question is clear . This is the R-script that I use : .. . .. . model1 -maxent x predvars p presence points a target group absence path home .. . model1 args c replicates 5 outputgrids FALSE .. . .. . model1map -predict model1 predvars filename home .. . model1map.tif outputgrids FALSE .. . .. . Best regards Kristin Comment : For those who want evaluation statistics on Maxent models with multiple types of cross-validation including those that use spatial partitioning of test data check out the ENMeval package in R . The output is a table of stats that you can use to choose an optimal model and averages of AUC and omission rate are calculated automatically over your k folds . It also outputs AIC . .. . Answer : Sorry to be the bearer of bad news but based on the source code https : github.com cran dismo blob master R maxent.predict.R it looks like Dismo s predict function does not have the ability to generate a summary map . Nitty-gritty details for those who care : When you call maxent with replicates set to something greater than 1 the maxent function returns a MaxEntReplicates object rather than a normal MaxEnt object . When predict receives a MaxEntReplicates object it just iterates through all of the models that it contains and calls predict on them individually . So what next Fortunately all is not lost The reason that Dismo doesn t have this functionality is that for most kinds of model-building there isn t actually a valid way to average parameters across your cross-validation models . I don t want to go so far as to say that that s definitely the case for MaxEnt specifically but I suspect it is . As such cross-validation is usually used more as a way of checking that your model building methodology works for your data than as a way of building your model directly see this question http : stats.stackexchange.com questions 11602 training-with-the-full-dataset-after-cross-validation for further discussion of that point . After verifying via cross-validation that models built using a given procedure seem to be accurate for the phenomenon you re modelling it s customary to build a final model using all of your data . In theory this new model should only be better than models trained on a subset of your data . So basically assuming your cross-validated models look reasonable you can run MaxEnt again with only one replicate . Your final result will be a model accuracy estimate based on the cross-validation and a map based on the second run with all of your data lumped together . Depending on what exactly your question is there might be other useful summary statistics from the cross-validation that you want to use but those are all things you ve already seen in the html output .

Comment : Are you interested in using the pure Maxent classifier from OpenNLP or the higher level API that used maxent .. . Answer : The following code might help although it does not use the ContextGenerator explicitly . Actually the BasicContextGenerator is used within the BasicEventStream and it just splits each input string into a list of features . e.g . the String a 1 b 2 c 1 is split into 3 features : a 1 b 2 and c 1 .

Answer : I won t attempt to answer completely your broader question about the best practices of adding scripting . It seems to me that choosing between hook-based solution in which you define hook implementations by name convention and they are automatically recognized and explicit api solution in which you use functions predefinied in the scripting enviroment to register your hooks or otherwise call configuration functions is largely a matter of taste . Explicit calls like set-connection-timeout-handler .. . may be more readable easier to debug no misspelling problems no surprises on api changes easier to document and a bit more flexible but more well explicit . Building from your simple variable definition example here are a few ways you could get started going further the interpreted path : Comment : +1 This answers my question and puts me in the right path . Before getting this reply I was reasoning about the two scripting patterns you quoted ending that probably the best solution could be return a data structure from LFE like a tuple . You explain this and a lot more.. . The reply really helped me . It would be great to have this explained in LFE docs or also in a blog post .

Ideally I d be able to do something like .. . .. . But there doesn t seem to be lfe support in erlc . The best solution I can think of off the top of my head is .. . .. . but that seems inelegant .

I copied the lfe shell script as a batch-file replacing @ with 1 2 3 4 and it gives me this : .. . Answer : The problem here is that Erlang can t find the LFE ebin directory . Two ways to solve this problem are : .. . .. . Use an explicit -pa lfe ebin dir argument when starting LFE either in the lfe.bat script or when you call it . Simple but hard wired . Use the ERL LIBS environment variable . This is described in the code module documentation http : erlang.org doc man code.html . If you create an extra Erlang library directory say c : projects erlang drop Erlang apps which follow the Erlang application directory structure as LFE does and point ERL LIBS at it then the code server will automatically add ebin directories it finds there to its code path . This is also described in How do I install LFE on Ubuntu Karmic http : stackoverflow.com questions 2835942 how-do-i-install-lfe-on-ubuntu-karmic but in a UNIX context . The ERL LIBS feature should definitely be better advertised . EDIT : Replying to @Shantanu Kumar s comment . I don t have access to a Windows machine so I can t test it properly . The problem seems to be that using lfe boot tries to start the port program ttysl which doesn t seem to work on Windows at least not when running erl.exe . Some solutions to try : .. . .. . Use werl.exe instead . This may work but I would do it anyway . Try starting Erlang in the normal way with werl.exe -pa ebin to get the right load path and manually starting the LFE shell with lfe shell : server . .. . .. . Try starting Erlang with werl.exe -pa ebin -noshell -s lfe shell start . This will run lfe shell as the shell but the G won t be available . Also while it is nice to use it you don t need to use the LFE shell to run LFE you can use the normal Erlang shell and just call the LFE functions in the normal way . You might become a little schizophrenic with two io formats but there are no problems . : - .. . .. . Hope this helps . Comment : I did as suggested and got this : C : temp lfe erl -pa ebin -noshell -noinput -s lfe boot start ERROR REPORT 18-Jan-2011 : : 00 : 22 : 52 Error in process 0.28.0 with exit value : badarg erlang register user 0.29.0 user start port 1 Comment : The second option werl.exe -pa bin followed by lfe shell : server . works . It also works with plain erl.exe however when I specify -noinput or -noshell or -s lfe shell start with werl.exe or erl.exe it starts causing error .", "Question : I ve read through all the documentation and most of the source of LFE .

And then you know it mumbles something about having added up some numbers and the answer being 7 . .. . Answer : There is a serious lack of examples in the LFE release all contributions are welcome . Christian s suggestion is correct . My only comment is that there is no need to have capitalized variable names it is not wrong but not necessary . The LFE let is a real let in which the variable bindings are visible first in the body . You can use patterns in let . There is also a let form macro actually which binds sequentially . No I have so far kept all the Erlang core function names just as they are in vanilla erlang . It is definitely more lispy to use - instead of in names but what do you do with all the other function names and atoms in OTP One suggestion is to automatically map - in LFE symbols to in the resultant atoms and back again going the other way of course . This would probably work but would it lead to confusion I could then have a behaviour module looking like : .. . .. . But I am very ambivalent about it . Comment : It would probably lead to confusion . Imagine all the time that has been spent informing users of Common Lisp that atom names are not case insensitive but that the reader is just uppercasing atoms before interning them . Comment : My small experience is that the syntactic mapping between lisp and erlang disappears very quickly from view which means that a coder will read erlang source and mentally translate it by substituting parentheses for commas etc . I think another step of rewriting identifiers would trip me up almost every time as I would only be looking to rewrite syntax . I vote against the substitution .", "Question : I ve read through all the documentation and most of the source of LFE .

Is there an example how I would create a hello world source file and compile and run it .. . Answer : No there is nothing you missed . The Makefile in LFE is less than perfect and should be ignored it will be improved upon in the next release . To compensate all the needed files have already compiled and the .beam files are in the ebin directory . As it is not part of OTP I don t think it should ever install there . The easiest way to handle this to create a private erlang library directory and point the environment variable ERL LIBS to it . Then just drop the whole LFE directory there . When erlang starts the code server will automatically add the lfe ebin directories into the path and the .beam files there will automagically be found and loaded . This will work with any package that contains an ebin directory . This also works on Windows . So : .. . .. . 1 . Make an libs directory say erlang lib .. . 2 . Set the environment variable ERL LIBS export ERL LIBS erlang lib .. . 3 . Put the whole LFE directory there .. . .. .

I know about the pseries object from the plm package which can handle panel regression with lags . Is there a similar solution in the lfe package for panel objects so that I can take advantage of the speediness that lfe provides .. . Answer : There is no direct way to do lags in felm as of now but it is possible to do it as follows : .. . .. . The reason the lag does not work straight away with felm is that it will use the default lag function not the pseries lag . When specifying it as above the pseries lag is used . Another way to make it work is : .. . .. . I.e . include an explicit as.data.frame this will convert Em to a data.frame with appropriate attributes . This will incur a copy of the entire dataset but is no different from what plm does behind the scene . Comment : The next release of lfe in a month or so will support this directly with pseries provided plm is loaded . It turned out to be a very simple fix . At a single point when I create the model frame I have replaced an as.formula with an as.Formula . The class of wage is then preserved and the right lag will be used . Comment : The current version of lfe 2.3 handles this i.e . felm emp output+capital + lag wage 1 firm data Em will use the pseries lag .", "Question : I am using the lfe package in R to do some regression with lots of fixed effects so direct lm is out of the question and since the fixed effects are not individual-level so is plm . I get the output with no problems but now I d like to use it in a LaTeX table . However none of the packages I tried like xtable apsrtable the latex command in Hmisc and so on have methods for objects of class felm . So my question is what do I do Is there a way to access the lm.method and twist it so it can read felm objects Is there a way to coerce felm objects into lm form Any ideas .. . Answer : As the author of the lfe-package I can shed some light on this . It is true that the felm-object mimics the lm-object but with some differences . It does not contain a copy of the data-matrix . The lfe-package is intended for very large datasets in the gigabyte-class . Thus some effort has been made to conserve memory . Another difference is that the felm-object does not contain information about the rank of the system in the same manner as lm nor the qr-decomposition used by lm . felm does not use a qr-decomposition and the rank can be a somewhat complicated matter . The upshot of this is that some standard methods will work on felm-objects whereas others will not . An early version of lfe actually had lm as an inherited class for felm but since this creates the impression that it actually is an lm-object I removed it .", "Question : null .. .

Answer : This might not be the answer that you are looking for but it seems that the author did not add any functionality to the lfe package in order to make predictions on external data by using the fitted felm model . The primary focus seems to be on the analysis of the group fixed effects . However it s interesting to note that in the documentation of the package the following is mentioned : .. . .. . The object has some resemblance to an lm object and some postprocessing methods designed for lm may happen to work . It may however be necessary to coerce the object to succeed with this . Hence it might be possible to coerce the felm object to an lm object in order to obtain some additional lm functionality if all the required info is present in the object to perform the necessary computations . The lfe package is intended to be run on very large datasets and effort was made to conserve memory : As a direct result-of this the felm object does not use contain a qr decomposition as opposed to the lm object . Unfortunately the lm predict procedure relies on this information in order to compute the predictions . Hence coercing the felm object and executing the predict method will fail : .. . .. . If you really must use this package to perform the predictions then you could maybe write your own simplified version of this functionality by using the information that you have available in the felm object . For example the OLS regression co fficients are available via model2 coefficients . Comment : Helpful comments .

This is the usual first guess when looking for differences in supposedly similar standard errors see e.g . Different Robust Standard Errors of Logit Regression in Stata and R http : stackoverflow.com questions 27367974 .

It also appears that summary est returns the output that would be expected by a user of lm . This does not actually do what you asked .

Answer : If I understand correctly you re able to do the user logout at the 5 minute mark I presume via the timer event handler but if the print dialog was open then the printout can still end up happening . The question is what s really the important thing here closing the dialog or preventing the subsequent printout Also are you logging out the user but keeping the program going or is the program quitting If the app is supposed to shut down then your code can call the Application object s Shutdown method which will close any modal dialogs as part of the shutdown process . If the app is supposed to keep running without a current user then I would think the White library is your best bet . It s unclear why you ve moved away from this . With or without closing the print dialog however the printing code should check to see if the user is still logged in before it actually prints something .

Answer : You could try using a http cache but I don t think it would work as the Safari View Controller is working as a separate process probably the same as Safari so that s why it e.g . circumvents ATS . The only way I can think of this working is to somehow force the user s Safari to load it openURL : or adding to Reading List maybe This doesn t sound like a viable solution . You can always experiment with custom presentation of the view controller attach it the view-hierarchy trigger appearance events but set its frame to CGRectMake 0 0 1 1 or attach it somewhere off-screen then wait a while and represent it with a correct frame .

So I assume that it may work for SFSafariViewController . Comment : I will send you same after some time . I busy with some urgent task . .. . Answer : Sadly this behaviour is not supported with the current implementation of SFSafariViewController . I would encourage filing a radar with Apple to add support for this behaviour but like others have suggested your best bet is to use WKWebView and start loading before its added to the hierarchy . I came across a lovely radar from Twitter https : openradar.appspot.com 21349835 that actually mentions exactly what you re asking for . I think you might find the following requests useful : .. . .. . High Priority : - Ability to warm the SFSafariViewController before actually presenting it with a URL URL request HTML data or file on disk - Currently are investing heavily into warming the shared URL cache for high priority Tweets so that if the user hits that Tweet we will open UIWebView sadly not WKWebView with that pre-cached web page . If we could just warm an SFSafariViewController with the desired link this would eliminate an enormous amount of effort on our end . You can see in their implementation they simply cache responses using UIWebView since WKWebView seems to obfuscate the caching semantics a bit . The only risk is that UIWebView is a likely candidate for deprecation as you see in their docs https : developer.apple.com library ios documentation UIKit Reference UIWebView Class In apps that run in iOS 8 and later use the WKWebView class instead of using UIWebView . So unfortunately it seems that their are many hoops you need to jump through to get this all going so your best bet for now is to just pester Apple and dupe Twitters radar . Comment : I seriously doubt Apple would ever support this . Twitter has no way of knowing whether or not a user will actually want to tap a high priority tweet so they re just wasting everybody s battery and data .", "Question : Is it possible to load content to SFSafariViewController like it was in UIWebView with loadHTMLString : method I tried to find anything about it but it seems that SFSafariViewController can show only Internet data is it true .. .

Is this possible I tried this with no luck : .. . .. . Is it required that the Safari view be full screen .. . Answer : Using JAL s answer as a base I was able to implement this myself in an app that had existing structure with tabs already . I wanted tab 3 to go into a Safari controller within the tab after a button was pressed on the existing view and not pop the Safari controller into its own window like it does using Apple s default code . The key was to swap in a SFSafariViewController into the existing UITabBarController s array of view controllers . I saved the existing original view controller on tab 3 index 2 to come back to it when the Done button was pressed on the Safari controller . Here s what I did to go into the Safari controller from with my tab when a button was pressed : .. . .. . Then I could swap back to the original view on that tab like this when the Done button was pressed on the Safari controller using this delegate call : .. . .. . When I swapped controllers in an out of the tabBarController view controller array I lost my tab icon and tab name so I had to set those . Here is how I fixed that issue and kept my theming when the tab icon was touched : .. . .. . I must admit that I am not sure that Apple intended that the SFSafariViewController be used in this way within a tab based on what the normal behavior of calling SFSafariViewController currently does . Just be aware that future iOS updates may change this behavior and always test your code when new iOS versions go into Beta .", "Question : null .. . Answer : In a traditional UIWebview we can easily inject javascript into the web page loaded within the web view . Is there a way to do this in SFSafariViewController SFSafariViewController works great for my needs because it can access cookies and I need this to allow an already authenticated user to access a web site . But my native iOS app has to be able to fill in form fields within the loaded web page . The native app will be responsible for launching the device camera and scanning a barcode then injecting the barcode text back into specific field on the web page . I can easily do this if I can just inject javascript into the Safari View . Any thoughts Is this something that is restricted I cannot find any info on this . thanks Comment : You could research using a custom NSURLProtocol . This can be used to intercept and handle all traffic that goes to from a normal UIWebView but I don t know if this will allow you to see and handle the traffic from a SFSafariViewController or if that traffic happens outside of the sandbox of the app . But it s worth looking into . If I had to guess though I would assume it won t work because this would basically allow someone to get private data from a user s web browser cookies and stored passwords without the user knowing .

Comment : You can try something like : self.navigationItem.rightBarButtonItem nil Comment : @CraigOtis : Doesn t appear to work as the Done link is still rendering . I d prefer to remove the entire nav bar . However I wonder if in the context of SFSafariViewController navbar refers to the bottom navigation menu . Comment : It shouldn t - the bottom menu is the toolbar I think a better approach might be to switch to UIWebView if you re needing a fullscreen solution . .. . Answer : Put this code in viewDidAppear : .. . .. . To hide the status bar set View controller-based status bar appearance to YES in your info.plist file and insert this in your view controller . Warning : I will suggest you against using SFSafariViewController for full screen view because reloading is not possible since reload button is in UINavigationBar . In case request fails it will render the application useless . Rather go for full screen WKWebView with custom toolbar instead . Update : To avoid hiding the reload button just add a view imageView over the done button in your SFSafariViewController and render button invisible or at least untappable . The problem with this approach is only that overlay stays on screen but if you can find a nice image for it you will be fine . Comment : Ic so the suggestion is to move the svc object up 64 pixels thereby hiding the navbar . It works . The only issue left is the prefersStatusBarHidden override doesn t seem to be working as the status bar is still rendering . Comment : I updated the answer .

When I start my Web App with an empty Cache Cookies the App is unable to load throwing me a lot of errors similar to these : WebApp errors http : i.stack.imgur.com 37iwY.png .. . .. . The reason for these errors is the fact that the GET-requests for the resources are answered with code 401 which is a text html . This means that my WebApp is not authorized to fetch the .css and similar resources from the icCube-server . Logging into my icCube interface solves the errors as that authorizes my browser session to get data from my icCube server . Is there any workaround for this problem As far as I know the resource URIs are generated from the ic3root and ic3rootLocal passed to the ic3Start-function on the html-page which means that I can not just pack all the .css-files into my apache folder and link them . Is it possible to authorize my WebApp to get these resources based on the same authorization process used to get my report selection proxy configuration .. . Answer : It looks like because Apache does not secure the icCube URLs with its Basic Auth . configuration and let non-authenticated requests reaching the icCube server . Note 1 : You can access public HTML resources i.e . with no authentication required . For that you can use the icCube.xml property see doc . in the file . Note 2 : You can deploy the icCube Web Reporting application with you Web App HTML files in Apache and configure the Web Reporting for accessing icCube server elsewhere worth a different question . Comment : With Note 1 do you mean rewriting the ic3bootstrap.js to fetch all scripts etc . from the public directory instead of the default Also can I find documentation on your Note 2 anywhere Sounds like a reasonable solution too . Comment : Conceptually Note 1 would be very much similar to Note 2 . Note 2 your Web App will contain the icCube Web Reporting application as well . On top of my head you would need to change the location of the icCube GVI servlet to access the report definition and the OLAP engine for the MDX requests . Worth a different question .

The Application page is hosted on a server different to the IcCube-server . The server is currently a local Apache server xampp using Basic Auth to authenticate users before they can access my htdocs . I would like my Apache to do the authentication while icCube s internal authorization manages report access with only a single login being required . My application is based on the live demo for web reporting http : demo3.iccube.com icCube doc tutorial ic3report-tutorial.html provided by IcCube therefore it s using explicit JavaScript authentication it s getting the demo user data through ic3.getDemoDataSourceSettings . After trying to work through the IcCube documentation http : www.iccube.com support documentation reporting doc ic3WebAppIntegration.php on the matter I am just as confused as before . The related page on Apache configuration lists possible configurations for Apache icCube but I don t understand which I should use advantages disadvantages and if all of them even work with our server setup . 1 .

Comment : Not sure to understand why you would need an explicit login . Apache Basic Auth . is performed meaning the GVI requests sent by your Javascript files will be authenticated on the server-side meaning the list of reports returned depends on the authenticated user .

But I haven t an idea about the process of adding plugin in icCube . Any help or suggestion please thank you .. . Answer : Accessing SQL server tables is performed through a JDBC driver www http : www.iccube.com support documentation user guide schemas cubes ds database.php . So create a new SQL data source and select the SQL Server driver . Then enter amongst other the address of the SQL server and leave blank the port-number default : 1433 .

There are only 2 schemas that load on startup . Normally one loads in 1 minute and the other in 14 minutes . But now they both will not finish even after several hours . Last info in the log is LOAD SCHEMA PHASE I full-load started .. . .. . The machine is not busy on disk and no CPU . The Postgresql server it loads from is not running any query for the icCube server . In the builder I can open a schema but if I want to browse a simple dimension it freezes . I solved it by disabling load on startup and deployed loaded the schema from the builder . We use 64 bits Java 1.8.0 77 . Is this a known problem Other things I can check Thanks Comment : are you running out-of-memory check iccube logs for this you ll see a lot of Full GC Comment : No we are not running out-of-memory we were before but I stopped many loads . The Java settings are with 2GB max heap . According to icCube the schema s are using around 140MB and 100MB .

I have ghost installed and also have a proxy the host is host http : XXXXXXXX and port 7676 . But I get an empty html string . I also tried with ghost.set proxy type https host host port port but it fails html string remains empty . When home with no proxy and thus without the line ghost.set proxy type http host host port port it works . I am udner a Win 64 Bits OS with the proxy already settled in Advanced Settings . Would you have any idea of what I am missing .. . Answer : Most HTTP libraries use the proxy you specify in the corresponding environment variable so running .. . .. . should help on unixoid systems at least . When you use something like wget to access the URL through a proxy and still get an empty reply make sure your proxy is configured correctly you re using the right credentials and your remote-server is not behaving strangely with things that are behind a proxy which I wouldn t assume with google . EDIT : just realized : You re only setting a HTTPS proxy some elements on the page you re requesting might be fetched via HTTP not S and without a proxy for that this might fail . Comment : But export is not a Python command I am on Windows and already configure the proxy in advanced settings but seems like Qt is not detecting it automatically . Comment : That s why I recommended checking the proxy functionality with something simpler than ghost.py . Windows always lacks the most basic tools that everyone else s OSes come with so most probably something based on urllib2 in python would be a good test .

The proxy works with urllib2 with proxy support urllib2.ProxyHandler proxies opener urllib2.build opener proxy support urllib2.install opener opener . But that s not the point . I am talking aobut ghost.py under - I should have mentionned it - a WinOS .

In this case it looks like the client is pyscripter and the server is a subprocess running your app and it sounds like the subprocess crashed so hard that it did not gracefully close the connection or send back a meaningful traceback . So either there is a bug in pyscripter or a bug in your code . My advice is to run your app without the IDE and see if you can reproduce the issue and get a meaningful traceback . Comment : I ve tried running from the command-line but unfortunately it crashes without leaving a traceback . In fact it crashes most of the time in the IDE without a traceback but every now any then I get what was posted . Comment : @user1379351 Unfortunately that sounds like a hard crash i.e . some C extension or even python itself segfaulted . If you re up to the task you can attempt to debug the issue with Visual Studio or WinDbg but if you re not familiar with C or assembly it s going to be tough ." ] }

So at least -lmingw32 is in other position in libraries to be linked and also -Dmain SDL main was missing . The library SDL2main is a static library so it needs mingw32 to be prior to it when linking . From SDL FAQ for windows https : wiki.libsdl.org FAQWindows .. . .. . You should be using main instead of WinMain even though you are creating a Windows application because SDL provides a version of WinMain which performs some SDL initialization before calling your main code . If for some reason you need to use WinMain take a look at the SDL source code in src main win32 SDL main.c to see what kind of initialization you need to do in your WinMain function so that SDL works properly . If there is something like sdl2-config available in case of any library I would at least check what it outputs . Comment : If that was the case then there would have been undefined-reference to SDL main but it isn t . Comment : @keltar my guess is that -mwindows translates main to be WinMain and then WinMain in SDL2main library is discarded as duplicate and won t be referenced and thus SDL main won t be referenced . Comment : No libmingw32.a references WinMain and cannot find one . ld linker is sensitive to libraries order especially when libraries are static . Your order is correct so it linked order in question isn t .

I have one project for each platform now I want to abstract the SDL stuff to a common project that each platform project will reference with each project supplying the appropriate SDL libs for the platform through the linker . Is there a project type in VS that actually allows me to do this I was hoping the shared items project would do the trick but I doubt thats the one . There does appear to be some form of shared library for iOS and Android but it doesn t look like that extends to Linux and Win32 . Thanks Comment : Visual C++ and cross-platform doesn t go well together . .. . Answer : To make a successful cross-platform application with SDL2 you should in first place use a compiler that s available on both platform . Because you will need to compile a binary for each platform . SDL2 seems to support IOS and Android out of the box but I don t know how deployment is done for the mobile OS . You can still use Visual Studio with CMake or a Makefile and use another compiler instead of Visual C++ to support a cross-platform build like g++ mingw32 on windows or Clang . Comment : VS has an ARM compiler now for iOS and Android dev and for Linux it creates a connection to a Linux dev machine where I believe it calls the gcc compiler and sends it the source files .

Comment : Thank you for the comment I considered this but since everything works with CMake I m not sure that the libraries are incompatible . It is probably possible that CMake does something weird like duplicate the libraries to create a new file structure but if that s the case surely I can do it with Make too I ll double check to see if there are new library versions .

I m looking forward to picking up both SDL2 as well as SFML2 libraries for game dev . and other stuff . Now I know for a fact that both SDL2 and SFML2 are capable of creating OpenGL enabled contexts through which OpenGL graphics programming may be done . But online I ve read discussions wherein people said something to the effect of SDL 1.2 is software accelerated SDL2 and SFML2 are hardware accelerated by default . I know that software rendering is graphics using CPU alone . While Hardware rendering uses graphics cards pipeline . So my question is with regards to these game libraries : .. . .. . Part 1 : when someone says one is software hardware acc.by default what does he mean Is it that my guess if say SFML2 is hardware acc . by default even basic 2d graphics are done by it using hardware rendering as the backend pipeline to do it even if I didn t explicitly do any hardware-rendering programming in the code Part 2 : And if that is true is there any option within these libraries to set that to software acceleration rendering Part 3 : Which of these 2 libraries SDL2 vs SFML2 has better overall performance speed Thanks in advance for any answer and apologies if you found the question dumb . .. . Answer : Cannot say anything about SFML but almost sure things are very close but for SDL it is as you say . In SDL1 2d drawing implemented as blitting directly on display surface and then sending this surface to display - so mostly software although minor hw acceleration is still possible . SDL2 have SDL Renderer and textures which are GPU-side images or render targets and any basic drawing that uses renderer may be accelerated by one or another backend . Which backend will be chosen depends on system your program runs and user settings - e.g . it would default to opengl for linux d3d for windows but still can use opengl opengles for android ios etc. . .. . .. . You can use software renderer either by explicitly calling SDL CreateSoftwareRenderer https : wiki.libsdl.org SDL CreateSoftwareRenderer or hint https : wiki.libsdl.org SDL SetHint SDL to use software https : wiki.libsdl.org SDL HINT RENDER DRIVER driver or even override it by setting SDL RENDER DRIVER environment variable . If you intend to use opengl for 3d graphics - then you just ignore all that and create window with opengl context as usual and never use SDL Renderer . Comment : By the hint and SDL RENDER DRIVER parts did you mean simply using the software rendering substitutes meant for software rendering OpenGL D3D calls on that system eg . Mesa driver for OpenGL Swiftshader for D3D Comment : Sorry I cannot understand your comment . Basically it requests SDL to use different implementation for all rendering functions e.g .

Answer : To be able to use SDL2 on Xcode you must set two things which are required for SDL in general : .. . .. . where to find header-files so that Clang can compile with -Iheader path .. . where to find the .dylib to link it to the project since with brew you don t have a real .framework .. . .. .

Answer : The example code is simply demonstrating the most portable way to render to the screen . Your app doesn t necessarily control whether the OS uses double or triple buffering so you can t rely on a single render being consistently presented to the user . Also there are potential situations where the default framebuffer contents can be lost altered . In other words you should be rendering every frame .

I see that there s just one docker run .. . command . Would really appreciate if I could get to know what the aforementioned command does that results into 4 containers 1 master 1 slave 1 zk 1 marathon running on my laptop . .. . Answer : containersol minimesos runs the Java code that is the core of minimesos . It only runs until it executes the command from the CLI . When you do minimesos up the command name and the minimesosFile will be passed to this container . The container in turn will execute the Java code that will create the other containers that form the Mesos cluster specified in the minimesosFile . That should answer 3 also . Take a look at MesosCluster class thats the root of where the magic happens . I don t know the answer to 2 will get back to you when I find out . Comment : Thanks . Few more observations : Comment : Checkout out the code . make compiles an executor scheduler both helloworld and minimesos-cli images . Based on my code study i am a java beginner minimesos-cli jar which is an executable-jar is a command-line interface to minimesos jar and accordingly has a void main . But I am confused as I think minimesos-cli is not used when doing minimesos up . It instead uses minimesos by doing its image pull first as that image is not built by make but just the jar . So how does minimesos run on its own I couldn t find any main function in there or some config that specifies an entry .", "Question : I was able to setup the minimesos cluster on my laptop and also could deploy a small command-line utility .

Would really appreciate if I could get to know what the aforementioned command does that results into 4 containers 1 master 1 slave 1 zk 1 marathon running on my laptop . .. . Answer : Every minimesos command runs as a short lived container whose image is containersol minimesos . When you run minimesos up it launches containersol minimesos with up as the argument . It then launches a cluster by starting other containers like containersol mesos-agent and containersol mesos-master . After the cluster is up the containersol minimesos container exists and is removed . We have separated cli and minimesos core as a refactoring to prepare for the upcoming API module . We are creating an API to support clients for different programming language . The first client will be a Golang client . In this new setup minimesos will run launch a long running API server and any minimesos cli commands call the API . The clients will also launch the API server and call the API .", "Question : I m trying to launch the kafka-mesos framework scheduler using the docker-container as prescribed at https : github.com mesos kafka tree master src docker running-image-in-marathon using the Marathon implementation running in minimesos I would like to add a minimesos tag but don t have the points .

The GUI shows that no tasks have been created . I do have ten mesosphere inky docker tasks running alongside the attempted Kafka deployment . This may be a configuration issue specific to the Kafka docker image . I just don t know the best way to debug it . Perhaps a case of increasing the log levels in a config file . It may be an environment variable or network setting . I m digging into it and will update my progress but any suggestions would be appreciated . thanks Comment : perhaps i should add that the Docker repository used for the mesos-kafka image is public . The image was built and pushed to DockerHub according to the instructions at github.com mesos kafka tree master src https : github.com mesos kafka tree master src docker running-image-in-marathon . Comment : there is also a docker commandline to run kafka-mesos according to the instructions : docker run -it -p 7000 : 7000 --add-host master : 192.168.99.100 batwicket kafka-mesos . kafka-mesos.sh scheduler --master master : 5050 --zk master : 2181 --api http : accessible-ip : 7000 --storage zk : kafka-mesos but get an error : 2016-01-06 20 : 40 : 33 448 main-SendThread master : 2181 WARN org.apache.zookeeper.ClientCnxn - Session 0x0 for server null unexpected error closing socket connection and attempting reconnect I believe the zookeeper config is different for minimesos .

The conflicting constraints are : field : hostname operator : LIKE value : master The hostname in the offer is 0f366bef3c2a so mesos-kafka appears to expect a name resolution that isn t present in the minimesos runtime environment . Comment : it would seem to be a problem with the kafka-mesos JSON file . The resource on offer is the id associated with one of the mesos slaves . If i remove the constraint line in the JSON file it launches . .. . Answer : Thanks for trying this out I am looking into this and you can follow progress on this issue at https : github.com ContainerSolutions minimesos issues 188 and https : github.com mesos kafka issues 172 Comment : It would be great if you could update this answer at some point in the future when the issue is completed . Just for the benefit of people who find this question on SO : Comment : will do. . I think it s just a question of when they get time to implement the feature or find suggest how to properly set LIBPROCESS IP . The minimesos project is essentially a shell on top of docker to start stop master slave marathon zookeeper containers in a batch .

I created the HCatalog table manually and all the correct fields exists and are of the correct type . The strange thing is that if I do dump data in Pig I get no output . If I illustrate data I see pieces of my data in the log followed by large blank areas followed by more data and so on . What am I missing here I d really like to take this messy XML file and get a neat table in HCatalog . Again I get the results I m looking for when running the local script on my machine but when I run the second version designed for storing the output into the posts table 1 HCatalog table I get a success message but an empty table . Alternatively if I can just get the output on my local machine as a comma-delimited file I can use that file and have HCatalog automatically load the data in the Hue interface . As of now the output is space-delimited which is problematic in Hue because the titles of posts contain spaces . Thanks in advance This has me stumped . .. . Answer : I found the issue . I created the HCatalog table manually and had used all of the default options including the delimiter which was set to A 100 . My output had columns separated by Tab spaces t so when the table received the data it found no A delimiter and stored an empty dataset .

Loading with HCatLoader works fine and dump explain confirm that my data and schema are as expected . When I try to write with HCatStorer however I have problems .

This works in the same environment if the table location is in HDFS instead of S3 - for both external and internal tables and from either Hive or Pig .

Answer : I think there is a issue when you write to S3 from pig using HCatalog . Since the final output data is being written to an temporary file and is never being copied moved to the original location . This weird behavior is encountered only on S3 .

Sorry i understand this question is a big vague and foggy but any help would be appreciated . .. . Answer : You need to get an instance of a Prolog engine and execute any prolog command . I suppose you will have the prolog database set up in advance and you can create the prolog command that will evaluate to true when a username password pair authenticates . Calling this from Java is then easy . You obtain a Prolog Engine implementation say SWISubprocessEngine http : www.declarativa.com interprolog htmldocs com declarativa interprolog SWISubprocessEngine.html and execute your prolog command with the command method . This article How can I make a Java program that calls Prolog http : www.declarativa.com interprolog faq.htm trying 20Prolog will be most helpful . Comment : I see Thanks for the reply..In think database will I have a pair such as hasaccess tom 123 where tom is the user and 123 is the password Comment : @keval That is a start yes . With a set of clauses like that you can quite simply query for a given username and password . Comment : Thank you very much . I m using XSBSubprocessEngine say if my database : access.pl had : hasAccess tom 123 how would i pass information from two string variables in java to pl to check the db Im quite new to prolog so im trying my hardest . thanks Comment : also how would you make java prolog aware of where the database is Comment : It depends . If you want to store the database in a traditional relational-database then I would use Java to create the clauses and have the prolog engine initialized with the data at application startup . Otherwise you can use something like consultFromPackage filename MyClass.class to load some prolog data from a file . So when the application starts the engine is told where to find the data that prolog will use . When you query from Java it uses the data from the file .", "Question : I am currently using interprolog - which is basically java with a prolog backend allowing both java and prolog calls from each other respectively .

So I suppose your LoginHandler class is in the default package and that is tripping this code up Try putting it in a package i.e . add package blah to the top of it and move it to a directory with that name . It does this because it assumes the userlist.pl is actually in the same location as your code and it s trying to use the package name to find the location your code was loaded from .

Answer : SmartCafe Expert 3.2 72k http : www.smartcardfocus.com shop ilp id 521 smartcafe-expert-3-2-72k p index.shtml is a simple regular Java Card and does not contain SIM Toolkit APIs inside . So it can t install those applets that used SIM Toolkit APIs . In the loading process the OPEN on the card is trying to make a link between your applet and the used libraries . As it can t find SIM Toolkit library there it returns this error . Comment : I had a sneaking suspicion as much . Time to go shopping again but I appreciate the answer . Do you have any words of wisdom on knowing which Java Cards will support STK APIs e.g . if it says Java card and SIM in the description http : www.smartcardfocus.com shop ilp id 776 smartcafe-expert-6-0-80k-sim p index.shtml is there a good chance it will support Java Card applets and STK APIs", "Question : I try to develop a Sim Application Toolkit Applet. .

Comment : As far as I know you CAN T run SIM applets in Eclipse IDE without any simulator . You need to use a SIM card simulator or try to run it on a real SIM card . For uploading and installing your applets first of all you need to convert your applet to CAP file . You need to work with converter tool in Java Card development kit . instead of that you can simply use Eclipse-JCDE plugin to convert your applets . After converting you need to upload this CAP file on the SIM card . You can use some already-written open-source tools . GlobalPlatformPro is one of them . Google it Comment : Thank you for response I have a real SIM card and a reader i think i can load my applet into this sim card.. . But I think that I should add the JCOP plug-in to eclipse in order to get the .cap file . i cant find the package JCOP in internet i wonder if it is availble in free do you have an idea Comment : No you can t find a free version of it . But you can use Eclipse-JCDE plugin instead . download here : sourceforge.net projects eclipse-jcde files http : sourceforge.net projects eclipse-jcde files I don t have any idea that you can use it for convert applets that contain SIM APIs or not but I m sure that it is sufficient for converting Java Card applets to CAP files Comment : I added Eclipse JCDE plugin and it s work i can now create applet convert it to a .cap file and give it an AID ... . .. . Answer : You can t run SIM applets in Eclipse IDE without using a simulator and you need to use a SIM card simulator It can be a plugin for your IDE also or try to run your applet on a real SIM card . Moreover for uploading and installing your applets first of all you need to convert that program to a CAP file . There is a tool in Java Card development kit named converter that you can use it to convert applets to CAP files . Instead of using converter tool directly you can simply use Eclipse-JCDE http : sourceforge.net projects eclipse-jcde files plugin to work with this tool and convert your applets . After converting you need to upload this CAP file on the SIM card . You can use some already-written open-source tools to aim this goal . GlobalPlatformPro https : github.com martinpaljak GlobalPlatformPro is well-documented one . Note that : I m afraid if the Java Card Development kit is able to convert applets with proprietary SIM APIs to CAP files . but for applets that contains only Java Card API you can use it simply . Comment : Exactly i am having problems with my applet because of the SIM APIs any idea to resolve this problem Comment : @DGz Unfortunately no idea . where did you download the SIM APIs I think in some ETSI packages you can find useful tools . There was some question in this community useful for you .

Following this post http : stackoverflow.com questions 30325663 send-apdu-commands-to-usim-sim-card-in-android thanks to @vojta and @jean and SEEK https : github.com seek-for-android pool wiki UsingSmartCardAPI I would like to build my app using RIL Radio Interface Layer . Where can I get those libs The only ones I can get is for Nexus - here https : developers.google.com android nexus drivers . If I understand it well I will have a different .apk file for each mobile manufacturer . Am I right If yes is there any other way to communicate from Android to SIM applet apart from SEEK If I cannot avoid that I really think SEEK is the best or the only way to communicate with my SIM applet can someone share a step-by-step manual for building such an example APK application including communication with the applet .. . Answer : You cannot simply add that functionality RIL extensions to access a UICC SIM-based secure element to an app . Instead the mobile phone has to support this functionality . You typically cannot replace the radio interface library telephony framework on the fly you could probably do such kind of patching on rooted devices but still that s not something you would typically integrate in your app . However many current Android devices come with a ready-made SEEK implementation that could be used to access the UICC SIM card many devices by Samsung e.g . GS3 and later Sony HTC and Motorola . When it comes to Nexus devices the Nexus 6 is the first that supports SEEK . On devices that support SEEK i.e . that come with the SEEK smartcard service preinstalled you can use SEEK by linking your application to the SEEK SDK-addon http : seek-for-android.googlecode.com svn-trunk repository 19 addon.xml or by integrating the Open Mobile API directly either as a library-project or by adding the source files into your application you can find the latest version here https : github.com seek-for-android platform packages apps SmartCardService tree android-5.0.0 r3-scapi openmobileapi src org simalliance openmobileapi . You can find a sample application for access to smartcard applications through SEEK here : https : github.com seek-for-android open-mobile-api-sample", "Question : I would like to programmatically access an STK SIM Application Toolkit application without using my handset .

Is there any free implementation I have found the ETSI - 3GPP http : www.3gpp.org DynaReport 0319.htm a zip file with some code and libraries but I don t know if this would be enough . Do I generate the cap jar file from the code there Thanks .. . Answer : The files from 3GPP should be enough to complement the Javacard libraries that you ve downloaded from Oracle . Just as you need to know the Javacard version of your card you need to know also what version of SIM API the card support . Check it againsts the 3GPP TS 03.19 that you ve mentioned or you may also check for 3GPP TS 43.019 http : www.3gpp.org DynaReport 43019.htm . Download the correct version .

What we need to do is to convert class files to CAP file . JCDK is able to convert any APIs . Just make sure that you put the JAR and the EXPort files of the API . Comment : I must add the JAR files to my project . but what about the Exp files where I must put them I know that I must put the in the directory of other export files but where are those Comment : You can add it under java card kit-2 2 2 api export files along with com java javacard and javacardx directory .", "Question : I would like to programmatically access an STK SIM Application Toolkit application without using my handset .

Since that is a closely held secret of the device vendor you can t do that . You might be able to re-sign the whole thing though . As you are finding it s hard to make just a little change in Android - it s really intended with the idea that 3rd parties will stick to the application APIs and vendors will do a full system build from source .

The source content is in Markdown and contains a number of tables . I ve tried generating output with four or five different Pelican themes but the tables never have any visible borders . All the table content is arranged neatly in rows and columns but there are no cell borders or outside borders . Is there a specific reason for this Am I intended to modify the CSS manually It seems unlikely that all of the theme authors would make this same design decision . Example of one of my tables : Comment : That s most likely your browsers default styles . Chrome doesn t display table borders by default anymore for example .. . Answer : Is the HTML attribute border set If so it is most likely the decision of your browser how to render the table . I checked a few themes myself just by having a quick glance at the CSS code no guarantee for correctness : .. . .. . I can imagine that depending on the contents the justification and other formatting aspects make having borders on all tables inappropriate . Consequently I can understand the design decision to per default disable table borders and let the user of the theme customize the behavior if required . On my website I use tables for many different things . Often especially when blocks like images or syntactically highlighted areas are included borders would make the table look weird . As of this I second this design decision . But still what if one wants borders on some tables Case-dependent styling using CSS is easy to achieve if special HTML classes can be specified in the article source file . Unfortunately python-markdown or markdown in general does not support this kind of feature . At least this is what a short Google research revealed . Maybe there is a python-markdown extension I did not recognize . . Another way would be to use another markup language . reStructuredText is more complex but also much more extensible in comparison to markdown . The table http : docutils.sourceforge.net docs ref rst directives.html tables directive natively supports the specification of HTML classes . I use reStructuredText myself and like the high amount of flexibility the markup language introduces . You could also let javascript do the job and set HTML classes likewise styling depending on the table contents . However I would not consider this a good solution as you create a dependency on javascript for the appearance of a static website . I hope this helps you : .. . .. . tl dr .. . .. .

Any help would be appreciated . .. . Answer : Make sure you are using attach and not filename . Also if you have energy.png in the same folder as blogpost.md then attach will work . With your example you must have energy.png in the images subfolder . The documentation states that you should be careful of images being attached to multiple pages . If energy.png is only being attached -ed to blogpost.md then it will get published alongside the resulting HTML file . Otherwise it may be moved to a place were otherblogpost.md won t expect it to be unless all files are in the same directory which is not going to happen in your case where the resulting html files are in the date subfolders .

Answer : I just took a look at the source code https : github.com if1live pelican-jsfiddle for that plugin and it appears that Markdown is not supported . In other words the plugin authors only included support for ReST but not Markdown . And understandably so . They used a ReST directive and Markdown has not concept of directives or anything like them . That said Pelican uses Python-Markdown for parsing Markdown which has a very extensive Extension API https : pythonhosted.org Markdown extensions api.html . I did a quick search and don t see that anyone has created a jsfiddle extension for Python-Markdown yet but it wouldn t be terribly difficult to do see a tutorial here https : github.com waylan Python-Markdown wiki Tutorial : -Writing-Extensions-for-Python-Markdown . If you are looking for any pre-existing syntax I did find this http : www.codeproject.com Articles 507944 Extending-Markdown-MarkdownSharp-for-jsFiddle-embe.aspx which was part of a different Markdown implementation . It uses FIDDLEID borrowing from the image syntax using a instead of . Of course as that is non-standard Markdown it will not work if you migrate to another Markdown implementation in the future . A common solution to that problem in the Markdown world it to implement something inside an HTML comment instead of some special custom syntax . Perhaps -- fiddle : FIDDLEID -- . Then if migrated to another Markdown implementation the comment would simply be ignored and nothing would break . Either way actually building such an extension is beyond the scope of this answer . Of course if you attempt to build it and run into issues those specific issues may be separate questions of their own .

Links to internal content in Pelican use the syntax filename path to file .

I m hoping that there is a simple function I could write which would allow org-mode to follow such a link and open the relevant file without compromising Pelican s use of the internal link syntax .

The trouble with this is that the link without filename will have to be an absolute link while the link with filename would not .

Note that Users Username bin pelican content has been replaced by filename . Comment : I edited the response to use a relative-path . Is that what you need Comment : The pelican links open in org-mode properly but don t give the right path in the html document . Am I right that this proposal assumes that I m using org to convert the files to html If so that might be a problem since I ve been letting pelican with org pandoc as a plugin do the conversion work . Comment : You are right I did assume you were using orgmode to generate the html . I don t know how org-pandoc works or if it can be customized .

Thank you .. . Answer : Before I start let me state that I don t know the specific of the dict-protocol . I doubt that you ll be able to create a request that only delivers the text . The information you wish to discard looks like status information and is therefore useful . The way I d handle this is as follows : .. . .. . 1 . Read the curl response data into an array so that each line is an separate entry in the array . You could use explode and split at the new line character n to do this . 2 . Iterate the array EG for response as responseLine .. . 3 . perform a regex or some other form of pattern-matching on responseLine to find the definition . It looks like the actual text is the only responseLine which doesn t start with a number . You may want to check what characterset the dict-protocol uses .

When i do search insert select queries in the DB i need to scan the hole table cause some stuff could be in ROW 1 and the other in ROW 1000000000000 .

It seems everyone uses HBase instead however Hypertable claims to be much faster . Comment : Tip : If you can find very little information online I wouldn t recommend using it for production just yet.. . Comment : Not true at all . The more Enterprise something is the less usage it will get from normal users and thus the less you will find about it online . Comment : The causal relationship between product being enterprise class and therefore lacking online documentation is not as straightforward . Consider IBM db2 or IBM Websphere - both have extensive documentation available online . On the other hand you have IBM zOS - it is certainly well documented but little of it is available online . Reason being is that zOS architecture has little competition being a closely-guarded system . So I think the criteria is - if product is unique and the ecosystem is closed - you ll see no publicly available documentation . Things are different for OSS .

The sad thing is that there is no much support community around hypertable .", "Question : i want to design a users table with the following fields in hypertable database : .. . .. . now the rowkey is the id of the user and i refer to this id a lot of stuff that belong to user i understand that in hypertable the only auto primary-key options is guid the reason i won t use the username as the rowkey is because the username can be changed if changed occurs i will have to update a lot of stuff in the entire database . same role append also to the email field . now user can login with his username or with his email . so i will need to retrieve entire row by email or by username . can you help me design this table thanks . Comment : Why don t you use e-mail as the rowkey That would be ideal for this - especially if you have to look up by e-mail . Comment : if the user will-change it email then i will need to update all the references in all the table . i need in the key some value that will not change . i will have the same amount of quires for the id and email and username Comment : Ah I see will only the e-mail change or the username as well If either or both of these can change you will need to use a index - either in HBase or external . Comment : the email and the username can change . in hypertable they have the build-in indexes . i don t know if hbase also have build-in indexes .. . Answer : If you download hypertable sources or browse the sources online then you will find a PHP example project which implements a twitter-like microblogging site . And basically it implements the same user table as you asked for with one difference : it uses the username as the row-key . But you can easily change this and use the GUID instead . Although from a user s perspective i think you very rarely change the username and i do not know any webpage that offers such a function . Changing email-address or location is of course necessary . Here is the script which generates the database look for the profile table : https : github.com cruppstahl hypertable blob v0.9.5 examples php microblog setup.hql Comment : my problem with the twitter example is that the user login with it email or with it username so i need to query by email or username . and not by the guid rowkey . hypertable is column oriented database so for query on two columns i think the best way is to use the column qualifier feature for the username and email columns fields for example : login : username login : email and then make a query like select login from accounts where login username email and then i will find the rowkey and query again by rowkey . Comment : If you use username or email as a row-key then your only problem is that you have to copy all those rows as soon as the user changes its username or email . Other than that there s no disadvantage . But if you want to use the GUID then you can simply have one column family which maps usernames or emails to GUIDs i.e . the cell value contains the username and the row-key is the GUID . Then run select guid from accounts where guid email@blah.com and fetch the row-key . Make sure to create a secondary index on the guid column family . You would not even need column qualifiers for that .", "Question : Ok I have some trouble getting through HyperTable http : hypertable.com Going through the docs and other stuff I am still not very confident at why I can t use the .. . .. .

Answer : You can control the RangeServer s memory consumption with the configuration option Hypertable.RangeServer.MemoryLimit.Percentage . The default is 60 .

Main problem I have is how do I store data that you cant represent as key-value . For example lets say I want to track user reviews I may simply imitate relational databases generate new review key store all data I need and then for for product X store keys to all reviews in json format to x.reviews .. . .. . The other thing I came up with is simply have x.reviewKeys and then for each generated review push new key as a new version of that cell assuming that I can store infinite number of versions of the same cell . Second approach seems much more appropriate to me as I leave to database all the work I would implement in code . Does anyone know how to handle this problem or even better how does google handles this with their bigtable .. . Answer : This few hours of searching for anything that might result in understanding Hypertable database-design is definitely not enough but here is starting point if someone runs to this over google .. . .. . Now far as I understood it so far is that you can define column family say reviews and each column family can have infinite number of keys for example if you try to store user data you would probably write something like this .. . .. . userKey : info and have multiple properties like name address email .. . and you would be able to access that info simply by defining key to that entry so for example to get user address you would use userKey : info : address as key .. . .. . One thing that makes column families different if I understood it well is that you can get all that keys in column family so for example if you specify userKey : info you would get userKey : info : name userKey : info : address userKey : info : email as result which means that to store all the reviews I mentioned in my question you would create new column family and store keys to all reviews and you would end up with something like this key : reviews : review ID which would return IDs if you ask it to return key : reviews of all reviews and than you would simply use that ID to get details about specific review . so basically just like you have properties name address email in column family info here you would use review ID as column property . Now to be at least partly sure I got It right I also checked out riak database-design key-value database unlike hypertable which is column database and seems like they have bucket as alternative to column family so this at lest seems to be right implementation .. . .. .

Answer : Hypertable does not support transactions and does not have any locking or read-modify-write operations .

It looks similar to when you attach a debugger in VS to a process where the source code is different than that of the executing binary . If I disable either PostSharp or Fody then debugging works immediately again . Is it possible to use both PostSharp and Fody in the same project Does this require special extra configuration Comment : Debugging with PostSharp should work .

Answer : So this really should be Several questions .. . .. . Does Fody leave any references in final assembly No Fody does not require any references not add any reference during ILWeaving . Nor does it require than any files be deployed to be used a runtime .. . .. . Does Fody leave any traces in final assembly Yes . Due to the nature of MSBuild and Visual studio it is very dificult to tell if an assembly has been changed as part of a build . As such Fody injects an internal interface named ProcessedByFody into your assembly . This allows Fody to avoid double processing of assemblies . https : github.com Fody Fody wiki TaskAddsAFlagInterface .. . .. . Do Fody addins leave any traces in final assembly Well the obvious answer to this one is Yes . All addins modify the target assembly in some way . Do Fody addins leave any references in final assembly This is optional and up to the creator of the addin . While many addins have a dll to reference this is usually just to provide metadata . The addin then removes the reference at compile-time . Meaning that it is not necessary to deploy that reference dll .

Answer : To sum up what I had hoped to do was find some option that would tell Fody.PropertyChanged to use a field other than IsChanged for the same purpose . For instance to use a field named IsDataChanged rather than IsChanged . This was because the database administrator had designed the entire database so that each table has a field named IsChanged that he wanted to use for his own purposes which are different than what is needed in the application . To skirt the issue the database administrator renamed his fields to IsDataChanged . By doing this he has a field to use as he needs which will not be automatically maintained by either Entity Framework or Fody.PropertyChanged .", "Question : I ve got a WPF application using Caliburn.Micro .

Updating A and AA works fine however B doesn t update automatically when first.A changes . Is there an easy and clean way to achieve such automatical updates using fody or do I have to create my own event to handle it .. . Answer : I am not familiar with Fody but I suspect it is because there is no setter on Second.B . Second should subscribe to changes in First and if First.A is the property being changed then that should use the private setter of B . .. . .. . Alternatively subscribe to First and then invoke B property changed event : Comment : Setter is not requiered to update the view . I added property AA in First which will update just fine when A changes . What I m asking for is Fody functionality to avoid creating manual subscribtions in Second .

In the case of being inside the owning class it is just automatically injected into the code : github.com Fody PropertyChanged https : github.com Fody PropertyChanged Comment : I ve seen that earlier however that doesn t solve my problem . Of course i could add an event and handle it in Second by setting B with a private setter to force an update but unfortunetelly that solution is not scaleable .

Have you looked into ReactiveUI It might offer something more elegant but still somewhat manual .

PropertyChanged should be raised in case another value is assigned to the property in your case another list to the Others property .

Answer : FallbackValue doesn t always work i.e . if your designer is actually bound to design-time data and FallbackValue actually modifies run-time behaviour of the binding which may be less than desirable in many situations .

It appears to work fantastically but it is doing strange things to our FxCop http : msdn.microsoft.com en-us library bb429476 28v vs.80 29.aspx analysis built into visual-studio . We have CA1062 http : msdn.microsoft.com en-us library ms182182.aspx and CA2214 http : msdn.microsoft.com en-us library ms182331.aspx enabled : The former validates arguments of public methods and the latter checks for calls to overridable methods in constructors . The second one we have figured out is due to the fact that we are also using Caliburn.Micro which supplies a method called NotifyOfPropertyChanged which is virtual . This is a simple fix of changing the method to not be virtual . The first issue is much harder and seemingly random . We have been hard core about validating our arguments from the get go and did not have any FxCop analysis errors before Fody but when I added it through NuGet FxCop was seeing changes in places that shouldn t have any weaved code for property changed .

I don t see any info in the documentation page on it is there a hidden property in the FodyWeavers.xml .. . Answer : This question was also asked here https : github.com Fody PropertyChanged issues 5 and from that issue.. . .. . .. . PropertyChanged.Fody makes the assumption that if you implement INotifyPropertyChanged then you would most likely want to notify for most if not all properties . If you wish to exclude them which should be the exception not the rule then you can add a DoNotNotifyAttribute to a class or a property . see here for more details https : github.com Fody PropertyChanged wiki Attributes Comment : That s a really bad assumption Comment : @EugeneStrizhok why where is no perf overhead Comment : Well . I may have overreacted . : But I see a rather frequent case-when automatic notification is introduced to an existing project and one may not wish to go through all types implementing INotifyPropertyChange in order to adapt them . In this case it will be desirable to be to set Fody.PropertyChanged behavior in a such way that it will only weave explicitly marked classes . Comment : As far I as remember NotifyPropertyWeaver had such an option . Comment : @EugeneStrizhok correct NotifyPropertyWeaver had such an option . but that that a legacy option due to the evolution of NPW . it was never a conscience design decision . so in the reboot with PropertyChanged.Fody it was removed .

I have added the ImplementPropertyChanged directive before the class declaration : .. . .. . I have the following two properties in the class that I bind View elements to : .. . .. . One View element s Visibility property is bound to the View Model s ShowDetailsVideo property . Another View element s Visibility property is bound to the View Model s ShowMainScreen property . At runtime both property getters are accessed indicating that the pair of bound View elements are accessing the properties at least once . Also the two View elements do have the proper Visibility states . However if I change the ShowDetailsVideo property at runtime the setters are accessed but not the getters indicating the wiring between the properties and the view element properties isn t working despite my use of the Fody PropetyChanged package . The property access behavior is the same as-if the Fody package wasn t even there .

But you can achieve what you want with Converter . In one case I used one to set the width of a textbox based on the amount of characters typed . What I m saying is give it a try . Comment : @Tico Are you saying that I should implement a Converter that converts a Visibility to a Visibility That s a non-operation . Comment : On second thoughts you re right . Sorry to waste your time . .. . Answer : I am adding this answer because this problem cost me several hours to hunt down and fix . I am marking the answer as community wiki because I am not seeking credit for it only to save someone else the trouble I went through diagnosing it . Below is the corrected View Model code to make the property changed notifications work properly . The View was not updating when bindable properties in the View Model were changed because I was not calling the base SetProperty method in the property setter instead I was only doing a direct assignment so a property changed notification was not triggered . You can see this in the property setter in my original post . Simply adding the SetProperty call fixed everything . So if your View Model class descends from a class like BindableBase see below you do not need the Fody PropertyChanged plugin at all but make sure you are calling SetProperty in your property setters instead of doing a direct assignment to the data member backing the property .

I prefer QQmlApplicationEngine though . This class combines a QQmlEngine and QQmlComponent to provide a convenient way to load a single QML file . So you would have fewer lines of codes if you have the opportunity of using QQmlApplicationEngine . Example : .. . .. . We could also use QQuickView .

Comment : I agree with @Mitch the Qt documentation is the best docs I ve ever seen so if you found that not clear I think you won t find any help here .

This is written in the documentation http : doc.qt.io qt-5 qml-qtqml-component.html details : .. . .. . Notice that while a Rectangle by itself would be automatically rendered and displayed this is not the case for the above rectangle because it is defined inside a Component . The component encapsulates the QML types within as-if they were defined in a separate QML file and is not loaded until requested in this case by the two Loader objects . Because Component is not derived from Item you cannot anchor anything to it . When declaring delegates Component is used because there are several delegate items that must be created .

Such a component is available as a property usually called contentItem http : doc.qt.io qt-5 qml-qtquick-controls-groupbox.html contentItem-prop . If you write an example which prints such a property you ll see that contentItem is the parent you are searching for : .. . .. . Output : .. . .. . qml : parent QQuickItem QML 26 0x1411fc0 container contentItem QQuickItem QML 26 0x1411fc0 container Comment : Thanks If I want to refer to GroupBox from MouseArea I should only use GroupBox s id should I Comment : Yeah the id not the parent property .", "Question : I have a QML ListView where the delegate loads it s component from another file . When clicking on an delegate item I want to update ListView . CurrentIndex and highlight the selected item . It works when I explicitly set the id of the ListView .

Here is the Code : .. . .. . main.qml .. . .. . Contact.qml Component used by delegate .. . .. . Any help is really appreciated .. . Answer : There are two problems here : .. . .. . You need to qualify ListView s attached-properties with the name of the item from which they re accessed . The currentIndex property is a property of the ListView item type http : doc.qt.io qt-5 qml-qtquick-listview.html currentIndex-prop not the attached property object http : doc.qt.io qt-5 qml-qtquick-listview.html properties . To fix them both first change this : .. . .. . to this : .. . .. . And then give your delegate an id : .. . .. . This is demonstrated in part by the Example Usage http : doc.qt.io qt-5 qml-qtquick-listview.html example-usage section of the documentation : .. . .. . ListView attaches a number of properties to the root item of the delegate for example ListView : isCurrentItem . In the following example the root delegate item can access this attached property directly as ListView.isCurrentItem while the child contactInfo object must refer to this property as wrapper.ListView.isCurrentItem .", "Question : Hi Everyone i am new to QT and i am having trouble loading one qml through another qml Basically i have created a qml MyTabView MyTabView.qml .. . .. . and i am trying to show it through another qml main.qml which is in the same directory .. . .. . but when i try to run my project i get this error .. . .. .

Please note that i have M Caps in MyTabView.qml and that MyTabView.qml and main.qml are in the same directory . Can someone point me what mistake i am doing One thing i want to point is that when i replace all the code of MyTabView.qml instead of MyTabView inside main.qml the program does not give any error and runs correctly . Thanks in advance Comment : You have called your own class TabView whilst using Qt s TabView simultaneously . Change your class name in QML the class name is the name of the QML definition file . Comment : I have changed the name of my xml file to MyTabView.xml and is calling MyTabView in the main.xml but i get the same error MyTabView is not a type .. . Answer : Have you added the file to your Resources Adding your MyTabView.qml to your project in the same directory of main.qml is not sufficient . You have to put your QML file in the Resources probably main.qrc qml in order to have it deployed . The editor of Qt Creator does not need this inclusion in order to find your type therefore it displays no error . Nota : when you write xml I assume you mean qml including the name of the files .", "Question : I m using Qt 5.5 to create a small app . In the app I m manually creating a component like so : .. . .. . My .qrc file IS included in the .pro file like so : .. . .. . All works well when I run from Qt creator . However when I deploy the app using the macdeployqt tool and try to run the app I get that assert hit . Sure enough I tried to put a loop around the .isReady and it will hang forever . What is the proper way for doing this My qml component is working fine when in the Qt creator so why does it fail in deployment Thanks Comment : Can you post more code Mabe you can test if is loading with isLoading if the assert hits Comment : This was actually the same issue as my other question on the QmlComponent . I wasn t aware you need to pass -qmldir path to qml files to the macdeployqt tool . .. . Answer : This turned out to be simple . You need to pass -qmldir path to your qml files to macdeployqt . It is actually required if you have QML files but I somehow didn t see it in the documentation .", "Question : I came across a weird problem when designing my application in QML . The following code works : .. . .. . I have a bunch of functions properties and loaders in this item delegate which is an Item object . Problems arise when I try to reuse this delegate in a ListView . I can t reference it like this : .. . .. . This is because itemDelegate is a Component : .. . .. . http : qt-project.org doc qt-5 qml-qtquick-controls-tableview.html itemDelegate-prop .. . .. . So QML can convert an Item to Component when it s embedded but not when it s referenced . And I can t make it a component since components can t have functions loaders properties etc . How can I reuse my delegate .. . Answer : Solved by wrapping the item inside the component : Comment : I m also struggling with this issue but your code is not working for me because I actually have a list of Component s . In my case I have a PageIndicator with a list of Image type components inside and I m trying to assign an element of that list to the delegate property .

What is the preferred type to use as a container for several widgets Can it be replacable by Rectangle For example what is the difference in the following declarations : .. . .. . and .. . .. . Why do we usually use Component when declaring a delegate Comment : What don t you understand about the docs They can t be improved if you don t say why they aren t clear . I think that they are quite clear and any answer you get here will most likely be a re-wording of what already exists . Comment : I agree with @Mitch the Qt documentation is the best docs I ve ever seen so if you found that not clear I think you won t find any help here . Comment : Added some example to the question description .. . Answer : A Component is both a concept and a thing in QML . An Item is a visual thing defined in QtQuick module which is usable in QML . Those two things are conceptually different . As in QML concept all reusable thing is called components . You can define a component in multiple ways but one easy way is to create a .qml file and name it as you name your component . i.e : Button.qml or Swithc.qml . When QML engine load that file you can use that as buttons or switches . Another way to define a component is to use Component in a qml file . This allows you to define a new component inline . A component defined inline does not work after explicitly loaded by a loader http : doc.qt.io qt-5 qml-qtquick-loader.html . An Item on the other hand is a simple type defined in QtQuick module . I think it is OK to call an Item a Component even though an Item is not technically inherited from Component . Or more precisely you could say your custom component is based on an Item if your .qml has Item as a root type .", "Question : I have a qml file with Rectangle . I would like to trigger the onClicked from C++ back-end . So How can I get access of QML component reference in C++ Qt backend .. . Answer : You should use QObject : : findChild to locate the object and simply invoke the signal as you would a nominal method . But there is a catch as QQuickRectangle itself is a private class so it is not directly available for use in the C++ API . Also it doesn t really have a clicked signal not unless you implemented one yourself . And if you did it won t be part of the C++ interface . Also there is no onClicked signal the signal is clicked and onClicked : is the handler hook . However you can still emit it using the Qt meta system just use : .. . .. . It will work even if the signal is implemented on the QML side it will work even without casting to the concrete C++ type . Now if your object is not directly in the root object tree you will not be able to find it and will have no choice but to pass a reference to it from the QML side to a C++ slot or invokable function . Comment : I have tried to call the slot of QML onPropertyNameChanged from invokeMethod but it is not handling I think signal can only be invoked . Comment : @Ashif - there is no such object onSignalName - this is just an assist provided to make declarative connections it cannot be invoked .", "Question : When I use Qt.createComponent to create component dynamically the stutas is always Component.error but I cannot understand the reason . I used it like that : .. . .. . If the MyPage.qml does not exist in the qrc file the error is .. . .. . qrc : MyPage.qml : -1 File not found .. . .. . If I set the full path of MyPage.qml I get a Network error . When I add the SeriesSelectionPage.qml file to the resource file it works . But it shouldn t be dynamic I just want to find a QML file and load it dynamically when the application executes so that the application can load different QML according to user operations . Anyone knows how to do that I m going crazy . .. . Answer : Qt.createComponent http : doc.qt.io qt-5 qml-qtqml-qt.html createComponent-method takes a url as its first argument . From the url documentation http : doc.qt.io qt-5 qml-url.html : .. . .. . The url type refers to a resource locator like a file name for example . It can be either absolute e.g . http : qt-project.org or relative e.g . pics logo.png . A relative URL is resolved relative to the URL of the containing component . So as long as you re using relative URLs from within a file that is loaded from a QRC file you ll need to use the qrc scheme : Comment : It will be better just add the QML file into resources and use qrc : protocol in URL . Comment : I was under the impression that OP wanted the end user to be able to choose a QML file.. . guess I misread .

Answer : NetOffice http : netoffice.codeplex.com is a great set of version-independent interop assemblies for Office . This is all you need to make add-ins using SharpDevelop and the project has a bunch of tutorials and samples too including some for Outlook . If you re making an add-in for Excel using Excel-DNA http : exceldna.codeplex.com which you need to expose user-defined worksheet functions from .NET NetOffice still gives you a complementary set of libraries for accessing the Excel COM automation interfaces from your Excel-DNA add-in so they work together well . For both NetOffice and Excel-DNA you ll also be able to use the free Visual Studio Express editions with some small tricks needed to get debugging working . Visual Studio Express does not include VSTO at all . SharpDevelop also has-many more features than the Express editions like built-in refactoring and VB.NET - C translation tools so there are good reasons to prefer SharpDevelop as your free IDE . Comment : NetOffice looks fantastic . Wish I had seen this before starting with Visual STudio but still not too late to switch to Sharp Develop : D Comment : NetOffice is just a collection of .NET libraries you use instead of the special VSTO libraries or the Office interop assemblies .

Answer : SharpDevelop does not support 64-bit debugging . Did you try using the VS community edition to open your existing project file I don t see a reason why it would refuse to build debug a project that works in SharpDevelop . If VS complains about invalid project types try removing the ProjectTypeGuids element from the project file . These GUIDs just tell VS which plugins should be used to open the project they usually don t have any effect on simple building debugging . Comment : You are absolutely right .

The fact that your code builds it doesnt mean its good : There are still some things that can go wrong in the run time .

Answer : It looks like a bug in SharpDevelop 5.1 being unable to resolve the OxyPlot assemblies . It looks like SharpDevelop 4.4 does not have the same problem and can open the form in the designer . As a workaround for SharpDevelop 5.1 you can copy the OxyPlot.dll and OxyPlot.WindowsForms.dll files into C : Program Files x86 SharpDevelop 5.1 bin .. . .. .

Answer : Neither SharpDevelop nor Visual Studio have an Ellipse control for Windows Forms in the Toolbox . The tutorial is for WPF and Visual Studio does have an Ellipse control for WPF but SharpDevelop does not have one that you can drag from the Toolbox .

I recently found out visual-studio is free for students anyway so I ll be using that from now on . However while using SharpDevelop I noticed that when you create a Label via the designer the property that controls the text in that Label is not called Text like it is in visual-studio but I assumed it would be since they are both c . My understanding is that the designer is just a GUI version of XML code and that it creates the XML code for you . If you navigate to that XML file I thought maybe the name of that property was arbitrary and you could change it there but that didn t work either . Any thoughts Comment : Actually Visual Studio Community which have almost all the functionality of VS Pro is free even for small company . .. . Answer : It s correct that they are both c but probably one is WinForms and another is WPF https : en.wikipedia.org wiki Windows Presentation Foundation . The designer use XAML https : msdn.microsoft.com en-us library cc295302.aspx that is an XML-based markup language developed by Microsoft . Instead of a Text property the Label has a Content property The reason for that is that the Label can host any kind of control directly inside of it instead of just text .

There is a checkbox in Tools - Options - Coding - C - Code inspection but it is read-only . .. . Answer : It looks like it is not currently possible to disable code-analysis . Looking at the SharpDevelop source code that check box does not do anything even if it was enabled . So your options are : .. . .. . 1 . Disable the C addin . Which will break C completely . 2 .

I am currently not in a position to use Sharpdevelop 4 it would be better if I can use that new code editor in old Sharpdevelop 3.x . Can anyone please shed some light on it Thanks in advance . .. . Answer : Most of SharpDevelop 3.x is hard-coded to use ICSharpCode.TextEditor . You can use an AddIn to replace the text-editor see samples DisplayBinding AlternateEditor but you lose all of the following features : .. . .. . Code completion .. . Refactoring .. . Search + Replace .. . Forms designer .. . and some more.. . .. . .. . All of those features were rewritten to use the new text-editor interfaces in SharpDevelop 4 .

Comment : Can you please explain in details what you need to run in which linking function Comment : Btw angular.module app .directive myDar .. . will register myDar as snake-case in the html my-dar .. . my-dar .. . Answer : For this you will take advantage of the directive s controller . It will be a class defining a method to register nested controllers and another one for executing the desired command here .. . .layout .. . on this element and then on all of its children . This means that the outer directive is responsible for coordinating the creation of the layouts . The full example code is : .. . .. . Replace the line console.log PAYLOAD : + this . element.attr id with the actual code to run . See relevant fiddle : http : jsfiddle.net 8xSjZ .. . .. . If the outer directive was different than the current getting the parent controller would be as easy as requiring y . In this case it gives us the current controller therefore we have to loop e.parent ourselfes . Comment : Great answer . One question : how does the e.controller y work Does this directly call the constructor of the Controller class Comment : Hi thanks . Actually e.controller is an Angular extension to jqLite or jQuery . It is documented here https : docs.angularjs.org api ng function angular.element - look for jQuery jqLite Extras . What it does in short is that it finds an existing controller with the given name attached to the element . So it does not call the constructor it expects the controller to be already constructed and attached to the element . Comment : Thank you . Much appreciated . Comment : One more question : Consider I do not have nested a directive so I have something like div level 1 id a y followed by another div id other level 2 y . While processing the first div in the link function I would like to access the second div using angular.element div level 2 and subsequently the controller using .controller y . See this plunkr : plnkr.co edit oIpvQP http : plnkr.co edit oIpvQP . I get a JQLite exception Looking up elements via selectors is not supported by jqLite See : docs.angularjs.org api angular.element quot http : docs.angularjs.org api angular.element quot Comment : You would have to include jQuery for this so that Angular uses jQuery instead of jQlite . jQlite is an implementation of a cut-down version of the jQuery API .

Answer : Depending on the exact use-case a compile function might be a good fit . compile functions are executed before link functions and - what s more important - in reverse order . Meaning parent first . Another solution could be to execute the relevant code of your child directives using timeout .

The div widths work exactly as desired but the heights are always zero pixels unless I hardcode the height in the CSS e.g . Hardcoding the height is not an acceptable solution .

This renders the container and all its contents with zero width and height . This renders the container and all its contents filling the entire browser window overlaying the rest of the content .

Anyone else run into this or have any idea on how to fix it I m working on producing a fiddle but having some trouble . .. .

So I ll have to implement multiplication in ternary arithmetic . This is what I d like to avoid just for fun to find some tricky and fast way . Comment : @Stephen : Ah I see your point . .. . Answer : I think that everybody is missing something important . First compute a table in advance for each binary bit we need the representation in ternary . In MATLAB I d built it like this although every other step after that will be done purely by hand the computation is so easy . Now consider the binary number 011000101 which happens to be the decimal number 197 as we will find out later . Extract the ternary-representation for each binary bit from the table . I ll write out the corresponding rows . Now just sum . We get this representation in uncarried ternary . Yes those are not ternary numbers but they are almost in a valid base 3 representation . Now all you need to do is to do the carries . Start with the units digit . 5 is larger than 2 so subtract off the number of multiples of 3 and increment the second digit of the result as appropriate . The second digit is now a 2 a legal ternary digit so go on to the third digit . Do that carry too .. . .. . Finally yielding the now completely valid ternary number.. . Were my computations correct I ll let MATLAB make the final judgement for us : .. . .. . Have I pointed out just how trivial this operation was that I could do the conversion entirely by hand going essentially directly from binary to ternary at least once I had that initial table written down and stored Comment : I ll note that this approach works for essentially a direct conversion between any two number bases as long as you compute the appropriate table first . So if you wish to convert from base 3 to base 7 and do it more than once you can do it efficiently .", "Question : Does anybody know or may point to some source to read about a method or algorithm to convert a number represented in binary numeral system into the ternary one my particular case or universal algorithm for such conversions The solution I ve already implemented is to convert a number to decimal first and then convert it into required numeral system .

The following code is the wrong direction it is a conversion from ternary to binary based on the fact that 3 2 2 3 + 1 using only binary addition . Basically I m converting two ternary digits in three binary digits . From binary to ternary would be slightly more complicated as ternary addition and probably subtraction would be required working on that .

Answer : No you can t convert a base2 number to a base3 number without loading it into an integer . The reason is that 2 and 3 are coprime - they have no common factors . If you were working with base2 and base4 or even base6 and base9 then the set of integers up to the lowest common multiple of the two bases would be represented by two isomorphic sets . For example 13 base4 0111 base2 so converting 1313 base4 01110111 base2 - it s a find and replace operation . At least the solution that you have works and is relatively simple . If you need to improve performance then convert the entire base2 representation to an integer before starting the base3 conversion it means less modulus operations . The alternative would be process each character in the base2 number one by one in which case you ll be dividing by all the powers of 3 for each digit in the base2 representation .

Answer : There are some people here that have no idea what they are talking about . I first designed a 16-bit computer using binary then got to trying to do it with ternary . First to all that are saying the hardware is too difficult it is difficult to differentiate the values...well you re completely wrong I can make a not gate in ternary and I don t even need transistors only diodes which in case anyone here doesn t realize can be made smaller and more efficiently on a die . Secondly you need to realize that +1 and -1 are THE SAME THING one flows one way the other flows the other there is no difference between them it makes complete sense . Also math is easy with ternary take for instance take the base 3 number 20120 177 2 represents-1 and negate it reverse the flow of electricity of each bit so -1 is +1 visa versa and zero stays unchanged then with the correct number formats and hardware you get 10210 or 020120 which is -177 .

Answer : Of course we d be able to hold more data per bit just like our decimal number system can hold far more data in a single digit . But that also increases complexity . Binary behaves very nicely in many cases making it remarkably simple to manipulate . The logic for a binary adder is far simpler than one for ternary numbers or for that matter decimal ones .

Would some compexity of the hardware power consumption or chip density offset any gains in storage and computing power .. . Answer : Lots of misinformation here . Binary has a simple on off switch . Trinary Ternary can use one of 2 modes : Balanced aka -1 0 +1 or unbalanced 0 1 2 but is not simply on or off or more correctly has 2 on states . With the expansion of fiber optics and expansive hardware ternary would actually take us to a much more expansive and faster state for a much lower cost . Modern coding could still be used much like 32-bit software is still able to be used on 64 bit hardware in combination with newer ternary codes at least initially . Just need the early hardware to check which piece of info coming through or the software to announce ahead of time if it is a bit or a trit . Code could be sent through 3 pieces at a time instead of the modern 2 for the same or less power . With fiber optic hardware instead of the modern on off binary process it would be determined by 0 off and the other 2 switches as orthogonal polarizations of light . As for security this could actually be made massively more secure for the individual as each PC or even user is set to a specific polarization specs that is only to be sent received between the user and the destination . The same would go for the gates with other hardware . They would not need to be bigger just have the option for 3 possibilities instead of 2 . There has even been some theories and even possibly starting some tests on the Josephson Effect which would allow for ternary memory cells using circulating superconducting currents either clockwise counterclockwise or off . When compared directly Ternary is the integer base with the highest radix economy followed closely by binary and quaternary . Even some modern systems use a type of ternary logic aka SQL which implements ternary logic as a means of handling NULL field content . SQL uses NULL to represent missing-data in a database . If a field contains no defined value SQL assumes this means that an actual value exists but that the value is not currently recorded in the database . Note that a missing value is not the same as either a numeric value of zero or a string value of zero length . Comparing anything to NULL even another NULL results in an UNKNOWN truth state . For example the SQL expression City Paris resolves to FALSE for a record with Chicago in the City field but it resolves to UNKNOWN for a record with a NULL City field . In other words to SQL an undefined field represents potentially any possible value : a missing city might or might not represent Paris . This is where trinary logic is used with modern day binary systems albeit crude . Comment : This is a late response that probably won t do anyone any good but I contend that your comparison of the binary trinary transition being analogous to the 32-bit 64-bit transition is fallacious . In the latter case nothing truly changed about the function of the hardware at a fundamental level the instruction mov eax ebx will do precisely the same thing in either instruction-set . With the trinary binary distinction this is no longer a reasonable guarantee : a trinary register may look very different from a binary register mov eax ebx might not mean the same thing to both encodings . Comment : @bionicOnion : I don t see a problem with backwards compatibility . The binary code 89 d8 in 0 1 bits would stay the same in trits but you get a lot more opcodes where any one of these 16 trits can be -1 . And those are not the same opcode .", "Question : Isn t a three state object immedately capable of holding more information and handling larger values I know that processors currently use massive nets of XOR gates and that would need to be reworked .

Answer : There are also theories that suggest that fiber optics could use light frequencies i.e.color to differentiate states thereby allowing a near infinite depending on resolution of the detection unit number of base possibilities . Logic gates are definitely feesible for any base but let s use trinary for an example : .. . .. . For a trinary XOR gate it could be exclusive to one or any of the three states it is comparing OR one of the other three states . It could also tie two of the three states together for a binary output . The possibilities increase literally exponentially . Of course this would require more complex hardware and software but the complexity should decrease the size and more importantly the power read heat . There is even talk of using trinary in a nano computing system where there is a microscopic bump a hole or unchanged to represent the three states . Right now we are in sort of a QWERTY type problem . Qwerty was designed to be inefficient because of a problem with typing mechanics that no longer exists but everyone who uses keyboards today learned to use the qwerty system and no one wants to change it . Trinary and higher bases will someday break through this issue when we reach the physical limitations of binary computing . Maybe not for another twenty years but we all know that we cannot continue doubling our capability every year and a half forever .", "Question : Isn t a three state object immedately capable of holding more information and handling larger values I know that processors currently use massive nets of XOR gates and that would need to be reworked .

Answer : A lot of it has to do with the fact that ultimately bits are represented as electrical impulses and it s easier to build hardware that simply differentiates between charged and no charge and to easily detect transitions between states . A system utilizing three states has to be a bit more exact in differentiating between charged partly charged and no charge . Besides that the charged state is not constant in electronics : the energy starts to bleed eventually so a charged state varies in actual level of energy . In a 3-state system this would have to be taken into account too . Comment : Actually I think most ternary logic uses +1 0 and -1 states not 0 +0.5 and +1.0 states .

Answer : Another major hurdle is that there are a much larger number of logic operations that would need to be defined . The number of operators is found by the formula b b i where b is the base and i is the number of inputs . For a two input binary system this works out to 16 possible operators . Not all of this are usually implemented in gates and some gates cover more than one condition however all of them can be implemented with three or less of the standard gates . For a two input ternary system this number is much higher about 19683 . While several of these gates would be similar to one another ultimately the ability to design basic circuits manually would be almost impossible .

Answer : Screwball s reply is correct and corrects some of the misstatements offered here . Those who replied about fractional positive values completely missed the concept of the ternary system which is based on 0 +1 and -1 . When first constructed by the Russians in the 1950 s the competition between USSR and USA was intense . I suspect that politics between the two had a lot to do with the USA s binary s eventual popularity over the USSR s ternary . From what I ve read there are some ternary computers in use . Moscow has some in use at their university and IBM has some in its labs .

I ll add that to my post . Thanks Comment : Sorry I forgot . Consider it done : Comment : Actually thank you .. . Answer : Those are some very good questions . Let s tackle each point one by one : .. . .. . My question is what actually are these keypoints Keypoints are the same thing as interest points . They are spatial locations or points in the image that define what is interesting or what stand out in the image . The reason why keypoints are special is because no matter how the image changes.. . whether the image rotates shrinks or is subject to distortion you should be able to find the same keypoints in the image . Here s an example from a post I wrote a while ago : .. . .. . http : i.stack.imgur.com L4RUT.png .. . .. . Source : module object has no attribute drawMatches opencv python http : stackoverflow.com questions 20259025 module-object-has-no-attribute-drawmatches-opencv-python 26227854 26227854 .. . .. . The image on the right is a rotated version of the left image . I ve also only displayed the top 10 matches between the two images . If you take a look at the top 10 matches these are points that we probably would want to focus on that would allow us to remember what the image was about . We would want to focus on the face of the cameraman as well as the camera the tripod and some of the buildings in the background . You see that these same points were found between the two images and these were successfully matched . Therefore what you should take away from this is that these are points in the image that are interesting and that they should be found no matter how the image is distorted . I understand that they are some kind of points of interest of an image . I also know that they are scale invariant and I know they are circular . You are correct . Scale invariant means that no matter how you scale the image you should still be able to find those points . .. . .. . Now as what William said in his comment to you above keypoints are really just spatial locations in the image . What makes keypoints different between frameworks is the way you describe these keypoints . These are what are known as descriptors . Each keypoint that you detect has an associated descriptor that accompanies it . Some frameworks only do a keypoint detection while other frameworks are simply a description framework and they don t detect the points . There are also some that do both - they detect and describe the keypoints . SIFT and SURF are examples of frameworks that both detect and describe the keypoints . .. . .. . Now what we re venturing into is the descriptor part - scale and orientation . The keypoints we ve nailed that concept down but we need the descriptor part if it is our purpose to try and match between keypoints in different images . Now what you mean by circular .. . that correlates with the scale that the point was detected at . Take for example this image that is taken from the VLFeat Toolbox tutorial http : www.vlfeat.org overview sift.html : .. . .. . http : www.vlfeat.org demo sift basic 2.jpg .. . .. . You see that any points that are yellow are interest points but some of these points have a different circle radius . These deal with scale . How interest points work in a general sense is that we decompose the image into multiple scales . We check for interest points at each scale and we combine all of the points together that build the output . The larger the circle the larger the scale was that the point was detected at . Also there is a line that radiates from the centre of the circle to the edge . This is the orientation of the keypoint which we will cover next . Also I found out that they have orientation but I couldn t understand what actually it is . It is an angle but between the radius and something Basically if you want to detect keypoints regardless of scale and orientation when they talk about orientation of keypoints what they really mean is that they search a pixel neighbourhood that surrounds the keypoint and figure out how this pixel neighbourhood is oriented or what direction this patch is oriented in . This is important for matching so that you can match keypoints together . Take a look at the first figure I have with the two cameramen - one rotated while the other isn t . If you take a look at some of those points how do we figure out how one point matches with another We can easily identify that the top of the cameraman as an interest point matches with the rotated version because we take a look at points that surround the keypoint and see what orientation all of these points are in.. . and from there that s how the orientation is computed . Usually when we want to detect keypoints we just take a look at the locations . However if you want to match keypoints between images then you definitely need the scale and the orientation to facilitate this . .. . .. . Hope this helps", "Question : null .. .

The first one is the fact that the main yellow orientation has a 36bin histogram and the descriptor green orientations are 8bin this allows for an error of a couple 30 of degrees . The second one is that the descriptor histograms green are calculated after the feature area was rotated by its main yellow orientation so they would at very least be shifted by this rotation . But the most important reason is that both orientations are calculated from the same region but a different neighbourhood different in size and position altoghether so the gradients of them need not to be similar at all .", "Question : I am using VLfeat open-source for extracting SIFT keypoints and their descriptions .

Does that make sense Comment : your example is far too constructed and easy . in reality you can t make any assumptions about the amount of translation rotation shearing that s why you have to rely on comparing features not keypoint locations . Comment : Well its an incredibly simplified example so to get the point across . But anyway surely you can be able to have an image with known keypoints that you re happy with then be able to know the relationship between all of these i.e . the relational distances between them and the shape of the keypoints and use that to compare with another images keypoints to get ride of those that don t fall roughly into that known shape from your own image on top of comparing features too obviously .. . Answer : Keypoint matching is a problem with several dimensions . These dimensions are : .. . .. . spatial distance ie the x y distance as measured from the locations of two keypoints in different images .. . feature distance that is a distance that describes how much two keypoints look alike . Depending on your context you do not want to compute the same distance or you want to combine both . Here are some use cases : .. . .. . optical flow as implemented by opencv s sparse Lucas-Kanade optical flow http : docs.opencv.org modules video doc motion analysis and object tracking.html calcopticalflowpyrlk . In this case keypoints called good features are computed in each frame then matched on a spatial distance basis . This works because the image is supposed to change relatively slowly the input frames have a video framerate .. . image stitching as you can implement from opencv s features2d http : docs.opencv.org modules features2d doc features2d.html free or non-free http : docs.opencv.org modules nonfree doc feature detection.html . In this case the images change radically since you move your camera around . Then your goal becomes to find stable points ie points that are present in two or more images whatever their location is . In this case you will use feature distance . This also holds when you have a template image of an object that you want to find in query images . In order to compute feature distance you need to compute a coded version of their appearance . This operation is performed by the DescriptorExtractor http : docs.opencv.org modules features2d doc common interfaces of descriptor extractors.html class . Then you can compute distances between the output of the descriptions : if the distance between two descriptions is small then the original keypoints are very likely to correspond to the same scene point . Pay attention when you compute distances to use the correct distance function : ORB FREAK BRISK rely on Hamming distance while SIFt and SURF use a more usual L2 distance . Match filtering .. . .. . When you have individual matches you may want to perform match filtering in order to reject good individual matches that may arise from scene ambiguities . Think for example of a keypoint that originates from the corner of a window of a house . Then it is very likely to match with another window in another house but this may not be the good house or the good window . You have several ways of doing it : .. . .. . RANSAC performs a consistency check of the computed matches with the current solution estimate . Basically it picks up some matches at random computes a solution to the problem usually a geometric transform between 2 images and then counts how many of the matchings agree with this estimate . The estimate with the higher count of inliers wins .. . David Lowe performed another kind of filtering in the original SIFT paper . He kept the two best candidates for a match with a given query keypoint ie points that had the lowest distance or highest similarity . Then he computed the ratio similarity query best similarity query 2nd best . If this ratio is too low then the second best is also a good candidate for a match and the matching result is dubbed ambiguous and rejected . Exactly how you should do it in your case is thus very likely to depend on your exact application . Your specific case .. . .. . In your case you want to develop an alternate feature descriptor that is based on neighbouring keypoints . The sky is obviously the limit here but here are some steps that I would follow : .. . .. . 1 . make your descriptor rotation and scale invariant by computing the PCA http : en.wikipedia.org wiki Principal component analysis of the keypoints : .. . .. . Form a matrix from KP locations in current image .. . cv : : Mat allKeyPointsMatrix gatherAllKeypoints keypoints .. . .. . Compute PCA basis .. . cv : : PCA currentPCA allKeyPointsMatrix 2 .. . .. . Reproject keypoints in new basis .. . cv : : Mat normalizedKeyPoints currentPCA.project allKeyPointsMatrix .. . .. . .. . 2 . optional sort the keypoints in a quadtree or kd-tree for faster spatial indexing .. . .. . 3 . Compute for each keypoint a descriptor that is for example the offsets in normalized coordinates of the 4 or 5 closest keypoints .. . 4 . Do the same in your query image .. . 5 . Match keypoints from both mages based on these new descriptors . Comment : I ve edited my question to further explain myself Comment : I ve added a section that addresses your problem more specifically . Comment : I ve been looking into that for the past couple of days and it is so confusing.. . Could you elaborate a bit more please @sansuiso", "Question : In reference manual of OpenCV 2.4.3 KeyPoint : : class id is described as object id that can be used to clustered keypoints by an object they belong to . Due to lack of my adequate knowledge about keypoint I can t understand whats the purpose of class id . My another question is by using feature detector descriptor and matcher we can detect matching keypoints of a query object in a training image . But how can segment out the query object in the training image . Can we use grabcut or watershed algorithm if yes how Answer of either question will be helpful . Thanks in advance.. . .. . Answer : The class id member field can be used in practice to store any information that you find useful for each keypoint . As the documentation says you can store for example the id of a detected object . For example you have an image extract keypoints from it e.g . with SURF run some object detector with these features and the result is that each input feature contains now in class id the id of the corresponding object or -1 if they are attached to no object . I don t actually know if this field is filled by some OpenCV function or it is just for your use . Regarding your second question matching features may not be enough to segment out your object because features can be located inside the object so that you don t get any information about the outline . This is a good starting point though if you have more information about the object . For example if you know that your object is planar a poster on the wall you can use the feature matches to compute a homography between the input and the training images . This would give you an outline . Or for example a large collection of close matched features may be an indication of the presence of an object . From that you may try some other color segmentation edge matching etc . Comment : @ChoronoTrigger thanks for your helpful ans . but class id is not still clear to me . what did you mean by run some object detector with these features Comment : I mean that any algorithm can use that field for information purposes .

SIFT http : en.wikipedia.org wiki Scale-invariant feature transform aims to find highly-distinctive locations or keypoints in an image . The locations are not merely 2D locations on the image but locations in the image s scale space meaning they have three coordinates : x y and scale . The process for finding SIFT keypoints is : .. . .. . 1 . blur and resample the image with different blur widths and sampling rates to create a scale space .. . 2 . use the difference of gaussians http : en.wikipedia.org wiki Difference of Gaussians method to detect blobs at different scales the blob centers become our keypoints at a given x y and scale .. . 3 . assign every keypoint an orientation by calculating a histogram of gradient orientations for every pixel in its neighbourhood and picking the orientation bin with the highest number of counts .. . 4 . assign every keypoint a 128-dimensional feature vector based on the gradient orientations of pixels in 16 local neighbourhoods .. . .. . Step 2 gives us scale invariance step 3 gives us rotation invariance and step 4 gives us a fingerprint of sorts that can be used to identify the keypoint . Together they can be used to match occurrences of the same feature at any orientation and scale in multiple images . .. . .. . SURF http : en.wikipedia.org wiki SURF aims to accomplish the same goals as SIFT but uses some clever tricks in order to increase speed . For blob detection it uses the determinant of Hessian http : en.wikipedia.org wiki Blob detection The determinant of the Hessian method . The dominant orientation is found by examining the horizontal and vertical responses to harr wavelets http : en.wikipedia.org wiki Haar wavelet . The feature descriptor is similar to SIFT looking at orientations of pixels in 16 local neighbourhoods but results in a 64-dimensional vector . SURF features can be calculated up to 3 times faster than SIFT features yet are just as robust in most situations . .. . .. . For reference : .. . .. .

I just want to know how to use it asstandalon . Any clear instructions Thank you .. . Answer : To begin with it is worth noting that the version of ZendPdf that you are referring to is the version that was originally included in ZF2 but was dropped from the framework some time in 2011 . As a side note I spoke to Matthew Weier O Phinney ZF2 project lead about this at ZendCon 2012 and he said that if anybody wants to put their hand up to maintain this class we can get it back into the ZF2 framework . The ZF2 version that we re talking about here although semantically identical to the ZF1 version is syntactically different due to the fact that the ZF2 developers did the conversion to namespaces and some other refactoring before they decided to split it off from the main project . Most maybe even all of the ZendPdf examples are for Zend Pdf from ZF1 and they won t work with this version unless you deal with the autoloading and the other syntactical differences . I hadn t used this standalone version until today and discovered that it DOES NOT RENDER the resulting PDF document unless you include one folder of source code from the ZF2 framework . In order to make the sample code below run you will need to grab a copy of the ZF2 framework and copy the Zend Memory folder into the library folder that was created when you downloaded ZendPdf from Github . Once you ve done that the following stand-alone PHP code will allow you to use ZendPdf to create a PDF file : .. . .. . This is not production-ready code by any stretch of the imagination . You ll want a more robust autoloader for starters . Anyway I hope this solves your immediate problem and or gets you on the right track .

Answer : I d like to overlay output from PrinceXML onto pages from a PDF in the file system . I m going to build the solution in our Zend framework environment and I think I d prefer if the solution used Zend Pdf if that s possible . Any suggestions I suppose I could use something like fpdf fpdi and somehow channel the PrinceXML output through that but has anyone used Zend Pdf to do an overlay with the output from PrinceXML and a static PDF template file Comment : So you ll produce a PDF document using PrinceXML and then you want to merge some of those pages into an existing PDF document If its just inserting pages from one PDF into another yes you could do that with Zend Pdf or even the command-line pdftk yeah it sux to have to run a binary to get something done but pdftk is awfully quick so the speed may justify the inelegance . But if you want to overlay page that is pick some elements off a page in one document and add to a page in an existing document hmmm no don t know how you would go about doing that in PHP at all . Comment : @JamesG - Thanks for responding James . What I specifically want to do is place the contents of a static PDF from the file system behind a generated PDF from PrinceXML .

I am having issues and believe I do not know how to properly load Zend Framework or external libraries in general . Here is what I have currently : .. . .. . I was using count as a test but I m looking to use the setTextField functions . I do not have a Loader Autoloader.php as referenced in some guides . How do I properly load the library so that I can use the setTextField function PHP 5.4.16 Zend Framework 2.4.4 CentOS7 .. . Answer : There are a few issues with your question . Firstly the Zend Pdf you mentioned above belongs-to ZF1 not ZF2 . If you really are talking about ZF2 then the class is called ZendPdf and can be used as a standalone component - you do not need to have a full copy of ZF2 available for the autloading composer will generate an autoloader - you will just need to require that in your script . Last time I checked which admittedly was a couple of years ago the two versions were functionally equivalent so you should probably just use the version that matches the version of Zend Framework that you re actually using . Which brings me to the next issue . Because I wasn t completely sure which version you were referring to I did a quick text search and discovered that the setTextField method only exists in Zend Pdf from ZF1 not the ZendPdf class that is related to ZF2 so I m not sure why you mentioned ZF2 in your question . But anyway I figured out how to get the ZF2 version working before I made that discovery so I ve included both methods below for completeness . Also you have an error in your require-once statement - it should not have the . : included at the start . Now on to my actual answer . Loading Zend Pdf from Zend Framework 1 Standalone .. . .. . This should work : .. . .. . You will obviously need to adjust the paths in the code above in order to make it work properly but once you do that and run the script you should end up with example.pdf being created . Loading ZendPdf from Zend Framework 2 Standalone .. . .. . Download the ZendPdf project from github https : github.com zendframework ZendPdf using the instructions on the project page or clone the repository directly using git if you prefer . Change into the directory where ZendPdf has been placed and run composer install to download the supporting files . In that same directory ie . the project root of ZendPdf create a file called test.php with the following contents : .. . .. . Run php test.php and the example.pdf file should be created . The magic in that second solution comes from composer which creates the autoload.php file for you . There are many many benefits to using this approach one of which is that you don t have to have a full copy of Zend Framework 2 installed simply to get a working autoloader . Comment : What an amazing answer thank you so much . I was referring to ZF2 but did not realize Zend Pdf was only in ZF1 . After testing it out it looks like ZendPdf doesn t have the ability to edit text fields only draw . I suppose I ll be playing with coordinates for a while . Thank you for the help Comment : You are welcome - glad I could help . Good luck with your coding Comment : I do have one more question if you could still help me . filename new.pdf pdf- save filename works while filename forms new.pdf pdf- save filename doesn t . how do I save open in other directories Comment : What happens when you try to save to the forms directory Do you get a message saying Can not open forms new.pdf for writing If so it is most likely a problem with file-permissions . You need to ensure that the directory you are trying to save the file to A exists and B is writable by the user or group that the script is running as . Comment : Looks like that was it along with changing it to forms new.pdf . Thanks" ] }

Does anyone know what encryption algorithm is used screenshot http : i.stack.imgur.com W7KPy.jpg", "Question : Can someone describe from a network point of view what RPC SUN and or DCE is and why it deviates from standard TCP behavior The way that I understand it is a client reaches out to a server with a unique source port and then switches the source port after the TCP three way handshake finishes . I work with ASA firewalls so this behavior becomes very apparent when the inspection of DCE RPC is not enabled since the firewall will block it because it sees it as a threat . I have read a few MS TechNet articles and other website definitions to include watching about five Youtube videos which all seem to explain it from a programmers perspective but I have yet to fully understand this concept since I am not a programmer . .. . Answer : Note that there is nothing that deviates from standard TCP regarding the RPC protocols . SunRPC or DCE RPC works on top of UDP at least SunRPC can use UDP or on top of TCP . Typically in order for an RPC client to contact call an RPCserver it first contacts some sort of lookup server called portmapper or rpcbind in the case of SunRPC which replies with the location IP address and port-number of where the actual server is running . So from a networking perspective : .. . .. . RPC Servers listens on a random port-number which may change each time that server program is re started . At startup the RPC server connects to the portmapper which runs on a well known port and register itself with which IP address and port-number it s listening on . Normally the portmapper service runs on the same machine as the RPC server programs . When a client wants to connect to or call an RPC service it performs these actions : .. . .. . Connects to the portmapper on a well known standard destination port and asks it where the particular service it wants to connect to is . portmapper replies with the IP address and port-number of the service the client asked for . client tears down the connection to the portmapper .. . client establishes a new connection to the service using the IP address and port-number that pormapper gave it . client calls the RPC service over this new connection which the client may use for multiple RPC calls . These RPC calls are just application message exchanged on top of a TCP connection . In the case UDP is used instead of TCP it works much the same but there s no naturally no connection setup teardown being performed over the network .. . .. . This presents a problem for firewalls since the servers listens on randomly chosen port numbers one cannot administratively allow access to a particular port-number . Instead a firewall wanting to support this kind of setup would need to open up the portmapper port catch the RPC messages going to that well known port of portmapper inspect the message content exchanged with the portmapper to extract the IP address and port-number from the RPC messages the portmapper is itself implemented as an RPC server in order to dynamically open a port between the RPC server and client .

As we went through them we stucked by the dead-code elemination JMHSample 08 DeadCode.java . Excerpt : .. . .. . The measurement of measureWrong will be approximately the same as for the baseline test . Because the return-value of the Math.log is never used . Therefore the HotSpot compiler will eliminate the dead-code . Ok understood but how can the compiler decide that Math.log can be eliminated . As we looked closely to the test we note that Math.log is a native method . And native calls go down to the OS and execute a corresponding lib . Right This lead us to the assumption that native calls could be eliminated by the compiler if their return-value is not used and they don t perform io operations . We wonder what if the lib which resides somewhere in the OS and which handles the native calls from the java world provides no return-value but does io operations e.g . logging . Will those instructions completely be wiped out To proof our assumption we reconstructed the scenario with a simple JMH test and a native call . We compiled three c-native libs to perform : .. . .. . 1 . returning 42 .. . 2 . parameter addition .. . 3 . empty file creation .. . .. . As we called them in a JMH test similarly to measureWrong test none of them has been eliminated not even the one which doesn t perform an io operation . Due to the test result our assumption cannot be confirmed . Native calls cannot be optimized out meaning that Math.log and custom native calls do not have the same basis . They are not equaly native . Maybe we made a mistake in our native lib code and at least the native call of test 1 should have been eleminated . If this is true we will share our code with you . So we searched further and found a term Intrinsics where java code will be replaced with a corresponding to the architecture very optimized code . java.lang.Math.log is having such intrinsic implementation . Are there any relations between the Natives and Intrinsics If the above assumption of the relationship between Natives and Intrinsics is valid will the compiler perform the following steps to eliminate the native call At the compile-time the HotSpot checks the existence of the intrinsic implementation in jdk for the Math.log and replaces Math.log with that code . Afterwards the second check happens where HotSpot looks after the return-value of a method . And on this outcome the HotSpot decides to eliminate the Math.log call completely . Comment : Math.log is acctually an intrinsic . This means it is known to the JIT and substituted with a predefined set of machine instructions . Also native instructions are not eliminated by the jit as it cannot prove they do not have side effects . Android might still treat its native methods as intrinsics . .. . Answer : As we looked closely to the test we note that Math.log is a native method . And native calls go down to the OS and execute a corresponding lib . Right Native calls don t go to the OS they go to a native library via JNI . That may end up going to the OS or it may go into some user provided lib . In the case of native methods in the JDK we can also expect some native calls to be compiled as intrinsics . This lead us to the assumption that native calls could be eliminated by the compiler if their return-value is not used and they don t perform io operations . The JVM does not look into arbitrary native calls to determine what sort of side effects they may or may not have . This means native calls are indeed made as method calls on the assembly level you jump into foriegn code somewhere another frame on the stack etc . . This also means that the JVM cannot eliminate them or their dependant inputs . Native calls cannot be optimized out meaning that Math.log and custom native calls do not have the same basis . Yes . Are there any relations between the Natives and Intrinsics Some native JDK methods are intrinsics . But normal JDK methods can be intrinsics too . The set of intrinsic methods is also different from one JVM to the next . If the above assumption of the relationship between Natives and Intrinsics is valid will the compiler perform the following steps to eliminate the native call The Math.log function is transformed into a special node in the C2 compiler IR intermediate representation . This node can be optimized away because it is known to have no side effects and it s value is never used . If the value is used the JVM knows to emit specialized machine code for this node . In summary : Intrinsics are optimized method replacements built into the JVM compiler . They can be used to replace any method native or otherwise with : .. . .. . 1 . Specialized assembly code .. . 2 . Specialized IR code .. . 3 . An internal JVM method call .. . 4 . A combination of the above Comment : Thank you for the detailed and helpful answer .

Answer : As Benjamin said in his answer TC39 explicitly decided not to include this feature at least for ES2015 . However the consensus seems to be that they will add it in ES2016 . The syntax hasn t been decided yet but there s a preliminary proposal https : esdiscuss.org topic es7-property-initializers for ES2016 that will allow you to declare static properties on a class . Thanks to the magic of babel you can use this today . Enable the class-properties transform according to these instructions http : babeljs.io docs plugins transform-class-properties and you re good to go . Here s an example of the syntax : .. . .. . This proposal is in a very early state so be prepared to tweak your syntax as time goes on . Comment : Yes that s not ES6 . Unless you know what it is you should not use it .", "Question : Is it possible to create private properties in ES6 classes Here s an example . How can I prevent access to instance.property .. . Answer : To expand on @loganfsmyth s answer : .. . .. . The only truly private data in JavaScript is still scoped variables . You can t have private properties in the sense of properties accessed internally the same way as public properties but you can use scoped variables to store private data . Scoped variables .. . .. . The approach here is to use the scope of the constructor function which is private to store private data . For methods to have access to this private data they must be created within the constructor as well meaning you re recreating them with every instance . This is a performance and memory penalty but some believe the penalty is acceptable . The penalty can be avoided for methods that do not need access to private data by adding them to the prototype as usual . Example : .. . .. . Scoped WeakMap .. . .. . A WeakMap can be used to avoid the previous approach s performance and memory penalty . WeakMaps associate data with Objects here instances in such a way that it can only be accessed using that WeakMap . So we use the scoped variables method to create a private WeakMap then use that WeakMap to retrieve private data associated with this . This is faster than the scoped variables method because all your instances can share a single WeakMap so you don t need to recreate methods just so that they re all accessing their own WeakMap . Example : .. . .. . This example uses an Object to use one WeakMap for multiple private properties you could also use multiple WeakMaps and use them like age.set this 20 or write a small wrapper and use it another way like privateProps.set this age 0 . This method could also be done with Map but WeakMap is better because Map will create memory-leaks unless you re very careful and for this purpose the two aren t otherwise different . Half-answers .. . .. . JavaScript is unfortunately a language where half-answers are often more accessible than real ones . The WeakMap approach is technically a half-answer because somebody could have tampered with the global WeakMap object but I consider it less so than other half-answers because all JavaScript code can be broken by mangled globals . It s just something we need to assume trusted code won t do . Scoped Symbols .. . .. . A Symbol is a type of primitive value that can serve as a property name . You can use the scoped variable method to create a private Symbol then store private data at this mySymbol . This is a half-answer because an Object s Symbol keys can be listed by external code . Despite that here s how you would use Symbols : .. . .. . Underscores .. . .. . The old default just use a public property with an underscore prefix . While not a private property by any stretch of the imagination this is easily the simplest most readable and fastest approach . Thanks to the convention s prevalence it does a good job of communicating that the property should be private and that often gets the job done . Example : .. . .. . Conclusion .. . .. . The short of it is that private properties aren t something ES2015 fixed but rather just fiddled around with . So the state of things is that there are a list of options none wholly superior each with pros and cons . I m sorry . Comment : The first example snippet scoped variables is a total antipattern - each returned object will have a different class . Don t do that . If you want privileged methods create them in the constructor . Comment : Wrapping a class inside a function seems to defeat the whole purpose of using classes in the first place . If you already use the function to create an instance you might as well place all your private public members inside that function as well and forget about the whole class keyword . Comment : @Bergi @Kokodoko I edited the scoped variables approach to be slightly faster and not break instanceof . I admit I was thinking of that approach as included only for completeness sake and should have given more thought to how much it is actually capable of .

Answer : Just to add to Benjamin s answer class-variables are possible but you wouldn t use prototype to set them . For a true class variable you d want to do something like the following : .. . .. . From within a class-method that variable can be accessed as this.constructor.foo or MyClass.foo . These class-properties would not usually be accessible from to the class instance . i.e . MyClass.foo gives bar but new MyClass .foo is undefined .. . .. . If you want to also have access to your class variable from an instance you ll have to additionally define a getter : .. . .. . I ve only tested this with Traceur but I believe it will work the same in a standard implementation . JavaScript doesn t really have classes https : developer.mozilla.org en-US docs Web JavaScript Guide Details of the Object Model . Even with ES6 we re looking at an object- or prototype-based language rather than a class-based language . In any function X X.prototype.constructor https : developer.mozilla.org en-US docs Web JavaScript Reference Global Objects Object constructor points back to X . When the new https : developer.mozilla.org en-US docs Web JavaScript Reference Operators new-operator is used on X a new object is created inheriting X.prototype . Any undefined properties in that new object including constructor are looked up from there . We can think of this as generating object and class-properties . Comment : Your points 2 and 3 are incorrect . There is no copying of properties happening and no .constructor property is created by the new call . Comment : @Bergi you are right about 2 : it is not really copying but a lookup up the prototype chain which opens up special possibilities . I will see how I can reformulate this . What do you think is wrong about 3 though function X var x new X x.constructor X is true so for all intends and purposes my statement should be correct Comment : Try var x new X x.hasOwnProperty constructor false . The .constructor property is simply inherited from X.prototype where it is set by default when you create the constructor function the new-operator does have nothing to do with it .

Answer : Since your issue is mostly stylistic not wanting to fill up the constructor with a bunch of declarations it can be solved stylistically as well . The way I view it many class based languages have the constructor be a function named after the class name itself . Stylistically we could use that that to make an ES6 class that stylistically still makes sense but does not group the typical actions taking place in the constructor with all the property declarations we re doing . We simply use the actual JS constructor as the declaration area then make a class named function that we otherwise treat as the other constructor stuff area calling it at the end of the true constructor . Both will be called as the new instance is constructed . Sorta like having 2 constructors where you separate out the declarations and the other constructor actions you want to take and stylistically makes it not too hard to understand that s what is going on too . I find it s a nice style to use when dealing with a lot of declarations and or a lot of actions needing to happen on instantiation and wanting to keep the two ideas distinct from each other . .. . .. . NOTE : I very purposefully do not use the typical idiomatic ideas of initializing like an init or initialize method because those are often used differently . There is a sort of presumed difference between the idea of constructing and initializing . Working with constructors people know that they re called automatically as part of instantiation . Seeing an init method many people are going to assume without a second glance that they need to be doing something along the form of var mc MyClass mc.init because that s how you typically initialize . I m not trying to add an initialization process for the user of the class I m trying to add to the construction process of the class itself . While some people may do a double-take for a moment that s actually the bit of the point : it communicates to them that the intent is part of construction even if that makes them do a bit of a double take and go that s not how ES6 constructors work and take a second looking at the actual constructor to go oh they call it at the bottom I see that s far better than NOT communicating that intent or incorrectly communicating it and probably getting a lot of people using it wrong trying to initialize it from the outside and junk . That s very much intentional to the pattern I suggest . .. . .. . For those that don t want to follow that pattern the exact opposite can work too . Farm the declarations out to another function at the beginning . Maybe name it properties or publicProperties or something . Then put the rest of the stuff in the normal constructor . Comment : Please don t use a prototype method named after the class itself . That s non-idiomatic in JS don t try to make it look like another language . If you really want to use this approach the canonical name for the method is init . Comment : @Bergi - init is a pattern used often and often meant to be called from outside the class when the outside user wants to initialize i.e . var b new Thing b.init . This is a 100 stylistic choice that I d prefer to communicate that it is a 2nd function that is automatically called by taking advantage of the patterns found in other languages . It s far less likely that someone would look at this and assume that they need to call the MyClass method from outside more likely that they d realize the intent is a 2nd method acting in construction i.e . called by itself on instantiation . Comment : Hm I might realise that by looking at the constructor but not from the method name MyClass . Comment : @Bergi - you very well might not realize it at first just from looking at the method name MyClass . But you wouldn t get false assumptions from it either . At worst you might not know JS and think it s the actual constructor...but since it acts like that and the only things happening in the true constructor are declarations...that actually would not be that improper of a way of treating it . Comment : @Bergi - Taking a pattern from another language and applying it to JS in a way that isn t technically what s happening but still works is not completely without precedent . You can t tell me nobody has noticed that the myvar standard way of referring to variables intended to hold jQuery objects isn t conveniently similar to the pattern of having at the beginning of variables that so many PHP programmers are used to . Just that little implication that yeah it s not the same exact thing...but look...it s still a variable because that is a way variables are done in some languages helps .", "Question : Is it possible to create private properties in ES6 classes Here s an example . How can I prevent access to instance.property .. . Answer : Short answer no there is no native support for private properties with JS6 classes . But you could mimic that behaviour by not attaching the new properties to the object but keeping them inside a class constructor and use getters and setters to reach the hidden properties . Note that the getters and setters gets redefine on each new instance of the class . Javascript 6 .. . .. .

Comment : new class is a horrible antipattern http : stackoverflow.com q 10406552 1048572 . Don t do this . If you want to return an object just return an object-literal and don t confuse anyone . Comment : This doesn t really answer the question at all as PrivatePerson is not a class that can be inherited from or whose prototype can be extended it s just a factory function . It should not be called with new either . Comment : What @Bergi and @Quentin Roy are getting as is you are straying away from the actual question in relation to ES6 classes . Just change the return new class .. . to return .. . and change the usage to not use the new keyword .

Answer : The notes in the ES wiki for the proposal in ES6 maximally minimal classes http : wiki.ecmascript.org doku.php id strawman : maximally minimal classes note : .. . .. . There is intentionally no direct declarative way to define either prototype data properties other than methods class-properties or instance property .. . .. . Class properties and prototype data properties need be created outside the declaration . .. . Properties specified in a class definition are assigned the same attributes as-if they appeared in an object-literal . This means that what you re asking for was considered and explicitly decided against . .. . .. . but.. . why Good question . The good people of TC39 want class declarations to declare and define the capabilities of a class . Not its members . An ES6 class declaration defines its contract for its user . Remember a class definition defines prototype methods - defining variables on the prototype is generally not something you do . You can of course use : .. . .. .

ES7 and beyond .. . .. . A new proposal for ES7 is being worked on that allows more concise instance-variables through class declarations and expressions - https : esdiscuss.org topic es7-property-initializers Comment : @wintercounter the important thing to take from it is that allowing defining properties would define them on the prototype like the methods and not on each instance . Maximally minimal classes is still at its very core prototypical inheritance . What you really want to do in your case is share structure and assign members for each instance . This is simply not what classes in ES6 aim for - sharing functionality . So yes for sharing structure you d have to stick to the old syntax . Until ES7 at least : Comment : You might want to mention static properties Comment : Oops brain fart . I forgot that static works only for methods as well .

Comment : It seems like using Symbols is similar to doing const myPrivateMethod Math.random Something.prototype +myPrivateMethod function .. . new Something +myPrivateMethod .This isn t really privacy it s obscurity in the sense of traditional JavaScript . I would consider private JavaScript to mean using closures to encapsulate variables . Those variables are hence not accessible through reflection .

Comment : @Sullivan : my question was what is the value of bpp after you read it from the file . Comment : It has the ascii value of 24 which seems to be an instruction in ascii . .. . Answer : When you read in the data you assume the targa file has 24 bits per pixel file.read char data imageSize 3 without checking the value of bpp . You then pass the image data to OpenGL and say your data is in 32-bpp BGRA format . You should check what the value of bpp is allocate and read the data based on that value and also pass the correct data format to OpenGL BGR or BGRA depending on whether the alpha channel is included in the image or not .

So your buffers are the wrong size and you index them wrongly . That you do so symmetrically for input and output means that it almost works but the padding byte ends up in the image which as it s out by one byte per line results in a diagonal stripe up the image alternating through the colour channels . You reads will be returning less bytes than you expected but you re not checking . Though 6502 http : stackoverflow.com users 320726 6502 is completely correct about you handling 2-byte fields incorrectly - however this particular image is less than 255 pixels wide high so doesn t suffer .

Answer : TGA width and height is written as two bytes I assume that header is of type : .. . .. . then to properly write width which I suppose of type int you have to put at index 12 low byte least significant byte value of width and at index 13 hi byte most significant byte part of width . so if width is 1023 then in binary it is : 1111111111 so at header 12 you need to put 1023 255 which is 11111111 in binary and in header 13 you put 11 : .. . .. . you could actually rewrite above as : .. . .. .

But there might be a control to view tag image files for asp.net Thanks in advance . Comment : Do you want ASP.NET to process the TGA images or do you want ASP.NET to deliver TGA images to a browser to view Comment : yes I want to view TGA images on asp.net . Comment : ASP.NET is a server-side only technology . You can t view an image on it . You can either deliver an image for viewing in a browser or read it process it then deliver it to the browser . There s a difference between those two . Which are you after .. . Answer : As you already know browsers do not support TGA images . One alternative might be plugins such as flash silverlight .. . which I believe do support TGA images . If plugins are not an option you will need to convert the TGA image to a format browsers can handle e.g . jpg . You could use an HttpHandler for this . This article http : www.jigar.net articles viewhtmlcontent3.aspx shows the use of httphandlers to generate thumbnails on the fly . You can use this same approach and use a library such as ImageMagick http : www.imagemagick.org script index.php to do the conversion and return the image in jpg format on the fly .

Answer : The version 2.0 specification http : www.dca.fee.unicamp.br martino disciplinas ea978 tgaffs.pdf of the Targa file-format contains a so called Extension area which has a Software ID field . This field holds the name of the application that created the file . Maybe you could check whether Photoshop produces version 2.0 Targa files and if it does what Software ID does it write to this specific field then in your application check for this ID . As Targa 1.0 file-format does not have such a field I m not sure whether detecting Photoshop is possible at all .

MSDN page for D3DX11CreateShaderResourceViewFromFile http : msdn.microsoft.com en-us library windows desktop ff476283 28v vs.85 29.aspx says there is DirectXTex http : directxtex.codeplex.com library that should be able to load .tga files using LoadFromTGAFile http : directxtex.codeplex.com wikipage title TGA 20I O 20Functions referringTitle DirectXTex routine . You should give it a try . If it doesn t work for you you ll have to write your own texture loader . because it was possible to make your loader for textures in D3D9 it should be possible to do the same thing in D3D11 . .tga format is documented somewhere https : en.wikipedia.org wiki Truevision TGA and many beginner tutorials specifically deal with loading this particular format without 3rd party libraries . Two advices : .. . .. . 1 . Next time when in doubt read documentation . 2 . DON T look at .png format . This format loads very slowly jpeg is faster uncompressed bmp is faster dds is faster and most likely isn t suitable for games that need to load many images often it is okay to use it for start menu ending screen etc . Either use uncompressed format such as .tga or since you re using directx use .dds format . Your images most likely will take extra disk space but will load more quickly .

You LOCK it then dump entire pixel array into memory at once and then unlock it . In DX9 generating mipmaps for the texture could also be your responsibility . Comment : I would have to if i had to use D3D9 but i use D3D11 and there is no Lock and Unlock function .

Is there some good links for one to read up on C Comment : Your use of read mode w fgets and fscanf suggests you think the TGA specifications are for text-files while in fact they are in a binary format . Not every image is stored the same way -- it seems you are assuming TGA PPM . Either start experimenting with text-only image-formats such as PPM or look up how to read binary-data and the TGA Specifications . Comment : I should maby read moar up on things before asking . Comment : That never hurts . Try a one-step-at-a-time approach -- your problem description seems that you were already writing out the converted TGA file while the problem clearly originated with your input . Sprinkle lots of printf s into your load image function to continuously check if you get the numbers you expected . .. . Answer : Personal note : A longer answer after reading Why Stackoverflow sucks http : sergworks.wordpress.com 2012 09 26 why-stackoverflow-sucks . That should be Required Reading for everyone who gets Moderator privileges . The problem is your load image code seems designed to read PPM ASCII-based images : .. . .. . Each PPM image consists of the following : 1 . A magic number for identifying the file-type . A ppm image s magic number is the two characters P6 . 2 . Whitespace blanks TABs CRs LFs . 3 . A width formatted as ASCII characters in decimal . 4 . Whitespace . 5 . A height again in ASCII decimal . 6 . Whitespace . 7 . The maximum color value Maxval again in ASCII decimal . Must be less than 65536 and more than zero . 8 . A single whitespace character usually a newline . 9 . A raster of Height rows .. . .. . .. . -- your first fgets reads then discards the magic number line followed by reading the width and height and then discarding the maxval line . It ought to work for PPM images and you could rename this routine load ppm image were it not for a single important issue : after all that ASCII stuff you switch to fread and so here is Warning 1 . Before opening your file decide whether you are going to read exclusively ASCII text or might need to read binary-data . .. . .. . The problem is that text mode w converts certain characters when reading and writing into others . That s built-in behavior in all common C libraries it attempts to fix the end-of-line characters mess that a previous generation of programmers left us with . Now reading text-files in text mode got a bit simpler but reading binary-data is impossible . You can t be sure you got exactly what was in the file . Let s get on with Warning 2 : not all file formats are the same . .. . .. . The above routine works mostly for PPM images but it will fail on TGA because its header is organized differently . The TGA header is described rather well here http : www.paulbourke.net dataformats tga a random pick of Google results . The specification describes bytes so first thing to do is change your fopen line to .. . .. . and by the way a good practice is to test if it was successful : .. . .. . Then you can use fgetc or fread to read one or more bytes . Here comes Warning 3 : use fread with care . fread reads multiple bytes in the order in which they are stored into the file and so you would think it may read an item such as width and height -- each a 2-byte integer value -- in one read operation . But fread does not know the order of the bytes in your system nor in the file itself and so it could be it reads lo-hi as in the specification I pointed to while in your computer the order of bytes in an integer is hi-lo . To clarify : if the file contains this .. . .. . and you read then store this with fread width 1 2 fp these 2 bytes get stored into computer memory in that same order . The bytes are in Big-Endian order the large byte is at the end . But if your computer happens to be a Little-Endian order system you would not get the value 0x0080 128 but 0x8000 32768 instead The way to circumvent this is to read one byte at a time : .. . .. . will always read the data in the correct order : low first then high . Only the sum gets stored in the order for your system but that s now irrelevant . With the above I think I m out of warnings . Using the TGA specifications as a guide you can now open the file read the header one byte at a time until you have all information that s needed and continue to fread your raw image data into memory . You can safely use fread to read your image bytes three at a time because they will appear in the same order into memory as they were read they are not integers or larger so the memory order is not an issue . A good approach to ensure you are reading the correct information is this : .. . .. . 1 . Read one byte at a time to prevent endianness issues . 2 . Add a comment in your code detailing what it is .. . 3 . Print out the value .. . 4 . Check with the specifications if the value is allowed . To get you started after the fopen line and the required check if it worked : .. . .. . . . and so on . When the entire header has been read and you didn t encounter surprises you are ready to set up things to read the actual image data . No changes needed there your existing code should work just fine . .. . .. . Post-edit : I see I used .. . .. . where the color map type is in fact a byte not an integer . That is to allow a belt-and-suspenders approach . If you encounter the end of the file while you are reading the header the code that fgetc returns is EOF . EOF cannot be stored into a char because it is an integer value : 0xFFFFFFFF more accurately : int -1 . If you store it into a char you cannot distinguish it from the perfectly okay value 0x000000FF the value 255 . The belt-and-suspender approach is to check each and every single byte : .. . .. .

Why is the position of an image on the screen contained in the data for the image itself I would expect that images don t care about where they are positioned since that s the responsibility of the rendering engine . Could it have to do with the fact that TGA images were designed for special video cards Here s a link-to the TGA spec for reference : http : www.dca.fee.unicamp.br martino disciplinas ea978 tgaffs.pdf .. . Answer : After some conversation we ve deduced that these fields were used to decompose large images into many smaller images . For example the 3Dfx video cards were most efficient at drawing full-screen images if you split the image into 256x256 blocks . The offset of those blocks on the screen could be represented using this field which would allow the renderer to reconstruct the original image .

I need to build software to automate some task for AutoCAD 2012 . But I am confused with the following : - .. . .. . 1 . Should I start to develop a plugin for AutoCAD or should I develop a standalone software 2 . ObjectARX SDK is available for AutoCAD 2014 and later versions only . Can I use this ObjectARX SDK to develop tool for AutoCAD 2012 Thanks to all for your valuable suggestions and time . Comment : See also the tag wiki for AutoCAD http : stackoverflow.com tags autocad info .. . Answer : Welcome to AutoCAD development Indeed there is a getting started tutorial at http : www.autodesk.com myfirstautocadplugin and a blog with lots of samples for various scenarios as http : adndevblog.typepad.com autocad and a broader overview of the all the APIs available at http : www.autodesk.com developautocad .. . .. . About your questions : .. . .. . 1 . You can do a plugin or external app but notice that only plugins can use the pure .NET API the external apps can only use COM API which is not as good and quite old . If you need to automate from external apps check the AutoCAD Console available on AutoCAD 2013+ .. . 2 . The SDK is very similar but Autodesk made a major remodeling of the API on 2013 release therefore anything developed for 2012 will not work on 2013 you need to rebuild at least . If you have a code developed for 2013 it can work until 2016 but testing is recommended .", "Question : I have an application which is written in C++ and I have to migrate it to C . This application is an extension for AutoCAD . resbuf in C++ AutoCAD API is a linked-list which handles all AutoCAD basic data types . It looks like this .. . .. . So each resbuf contains specific data described by restype member . For example restype with code 410 is layer name . So on C it looks like this .. . .. . In that application resbuf structure is used as a way for working with AutoCAD objects and wherever I meet resbuf I change it on using object Line Polyline MText and so on directly . But now I found usage of resbuf with code 10 and I opened the documentation and found the following .. . .. . 10 : Primary point . This is the start point of a line or text entity center of a circle and so on . And I don t know the way of migrating it . Because for each object it s a different property . The only idea is something like this . But I don t like it . May be there is a better way of doing it . Do you have any idea .. . Answer : First resbuf was the ADS version of the AutoCAD API which was a C API . ObjectARX which is the C++ version of the AutoCAD API still use resbuf for XData but not anymore for Entity property access . In ObjectARX C++ and the AutoCAD .Net API C VB.Net you access entity property using specific methods and accessors respectively see examples at the bottom . Use the DXF table http : www.autodesk.com techpubs autocad acad2000 dxf group codes in numerical order dxf 01.htm to read code in a resbuf linked-list . Second code DXF 410 is just a string . Someone may use it and store a layer name if he wants but entity layer is referenced by DXF code 8 . Last DXF code 10 means the first meaningful point for the entity . This can either be the center of a circle or the 1st point of a line etc.. . This is why using the resbuf requires a lot more attention and understand how the underlying AutoCAD database structure is organized than using accessors . For Example : .. . .. . ADS C .. . .. . ObjectARX C++ .. . .. . AutoCAD .Net C", "Question : There is a .Net Autocad plugin in which a WCF service is used to call a method on another process external to Autocad . Autocad entities are wrapped in custom classes and passed through WCF . Once the call returns the plug-in needs to write the result back into Autocad database . Here is the problem : ObjectId is needed to fetch the object and write the result back WCF serialize the data and ObjectId is not serializable . So I don t have access to the object . Is there any workaround solution for this .. . Answer : For each of your entity you can get handle directly without mediator objectId . use Entity.Handle property . Further from autocad guide .. . .. . Each object contained with in the Database object is assigned several unique ids . The unique ways you can access objects are : Entity handle ObjectId Instance pointer The most common method is to access an object by its Object Id . Object Ids work well if your projects utilize both COM interop and the managed .NET API . If you create custom AutoLISP functions you may need to work with entity handles . Handles are persistent between AutoCAD sessions so they are the best way of accessing objects if you need to export drawing information to an external file which might later need to be used to update the drawing . The ObjectId of an object in a database exists only while the database is loaded into memory . Once the database is closed the Object Ids assigned to an object no longer exist and maybe different the next time the database is opened .", "Question : null .. . Answer : When we ask User to select distance by acedGetDist User can input value by keyboard like 4.0 or click pair or points . Everything is OK as long as User draws in scale 1 : 1 . but when User want to draw in other scale distance given by points will be the same but if User input value I need to recalculate it . How can I check how User input value First I tried to check system variable lastpoint but it is not updated when pick points in acedGetDist . I use ZWCAD maybe that s why it s not updated .. . .. . Any ideas how to check how User input value Comment : I don t believe ZWCAD will have the same APIs as AutoCAD not you tagged your question as autocad-plugin and objectarx both applies only to AutoCAD not ZWCAD Comment : Yes ZWCAD API is not exactly the same as AutoCAD . As ZWCAD don t have all functionality of AutoCAD but it is very simmilar at least at this point . Both AutoCAD API and ZWCAD API have acedGetDist and it should work the same way . Do You know answer how can I handle this problem on AutoCAD if AutoCAD solution will fail on ZWCAD we can treat it as ZWCAD API bug and then for sure I will remove tags . Comment : so I made a quick test with AutoCAD API : the acedGetDist method always return the true value not the scaled value regardless the input method pick point or numeric value and regardless the scale CANNOSCALE value Comment : And that is how I understand it should be . To know scale I don t use CANNOSCALE maybe I should but I don t In my application-settings I let User to input scale and save it into drawing XData of Dictionary . Application is for traffic organization default scale is 1 : 1000 so drawing in meters . But sometimes needs to draw in other scale like 1 : 500 In application I draw for example pedestrian crossing . So I ask for width by acedGetDist when User click points everythig is OK . but if write 4.0 User want 4 meters of pedestrian crossing even if scale is 1 : 500 Comment : oh ok so if you keep the scale on your xData then AutoCAD or ZWCAD will not know it.. . I would say that you can ask the user for unit to ensure is correct whenever your scale is not default or as expected by your app logic", "Question : In my AutoCAD LISP plugin I run external application by startapp then need to do some action after external application will be closed .

Answer : You should not manually load AcMgd AcCoreMgd nor AcDbMgd on your DLL library there references are loaded on AutoCAD process acad.exe by default only from acad.exe folder and when you NETLOAD your DLL library i.e . your plugin it will link automatically . When compiling your DLL library set Copy Local FALSE on AutoCAD references . If you leave it TRUE AutoCAD will behave unexpectedly . Also you should not use AutoCAD references on external applications i.e . a .EXE project on Visual Studio . The references are in fact a thin layer to access the real implementation in C++ compiled as .ARX dynamic libraries and will only work in process with acad.exe . If you need to call AutoCAD from an external application you can use COM Automation or AutoCAD Console . See this reply http : stackoverflow.com a 38480420 4838205 . That said starting on AutoCAD 2012 you can use Autoloader mechanism http : adndevblog.typepad.com autocad 2013 01 autodesk-autoloader-white-paper.html . In summary you can define a PackageContents.xml file that will define which DLL library to load according to the AutoCAD version that your customer have . That s the easiest way to NETLOAD your plugin into AUtoCAD . If you still need to register your plugin DLL library manually you can create a registry key for it https : knowledge.autodesk.com support autocad troubleshooting caas sfdcarticles sfdcarticles How-to-autoload-DLLs-with-AutoCAD.html but it s a bit tricky due many AutoCAD versions of verticals e.g .

You can try to hide Editor.StartUserInteraction it and use a synchronous way to send a command to AutoCAD like P Invoke of acedCmd but I ve tried it and it crashes AutoCAD .

Answer : You need to change the AttributeDefinition in the block table record property Constant not the AttributeReference . This property is shared with all the AttributeReference . From the docs : .. . .. . AutoCAD itself never creates a constant AttributeReference object . AutoCAD creates the AttributeReference objects for each BlockReference based on the AttributeDefinition objects within the referenced BlockTableRecord .

AutoCAD 2016 supports Microsoft Visual Studio 2012 and 2013 .. . .. . AutoCAD 2015 supports Microsoft Visual Studio 2012 .. . .. . .. . .. . .. . Why is it like that I understand that you need to use particular .NET Framework versions according to your AutoCAD versions . But why the IDE You can set your target framework version for each project . Is it because of compiler debuger issues We are planning to upgrade from AutoCAD 2012 to AutoCAD 2016 . So we need a new IDE for our plugins and would prefer the latest Visual Studio version 2015 .. . Answer : This strict VS version is for ObjectARX C++ only . For .NET you just need the proper framework version to develop or if you already have a DLL legacy compatibility should work . But there is an exception see below : .. . .. . 1 . AutoCAD 2007 - 2012 : compile your code with AcDbMgd and AcMgd and your code should work on all these versions except if you use a feature that is not available on the version you re executing .. . 2 . AutoCAD 2013 - 2017 : this new cycle also need reference to AcCoreMgd therefore you need a separate compiled DLL .. . .. . For C++ there is a additional requirement regarding Decorated Names https : msdn.microsoft.com en-us library 56h2zst2.aspx and VS compiles the code using this . Therefore you can adjust the Toolset but need the specific version installed to compile your code . I might say that if you re using ActiveX COM you have some different concerns : the references are different on 32 and 64 bit and between AutoCAD major versions so it s easier to use late-binding or compile different DLLs for each version platform .", "Question : There is a .Net Autocad plugin in which a WCF service is used to call a method on another process external to Autocad .

Here is the problem : ObjectId is needed to fetch the object and write the result back WCF serialize the data and ObjectId is not serializable . So I don t have access to the object . Is there any workaround solution for this .. . Answer : You have to serialize the value handle of the ObjectId since it is not serializable : .. . .. . Then when you deserialize your Class object you will be able to get the objectId by calling the method GetObjectId Database database long handleValue Comment : Thanks Zimer for the answer . I am aware of this workaround . But am concerned with GetObjectId performance on large numbers . What does this method actually do Does it create new ObjectId or look for it on the database Comment : @ali : Zimmer is right . In fact I can t see how this plugin is serializing entities otherwise . They too contain the ObjectId . Not to mention they are not marked serializable . They do however implement MarshalByRefObject which means they can be sent via remoting but not WCF not to my knowledge anyways . My guess is they are either using some remoting magic or they re using POCO representation of the entity properties . If the latter is the case then they are doing what Zimer is suggestion . Comment : @ali : Btw.. . Handle s are persisted IDs with the document . ObjectId s are transient IDs with the session . So it s actually retrieving the session s registered ObjectId for the object from the drawing s database for the session . The code will also has to account for the fact that the Handle is a hexadecimal value so use this.. . ObjectId oid currentDB.GetObjectId false new Handle Convert.ToInt64 handle 16 0 Comment : @ali : Based on the documentation of Autodesk ObjectARX this method returns the objectId of the object that has the handle value contained in objHandle so we can say that it will look for it on the database .

The command I m working on creates a new layer or select it as the active layer if it already exist then executes 2 -INSERT commands giving a point selected by the user and a dwg-file . Then the previous active layer is reset as the active layer . The insert-command looks something like this : .. . .. . Note : All the line-breaks in the command are added as vbCR not vbCrLf . My question is how can I achieve the same result in .NET against ObjectARX I can t use SendStringToExecute because it is async with no callback so in other words I can t reset the current layer once it s done executing . There has to be some way to replicate this functionality in pure .NET code probably using the BlockTable but I have no idea how .

I also tried to use myDatabase.Insert transform otherDatabase False and the command-prompt said something about blocks already existing and thus beeing skipped yet I still saw no changes . I have no idea how much magic the -INSERT command actually does behind the scenes but would it be viable to replicate it in .NET Or is it somehow availible to be called as a normal method not as a text-command sent to be processed by AutoCAD .. . Answer : The code example in the Through the Interface post imports the blocks but does not insert them into the drawing . You have to create a BlockReference and add it to the model space . It also inserts all the blocks from the file not the file as a single block . Here is the code I use to import a file as a whole block . This function returns a block reference you can insert into your drawing . Here would be the example of using that function to insert a block into the file . In this example I use a jig which allows the user to drop the object onto a location they want otherwise you could just set the position . And here is also the CheckLayer function I called . Just as a note Kean s blog is a great resources I pretty much learned all of the above code from there . For completeness sake here is the Jig class i reference in the insert code .. . .. . One note regarding working in .NET ObjectARX there is a an issue with the single-threaded nature of AutoCAD and the fact that the .NET garbage collector runs on a separate thread . If you create any temporary AutoCAD objects that do not get added to the database you must explicity call .Dispose on them or AutoCAD may crash The crash will seem random too since it will be triggered by the garbage collector thread . See this post http : through-the-interface.typepad.com through the interface 2008 06 cleaning-up-aft.html . Comment : Thanks . I m checking this once I get to work tomorow . Also I use the Using-statement on almost anything so everything get s disposed guaranteed even with exceptions etc . . Comment : Do you know if there is any simple way to get autocad to pop-up with it s enter multiple attributes strings -window Like if I just use the -IMPORT command it will pop-up with a window telling me to enter Revision Number and Revision Name . Can I get the same behaviour some way in .NET Comment : Not sure about that but you can set attributes in code so you could always just show your own Modal dialog to get the info . Comment : Yeah . I m working on that . Problem is that I have to generate a dialog based on the attributes as there can be any number of them -.- . Insert handled that automagically for me .", "Question : In my AutoCAD LISP plugin I run external application by startapp then need to do some action after external application will be closed . How can I do it maybe I can substitute startapp by something else .. .

I opened up my project files and all the references to Autodesk libraries were missing . To remedy this I added references to the following dll files from ObjectARX 2015 shown in the dlls image attached . I am using the following Autodesk namespaces : .. . .. . Adding the missing references makes the errors go away until I try to test my program at which point I get new errors underlining Autodesk references in gray instead of red as shown in the attached image . I have no idea why the added references are not working . It may also be worth knowing I ve migrated from Visual Studio 2012 to Visual Studio 2013 and AutoCAD 2014 to AutoCAD 2015 enter image description here http : i.stack.imgur.com Bcbdq.png .. . .. . enter image description here http : i.stack.imgur.com YNk55.png Comment : I m unsure why they have that gray line under them . Are yout setting your copy local setting to false for those references Or do you have multiple auto cad libraries of different autocad versions in your references BTW I don t see any reason you should have all of those references . You should only need runtime for what you have in your class . .. . Answer : You need to change your target .NET framework . If the Dll s that you are referencing are built for 4.0 you need to target 4.0 . If they are built for 4.5 you need to target 4.5 . Here are the steps to change the target framework if you don t know how . http : msdn.microsoft.com en-us library bb398202.aspx", "Question : what s the use of this folder I need to load a lisp in automatic way without using acad.lsp and acaddoc.lsp .

In response from GCM I get an empty objet field data . I want to send push-notification with message by client in a browser . How can I do that .. . Answer : First for downstream messaging GCM provides two types of payload : notification and data . In Data payload you need to include the developer s custom key-value pairs only and the client app must handle the message . You can read the documentation here https : developers.google.com cloud-messaging concept-options payload about data in the message payload . I will suggest you to read this documentation Implementing GCM Client on Chrome https : developers.google.com cloud-messaging chrome client to know more information in setting up the GCM in the browser client . Make sure that the enable API that you use is Google Cloud Messaging for Android . Because Google Cloud Messaging for Android will give you access to the normal GCM API .

Tnx .. . Answer : The official docs http : developer.android.com google gcm index.html on Google Cloud Messaging for Android does mention that GCM can be used to develop an instant messaging app . ...or it could be a message containing up to 4kb of payload data so apps like instant messaging can consume the message directly .

Answer : The cloud infrastructure will mostly remain the same so existing GCM apps should continue to work fine . Although I haven t found any mention of a deprecation policy from Google yet it would be unusual for Google to and they have little reason to break existing GCM infrastructure SDK code .

Answer : FCM Firebase Cloud Messaging is a improved version of the Google Cloud Messaging API it have all features of GCM with some additional features also . Google recommending this they wrote Firebase is known for being cross-platform so FCM now makes a natural fit in the Firebase suite of features designed for Android iOS and mobile web . Google just announced that Google Cloud Messaging is now Firebase Cloud Messaging . See new Release https : developers.google.com android guides releases may 2016 - v90 .. . .. . Source URL : https : developers.google.com cloud-messaging faq .. . .. . 2 . FCM over GCM . Answer : FCM is the new version of GCM under the Firebase brand . It inherits GCM s core infrastructure with new SDKs to make Cloud Messaging development easier . Benefits of upgrading to FCM SDK include : .. . .. . Simpler client development . You no longer have to write your own registration or subscription retry logic . An out-of-the-box notification solution . You can use Firebase Notifications a serverless notifications solution with a web-console that lets anyone send notifications to target specific audiences based on Firebase Analytics insights . Source URL : https : firebase.google.com support faq gcm-fcm .. . .. . 3 . Is GCM now depreciated . Are they going to stop all services support of gcm . Answer : Yes some features of GCM is already depreciated and now in coming days GCM are going to fully depreciated . See here https : developers.google.com cloud-messaging android legacy-regid registration-state-sync-handling But Google says We will continue to support the current version of GCM Android and iOS SDKs because we know a lot of developers are using GCM SDKs today to handle notifications and client app upgrade takes time . But all new client-side features will be added to FCM SDKs only moving forward . You are strongly encouraged to upgrade to FCM SDKs . Source URL : https : developers.google.com cloud-messaging faq .. . .. . 4 . How to update my old applications from GCM to FCM . Answer : Import your GCM project as a Firebase project - : .. . .. .

Comment : I am glad it helps you . @JordanChaffins Comment : Can i expect FCM to be glitch free as i faced many troubles using GCM. . @RobiKumarTomar Comment : Yes GCM is depreciated now . See here This is incorrect . GCM has not yet been deprecated . The thing you linked to was an older GCM API that was deprecated back in 2015 in favor of using InstanceID to get registration tokens for GCM . Comment : Yes we all can hope this but FCM messaging and notifications development is very easier than GCM . @ManishNikam", "Question : i got confused by gcm today . I dont know if my registrationid is correct . I got characters and a colon in front of a registrationid starting with APA . The Pattern is xXXXxxX : APA.. . . I implemented google-cloud-messaging for a android client using the example from here : https : developers.google.com cloud-messaging android client . If i use a older implementation for example with GCMRegistrar i only get a registration id starting with APA . Till now i though a registration id has to start with APA . Is the stuff before the colon some tokenspecific stuff Do i have to pass the full token to the webservice or is it okay if i cut the chars before the colon and send the registration starting with APA Comment : BTW : GCM is deprecated . Use FCM Comment : GCM is not deprecated . they will support the current version of gcm but new features will be added to fcm as google announced . developers.google.com cloud-messaging faq https : developers.google.com cloud-messaging faq .. . Answer : GCM Registration Token is equal to registration id so is Instance ID . As I mentioned in my answer here http : stackoverflow.com a 37671576 4625829 : .. . .. . An FCM Token or much commonly known as a registrationToken like in i.stack.imgur.com Ubwmo.png google-cloud-messaging questions tagged google-cloud-messaging . As described in the GCM docs : .. . .. . An ID issued by the GCM connection servers to the client app that allows it to receive messages . Note that registration tokens must be kept secret . Different terms point to the same thing . The format for the registration token may also vary as seen this answer http : stackoverflow.com q 32809847 4625829 : .. . .. . The GCM registration token is usually around 140 chars in length and can contain colons underscores and hyphens . Maximum size is supposed to be 4k . Though I m not entirely sure with regards to the character length I think I ve read on a post here somewhere that it may exceed that number . Do search around . Comment : so i pass xyxzyzz : APA... . to the webservice . Thanks for the Answer Comment : AFAIK yeah . I think I ve encountered a registration token like that before. . Do try it . You can never know for sure if you don t test it out . :", "Question : Google just announced that Google Cloud Messaging is now Firebase Cloud Messaging .

Answer : The periodical refresh never happened and the registration refresh is not included in the new GCM library . The only known cause for registration ID change is the old bug of apps getting unregistered automatically if they receive a message while getting upgraded . Until this bug is fixed apps still need to call register after upgrade and so far the registration ID may change in this case . Calling unregister explicitly usually changes the registration ID too . The suggestion workaround is to generate your own random identifier saved as a shared preference for example . On each app upgrade you can upload the identifier and the potentially new registration ID . This may also help tracking and debugging the upgrade and registration changes on server-side .", "Question : I m creating an android app like Tinder and creating a messaging service similar to Tinder s- in that each user gets a push-notification and messages with one another .

You ll need to re-register every device each time you update your app . 2 . You ll also need to re-register a device if the version of Android it s running has been updated .. . .. .

If you see the second point under the heading Enable GCM on Architectural Overview http : developer.android.com google gcm gcm.html arch page it says : .. . .. . Note that Google may periodically refresh the registration ID so you should design your Android application with the understanding that the com.google.android.c2dm.intent.REGISTRATION intent may be called multiple times . Your Android application needs to be able to respond accordingly . So for handling that you should have a Broadcast Listener which could handle com.google.android.c2dm.intent.REGISTRATION intent which Google send to the app when it has to refresh the registration ID . The broadcast receiver will have the onReceive method with an Intent . From the intent you can get the Bundle using which you can extract the new registration ID from Google . You can save that and send it to the 3rd part server to replace your previous registered ID for that user .

But isShown seems to be unreliable according to this answer s comments http : stackoverflow.com a 26034036 3968618 for example and saving the state gets messy if you want to re-show the dialog .

Answer : I think this is related I started testing on 4.1 today and have found some javascript-events seem to fire twice . Mostly click at the moment . Weirdly if i add-in an alert it sometimes fires once . The behaviour is oddly inconsistent . The javascript-events only respond in this way on android 4.1 . iPhone seems fine as do all previous versions of android i have tried so far including 4.0.x . It seems like an error with the browser or the way its handling javascript to me but thats just a guess .

Answer : Try setting a boolean to check for a double fire within the same dialog . Something similar to : .. . .. . This double fire issue also happens with onTimeSet of a TimePickerDialog and this check also works for those . Comment : Yes that should work . I hope they fix this issue soon . Comment : Toggle back the fired variable to false so that the DatePicker continues to work afterwards . By the way the problem also occurs in the TimePicker dialogs .

The bug https : code.google.com p android issues detail id 34860 c21 is calling onDateSet both upon pressing the Done button and when the dialog is dismissed . The latter is additionally problematic because the date will be set when the user cancels i.e . presses back or taps outside of the dialog . The solution posted here does not resolve this problem .", "Question : so a couple of months ago I ve started developing some WiFi-Direct applications .

In my experience the One Vs worked most of the time where as the One X+ would fail more frequently . .. . Answer : Android updated Wi-Fi Direct API with Jelly Bean in API level 16 . As you already know the core API was first added along with ICS in API level 14 . Here you can find the added classes regarding Wi-Fi Direct .. . .. . Some classes here use WifiP2pManager class as parameter . You better take a look at them yourself : .. . .. . http : developer.android.com reference android net wifi p2p nsd package-summary.html .. . .. . IMO your application might be corrupted manipulated or what-so-ever after this update in API 16 . I see that you have created your own method for sending invitation to other peer altough this is not really needed . Peers get invitation automatically in Wi-Fi Direct . Thus you can leave it handle the invitation process itself . Once again I suggest you take a look at here http : developer.android.com guide topics connectivity wifip2p.html unless you did it before . Comment : Nope my application still works like a charm. . But in the new JB API it s getting better some of the errors are not showing up anymore .

Currently I am building it against API level 19 . After build when I run it on my Jelly Bean device It crashes with error mentioned as the title of this question . I got to know that to avoid this error I need to build my native against Android toolchain generated for API level 16 since Jelly beans starts from api level 16 . I have Android NDK Version android-ndk-r10d . So I went to my NDK directory and used the following command to create a standalone toolchain for API level 16 . Above command created a directory named android-toolchain-16 in usr local . I added the the path usr lo0cal android-toolchain-16 bin to my PATH variable . Then I went on and build my native using the script I have . Then I built my app and tried . But it still crashes .

I did bounce SQLServer after putting the service account it is running under in the domain admins group BTW . Many thanks for your kind review of this long-winded problem . Comment : That code does run if you add it to a simple console program The callstack mentions a CreateUser method . I don t see that directly in the code snippet you have . Where is principal.Save called Comment : It sounds like you covered the bases and then some . By default the security context for SQLCLR is the Log On As account of the SQL Server NT service each instance has its own service so be sure you are setting the Login for the correct instance . If you aren t using Impersonation then this is the only account to configure for security and whatever login calls the stored proc is irrelevant . If you enable Impersonation then the Windows Login not SQL login running the proc is the only security context you need to worry about . You might need to enable delegation for the account being used . Comment : Also have you checked the Windows Event Log There is often additional info in there that could help . And is AD set up with a policy that disallows certain account-oriented actions from certain machines or only allows from certain machines A great test would be if you could create a console app of this code put it on this SQL Server machine and run it from xp-cmdshell which is also running in the security context of the Log On As account of the SQL Server NT service . Comment : rene there s an invocation like p.save down below the code I included after another dozen or so attributes are set .

Answer : You would typically use impersonation if you need to execute your application as a different user usually with more specific access than the one is currently logged in . The term Impersonation in a programming context refers to a technique that executes the code under another user context than the user who originally started an application i.e . the user context is temporarily changed once or multiple times during the execution of an application .

Comment : I will put a request in to my domain admin guys and get the access opened . might take a few days but will let you know", "Question : null .. . Answer : I have an application which has certain functionality secured by performing an Active Directory lookup via DirectoryServices . I am in the midst of migrating this code from a web host in our old domain to a new domain . The code worked flawlessly on the old domain . However errors occur when testing it against the new domain . We have a full trust between domains as our goal is to migrate off of the old domain . The new domain employs the use of read only domain controllers within the domain but restricted from the internal network via firewall rules . Only perimeter DMZ servers in the domain can reach the read only domain controllers . Here is the problematic line of code : .. . .. . When testing against the new domain I am receiving this : .. . .. . COMException 0x8007203a : The server is not operational . and this : .. . .. . ActiveDirectoryServerDownException : The server is not operational . Along with the FQDN of the read only domain controller . Since I am specifying the name of the DC then shouldn t my request go to that DC Could this be a DNS routing issue in our LDAP SRV records I have view only access to DNS and I discovered that the read only DC is referenced in the internal site where the web host resides . Also those SRV records do not have a priority set . They are all 0 . The sys admins insist that there must be a programmatic method for pointing to the primary DC . I have attempted to do so by using roughly 6 variations of my call to PrincipalContext . I would prefer to stick with the modern API and not resort to writing LDAP strings . On the sys admin side of things what can be researched or inspected On the programmatic side of things am I directing my request properly Is there an alternative method or surefire way of avoiding the DC Perhaps it is up to DNS but at this point I am uncertain . Troubleshooting : When I run netstat from the command-line on the web host during an LDAP request I see where an ldap connection is requested to our two writeable DC s . Afterwards a request is also sent to the read only DC and the error is thrown . Comment : When you re creating a new instance of PrincipalContext you re not specifying username and password . Does the logged in user has enough access If yes just try simply binding to domian . using PrincipalContext ctx new PrincipalContext ContextType.Domain mydc.local : 389 . I also see that you re using a default port 389 which is not secure.If you re planning on any types of authentication you need to get your sys admin to install SSL certificate . I highly encourage . It will save you a lot of time . And last thing to try is changing the ContextOptions to SimpleBind . Comment : Thanks for the input . I tried all of that to no avail . After spending a week on this problem I moved on . My resolution was to resort to .NET 2.0 ADSI code in-place of PrincipalContext . That code worked without error .", "Question : null .. .

This code produced no errors and never returns false on the same system that was returning those false negatives . I d like to break it so I can make sure that the LogonUser call isn t going to have the same issue . Comment : I am just curious as to why you need an external .dll to do basic PrincipalContext in .NET. . is there something I am missing here. . Comment : @DJKRAZE the external is for when I switch it over to use the LogonUser call . I missed that when cleaning the code to post it . Comment : you can do that without the external using and or writing some small AD code but I will look at your code more in detail to see if I see any additional issues or possible causes. . Comment : also wonder why you are using a Dictionary instead of a List to store this Dictionary objects if I am not mistaken will fail if you have duplicate keys I would recommend an array Comment : @DJKRAZE This is just a test program who s one job is to try to break the PrincipalContext.ValidateCredentials . The only part of the code that is from the production code that was failing is the AreCredentialsValid call . Everything else is just setting up tests for the AreCredentialsValid .", "Question : null .. . Answer : I am trying to connect to an LDAP server in C using PrincipalContext .

Before the update I used WDTV Live player to stream videos from the PC and everything worked flawlessly . Now the player fails to open mkv files from the PC through DLNA streaming . Other formats can still be played . The same mkv plays fine on both the PC and the WDTV if copied to a flashdrive . And the same file used to play on WDTV before Windows upgrade . So the problem is not in broken mkv or network communication - something must be wrong with the codecs installed on the PC . I m using K-Lite codec pack but the version I had before the upgrade was probably much older than the one I have now . Maybe some settings should be tweaked to make mkv-s play but I have no idea what to check . Any ideas on configuring the media server are appreciated . Update : a detail which may help to solve the problem . When displaying the list of files on WDTV the player shows only filename for mkv videos - no file size time etc . So the problem must be in the container not in codecs . I also tried to encode the same file to mkv and mp4 using the same codec settings . mp4 is played fine while mkv still fails . Comment : do you use Windows shares for streaming Comment : I m using media streaming provided by Windows Media Player and its services . It uses DLNA protocol and used to work perfectly . Comment : I m using Windows shares and the built-in codecs of the WD . DLNA includes no mkv support http : www.dlna.org dlna-for-industry technical-overview Comment : AFAIK DLNA is just a protocol which can be used to stream anything . In my case streaming mkv worked before I reinstalled Windows so it is supported by both server and client . Using shares has its disadvantages e.g . you can not control client device from the server or transcode media on the fly to the format understood by the client .

This thread http : superuser.com questions 472420 handbrake-settings-to-convert-mkv-to-mp4-while-retaining-the-original-quality mentions that there is no need for video-conversion just changing the container might suffice . After reading multiple threads on how to change the container of MKV to MP4 I downloaded and compiled the FFMPEG with libfdk aac support from here http : taer-naguur.blogspot.ca 2013 10 ffmpeg-autobuild-tool-x64.html .

I have 0 knowledge about video-conversion . Comment : Your second command ffmpeg -i input.wav .. . has no video track input . So it can t screw up the video quality . .. . Answer : If you can t play the video after your first command then evidently your TV can t deal with the originally encoded video stream . So - give a shot at re-encoding with another codec . This will produce a high quality re-encoded version it will take a while to re-encode :", "Question : I found this screenshot that s showing that you can add a cover image to an mkv file in a way that it is displayed in the Windows explorer using Shark007+icaros . enter image description here http : i.stack.imgur.com Hl7aC.png .. .

Anyway how could I programmatically add a cover image to an mkv file And would I need to change something in the registry to make Windows display them I m not really looking for code I m more looking for something like the format the cover needs to have and the byte at which I have to inject insert the image file etc . Comment : Why the close vote .. . Answer : You can use the FFmpeg https : ffmpeg.org download.html multimedia framework to attach an image as MKV metadata . More Windows builds can be found at Zeranoe http : ffmpeg.zeranoe.com builds . Example CLI usage : .. . .. . -c copy copy all streams in the source file without re-encoding .. . -attach image.jpg attach a JPEG image .. . -metadata : s : t mimetype image jpeg set the attachement MIME type .. . .. .

Comment : But does attaching an image mean that it is visible in the file explorer of Windows Like on the screenshot . Comment : I just tried it . It always displays the default icon on Windows 8.1 . : Comment : Yeah I already mentioned that tool in my question . And it is not an option for me . I d really like to know what that tool does internally and how I could replicate it . I mean it s probably just some registry changes right Comment : I actually don t want to use any third party tool for that . I also don t want to force my users to have codec packs installed etc . Comment : Of course it is possible . The question is just how And I wouldn t say that ffmpeg is the way . It surely is a way but not really a programmatic solution . It s a workaround I could live with .

Since my MKV file has only Theora video I am okay even if library supports only one type of video stream . .. . Answer : You can only play videos in Flash that the player natively supports . If you write or convert an actual video codec in ActionScript or even use the C to Flash bytecode compiler the performance will not be good enough to get acceptable video quality . For internal purposes we implemented a Motion JPEG display within ActionScript and even though all that did was modify the headers a bit and display a series of jpeg files using mostly native-code the effective framerate was poor .

Comment : Good answer but Screen video isn t a codec or a format . Flash only supports the 3 codecs noted . Flash Lite for mobile-devices also allows playback of device video 3gpp etc if the device has native codecs but that s different from Flash having built-in support . Comment : @fenomas thanks for pointing that out .

You cannot convert a container to an endoding . Comment : @Rikus Honey Did you enable libvo-aacenc like this --enable-libvo-aacenc . Why don t you use libfaac or libfdk aac . They are free . .. . Answer : I suggest you first check whether your .mkv file already has H.264 AAC streams in the first place .

Comment : You can use -codec copy or -c copy instead of -vcodec copy -acodec copy .

The only format it can handle is the matroska container with h264 coded content . Comment : So the desired output is an mkv . Is your input an mp4 or another mkv I see conflicting info in your description and sample code . If all you re trying to do is convert mp4 to mkv that s something GStreamer can do but the pipeline will vary depending on whether you want to add the audio tracks and perhaps some other factors . Are you doing the conversion in Windows or in Linux Also what created the input video It may be the problem if ffmpeg couldn t handle it . Note that RTP RTSP really only deals with the streaming side of things . It doesn t affect the correctness of mp4 mkv files . Comment : @mpr Sorry I accidentally changed the format when I changed the name . Changed it and added more info to the question that should cover your questions in the comments . I m trying to change the format from .mp4 to .mkv . Running a Windows 7 with ffmpeg and gstreamer built for windows . A digital camera produces input.mp4 with audio . I don t want the audio in output.mkv . .. . Answer : So this question can go in a whole bunch of different directions depending on what you re trying to do . Here is a very basic pipeline that just re-muxes h264 video data in an mp4 file into an mkv file . It ignores the audio . No re-encoding is necessary . gst-launch-0.10 filesrc location bbb.mp4 qtdemux video x-h264 h264parse matroskamux filesink location tmp bbb.mkv .. . .. . Here is another pipeline that demuxes an mp4 file re-encodes it using the out-of-the-box x264 settings and re-muxes it into an mkv file . gst-launch-0.10 filesrc location bbb.mp4 decodebin2 videoconvert x264enc h264parse matroskamux filesink location tmp bbb2.mkv .. . .. . Video formats are usually more like a bundle of data than an individual file . A the top level you have your container formats mp4 mkv etc . then often within those containers you have video and audio data stored in various formats h264 video AAC audio etc . . Then at the streaming level you have protocols like RTP RTSP is a sort of wrapper protocol for negotiating one or more RTP streams and MPEGTS . You may also want to double check what your camera is producing . You can run ffprobe on it : .. . .. . ffprobe whatever.mp4 .. . .. . You can also try creating simple test videos from scratch to see if GStreamer can even make anything your server can understand . gst-launch-0.10 videotestsrc num-buffers 120 ffmpegcolorspace x264enc profile main h264parse matroskamux filesink location tmp main.mkv .. . .. . gst-launch-0.10 videotestsrc num-buffers 120 ffmpegcolorspace x264enc profile baseline h264parse matroskamux filesink location tmp baseline.mkv .. . .. . gst-launch-0.10 videotestsrc num-buffers 120 ffmpegcolorspace x264enc profile high h264parse matroskamux filesink location tmp high.mkv Comment : Seems like a great pipeline and thank you for the explanation .

Thanks EDIT : I want the new file to be a smaller file size than the original and go in another folder while leaving the original file can this be done with ffmpeg Comment : you should take a look to at ffmpeg : ffmpeg.org https : www.ffmpeg.org .. . Answer : After installing ffmpeg https : www.ffmpeg.org put this line on a bat file on the same folder of the .mkv files . this command is just changing the video containers so you are copying the video codec and audio codec and nothing is being re-encoded as said here http : askubuntu.com questions 396883 how-to-simply-convert-video-files-i-e-mkv-to-mp4 .

I am working on what may eventually become a Minimalist Media Server for Local Area Networks with option to launch files to Chromecast . It was prompted by a discovery that there are no UPnP DLNA client Chrome apps or easy media access methods for Chromebooks . While Plex works on Chromebooks Chromecast redirection only works through a Plex web link . In any case most media servers seem like a lot of unnecessary overhead and periodic disk thrashing when all that is wanted is a simple and direct way to play via wifi from a few terabytes of LAN-hosted media files . IMO thumbnails and category features etc . just get in the way of the actual viewing or listening . Enough soapbox now to the MKV and M4A file anomaly : when I click on a link-to an MKV demo video file from my web host Hostgator the browser both Chrome and Firefox starts downloading instead of playing the MKV file . When I click the link-to the same file locally Civet Web Server an open-source fork of Mongoose the MKV file plays normally in an HTML5 browser window . The opposite occurs with M4A music files . A click on a Hostgator-hosted M4A file link plays in the browser s HTML5 web player . A click on the file hosted locally prompts downloading instead of playing . So can some expert out there tell me why links to these two types of media files behave differently locally vs on the internet Is it a function of the 1 host Hostgator or 2 the web server Apache vs Civet Web Is there some mime type etc . configuration file for Apache or elsewhere that might force how MKV files are handled by my host MinMedia Local Area Network Win7 MKV links http : i.stack.imgur.com JMDsg.png Comment : Another curious finding is that by simply renaming an MKV file to MP4 it will play in the browser s default HTML5 player from both a local and internet link .

In WAWS you can use the WebJobs SDK for long running asynch processes . See asp.net aspnet overview developing-apps-with-windows-azure http : www.asp.net aspnet overview developing-apps-with-windows-azure getting-started-with-windows-azure-webjobs .. . Answer : You DON T want to use IIS ASP.Net to run a long running process it was not designed for that . Only use it for the initial call in Web.API to kick off your service by using MSMQ or inserting a row into a table that tells your separate process what to do . Create a separate application - either a Console application where you would use Windows Scheduler to periodically run the app and check for new work items or a Windows Service that periodically checks your work item store for work items . You can then use the ThreadPool etc to asynchronously run your process . Comment : With Azure WebJobs you now can add long running processes . See my tutorial asp.net aspnet overview developing-apps-with-windows-azure http : www.asp.net aspnet overview developing-apps-with-windows-azure getting-started-with-windows-azure-webjobs .", "Question : I ve created some Azure Webjobs https : azure.microsoft.com en-us documentation articles websites-webjobs-resources that use triggers and I ve just learnt about Azure Functions https : azure.microsoft.com en-us documentation services functions . From what I understand Azure Functions seem to overlap with Azure Webjobs features and I have some difficulty to understand when to choose between Function and Webjob : .. . .. . Unlike Webjobs Functions can only be triggered it hasn t been designed to run continuous process but you can write code to create a continuous function . You can write Webjobs and Functions using many languages C node.js python .. . but you can write your function from the Azure portal so it is easier and quicker to develop test and deploy a Function . Webjobs run as background processes in the context of an App Service web app API app or mobile app whereas Functions run using a Classic Dynamic App Service Plan . Regarding the scaling Functions seems to give more possibilities since you can use a dynamic app service plan and you can scale a single function whereas for a webjob you have to scale the whole web app . So for sure there is a pricing difference if you have an existing web app running you can use it to run a webjob without any additional cost but if I don t have an existing web app and I have to write code to trigger a queue should I use a webjob or a Function Is there any other considerations to keep in mind when you need to choose Comment : This is a blog post I owe . : I ll try to prepare a response but this may be a bit open ended for Stack Overflow so you may need to ask this on MSDN if it gets closed . Comment : So Chris let me know when it will be available . Cheers . Comment : Just replied . Let me know if there is anything you want more elaboration on . My wife is staring at me to leave work so it may be a bit rushed here and there . Comment : No worry it is not urgent Thanks a lot .. . Answer : There are a couple options here within App Service . I won t touch on Logic Apps or Azure Automation which also touch this space . Azure WebJobs .. . .. . This article https : azure.microsoft.com en-us documentation articles web-sites-create-web-jobs is honestly the best explanation but I ll summarize here . On Demand WebJobs aka . Scheduled WebJobs aka . Triggered WebJobs .. . .. . Triggered WebJobs are WebJobs which are run once when a URL is called or when the schedule property is present in schedule.job https : azure.microsoft.com en-us documentation articles web-sites-create-web-jobs CreateScheduledCRON . Scheduled WebJobs are just WebJobs which have had an Azure Scheduler Job created to call our URL on a schedule but we also support the schedule property as mentioned previously . Summary : .. . .. . + Executable Script on demand .. . + Scheduled executions .. . - Have to trigger via .scm endpoint .. . - Scaling is manual .. . - VM is always required .. . .. . Continuous WebJobs non SDK .. . .. . These jobs run forever and we will wake them up when they crash . You need to enable Always On for these to work which means running them in Basic tier and above . Summary : .. . .. . + Executable Script always running .. . - Requires always on - Basic tier and above .. . - VM is always required .. . .. . Continuous WebJobs with the WebJobs SDK .. . .. . These aren t anything from a WebJobs the feature point of view . Essentially we have this sweet SDK we wrote targeting WebJobs which lets you execute code based on simple triggers . I ll talk about this more later on . Summary : .. . .. . + Executable Script always running .. . + Richer logging dashboard .. . + Triggers supported along with long running tasks .. . - Requires always on - Basic tier and above .. . - Scaling is manual to set up .. . - Getting started can be a bit tiresome .. . - VM is always required .. . .. . Azure WebJobs SDK .. . .. . Azure WebJobs SDK is a completely separate SDK from WebJobs the platform feature . It s designed to be run in a WebJob but can really be run anywhere . We have customers who run them on worker roles and even on prem or other clouds though support is only best effort . The SDK is just about making it easy to run some code in reaction to some event and make binding to services etc . easy . This is honestly best covered in some docs https : azure.microsoft.com en-us documentation articles websites-dotnet-webjobs-sdk-get-started but the heart of it is that event + code nature . We ve also done some cool extensiblity work but that s secondary to the core purpose . Summary : .. . .. . Most of these are mentioned above .. . + You can extend and run whatever you want . Full control . - HTTP stuff is a little wonky but it works .. . .. . Azure Functions .. . .. . Azure Functions is all about taking that core purpose of the WebJobs SDK hosting it as a service and making it easy to get started with other languages . We also introduce the Serverless concept here because it made a lot of sense to do so - we know how our SDK scales so we can do intelligent things for you . Azure Functions is a very heavily managed experience . We aren t supporting bringing your own host . Currently we don t support custom extensions but its something we re investigating . We re opinionated about what you can and can t do but for the things we enable they are slick and easy to use and manage . Most of the framework things we ve done to improve Functions go through the WebJobs SDK though . For instance we ll be uploading a new NuGet for WebJobs which really drastically increases the speed of logging which has huge perf benefits for WebJobs SDK users . In shipping Functions as WebJobs SDK as a Service we ve really improved a lot of experience issues . + Lots of languages supported .. . + Fully managed dynamic scaling .. . + Easy to use portal w UX for managing connections etc . - Host not customizable yet .. . Runs in a separate app which requires some configuration in your repo but makes long term maintenance much easier . strike No tooling yet strike Some tooling is now in alpha - https : www.npmjs.com package azurefunctions .. . .. . I m probably biased since Functions is our latest and greatest but feel free to shoot more cons for Functions my way . I ll probably end up publishing a blog which elaborates a bit more but I tried to keep this as succinct as possible for this forum . Comment : Thanks Chris I am going to build some samples around Azure Function and let you know when I ll have a little be more experience with the product . Comment : Sounds awesome . DM me on Twitter @crandycodes if you have any questions . I can help you get your samples promoted on Azure.com if you d like as well if you want to share them . Comment : Chris I ve implemented a sample project that use web jobs to prove the benefit of using microservices over monolithic app . Should it be relevant to use azure function to create a sample that show how to deal with microservices and serverless azure functions Comment : I could see that being useful . I know there is a lot of room to discuss how to transition from server to serverless application patterns . That kind of seems related to what you just described .

Assuming you have not configured anything for the timezone your cron job should use UTC which is the default timezone in Azure . From Changing the server time zone on Azure Web Apps https : blogs.msdn.microsoft.com tomholl 2015 04 06 changing-the-server-time-zone-on-azure-web-apps you can specify the time zone you want your application to run in by making an application setting called WEBSITE TIME ZONE and set it to a proper value .

From what I understand Azure Functions seem to overlap with Azure Webjobs features and I have some difficulty to understand when to choose between Function and Webjob : .. . .. . Unlike Webjobs Functions can only be triggered it hasn t been designed to run continuous process but you can write code to create a continuous function . You can write Webjobs and Functions using many languages C node.js python .. . but you can write your function from the Azure portal so it is easier and quicker to develop test and deploy a Function . Webjobs run as background processes in the context of an App Service web app API app or mobile app whereas Functions run using a Classic Dynamic App Service Plan . Regarding the scaling Functions seems to give more possibilities since you can use a dynamic app service plan and you can scale a single function whereas for a webjob you have to scale the whole web app . So for sure there is a pricing difference if you have an existing web app running you can use it to run a webjob without any additional cost but if I don t have an existing web app and I have to write code to trigger a queue should I use a webjob or a Function Is there any other considerations to keep in mind when you need to choose Comment : This is a blog post I owe . : I ll try to prepare a response but this may be a bit open ended for Stack Overflow so you may need to ask this on MSDN if it gets closed .

My wife is staring at me to leave work so it may be a bit rushed here and there . Comment : No worry it is not urgent Thanks a lot .. . Answer : @johnnaras Yes you can create scheduled functions as you will find in the Azure Functions documentation https : azure.microsoft.com en-us documentation articles functions-triggers-bindings timer-trigger . Basically you need to modify the function.json file and add a CRON like expression or a hh : mm : ss value in the Schedule parameter . For your 30 minute triggered function it should look something like this : Comment : Jose I think you should create a new question and post your answer there because your answer is not related to this topic", "Question : I plan to use WebJobs as a lightweight substitute for NServiceBus but wanted to first verify that routine SQL Azure Database queries can be made from a triggered WebJob handler My database access will be through EntityFrameworks . This SO thread indicates that WebJobs does not support SQL Database but I hope this just means that SQL Database cannot be used as a triggering mechanism for a WebJob handler Azure Web Job - How to connect to an Azure MS SQL Database http : stackoverflow.com questions 21758043 azure-web-job-how-to-connect-to-an-azure-ms-sql-database .. . .. . I have not found a WebJob sample that issues SQL Database queries but since a WebJob has access to the same app-config as the main WebSite I assume database-connection details can be made available .. . Answer : Webjobs are any executable that can run on Azure so .NET programs will run fine . The triggering mechanism is specific and CANNOT utilize SQL Azure but you can run SQL Azure in your executable code WITHIN the webjob itself . For Example this webjob waits for the message web-jobs-testing-sql on testwebjobsqueue before executing the query on the SQL Azure database and writing the results to the text file in the configured storage container : .. . .. . Of course it would be best to store your connection-string storage container names etc . in the configuration settings of your website hosting the webjob you can do this in the app settings and connection strings sections of the configure tab in the azure portal so you don t have any settings in files accessible on the website . Comment : Thank you for the extensive code example I was hoping for positive confirmation because I want to get a pilot example of my first Azure app running without the additional burden of configuring web and worker roles plus associated costs . I should not be critical of the docs since WebJobs is in beta but I feel there is too much emphasis demonstrating how to configure WebJobs rather than how to invoke and what can be done within a WebJob . Comment : I agree but there are a few decent examples around . The one I posted is based on one of my production jobs without the SQL . Right now I m just keeping things simple while in preview and until more functionality is added but what is there will get the job done for now . I ll dig up a few more links for you and post here later . Comment : is there a way to know the IP address of the machine running the web job The reason is that I m planning to access a SQL Azure database that is protected IP filtering . Comment : @Shankar Yes the WebJobs are run on your Azure Web App instance so assuming you are not using shared instances or auto-scaling you can find the IP adresses under Properties- Outbound IP Addresses .", "Question : I have an Azure website with a production and staging slot with multiple instances . I run several Azure webjobs on the site some of which are triggered others that are continuous . I understand triggered webjobs will only run once on one instance . My current setup is : .. . .. .

I really like websites and webjobs but it seems the story related to continuous independent deployment of webjobs and websites is broken . Would really appreciate advice Thanks .. . Answer : Azure websites deployment slots are not an easy concept to understand together with WebJobs it gets a little bit more difficult . I suggest reading the following post to get a better understanding on deployment slots - http : blog.amitapple.com post 2014 11 azure-websites-slots including the comments section for useful information .. . .. . To get a better understanding on how WebJobs work and deployed see this post - http : blog.amitapple.com post 74215124623 deploy-azure-webjobs .. . .. . It is important to understand that : .. . .. . 1 . When swapping deployment slots you actually swap the content files of the website between the 2 slots . 2 . WebJobs are part of the website content . So when you swap the slot you actually swap the website files including the WebJob . Note it is a bad practice to deploy a WebJob directly and not as part of your website files repository this is probably the cause of issues you are having . To prevent WebJobs from running on the staging slot you can add an app setting called WEBJOBS STOPPED and set it to 1 in the azure portal . source https : github.com projectkudu kudu wiki Web-jobs configuration-settings . Make sure this app setting is sticky to the slot otherwise it ll propagate to the production slot . Comment : Thanks for your response Amit . I didn t know it was bad practice to deploy a WebJob directly Visual Studio Azure integration actually encourages it with a publish to Azure button in a WebJob project in VS . It seems at the very least it should not be making it that easy to follow a bad practice Is there some place I can provide that feedback to the team Git deployment was a huge win for me wrt WebJobs vs . CloudServices . This weakens the story a little bit since it means a website redeployment is necessary to update a WebJob . Comment : publish to Azure for a WebJob is the same as for a Website the problematic practice is to mix together git deployment and publish to Azure msdeploy it is best to use one deployment method . Comment : Got it do you know if i add all my webjobs to the same VS solution as my website which is git deployed when I do a commit for a change in a webjob is it going to redeploy my website even if the only update is to a webjob What about other webjobs that have not been updated I worry about how long the deployment will take if its one monolithic solution with all webjobs and a website .

Going to look for an answer . Can you please drop an answer here if you do resolve it .. . Answer : Regarding logs : .. . .. . For continuous WebJobs - Console.Out and Console.Error are routed to the application logs they will show up as file blob or table storage depends on your configuration of the application logs similar to your Website . Also the first 100 lines in each invocation will also go to the WebJob log file to ease debugging pain when the WebJob fails at startup accessible using the Azure portal but also saved on your site s file system at data jobs continuous jobName . For triggered scheduled WebJobs - Console.Out Console.Error are routed to the WebJobs specific run log file also accessible using the Azure portal and stored at data jobs triggered jobName runId . Console.Out is treated marked as INFO and Console.Error as ERROR . Regarding connection strings : .. . .. . You can access your connection strings the same as in your website using the ConfigurationManager class for WebJobs not written in .NET you can find these connection strings and app settings as environment-variables all the same as with your Website . Comment : I believe once you turn application logging on it turns itself off in 12 hours . Something to keep in mind . Comment : True for file system blob storage and table storage will not turn off . Comment : Only unfortunate thing I have noticed is that console output written during a job execution is not logged with the job itself as far as I can tell any debug output you write has to be in the exception message if you want more context around a failure case .", "Question : A very simple question : .. . Why would someone use the Azure Scheduler if Azure WebJobs are free .. . .. . I couldnt find any topic regarding azure-webjobs vs azure scheduler .. . .. . The main difference is that the webjob contains everything that the scheduler can do : .. . .. . .. . Scheduler can make HTTP calls .. . .. . WebJob can do that and more run SQL commands etc .. . Answer : 1 . Continuous jobs are monitored and if they exit they are re-executed . In this way they act more like services in your local machine . There is a module that monitors and keeps your app working . Always-ON is a feature that will help your site stay alive and hence your webjobs to continuously run . 2 . Scheduler is used to trigger the webjobs . It uses the scheduler user account not the back-end account . This way you can move out of the free tier for scheduler sign up to higher tiers to suit your needs . But essentially all the scheduler is doing is hitting an https endpoint which is public but required your auth . 3 . Triggered jobs scheduled and on demand are invoked by an https call . These calls are load balanced - much in the same way that a web app with many instances is load balanced . Continuous jobs run concurrently by default but can be set to be a singleton .", "Question : I m in the process of migrating a couple of Jobs that were previously scheduled and run through Quartz.Net to Azure Webjobs . Using Quartz.Net allowed me to have all the very compact Job Classes in the same project as the console program entry-point initializing the scheduler . Now I would like to retain that structure without having to create a discrete console-application project for each and every web job . Is there currently any way to configure a command-line argument for continuous web-job that would allow to branch internally to the correct job depending on the command-line argument .. . Answer : In Azure WebJobs one way to do this is to create a script file for each WebJob with the command-line-arguments : MyApplication.exe arg1 arg2 . Another would be to select the method to run by the current WebJob name which you can get from the environment variable WEBJOBS NAME . For triggered WebJobs there is support for command-line-arguments per run in the API but it is still unsupported by the Azure portal : https : github.com projectkudu kudu wiki WebJobs-API invoke-a-triggered-job .

Comment : @andy250 create a run.cmd file with your script it will always be the script selected to run . you won t see the env variables of a webjob on kudu console as it s not running as a webjob you can create a webjob with a script that prints out all env variables and then look at the log .", "Question : Friends .. . .. .

Answer : I have a very small website that almost do nothing by now and we are implementing webjobs to do sometime-heavy background things like loading and processing information that needs to be filtered and prepared to then be showed at the web . Everything is perfect when running in debug mode from our machine . The same code also run perfect and with high performance if I put the same code in an app and then run from an Azure Virtual Machine . But when playing with Azure Webjobs the Webjob process never uses more than 5 of the CPU available . No matter what I do . I already try to change the job configuration by modifying batch size and NewBatchThreshold but nothing change .

My ideal escenario for CPU usage in the future would be : .. . .. . 10 assigned to the website .. . 90 divided into two separate webjobs .. . .. . The problem that scenario now looks impossible as I m being restricted to something like from 3.5 to 5 of CPU usage on the webjob . Any ideas Thanks Comment : are you running multiple cores i could be wrong but i think a webjob is limited to only one core so if you re running on a 4 cores instance a single webjob will not exceed 25 of total CPU utilization you would have to deploy 4 of the same webjob on a 4 cores instance to be able to utilize all 4 cores someone please correct me if i m wrong though Comment : @minwyn Thanks for the comment . Interesting what you are saying but I was running on a single core instance to see if that was the issue but the thing is that never goes up more than 5 . I even define a test rule to scale if CPU goes over 10 and it never scale up in a single core instance . I was thinking on deploying multiple instances of the same task by creating multiple webjobs but didn t sound like a good practice or at least a practice I like as a feature .

Is there any recommended approach hopefully with examples to upgrade code from DirectDraw to newer API Or should I simply install older DirectX SDK Comment : They were moved to the Windows SDK . .. . Answer : If you use DirectDraw blit functionality then it will be quite a task to port it . In my opinion your best option is to port it to GDI . It may mean writing your own blit functions however . Failing that you could port to D3D though this will be quite a task and is really dependent on how you do your rendering . If all your rendering is performed using blits and no direct frame buffer access then it should be relatively straight forward to port it to D3D . It will also provide you with HUGE speed boosts . That said you can just get hold of the DirectDraw headers I believe they are in the Windows SDK and continue using DirectDraw . Comment : I just downloaded and installed latest Windows SDK ddraw.h is include but ddraw.lib is not there . But I m marking your answer because you pointed me to the right direction .

Now I want to show another application with its own window but the other application is hidden behind the full screen Direct Draw application when launched . I can access the other application only when I close the directdraw full screen application . Is it possible to switch to another application from a direct draw full screen application while running Is there any way we can display the other application s window on top of the full screen DirectDraw function and then resume back once the other window is closed Thanks and regards .. . Answer : I looked into this some time ago and found that the way its done is to hook the DirectDraw APIs and insert your own rendering in there . Basically after the other app is done drawing the scene and is about to present the backbuffer your code jumps in and does its own thing . I never got it working myself but that seems to be the approach . I don t think there s any easy way to do it though . One other option would be to see if the other app can run in fullscreen windowed mode . Basically no borders filling the whole screen but not technically fullscreen exclusive mode . If it supports that then you can make a topmost window which will display over top of it . Comment : Sorry I forgot to mention that the other application doesn t use DirectDraw it uses regular GDI calls . Any idea if the above is possible if the other application creates a normal window or displays a Message box Right now those are hidden behind the first application . Comment : If its just using a fullscreen window with GDI calls then try making your window topmost . See msdn.microsoft.com en-us library windows desktop http : msdn.microsoft.com en-us library windows desktop ms633545 v vs.85 .aspx for the SetWindowPos call . You can provide an argument there to make your window topmost and it ll show on top of the fullscreen window . Comment : @Nerdton I tried the SetWindowPos and other APIs but still I cant see the other window . As long as the first application using DirectDraw is full screen I cant see the other application window using GDI Comment : you said in your earlier comment that the other application doesn t use DirectDraw . now you re saying it does . The SetWindowPos with topmost will work if its a regular GDI window that happens to be fullscreen . If the app is a DirectX exclusive full screen app then SetWindowPos won t work and then you get into what I mentioned earlier and having to do DLL injection and API hooking to get your draw code inserted in that other application .", "Question : This is a follow-up to this question http : stackoverflow.com questions 4120542 whats-the-fastest-way-to-repeatedly-fill-a-window-with-rgb-data-from-an-array . I m currently writing a simple game and am looking for the fastest way to repeatedly display an array of RGB data in a Win32 window without flickering or other artifacts . Several different approaches were recommended in the answers to the previous question but there was no consensus on which would be the fastest . So I threw together a test program . The code simply displays a framebuffer on the screen repeatedly as fast as possible . These are the results I obtained for 32-bit data running in a 32-bit video mode - they may surprise some people : .. . .. . Given these figures : .. . .. . Why are many people adamant that GDI is simply too slow for this operation Is there any reason to prefer DirectDraw or Direct3D over SetDIBitsToDevice .. . .. . Here is a brief summary of the calls made by each of the Direct codepaths . If anyone knows a more efficient way to use DirectDraw Direct3D please comment . Comment : I m not an expert in this field but I would definitely run this experiment on several different types of graphics hardware before I - ahem - draw any conclusions . Comment : How are you composing the RGB data Unless you need hardware-acceleration to compose the image I wouldn t expect DirectX to be faster . It needs to be sent to the video hardware one way or another to be displayed even via GDI . With the directx approaches you are adding the extra work of creating a surface or texture . That GDI would necessarily be slower is a non sequitur . Comment : The one thing that GDI does well and has been optimized for for 20 odd years now - is moving bits around . There seems to be some kind of conventional wisdom nowadays that any API that is 20 years old must be obsolete in some way . Comment : Hi folks Paul in the end what did you end up choosing and why I m displaying and updating in real-time a large array of RGB data representing the raw memory from a process and Direct2D does not seem to be appropriate for that kind of operation since I get a very low frame-rate . .. . Answer : The reason you will hear people trounce on GDI is that it used to just be old windows API calls . The newer versions of it that were called GDI+ when I last looked at em are actually just an API placed on top of DirectX calls . So using GDI may seem fairly simple programming wise at times but adding a layer between things always slows things down . As mentioned in the response from Jerry Coffin your examples are about moving the data and that is the slow time . I am a bit surprised that DirectX is that much slower though but I can not be much more help with out digging through the DirectX documentation which has been pretty awesome for quite some time really. . Might want to check out www.codesampler.com . I have always found good starting places from him and actually while I may be insane for saying this I would swear the improvements to the DirectX SDK in doc and examples were done based on this guys work As for the DirectDraw vs Direct3D and not the GDI calls discussion . I would say go to Direct3D . I believe DirectDraw has been deprecated since 8.0 or so and 9.0 has been around for quite a long while . And at the end of the day all of DirectX is 3D it just varies on the levels of helpful 2D apis that are around but you may find you can do some very interesting things in a 2D environment when you are actually using 3D space . I had a pretty neat randomly generated lightning weapon for a space invaders clone at one time : .. . .. . Anywho hope this helped PS : It should be noted that DirectX is not always the fastest .

Use direct3d for this purpose myself just for the features it provides but the principle is almost the same.. . .. . Answer : For your purposes you can use DXGI and avoid D3D completely . You don t say how you get the data into the backbuffer but DXGI allows you to create a swapchain flip it Present and access the surfaces e.g . lock them - it s called Map now . For 3D you need the 1 versions e.g . DXGISwapChain1 . See http : msdn.microsoft.com en-us library windows desktop bb205075 v vs.85 .aspx . Note that DXGISwapChain1 is a subclass of DXGISwapChain and some vital methods such as GetBuffer are in the base interface .

I m currently writing a simple game and am looking for the fastest way to repeatedly display an array of RGB data in a Win32 window without flickering or other artifacts . Several different approaches were recommended in the answers to the previous question but there was no consensus on which would be the fastest . So I threw together a test program . The code simply displays a framebuffer on the screen repeatedly as fast as possible . These are the results I obtained for 32-bit data running in a 32-bit video mode - they may surprise some people : .. . .. . Given these figures : .. . .. . Why are many people adamant that GDI is simply too slow for this operation Is there any reason to prefer DirectDraw or Direct3D over SetDIBitsToDevice .. . .. . Here is a brief summary of the calls made by each of the Direct codepaths . If anyone knows a more efficient way to use DirectDraw Direct3D please comment . Comment : I m not an expert in this field but I would definitely run this experiment on several different types of graphics hardware before I - ahem - draw any conclusions . Comment : How are you composing the RGB data Unless you need hardware-acceleration to compose the image I wouldn t expect DirectX to be faster . It needs to be sent to the video hardware one way or another to be displayed even via GDI . With the directx approaches you are adding the extra work of creating a surface or texture . That GDI would necessarily be slower is a non sequitur . Comment : The one thing that GDI does well and has been optimized for for 20 odd years now - is moving bits around . There seems to be some kind of conventional wisdom nowadays that any API that is 20 years old must be obsolete in some way . Comment : Hi folks Paul in the end what did you end up choosing and why I m displaying and updating in real-time a large array of RGB data representing the raw memory from a process and Direct2D does not seem to be appropriate for that kind of operation since I get a very low frame-rate . .. . Answer : Jerry Coffin makes some good points . The thing to bear in mind is what the DI stands for in SetDIBitsToDevice . It stands for Device Independent . Which means you were ALWAYS at the mercy of drivers . Some drivers used to be complete rubbish and it affected the performance massively . DirectDraw suffered from similar issues as well .. . but you also had access to the hardware blitters so it was generally more useful . IHVs also tended to put more time in to writing proper drivers for DirectDraw because of its gaming association . Who wants to be the bottom of the performance pile when the hardware is quite capable of doing better These days many graphics cards can accept the bit data directly so no conversion happens . If it does need to be swizzled this is also INCREDIBLY quick in this day and age . The reason your Direct3D performance is so terrible by comparison is that Direct3D by nature of the fact it is meant to be used totally internally to the GPU uses odd and complex formats to improve cache performance and so forth . Couple that with the fact that you aren t testing like for like with DDraw and D3D by creating a texture surface locking it copying unlocking and then drawing over the back buffer via various methods . To get best performance you d be best off directly locking the backbuffer using a DISCARD lock then memcpy ing directly into the returned buffer before unlocking . This will bring your performance much closer to the SetDIBitsToDevice . I still would expect D3D to be slower than DDraw however for the reasons outlined above . Comment : Thanks for your answer . Re locking the backbuffer - I know this can be done with D3D and I ll try adding support for this to my test program . Do you know if it is also possible to lock the backbuffer in windowed DDraw Comment : Also you say that in DirectDraw it is possible to get access to the hardware blitters . Does this require any additional work beyond simply calling IDirectDrawSurface7 : : Blt Comment : Yes it IS possible . If you go to www.trueharmoniccolours.co.uk under Coding- DirectX you can see some code DirectDraw I wrote 13 years ago . In that I directly lock the back buffer and then I write directly to the backbuffer Note : these days I m well ware that I am actually writing to uncached memory in that example so it is much slower than it needs to be . And yes that is exactly how you access the hardware blitters .. . If they aren t available then it is software emulated . CPUs are so fast nowadays though that you ll likely see little difference between software and hardware blitting . Comment : I was unable to get the samples from www.trueharmoniccolours.co.uk to run on my machine but looking at the source aren t they fullscreen-only Comment : @Paul : Well it was written in DX6 . . so it would likely need a fair few modifications . You may be right on the full screen only . . its been a HELL of a long time since I wrote it I don t see why it should matter though as you are always locking an off-screen ie back buffer aren t you", "Question : null .. .

However I am told DirectDraw is deprecated in newer versions of Windows I could revert to just GDI but then it is hard to completely eliminate flicker and tearing since there is no double buffering with flipping between buffers . Should I go for Direct3D or DirectDraw Or is there some way of completely eliminating flicker in GDI If Direct3D is the answer which version of it is supported on most platforms Comment : Have you considered using a higher level library like SDL for this For example SDL supports pretty much all Windows versions and if you use it s facilities in general your game could also run on other systems like Linux or MacOS . Comment : Do you really need to support NT4 Or even 2000 I can t imagine there s much out there still earlier than XP . Comment : @Rup I don t have to but it would be fun . Lower than XP would of course be dropped first but it would be fun to support NT4 and Win95 up . Comment : I agree with thkala using a Cross-Platform library toolkit will also result in higher compatibility within the Windows-World . And Cross-Platform-Support is just a pretty big bonus you ll get with it which is imho the way to go in the modern world . Comment : @Amigable : I have to say I find your definition of fun intriguing .. . Answer : Unless you are sure you will never want to port your game to any non-Windows platform I would recommend OpenGL . It should work on all versions from 2000 upwards and some lucky NT4 or Win98 users may be able to run it but don t advertise those versions as supported . Hardware acceleration won t always work but the impact on performance won t be noticeable for a simple 2D game . And you will be able to port it reasonably cheaply to other platforms e.g . iPhone if necessary . Comment : I like it . I am considering accepting this answer . Can you double buffer and flip frames in OpenGL even on old versions Comment : @Amigable That is not specific to OpenGL . Most GPUs can do it but a few typically found in netbooks and business PCs cannot .

Array is full of Color structs each having a red green blue and alpha component . Once I get the array to the correct format I m sure the saving it to file part won t be a problem . I m fine with either using a lib for this as long as its license allows me to use it in a closed source project and works on both Linux and Windows or doing it manually if I can find a nice resource explaining how to do it . If anyone can point me in the right direction I d really appreciate it . .. . Answer : In DirectDraw you can create a surface from the data in memory by setting up certain fields in the DDSURFACEDESC structure and passing it to the CreateSurface method of the IDirectDraw interface . First you need to tell DirectDraw which fields of the DDSURFACEDESC structure contain the correct information by setting the dwFlags field to the following set of flags : DDSD WIDTH DDSD HEIGHT DDSD PIXELFORMAT DDSD LPSURFACE DDSD PITCH . Oh and this only works for system-memory surfaces so it s probably needed to add the DDSCAPS SYSTEMMEMORY flag in the ddsCaps.dwCaps field if DirectDraw won t do it by default . Then you specify the address of the beginning of your pixel data array in the lpSurface field . If your buffer is continuous just set the lPitch to 0 . Else you set the correct pitch there the distance in bytes between the beginnings of two subsequent scanlines . Set the correct pixel format in ddpfPixelFormat field with correct bit depth in dwRGBBitCount and RGB masks in dwRBitMask dwGBitMask and dwBBitMask . Then set the lXPitch to the number of bytes your pixel has 3 for RGB . It depends on the pixel format you use . Then pass the filled structure into CreateSurface and see if it works . When you create the surface this way keep in mind that DirectDraw will not manage its data buffer himself and won t free this memory once you call Release on your surface . You need to free this memory yourself when it s no longer used by the surface . If you want this pixel data to be placed in video memory on the other hand you need to create an offscreen surface in a usual way and then lock it copy your pixels to its own buffer in video memory you ll find its address in the lpSurface field and remember to take lPitch in count and then unlock it .", "Question : With GDI we have the function SetTextJustification .

Can we still use ID2D1RenderTarget : : DrawGlyphRun and be able to program D2D so we can fully justify text Maybe only DirectWrite can achieve this Then.....how . Thanks . .. . Answer : DirectDraw is able to make use of calls from the Windows GDI using IDirectDrawSurface GetDC . You acquire and release the device context as normal but through DirectDraw and not a GetDC ReleaseDC pair . In typical MSDN fashion the only page I could find relating to the original DirectDrawSurface interface was for Windows CE 6.0 . Here http : msdn.microsoft.com en-us library windows desktop gg426195 however is a link-to the current version .", "Question : I am attempting to author a single buffered windowed application using the original DirectDraw interface . This is purely for educational purposes and the just because attitude . I m playing around with the IDirectDraw interface I stress this is the original version as in DirectX 1.0 . Now the documentation contains group of tutorials on creating a back-buffer and flipping between the primary surface and the back-buffer surface . However it gives no description about writing a windowed single buffer application . In fact I can find little reference to the idea at all . There s nothing that indicates its not possible . By setting the cooperation level with to DDSCL NORMAL the application behaves within a window . Followed by creating the primary surface after success . This function also succeeds . Note that I do not create a back-buffer . However in my main loop : .. . .. . Nothing is drawn to the window at all . My original code a fullscreen buffered application correctly shows hello world in the top left-hand side of the screen and the only modifications are the tiny edits to stop the back-buffer creation and to write directly to the primary surface . If I call CreateSurface with the options for a back-buffer after calling SetCooperativeLevel with DDSCL NORMAL then it returns and error . This I understand because the documentation states : .. . .. . If you were using IDirectDraw : : SetCooperativeLevel to set the mode to DDSCL NORMAL you could create only surfaces that blit between the surfaces . Have I missed something Have I fundamentally misunderstood DirectDraw I was under the impression that using buffers was for : .. . .. . Performance benefits and .. . To prevent screen tearing . I care about neither of these right not . What can I do .. . Answer : This is perfectly achievable . What is required is a primary surface to write to and a clipper to trim the surface to the window . Create a clipper of type IDirectDrawClipper and use IDirectDrawClipper SetHWnd to match the clipper to the window . Next and then use IDirectDrawSurface SetClipper to attach the clipper to the memory controlled by the primary surface . Make sure you re-call IDirectDraw SetDisplayMode and then restore the surface each time the window changes size if you aren t locking the window size . Also remember that you are required to blit to the surface and not flip as-if you had a backbuffer .

Does anyone have experience with DirectDraw surfaces flickering when combined with Windows Forms that are in some form or other set up to be transparent I ve worked on this for weeks with no success . Thanks .. . Answer : I m sorry but I would suggest that you abandon that goal completely and try to do it some other way . DirectDraw is one way of displaying stuff on the screen and forms with regions that are created on the fly as masks from so called transparent key color are done with GDI . As I see it and would like to be proven otherwise - you won t be able to combine that two windows anyway . And you will probably get different results on different Windows depending on the version graphics card used and so on . On the other side can you hack those forms that you don t have the control over and remove TransparencyKey property from them Even with Win32 API Comment : I was afraid of something like that . Do you have an alternative idea that wouldn t clash with the GDI transparency I am able to hack the forms but that causes another problem entirely unrelated to this . Comment : Well why do you need forms over the video in the first place Do you draw something on the video surfaces with that method or it just because your app has windows that can be freely moved around Comment : The latter my application is composed of several forms that can be moved around and so any form can overlap with any other form ." ] }

Determine which service is responsible for the metric you wish to add then modify that services metrics.json file to include it . You then must restart ambari-server for the changes to be picked up . You can then use the metric in any widget you desire . Another configuration file that Ambari uses is the widgets.json file . It sits in the same directory as the metrics.json file . Some services do not have a widgets.json file defined and thus will not be able to add widgets using the services dashboard . Storm is one of these services . You can define a widgets.json for Storm and add it to the service . See the Ambari documentation on Widget Operations https : cwiki.apache.org confluence display AMBARI Enhanced+Service+Dashboard EnhancedServiceDashboard-WidgetOperations : for more details . Comment : Thanks @cjackson . I want to monitor a few counters in my storm topologies . Also i see the add Widget option only for HDFS HBASE services and not in STORM service . Comment : I ve amended my answer to explain why the STORM service doesn t have the add Widget button . Comment : Thanks . i see that change comes into effect if i change the metrics.json on ambari-server and the on server hosting the server as well under ambari-agent directory and restart the server . Is there any documentation on managing these files and how these files are copied from ambari-server to corresponding ambari-agent Comment : You should only need to modify those files at their source location which is on the ambari-server node at var lib ambari-server resources common-services service-name version or var lib ambari-server resources stacks stack version services service-name . Once you restart ambari-server these files are copied to each node in the cluster via the ambari-agent . Comment : Thanks.realized it just after my previous comment . earlier i was updating metrics.json under common-services . I see the changes when file under stacks is updated . Is there any documentation available on how to manage these files", "Question : I get the following error : .. . .. . I tried the solution of HortonWorks http : docs.hortonworks.com HDPDocuments Ambari-2.1.1.0 bk releasenotes ambari 2.1.1.0 content ambari relnotes-2.1.1.0-known-issues.html but it doesn t work . I disabled all repositories and leave only one required versions snappy but neither works . Still gives the error you have installed the 1.1.0-3.el7 version but if you look at the information for that package is not . I have installed the 1.0.5-1.el6 .. . .. . My operating-system is RHEL 7 . .. . Answer : I ve been doing some work to automate ambari clusters for CI tests and also hit this problem with rhel7 . Workaround in that HDP doc is not really possible as it needs manual intervention when install fails . Having said that I was able to come up with a workaround of some sort . Trouble really is that snappy is already in yum repos used by rhel7 itself and when ambari adds its own HDP yum repos those contain older versions for snappy and snappy-devel . Simply by removing existing snappy package wont work because ambari will install both snappy and snappy-devel . It would work if ambari would only install snappy-devel which would pull correct snappy version . Workaround seem to be by using yum version locking . You can t use yum versionlock snappy-1.0.5-1.el6.x86 64 as is because actual package has to be present from repos which doesn t exist until ambari provisions its own nodes at a time of command invocation . Thought it looks like you can manually append that package to versionlock config . When I boot a plain ami or any other rhel7 based vm I run below commands which seem to be enough for ambari cluster provisioning to succeed later .", "Question : null .. . Answer : My organization is currently using Hortonworks HDP to manage our Hadoop Cluster . The default YARN scheduler is the Capacity Scheduler . I would like to switch to a Fair Scheduler . I am completely new to HDP . In the absence of a cluster management suite this would be done by editing the yarn-site.xml and changing the yarn.resourcemanager.scheduler.class property to org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler and creating an extra fair-scheduler.xml file to specify the queue configurations as mentioned here https : hadoop.apache.org docs r2.7.1 hadoop-yarn hadoop-yarn-site FairScheduler.html and then referring YARN to that configuration by setting the yarn.scheduler.fair.allocation.file property in yarn-site.xml . Now in Ambari while it is possible to change the yarn.resourcemanager.scheduler.class property via the UI and add a new custom property yarn.scheduler.fair.allocation.file I cannot for the love of god find a way to have ambari read fair-scheduler.xml instead of capacity-scheduler.xml . So my question is How do I go about switching to the fair scheduler via Ambari There s got to be an easy way right Properties in capacity-scheduler.xml http : i.stack.imgur.com Lj6Gv.png", "Question : I m a little confused when I try to install a single node IBM Open Platform cluster using an Oracle database as RDBMS . Firstly I understand that the Hadoop part of the IBM Big Insights is not a modified version of the corresponding Apache version as HortonWorks do so when Ambari from the IBM repo offers me to use an external Oracle database I suppose it should work . I may be wrong and I can t find any oracle reference in the crappy IBM installation guide to set it up correctly only that it should work with Oracle 11g R2 .. . .. . So as I do with an equivalent HortonWorks distribution but using the binaries from IBM I set up my ambari-server with all the oracle parameters --jdbc-db oracle --jdbc-driver path to ojdbc6.jar I m using a Oracle 11g XE on Centos 6.5 supposed to be supported by IOP and I specified all the stuff I had to specify to use Ambari with Oracle Service Name Host Port .. . I created the ambari user loaded the corresponding Oracle DDL packaged with Ambari and created my Hive Oozie users as specified in the.. . Hortonworks installation guide . Well Ambari seems to work well with Oracle I can set up my cluster until the last step : .. . .. . If I configure Hive and or oozie to work with oracle validating the oracle connection is OK from the service configuration tab the review step step 8 doesn t show anything or sometimes the IOP repos it seems to be arbitrary . Trying to deploy starts the tasks preparation and implies a blocking states of the installation : I can t do anything else than dropping the database and reload the entire DDL to try again or I ll obtain lots of unexpected NullPointerException .. . If I configure Hive AND Oozie to work with an embedded MySQL the default choice keeping Ambari against Oracle everything works fine . Am I doing something wrong Or is there any limitation to configure IBM Open Platform Hive and Oozie to use Oracle 11 when it works with the HortonWorks - same apache version - and Cloudera Distribution .. . .. . Of course log files don t tell me anything.. . .. . .. . UPDATE : .. . .. . I tried to install IOP 4.1 firstly using MySQL as my Ambari Hive and Oozie database everything was fine . Next I tried to install IOP 4.1 with Oracle 11 XE as external database I configured oracle created ambari hive and oozie oracle users and loaded the Ambari Oracle schema given with IOP 4.1 and I configure the same cluster as the first time specifying the Oracle particularities for Hive Oozie and Sqoop Oracle driver . Before deploying the services to all the nodes Ambari is supposed to resume what it is going to install but it doesn t : sometimes it doesn t show anything sometimes it shows only the IOP repos urls . Next trying to deploy it starts the preparation tasks but never ends . and that s it . No message no log nothing it just get stucked . As the desired components of IOP 4.1 are in the same version in HDP 2.3 Ambari 2.1 Hive 1.2.1 oozie 4.2.0 hadoop 2.7.1 pig 0.15.0 sqoop 1.4.6 and zookeeper 3.4.6 I tried to configure exactly the same cluster with HDP 2.3 Oracle 11 XE .. . and everything worked . I noticed that HDP 2.3 forces me to use SSL while IOP does not . HDP works with an Oracle JDK 1.8 by default while IOP actually offer to use an OpenJDK 1.8 instead . I don t know if it matters I ll try to be sure.. . I ll take pictures of the Ambari screen when it blocks and copy the log traces even if there s no error message.. . If anyone got an idea please share it Thanks Comment : Please share details of what is failing when it is failing etc . Also including error messages helps people troubleshoot for you . Comment : I tried to add some details . I ll take pictures trying another installation and I ll update my question . Thanks .. . Answer : Trying to operate the same installation using the Oracle JDK 1.8 everything works fine . I don t know if there is any restriccion using the Oracle JDBC driver with OpenJDK 1.8 but using Oracle 11 XE with IOP 4.1 + Oracle JDK 1.8 works .", "Question : How can I grant permissions to specific users to run ambari-server Currently I get .. .

Answer : It is only for performance . Refer the JIRA https : issues.apache.org jira browse AMBARI-5707 .. . .. . Couple of issues with Ambari-metrics .. . .. . When you are using Ambari Metrics ensure that you make it distributed so that there will not be any bottle-neck . Ambar-metrics stores the data in HBase and sometimes you may see loging to Ambari UI is very very slow . When you face such issues then you need to restart the HBase Ambari Metrics . However Ambari-metrics is better than Nagios Ganglia Comment : Why is it better than Nagios and Ganglia Also is Amabari metrics using Nagios under the hood Comment : Ambari Metrics uses a light weight process and write the data to HDFS rather then Linux FS . Hence it will scale . Please check the Jira first comment that gives some idea of it.We get rid of the writing to FS and then reading back the data in response to the call from GangliaPropertyProvider instead we use a lightweight wire protocol to push metrics to a collector service which writes it to a local key-value store e.g . : LevelDB as well as to a pluggable Storage service-layer .", "Question : null .. .

Answer : If starting from scratch to create a WSDL first web service then I definitely would recommend sticking with JAXB 95 of the time maybe even higher . It s definitely the best tested databinding in CXF and performs quite well . Where the other databindings come in are usually for one of two cases : .. . .. . 1 Java first use cases where you have something already written in Java that you want to expose as a web service with little to no modifications to the code . Aegis has it s strengths here as it s designed to be able to handle a wider range of things than JAXB . However if you CAN modify the code adding JAXB annotations usually isn t that hard . If you have mostly normal beans it s not a big deal . 2 Existing applications that use a particular mapping . If you have exising applications that are expecting XMLBeans beans or SDO beans if using 2.3-SNAPSHOT of CXF or JiBX beans if following the GSoC project then using the other databindings could help by removing any needed mappings from JAXB to those object models . Hope that helps a little .", "Question : I use Apache CXF with Aegis data-binding to provide a Java web service to a C client . This works in principle very well . On the C side I would like to use the more limited DataContractSerializer because it allows for collections instead of arrays .

Another variation of the same problem is returning an abstract-class but needing to send a concrete type . In WCF and .NET there is a feature called KnownTypes that handles these scenarios .

Thanks . .. . Answer : .scrollTo and by extension the SerialScroll plugin adjusts the position of the browser s scrollbar . For example document .scrollTo is great for smoothly scrolling to a different spot on your document . You can of course also adjust the scroll position of a block element with the style overflow : auto or overflow : scroll . Eyeballing the site you linked to it looks like they re not using scrollTo to achieve the animated new item behavior . Rather the containing block s style is set to overflow : hidden and the new items are created with a height of zero . Once inserted in to the page the new item s height is then animated to 75px or whatever . This might be a better approach for you to take . Assuming content is a jQuery object : .. . .. .

The scrolling takes place inside a container where the content is overflowing . Number one was straight forward enough . To acheive number two I did a fair bit of googling but didn t really find a solution even though I came across a few posts by people who were looking to do something similar . I ended up using Ben Almans jQuery hashchange event plugin http : benalman.com projects jquery-hashchange-plugin together with LocalScroll to acheive the desired result the code looks like this : .. . .. . The above code even though I m somewhat of a hack no pun intended when it comes to coding does what I want in Firefox Explorer and Opera . However I get different issues in Chrome and Safari . In Chrome basically the scroll is animated when a link is clicked but when the browsers back button is pressed it just jumps to the anchor without animating the transition . On a closer inspection though it seems like it does animate the back button once in a while but I can t get my head around why it only does it some of the time . In Safari it jumps to the anchor without animating regardless of whether a link is clicked or the back button is used . The animation worked in Safari before I implemented the hashchange event solution when the code looked like this : .. . .. . Does anyone have any ideas as to what is causing these issues in Chrome and Safari As I said I m a designer not a coder and this is really stretching my abilities so feel free to point out any mistakes I ve made in the code above regardless of whether they have nothing to do with the issue at hand or not . Also thanks to Ariel and Ben for these great plugins . EDIT : Ok so here is another weird thing when I uploaded the site to a test server that I run locally scrolling on link click works in Safari even though the exact same code doesn t work when I run it off-server .

Answer : You ll have to do 2 animations : one to reach the ancher offset and then after superscrollorama added new element for animation and recalculate the document height do the second animation to reach the correct key frame on that page that you fixed at offset 3000 of that section . Note that each section offset changes constantly so before launching the second animation we have to test that we are not scrolling till the next section again .

JBWEB000068 : message demo hello World JBWEB000069 : description JBWEB000124 : The requested resource is not available . Can somebody please tell me what am I doing wrong . .. . Answer : You mentioned JBoss 6 in you tags . Based on my experience Spring Boot Autoconfigure and JBoss 6 specifically is a no-go . If Hot Deploy is turned on or perhaps some other condition JBoss VFS performs some aggressive scanning of all jars in the war file . Once it starts to scan the classes in the autoconfigure module it will abort due to an error akin to ClassNotFoundException . If you are using Autoconfigure one solution might be to place the spring modules in the Container s lib . But this would make deployment unwieldy . I did not see this behavior on JBoss 7 nor Wildfly 8 . Comment : Actually - I am now able to successfully deploy multiple Spring Boot Applications with JBoss 6 . The key to this accomplishment was using the jboss-scanning.xml deployed in the jar to tell JBoss not to try and load every class in Autoconfigure lib . There are some other tweaks as well that I have been meaning to write up but the jboss-scanning.xml was key .", "Question : null .. .

I d advise NOT excluding the javaee.api . .. . Answer : JBoss EAP 6.x is a JEE6 implementation container . Also keep in mind that changing the bean-validation modules that are shipped with JBoss EAP6 breaks the supported bits . Bean Validation is part of JEE7 specification . You will need to upgrade to JBoss EAP7 http : www.jboss.org products eap download or use WildFly 9 or 10 http : wildfly.org downloads from the community . Both of them implement JEE7 spec which includes Bean Validation 1.1 . Comment : I know that s why I m trying to update the API version of bean-validation to 1.1 . The real problem we are having is that in bean-validation 1.0 method validation is not supported . That means that resteasy-hibernatevalidator is not blocking invalid incoming requests . Comment : I understand that s why I recommended upgrading to EAP7 or WildFly10 or 9 where you can use the features of BV 1.1 . Think of it this way when a new major JDK build is released 6 7 8 etc do you go back and add new APIs and features from JDK8 to JDK7 This is similar when you compare JEE6 to JEE7 . This has nothing to do with JBoss directly . JBoss EAP6 is certified for JEE6 which mandates Bean Validation 1.0 spec . Comment : The problem is that I cannot update to Jboss7 since it s still in beta and we have clients using jboss6 so no wildfly either . I do get your point on mixing different versions of JavaEE but in theory javax.validation is nothing more than an API . Changing the API version and the implementation behind it should work . Now the big problem is that there are possibly a number of dependant libraries which rely on bean-validation 1.0 being in-place . That s of course a problem but getting rid of bean-validation 1.0 is a first step to check if this is a feasible solution . Comment : I decided not to update the libraries . Even though it might be possible the build complexity and problems caused are far greater . Thanks . Comment : @Jeremy if you are excluding resteasy and all javaee apis then what would you get support for in terms of eap6 What if you run into a rest sevice bug and by excluding the rest apis you are not using the modules that is supported with eap .

JBoss Web 7.4.8.Final-redhat-4 - JBWEB000064 : Error report .. . .. . JBWEB000065 : HTTP Status 400 - org.codehaus.jackson.map.JsonMappingException : Can not construct instance of mybean.type from String value XYZ : value not one of declared Enum instance names at Source : org.jboss.resteasy.core.interception.MessageBodyReaderContextImpl InputStreamWrapper@5e421c2b line : 14 column : 26 through reference chain : RequestArgs request .. . .. . JBWEB000309 : type JBWEB000067 : Status report .. . .. . JBWEB000068 : message org.codehaus.jackson.map.JsonMappingException : Can not construct instance of mybean.type from String value XYZ : value not one of declared Enum instance names at Source : org.jboss.resteasy.core.interception.MessageBodyReaderContextImpl InputStreamWrapper@5e421c2b line : 14 column : 26 through reference chain : RequestArgs request .. . .. . JBWEB000069 : description JBWEB000120 : The request sent by the client was syntactically incorrect . JBoss Web 7.4.8.Final-redhat-4 .. . .. . .. . .. . Here the server version can be replaced to any costume name using -Dorg.apache.coyote.http11.Http11Protocol.SERVER MyServer parameter while starting up the server . But how to replace JBoss Web 7.4.8.Final-redhat-4 specified in title footer By creating custom error pages for each error like error 400.html error 500.html etc this can be resolved but then the actual error message that needs to be included dynamically has a challenge . Is there any easy way to just suppress any jboss version related information from all responses sent using Jboss .. . Answer : For this issue you need to configure custom error pages at JBoss EAP level . 1 . Create a custom ROOT App to provide the custom error page as follows : .. . .. . set enable-welcome-root false in standalone- .xml or domain.xml in then web subsystem . Deploy a basic ROOT.war archive with a web.xml that includes the error page for all http errors . When enable-welcome-root true the pages are served for welcome-content folder present in EAP 6 and when you hit for example localhost : 8080 what you can see is the index.html page which is present in welcome-folder . Now if you deploy custom ROOT.war you will see the custom error page you supplied .", "Question : I am working on Struts 2 framework with EAP Jboss 6 . My project session variables were stored and retrieved using HTTP Session Map . When I moved on to the Domain mode of Jboss with Clustering my session values were lost while switching between different nodes of the server . Then I configured Sticky session and stored the session values in Cookies . Even though I could able to retrieve value from cookie on the first request the HTTP session was lost . Currently I m using Apache Mod Cluster for clustering the configuration is as follows . Now searched and found something about mod-cluster https : github.com modcluster mod-cluster . In that it is mentioned to put the folder to deploy directory of a JBoss server profile . But in EAP Jboss 6.0 domain mode I don t know where is deploy directory and how to configure that mod-cluster .. . Answer : I solved session replication by configuring jboss-web.xml under WEB-INF folder as follows.. . In this case no need to use cookies to store values.. ." ] }

However it could make sense to build a platform specific UI with help of some pretty UI designer tool and then connect the UI code to the UI agnostic code that has been written in Haxe . I don t know if this could work because I couldn t find any example but maybe someone who has already written some MVC Haxe code that could be successfully connected to different platform specific UIs would like to share his experiences . Thanks . .. . Answer : You say : .. . .. . However it is still not possible to build sophisticated UIs .. . .. . Just because you haven t yet figured out how to do it doesn t mean it s not possible .. . .. . The reason it is possible is that in the Haxe ecosystem the language and compiler is extremely consistent cross-platform NME OpenFL provides a fairly strong cross-platform rendering environment HTML 5 has some quirks but the others seem fairly strong and so anything you build on top of these is going to cover a lot of platforms out-of-the-box . It s about being fairly high level - letting the compiler and the libraries take care of the platform quirks . In MVC the UI stuff is usually the V iew . For View UI frameworks check out these libraries : .. . .. . 1 . Stablex UI https : github.com RealyUniqueName StablexUI .. . NME OpenFL Cross Platform . Draws components using NME API . This is the only one I ve played with but the demo works consistently on android flash html5 native linux . Pretty impressive . 2 . HaxeUI https : github.com ianharrigan haxeui .. . NME Cross Platform . Again draws components on the stage . 3 . Prime https : github.com touch Prime .. . Drawn using Flash API . Not sure if it has been ported cross-platform yet . See also Talk Video from WWX conference http : www.youtube.com watch v UAT9RBb7wcU and Slides http : wwx-2013.prime.vc .. . .. . 4 . Guise http : www.tbyrne.org guise-unified-ui-for-haxe .. . A really innovative way of being able to either draw the UI or use native if available . Check out the blog post . 5 . Basis https : github.com Randonee Basis .. . Another attempt at wrapping native components - has iOS and Android libraries so far . Pretty cool but I haven t played with it yet . For MVC there are lots of options : .. . .. . 1 . PrimeVC mentioned above . 2 . MMVC https : github.com massiveinteractive mmvc based on the RobotLegs framework but tailored for Haxe . 3 . Lots of small options BBMVC http : bbmvc.org PureMVC http : haxe.org com libs puremvc etc .. . .. . The advantage of the MVC frameworks is that they separate your views from your application data model and logic controller . Try to spend some time familiarising yourself with one of the MVC frameworks and you ll see how you can write your apps in a way where you could use one of these and then any of the various view engines - either native or NME-rendered . It can be a fairly steep learning curve but this is how you build apps that are easily portable between different UI frameworks and easily testable so you know they will scale as the app grows in complexity . Comment : Thanks . I know those Haxe UI frameworks but they don t contain a lot of components . I would be very glad if I could use an arbitrary UI framework like wxWidgets Qt or Flex mxml and then glue the external UI on top of the model and controller classes that are written in Haxe . Would that be possible Comment : Have you come across Waxe then github.com misterpah waxe https : github.com misterpah waxe Comment : Yes but that s also a very small project that might vanish sooner or later . If it should be somehow possible I would like to use Haxe in conjunction with a large UI framework . Comment : That project is using wxWidgets which you asked about and is compatible with NME . I think someone did GTK bindings but I haven t heard in a while so they might be outdated . If you re looking for a UI framework with a lot of momentum already Haxe might not be the right choice for you . It s a great language but the community is still small so you have to be willing to live with the uncertainty for now at least", "Question : OpenFl is great but the latest version of NME http : gamehaxe.com 2014 03 06 nme-5-0-rereleased supports StageVideo .

On Android it was easy to integrate this with the Cordova app using activities the Haxe part runs as a separate activity but I am having some trouble achieving a similar result on iOS . So far I have tried to include all hxcpp generated code in my project in the same way that NME sets up the XCode project when you do nme build ios and I m calling hxRunLibrary from my code when I want the game to run . The problem is that hxRunLibrary seems to want to create its own UIApplication instance which fails with the following error since my main app is already running an instance : .. . .. . I think it might have something to do with SDL which Haxe uses for graphics .

The apps created runs fine only on high-end phone models but also runs slower than native apps . Especially when the app is booting it takes a while when the app is fully loaded . I know why this is slower because AIR is an extra application layer that translate it to native . Let me tell you about my perspective . I know that developing software that is not native being slower than native . In some situations you need native for speed graphics etc . but most of the time it is not really important does not need that all parts of the software using the hardware directly . The thing I want to achieve is to reduce developing costs by developing it once and to be able to port it to many platforms if required . I understand why there are so many languages around this is in my opinion only because they like the language want to bring something new because it is new or to bind developers to a specific platform a commercial reason . In fact there are not many differences in type of hardware or the way it is operating so why investing in new things when it brings nothing new . I want to develop code that is long lasting not bind to a platform hype or trend . For example when you have invested to write code for a specific platform let s say Window Mobile your code is useless these days . Especially in the mobile world things can change rapidly . Anyway lately I discover the existence of HaXe didn t know this exists . Sounds very promising using one language AS-like and port it to another language . A very interesting thing is that it is possible to port it to Javascript and use it for example in combination with phonegap to create mobile apps or to be able to use it on a website without it requires flash or embed it into an executable with the VM called Neko . They claim that the code it produce is faster than the original Adobe framework . I can imagine that it is faster because all elements of HaXe are blazing fast . Then I found NME didn t know this exists either and this seems to be based upon HaXe and Neko to create mobile apps for different platforms including Javascript and HTML5 . This gave me the idea to port flex projects to NME to get rid of the Adobe AIR requirement and maybe get the execution faster and to get more possibilities with the same code . Then I found as3hx and some info on Apache FlexJS formally known as Adobe FalconJS . as3hx translates the ActionScript code to HaXe code and FlexJS convert AS+XML to uneditable HTML5+Javascript code . I prefer as3hx because of the extended possibilities but don t how to implement the project after conversion end up with some hx files only . Haven t try FlexJS because it seems experimental not official and requires to update the Adobe Flex framework with the newer Apache Flex Framework 4.9 . I hesitate to update the framework in Flash Builder because I realize that I can screw up the original setup . I have a few questions before I proceed with this process : .. . .. . 1 . Is it really possible to convert a complex huge flex project to NME 2 .

If it is not possible to do this what is the point of these targets or do I miss something How is it possible that they claim to be multilingual if you cannot use it . Sounds to me a little pointless or not Comment : You need to ensure that you are using nme.display.Sprite instead of flash.display.Sprite . The nme.display.Sprite and all the nme classes that mimic the Flash API have compiler conditionals for compiling to the platform you have chosen . Comment : Allen thank you that does the trick Comment : Hello Erwinus 7 months passed on your question I am very interested to know what choice have you chosen did you wait Adobe to polish AIR performance or did you use haxe NME I already started my android app using openFL I like some one to tell me that I took the right decision as I prefered openFL over Adobe AIR . . .. . Answer : I m sorry to dash your hopes but I m dealing with the same issue of getting away from Flex and going towards HTML5 JS . You can bang your head against trying to convert your large flex application to HTML5 JS for months if you want but in the end it will be easier to just rewrite the entire thing in a library like ExtJS . Comment : I think you are right rewriting is the best and fastest way . I will do it with my own library jquery and phonegap . Also found this : StablexUI stablex.ru http : stablex.ru looks promising but i do not know if you can rely on it . And this one : ivank.net http : ivank.net based on canvas and looks incredibly good . Only one sad thing is that it is not working on my Galaxy S . Problem with the HTML JS solution and phonegap is that most of the time sound is not working on Android 2.3 . That is not a problem of phonegap but Android . Nice thing of NME is that you can also create an flash demo of it . Comment : Besides using NME to produce HTML JS the code is huge approx 500kb for a very simple app that plays a sound . Also the code produced by NME HaXe contains errors suspicious code . I don t know if i will give it a try . Comment : yea you will get much better performance if you rewrite from scratch Comment : @Erwinus code produced by NME HaXe contains errors suspicious code this sweeping statement is rather superfluous unless you can demonstrate these errors . NME html5 target is almost the entire flash runtime api inside a js file so yes it will be 500kb or so . You can also use the -minify compiler flag and make sure --dead-code-elimination is on . Haxe is actually a brilliant Type Safe OOP language to write js see a most minimal example on try.haxe.org http : try.haxe.org . You are not limited to NME with Haxe JS .

Answer : Is it really possible to convert a complex huge flex project to NME Haxe NME is not designed as an answer for an alternative to a flex mxml ui project so if you choose a flex ui you are confined to the limitations it has . NME has seen many complex as3 libraries ported so its not impossible but flex mxml requires a huge investment and some might argue that Flex isn t worth the effort myself included . http : www.aswing.org originally based on the java swing ui has both as3 and Haxe NME versions . https : github.com RealyUniqueName StablexUI and https : github.com ianharrigan haxeui are also both great options for Haxe OpenFL NME cross-platform uis . Tools like as3hx make the process of converting the most basic differences in as3 Haxe easier . It does not claim to be an absolute conversion and I have yet to see anything that can automatically convert highly complex as3 to Haxe . It is only a tool and wouldn t make use of optimizing as3 code to the more advanced and best language features of the Haxe language . Comment : As an additional tidbit to add the bulk of the Flex Framework is written in AS3 . The only MXML parts are some of the Spark Skins . The Flex Compiler will take MXML and turn it into ActionScript . All the Flex apps I have seen make extensive use of MXML . If NME can easily port ActionScript then it may be possible to work something up with the generated ActionScript from the Flex Compiler and a converted version of the Flex Framework . I know nothing about NME to judge the viability of this though . It sounds potentially like a massive undertaking . Comment : Thanks i think i skip the whole idea .

XPath xpath XPath.newInstance h : model tanx @wds for the link . .. . Answer : A few things . You really should be using JDOM 2.0.x .. . 2.0.5 is latest release . The XPath API in the 2.0.x versions is far better than the one in JDOM 1.x : see https : github.com hunterhacker jdom wiki JDOM2-Feature-XPath-Upgrade .. . .. . @wds is right about not having the correct namespace for the xforms elements too... . and that is why you XPath is working because it has the same namespace as the xhtml elements with the h prefix . Your code is likely to be broken still . Namespaces in XPaths often confuse people because every namespace in an XPath has to have a prefix . Even if something is the default namespace in the XML no prefix like your model element it has to have one in the XPath . queries with no prefix in the XPath always reference the no namespace namespace... . XPath specification : http : www.w3.org TR xpath node-tests .. . .. . A QName in the node test is expanded into an expanded-name using the namespace declarations from the expression context . This is the same way expansion is done for element type names in start and end-tags except that the default namespace declared with xmlns is not used : if the QName does not have a prefix then the namespace URI is null this is the same way attribute names are expanded .

Assuming @wds is correct and the namespace for the model element is supposed to be http : www.w3.org 2002 xforms then your namespace delcaration in your document should be xmlns http : www.w3.org 2002 xforms . But this namespace is the default namespace and the URI for the no-prefix namespace in your XPath query is . To access the http : www.w3.org 2002 xforms namespace in your XPath you have to give it a prefix fo the context of the XPath let s say xpns for xpath namespace . In JDOM 1.x you add that namespace with : .. . .. . Note how that adds the xpns to the query . Also note that I have anchored the h : html reference to the root of the document which will improve the performance of the query evaluation .

You need answer for number 5 on scale of 10 but u didn t solve 1 2 3 and 4 this is wat i try to mean . Hope you didn t try the foreach with if condition . Comment : Don t know xform xml-parsing . I tried sample xml and get the id of node like that method . But in this its not working . Comment : What you mean by one or more questions and bugs .. . Answer : The below example is the same as you expecting use it the same way I have accessed the name in a array . You are suppose to mention as instanceId Comment : I need the id of a node not the data between the nodes . Comment : so the key is your id.. . Comment : You can also use next to avoid nested foreach .. ." ] }

Answer : All BUILD references are build.prop values so you have to consider that if you are going to put this into release code you may have some users with root that have modified theirs for whatever reason . There are virtually no modifications that require using generic as the brand unless specifically trying to emulate the emulator . Fingerprint is the build compile and kernel compile signature . There are builds that use generic usually directly sourced from Google . On a device that has been modified the IMEI has a possibility of being zeroed out as well so that is unreliable unless you are blocking modified devices altogether . Goldfish is the base android build that all other devices are extended from . EVERY Android device has an init.goldfish.rc unless hacked and removed for unknown reasons .", "Question : I would like to have my code run slightly differently when running on the emulator than when running on a device .

I have an .apk of my application which loads and starts fine on the 2 pieces of hardware I have on hand both OS 4.1.2 . It then freezes up on a screen switch inside the application .

Newer versions 5+ of the OS have an Intel option and my .apk crashes immediately on start on those versions .

What s the difference between Intel and Google versions of Android that would cause such a huge difference Also why does my app have graphics on hardware but graphics vanish on the very same OS on the emulator Are there options I need to change somewhere .. . Answer : 1 . First update your SDK . 2 . Then install emulator system image you need . In SDK Manager you can find that Intel ARM Android images start from 4.0.3 . Google Intel ARM start from 4.4.2 instead . 3 . Make sure you have hardware virtualization enabled in PC BIOS because Intel images need that and they are much faster for that . 4 . Try to reinstall Intel HAXM . You can find setup in Android SDK Path extras intel Hardware Accelerated Execution Manager .. . .. . Intel ARM images use different CPU architecture . Instead Google Android images have only a different software configuration . Google images include Google services like Play Maps ecc .

Here are some example tests : .. . .. . ...and here s our code debug logs and comments removed for conciseness :", "Question : I recently discovered that the Android 2.0 SDK supports multitouch through new functions in the MotionEvent class . You can specify a pointer index when retrieving touch properties and in cases where multiple fingers are on the screen there should be multiple pointers provided . Unfortunately I only have a G1 to test on and it s running Android 1.5 and not 2.0 . Is there any way to test multitouch without a 2.0 device In the iPhone simulator you can hold down option and shift option to perform two fingered pinch and two fingered drag respectively . Is there any similar functionality in the Android emulator Is it something I should expect to see in the future or should I just suck it up and buy a new test phone Comment : Just to add : I got my hands on a Nexus One and it looks like you can only track two fingers using the current implementation . I only get 2 pointers even if more fingers are on the screen . .. . Answer : Yeah I don t believe the emulator has that same shortcut that the iphone one . In order to have true multi-touch support for the emulator your Hardware must support it HP TouchSmart . . etc . your OS must support it Windows 7 etc.. . and Java must support it and finally the emulator that Google provides in the SDK must support it . So you would need to have specific hardware the OS support is there but I don t believe java and emulator support is there . I think you just need to get a 2.0 device . It seems like the most appropriate and cheapest solution is . Also the emulator really is not that great to slow compared to an actually device especially on user input . All touch stuff should be developed and tested on an actual device . Use the emulator for automatic testing and layouts that are not supported by your physical test device ." ] }

Here s what happens in GCC 4.6.2 : .. . .. . For the ordered map I get : .. . .. . For the unordered-map I get : .. . .. . So in the ordered map all NaNs are treated the same which is what I expect although it seemed like NaN would violate the requirements . For the unordered-map however I can never retrieve an element again and all NaNs are different . This is also not what I would expect . Does the standard have to say anything on this matter Update : Thanks to the great answers below note that the std : : map will break if you insert anything else into it once a NaN is in it . I d be very grateful for comments on how other languages handle floating-point keys in associative containers . Comment : The Standard can t really have anything to say about NaNs specifically because a NaN is an IEEE concept . In other words its platform-dependant . Comment : @JohnDibling : That s a good point although the standard recognizes that numerical types may have a nan value as in limits . Comment : Consider the ordered and unordered associative containers in C++ keyed on double . Is NaN a valid key type Wrong question . The correct question is : which possible domain of the builtin less-than contains NaN .. . Answer : They are both forbidden by the standard . For the ordered associative containers the definition of strict weak order 25.4 4 says : .. . .. . If we define equiv a b as comp a b comp b a then the requirements are that comp and equiv both be transitive relations .. . equiv a b equiv b c implies equiv a c .. . .. . This fails for a 0.0 b NaN c 1.0 comp std : : less double .. . .. . For the unordered containers 23.2.5 3 says that the equality predicate Pred induces an equivalence relation on values of type Key . Equivalence relations are reflexive and std : : equal to double NaN NaN is false so equal to double is not an equivalence relation . By the way keying containers on a double is slightly scary in the same way that comparing doubles for equality is always slightly scary . You never know what you re going to get in the least significant bit . Something I ve always considered a little odd is that the standard expresses the requirements in terms of the key type not in terms of the actual key values added to the container . I believe you could choose to read this as not guaranteeing that map double int has defined behaviour at all if the implementation supports NaNs regardless of whether you actually add a NaN to an instance or not . In practice though an implementation of std : : map cannot somehow conjure a NaN out of its back pocket and try to compare it it only ever compares key values passed to the instance . So it should be OK if slightly scary provided you avoid adding NaNs . I d be very grateful for comments on how other languages handle floating-point keys in associative containers .. . .. . A few quick experiments in Python where set and dict are unordered associative containers which hold keys and values by reference suggest that NaNs are treated as objects that are unequal in value even if they re the same NaN but the same nan object can be found again by identity . As far as I ve seen the containers don t seem to be disturbed by containing multiple nans or a mixture of nans and other values : Comment : +1 for that second to last paragraph . Comment : The authoritarian tone of the answer evokes a certain accept reflex but I shall wait a bit longer : - Comment : One thing I ve left out is that if NaN is the only value that you ever add to your map then less double is a strict weak order on that value alone . It s not hard to write a function that works as a SWO on a domain of size 1 the only requirement is to return false . In fact I think it takes a NaN and two distinct normal values before it fails : with NaN and one value it should just behave as though NaN is equivalent to that value . But such maps probably aren t very interesting.. . Comment : @Steve : I think your two-element example behaves as-if NaN is equal to the other value . Neither is less than the other they are eqivalent . Which means you will never actually see the other element in the map : - Comment : @Nemo : agreed in fact I corrected the comment but I guess we crossed in the mail .", "Question : std : : unordered-map guarantees O 1 time search but how does it manage collision Cppreference http : en.cppreference.com w cpp container unordered-map claims .. . .. .

Answer : std : : unordered-map guarantees O 1 time search but how does it manage collision It uses open addressing separate chaining see here http : stackoverflow.com a 31113618 410767 . Cppreference claims .. . .. . Unordered map is an associative container that contains key-value pairs with unique keys . Search insertion and removal of elements have average constant-time complexity . .. . Assuming a situation where all the Hash codes are same how is the collision handled internally The colliding elements are added into another container holding all values that hashed to that bucket . That container is usually a linked-list but there s nothing stopping an implementation using e.g . a binary-tree . My assumption would be totally wrong if the hash code is unique to every key . In that case how is the unique hash code created where there are no collisions at all unordered-map isn t required or expected to do anything special to avoid collisions . Hash codes being unique to every key doesn t suffice anyway as collisions can be created when hash codes are masked or mod-ed into the number of buckets . What approach does std : : unordered-map s hash-function take to guarantee O 1 search This is the crux of your misunderstanding . unordered-map has O 1 performance when the hash-function does an adequate job of hashing the keys across the buckets . It may degrade to O n if the hash-function is poor or has been deliberately targeted by a malicious input of keys known to hash to the same bucket . The Standard does not require implementations to prevent that but users can supply a cryptographic hash pick a hash-function from a family at runtime or otherwise make it impractical for a malicious user - or similar inputs generally - to create many more collisions . Comment : if it uses a binary-tree it would nOt be any different than std : : map ordered as this uses binary-tree which guarantees o log n and i this is the major difference between ordered map and unordered-map Link List with amortized constant-time and O Log n . correct me if iam wrong Comment : @user2256825 : correction coming up - - unordered-map may use a list or binary-tree for values hashing to the same bucket - that shouldn t be confused with a map that only has a binary-tree and not the hash table buckets step .

FWIW some Java implementations use trees . Re as per my comment above - what did I say that caused this confusion I ve reread what I ve written above and couldn t spot anything... .", "Question : For both std : : map and std : : tr1 : : unordered-map I see from the standard that : .. . .. . References to elements in the unordered-map container remain valid in all cases even after a rehash . How are they doing that implementation-wise Are they maintaining all the entries as a kind of linked-list and then the hash-table just stores pointers to the elements .. . Answer : Yes linked lists are involved although not quite in the way you suggest . The 2011 standard says 23.2.5 para 8 The elements of an unordered associative container are organized into buckets . Keys with the same hash code appear in the same bucket . Within each bucket the elements are in a linked-list a separate list for each bucket not one big list for the whole container . When the container is rehashed the elements will be assigned to new buckets but the pointers to each element remain valid . The linked-list in each new bucket is assembled from pointers to the existing elements that end up in that bucket . Iterators are invalidated by a rehash since an iterator needs to hold pointers to both the element and its bucket so it can be stepped from the last element of one bucket to the first element of the next . The element pointer remains valid so existing pointers and references to an element are still valid but the bucket pointer is invalidated by a rehash so the iterator isn t usable . This is also why unordered containers only support forward iterators instead of the bidirectional iterators supported by the ordered associative containers . The elements of each bucket are in a singly linked-list so you can t step backwards through them .

So in the ordered map all NaNs are treated the same which is what I expect although it seemed like NaN would violate the requirements . For the unordered-map however I can never retrieve an element again and all NaNs are different . This is also not what I would expect . Does the standard have to say anything on this matter Update : Thanks to the great answers below note that the std : : map will break if you insert anything else into it once a NaN is in it . I d be very grateful for comments on how other languages handle floating-point keys in associative containers . Comment : The Standard can t really have anything to say about NaNs specifically because a NaN is an IEEE concept . In other words its platform-dependant . Comment : @JohnDibling : That s a good point although the standard recognizes that numerical types may have a nan value as in limits . Comment : Consider the ordered and unordered associative containers in C++ keyed on double . Is NaN a valid key type Wrong question . The correct question is : which possible domain of the builtin less-than contains NaN .. . Answer : This is because .. . .. . Like you said the weak total ordering required for std : : map is ok the equality or equivalence extra requirement for any hash-based container isn t ok to satisfy the key requirements for the hash unordered-map .. . .. . Seeing that for std : : map equivalence is when less a b less b a I d say all constraints are met . Comment : Yes I appreciate that but is this behaviour documented or commented on somehow in the standard Also I wouldn t say that the ordering is OK since NaN does not obey a SWO : it is not one of less greater equal when compared to anything . Comment : @KerrekSB see SGI std : : map http : www.sgi.com tech stl Map.html and click through to SGI Strict Weak Ordering http : www.sgi.com tech stl StrictWeakOrdering.html 1 page Comment : The part of SWO that NaN values fail is the transitivity of equivalence . 0 NaN and NaN 0 are both false . 1 NaN and NaN 1 are both false . Therefore 0 1 and 1 0 should both be false but they aren t . Hence the map has undefined-behavior as soon as you put a NaN in it . Arguably it even has UB earlier since the standard says that the order must be a SWO on the key type not just on the key values actually added to the map but that s quite a fine point . Comment : Hmm.. . I see : Given that NaN is never less than anything those conditions are vacuously satisfied . OK that s fine . So for map double is a perfectly legitimate key type .

Answer : Unordered doesn t mean that there isn t a linear sequence somewhere in the implementation . It means you can t assume anything about the order of these elements . For example people often assume that entries will come out of a hash map in the same order they were put in . But they don t because the entries are unordered . As for ordered by their hash value : hash values are generally taken from the full range of integers but hash maps don t have 2 32 slots in them . The hash value s range will be reduced to the number of slots by taking it modulo the number of slots . Further as you add entries to a hash map it might change size to accommodate the new values . This can cause all the previous entries to be re-placed changing their order . In an unordered data structure you can t assume anything about the order of the entries . Comment : I thought I can assume that they come out ordered by their hash value . Comment : I ve added more.. . Comment : Yes sure but still they would be ordered by their hash value . Of course if the hash value is the same for different keys the order is undefined . Comment : They aren t ordered by their hash value . All that depends entirely on the implementation . If it is open hashing they are ordered by their hash value modulo a prime if they didn t cause a collision and by their hash value modulo a prime modulo another prime if there was . If it is a chaining bucket implementation like most are the buckets are ordered on hash value modulo the number of buckets and the items in the list are ordered probably on insertion time . You can t call any of that ordered on hash value or indeed ordered in any useful sense at all . Comment : @Albert : If the hash map has 1009 slots a prime number and your two values hash to 13116 and 13118 they will end up in slots 1008 13116 1009 and 1 13118 1009 .

The IBM C C++ compiler documentation http : publib.boulder.ibm.com infocenter comphelp v9v111 index.jsp topic com.ibm.xlcpp9.aix.doc standlib stl unordered map.htm remarks that if you have an optimal hash-function the number of operations performed during lookup insertion and removal of an arbitrary element does not depend on the number of elements in the sequence so this mean that the order is not so unordered.. . .. . .. . Now what does it mean that it is hash ordered As an hash should be unpredictable by definition you can t take any assumption about the order of the elements in the map . This is the reason why it has been renamed in TR1 : the old name suggested an order . Now we know that an order is actually used but you can disregard it as it is unpredictable . Comment : Eh why was this downvoted That seemed to me so far the most correct answer . Isn t it Please those who don t think it is add some comments . Comment : See the other answers . A very common implementation orders the keys by hash Key NumberOfBuckets which is definitely not the same as ordering by hash Key . One of the important consequences is that the order can change if more elements are inserted and the number of buckets grows . If you d incorrectly assume it was hash-ordered the order would not change if you add more elements . Comment : @MSalters : that s why I wrote you have not to rely on any hash order as it is unpredictable . Comment : It may be unpredictable but - if things were as you describe them - at least the order would be stable . That means that if a precedes b now it will always do so .

Answer : Your code is unfortunately optimal for the standard-library as it currently is . The problem is that the emplace operation is designed to avoid copying not to avoid unnecessary construction of the mapped type . In practical terms what happens is that the implementation allocates and constructs a node containing the map value-type i.e . pair const Key T and then hashes the key to determine whether the constructed node can be linked into the container if this collides then the node is deleted . As long as hash and equal to are not too expensive your code shouldn t do too much extra work .

Notice that this always increases the container size by one even if no mapped value is assigned to the element the element is constructed using its default constructor .", "Question : std : : unordered-map guarantees O 1 time search but how does it manage collision Cppreference http : en.cppreference.com w cpp container unordered-map claims .. . .. . Unordered map is an associative container that contains key-value pairs with unique keys . Search insertion and removal of elements have average constant-time complexity . Assuming a situation where all the Hash codes are same how is the collision handled internally My assumption would be totally wrong if the hash code is unique to every key . In that case how is the unique hash code created where there are no collisions at all What approach does std : : unordered-map s hash-function take to guarantee O 1 search Comment : The word average is important here . The unordered-map is amortized constant not constant . .. . Answer : There was an omission from your post that is crucial to understand : std : : unordered-map has average-case O 1 search . It can take up to O n in the number of elements in the map to retrieve the element . As for which hash-function it uses - this is up to the user . By default it uses std : : hash http : en.cppreference.com w cpp utility hash . The only requirement on the hashing function with respect to collision handling is .. . .. . Hash functions are only required to produce the same result for the same input within a single execution of a program this allows salted hashes that prevent collision DoS attacks . cppreference Comment : Please explain the downvote .

Answer : Taken from here - Introduction to Time Complexity of an Algorithm http : careerbaba.in 2014 01 introduction-to-time-complexity-of-an-algorithm .. . .. . 1 . Introduction .. . .. . In computer-science the time-complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the input . 2 . Big O notation .. . .. . The time-complexity of an algorithm is commonly expressed using big O notation which excludes coefficients and lower order terms . When expressed this way the time-complexity is said to be described asymptotically i.e . as the input size goes to infinity . For example if the time required by an algorithm on all inputs of size n is at most 5n3 + 3n the asymptotic time-complexity is O n3 . More on that later . Few more Examples : .. . .. . 1 O n .. . n O n2 .. . log n O n .. . 2 n + 1 O n .. . .. . 3 . O 1 Constant Time : .. . .. . An algorithm is said to run in constant-time if it requires the same amount of time regardless of the input size . Examples : .. . .. . array : accessing any element .. . fixed-size stack : push and pop methods .. . fixed-size queue : enqueue and dequeue methods .. . .. . 4 . O n Linear Time .. . .. . An algorithm is said to run in linear time if its time execution is directly proportional to the input size i.e . time grows linearly as input size increases . Consider the following examples below I am linearly searching for an element this has a time-complexity of O n . More Examples : .. . .. . Array : Linear Search Traversing Find minimum etc .. . ArrayList : contains method .. . Queue : contains method .. . .. . 5 . O log n Logarithmic Time : .. . .. . An algorithm is said to run in logarithmic time if its time execution is proportional to the logarithm of the input size . Example : Binary Search http : en.wikipedia.org wiki Binary search .. . .. . Recall the twenty questions game - the task is to guess the value of a hidden number in an interval . Each time you make a guess you are told whether your guess is too high or too low . Twenty questions game implies a strategy that uses your guess number to halve the interval size . This is an example of the general problem-solving method known as binary-search .. . .. . 6 . O n2 Quadratic Time .. . .. . An algorithm is said to run in quadratic time if its time execution is proportional to the square of the input size . Examples : .. . .. .

Time complexity ignores issues on real hardware such as cache sizes memory limits and in this case the limited number of processes and the operation of the scheduler . Based on the Wikipedia page for Time complexity http : en.wikipedia.org wiki Time complexity I d say the answer is that you can t determine the runtime complexity because if it is defined as : .. . .. . Time complexity is commonly estimated by counting the number of elementary operations performed by the algorithm where an elementary operation takes a fixed amount of time to perform . Thus the amount of time taken and the number of elementary operations performed by the algorithm differ by at most a constant factor . Then we can t talk about the runtime complexity of this algorithm because time which the elementary operations take is so vastly different that the time taken would differ by more than a constant factor .", "Question : How can I properly and quite accurately evaluate program runtime and memory complexity just running program I can run program several times using different input sizes .

Answer : Although I agree with the comments on the question that time and memory complexity should be reasoned and not just only measured because of : .. . .. . Runtime not only depends on the size of the input but on the whole input and the program itself indeed look at quicksort .. . Some O complexity behaviour will only be visible after really large specific input sizes .. . .. . I still think it can be a good idea in case of doubt to do a quick measurement to validate your reasoning . Regarding the time-complexity : .. . .. . Start with input size e.g . 10 . This will take for example a total amount of T0 . Then give your program input with size 20 . This will take for example a total amount of T1 . Then give your program input with size 40 . This will take for example a total amount of T2 . Then give your program input with size 80 . This will take for example a total amount of T3 .

If it looks like the execution-time doubles each time you double the input then your execution-time is Lineair .. . .. . If it looks like the execution-time quadruples each time you double the input then your execution-time is Quadratic .. . .. . If it looks like the execution-time is eight times as high each time you double the input then your execution-time is Cubic .. . .. . Of course the execution-time will almost never be exactly the double or quadruple but the thing about these N-time is that you give an estimation of the behaviour when you are going towards an infinitely big input", "Question : I was implementing Longest Common Subsequence problem in C .

Answer : Can these two algorithms really be said to both run in O 1 Absolutely yes . Any algorithm that runs in under a fixed amount of time independently of the size of its input can be said to be O 1 . If so is there a measure that distinguishes the two It seems the first one ought to be better in some way What distinguishes algorithms with identical asymptotic complexity is a constant factor . This applies to algorithms of any asymptotic complexity not only O 1 algorithms . You can figure out the constant by adding up the elementary operations required to perform the computations according to these algorithms . Count operations performed outside a loop and add the count of operations inside the loop multiplied by the number of times that loop will be executed in the worst case i.e . 32 . While the two algorithms have identical asymptotic complexity the first algorithm is said to have a much smaller constant factor and is therefore faster than the second one .", "Question : What is pseudopolynomial time http : en.wikipedia.org wiki Pseudo-polynomial time How does it differ from polynomial time Some algorithms that run in pseudopolynomial time have runtimes like O nW for the 0 1 Knapsack Problem http : en.wikipedia.org wiki Knapsack problem Dynamic programming or O n for trial division http : en.wikipedia.org wiki Trial division why doesn t that count as polynomial time Comment : the link for trial division is broken now and the wikipedia entry has been removed . It would be nice if you remove that link . Comment : @NikunjBanka Oh whoops I linked to trial divisiont sic by mistake . Fixed .. . Answer : To understand the difference between polynomial time and pseudopolynomial time we need to start off by formalizing what polynomial time means . The common intuition for polynomial time is time O nk for some k . For example selection-sort http : en.wikipedia.org wiki Selection sort runs in time O n2 which is polynomial time while brute-force solving TSP http : en.wikipedia.org wiki Travelling salesman problem takes time O n n which isn t polynomial time . These runtimes all refer to some variable n that tracks the size of the input . For example in selection-sort n refers to the number of elements in the array while in TSP n refers to the number of nodes in the graph . In order to standardize the definition of what n actually means in this context the formal definition of time-complexity defines the size of a problem as follows : .. . .. . The size of the input to a problem is the number of bits required to write out that input . For example if the input to a sorting algorithm is an array of 32-bit integers then the size of the input would be 32n where n is the number of entries in the array . In a graph with n nodes and m edges the input might be specified as a list of all the nodes followed by a list of all the edges which would require n + m bits . Given this definition the formal definition of polynomial time is the following : .. . .. . An algorithm runs in polynomial time if its runtime is O xk for some constant k where x denotes the number of bits of input given to the algorithm . When working with algorithms that process graphs lists trees etc . this definition more or less agrees with the conventional definition . For example suppose you have a sorting algorithm that sorts arrays of 32-bit integers . If you use something like selection-sort to do this the runtime as a function of the number of input elements in the array will be O n2 . But how does n the number of elements in the input array correspond to the the number of bits of input As mentioned earlier the number of bits of input will be x 32n . Therefore if we express the runtime of the algorithm in terms of x rather than n we get that the runtime is O x2 and so the algorithm runs in polynomial time . Similarly suppose that you do depth-first search http : en.wikipedia.org wiki Depth-first search on a graph which takes time O m + n where m is the number of edges in the graph and n is the number of nodes . How does this relate to the number of bits of input given Well if we assume that the input is specified as an adjacency-list a list of all the nodes and edges then as mentioned earlier the number of input bits will be x m + n . Therefore the runtime will be O x so the algorithm runs in polynomial time . Things break down however when we start talking about algorithms that operate on numbers . Let s consider the problem of testing whether a number is prime or not . Given a number n you can test if n is prime using the following algorithm : .. . .. . So what s the time-complexity of this code Well that inner loop runs O n times and each time does some amount of work to compute n mod i as a really conservative upper bound this can certainly be done in time O n3 . Therefore this overall algorithm runs in time O n4 and possibly a lot faster . In 2004 three computer scientists published a paper called PRIMES is in P http : annals.math.princeton.edu 2004 160-2 p12 giving a polynomial-time algorithm for testing whether a number is prime . It was considered a landmark result . So what s the big deal Don t we already have a polynomial-time algorithm for this namely the one above Unfortunately we don t . Remember the formal definition of time-complexity talks about the complexity of the algorithm as a function of the number of bits of input . Our algorithm runs in time O n4 but what is that as a function of the number of input bits Well writing out the number n takes O log n bits . Therefore if we let x be the number of bits required to write out the input n the runtime of this algorithm is actually O 24x which is not a polynomial in x . This is the heart of the distinction between polynomial time and pseudopolynomial time . On the one hand our algorithm is O n4 which looks like a polynomial but on the other hand under the formal definition of polynomial time it s not polynomial-time . To get an intuition for why the algorithm isn t a polynomial-time algorithm think about the following . Suppose I want the algorithm to have to do a lot of work . If I write out an input like this : .. . .. . 10001010101011 .. . .. . then it will take some worst-case amount of time say T to complete . If I now add a single bit to the end of the number like this : .. . .. . 100010101010111 .. . .. . The runtime will now in the worst case be 2T . I can double the amount of work the algorithm does just by adding one more bit An algorithm runs in pseudopolynomial time if the runtime is some polynomial in the numeric value of the input rather than in the number of bits required to represent it . Our prime testing algorithm is a pseudopolynomial time algorithm since it runs in time O n4 but it s not a polynomial-time algorithm because as a function of the number of bits x required to write out the input the runtime is O 24x . The reason that the PRIMES is in P paper was so significant was that its runtime was roughly O log12 n which as a function of the number of bits is O x12 . So why does this matter Well we have many pseudopolynomial time algorithms for factoring integers . However these algorithms are technically speaking exponential-time algorithms . This is very useful for cryptography : if you want to use RSA encryption you need to be able to trust that we can t factor numbers easily . By increasing the number of bits in the numbers to a huge value say 1024 bits you can make the amount of time that the pseudopolynomial-time factoring algorithm must take get so large that it would be completely and utterly infeasible to factor the numbers . If on the other hand we can find a polynomial -time factoring algorithm this isn t necessarily the case . Adding in more bits may cause the work to grow by a lot but the growth will only be polynomial growth not exponential growth . That said in many cases pseudopolynomial time algorithms are perfectly fine because the size of the numbers won t be too large . For example counting sort http : en.wikipedia.org wiki Counting sort has runtime O n + U where U is the largest number in the array . This is pseudopolynomial time because the numeric value of U requires O log U bits to write out so the runtime is exponential in the input size . If we artificially constrain U so that U isn t too large say if we let U be 2 then the runtime is O n which actually is polynomial time . This is how radix sort http : en.wikipedia.org wiki Radix sort works : by processing the numbers one bit at a time the runtime of each round is O n so the overall runtime is O n log U . This actually is polynomial time because writing out n numbers to sort uses n bits and the value of log U is directly proportional to the number of bits required to write out the maximum value in the array .

Not exactly constant . : - I have no idea about nontrivial lowers bounds for the problem . .. . Answer : There are a few issues in your question that need to be addressed . My answer here is necessarily brief and informal . To really understand and appreciate computational complexity you ll have to study the material . Papadimitriou s book on Computational Complexity http : www.amazon.de Computational-Complexity-Christos-H-Papadimitriou dp 0201530821 ref sr 1 2 ie UTF8 qid 1463040639 sr 8-2 keywords computational+complexity is the standard book : Computational Complexity : A Modern Approach by Sanjeev Arora http : www.amazon.de Computational-Complexity-Approach-Sanjeev-Arora dp 0521424267 ref sr 1 1 ie UTF8 qid 1463040639 sr 8-1 keywords computational 20complexity might be a lighter read for getting started . Computitional complexity is usually measured with respect to the size of the input . For the K-Clique problem Does the input graph contain a clique of size K in the worst case you ll have to look at the whole graph or at least most of the graph to determine that there is no such clique . This means that the runtime of your algorithm will probably depend on the size of the graph usually measured as the number of nodes n in your graph . Informally this implies that the computational complexity cannot be constant since it dependes on the size of the input . A lower complexity bound is an asymptotic lower-bound i.e . any algorithm solving the problem has to have at least that computational complexity . So O 1 is actually a formally correct answer though it doesn t provide much value . A tight lower-bound is the highest asymptotic bound that is still a lower-bound . The K-clique desicion problem is NP-hard and thus it is very unlikely that a polynomial-time algorithm for the problem exists .

Answer : I m with Jordan except that I think the wall-clock-time complexity is better expressed as O 2 m where m is the size of each item rather than O max input . If each item has size m the largest item will have the integer value 2 m minus one but nobody cares about that . By construction the algorithm requires the set-up time to be smaller than 1 a constant . So wall-clock-time complexity O 2 m operation-count complexity O n . A modified algorithm taking into account set-up time would likely have wall-clock-time complexity O 2 m + n . For instance it could note the current time at the beginning calculate base time start time + k len list for some appropriate constant k then have the threads sleep until time base time+i . Then k len list is clearly O n and i is O 2 m as before for a total of O 2 m+n .", "Question : Given this sort algorithm how do you express its time-complexity strike Originally presented here http : dis.4chan.org read prog 1295544154 strike partial archive https : bl0ckeduser.github.io sleepsort sleep sort trimmed.html .

Answer : Update : I ve come back to the conclusion that O m+n where n is the length of the list and m is the largest element in it is actually sound . Original answer follows . .. . .. . justinhj s answer is quite good but I don t believe he s right in saying that you can t determine the runtime complexity . Remember when calculating worst-case time-complexity that it is worst-case time-complexity . You may not make any assumptions about the size of the input you must consider it to be infinitely large . Infinite in what way depending upon the type of the input and how it is used you want to consider what will take the longest so in some cases where the inverse is taken this infinite may be instead something approaching zero rather than infinity . For something taking a list that will generally be a list with infinitely many items . For something taking a number that will generally be hereafter inf . By this correct reasoning those answers that suggest O max input + n are faulty . But still it is possible to calculate the complexity whether it is useful or meaningful or not . When considering this algorithm clearly the item which is causing problems is sleep . The rest is easy to calculate it ends up at O n+sleep with the knowledge that it doesn t matter how many times you re running sleep their times will be independent time-complexity careth not for a dodgy task scheduler or a maximum number of processes which can be run or running out-of-memory or else you could easily call everything O 1 . But what is sleep s time-complexity Remember you must consider the input which will take the longest . That is for sleep an infinitely large number . Thus sleep is with constants still in O inf . Then the important question : is inf a constant If it is then sleep is O 1 if it is not sleep is still O inf . Whichever it is there can be no simplification of the complexity of sleep as it appears in the main algorithm as the inputs must be assumed to be infinitely large . So which is it Is inf a constant or not I present you then with two possible answers for the time-complexity of sleepsort.bash : .. . .. . O n if inf is a constant .. . O inf+n if inf is not a constant .. . .. . Which will you go with For myself I think I prefer the former . Comment : I don t understand the reasoning behind rejecting the max input term . Where did the inf come from Why would one want to sort infinite numbers They are not even comparable . : Comment : @Rotsor : b inf comes from the fact that for sleep Big O notation describes the limiting behavior of the function when the argument tends towards .. . infinity http : en.wikipedia.org wiki Big O notation . Are you happy that sleep is O inf O 1 if inf is constant a I reject max input on the same grounds : you must consider infinite data . It is invalid in Big O notation to consider non-infinite data in this way . You must use the greatest max input . c I couldn t care less that you won t be dealing with infinite numbers but that s what Big O notation requires . Comment : If you follow the same reasoning you d have to reject n too You must use the greatest n which is infinity . Working with infinity values brings us nowhere . We may only work with limits . And the claim of O n + max input as n - inf input i - inf is sound although questionably correct . Comment : And no I m not happy that sleep is O inf O 1 because sleep m takes O m time .

Other noticable changes occur as message sizes approach and exceed the various memory cache sizes : typically 32 KB for the level-1 cache L1 256 KB for the L2 and 4 8 or even 20 MB for the L3 cache in order from fastest to slowest . Un-cached memory accesses are even slower . In mattkeo s case the hashing would have found the caches warm that is a lot of the data would still have been in the cache as long as the data didn t exceed the cache size significantly . The difference between a warm cache and un-cached memory tends to be more noticeable than for a lukewarm or cold cache with a poor hit rate . Comment : I think complexity can be considered as linear not step function . More explanations in my answer below Comment : The complexity is linear but the run time is a step function because the actual number of bits or chunks processed is a step function of the input size . But I agree with your assessment that this effect should be negligible for the huge block sizes in the later test . I d overlooked the size factor completely .

I would really like to know about its complexity though . Please help me regarding this as-if it is in polynomial time then I would have proved P NP Comment : I think you should describe your algorithm here not just point to external site . Comment : No offense but you should probably learn more CS if you re trying to take on P vs NP . Whatever the answer is it s not going to be this easy . .. . Answer : As the description of your algorithm states .. . .. . this method may take considerable amount of time as every time the number of rows might get multiplied by 2 This comes out to be 2m where m is number of clauses .. . .. . Hence the worst-case running time of the algorithm is exponential not polynomial . You are hoping that in many cases the running time will be shorter due to happy coincidences in the input but worst-case running time is how the P vs NP question is assessed .", "Question : I am currently learning about Big O Notation running times and amortized times . I understand the notion of O n linear time meaning that the size of the input affects the growth of the algorithm proportionally...and the same goes for for example quadratic time O n2 etc..even algorithms such as permutation generators with O n times that grow by factorials . For example the following function is O n because the algorithm grows in proportion to its input n : .. . .. . Similarly if there was a nested loop the time would be O n2 . But what exactly is O log n For example what does it mean to say that the height of a complete binary-tree is O log n I do know maybe not in great detail what Logarithm is in the sense that : log10 100 2 but I cannot understand how to identify a function with a logarithmic time . Comment : A 1-node binary-tree has height log2 1 +1 1 a 2-node tree has height log2 2 +1 2 a 4-node tree has height log2 4 +1 3 and so on . An n-node tree has height log2 n +1 so adding nodes to the tree causes its average height to grow logarithmically . Comment : One thing I m seeing in most answers is that they essentially describe O something means the running time of the algorithm grows in proportion to something . Given that you asked for exact meaning of O log n it s not true . That s the intuitive description of Big-Theta notation not Big-O . O log n intuitively means the running time grows at most proportional to log n : stackoverflow.com questions 471199 http : stackoverflow.com questions 471199 what-is-the-difference-between-n-and-on 471206 471206 Comment : Related stackoverflow.com questions 487258 http : stackoverflow.com questions 487258 plain-english-explanation-of-big-o 487278 487278 Comment : I always remember divide-and-conquer as the example for O log n Comment : @Ethan : It doesn t matter which base you are in since base-conversion is just a constant multiplication The formula is log b x log d x log d b . Log d b will just be a constant . .. . Answer : O log n refers to a function or algorithm or step in an algorithm working in an amount of time proportional to the logarithm usually base 2 in most cases but not always and in any event this is insignificant by big-O notation of the size of the input . The logarithmic function is the inverse of the exponential function . Put another way if your input grows exponentially rather than linearly as you would normally consider it your function grows linearly . O log n running times are very common in any sort of divide-and-conquer application because you are ideally cutting the work in half every time . If in each of the division or conquer steps you are doing constant-time work or work that is not constant-time but with time growing more slowly than O log n then your entire function is O log n . It s fairly common to have each step require linear time on the input instead this will amount to a total time-complexity of O n log n . The running time-complexity of binary-search is an example of O log n . This is because in binary-search you are always ignoring half of your input in each later step by dividing the array in half and only focusing on one half with each step . Each step is constant-time because in binary-search you only need to compare one element with your key in order to figure out what to do next irregardless of how big the array you are considering is at any point . So you do approximately log n log 2 steps . The running time-complexity of merge sort is an example of O n log n . This is because you are dividing the array in half with each step resulting in a total of approximately log n log 2 steps . However in each step you need to perform merge operations on all elements whether it s one merge operation on two sublists of n 2 elements or two merge operations on four sublists of n 4 elements is irrelevant because it adds to having to do this for n elements in each step . Thus the total complexity is O n log n . Remember that big-O notation by definition http : en.wikipedia.org wiki Big O notation Formal definition constants don t matter . Also by the change of base rule http : en.wikipedia.org wiki Change of base formula for logs Changing the base for logarithms the only difference between logarithms of different bases is a constant factor .

See if that gets you anywhere Comment : @daven11 : it s exactly what I did before posting : - They get updated maybe the problem is in the animation Comment : sorry to state the obvious - difficult to tell how experienced developers are on here . I haven t used the CoreLocation framework so good luck .. . Answer : Consider latitude as x and longitude as y for now . Pre-requisites : .. . .. . 1 . Destination location must be known . 2 . Current location must be known . I would show you how to calculate the angle towards the direction now . It is as follows 1 . Get the current location and destination location s latitude and longitude . Pseudo Code : .. . .. . Let currentLocation lat long .. . Let destinationLocation lat long .. . angleTowardsDestination 2 . Calculate the base and hypotenuse for Pythagorus theorem . Now base currentLocation.lat - destinationLocation.lat 2 - currentLocation.long - currentLocation.long 2 .. . hypotenuse currentLocation.lat - destinationLocation.lat 2 - currentLocation.long - destinationLocation.long 2 .. . .. . .. . 3 . Calculate the angle now angleTowardsDestination Cos-1 base hypotenuse .. . .. . And that s the angle you need in degrees . Feel free to convert it to radian if needed . Kind Regards .. . Suman Adhikari Comment : maybe I found what s wrong in the code : in the last function body direction must be cast to CGFloat and there s no need to convert it to radians . Thanks anyway for your comment : - Comment : Your Welcome . And good luck with your project . Do write an update on what worked for you It can help someone in the future . Comment : of course my friend", "Question : I am trying to build and run the WhereamI.app example of the Big Nerd Ranch book : iOS Programming chapter4 . Compiling works just fine and it runs but the output to console is : server did not accept client registration 68 instead of providing the current GPS position and altitude . I am runing Xcode 4.1 on OS X Lion with the 4.3 SDK . There is nothing fancy at all in the code . JUst and instance of Corelocation manager and a simple delegation to WhereAmI.app .. . .. . Any clues .. . Answer : Like Brian Liang I don t think the code offered in the big nerd ranch forums is a fix per se because if you use that code you eliminate not only the application crash server did not accept client registration 68 you also render the application useless because the workaround overrides the method that a delegate for CLLocationManager would use to be aware of location updates overrides it in a way that basically says always update the location to lat : 42 long : -50 . So the forum code snippet mentioned here does eliminate the application crash but it makes all location updates amount to the same coordinates so you really can t use the application anymore . Not a fix in any grander sense of the word . Kind of let down really . Maybe this is just a simulator problem and not an issue on an actual phone Comment : Also if you use the forum hack update the lat and long to match the front door of apple headquarters so when you place your first annotation it shows up on the screen so you see it is working . I used initWithLatitude : 37.33165 longitude : -122.03075 and when I hit return for the first annotation a red pin pops up right next to the blue blinking apple headquarters location . Then also if you scroll away from apple headquarters and place another pin the map will center you back near apple headquarters so you can see the relocation feature in action too .", "Question : Prior to iOS 4.0 CoreLocation was reporting altitude correctly now it always reports as 0 ft . .. . .. .

I was expecting that they will return the same values . The difference is most notable when I start the app from a resting position face up in a table and then lift the device up in to the air . b If there is a difference when should I use the magnetic field from Core Location heading and when should I use the magnetic field from Core Motion Note : I also am not sure if the magnetic field of Core Location and Core Motion refer to different magnetic field concepts .

Comment : Are you using the magneticHeading property of the CLHeading Comment : @ThomasW No sir I m using CLHeading s x y and z . .. . Answer : To unravel this I ve spent a bit too much time digging through the Apple docs . There are three ways of obtaining magnetometer data .. . .. . 1 Core Motion framework http : developer.apple.com library ios documentation CoreMotion Reference CoreMotion Reference index.html .. . CMMotionManagers s CMMagnetometer http : developer.apple.com library ios documentation CoreMotion Reference CMMagnetometerData Class Reference Reference.html apple ref doc c ref CMMagnetometerData class .. . .. . 2 Core Motion framework .. . CMDeviceMotion http : developer.apple.com library ios documentation CoreMotion Reference CMDeviceMotion Class Reference Reference.html apple ref doc c ref CMDeviceMotion CMCalibratedMagneticField property .. . .. . 3 Core Location framework https : developer.apple.com library IOs documentation CoreLocation Reference CLLocation Class CLLocation CLLocation.html .. . CLLocationManager s CLHeading .. . .. . 1 supplies raw data from the magnetometer . 2 and 3 return derived data . The numbers in both cases are similar though not exactly the same . Difference between Core Motion s CMMagnetometer and CMCalibratedMagneticField .. . .. . 1 and 2 - both from the Core Motion framework - differ as follows : .. . .. . CMDeviceMotion Class Reference .. . .. . Discussion .. . The CMCalibratedMagneticField returned by this property gives you the total magnetic field in the device s vicinity without device bias . Unlike the magneticField property of the CMMagnetometer class these values reflect the earth s magnetic field plus surrounding fields minus device bias . CMMagnetometer gives us raw data CMCalibratedMagneticField is adjusted data . Difference between Core Motion s CMCalibratedMagneticField and Core Location s CLHeading .. . .. . The docs are not immediately clear on the difference between 2 and 3 but they do generate different numbers so let s do some digging . Core Location framework .. . CLHeading .. . .. . From Location Awareness Programming Guide http : developer.apple.com library ios documentation UserExperience Conceptual LocationAwarenessPG GettingHeadings GettingHeadings.html apple ref doc uid TP40009497-CH5-SW1 .. . .. . Getting Heading-Related Events .. . .. . Heading events are available to apps running on a device that contains a magnetometer . A magnetometer measures nearby magnetic fields emanating from the Earth and uses them to determine the precise orientation of the device . Although a magnetometer can be affected by local magnetic fields such as those emanating from fixed magnets found in audio speakers motors and many other types of electronic devices Core Location is smart enough to filter out fields that move with the device . Here are the relevant CLHeading raw properties .. . .. . The geomagnetic data measured in microteslas for the x y z -axis . read-only .. . This value represents the x y z -axis deviation from the magnetic field lines being tracked by the device . older versions of the docs add : The value reported by this property is normalized to the range -128 to +128 . I am not clear how a microtesla measurement can be normalized compressed clipped to a range of + -128 and still represent the unit it claims to measure . Perhaps that s why the sentence was removed from the docs . The units on an iPad mini do seem to conform to this kind of range but the iPhone4S gives CMMagnetometer readings in higher ranges eg 200-500 . The API clearly expects you to use the derived properties : .. . .. . which give stable N S E W compass readings in degrees 0 North 180 South etc . For the true heading other Core Location services are required geolocation to obtain the deviation of magnetic from true north . Here is a snippet from the CLHeading header file .. . .. . Core Motion framework .. . CMDeviceMotion CMCalibratedMagneticField .. . .. . CMMagnetometer .. . .. . CMMagneticField .. . This is the struct that holds the vector . It s the same for CMDeviceMotion s calibrated magnetic field and CMMagnetometer s uncalibrated version : .. . .. . .. . .. . The difference between 2 and 3 are hinted at here : .. . .. . Core Location CLHeading .. . .. . Represents a vector pointing to magnetic North constructed from axis component values x y and z .. . .. . Core Location is smart enough to filter out fields that move with the device .. . .. . Core Motion CMCalibratedMagneticField .. . .. . represents Earth s magnetic field plus surrounding fields without device bias .. . .. . So - according to the docs - we have : .. . .. . 1 CMMagnetometer .. . Raw readings from the magnetometer .. . .. . 2 CMDeviceMotion CMCalibratedMagneticField magneticField .. . Magnetometer readings corrected for device bias onboard magnetic fields .. . .. . 3 CLHeading x y z .. . Magnetometer readings corrected for device bias and filtered to eliminate local external magnetic fields as detected by device movement - if the field moves with the device ignore it otherwise measure it .. . .. . Testing the theory .. . .. . enter image description here http : i.stack.imgur.com 32Tgu.png .. . .. . I have put a Magnet-O-Meter demo app on gitHub https : github.com foundry MagnetoMeter which displays some of these differences . It s quite revealing to wave a magnet around your device when the app is running and watching how the various APIs react : .. . .. . CMMagnetometer doesn t react much to anything unless you pull a rare earth magnet up close . The onboard magnetic fields seem far more significant than local external fields or the earth s magnetic field . On my iPhone 4S it consistently points to the bottom left of the device on the iPad mini it points usually to the top right . CLHeading . x y z is the most vulnerable responsive to local external fields whether moving or static relative to the device . CMDevice CMCalibratedMagneticField is the most steady in the face of varying external fields but otherwise tracks it s Core Location counterpart CLHeading . x y z pretty closely . CLHeading.magneticHeading - Apple s recommendation for magnetic compass reading - is far more stable than any of these . It is using data from the other sensors to stabilise the magnetometer data . But you don t get a raw breakdown of x y z .. . .. . yellow CMMagnetometer .. . green CLHeading . x y z .. . blue CMCalibratedMagneticField .. . red CLHeading.magneticHeading .. . .. . This does seem to contradict the docs which suggest that CLHeading . x y z should be less influenced by local external fields than CMCalibratedMagneticField . What approach should you take Based on my limited testing I would suggest .. . If you want a compass reading .. . CLHeading s magneticHeading and trueHeading will give you the most accurate and most stable compass reading . If you need to avoid Core Location .. . CMDeviceMotion s CMCalibratedMagneticField seems to be the next most desirable although considerably less stable and accurate than magneticHeading . If you are interested in local magnetic fields .. . CLHeading s raw x y and z properties seem to be more sensitive to local magnetic fields . If you want all of the data including onboard magnetic fields .. . Raw magnetometer data from CMMagnetometer . There is really not much point using this unless you are prepared to do tons of filtering as it is hugely influenced by magnetic fields generated on the device itself . Comment : Will there be a difference in values if CMAttitudeReferenceFrameXMagneticNorthZVertical is changed say to CMAttitudeReferenceFrameXTrueNorthZVertical If yes why did you choose CMAttitudeReferenceFrameXMagneticNorthZVertical Comment : @MiuMiu it won t make any difference as the reference frame only affects CMAttitude roll pitch yaw etc - which I am not using in this demo .

Answer : each APP would use it s own specific UUID using the major and minor integer values to differentiate between beacons . for example the UUID would be associated with a chain of shops major would identify the shop and minor the aisle or even a group of products . scanning for unknown UUID s would not be very useful as your app would not know what to do with the information . the UUID is generated once and for all using the uuidgen command in the terminal . sadly there is no protocol to actually communicate with beacons hence there is no standard to get the location of a beacon or any other useful info . it would have been so much better if we could open a connection to a beacon usually the closest one and obtain additional data from it without having to be on the same WIFI network . you either have to use bonjour to communicate with the device over WIFI or use the major and minor id to obtain data from a webservice of some kind .

Answer : Unfortunately you cannot at this time search for an arbitrary iBeacon without first knowing the proximityUUID value . I ve tried writing directly to COREBluetooth and although you can discover and connect to transmitting beacons in your area what you get back is jibberish with no relation to the BLE UUID . So you can t even confirm that the peripheral you have connected to is in fact an iBeacon . This does not appear to be a limitation of the BLE spec rather it is a limitation that has been imposed by Apple . It also appears that this limitation does not exist for the Android platform . Until this gap is closed Android will have a significant advantage over iOS in this area . I disagree with previous comments that scanning for UUIDs would be useless . On the contrary if you knew the beacon UUID you could create a map of beacon location subject in the cloud and use it to navigate assuming the beacon was fixed using a web service . You could crowd-source the data so that eventually a very rich database of beacon UUID location pairs would be available to all who wanted to write location apps . Perhaps this is why Apple is hiding the info they may be holding this back for their own purposes .", "Question : I am working on a app that relies heavily on monitoring user visits in possibly multiple regions areas . I am currently experimenting with region monitoring which works pretty well however the location callback is not as accurate as I want it to be . I have seen CLVisit but the documentation out there doesnt explain it very well especially its use . Comment : Voodoo . It was covered in the core-location session of WWDC in 2014 - asciiwwdc.com 2014 sessions 706 http : asciiwwdc.com 2014 sessions 706 .. . Answer : I think you are misunderstanding the concept of CLVisits . There is actually no Visit object that you need to create . The CLLocationManager delegate method is triggered by the algorithm that apple has determined see wwdc lecture http : asciiwwdc.com 2014 sessions 706 for more info . This is explained in the CLLocationManager documentation https : developer.apple.com library prerelease ios documentation CoreLocation Reference CLLocationManager Class index.html apple ref occ cl CLLocationManager .. . .. . .. . Getting the Visited Locations .. . .. . In iOS the visits service provides an alternative to the significant location change service for apps that need location information about interesting places that the user visited . For example if the user is in one location for an extended period of time the service might generate an event when the user arrives at that location and another when the user leaves that location . The service is intended for apps that might already be using the significant location change service and want an even lower power way to do so . You would not use this service to create navigation apps or apps that rely on regular location updates . .. . To begin the delivery of visit-related events assign a delegate to the location manager object and call its startMonitoringVisits method . As the location manager generates visit events it delivers that information to its delegate s locationManager : didVisit : method . The event data delivered to your delegate includes only the information that occurred after you started the delivery of events . In other words if you start the delivery of events after the user arrived at an interesting location the event delivered by the system when the user departed that location would not reflect the actual arrival time . If the system terminates your app this service relaunches it when new visit events are ready to be delivered . That said if you look at this article from NSHipster http : nshipster.com core-location-in-ios-8 it references some current issues with CLVists for iOS 8.1 . It essentially goes on to say that if you want infrastructure that extremely precise don t use CLVisit . Seems like you re doing it right for now at least . CLVisit is as of iOS 8.1 not all that precise . While start and end times are generally accurate within a minute or two lines get blurred at the edges of what is and what is not a visit . Ducking into a corner coffee shop for a minute might not trigger a visit but waiting at a particularly long traffic light might . It s likely that Apple will improve the quality of visit detection in future OS upgrades but for now you might want to hold off on relying on CLVisit in favor of your own visit detection for use cases where it s vital your data is as accurate as it can be .", "Question : This question already has an answer here : .. . .. . iOS - MKMapView place annotation by using address instead of lat long questions 9606031 ios-mkmapview-place-annotation-by-using-address-instead-of-lat-long 5 answers .. . .. .

How do we do that I have read some articles like Apple s iOS 7.1 will fix a geolocation bug http : venturebeat.com 2014 02 11 apples-ios-7-1-will-fix-a-geolocation-bug-after-developer-sends-letter-to-tim-cook . But Apple didn t provide much communication related to that nor any sample code on how to get the location update even when the app is killed terminated suspended . I have read the Release Notes for iOS 7.1 https : developer.apple.com library ios releasenotes General RN-iOSSDK-7.1 index.html apple ref doc uid TP40013935 . I couldn t find anything related to that as well . So how do we actually get the location update for iOS 7 and 8 even when the app is suspended .. . Answer : After months of trials and errors by experimenting the Core Location Framework I have found the solution to get location update even when the app is killed suspended . It works well for both iOS 7 and 8 . Here is the solution : - .. . .. . If your app is a location based mobile-application that needs to monitor the location of the device when it has significant changes the iOS will return you some location coordinates when the device has moved more than 500 meters from the last known location . Yes even when the app is killed suspended either by the user or iOS itself you still can get the location updates . So in order for a locationManager to get location update even when the app is killed suspended you must use the method startMonitoringSignificantLocationChanges you can not use startUpdatingLocation . When iOS wants to return the location update to the app it will help you to relaunch the app and return a key UIApplicationLaunchOptionsLocationKey to the app delegate method didFinishLaunchingWithOptions . The key UIApplicationLaunchOptionsLocationKey is very important and you must know how to handle it . You must create a new locationManager instance when you receive the key and you will get the location update on the locationManager delegate method didUpdateLocations . Here is the sample code : - .. . .. . In addition to the didFinishLaunchingWithOptions method I have created the locationManager instance when the app is active . Here are some code examples : .. . .. . I have written an article explaining on the details on how to get the location update for iOS 7 and 8 even when the app is killed suspended . I have also uploaded the complete source code on GitHub with the steps on how to test this solution . Please visit the following URLs for more information : - .. . .. . 1 .

Not working on Device nor Simulator does anyone else experience this issue Comment : Are you testing this on a device or on the Simulator Comment : Device and Simulator . .. . Answer : If you re using startMonitoringSignificantLocationChanges which was a feature new to iOS 4.0 then you will not get altitude updates . This low-power mode only uses cell towers to figure out a user s location and this method not report altitude . More generally the iPhone has three ways of figuring out your location -- cell towers wi-fi and GPS . You will only get altitude when the GPS is being used . So even if you set your desiredAccuracy setting to be really precise to force the device to use GPS if a user is indoors the iPhone probably won t be able to get a GPS signal and will fallback to cell or wi-fi . In that case you won t get an altitude . Also consider users who are on an iPod Touch -- it only has the ability to get a location via wi-fi and thus also won t report an altitude .", "Question : I know Core Location isnt always accurate on the iPhone . Is there a way to use the location lat long along with the accuracy to then grab all of the possible suburbs streets in that area So instead of using the reverse-geocoding and having it guess the best possible suburb street is there a way to make it give an array or in some other format of all the possible suburbs streets that it could consider Thanks Comment : Hey Zac Take a look ate the comment that I have posted under yours on my answer . .. .

Take a look at the status code it is important to verify if the request was successful usually 200 or 200 and something . So how to use it VFN It is simple . on locationString is the response from Google Geocoder now you can use the info as you want . Remember to first check the status code and than parse the info . If you want only the first placemark that is selected by Google Geocoder I would suggest you to use the output in CSV that is easy to work with . If you have any queries let me know Cheers .. . VFN Comment : I have no trouble getting the street suburb city postal-code . What I want to do it use the coordinate and the radius that Core Location gives me to then get all of the streets suburbs within the radius from the coordinate . So lets say I have the coordinate -33.888068 151.205521 and an accuracy of 3km . I want to find all of the suburbs within 3km of that coordinate . Those being Chippendale Surry Hills Redfern Alexandria Eveleigh etc . Thanks for the help but it gives me the same info that I already have . Comment : Hey Zac Because of that I put the link of for the documentation on my answer . Take a look at : code.google.com apis maps documentation geocoding Viewports http : code.google.com apis maps documentation geocoding Viewports You can define the center of the region and the span for the bounding-box . The code posted above is only to illustrate in the case that you didn t know how to use the API . Let me know if it is enough . Cheers Comment : So how do I use that information to then get the suburbs Preferably in an array . Sorry i havent used XML before . Im using this : NSString stringWithFormat : @ maps.google.com maps http : maps.google.com maps geo q f f output xml ll f f spn f f quot latitude-longitude latitude-longitude location horizontalAccuracy location horizontalAccuracy Comment : Here it is how to work with XML developer.apple.com mac library documentation Cocoa Reference http : developer.apple.com mac library documentation Cocoa Reference Foundation Classes NSXMLParser Class Reference Reference.html and you can check the Apple examples at : developer.apple.com mac library samplecode ImageMap index.html http : developer.apple.com mac library samplecode ImageMap index.html apple ref doc uid DTS40009015 Comment : ok so i have been able to get it to save an array of the locations . so that is all good but while it is parsing the xml the whole UITableView is unusable . So I either need to do some sort of threading or something so that the user can still use the app while the location is being found . Is there a shorthand way with XML or do I have to get in to threading", "Question : Prior to iOS 4.0 CoreLocation was reporting altitude correctly now it always reports as 0 ft . .. . .. . Not working on Device nor Simulator does anyone else experience this issue Comment : Are you testing this on a device or on the Simulator Comment : Device and Simulator . .. . Answer : From the Core Location Data Types Reference http : developer.apple.com library ios documentation CoreLocation Reference CoreLocationDataTypesRef Reference reference.html : .. . .. . The CLLocationDistance data type the data type for altitude is a double . The formatter you are using for your stringWithFormat is an integer . You need to cast your altitude to an integer first or use a double f formatter . Comment : I am converting altitude to an integer . As I stated this worked perfectly ie . no code changed prior to iOS 4.0 . Comment : Also the way I have it gave me perfect altitude used to show for example 5280 ft . Comment : @WrightsCS have you tried the double formatter as suggested to see if that makes a difference Comment : Yes produces all 0 s .", "Question : Is there a way to manually tell the device to dispatch a significant location change-notification that will wake up any applications registered for this notification This is for testing only and I realize this private API call would get rejected upon submission to the app-store . Comment : I dug through the private framework headers and could not find anything that resembled a trigger for this . It s not convenient to only be able to test this by getting in the car and driving around with a laptop . Comment : If you use the CLLocationManager didUpdateToLocation : fromLocation : delegate then you can use startUpdatingLocation instead of startMonitoringSignificantLocationChanges for test-purpose . With no filter set inside the CLLocationManager it calls didUpdateToLocation nearly every second if you have medium-good gps-reception . For test-purpose this could help . Comment : It s not really a matter of testing the output of CLLocationManager as much as the lifecycle of the app when woken up by a significant location change . Comment : If you have an Apple Dev account you may want to take a look at the iOS5 UIAutomation . It may eventually provide you with a solution . The only road-block is I don t know if you can put a program into background mode via UIAutomation . .. . Answer : In iOS 4 you can register for significant location changes . From the Apple docs : With this service location updates are generated only when the user s location changes significantly thus it is ideal for social applications or applications that provide the user with noncritical location-relevant information . If the application is suspended when an update occurs the system wakes it up in the background to handle the update . If the application starts this service and is then terminated the system relaunches the application automatically when a new location becomes available . This service is available in iOS 4 and later only on devices that contain a cellular radio . See the Apple docs here http : developer.apple.com library ios documentation iPhone Conceptual iPhoneOSProgrammingGuide BackgroundExecution BackgroundExecution.html and here http : developer.apple.com library ios documentation UserExperience Conceptual LocationAwarenessPG CoreLocation CoreLocation.html . Here is some example code to register for signification location updates : .. . .. . .. . .. . The docs say : if you leave this service running and your application is subsequently suspended or terminated the service automatically wakes up your application when new location data arrives . At wake-up time your application is put into the background and given a small amount of time to process the location data . Because your application is in the background it should do minimal work and avoid any tasks such as querying the network that might prevent it from returning before the allocated time expires . If it does not your application may be terminated . Comment : Thanks.. . I get how it works and have been using it for some time . The question is how to test it without driving around in a car getting the device to trigger it . Comment : Ah sorry . Can I delete my answer" ] }

How do I get past this error .. . Answer : Here s how I solved the problem in case anyone out there has the same issue : I had originally installed the newer version of abcPDF without uninstalling the old version first . To get past the error here s what I did : .. . .. . Uninstalled all versions of abcPDF from the server .. . Confirmed that the GAC c : windows assembly did not contain any copies of abcPDF assemblies .. . Reinstalled the latest version of abcPDF 8.1.1.2 at time of writing .. . Confirmed that all web.config files referenced the 8.1.1.2 version of the abcPDF assembly . Once I did all of the above I was able to render PDFs without errors once again . Comment : Thank you so much for posting this fix Comment : Sure enough what I thought was an upgrade was actually a concurrent install which broke the component Your solution worked . I uninstalled all abcpdf stuff re-installed the latest and all was well", "Question : I have an HTML report with each print page contained by a div class page . The page class is defined as .. . .. . After making a few changes to my report content when I call abcPDF to convert the report to PDF suddenly I m getting a blank page inserted after every real report page . I don t want to roll back the changes I ve just made to remove this problem so I m hoping someone may know why the extra pages are being inserted . .. . Answer : I have experienced the same exact problem . the empty page is due to the page-break-after : always in the CSS . Not just ABCpdf but also the printed will spit out an extra page . So I used the following code to eliminate the last page : MyDoc.Delete MyDoc.Page .. . .. . This however lead to a different kind of a problem . On development server which has IE 8 I get an extra blank page and on production where I have IE6 I get no extra blank page . So I have emailed the support team at websupergoo to show me a way to look for a blank page . The idea is to iterate through a pdf and identify all blank pages and delete them using above logic . And I second Jakkwylde s opinion . Websupergoo folks are extremely helpful and prompt in responding . I had another problem getting ABCpdf to work under 64 bit and had spent almost a day trying to figure it out . They provided me multiple scenarios which I could try out . Their support was right on the money and I got my app up and running in minutes . Comment : Had the same problem with different IE versions on different environments .

The relevant code is : .. . .. . In debug mode theDoc.Chainable pageRef returns true when the rendering engine is MSIE but false when the rendering engine is Gecko . Suggestions for correcting this Comment : I received the following response from WebSupergoo tech support : This is a problem with Gecko 21 which ABCpdf 9 currently uses . You can reproduce the problem to see that there is only one page by using Print Preview in Firefox 21 . Since the Firefox 26 does not cause the problem this should be resolved when ABCpdf is eventually updated to use a newer version of Gecko . I ve asked them if there a Gecko-based workaround or an estimated date to the update of ABCpdf to use a newer version of Gecko will post a response when I get one . Comment : This issue is specific to the particular HTML which Eric is using . Changing the HTML is a simpler solution than updating the engine . Comment : Concur this is a problem with Firefox 21 + Bootstrap 2.3.2 + very specific HTML . I have not yet determined the pattern that is the problem . Since the bug exists in FireFox 21 Print Preview mode I ll let this lie until the next ABCpdf release comes out : - .. . Answer : We had the same problem and went looking for the specific HTML that was causing the issue . In our case it was the fact that the content that spanned several pages was in a fieldset tag http : www.w3schools.com tags tag fieldset.asp We just swapped the fieldset tag for a div tag .

Answer : I am using Version 10 of ABCpdf and I found that the style sheet path should be absolute instead of relative . I changed the stylesheet path from C : MyProject Resources Styles.css to http : www.MyDomain.com Resources Styles.css and it worked . Although version 6 seems to be working with relative paths . I didnot check it with other versions .. . .. . As per WebSuperGoo support http : www.websupergoo.com support.htm : .. . .. . Query : 6.17 .. . .. . HTML does not exist within a file and so it does not have a location . .. . External stylesheets and images are often referenced via relative URLs . Because the HTML has no location it is impossible to resolve these relative references . .. . So you need to provide your stylesheet and image links as absolute references . Or you may be able to use the HTML BASE element to specify an appropriate base location . Or you can save your HTML to file in an appropriate location and then use AddImageUrl .", "Question : null .. . Answer : I coded my version of the WebSuperGoo ABCpdf Xaml table example in an ASP.NET VB web app . Initially when calling XamlReader.Load I encountered the inner-exception : .. . .. . The calling thread must be STA because many UI components require this . I updated the code to create a thread task and then call SetApartmentState to ApartmentState.STA . The XamlReader.Load succeeded . When I call ABCpdf Doc.Save HttpResponseStream the browser opens a PDF viewer and the PDF page is blank . When I call ABCdoc.Save FilePath the PDF file contains the table as described in the Xaml file .

I m using style abcpdf-tag-visible : true to specify a tag which works using the default engine . The following code produces a blank document . Almost identical code for the default engine produces it correctly . Comment : I m having exactly the same issue . Sent an email to WebSuperGoo for support . Will update here if I get it solved.. . It was working on one server failing on another with Gecko . .. . Answer : I ve been talking to WebSuperGoo support . Found out the documentation isn t consistent complete . http : www.websupergoo.com helppdfnet source 5-abcpdf xhtmloptions 2-properties addtags.htm .. . .. . In Gecko your tag has to have a visible impact on the page for it to be picked up . In my case I had a tag that displayed a non-breaking space and thus it wasn t found . From their example changing the style to the following got it to be findable : style abcpdf-tag-visible : true border : 1px solid transparent .. . .. . Note the Border settings is what makes this work apparently . Again this fixes their demo and thus should fix Dillorscroft s example .

Thanks version 8 Comment : ABCpdf uses the version of Internet Explorer installed on the server to generate a pdf . Basically it s the printing an IE screen to a pdf file .

ABCpdf does not currently support fonts added using @font-face . So as of the 9.0 release of ABCpdf that s that . Comment : A clarification on this - ABCpdf WILL render fonts if they are installed on the machine rendering the pdf no face-face css . However if you do include font-face css it may actually break this behavior - causing it to not even embed installed fonts anymore . There I just saved you 3 days of hair pulling . Comment : Installed on the machine is the situation I want to avoid .. . I believe I covered that in my initial question . It s easy to get non-installed fonts useable by HTML Styled Text doc.AddHtml . The goal was to get them available to the Gecko engine doc.AddImageHtml . Comment : A note for those trying to use Glyphicons will probably also work with bootstrap s Glyphicon-halflings : I was able to get glyphs working with doc.AddImageHtml by adding the following css only when building a pdf : .glyphicons font-family : GLYPHICONS important the font will need to be installed on the server and the server rebooted" ] }

The mentioned story GHS-945 https : jira.atlassian.com browse GHS-945 had been resolved in GreenHopper 5.10 http : www.atlassian.com en software greenhopper whats-new greenhopper-510 already - meanwhile GreenHopper 6.0 http : www.atlassian.com en software greenhopper whats-new greenhopper-60 officially delivers all mentioned major improvements regarding Kanban Scrum and especially custom agile board planning and process-management plus many others not mentioned or available before . Accordingly the interim term Rapid Board has been dropped as well see No longer Rapid by name but still rapid by nature https : confluence.atlassian.com display GH GreenHopper+6.0+Release+Notes GreenHopper6.0ReleaseNotes-NolongerRapidbyname E2 80 93butstillrapidbynature : .. . .. . In GreenHopper 6.0 the new board is no longer known as the Rapid Board we figure everyone knows by now that it is vastly faster than the Classic boards . The new board has been built from the ground up on newer technology that enables us to provide optimum performance making the most of your valuable time . Finally the GreenHopper team continues to deliver significant improvements in almost biweekly point releases with the last one addressing one of the few losses caused by the transition from the classic boards : release 6.0.2 https : confluence.atlassian.com display GH GreenHopper+6.0.2+Release+Notes features customizable card colors https : confluence.atlassian.com display GH GreenHopper+6.0.2+Release+Notes GreenHopper6.0.2ReleaseNotes-Customisablecardcolours again even more versatile than the classical variant insofar you can now base the coloring on issue type priority assignee or a custom JQL query even .

Initial Answer .. . .. . The version vs . sprint impedance mismatch in many areas of JIRA http : www.atlassian.com software jira overview and GreenHopper http : www.atlassian.com software greenhopper overview is a well known problem for agile teams using this toolchain . We implemented various attempts to remedy it one way or another mostly via version hierarchies of sorts i.e . product versions and sprint versions with parent-child relationships none of which turned out to be really productive . Accordingly the relatively dated story Add a separate field to allow tracking sprint and release information independent of one another GHS-945 https : jira.atlassian.com browse GHS-945 captures this topic . While it is unresolved as of today GreenHopper is currently undergoing a major restructuring to address this and related problems and while not quite finished yet the respective functionality available today addresses your use-case already eventually see the Atlassian Status as at February 28 2012 : .. . .. . Sprint as a separate custom field is now available in GreenHopper 5.9 however it is only used by the Scrum Rapid Board which can be enabled as a lab feature from the GreenHopper admin screens . .. . The Rapid Board use of this field frees up fixVersion field for normal use . The mentioned Rapid Board and the restructuring in general is further detailed in The Future of GreenHopper http : confluence.atlassian.com display GH The+Future+of+GreenHopper : .. . .. . The Rapid Board is a fresh start for GreenHopper . We are building it to take advantage of the latest in web technology and provide you the customer with an awesome experience for planning tracking and reporting on the progress of your agile projects and teams . The Rapid Board http : confluence.atlassian.com display GH Using+the+Rapid+Board and related functionality currently improves quickly indeed i.e . the GreenHopper team iterates fast and implements major improvements in currently monthly to biweekly point releases even . I m totally sold on this approach which basically builds the board on top of the versatile JQL functionality see Advanced Searching http : confluence.atlassian.com display JIRA Advanced+Searching enabling almost complete freedom to assemble the perfect board for your needs . On top of that it solved the version vs . sprint impedance mismatch for us insofar sprints are decoupled entities now and versions can be used as desired again yielding a useful version and release date based customer facing JIRA Roadmap http : confluence.atlassian.com display JIRA Browsing+a+Project 27s+Road+Map in turn . The transition to this new approach is a dedicated effort of course requiring some planning and time eventually also there are still some relevant shortcoming concerning the previously available functionality for example the currently unresolved story As a user I would like to configure the cards displayed in the rapid board GHS-3922 https : jira.atlassian.com browse GHS-3922 is important for us because we have been using Philippe Kruchten s innovative approach to backlog coloring see What Color is your Backlog http : www.infoq.com news 2010 05 what-color-backlog with great success and this is not possible for the Rapid Board yet . Finally GreenHopper 5.9 requires JIRA 5.0 which may or may not be a showstopper right now . Comment : Wow incredibly insightful answer . We upgraded to Jira 5.0.2 re-indexed created a number of new projects to track things in those respective projects deleted all of our sprint versions entered all of the real versions started using the rapid board way better as you said and now we have our roadmap .", "Question : I m getting started working with the JIRA REST API .

Could you help me tweak this call to show all sprints for a particular rapidview .. . .. . Thanks in advance Adithya .. . Answer : JIRA API will not load all results . It will give it to you in chunks of small results . If there are lots of records then JIRA will send you it in chunk of 50 with one flag named isLast which carries value either true or false . True means : There are no more records to be fetched .. . .. . False means : Yes there are more records to be fetched but that will be provided to you only if you want via more REST requests . So on the basis of this you have to run a loop with more API calls to fetch all the results from JIRA database .

Answer : Short answer is no . The Epic issue type and a few others are added to a base JIRA installation when you install the JIRA Agile extension plugin . None of the features Epic Links Epics filtering on backlogs Epic burndown charts etc will work with any other issue type . I d suggest you begin adapting your process to use the new issue type .

Is it possible to have such a task in Jira .. . Answer : Sounds like you re asking for a Task that exists outside of sprints so therefore the simple answer is to create a place that can hold these . Do not use Jira s Agile page and just create these as normal tickets bugs . That or these should be just added to the backlog if they re to be prioritized for later sprints .

However there is also a push by me for using JIRA+Greenhopper+Fisheye+Crucible . Has anyone out there done a feature by feature comparison of these two tools Using the ServiceNow demo it sounds like it s quite versatile but I believe it s being customized pretty heavily for our call-center by Service-Now themselves . One of the biggest things that I ve liked about JIRA is the extreme level of customization that we can do on our own and morph our processes as a result-of our retrospectives . I m not entirely confident that ServiceNow can provide that and I would definitely like to hear more . Some features that I m wondering about in ServiceNow that I can accomplish with JIRA+Greenhopper : .. . .. . Sprints across multiple-projects Scrum Products in ServiceNow Source Code Review integration like with Fisheye and Crucible .. . .. . Epics management spanning multiple-projects .. . .. . Release Management - JIRA Versions vs . ServiceNow Releases - some teams plan out future releases and others simply cut a build-tag based on what looks good on their release branch .

ITIL Comment : My organization brought in ServiceNow for IT ticket management a couple of years ago and caused a full scale revolt among users especially engineers who were used to JIRA and found ServiceNow s UI cluttered confusing and non-intuitive . I would advise seriously looking at JIRA for your IT Ops and call center management and definitely don t try using ServiceNow for anything related to software projects .

Comment : We brought in SN as an IT help desk system to handle access requests general IT requests like server problems or new machine allocation and equipment ordering . The end users were anyone in the company . I may have been a bit down on SN above - things have improved after customizing the UI - but as @JeremySmith says below SN isn t necessarily a good fit for the software development tasks that you listed in your question . .. . Answer : Another disclaimer - I m an employee too .. . .. . Jira is a fantastic Agile toolset and to be fair can offer a better point solution for SDLC than ServiceNow . To balance that out - what you can gain from using ServiceNow SDLC is access to the single system of record for IT . Because you are using the same system as your IT Operations teams you have a chance to model a process that tightly integrates Dev and Ops We could throw in the DevOps buzzword here If you want a process where you can take a new incident from a customer and easily track it to the release to the software version to the requirement to the test case you need ServiceNow . Equally if you want to drive operational responsibility for the success of software features to the developers that write the code you want that seamless interaction between processes .

I also know how to get the issues for a sprint directly from the agile API : https : example.com rest agile latest board 5 sprint 4 issue .. . .. . but I can t seem to link the board to the projectkey . I have found a similar topics on the atlassian site itself but they usually mention there is no REST endpoint to do what I want . Although I m sure it should be possible . The answers I find elsewhere I don t really understand filter on rapidId s or something similar so I really need a noob-explanation of what to do .", "Question : We user JIRA for bug tracking and release management and we have started using greenhopper for project-management inside of JIRA but one thing that it lacks is the idea of user stories versus tasks in those users stories . Does anyone recommend other task board like agile-project-management tools that fully support users stories and tasks as well as being fast and simple to user . I started looking at targetprocess so if anyone has feedback on that specifically it would be great as well . Comment : SO is dead set against recommendation questions . You may try asking again in SoftwareRecs http : softwarerecs.stackexchange.com . .. . Answer : My company have been using TargetProcess for a while and we are very pleased with the product . Whenever we have experienced problems or bugs we have reported it to them and the problem or bug is solved really fast . It s a great tool that worked well with SCRUM . I really recommend it ." ] }

GWT compiles Javacode to Javascript . This has to be done everytime when you are redeploying . Since Vaadin has to be understood as a server-centric framework eliminating your flexibility on writing Code that is executed on Clientside and moving everything to the server which sounds worse than it actually is the GWT Compiler only runs once a time . For example this happens when you are importing a plugin from the vaadin website . But it can t be that easy right If it only would compile the code of the plugins to javascript this could have done before . So my question is : .. . .. . When does VAADIN use the GWT Compiler and what does it do at that point other than compiling to js .. . Answer : Basically you have it right and mostly answered the question yourself . In Vaadin the user-interface components consist of two parts : .. . .. . 1 . Server-side component compiled using JDK .. . 2 . Client-side widget compiled using GWT .. . .. . These parts communicate with each other over HTTP and automatically synchronize their state as needed . Server-side part maintains the state of the user-interface component and the client-side widget renders that state . Application developers typically only use the server-side components to build the application and they don t really have to care about how the client-side works . In general new components to Vaadin can be developed in two ways : .. . .. . 1 . Composing existing components .. . 2 . Creating a new widgets with GWT JavaScript + other client-side tech .. . .. . The first method here uses the existing classes and don t need recompilation of the widgets with GWT . Only the application code is compiled with JDK compiler . However in the second scenario the client-side classes change and need recompilation . This is when the GWT compiler is needed . Due to the rather monolithic nature of the GWT compiled JavaScript regardless of new code splitting features of GWT the namespace is global Vaadin uses the concept of widget set . That is a GWT module that contains all the widgets needed in the application . That means that adding new client-side widgets to an application a GWT recompilation is needed . It is also a good practice to recompile widget set when removing widgets to optimize the widget set size . GWT compilation step itself is nothing special . However Vaadin itself contains lot of additions helpers and workaround to GWT classes that are applied and used by the widgets . All this is quite visible when using Vaadin add-ons see http : vaadin.com directory . Even add-on are simply jar-files if they contain a new client-side widget code widget set compilation using GWT is needed when they are added to a project .", "Question : Has anyone tried implementing a web application with Clojure using Compojure and Vaadin I had seen an article on using Clojure with JWT for creating web apps .

And Clojure gives the advantage that you can use any Java Based Framework so what thoughts on the Clojure + Vaadin based web application Comment : I used JWT as well as Vaadin . very nice but much more community support and documentation for Vaadin .. .

And Clojure gives the advantage that you can use any Java Based Framework so what thoughts on the Clojure + Vaadin based web application Comment : I used JWT as well as Vaadin . very nice but much more community support and documentation for Vaadin .. . Answer : Yes created youcaneatat.com entirely in Clojure and vaadin . The advantages of Clojure using Clojure are that it is a Lisp and the advantages of using Vaadin are that you get to code everything using only serverside programming techniques so you do not need to think about Javascript callbacks or anything like that .

Can these technologies be integrated Is there a module or must some other approach be used Comment : Why is this question closed I too would like to know the answer to how gwt and play2 can be used together . Has anyone used them to any degree Outcomes pros cons Thanks Comment : It would be better if you attach the Play Framework 2 links you are using . I almost got it confused with PlayN framework .. . Answer : You can t use Vaadin with play2 . Vaadin is basically a Java EE servlet that must live in a Java EE container such as Tomcat . Play is not based on Java EE it uses its own server . As for GWT all server-side code needs a Java EE container . But if you just want the client-side then it s totally possible as it is with any web framework . Just create json web-services and remove server dependancies . For an example in php : http : gwtquickstart.blogspot.fr 2009 11 call-php-script-from-gwt.html Comment : this stuff is simply not true . there have been plugins for running gwt with play for 1.x and there are some for 2.x as well . the only thing gwt vaadin needs from the servlet architecture is a way to communicate with the client .

As I said it s complicated to develop the web application alone if you have to learn Javascript and browser compatibility at the same time.. . JQuery is fully portable that should save you some time . Good luck . .. . Answer : I d say go for Vaadin . It s Swing like development without the HTML JavaScript CSS and any other helpfull libraries . Even though this is a polyglot development time pick simplicity and productivity over flexibility . You ll thank yourself in the long run . Comment : Yes it performs validation on the server-side . It causes some performance issues but I wouldn t be worried about that . Java is one of the fastest languages out there . You should concern yourself about productivity not about performance . There is a link can t find it right now on the Vaadin home page or blog about their performance . Needless to say it s fast . Comment : Vaadin code executes in the server-side If yes would it cause performance issues Btw what do you mean by polyglot development time question answered above Comment : Here is the link about the performance - vaadin.com blog - blogs vaadin-scalability-study-quicktickets https : vaadin.com blog - blogs vaadin-scalability-study-quicktickets . Vaadin is based on the GWT framework . It s sort of a server-client communication without the need to code in 15 languages Java compiles to Javascript . That s what I meant by polyglot - programming polyglotism en.wikipedia.org wiki Polyglotism http : en.wikipedia.org wiki Polyglotism . And Vaadin uses that sort of communication it s built on top of GWT but uses the validation on the server . Comment : what are the cons in using vaardin can i use it to include google-maps or similar widgets in my apps Comment : The cons are well the cons of any component based UI . And as you mentioned performance . To use google-maps as a part of Vaadin no you should create your own component . You can create it using GWT vaadin.com book - page gwt.html https : vaadin.com book - page gwt.html . That s the drawback - you have a limited number of components . The components are rich simple to use but if you want something custom - you have to create it . There are user components as well - you can check it out . To sum up - the cons are performance and flexibility .", "Question : Can anyone suggest whether GWT or Vaadin are a better choice to design an application Also : what are the differences in coding-style .. . Answer : Differences between Vaadin and GWT : .. . .. . A Vaadin includes a server-side development model that : .. . .. . Cuts number of code lines to half by reducing layers one has to implement for user-interface . Allows you to use any JVM based language for user-interface - Scala Groovy .. . Increases security by keeping user-interface logic in the server .. . Allows synchronous calls to any backend API from the web server .. . Allows use of any standard Java libraries and tools for UI layer- in server-side architecture applications .. . Does not need Java to JavaScript compilation step that often takes time or makes tooling complicated in GWT projects - instead you have the Vaadin client engine .. . Provides server-push out of the box with no extra code needed .. . .. . B Vaadin provides a large set of high level user-interface components . For GWT one would need to use commercial Sencha GXT for comparable component set . C Vaadin includes SASS based Valo theme engine that makes it easy to build good looking custom themes from your application . Valo is the latest theming for Vaadin . D Data binding : Vaadin has incorporated the ability to associate any widget directly to a data source such as database file or anything else in the server-side . This enables to define default behavior of the widgets to act on data sources . Vaadin vs GWT https : www.quora.com What-are-the-benefits-of-using-Vaadin-over-plain-GWT", "Question : I just tried to play with Vaadin Framework http : vaadin.com home and it seems to me very easy to use . Plus what I like about his framework is that it is built on top of GWT . What do you think should I continue using this framework or it s better to stick with GWT . .. . Answer : The usual talk about Vaadin concerns the widget set and worries about round trip communication between client and server . But in my opinion this overlooks the most significant perhaps revolutionary aspect of Vaadin : it completely eliminates the task of designing and implementing the client-server communication that is usually required for AJAX applications the A and X in AJAX . With Vaadin you can completely forget DTO s data-transfer objects protocol-based security problems Hibernate lazy-loading exceptions etc . You are in some sense just writing a regular old Java Swing desktop application only you are using a different UI toolkit from Swing . Comment : Hibernate lazy-loading exceptions are common with Vaadin if you don t handle them correctly . Usually you will use a session-per-request pattern which means that your entities will be deattached from the hbn session at the end of the http-request . If you try to lazy load anything outside the same http-request a lazy-loading exception will be thrown - unless you re-attach the entity to the active session . Comment : You re right about that i.e . the case of lazy-loading problems when an object is used across multiple requests . With Vaadin you do need to understand where your objects are going to go between requests including the possibility of serialization . Comment : @Archie : I think that you re slightly oversimplifying the issues encountered when using ORM sessions with Vaadin or any stateful web framework actually . We found that struck the right balance when binding the life cycle of our entity managers in JPA alright to that of the layouts themselves .", "Question : I am evaluating possibilities to create mobile hybrid Apps with GWT and Apache Cordova PhoneGap . I already build a small prototype with mgwt and liked it but I would like to research a few other possibilities before starting the project . Therefore I took a look at Vaadin and its AddOn Touchkit . I have the following questions : .. . .. . 1 . Is it possible to use the Vaadin Touchkit Addon in a Client-Side Application which does not need a permanent server connection In the mobile chapter https : vaadin.com book vaadin7 - page mobile.html of the documentation an example is shown that is a Server-Side Application as far as I understand it and therefore would need a server connection for each UI event . Please correct me if I m wrong I have no experience with Vaadin . 2 . Is there any difference between a normal GWT App and a Client-Side Vaadin App 3 . Does it has any advantages to use Vaadin Touchkit instead of mgwt 4 . In general is Vaadin Touchkit comparable to mgwt and if yes which are the main differences .. . Answer : 1 . You can build a Vaadin TouchKit applications that work offline . The Parking Demo shows this : http : demo.vaadin.com parking Source code here : https : github.com vaadin parking-demo By default default the application is online but for the data-entry the app uses offline client-side-only approach . 2 . If you are building a client-side Vaadin app you would still use the TouchKit widgets . Until version 3 TouchKit widgets have followed the iOS native widgets but v4 introduces new styles that are more device agnostic and better suitable also for Android devices . 3 . The most prominent difference and advantage if you wish of Vaadin TouchKit is however the default server-side programming approach . It is very quick to build mobile optimized web-applications - especially if you already have an existing Java web application and business logic in-place . For client-side apps the visible difference is the look-and-feel of the Touchkit and mgwt widgets . 4 . Generally this is also where it boils down to : If you are quite ok to have parts of the application running online data on server and need the offline-mode is only needed for some parts of application Vaadin TouchKit is very quick and efficient way to build decent looking apps . On the other hand mgwt gives you direct start on the client-side-only applications and is maybe better optimized for that . You had already found out that both suffer from the sandboxing of HTML5 applications . While camera and location APIs are available a solution like phonegap is still needed to really integrate with the device and match native applications .", "Question : I just tried to play with Vaadin Framework http : vaadin.com home and it seems to me very easy to use . Plus what I like about his framework is that it is built on top of GWT . What do you think should I continue using this framework or it s better to stick with GWT . .. . Answer : Hey . As a disclaimer I work for the company developing Vaadin . Vaadin uses GWT in a way that it has a set of components precompiled in GWT . You can of course additionally make your own components if you so want to . However the set of components is quite complete and can often be customized for your own need . This means that you don t have to recompile your code from Java to JavaScript every time you change your application . You just combine the already available components together . The framework is server driven so all logic is handled on the server-side . The components has two parts client and server file . The client-side is just a dummy view for the component . Once you interact with it it sends a message to the server that this or that was pressed written etc . The server then decides what should be done . This is for increased security because you can t hack the logic as only a small API meant for sending requests is available in the javascript . This may be in some cases a little trade-off with speed of the application but I don t think it is a so bad . Worst speed bumps are usually db query round-trips and such which doesn t have anything to do with the choice of the UI framework . Sluggishness of the demos as suggested can be because you re far from the server or there is a high user hit at the moment . Try it in an own environment close the the final application of your application to see how well it performs . There are some ready application that you can just deploy to test it out . I guess the choice boils down to what you are trying to do . Vaadin is good for web-applications as you can build a normal Java application and do the dynamic web UI for it easily . If your doing something more of a traditional web site where users only views the page - more than actively interacts with it then Vaadin is not the best way to go . Go with some other free frameworks like rails or a php framework etc . I think that you re more doing an application as you re suggesting that you are using GWT now so Vaadin should be good . Ask more questions here on the Vaadin forums or at the irc channel vaadin @freenode and maybe someone can give you more reason to why or why not use Vaadin . Comment : Hi Jens I was beginner to vaadin and we are planning integrate with our app with vaadin . we planned to control all UI and components based on the xml-configuration . Can you suggest better way to implement vaadin flexibly.Your answer would help me a lot.Thanks in advance Comment : I don t work for Vaadin and will concur . Vaadin is beautiful . By far the best framework I ve used in the last few years . I am infinitely more productive . Please tell your coworkers that they have produced an awe inspiring product and I am highly appreciative . Comment : I m a fan of Vaadin but developers should know they have a rather expensive add-on scheme . We have a few desktop browser applications that are pretty nice but for our mobile we couldn t justify the 490 price tag per developer . But that s still cheaper than the almost 5K Sencha charges . Comment : Vaadin is somewhat sluggish and the low price is as @cbmeeks mentioned misleading since many of the features that you might want to have are paid and at a very steep price so you either have to write your own stuff look for alternatives usually there are such though since they are not supported by the company behind Vaadin as a company you might be put in a tight position or cough up the money . Things get worse if you go mobile . I would probably stick to HTML5+JS in such scenarios . So yeah it s a nice framework but as all out there it has its drawbacks . Comment : hello jens : I have a vaadin based web application its making 5000 network requets in single page loading. . what could be reason for that any idea", "Question : I m working to learn some good frameworks o set of frameworks languages for to build some RIA java based not exclusively business-oriented ones . I m at my start so excuse me for so general question . Actually I ve spent some time on GWT and i like that philosophy . Problem is Java 8 I m working with Java 8 and there is an incompatibility with GWT I know is only matter of time to be resolved but in the meantime i m working around . Now I ve understood that GWT is the best for to build client-side RIAs but lack somewhere in the server-side aspect and it probably need to be reinforced in some way . But what s means reinforcing what can be the good partner server-side for GWT I ve gived a look at Vaadin but i don t like so much that philosophy : the Gwt idea to spare the elaboration load from server and client is winning in my opinion while in Vaadin if i don t understand wrong the elaboration is almost only server-side . Now the question is : what is the best 2014 practice road Only GWT GWT + server-side add-on s and what addons Vaadin Or something different Comment : I am using GWT for many years and I see no limitations either on the client-side or on the server-side . In my opinion all this talk about limitations is an attempt by some vendors to differentiate their products . That being said SO is not a discussion forum - so this question does not really fit in here . .. . Answer : I think you must consider what you wish to do . If you wish to stay with java then a GWT based solution is great . GWT gives you many features and not much hassle with javascript . If you need only client-side application with not much server interaction this is a good choice . Of course you then need a server-part of your project . Vaadin commes in when you anyway have a server-side solution with much businesslogic datalayers background jobs etc . etc . Or when you don t wish to write GWT stuff yourself . You still can if needed .. . .. . Your business logic is running on server-side the communication with the webbrowser is secured agains usual web exploits attacks . You would have to implement them yourself when using a own or xml json based protocol .. . .. . Vaadin integrates client+serverside without the need to hassle with GTW or Javascript . So : .. . .. . For projects with no or not much server-side code Business layer go for GWT For all else go Vaadin", "Question : Can anyone suggest whether GWT or Vaadin are a better choice to design an application Also : what are the differences in coding-style .. . Answer : A few more points : .. . .. . A fundamental difference is that in GWT you have to separate your application into Client and Server code no such distinction in Vaadin . This will affect the architecture of your application . In GWT client code you must code in Java and have a limited subset of language features available that the GWT compiler can translate into Javascript . In Vaadin you can code in any JVM language since everything runs in the server I m using Vaadin with Scala . This may or may not be relevant to you . GWT compilation is VERY slow although in development mode you have the emulator . This makes production environment updates painful a GWT application I developed has grown pretty big and currently takes around 15 minutes to compile . It s very simple to extend GWT with 3rd party widgets or roll your own . Creating new Vaadin widgets is more complex .", "Question : How to check in Vaadin 7 if scrollbar is visible or not for a certain component for example for Panel Comment : I don t think it is possible out-of-the-box with Vaadin but you could do some JavaScript see here https : vaadin.com docs - part framework advanced advanced-javascript.html and here http : stackoverflow.com a 4814526 1063673 .

Right now I have no any solutions other than test scrollbar visibility .. . Answer : Any implementation of AbstractClientConnector can be extended with AbstractExtension : https : vaadin.com api com vaadin server AbstractExtension.html .. . .. . An extension is a possible way to extend the functionality of your component : https : vaadin.com docs - part framework gwt gwt-extension.html .. . .. . Adding features to existing components by extending them by inheritance creates a problem when you want to combine such features . For example one add-on could add spell-check to a TextField while another could add client-side validation . Combining such add-on features would be difficult if not impossible . You might also want to add a feature to several or even to all components but extending all of them by inheritance is not really an option . Vaadin includes a component plug-in mechanism for these purposes . Such plug-ins are simply called extensions .

Plus what I like about his framework is that it is built on top of GWT . What do you think should I continue using this framework or it s better to stick with GWT . .. . Answer : Well I d like to comment something . After almost 1.5 year developing a not so huge GWT application using all the best-practices I learned from the last Google I O like MVP EventBus CommandPattern etc . I say this from the bottom of my heart : after spending days trying to get things work out the way my team and client wanted both technically and visually even after the release of UiBinder Vaadin came to me like a light in the end of the tunnel . After writing almost a thousand boilerplate actions for command-pattern another thousand presenters and views and another thousand event handlers etc. . Not having to deal with almost 75 of these classes and still maintaining a good pattern approach appfoundation add-on a little network overhead is acceptable . With Vaadin out-of-the-box you get good widgets paging data-binding flawless layouting . All of this for what Some more memory consumption in the server-side . I think I can say this is acceptable because I m not building the next Facebook or something . I still can handle thousands of simultaneous users per medium server and yet maintaining low-latency round-trips . With Vaadin I can build a nice app with almost a half of lines-of-code and still the application seems more complete . : - .. . .. . UPDATE February 23 2011 : I can t stress out how one should be aware of each framework s limitations . Vaadin is no different . One should be aware that Vaadin abstracts away any form of html or javascript . Also the resulting HTML is veeeery heavy and you should take care of history state changes yourself . So be aware of those overheads when you build your project . Marcos Alcantara Comment : I can answer that for you since I work for Vaadin Ltd : no he doesn t .

Answer : In GWT application logic is normally run on client-side . It only calls server when it needs to read save some data . In Vaadin application logic is on server-side . Client side must normally call server after every user interaction . GWT advantage : .. . App logic replies to user interaction is faster as it is run locally in the browser . It s also relatively insensitive to bad network conditions . Network is used only when needed to read save new data which saves net traffic important for high traffic sites . In this regard Vaadin is slower and introduces a lag in UI interaction which is annoying to user . If network is bad this will show in UI responsiveness . Vaadin advantage : .. . App logic is run on the server so it can not be inspected by the user . Arguably Vaadin claims that makes it more secure .", "Question : Can anyone suggest whether GWT or Vaadin are a better choice to design an application Also : what are the differences in coding-style .. . Answer : I belive Vaadin is a much more advanced framework than GWT BUT When it comes to optimise performance on the client-side there is nothing much you can do unless you build your own components and that s where the beauty of Vaadin stops In a project i m working right now 90 of the staff I ve done worked as a charm And then I had to use an event timeline next to a couple of tables .

Some relevant documentation could be helpful too . Comment : My two cents : Vaadin uses a lot of memory on the server-side like JSF so if you have a lot of clients it may be hard to scale.. . .. . Answer : Vaadin .. . .. . Vaadin in an amazingly good tool for building interactive desktop-style web apps developed in pure Java and delivered via regular web browsers . Benefits .. . .. . Vaadin http : www.vaadin.com 6 7 apps run entirely on the server-side . The JavaScript library automatically installed by Vaadin into the user s browser window simply : .. . .. . Draws on-screen whatever the server-side app tells it to . Feeds user actions clicking typing and so on back to the server for the app to consider and respond . So there is no logical validation on the client-side or html5-validation at least not from the Vaadin app developer s point of view . The Vaadin framework may do so under-the-covers in its internal implementation but that is none of my concern as a Vaadin app developer . That s the core benefit of Vaadin : I don t care how Vaadin gets my forms onto the user s screen . As a Vaadin app developer I am not writing any JavaScript HTML DOM CSS or AJAX . Just pure Java . The style is similar to Swing http : en.wikipedia.org wiki Swing 28Java 29 : Instantiate a layout https : vaadin.com book - page layout.html a form add labels https : vaadin.com book - page components.label.html add buttons https : vaadin.com book - page components.button.html add fields https : vaadin.com book - page components.textfield.html add other widgets https : vaadin.com demo . Attach validators https : vaadin.com book - page components.form.html components.form.validation as needed . Nest additional layouts for complicated forms . All of that executes in memory on the server-side all in pure Java . Finally tell the layout to show itself . Poof like magic Vaadin tells the browser to display a likeness of that form . If you want to develop desktop-style business-style apps that happen to be deployed through a web browser Vaadin is a wonderful tool . Trade-Offs .. . .. . Trade-offs include : .. . .. . Lots of memory and CPU usage on the server-side . Giving up control over the HTML CSS JavaScript . Scaling .. . .. . Your web app lives on the server not the client . All your business logic the users entered data the internal representation of all the users s forms such as row items in a table all this lives on the server . Multiply that by number of users . This means a Vaadin app can demand much memory and CPU usage . That may limit scaling up . But given 64-bit Java multiple gigs of memory and multiple cores on even the lowliest of machines such as a Mac mini http : www.apple.com macmini server scaling-up is likely an issue only for the largest busiest of apps . And even in those rarer of large busy app there may be ways to handle scaling in Vaadin . All of the app lives in a Servlet Session . Some web infrastructure allows such session-state to be moved between servers or even persisted out to storage to be picked up by other servers . Or your app may scale well . Simulations with 11 000 simultaneous clients have been done . See : .. . .. .

Scaling with Vaadin and WildFly Webinar https : youtu.be kCOd9l4WGNY with Arun Gupta video presentation YouTube .. . .. . Control Over HTML CSS JavaScript .. . .. . If your team is more comfortable or experienced with conventional web app architectures then Vaadin may not be for you . In Vaadin you write your app entirely in pure Java and Vaadin translates that to HTML CSS and JavaScript automagically . You can tweak the CSS a bit . And even without touching CSS Vaadin s themes Valo https : vaadin.com valo Reindeer http : demo.vaadin.com ReindeerTheme give you much control over colors sizes and fonts if you wish to override the defaults . But know that Vaadin is in the driver s seat in generating the HTML CSS you are just passenger who is allowed a small bit of backseat-driving . If your goal is something other than developing desktop-style apps if you want to take full control of the HTML CSS then Vaadin may not be for you . .. . .. . Update .. . .. .

I tried to setLocale method on vaadin component surrounding this widget but it didn t help . Problem is that where vaadin locale is server-side method it can change the data sent to client .

When in vaadin widget it does no care at all about browser locale request language tag or GET parameter . .. . Answer : One of the problem was locale name mismatch . Where vaadin application was able to be translated ony for language-tag locale . e.g . pl polish gwt widget needed locale with country code e.g . pl PL polish Poland . The actual solution was to force gwt to search for locale in meta tag only and create this tag .. . .. . on server-side respecting application language and before any gwt javascripts are attached .

From what I can tell it seems to be a tool designed to solve very specific problems related to upwards of 10+ billion rows aggregating caching and querying data from other sources HBase Hadoop Hive . Am I correct in this assumption Comment : Look at : ebaytechblog.com 2014 10 20 http : www.ebaytechblog.com 2014 10 20 announcing-kylin-extreme-olap-engine-for-big-data Comment : That doesn t really give generic use cases rather explains how Ebay used it as ebay developed the tool in the first place and architecture of the product . .. . Answer : Apache Kylin s use-case is interactive big data-analysis on Hadoop . It lets you query big Hive tables at sub-second latency in 3 simple steps . 1 . Identify a set of Hive tables in star-schema . 2 . Build a cube from the Hive tables in an offline batch process . 3 . Query the Hive tables using SQL and get results in sub-seconds via Rest API ODBC or JDBC . The use-case is pretty general that it can fast query any Hive tables as long as you can define star-schema and model cubes from the tables . Check out Kylin terminologies http : kylin.apache.org docs gettingstarted terminology.html if you are not sure what is star-schema and what is cube . Kylin provides ANSI SQL interface so you can query the Hive tables pretty much the same way you used to . One limitation however is Kylin provides only aggregated results or in other word SQL should contain a group-by clause to yield correct result . This is usually fine because big data-analysis focus more on the aggregated results rather than individual records . Comment : Would the following use-case be valid a Design a-star schema using HiveQL b Load data into Hadoop using a Hive connector c Kylin would handle mapping the Hive schema to a cube schema and executing the Map Reduce through HiveQL d Output the results of the query to HBase e Use Kylin for executing SQL statements via Calcite to HBase and returning the results as JSON . Comment : Very close Just note step c is manual the mapping from Hive schema to cube schema is manual Kylin provides a GUI for you to do it . Also step d the output is not specific to any query but a general index of the Hive data we call the index cube .", "Question : Sorry I just start to lean kylin .. . .. . When I execute the sql select from kylin sales where price 2 in default sample cube of kylin it failed with the message .. . .. . anybody knows the reason Thanks .. . Answer : Kylin is a MOLAP https : www.youtube.com watch v IhFkNmVmwn4 multidimensional online analytical processing engine . It divides columns into dimensions and measures expects queries to filter by dimensions and return aggregated measures . Your query select from kylin sales where price 2 does not work because price is not a dimension thus is not suitable for filtering . Also the query does not select any aggregated measures . A simple MOLAP query is like select week beg dt sum price from kylin sales where meta categ name Collectibles group-by week beg dt .. . .. . Kylin also supports a special type of RAW measure that allows filter such as price 2 but that s not demonstrated by the sample cube .

And when certain node missing the Hive jars or even in different location you get the ClassNotFoundException on HCatInputFormat . Btw you should be able to get a clear error message from Yarn job console . This is a met issue . Deploying Hive to all cluster nodes can surely fix the problem like you have tried . Or another cleaner workaround is manually configure Kylin to submit Hive jars as additional job dependencies . See https : issues.apache.org jira browse KYLIN-1021 .. . .. . Finally there s also a open JIRA suggests that Kylin should submit Hive jars by default . See https : issues.apache.org jira browse KYLIN-1082 Comment : hive is a client .

Answer : The issue you encountered is that cut command on mac-osx does not support --output-delimiter option . I encountered the same error while installing kylin-1.5.1 . The easy to solve it is to use the gnu binaries in your shell instead of osx binaries . Use brew http : brew.sh for installing coreutils I changed all the commonly used shell utils to their gnu versions .. . Use the below command for that .

I have same configurations on all nodes . .. . Answer : What Li Yang suggested is correct . Here is my sequence of experiments . Kylin ships a jar file specified by kylin.job.jar property in kylin.properties . So first I made a fat jar file with missing dependency set path of this file in kylin.job.jar and ran the job again . The missing class was now shipped with MR job . The newly added dependencies had some dependencies which were not available on all nodes hence the job failed again . In next iteration I added those missing dependencies and tried again . Same result : newly added dependencies had some more dependencies which were not available on all nodes . Finally I extracted all classes available in HIVE HOME lib hive- .jar and created a new jar . This time it worked . Size of the jar file was over 20MB . Since these jar files are used every time I run a cube job I coppied all these jar files to all the nodes under HADOOP HOME share hadoop common hive-metastore-0.14.0.jar .

Answer : How to make integration between Apache Kylin and Facebook Presto and so Apache Kylin can read from Facebook Presto instead of reading from Hive", "Question : Apache Kylin looks like a great tool that will fill in the needs of a lot data scientists . It s also a very complex system . We are developing an in-house solution with exactly the same goal in mind multidimensional OLAP cube with low query latency . Among the many issues the one I m concerned of the most right now is about fault tolerance . With large volumes of incoming transactional data the cube must be incrementally updated and some of the cuboids are updated over long period of time such as those with time dimension value at the scale of year . Over such long period some piece of the complex system is guaranteed to fail and how does the system ensure all the raw transactional records are aggregated into the cuboids exactly once no more no less Even each of the pieces has its own fault tolerance mechanism it doesn t mean they will play together automatically . For simplicity we can assume all the input data are saved in HDFS by another process and can be played back in any way you want to recover from any interruption voluntary or forced . What are Kylin s fault tolerance considerations or is it not really an issue .. . Answer : There are data faults and system faults . Data fault tolerance : Kylin partitions cube into segments and allows rebuild an individual segment without impacting the whole cube . For example assume a new daily segment is built on daily basis and get merged into weekly segment on weekend weekly segments merge into monthly segment and so on . When there is data error or whatever change within a week you need to rebuild only one day s segment . Data changes further back will require rebuild a weekly or monthly segment . The segment strategy is fully customizable so you can balance the data error tolerance and query-performance . More segments means more tolerable to data changes but also more scans to execute for each query . Kylin provides RESTful API an external scheduling system can invoke the API to trigger segment build and merge . A cube is still online and can serve queries when some of its segments is under rebuild . System fault tolerance : Kylin relies on Hadoop and HBase for most system redundancy and fault tolerance . In addition to that every build step in Kylin is idempotent . Meaning you can safely retry a failed step without any side effect . This ensures the final correctness no matter how many fails and retries the build-process has been through .

Failed to initialize XMSFactoryFactory Comment : See my update to answer .", "Question : We have .NET application which reads from various queues using the XMS API . For this particular application we read from 3 queues and every so often receive the error with reason code 2003 on 2 of the 3 queues . All 3 of the queues are setup to have persistent messages . From everything I have researched it appears that a long running transaction being rolled back causing this error . The reason for the long running transaction being rolled back appears to be from exhausted log space . When the transaction gets rolled back it puts the messages we have previously read onto the queue so we end up reading duplicates . In the API when we create our Session to read from the queues we specify false for the transacted parameter . Therefore we never call Commit on the session . We also use the auto-acknowledge mode on the session . This leads me to believe that we don t have any sort of unit of work sepcified explicitly but could there be an implicit transaction of some sort The tricky part is that we are able to read fine on 1 of the 3 queues without ever receiving the error .

Creating the consumer : .. . .. . Reading from the queue : Comment : Can you please post sample code that shows the problem Comment : I edited the question with some code on how we connect and receive from the queue . .. . Answer : XMS .NET reads persistent messages under a local a transaction as the Session is created as non-transacted and auto acknowledge . This is to avoid any message loss during delivery of a messages to an application . Hence XMS .NET internally calls a Commit to tell the queue manager to remove a message from a queue . Your code is very simple I don t see a problem . Are there any malformed messages in any of the queues Messages having headers that XMS does not understand would be backed out to backout BOQUEUE queue after the backout threshold BOTHRESH is reached . Have you defined a backout queue or dead letter queue for the queues from which your reading messages Are messages piling up in backout queue Finally I would suggest to raise a PMR with IBM to resolve the issue .", "Question : I m using the IBM websphere XMS API to connect and send messages to the mainframe .

Consumer : Comment : Hi Shashi I m not sure if you have seen this question http : stackoverflow.com questions 35223841 messageproducer-send-is-too-slow-for-a-particular-topic but since you re the only reachable person with authentic information I d request you to see the question .", "Question : I m using XMS 7.5 client to access the IBM MQ and wanted to know one thing about MessageListener . When there are multiple messages are present on the queue .. . .. . will the associated MessageListener method i.e ProcessNewMessage in the below code called concurrently OR .. . The messages will be dispatched to the MessageListener i.e ProcessNewMessage in the below code method only at a time The code is something like below : .. . Answer : Messages are delivered one at a time to consumer it does not matter whether the consumer is calling receive or has setup a message listener to receive messages . In case of a message listener MQ will wait for the OnMessage in your case ProcessNewMessage method to return before delivering the next suitable message . Comment : Is there any timeouts are set internally within which OnMessage handling method has to return Comment : No no timeout set .", "Question : I ve narrowed down the area of the problem I m facing and it turned out that MessageProducer.send is too slow when it is created for a particular topic replyfeserver : .. . .. . Here the call to send blocks for up to 55-65 seconds occasionally almost every after 4-5 calls and up to 5-15 seconds in general . However if I use some other topic say feserver.action.status . Now the call to send returns immediately within a fraction of second . I ve tried send with several other topics and all of them work fast enough . What could be the possible issues with this particular topic replyfeserver What are the things I should look at in order to diagnose the issue with it I was using this topic for last 2 months . I m using XMS C++ API and please assume that context object is an abstraction which creates session destination consumer producer and so on . I d also like to know if there is any difference between these two approaches : .. . .. . vs .. . .. . I tried with both it doesn t make any difference at least I didn t notice it . Comment : I agree with Rogers comment Comment : Best way farward is to open a PMR . Comment : @Shashi : I didn t understand that . What is PMR How to open it Comment : I meant raise support ticket with IBM to analyse delay Comment : @Shashi : Where should I do that Is it something online .. . Answer : There shouldn t be any difference . Personally I like to have my topics in a hierarchy . i.e . A.B.C .. . .. . I would run an MQ trace then open a PMR with IBM and give them the trace and say please explain the delay .", "Question : We are using IBM MQ as a messaging layer with multi instance setup . The .NET application using XMS client ver 7.5 will read off messages from the multiple Queues . Since the volume of the message is high I have created around 5 connection per queue to read the messages . And there are 4 such queues . So in the application at any point of time there are 20 connections and 20 session opened . With this setup I am facing two issues : .. . .. . Often I get the two XMS exceptions while opening the connections.One is MQRC HOST NOT AVAILABLE 2538 X 9EA The attempt to allocate a conversation to the remote system failed . and the other is MQRC CONNECTION BROKEN Connection to queue manager lost . While closing the application it is taking lot more time to close of all the sessions and connections because they are too many of them . So I was thinking to reduce the number of connection . By just creating one connection per queue and open 5 session per queue . In this way the number of connections will be reduced to 4 from 20 . So both the above said issues will be solved I think yet to try .. . .. . So wanted someone in the know to share their experience on what is the best practice of handing the above scenario . Will there be any delay in delivering the messages if we open multiple sessions per connection compared to single session per connection The code I m using is below : Comment : You ve accepted Shashi s answer so does that mean you ve solved the problem If so could you leave a comment or update your question to indicate what the solution was for the benefit of future Stack Overflow users whose search turns up this Q A Thanks .. . Answer : Not much of action happens on Connection . It s used for creating temporary destinations . Session is where all the actions happens . So just one connection is sufficient . MQRC HOST NOT AVAILABLE and MQRC CONNECTION BROKEN may not be due to the number of connections sessions you are creating because a queue manager can support a large number connections . Your application is using a transacted session and message listener . How are you committing transaction . Can you show us the code for that Are you calling commit for every message received Comment : Yes Shashi . I m committing on each message . If not how can we commit the session if queueSettings.UseTransactedSession disposed true sessionWMQ.Commit", "Question : I am trying to send Text messages using IBM XMS for .NET . After sending around 254 messages I get following error : .. . .. . There isn t much on google about it . I found one related post at WSMQ Queue Limit http : stackoverflow.com questions 1539826 wsmq-queue-limit .. . .. . The post suggest that there is some sort of limit in max queues . The links in the post don t seem to work . How do I overcome this error .. . Answer : MQ has a command mqrc which returns the text for any reason code or message code . The 2017 means MQRC HANDLE NOT AVAILABLE . A better explanation can be had by going to the Knowledge Center http : www-01.ibm.com support knowledgecenter SSFKSJ 8.0.0 and searching on 2017 . This returns several pages of API calls which can return 2017 along with the page for the reason code itself : .. . .. . 2017 07E1 RC2017 : MQRC HANDLE NOT AVAILABLE http : www-01.ibm.com support knowledgecenter SSFKSJ 8.0.0 com.ibm.mq.tro.doc q040900 .htm lang en . That page provides the following description of the problem : .. . .. . Explanation .. . An MQOPEN MQPUT1 or MQSUB call was issued but the maximum number of open handles allowed for the current task has already been reached . Be aware that when a distribution list is specified on the MQOPEN or MQPUT1 call each queue in the distribution list uses one handle . We know from the documentation and can confirm from MQ Explorer s QMgr Extended Properties panel that by default the maximum handles any process will be allowed to have is 256 . Screen shot of MQ Explorer QMgr Extended Properties panel http : i.stack.imgur.com Icpwd.jpg .. . .. . Based on all this and that your program is dying after 254 messages the conclusion is that it is grabbing a fresh handle for every message being PUT and not ever releasing them . Generally this occurs when there is a loop that should contain only the PUT and COMMIT but instead also contains the OPEN . I would suggest carefully reviewing your code possibly also updating your question to post the code here . I would also suggest studying the MQ .Net sample programs or using one of them as the basis for your own code .", "Question : null .. .

And in my case it mostly waste of time since my models hanging infrequently . Is there way to turn off this .. . Answer : This is not possible without modifying the source code of Django which is not recommended . The only validation Django does on start-up is to check if the syntax of your model code is okay or not . It should not take more than 2-3 seconds . So there are few other initialization are being done during startup which are also taking time . During development you do not need to restart the server every time you modify the code- especially if you are not touching the definition of the models at all . The Django dev server automatically reloads itself if it detects any change in your code . So leave it running while you develop and hopefully your experience will improve . Comment : Actually if one follows your advice it is even MORE annoying with the model-validation In any case one can just uncomment the line self.validate display num errors True in django core management commands runserver.py Comment : Your comment actually doesn t seem to turn off the delay with validation only the message . Is that right or am I mistaken Comment : Okay I am mistaken . However the printout of validating models is misleading in terms of the delay . The validation is not the source of the delay as commenting it out does not speed the servers responsiveness . It must be elsewhere . Comment : Mistaken again It is the validation . However commenting it out did nothing for me oddly . I realize that makes no sense Comment : I never timed it but on my mac there must be at least two delays one from self.validate the other elsewhere .", "Question : I m developing on Mac OSX 10.8 .

I didn t have to do that in earlier versions of Django I m currently running 1.7.3 on this project . Seems a bit messy but don t know of another way to stop the dev server and free the port resources Rgds Ross . .. . Answer : Django development server have multiple threads so when closing main process there might be some running threads in background . It happens when there is some request being processed some long-term request can hang or if you re using websockets or something connection might prevent closing thread . Check if all of your requests are properly closed before closing your server and it should shut down properly .

Answer : It looks like the request URL is incorrect : http : www.localhost.com http : www.localhost.com should probably be http : actual machine IP .com .. . .. . I d start searching there . You won t be able to access the VM s port 80 from a different lan using localhost as the hostname since localhost is probably already set in your hosts-file . If you want to test your dev environ remotely can I suggest either setting up Apache properly with port 80 as opposed to using django s dev server--privilege restrictions and all that can be circumvented with sudo and other bad practice or use a pre-built shared dev service like vagrant share .", "Question : I m trying to develop a simple plugin https : bitbucket.org weholt editra.djangomanagement for the Editra http : editra.org editor for django development . Right now it can create django projects and apps from within the editor . The editor is based on wxPython and I want to start the devserver from within the editor show a simple-form with the option to stop or kill restart the server . The goal is to minimize the need to do repetetive tasks in the console shell . My reason for doing this is that I am working in a Microsoft only company where you seldom do stuff using the command-line . Selling django is hard when I am in and out of the shell command-line to start restart the server syncdb migrate etc . To make the job of selling django to my co-workers and hopefully make development easier at least for the django developers who likes to work in an IDE I have started the work on a plugin for Editra . Right now the plugin adds a menu item called Django with two subitems create project and create app . A context menu is in the works which will give different options depending on the content of the file being edited right-click in a window holding settings.py will give you the option to start the devserver call syncdb migrate if south is installed create superuser etc . A right-click in views.py will give you options to help you generate views or templates in models.py scaffolding or generation of admin.py etc .

What I really like is to have a small window floating around with two buttons stop or restart which will -- stop or restart the devserver . Or a play and stop button inside the editor doing the same thing . The problem is controlling the devserver process from within the app .

I m using Firefox with the cache disabled about : config network.http.use-cache False so I m reasonably sure the issue is with Django . .. . Answer : Web servers themselves don t do caching . It is up to the application itself to decide how server-side caching works . In Django s case there are a number of options for enabling caching . The high level though is that Django sees a request for an URL generates the html string in response and stores that string in memory or a database - depending on the cache backend you set . The next time a request comes through for that same URL Django will check to see if that response lives in the cache and if it does will return that string . If it doesn t the process repeats . The idea behind providing @vary on decorators is that you change the lookup keys for finding a response in the cache . If you vary on user url . the algorithm goes something like this : .. . .. . The web server has no input into this type of caching . The other type of caching is client-side . This is where the web server is configured to return certain headers for specific types of resources like static content javascript images etc . The browser can then analyze those headers and decide to request the content or to use the content stored client-side . This generally doesn t apply to dynamic-content however .", "Question : In my development-environment I m getting intermittent failures for serving static files js scripts and css .

Answer : UltiDev Cassini is not actually dormant . Its successor UltiDev Web Server Pro http : ultidev.com Forums yaf topics21 Web-Server--PRO--Questions-and-Bug-Reports.aspx UWS has been under development for more than a year and has become closer to IIS in functionality not in size or complexity . UltiDev Web Server Pro test builds are being released once every few weeks and are fairly stable already . To comment on some of Sky s points : .. . .. . New UWS bypasses ASP.NET runtime when serving static content . UltiDev Cassini is not limited to loopback IPs host names . New UWS uses http.sys kernel driver as listener - same as IIS . UltiDev Cassini and UWS do queue requests but handle in parallel by pooled threads . Inability to serve WCF with WsHttpBinding is not a limitation of SimpleWorkerRequests but rather of WCF s assumption that whenever it s hosted in an ASP.NET AppDomain then it s hosted either IIS or original Cassini and nothing else . Attempts to convince MS to change that spanned more than two years and failed . In the end WCF hosted in ASP.NET appdomain concludes that it s only safe when it s under IIS while not making such assumption when it s hosted by a random .net process appdomain w o ASP.NET . Still WCF with BasicHttpBinding works alright . Cheers Vlad .", "Question : Currently our dev team set up all the websites they re working on in IIS on their local machine .

Answer : Another distinction I noticed is that Cassini runs as a 32-bit process and you have no control over it whereas you can control the application-pool of your IIS app to disallow 32-bit assuming your IIS is running on a 64-bit server . This becomes especially important if your web application is going to call APIs in 64-bit processes such as SharePoint Foundation Server 2010 . When you debug your web app with Cassini as your debug server you ll get The Web application at url could not be found . Verify that you have typed the URL correctly type errors when instantiating objects . If you debug using IIS with the app running in an app pool that runs as 64-bit with an identity that allows access to sharepoint database then you ll be able to debug properly .", "Question : Currently our dev team set up all the websites they re working on in IIS on their local machine .

Answer : It s a very good idea . Here are some reasons for : .. . .. . You no longer need admin access to your machine for web development it can still be helpful . It s much easier to test a quick change and continue work and faster iteration cycles are good http : www.codinghorror.com blog archives 000788.html . It can simplify setup and deployment of your development environments . The XP version of IIS has limitation that are not present in the Server version that Cassini side-steps . The only argument I know against is that there are a couple very rare edge cases where the Cassini built-in server doesn t exactly mimic IIS because you re using odd port numbers . I doubt you ll ever run into them and using Cassini as the primary dev environment does not preclude developers from also having access to IIS on the machine . In fact my preferred setup is Cassini first for most small work then deploy to my local IIS for more in-depth testing before moving code back to the shared source repository . Edit .. . Forgot about url re-writing . You do need IIS for that . And an example of a limitation of the built-in XP IIS is that you are limited to one site in XP can have multiple applications but that s a different thing . Comment : Cassini pipes every request to the ASP.NET runtime IIS doesn t . Cassini cannot use ISAPI...IIS does .

But sometimes you don t want these modules to execute for certain content most often static content . In this regard MS Cassini doesn t read obey system.webServer web.config settings like IIS7 does . I m particularly interested in these settings . Does UltiDev s Cassini http : www.ultidev.com products Cassini index.htm a separate payable product upgraded from MS Cassini web server read these settings and execute as the web.config tells it to .. .

What are the advantages of Cassini over IIS What are its disadvantages What are your experiences using Cassini as a production web-server Comment : ulti cassini or the microsoft one Comment : microsoft one.. . .. . Answer : As far as I know you cannot use Cassini in production because it listens for localhost requests only . You will have to modify source code and recompile the webserver by yourself . Another thing is that IIS is built on top of http.sys kernel-level library for maximum performance . I m not familiar with the latest Cassini versions but last time I checked it used slower managed TCP sockets . If your website is not very popular and Cassini has all the features you need why not.. . there is nothing wrong with Cassini . It s simple webserver but it s not the only alternative to IIS .

I was studying about the differences between ASP.NET Development server named Cassini and IIS server .

How to know my default server and change it Comment : Open project settings and switch to Web tab . Comment : Project settings You meant to say Project Properties .. . Answer : The default server are the APO.NET Development server Cassini but you can change that to either an IIS server or some other custom web server . You make these changes in your web project . You can also set the option Use IIS Express for new file-based web sites and projects in : Tools - Options - Projects Solutions - Web Projects .

Answer : I have run into the following limitations with the asp.net dev server : .. . .. . 1 . does not support virtual dirs . If you need them in your app IIS seems to be your only choice .. . .. . 2 . Classic asp pages dont run in dev server . So if you have a mixed web app like I have at my client right now IIS seems to be the solution .. . .. . 3 . If you need an admin UI to configure settings IIS works better .. . .. . Of course IIS requires that you be a local admin .", "Question : The server needs to be installed on Windows XP and has to host an ASP .NET 2.0 + ASP .NET AJAX 1.0 based web application . What is the simultaneous connection limit as opposed to 40 in IIS on XP .. . .. . Are there any other limitations short-comings that I need to be aware of .. . Answer : There are several problems with Cassini most common listed problems are a limit on the maximum concurrent connections and a lack of SSL support . There are also security problems stemming from how Cassini runs in a priveleged account so if an application served by Cassini is compromised the attacker gains control of the entire system . If you need to host an intranet application these issues probably aren t a big deal . However another feature lacking in Cassini is logging which I think is important even for intranet applications . This devx article http : www.devx.com dotnet Article 11711 1954 discusses how to implement your own logging by extending the Cassini source code yourself but doing so introduces other problems if it s not done properly . Comet Way the company I work for makes a product called the Neokernel Web Server http : www.neokernel.com that is a secure professional ASP.NET enabled web server designed for embedding in .NET applications . Like Cassini the Neokernel runs any ASP.NET web application that works under IIS and it addresses the above problems . It has features for handling other issues with embedding a web server in your application for instance starting stopping the server programmatically and APIs for extending the server with your own request processing code . It is not based on the Cassini source code . Maximum concurrent connections and a variety of other parameters can be specified via XML configuration-files .

Do not specity usb as a port when using a USB-serial connected programmer or bootloader because downstream of the operating-system driver these are not treated as USB devices but rather as serial ports . When you use such a device determine the com port or device node it is connected to perhaps by seeing which one appears disappears when you connect and disconnect it find out the baud-rate required by your programmer and issue a command such as .. . .. . COM1 or whatever on Windows .. . .. . Linux or OSX .. . .. . The device file on Linux would be something like dev ttyUSB0 or dev ttyACM0 while on OSX it tends to be dev tty.usbmodem or similar . .. . .. . The alternate solution you propose in comments of using -P avrdoper leverages the fact that your specific programmer offers an alternate interface which is not a USB-serial device in the eyes of the host operating-system but instead a custom USB protocol which at least some versions of avrdude know how to talk .

Under windows I can use it just fine without any of the flow-control pins routed . Have you tried it under Windows yet Comment : That is exactly what is happening I used ubuntu 14.04 and it detected it and worked fine using Arduino ide . It seems to be an issue with the ch340g driver .. . Answer : You may have a hardware issue . On OSX it may not be resetting in a proper way so bootloader not started and you receive programmer is not-responding error . To fix you need improve your hardware by changing reset circuit . With CH340 reset is driven by RTS and DTR pins . This also mean that you may try to look at your serial-port settings and enable flow-control . Comment : Do you know if it s a problem for the RTS and DTR pins to be floating All of the schematics I have seen so far online don t use them . But I wonder if that s what s causing my problem where the driver stops receiving transmitting data after several characters . Comment : What pins of ch340 are used for driving reset And what MCU Comment : I m using a PICAXE processor . The only pins I have connected to the CH340G are TX and RX . Everything else is either floating or connected to components only needed by the CH340G like the crystal and caps . There isn t a reset . They have a special protocol where they handshake on the TX RX lines to get the chip programmed . Comment : I have no experience with your processor . This topic marked as Arduino so i suppose you have a bootloader already burnt . This is how it works on standard boards suc as Mega Uno etc .

I also am running a kernel that supports the CDC-ACM module . I want to be able to flash new hex files onto the board . I have seen ArduinoDroid do this in his app . I have been able to flash using avrdude and the dev ttyACM file that is created using the CDC-ACM driver . However when I grant permission for my app to communicate with the arduino board the dev ttyACM file disappears . Which makes sense because I am now controlling it via Android s USB host api . I am looking for either a way to restore the dev ttyACM file or allow avrdude to use the dev bus usb file in order to flash a new hex file onto the board .

Answer : If you don t have the libusb filter installed for that device avarice won t be able to find it . You probably already have the Windows libusb port installed if not you can get it at http : libusb-win32.sourceforge.net go to its bin platform path and run install-filter.exe then select your JTAGICE3 device .

One interesting observation here is that if I have both the loop and the interrupt in my code at once if I call sei the LED does not blink as-if the OCF1A register was cleared prematurely . I m pretty sure it is irrelevant in this case but the fuses are as follows : E : CB H : D8 L : FF . I use avr-g++ to compile and the code is spread out between several files . Comment : I find code much easier to read if it uses the BV macro for bitmasks instead of manually shifting 1 . .. . Answer : You have two problems : .. . .. . 1 . You need to make sure main doesn t return even when it s not doing anything except waiting for the interrupt .. . .. . 2 . You need to enable interrupts via sei after setting everything up . Here s a working example I changed the LED port to PB5 because I ve tested this on an Arduino Uno and that already has an LED built-in Comment : Yes I know and I do both of the things You mentioned I simply included only the most relevant part of the code in my question . The problem of the interrupt not triggering still exists and I can see 3 possible sources of it : code makefile or fuses . At this point unless I m missing some weird registry setting the problem is probably not the code and I m not sure if it is even possible to cause such a problem through makefile or fuse settings .", "Question : The system sees something is plugged in when I plug and unplug it : .. . .. .

NOTE : I had to set it to open the link in a new window in the fiddle as jsfiddle wouldn t let google load in the iframe so allow popups . Fiddle : http : jsfiddle.net codeowl HLaRx 4 .. . .. . HTML : .. . .. . JavaScript : .. . .. . Please help me to resolve this issue . Here is an example of the nav panel I am trying to create : enter image description here http : i.stack.imgur.com lOaYl.png .. . .. . Regards .. . .. . Scott .. . Answer : Not sure when it stopped working but I would say that current behavior is pretty understandable despite maybe not what you would like . Menus expect that what you have inside is a menu option not a full HTML . So when you set openOnClick to true in opposition to default that is mouse over what Kendo UI has to do is intercept the click event on any HTML element on that menu . As consequence you have that it does not open the URL as you expected . So my question why do you need to define it as you are doing Would be possible something like this instead : .. . .. . Example here : http : jsfiddle.net OnaBai HLaRx 6 Comment : Thanks for responding mate . See pic I added to the question to demonstrate the nav I have created that used to work . Basically there are a lot of menu items and a number of top level navs that unfold like this.. . it makes finding things easier than dealing with cascading menus . You guys do the same thing on the kendo site click on products : telerik.com kendo-ui http : www.telerik.com kendo-ui but it looks like your not using the kendo-menu on the kendo site.. . Comment : FYI this issue was acknowledged as a bug and resolved by Telerik support . Comment : @user2109254 just about You guys do the same thing on the kendo site just to let you know that I have nothing to do neither with Telerik nor with Kendo UI .

Html : .. . .. . Js : .. . Answer : There isn t really a good way to do that . It is a bit of a CSS limitation with the way the elements are stacked . The table uses a div around it to provide the vertical-scrolling overflow : scroll and the dropdown for the menu is inside that wrapper so when it is open it will be cut off by the bottom of the table . Plus the individual table cells are set to overflow : hidden by Kendo as well . If you just have a dropdown of 3 items you might want to use a Kendo DropDown widget instead .

Answer : Generally speaking with Node if it s a common problem to solve someone s already gone to the trouble to write and publish something on npm . For example request-cookies https : www.npmjs.com package request-cookies In particular I think you ll find the toJSON method most helpful though admittedly the package s documentation is rather light .

For the first few hundred requests this always works fine but then I get lots nad lots of either ENOTFOUND or timeout errors and I think the issue might be the way my code is dealing with all these requests . I ve batched them in a queue with timeouts so the requests happen relatively slowly it helps a little bit but doesn t solve the problem completely . Do I need to destroy the body response objects to free up memory or something Comment : To clarify : Do you send all the requests immediately Did you consider restricting the number of concurrent requests e.g . with async Comment : you re most likely running into provisioning issues with the API you re calling Comment : @h0ru5 I ve done something similar in that I ve created a queue array and a script that loops through it doing 25 calls every 5 seconds . Comment : Are you absolutely sure you re not hitting api limits This usually happens either due to the target network limiting you or being overloaded or your server local network being overloaded . at 25 5 sec it s probably not a network issue more likely to be limiting . Comment : @MikeDinescu Possibly but see comment above . .. . Answer : I ve encountered similar issues with an API I was using and it ended up being what some here suggested - rate limits . Some APIs don t return readable errors on rate limits as they provide certain amount of resources per client and when you ve used it all up they can t even send you a bad response . This happened even though I ve stayed within the published rate limits per day but turned out they have an unwritten limit per minute or more like - just unable to process so many requests . I answered it though by mocking that API with my own code placing it in the network so it will maximize the similarities and as my mocked code didn t do anything I never got any errors in the NodeJS server . Then I put it some countdowns and timeouts when it was needed . I suggest the same to you . Remember them having a per hour limit doesn t mean they don t have a different per second minute limit .", "Question : I use MongoDB as the back-end database for my node Express application .

I need mocha to send for example 100 HTTP requests all at once and then have 100 callbacks waiting for response data . And then after all 100 of those calls are done I need to run another series of 100 HTTP requests . What I know about Mocha : each side-by-side describe function-call runs synchronously . Within one describe I run the 100 HTTP requests using async which is what most Stackoverflow responses told me to do . Right now I am having trouble with just getting these HTTP requests to run in asynchronous . Each it is supposed to be asynchronous but it is definitely not the case-when waiting for request data .. . .. . Basically the first 100 HTTP requests register accounts and the next 100 retrieve info for each respective account . I don t know when to call done and when to call callback pertaining to async.map . Anybody know what to do here .. . Answer : Maybe I m wrong but I do not see the point here to use async.map in your code . Given 100 requests send all of them in a single test .. . .. . In case your test case is Send 100 requests and test that they all return you have to use async in your test . Given a list of 100 calls test each single call .. . .. . If what you want to do is to have a list of calls and have a it test for each of them then you can just produce a new it clojure for each call . mocha will register the it tests and then execute them . Comment : yeah you re right I took out the async.map . But these requests are sent in one after another . I have two terminals up one for the API and the other for mocha tests sending requests and the API is not receiving all the calls asynchronously . request is blocking every subsequent call until the previous is returned Comment : If you want concurrent calls I d recommend to group them : even if you fire them all together usually there s a maximum number of calls that can be open in parallel . I believe that 100 is far above that cap . Comment : well I can t even get 2 concurrent calls with this though Comment : Ok then I think the answer above is not right as it is . I will update it . Comment : @Jeremy it is updated now", "Question : See bottom of question for an update based on comments answers : This question is really about the possibility of hidden threads that do not execute callbacks . .. . .. . .. . .. . I have a question about a potential arcane scenario involving the Node Request module https : www.npmjs.com package request in which : .. . .. . A complete HTTP request is constructed and executed over the network taking however many ms or even seconds .. . .. . .. . before a single function is executed at runtime on the local machine typically in the nanoseconds - see below for details .. . .. . I am posting this mostly as a sanity check just to make sure I am not misunderstanding something about Node JS Request module code . From the examples in the Request module https : www.npmjs.com package request examples see the SECOND example in that section is this : .. . .. . I have indicated my arcane scenario in the code snippet . Suppose the Node process hangs at the point indicated but that Node internally in a hidden thread invisible to Javascript and therefore not calling any callbacks WAS able to construct the request and send it over the network suppose the hang continues until a response in two chunks say is received and waiting to be processed by Node . This is the scenario that is certainly arcane and that I m not sure is even theoretically possible . Then suppose that the hang ends and the Node thread above wakes up . Further suppose that somehow Node was able to process the response all the way to the point of executing the callback function in the code above yet without moving past the hanged point in the code in the original code path -- again if this is even theoretically possible . Is the above arcane scenario theoretically possible If so wouldn t the data packets be received over the network and combined ready to be passed to the callback function before the data event was scheduled on the object In this case if it s possible I would imagine that the data event would be missed . Again I understand that this is an arcane scenario - perhaps it s not even theoretically possible given the internal mechanisms and coding involved . That is my question - is the above arcane scenario with its extremely unlikely race-condition nonetheless theoretically possible I ask just to make sure I m not missing some key point . Thanks . .. . .. . UPDATE : From comments answers : I now have clarified my question . The arcane scenario would require that there is a HIDDEN thread which therefore CANNOT execute any USER code including CALLBACKS that constructs the request sends it over the network and receives the response - WITHOUT having any callbacks to trigger including the data callback - and stops short just at the point that the response callback is ready to be called waiting for the single visible JS thread to wake up . Comment : You might want to read developer.mozilla.org en-US docs Web JavaScript EventLoop https : developer.mozilla.org en-US docs Web JavaScript EventLoop Comment : @FelixKling Thank you . I just want to be certain that there is no hidden thread that processes the request and sends it over the network just up to but not including the point of the callback which I understand is in the single JS thread . Comment : I don t really understand how you think that a data event could be missed . You mean the packets are received before the handler is installed Comment : @Bergi - Exactly . I trust this can t actually occur I just want to be sure I understand why . Because though all USER code must occur in a single thread from the other comments answer and all CALLBACKS must execute in that same thread where does it say that there cannot be a hidden invisible internal thread that does processing up to but not including the point at which a callback needs to be called Comment : What does thread hangs here mean node.js doesn t just hang . There could be an infinite-loop but execution doesn t just hang . .. . Answer : There s only one thread involved in Node.js an event-loop is used to process tasks that run asynchronously and nothing queued will ever interrupt anything already running . So no there is no race-condition there . Comment : Internally to the Node implementation I think there must be additional threads - at least so that some thread can block on the operating-system s event or condition etc . object . These threads would not be visible to the Javascript Node code . However - there is just one thread that executes the Javascript code correct If so - is it true that the construction of the HTTP request occurs inside this Javascript thread or could it occur inside a hidden thread in the Node internals Comment : There are other threads internal to node.js to make certain things wrok . In fact async file I O uses threads . But it is my understanding that networking does not use threads it uses events . Comment : @DanNissenbaum : When it comes to network I O there are no additional threads visible or otherwise . It s all single thread that executes the javascript AND handle network requests - they take turns . The only exception is disk I O which the node developers have chosen to implement as threads to simplify cross-platform support of async disk I O Comment : @DanNissenbaum : See this for an explanation of how node works : stackoverflow.com questions 29883525 http : stackoverflow.com questions 29883525 i-know-that-callback-function-runs-asynchronously-but-why 29885509 29885509 Comment : @DanNissenbaum : Not only those there can also be UI events browser and thread job completion events web workers .

Answer : This is caused when your request response is not received in given time by timeout request module option . Basically to catch that error first you need to register a handler on error so the unhandled error won t be thrown anymore : out.on error function err handle errors here . Some more explanation here https : github.com request request issues 636 . In the handler you can check if the error is ETIMEDOUT and apply your own logic : if err.message.code ETIMEDOUT apply logic . .. . .. . If you want to request for the file again I suggest using node-retry https : github.com tim-kos node-retry or node-backoff https : github.com MathieuTurcotte node-backoff modules . It makes things much simpler . If you want to wait longer you can set timeout https : github.com request request requestoptions-callback option of request yourself https : github.com request request requestoptions-callback .

Answer : Since you said they had issues and are trying to prevent scraping or something you may be subject to those efforts . Why would you need to keep hitting their page so often I think if you really want it to work you are going to need to fool their anti-scraping systems firewall or whatever . So you can try using a droplet in a different data center city and also try adding headers to imitate a web browser . User-Agent would be the first I would try . Also make sure you don t hit their site too often and get rate limited . Comment : To address your first question I don t believe I am making a whole lot of requests . Definitely not in the hundreds but on the other hand way more than a typical user interfacing with their site via a browser . Either way I am definitely trying to minimize the number of requests I am making in case they do have some sort of detection system set in-place although I am inclined to believe they are not that capable . Comment : To address your main point : In my post you will find that I actually have tried setting the User-Agent under Additional Findings . However it does not seem to yield better results than sending a request without that header attached . This combined with the fact that I have never had problems making requests from my local machine i.e . I get a 100 response rate using the script mentioned in my post leads me to suspect that HOW I m making the requests is not the problem . That said I m also not sure if changing the droplet s location will do what I m looking for . Comment : Anyway I appreciate the time you took to make a reply and I DEFINITELY welcome ANY more suggestions and ideas you might have . Thanks a lot :", "Question : null .. . Answer : My app uses NodeJS Express and Request . I m downloading a bunch of data from an API all within the API s usage limits . It s around 3 000 requests and they all happen fairly simultaneously . After about 1 000 of those requests which return data fine I start seeing Error : read ETIMEDOUT for almost every request . I can manually do a CURL request for the API endpoint from my terminal and it gets a response just fine . Is this a known issue with NodeJS Perhaps an agent pooling issue Or is this likely some sort of call limit on my API s end Comment : 3 000 simultaneous API calls is a lot that would put a burden on the vast majority of APIs out there not to mention the bandwidth issues on both ends depending on how much data is involved . It s likely you re just flooding the pipes or burying the server for a moment . Comment : @EdCottrell Hrm they mention an hourly rate limit for their API but nothing else . it s a CRM so I would ve assumed this isn t something uncommon . What s the suggested solution here using a timeout interval to batch the requests into more manageable chunks Comment : Yep . Also since you said it s a lot of data keep in mind that the problem might be on your end . If each response generates say 100k of data that would be 300 MB of data . Even if the server can handle it it might take so long to get back to your machine that it looks like it timed out because the pipe is full . Comment : If all these requests are to the same endpoint then the default http module in node.js will only make a max of N requests at a time and will queue the rest . It s pretty easy to imagine that if you queue up 3000 of them and they re only being sent 10 at a time that some of the other 2990 in the queue might timeout before they get their turn . I d suggest you only send N at a time where you will have to decide what the value of N should be . Of course it s also possible that you re overwhelming the server too but I d first make sure you don t have a problem on your end .

I m in full control of the Raspberry Pi . Do you have a link available where I can check on acceptable ports so I can shortcut this problem I have been out of commission for days .

One is tcServer and second is tomcat server . What is the use of the two servers and why these two and what are their purpose Is it mandatory to use these two .. . Answer : Although hybris provides you 2 application servers Tomcat tcServer to choose from and use for your development testing by default only Tomcat is configured to be used without doing any additional configuration i.e . when you build and run hybris server without any change in configuration Tomcat is used . If you want to switch to tcServer which is another powerful application server you can update the configuration and switch to it as it is readily available in your hybris commerce suite download . In case you like to use any other application server e.g . WebLogic you will have to download it separately and deal with the licensing terms .

You should comment on my answer so that I get notified . Let me know if you still have problems but normally the first time you run any ant command in the hybris platform it will check for the configuration and if it is not present ask for a configuration templage to use which defaults to develop which is an empty localextensions.xml .

The file describes a custom language . My goal is to use that yacc file to create a parser for my custom text area in my Java application . The endgoal is to show errors when the syntax is incorrect . I m currently using RSyntaxTextArea which handles highlighting rather nicely based on my own implementation not the yacc file but creating a parser that can detect every possible error the user can make is a much harder task . The way I see it I have three options : .. . .. . 1 . The best case scenario would be if somehow I could use the yacc file I have directly in my Java application . 2 . The second best case would be if there d be a way to parse the yacc file to a format I can easily use in Java . I found BYACC J which creates a Java class from the yacc file but the file I got was riddled with syntax errors missing functions variables etc . so that didn t work out too well . 3 . As I see it the third option would be to learn YACC and another parser-generator that I can use in Java and rewrite the whole thing in that . Learning new things is never a bad thing but since my time is not endless and these compiler compilers seem to have a rather steep learning curve I d only want to invest time in it if there s no way to use the YACC definition directly . As I ve found there are quite a lot of potential options out there between JavaCC Jacc CUP ANTLR4 and probably lots of others I d want to choose one that s as close to yacc as possible to reduce the implementation time .

Answer : Bison the yacc-compatible parser-generator most commonly mistakenly called yacc can generate Java parsers https : www.gnu.org software bison manual bison.html Java-Parsers . Having said that I ve never tried it so I have no idea what problems you would run into . A yacc grammar includes semantic rules in the target language if you have an existing grammar the semantic rules will probably be written in C . Yacc grammars also depend on the existence of a scanner often created with flex or JFlex for Java which works in a very similar manner . In order to use a Java-based solution even one which uses the same grammar syntax you would need to rewrite all of the semantic actions in your existing yacc grammar as well as rewrite the accompanying scanner . That would also be the case for BYacc J you cannot just provide a C-targetted yacc grammar file to a parser-generator and expect to get a functioning Java parser . So you would definitely need to learn how yacc bison flex work . Note : Bison and friends are designed to parse syntactically-correct programs . Obviously they can detect a syntax-error but recovering from the syntax-error to continue the parse is a lot trickier for syntax-highlighting you definitely want to be able to detect more than one error if at all possible . So you may well find that your existing yacc grammar is only a start .", "Question : How much time would it take to write a C++ compiler using lex yacc Where can I get started with it Comment : Good luck .

Comment : some help : Let s Build a Compiler by Jack Crenshaw at compilers.iecc.com crenshaw http : compilers.iecc.com crenshaw .. . Answer : A long time and lex and yacc won t help .. . .. . If you have the skills to write a compiler for such a large language you will not need the small amount of help that lex and yacc give you . In fact while lex is OK it may take longer to use yacc as it s not really quite powerful enough for C or C++ and you can end up spending far more time getting it to work right than it would take to just write a recursive-descent parser . I believe lex and yacc are best used for simple grammars or when it is worth the extra effort to have a nicely readable grammar file perhaps because the grammar is experimental and subject to change . For that matter the entire parser is possibly not the major part of your job depending on exactly what goals you have for the code generator . Comment : I completely disagee . As do the gcc team .

Ruby has a complex grammar and the main implementation does use yacc . I ve written parsers both ways certainly there are no easy always do it this way answers I just think it s important to realize that the parser will be roughly the same amount of effort either way .

Comment : some help : Let s Build a Compiler by Jack Crenshaw at compilers.iecc.com crenshaw http : compilers.iecc.com crenshaw .. . Answer : There are many parsing rules that cannot be parsed by a bison yacc parser for example distinguishing between a declaration and a function-call in some circumstances . Additionally sometimes the interpretation of tokens requires input from the parser particularly in C++0x . The handling of the character sequence for example is crucially dependent on parsing context . Those two tools are very poor choices for parsing C++ and you would have to put in a lot of special cases that escaped the basic framework those tools rely on in order to correctly parse C++ . It would take you a long time and even then your parser would likely have weird bugs . yacc and bison are LALR 1 http : en.wikipedia.org wiki LALR 5Fparser parser generators which are not sophisticated enough to handle C++ effectively . As other people have pointed out most C++ compilers now use a recursive-descent http : en.wikipedia.org wiki Recursive 5Fdescent parser and several other answers have pointed at good solutions for writing your own . C++ templates are no good for handling strings even constant ones though this may be fixed in C++0x I haven t researched carefully but if they were you could pretty easily write a recursive-descent parser in the C++ template language . I find that rather amusing . Comment : If I am not mistaken gcc switched to using a recursive-descent parser sometime late in the 3.x series . Comment : gcc uses lex and yacc for the C++ front-end . For all the ambiguities you mention there are explicit commands to resolve the conflicts . Personally I doubt there is a better framework for parsing C++ out there . BUT writing a C++ lexer parser without lots of compiler experience is a non starter for a single developer using lex yacc its just to large and complicated . Comment : @Martin York in fact the bison yacc parser was replaced with a recursive-descent parser in gcc-3.4 - gcc.gnu.org gcc-3.4 changes.html http : gcc.gnu.org gcc-3.4 changes.html Comment : Recursive descent parsers are also much much easier to understand . In fact if you re interested in language development I d probably recommend starting with hand-generating a recursive-descent parser for a relatively simple grammar . Comment : @kyoryu : Recursive descent parsers are NOT that much easier to understand than the pure grammar especially for an artifact of the scale of C++ . You really want a parser-generator driven from the language definition in terms of BNF rules . The people that say C++ is hard to parse are those that use YACC and variants and those that tangle name type resolution with parsing . GLR parser generators allow you to build a very good parser using the BNF rules and isolate name type resolution this separate makes each task a lot easier although not easy . See my answer here .", "Question : Yacc does not permit objects to be passed around . Because the union can only contain POD types complex objects must be new d and passed around by pointer .

Does anyone know of any better yacc tricks to solve this problem Please don t tell me to choose a different parser . .. . Answer : I love Yacc but the discriminating union stack does present a challenge . I don t know whether you are using C or C++ . I ve modified Yacc to generate C++ for my own purposes but this solution can be adapted to C . .. . .. . My preferred solution is to pass an interface to the owner down the parse-tree rather than constructed objects up the stack . Do this by creating your own stack outside of Yacc s . Before you invoke a non-terminal that allocates an object push the owner of that object to this stack . For example : .. . .. . Everything that wants an expression has to implement the IExpressionOwner interface and push itself to the stack before invoking the expression non-terminal . It s a lot of extra code but it controls object-lifetime . Update .. . .. . The expression example is a bad one since you don t know the operation until after you ve reduced the left operand . Still this technique works in many cases and requires just a little tweaking for expressions . Comment : can you show how this would be used in the .ypp file Comment : I accept that the best solution is to create a parallel data structure outside of the syntax parser . It makes the parser non-reentrant since the parser must access global-variables but I can live with that .", "Question : What is the difference between Flex Lex and Yacc Bison . I searched the Internet wildly and I didn t find any solid answer . Can I install pure Lex and Yacc on Ubuntu or I can install only flex and bison . I am confused .

Answer : There are some differences between Lex and Flex but you have to be abusing Lex to run into the problems with Flex . I have a program which abuses Lex and doesn t work under Flex therefore . This is primarily in the area of input lookahead in Lex you can provide your own input code and modify the character stream Flex won t let you do that . Yacc and Bison are pretty closely compatible though Bison has some extra tricks it can do . You probably can t find legitimate copies of the original AT T versions of Lex and Yacc to install on Ubuntu . I wouldn t necessarily say it is impossible but I m not aware of such .

Is that correct that Flex Yacc are the most proper way to do it Will it be slower than writing a Shell or Python script using regexps which may become big pain as I suppose if the number of additional keywords becomes bigger and their effects would be rather different provided that I have zero experience with analysers parsers though I know how LALR does its job Are there any good materials on Lex Yacc that cover similar problems All papers I could find use the same primitive example of a toy calculator . Any help will be appreciated . .. . Answer : That entirely depends on your definition of effective . If you have all the time of the world the fastest parser would be a hand-written pull parser . They take a long time to debug and develop but today no parser-generator beats hand-written code in terms of runtime performance . If you want something that can parse valid C within a week or so use a parser-generator . The code will be fast enough and most parser generators come with a grammar for C already which you can use as a starting point avoiding 90 of the common mistakes . Note that regexps are not suitable for parsing recursive structures . This approach would both be slower than using a generator and more error prone than a hand-written pull parser . Comment : and the last 10 will take you another year because of C s context sensitivity . Ask the GNU guys .", "Question : How does one make a comment in Lex and Yacc So far I haven t tried Yacc but in Lex I have tried comment and comment but neither of these compile . I am on a Mac using the builtin Lex and Yacc compilers or maybe the X-Code ones I don t know . What is the correct syntax for comments in Lex or Yacc or preferably both .. . Answer : Any C comment is acceptable as a comment anywhere in a program in both Yacc and Lex BUT : .. . .. . When using Lex or Yacc whitespace is important so comment written into your program touching the LHS of your text will NOT WORK .. . to make it work you must add a tab or space to the beginning of the line to shove it to C code and not Lex or Yacc code . gcc is a nice compiler and loves you very much so it accepts comment comments Lex and Yacc are not nice . these comments while will work in a C program will NOT WORK", "Question : Yacc does not permit objects to be passed around . Because the union can only contain POD types complex objects must be new d and passed around by pointer . If a syntax-error occurs the yacc parser just stops running and references to all of those created objects are lost . The only solution I ve come up with is that all new d object inherit a particular base-class be added to a container when allocated and if there is an error everything in that container can be deleted . Does anyone know of any better yacc tricks to solve this problem Please don t tell me to choose a different parser . .. . Answer : Use smart-pointers http : www.boost.org doc libs 1 36 0 libs smart ptr smart ptr.htm Or if you re uncomfortable depending on yet another library you can always use auto-ptr http : www.gotw.ca publications using auto-ptr effectively.htm from the C++ standard-library .

A simple parser in F http : strangelights.com blog archive 2006 05 11 1302.aspx", "Question : Is there a simple way for integrating Bison Flex Yacc into XCode I want to write my own language to be parsed which interacts with my ObjC objects . But the tools will only take STDIN as input and will only produce C code instead of ObjC . They re basically only seem useful for command-line tools otherwise they need massive pain to override the output every time I regenerate the parser code . .. . Answer : Xcode does know how to process yacc and flex files and will automatically compile the generated code files into your project . The trick is figuring out which extensions it expects . In Xcode 4 click on the top-level item in the source list to get the project settings . Click your target in the next list then Build Rules in the table view header . Scroll down to System Lex rule and System Yacc rule then hover the cursor over source files in each of those to get a tool tip with the extensions it uses for that rule . What That wasn t obvious For Lex it s : .l .lm .lmm .lpp .lp .lxx .. . .. . For Yacc it s : .y .ym .ymm .ypp .yp .yxx .. . .. . If you have any Objective-C code in your lex yacc files you ll need to use the . m extension to tell Xcode to generate a .m file likewise . mm for Objective-C++ . I m guessing . pp . p and . xx are all C++ . From what I ve seen this Just Works no Makefile needed . If you want to keep the .flex extension you can click the Copy to Target button in the Lex rule and make a new rule for that extension . Now the fun part is trying to integrate yacc into your code . By default the yyparse function which makes the whole thing go expects input from STDIN unless you jump through a bunch of hoops to make it work otherwise . If you re dead-set on using yacc there s plenty of info on the web about how to bend it to your whims . But you might wind up with fewer keyboard dents on your forehead if you use a modern parser-generator like lemon http : www.sqlite.org src doc trunk doc lemon.html . The syntax is based on yacc s and it s LALR 1 whatever that means so everything you know about shift reduce conflicts still holds . I found it much easier to work with than yacc flex . Edit : I seem to recall that Xcode didn t add the .l file to the build phase automatically but it did add the .y file . Check your build phases by clicking the top-level item in the Xcode source list click you target click the Build Phases table header then expand the Compile Sources row . If your .l file isn t in there drag it in from the source list .", "Question : I am doing project in SENSE for that i have to install Lex and Yacc . If you can help me how to install in Ubuntu .

Lexical analysis is done using jflex and I m wondering which yacc-like tool would be best most efficient easiest to use etc . for doing syntactical analysis and why . .. . Answer : If you specifically want YACC-like behavior table-driven the only one I know is CUP http : www2.cs.tum.edu projects cup . In the Java world it seems that more people lean toward recursive-descent parsers like ANTLR http : www.antlr.org or JavaCC https : javacc.java.net .

What should be declaration of the yymore in yacc Comment : Why You should only be using it in the lexer . In the parser you ll often be a token ahead of yourself anyway so it won t make sense . Comment : @EJP If suppose in yacc after encountering certain token I want to store further read tokens in a string till i encounter some specific token . Then I would have to keep adding read strings to yytext using yymore function till I stop . So how to call this yymore function from yacc file . Comment : I do not want an implementation of yymore in yacc . I want to call lexer yymore function from yacc file . Comment : I ve already told you it doesn t make sense and I have also told you why . You need to use parsing tools for parsing problems and lexical tools for lexical problems . There is nothing here that suggests this is a parsing problem and if it is yymore is not the solution . Comment : I understood now . Thanks .. . Answer : You can only call yymore inside the action of a flex rule it indicates that the rule does not complete the token so that the next matched rule will append to the token rather than starting a new one . It makes no sense to call yymore in a parser action parser actions are only executed when the scanner has returned a complete token so there is no current token which can be extended . If I understand correctly what you are trying to do you will need to create a context-dependent scanner using a start condition http : flex.sourceforge.net manual Start-Conditions.html Start-Conditions . In that start condition tokens are appended into a single token until you find the token which is supposed to terminate the concatenation . You cannot call the BEGIN macro in the parser either but you can export your own function from the scanner which sets the start condition . Be aware that semantic feedback of this form is not very robust since the parser may well have already read the following token as a lookahead token . yacc and bison handle lookahead tokens differently yacc always reads the lookahead token while bison only does so if it is needed .", "Question : I m looking for the C grammar in GCC source code more specifically for the grammar in the yacc bison form .

But if the whole point is to scatter them around randomly then you will have to keep track of positioned elements and take that into account when calculating their position .

Comment : @thirtydot : Or even less when there s definitely lots of space for the elements .

I am trying to merge overlapping elements in the tuple list . Here is a code that i am working on which uses foldleft to merger overlapping tuple list from the list.The merging doesn t seam to be working as it misses out some elements of the tuple list.Each tuple list contains 4 tuples present in them . Each tuple list in the list often overlapping as they are generated from a bigger list using sliding function . here is the example data which i am using : .. . .. . The merged list look like : .. . .. . Update 1 : .. . .. . Overlap : If two list of tuples have the 3 or more exact tuples present in both list then they are supposed to be overlapping list of tuples.But there should not be any difference when two list is merged.If one of the tuple values in both list have same integer but different char then they shall not be merged . Merge : Combining two or more list of tuple list when they overlap . Update 2 : I have come up with a small solution but not sure how efficient is it . so when i print the above code i get tuple list grouped in this manner . i have printed only the index of the each tuple group that should be merged . Result generated : ListBuffer 0 2 0 3 1 4 2 5 3 6 4 7 5 8 6 9 7 10 .. . .. . here is the list of tuples with their index that was used .. . .. . So now all i had to do was use the interGrps link the groups based on second value and finally replace the indexes with list of tuples. . Comment : The definition of your merged list and what you mean by overlap is very unclear especially as you don t give the totals . Comment : Sorry still unclear . Do they overlap when there is a difference in char with the same integer value It s a bit confusing because you use merge there . Is it correct to say two lists overlap if they share 3 or more tuples and any pair of tuples with the same number do not have different characters Comment : Yes two lists overlap if they share 3 or more tuples and any pair of tuples with the same number do not have different characters Comment : But that produces more output elements not less as now less things overlap . See my updated question - which still won t give the right answer Comment : i have updated the question with answer i ended up with . .. . Answer : The following code follows I think the description of your algorithm . However it does not give the same output so there s something still to clear up about wha you want .. . .. . First the test data .. . .. . Now a method to implement If two list of tuples have the 3 or more exact tuples present in both list then they are supposed to be overlapping list of tuples . Then using something I wrote over here http : stackoverflow.com a 35919875 21755 that groups elements that match according to the predicate .. . .. . we can get a list of lists of overlapping elements .. . .. . Then we write a function to merge a list of overlapping tuples : .. . .. . doing a union of the tuples by adding any that aren t already in the accumulated result and adding up the ints . The .sorted is just to make it easier to visually review the result .. . .. . Then merge the overlapping entries .. . .. . Giving this but that isn t the output you have EDIT : Following the comments here s an updated isOverlap . However it means less overlaps than the original so more elements in the final merged output so it s still not right : Comment : Thank you for the reply . I see the problem.The fault is on my side sorry as i missed one condition in the explanation . When i merge the list of tuples they should have minimum 3 overlaps but with no difference . ie in your output the first list of tuple has 348 c 348 t .I shall update the question Comment : Sorry not clear what you mean there : Comment : Its okey thank you.When two tuples are merged they are two conditions- 1 . They should have more than 3 intersections as per given in description . 2 . If any tuple in both list has same integer but a different string char as its value then they cannot be grouped together . Comment : Oh cool so it s just a matter of changing isOverlap . However that will give more overlapping groups so a longer final merged list . But my code already produces a list longer than your output in the question so that doesn t seem right . Comment : I am not sure because when i tested with the conditions i mentioned i always ended up with less sequences than there should be . So I had come up different solution without making it soo complex .

Given : .. . .. . passing the argument value 1 would match both the first pattern x and the 2nd pattern : xs - so that would mean the function has overlapping patterns even though both patterns can be matched . What makes this confusing is that although the patterns are by the definition above overlapping GHC does not show any warning about them being overlapping . Reverting the 2 pattern matches in the last function does show the overlapping warning : .. . .. . Warning : .. . .. . It is almost as though GHC consideres the patterns overlapping if a previous pattern makes it impossible to match a pattern which occurs later . What is the correct way to determine if a function has overlapping patterns or not .. . .. . Update .. . .. . I am looking for the overlapping pattern definition used in fp101x course . According to the definition used in fp101x the following function has overlapping patterns : .. . .. . This is in contradiction with GHC definition of overlapping pattern which does not consider it to have any overlapping patterns . Without a proper definition of what overlapping pattern means in the fp101x course context it is impossible to solve that exercise . And the definition used there is not the GHC one . Comment : GHC warns about pattern overlapping when it actually detects pattern inclusion -- precisely when one case in the pattern becomes unreachable since it only covers values already dealt with in previous cases . Comment : @chi : that would be what GHC consideres to be pattern overlapping . The first function definition seems to be considered pattern overlapping also . Is there a formal definition of what pattern overlapping is Comment : From your description it seems like they don t want any sort of overlapping . Then you could do something like use the pattern last : x : xs last x : xs last x x or use guards . .. . Answer : The updated question clarifies the OP wants a formal definition of overlapping patterns . Here overlapping is meant in the sense used by GHC when it emits its warnings : that is when it detects that a case branch is unreachable because its pattern does not match with anything which is not already handled by earlier branch . A possible formal definition can indeed follow that intuition . That is for any pattern p one can first define the set of values denotations p matching with p . For this it is important to know the type of the variables involved in p -- p depends on a type environment Gamma . Then one can say that in the sequence of patterns .. . .. . the pattern p is overlapping iff p as a set is included in q0 union .. . union qn . The above definition is hardly operative though -- it does not immediately lead to an algorithm for checking overlaps . Indeed computing p is unfeasible since it is an infinite set in general . To define an algorithm I d try to define a representation for the set of terms not yet matched by any pattern q0 . . qn . As an example suppose we work with lists of booleans : .. . .. . Here the remaining set did not change so the last pattern is overlapping . As another example : .. . .. . As you can see in each step we match each of the remaining samples with the pattern at hand . This generates a new set of remaining samples possibly none . The collection of all these samples forms the new remaining set . For this note that it is important to know the list of constructors for each type . This is because when matching with True you must know there s another False case remaining . Similarly if you match against there s another : case remaining . Roughly when matching against constructor K all other constructors of the same type remain . The above examples are not yet an algorithm but they can get you started hopefully . All of this of course ignores case guards which make the overlap undecidable pattern guards GADTs which can further refine the remaining set in quite subtle ways .", "Question : I use a RelativeLayout to place views using LayoutParams and setting the top y coordinate and left margin x coordinate .

Answer : I have padded out your example with a second Person id and shortened the column names a bit to make the code a little shorter : .. . .. . So working on the above data you could apply the following query : .. . .. . Contrary to other RDBMS MySql has a certain procedural feel to it when it comes to select statements . You can actually use variables @id and @ed in them that will-change their state over time in this context the order by clause at the end is extremely important . The basic idea behind this query is : start with a certain pid and list the intervals in the order of increasing start dates sd . Always remember the maximum value of the end date ed in variable @ed . Now with each new interval check whether there is an overlap with the previous interval i . e . check whether the current start date sd is smaller than the previous maximum end date @ed and calculate the interval days accordingly . The first case clause is necessary to reset the variables @id and @ed whenever the current pid changes . Subquery const just sets the variable @id in the beginning .

Output memmove can be very very useful . .. . .. . This output is the same as it is for memmove .And here are my confusions : .. . .. . 1 Why is output same for both Since there is no intermediate buffer used in case of memcpy I expect the copy to start by copying the character in str+15 position to the str+20 position overwriting what is there character in str+16 position to str+21 position and so on till character in str+20 position which has by now changed to the character in str+15 position to be copied to the str+25 position .But it s not so there is no overwriting and it s acting as-if an intermediate buffer is used to write the exact original string.Here s an illustration : .. . .. . Then why is memcpy copying it as memmove can be very very useful instead of memmove can be very very very v 2 Now a minor secondary question arising from it.The following is said about memmove LINK http : www.cplusplus.com reference cstring memmove .. . .. . Copying takes place as-if an intermediate buffer were used allowing the destination and source to overlap . .. . .. .

Comment : Unless an intermediate buffer it will be implementation defined . really cant tell . Comment : @Koushik Since the second parameter of memcpy is a constant why are we even allowed to write onto that without generating errors for memcpy Comment : compiler has no way of knowing which memory you are accessing . it only has the pointer to the source . you are saying that the source wont be modified by decalring the second parameter as const but you break the promise soo after which compiler cant help.so doing anything to a const declared location is UB even if the const location is not read only Comment : you can do this const int i 10 ..... . int ptr i . . ptr 100 . . printf d i . which is UB . but i broke the covenant . compiler warns but i can do it . you cant even be sure wherther it will print .. . Answer : If the objects overlap the behaviour of memcpy is undefined . There s little point in trying to reason about undefined behaviour . Since it is undefined it defies reason . You know the rules and they are clearly documented . If the objects overlap use memmove . As for the use of as-if that is to specify behaviour but not place any limitations on implementation . This allows the library implementor to use whatever method they see fit so long as the end result is the same as using an intermediate buffer . For example the implementation could detect that the objects do not overlap and so avoid using an intermediate buffer for performance reasons . Comment : The prototype of memcpy is void memcpy void destination const void source size-t num .ie the source is supposed to be a constant.Why then memcpy even let the source string be altered written onto Comment : @R ppell sVulture The documentation clearly says that it does not check for overlaps so you should not pass overlapping buffers so the const makes sense . Comment : @perreal Why aren t we warned or get an error that we are trying to change the value of a constant Comment : It s UB for source and dest to overlap . And the onus on you is to obey the contract and not pass overlapping objects . One of the goals of the C standard-library is to provide high performance code .

This dataset has a class imbalance situation and I want to know if there is also a problem of class overlapping . Each record has 30 attributes how can I discover if there is class overlapping using Weka features .. . Answer : To solve the class imbalance problem you can use SMOTE . It is in the Weka supervised filter instance . But can you explain what do you mean by class overlapping Comment : I used SMOTE to oversampling minority class and I had better results . Class Overlapping happens when some samples from different classes have very similar characteristics . So they lead to bad classification models . Comment : Does it have something to do with the degree of redundancy of features or correlations among features I am sorry I am not quite familiar with the term overlapping but just double-checking if it has any other synonyms .", "Question : I have two matrices . Each matrix is of dimension 3 k and represents k circles with each column in the form of x y r where x y is the center of the circle and r is it s radius . So one matrix which has 3 circles is in the form of x1 x2 x3 y1 y2 y3 r1 r2 r3 .. . .. . I need to find what are the circles which overlap and the overlapped area between the two matrices . Suppose consider a circle in first matrix . Now consider every other circle in second matrix . Now I need to find out what circles in the second matrix overlap with the circle considered . I need to do this for every circle in the first matrix . Similarly for every circle in the second matrix with respect to first matrix . So I need for each circle in the two matrices There are k1+k2 of them how much area is overlapping with the other matrix and what are the circles in the other matrix that are overlapping . .. . .. . Clearly there may be multiple circles which overlap.The dimension k may be different for two matrices . I have 2 extra matrices of each matrix one sorted by it s x coordinates and other sorted by y coordinates if that helps in computation.The problem is that there are a lot of circles in the matrix and i m looking for an efficient way to do it . Moreover I would like to extend this this more than two matrices and then an efficient algorithm would greatly improve the execution-time . A preview of the two images whose corresponding matrices of circles i have with me is given in the this link : https : www.dropbox.com s om5has5uw91dj6p overlap.jpg Comment : Think about what an inter-point distance-matrix would do for you . You can compute that matrix using bsxfun as an aid . TRY IT . Try something . You are more likely to get a useful response if you show some effort rather than just asking for someone to do it for you . Comment : Actually finding out whether two circles overlap is elementary however calculating the area of overlap requires some math . But once you formulate that formula in terms of the coordinates and radii then it will just be a matter of evaluation . However I don t know how it can be done in a complexity less than O k1 k2 . Comment : When you have lots of circles and relatively few overlaps you can sort on the X coordinate for example and only try to match when dx sum r . This can greatly reduce the number of comparisons needed . Alternatively you can sort on radius and for smaller circles divide the image into smaller boxes and only compare adjacent boxes . All these will in general reduce the number of comparisons - but matlab is pretty fast.. . what is the price of your time developing debugging more complex algorithms .. . Answer : You need two things : .. . .. . 1 . Find out what pairs of circles have overlap distance sum of radii .. . 2 . compute area of overlap for those pairs .. . .. . EDITED I modified the code to add some vectorization and trap the case where one circle is entirely inside the other - where the Wolfram formula http : mathworld.wolfram.com Circle-CircleIntersection.html was breaking down .

Does anyone have a solution Comment : Hmm seems doable at first but what is the rule if periods overlap only partially Like if the third period was until 2015-10-31 -- Ah got it now count actually gives the number of days in that range and is not an independent data column . Comment : Which RDBMS are you using Comment : Yes Column Count is a count of the number of days in de daterange . Tried to make it easier to explain my question . If ranges overlap partially it should count only the days of the part that is not overlapping Comment : Working with a MySQL database Comment : The end dates themselves do not count as part of the periods i.e . they are the first day after the period .. .

Answer : I would suggest using reasoning logic in combination with compiler messages and test results would be a better way to understand if a function has overlapping patterns or not . As two examples the first which has already been listed indeed results in a compiler warning . in the second case if we swap the last two lines around then a compiler error which states . Program error : pattern match failure : init1 results .. . .. . This matches the logic of passing a singleton list which could match in both patterns and in this case the now second line . will match in both cases . If we then move onto the second example .. . .. . In the second case if we again swap the last line with the first line then we don t get a compiler error but we also don t get the results we expect . Main drop 1 1 2 3 returns an empty list .. . .. . In summary I think this is why reasoning as oppose to a formal definition for determining overlapping patterns works ok ." ] }

Answer : This may be a simple question but what is the correct FiPy syntax to use if I want to solve PDE with spatially varying coefficient that is outside of gradient I think that the general equation can always be rewritten in such a way that FiPy can still operate implicitly on the solution variable . This does require an extra source term in most cases . I know this simple equation can be massaged so that I don t need to worry about spatially varying coefficient that is outside of gradient or simply move the coefficient inside the time derivative term but I ll have to add-in more terms for the actual problem I m trying to solve and the trick will no longer be valid .

Although there is an extra term the terms are still implicit in phi and the extra term can be represented as an implicit source term for phi depending on the sign of g f . FiPy should handle the sign issue just by using the ImplicitSourceTerm . Note that often r occurs outside of the operator when using cylindrical coordinates .

Answer : We have a large OSGi project with some own bundles and hundreds of third parties bundles . After some tweaking of dependencies we were able to produce a valid Launch Configuration that runs correctly and a product feature configuration that builds correctly via IDE of Eclipse Luna and generates a valid executable . So far so good with IDE PDE build . Now we want to run the build in the headless way .

But I don t want to commit 266MB of eclipse if I maybe need only 20MB of it . Thanks Christoph .. . Answer : I can t directly answer your question but I can wave my hands around a little bit some of which might help you find a real answer . In my PDE experience I have found it very useful to distinguish : .. . .. . The Eclipse IDE I was using for interactive editing .. . The Eclipse installation I was using for headless PDE builds .. . The target-platform set of plug-ins features etc . the thing I m building depends on .. . .. . It sounds like these are clear separate concepts in your head as well : you have already isolated the target-platform and are looking to isolate your interactive Eclipse from your PDE builder . You could try creating a new blank workspace in your interactive Eclipse just to be sure you re looking at it not at your target-platform opening the Plug-ins view right-clicking a promising-looking plug-in like org.eclipse.pde.build and choosing Open Dependencies . The Flat Layout might be a more useful way to view the results than the hierarchical though in my Eclipse I don t seem to be able to copy and paste this list . In my case this didn t mention anything in the JDT which makes me think that actually trying to build a Java-based plug-in would fail but hopefully that would provide another lead e.g . can t find org.eclipse.jdt or something . It seems like there ought to be a way to use the Software Updates mechanism Target Platform or Buckminster to just name one plug-in and have all the others fall into place . Maybe you could use the Target Platform select the plug-in you need hit the button to select required ones then somehow export a build that would effectively just collect all those plug-ins I confess that we just checked in an interactive Eclipse some time ago and use it as our PDE builder . We don t use it interactively and we do maintain a separate target-platform as well . Our PDE builder is clearly not minimal but could also perhaps stand to be so I hope you ll update this space with your discoveries . Comment : Hi Woody thanks for your answer . You are absolutly right about the three concepts...thats exactly what I was talking about too . I basically want to get rid of the interactive Eclipse related plugins . Your ideas sound good and I will give it a try tomorrow . I will post my findings here . I wonder if we are the only ones thinking about this problem Thanks Christoph Comment : Ok here are my first findings : org.eclipse.pde.build and dependencies are not enough to make a build . The build-process somehow stops without debugging output so I first have to find out what actually happens under the hood . Do you know of any command-line argument so that I can get more debugging output about the internals of the build-process e.g . -verbose or something If I find out what is missing I try to find the needed plugins step by step and will post it here . Thanks Christoph Comment : Christoph I m not sure . . . but when you run a command-line PDE build somewhere along the way you are firing up an OSGi runtime which as I understand it has something akin to an Eclipse Workspace where it can cache dependency information etc . and also - relevant here - place log files .

Its goal is not to create an entire project but the building Eclipse blocks from an existing project . This is also true for PDE support . Quoting its documentation https : maven.apache.org plugins maven-eclipse-plugin pde.html : .. . .. . Note that the scope of the maven-eclipse-plugin is to synchronise the Eclipse .project and .classpath files with the configuration found in the pom file . Once you have finished configuring the Eclipse plugin as below and once you have run the eclipse : eclipse goal you will be in a position to build your plugin code with the Eclipse IDE or the Eclipse headless PDE build . The Eclipse headless PDE build can be triggered from within Maven using the pde-maven-plugin . As such the configuration you have simply enables the creation of correct .project and .classpath files for an existing project nothing more . Once this configuration has been made and eclipse : eclipse goal was run you will need to follow these steps : .. . .. . Open Eclipse and import the existing project by going to File Import.. . Existing Projects into Workspace . Right-click the new project and select Configure Convert to Plugins Projects.. . . Confirm this choice . You will then be able to build your Eclipse plugin directly in the IDE .

Answer : This is called a common-table-expression and is a way of expressing a recursive-query in SQL : .. . .. . t n defines the name of the CTE as t with a single column named n . It s similar to an alias for a derived table : .. . .. . The recursion starts with the value 1 that s the values 1 part and then recursively adds one to it until the 99 is reached . So it generates the numbers from 1 to 99 . Then final query then sums up all those numbers . n is a column name not a variable and the assignment happens in the same way as any data-retrieval .

Can you help me understand what is the recursive term in the above example . I m not able to understand which part of the statement is causing a recursion . Comment : values 1 is the non-recursive part aka root . The select after the union-all is the recursive part because it references joins to the CTE named t", "Question : I ve always thought that With clause was working as a one-time execute statement which behaves as a normal table - you can do all SQL operations on it as you would on a regular table . But it turned out that in several databases Oracle Netezza Sybase Teradata the with clause is executed each time it is used . Instead of 2 identical numbers the query above returns 2 different numbers so it is executed for each of the selects . If I have a very complex query within a With clause and I use it 5 times in the rest of the query it would execute 5 times which seems very ineffective to me .

Answer : In the oracle world http : stackoverflow.com documentation oracle 3506 recursive-sub-query-factoring-using-the-with-clause-a-k-a-common-table-express t 201607281050362523834 as explained here http : www.morganslibrary.org reference with.html The WITH query name clause lets you assign a name to a subquery block . You can then reference the subquery block multiple places in the query by specifying the query name . Oracle optimizes the query by treating the query name as either an inline view or as a temporary table . You can specify this clause in any top-level SELECT statement and in most types of subqueries . The query name is visible to the main query and to all subsequent subqueries except the subquery that defines the query name itself . A WITH clause is most valuable when the result-of the WITH query is required more than one time in the body of the main query such as where one averaged value needs to be compared against two or three times . The point is to minimize the number of accesses to a table joined multiple times into a single query . Restrictions on Subquery Factoring : .. . .. . You cannot nest this clause . That is you cannot specify the subquery factoring clause within the subquery of another subquery factoring clause . However a query name defined in one subquery factoring clause can be used in the subquery of any subsequent subquery factoring clause . In a query with set operators the set operator subquery cannot contain the subquery factoring clause but the FROM subquery can contain the subquery factoring clause . In your case you have used a random function which will be treated differently by the optimizer which will treat it as an inline view rather than a materialized one . As @ibre5041 suggested use a EXPLAIN PLAN for different cases . Consider the case of a recursive CTE it is used internally everytime .", "Question : I have a CTE and query this one .. . .. .

Large non-trivial queries are typically dramatically easier to read later or by new eyes than subqueries and at least in the case of Postgres magically perform much better in many cases . For reasons I have yet to understand stackoverflow.com questions 33731068 http : stackoverflow.com questions 33731068 postgres-cte-vs-subquery-performance-difference-why as the opposite seems more likely . .. . Answer : The main advantage of the Common Table Expression http : msdn.microsoft.com en-us library ms190766.aspx when not using it for recursive queries http : msdn.microsoft.com en-us library ms186243.aspx is encapsulation instead of having to declare the sub-query in every place you wish to use it you are able to define it once but have multiple references to it . However this does not mean that it is executed only once as per previous iterations of this answer http : stackoverflow.com revisions 706983 3 thank you to all those that have commented . The query definitely has the potential to be executed multiple times if referenced multiple times the query optimizer ultimately makes the decision as to how the CTE should be interpreted . Comment : Think of a CTE as a temp table-variable does that mean CTE is stored in disk or in memory Comment : You cannot use the CTE or subquery in multiple queries by definition . I m pretty sure that the optimizer handles the subquery the same way it would handle the CTE evaluating the result set only once regardless of how many times it is used within the 1 query Comment : @AlexCuse : I think I ve clarified the context of the CTE enough but I added more to try and clarify more . Comment : This answer is very misleading . A CTE is not a temp table think of a CTE as a view that is defined only for your current query . Just like a view a CTE is expanded and folded into the overall query plan . Global optimization will still occur but do not think that just because you use a CTE you will only execute the query once . Here is a trivial example that fits in this space : WITH vw AS SELECT COUNT c FROM Person SELECT a.c b.c FROM vw a vw b The query plan will clearly show two scans aggregations and a join instead of just projecting the same result twice .

Answer : I have had the same requirement . Indexes can not be added to a CTE .

CTE and derived tables are very similar any query using derived tables can be rewriten as a CTE and any non-recursive CTE can be rewritten as a query using derived tables .

The CTE form might suggest that an intermediate result is created then the join is run on the intermediate result but this is not true .

About difference between temporary table and table-variable refer this question https : stackoverflow.com questions 27894 whats-the-difference-between-a-temp-table-and-table-variable-in-sql-server or msdn https : msdn.microsoft.com en-us library ms175010.aspx . CTE https : technet.microsoft.com en-us library ms190766 v sql.105 .aspx is like nested query temporary result set . Primary difference is that it can be self-referenced like in your case . You declare CTE with only one column number . Specifying columns manually is not required if they can be resolved . This is a recursive CTE https : technet.microsoft.com en-us library ms186243 v sql.105 .aspx - select a number and join itself appending +1 to number . So each subsequent row will have +1 to previous row . When you select from CTE anchor select @start number as number is executed . Than it concatenated with everything returned form itself with +1 added . Let s go step by step inside CTE : .. . .. . So your result set is each nest level is inside and : .. . .. . where 1 +1 2 1 1 +1 +1 1 2 +1 2 3 and so on .. . .. . So if you will not limit this query nesting will be infinite . That is why recursion limit appear . Engine will simply filter your infinite query and stop nesting as on any subsequent selection it will get value that will not match you filter and that selection will return empty result set . For example you filter values less then 10 : .. . .. . Note that if you filter incorrectly in recursive call e.g . that very first recursive call will return to you @start number which is not match to you filter and no recursion will occur . Actually filter .. . .. . is excessive . It can be simplified to .. . .. . Note in both cases filter will not match @end number as adds +1 to previous value . So as you start with @start number anchor and concatenating with with recursion that returns .. . .. . result will be .. . .. . Hint https : msdn.microsoft.com en-us library ms181714.aspx in select statement option maxrecursion 10000 https : msdn.microsoft.com en-us library ms175972.aspx overrides default maximum recursion level by default it is 100 valid values are 0..32767 . So your particular function is limited to 10000 values and if you will try to generate more then 10000 values you will get this error : .. . .. . The statement terminated . The maximum recursion 10000 has been exhausted before statement completion . Note filter that limits recursion must be placed inside your CTE not where you use that CTE as in that case engine will continue to iterate through CTE looking for next matching value but your CTE would be literally infinite and error will occur . Rest of code is pretty simple - result form CTE inserted into @numbers table-variable and then simply selected . Variable @max recursion can be removed as it not used and cannot be used inside OPTION clause .", "Question : I am using a Common Table Expression for paging : .. . .. .

The plugin does not seem to recognize linked virtual folders and hence does not add them as a source folder to my project . Is there a solution for this where I can add a linked folder as a source folder to my eclipse project generated using the Maven eclipse-plugin Thanks in advance . Comment : So to be clear does your source in version-control have a POM file and can be built with mvn clean install I was confused by your comment My eclipse work space is under C : eclipse workspace where I have the POM files . Comment : No the source from SCM is separate from the Mavenized project . So there is no POM under italic C : source italic it only has the source code . The POMs are located in the Mavenized project in the work space . Comment : Wow that feels a highly convoluted approach . Have you considered adding a POM to the source code and just running eclipse : eclipse there Some effort would be required to get the POM to accept the non-standard hierarchy but it should be doable . Then the invocation of eclipse : eclipse would be normal and you could just import the existing project into your Eclipse workspace using the menus . Comment : Hmm no the source cannot be mavenized at this point of time hence the search for a workaround . .. . Answer : Have you tried the following approach 1 . Check out source including existing POM file to C : source . 2 . Open Eclipse to workspace C : eclipse workspace . 3 . Select File Import.. . Maven Existing Maven Projects .. . .. . 4 . Navigate to the directory containing your pom.xml file and proceed to import . This works for me on projects where I keep the source and workspace paths completely separate . Comment : But when I import the project there is no source attached to it . Do I not need to manually configure the source folders then Comment : You shouldn t have to . Does your Maven project follow the standard project layout http : maven.apache.org guides introduction introduction-to-the-standard-directory-layout.html My answer also assumed you have an existing pom.xml file which builds fine from the command-line . Comment : No the source does not follow the standard layout either which is why I wanted to create virtual folders as per the standard layout . As an example the source module is like : source module java-package which when I import as a source folder would be like : module src main java java-package - where : virtual folder . It might not be possible at this moment to re-structure the source hence the problem . Comment : I guess this might be confusing but when I say eclipse-plugin I do not mean the m2e plugin for eclipse . I mean the maven-eclipse-plugin . Now to answer your question I have been running eclipse : clean eclipse : eclipse from the command-prompt and there I see the problem . The thing is when the plugin generates the .project file it correctly creates the virtual folders but in the generated .classpath file it does not have any references to the virtual folders as source .

Does this mean the maven-eclipse-plugin is essentially obsolete What can we do to help our projects import into Eclipse in the best possible way .. . Answer : From a methodology perspective I would really prefer the m2eclipse way -- i.e . Eclipse invoking maven for builds so it does exactly the same thing as a pure maven-build . The problem I found with the m2eclipse though was that it always got so horribly ridiculously go-have-a-coffee-break-while-you-wait-for-it slow performance when the maven project became larger adding more and more sub-projects . I first tried it in 2010 and finally gave up on it . Tried it again a year later and to my dismay it still sucked just as much -- I dont get it -- it takes MUCH MUCH longer than just building with mvn clean install directly -- shouldnt it actually do the same thing The mvn eclipse : eclipse-plugin on the other hand works like a charm as long as you just have a PURE java jar war build . But if the maven build does other plugin stuff for example legacy rmi-compiles or using ant for sub-tasks etc that will just be ignored during the Eclipse-build and so doesnt work . The workaround for that is that you FIRST need to build the project ONCE in maven then run mvn eclipse : eclipse then you can edit java-code and it works in Eclipse -- as long as you dont do Project Clean If you do you that or change anything in the maven-plugins parts Eclipse doesnt understand about you need to re-build in maven then do eclipse : eclipse again then refresh the project in Eclipse . Thats how I usually work and I think and it works good enough . Comment : Reading the documentation it looks like as eclipse : eclipse provides enough configuration options to add builders for ant and other tasks . Have you tried them out", "Question : I am new to maven and hit a problem that looks easy in the first place but I already kept me busy for a whole day about and no way to get it working .

Comment : Simply edit your post there you make better formatting . .. . Answer : It is a bad practice to include stuff from outside a artefact directly into a artefact . You should only include into project2 stuff below folder project2 and something from project2 s dependencies . I m not sure whether what you are doing is possible at all . So if you want to have project1 properties available in project2 you usually pack project1 properties in project1 s artefact and add a dependency on project1 to project2 . If this does not work for some reason for example since you want to move project1 s stuff to another location in project2 you can unpack it with maven-dependency-plugin http : maven.apache.org plugins maven-dependency-plugin dependency : copy-dependencies into project2 s target to some appropriate place .", "Question : I would like that the JAR build-path or jar files in the build-path of and eclipse project pointed to a local directory into eclipse project named lib not pointed to M2 REPO variable my maven local repository path .. . .. .

It s possible to uninstall just the maven support and keep the rest", "Question : I want to modify automatically the order on which classpathentry are written by the Maven Eclipse plugin . Is there a way to do that I want to do that for two reasons . First reason : in my application the interface org.w3c.dom.Node is provided by several third-party libraries for XML processing as well as the JDK 1.6 . However the version of org.w3c.dom . classes provided by these libraries are quite old compared to the JDK . For example the method Node.getTextContent http : download.oracle.com javase 6 docs api org w3c dom Node.html getTextContent 28 29 does not exist there . Running mvn eclipse : eclipse on my project will place these library before the JDK container in the .classpath using this method in Eclipse will result in a compilation error . So the idea is to put this line : .. . .. . at the beginning of the .classpath file . The second reason less important is when I run mvn eclipse : eclipse it always set my src test packages before src java ones which bothers me a little yes I know that in TDD we develop tests first but still.. . .. . .. . .. . .. . Technical information : Java 1.6 Maven 2.2.1 Eclipse plugin 2.8 .. . .. . .. . .. . Edit : There is a question here http : stackoverflow.com questions 793054 maven-classpath-order-issues that could look similar to mine but it did not help me as it only deals with the order for third-party dependencies.. . .. . Answer : See this post : Maven classpath order issues http : stackoverflow.com questions 793054 maven-classpath-order-issues . I can confirm that the 2.9 plugin has fixed this issue or allows you to futz with the config http : maven.apache.org plugins maven-eclipse-plugin myeclipse-mojo.html .", "Question : I have spent all day on the Maven site reading the 5- and 30-minute tutorials and trialing Maven out for the first time .

Comment : Try ticking your three jar dependency projects in Java Build Path - Order and Export . Comment : Nothing change with that .. . Answer : You could give a try to Eclipse Multi-project Import Export http : eclipse-tools.sourceforge.net projecttransfer . I think it will cover your needs . Comment : Nothing change with this plugin", "Question : With the maven-eclipse-plugin using mvn eclipse : eclipse http : maven.apache.org plugins maven-eclipse-plugin eclipse-mojo.html you can specifiy eclipse project natures http : maven.apache.org plugins maven-eclipse-plugin eclipse-mojo.html additionalProjectnatures and builders http : maven.apache.org plugins maven-eclipse-plugin eclipse-mojo.html additionalBuildcommands that will automatically be added to the eclipse project . Earlier versions of m2eclipse http : m2eclipse.sonatype.org used the configuration block of the maven-eclipse-plugin and also let you activate natures and builders using the same mechanisms . This seems to no longer be the case because a I can t find any reference to maven-eclipse-plugin in the m2eclipse sources and b it just doesn t work : - .. . .. . So this is my question : is there any way to configure the eclipse project generated by m2eclipse from the pom.xml Specifically : project builders and natures but I d be interested in other options as well . .. . Answer : Project configurators are the proposed approach . But the latest version of m2e-extensions is from early 2010 and developed against m2eclipse 0.10.x . There is a successor project called m2e-code-quality which is more recent and active and developed against m2eclipse 0.12.x . But neither m2e-extensions nor m2e-code-quality do support FindBugs at the moment . And there are some other limitations with header-files exclusions and modified JARs http : enterprise-it-solutions.blogspot.com 2011 02 m2e-extensions-project-configurator-pmd.html . I have successfully used a universal approach with AntRun Ant and XMLTask http : enterprise-it-solutions.blogspot.com 2011 03 settings-eclipse-project-antrun-maven.html to automatically add project natures builders and configuration-files for Eclipse plugins from pom.xml . Comment : Thanks for your feedback +1", "Question : Note : I didn t get any response in the first version of this question so I modified it to be more generic.. . .. . .. . Context .. . .. . My project is divided into several maven modules and several web-applications . Here is the structure : .. . .. . All the web-applications share common resources such as JS CSS and images files . Instead of duplicating these resources in each web-app-X I decided to create another project called web-resources which is a WAR project . The structure is then the following one : .. . .. . .. . .. . Maven .. . .. . In Maven 2 or Maven 3 as I just migrated my project to maven 3.0.2 this configuration is easy to manage as all web-app-X declare web-resources as a dependency : .. . .. . So when I build my WAR project it first get the web-resources.war built just before unzip it and build on top of it the web-app-X web-application . This way my WAR file will contains also a directory called web-resources that contains the shared resources . This is the war overlay principle . So on a Maven point of view everything is fine .. . .. . Eclipse .. . .. . Now here comes the main problem : having a good Eclipse configuration . Question : How can I use my current configuration to be managed correctly by Eclipse In particular when I deploy any web-app-X in Tomcat using Eclipse.. . Note that I want to get the more automatizable configuration and avoid any manual steps as this configuration should be used by dozens of developers.. . .. . .. . For me the best solution seems to use the linked resources of Eclipse . Thus I set the following configuration in my web-app-X pom.xml : .. . .. . When I run the mvn eclipse : eclipse configuration it adds succesfully this information in my .project file : .. . .. . Now I import my project in Eclipse . Problem : in Project properties Java Build Path Source I don t see the Link Source present . I only see my four Maven default directories src main java src main resources src test java and src test resources . What is strange is that when I try to manually add the linked resources it refuses and says that it already exists.. . So when I deploy my web application on my Tomcat in Eclipse it does not deploy the web resources directory and thus I don t get the CSS JS images deployed . After some tests it seems that I have to do two modifications : .. . .. . 1 . Add the line classpathentry kind src path web resources output src main webapp web resources in my .classpath file .. . 2 . Remove the project preclosing-web-resources project in the .project file . Note that using this configuration Eclipse will copy and keep synchronization the content of web resources project in my web-app-X src main webapp web resources but this is not a problem this directory is ignored by the SCM . The only automated solution I found was to create a simple Maven plugin that do the two previous modification and then run the following command or use a .bat file : .. . .. . .. . .. . Question .. . .. . Is there a better way to manage such configuration .. . .. . Technical information .. . .. . Java 6 Maven 3.0.2 maven-eclipse-plugin 2.8 Eclipse 3.3.2 but I can test with newer version of Eclipse no m2eclipse plugin . .. . Answer : You might want to take a look at this blog post . It covers a method for sharing resources using maven : .. . .. . http : www.sonatype.com people 2008 04 how-to-share-resources-across-projects-in-maven", "Question : I have spent all day on the Maven site reading the 5- and 30-minute tutorials and trialing Maven out for the first time .

Comment : I liked this option as it will automatically List out the compatible m2e version for the eclipse we are using.Earlier I was trying to get the latest m2e plug-in for juno..but it was giving exception while installing" ] }

Answer : Imagine that your TreeModel uses an independent real tree and some nodes are inserted by separate process which is not aware of the model existing . Or two TreeModels use the same tree of objects nodes . The process just adds children to some nodes . Or you insert node in the first model but also have to update the second . Then you somehow should update model . In this case you use nodesWereInserted and you need public-method to be called from outside the model .

In order to do this I expected to be able to do Kryo.register DefaultTreeModel .class and send then when I need to update the JTree all I would have to do would be server.sendToAllTCP this.treeModel but when I attempt to do that Kryonet gives a series of errors requesting that I register all the classes used by TreeModel . However registering all the required classes then results in some internal error with Kryonet . My question is this : what is the best way to send a TreeModel to a client Or is there even a way to do this The other option for me is to extract all the individual objects in the JTree and send them separately which is inefficient and time consuming .", "Question : I have an application which contains a JTree backed with a DefaultTreeModel that is used to display a hierarchy of files which reflects a section of the file system on my server I will refer to this as my client app . I also have a server application which provides the data that my client app needs to display I will refer to this as my server app . I am using a lazily load children approach so that I only have to load files into my tree if the user is interested in them . Lazy load approach : .. . .. . 1 . I override treeWillExpand TreeExpansionEvent evt .. . 2 . I set the selection path to be that of the expanding node . 3 . Then I send a message to the server asking for the children of that node . 4 . When the server responds I get the last selected path component . 5 . Then I use DefaultTreeModel.insertNodeInto for each the returned data files . 6 . Finally I call DefaultTreeModel.nodeStructureChanged .

My problem comes when new data is uploaded to the server and I want to update the tree to not only include the new data but also to set the expansion state and selected node to what it was prior to updating the tree so that the user is not jerked around on the tree just because there is new data to view . The flow is as follows : .. . .. . 1 . New data is uploaded to the server .. . 2 . Server app archives this data and populates a database with information about the uploaded files . 3 . Server app notifies client app that new data was uploaded . 4 . Client app saves the expansion state of the tree using JTree.getExpandedDescendants .. . 5 . Client app saves the selection path of the tree using JTree.getSelectionPath .. . 6 . Client app removes all nodes from the DefaultTreeModel . 7 . Client app requests data from the server starting with the root node . 8 . Client app traverses the tree path enumeration returned from JTree.getExpandedDescendants calling JTree.expandPath on each TreePath in the enumeration . 9 . Client app sets the selected tree path . My problem is that no matter what I try the tree s GUI is not updated to reflect the expansion state . I know that my call to expandPath is working because I can see the request for data sent from the client and the response with data from the server for each call to expandPath . I also display information about the currently selected node in another window and it is showing the correctly selected node . But alas to my disappointment the GUI only displays the root node expanded and it s children not expanded instead of the previous expanded state .

Answer : We can have our own custom tree node which is doing some processing . Say we want to check if the new node is eligible for being inserted . We add a new child to this custom tree node with the DefaultMutableTreeNode.insert method . At this point we need to inform the model about the insertion by calling the DefaultTreeModel.nodesWereInserted method . If the modifications are too complex it might be necessary to call the DefaultTreeModel.reload method . If we do not have any custom processing in a our own tree node then we can just add a new node by calling DefaultTreeModel.insertNodeInto . Comment : it might be necessary to call the DefaultTreeModel.reload not to use proper models notifiers but depends of structure because is possible to create an ZOO", "Question : null .. . Answer : I am working on a swing based application that uses a JTable with a DefaultTreeModel and a lot of models on top of it . We optimize our models to improve the performance but we hit a problem from java core . Every time a node is inserted in the table the resetRowSelection method is called .

This causes the tree not being garbage collected if the model is referenced from somewhere else . Example : I implemented a TreeModel using a WatchService http : openjdk.java.net projects nio javadoc java nio file WatchService.html to have an always up to-date model of a file system tree . Even a single listener on the model requires me to keep the WatchService informing the model about file system changes so it cannot be garbage collected . So even if the JTree is not visible anymore it is still kept in memory by the model which still needs to get updates from the WatchService although none of this is necessary any longer . I guess the best way would be to create a new class extending JTree that does the registering to and unregistering from the model .

I think the second problem is caused by the first . Comment : I don t know I see distinct questions but that s me.. . Comment : OK I just changed it to focus on a single problem . Comment : There seems to be a disconnection between where you want to insert the new node and where the model thinks it resides this is caused by the fact that rather than actually modelling the file system you are continuously reading from it . .. . Answer : There seems to be a basic mismatch of approaches . You are using DefaultMutableTreeNode s which cache there child nodes but are managing the actual nodes directly via the model this is causing confusion at multiple different levels.. . If you want to continue monitoring the disk contents directly or proxying it I would create a custom TreeNode whose sole responsibility was to monitor a single directory . I would then create a custom TreeModel probably from the DefaultTreeModel which provided a makeDirectory method which you would pass the currently selected TreeNode and the name of the directory . This method would then be responsible for the physical creation of the directory and notification of the structural changes to the JTree via the nodesWereInserted method . I d probably have this node return an instance a TreeNode which represented the child.. . There are a lot of problems with this approach namly with the referencing of objects . In your current approach you are creating a new DefaultMutableTreeNode whenever getChild is called this could cause issues if parts of the API are relying on those references remaining constant for the given position data this would require you to maintain some kind of internal cache linking the File with the TreeNode ...which kind of defeats the purpose.. . .. . .. . A better approach might be to utilising the existing mutable tree node API each node would still be responsible for a single File but it would also cache the results . The problem here is managing when a node should be populated as you don t want to populate directory nodes that are not expanded . I you are planning on utilising the Watch Service API then I would go for the mutable tree node API and cache the child files within it as you need to it will simply the issues.. .

Answer : So the trick is to use a single TreeModel link the tree s SelectionModel s and two custom TreeCellRenderer s and use a TreeExpansionListener capable of determine which tree expanded collapsed and mirror the results . Basically each tree shares the same TreeModel and SelectionModel this makes life so much simpler as they will both respond to changes that are made to both models . Expansion collapse is a little more difficult as this needs to be handled via a custom TreeExpansionListener which is detects who triggered the event and then notifies the opposite tree of the change . Next I use a common data object with this contains basic information about the data that should be shown by the tree s.. .

Multiple assigns of the Model result as you have seen in applying only the last one .", "Question : How can I create a JTree using data from a .txt file The text file is formatted as follows : .. . .. . The .txt file contains over 700 lines . Comment : What you have tried Comment : @Abhishekkumar well I know how to hard code the JTree by adding nodes one by one but that is bad programming practice - programming to implementation as opposed to programming to an interface . So I wanted a smarter way and I came to StackOverflow where I have learnt that it is not a place where someone just does all the hard work for you . You have challenged me to think harder and research widely which led me to the solution . Thank you . .. . Answer : If the txt will have tabular or spaces well formatted you can read the file line by line count the number of spaces and then add the node to the tree as needed . You can read more about JTree in java tutorial How to Use Trees http : docs.oracle.com javase tutorial uiswing components tree.html . But as @Abhishekkumar said what have you tried Why you can t do it Complete your answer and don t make others do your work . Comment : Thanks . I actually knew what to do in theory but I didn t know the implementation details . I couldn t find a concrete example online and I guess I was just being too lazy to think and come up with the implementation .", "Question : How can I create a JTree using data from a .txt file The text file is formatted as follows : .. . .. .

Answer : Just as PhoenixS http : stackoverflow.com users 491245 phoneixs has mentioned in his answer above the procedure involves the following steps : .. . .. . 1 . Read the .txt file line by line . In this example we use BufferedReader http : docs.oracle.com javase 6 docs api java-io BufferedReader.html in conjunction with InputStreamReader http : docs.oracle.com javase 1.4.2 docs api java-io InputStreamReader.html OR FileReader http : docs.oracle.com javase 1.4.2 docs api java-io FileReader.html depending on whether we are reading the .txt file as a resource or from the File System respectively . 2 . Depending on the formatting of the .txt file use the delimiter to determine the hierarchy level of each line as it is being read . Use this to create the relevant nodes of your Jtree . In this case the .txt file is tab-delimited with the number of tabs indicating the hierarchy level . Here is the TreeFromTextFile class I wrote : .. . .. . To test the above I wrote the TreeFromTextFileDemo class which is as shown below : .. . .. . .. . .. . The following screenshot illustrates the output .

From the docs at https : github.com neovim neovim wiki Troubleshooting python-support-isnt-working .. . .. . You get errors could be that you have your VIM environment variable pointed to the wrong probably vim74 runtime directory . Neovim needs pythonx.vim from the runtime autoload providers folder to load a python interp . Vim74 doesn t provide this file . If you have an env . variable of VIM with a path it will use that as your location of your runtime files - I had my set to usr share vim vim74 changing it to the location of neovim worked .

These greatly improve windows navigation in Vim . However I ve noticed that C-h does not work as expected when executed in terminal buffer . Trying this on a usual terminal session results in Backspace action . So probably it seems to be one of these alternative key combinations like C-i for Tab or C- for Esc . But is there any way to make C-h work in Neovim s terminal session as per my bindings Thanks .. . Answer : This issue has already been extensively debated here https : github.com neovim neovim issues 2048 . Original Vim does not rely on terminfo and includes its own patch for correct handling of C-h sequences . Neovim does look at terminfo though . Briefly the fix is executing these commands in the shell :", "Question : Now that we have terminal mode in neovim I am wondering if there is still a use-case for tmux . Let s say that I need to work on a remote machine using SSH . In order to keep a persistent vim session I would launch a tmux session on the remote machine start neovim and create as many terminal windows as needed . I don t need to use the windowing mechanism of tmux anymore . Are there any use cases that neovim terminal mode cannot satisfy .. . Answer : tmux provides session management . For example you can create multiple sessions and then detach re-attach as you please . With terminal emulation in neovim the shell is killed when the terminal buffer is closed . So there s still a use-case for it however the primary use-case with regards to vim + tmux has been eliminated with terminal emulation .", "Question : null .. .

Comment : So you are on right track just report the issues to plugin maintainers .", "Question : I am working on a Neovim plugin that interacts with a REPL in a terminal buffer . I want to be able to send a command to the REPL copy the response and display it to the user somehow . Currently the terminal buffer doesn t seem to refresh output until the current vimscript function terminates so I can t have a single function that does eg : .. . .. . as the get response function is working with the terminal buffer before it gets updated . Currently I m using neovim s job control though if this can be accomplished in vanilla vim all the better . Here s the code I m using to initialize the terminal : .. . .. . Here s how I m sending the command to the REPL : .. . .. . I ve tried adding an edit command to refresh but that doesn t seem to work in the REPL . The code for communicating with the REPL is here https : github.com parsonsmatt intero-neovim blob master autoload intero repl.vim . The code for managing the process is here https : github.com parsonsmatt intero-neovim blob master autoload intero process.vim . .. . Answer : In the : term buffer you can set up a TextChanged handler . E.g . the following code sends the entire : term buffer contents to s : on response : .. . .. . Figuring out which text is new since the previous TextChanged event will require some custom logic . The and marks aren t correctly set in the : term buffer I m not sure this is feasible for nvim to do automatically but I made a bug report https : github.com neovim neovim issues 5017 . Note that TextChanged only fires if the user is in normal-mode also immediately upon leaving insert-mode . TextChangedI notice the I at the end should fire in insert-mode but it doesn t work with : term that s a bug https : github.com neovim neovim issues 5018 . .. . .. . Another approach is to user timers see : help timer start . Here s a timer that calls s : on reponse timer id every second : .. . .. . But this isn t ideal because you would need to keep a map of terminals and timer ids or iterate through all : terminal buffers and check their contents . .. . .. . I made a feature request https : github.com neovim neovim issues 5023 for a jobattach function which would allow attaching on stdout handlers to existing jobs whereas jobstart only adds handlers to new jobs . This could then be used to attach to b : terminal job id of any : term buffer . Comment : Hmm the TextChanged autocmd doesn t quite do what I expect . It appears that it only fired when the user s cursor is currently located in the terminal buffer . Checking out jobattach now Comment : jobattach doesn t exist yet--it would be a feature request . Comment : @ephrion I added another suggestion using timers . But probably jobattach is what is really needed . Comment : @ephiron In github.com neovim neovim issues 5023 https : github.com neovim neovim issues 5023 bfredl noted that you could use termopen to attach an on stdout handler just like you would with a normal jobstart . So that should help as long as your plugin is in control of creating the : term buffers .

Created a jar called apache-mime4j-0.8.0-fix.jar and pushed into the lib folder .. . 6 . I use run.sh so replaced the mime4j core jar name with the above one . I am sure there is some mismatch between spooler and mime4j . I think the calling code should use the Builder instead of directly trying to instantiate the MimeConfig .

However I haven t managed to find out how to connect to a mail-server to then use mime4j to parse messages . Javamail provides session and connections to a mail-server via IMAP or POP3 from which you then read Messages . As far as I can tell mime4j does not offer anything equivalent . So how can I connect to mail servers to use mime4j Can I use Javamail in conjunction with mime4j I have tried using the javamail Message.getInputStream method to get an input stream that I pass to mime4j s DefaultMessageBuilder.parseMessage . However the result is not what I expect : for a multipart message containing a plain text part and an html part only one TextBody is created . I suspect this is because the DefaultMessageBuilder.parseMessage is expecting a stream for the whole message not just the body but that javamail Message.getInputStream only provides the body . In fact I m only interested in the body since this is what was causing problems with Javamail but parsing the whole message if I could get it as an input stream form Javamail would do just as well . Any help greatly appreciated .. . Answer : If you re using POP3 all the message parsing happens on the client-side in JavaMail . Have you looked at the many properties you can set in JavaMail to configure how parsing errors are handled If you re using IMAP most of the parsing is done by the server . What sort of parsing errors are you still having with JavaMail Are they problems parsing the content of the email messages or problems parsing the IMAP protocol messages With more details of the problems you re running into I might be able to help you configure JavaMail to work for you . If you really want to use another MIME message parser you ll need to use the Message.writeTo method to get the entire MIME content of a message which you can pass to some other library to parse . Comment : I ve been using IMAP but experiencing hanging when using methods on the Body using Javamail rather than errors . I tried various suggested methods to force parsing on the client-side like making a copy of the Message but none worked . Perhaps just using POP3 would work better . Just tried the Message.writeTo and it works . I tried it before but must have misinterpreted the results . Thanks Comment : Hangs usually mean your server is broken . Again I m glad to help you make JavaMail work but I need a lot more details of the problems you re having . Feel free to send me the details at javamail ww@oracle.com if you don t want to deal with it here . Comment : Thanks for your offer of help Bill .

Comment : MIME parsing is not easy because the grammar is not very well defined . The problem is that I m under the impression that it has been built block by block . Thus you the informations are very sparse and there is not a one-standard format . I read the RFCs multiple times and writing a compliant MIME parser is not an easy task because of this problem . As a semester project I started to implement a MIME parser to show how you can interleave multiple parsers with a MIME parser when you have a multipart message . It s really an early implementation and does not follow the RFCs because I only focused. . Comment : on the interleaved part . Nevertheless you can maybe tweak complete the current implementation I started very incomplete github.com alexcrt interleaved-parsers blob master src main https : github.com alexcrt interleaved-parsers blob master src main scala mime MIMEParser.scala . I used the parser-combinators API . If you have a clear well defined grammar for your input then it shouldn t be very hard to complete this code to parse the email messages . However you may want to look at other libraires for MIME parsing . If you re not limited to Scala you may try Flanker github.com mailgun flanker https : github.com mailgun flanker which can parse MIME messages .

I am attempting to read a given message event as defined by the START MESSAGE and END MESSAGE headers as an entire event as I will be moving the process to a distributed filesystem eventually and need to plan for file-split boundary traversing . For the event-based parsing in mime4j a ContentHandler interface is required and methods are called from it by the parser which requires the handler be set to it .

Answer : A simple way is use to the lfe command to run LFE scripts . The lfe behaves in similar fashion to bash in that you can use it to run scripts . The lfec script defined in bin lfec is a good example of this . It is an LFE shell script which parses it arguments and run the LFE compiler . Comment : 1+ Yes bin lfec is an interesting example of using lfe comp : file 2 that if I m not wrong compiles the script behind scenes . LFE is great as Lisp environment that targets Erlang VM but I think that exposing itself using CaaS compiler as as service pattern is a very cool thing . Comment : @gsscoder almost lfe comp : file 2 compiles the file which is the argument to lfec the script itself is interpreted .

Answer : I won t attempt to answer completely your broader question about the best practices of adding scripting . It seems to me that choosing between hook-based solution in which you define hook implementations by name convention and they are automatically recognized and explicit api solution in which you use functions predefinied in the scripting enviroment to register your hooks or otherwise call configuration functions is largely a matter of taste . Explicit calls like set-connection-timeout-handler .. . may be more readable easier to debug no misspelling problems no surprises on api changes easier to document and a bit more flexible but more well explicit . Building from your simple variable definition example here are a few ways you could get started going further the interpreted path : Comment : +1 This answers my question and puts me in the right path . Before getting this reply I was reasoning about the two scripting patterns you quoted ending that probably the best solution could be return a data structure from LFE like a tuple . You explain this and a lot more.. . The reply really helped me . It would be great to have this explained in LFE docs or also in a blog post .

Answer : My apologies I know this post is basically dead but I don t find other posts on the topic thus replying here seems appropriate . I believe I ve found a methodology that works .

And then you know it mumbles something about having added up some numbers and the answer being 7 . .. . Answer : There is a serious lack of examples in the LFE release all contributions are welcome . Christian s suggestion is correct . My only comment is that there is no need to have capitalized variable names it is not wrong but not necessary . The LFE let is a real let in which the variable bindings are visible first in the body . You can use patterns in let . There is also a let form macro actually which binds sequentially . No I have so far kept all the Erlang core function names just as they are in vanilla erlang . It is definitely more lispy to use - instead of in names but what do you do with all the other function names and atoms in OTP One suggestion is to automatically map - in LFE symbols to in the resultant atoms and back again going the other way of course . This would probably work but would it lead to confusion I could then have a behaviour module looking like : .. . .. . But I am very ambivalent about it . Comment : It would probably lead to confusion . Imagine all the time that has been spent informing users of Common Lisp that atom names are not case insensitive but that the reader is just uppercasing atoms before interning them . Comment : My small experience is that the syntactic mapping between lisp and erlang disappears very quickly from view which means that a coder will read erlang source and mentally translate it by substituting parentheses for commas etc . I think another step of rewriting identifiers would trip me up almost every time as I would only be looking to rewrite syntax .

I copied the lfe shell script as a batch-file replacing @ with 1 2 3 4 and it gives me this : .. . Answer : The problem here is that Erlang can t find the LFE ebin directory . Two ways to solve this problem are : .. . .. . Use an explicit -pa lfe ebin dir argument when starting LFE either in the lfe.bat script or when you call it . Simple but hard wired . Use the ERL LIBS environment variable . This is described in the code module documentation http : erlang.org doc man code.html . If you create an extra Erlang library directory say c : projects erlang drop Erlang apps which follow the Erlang application directory structure as LFE does and point ERL LIBS at it then the code server will automatically add ebin directories it finds there to its code path . This is also described in How do I install LFE on Ubuntu Karmic http : stackoverflow.com questions 2835942 how-do-i-install-lfe-on-ubuntu-karmic but in a UNIX context . The ERL LIBS feature should definitely be better advertised . EDIT : Replying to @Shantanu Kumar s comment . I don t have access to a Windows machine so I can t test it properly . The problem seems to be that using lfe boot tries to start the port program ttysl which doesn t seem to work on Windows at least not when running erl.exe . Some solutions to try : .. . .. .

Is there an example how I would create a hello world source file and compile and run it .. . Answer : No there is nothing you missed . The Makefile in LFE is less than perfect and should be ignored it will be improved upon in the next release . To compensate all the needed files have already compiled and the .beam files are in the ebin directory . As it is not part of OTP I don t think it should ever install there . The easiest way to handle this to create a private erlang library directory and point the environment variable ERL LIBS to it . Then just drop the whole LFE directory there . When erlang starts the code server will automatically add the lfe ebin directories into the path and the .beam files there will automagically be found and loaded . This will work with any package that contains an ebin directory . This also works on Windows . So : .. . .. . 1 . Make an libs directory say erlang lib .. . 2 . Set the environment variable ERL LIBS export ERL LIBS erlang lib .. . 3 . Put the whole LFE directory there .. . .. .

I know about the pseries object from the plm package which can handle panel regression with lags .

Answer : There is no direct way to do lags in felm as of now but it is possible to do it as follows : .. . .. . The reason the lag does not work straight away with felm is that it will use the default lag function not the pseries lag . When specifying it as above the pseries lag is used .

This will incur a copy of the entire dataset but is no different from what plm does behind the scene . Comment : The next release of lfe in a month or so will support this directly with pseries provided plm is loaded . It turned out to be a very simple fix . At a single point when I create the model frame I have replaced an as.formula with an as.Formula . The class of wage is then preserved and the right lag will be used . Comment : The current version of lfe 2.3 handles this i.e . felm emp output+capital + lag wage 1 firm data Em will use the pseries lag .", "Question : I am using the lfe package in R to do some regression with lots of fixed effects so direct lm is out of the question and since the fixed effects are not individual-level so is plm . I get the output with no problems but now I d like to use it in a LaTeX table . However none of the packages I tried like xtable apsrtable the latex command in Hmisc and so on have methods for objects of class felm . So my question is what do I do Is there a way to access the lm.method and twist it so it can read felm objects Is there a way to coerce felm objects into lm form Any ideas .. . Answer : As the author of the lfe-package I can shed some light on this . It is true that the felm-object mimics the lm-object but with some differences . It does not contain a copy of the data-matrix . The lfe-package is intended for very large datasets in the gigabyte-class . Thus some effort has been made to conserve memory . Another difference is that the felm-object does not contain information about the rank of the system in the same manner as lm nor the qr-decomposition used by lm . felm does not use a qr-decomposition and the rank can be a somewhat complicated matter . The upshot of this is that some standard methods will work on felm-objects whereas others will not . An early version of lfe actually had lm as an inherited class for felm but since this creates the impression that it actually is an lm-object I removed it .", "Question : null .. .

Answer : This might not be the answer that you are looking for but it seems that the author did not add any functionality to the lfe package in order to make predictions on external data by using the fitted felm model . The primary focus seems to be on the analysis of the group fixed effects . However it s interesting to note that in the documentation of the package the following is mentioned : .. . .. . The object has some resemblance to an lm object and some postprocessing methods designed for lm may happen to work . It may however be necessary to coerce the object to succeed with this . Hence it might be possible to coerce the felm object to an lm object in order to obtain some additional lm functionality if all the required info is present in the object to perform the necessary computations . The lfe package is intended to be run on very large datasets and effort was made to conserve memory : As a direct result-of this the felm object does not use contain a qr decomposition as opposed to the lm object . Unfortunately the lm predict procedure relies on this information in order to compute the predictions . Hence coercing the felm object and executing the predict method will fail : .. . .. . If you really must use this package to perform the predictions then you could maybe write your own simplified version of this functionality by using the information that you have available in the felm object . For example the OLS regression co fficients are available via model2 coefficients . Comment : Helpful comments .

Answer : As a workaround you could combine felm getfe and demeanlist as follows : .. . .. . The idea is that you use demeanlist to center the variables then lm to estimate the coefficient on Sepal.Width using the centered variables giving you an lm object over which you can run predict .

Does anyone know why they differ in their calculation of the SE s .. . Answer : The difference is in the degrees-of-freedom adjustment . This is the usual first guess when looking for differences in supposedly similar standard errors see e.g . Different Robust Standard Errors of Logit Regression in Stata and R http : stackoverflow.com questions 27367974 .

The non-robust standard errors also agree . And when comparing the clustered standard errors we can now show that felm uses the degrees-of-freedom correction while plm does not : Comment : Examining multiwayvcov : : cluster.vcov it is easy to see the algebra used to obtain the Stata small-sample degrees-of-freedom correction namely : df M df M - 1 df N - 1 df N - df K . But what would be the equivalent df correction as used is sandwich .. . adjust TRUE In this answer http : stackoverflow.com questions 27367974 you explain that the difference between the two is that for Stata the division is by 1 n - 1 and for sandwich it is by 1 n - k . Yet I m unsure how this translates into appropriate algebra.. . Do I replace df N - 1 by df N - df K above Comment : I think so but haven t checked the code in detail . Also note that currently sandwich itself does not offer clustered standard errors at the moment . All theoretical details behind the sandwich package are also documented in the two vignettes .", "Question : I am using the lfe package in R to do some regression with lots of fixed effects so direct lm is out of the question and since the fixed effects are not individual-level so is plm .

Determining whether creation of such a chimera is not doing violence to important underlying assumptions is your responsibility : .. . .. . Before doing that class engraftment I did look at the felm-object to see if it resembled an lm-object and it did . It also appears that summary est returns the output that would be expected by a user of lm . This does not actually do what you asked . The only thing it does is allow lm-targetted functions to attempt to do their work .

Answer : While saving an item in Page Editor Sitecore saves all the field renderers which are displayed on the page so if you set the Item property of a FieldRenderer1 to Product Example Test Sitecore Item Page Editor know which item should be saved . The problem with publishing is that you enqueue the current item in the publishing queue but this item has no link-to the Product Example Test Sitecore Item in any of its properties cause you re setting the Item property of the field renderer dynamically in the code . The option would be to add another button to Page Editor next to Edit Related Item button and create a command that will Publish Related Item .

For point 4 if we can type Mandarin or Japanese any reason why we need automated translator Comment : Also regrading translator did you say they use the Google translator API Comment : If your content authors type Mandarin and Japanese content manually you don t need any automated translator . In terms of automated translators there is a module called Sitecore Language Translator which uses Google API to translate the content but it will never be a proper translation . There are also paid solutions like Clay Tablet - your content is translated by proper human translators .", "Question : We use Sitecore CMS for our website at the moment and are considering adding the Sitecore DMS in the near future . A colleague of mine insists that it is absolutely necessary to have our page-editor along with the cloning functionality enabled and working for us to be able to use the DMS . I m familiar with their CMS but not the DMS so I wanted to know -- is it absolutely necessary .. . Answer : Cloning functionality is mostly used for Multivariant MV Tests . As it suggests in the Marketing Operations Cookbook http : sdn.sitecore.net upload sitecore6 65 marketing operations cookbook sc65-usletter.pdf : .. . .. . When you use the Page Editor to set up an MV test you can use existing content clone content or create new content items to use as test variable variations . This means that you do not need to ask a developer to help you to create special content to use in your MV tests . In the Page Editor one can create combination tests . These tests allow you to test more than one control on the same page . This is multivariant testing . More information on MV Tests like cloning items to use as test variables or creating combination tests is also given in the Marketing Operations Cookbook http : sdn.sitecore.net upload sitecore6 65 marketing operations cookbook sc65-usletter.pdf . More over also remember that you can also create MV Test in Content Editor but note the below as suggested by Sitecore .. . .. . If you create an MV test using the Content Editor you do not have access to the same statistics on Engagement Values generated when you test these controls . We recommend that if possible you create all MV tests using the Page Editor . So if one your goals for using Sitecore DMS is MV tests I would suggest you do use cloning .

Any thoughts welcome.. . .. . .. . Erwin .. . Answer : The problem you describe is not new to Sitecore 7 . You would have the same problem in Sitecore 6 you would just have to go through the additional effort of keeping your content organized . This is a fundamental limitation of Sitecore s presentation framework . I have worked around similar problems before by using Presentation Inversion of Control http : www.awareweb.com awareblog inversioncontrol1 category e697cc2030034ea39ef65be033a5c530 topic bcab6d57624347eda723110cd70bb48d . I should probably write an update for that since the rules engine approach no longer works .. . .. . I believe that Cognifide is doing something similar with the Composites in their Zen Garden http : www.sitecore.net Community Best-Practice-Blogs Przemyslaw-Taront Posts 2012 08 The-Zen-of-Sitecore-Part-1.aspx but instead of using a dummy layout they use an empty layout so any item can be opened as a page . Then they added a custom experience button which navigates to that non-page content item within the page-editor . Note that this is speculation based on a brief demo that I saw . Thomas Eldblom also blogged years ago about what he called Composite Layouts http : pentialized.dk tag composite-layout . It s similar to PIoC but puts the presentation settings on a special rendering type . In short there are ways to achieve what you want but they all involve custom development and will require extra attention to maintain a smooth page-editor experience .", "Question : I m in the page-editor and I m seeing JSON where editor controls should be .. . .. . commands : click : chrome : field : editcontrol command : webedit : chooseimage header : Choose Image icon : icon SoftwareV2 16x16 photo landscape.png.aspx isDivider : false tooltip : Choose an image type : null click : chrome : field : editcontrol command : webedit : editimage header : Properties icon : icon SoftwareV2 16x16 palette preferences.png.aspx isDivider : false tooltip : Modify image appearance type : null click : chrome : common : edititem command : webedit : open header : Edit the related item icon : temp IconCache SoftwareV2 16x16 cubes blue.png isDivider : false tooltip : Edit this item in the Content Editor . type : common contextItemUri : sitecore : master 2D90E98C-1360-4EBA-855E-3B321B053376 lang en ver 1 custom : displayName : Logo expandedDisplayName : null .. . .. .

The error occurs when I am in the Sitecore Page Editor mode . First of all I m not able to select each of the content items on the page and I m not really sure why that is the case . But I may not be 100 clear on what the requirements are for configuring a content item for an A B test in Sitecore . In the Sitecore Page Editor when I highlight a content item and click the red boxes icon to bring up the Test the Component dialog the Test Content Item : just says Not set . When I then click the 3 dots to attempt to browse to a content item I get a pop-up error message that simply says an error occurred . What are the requirements for a content item to be defined as a test variation in this version of Sitecore Or is there something else that needs to be done before attempting to configure the test variations in the Sitecore Page Editor Comment : Just to check is the component you are testing driven by a datasource Comment : Currently no and that is one of the things that I wasn t sure about whether or not it was a requirement for this to work . In addition to having a datasource it seems like the content item that you are defining the test variations for needs to be a sublayout that is attached to a placeholder . Is that correct .. . Answer : In order to use A B Multivariate testing your Sitecore website solution needs to support the idea of page components . Each component is a sublayout that pulls its content from a datasource item . The test is essentially just swapping the datasource for the sublayout so you can test different content much like you would setup DMS personalization . If your content is not structured into page components you cannot execute the tests . There are several companies out there that will audit your build to determine your solution s DMS-readiness and you can probably get them to fix up your build to support DMS as well . If you will be doing it yourself here are the basic steps : .. . .. . 1 . Split up your page layout into sublayouts . At the very least the portion that you want to test should be in its own sublayout . 2 . Create new component templates for your content that will be displayed in these sublayouts . This will be the data for your datasource . 3 . Create new content items from your new component templates to represent the data variations you want to try . 4 . Update the code for your sublayouts to access the Datasource property of the sublayout to find the content Item instead of using Sitecore.Context.Item .. . 5 . Using Page Editor configure your page component datasource to pull from one of your new component content items . Comment : That makes sense . I didn t realize that the components that you re creating test variations for had to be sublayouts with data sources - before you go in and configure the test variants .", "Question : Hi am trying this code .. . .. . and then from cshtml .. . .. .

I don t think there is an option to do that but I might be wrong Comment : @MarekMusielak Yes sorry misunderstood you . But you are right you have to go up the tree and add it as a child . .. . Answer : In order to be able to use the Insert Page button the item you are inserting under must have Presentation defined . It doesn t need to have components added and I ve worked round this before by simply define a blank layout and setting it on those items . Maybe create yourself a new template inheriting from Folder and then set Layout on that . But this is a workaround at best . You can only Insert Page below the current page you are on so you would essentially have to navigate to a blank page in order to create the sibling . From what you have stated it sounds like you may want to re-think where your Insert Options have been set and your content structure i.e . why would you want create another Home item Creating so will require set-up of another site and related config . You probably also want to separate those sites out with other settings there is some good example of multi-site structure in this blog post http : learnsitecore.cmsuniverse.net en Developers Articles 2009 10 how-to-multisite-in-sitecore.aspx .

But difficult to know what you are doing without context.. .", "Question : I would kindly ask for your help : From couple of days I am trying to achieve linked custom field in content editor and dropdown in page-editor . Basically I want to have dropdown in page-editor and content editor which are responsible for a same thing . In my c code i have enums which represent directions . I created custom field which accepts assembly and class with overridden onload method and successfully populate dropdown values in the content editor . So far so good but i have no idea how to create dropdown which will represent the same functionality inside page-editor . So please give me any ideas.. . Comment : Correct me if I m wrong but you are trying 2 things : 1 adding a custom field type to sitecore and 2 having that custom field show up as a dropdown in page-editor mode . If I understand correctly you succeeded in part 1 but are struggling with part 2 right Comment : Yes . I successfully created the custom field . As you said in part 2 I am trying to do the same thing in page-editor . I think that a possible solution might be creating page-editor component which i hove no clue how to do : Comment : I think this question deals with far too big a topic to be answered here . I suggest reading the Presentation Component Reference before you attempt to continue sdn.sitecore.net upload sitecore6 64 http : sdn.sitecore.net upload sitecore6 64 presentation component reference-a4.pdf .. . Answer : Judging from your reply to my comment you need to think of the following : How is my field value being rendered onto a page .. . .. . If you are always using 1 control to do this then you just need to ensure that this control has 2 different rendering modes depending on the Context.PageMode .. . .. . But as I understand it you want this dropdown to also appear when someone renders your custom field using a sc : FieldRenderer . In this case you ll need to look into the RenderField pipeline of Sitecore . There you find a processor called RenderWebEditing . Possibly through some manipulation here you can get your dropdown appear as you wish .", "Question : I have a layout with two place holders leftColumn and rightColum . For an item i am adding multiple sublaouts for leftcolumn and multiple sublaouts for rightcolum . Now in page-editor when i am trying to change position using Change Position button in toolbar and move content to another location content is getting moved to my new location as desired . But when i click Save button on Ribbon it is actully deleting moved content from presentation itself . I am not sure why it is behaving like this . we are using Sitecore 6.4 Comment : Looks like a bug you should probably contact Sitecore support . Comment : What happens in the Sitecore content editor under Presentation Layout Details for the item .. . Answer : Can you see anything through Sitecore Logs It may have any errors or exceptions that are being generated ." ] }

Answer : fabric8 v1 is part of JBoss Fuse and you can find documentation how to use it as part of the JBoss Fuse product documentation : http : developers.redhat.com products fuse overview .. . .. . The Maven Archetype goal to use is different version number than what you type you must use the version number of the JBoss Fuse product version you use .

What am I missing and how can I fix it Am I doing something strange and unsupported .. . Answer : We had an issue with the Ingress controller pod which looks like it s been fixed but I ve not had a chance to try it out yet https : github.com nginxinc kubernetes-ingress issues 34 .. . .. . So for now we ve been using the Google Container loadbalancer as it automatically creates external IPs for our services . We ve just updated our GKE docs so hopefully things are a bit clearer . From the docs we ve also linked to a silent demo of running fabric8 with CD pipelines etc on GKE so that might help too . http : fabric8.io guide getStarted gke.html .. . .. . FWIW to access the fabric8 console we use a service proxy from the Kubernetes API server the console inself then uses either ingress or external ips to access Jenkins Gogs Nexus etc Comment : To get the external ip s from the CLI rather than the fabric8 console you can run kubectl get services and get the external ip-address for each service . They can take a minute to create and you also need to watch out incase you exceed your GKE quotas these can be checked in the GKE dashboard .

Answer : If you are trying to access a service on OpenShift remotely then you need to ensure you ve deployed a router added a Route . You can read more on routing in OpenShift at https : docs.openshift.com enterprise 3.0 architecture core concepts routes.html . In this case if you add a route with : .. . .. . cat EOF kubectl create -f - apiVersion : v1 kind : Route metadata : name : fabric8-console pec : host : EXTERNALLY RESOLVE DNS to : kind : Service name : fabric8 EOF .. . .. . As some extra info you cannot target ping at a port . Ping uses a different network protocol ICMP which doesn t have the notion of ports . Also both services pods don t respond to ping so you will not be able to ping them . If you re trying to check connectivity then you can use the nc utility : .. . .. . This will report connection success if the address port is reachable . Note that in OpenShift pod IPs service IPs are generally only routeable inside the cluster i.e . on nodes so trying this from outside the cluster will probably fail . Comment : Thank you very much .

This is the configuration that successfully worked for me : Comment : where-in the pom is this located and what goal do you execute and what isn t working the way you go seems correct if you run the pre-integration-test phase the fabric8 plugin should do something . .. . Answer : The way we recommend integration and system-testing in maven with docker is via the fabric8 arquillian plugin http : fabric8.io guide testing.html . That takes care of creating a new namespace for the test and provisioning all the kubernetes resources then running your JUnit test case to run the assertions etc .

When I read about Karaf http : karaf.apache.org documentation.html they always use Blueprint instead of Spring and I don t get the impression that it s possible to use it with Spring boot . Then I found Fabric8 http : fabric8.io but I cannot find any example of micro services made with Spring boot . All I need is being able to do hot deployment and configuration at runtime like Karaf does but with multiple Spring boot services . Is it possible Could anybody give me documentation or a project sample Thank you Comment : should this question rather be on programmers.stackexchange.com Comment : Read this article from source : spring.io blog 2015 07 14 microservices-with-spring https : spring.io blog 2015 07 14 microservices-with-spring with battery included . Comment : @Alex if this question is about Spring then no . If this question is about microservices then maybe . But this question is about Spring so no . Comment : @Alex I wasn t sure . I will let a moderator move my question if needed Comment : @DoNhuVy Oh that looks perfect I will read asap .. . Answer : Here s a demo video showing how to create a Spring Boot microservice https : vimeo.com jbossdeveloper review 170830750 b3c8467593 in the Fabric8 Microservices Platform http : fabric8.io and having a complete Continuous Deployment pipeline http : fabric8.io guide cdelivery.html get created to do the following : .. . .. . package the code create the docker image and kubernetes manifest .. . perform system integration tests .. . deploy to the staging environment with rolling updates .. . wait for optional human approval .. . deploy to the production environment with rolling updates .. . .. . Any code or configuration change in the git repository kicks off rolling updates automatically - which is a form of hot deployment . e.g . if you are running 3 containers in production new containers are spun up with the new code and or config based on the rolling upgrade policy . Typically new containers start when they are ready old ones are taken down say 1 at a time or you can do them all at once if you prefer . The rolling upgrade is included in any service load-balancing so new containers only get invoked when they are ready . Given your use of OSGi you may want the containers to keep running and just mutate on the fly . Firstly the whole move to immutable infrastructure e.g . docker images means software gets simpler and easier to reason about . Rather than rolling new bundles code config in out on the fly you just make a new image and spin that up . Mutating on the fly leads to multi-threaded code having to stop and restart services on the fly which can cause all kinds of complex hard to reproduce bugs and resource leaks as you have large complex object dependency graphs of services starting stopping on the fly . On the Fuse team we ve wasted many man years fixing bugs in restart logic and I m sure there s still a zillion bugs hidden there in restarting OSGi services on the fly . So my preference really is to use a Continuous Deployment pipeline http : fabric8.io guide cdelivery.html to roll out all changes whether code or configuration . Sure there s some latency added between the time you make a change and the moment a process is processing a new request with the new code config - but you have more quality and reliability baked in . Plus its trivial to roll back . You can also easily do rolling upgrades of the change so you get fast feedback if the change breaks things for a small subset of your users traffic rather than a big bang . That being said if you still really really want production JVMs to reload code and or config on the fly without testing it first in a big bang approach with no easy rollback there are still some options available . They are described in the configuration microservices documentation http : fabric8.io guide develop configuration.html . Essentially it boils down to using a ConfigMap in Kubernetes http : kubernetes.io docs user-guide configmap or a git repository volume http : kubernetes.io docs user-guide volumes gitrepo in both cases the configuration is exposed as volumes files - the Java code can then watch the files and reload on the fly . You can do this via OSGi Config Admin or via Spring Boot http : docs.spring.io spring-boot docs current-SNAPSHOT reference htmlsingle howto-hotswapping - whichever development framework you pick really . Just remember the tradeoff of the benefits in latency from hot-reloading from the reduced quality increased bugs and operational issues of moving away from immutable infrastructure and Continuous Delivery Comment : Completely agreed especially in a Microservices world where turnaround times are supposed to be quick because of the smaller artefact footprints . It should to be affordable to restart whole micro apps in order to get to a well defined always reproducible state . And since it mirrors the way applications are operated in production its a more realistic workflow . But this only works really well if development roundtrip times can be kept short which is imho a key requirement . Comment : I agree that hot deployment is not necessary to have short dev cycles . I personally work with OSGi in the same way as James showed for spring-boot . I create fully packaged deployment units in an automated pipeline . The main difference is that I propose to not start with microservices but rather a modular application in one process . It is much simpler . Then if needed you split out the modules with different team or dev cycles as individual microservices .", "Question : I get the following on a native openshift fabric8 installation . this then results in not been able to access the fabric8 console .

Tail of the logs are as under : - .. . .. . Can someone help me solve this .. . Answer : If the state of the pod goes in to CrashLoopBackOff it usually indicates that the application within the container is failing to start up properly and the container is exiting straight away as a result . If you use oc logs on the pod name you may not see anything useful though as it would capture what the latest attempt to start it up is doing and may miss messages . What you should do is instead provide the --previous or -p option to oc logs along with the pod name . That will show you the complete logs from the previous attempt to start up the container . If this is an arbitrary Docker image you are using a common problem that can occur and which would cause the container not to start is an application image which requires to be run as the root user . Because running an application inside of a container as root still has risks OpenShift doesn t allow you to do that by default and will instead run as an arbitrary assigned user ID . The application image may not be designed with this possibility in mind and so is failing . So try and get those logs messages and see what the problem is .

Comment : That has done the trick in the example code : pint owed . If you propose as an answer I ll flag it as such . .. . Answer : It s highly likely your looking at an OS specific artifact rather than a core problem with QT . I ve seen this issue so many times in so many tool kits and frameworks that it scares me that no one has yet figured out an elegant solution . The Basis of the Problem .. . .. . Most operating systems implement some kind of protection for critical system files . Under nix this is in the form of the user group permissions system under windows it s similar but with the UAC User Access Control sub system . What this boils down to is that you often can t just pick an arbitrary location to write files to not without first seeking permission from the various security API s and mechanisms in the OS to do so . The second half of the problem then comes from variable expansion . In nix particularly the tilde char is expanded by the shell to mean the users home-directory . When we say shell we mean bash tch csh or what ever environment your running the app in . Within this mix we ll also put the desktop environment too as most things like Kde Gnome Unity or what ever else is being used have some kind of operating-system call that when a is passed to it knows to convert it to home neil or what ever it needs to be expanded too . Windows also has a similar thing whereby you can make an OS call and say Hey mr operating-system where are my user folders stored which it will happily reply to with something like c : users .. . .. . Why The Problem Manifests The Way It Does .. . .. . Simply because when your in charge of creating the path strings yourself in your own application things are often not passed to these various OS calls for expansion and security clearance you pretty much have to make sure your the one that calls them . The exception to this rule is if your using the nix philosophy of small tools combined to do one job . In this case you would often pass a result to a shell based program which because it s running via the shell then knows that if it sees it has to expand it . Beacuse your using direct file-access managing your own file paths when you thought you where writing to home neil file.mov you where-in actual fact trying to write a file called file.mov in the current folder where your app is running from in a folder called which I m willing to be doesn t exist . Add to this the fact that a lot of these frameworks QT is no exception are designed to hide and abstract away all the ugly details there s a good chance it consumed the OS exception that was generated when you actually tried to write the file if it had not then your app would most likely have crashed with some kind of exception dialog . How to Solve The Problem .. . .. . There are 3 approaches you can take to mitigating this . 1 You can hard code the paths that is you can explicitly say to the application always store your file at home neil videos blah.mov this has a disadvantage however that every user of the app will need a custom build as it s unlikely person2 will have write permissions on neil s home-directory . 2 You can build in functionality that gives the user a dialog box and asks them where they would like to save the file . Since your using something like QT this should be very easy most of these UI tool kits have built-in functionality to easily present the user with such an experience . 3 You can find out if your framework or the underlying OS has any calls for you to ask who the current user is and where their home-directory is you can then use the returned information to dynamically build a static patch similar to that in option 1 . Doing things this way ensures that the application adapts automatically to it s environment irrespective of the user . Myself personally I generally adopt option 1 during development then when development is complete I switch to number 2 very rarely do I use number 3 in desktop based software . Option 3 for me is often used when the application in question is designed to do a single job such as converting a file for another process to work with or generating some output for a server to display in a web page etc . For you right now as a solution to this question however Option 1 is your best bet .", "Question : I am using Qt framework and I would like to generate mouse events outside my application window .

As stated in the link you pasted : If a version directive does not appear at the top then it assumes 1.10 which is almost certainly not what you want .

Nvidia drivers lets you get away with it but Intel s does not I do not know about ATI s so perhaps the developers in charge did not test on different enough hardware configurations . As it is there is no easy workaround you could change the Qt code not to add those defines which is a distribution nightmare or not use the QOpenGLShader class which means house keeping the raw OpenGL objects yourself .

A string literal such as @ c : Foo is called a verbatim-string literal . It basically means don t apply any interpretations to characters until the next quote character is reached . So a verbatim-string literal can contain backslashes without them being doubled-up and even line separators . To get a double-quote within a verbatim literal you need to just double it e.g . @ My name is Jon represents the string My name is Jon . Verbatim string-literals which contain line separators will also contain the white-space at the start of the line so I tend not to use them in cases where the white-space matters . They re very handy for including XML or SQL in your source code though and another typical use which doesn t need line separators is for specifying a file system path . .. . It s worth noting that it doesn t affect the string itself in any way : a string specified as a verbatim-string literal is exactly the same as a string specified as a normal string literal with appropriate escaping . The debugger will sometimes choose to display a string as a verbatim-string literal - this is solely for ease of viewing the string s contents without worrying about escaping . .. .

Comment : Because your computer and no other for that matter doesn t know where you want your string to stop Not interpreting escape sequences is one thing but that one character is still special.. . Comment : Is this a question or a rant Also you seem to ask about a C language design decision while you don t really understand the basic syntax . Comment : @RowlandShaw @ed @kobi @rominox : It can know where the string ends by using predecessor of the inner quote . E.g . : @ 1 2 The quote preceding 1 can be used as start point and quote preceding can be the end point whatever in the between is the required string . Why an extra pair .. . Answer : So technically string s @ Hello should print Hello .. . .. . No that would just be invalid . The compiler should - and does - obey the rules of the language specification . Within a verbatim-string literal double-quotes must be doubled not tripled to distinguish them from the double-quote just meaning the end of the string . It s easiest to see this if you use a double-quote within the middle of a string not at the start or end : .. . .. . F works perfectly in the above case .. . .. . Not as far as I can see . In a sample F project in VS2015 Preview : .. . .. . .. . gives an error whereas @ Hello results in a string of Hello . Additionally the F verbatim-string literal documentation http : msdn.microsoft.com en-us library dd323829.aspx suggests it works exactly as per C : .. . .. . If preceded by the @ symbol the literal is a verbatim-string . This means that any escape sequences are ignored except that two quotation mark characters are interpreted as one quotation mark character . Basically it sounds like verbatim-string literals work in both C and F perfectly well with both of them requiring double-quotes to be doubled . F also has tripled-quoted strings within which they don t need to be doubled.. . but that s just a separate feature that C doesn t have . EDIT : To answer your comment about ambiguity you gave an example of @ 1 2 . Let me change that very slightly : .. . .. . In C at the moment that means the concatenation of a verbatim-string literal with content 1 and an empty regular string literal . If you re proposing that it should actually be a single verbatim-string literal with content 1 + with the parser relying on the quote directly before the next semi-colon being the end of the verbatim-string literal that strikes me as a really bad idea . For example suppose I want to use a verbatim-string literal as the first argument in a two-argument method call like this : .. . .. . By your rules that would be a call with a single argument - it would be impossible to represent the call we re trying to make as a single statement . You d need to use a variable for the verbatim-string literal to avoid it messing things up . In short I m happier with the way C already works . Comment : : Thanks for answering but the confusion still prevails . The parser can understand the start and end point of the string by utilizing the first occurring and last occurring before . For e.g . : @ 1 2 The quote preceding 1 can be used as start point and quote preceding can be the end point the content in between these two points should be parsed as string . Why an extra pair is needed by the compiler to parse it effectively Pardon for my queries but I m trying to learn C from basics as am a student . Comment : @Chaz : No that s not how the parser works - and it can t be as there could be x + y for example where the end of the first literal is not the last quote before a semicolon . The parser works by consuming tokens as it goes - it needs to know whether it s in a string literal or not . Take your example but change the 2 to a + . Is that now a single verbatim-string literal or a verbatim-string literal concatenated with a regular string literal in your hypothetical language Comment : jon : The parser works by consuming tokens as it goes - Oh How can I forget this from my Compiler Design classes Thanks a lot Sir Skeet as your counter question made it clear for me .

Answer : That s because you need to have an opening and a closing characters too . So with a line like yours : .. . .. . The first and the last quote characters is to indicate the start and the end of the string to the compiler .

Answer : Can you try threading instead Multiprocessing is basically for when you are CPU bound http : stackoverflow.com questions 1226584 multiprocess-or-threading-in-python . Also boilerpipe already includes protection when using threading https : github.com misja python-boilerpipe blob master src boilerpipe extract init .py L51 which suggests that it may need protection in multiprocessing also . If you really need mp I will try to figure out how to patch boilerpipe . Here is what I guess will be a drop-in replacement using threading . It uses multiprocessing.pool.ThreadPool which is a fake multiprocessing pool http : stackoverflow.com questions 3033952 python-thread-pool-similar-to-the-multiprocessing-pool . The only change is from Pool . . to multiprocessing.pool.ThreadPool .. . The problem is that I m not sure the boilerpipe multithreading test will detect the thread pool as having activeCount 1 . Comment : @dpatro even if you actually need multiprocessing could you try this If this works then it might be straightforward to patch boilerpipe for multiprocessing protection . Comment : I also thought of same github code . Moved to Java a week back to make boilerpipe run . Will check it out today and update the thread . Comment : Checked and it is working for continuously over a day now . The processing is slowed down a bit though may be due to the library . Thanks @kobejohn for the insight to the solution . Comment : @dpatro that s great news . Thanks for letting me everyone know it works . If multiprocessing worked faster then it may be boilerpipe or the other parts of your code that are faster . If you can remove the other parts of the code and demonstrate that boilerpipe is significantly faster with multiprocessing that would be a great way to submit a feature request on github . Comment : I got a chance to check things properly . It turns out that ThreadPool is faster than ProcessPool .

Answer : There are many scripts extracts articles from html pages . If using regular expression to get the only main article from html or PHP page source what is the best regular expressions to get only the main article . Also what is the simplest and the best ways to get those without regular expressions in PHP or other programs only . Some scripts are using many filters to extract the main article from html or PHP source with problems of non-English languages characters and multi-byte characters . As the results they can not good portion of the main article from the source because the above problems . Normally the main article must be in div p or other tags in the html or PHP source . Then other html elements in the page with navigations links extracts and others . Using regular expressions can solve the prior problems easily by defining multi-byte character and language differences in the expressions . Most of the article extraction software uses filters to find comment first next nav button submit and others to check if the portions they are holding are the content or other elements . The tags ids classes and other tags are most likely only valid in English and ISO-west-European character only . They can not extract exact portion of the article because they do not understand the languages or the characters they are trying to filter . The Below algorithms to filter articles from the other elements used by an article extraction script source boilerpipe http : code.google.com p boilerpipe are using If you examine the src files closely . 1 . Check if the characters are long enough . character and word-count .. . 2 . Check if the tags are on suggest list comment first next nav and others . array searches with or without regular expressions .. . 3 . Other checks to verify the article from other html elements heuristic and others . There are theories of article extraction of webpages but not simple than using regular expressions . They can convert to simply regular expressions or other simple programs . The boilerpipe http : code.google.com p boilerpipe written in java to extract articles but it is too complex and the problem of the languages and characters . Preferably using both several regular expressions and some other regular program to filter the article is better . The exact things that I m looking for are below .. . .. . Regular expressions to extract only the articles from html and PHP pages . Using few regular expressions to extract only the article from html or PHP source without any other elements and other expressions to check non-article possibility . Non regular expressions to extract only the articles from html and PHP pages . Using PHP to extract only the article from html or PHP source without using regular expression in simple way . Also need check if the article or not . Both of them must not in language and character set limitations example of multi-bytes and simple sufficient to fit a single page .

Answer : You ve clearly been able to get ArticleExtractor to parse utf-8 text . The likely problem is that boilerplate s algorithms are specifically tailored to English and aren t working so well on a Gujarati article . The algorithms use verbosity of phrases eg : number of words per phrase as well as some specific phrases comments have your say etc to determine the barriers of the article as well as what pieces within the article are content or non content . Have a look in the boilerpipe filters english directory of the library for more info on the algorithms . Unfortunately to get the same level of accuracy in non-English languages you would need to repeat their study on each language or have a list of translated stop-words and an idea about verbosity for each language you use .
