Answer : I ve been playing around with shadows on Lollipop for a bit and this is what I ve found : .. . .. . 1 . It appears that a parent ViewGroup s bounds cutoff the shadow of its children for some reason and .. . 2 . shadows set with android : elevation are cutoff by the View s bounds not the bounds extended through the margin .. . 3 . the right way to get a child view to show shadow is to set padding on the parent and set android : clipToPadding false on that parent . Here s my suggestion to you based on what I know : .. . .. . 1 . Set your top-level RelativeLayout to have padding equal to the margins you ve set on the relative layout that you want to show shadow .. . 2 . set android : clipToPadding false on the same RelativeLayout .. . 3 . Remove the margin from the RelativeLayout that also has elevation set .. . 4 . EDIT you may also need to set a non-transparent background-color on the child layout that needs elevation . At the end of the day your top-level relative layout should look like this : .. . .. . The interior relative layout should look like this : Comment : Thanks for this I also found android : clipChildren false to be useful when applied to the parent relative layout .

Its parent clips all child views within its own drawing canvas and is the view that handles the child s shadow . You can fix this by applying an elevation property to the topmost RelativeLayout in your view xml the root tag .", "Question : Elevation make Sliding Tab Layout worked fine on Lollipop device but tabs will disappear on pre-lollipop device .

Answer : To bring dynamic animated shadows to pre-Lollipop devices you have to : .. . .. . 1 . Draw a black shape of a view to a bitmap .. . 2 . Blur that shape using elevation as a radius . You can do that using RenderScript . Seems like it s the method Lollipop s using . 3 . Draw that blurred shape beneath the view . Probably the best place is the drawChild method . You also have to override setElevation and setTranslationZ override child view drawing in layouts turn off clip-to-padding and implement state animators . enter image description here http : i.stack.imgur.com 3W2LQ.png .. . .. .

A service method is passed a collection of named arguments based on whatever is in the request context after the controller methods have executed i.e . after before startItem and item .

The following view displays rc.autocomplete not yet implemented .. . .. . views comparables autocomplete.cfm Comment : suppressImplicitService is set to true by default in v2 therefore you should really invoke your own service s and put the results in rc yourself . See : github.com seancorfield fw1 wiki Developing-Applications-Manual https : github.com seancorfield fw1 wiki Developing-Applications-Manual Comment : Henry the call to service in the controller is doing this placing the result in rc.autocomplete . suppressImplicitService true means the service isn t automatically called and placed in rc.data which was the 1.x behavior . Comment : The code looks correct to me assuming that rc.term is defined before the service call . What do you see when you dump the arguments scope from within the service function Comment : Thanks for the help . I believe that it was getting cached . When I did a reload true things improved and started working . I ll post any corrections when I get back to work tomorrow . .. . Answer : I was finally able figure out how it all fits together .

But it d add one more layer of complexity with repository structure and workflow and IDE second project effectively for me personally . Comment : @Sergii this is the established way of achieving what you are asking for . You shouldn t have to create a new project . You can just have folder structure that supports it . i.e . www this is your webroot views this is where your views go then you promote it as a mapping . The mod-rewrite route will work but it is a bit of a sledgehammer approach to something that can be solved by CF itself Comment : I m sorry but it is not . We are talking here about FW 1 right . Project structure is defined by framework -- it is convention-based . One can override it of course but it doesn t look as wise choice for long term maintenance . For example if some other applications follow standard structure it d be confusing . Comment : I know that . It only cares where ColdFusion thinks it is though so creating a mapping tells it the answer . It is obviously your choice but I think you are just making it hard for yourself . Comment : You know I think your answer was incorrect from very beginning . Let s say I ve created the mapping for views which actually lay outside of the webroot .

Answer : If you want to do the purest form of SES URLs http : site.com controller action it requires the removal of the index.cfm which involves having to do some URL rewriting on the web server-side . No framework that I know of can avoid URL rewriting if you want to remove the index.cfm .. . .. .

Answer : You can create a method in a controller that checks rc.action to see if the item part starts with a and redirects elsewhere or throws an error or whatever you want to do . Then call this method using controller function in your setupRequest method in Application.cfc . For example I have a controllers security.cfc controller with checkItem method as follows : .. . .. .

The choices have been narrowed down to either CFWheels Coldbox or FW 1 . My question is which of those three would be faster and easier to convert to when moving from a Fusebox no XML site Thank you .. . Answer : Ease of conversion is the wrong question . Conversion is a one-time event . Maintenance is an on-going situation and is a far more important factor to base your decision on . Investigate your shortlist - they all come with sample applications - and determine which one you d rather work with going forward then do what it takes to convert - none of the three should be especially difficult . Though I ve only dabbled with cfWheels and ColdBox so can t guarantee there isn t some hidden gotchas that make them more complicated to convert but again if they re easier for your team to work with that s more important . Comment : Thanks for the response . Are you suggesting that it is all a matter of preference or that some might be more cumbersome to work with If it is just a matter of preference then I might as well close the question . Comment : Kinda - depends how you define preference - they all have different aims and it depends how those align with the developers using them . FW 1 is built to be deliberately lightweight etc . ColdBox is built to be full-stack enterprise . cfWheels is built to do whatever Ruby on Rails does . So for a RoR developer FW 1 and CB would probably be more cumbersome . Comment : Makes sense .

Answer : We have the concept of a dynamic text area on some pages on applications that don t require a full on cms . This is with ColdBox but you should be able to implement something similar in fw1 . We have a helper component with a method that allows us to render dynamic text with a specific code eg . helppagetext in a zone in the page .

The first RewriteCond makes sure that the file does not exist - so if you have a real file css default.css any requests for that will fail this condition and not redirect . The second RewriteCond accepts any alphanumeric for the first segment then continues if there is a at the start of the second segment . It s not necessary to match the entire URI just the start is enough . Finally the RewriteRule is applied only if both conditions were true but matches all URLs and performs a server-side redirect to error 404 - you can update that part as appropriate .

I know that it is possible to convert my form fields into a ColdFusion struct because as I said CFWheels does it . I just have no idea how to make my application do it . Here is part of the form that I am talking about Comment : FWIW your Form scope is already a Struct . That s true of all variables scopes . Comment : @Al Yes all variable scopes have their own structs but in FW 1 my form and url scopes get mixed together along with some other stuff . I need just my form scope which is not accessible as far as I know . Comment : As Al said form is a struct which you can manipulate like any other structure . Comment : FW 1 puts URL and form variables in the RC struct true but it doesn t destroy the Form struct . You can still use it if absolutely necessary . Comment : Thanks Al . I didn t realize that it was accessible from controllers . I will stick with Adam s solution as it is reusable for any scope . .. . Answer : Adam had the right context but his code snippet was wrong . A function that will work is this : .. . .. . I tested it in my application outside of CFWheels and it worked perfectly . All you do is pass in a struct in my case the Rc struct from FW 1 containing what should be structures but displaying as strings and you will be returns a structure with nested structures . Example : Comment : +1 for the right function .", "Question : null .. . Answer : This is happening intermittently usually at start up . I get the above error message when executing the following code . The first line executes fine but the second line blows up . The solution is to run ormreload .. . .. . The problem keeps coming up in an unpredictable way though . Even when no changes have been made to the beans or gateways that are using ORM . Completely unpredictable and impossible to replicate on purpose . Is there something else that can mess with the hibernate mappings that could cause this type of problem . Other info that may be pertinent : .. . .. . This is a MURA plugin based on a recent version of FW 1 . ormreload is a persistent fix until it fails again .. . .. . My current solution is to put ormreload in the setupApplication method of application.cfc .. . .. . I just want to understand better what could be causing this problem . Comment : Dumb question here...but do you really need to covert the array to a query I use ORM extensively in my applications and I have never had a need to use entityToQuery . If you really need a query object why bother with ORM Just run a SQL query instead . Comment : @ScottStroz Great question . I have rarely used CF ORM in the past . I had my own lightweight ORM that worked really well for me . Now I m working with an inherited app and I m trying keep tools consistent throughout the existing project . In this case I m trying get a list of all priorities so that I can populate a pick list . The picklist is a built using some customized UI tag libraries also inherited . So the picklist is looking for a query object . So I could refactor but still trying to figure out why entityToQuery is flaky for me . Thanks for the suggestion though . I may go that way . Comment : Make sure that var arr is not an empty array . entityToQuery only works if there are rows in the array . Comment : Using ORM and then converting to a query could be a lot of overhead . Which is why I tend to stick to one or the other . Comment : @JamesAMohler Array is not empty . Note that ORMreload fixes the problem . And it isn t a cache issue...dump and abort shows values . Removing the abort throws the error . Then ormReload fixes the problem .", "Question : I am currenting using FW 1 and tracking traffic via the following function-call .. . .. . Currently it is ran on setupRequest in application.cfc . I have two subsystems : home and admin . home will always have it traffic tracked . Admin will never have its traffic tracked . I am considering moving the function-call to home layouts default.cfm because only the home subsystem is tracked . I don t want to move the traffic tracker there because this has nothing to do with layouts . Where should traffic logging be done on an FW 1 site .. . Answer : It would be done in setupRequest where you are currently doing it . To avoid it occurring for the Admin subsystem wrap it in a conditional check for getSubSystem NEQ admin before running it . Alternatively if you forsee adding multiple subsystems with different statuses you could implement it instead by creating a TrackedSubsystems or UntrackedSubsystems item in Variables.Framework with a list of subsystem names then check for : Comment : I like the idea of using Variables.Framework.TrackedSubSystems as it is self describing .", "Question : I ve got a FW 1 app on Railo 4.2.2 Apache and for some reason it s calling onApplicationStart on every request . I can tell it s not any reinit code - put in a callStackGet dump in setupApplication and can see that the root call is onApplicationStart not via any init hook . Are there any known bugs in Railo that would cause this I ve double checked the application timeout 1 day and the FW 1 setting - it s turned off - so there should be no reason the app would be losing application scope on every request . There is another strange thing I m seeing too but I don t know that it is related . In setup application I am creating a new user object via ORM and persisting it if a local admin doesn t exist . I dump it and see the ID but it s not in the database when I query the table yes I flushed it . The next page hit creates the user again since it doesn t exist still.. . . Edit : Add persist object code for Adam . Comment : Are you setting the application name Comment : Agreed with Bardware if you re not setting an application name or are setting it to something random every time that could cause this behavior . Comment : As for your ORM user creation bug post the code man . Comment : Application name is set yes . And no there is no duplicate application running locally . @AdamTuttle - come on man you know I know how to create and persist a simple user Comment : I would usually give you the benefit of the doubt true . But if you don t want to post code how can you expect help Anyway to identify if it s some sort of bug with creating entities in onApplicationStart which is calling FW 1 s setupApplication try moving the same code into index.cfm or something . Double check that it s not your persistence code . Think like a scientist and isolate those variables . .. . Answer : I think the failure to persist to the DB may be a regression bug with Railo 4.2.2 . See https : issues.jboss.org browse RAILO-3279 .. . .. . Try wrapping your save flush in a transaction : .. . .. . Normally you shouldn t need both . Either the transaction or ormFlush should make it persist ." ] }

Standalone setup .. . 2 . WebApplicationContext setup .. . .. . In general what kind of testing is MockMvc used for Unit or Integration or Both Am i right in saying that using the standalone setup running outside the Spring s application context allows you to write unit tests and with the WebApplicationContext setup you can write integration tests .. . Answer : Both forms are actually integration tests since you are testing the integration of your code with the Spring DispatcherServlet and supporting infrastructure . The difference lies in the amount of supporting infrastructure that is used behind the scenes . The details are documented in the Spring reference manual . Server-Side Tests http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html spring-mvc-test-server .. . Setup Options http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html spring-mvc-test-server-setup-options .. . Difference With End-to-End Integration Tests http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html spring-mvc-test-vs-end-to-end-integration-tests .. . .. . Noteworthy excerpts : .. . .. . The webAppContextSetup loads the actual Spring MVC configuration resulting in a more complete integration test . Since the TestContext framework caches the loaded Spring configuration it helps to keep tests running fast even as more tests get added . Furthermore you can inject mock services into controllers through Spring configuration in order to remain focused on testing the web layer . .. . .. . .. . The standaloneSetup on the other hand is a little closer to a unit test . It tests one controller at a time the controller can be injected with mock dependencies manually and it doesn t involve loading Spring configuration . Such tests are more focused in style and make it easier to see which controller is being tested whether any specific Spring MVC configuration is required to work and so on . The standaloneSetup is also a very convenient way to write ad-hoc tests to verify some behavior or to debug an issue . .. . .. . .. . Just like with integration vs unit-testing there is no right or wrong answer . Using the standaloneSetup does imply the need for some additional webAppContextSetup tests to verify the Spring MVC configuration . Alternatively you can decide to write all tests with webAppContextSetup and always test against actual Spring MVC configuration . .. . .. . .. . The options provided in Spring MVC Test are different stops on the scale from classic unit to full integration tests . To be sure none of the options in Spring MVC Test are classic unit tests but they are a little closer to it . For example you can isolate the service-layer with mocks injected into controllers and then you re testing the web layer only through the DispatcherServlet and with actual Spring configuration just like you might test the database layer in isolation of the layers above . Or you could be using the standalone setup focusing on one controller at a time and manually providing the configuration required to make it work .

The Spring ApplicationContext will be reloaded after the execution of the test . Comment : Thanks Spring seems to cache based on the locations param in the ContextConfiguration annotation : @DirtiesContext classMode ClassMode.AFTER CLASS works for me Comment : There is no need to specify classMode ClassMode.AFTER CLASS . That is the default Please read the Javadoc for classMode .", "Question : I would like to write Junit test cases for REST API .

The above Junit code returns 404 response instead of 200 . I want to rollback the data when test is done .. . .. . Pleas help me to resolve the issues .. . Answer : As the name implies the Spring MVC Test Framework is for testing Spring MVC Web and Spring MVC REST applications . You are writing a CXF REST application which is based on JAX-RS . Spring MVC REST is not an implementation of JAX-RS . It is therefore not possible to test a JAX-RS application with Spring MVC Test i.e . MockMvc . To test your JAX-RS endpoints you will need to use a testing framework with dedicated support for JAX-RS . For example you may want to use the JAX-RS Testing https : cwiki.apache.org confluence display CXF20DOC JAXRS+Testing support from CXF or you can Google jax-rs testing to find other solutions .", "Question : I am using junit 4.12 jmockit 1.19 spring-test 4.1.1.RELEASE for testing my Spring MVC Java project .

So you don t need the SpringJUnit4ClassRunner : docs.spring.io spring docs current spring-framework-reference http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html testcontext-junit4-rules Comment : I believe you would need to show an example test class and an example pom.xml file that reproduces the issue . I have tested this combination of tools jmockit junit and spring-test but saw no initilalization failures . .. . Answer : I m not entirely sure this will resolve your problem as I just started using jmockit myself and running into similar style issues . Have you tried using -javaagent : Easiest way to apply to all JUnit tests Eclipse is to go to your JRE settings and add as a VM Argument Preferences- JRE- Edit- VM Defaults . Additionally I found an Eclipse JMockit plugin via the Marketplace that will automatically append the javaagent to any junit tests to avoid the JRE configuration . Finally in your POM you can try although I haven t tested it myself yet : .. . .. . However keep in mind that this would only work for maven launched tests and not through the IDE .

Using JUnit @BeforeClass annotation : .. . .. . Using the Spring hook : .. . .. . 1 Override beforeTestClass TextContext testContext : .. . .. . 2 Use @TestExecutionListeners annotation : .. . Answer : TestExecutionListeners are a way to externalize reusable code that instruments your tests . As such if you implement a TestExecutionListener you can reuse it across test class hierarchies and potentially across projects depending on your needs . On the flip side a @BeforeClass method can naturally only be used within a single test class-hierarchy . Note however that JUnit also supports Rules https : github.com junit-team junit wiki Rules : if you implement org.junit.rules.TestRule you can declare it as a @ClassRule to achieve the same thing.. . with the added benefit that a JUnit Rule can be reused just like a Spring TestExecutionListener . So it really depends on your use-case . If you only need to use the before class functionality in a single test class or a single test class-hierarchy then you d be better off going the simple route of just implementing a @BeforeClass method . However if you foresee that you will need the before class functionality in different test class hierarchies or across projects you should consider implementing a custom TestExecutionListener or JUnit Rule . The benefit of a Spring TestExecutionListener over a JUnit Rule is that a TestExecutionListener has access to the TestContext and therefore access to the Spring ApplicationContext which a JUnit Rule would not have access to . Furthermore a TestExecutionListener can be automatically discovered http : docs.spring.io spring docs current spring-framework-reference html testing.html testcontext-tel-config-automatic-discovery and ordered http : docs.spring.io spring docs current spring-framework-reference html testing.html testcontext-tel-config-ordering .

I currently use @ActiveProfiles in my application and I recently discovered the existence of the @IfProfileValue annotation which seems to provide similar functionnality . Can someone please explain what the differences are between those two annotations perhaps by providing usage examples that would contrast the two .. . Answer : As stated in the Javadoc @IfProfileValue is used to indicate that a test is enabled for a specific testing profile or environment . .. . .. . Whereas @ActiveProfiles is used to declare which active bean definition profiles should be used when loading an ApplicationContext for test classes . .. . .. . In other words you use @IfProfileValue to control whether a test class or test method will be executed or skipped and you use @ActiveProfiles to set the active bean definition profiles that will be used to load the ApplicationContext for your test . Please note that @IfProfileValue was introduced in Spring Framework 2.0 long before the notion of bean definition profiles and @ActiveProfiles was first introduced in Spring Framework 3.1 . Both annotations contain the term profile but they are actually completely unrelated The term profile is perhaps misleading when considering the semantics for @IfProfileValue . The key is to think about test groups like those in TestNG instead of profiles .

Answer : I m working on an Application using Spring MVC 4.0.4 and Hibernate and we re using Spring Test MVC 1.0.0.M2 to do some integration unit tests .

I ve got a problem with a setup that s sort of like the following : .. . .. . There are three test classes : A B C . They all use the database and are executed in that order . It s essentially this : .. . .. . Test A and C : .. . .. . Test B : .. . .. . According to the Spring documentation http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html testing-ctx-management since the ApplicationContext config of A and C are equal they share a cached ApplicationContext . B has a different context . However it still uses the same database . Here is the problem : .. . .. . Test B does some things that pollute the database causing Test C to fail . According to this Spring documentation http : docs.spring.io spring docs current spring-framework-reference html integration-testing.html testcontext-ctx-management-caching I can use the @DirtiesContext annotation to tell Spring that a test does something bad to the ApplicationContext and that Spring should re-initialize it upon next use . Putting @DirtiesContext on Test B will not work because it s not context B that should be fixed it s also that of A and C . Putting it on Test B won t make Spring re-initialize that of Test C . .. . I could put @DirtiesContext on Test A . Then when it s time to run Test C Spring will create the new ApplicationContext from scratch . However if the order of tests ever changes or we add tests with the same ApplicationContexts and they re run in between these the problem would just re-occur . All the while the order of unit integration tests really should not matter . So it s not a permanent solution and it s also not very elegant . I tried setting the hibernate.hbm2ddl.auto property to create-drop and update but since the ApplicationContext is re-created from scratch neither is the database-schema and so it doesn t help .

Let assume there is @ControllerAdvice annotated class in Spring Boot MVC . In my case it contains @ExceptionHandler annotations . Ok I can do unit-test of this class it returns formatted JSON with information from Exception class . It is easy - especially when using Spock . But what about integration tests The only way to test if my usage of Spring library is right is to create controller that only exists for testing purposes add some methods to it that eg . throw exception of specific kind and see if it returns what I designed @ControllerAdvice to return . But it seems ugly - creating additional code only for testing of existing code . So my questions is - how do You do integration-tests on @ControllerAdvice Do You just do not do it create special controller only to test @ControllerAdvice or just test it using existing controller providing it for example with wrong data that will result in exception being thrown in my case if it was @InitBinder methods we will check ModelAndView .. . Answer : For an integration test in Spring Framework the test should do the following : .. . .. . Instantiate an application context .

Context management and caching http : docs.spring.io spring docs current spring-framework-reference html testing.html testing-ctx-management .. . Context caching http : docs.spring.io spring docs current spring-framework-reference html testing.html testcontext-ctx-management-caching .. . .. . Soooo the TestContext framework certainly supports caching across tests within a test suite and I should know because I wrote it . .. . .. . Now as for why caching is not working for you I can only assume that you have configured your build framework to fork for each test or that you are running tests individually and manually within your IDE . Here s an excerpt from the last link above that might help you out : .. . .. . Test suites and forked processes .. . .. . The Spring TestContext framework stores application contexts in a static cache . This means that the context is literally stored in a static variable . In other words if tests execute in separate processes the static cache will be cleared between each test execution and this will effectively disable the caching mechanism . .. . To benefit from the caching mechanism all tests must run within the same process or test suite . This can be achieved by executing all tests as a group within an IDE . Similarly when executing tests with a build framework such as Ant Maven or Gradle it is important to make sure that the build framework does not fork between tests . For example if the forkMode for the Maven Surefire plug-in is set to always or pertest the TestContext framework will not be able to cache application contexts between test classes and the build-process will run significantly slower as a result . If you still experience issues after taking the above into consideration please consider submitting a project https : github.com spring-projects spring-framework-issues readme that demonstrates your problem . Cheers .. . .. . Sam Comment : Thanks Sam . Sumbitting a demo project is certainly a good idea as the problem seems difficult to describe . I hope I will find the time to do that .", "Question : I have a Spring MVC 3.2 project that I would like to unit integration tests . The problem is all the dependencies I have makes testing extremely difficult even with Sprint-test . I have a controller like this : .. . .. . This will return a JSON object . I would like to test this call returns a 200 and the correct object with canned JSON . However I have a lot of other classes called by those @Autowired classes and even if I mock them like this : .. . .. . this creates a lot of mocked classes . Here is how I am trying to test it : .. . .. . I can go thru and setup a H2 embeddeddatabase and populate it but I wonder if that is really a test of this controller or the application Can anyone recommend some better approaches to this integration test How does one write unit tests for controllers Thank you .. . Answer : Check out the spring show case https : github.com SpringSource spring-mvc-showcase project and take a look at controller test cases you will be able to understand and see standard way of testing controllers . MappingControllerTests.java https : github.com SpringSource spring-mvc-showcase blob master src test java org springframework samples mvc mapping MappingControllerTests.java has some json based controller testing" ] }

Answer : As far as I remember from old days that AT systems with 80286 architectures were introduced the memory consisted of 64 KB segments which is the max address that can be addressed using a 16-bit address register real-mode . Near and far jumps could happen within or outside of a segment respectively when coding was done in assembly .

In protected-mode a descriptor table could be used to extend the addressing range of the segments which could increase the amount of memory that could be utilized on a machine . Multi-tasking and also Terminate and Stay Resident TSR programs could be implemented using appropriate BIOS and OS interrupts if the code was implemented to be reentrant .

What I d like to know is how this works on assembly level . Are segments for far pointers passed on the stack Are there any special conventions .. . Answer : Most 16-bit protected-mode APIs took far pointers as parameters . A far pointer is a 32-bit value containing both a 16-bit offset low order word and a 16-bit selector high order word selectors refer to segments . It s passed by value by putting it on the stack like any other parameter . Generally these pointers could only refer a region of memory up to 65536 bytes in size but different far pointers could refer to different regions of memory allowing more than 64K of memory to be used . For example in the 16-bit Windows API Win16 the function GetClientRect https : msdn.microsoft.com en-us library windows desktop ms633503.aspx had the following documented interface : .. . .. . .. . void GetClientRect hwnd lprc .. . .. . HWND hwnd handle of window .. . RECT FAR lprc address of structure for rectangle .. . .. . .. . The symbol FAR was a macro that expanded to far keyword when using the 16-bit Windows API . Today this API function is documented as taking an LPRECT parameter which is meant to be read as being long far pointer to RECT . The symbol LPRECT is defined as a typedef of RECT in the 32-bit and 64-bit Windows APIs . It would be a typedef of RECT far when using the 16-bit API if that was still supported . There weren t separate APIs for different memory models small medium compact large because of the use of the far keyword on pointers and the function itself the API was accessible from all memory models . The compiler would see that it took a far pointer and promote any near 16-bit pointers as necessary . Comment : How were these pointers passed Is there any ABI documentation you can link me to I know that people used far pointers see my question but I d like to see some concrete examples so I can get a better understanding . Comment : Far pointers consisted of a 16-bit offset in the lower order word of the 32-bit pointer and a 16-bit selector as the higher order word . I don t know if anyone wrote up any actual ABI documentation the 16-bit calling conventions predate the term ABI I think but I ve given a 16-bit API example taken from my old Borland C++ 3.1 documentation . Comment : I actually want to know how this works on machine code level . Because that s what I need to know if I want to write such code for my own system . I know what far pointers are and how they are used on the ABI level . Your answer doesn t answer most of the questions I have e.g . how is this implemented on the ABI level and does not really add much to what I already know . Thank you for your effort though . Comment : @FUZxxl I can only answer the question you actually asked . As I said far pointers are 32-bit values . They re passed around on the stack like any other 32-bit value . If that was your question you should have just asked that . Comment : So there isn t any special convention were segments are passed in segment registers or such" ] }

It might be worth checking to see if the SDK has installed properly . In Device Manager you should see if it has the following : .. . .. . Microsoft.Kinect .. . Microsoft Kinect Audio Array Control .. . Microsoft Kinect Camera .. . Microsoft Kinect Security Control .. . .. . And : .. . .. . Sound video and game controllers .. . Kinect USB Audio .. . .. .

Kinect v1 XBOX 360 kinect Windows v1 Kinect - Kinect SDK v1.8 -VS2012+lower .. . .. . Kinect v2 XBOX ONE kinect Windows v2 Kinect - Kinect SDK v2.0 -VS2013 .. . .. . Answer 1 : Yes the XBOX360 version of the kinect will work for development purposes but it is only compatible with the Kinect SDK v1.8 . Version 2.0 SDK is specifically for the XBOX ONE kinect . Version 2 SDK has dropped all drivers for the v1 kinect and will not support it . Also note that The v2 Kinect will only work in the microsoft VS2013 or higher versions whereas the Kinect v1 will ONLY work with the VS2012 or lower versions . Be prepared to install both if necessary . I have both currently installed on my windows-8 machine . Answer 2 : Yes you can completely develop applications using the Kinect XBOX ONE 360 versions but you cannot publish them . Also the gaming versions do lack a lot of needed functionality compared to the Windows versions . I hope this post brings some clarity for Kinect developers . Good luck .", "Question : I am using a Kinect for XBOX 360 device . I installed kinectSDK v1.6 and kinect for windows support package in MATLAB 2015b .

Answer : The following tips will help you get started using your Kinect : .. . .. . 1 . If a non-Microsoft driver for the Kinect is installed on your computer the Kinect for Windows drivers might not install or function correctly . To fix this uninstall the non-Microsoft drivers before installing the Kinect for Windows SDK . 2 . Connect the power supply for the Kinect to an external power source if the Kinect has only power from the USB connection it will be minimally functional and light the LED but it must be connected to an external power source to be fully functional . 3 . No tools are required for calibration of audio and video . 4 . Your Kinect should be the only device plugged into a USB hub on your computer . If you have more than one Kinect connect them to different USB controllers . If 2 hubs are connected to the same controller only 1 Kinect can work at a time . 5 . The Kinect is protected from overheating by a fan . It is controlled by the sensor s firmware which turns off the camera at 90 degrees Celsius . There is no software interface for applications to control the fan . 6 . Reasonable lighting neither extremely dark nor extremely bright is important for capturing images with the RGB camera . Incandescent fluorescent and natural lighting provide no special obstacles but do not point an intense or constant light source at the camera because this can blind the RGB sensor . 7 . The depth sensor functions adequately in typical and reduced lighting although in near darkness there is increased noise in the signal . 8 . The depth sensor reads depth information from reflected light . Objects that are highly reflective mirrors and shiny metal or highly absorptive fluffy and or dark materials may not be registered by the depth sensor as successfully as other objects . for detailed instructions on Setting Up a Kinect Sensor please follow : https : msdn.microsoft.com en-us library hh855356", "Question : The requirement is to define a rectangle around each eye in 3D space .

Answer : I think there is some confusion because you are using the Kinect SDK and some of the answers here regard the related SDKs System.Speech in .net and Microsoft.Speech that is distributed with a variety of Microsoft server products and the Server Speech Platform . From your comments in the other answers it seems that Kinect SDK uses the Microsoft.Speech namespace and your app must reference the Microsoft.Speech.dll that came with the Kinect SDK . Just to help clarify a few things I hope : .. . .. . System.Speech is a core .net API and a recognizer that implements it is included in Windows 7 . It is a client or desktop recognizer and can be trained for specific users and includes a dictation grammar . Microsoft.Speech is a .net API that is similar but a bit different . Recognizers that implment Microsoft.Speech are part of various Server products like UCMA http : www.microsoft.com download en details.aspx id 15417 and the Microsoft Server Speech Platform http : www.microsoft.com download en details.aspx id 27226 . As you point out Microsoft.Speech is also the API used for the Kinect recognizer . This is documented in the MSDN link Philipp Schmid mentioned in a comment Speech C How To Kinect http : msdn.microsoft.com en-us library hh855387.aspx . I have not worked with Kinect but this makes sense since the recognizer doesn t require speaker training . These resources are a bit out date because the predate Kinect but they may be helpful : .. . .. . Microsoft.Speech and System.Speech are similar but different .

To get started with .NET speech there is a very good article that was published a few years ago at http : msdn.microsoft.com en-us magazine cc163663.aspx . It is probably the best introductory article I ve found so far . It is a little out of date but very helfpul . The AppendResultKeyValue method was dropped after the beta .

How can I create a method which will always set namespace default in case no ns value is specified I have looked at almost all related questions on stackoverflow and also the proto datastore docs but couldnt find the solution . This may be a silly question or maybe its not possible to do what i am trying but since i am new to appengine and enpoints proto datastore it will be great if i can get this answer so that my progress gets unblocked . Thanks", "Question : I m working on a webapp that will allow users to authenticate using simpleauth https : code.google.com p gae-simpleauth . For now I will be supporting Google and Facebook . Other than logging in and out using webapp2 the webapp will consist of Cloud Endpoint APIs . The clients will be web Android and iOS . My questions is using Endpoints Proto Datastore can I have user required True and call endpoints.get current user to get my user from an @Model.method if the user s auth provider is Facebook or any of the other supported OAuth2 providers If it is not possible does that mean I should not have user required True and should instead get a permanent user id from the provider given the OAuth2 token and keep it in the datastore generate my own auth token for that user and then pass that token to each request EDIT : Instead of passing the auth token around would it make sense to have an authenticated user request an API token that they can pass to the API methods Would this token have to be included in the POST or GET body or can it be put in a header cookie I saw some questions elsewhere on SO regarding headers and cookies with Cloud Endpoints but it s been some time since then . This is all assuming that non-Google auth won t work . .. . Answer : This answer is not going to directly answer your question but should give you a good idea how you can implement authentication in a safe way . I ve implemented something similar recently and spent quite some time figuring out which is the best way to do authentication with Google AppEngine environment . Google supports OpenId Connect protocol . Facebook s implementation should be very similar according to Getting Started with OAuth 2.0 http : my.safaribooksonline.com book - 9781449317843 practical-openid-connect id2965494 book . I will focus more on Google s implementation as I am more familiar with it but the concepts should be very similar when using other OAuth providers . OpenId Connect will give you an id token after successfully authenticating the user . It will also give you an access token . Access token is something that should be kept a secret . Never send it over the wire . Id token on the other hand is very handy . It contains some information about your user and it s encrypted so it doesn t expose any information about the user just like that . You d have to crack the id token to find out anything about user . In the unlikely event that it gets cracked it doesn t expose anything critical about the user . What you can do you can store it as a cookie and then use it in all subsequent requests to verify it the user by checking if there s an access token that matches the id token . The only drawback is that id token is quite long - it takes around 650bytes . That would mean that every http-request carries that payload . If sending that much information is too much for your use-case you can send only first few characters maybe 12 or so and then match just the first part . The id token has can also be useful when analysing your data . It will show up when analysing http requests but will not reveal any information about the user and you can still differentiate requests that came from different users . Also on a side note don t try using AppEngine s users service as it doesn t work very well with any kind of custom authentication . Hope this gives you an idea and puts you on the right track . Comment : Thanks What I plan on doing is using a unique user id from the third party service eg the Facebook account s id or the Google account s id with a provider prefix eg google : 12345 and storing that in webapp2 s user model . I will then generate my own access tokens and only go back to the third party service when I need to re-authenticate . My biggest issue is how I can use this with cloud endpoints without having to send the access or API token in each request either in the body or as a header manually and then have to manually resolve the user in the endpoint . Comment : @Eliezer if you store it as a cookie it will be sent automatically with every http-request . You will still need to check on the server if the client with that id retrieved from cookies is authorized to make the request but this step you will have to do even if you go for google s users service as mentioned in cloud endpoints documentation - developers.google.com appengine docs python endpoints auth https : developers.google.com appengine docs python endpoints auth Comment : In java you can set up servlet-filters and do the authorization check in there . I m sure python has a similar feature . Comment : I m not 100 sure if you can access the cookie header using Endpoints Proto Datastore although if you can that would make life much easier for me . I d much rather call endpoints.get current user then have to write the code to manually check if token is valid for this user . My fallback is to use annotations to handle the auth check server-side but I d love to hear from the appengine team or someone who knows for sure if a more elegant solution exists . Comment : @eliezer The cookie is sent with every http-request . I m sure there is a way to access it . The get current user will return User object which plays very well as long as you stay in AppEngine playground you use AppEngines s authentication services . As soon as you try to do more fancy stuff i.e . integrate facebook AppEngine s users service stops being very useful . You will also have a lot more problems then benefits . Although I d be interested to hear from Google and appengine team as well on this issue .", "Question : ok so this is my first post so be gentle if I don t understand the etiquette here . my setup : .. . .. . 1 . Python google-app-engine using endpoints-proto-datastore .. . 2 . iOS endpoints Obj-C client library generator .. . .. . Background .. . .. . I ve setup a test Google cloud endpoints api and had it running pretty quickly . It works great using the test app in the iOS simulator and using Google s APIs Explorer . The API is currently open to all with no authentication . I d like to : setup an API-key or system-credential that can be used by the app to ensure it alone can access the api - with all others being refused . The method in the Google Endpoints Auth docs 1 is to create an OAuth 2.0 client ID using the Google Developers Console 2 . So I have created an ID for an Installed Application of type : iOS . So far so good . In the app the GTLService Object looks like this.. . .. . .. . On GAE I ve specified the allowed client ids and added a user check to the methods.. . .. . .. . The issue .. . .. . current user is always None so the method will always raise an exception . It appears that this is a known problem Issue 8848 : Google Cloud Enpoints get current user API doesn t fill user id 3 with no prospect of a fix soon . Options 1 . Wait until google fix Issue 8848 . Can t really we have a product to release EDIT : 15 May 2015 - Google made Issue 8848 status WontFix . 2 . I saw that it may be possible to use an API Key but while I have been able to create one - I have not found a way to enable it on the backend . I also note this method has a big hole where Google s APIs Explorer can defeat it see SO question 4 . 3 . Does the @endpoints.api Argument : auth level described here 5 provide an answer I tried using : .. . .. . @endpoints.api name demogaeapi version v1 .. . auth level endpoints.AUTH LEVEL.REQUIRED .. . scopes endpoints.EMAIL SCOPE .. . description My Demo API .. . .. . .. . But was able to use the api from the client app without using credentials . So it clearly did not add any authentication . 4 . Add a hiddenProperty to the client query holding a shared-secret key . As described by bossylobster here 6 and Carlos here 7 .

We ended up changing the architectural concept for our product and this resulted in dropping the need for endpoints . .. . Answer : An excellent question and a real problem . I solved it by having my own user database-table . The Long key I use Java is auto-generated on write and that is the value I use to uniquely identify the user from then on . Also written to that table are the Google ID provided if being called through a web page email-address and iOS id when using the iOS app while not signed-in to a Google account . When my AppEngine endpoint gets called I use information that is present in the User parameter just the authenticated email-address for signed-in clients or a separate optional iosid parameter in order to fetch my internal userid number from said table and use that from then on to uniquely identify my user . I use the same table to store other user-specific information too so it really isn t any different than trying to use current user as a primary-key other than I had to make three fields googleid email iosid indexed for lookup .", "Question : I am currently using EndpointsModel to create a RESTful API for all my models on AppEngine .

Another approach would be to strictly deal with partial objects only you could fold wraps with singledispatch and create wrapped partial objects whose attributes would be taken from the deepest func attribute . Something along the lines : .. . .. . This is slightly better since now we can get the original functions docs which before defaulted to using the partial objects doc string . This can be modified to only search if the current partial object doesn t already have the set attribute which should be slightly faster when nesting many partial objects .. . .. . .. .

Answer : There are numerous other ways you might implement the many-users-to-one-club relationship - I thought of storing a clubs repeated property in the User that references the clubs they are members of stores the key of the Club . You query on Users that satisfy the clubs property and limit the results to the page-size . Use a pattern like .. . .. . next page results User.all .filter club club key .filter key last seen key .order key .run limit page-size .. . .. . to ensure that the pages are retrieved right starting and stopping at the right place .. . .. . where last seen key next page results -1 for the next call .. . .. .

Answer : What do folks here see as the relative strengths and weaknesses of Git Mercurial and Bazaar This is a very open question bordering on flamebait . Git is fastest but all three are fast enough . Bazaar is the most flexible it has transparent read-write support for SVN repositories and cares a lot about the user-experience . Mercurial is somewhere in the middle . All three systems have lots of fanboys . I am personally a Bazaar fanboy . In considering each of them with one another and against version-control systems like SVN and Perforce what issues should be considered The former are distributed systems . The latter are centralized systems . In addition Perforce is proprietary while all the others are free as in speech http : www.gnu.org philosophy free-sw.html . Centralized versus decentralized is a much more momentous choice than any of the systems you mentioned within its category . In planning a migration from SVN to one of these distributed version-control systems what factors would you consider First lack of a good substitute for TortoiseSVN . Although Bazaar is working on their own Tortoise variant http : bazaar-vcs.org TortoiseBzr but it s not there yet as of September 2008 . Then training the key people about how using a decentralized system is going to affect their work . Finally integration with the rest of the system such as issue trackers the nightly-build system the automated test system etc .

Answer : Warning : lot of articles on VCS are quickly outdated these projects in general and Bazaar in particular are quickly evolving . I found some time ago a recent benchmark : Mercurial vs . Bazaar speedtest clone and log http : draketo.de english free-software light mercurial-vs-bazaar-speedtest-2-hg-1-1-vs-bzr-1-10 it appears Hg is still faster than Bzr . Now that s funny I have just read some threads on the Bazaar mailing list particularly comments on the PEP-374 and a yet to come switch of Emacs SC to Bzr . On the latter it looks like they wait for the next release 1.14 which will bring a big speed boost at least for their needs . On the former a contributor made a good remark : if it is fast enough for you it is OK Lot of benchmarks tend to check out a large or very large codebase history and measure network speed and such . Indeed on such cases Bzr still perform poorly but they work on it . Disk space is larger too . But hey modern disks are quite large that s probably a minor issue . Personally I use Bzr for small personal projects history is still recent so I don t care much about speed . As others point out you might want to concentrate instead on usability ease of use how it fits to your workflow if renaming is important for you if various ways of accessing remote repositories including SSH and FTP for example are important etc .

But then I haven t used DVCS yet so maybe that has something to do with it .. . Answer : The python developers recently decided to switch to Mercurial and as part of the process did some basic benchmarking of git Mercurial and Bazaar which is documented in PEP-374 http : www.python.org dev peps pep-0374 tests-impressions . An incredibly rough eye balling of the numbers they posted showed Bazaar to be 2-4x slower than either git or Mercurial in the use cases tested . That being said the message conveyed on python-dev was that all of them git Mercurial Bazaar are better than Subversion for the most part they are fast enough and the choice of Mercurial over git Bazaar was mostly based on the gut feelings of the BFDL and the attendees of PyCon2009 . Comment : Thanks . I guess bzr is still slower . Wonder why they claim it s not . Comment : Mostly they seem to be claiming that bzr will soon be just as fast though they have been claiming that for a while . I m sure during the next couple of releases over the next couple of months they will get their speed on . At which point I expect benchmarks to come pouring out of the interwebs .", "Question : I hear all this stuff about bazaar being slower than git .

But then I haven t used DVCS yet so maybe that has something to do with it .. . Answer : Bazaar is such a fast moving target and presumably so is git that any claims about performance are likely to be out of date by the time you read them . According to many sources including Wikipedia git is particularly slow http : en.wikipedia.org wiki Git 5F 28software 29 Portability on Windows because it needs its POSIX environment but that nothing beats the speed of git in its native POSIX-y Linux . This is one reason I use Bazaar - apart from personally finding it easy to use I use Windows 66 of the time and Bazaar has no performance problems on Windows . I don t doubt that git is very fast on Linux though . Again though benchmarks could be skewed by a variety of factors and may be out of date . Comment : My point about benchmarks being useless because they become out of date so quickly is even truer now than in April 2009 when I wrote this answer . Things have continued to evolve at a huge speed making any comparisons between DVCSes over a few months old pretty useless .", "Question : Most my sources are in subversion and I use Id to add revision information to those sources . Then I can easily check what sources were used e.g. . --version option shows that info . Now I m going to use bazaar and I can t find such a functionality . Is there any equivalent of svn Id in bazaar .. . Answer : Having automatically generated Id tags that show a sensible version number is impossible to do with DSCM tools like Bazaar because everybody s line of development can be different from all others . So somebody could refer to version 1.41 of a file but your version 1.41 of that file is different .

Comment : There is a page on their site about Bazaar s Unicode support : bazaar-vcs.org UnicodeSupport http : bazaar-vcs.org UnicodeSupport Comment : That page is more developers spec than user doc and it s a bit out of date . Comment : I did some basic tests of Bazaar on Windows and confirmed it could add and merge files even if they had filename characters outside the current system code page . Good stuff . I ll try the repository on a Linux box later and see if it can branch it correctly . Comment : I did some further tests of Bazaar on Windows and discovered that while the command-line works fine the GUI fails at committing changes to a file with filename characters outside the current system code page . Comment : What the name of GUI", "Question : The Big Three of distributed version-control Git Bazaar and Mercurial each treat branching fairly differently . In Bazaar for example branches are separate repos actually divergent copies of the parent repo on your file system different branches live in different directories . In Git on the other hand you can have multiple branches existing in the same repo and therefore in the same directory on your file system . Mercurial supports both behaviors http : stevelosh.com blog entry 2009 8 30 a-guide-to-branching-in-mercurial the latter with named branches http : hgbook.red-bean.com read managing-releases-and-branchy-development.html id386031 . What are the pros and cons associated with these different branching models In my mind Bazaar s approach of one branch one repo makes branching more of a pain than Git s approach e.g . to use a branch in Bazaar I have to first create the branch then cd out of my current working copy then check out the new branch like I would in SVN .

Answer : Bazaar doesn t require you to work the way you describe . I ve actually written a blog post http : oxygene.sk lukas 2009 10 working-with-branches-in-bazaar about it two days ago . You can work pretty much with only a single working tree switching between various branches and creating new branches without leaving the working tree . Useful commands for this are : checkout http : doc.bazaar-vcs.org latest en user-reference index.html checkout switch http : doc.bazaar-vcs.org latest en user-reference index.html switch branch --switch http : doc.bazaar-vcs.org latest en user-reference index.html branch . Check out the workflow http : doc.bazaar-vcs.org latest en user-guide bazaar 5Fworkflows.html documentation for Bazaar you will see that you can configure it in almost any way you want . Comment : It s good to know that Bazaar is more flexible than I thought .

Answer : Mercurial and Bazaar resemble themselves very much on the surface . They both provide basic distributed version-control as in offline commit and merging multiple branches are both written in python and are both slower than git . There are many differences once you delve into the code but for your routine day-to-day tasks they are effectively the same although Mercurial seems to have a bit more momentum . Git well is not for the uninitiated . It is much faster than both Mercurial and Bazaar and was written to manage the Linux kernel . It is the fastest of the three and it is also the most powerful of the three by quite a margin . Git s log and commit manipulation tools are unmatched . However it is also the most complicated and the most dangerous to use . It is very easy to lose a commit or ruin a repository especially if you do not understand the inner workings of git . Comment : Mercurial is really on par with Git . The performance is not big difference . But bazaar is waaaay slower than Mercurial and Git . Comment : @jpartogi - Bazaar s performance numbers have been improving much faster than its competitors so I d be cautious making that kind of assertion -- particularly with the storage refactoring that s available as preview in current releases and scheduled to become default in 2.0 .", "Question : I ve just installed the latest SonarQube 5.0.1 locally to try it out .

Answer : Take a look at the comparison made recently by the Python developers : http : wiki.python.org moin DvcsComparison . They chose Mercurial based on three important reasons : .. . .. . The choice to go with Mercurial was made for three important reasons : .. . .. . According to a small survey Python developers are more interested in using Mercurial than in Bazaar or Git . Mercurial is written in Python which is congruent with the python-dev tendency to eat their own dogfood . Mercurial is significantly faster than bzr it s slower than git though by a much smaller difference . Mercurial is easier to learn for SVN users than Bazaar . .. . from http : www.python.org dev peps pep-0374 Comment : Mozilla and Sun also uses Mercurial for the same reason . Comment : bzr is also written in Python is indeed slower than hg but by a quickly narrowing margin -- and as a user of both Bazaar and Mercurial I strongly disagree with the easier to learn assertion . Comment : They are all still evolving . I decided on Bazaar for a DCVS to start with because I thought it was easiest but not much in it and Launchpad.net . It was quite slow . Git on OSX seems fine but poor Windows support . Since Python and Google projects have now adopted it and because of TortoiseHg I m swapping to Mercurial . I think Mercurial is gaining a critical mass over Bazaar and will there . And Git will do its own thing always focussed on Posix so will never be truly dominant .", "Question : I ve been playing around with Git recently to get a grasp of distributed version-control .

Answer : I am building a jquery-mobile list view by dynamically adding list elements inside a list view using the below code . The below code works fine and it displayed the list view with the checkbox as expected .

I.e the checkbox should be selected only if the checkbox is touched and not the list item . How can I do that I created a jsfiddle .

Answer : When appending checkboxes or radio buttons to a controlgroup dynamically you deal with two jQuery Mobile widgets .checkboxradio and .controlgroup . Both should be created updated enhanced styled with jQuery Mobile CSS once new elements are added . The way to achieve this is different in latest stable versions and RC version but the methods are the same . jQuery Mobile 1.2.x - 1.3.x stable versions .. . .. . After appending checkbox radio-button to either a static or dynamic controlgroup .checkboxradio should be called first to enhance checkbox radio-button markup and then .controlgroup refresh to re-style controlgroup div .

Please let me know if anyone has faced this particular issue or have any suggestions . Thanks Comment : Experiencing the same issue on iOS . Comment : Same on Windows Phone 8 too Comment : It sounds like you need to strip back your query to see what is causing the lag . It can only be down to something using up resources . This only becomes evident on phones as they are less powerful than a dev PC . In my experience the issue is with the same bit of code being called multiple times . So it can be tricky to identify unless their is a physical evidence of the code being run multiple times eg some HTML being added multiple times . Strip your code back and build it back up piece by piece and test it on the device where you ve been seeing the issues . Comment : I tried with different logic for looping but the issue still persists . Then I came across some articles which talk abt the respose lag in JQM pages with large listviews . Seems to be an valid issue with low end phones and iPhones with older versions of iOS . Can read abt it here link http : blog.jquerymobile.com page 3 under Key Changes Comment : It Could be the 300 millisecond delay on ios devices .

The application is written in PHP and it s hosted on a Linux server . What I was wondering is whether or not it would be possible to also provide support for SFTP servers but after some quick searches on Google it seems that this is not all that simple . So the question is : What would be the best way to use SFTP from within PHP Is there a class that could also provide support for FTP as well as SFTP so that same functions could be used for both Thank you in advance for your time titel .. . Answer : Yes you can do that with cURL http : www.php.net manual en book.curl.php . To switch from FTP to SFTP all you have to do is to change protocol option form CURLPROTO FTP to CURLPROTO SFTP . cURL supports following protocols : HTTP HTTPS FTP FTPS SCP SFTP TELNET LDAP LDAPS DICT FILE TFTP . BTW . SFTP is not to be confused with FTPS . SFTP is SSH File Transfer Protocol while FTPS is FTP over SSL . Comment : Actually you don t even need to mess with CURLOPT PROTOCOLS . You can just put sftp : at the front of the hostname you pass with CURLOPT URL and cURL will automatically detect and use SFTP .", "Question : I want to use http 2 with cURL .

The error is gone and I can get data with the curl --http2 now . But the page https : http2.akamai.com tells me This browser is not HTTP 2 enabled while in chrome or directly via nghttp2 it says You are using HTTP 2 right now . I m using mac os x and installed all dependencies in the latest versions via homebrew . The curl sources 7.41 I downloaded here http : ftp.sunet.se pub www utilities curl .. . Answer : You re probably not running the newly built curl or your new curl build is using the previous libcurl install . Invoke curl --version and make sure it lists HTTP2 as supported included in Features . You also need to make sure you build curl with an TLS library version that has support for ALPN for HTTP 2 over TLS . If you build with openssl you need version 1.0.2 or later . I just tried now on https : http2.akamai.com and it says You are using HTTP 2 right now just fine when I try my curl build on it like this : .. . .. . You can view the verbose output and you should see the ALPN offer and what protocol curl and the server agree on using . Comment : Yes HTTP2 is listed as a feature . Here is the complete output : localhost : svenkeinath curl --version curl 7.41.0 x86 64-apple-darwin14.3.0 libcurl 7.41.0 OpenSSL 0.9.8zd zlib 1.2.5 nghttp2 0.7.7 Protocols : dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features : IPv6 Largefile NTLM NTLM WB SSL libz HTTP2 UnixSockets Comment : Yes : Thank you Rebuilding cURL with . configure --with-ssl usr local Cellar openssl 1.0.2a-1 did the trick .

Answer : 1 . Download curl zip .. . 2 . Extract the contents if you have downloaded the correct version you should find curl.exe .. . 3 . Place curl.exe in a folder where you keep your software e.g . D : software curl curl.exe .. . 4 .

I have the following error when I send a post request to a secure url using CURLpp http : stackoverflow.com questions 1942719 pycurl-tls-handshake-error .. . .. . Ok so according to the answer to the previous question http : stackoverflow.com questions 1942719 pycurl-tls-handshake-error I should use libcurl with openSSL .

So I should be using openSSL and not see gnuTLS . So if I try to send the very same request through curl directly with the command-line it works fine and I see on the command output the result I am expecting . So It turns out when I switch to CURLpp it uses gnuTLS instead of openSSL . Is there something I have to configure in order to specify I want openSSL with CURLpp .. . Answer : cURLpp is just a wrapper over libcURL it doesn t dictate which SSL implementation libcURL uses . Am not exactly sure how you ve come to the when I switch to CURLpp it uses gnuTLS instead of openSSL conclusion but I suspect that you have multiple libcurl.so installed the one curl uses and another that your app is using via cURLpp . As a side note the TLS fatal alert .. . received mentioned in the linked question was probably a result-of a misconfiguration on the server-side invalid servername TLS extension failure to negotiate ciphers etc .

Answer : The problem is that PayPal dropped support for SSLv3 TLS 1.0 and TLS 1.1 and now only support TLS 1.2 but the OpenSSL version cURL is built with 0.9.8o does not support TLS . At this point all you can do is hope the host can update OpenSSL cURL and PHP to a newer 1.0+ version of OpenSSL . As it stands now your cURL client doesn t speak TLS which is required by PayPal and there are no ways around it other than updating OpenSSL . Comment : The only solution is to upgrade to a newer CURL version that includes OpenSSL 1.0+ . Thanks for the advice :", "Question : With the curl command-line tool is it possible to echo print or view the request and not send it Sort of like a -n option I would like to see the request header body and anything else that s included . Is there anything else that s sent besides header body .. . Answer : A HTTP request http : www.w3.org Protocols rfc2616 rfc2616-sec5.html sec5 is constructed with a request line headers and a body . curl http : curl.haxx.se does not seem to have a flag to do a dry-run .

I m asking because there is a lot of data I need to monitor which results in me transferring close to 60GB of data per month when only about 5GB of this bandwidth is relevant . I am using PHP to process the data however I am flexible in my data-retrieval approach I can use CURL WGET fopen etc . One approach I m considering is .. . .. . Does the above mean I will only transfer 6kb from www.website.com or will fopen load www.website.com into memory meaning I will still transfer the full 50kb .. . Answer : This is more an HTTP that a CURL question in fact . As you guessed the whole page is going to be downloaded if you use fopen . No matter then if you seek at offset 5000 or not . The best way to achieve what you want would be to use a partial HTTP GET request as stated in HTML RFC http : www.w3.org Protocols rfc2616 rfc2616-sec9.html : .. . .. . The semantics of the GET method change to a partial GET if the request message includes a Range header field . A partial GET requests that only part of the entity be transferred as described in section 14.35 . The partial GET method is intended to reduce unnecessary network usage by allowing partially-retrieved entities to be completed without transferring data already held by the client . The details of partial GET requests using Ranges is described here : http : www.w3.org Protocols rfc2616 rfc2616-sec14.html sec14.35.2", "Question : I want to bulk lookup ip details at ipinfo.io http : ipinfo.io developers bulk-lookup Here is my code . cat ips.txt xargs -I curl http : ipinfo.io region .. . .. .

What you can do is replace the curl call with a script which does echo Trying url 1 curl 1 - that will allow you to see which one is failing . Comment : ips.txt is simply three single lines of three ip addresses 8.8.8.8 8.8.4.4 1.2.3.4 Comment : If I eliminate any two of the ip addresses and keep only one then the curl works fine and I get results . Comment : check your character-encoding of the TXT file and then check the character-encoding assumption of the PHP script . Both should be defined rather than assumed Comment : Thanks for the info . Probably not Cygwin issue because dealing with just text which should be universal barring any encoding issues but from what I can tell its not an encoding error it is complaining about a whole URL you are passing it Washington . But I don t see Washington in input . What about do cat -A ips.txt and update the question to include this . .. . Answer : So to summarize as a step-by step for future reference .. . .. . Running uname -A can reveal what system is being used for example revealing here it is Cygwin . This leads us to thinking about Windows vs Linux differences . One of the known differences are windows dos line endings . This can be revealed as well as with generally checking all contents of a text file with : .. . .. . Now if you find it contains M line endings as it did here it means the line endings are dos windows and not nix line endings which would show only lines ending with .. . .. . To fix this simply run .. . .. . Now if you run your original command with this fixed input file it seems CURL is happy with it and it works . Thank you as well MistaGill I learned about ipinfo.io from this post . Comment : Changing the line ending to LF worked for me I used Sublime Text", "Question : This is a follow-up to my previous question - Curl Usage on OpenVMS . So I got everything working OK on my smallish 39Mbyte file . I then changed my command file to try and deal with the proper target file which is just over 8Gig . I have 9 curl commands of the type .. . .. . Now I get the following error message on parts 4 5 and 9 - always the same parts .. . .. . At first I was thinking it was some kind of 2Gig limit on the range parameters but parts 6 and 7 work OK . Any thoughts ideas or work-arounds would be welcome . Incidentally parts 1 2 3 6 and 7 download just fine Comment : looks like a 32 64 bit issue so you better check the build to make sure you build it with the proper support .. . Answer : It looks like a 32 64 bit signed unsigned-integer problem . 3000000001 is 0xb2d05e01 and as an unsigned value fits into 32 bits interpreted as a signed 32-bit value it is -1294967295 . The offsets you use don t fit into 32-bit integers neither signed nor unsigned . From the output it is not obvious to me whether the error is in the client or the server . edit : I may have missed the curl version I just noticed that for VMS curl version 7.46 was released a couple of days ago . However I have no info on a changelog . But it may be worth to try a new client . Comment : @user2699504 To add to that : The value 4000000001 part5.zip start also overflows to a negative value . 5000000001 part6.zip start overflows to a positive value as does 6000000001 part7.zip start . 7000000001 part8.zip start and 8000000001 part9.zip start are negative . I ll go out on a limb and guess that values are being converted to 32-bit signed values without overflow checking and as long as the starting offset appears to be positive it does something .

Comment : @Micha G rny no im not bound to curl . i need a tool that can access sFTP and FTP and download files . i am running on windows . i am at the same time looking for an app that will decrypt PGP after the files are downloaded .. . Answer : OK considering that you are using Windows the most simple way to do that is to use the standard ftp tool bundled with it . I base the following solution on Windows XP hoping it ll work as well or with minor modifications on other versions . First of all you need to create a batch script file for the ftp program containing instructions for it . Name it as you want and put into it : .. . .. . The first line opens a connection to the ftp server at ftp.myftpsite.com . The two following lines specify the login and the password which ftp will ask for replace login and pass with just the login and password without any keywords . Then you use mget to get all files . Instead of the you can use any wildcard . Finally you use quit to close the ftp program without interactive prompt . If you needed to enter some directory first add a cd command before mget . It should be pretty straightforward . Finally write that file and run ftp like this : .. . .. . where -i disables interactivity asking before downloading files and -s specifies path to the script you created . .. . .. . Sadly file-transfer over SSH is not natively supported in Windows . But for that case you d probably want to use PuTTy http : www.chiark.greenend.org.uk sgtatham putty download.html tools anyway . The one of particular interest for this case would be pscp which is practically the PuTTy counter-part of the openssh scp command . The syntax is similar to copy command and it supports wildcards : .. . .. . If you authenticate using a key file you should pass it using -i path-to-key-file . If you use password -pw pass . It can also reuse sessions saved using PuTTy using the load -load your-session-name argument .

The really don t understand how it is working only on black color when passing argument QColor of different colors . I would really appreciate any help or ideas . .. .

QWidget : : paintEvent http : qt-project.org doc qt-4.8 qwidget.html paintEvent worth exploring . Other than that it is hard to say what else is wrong .

Yes I can set the colour but I cannot change it as I would have expected . Could you help Thanks : D .. . Answer : The only way to change the color of a brush is via QBrush : : setColor . The brush takes a copy of the color you specify and not a reference . Maybe you are used to other programming-languages like Java where basically everything is a reference .

Comment : Your if check is wrong since you always set Pressed to true Pressed true is an assignment . What you want is if Pressed true or simpler if Pressed .

In your comment you mentioned that the RGB component of each colour is the same and the components were basically 249 181 214 and 249 .

This allows you to use any colour for the color property so long as all components are the same and the other colours will scale automatically .

I don t know how to make colors look disabled . Comment : But you ve set custom colors to that button Why you d expect Qt to know how your colors should look when it s disabled Comment : Right - but I imagine disabled applies some sort of colorize or like you said a certain change in hue and saturation . I would like to know what that is . Comment : Well I d expect the rules to change between themes but setting custom styles explicitly overrides the defaults from the theme so you should figure out the disabled style you want too for your case . Decreasing saturation makes it look washed making the color darker or grayer makes it look disabled . Making fonts gray instead of whatever color may help too .

And this still does not answer the question : How can I get disabled style colors based on existing colors and disabled style text even for black and white text .

Sidenote : In Qt 5.6 there seems to be no method setBackgroundColor for QTreeWidgetItems only setBackground . So the solution may depend slightly on the used version of Qt .", "Question : How can I get the pressed background-color of a QPushButton Thanks in advance Comment : Welcome to Stackoverflow . Could you explain what are you trying to do It seems that getting of this color is not a good idea . May be we can find better solution of your initial problem Comment : I have a QPushButton subclass when the button is long pressed I want to draw a circle with the inverse color of the background then inside it is a check symbol with the background-color . Another option for me is to erase some portion of the circle making that portion transparent to create a check mark . Comment : What I am trying to do is an overlay circle in my button with a check shaped whole in the middle of it . It s for the checked property of the button like having a check box but I want to render it as drawing . Comment : Did you written above code in PaintEvent of you sub class Try to write it in PaintEvent and call Update function in mousePressEvent . This should give you current value for the Background Color . Comment : I have tried to use update and or repaint above setDown true but it s not getting the current value for Background color . .. . Answer : It s very difficult if not impossible to find a way to get the backgound color of a button when it s pressed because it depends on the style and it s not guaranteed that the style respects the palette . However I suggest two different approaches : .. . .. . 1 . You can set you own background-color using style sheets simpler or implement the painting of the button yourself using styles or reimplementing paintEvent . See Customizing QPushButton http : doc.qt.io qt-5 stylesheet-examples.html customizing-qpushbutton .. . .. . 2 . To paint over the button with the inverse color you can set a composition mode to the painter in order to get the inverse color . For example : .. . .. . note that using this example the inverse color of middle grey 128 128 128 is exactly the same color .. . .. . See QPainter : : CompositionMode http : doc.qt.io qt-5 qpainter.html CompositionMode-enum", "Question : When I open a QColorPicker I click in the coloor map in the top center and select any color lets say red this color appears as black in the selected color bar bottom center . I have to move additionally the slider on the top right see red arrow enter image description here http : i.stack.imgur.com j061v.png to its top position to approach the selected color . Why is this slider not initially set to the highest value so I do not see black always Comment : Set it to the desired position yourself . Every parameter is default set to 0 I guess . .. . Answer : In the documentation it refers to the Standard Dialogs http : doc.qt.io qt-5 qtwidgets-dialogs-standarddialogs-dialog-cpp.html example : .. . .. .

Comment : Redux is an implementation of Facebook Flux . Flux is not a library or framework . It s simply a recommended architecture for web-applications . I don t see how you can compare a concrete implementation with the abstract concept that motivated it . Facebook s actual implementation of a Flux architecture is Relay and the open-source version is still in the very early stages . facebook.github.io relay https : facebook.github.io relay Comment : @CharlieMartin By FB Flux I ment applicaiton like this github.com facebook flux tree master examples https : github.com facebook flux tree master examples . My current project is written on FB Flux due FB Flux . If you want you may think as Redux architecture over FB Flux architecture . Comment : I understand now . You want to compare Facebook s example Flux implementation with Redux s Flux implementation Comment : Relay is not an implementation of Flux - Relay GraphQL is more concerned with managing data-fetching queryng with the server while Flux is mainly concerned with structuring Data flow between Client Side Data Models View Components . However there is some overlap : At Facebook we have apps built entirely using Flux entirely using Relay or with both . One pattern we see emerging is letting Relay manage the bulk of the data flow for an application but using Flux stores on the side to handle a subset of application state .. . Answer : Redux author here Redux is not that different from Flux . Overall it s the same architecture but Redux is able to cut some complexity corners by using functional composition where Flux uses callback registration . It s not fundamentally different but I find it that Redux makes certain abstractions easier or at least possible to implement that would be hard or impossible to implement in Flux . Reducer Composition .. . .. . Take for example pagination . My Flux + React Router example https : github.com gaearon flux-react-router-example handles pagination but the code for that is awful . One of the reasons it s awful is that Flux makes it unnatural to reuse functionality across stores . If two stores need to handle pagination in response to different actions they either need to inherit from a common base store bad you re locking yourself into a particular design when you use inheritance or call a function from the handler which will need to somehow operate on the Flux store s private state . The whole thing is messy although definitely in the realm of possible . On the other hand with Redux pagination is natural thanks to reducer composition . It s reducers all the way down so you can write a reducer factory that generates pagination reducers https : github.com rackt redux blob ecb1bb453a60408543f5760bba0aa4c767650ba2 examples real-world reducers paginate.js and then use it in your reducer tree https : github.com rackt redux blob ecb1bb453a60408543f5760bba0aa4c767650ba2 examples real-world reducers index.js L29-L46 . The key to why it s so easy is because in Flux stores are flat but in Redux reducers can be nested via functional composition just like React components can be nested . .. . .. . This pattern also enables wonderful features like no-user-code undo-redo https : github.com omnidan redux-undo . Can you imagine plugging Undo Redo into a Flux app being two lines-of-code Hardly . With Redux it is again thanks to reducer composition pattern . I need to highlight there s nothing new about it this is the pattern pioneered and described in detail in Elm Architecture https : github.com evancz elm-architecture-tutorial which was itself influenced by Flux . Server Rendering .. . .. . People have been rendering on the server fine with Flux but seeing that we have 20 Flux libraries each attempting to make server rendering easier perhaps Flux has some rough edges on the server . The truth is Facebook doesn t do much server rendering so they haven t been very concerned about it and rely on the ecosystem to make it easier . In traditional Flux stores are singletons . This means it s hard to separate the data for different requests on the server . Not impossible but hard . This is why most Flux libraries as well as the new Flux Utils https : facebook.github.io flux docs flux-utils.html now suggest you use classes instead of singletons so you can instantiate stores per request . There are still the following problems that you need to solve in Flux either yourself or with the help of your favorite Flux library such as Flummox https : github.com acdlite flummox or Alt https : github.com goatslacker alt : .. . .. . If stores are classes how do I create and destroy them with dispatcher per request When do I register stores How do I hydrate the data from the stores and later rehydrate it on the client Do I need to implement special methods for this Admittedly Flux frameworks not vanilla Flux have solutions to these problems but I find them overcomplicated . For example Flummox asks you to implement serialize and deserialize in your stores http : acdlite.github.io flummox docs api store . Alt solves this nicer by providing takeSnapshot http : alt.js.org docs takeSnapshot that automatically serializes your state in a JSON tree . Redux just goes further : since there is just a single store managed by many reducers you don t need any special API to manage the re hydration . You don t need to flush or hydrate stores there s just a single store and you can read its current state or create a new store with a new state . Each request gets a separate store instance . Read more about server rendering with Redux . http : rackt.github.io redux docs recipes ServerRendering.html .. . .. . Again this is a case of something possible both in Flux and Redux but Flux libraries solve this problem by introducing a ton of API and conventions and Redux doesn t even have to solve it because it doesn t have that problem in the first place thanks to conceptual simplicity . Developer Experience .. . .. . I didn t actually intend Redux to become a popular Flux library I wrote it as I was working on my ReactEurope talk on hot reloading with time travel http : youtube.com watch v xsSnOQynTHs . I had one main objective : make it possible to change reducer code on the fly or even change the past by crossing out actions and see the state being recalculated . .. . .. . https : camo.githubusercontent.com a0d66cf145fe35cbe5fb341494b04f277d5d85dd 687474703a2f2f692e696d6775722e636f6d2f4a34476557304d2e676966 .. . .. . I haven t seen a single Flux library that is able to do this . React Hot Loader also doesn t let you do this in fact it breaks if you edit Flux stores because it doesn t know what to do with them . When Redux needs to reload the reducer code it calls replaceReducer http : rackt.github.io redux docs api Store.html replaceReducer and the app runs with the new code . In Flux data and functions are entangled in Flux stores so you can t just replace the functions . Moreover you d have to somehow re-register the new versions with the Dispatcher something Redux doesn t even have . Ecosystem .. . .. . Redux has a rich and fast-growing ecosystem https : github.com xgrommx awesome-redux . This is because it provides a few extension points such as middleware http : rackt.github.io redux docs advanced Middleware.html . It was designed with use cases such as logging https : github.com fcomb redux-logger support for Promises https : github.com acdlite redux-promise Observables https : github.com acdlite redux-rx routing https : github.com rackt redux-router immutability dev checks https : github.com leoasis redux-immutable-state-invariant persistence https : github.com elgerlambert redux-localstorage etc in mind . Not all of these will turn out to be useful but it s nice to have access to a set of tools that can be easily combined to work together . Simplicity .. . .. . Redux preserves all the benefits of Flux recording and replaying of actions unidirectional data flow dependent mutations and adds new benefits easy undo-redo hot reloading without introducing Dispatcher and store registration . Keeping it simple is important because it keeps you sane while you implement higher-level abstractions . Unlike most Flux libraries Redux API surface is tiny . If you remove the developer warnings comments and sanity checks it s 99 lines https : gist.github.com gaearon ffd88b0e4f00b22c3159 . There is no tricky async code to debug . You can actually read it and understand all of Redux . .. . .. . See also my answer on downsides of using Redux compared to Flux http : stackoverflow.com a 32916602 458193 .

Once I saw redux I was sold . There are some portions I kept purely flux tho but man your lib is awesome", "Question : I don t understand why do we need Flux with React as React itself let s us main state of the application . Every component has a initial state and the state can be changed by user actions or any other asynchronous JavaScript . Why is React called as only a view library when it can let s us define state of the application and also update view whenever state changes . This is not what a view does....its what complete MVC does right For example : here https : facebook.github.io react is an Todo app build only with React and here http : fluxxor.com guides quick-start.html is an Todo app build with Flux and React . If we can build the Todo app with React only then why do we need Flux .. . Answer : You don t NEED Flux the same you don t need MVC . They are both architectures and you can of course build something without using either . Would you build a non-MVC app in 2016 Probably not that doesn t mean that people didn t do it in the past . Flux is awesome But as most things in the tech industry is not always the right decision things vary in a project requirement basis . Probably the biggest selling point of Flux is that it tries to enforce the data flow in one direction this means that you know for sure where the data is coming from . In a non-flux app the data for a component could be an own property a property passed down the component tree a local state variable a state variable result-of calling an API . With Flux : where does the data come from . Answer : from the stores . Redux takes this further and only uses a single store . Flux has been criticized because you need a lot of boilerplate code but again is a matter of tradeoffs . At the end is always your call depending on your project needs . Comment : Why is React called as a view library even if it can handle application state Comment : Because it was conceived to only display data . The data can change over time and facebook needed a way to render that changing data efficiently so the purpose of the state was to track those changes . Not for you to have an entire database like structure Comment : Besides it doesn t enforce how you manage your data Backbone collections localstorage local state etc the react component itself is interested in rendering your data not how that data ended up there . Comment : Agreed . Another point here is maintenance . Though initially I felt the same . But as my project grew in size components in numbers I realized importance of flux .

FLUX", "Question : I m creating a react.js application with flux architecture and I am trying figure out where and when a request for data from the server should be made . Is there a any example for this . Not TODO app .. . Answer : You can call for data in either the action creators or the stores . The important thing is to not handle the response directly but to create an action in the error success callback . Handling the response directly in the store leads to a more brittle design . Comment : Can you explain this in more details please Say i need to make initial data loading from the server . In the controller view i start an action INIT and the Store starts it s async initialization reflecting to this action . Now i would go with the idea that when the Store fetched the data it would simply emit change but not start an action . So emitting a change after initialization tells the views that they can get the data from the store . Why is there a need not to emit a change upon successful loading but starting another action Thanks Comment : Fisherwebdev about stores calling for data by doing so don t you break the Flux paradigm the only 2 proper ways i can think of to call for data is by using : 1 . use a bootstrap class using Actions to load data 2 . Views again using Actions to load data Comment : Calling for data is not the same thing as receiving data . @Jim-Y : you should only emit change once the data in the store has actually changed . Yotam : No calling for data in the store does not break the paradigm . Data should only be received through actions so that all the stores may be informed by any new data entering the application . So we can call for data in a store but when the response comes back we need to create a new action instead of handling it directly . This keeps the application flexible and resilient to new feature development .", "Question : I don t understand why do we need Flux with React as React itself let s us main state of the application .

If we can build the Todo app with React only then why do we need Flux .. . Answer : In theory you don t need flux . In small applications you don t need flux for sure . But what if your application consist of hundreds components And one of your component is form . User populate this form and you send its content to server . And get response from server with new data . And assume that this response data and data from form are necessary to other components . 1 . Without flux : You can move your data to root component and then distribute it down to all components . But if you need to distribute data from many other components too This makes your application very complex . 2 . with flux : You move your data to stores and all components which are interested about this data can get it from there . You have better control on your application and source data . I prefer redux only one store and one source of truth .. . .. . edit : .. . .. . Why is React called as a view library even if it can handle application state MVC is a software architectural pattern . It divides a given software application into three interconnected parts models views controllers . If we think about react and MVC it fit as View . But this is nothing wrong . It doesn t mean that you can use it only for views . It allows you to create normal applications . But in other hand you can use it as view for other frameworks for example you can use it with angular . In other words it is very flexible library for many uses . Comment : Why is React called as a view library even if it can handle application state Comment : It seems to me that handling application state in react components is a sort of a useful side effect . If you are writing a view you need to keep some state information like visibility of elements state of radio buttons and check boxes etc . So a good view library should provide some way to do this . But once that functionality is available nobody prevents you from storing your whole application state the same way . It might be awkward but certainly possible . Comment : @MadWombat I like your explanation . Even in react page there is this React approaches building user interfaces differently by breaking them into components . This means React uses a real full featured programming language to render views . They made it very flexible possibly they even not plan to use it as full functional framework .

However I ended up directly calling web APIs for certain situations simply because Flux seemed such overkill for the job . I was wondering how others might have solved such problem in a Flux way . enter image description here http : i.stack.imgur.com PhLq7.png .. . .. . As the diagram suggests we created the Action via the Action Creator for all Web API calls . I will give an example scenario . Let s say there are 3 components that are interested in User Store changes at the moment . User clicks one of them to load a list of user s hobbies from the back-end . But I only want only that one particular UI component to display the list of hobbies due to the user s action . The other 2 components won t change at all . Traditionally this would have been a simple couple lines asynch call with a callback . If you are to religiously follow Flux for this .. . .. . 1 . You create an action via Action Creator with a specific reference ID .. . 2 . Fetch data via Web API .. . 3 . Upon receiving data action is created using the Action Creator .. . 4 . User store listens to this result arriving via the action .. . 5 . Update the store .. . 6 . Fire store updated event all 3 components react to that and check if that was for mine using the reference ID .. . 7 . then finally render with the data fetched in that 1 UI component .. . .. . My app having many small parts that load data dynamically like this per user action I decided to use Flux for things that many components have to share states with since the stores act as centralized state provider . How do you guys use Flux to do simple data fetches such as the one mentioned above .. . Answer : There are couple of ways to solve this . 1 . Let all the components receive the update and the component decide whether to update or ignore the update . 2 . Split up your store and subscribe only to those which are need in the component . This approach can get messy with stores getting dependent on each other and simultaneous dispatch problem . If you haven t used any flux library redux https : github.com reactjs redux is highly recommended . It solves this by allowing the components to subscribe to part of state store tree .", "Question : I ve read this answer http : stackoverflow.com questions 32021763 what-could-be-the-downsides-of-using-redux-instead-of-flux reducing boilerplate http : rackt.github.io redux docs recipes ReducingBoilerplate.html looked at few GitHub examples and even tried redux a little bit todo apps .

Answer : You might be best starting with reading this post by Dan Abramov where he discusses various implementations of Flux and their trade-offs at the time he was writing redux : The Evolution of Flux Frameworks https : medium.com @dan abramov the-evolution-of-flux-frameworks-6c16ad26bb31 .. . .. . Secondly that motivations page you link-to does not really discuss the motivations of Redux so much as the motivations behind Flux and React . The Three Principles http : rackt.github.io redux docs introduction ThreePrinciples.html is more Redux specific though still does not deal with the implementation differences from the standard Flux architecture . Basically Flux has multiple Stores that compute state change in response to UI API interactions with components and broadcast these changes as events that components can subscribe to . In Redux there is only one Store that every component subscribes to . IMO it feels at least like Redux further simplifies and unifies the flow of data by unifying or reducing as Redux would say the flow of data back to the components - whereas Flux concentrates on unifying the other side of the data flow - view to model .", "Question : I m creating a react.js application with flux architecture and I am trying figure out where and when a request for data from the server should be made . Is there a any example for this . Not TODO app .. . Answer : I m a big proponent of putting async write operations in the action creators and async read operations in the store . The goal is to keep the store state modification code in fully synchronous action handlers this makes them simple to reason about and simple to unit test . In order to prevent multiple simultaneous requests to the same endpoint for example double-reading I ll move the actual request processing into a separate module that uses promises to prevent the multiple requests for example : .. . .. . While reads in the store involve asynchronous functions there is an important caveat that the stores don t update themselves in the async handlers but instead fire an action and only fire an action when the response arrives . Handlers for this action end up doing the actual state modification . For example a component might do : .. . .. . The store would have a method implemented perhaps something like this : Comment : Have you tried to put promises inside action payloads I find it more easy to deal with than dispatching multiple actions Comment : @SebastienLorber The big draw to flux for me is keeping all state updates in a synchronous code path and explicitly only as a result-of action dispatches so I avoid asynchrony inside the stores . Comment : @Federico It s unclear to me still what the best solution is . I ve been experimenting with this strategy for data loading combined with counting the number of outstanding async requests . Unfortunately flux is injected into stores after construction so no great way to get actions in the initialize method . You might find some good ideas from Yahoo s isomorophic flux libs this is something Fluxxor v2 should support better . Feel free to email me if you want to chat about this more . Comment : data : result should be data : data right there is no result . perhaps better to rename the data param to payload or something like that . Comment : I found this old thread https : groups.google.com forum topic reactjs jBPHH4Q-8Sc to be very helpful - in particular Bill Fisher and Jing Chen s comments . This is very close to what @BinaryMuse is proposing with the minor difference that dispatching happens in the action creator .", "Question : I was wondering how much state does really belong into the stores and not into the components I ve read at some places that really all state should live inside the stores . Would that include really component specific stuff like input values before submitting input validation if a modal is open if something has been clicked etc What are the best practices here Comment : To be honest I dont like that pattern with flux . I ve used flux before and I didn t go that deep into the store state . what I did was used flux to give data that was needed from the server actions and let that give me data . when the store has that data I can set state based off of the stores data . However trivial things like input values toggle state view for an active class open or closed modal. . those I let the component manage and not have to go through an action . It makes a ton more sense and is a good pattern .. . Answer : Keeping everything in flux stores may be benefitial for some apps . So first you should try to decide whether your app is like this . 1 . If you re not sure whether a piece of state belongs-to a flux store then it s most likely that it doesn t . 2 . You ll know when you need flux https : github.com petehunt react-howto learning-flux . And when you reach that level of understanding of whether such application architecture is appropriate for you you ll probably know the answer to your initial question as well . But of course it s nice to have some kind of specific guide maybe just a mental guide telling you when to keep state inside the component and when not to . I d go with these guides : .. . .. . Is this state purely UI-related Then you probably don t need to keep it in the store . Is this state shared anywhere else outside the component If not then don t put it in the store . It s fine inside the component . Can this state be persisted in the URL If so then don t put it in the store put it in the url It might be a search query of an input or a currently opened tab . There may be exceptions to all of these but in general I believe this to correspond well to the original ideas of a flux app . .. . .. . P.S . Also I should say that there are a lot of talks saying that you should may keep all your UI inside an immutable state tree . That s how redux is introduced to lots of people . I think you should understand that while this is a great concept and it allows you so save replay any user interactions it is more often than not unnecessary and it s not what the main idea of Flux is about . And redux itself is a great flux tool that doesn t force you to keep all of the UI state in the stores .", "Question : In the flux webchat example application and in the README diagram it seems like the action creator should retrieve the data from the server . flux data flow http : i.stack.imgur.com VFD2M.png .. . .. . The problem I see is that no fetch might be required if the data is already in the store . The store is the only one to know so the action need to actually be dispatched . I think it s better to fetch dernormalized data when possible to minimize xhr calls . If the store is denormalized e.g . MessageStore will contain all the data it needs to render Messages . Every message look like .. . .. . The store might have the responsability through events to update the UserStore with the partial user models . Another way I think of is to have some normalized stores and create a specific stores with a schema the view expects . In this situation it seems to me the action creator is only useful to dispatch the payload ie . it s useless . What do you think .. . Answer : I usually have my store dealing with fetching data . Doing it this way make sure that all the logic can be managed by the store itself and you have total control on when how why you fetch data . The fact that you can also have stores communicating with each other is also another pro for why the stores should be in charge of handling fetching data . Also as the Flux pattern describes : Stores contain the application state and logic . Their role is somewhat similar to a model in a traditional MVC but they manage the state of many objects. . It does make sense to have the stores managing the fetching of data from APIs server-side . Comment : thanks for answering my badly formulated question .

Individual means that the component should not associate with any store . .. . Answer : There is no right answer to this question . You could differentiate between application state and view state just as much as you could reason that all state should live in one global store . Application state could be User information product information or that type of data whereas view state could be related to toggling a div or what color a link should have depending on the application state . These two approaches are both used in the wild and there is just a matter of preference . This is a good read http : blog.elsdoerfer.name 2014 12 25 react-js-flux-om-i-am-trying-to-think-it-through that argues for the case of a single state . I won t link-to the other reasoning as it s the flux way and an easy Google Comment : Thanks for the answer . For my understanding from this Application state more like a business involved behavior state and view state is like a component user-interface behavior state . Plus normally the Application state is putted in the flux store while the view state often put in the component it self is this right Comment : Exactly - That s one way of reasoning about it : Comment : Cool this is also what I m doing till now .", "Question : I just recently discovered Redux https : github.com rackt redux . It all looks good . Is there any downsides gotcha or compromises from using Redux instead of Flux Thanks .. . Answer : One of the largest benefits in using Redux over the other Flux alternatives is its ability to reorient your thinking towards a more functional approach .

Modules in the Store category include : .. . .. . To be clear the question is how do the dependency calls map to the arrows In particular it would be helpful to see an explanation that reconciles the inconsistent correlation of arrow direction to dependency calls . Comment : The arrows represent flow of data not dependency directions . The store is not dispatching anything just registering itself to the dispatcher so it can react to actions . I highly recommend looking at redux . it s simple elegant flux without the dispatcher part redux.js.org http : redux.js.org Comment : @azium thanks for the quick feedback . Any quick thoughts on how redux overhead and learning curve compares to flux Amount of refactoring to migrate an application from flux to redux Comment : Redux learning curve is far more lenient than the original flux pattern that FB put out there they use Redux now . Fewer things to know about less code to write easier mental model . Migrations can be a pain kinda depends on how far in your are I guess . I would do the redux tutorial and feel out the migration pain yourself . There might not be any", "Question : null .. .

Any help would be much appreciated Details .. . .. . I am writing fixtures to test a multi-threaded C application .NETv4 using FitNesse v20150814 and Fitsharp v2.2.4498.25493 . In the ViewModel the background worker is setup as follows : .. . .. . Then during the user interaction the worker is kicked off with : .. . .. . In interactive mode this works fine with the event handlers being called as expected . However when I initiate the Run command using a FitNesse fixture only the DoWorkEventHandler is called as expected . The other handlers ProgressChanged RunWorkerCompleted are not called until the very end of the test when presumably the FitSharp thread is also completing . As critical work is node by those other handlers I am not able to test the outcome of the background worker s work . A colleague suggested re-structuring the application so that all the work is done in the DoWork event handler and that can work but I really don t want to go re-working the application if I can avoid it . .. . .. . Additional information .. . .. . I analyzed the threads and the call stack and have drawn a diagram to show what appears to be going on .

I can post more details if requested and apologies for the cramming in the threads image but I could only post 2 links.. . .. . Answer : You ll need some way to tell fitSharp to wait until your background worker is finished before continuing with the next step in your test script . The wait until keyword can help do this . See http : fitsharp.github.io Fit WaitUntilKeyword.html for details . You ll need a fixture method that can detect when the background worker is finished . e.g . wait until was added in fitSharp version 2.3 Comment : Thanks for your response Mike but I don t think that is my problem . Please check out the Additional Information section I just added above . Comment : I should add for clarity that I already have a wait loop in my fixture and that does work for the initial DoWork event - just not the later events as described in my additional info above . Comment : I still think my explanation is correct . There s nothing to stop the fitsharp thread from running to completion - and that s exactly what your thread information shows . The fitsharp thread needs something to make it wait for the background worker thread to complete . Comment : Sorry Mike . I have confused us both.. . The sequence-diagram shows what happens if I do not wait . If I DO wait then the script never advances past the wait loop because the event handlers after DoWork are never called . If I then use the debugger to move out of the wait loop then the later event handlers will fire but always after the fitsharp script is finished . Comment : OK .

I have several working Fitnesse tests which insert data in a database then test my full MVC application stack . When I try to add 2 Component property mappings to my entity map I get an error saying Unable to find assembly FluentNHibernate .. . which seems somewhat cryptic . All of this is being run through Fitnesse so this could be an issue with how Fitnesse loads dependencies.. . I have no idea of knowing for sure though . The only thing I know is that this code runs fine until I add the 2 Component mappings . On top of that those mappings run fine when this code is run through the normal web application so I know the Component mapping and SessionFactory class works outside of Tests project .

Answer : Try putting the DLLs that the test is looking for in the same folder as the fitsharp Runner.exe . One problem that I ran into is that .NET run-time dependencies that are defined in app.config are resolved from the directory in which the process is executed from which in this case is probably the directory where fitsharp resides .

Script for calling : .. . .. . I need something similar but for answering calls . Can t find any useful command in CLI manager show command .. . .. . Halp me plox .. . Answer : You can t answer a call directly via AMI . This is because a new call will arrive at the given context priority extension configured in the dialplan or it will be rejected if cant find one that applies . So whatever happens with that call will start at the given context priority extension in the dialplan . If you want to handle calls via AMI try using asynchronous AGI like this : .. . .. . This will handle all calls to any extension that has at least 1 digit by issuing an event AsyncAGI that you can handle with your AMI client . Then from your AMI client you can send AGIAction s like : .. . .. . This will effectively allow you to run AGI commands and handle a call like you would normally do in any AGI script from your AMI client .

In this case you say or I m guessing : you are using the context from-internal . So put those lines into that context that is anywhere between from-internal and the next section . If this is a production box I suggest you to not modified it but try it on a dev box so you dont break anything . The lines I wrote in the answer will apply to incoming calls to an extension with at least 1 digit so you might want to modified it to apply to a specific not-in-use extension like 555" ] }

Answer : Yes if you want grouping over the whole index you need the field collapsing http : wiki.apache.org solr FieldCollapsing feature .

Can anyone point me to the right direction where to find the missing components Best regards and thanks in advance Tobi .. . Answer : Solr field collapsing https : issues.apache.org jira browse SOLR-236 was released as a part of stable release 3.3 .. . So you can use the latest 3.4 Solr stable build which should have the components included with it . As well it does not require any special components to be included . Passing group true group.field some field should have it working without any changes . Comment : Thank you for this hint . I checked both version 3.3 and 3.4 . Neither in 3.4 nor in 3.3 the mentioned CollapseComponent class is available inside the core jar file . On the lucene part of the solr distribution the lucene-grouping-xxx.jar is available but not the solr grouping components . Any other ideas Comment : grouping does not need any additional components . So you can get started without any configuration changes just by passing additional query parameters . The classes for grouping have been distributed between Solr and lucene artifacts . Comment : Hmm ok the grouping should work out of the box with Solr 3.4 . I tested it and tried to collapse the filed normstufe which is configured like this and normally has content : Comment : type string indexed true stored true . The analysis of the query looks like this : webapp search path select params fl score start 0 q : group.field normstufe group true wt xml rows 20 version 2.2 hits 982 status 0 QTime 109 .

Answer : Dont think field collapsing would serve you the purpose . I can think of couple of the options - .. . .. . 1 . Generate an unique same id for the document so that when you add the new current document the old one is overwritten and you have only one version of the document always . 2 . If its possible to maintain an extra field for the documents which would indicate the status as CURRENT . Only the latest document would have the field value and you would need to reset the value for all the other version of the documents . This way you can easily filter out the latest documents by filter query and also search through all version with the filter query . Comment : 1 would make my first search scenario impossible . Regarding 2 is there a good way to mark the old document as not CURRENT when adding a new one I think I d have to reindex it . Comment : 2 handling needs to be done from the database or your source side and would surely need reindexing all the versions of the documents again . Comment : OK . It can be plan B while hoping for better options . An alternative is to index immediately to two cores one that overwrites your option 1 .

Answer : When dealing with a multi-master bi-directional scenario its not a good idea to use an auto incrementing PK . Standard practice is to create a GUID for the PK to avoid conflicts between your clients . See the following site for more details .

Someone can think that conflicts on INSERT are common problem in star-shape network with central node so SymmetricDS will implement some simple mechanism to resolve them . Maybe it can be done using IDatabaseWriterFilter 5.10.2 or using transforming data 4.8 . But I can t find out how . Comment : What database are you using Can you insert a record and specify your own PK What kind of volume of data are you working with How often will records be inserted with the same pk Sometimes you can divide up the range of the auto-increment PK and start each of your client nodes a different starting position . Depending on your db this could be as easy as inserting a record with the PK column included at the location you want that node to start incrementing . Comment : Central node is using PostgreSQL and clients are using Apache Derby . It s impossible to determine which range can one client use number of clients is unknown . In previous version of client there was very limited insufficient sync only INSERTs without foreign-keys . Collisions were solved by remapping id to new id determined by central node and new id was sent back to the client which stored it in remote id column . I suppose that database will contain lots of data in future and many collisions will happen.. .

Please help : .. . .. . definition of folded and non-folded network http : i.stack.imgur.com 8JRbL.jpg .. . Answer : Its not a particularly well explained term in that reference but all it really means is that in a folded network the network is closed - in other words subscribers can only makes calls to other subscribers of the same network . A non folded or open network means that subscribers can make calls to people outside the network being discussed . Its mostly useful as a planning tool . In real life most network are not closed or folded for obvious reasons although local exchanges might be modelled as closed or folded for planning and dimensioning purposes . Dimensioning in telecoms is very important as telecoms equipment is traditionally expensive so most networks are blocking in one way or another - i.e . they are not engineered to allow every subscriber make a call at the same time as this would be a very rare occurrence and it would be costly to have much of the equipment sitting idle at all other times .

I wonder if a phone will scan all the frequencies within the band 5 which is 869 894 for downlink or will it only scan a subset of that band . Besides is there a way to look into the cellphone to find what frequencies it scanned say via a log or the like Comment : What does this have to do with android or programming at all Comment : This is an android phone and is remotely relevant if any one knows how Android works with detecting cellular signals .. . Answer : Usually all of the frequencies present in a band are scanned to find the suitable cell . In LTE there are reference symbols which piggy pack the information required for the UE phone to decode the DL channel information and select a cell . In order to access the information regarding the frequencies it scan you have to consult the manufacturer . If it provides an interface to access those files because bands related information is logged but is only accessible by manufacturer .", "Question : Let me summarize my problem and what I would like to achieve . I have a SonyEricsson X10i phone with Android 2.3.3 . I realized that sometimes my phone not receiving calls even if it indicating full coverage . I checked myself in the MSC VLR and it indicates that I registered and my phone is currently active and also there is no IMSI DETACH flag so it should working correctly only the last Activate Date is a little bit old couple of hours which can be good as well without SMS Call Location Update as I mentioned before the phone indicates full coverage and it seems it s on the network . But when I tried to call it I only reached the Voice Mail . In the MSC VLR I see No Paging Response Cause for the call but the phone does nothing . I tried with other SW version 4.0.3 ICS but the same result . But I not noticed similar behaviour with a different handset same type . Sorry for the long summary . So because what I described above I m trying to write an application service which will perform GSM UMTS location update in 15-20 minutes but I couldn t find any kind of procedure in android.telephony.gsm.GsmCellLocation android.telephony.TelephonyManager which will do this for me . My other concern is the getState setStateOutOfService setState procedures from ServiceState class It seems they not really working . For example when I first call the getState I always get back STATE OUT OF SERVICE which is not true When I m set the state to STATE POWER OFF or STATE IN SERVICE at least I get back that state from getState afterwards but the phone does nothing for that . Not even indicate out of coverage etc .. . .. . Every suggestion comment are welcome . Comment : It does sounds like an interesting question but you made a bunch of different remarks and I can t totally understand what you want to know . As far as I understood you want to ge the location of your phone latitude-longitude as set from the cell tower triangulations is that right If it is you have to do it via the LOCATION PROVIDER and ask for the NETWORK PROVIDER . If that is not what you ask I suggest you to clarify a bit your question . Comment : Hi there basically what I want to force my phone to perform a new location update towards to the Radio Core . It s not related latitude-longitude it s pure GSM UMTS Mobility Management Signaling . link http : en.wikipedia.org wiki Mobility management . I hope clarified it if not please let me know . Comment : I guess it s clearer now but unfortunately I won t be able to help . Good luck . .. . Answer : I have also seen this problem many times 2 phones from the same manufacturer as yours . From your question I understand that you want to force the phone to send an MM periodic location update which it should be sending anyway . This is too low-level and there s nowhere you can force this directly in the programming interface . The mobility management procedure is part of the phone stack and is specified in detail in 3GPP TS 24.008 available from www.3gpp.org . Paragraph 4.2.2 defines when the phone is supposed to send these location updates . The only other thing would be to try by indirect means to force the phone into a condition where it would send a location update . You might be able to do that by trying to select another network manually . If it s successful and you then manually re-select your home network then you would trigger a location update . If it s rejected and falls back to its home network then I think a location update would be triggered as well . But there would also be small costs to this - battery use while it does a networks scan and time lost while it scans and does manual network selection . My personal experience is that the lost calls don t happen often enough to justify this . Comment : Hi thank you very much for your answer this is what I m afraid of I can t force the phone to perform a location update . At least you now confirmed it . About the workaround hmm my second thought was to put the phone to offline state and bring back to online like airplane mode but I just figured that the phone does nothing towards the core No message at all in this case just most probably not answering for the paging call sms . Sadly the problem is a little bit more crucial because it happens almost all the time when I m in the office Comment : And in case of emergency something happened with my family colleagues tries to reach me etc I not even know that I had a call. . I just got a tip from a friend that maybe I shall try to flash a new baseband firmware to my phone which is compatible with the network . I ll give a try . I thinking about another workaround which might be better than just reselect the network the application initiate a new call maybe I ll call my self : The first call attempt most probably will be dropped because of the unreachability issue but after that the phone will became online again . Comment : BTW do you know why the serviceState.getState gives back always STATE OUT OF SERVICE at the first time when I call it And force the phone to goes offline : and it s not an airplane mode Comment : The tip to update the firmware is a good one . I assume your SIM is on its home network That might make a difference . ---- Have you also tried reporting the missed calls issue to the operator Eventually you should get back to engineering support who might be able to fix it . Comment : I don t know why it returns STATE OUT OF SERVICE at the first call sorry . Might be worth a separate question .", "Question : null .. .

Answer : You could probably get this information from the chipset manufacturer s log files . Logging systems from chipset manufacturers like Qualcomm or Nvidia for example are not publically available you d have to get them from the manufacturer . Usually only customers like phone manufacturers get access . You can t get this information programmatically over the Android APIs which I assume is what you are asking - it is too low-level .", "Question : When you plug in an LTE modem as part of the attach process to the LTE network it sets up a default EPS bearer to carry signalling traffic . This default bearer is an IP connection with a Traffic Flow Template suitable for signalling traffic . The specification also allows that the network can change the TFT of the default EPS bearer so that it can carry data TS 24.301 6.4.1.1 last sentence . So if the network does set up the default EPS bearer to carry data and does not create a dedicated EPS bearer my tests show that Windows won t allow you to browse on the internet until you have set up a connection in the traditional way eg called the Mobile Broadband API Connect function in Win 7 . Here is the question : what does Windows still have to do to allow internet browsing given that an IP connection with suitable quality of service is already open Many thanks in advance for help . .. .

Here s the problem : When I make an international call from my phone on H2OWireless a reseller using the AT T GSM network the receiving end of my call gets a wrong country code transmitted as caller ID causing a number of problems . I have a US phone-number with area code 803 . If I make a call to Germany the receiver of the call sees my caller ID as 00803xxxx which does not make sense . My caller ID should be shown as +1803xxx or 001803xxx but for some reason the leading 1 gets lost . That causes the following problem : I can call regular dumb landline phones in Germany but when I try to call my bank my call bounces at their switchboard . I guess they are doing some kind of a reverse-lookup and find that +8 or +83 is not a valid country code and refuse to accept that call . I have temporarily solved the problem by having a friend setup a call forwarding for me so he forwards my call to my bank when I call him . But I would really like to understand what is going wrong here and whether AT T or Deutsche Telekom or any other provider is to blame for this problem . I would appreciate any insight from phone network experts as to how to debug the problem so that I can see who is causing this before I write a mail to either AT T support or the german provider . Comment : Have you tried a with your SIM in a phone from a different manufacturer and b a SIM from a different provider in your phone Would narrow down if the information is coming from the phone or the SIM . If one of these combinations works then as a quick solution I would probably just change whichever one is causing the problem . .. . Answer : The problem is most likely the reseller not mapping the calling number correctly - I would write the letter to them . It will be much easier for them to debug it than for you especially if they are actually obliged to do it correctly by law licence I am not sure what the rules are in the US . If it is a problem with someone else they will normally be delighted to let you know and you can then chase the guilty party instead . The reason this most commonly happens is because the reseller generally jumps off the regular network to their own IP network and they have to translate the call setup info to match the protocol they are using on their own network probably SIP based unless it is quite old . It is not uncommon for CLI data to get mixed up this way .", "Question : The problem is simple . I have an IMEI and I want to retrieve a TAC from it . How can I do it Is there a way of recognizing how many digits should TAC have if I have just an IMEI Is it necessary to know explicitly the year of production of the device to know it Comment : What solution did you use in the end .. . Answer : The first eight digits of the IMEI number is the TAC code . Prior to 2004 the first six digits were the actual device identifier and the next two were a Final Assembly Code FAC representing where the device was manufactured . Since then the FAC portion has been dropped . TAC codes are issued by two authorities CTIA for North America and the GSM Association for everywhere else identifiable by the first two digits . Because the TAC codes are issued sequentially you can test positions three through six to identify the six-digit TAC codes . For example I use code like this : .. . .. . These ranges were determined by my personal inspection of the TAC code tables and are not guaranteed .

On reception of SCRI network decides the RRC state of UE . I have some doubts in this procedure . 1 . Does the value of T323 timer is fixed for a network or it changes with adaptability 2 . Does transition from DCH to IDLE or DCH to PCH is possible in this model 3 . In android device is there any way to know the timer T323 timeout value I am new to this field so please correct me if i am wrong anywhere . Comment : I m not sure if this is a programming question . It doesn t look like it - no code . Comment : The T323 SCRI timer - FD R8 is set for a network e.g . 120s . DCH- PCH- IDLE or DCH- FACH- IDLE . Regarding access to T323 I guess it depends on your access to baseband debug logs from device . The timer values can be verified in baseband logs on other devices so it should be possible with e.g . QXDM or similar . .. . Answer : Sorry for my late response on this post.. . .. . .. . Only now I realize there s a UMTS tag in StackOverflow.. . But I think I can help in some way . First of all let me answer your question . Then I ll provide some details about it : .. . .. . 1 . Does the value of T323 timer is fixed for a network or it changes with adaptability .. . .. . This timer is set by network . It has following possible values : 0 5 10 20 30 60 90 120 seconds . I believe it does not change dynamically but network can use different values in different region or cells . 2 . Does transition from DCH to IDLE or DCH to PCH is possible in this model .. . .. . I might be wrong but I believe this is not possible . SCRI is sent by the phone . Then network move device to another state either IDLE CELL PCH or URA PCH . However I believe that SCRI is usually sent when device is in CELL FACH . So phone goes to PCH only after FACH state and not direclly from CELL DCH . 3 . In android device is there any way to know the timer T323 timeout value .. . .. . This timer is sent by network in System Information Block Type 1 message . This value is then read and handle it by Mobile Baseband Processor or Modem or CP - Communication Processor . Usually Fastdormancy feature is handled in Modem side and eventually CP logs can print T323 value . However CP Logs are not that easy to take in End-User phones . This kind of Logs are disabled on End-user software . Of course some company may want to handle FastDormancy feature in Application side and then you would be able to check via log message . However I think this is not the case.. . .. . .. . Considerations about T323 .. . .. . This timer was created to block too many SCRI messages . This timer defines how much time Mobile Phone should wait to send two consecutive SCRI messages . Below is the workflow : - Phone detects that no new packages will be sent to network . - Phone send first SCRI and start T323 timer . - Network move phone to CELL PCH or URA PCH . - Phone send some data and detects that no new data package will be sent soon . - It try to send SCRI again . However if T323 is running this SCRI is blocked . - After T323 expires SCRI is free to be sent to network and whole process start again . As you know after SCRI message is sent network moves phone to a low-power consumption state Cell PCH or URA PCH . By doing this some resources are released . If any new package need to be sent to network phone must return to CELL FACH CELL DCH and the resources must be restored . After send the data packages phone will probably send SCRI again and all resource will be released again . That s why T323 was created . To avoid resources to be released restored very often . That behavior increases signal load in a cell because resources are releases restored thru signalling messages . How Mobile Phone Detect No New Package will be sent .. . .. . This is totally a Mobile Phone Responsibility . So every Mobile Phone brand has its own algorithm or feature to detect that a SCRI can be sent . Of course you can create complicated algorithms to predict when no more data-package will be sent and avoid send unecessary SCRI . However simpler solution has been applied . Usually phone just wait sometime and if no data package was sent it tries to send a SCRI message . I hope I could help you someway . T323 causes some confusion sometimes . But it only tells how much time phone should wait before send a new SCRI - after sending the first one . It is set by network and when set to 0 phone does not wait to send SCRI . It can send whenever it want . However it is a mobile phone responsibility to decide when SCRI must be sent . Fastdormancy aim to improve battery consumption by requesting to release resources as soon as no more packages will be sent .

Can anybody please help me to understand where to use CORBA and where to use SNMP for network monitoring NMS EMS . How it interacts with OSS systems for monitoring fault and perfomance . .. . Answer : 1 . SNMP is usually used to monitor devices directly from NMS OSS point-to-point . 2 . The CORBA is usually used as so called northbound interface when you need to integrate NMS OSS with vendor specific EMS . There are protocols like TMF814 3GPP that work on top of CORBA .", "Question : BCCH Broadcast Control Channel FCCH Frequency Correction Channel .. . Answer : BCCH .. . .. . Network uses this channel to constantly broadcast messages to all device into that cell coverage . System Information messages are transmitted in this channel . Those messages carry network cell identity as well re-selection criteria neighbor cells information and several other info . It s a downlink only channel . More Info : .. . .. . http : www.rfwireless-world.com Terminology GSM-BCCH-Broadcast-Control-Channel.html .. . .. . FCCH .. . .. . In this channel network sends specific data which is used by the mobile station for synchronization purposes . Based on this change mobile can syncronize its frequency to that used by Base Station . That specific data is a all zeros burst which produces continuous sine wave which has some dependency with RF centre frequency of that cell . Due to this dependency it helps the Mobile to get synchronized with the cell . It s a downlink only channel . It is sent during BCCH Timeslot allows the mobile to synchronize its own frequency to that of the transmitting cell . SCH .. . .. . Synchronization Channel SCH is also used for synchronization purposes . However it is more related to TDMA frame structure than the frequency . This channel carries the Synchronization Channel Information . It is also send during BCCH TimeSlot . Registration Procedure .. . .. . All of those channels are Broadcast Channels .. . .. . When device is trying to acquire service from a network the first step is find the FCCH All-Zero burst . After that it can assume the position of SCH and find it as well . After finding FCCH and SCH it can now find the BCCH and receive all Broadcasted information . Comment : Thank you but is FCCH related to the Broadcast control channel FCCH adjust the mobile crystal to to the the base station but I know that this happens in the SCH the synchronization channel and it s a down link channel . Comment : Before capture the SCH devices must find the FCCH . After device detect a FCCH Burst 148 Zeros it then try to find the SCH and later the BCCH Comment : I updated the answer .

Thank you for a genuine user need input . : -", "Question : I just started reading about FI-WARE so this might be a very noob question . A beacon is basically a device that just uses bluetooth for pushing info about its position . How should it be connected to a generic Enabler for instance a a POI Data Provider an Iot Broker or a POI GE Shall it first send its coordinates to a mobile device via bluetooth and then this device is supposed to send this value to the Iot Broker If so how .. . Answer : You need base stations to listen to possible beacons coming and going nearby . A base station can very roughly approximate the distance of a nearby beacon . These base stations must know their own locations at least for POI applications . The base stations can communicate with data servers POI IoT .. . about nearby beacons . The contents of communication depends on the purpose of the system . For the FIWARE POI DP GE a base station may be directly associated to a POI and the corresponding UUID . A beacon may has its own POI record having the UUID of the beacon . When a base station detects a beacon it may update the coordinates of the beacon POI record to correspond the location of the base station itself . Supposedly we talk about this device : https : en.wikipedia.org wiki IBeacon", "Question : Does any main public FIWARE POI server exist Can I use in my application some public FIWARE POI server without creating my own one .. . Answer : A public FIWARE POI server is at http : poi.lab.fiware.org poi dp . The data is public but it is read-only for the public to keep the things simple . You can use a demo browser http : poi.lab.fiware.org pois to view the POIs on the map . There is a POI editor http : poi.lab.fiware.org pois edit poi.html for viewing detailed data but the public cannot save the modifications . Status 2016-06-09 : Populating with European POIs .. . .. . To store your own POIs it is recommended to set-up an own POI server . If you are in FIWARE FICORE etc . you might spawn a FIWARE POI instance at FIWARE Lab https : account.lab.fiware.org . Otherwise you can use the Installation guide at FIWARE POI GitHub page http : chiru.github.io FIWARE-POIDataProvider . Installation to a Ubuntu 14.04 takes about half an hour by meticuously following the detailed instructions . Outdated answer : .. . .. . As far as I know there is no supported public FIWARE POI server . There are good instructions to set up one by yourself - for private or public use .

Answer : About Fiware s Idm GE it is a bit modified openstacks identity manager . http : docs.openstack.org developer keystone It consists of keyrock and horizon which is front end application-dashboard and uses OAuth 2.0 for authorization so it would be good to look a bit at it s API . Yes you can implement login via form just send data in json format . Here is an example of that data using curl .. . .. . and get your authentication token . But the idea is to use this GE for authenticating users of multiple applications . When you register application in horizon that application is assigned client id and secret id which you pass from your application along with url of horizon and callback url via REST calls.Then user will be redirected to fiware account manager where he can log in.After successful login user is again redirected to application and in that moment you should save token in session . Regarding your first question inside horizon you can define HTTP methods users can invoke so for that group of users that can only edit POI-s you could place only GET and PUT method and for those that should create POI-s also you could add POST method .

Cause : 400 Error badRequest : message : No nw info cache associated with instance code : 400 .. . .. . Has anyone had the same problem Comment : I have problem with adding IP too . .. . Answer : Have you used the Allocate IP to project menu under the Security Tab first If you have a floating IP available it should be connected to the instance you ve created using the Associate IP -Action under the Security Floating IP s . Remember to also allocate and connect the keys and open relevant ports as described here : http : catalogue.fiware.org enablers poi-data-provider creating-instances There has been some resource floating IPs limitations in the FILAB cloud servers so this may be also the reason if you have followed all the above .", "Question : Create Blueprint Templates functionality : In the creation of a new Tier for my specific template I can t view and I can t select the POI data provider GE poi dp 3.3.3 in the right panel Software in Catalogue maybe I do something wrong Instead if I click the Open catalog button of Blueprint Templates I can see an existing template called poidataprovider with a Tier called poi dp 333 . thanks .

Comment : That is strange I just tested it and I could see the poi dp 3.3.3 on the right panel software catalog . This is the whole contents of the catalog visible to me : WebRTC SE apache2 augmentedreality 3.3.3 cep django 1.5.5 eHealth SE 1.0.0 git 1.7 marketplace 3.2.1 mediawiki 1.17.0 mongodbgonfig 2.2.3 mongodbshard 2.2.3 mongos 2.2.3 mysql 1.2.4 nodejs 0.6.15 nodejs 0.9.0 php 5.3.3 poi dp 3.3.3 postgresql 0.11.0 python 2.7.5 redis 2.4.10 repository 3.2.1 testingpuppet 1.2.3 tomcat 6 wirecloud 0.6.4 wstore 0.3.0 xml3d 3.3.3 Comment : right now if I go on the cloud portal tab fiware lab I see blank page I can not test anything : Comment : Yes it seems to be down now . According to the email I got there is a maintenance break scheduled to take place on May 7th from 8 AM to 12 AM . Hopefully it will work better after that Another option is to acquire your own virtual-server from some commercial web service provider and install all needed software there manually using the installation instructions found in the FIWARE catalog . You need this anyhow if you are targeting a commercial product at some point . Comment : thanks Timo Mukari so for a commercial scenario I cannot use fiware lab", "Question : Create Blueprint Templates functionality : In the creation of a new Tier for my specific template I can t view and I can t select the POI data provider GE poi dp 3.3.3 in the right panel Software in Catalogue maybe I do something wrong Instead if I click the Open catalog button of Blueprint Templates I can see an existing template called poidataprovider with a Tier called poi dp 333 . thanks . Antonio . .. . Answer : The ready POI image is called MiWi-POI Server you can launch it directly via the Launch button on the Images folder . If you need to use the blueprint templates the template name is poidataprovider . Select it and from the Actions menu choose Clone Blueprint . Once you have cloned it you can launch it using the Actions menu again but before that it is wise to set a proper key-pair created in the Security section to your clone by opening it by clicking the clone name and then using the Pen -icon Edit tier option and maybe also add some other software . The use of the ready image launching above is much simpler and more reliable and you need to use blueprints only if you want to install several software components . Anyhow finally you need to have your own server somewhere and install the components manually using the installation instructions for commercial permanent purposes . Comment : Thanks Timo Mukari . Comment : But if I wanted to use my specific blueprint templates why the poidataprovider is not present in the list of software in the software catalog right panel when I try to create e new Tier for my specific template in this case I must start always from blueprint existing template poidataprovider and add other requested software as new Tiers Comment : I expected to find in the list of software for a new Tier a software called poi dp 333 like the one defined for the existing poidataprovider blueprint template Comment : Good question . I have no answer to this but I will try to find out why it is not shown there . Comment : At the moment the Filab seems not to find anything in the Software in Catalogue selection it just shows Loading items.. . forever . So this could also be some Filab issue the blueprint system has not been very reliable to my experience ." ] }

For reasons unknown to us the deployment fails when deploying to the EAP 6.0 server but works perfectly fine under AS 7.1 both on our local machines and our local test-server . In short we get the following error : .. . .. . Furthermore we have the console log see below for further information . We ve found https : issues.jboss.org browse AS7-5222 and as far as we understand there is a fix included which gives more detailed error information alas we can t update upgrade at the moment . So my humble question is does anyone have an idea on how to solve this issue Updated : Here s some more log . Note that this is running OpenJDK 1.7 instead of the regular version . We ve tried both of them but the issue remains . Comment : From the log I cannot see any deployment related errors but the jboss server cannot start up properly . Comment : @Quincy The server starts just fine if there s no deployment available . The error occurs when I try to enable the deployment or from the management console or when adding the war file deployment folder . Either way it s the same issue . Comment : Porting from Jboss 7 to EAP 6 should not be hard . Have you checked if all the configuration you used in jboss 7 had been set on EAP 6 e.g . library modules Comment : I agree it should be a breeze . Yeah we ve made extensive comparisons between the configurations and the modules in order to make sure that everything is identical . Still no luck though . Comment : Hm.. . have you tried to use the full config file standalone-full.xml instead .. . Answer : We faced similar issue with JBoss AS 7.2.0 final and Spring 3.2.8 . In our case we missed the setting of spring s active profile to point to Jboss7 . Once we set this the context was resolved deployment was successful . Hope this helps .

In AS 6 it seems easier to remove the deployer whereas I have not seen any solutions for AS 7 . .. . Answer : I believe the correct approach is to use app server agnostic JAX-RS application deployment . No need to mess with any JBoss configuration . All you need is extend javax.ws.rs.core.Application http : jersey.java.net nonav apidocs latest jersey javax ws rs core Application.html in your JAX-RS web application .

Answer : As you can see here : null object in Python http : stackoverflow.com questions 3289601 null-object-in-python there is no null or undefined in Python just None .. . so you would only be able to represent undefined and null from JavaScript as None in Python . JavaScript makes a distinction between the two for its own reasons and as far as I can tell from my own experiences undefined is fairly unique to JavaScript .

Comment : the issue is irrelevant for the bounty the bounty will go to he who figures out how to conquer V8 s garbage-collection .. . Answer : It s possible to disable garbage-collection for good by changing the source code of V8 . In V8 s source edit src heap.cc and put a return statement in the beginning of Heap : : CollectGarbage .

Comment : it s an overhead but on the system-design contrary to the overhead you might be creating on maintaining a feature embedding which no one else will understand and that could give you further problems in the future . .. . Answer : What you want to do is not supported . Unlike say the CPython interpreter or even the V8 JavaScript interpreter Node.js was not designed to be embedded has no interface for doing so and no serious plan to change that . I can t find any official documentation on that but there are numerous threads like this one https : groups.google.com forum topic nodejs gJMhnTMWc Y that give the relevant information . But that doesn t mean it s impossible . The top layer of Node isn t that complicated and really you d just need to patch out a few parts of it to do different things . And in fact people have tried to do exactly that in projects like tacnode https : github.com ZECTBynmo tacnode . I don t know if any of them are ready for prime time or not but it may be worth looking at them especially if you re willing and able to contribute if they re incomplete . Of course that only gets you embedding in C or C++ you still need to embed in Python . But wrapping a C shared library so you can use it in Python well CPython and PyPy is a long-solved problem Python has had extension modules since almost the beginning as well as ctypes and cffi if you don t want to write any C code . And there are third-party projects like Cython to let you write almost-Python code that directly calls your shared library as-if it were native C and compiles to a Python extension module . So it s almost certainly doable but it s probably not going to be trivial or packaged and ready to go out of the box .", "Question : I am looking at the option of embedding node.js into python to add node.js functionality to my existing python code .

I even tried to load the jquery library before thinking maybe leaflet is dependent on it . But then I get the error .. . .. . Is there a way I can successfully load JS library .. . Answer : You can only use libraries that are not depending on the DOM since it is obviously not available server-side . One example of such a universally usable library is mustache.js . Edit : Looks like there is a way apparently leaflet s can still be useful without the DOM - one simply has to somewhat recreate DOM first as this nice fellow shows here : https : github.com rclark server-side-leaflet . Note : not sure whether this works together with PyV8 you ll have to just try . Edit2 : To extend a little bit on the previous point : What you get with PyV8 is a pure non-browser-based javascript runtime environment . It has no idea about what window or document is since V8 is not concerned about UI . Leaflet needs the DOM to operate so it needs to think it lives inside a browser . rclark s server-side leaflet needs node.js specific extensions so it won t work in PyV8 . There s this javascript DOM implementation that might work in PyV8 : https : github.com andreasgal dom.js . You d have to load all the js sources provided there into PyV8 in the right order - note that this library only provides instructions for spidermonkey not V8 . I.e . this is going to be tricky to get right . So as I see it you have the following options in order of increasing complexity and or skill required : .. . .. . 1 . Someone has apparently solved this problem for python in the following thread but apparently using some rectangular approximation using OTR - see his github link in the comments to the accepted answer . I d check this out and decide whether the approximation is good enough . Lookup country for GPS coordinates without Internet access http : stackoverflow.com questions 3643929 lookup-country-for-gps-coordinates-without-internet-access .. . 2 . Switch to a browser based environment and use leaflet directly . 3 . Switch to node.js and use rclark s port . 4 . Try to somehow get a DOM into your PyV8 possibly using andreasgal and then use leaflet from there . 5 . Adapt leaflet for your needs such that it doesn t have any DOM dependencies anymore start with shielding anything using window and or document in something like if typeof window object window null .. . .

The code above prints None presumably because the data object is not transformed to a JSArray and thus data.length evaluates to undefined . Is there a reliable way to do the necessary conversion in PyV8 other than using JSON Comment : I ve never used a global parameter this way in pyv8 . I d just write this as ctx PyV8.JSContext ctx.enter ctx.locals.data a : 1 print ctx.eval data.length Could you try this as a hello world before doing something more complex Comment : Thanks but it s not any better . ctx.locals.x a : 1 ctx.eval x.length ctx.eval x 0 .a prints None and 1 . .. . Answer : Apparently PyV8 doesn t correctly convert python lists to Javascript arrays which leads my list.length to return undefined which is getting converted to None . The answer is to use PyV8.JSArray my list . I ve written the following helper functions for my project that deal with various little problems and make it easy to convert back and forth between python and js objects . These are targeted at a specific version of PyV8 however which is the only version I can recommend see discussion in the linked issues http : stackoverflow.com questions 28416300 error-installing-pyv8-from-source-on-ubuntu 28422675 28422675 so your results may vary if you use them as-is .

Comment : Is it possible that you have some kind of infinite recursion from JS to Python and back If so you could easily run into this well before you run out of stack space recursion limit in either interpreter . Comment : @abarnert : good thinking but no this is a limited case . It s just this : - python - javascript - python - javascript . Specifically : I m running a JS script from python which calls a require python function which calls .eval on a script loaded from disk . Comment : Well I suspect you re either going to need to post an SSCCE http : sscce.org trace through the code starting in window.py or run it in a debugger because unless this is a more common problem than I think which it may well be it doesn t seem likely anyone will be able to help with just this info . Comment : @abarnert : I think you re right . I don t fully understand how PyV8 works yet which makes me less able to ask a good question.. . I ll likely figure it out in the process of asking a better question which is fine w me of course .. . Answer : What I ended up doing was protecting the entry points into javascript processing from fresh python with a threading.Lock . The require function already being in JS context bypassed this lock whereas callbacks that went back out into Python and back into JavaScript went through the lock . This seems to have done the trick for now . I wonder if that wasn t the point of PyV8.JSLocker but it didn t seem to work well using only that class for the lock.. .

Rejected - This is what happens when you reject a deferred when you throw from a .then handler or when you return a promise that unwraps to a rejection it is generally analogous to a standard exception thrown . In Angular promises resolve asynchronously and provide their guarantees by resolving via rootScope . evalAsync callback taken from here https : github.com angular angular.js blob master src ng q.js L175 . Since it is run via evalAsync we know that at least one digest cycle will happen after the promise resolves normally since it will schedule a new digest if one is not in progress . This is also why for example when you want to unit test promise code in Angular you need to run a digest loop generally on rootScope via rootScope.digest since evalAsync execution is part of the digest loop . Ok enough talk show me the code : .. . .. . Note : This shows the code paths from Angular 1.2 the code paths in Angular 1.x are all similar but in 1.3+ q has been refactored to use prototypical inheritance so this answer is not accurate in code but is in spirit for those versions . 1 When q is created it does this https : github.com angular angular.js blob master src ng q.js L173 : .. . .. . Which in turn does : .. . .. . And only resolves on nextTick passed as evalAsync inside resolve and notify : .. . .. . On the root scope evalAsync is defined as : .. . .. . Which as you can see indeed schedules a digest if we are not in one and no digest has previously been scheduled . Then it pushes the function to the asyncQueue . In turn inside digest during a cycle and before testing the watchers : .. . .. . So as we can see it runs on the asyncQueue until it s empty executing the code in your promise . So as we can see updating the scope is simply assigning to it a digest will run if it s not already running and if it is the code inside the promise run on evalAsync is called before the watchers are run . So a simple : .. . .. . Suffices keeping it simple . note angular distinguishes throws from rejections - throws are logged by default and rejections have to be logged explicitly Comment : Thanks And once again for revealing the relevant source parts I will definitely accept this answer completely perfect I feel that i can safely move on now Comment : @arty sure enjoy promises - they re truly a useful abstraction . Also it would be great if now that you understand how it works you could support this proposal : github.com angular angular.js issues 6697 https : github.com angular angular.js issues 6697 Comment : This answer explained a lot . We were using deferreds in our tests and it took quite a while for us to realise that we had to digest once until it was resolved .", "Question : I m experiencing a weird bug on IE8 while trying to catch a promise reject promise returned by a basic ngResource call : .. . .. .

Creates a promise that is resolved as rejected with the specified reason .", "Question : Given an unresolved deferred dfd and a then-able promise promise which may or may not be deferred is there a way to proxy the promise into the deferred The semantics should be as so : .. . .. . The q documentation https : code.angularjs.org 1.2.28 docs api ng service 24q only mentions handling of rejected promises and furthermore only promises rejected in a certain way : .. . .. . defered.resolve value resolves the derived promise with the value . If the value is a rejection constructed via q.reject the promise will be rejected instead . This makes it unclear if dfd.resolve promise is valid supported . Also I cannot use q.when which does take a then-able because the promise of the defered has already been returned . The Angular version is 1.2.x . .. . Answer : Yes deferred.resolve takes a promise . deferred.resolve value .. . .. . Calling resolve with a pending promise causes promise to wait on the passed promise becoming fulfilled with its fulfillment value or rejected with its rejection reason or staying pending forever if the passed promise does . Calling resolve with a rejected promise causes promise to be rejected with the passed promise s rejection reason . Calling resolve with a fulfilled promise causes promise to be fulfilled with the passed promise s fulfillment value . Calling resolve with a non-promise value causes promise to be fulfilled with that value . From the Q API Reference https : github.com kriskowal q wiki API-Reference .. . .. . To answer another part of your question : .. . .. . This makes it unclear if dfd.resolve promise is valid supported . Also I cannot use q.when which does take a then-able because the promise of the defered has already been returned . The promise created by deferred.promise can be given to more that one recipient . Each recipient can call the .then method on that promise . The promise can only be resolved once either to a value or an error . But the container can be read by more that one consumer . Think of a promise as a container for a value which you can get in the future by the .then .catch and .finally methods . You can visit the container more than once but its contents are immutable when it resolves . Deprecation of the .success and .error methods in the http service .. . .. . The AngularJS team in their new found wisdom have decided to deprecate the .success and .error methods . Those methods were buggy and I say good riddance . For more information on the deprecation or should I say failure of the .success and .error methods visit the latest AngularJS http Service API Docs https : docs.angularjs.org api ng service 24http . We should avoid the .success and .error methods and learn to use the .then .catch and .finally from now on . The q service-reference cited by the OP is dated . For the latest version visit AngularJS q Service API Docs https : docs.angularjs.org api ng service 24q . UPDATE for Legacy AngularJS v1.2 .. . .. . I did some spelunking in the AngularJS Github https : github.com angular angular.js blob v1.2.x src ng http.js L716 . The legacy http service creates a q promise L750 https : github.com angular angular.js blob v1.2.x src ng http.js L750 and subsequently attaches the buggy .success method L769 https : github.com angular angular.js blob v1.2.x src ng http.js L769 and the buggy .error method L776 https : github.com angular angular.js blob v1.2.x src ng http.js L776 . What this means is that people stuck with using the older version of AngularJS can start migrating to the .then .catch and .finally methods . An example with two consumers of the same http promise . Notice that the .then method returns data differently than the .success method . Also both consumers should check for errors . So even users of legacy AngularJS can start writing .success and .error free code . Comment : Remember q from Angular and Q by mage Kris Kowal are different albeit with confusingly similar names and the devils are in the details of the particular Promise implementation .

The call to setTimeout rather than timeout is deliberate to ensure that it must be resolve which ends up starting the digest loop . This is confirmed by looking in the source : resolve https : github.com angular angular.js blob g3 v1 2 src ng q.js L207 calls its callbacks via nextTick https : github.com angular angular.js blob g3 v1 2 src ng q.js L174 which is a function that passed the callbacks to rootScope . evalAsync which according to the evalAsync docs https : code.angularjs.org 1.2.16 docs api ng type 24rootScope.Scope 24evalAsync : .. . .. . at least one digest cycle will be performed after expression execution .. . .. .

What is the order of things that happen in each of your described steps phases .. . .. . Going into the previous example in detail : .. . .. . 1 . var d q.defer The deferred object s promise is in a pending state .

Nothing has used or affected the digest loop .. . .. . 2 . d.promise.then function scope.state Resolved and digest cycle must have run .. . .. . The promise is still in a pending state but with a then success callback registered . Again nothing has used or affected the digest loop or any scope . 3 . window.setTimeout function d.resolve 1000 .. . .. . After 1 second d.resolve will be called . This passes the callback defined in Step 2 above to evalAsync via nextTick https : github.com angular angular.js blob g3 v1 2 src ng q.js L340 . 4 . evalAsync will call the callback .. . .. . 5 . evalAsync will then ensure one digest cycle will be called . .. . .. . 2 . When new deferred object with a new promise instance created - who aware of it is it important Only the caller of q.defer .

How exactly the scope updated promise object being resolved Do i have to update it manually inside the callback or the digest will be automatically invoked and update the rootScope like declared here .. . .. . As mentioned the digest loop will be automatically started by calling resolve if it s not in it already . .. . .. . 4 . mention at least one approach of updating the scope from within the promise callback .. . .. .

Comment : Other promise implementation are much better debuggable http : stackoverflow.com questions 25827234 how-to-debug-javascript-promises .. . Answer : Unless the rejection was explicitly constructed from Error class or its child rejections can be differentiated by their types . Exceptions from q promises are handled by exceptionHandler service and logged by default https : github.com angular angular.js blob v1.5.7 src ng exceptionHandler.js L49 even if they are caught with catch .

Comment : @Uri It talks about any kind of JS errors that may happen inside Angular app callbacks except SyntaxError that cannot be caught . The question doesn t touch upon Jasmine or testing .

Is there a way to do the same for Angular deferreds or even better promises .. . Answer : The answer to your question is : yes there is a way . The other answers nicely cover the built-in limitations of q . However it s easy to add a state property to q using the provide https : docs.angularjs.org api auto object 24provide service s decorator function . Put this decorator inside of a config block and all q -instantiated deferred and promise objects will have a state property with the value pending fulfilled or rejected . Check out this plunk http : plnkr.co edit 9y5TnQFCtiHoeidxpzfO p preview .. . .. . .. . .. . Skeptical you are effectively modifying q itself wrapping every deferred with another deferred .. . .. . Actually this is not the case . q s original defer constructor is called exactly one time . It is simply decorated with additional functionality by internally attaching an event handler via then . Note that an additional defer object is instantiated as a result-of the additional then callback which is automatically created with each deferred object.. . which is to be expected because this is how angular works internally . this wouldn t work because promises shouldn t be created with deferred but chained from promises that are returned from apis .. . .. . Note that this code will decorate every deferred and thus promise object which is created by the q service . This means that any API which utilizes q will be automatically decorated with the state property . So regardless of how you use q whether with some API or on it s own this solution decorates both the deferred object and the promise and I have provided the plunk http : plnkr.co edit 9y5TnQFCtiHoeidxpzfO p preview to prove it . .. . .. . Production-worthy This approach is unit testable it s guaranteed not to break any application already using q and it s flexible in the sense that you could later add additional decorators to q without modifying the old one s .

Answer : I believe the reason your first fiddle does not work is because you are essentially binding scope property item to a promise . When you attempt to alter the value by typing into the text field angular notices the activity and then reassigns resets the value of item to the result-of the promise which hasn t changed . The solution provided by @asgoth sets assigns the value of item once when the promise is resolved .

Can you please explain to me why would that happen and more importantly what would be the way to guarantee the identical behavior using then functions .. . Answer : The .success and .error methods ignore return values . Consequently they are not suitable for chaining . On the otherhand the .then and .catch methods return a derived promise suitable for chaining from returned or throw values or from a new promise . Response Object vs Four Arguments .. . .. . Also notice that the http service provides four arguments data status headers config when it invokes the function provided to the .success and .error methods . The q service only provides one argument response to the functions provided to the .then or .catch methods .

Chaining promises .. . .. . Because calling the then method of a promise returns a new derived promise it is easily possible to create a chain of promises . It is possible to create chains of any length and since a promise can be resolved with another promise which will defer its resolution further it is possible to pause defer resolution of the promises at any point in the chain .

The objects are passed to a deferred function . I want to call the function with the next object only after the previous call is resolved . Is there any way I can do this .. . Answer : You can t use .forEach if you want to wait for a promise . Javascript and promises just don t work that way . 1 . You can chain multiple promises and make the promise infrastructure sequence them . 2 . You can iterate manually and advance the iteration only when the previous promise finishes . 3 . You can use a library like async or Bluebird that will sequence them for you . There are lots of different alternatives but .forEach will not do it for you . .. . .. . Here s an example of sequencing using chaining of promises with angular promises assuming objects is an array : .. . .. . And using standard ES6 promises this would be : .. . .. . .. . .. . Here s an example of manually sequencing assuming objects is an array though this does not report back completion or errors like the above option does : Comment : Your reduce solution is elegant but it doesn t quite work . q.defer .resolve resolves a promise but returns undefined so p is undefined for the first element . Comment : @AgDude - If you know what to suggest please propose an edit to my answer . I don t keep up with all the different proprietary promise libraries when there s an ES6 standard for all this now so if this isn t the correct way to create a resolved promise ion angularjs to start the chain then I m not sure what it should be. . Comment : elegant and clean solution Comment : the initial value q.dever .resolve did not work for me Angular 1.4.3 p was undefined on the first call . But this did work : q function resolve resolve Comment : @Artjom - In Angular 1.5.1 the doc https : docs.angularjs.org api ng service 24q resolve says that .resolve returns a promise . Perhaps this was added after 1.4.3 In any case your method works fine too . Also it needs to be q.defer .resolve - you spelled it differently in your comment . I think you could also use q.when true ." ] }

Its specification RFC 1832 http : tools.ietf.org html rfc1832.html doesn t specify any file headers or anything else beyond the encoding of various data types . The binary string you get from p.get buffer is the XDR encoding of the data you ve fed to p . There is no other kind of XDR object .

The reference of this function is here http : ps-2.kev009.com wisclibrary aix51 usr share man info en US a doc lib libs commtrf1 xdrmem create.htm . As you can see the second argument xdrs of this function is a character array . And this is similarly declared in one of the ganglia s-function as char msgbuf GANGLIA MAX MESSAGE LEN . After calling above function as xdrmem create x msgbuf GANGLIA MAX MESSAGE LEN XDR ENCODE in ganglia appropriate data in the ganglia s specific structure cb- msg is encoded to XDR format by calling the function xdr Ganglia value msg x cb- msg where x is an XDR type of variable . Later to send the encoded data through UDP channel the function Ganglia udp send message udp send channels msgbuf len is called . To understand how this XDR data is sent I tried to print the output of the content of msgbuf using fprintf but it always print nothing in spite of the fact that it is a character array . And it is also evident that the encoded data is sent successfully . So my question is How data encoded into XDR format is being sent through UDP channel here I have pasted a part of code from ganglia here http : paste.bradleygill.com index.php paste id 178644 .

Answer : The messages are encoded with XDR a binary format . The XDR libraries used are old and a modern version of the API probably would have used uint8 t instead of char . Despite it using char it is binary-data - i.e . you cannot print the data as a string . If you want to print this data use a loop where you print each byte as hex e.g . by doing printf 02X msgbuf i .. . .. . Read RFC4506 http : tools.ietf.org rfc rfc4506.txt to learn about the XDR encoding .

Answer : I m not very expert of XDR but I found a way that worked to receive data from XDR with a socket connection on TCP . First you have to do recv to receive the data from your client then call xdrmem create that need the XDR structure that you ll use to the reading a buffer a string the return-value of recv and you have to use XDR DECODE because you re writing from XDR that s codified .

I see where the second example is showing the use of XDR .

Furthermore i do not want to have to recompile the client in case i increase the packet size on my server . I would like to know if there is a proper way to send and receive this stream without having to prepend the packet size myself .

If i feed to it a correct buffer with 10 uint32 all works great . Now I tried to cut some bytes at the end of my buffer and I was expecting either xdrrec eof or xdrrec skiprecord to give me an error . This is what I wanted to use to detect that I did not have received all the data yet . What happens instead is that both return with success and the xdr uint32 t blocks the code execution . So what i now really still miss is a way to detect that i had received the full packet before start decoding it with xdr uint32 t . Any suggestion Comment : What XDR library are you using Comment : Hi I am on Linux and I simply include rpc rpc.h Comment : The packet size is irrelevant . You just have to read when the XDR library asks you to read . One of the XDR stream types deals with streams with length words in them but it s been over 20 years and I don t remember which . Comment : Are you suggesting to use xdrrec instead of xdrmem Comment : Yes it was xdr rec the one where you supply your own read and write functions . .. . Answer : The packet size is irrelevant . You just have to read when the XDR library asks you to read . The XDR xdr rec stream type deals with streams with length words in them . All you have to do is supply it with your own read and write functions . It s 22 years since I did this but it wasn t difficult . I don t understand why you think you need to receive a full packet before start ing decoding . You don t . xdr rec will call your read function as often as it needs to . The problem is that xdr uint32 t is blocking .. . .. . No . XDR functions are not blocking . Not one of them . Read the source . It is the read function that blocks . so if i have the read and the xdr uint32 t in the same thread and i run xdr uint32 t before having finished reading the whole stream .. . .. . That doesn t make sense . Read what I wrote above . You just have to read when the XDR library asks you to read . Not before . this risks to block the application . So probably i need to have the socket reading and the decoding in 2 separate threads . No . You don t seem to understand how xdr rec works . You create an xdr rec object and supply it with a read callback function and a write callback function . From there on you just call whatever XDR routines you like and they call the read or write callbacks as appropriate . You don t call them at all . There is no requirement to read the whole stream first . You should do all this in a single thread . Comment : thanks a lot . It all works now", "Question : I m trying to send chunks of data from a file using an array declared inside a structure through XDR . The idea is to establish a client-server communication encoded with XDR . I may have to use the following functions but i m not sure . If yes in which order Note : Am using C language in linux environment . Any help would be appreciated .. . Answer : You should use xdr xdrrec create providing your own read and write routines that read to write from the socket .

In C it would be and only be allowed for the last member in a strcut . .. . Answer : The most flexible solution would of course be to use the rpcgen tool to compile the XDR definition to C code which you can then compile and used in your C application . But if you do not want introduce this dependency into your project you can of course write the serialization code by hand . RFC 1831 http : tools.ietf.org html rfc1831 will give you a detailed description of how such a structure is serialize but here is what you need to know for your example : .. . .. . All number in XDR are encoded in big-endian order . All fields in a structure are aligned to 4 bytes and the fields are concatenated in the order they are declared . A float encodes a number as a 32-bit floating-point number . The variable-length array of floats is encoded as a 32-bit integer with containing the number of elements followed by the float numbers . A bool encodes a boolean value as a 32-bit integer where a true value is encoded as the number 1 and a false value is encoded as the number 0 . For example if your struct was filled with 3 floats and the value true you would get the following byte stream : .. . .. . Where the sequences of x y and z are the floating-point numbers .", "Question : I used rpcgen to generate the client and server stub for program I m developing .

Answer : I believe it is changing data when it is receiving and not sending it .

And you should look at the source code of the XDR portion of libc .", "Question : I have been looking through several websites on the Internet and actually wanted to know how do we write specification in a .x file to generate equivalent functions in .c file for RPC . Every site I visited suggested to use following kind of specification in .x file : .. . .. . So to understand practically I obtained gm protocol.x https : github.com fastly ganglia blob master lib gm protocol.x from an open-source project known as ganglia and generated equivalent C source code gm protocol xdr.c https : github.com simplegeo ganglia blob master lib gm protocol xdr.c and C header file gm protocol.h https : github.com simplegeo ganglia blob master lib gm protocol.h using rpcgen . To my surprise from what I have learned and understood gm protocol.x doesn t contain any such RPC specifications shown as code above but still it can generate too many functions in the file gm protocol xdr.c . It is pretty much sure that I am not able to understand the XDR specifications because either I have consulted wrong sources or they are outdated . I could not find any tutorial which could explain the way to generate functions Although I have found specifications to generate struct enum union etc . Please help to learn these specifications . .. . Answer : Typically from .x file you generate three groups of code : message xdr encoder decoder functions client stub and server stub well you can do it by hand as well but it s too much work to get it right . Run rpcgen with -a option too generate client-server sthus and an example implementation . Try to use a simple example first : .. . .. . The specification program is a part of RPCL but XDR language . If one puts above specifications in a test.x file and run it using rpcgen -C test.x then he she would just get .. . .. . test.h test svc.c test clnt.c .. . .. . If one doesn t need any server or client stubs and just need encoder and decoder functions of XDR then every specifications such as enum struct union etc in the file gm protocol.x would be generated into their equivalent C based declarations in gm protocol.h and their corresponding XDR encoder and decoder functions would be generated in gm protocol xdr.c which is the case specified in the question . Running rpcgen -a gm protocol.x would generate gm protocol svc.c and gm protocol clnt.c without any functions . Below are some XDR specifications : .. . .. . enter image description here http : i.stack.imgur.com u2Zmy.png .. . .. . Check the old SUN docu http : www.shrubbery.net solaris9ab SUNWdev ONCDG toc.html Comment : The link seems to be useful but this doesn t answer my question . My question is gm protocol.x doesn t contain any specification as program STLEN but still rpcgen can create gm protocol xdr.c file which contain functions . According to Unix Network Programming Vol 2 by Richard Stevens : The RPC specification RFC 1831 says that the RPC language sometimes called RPCL is identical to the XDR language which is defined in RFC 1832 except for the addition of a program definition which describes the program versions and procedures . So How are these functions created here Comment : rpcgen will generate an encoder decoder function for any struct and enum defined in the .x file.The XDR encoded message is an array of bytes and you need to convert them into corresponding types . Comment : This was what I thought earlier . So this means that there is no need of putting program STRLEN in the .x file to generate encoder decoder functions . +1 for this confirmation . I d edit your answer and add what makes the answer as complete . Thanks .", "Question : I have a C socket server who receive XDR data . I have wrote a C and a Java client . I am trying to write a Python client using xdrlib . When i decode this via the server data are different . This is because data are encoded as to be read via a xdrmem decoder . they do not have start and end of record . Does anyone know if there is a library for python who support the creation of xdr records In c this is done via xdrrec create and in Java this is called XdrTcpEncodingStream . Comment : Minimum packet length packet block size . Need create packet pattern for global use . Every packet contained a block definition . Don t communicate without header definition . Comment : sorry.. . can you rephrase your comment i did not get what you explained.. . .. . Answer : I mostly see xdrlib is the package mostly used . When you have processes that can be done in C or Java You can just run them in c java and use it in python by using and interface created by Swig . Let me know if my understanding doesn t suit the scenario . Comment : well.. . i used Swig in the past but if I use the C library xdrrec create uses different callbacks for retriving the data . I am afraid that this will not be so easy to map in python . I did not try to wrap around the Java version . If I can find a Python module that suit my needs I prefer otherwise I think I will simply stick to java to write my client or wrap the Java library in swig for python Comment : he is searching for a python-module .

But you can provide query-string parameter that will tell server this info url + format json . Of course server must react on this param otherwise it will make no sense . If you maintain your server for yourself it will be easy task . If not check if your API documentation allows you to request different content-types .

Answer : As shown elsewhere Acid3 is no test to use to determine if a browser does well with standards . In fact IE9 may not even use the canvas element which would be highly detrimental to Microsoft s attempt at making a modern browser for example . It s just as important to look at the overall compliance with web-standards and how well IE9 implements them . Right now Microsoft is comparing IE9 to current browsers and trails in several areas but IE9 won t be out in almost two years so the other browsers will be moving forward too .

Answer : Microsoft s position has been the same for a while now . They are focusing on meeting the needs of their users by attempting to fix the bugs that manifest themselves most often . Additionally they are trying to add support for the most requested features . They say in your first link As we said at MIX10 we will continue to build standards support into the IE9 platform and as a byproduct our ACID3 score will increase . and I have heard them say this elsewhere as well . They are NOT coding to the test . They are not going to attempt to fix the particular parts of the ACID 3 that are failing . Rather they are attempting to improve IE 9 as a whole by addressing the failures they see as most important . Only as a consequence of that will the ACID score improve . I think this is a good strategy . If it takes 1000 programmer-hours to fix an oddball rendering error in ACID 3 but that same amount of time could fix 2 or 3 really POPULAR bugs that ACID 3 does not address it s not designed to be comprehensive I would think their resources are better spent on those more popular bugs . Obviously what their priorities ought to be could be endlessly debated . As can the amount of success they are having . So let s not even go there . : .. . .. . Update : I d like to back up my statement that Acid 3 is not designed to be comprehensive with this citation : From http : www.webstandards.org 2008 10 02 dowehaveawinner .. . .. . Acid3 was not meant to be the one and only indication of a browser s performance . In fact many other test suites are far more important . .. . .. . and .. . .. . Many subtests are high on a developer s wish list : Full CSS 3 selectors support media-queries SVG fonts . Admittedly a few others test edge cases and more esoteric features but the test was supposed to be a significant challenge .. . .. . Although I am not an IE user it s better for us all if Microsoft sticks to improving the important stuff and skips the tests that check for esoteric features .

Answer : According to this wiki page http : en.wikipedia.org wiki Acid3 IE7 scores 14 100 whilst IE8 scores 20 100 on the Acid3 test . IE9 scores 68 100 but is currently under development . I have not read anywhere that Microsoft wants IE9 to pass the Acid test but given their track record I would say that this is not high priority for them . Let s hope I m wrong . As a comparison the latest nightly-build at the time of this writing of Firefox scores 97 100 the version of Chrome that I m using 5.0.375.29 beta scores 100 100 and Safari scores the same .

So u should change it use MOJARRA for example Comment : Yeh you re right with Mojarra it s working fine", "Question : I ve been checking around and can t find an explanation of how the FacesServlet resolves a URL to a real file in the web app file structure . Within the context of servlets my understanding is that a URL is just a made-up name that you want clients to use . In web.xml you then map specific servlets to URL patterns but the real name location of the servlet is hidden from the outside world...that s for servlets in general . Specifically for JSF 2 we deal with the FacesServlet which leads me to my first question : is the FacesServlet the only servlet I need to provide mapping details for in my app and the only servlet I need period It seems like the answer is yes but if there are situations where this wouldn t be the case please give an example . From reading other questions on SO I understand that not all requests need to pass-through the FacesServlet so basically requests are divided into A requests for static content that shouldn t be processed by the FacesServlet and B requests for dynamic-content that need to be processed by the FacesServlet . So how is the static content obtained Just by having an incoming request in which the URL doesn t match the URL pattern for the FacesServlet but does match a real file location in the app file structure .. . .. . Finally my main question : when a request comes in that matches the URL pattern for the FacesServlet how does the FacesServlet know which view file .xhtml to render Is there a convention in working with JSF 2 that I need to follow to make it work If not then I don t get it because like I mentioned above in the case of a general servlet the URL could include a name that nas nothing to do with the real file name as long as it s mapped to the correct servlet in the web.xml file . I feel like I m missing something obvious and important here . The only thing I can think of is that the URL should match a real file location or that there s another mapping table or something that associates URLs with view files . By the way I looked at this question http : stackoverflow.com questions 13284275 why-doesnt-facesservlet-find-xhtml-facelet which is related but doesn t have any answers . Thanks .. . Answer : The easiest way to serve static content is outlined in the servlet specification http : download.oracle.com otndocs jcp servlet-3.0-fr-eval-oth-JSpec section 10.5 : .. . .. . A Web application exists as a structured hierarchy of directories . The root of this hierarchy serves as the document root for files that are part of the application . For example for a Web application with the context path catalog in a Web container the index.html file at the base of the Web application hierarchy or in a JAR file inside WEB-INF lib that includes the index.html under META-INF resources directory can be served to satisfy a request from catalog index.html . If an index.html is present both in the root context and in the META-INF resources directory of a JAR file in the WEB-INF lib directory of the application then the file that is available in the root context MUST be used . The rules for matching URLs to context path are laid out in Chapter 12 Mapping Requests to Servlets . and .. . .. . A special directory exists within the application hierarchy named WEB-INF . This directory contains all things related to the application that aren t in the document root of the application . Most of the WEB-INF node is not part of the public document tree of the application . Except for static resources and JSPs packaged in the META- INF resources of a JAR file that resides in the WEB-INF lib directory no other files contained in the WEB-INF directory may be served directly to a client by the container . That is to serve static content it is sufficient to save the content in the appropriate directory of your web application . Servlet mappings are in addition to this implicit servlet . Most JSF applications therefore only declare the FacesServlet . IIRC in recent JSF implementations that servlet will even declare itself if its declaration is omitted so you don t even have to declare it explicitly . How the FacesServlet locates the definition of the view to use is defined in the JSF specification http : www.jcp.org en jsr detail id 344 in particular section 7.6.2 : .. . .. . The terms view identifier and viewId are used interchangeably below and mean the context relative-path to the web application resource that produces the view such as a JSP page or a Facelets page . In the JSP case this is a context relative-path to the jsp page representing the view such as foo.jsp . In the Facelets case this is a context relative-path to the XHTML page representing the view such as foo.xhtml . .. . JSF implementations must provide a default ViewHandler implementation along with a default ViewDeclarationLanguageFactory implementation that vends ViewDeclarationLanguage implementations designed to support the rendering of JSP pages containing JSF components and Facelets pages containing JSF components . The default implementation is specified in the following section 7.6.2.1 . I spare your the full quotation . The gist is that if the Faces Servlet is mapped with a prefix mapping e.g . faces the viewId is the part of the URL following the prefix and if the Faces Servlet is mapped with a suffix mapping e.g . .jsf the viewId is the part of the URL following the context path with replaced file extension . For instance if the servlet is mapped to .jsf a request for the URL http : host context admin userlist.jsf would read the view definition from the file admin userlist.xhtml in the web application directory . Comment : Thanks for the specs links . So if I m understanding correctly there is an implicit convention in JSF in that the viewId portion of the URL must match a real relative-path to a resource or else nothing will be found . Is this right This would make sense because otherwise I don t know how else the FacesServlet would know which facelet to return . Comment : Yes that is correct . Of course you could customize that convention or even load the view definitions from a totally different source the internal workings of JSF are quite customizable but usually one simply uses that convention . Comment : Great . Thanks for the help", "Question : I m trying to setup a small example application FooTest that uses CXF JAX-RS and JSF . I started with the CXF part implemented a simple service works and a small html page called home.html I can access it in my browser . The relevant code is as follows : .. . .. . web.xml .. . .. . FooService.java .. . .. . Now I can call http : localhost : 8080 FooTest rest foo and http : localhost : 8080 FooTest home.html . However when I start defining and mapping the FacesServlet to .html and try to access home.html I get a NullPointerException . New web.xml .. . .. . Leads to .. . .. . How can I fix this Update - More config info .. . .. . The application runs on the JAX-RS version of TomEE 1.5.2 . src main webapp WEB-INF faces-config.xml .. . .. . Update - Solution .. . .. . Thanks to David Blevins for clarification and pointing me to a useful example .. . .. . Remove the CXF configuration part it is not required . Rename home.html to home.xhtml since .xhtml is the javax.faces.DEFAULT SUFFIX for JSF pages . Keep the FacesServlet mapping if you want to access your JSF pages using the .html extension . This is sufficient : Comment : Where is your faces-config.xml located Comment : In src main webapp WEB-INF Comment : Please post faces-config.xml as well . .. . Answer : Not sure whether this should be a comment or an answer but you shouldn t setup CXFNonSpringJaxrsServlet and FacesServlet in your web.xml all that stuff is there and ready to go . The goal with TomEE is you can skip the server-building and proceed directly to app-building . CXF is fully integrated into Tomcat in TomEE to the point where even WS-Security works on Tomcat Realms . You just start using it by adding @ApplicationPath annotated components or EJBs annotated with @Path and they will be picked up and deployed automatically . MyFaces is good to go and fully integrated with CDI so even things like @ConversationScoped work out of the box . You just need your faces-config.xml or some @ManagedBean classes . Comment : Oh . I was just starting to hate CXF for its messy documentation and the configuration overhead inherited from its Spring nature . It took me some time to figure out what parts I actually need to make it work in the first place . But this is good news Just tried using an empty web.xml and now it works . I guess I have to rename my .xhtml files to .html .xhtml doesn t work but that s fine . Maybe you can explicitly mention this no-configuration-required-thing in the examples and documentation Anyway thanks a lot . Comment : I might be wrong on the JSF part the FacesServet might be needed only for the purposes of getting xhtml enabled . You can definitely do it we just added an example today that does it but shouldn t be needed for JSF in general . Help on the docs is always welcome All the pages have a little blue pencil icon in the upper right . Click that and you can edit the page and submit a kind of pull request Comment : And very glad it s working and welcome to StackOverflow : Comment : Okay I was a little too quick . My example page showed up but didn t render JSF tags . Actual solution : The CXF configuration is not required and had nothing to do with the problem which is good . The FacesServlet mapping is required when you want to acess .xhtml JSF-pages via .html . The problem with my example is that I named my page home.html but the javax.faces.DEFAULT SUFFIX is .xhtml . Unless you change the suffix you can t use .html .", "Question : null .. .

Answer : This problem suggests that you re using JSF 1.x not JSF 2.x . JSF 1.x uses JSP as default view technology whereas JSF 2.x uses Facelets as default view technology . And JSF 1.x has the known bug feature that its FacesServlet would run in an infinite-loop when it s being mapped on same suffix URL pattern as the physical view file . And indeed your WEB-INF lib contains among others the following JARs which absolutely do not belong there . GlassFish as being a full fledged Java EE container already ships with Servlet and JSF API impl out the box . javax.servlet.jar Servlet API already supplied by GlassFish jsf-api.jar Mojarra 1.x GlassFish already supplies Mojarra 2.x jsf-impl.jar Mojarra 1.x GlassFish already supplies Mojarra 2.x myfaces-api-1.1.5.jar MyFaces 1.x GlassFish already supplies Mojarra 2.x myfaces-impl-1.1.5.jar MyFaces 1.x GlassFish already supplies Mojarra 2.x Get rid of them . Even then you should not be mixing multiple JSF implementations in one webapp . Comment : Even getting the same error now Comment : Clean rebuild redeploy restart .

The obvious difference between the two is binary vs xml but it does go a lot deeper than that : .. . .. . fields BinaryFormatter bf vs public members typically properties XmlSerializer xs .. . type-metadata based bf vs contract-based xs .. . version-brittle bf vs version-tolerant xs .. . graph bf vs tree xs .. . .NET specific bf vs portable xs .. . opaque bf vs human-readable xs .. . .. . As a discussion of why BinaryFormatter can be brittle see here http : marcgravell.blogspot.com 2009 03 obfuscation-serialization-and.html . It is impossible to discuss which is bigger all the type metadata in BinaryFormatter can make it bigger . And XmlSerializer can work very with compression like gzip .

Answer : You are referring to mark a field as non serializable so I assume you are using BinaryFormatter and NonSerialized . If so the only way to do conditional serialization is by implementing ISerializable and adding a similar constructor and putting the logic in the GetObjectData implementation . This is tedious and error prone though . I would suggest looking at protobuf-net which has simpler conditional serialization using the standard patterns used by TypeDescriptor and XmlSerializer but is still binary output more efficient than BinaryFormatter actually . Specifically : .. . .. . This ShouldSerialize is a standard name-based convention - nothing specific to this serializer . Here s the same via ISerializable : .. . .. . Lots more to maintain in particular you have to take responsibility for all members when using ISerializable - however if you just use protobuf-net you can handle each on a case-by-case basis . Actually you can mix-and-match too i.e . if you are stuck with using BinaryFormatter you can still offload the work to protobuf-net but it will-change the format so won t be compatible with old data .

If you need efficient storage build your own custom serialization methods . .. . Answer : Our application operates massive data . It can take up to 1-2 GB of RAM like your game . We met same storing multiple copies of the same objects problem . Also binary-serialization stores too much meta data . When it was first implemented the serialized file took about 1-2 GB . Nowadays I managed to decrease the value - 50-100 MB . What did we do . The short answer - do not use the .Net binary-serialization create your own binary-serialization mechanism . We have own BinaryFormatter class and ISerializable interface with two methods Serialize Deserialize . Same object should not be serialized more than once . We save it s unique ID and restore the object from cache . I can share some code if you ask . EDIT : It seems you are correct . See the following code - it proves I was wrong . Looks like BinaryFormatter uses object.Equals to find same objects . Have you ever looked inside the generated files If you open temp-file0.txt and temp-file1.txt from the code example you ll see it has lots of meta data . That s why I recommended you to create your own serialization mechanism . Sorry for being cofusing . Comment : thanks - I will ultimately use XML serialization probably because human-readability is pretty important to me - but really my goal question right now is how is to understand what the BinaryFormatter class is actually storing so that I can determine whether to focus on implementing my own serialization OR address some other design issue in the data structure itself .

Answer : You seem to have some highly specific assumptions about how Boost Serialization should serialize to it s proprietary non-portable binary format . Boost serialization is much more highlevel more or less specifically designed to deal with non-POD data . If you insist you should be able to serialize an array of your POD type directly . In your question though the class is not at all POD and hence not bitwise serializable anyway . For portable archives see EOS Portable Archive .

Answer : Both of the existing answers focus on cross-platform but that is an unrelated issue . The point they are making there is don t use BinaryFormatter if you are doing cross-platform - which I entirely support . However there are a range of binary-serialization formats that are very much cross-platform - protobuf ASN.1 being prime examples . So let s look instead at what each has to offer .. . .. . Binary is typically smaller typically faster to process at both ends and not easily human-readable editable .. . Text formats xml json tend to be more verbose than binary although often compresses well but are pretty easy to work with by hand but all that text-processing an mapping tends to make them slower .. . xml is very common is web-services and benefits from gooling support such as xsd xslt and robust xml editors .. . json is the main player in browser-based comms although it is also used in web-services - tends to be less formal but still very effective .. . .. .

I want to retrieve it back but I wasn t able to type cast it . This is how i saved it . The dt is the DataTable object instance . .. . Answer : I m afraid I ll have to disappoint you at least until you tell us that you ve created an extension method for the StreamWriter class that handles data tables . The only overload of the Write method that accepts a DataTable instance is the one that takes an object and per the MSDN documentation http : msdn.microsoft.com en-us library dfc2b8zk.aspx it only saves the text representation of the object . So let s hope that the .ToString method of DataTable outputs a string in a format that contains all the contents of the DataTable instance but alas . The .ToString method only returns the contents of the TableName property http : msdn.microsoft.com en-us library system.data.datatable.tostring.aspx and a display expression if one is present . So what you ve saved is not the contents of the DataTable instance all only the name of the table .

Lots of .NET classes to this for example . You cannot recover that from the binary-data . .. . Answer : Q1 : Why is there no tool that recreates the class definition from a binary serialized file data My guess is that very few people need this . To start with binary-serialization isn t as popular as XML JSON and other formats which are standardized and are supported virtually anywhere . There s no documentation on the binary format . One needs to dig into .NET Framework sources to understand it . It s not fun . Q2 : Is there such case-when it s impossible to restore the class definition from the serialized data Looks like the binary format contains enough data . If you absolutely need a tool to reverse engineer original classes and their fields from the serializied files you can start with reading sources of System.Runtime.Serialization.Formatters.Binary.BinaryFormatter System.Runtime.Serialization.Formatters.Binary.ObjectReader and other classes from mscorlib .

Answer : All of the references to other objects will be serialized as well . If you deserialize the data you will end up with a complete working set of its data including objects A B and C . That s probably the primary benefit of binary-serialization as opposed to XML serialization . If any of the other classes your object holds a reference to are not marked with the Serializable attribute http : msdn.microsoft.com en-us library system.serializableattribute.aspx you ll get a SerializationException http : msdn.microsoft.com en-us library system.runtime.serialization.serializationexception.aspx at run-time the image of which was shamelessly stolen from the web run-time errors don t even look like this anymore in the current versions of VS : .. . .. . Example of an unhandled SerializationException http : i.stack.imgur.com 2DZkk.jpg .. . .. . Further than that I m not really sure what internal things you were hoping to understand . Serialization uses reflection http : msdn.microsoft.com en-us library f7ykdhsy.aspx to walk through the public and private fields of objects converting them to a stream of bytes which are ultimately written out to a data-stream . During deserialization the inverse happens : a stream of bytes is read in from the data-stream which is used to synthesize an exact replicate of the object along with type information . All of the fields in the object have the same values that they held before the constructor is not called when an object is deserialized . The easiest way to think about it is that you re simply taking a snapshot-in-place of the object that you can restore to its original state at will . The class that is responsible for the actual serialization and deserialization is called a formatter it always inherits from the IFormatter interface http : msdn.microsoft.com en-us library system.runtime.serialization.iformatter.aspx . It s job is to generate an object graph which is a generalized tree containing the object that is being serialized deserialized as its root . As mentioned above the formatter uses reflection to walk through this object graph serializing deserializing all object references contained by that object . The formatter is also intelligent enough to know not to serialize any object in the graph more than once . If two object references actually point to the same object this will be detected and that object will only be serialized once . This and other logic prevents entering an infinite-loop . Of course it s easy to have a good general understanding of how this process works . It s much harder to actually write the code that implements it yourself . Fortunately that s already been done for you . Part of the point of the .NET Framework is that all this complicated serialization logic is built-in leaving you free from worrying about it . I don t claim to understand all of it myself and you certainly don t need to either to take full advantage of the functionality it offers . Years of writing all that code by hand are finally over . You should be rejoicing rather than worrying about implementation details . : - Comment : Thanks Cody exactly what I was looking for .

Anyway you re welcome .", "Question : As we all know and mentioned in MSDN https : msdn.microsoft.com en-us library ms973893.aspx f 255 site : .. . .. . The serialization architecture provided with the .NET Framework correctly handles object graphs and circular references automatically . The only requirement placed on object graphs is that all objects referenced by the object that is being serialized must also be marked as Serializable . If this is not done an exception will be thrown when the serializer attempts to serialize the unmarked object . My question is why this constraint is applied If this is a constraint - Comment : It is because BinaryFormatter explicitly check presence of this attribute and throw exception if it absent . Comment : @PetSerAl That s not the question . question is why this constraint is applied If this is a constraint - Comment : Binary serialisation will serialise private fields too . This might have unintended consequences in some objects . There are some library s you can use if you need to overcome this . This isn t necessarily the answer to the question . Just a comment . .. . Answer : BinaryFormatter has very unusual powers nothing else resembles what it does . It can create an object of your class without running its constructor . And it can give a value to your properties without running the property setter accessor methods . Otherwise nothing particular magical about this it simply persists the values of the fields of your class object . And restores them when the object is deserialized . Not every class is suitable to be treated like this either because of security concerns or because field values depend on runtime state too much . Note how security is an issue since an attacker could manipulate the serialized data and get your object into an inconsistent state state that is exploitable . Say an IsAdministrator property . A good example of critical runtime state is the Control.Handle property it can never have the same value when you deserialize . These are practical constraints that the BinaryFormatter class can not figure out by itself . It needs help an explicit okay that it is safe to do this . This cannot be a formal okay when you write the code to de serialize the object that would be easy but it in practice you don t know enough about the class since you did not write it . The class author needs to do this he does so by giving it the Serializable attribute .", "Question : null .. .

Comment : possible duplicate of DataContractSerializer doesn t call my constructor http : stackoverflow.com questions 1076730 datacontractserializer-doesnt-call-my-constructor Comment : Note : The other question I linked to is about DataContractSerializer but the explanation is the same for BinaryFormatter Comment : @Thomas : Thanks that answers it . FormatterServices.GetUninitializedObject is bizarre . .. . Answer : The thing is BinaryFormatter isn t really making your particular object . It s putting an object graph back into memory . The object graph is basically the representation of your object in memory this was created when the object is serialized . Then the deserialize call basically just sticks that graph back in memory as an object at an open pointer and then it gets casted to what it actually is by the code . If it s casted wrong then an exception is thrown . As to your particular example you are only really constructing one car you are just making an exact duplicate of that car . When you serialize it off into the stream you store an exact binary copy of it . When you deserialize it you don t have to construct anything . It just sticks the graph in memory at some pointer value as an object and lets you do whatever you want with it . Your comparison of car1 car2 is true because of that different pointer location since Car is a reference-type . Why Frankly it s easy to just go pull the binary representation rather than having to go and pull each property and all that . I m not sure whether anything else in .NET uses this same procedure the most likely candidates would be anything else that uses an object s binary in some format during serialization .", "Question : I have a data object that is deep-cloned using a binary-serialization . This data object supports property changed events for example PriceChanged . Let s say I attached a handler to PriceChanged . When the code attempts to serialize PriceChanged it throws an exception that the handler isn t marked as serializable . My alternatives : .. . .. . I can t easily remove all handlers from the event before serialization .. . I don t want to mark the handler as serializable because I d have to recursively mark all the handlers dependencies as well . I don t want to mark PriceChanged as NonSerialized - there are tens of events like this that could potentially have handlers . EDIT : Another reason why I can t do this is because the data classes and hence the events are generated and I don t have direct control over the generation code . Ideally the generation code would just mark all events as NonSerialized . Ideally I d like .NET to just stop going down the object graph at that point and make that a leaf . So why doesn t .NET allow an entire class to be marked as NonSerialized .. . .. . -- .. . .. . I finally worked around this problem by making the handler implement ISerializable and doing nothing in the serialize constructor GetDataObject method . But the handler still is serialized just with all its dependencies set to null - so I had to account for that as well . Is there a better way to prevent serialization of an entire class That is one that doesn t require accounting for the null dependencies .. . Answer : While I tend to disagree with the approach I would simply mark the events as NonSerialized regardless of how many there are you could probably do this using serialization surrogates . The idea is that you create an object that implements ISerializationSurrogate and basically does what you re already doing - nothing in the GetObjectData and SetObjectData methods . The difference is that you would be customizing the serialization of the delegate not the class containing it . Something like : .. . .. . Then you register this with the formatter using the procedures outlined in this MSDN column http : msdn.microsoft.com en-us magazine cc188950.aspx . Then whenever the formatter encounters a delegate it uses the surrogate instead of serializating the delegate directly . Comment : Thank you for introducing me to the idea of serialization surrogates . I like it - at least I don t have to pollute the original data class . One thing though - I haven t tried it yet but I suspect that I ll still have the null dependencies problem Comment : I wouldn t think so .

Answer : From Stuart Ellis s An Introduction to ERB Templating http : www.stuartellis.eu articles erb : .. . .. . ERB Embedded RuBy is a feature of Ruby that enables you to conveniently generate any kind of text in any quantity from templates . The templates themselves combine plain text with Ruby code for variable substitution and flow-control which makes them easy to write and maintain . .. . Although ERB is most commonly seen generating Web pages it is also used to produce XML documents RSS feeds source code and other forms of structured-text file . It can be extremely valuable when you need to create files which include many repetitions of a standard pattern such as unit test suites . .. . The main component of ERB is a library which you can call within your Ruby applications and Rake tasks . This library accepts any string as a template and imposes no limitations on the source of the template . You may define a template entirely within your code or store it in an external location and load it as required . This means that you can keep templates in files SQL databases or any other kind of storage that you want to use . .. . Ruby distributions also include a command-line utility that enables you to process templates that are held in files without writing any additional code . Logically this utility is called erb . .. . ERB is part of the Ruby standard-library . You do not need to install any other software to use it . .. . .. . The original article contains more detail and a short guide to using ERB . You can also read the official docs http : ruby-doc.org stdlib-2.2.3 libdoc erb rdoc ERB.html . .. . .. .

Using convention over configuration the output files get created in a file hierarchy that mirrors the input files . Many of the files have the same names and I was able to use the directories to differentiate them . That plan worked until I needed to associate additional info with each file . So I created a YAML file in each directory with the metadata . Now I have both convention and configuration . Yuck . Then I learned Webby http : webby.rubyforge.org and the way it includes a YAML metadata section at the top of each template file . They look like this : .. . .. . If I could implement a header like that I could ditch my hierarchy and the separate YAML files . The Webby implementation is very generic implementing a new MetaFile class that separates the header from the real text but it seems more complicated than I need .

Is there a way to access the erb comments Or maybe a different approach A lot of my templates do a bunch of erb stuff but I could run erb in a separate step if it makes the rest easier . .. . Answer : How about if you dump your content as YAML too . Presumably the metadata is simply a Hash dumped to YAML . You could just append the content as string in a second YAML document in the same file : - .. . .. . Dumping is as simple as : - .. . .. . Loading is as simple as : - .. . .. . Note that the pipe character appears in the YAML so that newlines in the content string are preserved http : www.yaml.org YAML for ruby.html single ending newline .

Answer : They are both templating engines and they have different functionality . There will never be any kind of converter because there are so few cases one should need such tool . Such tool would need to support both language functions but they are not fully compatible there are stuff that exists in one and is not available in another and visa-versa . To answer your original question how you can convert slim to erb my answer is that you need to learn both languages and do it manually . My suggestion is that you learn the one you are planning to use and stick with it My suggestion would be ERB . If you are newbie don t jump on different engines stick with one learn it to the bone and then after years of experience try doing the same or doing better with other engines .

Thanks : Comment : @Mr.Happy Where is it adding timestamp My requirement is to rename file before upload and also show new renamed file name in preview .", "Question : I have a page which allows users to post an advert on my website . This page allows them to upload multiple photos of the product in question . I currently have two forms . The first handles details of the product while the second is a dropzone using dropzone.js allowing them to upload photos . I am keen to keep these forms split as the photos could potentially be very large and I would prefer them to upload instantly rather than waiting for the user to press submit . This should save time overall . Therefore when the photos are put into dropzone they are uploaded to a tmp directory in case the user does not post the entire advert . Once the user submits the first form I am using move uploaded file to move the file to its permanent location . This is the code I am using : .. . .. . However move uploaded file is not working . After consulting the documentation I can see that move uploaded file checks to see whether the file was uploaded using HTTP POST which it was . To be sure I ran a quick test to see whether is uploaded file returned TRUE on my uploaded file but it didn t . How does is uploaded file determine whether a file was uploaded or not I was wondering whether by the time I come to move the file php has forgotten it has been uploaded Is there any other reason my file would not pass this Many thanks Comment : What is form-data Where does it come from FILES Comment : @jakenoble : See the comment - form-data is an array of POST data and contains the file path of the image in the tmp dir Comment : As an extra.. . form-data contains all the data from the first form as described in the question . This form contains the file paths which were put there in hidden fields by dropzone.js . .. . Answer : I think Ive got to the bottom of this.. . .. . .. . move uploaded file only seems to work in the function that the POST data is sent to . In my case I had two separate POST requests sent . The first from dropzone.js which stored the image in a tmp directory . If I had run the is uploaded file in the function that received that POST request it returned TRUE . However once uploaded to a tmp directory I then inserted paths in hidden fields in the second form . I was trying to run move uploaded file which in turn uses is uploaded file in the function which receives the POST data from the second form . However as the file was not part of this POST data just the path to the tmp dir is uploaded file then returned false . I hope that helps someone.. . Comment : I m encountering the same problem with Dropzone.js . How did you solve it", "Question : null .. . Answer : I ve made a dropzone.js that allows visitors to my Wordpress hosted site to upload a large image which displays a thumbnail on successful upload . I followed this handy guide by @soderlind to begin with https : soderlind.no dropzonejs-wordpress-rest-api .. . .. .

CyrilWalrus", "Question : I have a dropzone.js instance on a web page with the following options : .. . .. . It is programmatically instantiated as it is part of a larger form . I have it rigged up to process the queue when the form is submitted . The goal is for my users to be able to use the dropzone to manage images for an item so when I load my edit update view for an item I d like to preload the dropzone with the images that had previously been uploaded for that item . Is there a good way to implement this so that the already-there items don t get re-uploaded when they submit their changes to the image list .. . Answer : Dropzone is so strong and awesome that you can do anything on it . Steps to Follow -- .. . .. . 1 First of all you will have to create a server-side script which will get all the filenames and its size and send it as json response . PHP code : .. . .. . 2 Now you can use the response to display the uploaded files.Write the below code inside the dropzone init function .. . Javascript Code : .. . .. . Note : don t take the whole file url path in filename just take the filename itself thats it . This works Comment : Thanks that works . It should be noted though that calling the addedfile and thumbnail functions directly like that bypasses the corresponding events which is fine for my purposes . Another quirk : I had to generate thumbnails on the server-side to use in the thumbnail call as using the image directly bypasses dropzone s client-side thumbnail generation and just sticks the full-size image into the preview element without cropping so rectangular images would be squashed . Comment : when I preload a image using this method there still is a progress-bar in the image using default css . How do I remove this bar Comment : Also it doesnt follow maxFiles when adding files like this . I have max file as 1 and when I try to upload new one it accepts the file .

OR is there any way so that i can use PHP functions like file-get-contents in .js file and in JavaScript function .. . Answer : The file parameter is an object - Just use console.log to check what data the object returns . If you are uploading your file through PHP and want to return the URL of the uploaded file to display in the text area try this instead - .. . .. . Where file is the object and data is the server response You could return the URL of the uploaded file in PHP after passing the data to it as you would a regular form .

Comment : I ve edited my answer for you - Sorry I misunderstood the initial question Hopefully it works if not let me know . Comment : thank you so much . it worked Comment : but its not working when i am using ace-editor in the textarea .

For reference here is the GitHub issue https : github.com snarfed bridgy issues 350 where we have been tracking this problem . Comment : Correct is that with API v2 there is no username field any more and your app will not be allowed to use the global user id to request user details any more either only the app-scoped user id . What I am wondering here is why is there a need to request post details based on a post URL in the first place Normally your app should work with data that it requested via API before already so external URLs like this would not come into play in the first place . Comment : The goal is for someone to post a reply to or like of a FB status on their own personal website and then use an app to publish it to Facebook . More details here : brid.gy about publishing https : www.brid.gy about publishing . Comment : try my answer maybe it will put you in right direction .. . Answer : Basically you would need read stream for this which your app will not get granted . And yes even though the post is public you still need read stream to be able to get read access to all kinds of posts . You can easily play around with this in Graph API Explorer . First give your app read stream permission to get ids of items in your feed that will give you ids of the form app-scoped user id underscore post id . Then remove read stream by clicking Get Access Token again and using the Clear button and try several of the user-permissions and you will see that for most of your posts even the public ones you will still only get Unsupported get request which just means you are not allowed to read that object . F.e . I have a public post where shared a video post from another page on my timeline the type is video and status type is shared story but neither user status nor user videos allow me to read this post only when I grant read stream again my app can read that post . Same with another public post of type status and status type mobile status update readable with read stream not with any of the user-permissions . In short : What you want to achieve is not possible any more with API v2 and the restriction that read stream will only be granted to apps on platforms where no official FB client exists . Comment : Thanks for the response I m going to go ahead and send you the bounty because it s expiring otherwise . So I actually think our app was grandfathered in on read stream it seems to have it at least for now . Do you know if that should that let me see all posts or just my friends posts or just my own Comment : According to developers.facebook.com docs graph-api reference v2.2 user feed https : developers.facebook.com docs graph-api reference v2.2 user feed only posts by people that have granted your app read stream will be visible to your app when requesting a user s feed which would be the user s own posts and posts made by others on the user s timeline . And after April 30 2015 your app will not be able any more to ask people for any permission besides the ones for user-profile friends and email without your app undergoing review by FB first and read stream will not be granted to any app on a platform for which an official FB client exists .

The SAXParserFactory defines a factory API that enables applications to configure and obtain a SAX based parser to parse XML documents .

Answer : Jing http : code.google.com p jing-trang supports pre-ISO Schematron validation note that Jing s implementation is based also on XSLT . There are also XSLT implementations that can be very easily invoked from Java . You need to decide what version of Schematron you are interested in and then get the corresponding stylesheet - all of them should be available from schematron.com . The process is very simple simple involving basically 2 steps : .. . .. . apply the skeleton XSLT on your Schematron schema to get a new XSLT stylesheet that represents your Schematron schema in XSLT .. . apply the obtained XSLT on your instance document or documents to validate them .. . .. .

Comment : Useful thank you", "Question : From what I understand SAXON is the only library which supports XPath 3.0 in Java . Its JAXP implementation only supports XPath 2.0 . Its XPath 3.0 implementation should be called this way http : www.saxonica.com documentation index.html xpath-api s9api-xpath and requires me to build the document in the first place with its own API rather than using a JAXP-compliant API like DOM4J . This is a pain because I d been careful to abstract away everything that uses XPath to a proxy interface taking a JAXP node and xpath string as parameters but this seems pointless if I have to refactor everything to use SAXON nodes from the top down . Am I misunderstanding something Is there a less painful way Comment : There are various XQuery 3.0 implementations in Java and XPath 3.0 is a subset of XQuery 3.0 . As for JAXP I don t know whether BaseX or eXist expose that API . As for Saxon why do you think that XPath 2.0 is possible with Saxon and JAXP but XPath 3.0 not I think both versions can end up with results that JAXP can t handle but in general I don t see a restriction to XPath 2.0 . JAXP is pretty much geared towards XPath 1.0 that is all that makes having sequences of atomic-values of a rich type system and of nodes difficult with an API that wants to return a node set or a single primitive val Comment : saxonica.com html documentation9.6 conformance jaxp.html http : www.saxonica.com html documentation9.6 conformance jaxp.html Comment : I have tried Saxon 9.7 HE and JAXP XPath with some sample expressions using XPath 3.0 and 3.1 features like or let or json-to-xml and they work fine . Some features like higher-order-functions or inline-functions are not supported in HE but work in EE . .. . Answer : I m increasingly trying to encourage users to use the s9api API in preference to JAXP for XPath processing . There are a variety of reasons : the JAXP interface only gives very half-hearted support to tree models other than DOM it really struggles with the extended type system of XPath 2.0 and now 3.0 and in the case of Saxon it doesn t interoperate at all well with other XML technologies and APIs . However Saxon continues to support the JAXP XPath API with all its limitations both against its own tree model and against third-party tree models such as DOM4J . One thing that we have dropped is support for the XPath services interface whereby an application using the XPathFactory.newInstance method will pick up Saxon if it s on the classpath . The reason for that is that you really need to know when you re writing an application whether you want an XPath 1.0 or 2.0 processor and the JAXP mechanism gives you no way of saying which you want or discovering which you have been given . The result was that a lot of applications were experiencing hard-to-diagnose failures when deployed with an incorrect classpath . If you want Saxon as your JAXP XPath provider you now have to ask for it explicitly . It would be useful if you could be more specific about what you are trying to do and how it is failing .", "Question : Both of them seem to have the same purpose create a XMLReader .

Because noticing after doing all of the implementation seems to be too late . .. . Answer : Although you haven t said so explicitly your question seems to relate exclusively to the Java world and this answer reflects that . JAXP is a set of interfaces covering XML parsing XSLT transformation and XML schema validation . If we just focus on the XML parsing side its main contribution is to provide a mechanism for locating an XML parser implementation so your source code isn t locked into a particular product . Frankly that s of limited value these days the only two SAX DOM parsers in common use are the one embedded in the JDK and Apache Xerces . Apache Xerces is better in every respect except that you need to download it separately . As for the other parsing interfaces they break down into two categories : event-based APIs and tree-based APIs . Tree-based APIs are much easier to work with but can use a lot of memory when handling large documents . The two dominant event-based APIs are SAX push and StAX pull . Pull parsing is something many programmers find easier because you can use the program stack to maintain state information unfortunately though the StAX API is a bit buggy - different implementations have fixed its gaps in different ways . The most complete and reliable implementation of StAX is the Woodstox parser the most complete and reliable implementation of SAX is Apache Xerces . But don t attempt to use an event-based parsing approach unless your application really needs that level of performance and unless you have the level of experience needed to avoid losing all the performance gains at the application level . For tree-based APIs the DOM remains dominant solely because it was defined by W3C and is implemented in the JDK and is therefore perceived as standard also it s the one mentioned in all the books on the subject . However of all the tree models it is unquestionably the worst designed mainly because it predates the introduction of namespaces . Alternatives include JDOM2 DOM4J XOM and AXIOM . I tend to recommend JDOM2 or XOM . Comment : You re right I have changed my title in order to have Java in it . So JAXP is some sort of box that contains DOM SAX XML Parsing XSLT .. . And if I use DOM SAX directly I am indirectly using JAXP as DOM and SAX originate from JAXP I ve read some reviews about XOM and it seems to be quite good but the licence LGPL might make it hard for me to use in my projects . But I have to read more about that . Comment : Note that the SAX DOM implementation in the JDK is based on Apache Xerces and it is actually better maintained than the original . Comment : @AndreasVeithen Yes it is a fork of the original . But it has some very serious bugs which have been known for donkey s years well at least since 2009 and have never been fixed . You don t even get any kind of acknowledgement when you report them they just go into a black hole . Comment : @hamena314 I wouldn t describe JAXP specifically the XML parsing part of JAXP as containing DOM SAX services more as a kind of router that enables you to find a supplier of DOM SAX services . The distinction is that if you know the class name of the DOM SAX implementation you want to use and you don t want portability across different implementations then you can usually bypass the JAXP search mechanism . Comment : @AndreasVeithen for an example of such a bug see bugs.java.com bugdatabase view bug.do bug id 8145969 http : bugs.java.com bugdatabase view bug.do bug id 8145969 .

Because noticing after doing all of the implementation seems to be too late . .. . Answer : JAXP is just Sun s now Oracle s name for a collection of SAX and DOM classes they bundle with the JDK . If you re using JAXP you re also using SAX and or DOM . It s not a different thing . JAXP also adds a few helper classes in the javax.xml.parsers package that fill gaps in SAX 1 and DOM 1 i.e . old versions of these libraries from 15+ years ago . However these are not necessary with SAX2 DOM3 that are used today . Worse yet javax.xml.parsers classes such as DocumentBuilderFactory and SAXParserFactory are designed in a confusing way they re not namespace aware by default so they are almost always used incorrectly . Then developers come here to ask why their program doesn t do what they think it should . Just ignore these classes and use XMLReaderFactory SAX 2 or DOMImplementationLS DOM 3 instead . Comment : Namespace aware means that in an XML document a company might have an XML-element named adress and later in the document a employee might have an XML-element named also adress Is that what you are refering to And despite using differeng Factory classes like DOMImplementationLS instead of DocumentBuilderFactory are there any other differences in usage Comment : @ElliotteRustyHarold I have always taken the view that JAXP is an interface but when you say that Oracle Sun use the name to refer to a collection of SAX and DOM classes that is a specific implementation I think you are right . They have a very bad track record at confusing the interface with their specific implementation . Comment : @hamena314 Besides the builder and factory classes there are NO differences in usage between JAXP SAX and regular SAX . They are the same classes . They are just bundled with the JDK . Same answer for DOM . Namespace aware in this context has to do with how the parser passes local and qualified names to which methods .

Next I replaced Jing with MSV which is here https : msv.dev.java.net now no matter how many links out there lead you to the WebServices stack page at Sun so much for good URLs never change and really my simplistic tests pass . .. . So you may have to jump through some hoops to get RELAX NG support into your JAXP setup - in my case Java5 MSV and Kawaguchi s bridge worked but the comments indicate it should be doable with Java6 as well - but once you manage to configure everything correctly XMLUnit will now be there to let you assert your document s validity in Unit tests .

Work with an object representation of SVRL :", "Question : As far as I can tell JAXP by default supports W3C XML Schema and RelaxNG from Java 6 http : java.sun.com javase 6 docs api javax xml-validation SchemaFactory.html . I can see a few APIs mostly experimental or incomplete on the schematron.com links page http : www.schematron.com links.html . Is there an approach on validating schematron in Java that s complete efficient and can be used with the JAXP API Comment : Either JAXP doesn t support RelaxNG very well or I must be doing something wrong when I try to use it . Comment : Haven t tried RelaxNG tbh just WXS Comment : Not quite a dupe but see also Where can I find a Java implementation of an ISO Schematron validator http : stackoverflow.com questions 10126256 where-can-i-find-a-java-implementation-of-an-iso-schematron-validator .. . Answer : A pure Java Schematron implementation is located at https : github.com phax ph-schematron It brings support for both the XSLT approach and the pure Java approach ." ] }

Answer : Actually they have almost nothing in common . A Linux chroot environment is just what resolves to for a single process . Anything the process can do with access to that tree it can do . So in general it can e.g . enumerate other processes on the system and if it is a root process it can still take over the machine . A FreeBSD jail on the other hand is more like a virtual-machine than a Linux chroot jail . It is a partition of the system with its own file system user accounts etc .

Answer : The sysctl security.jail.sysvipc allowed has to be set on the host not in the jail . But if you set jail sysvipc allow YES in the host s rc.conf that should set it for you see etc rc.d jail . You should check on the host if the value of security.jail.sysvipc allowed changes to 1 if you start the jail . If not there is probably something wrong in your rc.conf .

I read about jail the solution sound great for Server Systems . So my idea for my webserver was to create 3 jails . One jail for mysql one for nginx and one for php-fpm .

Which solution do you use Or do you have better solutions .. . Answer : I would not separate php-fpm but it s possible . The overhead for IP communication is not that big these days and not that important considering the processing that the database and php processor need to make is far bigger . Especially since there is no actual wire involved . The packets are routed through the interface via a loopback construct and don t hit the wire . The advantage of separation is that you can move the jail to another physical machine if need be and moving jails is a breeze . To clarify why not to move php-fpm in a separate jail is that modifying the website becomes a two-task process for static content images and dynamic-content php files . The advantage is that a breach in the webserver software is not able to modify php code .

Answer : I really don t know if it s the best solution but if you can use Unix domain sockets you can share a mount between the three jails . The namespace is isolated they can t create a socket outside the shared mount point and they should be able to communicate . To create the shared mount you can use a nullfs mount . A nice rather advanced guide about jails http : www.freebsd.org doc en US.ISO8859-1 books handbook jails-application.html also speaks about nullfs mounts . Of course this mount point should be used only for the sockets the other files should stay separate .

Answer : I need to invoke scripts.py of home ubuntu in the jail with restricted jail user .. . .. . You said that scripts.py is located in home ubuntu online judge which is NOT in the Jail . So either you have the jail user restricted to Jail or not . If the restricted jail user should execute online judge scripts.py you d have to make it accessible somewhere under Jail . The Jail user should never be able to access any of the home ubuntu files except input output input txt which i can give then execute permission .. . .. .

Is this doable How Comment : this could be useful for you . docs.openstack.org infra jenkins-job-builder http : docs.openstack.org infra jenkins-job-builder definition.html variable-references . passing a variable reference for that instance cane be helpful .. . Answer : In the job template you want to add a disabled property which takes its value from a parameter . Parameters default-value can be set at the defaults and project level . So in theory you could pass the disabled value at the job level : .. . .. . Note obj : prefix is to pass the boolean as is .

In doing so I am trying to figure out the right best way to include a job-template from an external file using the include custom tag .

So far I have gotten this to work : .. . .. . job-template.yml .. . .. . job-1.yml .. . .. . .. . .. .

Is there way to get the entire template definition into the template file This will become particularly annoying if ever we need to pull in multiple templates from multiple-files . .. . Answer : Jenkins-jobs takes a path argument which can be a directory holding your files job-template.yaml job-1.yaml and job-2.yaml . It will assemble them as a single YAML document so you do not need to use include . So you can write : .. . .. . job-template.yaml .. . .. . job1.yaml .. . .. . job2.yaml .. . .. .

Answer : It s hard to tell from your question exactly what you re looking for here but assuming you re looking for the basic structure : .. . .. . Python has good support on most platforms for XML Parsing . Chances are you ll want to use something simple and easy to use like minidom . See the XML Processing Modules in the python docs for your version of python . Once you ve opened the file looking for project and then parsing down from there and using a simple mapping should work pretty well given the simplicity of the yaml format . This snippet will print just a few lines of the eventual configuration file but it puts you in the right direction for a simple translator . Based on what I ve seen there s not much room for an automatic translation scheme due to naming differences . You could streamline the code as you iterate for more options and to be table driven but that s just a matter of programming this will at least get you started with the DOM parsers in python . Comment : this is very useful suggestion almost fits for my need just try to reuse the xml2json github.com hay xml2json https : github.com hay xml2json code to load into json and manipulate the json internal format then dump into yaml . Comment : I m not sure what you would get from xml2json that isn t in this example . Since the yaml and XML formats do not use the same keywords in many cases you can t just walk the tree and do a format conversion hence my suggestion for how you could implement such a conversion with minimal repetition .

Answer : I suggest querying and accessing the xml questions tagged xml with xpath questions tagged xpath expressions using xmlstarlet questions tagged xmlstarlet on the command-line and in shell scripts . No trouble with low-level programmatical access to XML . XMLStarlet is an XPath swiss-army knife on the command-line . xmlstarlet el shows you the element structure of the entire XML as XPath expressions . xmlstarlet sel -t -c XPath-expression will extract exactly what you want . Maybe you want to spend an hour or two on freshing up your XPath know-how in advance .

But I d like to learn if this software can be also ported to different operating systems especially to Slackware . I am the author of Slax a Slackware-based operating-system so I know lots of the internals of a working OS library dependencies and so on . From my point of view installing a debian package to Slackware or other distribution is fairly possible if both the distros share similar libraries which most Linuxes do nowadays . Slackware despite it s focus on stability is usually using recent libraries as like Debian . As far as I understand apt it s just an application which tracks dependencies and has a list of mirrors from which to download packages . Unpacking the deb packages is a matter of .. . .. . Most init scripts will be the same if the Sys-V init style is supported . Some of the Debian packages may not work out of the box especially those which are deeply system-related like udev for example but majority of the APPLICATIONS should install and work OK on Slackware in my opinion . I tried Google s official Chrome Browser package for Debian and it works just fine on Slackware . Are there any drawbacks in porting apt-get to Slackware or other Linux Did anybody attempt to port it already Thank you .. . Answer : The package slapt-get is the Slackware implementations of apt-get . slapt-get install whatever-package .. . .. . Any way you should be able to compile it on any OS . Of course you might have to do some small changes to the source if the repos structure and files to download are very different . Comment : slapt-get won t install Debian packages in Slackware . It only serves for the purpose of installing official Slackware packages this won t help me . I wish to use the huge Debian repository of packages not just the official Slackware ones . Comment : Sorry I did not understand . Since both distros got apart things should have changed a lot internally . So you have high or very high chances that your packages dependencies installations are going to break other things . Is the same with Ubuntu and debian . You could compile apt and use it but as a matter of fact is not advisable to do it . Maybe you could also try to configure slapt-get to go to a Debian . I have done something like that with Ubuntu and I have managed to break a few systems like that in the past but in this last one I am just speculating . Any way is not advisable .", "Question : I tried to install MySQL workbench in Debian Operating System by using workbench for linux distribution but its not working . Comment : What is your error message What is not working What have you tried Please provide more information .. . Answer : A common method is to use the operating-system s package system . For Debian MySQL recommends installing the official APT repository http : dev.mysql.com downloads repo apt and then use apt-get as you would normally . The official repositories contain most MySQL products and typically they are newer versions than the versions provided by vendors such as Debian Ubuntu Fedora CentOS Ubuntu and so on . So for Debian download the appropriate APT file and then execute something like the following The mysql-apt-config 0.3.5-1debian8 all.deb file name that you download might be different so adjust that accordingly : .. . .. . cd Downloads sudo dpkg -i mysql-apt-config 0.3.5-1debian8 all.deb sudo apt-get update sudo apt-get install mysql-workbench-community .. . .. . You might notice that both mysql-workbench and mysql-workbench-community packages will be available via apt-get but mysql-workbench-community is the package you want . Use apt-cache show insert package name here on both packages to see the difference . Installing the package file mysql-apt-config 0.3.5-1debian8 all.deb above is a one time deal so feel free to skip this step when updating Workbench or installing other MySQL products .", "Question : null .. . Answer : Note : this Q is from curiosity not any practical need or intention . Debian is used as an example but the Q applies to Red Hat or any distro or OS with a packaging system that maps out package conflicts . .. . .. . In 2016 Debian has tens of thousands of packages . dglob from the debian-goodies package is handy for getting a quick count : .. . .. . Some packages conflict so it s impossible to install all available packages at once . So what s the maximum possible number of installable packages for a given system Presumably a brute-force trial and error method would be far too time consuming i.e . make a gazillion lists of every possible combination of package names and run apt-get install on each list then sort for the longest conflict free list but maybe there s a more abstract yet feasible method . Various related questions follow from that such as.. . given a package foo how to find the maximum number of installable packages that don t conflict with foo For all possible foo packages which has the smallest such maximum making it the most quarrelsome package Answers for Red Hat etc . or even other OSes would be fine too . Comment : Questions about general software are off-topic since every package isn t focused on tools for software development . Your question might be a better fit for the Unix and Linux http : unix.stackexchange.com stackexchange site . However how many mp3 players do you really need to install Comment : Oddly enough for this question the contents of the packages are wholly irrelevant . Since it makes no difference then if you like let us suppose a Debian distro exists consisting exclusively of that subset of Debian packages specifically intended for software development . The question of how to feasibly find a maximum number of installable packages would be unchanged . Also see the first line of the OP which begins with Note : .. . where your question about mp3 players was anticipated and in part answered . Comment : The question of how to feasibly find a maximum number of installable packages would be unchanged And still entirely general use . Comment : Think of it as more of a graph-theory and logical problem which maps to a given package dataset and whether or not the problem can be solved with the programming tools at hand . It s not a strictly Debian puzzle it could be asked of Red Hat .rpm files or any distro s packaging system or on any OS with a conflicting package tree and any platform whatsoever . Solve one in the abstract solve them all . Perhaps this question needs clarifying with regards to that.. .", "Question : I m new to Linux Debian world . Irssi requires GLib so I installed 2.6.6 version . When trying . configure Irssi it gives : .. . .. . Can someone enlighten what s the deal Comment : Did you install glib version 2.6.6 from a source tarball .. . Answer : Packages for libraries are split into at least two packages--one for the shared library itself which is what you need in order to run software which uses the library and another for the extra stuff necessary to compile software which depends on that library . In Debian the names for those packages are libglib-2.0 and libglib-2.0-dev . You had version 2.32.2 of libglib-2.0 installed but in order to compile software like irssi you need libglib-2.0-dev .

Unfortunately installing an ancient version of glib like you did 2.6.6 was released on 2005-08-01 may have broken your system pretty badly since it is likely other software depends on a much newer version of glib . If you didn t pass any arguments to . configure it probably installed into usr local which would be good because it may not have overwritten anything you needed in usr which is where the packaged version gets installed . So you may be able to just go into the directory you compiled 2.6.6 in and run : .. . .. . You ll probably also want reinstall the package from Debian too : .. . .. . I don t know what you re trying to do with irssi but instead of installing it from the tarball you may want to just use the Debian package : .. . .. . Unless you re actually modifying the code you almost never want to install from tarballs or git for that matter . I suggest you find whatever graphical package manager you have installed--what that package is depends on the version of Debian as well as which desktop environment you chose but likely choices are GNOME Software Center or Synaptic .

The debian control file comprises these lines : .. . .. . The dependencies are thus automatically set in the created package . However the version required of libstdc++ is too strict . The package requires libstdc++6 4.9 and I want it to be set as libstdc++6 4.8 . For this purpose and at the reading of this page http : manpages.ubuntu.com manpages hardy man1 dh makeshlibs.1.html and this page http : manpages.ubuntu.com manpages precise man1 dh.1.html I edited the debian rules file which now looks like : .. . .. . The last two lines however did not make the job . Has anyone already did this kind of customization on a Debian package Thanks Comment : I ve read the documentation and your proposed solution seems valid . When you inspect the resulting DEBIAN control file does it contain any particular version You said you re building the packge for the latest Debian stable I assume jessie which packages libstdc++6 4.9.2 . Is it necessary under these conditions to relax the version requirement In other words wouldn t package targeted for different distribution work better Comment : The resulting DEBIAN control is what I check after the package is done . I have Jessie which packages lidstdc++4.9.2 as you said . I don t know if it s a good idea but other people said that the software can be built with the version 4.8 so I could relax the version in the package . The package would be thus compatible with other debian-based distributions . .. . Answer : In general debhelper does a very good job at detecting dependencies . If it says that your packages requires libstdc++6 4.9 than your package most likely does require this specific version and will fail with e.g . libstdc++6-4.8 . If you don t believe me try it out force-install your package on a system that has only libstdc++6-4.8 installed and see whether everything works .. . .. . If some people claim that it can be build with libstd++6-4.8 or rather gcc-4.8 then I see to possibilities : .. . .. . either those people are mistaken .. . OR the binary in your package will be slightly different depending on whether it was built against libstdc++6-4.8 or 4.9 .. . .. . Most likely the second point is the case . This can have numerous reasons e.g . : - your package automatically enables features if it detects libstdc++6-4.9 - some implementation detail in libstdc++6 has changed which makes the resulting binaries incompatible or at least : not backwards compatible .. . .. . If you want a package that can be used with libstdc++6 4.8 than you should use libstdc++6-4.8 or most likely : the entire g++4.8 toolchain for building the package .", "Question : For eg : is there an alpine package corresponding to apt-transport-https or software-properties-common .. . Answer : apt-transport-https as the name suggests is some extension to apt Debian s package tool .

Why do you think that you need these packages on Alpine Comment : I have an ansible script that installs these dependencies or packages on ubuntu to setup an environment and I need to write tasks which will setup the same environment on alpine os Comment : Alpine is not Ubuntu nor Debian it s very different linux distribution .

Comment : This is totally unrelated to Debian . If you want to use YouCompleteMe a Vim plugin unrelated to any operating-system you need to compile it to get it to work . This is not a bug and will not change . The reason you need to compile it is that in order to be very fast the plugin uses C C++ code which only runs when compiled . This is different from many other Vim plugins written in pure Vimscript or Python which don t need to be compileD .

The repository you probably talk about is the Debian package management system . It includes lots of things you can install via apt-get install programname . The packages in this repository don t need to be compiled they work out of the box for you . YouCompleteMe is NOT a Debian package . It is a piece of software unrelated to Debian which you will find ONLY on Github . Github is a place where people have their source code which sometimes needs to be compiled sometimes works out of the box . You cannot install YCM via apt-get install . Comment : @cbaumhardt no .

Not sure where to get this thing and fix this problem . Please advise . .. . Answer : Debian uses apt to install packages . apt-get or aptitude are front-ends to the apt systems . whenever you ask the system to install a given package it will first need the actual package files . now apt can fetch the requested packages from a number of different places including read-only media like CDROMs or DVDs or the internet via http or ftp . these places can be configured in the etc apt sources.list file . if you have installed Debian from the set of CDROMs then your sources.list will tell apt that it can get package files from the cdrom-drive . obviously you need to have the correct CDROM inserted in your drive . on a virtual-machine you will find that you can use ISO-images of the files and tell your virtualization software vmware to make a given ISO available to the client . however the usual way is to add an internet ressource to sources.list so you don t need to juggle with CDROM images and you will always get any bugfixes . obviously your machine will need to be online for this to work . add an official online debian repository to your sources . the following uses http : http.debian.net which should automatically use a mirror that is physically close to your machine : .. . .. . then update the cache .. . .. . and install the required package s Comment : Thanks for the answer .

My situation is each row in my data table has a column with 4 radio buttons . I would like to be able to filter that data with Yadcf .

I tried to look through the code a bit and see that yadcf sees the aData for column 5 has empty . I am not sure why . Does anyone have any ideas how I can make this work .

Am I right thinking that the problem is my router blocking the messages How can I check this and also how can I fix this . Best regards .. . .. . Bart .. . Answer : Your router is most probably blocking incoming JMS messages as it does not know to which local client after NAT it belongs . You will have to configure port forwarding in your router . Please refer to its documentation for that . To know which ports to forward you will have to consult openjms s documentation to see how it assigns ports to clients .", "Question : With regards to the problem Bart is having in NAT router blocking JMS messages http : stackoverflow.com questions 13455209 nat-router-blocking-jms-messages I am trying to find the port-number that clients receive openJMS messages on . After searching for ages on the web I can only find information about the server ports nothing on the client . This is for a tcp connection . If anyone can point me in the right direction I would be very grateful . Thanks .. . Answer : In general the client port-number will be different for each new connection . I could find no evidence that OpenJMS clients use specific port numbers when communicating with servers . Here are a few explanations . 1 . Port Numbers http : publib.boulder.ibm.com infocenter cicsts v3r1 index.jsp topic com.ibm.cics.ts31.doc dfhtl topics dfhtl2d.htm .. . .. . When a client process first contacts a server process it may use a well-known port-number to initiate communication . Well-known port numbers are assigned to particular services throughout the Internet by IANA the Internet Assigned Numbers Authority . The well-known port numbers are in the range 0 through 1023 . .. . Well-known ports are used only to establish communication between client and server processes . When this has been done the server allocates an ephemeral port-number for subsequent use . Ephemeral port numbers are unique port numbers which are assigned dynamically when processes start communicating . They are released when communication is complete . 2 . TCP IP Client Ephemeral Ports and Client Server Application Port Use http : www.tcpipguide.com free t TCPIPClientEphemeralPortsandClientServerApplicatio.htm .. . .. . In contrast servers respond to clients they do not initiate contact with them . Thus the client doesn t need to use a reserved port-number . In fact this is really an understatement : a server shouldn t use a well-known or registered port-number to send responses back to clients . The reason is that it is possible for a particular device to have both client and server software of the same protocol running on the same machine . If a server received an HTTP request on port 80 of its machine and sent the reply back to port 80 on the client machine it would be sending the reply to the client machine s HTTP server process if present and not the client process that sent the initial request . .. . To know where to send the reply the server must know the port-number the client is using . This is supplied by the client as the Source Port in the request and then used by the server as the destination port to send the reply . Client processes don t use well-known or registered ports . Instead each client process is assigned a temporary port-number for its use . This is commonly called an ephemeral port-number . 3 .

Connection Properties from DB Visualizer http : i.stack.imgur.com k62sI.png Comment : Yes any JDBC-aware tool should be able to connect to your Derby database using the Derby JDBC driver . Perhaps the reason you didn t see any records is because you looked in the wrong table or the wrong schema . Perhaps the reason you didn t see any records is because your message-queue software deleted those records .

And whatever it sendMessage does the message is always removed from the queue . How can i keep the messagen in queue to be called later Thanks .. . Answer : The message is removed from the broker queue due to the fact that the session you are using is set to auto acknowledge . This will automatically send an acknowledgement to the broker that the listener has received a message for the consumer with which it is associated once the onMessage method has executed to completion . This then results in the message being removed from the queue . If you manually take over the acknowledgement process you can choose to only acknowledge the receipt of the message at a time of your choosing be that 15 minutes later or whatever criteria you have for the consuming client . Setting the Session Session.CLIENT ACKNOWLEDGE will allow you to do this but then you will have to manually send an acknowledge in your consumer code . By calling acknowledge on the message msg.acknowledge inside your onMessage method within your listener . This will then acknowledge the receipt of messages consumed within that session and remove them from the queue .

You could even have a trigger client generate a new trigger message in a new queue if that is absolutely necessary . Comment : @RaGe yes it s seems acceptable . Could you try to explain in an answer maybe with some reference When arrives a message and myApplication is still in execution WMQ doen t launch it again it s supposed that the user application consume all messagges in the queue.Can I expect similar behavior Or all messages call onMessage .. . Answer : qpid does not have a websphere-MQ like monitor trigger feature . I know ActiveMQ doesn t either and I suspect this may be true of other JMS providers as well . However it is possible to roll out your own monitor-trigger . A homebrew monitor-trigger would then become an application process albeit light-lightweight that you will have to manage though would you be better off managing an actual application thread itself .. . .. . To implement a monitor trigger in qpid : .. . .. . JMS spec defines an asynchronous delivery mode . See section 4.5.2 http : docs.oracle.com cd E19957-01 816-5904-10 816-5904-10.pdf . So you should be able to do this with any JMS provider . An asynchronous listener https : docs.oracle.com cd E19798-01 821-1841 bncfh index.html implements the javax.jms.MessageListener interface . The method onMessage needs to be implemented and serves as the callback function when any new message appears on the queue it is subscribed to . Suppose the main application queue is mainQ . You create a new MessageListener for mainQ in browse mode - so as to not actually consume any messages from mainQ .. . .. . In the onMessage function you can either create a new message in a separate triggerQ or you can skip this step and get right to starting up the application .

I think for that both RestKit and AFIncrementalStore are good candidates . However I also need to be able to save data offline and push it to the server when the app is online . I am trying to understand which is a better framework to use for the application . Also from some of the online resources http : sealedabstract.com code nsincrementalstore-the-future-of-web-services-in-ios-mac-os-x it seems that using faulting on AFIncrementalStore could potentially cause the thread handling ManagedContext usually the mainThread to get stuck while furnishing the network request to get a property . Is it a big deal PS : Adding afnetworking tag since afincrementalstore tag is not available .. . Answer : AFIncrementalStore works within Core data sending back to your Web service . It uses the relatively new API Apple provides called NSIncrementalStore . RestKit works from outside Core Data binding HTTP requests to Core Data loosely using the object mapping architecture RK provides . Here are some pros cons for both : .. . .. . New RestKit version 0.2.x is ligther than the 0.1 version .. . RestKit now use the really good AFNetworking for all his HTTP request work just like AFIncrementalStore . ResKit has A LOT of test-coverage .. . AFIS is really light since it s built on NSIncrementalStore .. . AFIS give you a bit more flexibility since you re pretty much on your own .. . RestKit is pretty huge and can be scary at first .. . RestKit is a complete solution but takes time to fully wrap your head around all its concepts .. . .. . My final recommendation would be to take the time and try both . What I can confirm is you ll need to drop a bit more lines-of-code using AFIS since it does not take you by the hand as much as RestKit so it s really a matter of preference . Hope this will help you make the right choice Comment : Thanks for sharing your point of view . I ll start to try with RestKit since the advantage AFIncrementalStore brings to table is property faulting which is not high in my feature priority right now .", "Question : Is it possible use RestKit to POST a request to a server that expects a JSON list of dictionaries : .. . .. .

In my podfile I ve turned on the use frameworks flag to force cocoapods to use dynamic frameworks . Putting import RestKit in my swift file causes a build failure : RKValueTransformers.h file-not-found . RestKit is set up to use a handful of other libraries and include their headers into the project AFNetworking RKValueTransformers TransitionKit etc . According to an article for cocoapod authors http : blog.cocoapods.org Pod-Authors-Guide-to-CocoaPods-Frameworks I believe the issue is that the way to import and include these libraries need to change to work with dynamic frameworks and cocoapods . Either the autogenerated umbrella file needs to import these files for use or RestKit needs to import these libraries using @import RKValueTransformers or import RKValueTransformers RKValueTransformers.h . I am not an expert at Objective C Cocoapods or RestKit so looking to see if anyone has gotten this working and I am doing something wrong or if it requires a change made to RestKit . Comment : Hey did you get succeed Comment : Leaving an answer below .. . Answer : This is a bug currently in RestKit . Sam Giddin https : github.com segiddins has an open PR https : github.com RestKit RestKit pull 2145 right now that fixes the issue .

An then use JSONKit to parse the response data to a NSDictionary . Example : .. . .. . .. . .. . How can I use the benefit of RKObjectMapping from RESTKit as a standalone library to do the object-mapping Thanks in advance . Comment : Be specific about what your problem is and what you ve tried to fix your problem . Comment : I ve updated my question . Thanks . .. . Answer : If you use RestKit it will replace all of your current code . RestKit is built on top of AFNetworking so you would post your object from RestKit and map the resulting data back into that object . Whether this is useful depends on the purpose of your POST . What you have currently can be trimmed a little if you don t use RestKit by using AFJSONRequestOperation . In general the question boils down to : .. . .. . 1 . What is the data you re posting and expect to receive .. . 2 . How complicated is your mapping .. . .. . If the mapping isn t complex RestKit is probably overkill . From your code it looks like you re making a simple post so that should be fine and you would construct your mappings to update the object you re posting even though no data was actually taken from that object to make the request . Comment : I know RESTKit is build on top of AFNetworking . But RESTKit is too heavy for me to use . But I can t find a good-enough object-mapping library than RESTKit . So I m thinking only to use the Object-mapping benefit from RESTKit . And AFJSONRequestOperation does not do the object-mapping jobs . Comment : RestKit only adds mapping on top really if you want to use the mapping then the easiest approach is to directly use RestKit for everything than trying to do the download yourself and then push that data into RestKit which is contrived .", "Question : null .. .

When i use create new file to create NEManagedObject subclass i ve got Elements class . Comment : as a question : how about RestKit Is it really helpful for you .. . Answer : I used RESTKit until the .20 release a few months ago . In all honesty while this library has great intentions in my experience it ends up wasting far more time than it was ever meant to save me . I have used it with API s created with .NET MVC PHP python Django TastyPie and hacked it to do some stuff with Twitter . This all ended up being a very interesting academic exercise but in the end was little more than that . Both the old new versions of RESTKit assume ALOT about the way your API is going to be responding to requests . With the .10 release there was a fair amount of customizability through the use of Obj-C Blocks . I could intercept the request response of an RKRequest and pretty much override anything that RESTKit was going to do . This seemed fairly awesome . Now with the .20 release everything got very.. . clever clever code is usually not good . Instead of trying to remain generic and malleable RK now does all kinds of convenient things for you . This effectively takes away your ability to jam it into whatever non-idealized and realistic shape your API has taken . At this point I have gone back to writing all of my code using AFNetworking https : github.com AFNetworking AFNetworking . I d rather take the extra time to write my own parsing code and know that when my Unit Tests pass I m done . NOT spend hours trying to get RK to log out meaningful error messages . The other real problem with RK was that it does not account for being offline . It was designed with the assumption that your application is ALWAYS online and simply mirrors a persistant store in the sky . My applications all handle content-creation on an iOS device which MAY OR MAY NOT be online at the time of content-creation . This is the main reason I was customizing RK .10 . When I saw the changes in .20 I decided enough was enough and went back to doing things the old way . Maybe I ll just write my own CRUD RESTful framework cause I m starting to get tired of spending time using very specialized libraries that try to do everything with as little responsibility being left to the application developer as possible . Frameworks like this tend to be Swiss Army Knives . They look really awesome on paper THEY CAN DO ANYTHING then you actually try to cut something and the blade is too dull or breaks off . Good software does very few things very well and if it sounds too good to be true it probably is . Comment : I understand you point of view . This would deserve some debate . As an Objective-C beginner coming from python world I admit I haven t yet been able to do anything with RestKit . BUT trying to be the devil s advocate we can skip whatever suggested RK s smart layer we want and it seems to be designed also for offline content with his CoreData integration https : github.com RestKit RestKit wiki Object-mapping core-data isn t it I na vely tend to think that these upvotes are coming more from people discouraged by the complexity than from people understanding the whole stack . Comment : As a python programmer perhaps you are familiar with Django Django is a pretty large framework but it is EASY and very DRY . I love Django so at least for me personally the size of RESTKit has little to do with my issue . I have an issue with the overcomplicated design . I built my first Django App in about an hour with a working ORM . I built my first RESTKit service on a real API in just over 4 hours . And RESTKit is really a toolkit for one kind of problem while Django is a full application framework . I m talking about the simplicity of good design . Comment : And I should really say my first production RESTKit service took about 4 hours to get ANYTHING working . I worked on getting 6 different endpoints working with no mapping issues for over 2 weeks . Thats too much If I were smart I would have just written my own client like I have in all my other software before RK . Comment : I m indeed a Djangoist too my favorite framework by far . I try to avoid comparison between Django and Xcode or Python and Objective-C because I would be discouraged to quickly : I did noticed that I spend about 20x more time to do every little thing in Objective-C than in Python . And I think that RK sadly inherits from this verbosity and heaviness . Maybe RK is not as much customizable as it could but it seems also largely disadvantaged by the supporting language and Apple standards.. . Comment : Indeed please don t let what I ve said steer you away from Objective-C.. . its awesome lol . The verbosity of ObjC is made up for by the fact that when well-written which most is it is incredibly readable . Cocoa in general is an amazing example of strict design guidelines and a well thought out framework . Xcode also makes up for the verbosity with autocompletion .

Just ask them double check and your app will pass . I tried it and success Good luck Comment : Yes i had a slight snag that our web servers werent working on IPV6 . Once i fixed that the app review passed and got accepted Thank you Comment : @user19342 : Your servers don t need to support IPv6 .. . Answer : How do you check if an application will work on an IPV6 only network with a remote-server .. . .. . Your solution seems fine Apple recommends a similar setup https : developer.apple.com library ios documentation NetworkingInternetWeb Conceptual NetworkingOverview UnderstandingandPreparingfortheIPv6Transition UnderstandingandPreparingfortheIPv6Transition.html apple ref doc uid TP40010220-CH213-SW16 . Does RESTKit 0.24.0 support IPV6 networking . RESTKit uses AFNetworking as its underlying network stack so it should not be affected by the transport characteristics of the underlying network . It appears that AFNetworking supports IPv6 although there is some forum chatter about the correctness of the reachability implementation and no official documentation that I could find that explicitly asserts support . Bottom line as long as you are using host name rather than address literals to retrieve your REST resources you should be fine--especially as your testing is working as expected . Comment : Thanks for the response . Our web servers weren t prepped to handle IPV6 once we fixed that the app got accepted .

In theory you should be able to just upload the SQLite but I have no idea what kind of consistency guarantees you will have about the data . 2 .

System . ComObject.Value xcopy ProjectDir MyFolder OutDir .. . Answer : I think editing the PostBuildEvent property is the wrong way to go about adding a post build action to a user s project . I believe the recommended way is to put your custom-action into a target that is then imported into the project file . As of NuGet 2.5 http : docs.nuget.org docs release-notes nuget-2.5 if you include a build folder in your package at the same level as content and tools and it contains a packageid .targets file or packageid .props file NuGet will automatically add an Import to the project file when you install the package . For example you have a package called MyNuGet . You create a file build MyNuGet.targets containing : .. . .. . This creates a custom target that is configured to run after the standard Build target . It will copy some files to the output directory . You do not need to do anything else in install.ps1 . When the user installs your package NuGet will automatically add an Import to the user s proj files and your target will run after the Build target is run . Comment : mike z is exactly right . This would be the Proper way to do it . Comment : @mike-z this is great . I didn t realise you could do this with NuGet it worked first time .

So we can t hardcode the path into the project file . If we could read fro an external file we could then ignore that in source control and just rely on setting the path value in that file . If reading in a file isn t possible is there any other way we could achieve this .. . Answer : As far as I can tell you can t read an external file into a variable in a VS post-build event . However you can run an external batch-file and provide it with arguments . This allows us to do per-developer post-build batch scripts by excluding such scripts from source control then checking for their existence in the post-build event and executing them if they exist like so : .. . .. .

Answer : post-build-event is just a command you can have visual-studio run after it s finished - maybe to kick off tests or build an installer . It s in properties- build events in the menu - right-click on the project . The SBR file is used by visual-studio to browse sources and lookup which function is in which file .

It would be nice to use the same build solution over multiple solutions too possibly enabling disabling certain projects so don t copy unit tests etc . Thanks .. . Kieron .. . Answer : You can set common OutputPath to build all projects in Sln in one temp dir and copy required files to the latest build folder . In copy action you can set a filter to copy all dlls without test in its name . There exists more complicated and more flexible solution .

You can place it here C : Program Files MSBuild v4.0 Custom.After.Microsoft.Common.targets or here C : Program Files MSBuild 4.0 Microsoft.Common.targets ImportAfter PublishToLatest.targets .

Answer : Are you sure you want to do this as part of a compile I would recommend using project references in solutions rather than the GAC if you can avoid it . Copying files is one thing but registering in the GAC is fairly intrusive and you may want to consider the other environments your code is compiled in . Things like other developers machines and test-environments build servers etc .

Answer : RMI doesn t provide any sort of federated or distributed naming service . RMI is structured to allow you to run an RMI registry on your server . It hosts services that can be accessed across the network however the services run locally on that server . The service being provided must be started - and rebind - on the server - not on any client system . Local address only . Your clients should then reach out to that server.. . Comment : I m trying to implement a mobile agent which will run on some rmi servers to do some work on them and return the results to the starting station so RMI servers implements the environment that hosts this agent to do its work and send it to the next station which it ll locate through the registry. . so you say that I can t create a multi-hosts servers each server running on different machines but on the same network . right Comment : I m saying each server in your set of multi-hosts must individually run a local rmiregistry to which a local copy of your service is bound . If you want your client to be able to rotate to different RMI services that s a layer above what RMI provides you ll have to come up with some way to do that outside of RMI JNDI naming may be helpful here : - Comment : but if the agent is running on machine A and want to move to machine B how can it locate B if there is no united registry that contains all the services Comment : That s a great question and one for which RMI doesn t provide an answer . Comment : Your description is close enough to solve this problem but nevertheless inaccurate . The Registry will only accept bind rebind unbind requests from processes running in the local host but there is no requirement that the objects being bound are running in the local host .

EDIT This answer applies to the original version of the question . The answer to the current version is no unless you write something yourself which isn t hard .

Comment : Please check my updated question . I am resposible for rmiregistry service . the one which holds the rmi data in cache . the service goes down the dependent applicition needs to rebind .i.e . restart . Comment : You don t need the RMI Registry after the initial lookup with Activation . Just persist the stub and it will resurrect itself on next usage . Comment : Well that is true from application point of view but if the registry service crashes and restarts any application previously registered will be cleaned up . And app will get object not bound exception on resolve . Comment : @VinayTiwari I can only repeat what I said . You don t need the Registry after the intial lookup . As a matter of fact you don t need it at all in Activation . You just persist the stub resulting from the intial setup and load it every time you start the application from wherever you persisted it .

What I would like to know is the pros and cons of each option and mainly when and why it is recommended to use one instead of the other . .. . Answer : Most people use the Registry . You might use LDAP if you already have an LDAP server but you wouldn t go to the trouble of installing an LDAP server just for RMI .

The above mentioned issue occurs in my Linux Mint VM while if I run the exact same code and configuration on my Windows machine everything goes fine . Comment : I confirm that in Windows I do not need to pass the codebase argument to the rmiregistry while in Linux Mint I need it I recorded everything and setup a repository with the example and instructions to run it github.com mottalrd RMITutorial https : github.com mottalrd RMITutorial Warehouse v1 set of projects Comment : Is it possible that in Linux you have a CLASSPATH environment variable that is set when you start the Registry and points to your server code .. . Answer : It seems that with the first procedure the RMI registry is ignoring the java.rmi.server.codebase property . That s correct . The reason is that as of JDK 7u21 the java.rmi.server.useCodebaseOnly property is true by default whereas in prior releases it was false by default . When useCodebaseOnly is false the RMI Registry and RMI clients use the codebase that has been passed to them from the server . Now that the default-value is true the registry and clients ignore the server s codebase property . The registry and clients must either set their own codebase property to match that of the server or not recommended they could set useCodebaseOnly back to false . See RMI Enhancements in JDK 7 http : docs.oracle.com javase 7 docs technotes guides rmi enhancements-7.html for further details . The RMI Tutorial http : docs.oracle.com javase tutorial rmi hasn t been updated to reflect this change . Sorry about that . I ll make sure it gets updated . Comment : Very very useful answer Thanks a lot you saved me a lot of time Anyway oracle sucks with this modification . First it has no justification event oracle didn t bother to provide one . Second as they write themselves : This change of default-value may cause RMI-based applications to break unexpectedly . Yes That s the oracle we so painfully know SUN we miss you so much Comment : @wrzasa : the justification could be this vulnerability https : cve.mitre.org cgi-bin cvename.cgi name CVE-2013-1537 . The other vendor mentioned is likely this one http : www-01.ibm.com support docview.wss uid swg21640058 . Comment : The RMI Tutorial does not yet mention the useCodebaseOnly property . Every little hint there would help people getting not confused why the sample is not working - just like me . Please update the tutorial to keep the high quality there .

Currently I m doing this : .. . .. . Server .. . .. . Client .. . .. . The registry on the server has only one use to link-to the single server object . I figured I might just as well do this on the server : .. . .. . But then how would I connect to the server object from the client .. . Answer : The RMI Registry exists to solve the RMI bootstrap problem which is simply that you can only get a remote stub via a remote method call and to perform a remote method call you need a remote stub . The Registry reference provided by LocateRegistry.getRegistry solves this problem and is used internally by Naming.lookup if you are using that API . Note that this stub isn t obtained via a remote method : it is synthethized locally using the host : port you provide . If they aren t correct you won t find out until you use the Registry stub . .. . .. . You have several choices to solve the RMI bootstrap problem : .. . .. . 1 . Use the RMI Registry . 2 . Use an LDAP server via JNDI with the LDAP provider . 3 . Use UnicastRemoteObject serialize the stub obtained when you export the object and use a shared file or a socket or sneakernet to make the stub available to clients . 4 . Use RMI Activation serialize the stub obtained when you registered the activatable and distribute to all clients in a file along with the client application . From the point of view of stub distribution this is a lot simpler than 3 because the stub remains constant for the life of the application whereas in 3 you have to redestribute the stub on every export . You can see that the Registry is certainly the simplest option . Note that you only have to use it to solve the bootstrap problem Once you have a stub your own application remote methods can return further objects : you don t need more than one remote object in the Registry . You can consider that as a remote object factory . Comment : I ve come upon this problem again stackoverflow.com questions 11399408 http : stackoverflow.com questions 11399408 simple-entry-point-for-single-rmi-service and this time can t use the registry . I could use method 3 but if the client has the interface and host port of the service can it maybe synthesize a stub itself Comment : @BartvanHeukelom In theory yes in practice not really . Why can t you use the Registry", "Question : I have a requirement that the RMI client needs to get all remote objects registered in a remote RMI registry . First question I know there is a method of registry.list that returns all names of the objects .

Shall I traverse the names and use a try-catch statement trying to instanced each remote objects Second question how can a client gets noticed if a new object is registered In my requirement the servers will dynamicly registered new objects in to registry and the client needs to get updated and access the new objects sooner . Shall I just use a thread to periodically list all names to find out new objects Please note that the remote objects are to be exported from different nodes but not from a same node . I know if they are from the same node possibly I can use the call-back feature called from one of the instanced remote-object . .. . Answer : How can RMI client sees and get all dynamic remote objects registered in a registry By calling Naming.list or Registry.list . .. . .. . I have a requirement that the RMI client needs to get all remote objects registered in a remote RMI registry . See above . How do I get the objects of exactly the type I want implementing the interface that I want supposed that there are also other kinds of objects registered as well Shall I traverse the names and use a try-catch statement trying to instanced each remote objects Just traverse the names returned by list lookup each one and use instanceof to determine whether it is of a type you need . If the Registry contains stubs you don t have all the necessary classes for at the client you ll need to catch ClassNotFoundException . An easy way to do all this in fewer steps is via the JNDI listBindings http : docs.oracle.com javase 7 docs api javax naming Context.html listBindings java.lang.String method . Second question how can a client gets noticed if a new object is registered It can t . There is no listener system defined for the RMI Registry . The client will have to poll . In my requirement the servers will dynamicly registered new objects in to registry and the client needs to get updated and access the new objects sooner . Shall I just use a thread to periodically list all names to find out new objects Yes . Please note that the remote objects are to be exported from different nodes but not from a same node . You ll find that difficult to arrange as you can only call bind and friends from the same host as the Registry . You ll have to organize some intermediate remote objects to do the registering for each non-local node . I know if they are from the same node possibly I can use the call-back feature called from one of the instanced remote-object . Being from the same node isn t a precondition for that . You can do RMI callbacks in any topology where firewalls don t get in the way . Comment : Thank you for the clear answer . It helps Comment : An even easier way without the ClassCastExceptions is via javax.naming.Context.list method which returns an enumeration of pairs name class-name without retrieiving the objects . Comment : When I tried to look into the usage of javax.naming I found the following interface : javax.naming.event.NamingListener . From the description it looks like it can be used to listen to the event of naming changes like adding a name etc . Is this applicable to my requirement Comment : I tried javax.naming.Context.list but do not know the reason why the getClassName always return java.lang.object rather than the actual running class name.. . And if I tried listBindings it always return com.sun.proxy . Proxy where is a number... . Comment : I ended up with the solution of try-catch to catch the ClassCastException and ignore it . It does not look a good solution but I don t know why both Context.list and Context.listBindings do not return the real class name . Even if I tried the method of object.getClass .getName it returns the name of Proxy . I think I will post another question in detail of this and feel free to comment on that . Thank you any way", "Question : If i m creating the RMI registry from command-line the client has no problem in binding objects to the registry . However if i m starting the RMI registry using ProcessBuilder it s giving error . This is my code for creating rmiregistry using ProcessBuilder .. . .. . The error that i m getting for using ProcessBuilder when I m trying to bind to my own RMI registry .. . .. . node func is an interface .. . .. . Any ideas .. . Answer : The exception is occurring because the rmiregistry application doesn t know where to load classes from . When you attempt to bind an object in the RMI registry the registry downloads the class definition for that object . The correct way to handle the problem is to set the java.rmi.server.codebase property .. . .. . right-click on your project- run as- run configuration- Arguments- VM arguments . The property requires that a directory path be terminated with a forward slash like so : .. . .. . -Djava.rmi.server.codebase file : workspace location folder .. . .. . You may also be having trouble if the workspace location variable is a relative-path and the rmiregistry application was not started in the same directory so the relative-path is not correct for it . If you either make the path absolute or start the rmiregistry in the appropriate directory the ClassNotFoundException should go away . See the tutorial on the java.rmi.server.codebase http : docs.oracle.com javase 6 docs technotes guides rmi codebase.html property for a little more detailed information . Hope it helps . Credits to this guy http : stackoverflow.com questions 3629568 rmi-server-exception Comment : file : codebases only work properly if all clients are running in the local host as well . There are other ways to make the Registry work that don t involve the codebases for example specifying a CLASSPATH env var or classpath argument when running it . Comment : No that s not what I meant at all . What I said was there are other ways to make the Registry work that don t involve the codebase . Please don t attempt to translate on my behalf . Comment : Those methods have nothing to do with OP question which was something like i have this error how can i solve it and not how can i create a rmi registry otherwise my initial answer would be different . Comment : The OP s question is how to fix his Registry problem . He can do it with the CLASSPATH environment variable with -J-Dclasspath with the codebase feature or with Locate.Registry.createRegistry . These are all valid solutions to the OP s problem and none of them is excluded by anything in his question . The problem with your answer is that you presented only one of those methods as the correct way you didn t mention the issue with file : codebases that I raised you subsequently conflated nearly all of them as codebase features when they aren t and you misrepresented that as my comment . Comment : Codebase is actually for dynamic loading of remote resources i don t know where you get that codebase is for local clients but it s not like that you just said it you can define the codebase feature in the class path it s exactly what i said in response to your first comment it is still a codebase if you don t like it you can always add your own response thanks for your comments docs.oracle.com javase 6 docs technotes guides rmi http : docs.oracle.com javase 6 docs technotes guides rmi codebase.html", "Question : I am programming a simple client-server application using Java-RMI . I would like to know when all clients died in order to shut the server down . After having done some research on the web I found out that I could make my server implement the Unreferenced interface and define the unreferenced method . But this seems not to work and I think it is because the server is bound to the RMI-Registry which probably holds a reference on it . Does anybody have an idea of how I could get notified when all clients crashed in my case Thanks .. . Answer : I think it is because the server is bound to the RMI-Registry which probably holds a reference on it . You are correct the RMIRegistry also counts as a client for DGC Unreferenced purposes . Comment : So how would you check whether the clients have crashed in my case I am using a workaround which pings them at defined intervals but that is less reliable in my opinion since the client application may have crashed but the client host could still be running.. . Comment : That s the only way . Unless you have the object that s bound in the Registry be only a kind of Login object that returns per-client Session instances that aren t bound in the registry . When Session.unreferenced is called its only client has gone so it can do whatever it wants about that such as unexporting itself . You don t really care if the Login object has no clients . The distinction between client has crashed and client host has crashed doesn t seem relevant to me . What you are interested in is the health of the entire system including the client . Comment : Interesting . Your approach is really a smart way to do it . But I think will stick to my ping-based approach for this project . Thanks for clarification . Comment : @Jean Gauthier Sure . The Session approach has a lot of other things going for it such as automatic per-client state if you need that . But it s your design .", "Question : I write a simple RMI application .

Why it is allowed to the Client to unbind the Name in the remote Registry A evil person can do this with a modification of the Code and all my other Clients cann t connect to my Server because the binding was removed . Is there a possibility to deny this maybe in the Java policy .. . Answer : This can only happen if the client is running in the same host as the Registry . If you are having security problems wth your own clients you have a much bigger problem than anything RMI can solve for you .", "Question : So the problem is I have some server code that will allow a Client to call functions on it using rmiregistry .

However I keep on getting this same error : .. . .. . I know the only reason I m getting this error is because the rmiregistry can t find the server object . Some guidance would be appreciated .. . Answer : That s not a real HTTP URL . It s a directory name with http : stuck in front of it . You need to use a real http : URL with a real HTTP server . Or FTP . You can use a file : URL but then you re more or less stuck within a single host in which case you don t actually need the codebase feature at all . And if you do use a file : URL it has to be intelligible to the Registry and the client which again means either they re all in the same host or it names a shared directory that the Registry and client can see . NB Don t specify the codebase to the Registry or the client unless it exports remote callback objects : only to the server JVM Comment : My mistake I had it down as a file : URL - pasted the wrong clipboard . Which is what I want . What exactly do mean by specifying the codebase to the server JVM Comment : Specifying the codebase -Djava.rmi.server.codebase .. . . You should only specify that argument to the server JVM or more generally to JVMs that export remote objects that need the codebase .

Answer : The exception is occurring because the rmiregistry application doesn t know where to load classes from . When you attempt to bind an object in the RMI registry the registry downloads the class definition for that object . Some of the other answers are telling you to get around this by setting the classpath for the rmiregistry app so that it has the class definitions when it is started and doesn t need to download anything but Sun s Java RMI tutorial explicitly says not to do this http : java.sun.com docs books tutorial rmi running.html . I suspect this has the potential to cause conflicts between the version of the class in the registry and the class on the server . The correct way to handle the problem is to set the java.rmi.server.codebase property as you were trying to do . The property requires that a directory path be terminated with a forward slash like so : .. . .. . You may also be having trouble if the workspace loc variable is a relative-path and the rmiregistry application was not started in the same directory so the relative-path is not correct for it .

A class classes can not be found at the url provided . Make sure that the url is formed correctly and all needed classes are on the classpath . When a remote object is marshalled by RMI whether as an argument to a remote call or as a return-value the codebase for the stub class is retrieved by RMI and used to annotate the serialized stub . When the stub is unmarshalled the codebase is used to load the stub classfile using the RMIClassLoader unless the class can already be found in the CLASSPATH or by the context classloader for the receiving object such as an applet codebase . If the Stub class was loaded by an RMIClassLoader then RMI already knows which codebase to use for its annotation . If the Stub class was loaded from the CLASSPATH then there is no obvious codebase and RMI consults the java.rmi.server.codebase system property to find the codebase . If the system property is not set then the stub is marshalled with a null codebase which means that it cannot be used unless the client has a matching copy of the Stub classfile in the client s CLASSPATH .

A Registry implementation may choose to restrict access to some or all of its methods for example methods that mutate the registry s bindings may be restricted to calls originating from the local host . If a Registry method chooses to deny access for a given invocation its implementation may throw AccessException which because it extends RemoteException will be wrapped in a ServerException when caught by a remote client .

Answer : trying to bind an RMI server running on different vm XP IP : 192.168.133.3 .. . .. . Stop right there . You can t do that . You can only bind an RMI server to a Registry running in the same host as the agent that is doing the bind . Note that that does not necessarily mean the same host as the remote object itself is running in .

Before I continue I have to say that I ve been maintaining for almost a year our previous software which was written in Netbeans Platform but it has so many performance issues and so many bugs some of which it seems tied to the platform itself -- i.e . plugins not updating with no apparen reason that both me and my company kinda lost faith in Netbeans Platform but on the other side I can t seem to figure out a good way to start digging in Eclipse RCP . Of course mantaining that software means that I m already experienced in Netbeans Platform while I m at Hello World level with Eclipse RCP . On top of that I guess I m going to use JavaFX 8 which I have to learn as well since it seems it s the new de facto standard in Java GUI . Basically my software should handle a local SQLite or JavaDB or similar database of customers with various data to be sent via Ethernet to other devices . So has anyone experiences with one or the other And if someone s into Eclipse could gift me with some updated tutorials for Eclipse 4 RCP before I start buying books Thanks anyone .

The project is a fresh start so I m going to pick the latest version anyway . .. . Answer : Depends on your choice of UI toolkit eclipse is SWT and netbeans is pure swing therefore pure java . I have not worked with eclipse but I have been doing Netbeans plugins for nearly three years . Netbeans modular programming is pure pleasure like no other I know . Which Rich Client Platform to use http : stackoverflow.com questions 579109 which-rich-client-platform-to-use .. . .. . JSR 296 has been postponed to Java 9 after being postponed from java-7 to Java 8 . So I wouldn t wait on that . Spring RCP is dead long time ago . The author of the above post seems to have preconceived notions about Netbeans RCP s approach . Netbeans has already implemented both JSR 296 JSR 277 long time ago and their implementation is time tested nearly 15 years now . At the end of the day it boils down to what you are trying to do . But Netbeans RCP is a great tool and is used by many customers . FedEx and US airforce are the ones that come to my mind . Listed below is netbeans showcase that lists all the existing users of the RCP . It may be a bit out of date IMO . https : platform.netbeans.org screenshots.html .. . .. . Update .. . .. . There was one more thing I wanted to write but found it hard to gather myself at the bar last night : . A while ago I tried to convert SquirrelSql to use JavaFX but as with all my other ideas I lost interest midway . I found it surprising that I could just use the JavaFx s sorta kinda MVC with JBoss weld CDI and I really liked programming MVC in Java Desktop UI world .

Answer : I m working with evaluation license of JxBrowser and I m trying to integrate it into a Java application based on the Netbeans Rich Client Platform as a TopComponent . The code compiles but the JxBrowser window comes up blank are there examples of such integration or diagnostics that can help since the JxBrowser library is not opensource and so it is hard to debug the behavior . Thanks . Comment : Could you please provide more details about the issue . How you embed JxBrowser library into this Netbeans Rich Client Platform as a TopComponent . I suppose you use default rendering mode which is heavyweight rendering mode . Does Netbeans Rich Client Platform allow embedding heavyweight components . To check this you can try embedding java.awt.Canvas and see if it works . If Netbeans doesn t support heavyweight controls then you can try lightweight rendering mode .

If I simply copy and paste a it works fine and Netbeans doesn t throw an exception . So this seems to be coming from me typing in incomplete tokens . How can I resolve this .. . Answer : You need to ensure that tokens are created for all possible input sequences . The most straightforward way to do this is add an ERR CHAR rule to the end of your lexer . This allows the syntax highlighter to work and defers reporting of the error to the parsing phase .

To do this right-click your NetBeans application project node and select the Properties menu item . In the properties panel select the Libraries category . In the Platform Modules list expand the platform and check both the Auto Update Services and Auto Update UI nodes . This will add the Plugins menu item and coresponding UI elements Plugins panel .

You can still create your own layer.xml file and change the order of the toolbars in there . Just make sure that your layer file is being referenced in the manifest . At Runtime all the layers will be merged together - including the one that you manually create and the one derived from the annotations" ] }

Comment : Adding JSDoc comments really helped . I even made a dummy file containing object layouts I could reference later on and Komodo would autocomplete them perfectly .

The code-completion features seem to work pretty well for standard python modules however it doesn t know anything about Django modules . Is there any way to configure Komodo Edit to use Django modules for autocomplete as well .. . Answer : By sure Django is on your python path and Komodo should pick it up . Alternatively you can add the location of Django to where Komodo looks for its autocomplete . Comment : It was already on my python path could import django stuff via plain old python shell however komodo didn t know about it . Manually adding the dist-packages folder fixes it though . Comment : @TM - are you sure you have added the same Python which python in shell in Komodo s preferences as well Komodo internally uses that Python s sys.path which would obviously include dist-packages as well .", "Question : I got a real problem with Komodo Edit v8.5.3 : I use XAMPP XAMPP v1.8.3 PHP : 5.5.6 to provide a local hosted server for Komodo . .. . .. .

Answer : Komodo php autocomplete didn t work for me too . My situation might be different but I m sharing for the next Googler to visit . I installed Komodo before php5 . Whoops . Installing php wasn t good enough I had to also delete the config files in .komodo-edit or whatever folder it created . That still wasn t enough I also had to delete the .komodoproject file I was working on as well .

I use Django a lot for backend web development and one thing I noticed is code intelligence and auto completing doesn t seem to be working . I ve been using Django 1.9.7 on Python 3.5.2 . I m not sure what s happening but any advice on fixing this issue is appreciated . EDIT : I m using komodo edit version 10 and I m running on OSX Comment : I haven t updated to latest version of Komodo Edit yet but in Komodo Edit version 9 on Windows 10 autocomplete works just fine . Try to mention your OS and version of Komodo Edit . .. . Answer : It s not clear what you ve tried or whats not working ie . what did you type and what did you expect to happen so I ll just explain how Komodo does it s thing : .. . .. . When you open your Django project root in Komodo Places View Tabs Sidebars Places Komodo should start scanning your project to include that code in Komodo s code intel database . You may need to trigger a code intel event Ctrl + J in the editor to start the scan . You ll see in the notifications View Tabs Sidebars Notifications that Komodo is scanning your code . While this is scanning you can continue to use Komodo but there will be no Code Intel suggestions at all . When it has finished scanning you will get completions for the Python code Komodo found in your project . The above assumes you keep your Django code in your project root . If you don t you must open Preferences Languages Python Python 3 depending on whether you re using Python 2 or 3 scroll to Additional Python Import Dirs and add the location of your Django source trigger a Completions event same as above and wait for scan to complete . So that s pretty much it . If you re not getting ANY completions then you have to wait for Komodo to finish scanning . If you re only missing Django completions you have to make sure Komodo knows about your Django source and where it s located . Comment : I tried your first suggestion and this is the output from notifications : imgur.com a TxCHR http : imgur.com a TxCHR I also tried your last suggestion and I m not too sure which part of my django folder I need to go to . Is there a specific directory in my django project I need to direct komodo to Comment : re : image . The first notification says it s done scanning . Komodo is giving those warnings becuase there is no known symbol to complete on based on what you ve typed . Re : Django dirs . Sorry I have no idea . I don t do Django development . I just work on the Komodo core code . I watched this video from one of our previous developers https : www.youtube.com watch v TZP5T3ag118 and it looks like there should be bin include and lib dirs in your project .

Answer : Since you don t have access to an activity you could get the main looper and then post ui related tasks .

Answer : The method you are trying to hook is ambiguous as there are two SetOnClickListner method present in your class . So you cannot hook it directly as it will cause ambiguity errors . I think you are trying to modify one of avatarImage.setOnClickListener or writeButton.setOnClickListener methods . So you have to hook the method in which avatarImage.setOnClickListener or writeButton.setOnClickListener resides .

You need to make your app as boot start-up means whenever user restart mobile or device your app should automatically start s . 2 . Obviously you have to make app with no launcher mode as it s first activity and then call second activity as a service not as an activity . so basically you have to create something like this . .. . .. . and while calling service from your mainActivity define it like this . startService intent hideApp getApplicationContext .getPackageName .. . .. . hideApp use it outside the mainActivity . 3 .

Thus you just need to create an activity but I think that s not enough : you also have to make it a Launcher Activity in Eclipse or you can do that manually by adding the CATEGORY LAUNCHER intent filter . If it works when you push the app from eclipse to your testing phone the app will open automatically just like any other app . If this happens normally the app should also open inside Xposed .

I m sure this is due to XSS filtering in Safecracker are there any good solutions to get around this issue I m using 2.6.3 of Wygwam and EE 2.5.3 Safecracker 2.1 . .. . Answer : Take a look around line 1281 of system expressionengine modules safecracker libraries safecracker lib.php you will see this : .. . .. . This array seems to be here specifically to help with your situation wanting to skip XSS filtering on safecracker fields . The array is initialized around line 2612 of the same file : .. . .. . Therefore you should simply be able to add your field IDs to this array to skip XSS filtering like so : .. . .. . Keep in mind this is a REALLY REALLY BAD IDEA . At this point users can now add any arbitrary javascript to their wygwam field and you have effectively opened your website up to XSS attacks http : en.wikipedia.org wiki Cross-site scripting malicious users could hijack other users sessions and do whatever they like . Comment : Thanks Adrian that worked . The form is visible to only registered users . So XSS is mitigated but definitely still a possibilty . I will advise my client Comment : It s really about whether the entries are displayed to other users not whether the form itself is visible to registered users . For example if I can insert javascript which other users will view run that s extremely bad .", "Question : I m using ExpressionEngine but I want to make some content-management templates that are very simple compared to the control panel . Assume the following : .. . .. . Only the admin can register new members . Members are trusted people . All templates that use safecracker are only available to logged in members . Does using safecracker in this way weaken the security of the site Would there be any reason not to do this Is this the best way to get a very custom look for the content-management .. . Answer : I think the key to any security in EE is the strength of your passwords . If all your members are using strong passwords and keeping their storage safe there is no reason why safecracker should be less secure than the CP . Aother alternative to simplify your content-management for users is to use zoo flexible admin . http : devot-ee.com add-ons zoo-flexible-admin I use it for a lot of sites . Comment : Thanks .

The template includes a safecracker form . I have the safecracker form inside and if else statement so that if the url is group post title then the safecracker form loads an existing entry for editing .

Answer : Here s the answer http : expressionengine.com forums viewthread 216023 from the Expression Engine forums : .. . .. . The Safecracker tag already has built-in parsing to handle the edit new situation based on the value of url title or entry id .

I figure I m doing something fundamentally wrong so could someone point me in the right direction Thanks . .. . Answer : This is called variable collision - you re nesting entries which use the same variable tag names as those used by the parent tag in this case title and due to how EE s parse order http : expressionengine.com wiki Parse Order works the parent tag is winning every time . The solution is to put your above code into another template and embed that template http : expressionengine.com user guide templates embedding.html within your Safecracker form . Embeds are run at the very end of template processing after all of the other EE tags are parsed so you won t run into the same collision . Comment : Thanks Derek .

Basically my form allows logged in members to vote . I want them to be able to vote only once though so I set up a custom profile data field called voted which I want to set to true once they submit the form . Is this possible If so how Comment : Where are you storing the votes Are you storing individual votes or just incrementing the tally If you store the votes in a votes table then you can store the member id of the voter as well . This has the additional benefit of allowing you to not have to add another custom member field every time you need to have another election contest . You may also wish to evaluate some of the voting add ons that exist for EE . At the very least you will learn how this sort of thing has been handled before . .. . Answer : SafeCracker has an extension hook called safecracker submit entry end documentation http : expressionengine.com user guide modules safecracker development.html id3 so you can build an extension which uses that hook then in that hook s method do what you need to do . Hint : that extension hook gets passed a reference to the SafeCracker object which is not documented .. . so when you first test out the extension simply print the object so you can see what it contains : .. . .. . If you re unfamiliar with developing extensions and for ExpressionEngine using the database class etc that s a whole other thing . I can post some links to get you started if that s the case . Comment : Thanks - that is helpful . I guess my question was more of a two parter and I think the question that needs to be answered first is whether or not you can set custom member field values or not .

Now obviously processing the geometry-shader after the fragment pixel-shader makes no sense but what I m wondering is why not put it before the vertex-shader From a software high-level perspective at least it seems to make more sense that way : first you run the geometry-shader to create all the vertices you want and dump any data only relevant to the geometry-shader then you run the vertex-shader on all the vertices thus created . There s an obvious drawback in that the vertex-shader now has to be run on each of the newly-created vertices but any logic that needs to be done there would in the current pipelines need to be run for each vertex in the geometry-shader presumably so there s not much of a performance hit there . I m assuming since the geometry-shader is in this position in both pipelines that there s either a hardware reason or a non-obvious pipeline reason that it makes more sense . I am aware that polygon linking needs to take place before running a geometry-shader possibly not if it takes single points as inputs but I also know it needs to run after the geometry-shader as well so wouldn t it still make sense to run the vertex-shader between those stages .. . Answer : It is basically because geometry-shader was a pretty stupid choice of words on Microsoft s part . It should have been called primitive shader . .. . .. . Geometry shaders make the primitive assembly stage programmable and you cannot assemble primitives before you have an input stream of vertices computed . There is some overlap in functionality since you can take one input primitive type and spit out a completely different type often requiring the calculation of extra vertices . These extra emitted vertices do not require a trip backwards in the pipeline to the vertex-shader stage - they are completely calculated during an invocation of the geometry-shader . This concept should not be too foreign because tessellation control and evaluation shaders also look very much like vertex shaders in form and function . There are a lot of stages of vertex transform and what we call vertex shaders are just the tip of the iceberg . In a modern application you can expect the output of a vertex-shader to go through multiple additional stages before you have a finalized vertex for rasterization and pixel shading which is also poorly named . Comment : Whether you like the name or not the problem with primitive shader is that the abbreviation PS would be ambiguous with pixel-shader . GS geometry-shader is at least distinct from PS pixel-shader VS vertex-shader HS hull shader DS domain shader and CS compute shader . Comment : @ChuckWalbourn : Yeah which brings me back to my conclusion. . if they d called Pixel Shaders fragment shaders we d be a lot better shape .

Answer : After every call to EmitVertex the contents of all output variables are made undefined https : www.opengl.org wiki Geometry Shader Outputs . Therefore if you want to output the same value to multiple vertices you must copy it to the output every time . Also note that each shader stage s outputs provide inputs only to the next stage . So if you have a GS and you want to pass a value from the VS to the FS you must have the GS explicitly pass that value through .

I know vertex shaders cant call EmitVertex but i have an output variable vert that will be used in the fragment shader will that also be undefined after each EmitVertex in the GS Comment : @MostafaWasat : I don t know how your shader is even compiling and linking properly then .

Every out variable becomes undefined after EmitVertex is invoked you might get away with only setting it once on one GPU but on another it will behave completely different . Comment : Thanks I was not aware of that . .. . Answer : You are using the incorrect function to establish a vertex attribute pointer for thickness . Thickness has type int and you are using glVertexAttribPointer .. . . That function is designed to convert your vertex data to floating-point and is only suitable for float vec N and matrix data types . To correctly give your vertex attribute a data pointer you need to use glVertexAttribIPointer .. . . That will leave integer data alone and pass it directly to your shader it is appropriate for u int and i u vec N attributes . You will notice there is one less parameter in this function-call and that is because floating-point normalization is not an option for integer vertex attributes .

Comment : @BrettHale I normalize them in the fragment shader . Comment : @datenwolf I have my bone matrices in my fragment shader . .. . Answer : The geometry-shader in OpenGL only has access to single triangles and not the whole mesh so the normal must be calculated from a single triangle . The usual solution to this problem is to calculate the normals once for each vertex and store them in vertex arrays for easy access . This turns out to be faster and simpler as you don t need to recalculate anything in shaders . Comment : There are adjacency primitive-types http : www.opengl.org wiki Primitive Adjacency Primitives that allow geometry shaders to access the vertices for adjacent lines triangles this information is pulled from the index stream so if you do not use glDrawElements .. . it will not work as expected .

I read you can use : layout location 0 out whatever and then you don t need the same names but this doesn t work for me giving compilation error : ERROR : -1 : 65535 : : storage qualifier not valid with layout qualifier id . I think this is due to me not having a new enough opengl version to support that syntax . I also read you can use the extension : arb separate shader objects but failed to find any examples of it being used . Any suggestions Comment : I read you can use : layout location 0 out whatever Taht doesn t compile because you re using GLSL 3.30 . That functionality was added in GL 4.2 and is also a part of the ARB separate shader object specification . So you could use it with 3.30 but you would also need to explicitly request the use of that extension in your shader https : www.opengl.org wiki Core Language 28GLSL 29 Extensions . Comment : Thanks but your other answer seems like the better approach . .. . Answer : You can in fact do this . But you need interface blocks https : www.opengl.org wiki Interface Block 28GLSL 29 to do it . Indeed this is one of the primary problems input output interface blocks were created to solve : .. . .. . This is your vertex-shader using an interface block for its outputs . Vertex shader inputs cannot be aggregated into interface blocks . Notice that the vertex-shader calls the member of the interface block whatever . That will be important soon . In your fragment shader : .. . .. . The fragment shader now has a complementary input block declared . In order for this to work the block must use the same name as the corresponding output block from the previous stage . And it must declare all of the same variables as the corresponding output block in the same order . Note again that the fragment shader refers to the variable as whatever . This will be important presently . If you took these two shaders and linked them together either directly or indirectly with separate programs https : www.opengl.org wiki Shader Compilation Separate programs they would work fine . Now it s time to see what the Geometry Shader would have to look like to fit between them : .. . .. . OK a lot of stuff just happened . The first thing you ll note is that we seem to have declared the same interface block twice . No we have not input and output interface blocks are in different namespaces . So it s perfectly fine to declare an input interface block with the same block name as an output one . The input Data matches up with the output Data from the vertex-shader . The output Data matches up with the input Data for the fragment shader . So the interfaces match . Now you might notice that we declared these blocks differently . The input block has a tag vertex input while the output block has vertex output . This is not like a struct variable being declared after a struct declaration in C C++ . This name is what is known as the interface block s instance name https : www.opengl.org wiki Interface Block 28GLSL 29 Syntax . This is very important . Why Because it allows us to scope names of interface block members . Blocks declared without an instance name globally scope their members . This is why we could refer to whatever in the VS and FS with just that name . However since the GS needs to have two separate whatever variables we need some way to differentiate them . That s what the instance name is for . By giving the block an instance name we must prefix all references to that variable with that instance name . Note that the blocks across interfaces are matched by the block name . That is the input of the GS matches the output of the VS because they re both named Data . The instance name is only used within a shader to name-scope members . It does not affect interface matching . Lastly you ll notice that the GS s input variable is not an array . It is instead the instance name of the interface block which is arrayed . That s how interface blocks work in the GS and tessellation shaders that take arrayed inputs outputs . Given this definition you can slip this GS between the VS and FS without having to change any of them . So you don t have to modify the VS or FS code at all obviously besides the use of interface blocks . Comment : Perfect thanks . I had to add a to the in and out interface blocks in the vertex and fragment shaders although that was only a minor issue .", "Question : For instance if a glDraw call drawing GL TRIANGLES reads a set of VBOs that specify vertices A B C D E and F in that order then one would expect that in one invocation of the geometry-shader the following would be true : .. . .. . gl in 0 describes A .. . gl in 1 describes B .. . gl in 2 describes C .. . .. . And one would expect that in the other invocation the following would be true : .. . .. . gl in 0 describes D .. . gl in 1 describes E .. . gl in 2 describes F .. . .. . And so forth . But I don t see that being clearly guaranteed in any documentation I m finding . I suppose that if the vertices were arbitrarily reordered by OpenGL in a way that changed their CW CCW ordering then a lot of people s normal-finding code and other such things would probably be failing . But maybe something like this would be allowed for instance : .. . .. . gl in 0 describes B .. . gl in 1 describes C .. . gl in 2 describes A .. . .. . Can OpenGL do that reordering or is it guaranteed not to .. . Answer : I m using the OpenGL 4.5 core profile specification https : www.opengl.org registry doc glspec45.core.pdf here but what I say is basically true also for earlier versions . The exact wording and the locations of the statements might be different for earlier versions especially before 4.3 as the spec was totally reorganised in that version . From section 2.1 Execution Model my emphasis : .. . .. . Primitives are defined by a group of one or more vertices . A vertex defines a point an endpoint of a line segment or a corner of a polygon where two edges meet . Data such as positional coordinates colors normals texture coordinates etc . are associated with a vertex and each vertex is processed independently in order and in the same way . The only exception to this rule is if the group of vertices must be clipped so that the indicated primitive fits within a specified region in this case vertex data may be modified and new vertices created . The type of clipping .. . .. . This basically already guarantees that it can not re-order the vertices . However we can find more specific language for that . Let s concentrate on the example case of triangles for now . Section 10.1.8 Separate Triangles states .. . .. . Separate triangles are specified with mode TRIANGLES . In this case the 3i + 1st 3i + 2nd and 3i + 3rd vertices in that order determine a triangle for each i 0 1 .. . n - 1 where there are 3n + k vertices drawn . k is either 0 1 or 2 if k is not zero the final k vertices are ignored . For each triangle vertex A is vertex 3i and vertex B is vertex 3i + 1 . Otherwise separate triangles are the same as a triangle strip . So it is absoultely clear what order the vertices of a triangle are . So let s get to geomerty shaders in section 11.3 : .. . .. . After vertices are processed they are arranged into primitives as described in section 10.1 . The order defined above is completely relevant here . Now the part about triangles from section 11.3.1 Geometry Shader Input Primitives : .. . .. . Triangles triangles .. . .. . Geometry shaders that operate on triangles are valid for the TRIANGLES TRIANGLE STRIP and TRIANGLE FAN primitive-types . There are three vertices available for each program invocation . The first second and third vertices refer to attributes of the first second and third vertex of the triangle respectively . This together with the quote from section 10.1.8 makes it pefrectly clear that the exact order from the draw call is gauranteed to appear in each geometry-shader invocattion . However the order of different geometry-shader invocations is of course undefined as stated in section 7.12.1 Shader Memory Access Ordering : .. . .. . The relative order of invocations of the same shader type are undefined . A store issued by a shader when working on primitive B might complete prior to a store for primitive A even if primitive A is specified prior to primitive B . This applies even to fragment shaders while fragment shader outputs are always written to the framebuffer in primitive order stores executed by fragment shader invocations are not . But this is what s to be expected from a parallel architecture anyway so no surprises here .", "Question : I m stuck with geometry shaders in OpenGL - c++ programming .

This adds an offset.. . but it adds the offset in clip space which is probably not what you want . Add the offset in your vertex-shader or do the perspective projection in your geometry-shader .

It gets an input array of vertices from vertex-shader invocation s and can access up to n-many vertices at a time depending on the primitive type . For a line n would be 2 for line-adjacencey n would be 4 . The vertex-shader is evaluated at least once for each of those vertices before the GS runs . Comment : @AndonM.Coleman So the geometry-shader will invoke on every two vertex invocations Does that mean that my list of points is used as data for the lines Comment : Do you mean GL ELEMENT ARRAY BUFFER If so then yes . Those vertices in-order will be the input to your geometry-shader . Keep in mind there is a transform cache so if you share vertices in your lines like 0 1 2 1 2 0 the vertex-shader might only run 3 times later invocations of the GS will use the cached output for vertices 1 2 0 . Comment : @AndonM.Coleman Thank you This information was helpful", "Question : I am working on a project where and I am simplifying a little .. . .. . I need to calculate cross sections of 3-dimensional shapes and render them . For example I may have a list of tetrahedrons each tetrahedron consists of 4 vertices or a list of triangular prisms each triangular prism consists of 6 vertices or a list of n prisms each n prism consists of 2 n vertices etc . I want to calculate two-dimensional cross sections of them the two dimensional cross sections would be made up of triangles and render the cross sections . The simplest and most efficient way I have thought of for this is sending the 3D vertices to the vertex-shader then sending them to the geometry-shader and taking the cross sections there . However in order to do this the geometry-shader would need to take in primitives with 4 points or 6 points more than 3 points . This is a problem because to my knowledge the geometry-shader can only take in points lines and triangles and nothing with more points . I could solve this by storing the attributes of several 3D vertices in a single GLSL vertex but this would be very complicated and inelegant . Question : .. . .. . Is there a way for the geometry-shader to handle primitives of custom lengths similar to the patch primitives used in tessellation shaders I will still only be outputting triangles from the geometry-shader . Note : By the way I am kind of new to OpenGL so tell me if I got any of the terminology wrong . .. . .. . Edit : By cross section I mean any cross section along a plane that is not necessarily aligned with the bases of the prisms . There will therefor be a variable number of triangles resulting per cross section . For example a plane may intersect a tetrahedron at 0 3 or 4 points and the geometry-shader ideally would take in 4-point primitives and output either 0 1 or 2 triangles . Also my question has nothing to do with the actual cross section calculation . I am asking specifically whether there is a way to use a primitive with more than 3 points as an input to the geometry-shader . Finally this is the second question I have posted so I don t know whether I have formatted things properly . Sorry if I haven t Comment : What do you mean by cross section I think a diagram might help to understand what you mean . If your cross-sections are always across the prism then you re effectively just repeating the end geometry of the prism . .. . Answer : Is there a way for the geometry-shader to handle primitives of custom lengths similar to the patch primitives used in tessellation shaders If you want to work with a geometry-shader there are two straightforward ways to achieve this : .. . .. . 1 Use triangles adjacency as input primitive type instead of triangles which provides you with 6 vertices per geometry-shader invocation . Usually this is used to provide adjacency information at the three edges of the current triangle but you can provide whatever data you want via the element buffer . See here for a quick overview of geometry shaders . https : www.opengl.org wiki Geometry Shader .. . .. . 2 Use points or anything else for that matter as input primitive type and make use of the built-in variable gl PrimitiveIDIn . Create a shader-storage-buffer texture buffer or simply a texture to hold your geometry data and use this primitive ID to access the data for the current shape . If you have shapes with varying vertex count you can use an additional index-buffer that you access with the primitive id . Then you access the vertex-buffer at the offset you got from your index-buffer . The second solution is obviously the more flexible one . A third option is to not do this in the geometry-shader in the first place . You execute a compute shader say one invocation per shape you have bind writeable shader storage buffers for vertices and indices do your cross-section calculations in the shader as usual store the resulting geometry in the buffers and then draw the cross-section geometry as usual . This way you do not need to take the detour through the vertex-shader which transforms vertices you do not want to render .", "Question : I currently have some VAOs and an index list . The idea is to process groups of 4 elements in the geometry-shader . The way of picking the groups is if I have the list 1 2 3 4 5 6 7 8 .. . then the groups would be 1 2 3 4 5 6 7 8 .. . . After spending several hours of coding I realized that geometry shaders don t accept 4 vertex primitives . I would like to know if there is a way around it . Maybe choosing a provoking vertex and appending the other 3 to it as added properties in the vertex-shader stage I doubt that s possible though . Comment : You can combine your 4 vertices to one big vertex and pass them as points to the geometry-shader . Comment : I think that s easy when you don t have an index list . In that case I would just put the required values in the order that I want and set the VAOs to read bigger chunks . In the case of an indexed list which is necessary in this situation how would that be done .. . Answer : Geometry shaders do accept primitives with 4 vertices as input : GL LINES ADJACENCY . This primitive mode might be meant for lines where you need the two neighboring segments for each segments but it is not limited to any particular use-case - it just provides 4 vertices as input and can be used as such it could also be used to emulate the deprecated GL QUADS primitive mode with geometry shaders . Comment : Thank you I thought GL LINES ADJACENCY required some special properties of the rendered mesh . So after all it s just a simple 4 input vertex to the GS and the proper meaning of GL LINES ADJACENCY may be given in later stages of the pipline which is not my case since I m doing transform feedback . Comment : @Gonzalo : Actually there is no proper meaning later down the pipeline . The only thing that can give a geometry-shader s input primitive any meaning is the geometry-shader itself . The adjaceny meaning is only fulfilled if you actually supply the information of the neighboring vertices per input primitive . But the GL really won t care what exactly you put there and if some other primitive might share the data or not . If you really need adjacency this means that you have to redundantly specify such neighboring infos per input primitive . Comment : Oh right . I was thinking of lines arriving to the rasterizer but as you say geometry-shader can output something different from lines with adjacency . So the name GL LINES ADJACENCY is just a suggestion of how to use that primitive mode though not limited to adjacency purposes . Thank you Comment : @Gonzalo : The geometry-shader not only can output other primitives than lines with adjacency it also absolutely must do so . The rasterizer and further stages of the pipeline cannot handle adjacency primitives at all for obvious reasons . Adjacency primitves are only valid as input for the geometry shaders . It is also not possible to draw such primitives if no GS is in use . Comment : @Gonzalo : actually I might be wrong with my very last statement in the previous comment . It seems like one can draw adjacency primitives without a GS the adjacent vertices are just ignored .", "Question : I programming with C++ + SDL2 + GLEW + Opengl 4.1 a small voxel game a little bit like Minecraft . I am trying to optimize the voxel rendering where I can . I slide the world into chunks and this chunks into blocks . Each chunk contains 16x16x16 blocks . Now if a edit a chunk remove place a block I rebuild the complete chunk and the neighbor chunk and upload it with vao s and vbo s to the graphic card . Now to minimize the vertex data I have to transfer from the cpu to the gpu I use geometry shaders . First of all is that a good idea I mean every frame the geometry-shader has to calculate the primitive for each voxel face . However I programmed the vertex-shader so that I only have to pass one vertex for each block face . To make that possible I used a vec4 . The first 3 elements x y z I used for the block position and the 4 . Element w I used to indicate in which direction the face is showing . 0 means back 1 means front 2 means left 3 means right 4 means bottom 5 means top . Please ignore the UV and the normal for now . Further more I upload GLbyte s instead of GLfloat s . Is that a good idea What would be a better faster way Comment : Too bad you re not using 4.3 then you could run compute shaders to generate the chunks . Comment : Thanks I didn t knew the compute shader it seems to be another good approach . .. . Answer : You can test yourself but in general the geometry-shader will slow things down rather than speed things up . From what I understand AMD GPUs have a special case for geometry shaders which always output exactly 4 vertexes true in this case and the Intel GPUs can have fast geometry shaders relative to other GPUs but in general without the fixed output size optimization the different geometry shaders will have to be synchronized . So you may be hitting the fast cases here on some or many or most implementations but you would have to test . Consider that the vertex data might not be very large anyway : say 8 bytes per vertex or 32 bytes per face . You can even reuse the same index-buffer for all chunks e.g . 0 1 2 3 0xffff 4 5 6 7 0xffff . This transforms the problem into a very traditional time-vs-space tradeoff . You can either spend more time in the geometry-shader or spend more space storing the full vertex data . Is your program running into memory limits Or are you running into computation limits Test . Note that your geometry-shader could be written branchless . Instead of using if else you can just use an array to store the basis vectors for the output of faces in each direction .", "Question : I would like to attach a geometry-shader to my existing and working vertex and fragment shaders .

I just want that what ever was there earlier is passed from vertex-shader to fragment shader via geometry-shader so that I can manipulate the shader later . Currently the screen is just black .. . Answer : The core of your problem is that you didn t bother to check for compilation errors when you built your Geometry Shader . I know that because I see several syntax errors for it . In particular : .. . .. . Geometry Shader inputs https : www.opengl.org wiki Geometry Shader Inputs are always aggregated into arrays . Remember : a geometry-shader operates on primitives https : www.opengl.org wiki Primitive which are defined as a collection of one or more vertices . Each GS invocation therefore gets a set of per-vertex input values one for each vertex in the primitive type defined by your layout in qualifier https : www.opengl.org wiki Geometry Shader Primitive in.2Fout specification . Notice how you loop over the number of vertices in a primitive and use gl in i to get the input value for each vertex in the primitive . That s how you need to access all of your Geometry Shader inputs . And you need to write each one to its corresponding output variable then call EmitVertex . All in that loop .

The goal of the shader is to make the normal pass produce transparent pixels such that the object is invisible while the geometry pass will take each triangle redraw in the same place as the original but colored black .

Here is the code I currently have for the shader . Since all I m doing is taking the same triangles I ve been given and appending them to the triangle stream I m not sure what I could be doing wrong to cause nothing to appear . Anyone know why this is happening .. . Answer : I notice that you don t call triStrem.RestartStrip after feeding in 3 vertices of a triangle in your geometry-shader . This informs the stream that a particular triangle strip has ended and a new triangle strip will begin . If you don t do this each single vertex passed to the stream will add-on to the existing triangle strip using the triangle strip pattern : https : en.wikipedia.org wiki Triangle strip .. . .. . I m fairly new to geo-shaders myself so I m not sure if this is your issue or not I don t THINK the RestartStrip function is called automatically at the end of each geomerty-shader but have not tested this . Rather I think it gets called automatically only when you you reach the maxvertexcount . For a single triangle I would set the maxvertexcount to 3 not the 12 you have now . I also know it can be tough to get ANY shader answers so figgured I d try to help . Comment : I actually really appreciate this . I m not sure this will fix it as I opted to move in a different direction to get the effect I wanted without a geometry-shader but that is a very important piece of information about triangles and I ll be sure to remember it in the future .

Comment : Sure @Andon . I ve added them to the question . .. . Answer : EmitVertex invalidates all per-vertex outputs after it returns . The most obvious per-vertex outputs in this shader are : .. . .. . 1 . raster color .. . 2 . gl Position .. . .. . But you may not have realized that gl Layer is also per-vertex or which vertex this needs to be set for . .. . .. . gl Layer will be undefined for every vertex after the first in this shader . Some drivers will leave it untouched and simply work others will do anything they want with it and you cannot make any assumptions about gl Layer after EmitVertex .. . . You are playing with fire because it may not be the first vertex that defines a primitive s layer more on this later . .. . .. . To fix this re-write your geometry-shader this way : .. . .. . I would like to take this opportunity to point out that only 1 vertex in a primitive needs to have gl Layer set this vertex is called the Layer Provoking Vertex . Your shader assumes that the first vertex is the layer provoking vertex but this is implementation-specific . When in doubt the best solution is to cover all bases set gl Layer for all vertices . You need to check GL LAYER PROVOKING VERTEX at run-time to figure out which vertex defines your layer . If you do not want to do that you can write your shader the way I described above . Provoking vertex conventions are usually first or last but the way Geometry Shaders works leaves the possibility that any arbitrary vertex could define the layer GL UNDEFINED VERTEX and this is the case you should assume . Comment : See here https : www.opengl.org wiki Geometry Shader Which vertex for more details on this situation . It applies to viewport provoking vertices as well . Comment : I tried your code modifications to no avail I m afraid . But then I kept searching elsewhere and found the source was something far more mundane . A syntax-error in my texture parameters meant it wasn t clamping properly and the top layer was wrapping back around to the bottom when sampled . I understand per-vertex outputs far better now for future reference though . So thank you . Comment : @Andy : Ah gotcha . As I was writing this I had my doubts that it would fully explain your problem but it needed to be addressed . Understanding this may save you a lot of frustration down the line If you ve figured out a solution the best course of action would be to answer your own question . Even if it was something simple add the code that was problematic and an explanation of your fix and mark it accepted . This is how Stack Overflow is supposed to work .

I had to add-in a -I usr local include and -L usr local lib to the g++ call in order to build . Might headers and or libraries be getting retrieved from elsewhere such as a separate SDL2 framework 3 . The copy of g++ I had on my system was in reality clang which was provided by Xcode v7.3.1 and which I presume Apple had just linked to usr bin g++ .

Answer : From looking at the lexical cast documentation it appears that std : : string is explicitly the only string-like exception allowed to normal lexical-cast semantics to keep the meaning of the cast as straightforward as possible and catch as many possible conversion errors as can be caught .

Which is running a screen this is where the network runs : Comment : It would help if you could indicate which program crashes server or client and at which line . Comment : It s my client fixed my question in an edit . .. . Answer : You are not creating an OpenGL context anywhere and call SDL GL SetSwapInterval 1 which according to the source http : fossies.org linux SDL2 src video SDL video.c sets the error to No OpenGL context has been made current . And then in your void network : : send Player p you call SDLNet GetError for no apparent reason and get that error . I assume you should call SDL GL CreateContext http : fossies.org linux SDL2 src video SDL video.c after SDL CreateWindow . Comment : I assumed that this would fix the crash I get I was being naive . Any idea what could be behind the crash I certainly don t . Comment : Well to be honest mostly I try and help out but at the moment I don t have any time to devote to this . Your code has a lot of new calls and pointers and looking at it takes time . I don t wan t to sound impolite but why can t you use a debugger At least a stack-trace of the point of crash would help . Comment : @genfy I took a quick look at the client code you posted and well - you need to rework it a lot . Sorry for the criticism but it is terrible - you are using a global tmp assuming global since there is no declaration or definition which is being printed to and accessed in weird ways like tmp strlen tmp - 1 I am calling this weird because you will actually pass one byte before the start of tmp to strlen .

So can anyone state what could be the issue at either of these parts There is no error I just get muddled up images which I can notice are images just wrongly put together or not full images . Anyone needs more info just ask or more code I will put it up . Cheers . Comment : your tcp packets will get fragmented thus you have to read in small chunks like 1k . you can send the image in one piece but not expect it to come in one packet on the other side . Comment : Aa far as I am aware the recv acts in a similar way to send and waits for all of buffer to be sent before doing anything else . I think.. . However I did have it sending in 64kb chunks TCP max packet size and receiving these 64kb chunks and it was worse Comment : also do never use opencv s deprecated c-api . Comment : Yeah I read the IplImage stuff was deprecated but when searching for ways to allow an image stored as a simple memory block to be displayed it was all I could find . Could you offer guidance on another way to do it Comment : Mat m 720 1280 CV 8UC1 data and btw 1280 720 921600 which is also more than a 64k packet.. . .. . Answer : Try converting the frames from YUV to RGB . http : en.wikipedia.org wiki YUV lists how YUV formatted data is converted to RGB . You might also find readily available code to do that . Check the format of YUV data output from your camera and use the correct transformation . Comment : I was gonna concert to rgb server-side but I can do it on the client no bother ill give that a bash . I assume you are guessing that the data is arriving fine and its just the displaying I am having issues with Comment : Yes . But if you do the conversion at client-side you ll have to transfer more data over TCP because the yuv- rgb conversion expands data and it ll have an impact on the performance if you are concerned about the speed .

See this : stackoverflow.com questions 234724 http : stackoverflow.com questions 234724 is-it-possible-to-serialize-and-deserialize-a-class-in-c Bottom line is that you want to send the data that is in the vectors not the vectors .

Comment : You should provide aditional info specifically code expected results and actual results . Comment : You run a network sniffer and check if the app sends back responses . If it doesn t you run your app with a debugger and check where unexpected things happen that prevent it from sending back responses . If it does send responses but your browsers just don t see them then you can either blame a firewall or blame an incorrect implementation of the HTTP protocol by your app or blame an incorrect implementation of HTML by your app .

The error as you would assume is when I try and set p-data towards the bottom of the code . Any advice or corrections you have would be greatly appreciated .. . Answer : p- data points to a buffer which was already allocated by SDLNet AllocPacket -- you need to copy your string data into it rather than trying to replace where it points .

Comment : Sending the request kind is kind of correct but reading of the response is not . It does not take in account neither a response body of more then 1024 bytes nor chunked-encoding nor that the server will probably not close the connection immediatly after the response is done because keep-alive is active implicit with HTTP 1.1 .

See here for more information . http : stackoverflow.com a 228797 440558 Comment : Also you probably have undefined-behavior in your code . The data returned by c-str http : en.cppreference.com w cpp string basic string c-str is read only attempting to write to this array leads to undefined-behavior . Also if the length of the string is less than MAXLEN you might even be writing out of bounds once again leading to UB . Comment : when define ing numeric values surround the numeric value with parens to avoid any text substitution errors Comment : this is c++ code please remove the c tag .. . Answer : You re passing in request to the SDLNet TCP Recv function and telling that function that request points to a buffer of size MAXLEN . As request comes from casting away the constness from the buffer of an empty std : : string this is clearly wrong . You want a vector Comment : Thanks for the good comments .", "Question : I am trying to use the SDLNet TCP Send TCPsocket sock void data int len function part of the SDL net library and I am having a hard time figuring out how I could use this to send an int .

Comment : So what UDP packets can be split up and merged anywhere not just at space characters . It s your job to know where one piece of send info ends and the next begins . Comment : I did consider this actually . However I found it unusual to be able to replace the space characters with an underscore and it be transmitted in full instead of split up . Does the space character have any special significance in this case Comment : UDP datagrams are received intact or not at all .

It s a datagram protocol not a stream protocol . .. . Answer : This is not the fault of UDP it s go to do with the char being split up when using scanf . I m not a 100 sure about the details here .

I have been doing some analysis on some of the frameworks that will suite my needs .

This blog is an old one and I felt like tideSDK is promising So I would like to know whether tideSDK is production ready Or do we have any other options like tideSDK . .. . Answer : TideSDK is still in beta therefore it does not exactly provide what you are looking for . We are currently working on something new it is called TideKit . TideKit is a platform you can use to create native apps for web desktop and mobile from a single code base written in JavaScript . It also provides code hiding and everything you need to create a world-class native app for multiple devices not only desktop . If you are interested in TideKit follow us @TideKit on Twitter or watch our short video on YouTube http : www.youtube.com watch v aE7gN-d0GhU Comment : As of now I have few deadlines to meet.So If I go ahead with tideSDK in MAC then I can reuse source code to build the .exe in windows rite . At this point of time I am not worried about the deploying completely . I need to pass the .app and .exe files to my client so that they can use this app in their local machine to communicate with another app that we have already developed and deployed . Please correct me If I said something wrong As I have been not used to tideSDK . Comment : Yes using TideSDK you should be able to reuse your source code across Windows osx and ubuntu .", "Question : I have a project I have coded using TideSDK . What is the difference in purpose and support for platforms between TideSDK and TideKit Comment : This is not a StackOverflow question even if you edit it to be a question answer . It s a post for the product documentation instead . Please do not use StackOverflow to promote your product or project that s not what this site is designed to do . Comment : There are technical differences between the two pieces of software this is not promotion but valid question I am answering for our users to assist them in assessing differences in platform support . Comment : @KenWhite We have had this question come up in discussion on twitter and it this is about answering differences . Of course our documentation will spell what platforms we support but it will not clarify differences with other similarly named software which is what this question entails . I would appreciate if you could keep this in mind for those folks that will benefit from the answer i will prepare . Comment : I appreciate your opinion on this but we have folks that will be transitioning between the two types of software . We are making this point so that folks use either TideSDK or TideKit have a clearer understanding of the technical differences between these . We d like this question here to help them . Hope that clarifies this finally . Comment : Sorry but I still think this belongs on your own documentation pages . Voting to close . IMO this question appears to be off-topic because it is a product documentation post that should be on the product site perhaps as part of a FAQ section . .. . Answer : There are key technical differences between TideKit http : tidekit.com and TideSDK http : tidesdk.org despite the similar sounding name . TideKit is an application development platform for desktop web and mobile whereas TideSDK is a desktop SDK Software Development Kit . TideKit was developed by the same core developers that developed TideSDK . They went on to found CoastalForge http : coastalforge.com to create TideKit with the vision of creating for all screens and devices . From the source code of a single project an app can be built and packaged for each device bridging each language its user interfaces and capabilities . As of this date TideKit has been in development and is due to be released . Development can be following on Twitter at https : twitter.com tidekit .. . .. . TideKit is not a single tool piece of software UI or SDK Software Development Kit . It is a central hub for app development . TideKit combines remote software together with local software that you use on your system . Developers write code using their favourite text-editor and interact with TideKit through a CLI Command Line Interface or through interaction with the TideKit app . enter image description here http : i.stack.imgur.com cGX1f.png .. . .. . TideKit provides more than a single approach to development . In its simplest form it can be used in a similar way to TideSDK for app development but it has much greater capabilities . TideKit was designed to create ubiquitous apps for all screens and devices at one time . This is accomplished using CommonJS . You write your project code once then build and package it for virtually all operating systems and devices for mobile web and desktop . Development using TideKit is fully unified for client-server desktop mobile or web . The primary advantages are access ie developing in JavaScript instead of the core languages to get native features development speed everything can be created at a fraction of the time compared to developing for one platform lower development cost and more reach able to create for all platforms to monetize everywhere with a single effort . TideKit is for the whole of app development therefore it differs greatly in platform support that is summarized below . Despite these differences a TideSDK project may be migrated to TideKit with small changes in your code . TideKit .. . .. . Windows XP .. . Windows Vista .. . Windows 7 .. . Windows 8 .. .

Is it possible to add C or at least C++ JAVA code or Dll libraries to the solution 2 . Is it possible to make a package with html+js+css and native-code C C++ Java working in one executable file or executable + dlls There are already working solutions like CefSharp Awesomium but there is a problem to make external resources html css js embedded inside the project . I would like to hide my implementation from end users somehow . I ll appreciate any answer related to my questions . .. . Answer : 1 . We don t support C but yes to the rest . 2 . Again no C but yes to answer this question . Further explanation below : .. . .. . We ve developed TideKit to have a small and stable core so that the apps can be built up in a modular way with the functionality you want in your app . TideKit provides simultaneous extension in ObjC++ C++ Java and JavaScript for web HTML5 hybrid and native apps . Generally developers will consume modules without the need to write lower level code because the functionality already exists both natively and for HTML at the same time . So mostly it is about consuming modules and writing your app in JavaScript . Modules allow a project to be built for desktop mobile and web from a single base of code . TideKit is a uniquely develop once deploy everywhere platform with easy-to-use JavaScript APIs and CommonJS modularity . The best way to write TideKit apps is CommonJS . More than 60K modules of CommonJS functionality is available through npm and components registries . Folks familiar with nodejs will be at home with it . You can also write conventional JavaScript or easily migrate an existing TideSDK app . Automated packaging installers and distribution are part of our solution . There are packaging options that can provide bundled or network installs to take advantage of dynamic libraries for efficient runtime code to keep the amount of installable and distributable code to a minimum . TideKit has the capability to build in different ways from your project source to optimize for AppStore compliance or even highest HTML5 compliance . You can use it to build HTML5 or native apps for virtually any platform you wish to support . On the backend we have capabilities for the widest range of mobile and desktop operating systems and for web deployments . Beyond building your app simultaneously for multiple platforms you can also develop test and deploy your APIs from the same base of code . Our build service protects your code from exposure by encrypting and embedding the sources in a binary . Hope this helps . Comment : Thanks for this helpful info Comment : Well you have ruby so you could possibly get ffi to work and then run the dll through there : ffi example https : github.com ffi ffi wiki Windows-Examples", "Question : I have an app that functions perfectly outside of Tide . The app uses Flowplayer to load and play a video using HTML5 . It appears that when Flowplayer insert the video tag and sets the src attributes the path is prefaced by the namespace application id used in my app configuration . Is there a way to disable this Everything in my app is inside the resources folder so there is no need to include the application name in the path . Thanks H .. . Answer : @Ward Where we left TideSDK unfortunately it did not have support for audio video tags in HTML5 . The HTML parser within the webkit in that code does not handle this properly . We decided more than a year ago to put our energy into a broader effort for mobile web and desktop called TideKit that is due to be released shortly . http : youtu.be aE7gN-d0GhU .. . .. . HTML5 support is state-of-the-art including audio video so embedding is just as easy as using the tags . Working with anything HTML5 or creating apps with native capabilities and UI will be easier and better than ever . TideKit will launch with a CLI and an app to connect with our build service to optimize build s based for your app s requirements and where you want it to go . Any code you have in TideSDK can be migrated easily . Comment : Will there be any way to protect the videos from being easily copyable out of the app in TideKit", "Question : I need to know if TideKit will be able to stream live video and audio from device cameras and microphones . The Android and IOS APIs allow for this . I think Flex can do it . I asked about this on the Twitter page but I m looking for a more definitive answer . The one I got was TideKit is a development not a streaming platform but you could develop an app for that That s where TideKit comes into play which doesn t fully answer the question . The goal is to stream video from Android IOS cameras and audio from the device microphones to a media streaming server such as Flash Media Server or a Wowza streaming server using either RTMP or HTTP streaming from the app to the server . That or it would work if the stream were sent live in any other way to a server socket and then encoded for redistribution via a streaming server . They key here though is live rather than having to waiting for a video or audio file to become complete before sending it off to the server . I know it s possible with the APIs and I really hope TideKit will be able to do this because no other platform similar to TideKit and there are MANY can do this besides Flex . I ve poured through countless SDK documents . If TideKit can do this it will attract a lot more customers . Eagerly awaiting a response .. . .. . Thanks .. . Answer : @xendi Thank you for your question . TideKit is an app development platform . You can use it for any type of app development for mobile desktop and web . We ve purposefully kept the core of TideKit small . This is to ensure its core is extremely stable and that most functionality can can come through modules . Out of the box TideKit has core AV functionality on all platforms . Extension of this functionality is through TideKit modules that have operating-system implementations or from pure JavaScript modules . There are almost 100 000 modules of pure JavaScript functionality now available to you through existing repositories including NPM Bower and Component that can simply be consumed in CommonJS . When a TideKit or JavaScript module is installed it offers its APIs . This extends the APIs with those already available . Either way those APIs become available to you in JavaScript . You already have access to camera with TideKit . The rest is handling the streaming protocol ie RTSP RTMP HTTP etc . So there are a few ways to accomplish what you want with TideKit . 1 . Using a TideKit module that supports the streaming protocols by interacting with its APIs in JavaScript . 2 . Using a pure JavaScript solution from a repository together with TideKit that supports the protocols . 3 . Writing your own TideKit module that ties together with APIs of the operating systems . 4 . Writing the solution in pure javascript using TideKit s camera and network APIs . TideKit is new and has not yet formally launched . We are currently in a reservations mode . We will be delivering it first to those with reservations and it will be gradually rolled out . Demos are currently being prepared to demonstrate the speed and low barrier to development . When TideKit formally launches I would check for the availability of modules at that point for both TideKit and JavaScript implementations . Note that not all possible functionality in TideKit modules will be available with the launch . New modules will be releasing over time . As an aside TideKit also supports WebRTC in HTML5 so this could work together with TideKit s other capabilities for interesting possibilities . Comment : Thanks . I wasn t really worried about the protocols used for streaming out rather that through TideKit would I have access to live video and audio through the cams and mic on android ios without having to write any Java or Objective C . Is that correct I already reserved a seat a while ago . Comment : @xendi Yes you get direct access to the device s microphone and camera in JS through our APIs so no ObjC or Java . We are also here to help point you if you have questions along the way .", "Question : I am interested in creating a desktop application using HTML5+webkit and I d like to be able to build a stand-alone executables for various target platforms like a .exe file for Windows and a .dmg image for Mac OS .

Desktop Builds https : blog.tidekit.com post from-a-desktop-perspective-tidekit-for-tidesdk-developers Comment : Thanks it s always nice to get an authoritative answer i.e . from a core team member and BTW welcome to StackOverflow : Your product looks very appealing though the hype about HTML5 scores seems moot as one can grab the latest snapshot of webkit chromium bundle it and get 517+ and I wish you and your customers all the best . As for me however I m really not interested in any commercial solutions in this space so I think it s truly unfortunate that continuing development of TideSDK as an open-source project was not financially viable . Comment : @iX3 In fairness TideKit is not a repackaging of chromium but has extensive APIs to build web mobile and desktop apps using HTML5 hybrid and native technologies . Its key feature is the ability to create for virtually all platforms from a single-source of code . The recent 505 HTML score we celebrated is significant . Currently no modern browser wrapper node-webkit or atom implements a score this high at present . We are going further of course . Compliance is a high priority to ensure everyone can work with HTML5 s full capabilities . Demos are coming next .

Answer : TideSDK is capable of extension with modules that can be compiled and included in its runtime . It was written to be extended but I would recommend waiting for TideKit .

How large is the smallest offline executable you can create for Windows respectively Mac including running HTML content in a web view Other solutions like NodeWebKit include a portable Chromium which makes the minimum package at least 25 MB . 2 . What does the legacy support look like for Windows respectively Mac . What OS versions does it support for offline executables using web view for running HTML content .. . Answer : Tidekit offers options to build and package apps that affect the size of the runtime . First TideKit will bundle only what it needs to keep the size of the runtime as small as possible . Builds allow you to optimize based on the requirements of your application the platforms you wish to support or to prioritize for things such as App Store compliance . Besides your code and our runtime the resources you include contribute to the total size . 1 . Packaging can involve bundling the runtime in the app or packaging the app with an installer that will only download a runtime when is not available on the host . Our runtimes are dynamic . The lightest scenario is network packaging with an installer that is auto-generated for you . Hello World can be bytes + the installer size . So perhaps 1 - 2 MB . In this scenario the host is checked for a runtime . If one is found it will be checked for requirements of the app . If it has what it needs there is nothing more . If the runtime on the host needs something it does not have it will fetch it during the install . If there is no runtime it is fetched during the install . Bundle installs include the runtime within the app and will make for larger apps . That size will depend on what you are using . Application bundles could be as low as 15MB range for size . We ll be able to provide more specifics as we reach our release . 2 .

And was there question non-programming like this : 1 https : stackoverflow.com questions 27800197 is-tidekit-still-in-progress 2 https : stackoverflow.com questions 26094684 tidekit-expected-release . Because I writed here . Comment : TideKit does not exist any more . See this answer http : stackoverflow.com a 28204167 3737186", "Question : I want to query with tideSDK a MS-SQL database . How can I realize this in tideSDK My approach was to extend PHP with PDO SQLSRV . But I do not come on . .. . Answer : I understand what you want however there was no native support for MSSQL in TideSDK . Our recent effort TideKit has native support for MSSQL along with other SQL and no SQL databases including Mongo and CouchDB . TideKit is releasing soon . You can find out more at http : tidekit.com or following on twitter at https : twitter.com tidekit .", "Question : I am interested in creating a desktop application using HTML5+webkit and I d like to be able to build a stand-alone executables for various target platforms like a .exe file for Windows and a .dmg image for Mac OS . I have played around with node-webkit https : github.com shama nodewebkit which seems nice except for the packaging distribution portion . I also stumbled on TideSDK http : www.tidesdk.org but that project seems to be inactive . For example the latest release I saw was a beta from November of 2012 . Yet it seems the core developers have switched to developing TideKit https : www.tidekit.com instead . Does anyone here know if TideKit is intended as a replacement for TideSDK Is TideSDK going away etc . Comment : fyi anyone passing by : TideKit is defunct don t bother . .. . Answer : If you look at this blog post they talk about how unsustainable the economical situation is .. . .. . http : www.tidesdk.org blog 2013 04 11 tidesdk-in-numbers .. . .. . and I can t find the tweet that was stating the reasons behind the transition from one project to another . But I guess that the blogpost speaks for itself . Anyway I m delivering a project written in node-webkit because I starded on Tide but for the obvious reasons I had to switch and I m using grunt for packaging and in the end is not that bad . Comment : OK that s basically the conclusion to which I came . I was just looking for something more authoritative .", "Question : I am using TideSDK Developer to create a new desktop app . I m not sure of the differences between TideSDK Developer and TiDev Community 1.3.03 I develop with php language . But I can t use Ti in my project . .. . Answer : TideSDK Developer was stripped down from TiDev Community 1.3 . TiDev community is not compatible with TideSDK and you cannot use it with code using the Ti namespace . Your only choice is to use TideSDK Developer . You must change the namespace on any API reference in a project created using the older TiDev Community to Ti for TideSDK Developer to build the project . Keep in mind TideKit is releasing soon with a new CLI app and will provide platform builds . You can follow recent developments at http : www.tidekit.com . The video of what is coming is here : http : youtu.be aE7gN-d0GhU . This will give you modern tools to use where the experience of creating and your projects is much better ." ] }

Comment : Here is an example C program that is drawing a create which is a textured cube using Cogl : github.com spatulasnout cogl blob master examples crate.c https : github.com spatulasnout cogl blob master examples crate.c .. . Answer : There are no CoglRenderer or CoglContext classes in the current vapi file for cogl-1.0 . I don t think you can even initialize Cogl without these which I can oddly only find in the documentation for cogl-2.0 . https : developer.gnome.org cogl-2.0-experimental stable .. . .. . Since there doesn t seem to be any Vala example at all and not many C examples it s difficult to ask your question . You should probably ask the Cogl mailing-list . Edit : Since your question was about Clutter + Cogl there is indeed a Vala example here : https : wiki.gnome.org Projects Vala ClutterSamples .. . .. . Edit2 : There is a Hello World tutorial using cogl-2.0 here : http : www.cogl3d.org hello.html .. . .. . As you can see Cogl is much more low-level when you use it standalone without Clutter you have to do a lot of setup code youreself create drawing context create a framebufer create your drawing primitives create a drawing pipeline draw your primitives etc . . I don t know how Clutter works internally but I think it does a lot of that work for you . In any case it can t hurt if you learn some OpenGL first since Cogl is a wrapper around OpenGL . Edit3 : This blog post shows how to integrate Cogle into Clutter : http : radialmind.blogspot.de 2012 02 cogl-or-opengl-for-3d-clutter-scenes.html .. . .. . So this is how you jump out of the clutter loop : Define a custom actor . I did one in C another example uses the C++ version . See also here . Define some properties that modify how things are rendered and some other general behavior . Override the paint loop . Save the matrices define your own matrices call your custom drawing code in 3D has to be cogl and then put the matrices back as you found them . Comment : I guess in cogl-1.0 there must be some clutter function that initializes it . Comment : So does this mean that i can t use cogl directly in vala so i will have to use C instead Comment : You may have to write some C stubs or import some missing functions using a vapi file . Maybe I have overlooked something in the clutter binding though . Comment : It is also possible that clutter already initializes Cogl so you don t have to do anything to initialize Cogl . Comment : I just found an so question about clutter and Cogl : stackoverflow.com questions 16170085 http : stackoverflow.com questions 16170085 filling-a-custom-shaped-clutter-actor-with-a-cairo-drawn-canvas", "Question : I m a little confused about the relationship of the libraries listed above here are what I think : .. . .. . 1 . Cario is a 2D graphic library and GTK+ uses it to render widgets . Cario is low-level . 2 . Cogl is a 3D graphic library based on OpenGL or a fork I don t know and Clutter is a 3D GUI toolkit based on Cogl . If this is correct will Clutter replace GTK+ someday And.. . If you think there is a better place to ask this question or some books I should read first please tell me I m self-learning programming for interest . .. . Answer : yes Cairo is a high quality 2D drawing API and GTK+ uses Cairo to draw itself . Cogl is a GPU programming library that internally can use GL or GLES to access the graphics pipeline though in theory it could as easily use DirectX on supported platforms . Clutter uses Cogl for rendering but it can also use Cairo for 2D elements . Clutter will not replace GTK+ : GTK+ is a very complex library that provides system integration complex widgets and other utility API that Clutter has no interest in providing . the future is going to be a bit more gray than a black-and-white replacement . Cairo can use Cogl to draw Cogl will program the GPU pipeline but Cairo will generate the geometry to be submitted so you can have high quality 2D results . Cairo already can use GL directly but Cogl has a better state tracking already . Clutter can use GDK the GTK+ windowing system API to talk to the windowing system surfaces and get input events . in the future it s entirely possible that GTK+ will use Clutter internally as the base for its widgets - though that s still a work in progress . in short a diagram could be : Comment : To bring it home a little if you are an app developer you might use gtk to create the window menus toolbars etc and use clutter to draw any app content that is drawing area like and doesn t fit into the widget-based app metaphor . Within clutter you may dig down to Cairo for specific drawing tasks .", "Question : My environment is Fedora 21 i play around with hello tutorial from http : www.cogl3d.org hello.html it shows : .. . .. .

I ve decided to switch to Clutter with Cogl for the drawing but Cogl seems to be somewhat limited for 2D . So far I m already missing being able set the dash pattern for a line as well as the line width . I ve read two things that you can use raw GL calls within Cogl and that you can use a ClutterCairoTexture . Unfortunately I can t find any documentation on using GL calls inside of cogl begin gl cogl end gl and ClutterCairoTexture has apparently been deprecated . It would be incredibly useful to know either how to use a Cairo context with a Clutter texture or how 2D drawing is accomplished now in Cogl . I can t really understand why you wouldn t be given the ability to change the line width in Cogl but it doesn t seem to be in any of the documentation that I ve read . The dash pattern I can deal with if I had to but it would definitely be better if I could either continue to use Cairo in an Actor Texture or if Cogl had some way to do it . Thanks . .. . Answer : Turns out the answer is to continue using Cairo but create a ClutterCanvas and add it to whatever ClutterActor you re drawing to . After that you just need to connect a function to the draw signal which gives the CairoContext as a parameter .", "Question : I m going to build clutter on mingw environment but when I try to build Cogl there are some compling errors unknow type : GLchar GLintptr GLsizeiptr .

Cario is a 2D graphic library and GTK+ uses it to render widgets . Cario is low-level . 2 .

If you think there is a better place to ask this question or some books I should read first please tell me I m self-learning programming for interest . .. . Answer : I think the relationship between libraries are interdependent that is a library can not stand on its own . It needs to depend on others in order to run .", "Question : null .. . Answer : I m working on a program that uses Clutter 1.10 and COGL to render elements to the display . I ve created a set of ClutterTextures that I am rendering video to and I d like the video textures to have reflections . The standard way to implement this seems to be a callback every time the texture is painted with code similar to : .. . .. . This is then hooked to the paint signal on the ClutterTexture . There s a similar bit of code here http : mathijs.dumon.alwaysdata.net entry clutterreflectioneffect-class that does something similar . Google cache since the page has been down today http : webcache.googleusercontent.com search q cache 3ahttp : mathijs.dumon.alwaysdata.net entry clutterreflectioneffect-class .. . .. . The problem that I m having is that the reflection effect is causing a performance hit - 5 7 fps is being lost when I enable it . Part of the problem is likely the low-power hardware I m using a Raspberry Pi . I ve managed to do something similar to what this code does by setting up a clone of the texture and making it somewhat transparent . This causes no performance hit whatsoever . However unlike the paint callback method the reflection has hard edges and doesn t fade out . I d like to get a better looking reflection effect without the performance hit . I m wondering if there s some way to get a similar effect that doesn t require so much work per paint.. . There are a bunch of other Clutter and COGL methods that manipulate materials shaders and so forth but I have little to no OpenGL expertise so I don t have any idea if I could get something along those lines to do what I want or even how to find examples of something similar I could work off of . Is it possible to get a better looking high performance reflection effect via Clutter COGL Comment : you may not get any better performance on a Raspberry Pi the GL capabilities of that platform are pretty low .

That s OK but what functionality And what other functions from the library are similarly affected I have had a google but not turned up any info on this . I have seen it used in opengl-es apps also which IIRC only has the core opengl functionality . Can anyone here shine any light on whether all functions are suspect or if it is just load ogl texture .

I use the following code : .. . .. . However my terrain looks steppy because the height is expressed with 8 bits only . How can I load 16-bit height map with SOIL Or should I use another image library for this task Comment : SOIL should be able to load 16-bit BMP images at least from what I can garner from it s source code . Would it be possible to supply both the image you are trying to load and the one being output by SOIL Comment : This really is not a good idea . GL LUMINANCE is not supported in modern OpenGL implementations and your format data types are all wrong . If you want a single-component 16-bit image format use GL R16 for the internal format GL RED for the pixel transfer format and GL UNSIGNED SHORT for the pixel transfer type . Frankly I don t see what SOIL has to do with anything in this question . Comment : @Andon M . Coleman as you pointed out I had incorrect values for the internal and pixel transfer formats . However this does not solve the problem because SOIL returns the contents of image as an array of unsigned bytes not 16-bit values . The question is - how to load data in an unsigned short array Comment : If you want to load an array of 16-bit data don t even bother with SOIL . There are only a handful of HDR image-formats you would be better off avoiding an image file altogether and just store your data in a raw binary format . You can always layer it on top of something like zlib to improve storage requirements . Comment : @Andon M . Coleman OK that is probably the best idea so I am going to do so . .. .

I ve been using the SOIL library http : www.lonesock.net soil.html to make the task of loading textures simpler and I am fairly sure that this is where the problem lies . I understand the most obvious answer is to not use SOIL and to learn raw OGL first before I try using extensions and I do intend to do this . However I would still like this problem solving for peace of mind . My personal assumption is I have probably enabled some sort of shading somewhere or there is some quirk of OGL or SOIL that forces the shade of the texture to change however I am not experienced enough to solve this .

Answer : This is how you do it . Note that as others have mentioned in the comments a context needs to be maintained current for every thread that uses GL . What this means is practically there cannot be a GL API call made in multiple threads without making one thread the owner of the GL context . Hence if the intention is to separate the Image loading overhead it is recommended to load the image file into a buffer using a library in a separate thread then use that buffer to glTexImage2D in the main thread .

I have a program that does deferred shading across two separate hosts and one of its unoptimized data paths involves dumping the G-Buffer to disk and fetching it as a network share . If that can sustain 60+ FPS at high resolutions this is going to be an increasingly frequent mistake . This technically does not even stall the render pipeline the old duplicate data is not interrupted so most drivers will make a separate copy on each frame and it s mostly down to disk throughput possible image decode .

Ex : Create a simple gradient of red in memory then load that as a texture . Then once you have that working try loading the texture with SDL . Comment : Thanks for the advice . The SDL which uses libpng worked with GL RGBA16 . The only error i get now is that the SDL GetError specifies that i use sRGB and it is not the correct color format .

I want to be able to thread it so that it can load during a menu screen or a splash-screen or something of the sort . So my question is if SOIL is not thread safe then would a decent solution be to run a thread to run the menu splash-screen whatever in order to allow textures to load in the main thread Comment : It is not so much whether SOIL is thread safe as it is whether you have a valid OpenGL context in your worker thread . Window systems only allow an OpenGL render context to be bound to a single thread at any given moment this is worked around by either relinquishing a single context and passing it between threads synch . overhead makes this a bad idea or using multiple contexts that share resources . In any event if you try to use the results of an OpenGL command in a thread that has no OpenGL context-bound this sort of thing tends to happen . Comment : My bet is that you or someone else didn t compile SOIL correctly to use in a multi-threaded program . .. . Answer : OpenGL isTHREAD BOUND Which means you can make calls on your GL context from a single thread at a time . Thanks to datenwolf for correction If the above mentioned method uses GL methods which I suppose it does then it won t work unless you do it in separate GL context.If you want to go multi -threaded way you can create shared context - each in separate thread.Then you render in the main thread while loading the textures in another one.I am not sure how much it is performance wise but you can give it a try anyway . Comment : OpenGL is not really single-threaded it s thread bound . I.e . at any moment a given OpenGL context can be used from only one thread . It s however possible to migrate a context between threads .

Answer : The issue is likely given the vintage 2008 of the SOIL library as documented at this link http : www.lonesock.net soil.html that whatever version of Visual Studio was used to build the prebuilt SOIL library predates Visual Studio 2012 and there is thus a binary incompatibility between your program and the SOIL.lib . One thing you could try is to change the platform toolset in your Visual Studio 2012 build to be a previous version that is compatible with the prebuilt SOIL library . You may have to do some searching of the SOIL documentation to figure out which version that is and some searching of MSDN to find the right platform toolset if you don t have it already .

In my experience with writing portable Win32 Linux server code 15+ years I personally find boost ACE unnecessarily bloated and introduces maintenance hazards otherwise known as dll hell for the little advantage they give . ACE also seems to be horribly outdated it is a c++ library written by c programmers in the 90-s and it really shows in my opinion .

Answer : The ACE socket libraries are solid . If you are trying to port a standard implementation of sockets you can t go wrong . The ACE code sticks to a rigid development paradigm . The higher level contructs are a little confusing to use . The rigid paradigm causes some anomolies with exception-handling . There are or used to be situations where string value pairs being passed into an exception with one of the pair being null causes an exception throw in the exception that will boggle you .

Getting up to speed with it can be somewhat daunting but there is a lot of literature on it and commercial support available . It s somewhat heavy though so for smaller-scale apps it may be a bit of an overkill .

Answer : Many POCO users report using it alongside Boost so it is obvious that there are incentives for people in both projects . Boost is a collection of high-quality libraries . But it is not a framework . As for ACE I have used it in the past and did not like the design . Additionally its support for ancient non-compliant compilers has shaped the code base in an ugly way .

Answer : I recently got a new job and work on a project that uses ACE and TAO . Well what I can tell is that ACE and TAO work and fully accomplish their tasks . But the overall organisation and design of the libraries are quite daunting.. . .. . .. . For example the main part of ACE consists of hundreds of classes starting with ACE . It seems like they ve ignored namespaces for decades . Additionally many of ACE s class names don t provide useful information either . Or can you guess what classes like ACE Dev Poll Reactor Notify or ACE Proactor Handle Timeout Upcall can be used for Additonally the documentation of ACE is really lacking so unless you want to learn ACE the hard way it is really hard without any good documentation. .

Comment : ACE is the ultimate network-programming swiss army knife for C++ programming but last I checked it was also a huge monster dependency in itself . .. . Answer : I have used ACE for a very high performance data-acquisition application with real-time constraints . A single thread handles I O from over thirty TCP IC socket connections and a serial-port . The code runs on both 32 and 64 bit Linux . A few of the many ACE classes I have used are the ACE Reactor ACE Time Value ACE Svc Handler ACE Message Queue ACE Connector . ACE was a key factor to the success of our project . It does take a significant effort to understand how to use the ACE classes . I have all the books written about ACE . Whenever I have had to extend the functionality our system it typically takes some time to study what to do and then the amount of code required is very small . I have found ACE to very reliable .

Answer : Boost is great I ve only heard good things about POCO but never used but I don t like ACE and would avoid it in future . Although you will find fans of ACE you will also find many detractors which you don t tend to get with boost or poco IME to me that sends a clear signal that ACE is not the best tool although it does what it says on the tin . Comment : ACE has been around for a very long time and has had to support many legacy platforms over the years . This is one of the reasons why it isn t as modern Boost for example . A great deal of extremely useful research and literature came out of ACE see Doug Schmidt s CV that others have been able to leverage and build on . Naturally others will learn from mistakes made in older libraries and improve on them . Others will also come up with completely new ways of doing similar things as well . Don t be too hard on ACE . I m also a big fan of Boost . Admittedly I ve never used POCO . Comment : ACE was started at a time when compilers were very incompatible no standard existed yet and templates were a complete nightmare 1996 1997 and there were a hundred Unix-like platforms . I evaluated ACE+TAO for a project - we eventually settled on OmniORB TAO was so immature it broke with every new release . ACE on the other hand was a rock . It shows it age in terms of library setup but it s solid and it has a large following . I did fear a bit of the benevolent dictator however - if Schmidt ever went boots up ACE might be trouble .

Comment : ACE is the ultimate network-programming swiss army knife for C++ programming but last I checked it was also a huge monster dependency in itself . .. . Answer : I ve used all three so here s my 0.02 . I really want to vote for Doug Schmidt and respect all the work he s done but to be honest I find ACE mildly buggy and hard to use . I think that library needs a reboot . It s hard to say this but I d shy away from ACE for now unless there is a compelling reason to use TAO or you need a single code base to run C++ on both Unix variants and Windows . TAO is fabulous for a number of difficult problems but the learning curve is intense and there s a reason CORBA has a number of critics . I guess just do your homework before making a decision to use either . If you are coding in C++ boost is in my mind a no-brainer . I use a number of the low-level libraries and find them essential . A quick grep of my code reveals shared-ptr program options regex bind serialization foreach property tree filesystem tokenizer various iterator extensions alogrithm and mem fn . These are mostly low-level functionality that really ought to be in the compiler . Some boost libraries are very generic it can be work to get them to do what you want but it s worthwhile . Poco is a collection of utility classes that provide functionality for some very concrete common tasks . I find the libraries are well-written and intuitive . I don t have to spend much time studying documentation or writing silly test programs . I m currently using Logger XML Zip and Net SMTP . I started using Poco when libxml2 irritated me for the last time . There are other classes I could use but haven t tried e.g . Data : : MySQL I m happy with mysql++ and Net : : HTTP I m happy with libCURL . I ll try out the rest of Poco eventually but that s not a priority at this point .

I would like to know the good and bad of each . Comment : ACE is the ultimate network-programming swiss army knife for C++ programming but last I checked it was also a huge monster dependency in itself . .. . Answer : As rdbound said Boost has a near STL status . So if you don t need another library stick to Boost . However I use POCO http : pocoproject.org because it has some advantages for my situation . The good things about POCO IMO : .. . .. . Better thread library especially a Active Method implementation . I also like the fact that you can set the thread-priority . More comprehensive network library than boost : asio . However boost : : asio is also a very good library . Includes functionality that is not in Boost like XML and database interface to name a few . It is more integrated as one library than Boost . It has clean modern and understandable C++ code . I find it far easier to understand than most of the Boost libraries but I am not a template programming expert : . It can be used on a lot of platforms . Some disadvantages of POCO are : .. . .. . It has limited documentation . This somewhat offset by the fact that the source is easy to understand . It has a far smaller community and user base than say Boost . So if you put a question on Stack Overflow for example your chances of getting an answer are less than for Boost .. . .. . It remains to be seen how well it will be integrated with the new C++ standard . You know for sure that it will not be a problem for Boost . I never used ACE so I can t really comment on it . From what I ve heard people find POCO more modern and easier to use than ACE . Some answers to the comments by Rahul : .. . .. . 1 . I don t know about versatile and advanced . The POCO thread library provides some functionality that is not in Boost : ActiveMethod and Activity and ThreadPool . IMO POCO threads are also easier to use and understand but this is a subjective matter . 2 . POCO network library also provides support for higher level protocols like HTTP and SSL possibly also in boost : : asio but I am not sure . 3 . Fair enough . 4 . Integrated library has the advantage of having consistent coding documentation and general look-and-feel . 5 . Being cross-platform is an important feature of POCO this is not an advantage in relation to Boost . Again you should probably only consider POCO if it provides some functionality you need and that is not in Boost . Comment : From what little I have learned about POCO things dont seem to add up : 1 . boost-thread seems much more versatile and advanced . 2 . POCO is more versatile in what ways 3 . I am only interested in networking . XML and database do not concern me . 4 . Integrated as one library I am not sure if thats a good or bad thing 5 . Boost I believe and that goes for boost : : asio also is also quite crossplatform . Comment : @Rahul I tried to answer some of your points in the answer . Comment : I haven t looked at POCO recently but it when I did look at it a few years ago I was put off by the fact that components seemed to use a mixture of licenses . Some used the Boost license others were GPL . Some of the encryption stuff required a license for commercial use .

Comment : Same here. . the problem hasn t gone away after adding those attributes . Comment : Scratch that you have to do this to EVERY script that Ace requires not just ace.js .

Comment : What you mean by other things in AS stop working like datasources Are they already created datasources and i assume you are using AS 5.2.1 Comment : I m working with AS 5.0.0 as I told in my entrance I had some datasources created for a few dataservices that were working well when I overwrote the wso2carbon.jks with the one I had created and rebooted the server the created datasources disappeared and an error appeared when I tried to recreate them again I switch back the older wso2carbon.jks and everything work fine again but I can t consume the secured web service Comment : I guess those datasource resources stored at registry and those resources getting encrypted when storing . Have you tried to create new datasource or try the scenario in a fresh pack where keystore is changed to new one from the beginning . .. . Answer : When you add your own certificate you need to modify the WSO2 configuration-files to point to your certificate . Basically you need to modify repository conf carbon.xml and repository conf tomcat catalina-server.xml . In case of ESB you need to modify repository conf axis2 axis2.xml as well . The changes needed are described in this blog http : ajithvblogs.blogspot.com 2012 12 how-to-add-new-keystore-to-carbon-4 3.html . The error that you faced with data sources is because of the change of certificates . The reason is that WSO2 encrypts the datasource passwords using the current keystore certificate at the time of datasource creation . To fix the error you will need to remove your datasources and re-add them . No need to re-create your data-services though .", "Question : I am being confused by wso2 aplication server . When i access a non-exist page it will always redirect to carbon console I have studied the xml config files but find no luck . I just want to know how to make it just report 404 error when it does happen .. . Answer : I have found the answer the reason is the carbon app occupied the context root so all request to non exist context-roots will be received by carbon app .

Answer : Have you changed the host name in the carbon.xml of the AS 1st Case : In default wso2carbon.jks have its CN as localhost so you need to change the keystore if you are working with different host name or else you need to invoke hosted web service using localhost . 2nd Case : If you changed created and replaced the wso2carbon.jks of the AS with a appropriate CN you need to extract its public certificate and import it into cacerts and client-truststore.jks of all other carbon servers which contact with AS .

Implementing a similar thing in ArrayIterator would mean either creating a new object or looping through the keys unset ing all of them one by one then setting the elements from new array one-by-one . Next since the ArrayObject cannot be iterated when you use it in foreach it creates an ArrayIterator object internally same as arrays .

All though it comes with a lot of built-in utility functions but they are all procedural . Both the ArrayObject and the ArrayIterator allow us to make arrays first class citizens in an Object Oriented program OOP .

Comment : Also Stackoverflow is not your personal research assistant http : meta.stackexchange.com a 128553 164367 .. . Answer : ArrayObject and array are somewhat alike . Merely a collection of objects or native types . They have some different methods that you can call but it mostly boils down to the same thing . However an Iterator is something else completely . The iterator design pattern is a way to secure your array making it only readable . Lets take the next example : .. . .. . You have a class that has an array . You can add items to that array by using addSomethingToMyArray . Note however that we do something to item before we actually add it to the array . This could be anything but lets for a moment act like it is very important that this method is fired for EVERY item that we want to add to the array . The problem with this is that you pass the array by reference here . That means that classes that actually use returnMyArray get the real myArray object . That means that classes other than A can add things to that array and therefor also change the array inside A without having to use the addSOmethingToMyArray . But we needed to doSOmethingToItem remember This is an example of a class not in control of its own inner status . The solution to this is an iterator . Instead of passing the array we pass the array to a new object that can only READ things from the array . The most simple Iterator ever is something like this : .. . .. . .. . .. . As you can see i have no way of adding new items to the given array but i do have posibilities to read the array like this : .. . .. . Now there is again only one way to add items to myArray in A namely via the addSomethingToArray method . So that is what an Iterator is it is somewhat of a shell around arrays to provide something called encapsulation .", "Question : I am trying to clone an ArrayIterator object but it seems like the cloned one is still referencing to the original one . Anyone have explanation to this behavior Thank you in advance . .. . Answer : Though I am having difficulty locating documentation that explicitly says so internally ArrayIterator s private storage property wherein the array is held must be a reference to an array rather than the array itself directly stored within the object . The documentation on clone http : php.net manual en language.oop5.cloning.php says that .. . .. . PHP 5 will perform a shallow copy of all of the object s properties . Any properties that are references to other variables will remain references . So when you clone the ArrayIterator object the newly cloned object contains a reference to the same array as the original one . Here is an old bug report https : bugs.php.net bug.php id 36941 wherein this behavior is said to be the expected behavior . If you want to copy the current state of an ArrayIterator you might consider instead instantiating a new one using the array returned by getArrayCopy http : php.net manual en arrayiterator.getarraycopy.php .. . .. . The above is a simple operation though and only creates a new ArrayIterator with the currently stored array as the original . It does not maintain the current iteration state . To do that you would need to also call seek to advance the pointer to the desired position . Here is a thorough answer explaining how that could be done http : stackoverflow.com a 20069139 541091 . Comment : I was also looking for the same documentation but as it says Warning This function is currently not documented only its argument list is available . I was also thinking about the same reference issue as you explained the array is held must be a reference to an array rather than the array itself directly stored within the object . But after testing myself I see it s not referring some external array . But it stores the array inside which then it keeps as reference when cloning . I don t know actual reason for it but based on this scenario the sentence above is not 100 accurate . Comment : You can test it with this myArray array m list new ArrayIterator myArray Later you will see that the ArrayIterator doesn t impact the original myArray for it s future operations . Comment : I tested that as well - the reference is not to the original array variable passed to the iterator - it is an internal reference to an array otherwise inaccessible to PHP code copied from the array variable passed to the iterator . If it were a reference to the original variable that would make the iterator s state potentially inconsistent . Comment : Yeah that s correct Comment : I hoped to be able to inspect it with a ReflectionProperty but on an internal class it seems it isn t possible to retrieve private properties . In any case that bug report I linked does clearly state that this behavior is intended . If you clone an ArrayIterator you also clone its reference thus the described behavior below is correct .", "Question : I am trying to understand something about ArrayObject http : php.net manual en class.arrayobject.php and ArrayIterator http : php.net manual en class.arrayiterator.php classes .. . .. . ArrayObject : This class implements the IteratorAggregate http : php.net manual en class.iteratoraggregate.php and Traversable http : www.php.net manual en class.traversable.php interfaces . Since IteratorAggregate extends Traversable itself why does ArrayObject implement both when it can just implement IteratorAggregate ArrayIterator : As above this class implements both Iterator http : www.php.net manual en class.iterator.php and Traversable which Iterator extends . Why do these classes implement two interfaces when they could get away with implementing the one that extends Traversable Comment : I suspect those links are only there to make the manual clearer and more traversable ha - ironically in your case that seems to have had the total opposite effect . I think you are correct in that one would more correctly say that they implement the IteratorAggregate and Iterator interfaces respectively .

But when I leave the loop and dump the array from the iterator it s back to the original values . What s happening Comment : Looks like this is a bug you should file on bugs.php.net http : bugs.php.net .. . Answer : It seems that values in plain arrays aren t modifiable because they can t be passed by reference to the constructor of ArrayIterator RecursiveArrayIterator inherits its offset methods from this class see SPL Reference http : www.php.net helly php ext spl .

Is using this- getArrayCopy instead of ok Is there any better solution for doing that What about performance And how to change array of class dynamically for example using array-walk . Regards .. . Answer : Notice that the ArrayIterator class implements ArrayAccess . To modify the array simply treat this as an array : .. . .. . Unfortunately functions such as in array don t work on array-like objects you need an actual array . getArrayCopy will work but I would just use array this . EDIT : As salathe notes in a comment getArrayCopy is better because it always gets the internal array while array this will behave differently if you use the STD PROP LIST flag . Performance-wise making a copy of an array like that does cause a small slowdown . As a benchmark I tried getArrayCopy and array on an ArrayIterator of 1000000 items and both took about 0.11 seconds on my machine . The in array operation itself on the resulting array on the other hand took 0.011 seconds - about a tenth as long . I also tried this version of the in array function : .. . .. . That function runs in 0.07 seconds on my machine when searching for a value that doesn t exist which is the worst-case scenario for this algorithm . The performance problems are too small to matter in most cases . If your situation is extreme enough that 100 nanoseconds or so per array element actually make a difference then I would suggest putting the values you want to search for in the array keys and using offsetExists instead .

Any help would be greatly appreciated Thanks Comment : Late to the show but I was also looking around and built a small Node.js script to do this : github.com aramk mongodb-git-backup https : github.com aramk mongodb-git-backup .. . Answer : All you need is MMS Mongo monitoring service . It is a cloud based continuous backup service plus lot of automation like on-demand restore monitoring offered by MongoDB . With MMS every single time you make a commit the DB gets backed up incrementally . It also possible to easily deploy and monitor standalone replica-set or a sharded setup . MMS is better compared to mongodump as it tends to do an incremental backup vs whole database backup.Writing a script which does mongodump on every commit will work but you will have to delete the old backup file every time you want to backup for a new commit . MMS cuts down on this devops overhead by manging all of this boiler-plate effort writing scripts like mentioned that goes into DBA s role .

The automation agent is using more CPU than my entire cluster combined mongod s + mongos 6 processes total . That s what concerns me . Comment : Could you submit a ticket to the MMSSUPPORT https : jira.mongodb.org browse MMSSUPPORT project in MongoDB JIRA Be sure to include your MMS group name .", "Question : I am looking into setting up MMS Automation agent but found out that there is no download for windows .

You are able to simply install MongoDb MMS Windows Agent according to this official documentation : .. . .. . http : mms.mongodb.com help-classic tutorial install-monitoring-agent-on-windows .. . .. . Update : After installing the agent according to the above instructions you need to submit a ticket in their support to enable monitoring for Windows . It can not be enabled automatically as it is not listed in their OS list yet . Comment : Thanks this was an awesome find . However I was able to setup and configure my MMS monitoring on Windows without opening a ticket . The API key is the same key that you would find in the Mac OS X tutorial . I was able to connect it to mongoDB by adding a connection in the deployment tab .", "Question : null .. . Answer : I am using MMS to monitor a 13 node MongoDB Cluster 3 Config Servers 4 MongoS 2 replica sets with 2 members + 1 arbiter each . MMS was working properly since its installation but now it is not monitoring the shards replica-sets properly . It is monitoring only 4 nodes 1 Primary 1 Secondary and 2 arbiters out of 6 nodes and auto-removing the other replica-set primary + secondary every time I am adding them manually . Also for the replica-set it is monitoring it is taking the primary secondary and arbiter as independent nodes even though it is showing correct TYPE for them in the monitoring window . When I checked Host Mapping it was surprised to see that it was showing the same alias name for both the Primary nodes and same for both the secondaries . I guess this is the reason it is not showing those 2 nodes in the monitoring window . I manually removed those entries of same alias names from the Host Mapping window but it is auto-updating it after few minutes . Why is it considering the two different nodes as same and taking the same alias name for them Is it a bug MMS is working well for Config-servers and MongoS nodes . My MMS group is MMS@Ork .. . .. . My Data nodes are as follows : .. . .. . Server1 - Primary of Replica-set1 + Secondary of Replica-set2 2 Nodes Server2 - Primary of Replica-set2 + Secondary of Replica-set1 2 Nodes Arbiters of both replica-sets are on separate machines . I have kept one port-number common for both the primaries and other port-number common for both the secondaries . Comment : Version of all the nodes in the cluster is 2.4.9 and that of MMS monitoring-agent is 2.3.1 Comment : This is a question about administrating MongoDB not about programming for it . This means the question is much more appropriate for dba.stackexchange.com https : dba.stackexchange.com . I nominated the question for migration . Comment : Thanks Philipp .", "Question : I would like to know if there is a way to get the hostname of the server which has the problem through MongoDB MMS . By default they give only following details . .. . Answer : Please find this link as well : http : www.litixsoft.de english mms .. . .. . Hope below will make sense to your question", "Question : I m relatively inexperienced with sysadmin work but I m trying to figure out how to connect MMS to my Meteor app to sync regular backups of our MongoDB instance . The app was deployed on Digital Ocean using MUP but MMS doesn t seem to want to connect to the Mongo Instance . I was wondering if there are any specific steps that need to be taken to make MMS work properly . It appears as though MMS requires standalone instances to be reconfigured to be replica instances but I m not quite sure how this works . I was wondering if anyone else has gone through this and could assist . Thanks .. . Answer : For MMS to be able to manage your servers remotely you need to install the MMS Automation Agent on each server that s running MongoDB and you need to have specific ports open so they can access the automation agent . Use the instructions for installing the agent on your specific operating-system https : docs.mms.mongodb.com tutorial nav install-automation-agent . Also use the MMS Automation Checklist https : docs.mms.mongodb.com core automation-checklist to make sure you have everything configured properly . Comment : Thanks Brian . I think there is an issue with the mongod instance being installed as a standalone instance vs as a part of a replica set . In addition MUP installs mongo so that it can only be accessed locally . Are you aware of this causing issues", "Question : null .. . Answer : Received a Host is down alert from Mongo DB cloud Manger MMS but Host is running fine .

Answer : I am attempting to setup the MongoDb Cloud Manager Automation Agent so that I can automatically update my MongoDb deployment though I am running into the following error : .. . .. . The user mms-automation does exist in the admin database and was granted the permissions required . I can connect to the database via mongo mongodb : mms-automation : password@myservername.c.my-google-cloud-project.internal : 27017 admin and execute use admin db.getUsers as well as use admin db.system.users.find . Note that when installing the MMS Automation Agent a requirement is that the result-of hostname -f executed on the MongoDb server must be a FQDN that is resolvable from all other servers . I assume this to be all other servers listed in the Cloud Manager running MongoDb deployments . In this case the result-of hostname -f is yservername.c.my-google-cloud-project.internal the internal hostname of my compute node .

Answer : Unlike OpenGL which availability in a compiler toolchain is mandated by the Windows ABI FreeGLUT is an optional 3rd party library that must be installed separately . Most simple course of action would be to simply drop FreeGLUT sources into a subdirectory of your project and just add it to your CMakeLists.txt FreeGLUT comes with a ready to use CMake configuration so that will just work .

I went and downloaded cygwin x including the x-org server and xinit but still that does not work . Comment : @ChrisProcak : Well the problem you re running into is that Cygwin tries to provide maximum compatibility with Linux . And in Linux you do graphics through an X server . But in Windows there is no X server unless you start the X server that comes with Cygwin but the OpenGL support of that is meager at best . Instead of Cygwin I strongly advise you to use MinGW to compile your project . The easiest way to install it is using the MSys2 installer msys2.github.io https : msys2.github.io to get a MSys2 environment and then install mingw inside it . That will give you native OpenGL support which you want .", "Question : Some context : I am going through a tutorial http : openglbook.com on using OpenGL .

At best on OS X with Mountain Lion you ll get a 3.2 core context which is similar enough to 3.3 - but unfortunately this is incompatible with GLUT - OS X includes the original GLUT unmodified due to licencing issues which requires many obsolete OpenGL functions that aren t available in 3.2 core contexts .

I ve also added opengl32.lib and freeglut.lib to the Additional Dependencies . Why is VS looking for freeglutd.lib It s definitely not listed in the Additional Dependencies . I can solve the compilation error by renaming libglut.lib to libglutd.lib and removing the former from the dependencies but I m just curious why it s behaving this way .

I tried both debug and release-mode . I also did as you suggested and created a new project but no luck . Comment : Hmm interesting . Btw I just so the end of your question - yes opengl is needed as a dependency because freeGLUT uses OpenGL but covers some of its complexity window creation input event-handling initialisation of OpenGL stuff etc . Can you post a screen shot of your project settings linking dependencies headers etc . . OpenGL does not require freeGLUT but I have the feeling that you are writing OpenGL code from somewhere where freeGLUT is used instead of pure OpenGL hence the dependency on freeGLUT . Comment : I just realised I wasn t applying the suggestion from the linked answer properly . I defined those macros after including GL glut.h which is pointless . I can now say the problem is with FREEGLUT LIB PRAGMAS being equal to 1 . More specifically if it is equal to 1 GL freeglut std.h will try to link libglutd.lib if NDEBUG is not defined . So it is meant for debug builds but Release mode doesn t define NDEBUG by default . PS upon inspection of the glut header file opengl32.lib is linked for you if FREEGLUT LIB PRAGMAS is 1 .

Have XQuartz setup . Tried with no luck to get version 3.2 .. . Answer : Freeglut is an extended implementation of the SGI GLUT Toolkit and with a few exceptions around obsolete hardware implements the same functions . Unfortunately this includes a number of features that would break in a strictly CORE FORWARD COMPATIBLE implementation . Typically if you request a context WITHOUT specifying a version or profile you will get the best that the combination of driver and GL toolkit can offer which is normally a compatibility profile rather than core profile . Note that the only thing you lose through using a compatibility profile is the supposed checking for deprecated functions . All new core function should work without issue . This problem with freeglut is not restricted to Apple it also manifests under Linux using some Gallium drivers . It is not clear that there is any short-term intent to rectify this so if you need to use CORE FORWARD COMPATIBLE you should probably switch to GLFW or SDL .", "Question : I am using the following configuration .. . .. .

I will first decide the which context to by checking the supporting version using glew and some other parameters . I know for glew to work it needs a opengl context .

Somethings are missing from the scene .. . .. . So is there some specific callback function I need to put this display command I dont think there is any destroy callback I can set . yes there is glutCloseFunc but I think that is meant to be called when window is being destroyed that is when glutDestroyWindow has been called on window .. . Answer : I think you can argue that this is a FreeGLUT bug either in the implementation or the documentation . It looks like glutDestroyWindow needs to be called from a GLUT callback to work properly . glutDestroyWindow mainly puts the window on a list to be destroyed https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg window.c L263 as well as clearing all callbacks https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg structure.c L177 except a destroy callback . This is probably why setting the display function didn t work for you - it was removed when you called glutDestroyWindow . Windows are actually destroyed-at the end of each main loop https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg main.c L466 . So on the first time through the loop your window still exists . The fact that it has no display callback makes GLUT unhappy https : github.com dcnieho FreeGLUT blob c59188a9a8d14efbeed7b0d6feacae7b04d7ad69 freeglut freeglut src fg main.c L410 . The best workaround is probably to arrange to call glutDestroyWindow only via one of the GLUT callbacks . I don t know if this will make the window briefly flash on the screen . My guess is it won t but it might depend on the platform . Comment : I have updated my questions . please see Comment : Weird . Try glutIdleFunc https : www.opengl.org resources libraries glut spec3 node63.html . Comment : My glutIdleFunc is same as my Display function Comment : Not sure what you mean by that .

However its usage is quite straight-forwadd as soon as one knows about how OpenGL s context versions work which was defined in the ARB create context https : www.opengl.org registry specs ARB wgl create context.txt familiy of extensions . The function will select which OpenGL version is requested when the context is actually created . Note that this does not require the implementation to return a context with exactly the version you are requesting but it should return one that is compatible to the requested version so that all features of that version are present . There are a few things which seem to be undocuemted about freeglut handling this . From looking into the code for the current stable version 2.8.1 one will see that freeglut implements the following logic : If the implementation cannot fullfill the version constraints but does support the ARB create context extension it will generate some error and no context will be created . However if a version is requested but the implementation does not even support the relevant extensions a legacy GL context is created effectively ignoring the version request completely . This seems a bit inconsistent to me . However as this stuff is not documented and not part of the GLUT spec it is unclear if the behavior will stay the same in the future or not . If you don t need some GLUT-specific features which are basically all relying on deprecated OpenGL anyway you ll might want to look at some more modern alternatives like GLFW http : www.glfw.org .

For a reason I don t get no binaries are distributed . Where can I download the .lib and the .dll files Comment : It s a lot easier for library developers to provide the sources and allow you to compile it than to provide precompiled binaries for every OS compiler in existence . That being said compiling it is fairly trivial . So perhaps tell us what it is you re using which compiler . OS is Windows it seems and where you re stuck . Comment : I m using Visual Studio 2012 and Windows . I tried compiling it but there were include errors it think because of the gl .. . . Also types like GLint are used which can t be found . Comment : Please update the question to include the exact version of FreeGLUT you re compiling and the exact errors you get .

Have XQuartz setup . Tried with no luck to get version 3.2 .. . Answer : In 10.8 and 10.7 GL 3.2 is available if you explicitly call for it when setting up the GL context . Apple calls this the Core Profile to distinguish from the Legacy Profile which is GL 2.1 . I ran into this issue with Wine on OSX it does not support OpenGL 3.2 . My understanding is that the X11 server either Apple X11 or XQuartz currently does not implement the 3.2 support nor is there a switch to flip somewhere to enable it . It could be for compatibility concerns since 3.2 profile will break some existing GL applications https : developer.apple.com library mac documentation graphicsimaging conceptual OpenGL-MacProgGuide UpdatinganApplicationtoSupportOpenGL3 UpdatinganApplicationtoSupportOpenGL3.html apple ref doc uid TP40001987-CH3-SW1 .. . .. .

Comment : I am sorry but don t see how this relates to my question . As I have said - OpenGL 3.2 DOES work with GLFW which runs on top of XQuartz on my system so it does definitely support 3.2 contexts . My only issue is that I would like to use freeglut purely because it s more convenient . But if that s not possible then I will develop using GLFW .

Answer : It was suggested http : lists.macosforge.org pipermail xquartz-dev 2009-April 002304.html on Xquartz s mail list that the freeglut demo is wrong to declare those PFN PROC twice . So by simply commenting out those double-definition from smooth opengl3.c the free glut would pass the compilation phase . However from my experience it would not run and give some error about the GLSL .

So far we ve managed to get the input from the 36 keyboards and recognized the 36 sound cards without getting a kernel panic which happened before updating the kernel . We know the 36 sound cards have been recognized because lsusb grep Audio -c outputs 36 . However aplay -l lists 32 playback devices in total including the internal sound card . Also alsamixer -c 32 says invalid card index : 32 works just from 0 through 31 32 in total too .

From the code and its comments I read two things : .. . .. . 1 . The variable cards limit is a module parameter . I assume that on your installation this parameter is set to 32 . If ALSA support is built into the kernel you can build a custom kernel where you changed this option . If ALSA support is not built-in but loaded as a module you can set this parameter during module load . For this you either change your system config man modprobe.d or unload the module then reload it with the option man modprobe . 2 . The limit is described to only limit the number of automatically loaded soundcards . To overcome this limit it may suffice to manually load the module responsible for your soundcards . There is no limit set in the kernel for manually added soundcards .

Am I better off using PulseAudio or JACK Can those be used to play the captured audio Comment : Also would the ALSA snd pcm mmap.. . functions improve latency .. . Answer : I believe you should at first ensure that you are running a Linux kernel which actually allows you to achieve low typical latency . There are several kernel compile-time configuration options which you might look into : .. . .. . CONFIG HZ 1000 .. . CONFIG IRQ FORCED THREADING .. . CONFIG PREEMPT .. . CONFIG PREEMPT RT FULL available only with RT patch .. . .. . Apart from that there are more things you can do in order to optimize your audio latency in Linux .

We re running Ubuntu Linux 12.04 with the 3.6.3-030603-generic kernel . So far we ve managed to get the input from the 36 keyboards and recognized the 36 sound cards without getting a kernel panic which happened before updating the kernel . We know the 36 sound cards have been recognized because lsusb grep Audio -c outputs 36 . However aplay -l lists 32 playback devices in total including the internal sound card . Also alsamixer -c 32 says invalid card index : 32 works just from 0 through 31 32 in total too . So my question is how can I access the other sound cards if they re not even listed with these commands I m writing an application in python and there are some libraries to choose from but I m afraid they ll also be limited to 32 devices in total because of this . Any guidance will be useful . Thanks . Comment : Are you afraid or have you tested it Comment : I tried pyaudio and get device count lists 32 in total including some aliases not sure if the right word such as default . So I can access even less devices . Comment : How did you connect all these devices to the PC Won t this be too much for the bus bandwidth Can you actually use the current 31 devices all at the same time Comment : For the application we re trying out they don t need to be all playing simultaneously but all of them have to play sound at some point . They re connected using 2 root hubs connected to another level of hubs with 3 sound cards and 3 keyboards each . We ve yet got to find out if it works this way or find another solution such as adding another root hub and redistributing them or adding a queue or something . I ll read about the bus bandwidth thanks .. . Answer : The sound card limit is defined as the symbol SNDRV CARDS in include sound core.h . When I increased this seven years ago I did not go beyond 32 because the card index is used as a bit index for the variable snd cards lock in sound core init.c and I did not want to change more than necessary . If you make snd cards lock a 64-bit variable change all accesses to use a 64-bit type and adjust any other side effect that I might have forgotten about you should be able to get the kernel to have more ALSA cards .

It worked just fine until about a month after I got it when I decided I should start adding audio to the game I m programming . That s when I realized that my audio wasn t working . I asked my dad for help . At first he refused saying that I would learn more by doing it myself . But eventually he agreed to help . He did a bunch of stuff in the terminal and he then opened a program called qjackctl . He started the JACK audio server waited a bit then stopped it . Music started playing the moment he stopped it . He didn t explain what he did and said he was just checking if it was even possible to get the audio working . It worked until I rebooted the computer . I then tried to replicate what he did and I opened qjackctl started it then stopped it . My audio started working again . I kept doing this for the next week or two and one day it stopped working . I have no idea why . All I did each of those days were just Python Pygame programming . I kept experimenting with qjackctl and the program output said something about killing pulseaudio can t remember exactly what it said . So I opened top type top in terminal killed pulseaudio started and stopped the program and my audio started working again . I kept doing that for about a week every time I rebooted then it magically stopped working again . Does anyone know how to fix this and preferably make it permanent I ve spent quite a while researching how to fix this but I haven t found anything so I decided to see if anybody else could figure it out . EDIT : I just looked in the KDE settings and I noticed that the only item in the multimedia audio section is Pulseaudio . Nothing else shows up not even alsa . I really need this information any help is greatly appreciated . .. . Answer : on debian gnu linux youve got a lot of different ways to produce audio output . The base system would probably be the alsa interface of the linux-kernel which can be accessed by an userland application directly or through a sound server which is also an userland application . The two sound server softwares i know are pulseaudio and jackd . Both are different implementations with different design concepts . jackd is meant to be more in the professional audio studio area while pulseaudio is meant to give a easy sound system for desktop systems . It is only possible to run one of those on top of one alsa device sound card . And if you would like to access your alsa device directly none of that should use it . So first of all i would check what interface pulseaudio jack alsa is supported by the application that you want to use to generate audio output . After that you should get sure that the appropriated components are running . For example you can install mplayer which is capable of using all of that methodes . There you can use the option -ao to select the interface you want . Here you see a sample . Your description sounds like if your application is using plain alsa only and is inhibited by a running pulseaudio instance . Even tho pulseaudio has got a simulated alsa through pulse interface but that is often not working correctly . So if that the case i would suggest to uninstall pulseaudio by running .. . .. . as root . You can find many information about alsa pulseaudio and jack using the Internet search-engine off your choice . The arch linux wiki has a lot of good hints for example : .. . .. . https : wiki.archlinux.org index.php PulseAudio .. . .. . https : wiki.archlinux.org index.php JACK Audio Connection Kit .. . .. . https : wiki.archlinux.org index.php Advanced Linux Sound Architecture .. . .. . except packaging it can be applied to debian to .. . .. . the rest is figuring it out by trail and error.. . .. . .. . i wish you much success Comment : Sorry I forgot to mention my computer at home has no internet access so I can t use anything that s not already on there . My parents don t trust me enough to have internet access but my dad did install almost the entire Debian archive hundreds of gigabytes so I probably do have mplayer already . I ll check when I get home I m in school right now .

So I m using Matlab on a Linux Gentoo machine . I got a few Asus Xonar STX soundcards and I m trying to use them as sensitive audio frequency analyzer using the PlayRec http : www.playrec.co.uk non blocking audio IO package . Now I know that Matlab will say if you try to use the audiorecorder function and specify 24 bits in linux it will tell you that 24bit is only supported in Windows . However the ALSA literature does not imply that this is a limitation of the operating-system or of ALSA itself and as a matter of fact Alsa seems to allow you to specify a 24 bit PCM device . And PlayRec uses PortAudio which then uses Alsa on Linux systems . Now this is all well and good and Playrec doesn t seem to have a means of specifying the bit depth just the sample rate . I have run many tests and know what the transfer-function of my soundcard is floating-point return-value to input Voltage conversion ratio and I know my peak voltage is 3V and my noise is around 100uV . This gives me 20 log10 3 100e-6 91dB . Which is closer to what I expect to see from 16 bits and not from 24 . My real question is this : Is there some way of verifying that I am in fact getting 24 bits in my captured signal And if I am not is there some inherent limitation of ALSA or Matlab which is restricting me to only 16-bit data from sound capture devices even when using 3rd party program to gather that data . .. . Answer : If you can store that signal as a wav file run a file command on the wav from the command-line in linux . Something like : .. . file x.wav will give you sampling rate and bits that the file was encoded at . The output is usually something like : 16-bit 16000Hz etc . Comment : Well I like how you are thinking the only problem is that by the time its read into Matlab the signal becomes 2 channels of single precision floating-point numbers . So writing it to a wav file using wavwrite or some other function seems like it will then simply convert the file to the bit depth and sampling rate you specify it at rather than retain the characteristics it had when it first came out of the A D . That is why I tied doing my own S N computation since the Xonar STX SHOULD have 118dB of dynamic range which they prove in the manual with audio precision and I m getting 91dB .", "Question : null .. .

Starting simple I glued together various samples from the ALSA project site and other online sources to do the simplest thing : read a WAV file and play it on the default sound device . I cannot get this simple C sample to work . I am using libsndfile to do all the WAV file reading header decoding . I verified that the samples I read into the buffer are correct verified first 400K samples of what the program reads in against the sndfile-to-text application that dumps the sample values to a text file . So I know my buffer contains the right data the problem must be in the way I pass it to the ALSA APIs . When run it produces sound only in the right channel and distorted muddy - barely recognizable . BTW the aplay application plays the same WAV file perfectly and reports the file is 16-bit signed LE 44100Hz stereo which matches what my application reports as well . Running this on a Raspberry Pi . I stripped the C program down to the minimum here to conserve space but I verified correct return codes from all API calls . Why does this simple ALSA application not produce the correct sound .. . Answer : You must check the return values of all snd functions that could fail . The S16 LE format has two bytes per sample but int has four . Use short instead and sf readf short .

My code just initializes PortAudio opens and starts a stream one channel paInt32 sample format defaultLowInputLatency defaultLowOutputLatency though I tried changing to paFloat32 or defaultHighInputLatency defaultHighOutputLatency which didn t improve anything . On each invocation of the callback it copies sizeof int32 t frameCount bytes via memcpy from the input to the output buffer then returns paContinue . It does nothing else in the callback . No memory allocation no system calls nothing it could block on . It just outputs what it has read . The code is very simple still I can t get it running . Replacing the memcpy with a loop copying frameCount elements of type int32 t over from the input to the output buffer didn t change anything . What I ve tried : .. . .. . The following scenarios were tried out with PortAudio . 1 . Input and output via USB audio interface callback mechanism on PortAudio ALSA backend . 2 .

Answer : When you write only a single block of samples the playback device will run out of samples just when you re about to write the next block . You should fill up the playback device s buffer with zero samples before you start the read-write loop . Comment : Thanks Are you sure this is how it works with PortAudio It s a realtime API . The callback gives you an input and an output buffer and a number of frames and as far as I understand expects you to read EXACTLY this number of frames from the one and write this number of frames to the other . I expected the API to call me on each block then output what I ve written into the output buffer just after I return . So call on each block and 1 block delay as the block I process is always output in the next iteration . This is also how it s done in examples . I don t think there s a buffer involved . Comment : In theory the realtime API should take care of that . Do PortAudio s example programs work Comment : Like I said I tried the paex read-write wire.c example since like my application it does both input and output but it uses blocking I O . It doesn t drop out like mine but it underruns all the time and output is grossly distorted . There s sample code in paex saw.c that outputs a sawtooth wave using callback mechanism but has no input and this works on the onboard sound but also outputs ALSA warnings about no channel map but causes lots of underruns and distortion on the USB interface . Note that the USB interface works fine with normal applications under ALSA . Comment : If PA does not work in the first place there s nothing your program can do . Comment : So the library itself is broken Ain t that unlikely given that it s pretty common What should I do Try yet another library I just came from plain ALSA where I had severe latency problems so people told me to use a callback-based API . Also ALSA contains bugs .

Also see Relation between period size of speaker and mic http : stackoverflow.com q 15835764 11654 and Recording from ALSA - understanding memory mapping http : stackoverflow.com q 14762103 11654 .", "Question : I used to work on Ubuntu 12.10 but then suddenly my speakers stopped working my headphones didn t used to work before and still they are not working i then upgraded to 13.04 in hope that it may solve my problem but it was not the case . I have read dozens of websites and suggestion and tried them out but none worked . As i open my sound configurations the only option available there is Play sound through Dummy output and i am unable to change that . Please help me out . P.S I have my ubuntu dual booted with windows-7 . And the speakers and headphones work fine on windows . .. . Answer : You should install alsa drivers from alsa launchpad. . be sure to install the latest version and that too of raring as you are using 13.04 . After install try rebooting the laptop . This will make the sound work .", "Question : I need to send audio from a radio to a secondary system using an embedded-linux system . The secondary system needs to set up a communication channel which takes a few seconds . So if I don t want to lose the beginning of the audio I need a way to record the sound and play it back with a custom delay a few seconds maximum . It should be possible to start arecord to record the audio in a file in a tmpfs filesystem and when a communication is incoming start aplay . But in this case the beginning is still lost because the signal to record is coming too late . Is there a program on Linux which is recording sound continuously in a ring buffer in RAM and able to playback with a custom delay on demand If not what is the best library to code such a program on an embedded system alsa or something else Comment : On Linux every audio library eventually ends up using ALSA . However you can use any other library if it s easier to use . Comment : Is this question off-topic since it asks for a tool or library Comment : Alsa has support for LADSPA plugins there should be one featuring a fixed delay . Comment : Is it appropriate to code up a script to do the buffer and pipe stuff together like in buffer-me 5s out Such a script would be fairly trivial to write if perhaps in a naive way . Of course it would be more efficient to do it in the existing sink or source . .. . Answer : If all you need is to have a buffer to keep sound output until it is ready to be consumed a variant of this should work : .. . .. . Start recording : .. . .. . Start playing when yours output device is ready : .. . .. . Tweak the output buffer size to fit your needs . EDIT given that playing can start anytime : .. . .. . If you need to continuously record and start playing anytime you could split the output into smaller files using the split command and delete the old files in a helper process . Something like : .. . .. . And to play : .. . .. . This solution is quite dirty but might work preferably on tmpfs as you have already mentioned .. . Comment : I would like to record all the time with a circular-buffer can be only 240K for 60s of 8000Hz 8bit audio and then when it should play it would use dd to play from the correct position in the buffer . In your case stdbuf will block when the buffer is full . Comment : Then I misunderstood your question . I will edit with another idea which is not a perfect solution but might be a working solution .. .", "Question : How do you listen to changes in volume on the Master channel on the default sound card I d like to be notified through dbus or a callback or something that the volume has changed . I have tried looking and the ALSA and PulseAudio APIs and they only seem to allow you to set and get the volume but not listen for changes in the volume . Any programming language is fine . .. . Answer : This is possible with the ALSA API . When you have a control device call snd ctl subscribe events to enable events . Then use snd ctl read to read events to wait for them use blocking mode or poll . If the event is of type SND CTL EVENT ELEM and if its event bit mask contains SND CTL EVENT MASK VALUE that element s value has changed . See the implementation of amixer monitor http : git.alsa-project.org p alsa-utils.git a blob f alsactl monitor.c hb HEAD for an example . Comment : Thank you very much Comment : If anyone is wondering this turned into a node.js plugin here https : github.com illegalprime alsa-monitor-node ." ] }

Comment : What OS is on your Laptop Comment : windows-7 ultimate .. . Answer : Even though this question was posted long time ago I didn t find 100 correct answer from previous replies . Most of replies are useful but here is one final step for debugging apps on Sony Xperia devices . My Sony Xperia T has not been visible in Eclipse even though I installed PC Companion and in mobile phone I set developers options debugging mode Xperia has very strange option : .. . Settings Xperia USB Connectivity USB connection mode .. . and select Mass storage mode MSC . Note that the USB cable must be unplugged to change this option . By default Media transfer mode MTP was selected . If MTP is selected even little bug is shown in notification bar debugging is not possible Comment : Great thanks this also worked on my Sony Xperia Tablet Z -- I would never have found that option otherwise : - Comment : I have a Sony Xperia M and this is been the solution to my problem . With no PC Companion and MSC usb connection mode the android device manage on my Eclipse got to recognize my phone . Thanks . Comment : Aside from the usual stuff : installing google usb drivers PC companion enabling debugging allowing apps from unknown sources etc . Enabling MASS STORAGE worked The Sad part was that I couldn t listen to the MP3s on my phone while it was hooked to eclipse . Fortunately whe you activate MASS Storage for the first time the phone asks you to include your computer in the Trusted Devices List . Once you do so you can then put it back to Media Transfer Mode and enjoy Eclipse connection while listening to MP3s at the same time Happy Coding .", "Question : null .. . Answer : I have a locked Xperia Z3 and I wish to take advantage of Sony s AOSP for Xperia Devices http : developer.sonymobile.com knowledge-base open-source open-devices program . Reading through the disclaimer attached to the Sony Device Unlock procedure it states that unlocking the device will void the warranty and more problematically erase the DRM keys which will render various hardware features useless . However reading through the AOSP build procedures http : developer.sonymobile.com knowledge-base open-source open-devices aosp-build-instructions how-to-build-aosp-lollipop-for-unlocked-xperia-devices documentation you can build Android from the AOSP tree and add to the repo Sony s blobs presumably with Sony-specific functionality . developer.sonymobile.com downloads tool software-binaries-for-aosp-lollipop-android-5-1 .. . .. . If there are any Sony people reading this my question is do we get back the DRM wiped out by the unlocking procedure if we build from the official Sony AOSP + official Sony in-tree binaries Thank you for your time . Comment : I don t think you do . Also you should post this on the Sony forums because you are more likely to get an answer there especially if you ask one of the few people who actually do build AOSP for xperia devices . I myself wanted to use Sony devices because of the AOSP program but because of reasons just like yours I scrapped the idea and just use a Nexus 5 .

Answer : At my software developing company we are developing multiples Android apps that use the camera to take pictures . We found an unsolvable problem in two Sony devices : The onActivityResult method is not called by the Camera Intent so there is no event triggered on the app to handle the image file and continue the app process . We don t know why and neither how to handle the problem . This is the way we use to call the camera from a Fragment : .. . .. . The questions are : .. . .. . 1 . Have you experienced this problem with some devices Specifically the Sony Xperia Devices The Sony devices that present this problem were Sony Xperia E4 and Sony C2104 . 2 . How do we handle the problem before launching the camera How can we tell the onActivityResult method was not called back Comment : You don t have to do any thing in onActivityRes since you already had defile the file for uri of image if the file-uri was not define by you then the onActivityResult will give you the file-uri . As you already defined the file-uri before starting the intent you will get a null value in onActivityResult One more thing is that if you are starting the intent from the fragment then you have to define the onActivityResult on the parent Activity . Right now i will suggest you to right your code of onActivityResult inside onResume of the fragment or define onActivityResult in your parent activity . Comment : I understand your approach but i don t think is the best solution to handle the picture in the onResume despite you don t need to use the onActivityResult params . This method was created for that and try to fool the fragment s lifecycle is never a good idea . Most of the smartphones tested works succesfully but those Sony Xperia are the only exception . Comment : The best approach is to define the onActivityResult in your parent Activity as well from there only you will get the Intent value for your fragment for onActivityResult you just understand the first part but didn t understand my second part . hope now you got it Comment : It works thanks man Comment : Your Welcome :", "Question : I am totally new at testing apps on devices especially the Sony Xperia .

It is a very special problem but I try to fix it in System Rules . .. . Answer : Scanner is buffered so each constructed instance is consuming more of the text from the mocked System.in than just what s needed for nextDouble . The next Scanner tries to read what s left from the same underlying stream but the input has already been consumed so nextDouble throws NoSuchElementException . You could try to more accurately mock System.in by returning fewer bytes but not indicating the end of the stream until the next call to System.out is detected or change approach and use Runtime.exec to spawn a new JVM and capture all output from that process .", "Question : I m tasked with setting up some JUnit tests for a utility app that is required to System.exit 1 under various circumstances and System Rules http : stefanbirkner.github.io system-rules is great for testing that . The app can also run in GUI mode and it pops a small JFrame . When it s running in the context of a JUnit test with the ExpectedSystemExit rule applied as the JFrame is constructed something surreptitiously exits the jvm . Turn off the ExpectedSystemExit rule and the test runs as it should popping the JFrame just fine it s just I can no longer test for jvm exit s . .. . .. . A guess would be that the SecurityManager System Rules 1.9.0 puts in-place is disallowing some permission s . I m still in the process of collecting more debug info . Until then is there a known solution this issue Comment : Are you invoking setDefaultCloseOperation JFrame.EXIT ON CLOSE It calls SecurityManager.checkExit which System Rules interprets as exit . Comment : @Banthar Indeed further debugging shows setDefaultCloseOperation JFrame.EXIT ON CLOSE is triggering the exit . So now what .. . Answer : setDefaultCloseOperation calls SecurityManager.checkExit to verify exit can be called . System Rules is based on SecurityManager and interprets that as call to exit . This will both cause your test to fail and make it impossible to construct your awt windows . You have to create your windows and call setDefaultCloseOperation before ExpectedSystemExit registers SecurityManager . For example in @BeforeClass method : Comment : That would require altering the app to put in a hook after the JFrame is constructed . I was hoping for an in situ solution .

Any ideas Comment : Please show us the complete command-line that you use to run pg-upgrade . You should not run that as Administrator a regular user is enough but you have to make sure that the access rights on both data directories are setup correctly Comment : @a horse with no name - I updated the question to show the full command-line .

Do you know where does pg-upgrade try to save pg-upgrade internal.log to Comment : No idea . I just did an upgrade from 9.4 to 9.5 with a regular user account and everything worked fine so I guess the file is stored in some temp directory of the current user . I had to quote the path to the .exe and I used the wrong way of quoting the path which then resulted in very strange errors . That s why I asked for the full command .

I have looked but not found anyway to pass a currency symbol as an argument . .. . Answer : The only documented way https : github.com jquery-globalize currency-formatting to modify the currency symbol in Globalize is to change the numberFormat.currency.symbol property of a given culture in this case the fr-FR culture . This will kind of do what you want but it s not a very elegant solution and you would need to manually build a table of correct symbols for each locale and write another method to swap them out . n.b . It is possible to pass a third argument to Globalize.format with a different locale identifier but this just formats the number using that locale s cultural settings . Looking at the culture definition syntax https : github.com jquery-globalize defining-culture-information there is simply no provision for displaying different currencies using a given locale . If you were to look elsewhere the dojo currency http : dojotoolkit.org api dojo currency module in the Dojo Toolkit does do exactly what you need using data from the Unicode Common Locale Data Repository http : en.wikipedia.org wiki CLDR to determine how to represent various currencies in different locales . So you can set your locale to fr write currency.format 3899.888 currency : USD and it will output the currency in USD in the correct format for the French locale .

Answer : The Globalize plugin provides parseInt and parseFloat methods that you can use : Comment : Yes I tried that but it converts the value back to javascript language and it doesn t support culture anymore .

When user focuses on that input i want to allow him to edit the value but remove the currency symbol --- the new value should be 100000 25 which respects the culture s currency format .

Answer : The difference is that an adaptive-layout has set layouts for certain screen sizes which means that the content is set to fixed sizes in each of those layouts and it just toggles between them . A fully responsive layout means that everything is scaled using percentages and relative units-of-measurement so that it constantly responds to ANY screen-size not just a certain set of sizes .

Comment : So basically responsive : liquid : : adaptive : fixed-width Comment : Responsive and liquid are essentially the same with the difference there being that responsive also uses the adaptive layouts at different breakpoints whereas liquid only scales . And fixed-width static is essentially the same as adaptive except that it only has 1 layout and 1 breakpoint while an adaptive-layout can have multiple . Responsive and static are basically at the ends of the spectrum with liquid and adaptive sitting somewhere in between .

Responsive web design as coined by Ethan Marcotte means fluid grids fluid images media media-queries . Adaptive web design as I use it is about creating interfaces that adapt to the user s capabilities in terms of both form and function . To me adaptive web design is just another term for progressive-enhancement of which responsive web design can an often should be an integral part but is a more holistic approach to web design in that it also takes into account varying levels of markup CSS JavaScript and assistive technology support . .. . For the record I do think it s important to draw a distinction between adaptive web design and adaptive layouts because adaptive layouts implies only the use of media-queries which may not be done in a progressively enhanced way . Adaptive layouts achieved in a mobile-first manner however are very likely progressive-enhancement and thereby a means of adaptive web design .", "Question : I ve read up a lot on adaptive-design . All the sources I could find at some point mention server-side approach or at least talk about how it makes faster loading times because you only serve what the client needs . In contrast with responsive-design you deliver out one content that adapts on client-side by media-queries for example . Fluid grids and layouts come to my mind . However I thought of a very basic naive and from my understanding pretty boneheaded approach that I just could not find a pattern for . Probably because it s so dull . My idea was basicly to craft a separate view for each device like you d normally do with adaptive-design but put them into divs and just display the one that matches the device dimensions . This of course delievers depending on the views about n -times as much data as server-side adaptive-design would with n being the number of different views .

EDIT : Thanks to the comments so far I want to emphasize : I totally agree on this being pretty much the definition of an anti-pattern . I hope my question makes that clear I don t consider this a practical thing . However I am interested in what this is called if it is called anything at all or if it is still adaptive responsive by definition . If not why Comment : No this pattern is called bad design for so many reasons some of which you ve already mentioned . It would probably take me an hour to write down all the reasons that come to mind when considering this . Comment : This would be a worse version of responsive-design . Comment : HTML is about semantic . CSS is about styling . Your semantic has the same information 3 times . .. . Answer : To me this seems more like an anti-pattern or the responsive-design pattern . The point of adaptive-design is to limit the amount of work the browser does and also to reduce the amount of traffic to and from the device . Think about how this would work on a device with poor bandwidth such as a mobile phone with a patchy signal . It makes more sense from a usability perspective for the server to decide what to send to the device based on the user-agent or other criteria . Comment : I am quite surprised you mention responsive in this case because what I did there is from my understanding anything but not responsive . related SO question http : stackoverflow.com questions 14831530 responsive-design-vs-adaptive-design Comment : It is only responsive in the broadest sense of the term because the device is in control of the layout . Essentially it is receiving the whole content and then hiding the bits it decides it doesn t want to see in other words responding to the display size .

Answer : Adaptive AWD : Not necessarily set on a fluid grid targets specific device resolutions 320 768 1024 et.al . can have set widths fixed or relative widths controlled by media-queries . Responsive RWD : Built on a fluid grid will-change with the browser no matter what the screen-resolution content can break apart and realign if need be .

Is it right Comment : Adaptive relies on Client or server-side code so if you want to care about it you could make that happen via Javascript etc . One usecase to keep in mind is using both . Create one responsive CSS for mobile one for PCs . Then use some Adaptive Techniques to filter out the clients device load in the appropriate responsive styles . In this scenario you get the best of both worlds . You could stay responsive across mobile-devices however you won t end up with a web view if someone is using a larger resolution mobile device and also have the option to keep a fixed or fluid design on the web .

Answer : I m redesigning a survey answering application and I want it to work on desktop tablet and smartphone . The desktop and tablet can use more or less the same interface but the phone is another issue . The large-screen app interface is more or less a table with a group of questions in the first column and the answers in the next columns . Questions can have anything from 1 bool to 9 choices . But this design is not easily transferable to a smaller screen . So my thought was to show single questions when the screen width goes below a certain threshold . All questions are pre-loaded and all answers are pushed to server on click . Yes JS is a requirement to answer . I m using CSS to transition between pages groups of questions on the large-screen app . On the small-screen I want to do the same thing only this time between single questions instead of groups of questions . See my exquisite sketch : .. . .. . enter image description here http : i.stack.imgur.com VKzTB.png .. . .. . Can I do this with responsive adaptive-design at all Or should I just load two different views on the different screen sizes Comment : this is definitely an adaptive-design as you will most probably produce different HTML based on the device . You could do it server-side or client-side .", "Question : What is the preferred way to handle adaptive it s not about responsive layout in AngularJS What I need to do is to have a different layout with different shared components shared directives and controllers for desktop and mobile . I was thinking about using ui-router here is what I have now : .. . .. . index.html main file : .. . .. . desktop.html wrapper for desktop content : .. . .. . mobile.html wrapper for mobile content : .. . .. . user.html shared content : .. . .. . app.js .. . .. .

Add a class to in index.html based on mobile desktop choice .. . 2 . Dynamically load mobile.css or desktop.css .. . .. . Best Regards .. . Answer : I recently ran into same issues that s why i landed here looking for some answers . According to my findings looks like i have two different options : .. . .. . 1 . Use your approach .. . .. . Facts .. . .. . Two partial different layouts because header and footer and some other body tags are still shared . Otherwise you will have to apply data-ui-view on html .. . This can be achieved only if you use ui-router this isn t working with angular default router .. . You will load all routes and configs both from desktop and mobile because you have a shared config file . This means that somehow you need to load all js files even if user is visiting only mobile version . Otherwise you will have to create a new config file for mobile version and use that one for mobile layout or dynamic exclude some route based on detected device . You will be able to switch from mobile to desktop within your Single Page Application without any reload . Not sure if this is an advantage or not . Good parts : .. . .. . You are not going to apply any server logic and your are not going to make a separation of main index.html file served from server . This means that the entire logic lies on the client-side . Bad Parts : .. . .. . You complicate the logic because you need to make a clear separation between devices and avoid loading unused js files if possible . If you are doing this basically you are doing another SPA because desktop version won t be available within your SPA . 2 . Share the same app but from server based on domain you can serve different html file . For example : yoursite.com will serve index.html which will eventually load desktop version and m.yourside.com will serve mobile.html which will eventually load mobile version . Facts : .. . .. . This is more like a hard separation and implies server logic to make a separation .. . When switching from mobile and desktop a reload will take place . Now you can t use the same config or other changes from app.js that refers to your desktop version so it might need to change some files to not refer anymore to libraries that are used for desktop .. . This approach looks more like a new angularJs app within same project folder structure application folder with same name maybe and lots of shared components and services but less dependencies and cleaner . To me this sounds more like a logic separation consider that you do not need to server all those js files on your mobile version maybe you won t use all the features of desktop version to mobile version . The only difference i see here at presentation level different routing maybe config file controllers and views . Still same models and share services and big componentes . In order to make a decision you need to think on both situations each with good and bad parts . Right now i don t know yet which decision to make i will investigate maybe a day or two . Good day and good luck . Andrei", "Question : I have a page on which i m worinking on an adaptive mobile design . Now I have the main navighation figured out but I have a second navigation that looks like : .. . .. . it is currently vertically displayed and I need it to change to horizontal orientation when my page s with is below 900px . http : www.quaaoutlodge.com content lodge - just shrink it s width to see what I mn talking about . Thank you Comment : here s a pen for you to try out demonstrating the inline and float media query-based answers . I used 400px as the break point codepen.io henry pen gbRXRg editors 110 http : codepen.io henry pen gbRXRg editors 110 .. . Answer : What s proposed below is the mobile-first approach . Basically you first style the elements the way they would look on smallest screens and then progressively adjust styles as screen width grows as in below example . For having elements be inline you can use display : inline-block but there can be undesired small spaces in-between so I ve used display : block combined with float : left - same effect without those spaces . EDIT : In your particular example the container secondnav has a limitied width so the above code won t work until you increase it s width too . EDIT 2 : Your menu items will still go to multiple lines as their width is set to 301 I think . Try to set it to auto or something less like 100px . Also you ll need to apply a background-color to the container secondnav I guess but these are styling considerations out of the scope of this question .", "Question : At some point I know I need to bite the bullet and do some serious reading on responsive and adaptive-design but I was hoping there was a really simple way to address this issue . I have the following web page shown here in my desktop browser . enter image description here http : i.stack.imgur.com qrPiL.jpg .. . .. .

The banner would never be bigger than the pixel width of the image on my desktop but would take up the entire width of my small cell phone . Is there any simplified approach to this Comment : have you heard of media-queries https : developer.mozilla.org en-US docs Web CSS Media Queries Using media-queries Comment : Make the image the dimensions you want it to be on mobile then use media-queries to restrict the width on desktop . Comment : @cocoa : Yes I have heard of media-queries and I get the basic idea . But I m new to them and was hoping someone could point me in the right direction to a really simple approach to do this on a very simple site . I guess I could make the width of stuff 100 when the device is small and say 60 when it s larger . Not sure yet if that s the simplest way . .. . Answer : You can use media-queries to handle style changes based on the viewport . For instance you can do something like : .. . .. . JS Fiddle Example http : jsfiddle.net kxgxkc8d 1 Comment : Thanks for the head start . Going to play with this a little . Comment : Just added a fiddle for the example .", "Question : I m not familiar with responsive websites and would like to start creating a website taking all the screens into account . Obviously media-queries is the way to go but they only concern CSS . In my current project I would like to organise the page differently according to the width of the page being completely device agnostic . The thing is on small widths I would like the HTML layout to change completely so I will have to make the HTML responsive as well as it should change according to the website width . How can I achieve that Is there any js library jQuery if possible but not mandatory that will serve another html page according to the width of the page The whole website should be build this way so the script should be more than a gadget it should be rock solid enough to allow the whole website to rely on it . And of course it should work on any device or screen or browser . Some would say that I m looking for adaptive techniques more than responsive ones but I believe it s a mix between those two as the elements will still be responsive in general but between some critical breakpoints it will indeed adapt and change the html . I read a lot about different techniques but I can t find something that suits my needs . Any lead would be appreciated . Thank you for your help . Comment : This is possible with both CSS Media Queries and with JavaScript - but probably not very practical . Try looking at things like the Twitter Bootstrap and Zurb Foundation both of which offer complete CSS frameworks for design development Comment : Try to understand what is CSS mediaquery You will get an idea of responsive website .. . Answer : What you are describing is adaptive delivery . What you want to to is detect the user-agent string using a server-side language and then conditionally render your templates according to whether the device is a phone tablet or desktop . Realistically you ll share a lot of code between the screens but you might have a different navigation layout or opt to not show more rich features on the smaller screens . This approach not only saves a bunch of hide show code but saves a lot of overhead on smaller screens where you would otherwise be loading stuff that would be hidden the entire time anyway . Comment : This is exactly what I want but being device agnostic as I don t want to specify any device anywhere . But I m still looking at something that does that without finding it yet . If I m not wrong the user-agent will segregate the browser or the device not the width and this is what I need . I found response.js but it doesn t switch the whole html tag-it just allows to change some div tags and src s . Comment : That s a tough one . If you wanna get really intense with it you can set up client-side views using something like Backbone or Angular and then use window resize events to trigger alternate content loads .", "Question : Would you explain difference between RWD Responsive Web Design and AWD Adaptive Web Design in a simple way Thank you .

Answer : I have the standard responsive image serving problem but with some complex twists . I expect I ll need to build my own solution to the below but it s a few months down the line so I thought I d bring this by the community now for help with my approach and getting started . I also think the solution I m looking for would have pretty wide appeal so this could be valuable to the community as a whole . The problem : .. . .. . We d like to provide users with images embedded videos etc anything that takes a lot of time bandwidth to load and takes less when lower res but change the loaded dimensions depending on the size the element is actually allocated on the page . This is basic responsive image serving applied to a few other types of assets though since we provide lower-bandwidth file versions to mobile-devices I think this also falls under adaptive-design . But don t worry about other types of content for now let s focus on images . We need to determine the appropriate max-width for a each specific asset placement for each screen width breakpoint without providing this info as configuration . I m creating a platform that will serve pages relying on HTML templates from many different parties . Images can be served from anywhere on the page and pages can use any styling system they want so we have no idea what the appropriate size for an image is just by looking at screen width . We need to actually evaluate the max width of the placement at each supported sizing breakpoint . Sure this could be done manually in advance given a design template but let s assume that s too much work for these 3rd parties . For example in Twitter Bootstrap 3 an image contained in a col-md-8 should be at most 720px width when browser width is 768 but if it was in a col-sm-8 it should be smaller than 470px . And if we re using a different framework altogether these would clearly be different too . I need solution that can take into account everything the CSS is doing automatically because I have no idea what the CSS will do . We can t do any processing during the image request . We rely on a CDN Cloudfront . They are not going to implement our custom code on each of their edge locations and I don t want a visitor in New Delhi or Berlin to have to send yet another request halfway around the globe for every sized asset before they know what the final url is . So that rules out solutions like this controller-based solution http : stackoverflow.com questions 14285473 adaptive-images-for-ruby-based-servers and the PHP adaptive-images script http : www.webdesignerdepot.com 2012 07 adaptive-images-solving-the-responsive-image-problem . We need this to be fast . There s a good amount of wiggle-room on the server-side since caching is so easy and flexible with Rails 3 4 . But we probably can t use jQuery.width on every element for performance reasons http : stackoverflow.com questions 12414150 jquery-width-method-performance . After all the entire reason we re serving responsive images is to decrease perceived page load-time . But we do have access to jQuery in general and we could probably load up Modernizr all the time if we needed to currently only included for low IE with conditional HTML . We don t trust User-Agent headers enough to base our browser width on them . I love the idea behind mobvious 1 https : github.com jistr mobvious 2 https : github.com jistr mobvious-rails and its friend responsive-images https : github.com johnkoht responsive-images but there are SO many versions of browsers on SO many different devices out there . How complex would it be to build a truly reliable system to determine browser width on this as opposed to directly calculating it using JS Clients without javascript and thus crawlers will need access to an image . Easiest solution here seems to be to include a noscript ... . noscript with the canonical largest version of the image inside . The solution It seems like the only way to do this is to : .. . .. . Have the server pass all the available sizes then calculate the width of each element on the client-side using jQuery in some performance-efficient way maybe using .css width or some sort of specialized script . So server would create : .. . .. . span data-respv-img-id picture of unicorns span noscript data-respv-img-id picture of unicorns data-img-720- url cdn.example.com assets picture of unicorns 720x480 data-img-320-url cdn.example.com assets picture of unicorns 320x260 data-img-120-url cdn.example.com assets picture of unicorns 120x80 img src cdn.example.com assets picture of unicorns 720x480 alt Magical unicorns noscript .. . .. . And if we re on a small screen and only the 120 fits the JS would turn this into : .. . .. . span data-respv-img-id picture of unicorns img src cdn.example.com assets picture of unicorns 120x80 alt Magical unicorns span .. . .. . OR have the server do some sort of pre-processing so it knows exactly what size image fits each placement on each browser width and delivers : .. . .. . span data-respv-img-id picture of unicorns span noscript data-respv-img-id picture of unicorns data-img-1200- url cdn.example.com assets picture of unicorns 720x480 data-img-1024-url cdn.example.com assets picture of unicorns 320x260 data-img-768-url cdn.example.com assets picture of unicorns 120x80 img src cdn.example.com assets picture of unicorns 720x480 alt Magical unicorns noscript .. . .. . And we end up with the same thing as the other approach . But this time jQuery s job was much easier as we passed all the sizing work off to the server . But this requires loading up a full browser stack on the server-side to generate each request . That s ok with caching but sure does bring a lot of complexity along . Note that both of these solutions would allow for scroll-based image loading which is another aspect I ll need to implement but not something we need to discuss now . Long story short : Which approach would you recommend Can you think of a better way", "Question : I hope the title isn t too confusing . I am using Adaptive Images to detect a visitor s screen-size and automatically create cache and deliver device break-point appropriate re-scaled versions of the web page s embedded HTML images . Now.. . some people want to save images on their mobiles smartphones but using Adaptive Images to serve up a smaller sized image to save bandwidth download time gives them the smaller scaled image - rather than a nice sized or the original image . Does anyone have any ideas on the following 1 . Serving up scaled images .. . 2 . Having the original available if people want to save them .. . Answer : From the Adaptive Images website : .. . .. . It creates and manages its own resized images using your existing images as the source and it will adapt to the same resolution brackets your site does with the CSS3 @media queries used in your Responsive Design . Your images are still the source it s only adapting them for viewing . Try downloading an image and viewing the properties .

If you shrink the screen and try downloading the image you will see the original properties while scaling appropriately . @media query :", "Question : Sorry for being long and thank you very much for your usual time and guidance . I have a div of unknown dimensions in fact its width and height are set using percentages so the final values in pixels depend on the window innerWidth an innerHeight properties . I need to create an ajax pagination inside that div . In other words I have two child div s figure below . The second one is for pagination links . The first one is responsible of holding items aligned horizontally and vertically . It will be automatically of unknown width . As a result the number of items inside depend on its final width and height because all items have a fixed known width and hieght Let s say 80 pixels width and 50 pixels height . I hope the following figure is illustrating my issue in the best manner : enter image description here http : i.stack.imgur.com fhAe9.png .. . .. . The goal is to find a good approach to find the values of X and Y . X number of items per row .. . Y the number of items per column .. . .. . These two values will help finding the number of items per page to be used server-side for pagination . Pagination links will be created by dividing the total number of pages by this value . Note : Everything is done with ajax . What I am planning to do : .. . .. . create a javascript function calculate viewport to be the first thing to execute before any other thing parsed exectued . create a javascript function that calculates X and Y values based on values returned by calculate viewport . use the X and Y for an ajax call that request a certain page . script type text javascript .. . .. . function calculate viewport .. . var width and height object .. . calcluate width and height using of current window.innerWidth and window.innerHeight .. . put values in an object width and height object .. . return width and height object .. . .. . function calculate XandY width and height object .. . var XandY object .. . calcluate X and Y values by perfoming necessary division operations .. . return XandY object .. . .. . var XandY calculate XandY viewport script .. . .. .

What do you think about this approach Are there any other better ways to achieve this goal Is it acceptable to create a script-tag before the html tag just to make early window size calculation N.B : For the server-side part I manage to paginate results via some functions offered by the ORM library I am using . I use a server-side template-engine that renders a page of items as HTML . I am ready to provide any code upon request for this part . Thanks .. . Answer : You ll never get the layout math right on your own . My recommendation is to lay out all of the items before hand flex box is ideal here get the count and then fill them in using ajax . Here s a quick demo http : codepen.io harangue pen VeJowz I whipped up . The actual JS is pretty simple using jQuery . The important line is the one containing .position . That ll get the location of each of the items top edge add the height to find their bottom edge and check if it s past the bounds of the item container . After this you can just use the count to query the necessary items from the server . I d also recommend using visbility : hidden on all of the items so the user doesn t see them before they re ready . Comment : Thank you for your time . If I understand you well you are suggesting a maximum intial number of items and setting visibility to hidden using the js you provided then using the count for the next pages to request only the necessary number of items in each page . right A note about flexbox it is not supported in IE8 and 9 and has only partial support for 10 and 11 which is a hurdle for me . display : table + table-layout : fixed has better browser support for info Comment : @whitelettersinblankpapers Yep That would be my approach anyway . The problem is interesting to me though because if a user resized their window the layout would break pretty quickly- I d usually chose a fixed-item layout in your situation . You can use flebox in ie8 and 9 you ll just have to make use of a polyfill https : github.com 10up flexibility Comment : I will be using your answer with flexbox thanks to my fascination after reading a guide about it of course I will be using the polyfill .

Now I want the column of tableview should be auto resize their width when user resize or maximize window by dragging application from corner or by clicking green button on top left . Any help will be appreciated . .. . Answer : Make sure your table view itself resizes when the window resizes by setting up constraints or setting its autoresizing mask . Then set the table s overall column autoresizing style . In a storyboard or XIB you do this by selecting the table view not the scroll view that contains it and then setting the Column Sizing popup in the Attributes inspector .

If you want all of the columns to expand or contract during a resize set it to NSTableViewUniformColumnAutoresizingStyle . Then set up each column s autoresizing behavior if necessary . If you are setting up your table in a XIB or storyboard you can select the column and then set its resizing behavior under the Attributes inspector .

I am not sure if you have the same problem but if you are using NSTableCellView under NSTableColumn then you need to set constraints for NSTableCellView . Highlight NSTableCellView and click on Resolve Auto-layout issue and click on Add missing constraints in the container . This will fix the issue if its same as mine . .. . Answer : The reason for this problem is due to constraints . If you are using NSTableCellView under NSTableColumn then you need to set constraints for NSTableCellView . Highlight NSTableCellView and click on Resolve Auto-layout issue and click on Add missing constraints in the container . This will fix the issue .

Please explain what you are actually planning to do with ADS . Comment : I m planning to use ADS . However there are open questions that are undocumented or have never been asked . Comment : Which features are undocumented .. . Answer : Many of your questions are covered here : http : flexhex.com docs articles alternate-streams.phtml .. . .. . 1 . Enumeration : Use NtQueryInformationFile see link . Beginning with Windows Vista you can also enumerate streams on the commandline using dir r . 2 . Checksums : As you usually open only the unnamed data-stream when you access a file by name only the contents of this stream are used when calculating checksums . 3 . Copying to NTFS : Windows Explorer and the copy commandline utility copy all streams . 4 . Copying to other FS : The alternate data streams are lost . 5 . Nested streams : No a file simply consists of a list of streams they cannot be nested . 6 . Attributes : Some attributes are file-based some encrypted compressed sparse are stream-based . 7 . LoadLibrary seems to work on alternate data streams . 8 . ShellExecute on an ADS failed with ERROR FILE NOT FOUND 2 on my computer . 9 .

Answer : From the top of my head : NTFS datastreams http : en.wikipedia.org wiki NTFS Alternate data streams .28ADS.29 were introduced in Windows NT 4.0 and have been around in all descendants excluding the win-95 descendants : 98 Me . In XP Vista and Win 7 they re still around . As long as Windows versions support NTFS they will support file streams . They will support NTFS for a long time to come . The error you have is described on the page you show in your question . The type command doesn t understand streams . Use : .. . .. . .. . .. . Working with streams .. . .. . Microsoft only has a handful commands that work with streams in fact only work with streams and thus only commands can be used that can work with these redirect operators . I wrote a couple of blog posts on alternate datastreams http : www.undermyhat.org blog tag alternate-data-streams on how you can still manipulate streams with only these commands . Streams will only work with programs that are designed to work with them simply because they need to be treated specially compare junction points also a feature of NTFS but the driver hides the details and programs do not need to do anything special : they just consider the junction point a real file . When you try to open a file stream using start filename : streamname and a program says something like illegal filename or file-not-found and you are positive that the stream name is correct then it s likely that the program does not support streams . I noticed that Notepad Wordpad and Word Excel work correctly with streams though Word and Excel consider the files dangerous .

Comment : Nothing is preventing you from using NTFS on linux see this question http : unix.stackexchange.com questions 14297 can-nix-handle-ntfs-ads-data-streams .. . Answer : There are file systems on both Windows and Linux and other OSes that support extended attributes EAs . The Windows support was added for OS 2 compat and does not have any documented interface except for a hacky method through the backup API that s what Cygwin does . EAs are designed to store small values only . On Windows each EA has an ASCII name whereas almost all other names are Unicode and the combined size of all EAs on a file can t be larger than 64k . EAs are not files : you can t open a file handle to an EA and read it like a normal file . Alternate data streams are a separate feature provided by NTFS which allows you to provide alternate subfiles inside of a file . Every file has a default unnamed data-stream that is automatically opened unless you specify an alternate one . You can open a handle to an ADS and read even execute it like a normal file with a single Unicode filename . An ADS can be as large as any disk file . There is no exact analog to ADSes on Linux that I know of but you may be able to use EAs on the Linux port instead if the data values are small . Comment : the default data-stream is named DATA Comment : @DanD . DATA not DATA .", "Question : According to MSDN each alternate-data-stream may be stored at an encrypted form NTFS encrypted state . The only API function I ve find for setting Encryption state is EncryptFile which states to encrypt all data streams of a file . So is there a way of not encrypting all data streams under XP .. . Answer : That MSDN article wherever you found it is wrong . NTFS encryption i.e . EFS itself stores the encryption keys in an alternate-data-stream EFS . There is only one EFS stream per file which would make it impossible for other alternate data streams to also be encrypted unless they also used the same symmetric key which would go against every design principle of EFS that uses different keys for every file . Please show the reference to that MSDN article .

I see that the MFT record has info regarding standard info file names data and few other attributes . I tried parsing the MFT record to get all the details that it contains . I am able to get filename data including data for alternate streams for all files but I was not able to obtain the filenames for the named alternate data streams . For the purpose of testing I created a file with two named alternate streams containing data . When I parsed the MFT record corresponding to the file I was not able to identify the alternate stream names . Does that mean the alternate stream names are not stored in the MFT Then how does some utilities such as stream.exe identify the alternate stream names .. . Answer : If you re parsing the attributes yourself you can find the offset to the name of the attributes in their common header . There is a WORD value in the header at offset 0x0A of the attribute if I m not mistaken I found it here ftp : ftp.kolibrios.org users Asper docs NTFS ntfsdoc.html concept attribute header . The offset points to the name of the attribute . The attribute header size + the length of the attribute name + the length of the data data run if not resident actual data otherwise should match the attribute length stored in the common header field offset 0x04 . If you re using the Windows API you can use the FindFirstStreamW https : msdn.microsoft.com en-us library windows desktop aa364424 28v vs.85 29.aspx function on a file to get it s streams .

Comment : @owlstead Yes they are unique and there should be no case of reusing the same IV unless the random nonce is reused by chance . Also the key is never reused so every new nonce comes with a new random key . .. . Answer : The definition of the counter is loosely specified in NIST recommendation sp800-38a Appendix B http : csrc.nist.gov publications nistpubs 800-38a sp800-38a.pdf . Note that NIST only specifies how to use CTR mode with regards to security it does not define one standard algorithm for the counter . To answer your question directly whatever you do you should expect the counter to be incremented by one each time . The counter should represent a 128 bit big endian integer according to the NIST specifications . It may be that only the least significant rightmost bits are incremented but that will usually not make a difference unless you pass the 2 32 - 1 or 2 64 - 1 value . For the sake of compatibility you could decide to use the first leftmost 12 bytes as random nonce and leave the latter ones to zero then let the implementation of the CTR do the increments . In that case you simply use a 96 bit 12 byte random at the start in that case there is no need for a packet counter . You are however limited to 2 32 16 bytes of plaintext until the counter uses up all the available bits . It is implementation specific if the counter returns to zero or if the nonce itself is included in the counter so you may want to limit yourself to messages of 68 719 476 736 68 GB yes that s base 10 Giga means 1 000 000 000 . because of the birthday problem you ve got a 2 48 chance 48 96 2 of creating a collision for the nonce required for each message not each block so you should limit the amount of messages .. . if some attacker tricks you into decrypting 2 32 packets for the same nonce you run out of counter . In case this is still incompatible test then use the initial 8 bytes as nonce . Unfortunately that does mean that you need to limit the number of messages because of the birthday problem . Comment : Note that reading the spec you can be reasonably sure that NIST only uses Big Endian mode so it s not so surprising that Apple only opted for that one in the end . Remarks like that in a crypto library do make me shudder though it seems to be an indication that the implementer did not read the specifications or did not understand them . In that case they should not be allowed to create a crypto library . Comment : Thanks for the info . I will read up on it and see if I can get CommonCrypto to work like it is supposed to or otherwise file a bug with Apple . Comment : The use-case here is an encrypted UDP stream with the IV and key being sent once via an encrypted TCP side channel . I need the packet counter to construct the IV since packets may be lost . Comment : I don t agree with the statement that with an 8 byte random part you ve got a chance of 2 32 to have a collision in the nonces . To be more correct on average it will take 2 32 messages before you see a repeated keystream . However you will want to stop using the key way before that . For CCM which uses CTR RFC5084 CMS recommends 12 bytes for the nonce . Other sources are in the same ballpark . 8 bytes is not secure as a general recommendation . Comment : Changed my recommendation according to the remark of @SquareRootOfTwentyThree Although this has a slightly higher chance of incompatibilities compared to an 8 byte nonce I think the increase of security is worth it in this case . If an 8 byte nonce is required by the library make sure you limit the number of messages encrypted with the key .", "Question : I understand that in AES Counter mode I need to use a 128 bit nonce . The na ve way to do that would be to use a random 128 bit nonce but I m not sure the algorithm will be able to increment the counter correctly if it s passed as all random bits . I thought the correct way to do it is to use a 96 bit nonce and also a 32-bit counter starting at 0 for example : .. . .. . Is this the correct way to do it with the CryptoJS library https : code.google.com p crypto-js Or what is the correct way .. . Answer : I m going to answer my own question as I went digging into the library code to see what it really does . Summary : .. . .. . The answer is you can use either of two methods and it will work as expected : .. . .. . 1 Pass in a random nonce of 96 bits in length and the library itself will add the 32-bit counter automatically and increment it with every keystream block generated . E.g . 2 Pass in a random nonce of 96 bits in length and explicitly specify the 32-bit counter as well if you want to . You can even specify a counter like 00000009 if you want to start encrypting decrypting from the 9th block . Below is an example starting from counter 0 : .. . .. . Explanation : .. . .. . Using the code in the question with 32-bit counter of 00000000 the relevant code is in this file mode-ctr.js https : crypto-js.googlecode.com svn tags 3.1.2 src mode-ctr.js : .. . .. . When running this code in a browser JS debugger using a breakpoint it converts the nonceAndCounter into a WordArray consisting of 32-bit elements : .. . .. . 587320654 -142251766 455884203 0 .. . .. . This is used to encrypt a block . To encrypt the next block it runs this line : .. . .. . counter blockSize - 1 counter blockSize - 1 + 1 0 .. . .. . Which evaluates to take the counter 3 element i.e . the integer 0 and increments it to : .. . .. . 587320654 -142251766 455884203 1 .. . .. . With subsequent blocks and nonces I can see.. . .. . .. . 587320654 -142251766 455884203 2 .. . .. . 587320654 -142251766 455884203 3 .. . .. . 587320654 -142251766 455884203 4 .. . .. . And so on . So it appears to be working correctly this way . Contrast this with how it works if you pass a 128 bit random nonce e.g . var nonceAndCounter CryptoJS.enc.Hex.parse 2301cd4ef785690a1b2c3dabdf99a9b3 .. . .. . This produces a nonce of : .. . .. . 587320654 -142251766 455884203 -543577677 0 .. . .. . So it creates 5 array elements Then the function increments the fourth element from -543577677 to -543577676 then -543577675 then -543577674 and so on . So it still works in a way but but does not increment as nicely as starting from 0 and is perhaps more error prone . When I passed in just a 96 bit random nonce the library automatically added the start counter as 0 to the end of the counter array and incremented it correctly for subsequent blocks . e.g . Comment : So it seems you don t need to set the counter explicitly because CryptoJS will automatically add it for you . It probably checks whether the last word is already 0 . Also CTR mode doesn t have an IV it is called a nonce . Comment : Also CTR mode doesn t have an IV it is called a nonce . Noted thanks . So it seems you don t need to set the counter explicitly because CryptoJS will automatically add it for you . Yes I tested this just passing in a 96 bit nonce and it automatically adds the start counter as 0 to the end of the counter array e.g . 587320654 -142251766 455884203 0 and increments it correctly . Many thanks for the response Artjom . Sorry I had tagged you because I saw your name attached to a number of the other CryptoJS answers and I figured you were knowledgeable on the library . Comment : Added a summary to the start thanks Artjom", "Question : I have a 1MB test file and I want to decrypt it starting from its 500KB not from the beginning .

With this script I can decrypt the file as long as its starts from 0KB . Could someone please explain me if it is at least possible Comment : Have a read of crypto.stackexchange.com questions 6170 http : crypto.stackexchange.com questions 6170 decryption-a-chunk-of-file-with-aes .. . Answer : In CTR mode https : en.wikipedia.org wiki Block cipher mode of operation Counter .28CTR.29 a counter 128 bit for AES is encrypted to produce a key stream that is then XORed with the plaintext or ciphertext . Usually it is assumed that the IV is either 64 bit or 96 bit and the remaining bits are actually set to 0 . The initial 64 or 96 bit are called nonce . The size of the nonce determines how much data can be encrypted in one go without creating a many-time pad : the larger the nonce the smaller the safe message length but also lower probability of collisions of two nonces when they are generated randomly . Since there is no specification how big the nonce is many frameworks don t limit the size of a nonce to a specific size . You can use the full block size for a nonce in mcrypt . .. . .. . You can .. . .. . 1 . take the IV that was used from the beginning .. . 2 . parse that IV as a big integer it doesn t fit into the PHP integer type .. . 3 . add to it a number which represents as many blocks 16 byte blocks for AES as you want to skip .. . 4 . convert the number back to a binary representation and .. . 5 . begin decrypting from a later byte . Steps 2-4 are accomplished by the add function in the following code . Let s say you have a big file but want to decrypt from byte 512 multiple of the block size for simplicity . You would add 512 16 32 to the IV . Here is some example code : .. . .. . Output : .. . .. . This also work in the exact same way for the OpenSSL extension in PHP . Here https : gist.github.com artjomb 50fcbf9acdfb97e1a3f8 is the code . .. . .. . Of course this would be a little more complicated if you want to get a chunk that doesn t begin on a block boundary . You would have to start a block earlier and remove the excess bytes . Comment : Thank you very much it totally worked for me . Your add function were what I was looking for although I have no idea how it works since I m not a encryption pro . Thanks Comment : The add function has nothing to do with encryption . It s a simple implementation of a little-endian encoded big integer counting . You can easily do the same with general purpose big number libraries like GMP but I thought you really don t need the overhead because addition is really easy to implement . This is basically the same as addition that you learned in school with using the carry and so on .", "Question : I would like to encrypt the cookies that are written by a webapp and I would like to keep the size of the cookies to minimum hence the reason I picked AES CTR NoPadding .

In addition what s the recommended size of IV for 128-bit AES How else is everyone doing this Do any tried and true ways exist I don t want to reinvent the wheel . Comment : Why should you care if the size of the cookie is made a few bytes larger .. . Answer : I dont have a direct answer for you question but a few things to add though . First of all encrypting the cookie does not make sense to me . If you want confidentiality of your data you shouldn t store it in a cookie anyway . If you want integrity i.e . not possible to tamper with the content of the cookie you should use a keyed hash HMAC for example . Another note is to never use a IV which is all 0 just for convenience . IV s are equal in size with of your block . In case of AES-128 the blocksize is 128 the keysize is 128 and hence the IV is 128 bits . The best way to do this is by creating a random AES key and using it as IV . This random IV may be public as long as it is not reused in subsequent encryptions with the same key .. . .. . edit : .. . .. . You may want to look at this wiki page for more info on which mode to use . However never use ECB unless you re sure you should use it . And even then verify with an expert . CBC is as far as I know the safest together with PCBC . http : en.wikipedia.org wiki Block cipher modes of operation Comment : A static IV kills the CTR .

The IV size for AES-128 is 128 bits . IIRC the IV is the same size as the cipher block . 128 bits is 16 bytes . 32 bytes if you store it as a ASCII hex string . Is that really too much 32 bytes in this day and age is not much at all.. .", "Question : I would like to encrypt the cookies that are written by a webapp and I would like to keep the size of the cookies to minimum hence the reason I picked AES CTR NoPadding .

In addition what s the recommended size of IV for 128-bit AES How else is everyone doing this Do any tried and true ways exist I don t want to reinvent the wheel . Comment : Why should you care if the size of the cookie is made a few bytes larger .. . Answer : CTR security requires that you never reuse an IV for two message encryptions with the same key . Actually it is even stricter : CTR mode works by encrypting successive values of a counter the IV is just the initial value for that counter and proper security is achieved only if the same counter value is not used twice this means that encrypting a value with an IV actually consumes a sequence of successive IV values which must not be reused with another encryption . The easy way to do that is to use a cryptographically secure-random number generator and create a new 16-byte random IV for every message . I underline cryptographically secure because that s import a basic random number generator is not enough . With Java use java.util.SecureRandom . With Win32 call CryptGenRandom . With a random selection the space of possible 128-bit IV is large enough that collisions are extremely improbable . Actually that s why AES uses 128-bit blocks thus implying 128-bit IV . The entity which will decrypt the message must know the IV so you have to store it along with the encrypted message . That s an extra 16 bytes . I understand that this overhead is what you want to avoid although 16 bytes is not that much for a cookie . The effective maximum length of a cookie depends on the Web browser but 4000 characters appear to work everywhere . A 16-byte IV when encoded in characters e.g . with Base64 will use about 22 characters i.e . much less than 1 of your maximum cookie size : maybe you can afford that Now we can get funky and try to reduce the IV length through trickery : .. . .. . Generate the IV with a hash-function : server-side use a counter which begins at 0 and is incremented every time a new IV is needed . To get the IV you hash the counter with a suitable hash-function e.g . SHA-256 and you keep the first 16 bytes of the hash value . The randomization properties of the hash-function will be enough to make the IV sufficiently random with regards to CTR requirements . This needs a cryptographically secure hash-function hence SHA-256 avoid MD5 . You then just have to store the counter value in the cookie and the counter will be shorter than 16 bytes e.g . if you have no more than 4 billions customers the counter will fit in 4 bytes . However there is a hidden cost : the server I suppose the server is performing the encryption in your system must make sure that it never reuses a counter value so it must store the current counter somewhere in a way which persists over server reboots and also does not fail if you scale up to several front-ends . That s not as easy at is seems . Use an external unique value : possibly the cookie could be part of an context which provides enough data to generate a value which will be unique to each encryption . For instance if the request also contains in the clear a user ID you could use the user ID as an IV source . The setup is similar to the one above : you get all that data stuff it into SHA-256 and the first 16 bytes of SHA-256 output is the IV you need . This works only if that data does not change for a given encrypted message and if it is really unique . This is a rare occurrence : for instance a user ID is good for that only if there is never a need to reencrypt a new message for the same user and if there is never a possibility that a user ID is reused e.g . an old user quits a new user comes and selects the now free user ID . Using a random 16-byte IV generated with a cryptographically secure PRNG is still the safe way and the one I recommend . If you find space tight in the cookie then this means that you are approaching the 4 kB limit at which point you may want to use compression on the data before encryption after encryption compression is very very unlikely to work . Use zlib http : zlib.net in Java you can access zlib through java.util.zip . Warning : in all of the above I am not saying anything about whether cookie encryption does help in providing whatever security characteristics you are trying to achieve . Usually when encryption is needed you actually need both encryption and integrity and then you should use a combined-encryption-and-integrity mode . Lookup GCM http : en.wikipedia.org wiki Galois Counter Mode and CCM http : en.wikipedia.org wiki CCM mode . Moreover cookie encryption is mostly good for one purpose which is to avoid the cost of storing server-side a bit of user-specific data . If you want to encrypt a cookie for something else e.g . to authenticate a valid user then you are doing it wrong : encryption is not the right tool for that . Comment : How about taking a hash of the data as the IV This still needs to be transmitted with the encrypted data but needs no server-side resources between requests and should give different IVs for different messages . Or is there a flaw with this scheme Comment : Using a data hash as the IV has two possible flaws : 1 . if you encrypt twice the same message then you get twice the same encrypted result and the attacker can see it . This may or may not be a problem in your specific context . 2 . Publishing the hash of the message as the IV allows the attacker to run an exhaustive search on the plaintext message : trying possible plaintext messages until a match is found . There usually are much fewer possible plaintext messages than possible keys . To fix that the IV should not be a hash of the message but say a MAC with HMAC . Comment : If you prefer computing the IV from the message itself is a sound idea but it requires some care . Also it prevents streaming encryption : you have to buffer all the data to first hash MAC it and only then can you begin the encryption . Depending on the context this may or may not be a problem .", "Question : It is possible to decrypt an encrypted video in AES CTR and and watching as it was being decrypted I want to decrypt Video hosted on MEGA.co.nz and go watching as that goes down without waiting for the download to complete .

It needs to be large enough for it to be very difficult to get duplicates . Be sure to put enough entropy into this number . Don t just use gettime . If you have access to CRNG then use it here .

So I enabled NSZombies and Now I don t see such error as expected As the objects are not de-allocated . But I don t find any useful NSZombie Log in the console . Is there a way to identify the issue .. . Answer : It s challenging . The most common cause of this error in Cocoa is directly accessing your ivars rather than using accessors . Accessors make the vast majority of memory crashes go away . That said they re not the only cause of memory errors . You may be accessing memory other ways . NSZombie does one specific thing : When you deallocate an object NSZombie says don t actually deallocate the object . Instead it turns the object into a zombie object that prints an error if you send it messages . But that only helps if the crash is due to sending a message to a deallocated instance . It could be lots of other things . You should start first with the crash stack itself . Look up the stack and see what kind of object it might be or who might be calling it . Read TN2124 https : developer.apple.com library mac technotes tn2124 index.html particularly the section on the BSD Memory Allocator and the Enabling the Malloc Debugging Features https : developer.apple.com library mac documentation Performance Conceptual ManagingMemory Articles MallocDebug.html section of the memory Usage Performance Guidelines . There are lower-level tools than NSZombie that you can use . MallocScribble is often the most useful . It overwrites deallocated memory with 0x55 so that you re more likely to crash sooner and to make it easier to detect deallocated memory in the debugger . MallocPreScribble is useful for finding uninitialized memory but this really only helps if you do raw malloc calls . ObjC objects are always pre-initialized . And of course you have to put on your detective hat . What parts of your program are most suspicious Are you doing multi-threaded work that can cause memory crashes if you don t lock correctly . If it reproduces easily then you ll figure it out . If it only happens occasionally well.. . I ve hunted bugs like that for many months sometimes . Sometimes it s just hard . Comment : App runs just fine with NSZombie . As you said NSZombie actually don t deallocate the object . Wondering If there is away to detech any attempt to reference that deallocated object . Comment : Not precisely but MallocScribble will help . Don t forget MallocStackLogging when you use that .

Comment : Setting an exception breakpoint won t help in the case of an EXC BAD ACCESS . Comment : NSZombie can be used any time it s possible to reference a deallocated object which is perfectly possible under ARC . ARC doesn t get rid of retains releases allocs deallocs autoreleases it simply adds them in for you .", "Question : I ve seen suggestions saying to set NSZombieEnabled to true while debugging . What is NSZombie Is it a framework A setting Comment : A undead NSObject beware Comment : An undead NSObject . .. . Answer : It s a memory debugging aid . Specifically when you set NSZombieEnabled then whenever an object reaches retain count 0 rather than begin deallocated it morphs itself into an NSZombie instance . Whenever such a zombie receives a message it logs a warning rather than crashing or behaving in an unpredictable way . As such you can debug subtle over-release autorelease problems without advanced tools or painstaking needle in haystack searches . You can read more over at Cocoa Dev http : cocoadev.com DebuggingAutorelease . The name is a fairly obvious play on the fact that objects are normally considered dead when they reach retain count 0 . With this setting they continue to exist in a strange half-life - neither living nor quite dead . Much like real zombies except they eat rather fewer brains .

Of course the problem is I cannot fall back to Xcode 4.0 because it refuses to run under Lion so I m in a pickle Any other bleeding edge developers using Lion who with more experience than myself can help dig this out Thanks . -Ric Comment : Do you mean Instruments or Xcode Comment : Instruments that came packaged with Xcode 4.1.. . as in Instruments 4.1 .. . Answer : There is another way to run with NSZombie on the device but this is done through XCode 4 not instruments . To run with NSZombie on the device open your XCode Project and click on the top menu item Product then hold down alt and click Run this will open a separate window where you will see Environment Variables in the bottom of the window .

I was later overwriting data past the array s bounds which should have been much larger than baseCells.count . Thank you bbum Question : I have a reproduceable EXC BAD ACCESS during NSAutoreleasePool -drain which seems to indicate that I am over-releasing an object . So I enable NSZombie but then the program does not crash any more . Nor do I get any info logged to the console . If I turn NSZombie off the crash comes back . What is the meaning of this I thought NSZombies were used to tackle exactly this kind of problem . If NSZombie won t help is there another way to interrogate this over-released object Also the crash is not reproduceable on Simulator which is why I can t use Instruments with NSZombie . Folowing is the backtrace at point of crash . .. . Answer : The problem you describe could be one of a couple of things you may be over-releasing an object or you might be corrupting memory . If you corrupt memory -- corrupt the first few bytes of an object specifically -- then it can easily manifest as a crash during an autorelease pool drain or any other message . That the crash happens on a device but not the simulator points to memory-corruption as well . The architecture of the device ARM vs . the simulator i386 is quite different and there are any of a number of issues that may be at play . Typically it doesn t manifest itself quite so consistently . First post the backtrace of the crash . It might help . Secondly do you do any kind of raw malloc calls Or filling buffers with data The most common cause of such crashes is running past the end of a buffer . .. . .. . The above was added after the OP fixed the problem but -- for the archive .. . .. . That crash trace is a classic signature of memory-corruption . Namely the isa pointer -- the first pointer s worth of bytes in an object that points at the Class of the instance -- was stomped . This typically happens when the you overrun a buffer of memory in the allocation before the object . If it is just a couple of byte overrun then the behavior between different platforms may differ since the malloc quanta -- the real size of the allocations you ask for 90 bytes on one platform and you might get 96 . Another 128 -- differ between platforms and even releases . In particular the isa was stomped with a value that looked enough like a pointer that the runtime dereferenced the garbage value and then tried to treat the resulting location as the Class s method table . Any time you see a crash that is a few frames deep into one of the objc msgSend functions it is quite likely memory-corruption and if so it will almost always be a buffer-overflow . Since it is easy to do it is still a good idea to do a test pass with zombie detection to catch the sometimes it is really just an over-release cases . Comment : Your suggestion was SO right . I had a buffer-overflow problem . You saved me hours possibly days of debugging . And I was looking hard for overreleases which didn t exist . Thank you so much . Comment : You are quite welcome . Comment : bbum demonstrates is awesomeness yet again : - Comment : Excellent debugging information particularly the points about how the results differ on the simulator and device duh in that I should have realized that and perhaps more importantly in different releases something I figured was unlikely . Thanks very much for all of the future time you ve surely saved me . Comment : In my case I am getting similar error messages .

Answer : I m looking at using susy-sass to build an entire website as opposed to bootstrap . Am I right in saying that the site has to be built page per pge . I mean if say on the home the aside tag as 3 columns and on the about page the aside tag has 4 columns you d have to write this style for each page I don t seem to find good referencws for building a whole site with susy . Thanks Comment : Susy is just a tool to help write CSS and it has almost no opinions about how you do that . Susy will have exactly the same constraints as writing the CSS yourself . If you want things to look different on each page you will have to specify that somehow but CSS is also good at handling global styles . It s up to you and your specific needs Comment : Thanks for that but would it need a stylesheet for each page then Is this the best practice @MiriamEricSuzanne Comment : No best practice is to use one stylesheet for an entire website or app . Comment : @MiriamEricSuzanne sorry what I meant was when building it you d need to style page per page as opposed to bootstrap where you have all the grid styles written out eg . col-md-2 all these grid styles would have to be done per page in susy right Comment : No with Susy you can do anything you want . You can build bootstrap with Susy if you want to - or your own version of something like bootstrap . You can also style component-by-component or page-by-page or any way you like .

Maybe . I m wondering about what s possible within Susy which may have separate mechanisms for achieving what I m after in a semi-straightforward way Comment : Susy doesn t have magic powers .

I came across a tutorial on a grid framework that I really want to use called Susy https : github.com ericam susy . However the tutorials I seen on it are all using it on Linux or mac and in some sort of a ruby based environment . Even on the site link I don t see instructions on getting it to work in VS2013 . I tried extension manager and nuget-package manager but to no avail . My only option seems to be to download the source and try to compile it by combining all the Scss files and hoping I do it in the right order . But something tells me I am getting a bit over complicated and there is a simpler way . There are many ruby Linux based libraries like this and I really would like to know how to bring this into VS2013 and later I can do it for any of the libraries I want . I am sure that people making the tutorials for such libraries and the libraries themselves are not excluding VS2013 purposefully if at all . I just don t know how to get them into VS2013 . Any help would be appreciated . Thanks in advance . Comment : Are you already using Sass If so how Comment : @EricMSuzanne - In visual-studio-2013 update 3 especially if you include the web-essentials extension . You simply create a .scss .sass file and web-essentials takes care of the translation to css . You have 2 windows side-by-side the sass and the translated css . Then I simply bundle my css file in the bundles.config which takes care of the minification . All that s left is to use it as normal in the header . Comment : +1 I have VS2013 update 2 with web-essentials and I was unable to include susy . Web essentials may have trouble compiling it Comment : @FrancisRodgers So did you get Eric s solution to work Can we get an update Comment : @JasonFrank - I have since moved on to another project and left that far behind . However I do believe SO requires me to accept an answer if it works . So I will check out his solution this weekend and let you know by Tue at latest . .. . Answer : You can use Susy anywhere you use Sass . Rather than using a gem bundle or any of the other linux-based approaches copy and paste the entire Susy sass directory into your own sass directory then import it into your stylesheets . You can treat all of Susy like any other sass partial . Comment : Thanks for your answer . It will be a week or so before I am working on that project again so I ll let you know if I was able to get it working . Thanks again .

Answer : To the best of my understanding https : github.com ericam susy issues 339 Sass-Rails is still using an older version of Sass that does not support Susy 2 .

I tried to use last-flow : to and it doesn t seem to be responding either . .. . Answer : Using the span mixin http : susydocs.oddbird.net en latest toolkit row-edges you can specify first or last and Susy will remove the extra gutter where relevant it depends on your gutter-position setting . All it really does is set margin-left or margin-right to 0 so of course there are lots of ways to deal with extra gutters depending on how you re using Susy .

So i must use Masonry as well but it messes my layout always . Sass : .. . .. . Javascript .. . .. . Has anyone done that before This is the masonry script i am using : http : masonry.desandro.com .. . Answer : I ran into this issue a little while back . If you check the masonry docs http : masonry.desandro.com options.html columnwidth you should see the option to pass an element selector as the columnWidth setting to masonry . Using this you can have susy tell masonry the widths of your elements . One thing I struggled with though was using gutters . In the end I resorted to using susy s inside-static method and used inner elements to provide styling . I ve put together a basic codepen http : codepen.io jackw pen ZYVgwq that should help explain things . Below is the scss for reference . Comment : Thank you but i gave up on Masonry .

I know there are lot of posts with this question but I m having 0 luck finding any regarding Breakpoint.scss and Susy 2.0 on this topic .

I m trying to stay DRY so adding a susy-breakpoint in my styles does not help . I ve also tried below code but I think I just have an error somewhere cause it s not working . .. . Answer : I don t know what your media mixin does so I can t really comment on anything related to that . Your initial example doesn t work because Sass CSS and therefor Susy are not aware of the DOM - or relationships between media-queries . When you change the value of susy inside one media-query that does not propagate to all similar media-query contexts . Because of that you do have to set both the media-query and the desired layout every time you want a breakpoint to change the layout context . susy-breakpoint is not the only way to do that but it is the shortest . Here s the longhand : .. . .. . Your small breakpoint currently doesn t change anything because it is identical to your default layout . The larger ones will-change the layout context for nested code though you can simplify : Since 1 4 split gutters aren t changing at all they don t need to be re-stated at every breakpoint . That will be identical to the longhand above . Comment : This answered so many of my questions going from SUSY One to SUSY 2 within about 90 seconds of CodePen . Thank you .

Comment : Thanks for helping : D .. . Answer : You don t have to pass the explicit context to every single container span element if you set it globally . Susy and any other Sass plugin is not aware of the DOM and so it is not aware that object1 is inside grid which has been set to 8 columns . Every item needs context from somewhere . If you don t pass it in explicitly Susy checks the global settings which default to 4 columns . If you change the global setting to 8 then you don t need to pass context into your mixins . The with-layout mixin is just one way to change the global setting temporarily for a block of nested code . Comment : Thanks Eric you rock I remember reading about the DOM .

Answer : If you use Bundler it will ensure that the gems in your Gemfile are the ones used by your project . So your Gemfile should specify susy 2.1.1 and sass 3.3.2 plus any other that you require such as breakpoint 2.4.1 . It then won t matter what versions are installed inside your Ruby gems folder . When you then do a bundle install Bundler ensures that your project will only use the correct dependencies . This is of course a CLI instruction through the terminal .

I was able to put together a simple game pretty quickly but I ve since run into issues . I was initially developing on a Mac and then switched to my work computer which is a Dell PC . On my Mac I was able to test my game using the simulator in Unity . Since I switched to my PC I have been unable to connect from my phone to the webserver in the debug simulator . The phone gets through the Enter the Code screen the developer console makes a connection noise but then my phone just sits at the Loading.. . screen . I ve reverted back to the Pong sample project to confirm that my code is not the problem . I ve tested the phone using both Chrome and the AirConsole app .

If I run the simulator in Browser Start Mode Virtual Controllers the controllers on my PC load fine but I m still not able to connect with my phone . I m using AirConsole v1.3.0.b which was still the most recent version when I posted this . .. . Answer : Steps to resolve this issue : .. . .. . 1 . Start the game using the simulator . 2 . Make sure the virtual controllers of the simulator load your controller . 3 . If that is the case try to load the controller.html directly in the phones browser . Assuming your run your game on in the simulator using http : www.airconsole.com simulator http : 192.168.0.2 : 7834 then take the part behind the and append controller.html . In this example try to load : http : 192.168.0.2 : 7834 controller.html on your smartphone . Note that this controller wont be working - it s just to try if the page that AirConsole loads internally works .

Answer : Concerning changing the controller layout . Instead of changing the file just change the displayed content in the controller.html .. . .. . E.g . you can make a container element for each gamepad you want to show . And then broadcast a message to all controllers when they should change the visibility of the containers . For example in your controller.html : .. . .. . In javascript also controller.html .. . .. . Now you just need to let your controllers know when to show-hide which container . You can do this by listening to onDeviceStateChange events . Comment : I m still pretty new to Airconsole so thanks for the insightful response . I understand up to the very last part you have : Now you just need to let your controllers know when to show-hide which container . You can do this by onMessage or listening to onDeviceStateChange events Are you referring to the onMessage in the controller.html file or the logic c-sharp file like in the pong game github.com AirConsole airconsole-unity-plugin blob master https : github.com AirConsole airconsole-unity-plugin blob master Assets AirConsole examples pong ExamplePongLogic.cs . Could I not make let says the start button toggle this or would this cause problems Comment : Well basically both . Your game unity code needs to tell the controller when to display which container-div . This means you can for example use .setCustomDeviceState container : gamepad-1 in unity and then in your controller listen with onDeviceStateChange and check the custom data .

Looking at the Basic Example scene and script which comes with the plugin will also help you figure out how the AirConsole functions can and should be used within Unity . If you are completely unfamiliar with the Unity Game Engine I recommend starting with generic Unity tutorials and then moving to AirConsole when you have the basics figured out . Comment : Thanks it helps", "Question : Airconsole says they use WebRTC if available . IIRC WebRTC provides both TCP and UDP options to send data . How do I choose which one to send over using the Airconsole API I d expect to be able to send things like controller inputs over UDP but things like controller state changes switch to the name input UI over TCP . Also can I detect when I have a direct WebRTC Game to Phone connection In that case it seems like I should be able to ignore the 10 messages per second limit . .. . Answer : AirConsole is always using TCP WebRTC data channels . UDP can not be specified in our API . The WebRTC mechanism is meant as an latency improvement that is nice to have but is not guaranteed . The AirConsole API abstracts all of this for developers - WebRTC messages behave exactly like WebSocket messages or long-polling messages and we apply the same restrictions for consistency e.g . the rate limit . AirConsole messages are always guaranteed to arrive . You could of course still open your own UDP WebRTC connections inside your game between the phones and the screen and use the AirConsole messaging API to do the handshake . We don t recommend this because iOS does not support WebRTC as of today and therefor the gaming experience would suffer a lot on iPhones and iPods . Comment : Thanks . I understand that iOS doesn t support WebRTC as of 2 2015 . I m designing games with asymmetric controls . People that can get fast updates play different roles than people that can t so being able to tell which controllers go going directly peer to peer and can therefore go much faster would be a big help .", "Question : I just downloaded the UnityPackage to try AirConsole in my project and I want to use the joystick controller example that is provided on GitHub .

Comment : Ah I see . AirConsole is something I hadn t heard about before . I wonder if something needs to change on their end . It might be worth contacting them about it . As the way crossdomain policy works is that the remote domain--in this case AirConsole.com--needs to supply the xml file on their server root the application needs to request it prior to making the request for any other asset . If that file doesn t exist is incorrectly configured i.e . does not include the domain the request is made from or the request for it is not made you will get the error you are seeing . Comment : Thanks for the info : - Yes I hope to reach the developers this is why I tagged it with AirConsole . I think they indeed have to put the file on their side so that my app is able to get the picture . .. . Answer : Thanks for the report .

When I click the Open Exported Port after the build it doesn t work too except for once . One error message I got once : Uncaught TypeError : Cannot read property postQueue of undefined .. . .. . This error message appears always : pre-main prep time : 176 ms UnityLoader.js : 1 Module.printErr @ UnityLoader.js : 1 .. . .. . Do you know what these error messages mean Comment : The Uncaught TypeError message should indicate a line of code in your controller file which might help you find the issue . Apart from that : are you sure you ve imported everything correctly Comment : You mean the import of files into Unity I ll have a look .

Answer : I ve tried a lot but this seems to solve the problem : Be sure to attach the event-listeners in the Awake method as they do in basic example application . My problem was that my AirConsoleService was static and not a MonoBehaviour to be sure that there is only one instance of AirConsoleService . It works perfectly for the debug play mode but in the release build the AirConsole somehow does not know the deviceID which sent the message this means we get -1 from method ConvertDeviceIdToPlayerNumber . And this explains why the controllers don t get any signal from the screen . My solution : I ve attached it as a component to the AirConsole object . Further notes : .. . .. . Anti-Virus may block content . Your PC server has to be fast . During development log the deviceID and the playerID and the current active deviceIDs . Often restart Unity or the integrated webserver of the plugin", "Question : When we launch our game in the AirConsole the RAM usage jumps really high and we get an Out of memory error . The only way to actually test the game is to upload a Development build with exceptions enabled and the WebGL Memory Size set to 2047 . That s the only scenario when the game doesn t crash . We used Chrome to monitor the RAM . When we launch the game in the AirConsole the RAM gets heavily loaded 2 GB or so and after the game loads the RAM usage becomes much lower about 1 GB . I think it is directly connected to the huge JS file that we get when we make a WebGL build but that s only a guess . How can we diagnose the problem and lower the RAM usage Comment : I shifted the question s focus to what are the tools for diagnosing memory because how to reduce memory consumption is too broad for SO - it cannot be answered in anything less than a book and for your specific case an answer would require your full code . Comment : You may instead rather wish to ask if there s a higher level tool specifically for WebGL or whatnot . .. . Answer : Well you need to profile memory usage by the page with the tools a browser provides - just like you would do for a desktop application . JavaScript Memory Profiling - Google Chrome https : developer.chrome.com devtools docs javascript-memory-profiling .. . MemoryBug Firefox extension https : getfirebug.com wiki index.php Memorybug .. .

I am a newbie Comment : Thanks by the way", "Question : Specifically is it possible to draw a line on your phone and pass that shape to the screen Or can I only have buttons on the controller . Thanks .. . Answer : Your controller is a mobile-website . That means you can have everything a mobile-website can also do such as buttons touchevent swipe gestures functionality touchmove etc see e.g . hammer.js use device motions camera .. . So if you manage to draw lines on a mobile-website you can also use it for an AirConsole controller . Just keep in mind the latency : drawing lines in realtime on your phone and displaying it on the screen may have some delay . Also sending messages on a touchmove event is a limitation .", "Question : I just downloaded the UnityPackage to try AirConsole in my project and I want to use the joystick controller example that is provided on GitHub .

It s still the testing period of the pro-version but the foundation version also seems to offer what I need . Apparently both recent versions smartSVN and Tortoise can open the same Repository . smartSVN also comes with a better graphical user-interface in my opinion though it s a little hard to learn for a beginner that you have working-copies working copy files etc .

Answer : To answer the second part of my own question both qsvn and rapidsvn can be used to view the logs when I ve already checked out a working copy . In qsvn go to Menu - Working Copy - Add . In rapidsvn go to Menu - Bookmarks - Add Existing Working Copy . Viewing the log is much slower than in git as explained by @Raghuram . Comment : In rapidsvn I didn t find a way to see commit messages + changed files with diffs on the same screen . gitk not on a specific file is REALLY useful for flipping through recent changes to see what s been happening .

Answer : It s probably the icon to show that the file is not in your repository . To remove them you ll need to delete the working copy delete the .svn directory from your home-directory assuming you don t already have a legitimate use for that and then delete the bookmark from within RapidSVN .

Putting the Keyword inside your file surrounded by dollar signs . Like this : .. . .. . This will expand to : .. . .. . Are you doing all of that The whole idea of keyword expansion is now considered an out of date concept that wasn t really all that good an idea . As long as your code is in Subversion you can get all of this and more without doing Keyword expansion . A lot of time this was used to see what versions of the software was used in compilation . However if you re compiling code there are simply better ways of embedding in the revision data . For example you probably are using a build-system that creates build-numbers . A better thing to do is to simply embed the build number in a single file as its compiled so you can view it in an About Box . So if you really can t get this to work it isn t all that bad . It s saving you from a practice that is no longer considered a good idea for CM ." ] }

As this quote from MSDN indicates : .. . .. . Important Any code written in an external assembly for use in a scripting functoid needs to be thread safe . This is required because multiple instances of a map can use these .NET instances at run time under stress conditions . The Mapper will reuse instances of external assemblies . In a utility assembly my team was using we had the following code : .. . .. . This was causing storereferences from one file to be mapped to different files . I appear to have fixed this by decorating the private field with ThreadStatic .. . .. . My question is - does anyone know of any issues with this in the BizTalk Mapper I m aware that there are issues using ThreadStatic in Asp.Net for examble due to threads being reused but can find no documentation on the way the BizTalk mapper deals with threads . .. . Answer : I have used ThreadStatic to set a variable is custom receive pipeline and then access its value within BizTalk Map through a helper class . have not got any problem so far - tested with 50 invocations in parallel .", "Question : I m using Hadoop s map reduce to parse xml files . So I have a class called Parser that can have a method parse to parse the xml files . And So I should use it in the Mapper s map-function . However it means that every time when I want to call a Parser I need to create a Parser instance . But this instance should be the same for each map job . So I m wondering if I can just instantize this Parser just once And just another add-on question why the Mapper class is always static Comment : In a distributed-computing environment sharing instances of a variable isn t possible.. .

I haven t written mapreduce recently but here s the explanation stackoverflow.com questions 11570674 http : stackoverflow.com questions 11570674 why-declaring-mapper-and-reducer-classes-as-static Comment : In this example code the Mapper is static-class . link https : hadoop.apache.org docs current hadoop-mapreduce-client hadoop-mapreduce-client-core MapReduceTutorial.html Comment : +1 cricket 007 . Need not be static except its inner class . above link by cricket 007 describes When declaring mapper and reducer classes as inner classes to another class they have to be declared static such that they are not dependent on the parent class . @Yilinkg Liu : In your example also your class WordCount2 is driver where all other classes were nested . Isnt it Comment : The Mapper and Reducer need to be static unless they are nested in the driver program primarily because the main method is static . I was correct that they are not always static as-in you can write MyMapper.java MyReducer.java and MyDriver.java and non of those contain static-classes . .. . Answer : To ensure one parser instance per Mapper please use mappers setup method for instantiating your parser instance and clean using cleanup method . Same thing we applied for protobuf parser which we had but need to make sure that your parser instance is thread safe and no shared data . Note : setup and cleanup method will be called only once per mapper so we can initialize private variables there .

Sample Input Output .. . .. . Currently I am checking Contact-Type Home then mapping the output through a value mapper to a script functoid for data confirmation before mapping the output . This seems to be causing duplicate nodes . .. . Answer : Have you considered using XSLT in your mapping Not only a lot easier to use than the BizTalk mapper also a lot more flexible and widely used you can use XSLT natively in a lot of products . An appropriate XSLT would result in something like the following : .. . .. . This should loop through the first 3 contacts and list them accordingly . Let me know if this suits your needs .

Could you explain the test position lt 4 . The map has mainly been completed with functoids script nodes etc . this is a minor updated that we need to cater for so was looking for a solution within the map . Comment : This is to iterate over the first 3 contacts only which is one of the requirements as far as I can see . the sign does not translate well into xml so I escape it . I know you prefer a mapper solution hence the disclaimer . It is possible however to include this but you would need to convert your mapper to XSLT Use validate map output xslt .

The first cluster has 5 nodes and a replication factor is 1 while the second one has a replication factor is 3 . If I run my map job should I expect any change in the performance or the execution-time of the map job In other words how does replication affect the performance of the mapper on a cluster .. . Answer : EDIT : This part of my answer is obsolete now that the other answer was edited : The other answer is not entirely correct . This was meant to address the incorrect implication that less replicas fewer paralelism . The rest of my answer below still applies . Any node can execute your tasks regardless of whether the data is located in that node or not . Hadoop will try to achieve data locality preference order is : node-local then rack-local then any node but if it can t then it will chose any node that has available compute capacity to run your task . Performance wise in a typical multi-rack installation rack-local performs almost as good as node-local since the bottleneck occurs when transmitting data across racks . However with high-end networking equipment i.e . full-bisection bandwidth then it wouldn t matter if your computation is rack-local or not . For more details on this read this paper http : www.cs.berkeley.edu ganesha disk-irrelevant hotos2011.pdf . How much performance improvement can you expect from having more replicas and thus achieving higher data locality Not much 5-20 maximum improvement . But this is an upper limit when you implement additional popularity-based replication as in this http : assured-cloud-computing.illinois.edu sites default files PID1974767.pdf and this http : www.cs.berkeley.edu ganesha euro118-ananthanarayanan.pdf projects . NOTE : I did not just make-up those performance improvement numbers they come from the papers I linked . Since vanilla Hadoop does not have these mechanisms in-place I would expect your performance to improve at most 1-5 . This is just a ballpark guess but you can easily run some tests yourself . The reason for this is that more replicas could improve the performance of some of your map tasks the ones that are now able to run with a data-local copy of the block but it would not improve your shuffle and reduce phases . Furthermore even if just one mapper takes longer than the rest this one will determine the length of your whole map phase so for many jobs it is likely that increasing locality will not improve their running times at all . Finally I O bound jobs can be map-input IO bound shuffle IO bound map output heavy or reduce output IO bound . Only the first type map-input IO bound would benefit from locality . More details on MapReduce workload characterization in this paper http : www.eecs.berkeley.edu ychen2 professional MapReduceWorkloadMASCOTSPublished.pdf . If you are further interested in this you can also read this paper http : www.cs.berkeley.edu ganesha pacman nsdi12.pdf in which they improve the running times of mappers but having the input data of ALL the mappers in memory . Comment : The question was what effect replication would have on the mapper and this is a big question because data locality has been found important see citations to performance . A better understanding of the OP s workload is needed . Comment : Ok I get that . But let me explain better : A single mapper can see its performance improved by data locality . However the map phase I guess this is what he means by map job will not be affected by this since the map phase duration is affected by stragglers single tasks that take longer for whatever reason . That is why it doesn t really matter . I am not making this up . I ve tested 100 locality easy to do just use replication factor number of nodes in cluster and observed the results . Improvement is minimal at the job level the reason for this is : stragglers + shuffle phase .", "Question : I am wrote 2 mappers Map1 and Map2 .. . .. . Map1- reads a seq file in HDFS and processes it . Map2- reads from HBASE and produces same key-value pair as Map1 . Finally I merge them in ReducerAll . The problem is that only one of the mappers is running and the job completes wihtout any kind of error . Only the last mapper is running i.e TableMapReduceUtil . If I exchange the lines TableMapReduceUtil and MultipleInputs then the last one i.e . MultipleInputs mapper runs . What am I doing wrong here No errors are thrown for both scenarios . I also read 2 files using addCacheFile for processing but that does not matter here I guess . .. . Answer : I believe the behaviour is because of the following two lines : - .. . .. . 1 . There is only one job job3 .. . 2 . Although you have mentioned that there are two mappers look at the mapper types . The mapper in Map1 would be different from Map2 . Map1 is a Mapper and Map2 is a TableMapper .. . 3 . Keeping the two statements together does not mean that they are essentially clubbed in a MultipleInputs setup for job3 . The MultipleInputs still only has one setup for Map1 . The other setup of Map2 is still separate . 4 . Now for the execution . The latter of the two configurations MultipleInputs or TableMapReduceUtil overwrites the previous one in the job3 and hence only a single mapper executes .. . .. . PS : - Please let me know if this is incorrect I am yet to validate my understanding I have presented here on my machine . Comment : Ah I understand now . So if I want to run both mappers and direct it to the same mapper should I define another job But then how will I be able to give it to the same reducer Comment : direct it to the same reducer Comment : @gambit I think we can use three jobs . First two jobs with only mappers and a third job Merge step with a plain Mapper that practically writes the input to output as is and then a reducer that actually does a merge task on these files .

There is an issue on GitHu https : github.com mikeedwards83 Glass.Mapper issues 81 b which would make it easy to create a custom attribute to handle this very easy . Currently you need to create a new type mapper and copy all the code from the SitecoreQueryMapper . I have written a blog post here http : ctor.io shared-field-references-in-glass-mapper about how you can create a custom type mapper . You need to create the following classes example for the SitecoreQuery . New configuration : .. . .. . New attribute : .. . .. . New type mapper : .. . .. . And configure the new type mapper in your glass config mapper and parameters for the constructor : .. . .. . You can then simply change the SitecoreQuery attribute on your model to SitecoreSharedQuery : .. . .. . For the children you could either use the shared query mapper and querying the children or create the same classes for a new SitecoreSharedChildren query . Edit : Added bindings for IEnumerable ISitecoreQueryParameter as they are missing and therefor it threw an error . Comment : Thanks Kevin . It is quite tricky to get this to work . I haven t tried this and will give it a try . After puting more thought into it to me it seems that Glass mapper is sort of doing the right thing . Otherwise how would you handle scenarios where Content don t want to show certain items in that langauge and if we are forcing it like this then we will never be able to achieve it . I know that if we use Fallback module than it helps it by putting setting the tempaltes for which version enfrocing is required . Comment : In addition I think that this solution gives us some flexibility and we can choose to have this behavior for certain templates . So it is definitely worth a try and thanks again for taking your time to document it . Hopefully I will give it a try in day or 2 and mark it answered . Comment : Couldn t resit and tried it I am getting this error When I register the component : Can t create component Company.GlassExtensions.SitecoreSharedQueryTypeMapper as it has dependencies to be satisfied . Company.GlassExtensions.SitecoreSharedQueryTypeMapper is waiting for the following dependencies : - Service System.Collections.Generic.IEnumerable 1 Glass.Mapper.Sc.DataMappers.SitecoreQ ueryParameters.ISitecoreQueryParameter Glass.Mapper.Sc Version 3.2.2.44 Culture neutral PublicKeyToken null which was not registered . Comment : Also Just to calrify I tried to register before and after container.Install new SitecoreInstaller config but same result . In the SitecoreInstaller class I do see these components being registered . So not sure what is going on . Comment : @TMalik did you read my blog post ctor.io shared-field-references-in-glass-mapper http : ctor.io shared-field-references-in-glass-mapper There is a bit a better example on how to register the mapper . And you are completely right with your first comment . You should not use this mapper for all your properties . We use this property only if all items we want to map only have shared fields and therefor don t need a version in each language . Otherwise consider to use the normal SitecoreQuery attribute .", "Question : How to map User class to UserModel class using Emit Mapper There several problems : .. . .. .

Let s suppose that I have type A with a collection of type B and I would like to map it to AMapped with a collection of BMapped...how should I setup the configuration should I use PostProcess I really like the idea of this library but it really misses configurations and examples.. . Comment : It depends on the type of the collection .

But I cannot find related samples after search . Appreciate if anyone could point me to related code snippet . Thanks . BTW : is gzip has the same feature multiple mapper process different parts of one gzip file in parallel . .. . Answer : If you look at : http : comments.gmane.org gmane.comp.jakarta.lucene.hadoop.user 30662 you will find that bzip2 format is indeed splittable and multiple mappers can work on one file . The patch was submitted at : https : issues.apache.org jira browse HADOOP-4012 . However it seems it is available only above HADOOP 0.21.0 . From personal experience in order to use this technique of bzip2 there is nothing different that you need to do . hadoop should pick it up automatically depending on your min split size . bzip2 compressed data by blocks and therefore it is possible to decompress it in blocks and send each block to a separate mapper . However gzip does not have such a technique and therefore this cannot be sent to different mappers . Comment : Thanks Varun However gzip does not have such a technique and therefore this cannot be sent to different mappers . -- is there any Hadoop document claims that Comment : As I stated it is not possible to decompress gzip in parallel unless you have already decompressed that same file once serially and built a map of entry points or the gzip file has been specially prepared for parallel decompression which requires custom software for that purpose . Comment : @Varun Shingal does one has to add bzip2 to hadoop in order to use it or does it come shipped with hadoop by default thanx Comment : @theexplorer Hadoop has supported this by default I think since release 0.21.0 in 2010 .

The installation process uses NuGet and on completion I can successfully see all tests in the MS Test Explorer . However if I start a new solution and reference all the required XUnit dll s i.e . I want to use XUnit without using NuGet to install it the tests never show up in MS Test Explorer no problems seeing them in the ReSharper test explorer . I think this has something to do with the XUnit test adapter that Visual Studio uses to find XUnit tests . It appears that NuGet somehow instructs Visual Studio to create the VisualStudioTestExplorerExtensions folder on each build putting the necessary XUnit test adapter dll s e.g . xunit.runner.visualstudio.testadapter.dll in that folder . The MS Test Explorer then uses this test adapter to find XUnit test see SO Question http : stackoverflow.com questions 29399970 visual-studio-and-nuget-based-test-runners-adapters . When I attempt to use XUnit without NuGet the VisualStudioTestExplorerExtensions folder never gets created on build . Adding the folder manually with all XUnit dll s in it also doesn t work .

Answer : Your problem is the upgrade of the Pimple container . The Pimple version of Silex 2 freezes services once you get them https : github.com silexphp Pimple blob master src Pimple Container.php L116 .

The only scenario I can see where use app wouldn t work is if you define some entries in separate files . What follows is just if you are curious .. . .. . The advantage of passing the container again in the parameters is that it allows Silex to pass another container instance instead . Silex doesn t do that so it doesn t affect you . But some other containers do . The main reason for a container to do that would be if you have a complex setup with multiple containers that are chained one after another : ParentContainer - SubContainer . When you define an entry in the SubContainer you want to be able to fetch dependencies from the parent container which will automatically look in the subcontainer too . So the subcontainer will pass the parentcontainer in the closure parameter . That s an advanced and rare use-case but it s interesting to know Comment : Thanks . I thought about possibility of passing different container in a parameter but couldn t find any practical way of using this .

The framework provides a tag library decoupled from the view technology . In this section we describe each tag in general terms such as the attributes it supports what the behaviors are and so forth .

Whenever a tag doesn t have complete support for every language it is noted on the tag s reference page . .. . The types of tags can be broken in to two types : generic and UI . Besides function and responsibility the biggest difference between the two is that the HTML tags support templates and themes .

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 .

Answer : I m planning to install Jet brains resharper for assembly browsing but not sure if it is paid or free to use with Visual Studio express edition . Can someone please help me to know this Comment : Resharper is only available as a paid product . If with Assembly Browsing you mean looking at the decompiled sources then JetBrains dotPeek is a free solution . As alternatives you could also look at Red-Gate Reflector .NET and ILSpy . Comment : Also you cannot install and load extensions in VS Express . use VS Community instead .", "Question : I have a project that uses both PHP and Python and I would like to use JetBrains IDEs in this case PhpStorm and PyCharm to work with both languages . However when I open the project using both IDEs concurrently I get a pop-up whenever I switch from one to the other as the newly focused IDE detects metadata that has been written to the project directory by the other IDE . I imagine this would be a problem between other combinations of JetBrains IDEs as well hence the use of the generic jetbrains tag . I have a work around I will post in an answer for others to view but it is somewhat awkward to set up and I may well be working with other projects that use the same combination of languages . Is there an easier solution Comment : Yes -- use full IntelliJ IDEA -- supports all languages via plugins except AppCode CLion AFAIK . Other than that -- your solution is the only one too keep .idea subfolder project settings in separate places . Comment : If I can get stuff that I thought was PHPStorm specific PHP debugging support phing build tasks etc . working in IntelliJ then this solution would be perfect for me as I have a full tools licence . I d dismissed IntelliJ as solely Java other JVM languages previously . Comment : It should be the same at least that s what they state . . plus there are many people that use it this way . AFAIK when you launch IntelliJ IDEA for a first time at one of the steps it will ask what other technologies except java-oriented you want to activate -- PHP Python Ruby should be there on a list at least this is what I remember when testing it over 1-1.5 years ago . if not -- PHP Python plugins can be installed manually via standard plugins interface . Comment : In the past . . when every product had separate release cycle . . the PHP support in IntelliJ could lag behind a bit . . but these days . . with unified versioning and release cycle it s no longer the case . The possible downside -- PhpStorm has simplified project configuration structure and therefore should be easier to use for new users for sure . Also there are some rare cases when something works in PhpStorm but does not in IntelliJ -- but I personally remember only few tickets like this I ve been PhpStorm user since v0.6 or so Comment : If you can use IntelliJ -- definitely try it and see how it does for you . .. . Answer : My current workaround : .. . .. . Create a new directory separate to the main project directory - using the language specific IDE for the second-most used language in the project-open the new directory as a project and using the options in Settings Project Project Structure add the main project directory as a separate content root . Whenever needing to work on the parts of the project written in the secondary language you can now open the new directory instead this keeps metadata for both IDEs separate .", "Question : This seems to be an error with the JetBrains Resharper 9.1 Ultimate Test Runner referencing an older version of NUnit .

Comment : Off the top of my head . Some browsers internet-explorer included tags files as Downloaded from the internet . Opening up such a file will run it with reduced access rights could this be the culprit Please try right-clicking the original file in your Downloads directory and picking Properties the seeing if there are some funky stuff near the bottom of the dialog box along these lines and then if you can remove this Downloaded from the internet flag does the installer then appear to work Comment : @LasseV.Karlsen I tought about that one too . But when I copy it to my desktop it works fine and when I copy it back it doesnt work again .

Comment : It does not sound as-if you have made any attempt to solve this . What have you tried so far Comment : Yes i have made an attempt and included in the demo but when check in the IE version it fails to load and then in search for the solution .. . Answer : UploadiFive is for HTML 5 browsers that support the HTML 5 file API . IE 9 does not support the HTML 5 File API . The first version of IE that does is IE 10 . Use the older and free uploadify instead on older browsers . It uses a flash plugin to do the same job .

Answer : I finally got the work around when you see the var-dump of the response from a normal file posting form via blade Laravel approach you will find the Uploadfile object is created with the name of file specified in the form field but on the other hand when you send the same request via Uploadifive you will find that it sends an array which include a node called FileData which holds an object for that file so basically you need to assign that object pointer to the file variable like this and it will work perfectly : .. . .. .

Answer : You need to supply more details about the embedded platform . Embedded platforms vary widely from desktop computers especially about their resources such as file systems I O memory capacity and hardware layout addressing . For developing a WinCE application you must confirm that the platform supports a file system . Many embedded systems don t . Next you should research on how WinCE is set up to execute a C function : does it use Windows WinMain tmain wmain or main Also you need to research how parameters are passed to the program .

Comment : What does the signature declaration of your main function look like Comment : @Reuben : Now I ve added it to the question . .. . Answer : The main function of a Windows application can take one of a few different forms . There s WinMain http : msdn.microsoft.com en-us library ms633559 28VS.85 29.aspx there s main and wmain http : msdn.microsoft.com en-us library aa299386 28VS.60 29.aspx . In your case you ve written a WinMain function that takes classic main parameters i.e . argc and argv . I d recommend that you switch the name of your function to main and confirm that your Visual Studio project is correctly configured for the correct application entry-point . Comment : Now I got this : unresolved external symbol WinMain . Comment : Are you compiling a console-application or a Windows GUI application Comment : I ve selected WCE Application . Comment : I m not familiar with this particular version of Visual C++ but Visual C++ Studio usually has an option to pick a GUI a.k.a . Win32 application vs . a console-application .

Answer : You need to add the path to the directory where ostream file resides to the list of the compiler include paths usually -I directive . Comment : Either edit the Addintional include directives in C++ section of the project properties or if you start the compiler from the command-line use -I command-line option . Comment : Is there a graphical interface and a project Or do you just edit files and then start compilation from the command-line Comment : There s a minor problem : I ve never in my whole development experience have seen the eVC++3 . However the problem you face is quite simple and typical but the details you provide are very vague . It doesn t matter whether the program will be command-line or not . I ask you how you start compilation - from IDE or from the command-line Comment : From the IDE of course Comment : Then there must be some setting in the IDE that tells the compiler where to look for header-files . It should be called somehow like include directories .

Question : .. . Did any one faced same problem and have safe solution if yes please provide me some example or give some guide .. . Answer : It looks like you are currently pre-iOS8 triggering an alert view from within your view object . That s pretty bad practice as in general alerts should be triggered from actions and logic . And that code should live in controllers . I suggest you refactor your current code to move the logic that triggers the alert to the correct controller and then you can easily upgrade to iOS 8 by using self as the controller . If instead you re calling the alert from an outside object then pass in the controller to the method that calls the alert . Somewhere upstream you must have knowledge of the controller . Comment : +1 for suggestion you are right place for calling UIAlertView is wrong but in current state i can not refactor it i found same problem in many place waiting for suggestion with less modification any ways thanks will apply your logic if no other suggestion came . Comment : have u find the solution yet Comment : Previously UIAlertView has been working from any UIView or NSObject . For ex : Showing alert from UITableViewCell works . There is no need to show it from UIViewController instance . Now UIAlertController presents only from UIViewController which is not easy to show alerts from cells . Comment : in general alerts should be triggered from actions and logic . And that code should live in controllers . - I prefer to put my business logic away from the view controllers in my model . The controllers should only handle the visual side of the views they.. . control . So this all just doesn t make sense . Comment : @Jonny business logic lives in business classes but display logic lives in display controllers . When a display controller calls business logic that returns an error it is up to it to determine how to display it to the user . I hope that makes it clearer .", "Question : I am used to customize UIAlertViews through the alert setValue : someView forKey : @ accessoryView method .

That s the problem @huey is getting because he s compiling on xcode 5 UIAlertController will not be recognized . If you are using the most recent SDK your answer is the correct one because when a phone running ios7 runs your app built with ios8 it will just return nil on UIAlertController class . Comment : right so @huey shouldn t try to compile on xcode 5 . he needs to use xcode 6 and use your code to prevent calling UIAlertController if a device uses ios7 . my comment was meant to point out that the reason it s not compiling is that the class is not available on the ios 7 sdk . however your first response said that it will work on ios7 and xcode 5 which is not true if that class is not available .", "Question : I have working iOS application In order to support iOS8 I am replacing UIAlertView UIActionSheet with UIAlertController .

This was possible with UIAlertView but perhaps not quite proper . In this case how do you present a UIAlertController right there in myUtilityMethod Comment : Would be great if you accepted the answer by agility vision . .. . Answer : You can try to implement a category on UIViewController with mehtod like - void presentErrorMessage And and inside that method you implement UIAlertController and then present it on self .

In that way you ll avoid unneccessary parametrs and warnings about view not being in window hierarchy . Comment : Except that I don t have myViewController in the code where the bad thing happens . That s in a utility method which knows nothing about the view controller that called it . Comment : IMHO presenting any views thus alerts to the user is the responsibility of ViewControllers .

And it turned out to be exactly the same as accessoryView used to be for UIAlertView the difference being that you need to assign a UIViewController to this property rather than a UIView . That piece of code will show a red view on the alert view Happy UIAlertController customizing .. . .. . PS . It is a private property but using KVC there shouldn t be a problem App Store wise I think . Edit : .. . .. . Some people complained that this isn t very safe . It s not a public API so yes Apple could change it in any release causing this method to fail . To make sure your entire app doesn t crash if that happens you could wrap the KVC call in a try block . If the property changes your controller won t show the content view but it also won t crash : .. . .. . Using this method in production can be risky and I don t recommend it for important alerts . Comment : You can override -preferredContentSize to return a custom size in the view controller that you are setting as contentViewController . Comment : Like I said in the answer because you re assigning it via KVO it can t and won t be detected by Apple s static analyzer and so it will pass the reviewing process . Comment : We did something similar using KVO to access the buttons on a UIAlertView a few years ago . Then they changed the name of the identifier and all our IAPs stopped working on iOS 8 . Not a fun few days rushing out fixes for 20 apps . I heavily advise against this solution Comment : Question is what do you strongly suggest instead Comment : I suggest not bothering to shoehorn this functionality into the native alert .

Answer : Solution for checking iOS version in Swift .. . .. . Con of this solution : it is simply bad practice to check against OS version numbers whichever way you do it . One should never hard code dependencies in this way always check for features capabilities or the existence of a class . Consider this Apple may release a backwards compatible version of a class if they did then the code you suggest would never use it as your logic looks for an OS version number and NOT the existence of the class .

Comment : Do not use if NSClassFromString UIAlertController nil because it works correctly on the iOS simulator using iOS 7.1 and 8.2 but if you test on a real device using iOS 7.1 you will unfortunately notice that you will never pass-through the else part of the code snippet .

Comment : UIAlertView and UIActionSheet has been replaced by UIAlertController in iOS 8 have you looked at this Comment : Make sure the class that self belongs-to adopts the protocol UIAlertViewDelegate the recommended way to do this in Swift is with an extension . Comment : iosdevcenters.blogspot.com 2016 03 http : iosdevcenters.blogspot.com 2016 03 uialertcontroller-in-swift.html .. . Answer : If you re targeting iOS 7 and 8 you need something like this to make sure you re using the right method for each version because UIAlertView is deprecated in iOS 8 but UIAlertController is not available in iOS 7 : Comment : Or you can save time and just use UIAlertView until you drop support for iOS 7 . Apple won t reject your app for that . Comment : Deprecation doesn t mean don t use this or that it would be the wrong method it just means it will not work later on . There s no need to specifically use UIAlertController on iOS8 if one just needs basic alerts . They will work as before . There are many APIs that have been deprecated in iOS4 or 5 and still work in iOS8 . But of course apps targeting a higher iOS level should not use them and that s why there is a deprecation-warning . Comment : @SamiKuhmonen No but it makes it clearer why you re doing what you re doing and makes it easier to remove support for deprecated methods when your minimum version is high enough to do so .", "Question : I m porting my app to iOS 8.0 and notice that UIAlertView is deprecated . So I ve changed things to use a UIAlertController . Which works in most circumstances . Except when my app opens it does several checks to report various states back to the user.. . .. . .. . E.g.. . Warning you haven t set X up and need to do Y before completing projects and Warning you are using a beta version and do not rely on results etc.. . these are just examples Under the UIAlertView I would say get two alert boxes concurrently which the user has to tap twice to dismiss both...but they both appear . Under UIAlertController with the code below to present a general alert I only get one alert message along with a console message : .. . .. . Warning : Attempt to present UIAlertController : 0x13f667bb0 on TestViewController : 0x13f63cb40 which is already presenting UIAlertController : 0x13f54edf0 .. . .. . So although the above probably isn t a good example I m thinking there may be times when more than one global alert may need to be presented due to events whilst operating an app . Under the old UIAlertView they would appear but it seems they will not under a UIAlertController . Can anyone suggest how this could be achieved with a UIAlertController Thanks .. . .. . Edit : I notice that on iOS8 presenting two AlertViews consecutively they are queued and appear sequentially whereas in iOS7 they appear concurrently . It seems Apple have altered UIAlertView to queue multiple instances . Is there a way to do this with UIAlertController without continuing to use the deprecated but modified UIAlertView Comment : did you have any luck in finding an answer to your question Comment : Sadly no . At the moment Im sticking with the apparently modified UIAlertView . Time constraints prevent me investigating further . Comment : Do we have any solution for this issue Comment : I just posted my solution check it out below . Comment : UIAlertController is more and more looking like a less than half-a ed job to me . .. . Answer : I fully understand the issue here and came up with the following solution via a category of UIAlertController . It s designed so that if an alert is already being presented it delays showing of the next alert until it receives a notification that the first has been dismissed . UIAlertController+MH.h .. . .. . UIAlertController+MH.m .. . .. . This code even handles the case where a previous alert was presented via the deprecated UIAlertView i.e . it waits on it to finish too . To test this out all you need to do is call show twice in a row with two different alert controllers and you will see the second one waits until the first has been dismissed before being presented . Comment : super viewDidDisappear : in your code will not do what you probably think . It won t call - UIAlertControl viewDidDisappear : but that one of the direct superclass - UIViewController viewDidDisappear : . As you can t know what is in the implementation of - UIAlertController viewDidDisappear : that you are omitting this is not dangerous this is a bug . There is a hacky technic to access the original implementation of a method from the override in the category search for method-swizzling but it is really overkill - go for the subclass approach . Comment : Thanks the docs are ambiguous about that and even thought I had tested it but must have been mistaken . I updated the code to swizzle the method and tested via a subclass and it is working . I m going to stick with the category because I m confident I ll eventually figure out how to achieve this without the swizzle or retaining the window . Comment : Looks nice based on the golden words method-swizzling and your SO scores.. . but did anyone successfully use this yet Is it safe Can I leave my kids in front of it while I go do something else Comment : Just another method I was thinking.. . subclass UIViewController add a - void showUialertController : UIAlertController alert or similar which underneath the hood carries out the queuing . Not sure if we d have to care about UIAlertViews then . Comment : Sometimes you want to show alerts from classes other than view controllers though .", "Question : I am using Swift to write an app and I need to show an alert .

Answer : I was annoyed that I kept having to write out both situations so I wrote a compatible UIAlertController that works for iOS 7 as well so I just threw it up on GitHub . I did my best to replicate the much better methods of adding buttons and actions of the UIAlertController . Works with both Objective-C and Swift . I m posting this as I found this question when searching on Google and figured it could be helpful for others . https : github.com BayPhillips compatible-alert-controller Comment : Good idea I m using your library and it makes maintaining compatibility with alerts a lot simpler . Comment : Glad to hear @Paludis . I d love any feedback as well as any PR s to make it more fully featured Comment : Thanks just found this and it works a treat" ] }

Be careful that once your program got a SEGV you re on shaky ground i.e . your cleanup might fail as well and generate another SEGV etc etc so you should consider just crashing with a core .

Answer : Its not possible to reliable run any code after you have encountered a SIGSEGV . You might get away with it sometimes but you can t trust your program to work as intended afterwards . If for example you have a SIGSEGV because of a corrupted heap you will have problems if your 3rd party lib is cleaning up any memory . To get a reliable solution i would think about if you really need to run that cleanup code or if there is another way to handle the situation check for an unclean shutdown on the next startup .. . .", "Question : Is it possible to restore the normal execution flow of a C program after the Segmentation Fault error I want a mechanism similar to NullPointerException that is present in Java C etc . Note : Please don t tell me that there is an exception-handling mechanism in C++ because I know that dont tell me I should check every pointer before assignment etc . What I really want to achieve is to get back to normal execution flow as in the example above . I know some actions can be undertaken using POSIX signals . How should it look like Other ideas Comment : Where do you want to return control to after you got a nullpointer exception Comment : it would be best to return control to the first instruction that follows the one that caused the sigsegv but any other safe place is appreciated . Comment : There is no normal execution flow after SIGSEGV . The fault might have happened in something like if p 12 and since p is undefined your program will continue to run as-if you had written if random 1 0 Comment : @Marc the reason you shouldn t do this is that you have literally no idea what the state of your program is after a segfault . Your stack may be corrupted your heap may be corrupted your global-variables may be squashed your instruction pointer may be in neverland your secure data may be flying over the internets your CPU might be on fire . You will regret trying to continue after a segfault as-if nothing has happened . The right way to handle calling buggy third-party code is to spawn a new process to call it--a lot more work but the only thing remotely reliable . Comment : I guess you are hoping the error inside the functions you can t rewrite is of little or none consequences to your own code . The problem with that reasoning is that as you said you don t have the sources . For all you know they could be writing inside your own allocated memory erasing your own data or even your stack . If this happen even using your own handlers won t get back your process memory to its correct state . Thus ignoring the segmentation-fault produced by their code will just delay until the next one raised from your code.. . I m so happy I m not in your situation.. . .. . Answer : In POSIX your process will get sent SIGSEGV when you do that . The default handler just crashes your program . You can add your own handler using the signal call . You can implement whatever behaviour you like by handling the signal yourself .", "Question : I m constructing a program which uses mprotect to restrict a block of memory from accessing .

Answer : You are looking for libsigsegv http : libsigsegv.sourceforge.net .. . .. . But beware that calling mprotect is only signal-safe in Linux other POSIX systems may not support this . I am afraid that in Linux the only way to get memory protection bits is to read in proc pid meminfo .. . .. . On a side note Linux only : If you are worried about memory consumption and intend to enable pages of a larger mapping one by one then I would advise to create your mapping using mmap with MAP NORESERVE in which case you will get a mapping to zero-filled copy-on-write pages which will allocate physical RAM on the first write . MAP NORESERVE instructs the kernel not to back your memory with swap space allowing you to allocate up to 64TB of virtual-address-space .

Answer : I think you should not try to run anything which cleans up in-memory state especially writing it to disc as-if successful you make cause data corruption . Recording some state information if possible may aid debugging but you should not rely on being able to .

Answer : You have to use sigaction with SA SIGINFO instead of signal to establish your handler and then you will get called back with useful information in a siginfo t including si addr . si addr as explained in sigaction 2 will contain the address . As for the length well you re out of luck unless you re willing to parse instructions .

The situation is : a large body of C code which I didn t write does most of the work in this application all the game logic and although it s well-tested on numerous other platforms it s entirely possible that I in my Android port will feed it garbage and cause a crash in native-code so I want the crash dumps both native and Java that currently show up in the Android log I guess it would be stderr in a non-Android situation . I m free to modify both C and Java code arbitrarily although the callbacks both going in and coming out of JNI number about 40 and obviously bonus points for small diffs . I ve heard of the signal chaining library in J2SE libjsig.so and if I could safely install a signal handler like that on Android that would solve the catching part of my question but I see no such library for Android Dalvik . Comment : If you can start the Java VM through a wrapper script you can check if the app exited abnormally and do the error reporting . That would allow you to cleanly catch all kinds of abnormal exits be they SIGSEGV SIGKILL or whatever . However I don t think this is possible with stock Android apps so posting this as a comment converted from answer .

Answer : In my limited experience non-Android SIGSEGV in JNI code will generally crash the JVM before control is returned to your Java code . I vaguely recall hearing about some non-Sun JVM which lets you catch SIGSEGV but AFAICR you can t expect to be able to do so . You can try to catch them in C see sigaction 2 although you can do very little after a SIGSEGV or SIGFPE or SIGILL handler as the ongoing behaviour of a process is officially undefined . Comment : Well behaviour is undefined after ignor ing a SIGFPE SIGILL or SIGSEGV signal that was not generated by kill 2 or raise 3 but not necessarily during catching such a signal . Current plan is to try a C signal handler that calls back to Java and somehow terminates the thread without terminating the process .

This doesn t generate the error I want . How should I go about doing this edit I don t handle segfaults at all but they are generated in my program if I remove locks . I want to use a lock-less design therefore i created a shared variable class that uses CAS to remain lockless .

Comment : @LightnessRacesinOrbit : So it would be ok to leave a shared resource permanently locked if the process which held the lock dies Your approach turns possible data loss into guaranteed data loss .

Comment : I need the signal to be generated by something like dereferencing an invalid pointer Comment : @RaptorIV : Explain why you care what it is that generates the signal . Comment : it needs to be generated in a real environment as though a multithreaded program had caused it . Im not handling it at all I just need to see my program crash because of it so i can see if it doesn t exist when i implement my class Comment : Raising the signal like that will with a few caveats get treated exactly like a real segfault the signal will get delivered the exception handler will be invoked if one is present . It s still a real signal in every sense and if it s for testing then it s quite a good starting point if nothing else .", "Question : When debugging a C++ program emit a SIGSEGV with gdb it is possible to handle the signal and asked to nostop . How gdb handles this kind of scenario Have searched gdb source code and couldn t find a starting point . .. . Answer : You cannot automatically ignore SIGSEGV . I also wouldn t recommend doing that anyway . Although you can make gdb ignore the signal and not pass it to the program the kernel will attempt to re-run the offending instruction once the signal handler returns and results in an infinite-loop . See this answer http : stackoverflow.com questions 8456085 why-cant-i-ignore-sigsegv-signal for more information . One way to work around it is to the skip the instruction or change register values so that it does not segfault . The link shows an example of setting a register . You can also use the jump command to skip over an instruction . Comment : Yes understood handling signal anyway and the question is how gdb does it self", "Question : I have to use c++ classes which is not properly written - there is no information if one function in loop is executed properly or not .

Is there any possibility Using signal handlers from include doesn t help . Comment : If something is segfaulting there s a very good chance that it s also scribbling over other memory . Continuing to run after a segfault seems like a really dangerous thing to do even if you find a way to make it happen . Comment : If you really truly have to use someone else s code that s so badly written it segfaults consider writing a separate program to do that communicating with yours via pipes or files or shared-memory or something . Then if it fails the damage it can do to the rest of your program is limited . Comment : siglongjmp out of the signal-handler to a previously set sigsetjmp Comment : @JSB Quit and find a better job . Being forced to use a library that crashes without the ability to fix it is unacceptable . When the desk in your office catches fire once a week the correct action is not to find an umbrella for the sprinklers . Same goes for code . Code is your work environment . Comment : A segment violation is either a signal of defective OS or hardware or your application invoking undefined behaviour . Concentration on the latter you can avoid this completely by writting correct code at least in the incriminated loop . Just get your code correct and there is no need to try catching UB . To state it very clear : If you get segfaults your code is broken .. . Answer : A segmentation-fault may happen in two ways : .. . .. . uncontrolled segfaults where a process is accessing addresses for which this access is not well defined . @JSB this is the case you re dealing with and there s little you can do about it other then getting the offending code fixed . .. . .. . When an uncontrolled segfault happens which is the case for buggy code in 99.999 of all cases the only reasonable thing to do is cover your losses you may write to already opened files from a SIGSEGV handler and terminate the process . .. . .. . @JSB the following does not apply to you This is just for completenes .. . .. . controlled segfaults where a process accesses addresses which are allocated by the process but read-write execute access is disabled . A controlled segfault may be induced in the following way .. . .. . So why is this a controlled segfault Because you can actually react to it in a sensible way . In the SIGSEGV handler you can set the memory protection of the pages which access caused the segfault to allow the access .. . .. . It is important to understand that this kind of SIGSEGV handler is well behaved and defined only if the segfault was caused by access to an actually allocated memory objects and if the signal handler action only sets memory protection flags on memory objects owned by the process . You can t use it to make broken code magically work .. . .. . So why would one actually do this One example would be client-side implementation of APIs that allow network distribution and also allow to map objects into memory like OpenGL which has the API functions glMapBuffer glUnmapBuffer . To avoid unneccesary round trips and transfer you d want to transfer only those parts of the buffer actually read from and or modified . For this you have to somehow detect which pages a program touches . Some OSs like Windows have a dedicated API for this but in nix-es you have to work with mmap + mprotect + SIGSEGV handler tricks to implement this . Comment : So I understand that I am lost and I have to write backup files every correct iteration . Comment : @JSB : No you have the option to get that rubbish code fixed or get rid of it and get your money back . Not sure how your company handles such problems but I have the strict policy not to accept broken code I pay for . I m very much for being tolerant but not when it comes to quality stability in production code . Comment : @Olaf This is University this is DAQ software for ASIC which uses their own custom data format which is slightly useless . They provide software to rewrite it to Cern Root tree however this tree is still usless without definitions from their class . This class have problems . We have to deal with it in another way . Comment : @JSB : Yes you re pretty much SOL . As a workaround you could try forking the inner loop into a separate process adding the trouble of somehow getting the data back shared-memory writing it through a anonymous pipe . Using any kind of workaround to implement this will be a kludge and come with a very noticeable performance hit . Comment : @JSB : I realize the tough spot you are in . As already told using a separate process is the only half-sane way to deal with this . You don t have to write a separate program for this . You can fork the main program just fine .

Comment : I guess you are hoping the error inside the functions you can t rewrite is of little or none consequences to your own code . The problem with that reasoning is that as you said you don t have the sources . For all you know they could be writing inside your own allocated memory erasing your own data or even your stack .

Answer : This glib http : www.gnu.org s libc manual html node Defining-Handlers.html Defining-Handlers manual gives you a clear picture of how to write signal handlers .

The list of other signals can be found here http : www.gnu.org s libc manual html node Standard-Signals.html Standard-Signals . Signal handlers are broadly classified into tow categories .. . .. . 1 . You can have the handler function note that the signal arrived by tweaking some global data-structures and then return normally . 2 . You can have the handler function terminate the program or transfer control to a point where it can recover from the situation that caused the signal .

Basically what s happening is that I am forcing the system to send me a SIGSEGV inside a background-thread . I handle that signal and then the test is over . The main thread will be waiting for this and part of the signal handler is to restart the main thread . When the main thread restarts I restore the default signal handler by signal SIGSEGV SIG DFL and then I get another SIGSEGV . I understand that I have a lot of code and this could very well be my fault but is there a common explanation of why a SIGSEGV would fire twice It is not happening when I cause other signals though I haven t tried all of them .

Check the following page for details . http : www.gnu.org software libc manual html node Signals-in-Handler.html .. . .. . You should also use reentrant functions inside the signal handlers For example localtime r instead of localtime . Moreover it is recommended to use sigaction instead of signal .

Answer : No it s not possible in any logical sense to restore normal execution following a segmentation-fault . Your program just tried to dereference a null-pointer . How are you going to carry on as normal if something your program expects to be there isn t It s a programming bug the only safe thing to do is to exit . Consider some of the possible causes of a segmentation-fault : .. . .. . you forgot to assign a legitimate value to a pointer .. . a pointer has been overwritten possibly because you are accessing heap-memory you have freed .. . a bug has corrupted the heap .. . a bug has corrupted the stack .. . a malicious third party is attempting a buffer-overflow exploit .. . malloc returned null because you have run out-of-memory .. . .. . Only in the first case is there any kind of reasonable expectation that you might be able to carry on .. . .. . If you have a pointer that you want to dereference but it might legitimately be null you must test it before attempting the dereference . I know you don t want me to tell you that but it s the right answer so tough . Edit : here s an example to show why you definitely do not want to carry on with the next instruction after dereferencing a null-pointer : Comment : +1 for calling the question out on wanting to do the wrong thing . : - Comment : thanks for the example but will this copy operation be performed I claim the OS will not allow this and send SIGSEGV instead . what is more assignment is not the only operation that violates memory . reading memory does not cause such threat . Comment : @MarcAnderson : that is not true . Read operations can also cause SIGSEGV . Comment : did I say they don t cause SIGSEGV The threat I mentioned applies to overwriting invalid memory location . Comment : @MarcAnderson : the copy operation may or may not be performed . aBuffer will contain a random value after recovering from the first SIGSEGV . If that random value points to protected memory e.g . is 0 or points into a read only segment it will raise another SIGSEGV .

I have two iPhones with some VoIP apps that allow me to specify Auth Name Auth Password Username Display Name Domain and SIP Proxy . In OpenSIPS i have created a domain with the IP of my server also i created two users on that domain and gave them Aliases of 100 and 101 . The software on the iPhones claims that it has registered with the OpenSIPS server so I have to accept that . I believe that my configuration of the Twilio SIP Trunk is correct on the basis that there aren t many settings to set and they all look correct and make some kind of logical sense . What i cant figure out from here and not for lack of searching the web watching hours of webinars etc is how do I get OpenSIPS to send outbound calls through to the Twilio Trunk and also get the handsets to ring on incomming calls and Twilio s SIP Trunk has a Termination SIP URI of xxxxxx.pstn.twilio.com which is im guessing supposed to be entered somewhere in to OpenSIPS but I cannot see how to configure this . I m looking for something that is a guide on how to connect OpenSIPS to the Twilio Elastic Sip Trunking service . Any help appreciated.. . .. . Answer : So I m guessing you want to set up an OpenSIPS instance which acts both as SIP registrar and basic SBC by simply forwarding all outgoing traffic to the Twilio SIP trunk . SIP Registrar .. . .. . It looks like you ve already handled the registrar part of OpenSIPS scripting . You can always generate a basic configuration that handles user registrations with : .. . .. .

Setting a destination URI then doing t relay http : www.opensips.org html docs modules 2.1.x tm.html trelay-1 will simply proxy the current request to the specified destination . For a more advanced routing mechanism i.e . you need to route to a bunch of trunks consider using the dispatcher http : www.opensips.org html docs modules 2.2.x dispatcher module which supports using an SQL table populated with SIP destinations . - managing incoming traffic .. . .. . the registrar module functions should be enough for this test with lookup http : www.opensips.org html docs modules 2.2.x registrar.html id294366 or registered http : www.opensips.org html docs modules 2.2.x registrar.html id294613 then just do t relay http : www.opensips.org html docs modules 2.1.x tm.html trelay-1 .

Can anybody please give me some idea to solve this issue Thanks Comment : please show your logs .. . Answer : More info would be useful . First make sure both clients are registered and can use at least one common codec . In most cases these aren t the problem . It s usually a NAT Firewall issue . Are the two clients on the same subnet Is there any firewall rules blocking the communication SIP signaling usually goes on udp : 5060 . But that seems working . Media is tricky . In each call the ports for RTP audio changes in the range specified in rtp.conf . This RTP traffic goes over UDP as well . By default it t 10000-20000 . If there is only routing done between the two endpoints it should still be fine . NAT Network Address Translation is your main concern . Take a look at iptables sip nat conntrack . To debug use asterisk s sip set debug on command and look for the SIP headers and verify the correct IP addresses . Comment : Thanks for the info .

You can check their wiki : .. . .. . http : www.kamailio.org wiki .. . .. . For understanding this case first you should learn how voip works subject . You already can not inrecept any SIP call with fiddler or wireshark . Generally SIP server managers hide their topology for security reasons .

Possible solution is truly websocket-SIP gateway .

In RTCP must both the two entities communicating in such a scenario send RTCP packets I am asking that because when i use the sipphone it sends some RTCP packets at first and then the server answers whereas the sipp scenario doesn t send rtcp packets at all and gets no response from that protocol . Also all the ports for RTP+RTCP are open both in the router and in the testing machine . Can an IMS server be configured to send RTCP packets one direction only on an RTP flow Does it say anywhere in the RTCP Protocol that a client has to send RTCP paskets to receive such packets from the server .. . Answer : You need to negotiate ports for RTP and RTCP first using SIP and SDP before those messages can be sent so if the server doesn t respond with any SIP message then something else is wrong . Please check all the IP addresses in the outgoing INVITE from SIPP . Comment : Of course and i set the RTP port in the INVITE and the proper IPs so the server sends his own RTP packets in the respected prespecified ports .

Step1 : check NAPTR SRV record optional but at least SRV is good to have .. . .. . In theory SIP Applications will do some NAPTR and SRV requests to locate your server for your service . This is described in rfc3263 https : www.ietf.org rfc rfc3263.txt and means you are supposed to configure your DNS entries to let SIP applications find the IP of your server . Check this page http : web.mit.edu sip sip.edu dns.shtml for an example Then you can test NAPTR for your service replace antisip.com with your domain-name .. . .. . Then use one the answers to test the SRV queries : .. . .. . In the example above sip.antisip.com and sip2.antisip.com are running the sip services for antisip.com .. . .. . Step2 : Without NAPTR SRV at least check DNS .. . .. . To make it simple if you have one server just make sure your domain resolve to your server s IP address : .. . .. . Note that for me antisip.com is also the sip.antisip.com server . Step3 : Testing from a windows .. . .. . The easiest from this point is to test on your favorite desktop OS . This will allow you to start a network capture . You can download this very simple demo . It s a very basic SIP app but that s easier for testing : VoipByAntisip.exe for Windows http : sip.antisip.com VoipByAntisip.exe .. . .. . Install wireshark and start it .

Of course you also need to test calls . The tutorial doesn t indicate that you need a rtp relay But usually if you wish to makes calls between SIP User-Agents an application relaying RTP like rtpproxy will need to be installed and configured to work with kamailio on your server . Without the relay you should be able to call talk between two SIP applications running on the same LAN . In order to test calls you will need to create a second user test2 and configure another PC to use this account . Then in Voip By Antisip for windows use the start call box and enter sip : test2@mysipserver.com . The network capture should show an INVITE being sent to your server . This INVITE should be relayed to second user and received by test2 SIP application . Comment : thanks for the brilliant explanation . I ve already started with installation of dns server 2 days ago .

During my research into doing this I ve come across sip over web-sockets which might be useful to me however I am unsure if a user-agent connecting through sip over web-sockets to a compatible server would then be able to successfully make a call to some one using an incompatible server i.e . calling from SIP over web-sockets to true SIP . I know webrtc2sip can be used for connecting to legacy networks but I would rather avoid using another proxy if at all possible . So is it possible to connect to a compatible SIP server using SIP over web-sockets then make a call from this user-agent to another that does not support SIP over web-sockets without using a gateway Comment : You could use a SIP server that supports both traditional SIP over TCP UDP and WebSockets to implement a gateway function . An example enabling technology would be Mobicents SIP Servlets see code.google.com p sipservlets wiki Welcome tm 6 https : code.google.com p sipservlets wiki Welcome tm 6 . Comment : Would making a gateway be as simple as just connecting the user agents though a proxy that supports both or would certain headers need to patched media encoded etc . Comment : The answer to this depends on the interoperability of your endpoints sipml5 and some other unspecified SIP UAs . To be clear you would need to implement a proxy in Mobicents SIP Servlets . The gateway function has to be done somewhere after all . .. . Answer : Mobicents SIP Servlets Example already provides a B2BUA Application taking care of that for you . The Media is peer to peer or through a TURN Relay Server but if you need to bridge to a Media Server you can indeed patch the SDP Body to make the media of each party go through the Media Server pending it supports Media related codecs from WebRTC DTLS-SRTP etc to add conferencing recording type of capabilities .", "Question : I m little bit confused about sip proxy and sip outbound proxy What is the basic difference between sip proxy and sip outbound proxy Is it mandatory to use sip outbound proxy along with sip proxy Can anyone point me out from the below image which one is the sip proxy and outbound proxy enter image description here http : i.stack.imgur.com N3Hr1.png .. . Answer : SIP Proxy .. . .. . A SIP proxy server receives a SIP request from a user-agent or another proxy and acts on behalf of the user-agent in forwarding or responding to the request . Sip Outbound Proxy .. . .. . An outbound Proxy : A proxy that receives requests from a client even though it may not be the server resolved by the Request-URI . Typically a SIP user-agent is manually configured with an outbound proxy or can learn about one through auto-configuration protocols . Basically they are the same the only difference is that SIP Proxy treats requests both for UAC client and UAS server but SIP Outbound Proxy receives requests from UAC . And no it s not mandatory to use SIP Outbound Proxy along with SIP Proxy . What about scheme from your image these are not proxy servers but are registrar servers which are used to register requests of the users and keep the information from these requests . Comment : So for sip registration which registrar server should I use Comment : do you own register server or have a sip account Comment : I own a register server .", "Question : There are some SIP Servers which handle few thousand subscribers and some other which can handle millions of subscribers with similar underlying hardware . What are the design and development factors to be considered for implementing SIP Servers which can handle such massive amount of traffic .. . Answer : First I m going to assume you re interested in building your own SIP signaling applications so your question is directed at SIP applications servers and the applications running on top of them . I m not going to talk about products like Asterisk . There aren t that many choices when it comes to Java app servers that include SIP servlet containers . Basically the big three are IBM s WebSphere server Oracle s Communications server and Mobicents . I m mostly familiar with WebSphere which you can download for free at www.wasdev.net but I m sure all of these products scale on the signaling side very well . Well beyond a couple of thousand endpoints and if you re willing to cluster the servers you could support into the thousands of calls per second fairly easily . This is how tier one providers like AT T scale their Voip services to massive numbers of endpoints . If you are including media processing in your question that is when you quickly start getting into scalability issues . Server-side media processing record playback multiway mixing SFUs etc . can be extremely processor intensive . In the SIP servlet world media servers are controlled via the media control API JSR 309 which delineates the signaling plane form the media plane . So its hard to provide an answer to your question without knowing more about the types of applications you SIP server needs to host . There are a lot of factors that can affect the scalability of SIP servlet applications that rely on a SIP servlet container . Threading is the key . You want to make sure you are never blocking threads in your application code . Everything must be asynchronous to scale . For developers not used to writing asynchronous code this can take a little getting used to but its critical to figure this out before taking on any real-time signaling development . In terms of Java servers you also want to tune your JVM for the best possible results . This goes beyond making sure you have enough heap space to accommodate the number of calls per second you server must support . There are many JVM Garbage Collection GC knobs that can be turned to adjust the nursery size etc . Its critical that the GC configuration is right for your server . Most JVMs also have specific GC algorithms that are designed to work better for real-time applications . For instance the JVM used with IBM WebSphere supports a GC algorithm called metronome which trades of GC activity for low-latency . This is an enormous subject so if you can provide some more details about what your trying to accomplish with a SIP server I might be able to provide more insight . Comment : Thank you for the detail explanation . The third paragraph in your answer is what I am more interested in i.e the coding techniques that should be used to implemented a scalable SIP server or other telecom software like LTE packet core EPC . It would be great if you can suggest books or papers that can guide me on building carrier grade software . Comment : This book on SIP Servlet 1.1 development looks like it has some good reviews and covers subjects like SIP clustering which are critical for scalability : amzn.to 1SlsU7x http : amzn.to 1SlsU7x Hope this helps .", "Question : I want to develop a Android App which will use a SIP Server of my client . My client is exposing couple of REST API from the SIP server for communicating with the apps . I want to know which would be the best codec type for this app Basically I want to create a SIP-Stack and send the SIP Packets to the Server . So there should be a coding and decoding system for the packets . My client prefers 16 kb sec but I am not sure which should I use . Comment : I am totally new in VOIP area .

So my client wanted to know the type of the codec i will use which I am not sure . I also have to fetch user s data using the API i mentioned earlier . Please suggest me the working procedure that I should follow . .. . Answer : It sounds like a bad idea to do it yourself . Developing a sip client is not a trivial task since there are several protocols you would have to implement . Choosing the coding is not very important decision compared to the rest . imho you should use one of the open-source sip stacks available like pjsip or build your application on top of an open-source sip client like sipdroid . But since you asked for codec : Use the GSM codec . Saved bandwidth and sounds OK . G.711 is otherwise the standard codec that 99 of all sip servers support . Comment : could you add any usefull information on the build your application on top of an open-source sip client like sipdroid . I m very interested in this . Thank you Comment : Take sipdroid change the GUI a bit and call it your own application . don t forget to keep their copyright info Comment : oh : it s sounds really easy but it might not be : P you re right about the copyright info they had issues in 2009 according to their wiki . thanks anyway", "Question : I have one simple question which stuck me .

EDIT : I have found this stackoverflow link here http : stackoverflow.com questions 27985127 jain-sip-webrtc-signaling . But the answer is not clear enough . .. . Answer : Socket.io is a different alternative protocol and it s not compatible with SIP over websockets . If you want to use SIP over websockets you can build both the server and the client part with JAIN-SIP stack as shown here JAIN-SIP WebRTC signaling http : stackoverflow.com questions 27985127 jain-sip-webrtc-signaling but you will have to ditch socket.io . You can also consume socket.io with your own client library from android without having to use SIP just as well for webrtc .

And there is no reason it should break anything in your app . 200 Ok for UPDATE has one meaning : the UPDATE was correctly received handled on remote side .

Its really important because other responses provisional and final might take a while for initial INVITE message as we have to consider the scenario of forking UE-B not reachable fallback.. . etc It might take some time . SIP over TCP : Timer-A will not be started by caller and thus no re-transmission of message . TCP being reliable not re-transmission required . Even then why do most implementation sends 100 Trying over TCP .. . Answer : There are few reasons that 100 Trying is still needed for SIP over TCP . 1 . Having a TCP Connection does not guarantee that the SIP Application is working or if its a SIP - Aware application at all . The 100 Trying provides you the feedback that your request is being processed by a SIP Application . 2 . The lack of 100 Trying can also be the right trigger for not just re-transmissions but to re-attempt to maybe a different server in the configuration . You may not want to elapse 32 seconds for every Server in configuration even when the connection is TCP . 3 . In deployment scenarios if there are elements like a SBC or Load Balancer the TCP Connection is established with them . The Application behind it can be a different entity and usually these edge elements pass on all messaging or generate messaging to indicate the call in action state .", "Question : I want to develop a Android App which will use a SIP Server of my client .

SIP is the Session Initiation Protocol and it handles the NEGOTIATION OF SESSIONS . The sessions then arae - in case of auio and video - are based on RTP and use RTSP for signalling . So your question indicates a REAL lack of knowledge of what you need to do - the real uestion is : you need a RTP compatible codec . Which is similar senseless . RTP is jsut a carrier protocol . THis is like asking what is a HTTP compatioble image format . HTTP does not care . The browser does . In case of RTP it means - RTP does not care . It can transport ANY data .

This is like dynamic NAT with one public IP can give access to Internet just one PC in a time . Please correct me if I m wrong . Comment : if you connected via pstn you have SINGLE port per single line but still can have same number of 2 lines . Any digital connection can support any number on any port . There are no any limit in network itself . Digital network can have 300lines capacity with same single number connected via sip or 10x PRI E1 for example .

Answer : Datalife Engine does not use smarty template-engine . It has it s on custom engine . The Flow of the cms its simple every article has a short story and optionally a full story . In the template folder you have a bunch of tpl files with build up the final page . main.tpl beeing the file called for every page you display . Now typically once you call the front page the main.tpl along with shortstory.tpl are called along with other blocks for the front page . the shortstory.tpl is build by the engine modules show.short.php file witch will call the db for the data or memcached if enabled and the data was cached replace the the engin tags with the necessary data like title and many others . You should really look at the documentation to undestand witch tags are found in witch section . One important think to note is that you cannot add php in the tpl files at least not out of the box but you can include files with php in them . I recommend heading over to dlestarter.com they are a good reference for documentation in English and pretty much the only once as well . They also have a forum where i look into sometimes .", "Question : I am DLE not uploading .

Comment : jsfiddle.net BHLmD 1 http : jsfiddle.net BHLmD 1 This is basicly what i have . As you know i can t use the tag xfvalue treyler in there so i have to use the iframe code itself .. . Answer : Ok by the looks of things you are having trouble with jQuery.bPopup.js http : dinbror.dk bpopup so here is a basic example which should hopefully point you in the right direction . HTML : .. . .. . JavaScript : .. . .. . CSS : .. . .. . In my example I have chosen to popup trailers via a button with a common class of trailerbutton . This allows me to use common JS code for all trailerbutton click events . I have also chosen to hide my YouTube iframe inside a div just below the button . Note that this has a class of hiddenTrailer which is hidden via the CSS . As you can see I store the ID of the trailer div I want to show for each button in the data-trailerid attribute . I also have a hidden popup placeholder called my-popup which again is hidden with CSS . When the user clicks the button the JS event is fired and the correct trailer is loaded into the content div in the ready and waiting popup based on that all important data attribute . Here is a JSFiddle http : jsfiddle.net vqJy4 . Note that I ve had to paste the entire jQuery.bPopup.min.js into the JavaScript window so scroll down to check out the real content . EDIT : .. . .. . Should you wish this to work for multiple posts you can do something like this : .. . .. . HTML : .. . .. . JavaScript : .. . .. . The updated line here is var trailerhtml this .next .hiddenTrailer .html - I am now using jQuery to select the next hiddenTrailer element i.e . - the one just under the button you pressed . See this updated Fiddle . http : jsfiddle.net vqJy4 3 Comment : It helps thank you : Comment : I got a problem i don t know if you can help . The button doesn t fetch individual content.. . what i mean is if the 1 post when i see the trailer of the 2 post it will be the same.. . But it should be another one Comment : @PedroLino - See my update - hopefully this will help . Comment : thank you for the patience . I ve tested but i don t think this will work in Datalife Engine . We call the posts using a tag named content . This tag retrieves the posts and uses a .tpl file that defines the style You could call it the default html for one post i guess . I m editing this file to put the code of the trailer . But i can only change one that will have to work on all : I ve puted the div trailercontainer but it doesn t work .

I just want to comment that my experience was that giving the .md file to pandoc rather than the .html file gave a better output . So it s worth to experiment . Comment : This is the closest I ve come to a good process as well . Is there any way of changing the figure text from plot chunk of .. . to something else Comment : pandoc is in version 1.12 even in my now outdated Ubuntu 13.04 .", "Question : My problem is similar to this post http : stackoverflow.com questions 18427446 how-to-maintain-html-internal-links-when-converting-with-pandoc but not identical . I somehow can t figure out the correct pandoc command-line parameters for maintaining resolving cross-document links when using a couple of interlinked HTML files as the input . Let s say I have two files chapter1.xhtml and chapter2.xhtml located in the home user Documents folder with the following contents : .. . .. . which contains a link-to the next document . and .. . .. . which contains a link-to the previous document . I used the following command-line parameters : .. . .. . And I got the following output : .. . .. . This problem also occurs when I select docx or latex pdf as the output format . I also tried to use relative links but nothing worked . What are the correct parameters for resolving cross-document links tl dr I.e . I don t want link references that contain the original paths I want them to point to the new output document . Comment : so you want the links to point to the markdown files I guess you ll have to write a pandoc filter http : pandoc.org scripting.html to change the links.. . Comment : Actually I don t need to convert to markdown I actually want to create docx pdf files with working hyperlinks . I merely chose markdown output to illustrate a problem that occurs with all output formats . pandoc should be able to parse and resolve all hyperlinks and make them point to the output file before generating the output file . Generating files with broken-links by default isn t very helpful . IMHO this is a major bug . Comment : if you know the name of the generated output files you can link-to them without any problem e.g . file2.pdf header-id .. . Answer : The problem is that your links contain absolute paths home user Documents chapter1.xhtml instead of relative ones chapter1.xhtml . I cannot imagine the ePUB file containing absolute paths and if it does the links in the file will only ever work correctly on your computer . So the solution will have to be fixing those ePUB files before feeding them to pandoc . Note that roundtripping from pandoc from markdown to epub and back to html works as expected : .. . .. . P.S . Using two input documents like : .. . .. . works as the pandoc README states : .. . .. . If multiple input files are given pandoc will concatenate them all with blank lines between them before parsing . So for the parsing done by pandoc it sees it as one document.. . so no wonder that cross-file links won t work . Comment : Thanks for your feedback . However your idea won t work because href ch001.xhtml foo is an invalid html URI . Comment : @NemoXXX in HTML5 it s valid.. . mathiasbynens.be notes html5-id-class https : mathiasbynens.be notes html5-id-class Comment : Since both documents are in the same folder I tested it without absolute path names . E.g . p a href chapter1.xhtml Previous chapter a br p and p a href chapter2.xhtml Next chapter a br p and I got the link format that you mentioned which appears to be indeed valid in HTML5 but it s not valid in DOCX ODT or LaTex PDF and will cause broken-links . Unless I get a better suggestion I ll simply switch to Calibre https : en.wikipedia.org wiki Calibre 28software 29 which doesn t break links . Comment : I just generated a LaTeX-PDF from the ePUB I generated with pandoc see in the answer and the link worked : pandoc foo.epub -o foo.pdf Comment : Unfortunately it didn work for me . BTW I used XeTex . So maybe this is a LaTex configuration issue . Can you please post the original ePub and the generated pdf file to a one-click file hoster dropbox and indicate the exact command-line parameters that you used Also include any customized LaTex templates or other non-standard files that were used to generate the output .

Markup language has to be reST Markdown or like them .. . there should be simple editor with preview for example Gedit3 + Markdown plugin or something like that .. . there has to be batch converter between many formats - just like Pandoc but with full markup language support .. . .. . Pandoc is great but unfortunately it doesn t support reST directives ex . ..container .. . .. . Right now I can t decide which markup lang is the best for me . I was using Markdown because I had quite simple Gedit s plugin to preview output during writing . Right now I m testing Sphinx because I have to find a tool to create good documentation and Sphinx uses reST . reST also supports custom directives and today I found out that container directive would help me a lot . I ve never tried Textile . I m trying to write almost all documents in some markup language - I d like to avoid DOC DOCX pure Latex but still I can t find the one . Some of them supports tables other with extensions another ones has no simple editor with preview etc . .. . Answer : The reference Python implementation of reStructuredText is docutils http : docutils.sourceforge.net which obviously has full support for the reStructuredText language specification and which Sphinx is in fact built upon . It is not as versatile as Pandoc but if you are looking for a full implementation of reStructuredText and are already using Sphinx then docutils may be a good bet . Some limitations of docutils to note : .. . .. . Less output formats than Pandoc . Only supports reStructuredText as an input format Pandoc supports reStructuredText markdown HTML LaTeX etc . One way only conversion Pandoc for example can convert say reStructuredText to HTML and then HTML to reStructuredText docutils can only perform the former conversion . I have never come across a markdown or reStructuredText editor with a built-in preview window . Docutils is very easy to script so should be more than suitable for batch-processing of text-files . I have seen a number of websites written in reStructuredText which use a simple makefile rule to build the HTML and deploy to a server .", "Question : I am using the IEEE citation style from http : www.zotero.org styles ieee with Pandoc in a project .

I am writing a Markdown Knitr document that has a main file article.Rmd and several child files that are included in the main file using Knitr s child chunk option . The child files are basically sections of the main article file just separated for easier editing and management . Throughout these child section files I use the citations http : johnmacfarlane.net pandoc README.html citations in the Markdown text e.g . @author title 1999 to cite various papers . The main file and each child file has a YAML header that provides the BibTex file location e.g . : .. . .. . Including this YAML entry more than once is not a problem see the readme on metadata-blocks http : johnmacfarlane.net pandoc README.html metadata-blocks . When I compile the entire document using Knitr a big Markdown document is created . I then use Pandoc with the --filter pandoc-citeproc option to manage the citations . Pandoc inserts nice citations and appends a list of the cited papers as references bibliography . Cool . As I write and edit the individual child sections I use the same citation compiling which produces the correct inline citations but unfortunately also appends the references at the end even though it s just a section of the larger document . I would like to compile these small child sections with inline citations but without the bibliography at the end . .. . Answer : There is a discussion on this topic at https : groups.google.com d msg pandoc-discuss nVk-uWY1in8 DxJecBenQn0J and there is an open pull request to add an option to pandoc-citeproc to suppress the bibliography at https : github.com jgm pandoc-citeproc pull 40 . In conclusion pandoc currently doesn t allow the bibliography to be suppressed . However it s relatively easy to create a custom CSL style that doesn t produce a bibliography .

Did I do anything wrong Comment : @Jdbaba read the documentation print.xtable and see the comment argument Comment : So here is the solution : print xtable yourtable comment getOption xtable.comment FALSE .. . Answer : If you do not insist on using a LaTeX HTML-only solution with the otherwise awesome xtable package you might achieve the same with Pandoc s markdown . One option is to add the caption manually http : johnmacfarlane.net pandoc README.html tables below the table or use my R Pandoc writer package http : rapporter.github.com pander : .. . .. . Then use Pandoc to convert this markdown file to HTML LaTeX docx odt or any other popular document formats . Comment : I m trying to use your nice pander package but couldn t find an option to control the position of a table s caption by default the position is below the table but I need above . I looked through documentation and on the Web but to no avail . Any advice I understand that I can produce caption independently as R Markdown text but then there is an issue of margin between the caption and the table . It would be nice to be able to specify both the position above below and the margin . Comment : @AleksandrBlekh having the caption above the table is not a valid markdown syntax it should stay below the table . On the other hand you can render that to be above the table image in e.g . HTML or LaTeX . For the prior use JavaScript for the latter I suggest the caption and floatrow LaTeX packages like floatsetup table capposition top Comment : Thanks for fast reply and nice suggestions One of the reasons I m trying to use pander and R Markdown format is to be able to produce multi-format output as needed . Going the format-specific route is not optimal in this regard no single codebase I actually implemented some stuff in a LaTeX-specific way and it took a while just for that . Can t imagine spending more time to support HMTL etc . Actually I found a solution : I need pandoc 1.13+ which contains this fix caption should be on top : search for table captions above tables here : johnmacfarlane.net pandoc releases.html http : johnmacfarlane.net pandoc releases.html . Comment : @AleksandrBlekh This fix sounds great but it seems to be LaTeX-only to me . RStudio has released some binaries : s3.amazonaws.com rstudio-buildtools pandoc-1.13.1.zip https : s3.amazonaws.com rstudio-buildtools pandoc-1.13.1.zip Anyway you can still use markdown with multiple output formats and captions above tables images but this way you have to develop your custom templates for HTML PDF etc . This is a one-time investment that you can use for all future reports so besides the above mentioned one-liner LaTeX call you d need also another one-liner JavaScript call in your custom HTML template to move caption above the objects . Comment : @AleksandrBlekh the changelog you linked above has the quote part below the LaTeX writer section so I think this update has nothing to do with the other output formats . Also I think the markdown specification of captions to have it below the table has not changed either .

Answer : Since Guava is more of a general purpose library that happens to have functional idioms and Functional Java is purely about implementing functional idioms in Java Functional Java sounds like a better fit with probably a more complete set of FP-like features . On the flip side I prefer Guava because it is more general purpose and therefore I find myself using several of the features that are unrelated to functional idioms . One of the problems with both libraries as noted on Guava s Wiki in the above posts is the vertical noise of anonymous inner classes for your functional objects . Another library that attempts to fix this via annotations and the APT is Jedi http : jedi.codehaus.org . Another approach that makes any of the above libraries Guava FJ or Jedi less-noisy without annotations is a library that I wrote Funcito http : funcito.googlecode.com inspired by the syntax of Mockito . It is more limited in what it can simplify at this point essentially wrapping single method calls but that s what I currently find myself doing most of the time already .

Answer : Guava s goal is not to provide functional idioms in Java . From the Functional Explained http : code.google.com p guava-libraries wiki FunctionalExplained Guava wiki page : .. . .. . Excessive use of Guava s functional-programming idioms can lead to verbose confusing unreadable and inefficient code . These are by far the most easily and most commonly abused parts of Guava and when you go to preposterous lengths to make your code a one-liner the Guava team weeps . .. . Please be sure when using Guava s functional utilities that the traditional imperative way of doing things isn t more readable . Try writing it out . Was that so bad Was that more readable than the preposterously awkward functional approach you were about to try Leaning too heavily on functional idioms makes not too much sense up to Java 7 as the overhead is too high see vertical problem http : cr.openjdk.java.net briangoetz lambda lambda-state-4.html . This will-change with Java 8 which will-change the way Java libraries and programs are design on the detail level . Things that make sense in Java up to 7 will be discouraged to some extent in Java 8 . This will motivate a new edition of Effective Java and a lot of new APIs . If you re trying to teach functional-programming it s probably better to stick to a more or less pure functional language . Every language that is a melange or emulation of FP and OOP will be a distraction . Comment : I should also point out the preceding sentence in that article : As of Java 7 functional-programming in Java can only be approximated through awkward and verbose use of anonymous classes .

How safe would it be to use such a library in an enterprise production app Is there a better way to add closures to Java currently Comment : You could try using scala or clojur instead .. . Answer : BGGA is still a prototype implementation not sure how comfortable you are putting prototype code into production . check out google collections http : code.google.com p google-collections it gets you closer to the goal albeit more verbosely Comment : Interesting but it doesn t seem to have anything like closures - just collections . Comment : Functional Java does not require BGGA but does support it . Comment : Google Collections does have a Function A B type and most of their collections implement a functor . Functional Java s collections implement functors as well as monads cofunctors and comonads . Comment : yes depends on what you are shooting for .

Google collection nicely fits that gap for collections in java way", "Question : I was reading the following question - How safe would it be to use functional-java to add closures to a Java production project http : stackoverflow.com questions 766745 how-safe-would-it-be-to-use-functional-java-to-add-closures-to-a-java-production and I had been thinking of using the Functional Java project http : functionaljava.org as well in my current project . I was wondering what are Stack Overflow s users experiences with using the Functional Java project In particular I m curious about some of these specifics : .. . .. . Did it increase code quality or clarity Improve productivity Reduce potential points of failure Impact performance .. . Answer : I ve been on a team that uses the FJ library and I know of others . On one team it was used as a replacement for a home-grown library that was less polished on another it replaced Google Collections . I also know some folks that copycat the source code from FJ to roll their own implementation . In my opinion if you must use Java you should be using something like Functional Java to make your life easier . Did it increase code quality or clarity Code written in a functional style is more concise hence more clear . The library comes with and encourages the use of immutable data-structures which improves quality . The library also encourages composition over inheritance which improves the reusability of your code . Improve productivity Definitely . Developers with more powerful tools are more productive . In my experience developers feel that first-class functions make programming easier and more enjoyable . Happy programmers are productive programmers . Reduce potential points of failure A more functional style of programming discourages mutable state which eliminates a large class of bugs . Also more powerful abstractions lead to less repetition which reduces the number of places where something is wrong . Impact performance There s no reason to believe that performance would be impacted one way or the other . The provided datastructures are designed for ease of use and expressiveness rather than performance but they re written optimally for what they are . As with anything else how you drive is more important than what you re driving . For example fj.data.List is a linked-list so it has O n random-access and concatenation therefore you avoid it for those purposes . fj.data.Stream has O 1 concatenation by comparison .", "Question : I am playing with functional-programming and in particular with Functional Java .

Unfortunately in order to do that an instance of OutputStream AND one instance of XmlSerializer needs to be created . The scope of the OutputStream is wider than XmlSerializer s which means that the only way I can see to be able to correctly handle both lifecycles within my IO monad is to carry both of them with me in a tuple closing OutputStream after having written using XmlSerializer .

Hope this helps .", "Question : In java.util we can use the containsAll method to compare two java.util.Set . What s the best way to compare two fj.data.Set Is there really any valuable benefit of using fj over java.util Comment : what is fj.data.Set Are you using libraries Comment : @exception1 I think it s a library called functionaljava.. . haven t really had much contact but i m always very suspicious about librarys that are reimplementing java basics like arrays and lists Comment : @exception1 I am totally with you on that unfortunately I am working on a codebase that s already using this functional-java heavily and I have to finish some code by tomorrow : once that s done I will have more time to go back and change everything But for now I need to find the best way to compare two sets without writing a whole new method to do the job of containsAll Comment : I can t really help because I haven t ever used this library . It seems to have nice features for functional approaches . But fj.data.Set and java.util.Set are incompatible and I can t find any conversion functions or something similar . At least the fj data types implement the Iterable interface the native one - there is also a fj interface - so you can iterate and check the entries yourself . Unfortunately the don t implement Collection - would have made things a much easier Comment : that was pretty much my conclusion I was hoping some magic answer comes through .. . Answer : To compare two sets use Set.subsetOf . So s1.subsetOf s2 if s1 is a subset of s2 in contains terms s2 contains s1 . To create sets use Set.set which takes an ordering of elements that is how to know whether an item is less than another so the set can be stored in a red-black tree . FunctionalJava uses the functional-programming FP approach - data is immutable . That makes the Collection interface inappropriate for implementing . Note all the mutation and updating of objects in the Collection interface in methods like add addAll remove etc . There should be better support for converting to and from java.util.Set but to convert a fj.data.Set to a java.util class call set.toStream .toCollection or set.toList .toJavaList .", "Question : I would love to use closures in Java .

Answer : Too old question to answer . Here we have lamdas in java8 to make your life easier .", "Question : I know one of the goals of pure functional-programming is to eliminate mutability and therefore to preclude side-effects . But let s face it Java is not a functional language even with all of the functional-programming libraries that exist . In fact it seems that some of the FP-libraries know and expect this . For instance in Functional Java there is the Effect http : functionaljava.googlecode.com svn artifacts 3.0 javadoc fj Effect.html class . In the Jedi FP library there is the Command http : jedi.codehaus.org javadoc jedi functional Command.html interface . This allows you to -- among other things -- apply a command-pattern with type-safety to elements of an Iterable without the nasty for-loop boilerplate . So the question is is there anything like that in Guava EDITED AFTER ANSWER ACCEPTED FOR CLARIFICATION .. . .. . I am developing a framework http : funcito.googlecode.com that helps with the vertical problem inherent in most Java FP-libraries under a certain set of circumstances . So I would not actually make the code example as shown above : i.e . explicitly declare a new class implementation of Command with all of its vertical-noise icky-ness simply for the purpose of immediately applying it right after the declaration . I was thinking more along the lines of the actual command-pattern where there may be several possible commands declared elsewhere and only one of them gets passed into the code which wants to apply it iteratively . Furthermore the goal of my framework is to make it more idiomatic to create functional-interface objects functions predicates commands other simple lambdas without simply moving the vertical problem elsewhere . I have long realized this is not within the scope of Guava . But as Command-like interface are available in other FP libraries I just wanted to know if an analog existed in Guava . A more complete code example using my framework might be something like this : .. . Answer : Nope Kevin Bourrillion the Guava project lead has said on Guava s functional features : .. . .. . The syntax sucks . At the same time this stuff is now has always been and will always be nothing but a stopgap measure until the right language change can come along at which time we can finally really decide on the optimal syntax and have functional-style programming start actually making lives better in Java for once . So I m undecided how much effort to put into the Function Predicate stuff it s in the library more because it sort of had to be not so much because we think it s a crown jewel . .. . .. . We will probably change our strategy significantly when Java 8 comes along but that won t be for a while yet . Also we haven t found many use cases for which we think the Command interface you describe would be the best solution . For example we think that your above code would be much better written as .. . .. . the old-fashioned way . We could potentially be convinced of the merit of Command but I think the for-each use-case is almost always better done the old-fashioned way . Comment : Why is the old-fashioned way better for commands but not better for filters and transformations Also I know the functional features are seen as stop gap until Java 8 but you have to realize that Java 8 is some time off and adoption of it will not be immediate . There are still projects stuck Java 5 luckily not mine . Comment : If you read the user guide http : code.google.com p guava-libraries wiki FunctionalExplained Caveats you ll see that we think the old-fashioned way is better for filters and transformations most of the time . Not all of the time -- which is why we provide those features -- but most of the time . Comment : In addition the original post s code appears to be an example of the very thing that makes the Guava team weep http : code.google.com p guava-libraries wiki FunctionalExplained . Comment : I have read that section ample times and I agree with it in principle but think that it is way too amplified . In my tastes it is much more readable my one-line way than what you showed not just because it s one line but because it actually reads more naturally . The example given in the Caveats section of the user guide is clearly one where you are combining a Function and Predicate . Also I make an FOSS library that helps produce Functions and Predicates that wrap existing getters in a single line . So there is definitely a net code savings too . Comment : @KevinWelker : There s a huge difference between this and filter transform . Filter transform do something that cannot be done using a loop : they produce a view in constant-time . A for-each like in your example is inherently replaceable with a loop .", "Question : I am playing with functional-programming and in particular with Functional Java .

Answer : I actually took great inspiration from Functional-Java s DB combinators https : github.com functionaljava functionaljava tree master core src main java fj control db to solve similar problems . I made my very own XML combinators and more from this pattern so its worth learning . You might find this discussion https : groups.google.com d msg functionaljava AMcLld-78fI KOoOzczRX4MJ on google groups useful . edit - replying to the comment : .. . .. . follow the code : .. . notice how you start a new connection using the StateDb https : github.com functionaljava functionaljava blob master core src main java fj control db DbState.java L41 see that you have a few options to start a connection one that eventually commits and one that eventually rollback . these are just two examples of things you can carry with the computation . Essentially every computation that you bind https : github.com functionaljava functionaljava blob master core src main java fj control db DB.java L103 a plain modaic bind could potentially carry information . here is an example i gave in the discussion above : .. . .. . So in this example you can pass extra information namely the sql query as a parameter to the function that gets bound . you could just as well had more parameters to runStatement . to put it all together you get something like : .. . .. . Hope this helps Comment : Nice thanks I am close too see how to handle this but I still don t see it . Basically following your page how can I handle the fact that I need to carry Connection with me to the end of the computation so that I can close it Comment : hey kap i tried answering your question in the body above. . Comment : I see now the Connection is carried as part of the DBState object and closed inside DBState.run passing from one DB Monad to another in the DB A .run final Connection c . Well this is acceptable for this kind of application but it is not very generic...for generic IO Monads I need to come up with another solution I guess following the DBState implementation though .

Comment : Different Objective of coding optimise secure or without crash I think you should read for example Java good practice book .

No but then who cares The JIT optimiser can take care of these things quite well nowadays . My question is how the JIT optimiser handles this in a way that it isn t necessary to return a singleton .

Any functions added after the future is complete happen synchronously .. . .. . So this seems to be a design pattern from functional-programming that we re jamming into Java . The important thing is that we can daisy-chain on delayed events which I understand is a feature more built into C 3.0 language but you have to hack together with Java classes .

Comment : This question should be merged or linked with What embedded-browser for C++ project stackoverflow.com questions 835201 http : stackoverflow.com questions 835201 Although that question is about embedding web browser engine with rendering stripped off . .. . Answer : Try to opt for Webkit as it is used by many different browsers Konqueror Safari and Google chrome . This makes Webkit more versatile and more adaptable to other needs . The development of Gecko is very tied with Firefox . A lot of modifications made to Gecko are done because Firefox dictates them . For instance Firefox 3 decided that it was going to block all self-signed certificates for security purposes . The implementation has been done into Gecko s engine which means that any application that decides to embed Gecko has this security-constraint added to them . If you can stay with Webkit as it mainly a rendering engine for HTML pages . That s been developed with the intention to be used among different web browser . While Gecko is primarily the rendering engine of a single browser which just happens to offer an API for embedding . Comment : I would also hasten to add that Adobe AIR uses WebKit .", "Question : Right now I m using the latest ABC PDF version and use the Gecko rendering engine .

Does anyone know about this Couldn t find much about this on the internet though I do admit that I find it hard to come up with the correct search terms . .. . Answer : By default ABCpdf will use the print-css media type whereas Firefox will be using screen this can be changed by setting the media property http : www.websupergoo.com helppdfnet source 5-abcpdf xhtmloptions 2-properties media.htm . If the differences are more subtle it may be worth taking a look at engine configuration http : www.websupergoo.com helppdfnet source 5-abcpdf xhtmloptions 2-properties 1-engine.htm .

Comment : The the good pages @Melad is talking about I learned were pages with frame s and iframe s which I guess are kinda like today s experimental CSS features and the whole idea of saying like Gecko would I guess be like Firefox starting to obey -webkit- CSS vendor prefixes because Mozilla got tired of developers only including the -webkit- prefixed rules and leaving out the -moz- ones .", "Question : Using the default TWebBrowser makes things easy to embed a web browser .

I don t anticipate needing to do anything too unusual with it but you never know . 3 . We re using C++ and would like to work with a well-designed object-oriented architecture if possible . 4 . Cross-platform is a must and good performance would be helpful in the long run we may end up porting to mobile platforms . Are there any considerations I need to take into account before making a decision Has anyone worked with WebKit or Gecko before If so are there any articles or tutorials I might find useful Update : .. . .. . Thanks for the responses guys . We ended up going with Qt 4.5 which includes WebKit . We re really pleased with it so far in fact I think Qt is probably the best UI framework I ve ever used the difference between coding with the native Win32 APIs and this is staggering . It s also real easy to learn the only major issue we had was getting used to the signals-slots paradigm . Comment : Are you or can you be open-source If no that may limit what you can use . I think WebKit is LGPL Those restrictions aren t too bad if you re closed source Comment : We re not far enough along yet to make that decision but it s certainly a possibility . Comment : This question should be merged or linked with What embedded-browser for C++ project stackoverflow.com questions 835201 http : stackoverflow.com questions 835201 Although that question is about embedding web browser engine with rendering stripped off . .. . Answer : A little history might help in your decision . When Apple was considering which engine to use in making Safari they looked at Gecko but decided to go with KHTML fork it and called it WebKit . Their reasons for doing this was that Gecko had tons of legacy cruft still leftover from Netscape and was far more complicated . KHTML WebKit was newer and thus had less legacy . It was also cleaner quicker and better documented . One of the goals of Firefox 3 was to clean up the codebase and simplify it . From what I ve heard they did do this but I don t know how it compares with current iterations of WebKit . It apparently wasn t enough for Google when they made Chrome and they have a significant stake in Firefox . See here http : arstechnica.com articles paedia mozilla-committed-to-gecko.ars 1 for more details . Comment : Firefox 3 was released on June 17th 2008 and by then Chrome had already been in development for 2 years if I recall correcly . I think it s safe to say that the restructuring Mozilla did for Firefox 3 had no relevance in Googles decission to go with Webkit .", "Question : I ve seen a few COM controls which wrap the Gecko rendering engine GeckoFX http : code.google.com p geckofx as well as the control shipped by Mozilla - mozctlx.dll http : stackoverflow.com questions 26147 is-it-possible-to-embed-gecko-or-webkit-in-a-cnet-win-form-just-like-a-webview .

Comment : Ideally it would run on windows so it could run on someone else s computer so the data can live on their system . That said by the time I showed them how to install python and whatever library I wind up using I might as well just do it on my laptop and carry a jump drive over . .. . Answer : You don t need Webkit to do that . All you need it an engine to run Javascript code so take a look at Gogole V8 http : code.google.com p v8 or Mozilla SpiderMonkey http : www.mozilla.org js spidermonkey . If you re prefer Python to build your crawler you may want to use PyV8 http : code.google.com p pyv8 as it provides all necessary bindings . Comment : Splitting tiny hairs : PyV8 appears to only have a version for 32-bit windows http : code.google.com p pyv8 downloads list . Also for others reading installing SpiderMonkey on Windows appears to be nontrivial but I found this article how to do it http : www.mailsend-online.com blog extending-spidermonkey-javascript-on-windows.html .

Actually both your PDFs take about the same time until being properly displayed by Adobe Reader on my computer . But while your bad-uc.pdf first shows the OCR ed text and then covers it with the scan the good-uc.pdf first seems to show a plain page and then covers it with the scan . The cause for this is that good-uc.pdf paints the OCR ed text in rendering mode 3 invisible while bad-uc.pdf paints it normally in rendering mode 0 fill outline with fill color black . As invisible painting may require less time than actual painting in black on white there might even be an objective difference between the rendering times but I think it mostly is subjective . Comment : Thank you very much mkl for the great information Do you know if there is any Linux tool can alter the rendering mode So I can ge tthe bad-uc.pdf to render in mode 3 invisible . Comment : I don t know such tools i merely have an idea how to implement such a tool . Comment : Thanks a lot sir That was a great hint . I have managed to wrote a simple script that inserts the rendering mode tags into appropriate places . However that script might only be useful to our application as all of our PDFs are generated by ABBYY and we have control over the PDF s format consistency to allow my script to insert tags in the correct places .

Answer : Your code is correct You ve run into an idiosyncrasy of Windows . The file you re reading is inside the C : Windows System32 directory . On 64-bit Windows if a 32-bit application attempts to access that directory it gets redirected https : msdn.microsoft.com en-us library windows desktop aa384187 28v vs.85 29.aspx to C : Windows SysWow64 . As there are cmd.exe files in both C : Windows System32 and C : Windows SysWow64 but they re different builds and so different hashes programs checking the hash of C : Windows System32 cmd.exe will give different results depending on whether they re 32-bit or 64-bit . You can see this for yourself by building your example program both 32-bit and 64-bit and observing that they give different answers . Comment : thanks very much dear .", "Question : null .. .

Answer : I m trying to encrypt text block with AES128 ECB mode to test resulted encryption decryption functionality I m using using ECB-AES123 test vectors from Recommendation for Block Cipher Modes of Operation : Methods and Techniques NIST Special Publication 800-38A 2001 Edition http : csrc.nist.gov publications nistpubs 800-38a sp800-38a.pdf . For example : .. . .. . For OpenSSL following code works perfectly : .. . .. . But at the same time I need implement same functionality with Microsoft s Crypto API . Following is code which should do it : .. . .. . But this code will produce different result . 1 . If Final will be TRUE as was shown above input data will have size 32 bytes which doesn t match expected value at all . According to MSDN it s OK since in this case one additional block of padding is appended to the data . 2 . If Final will be FALSE input data will have expected size 16 bytes but also wrong result . I have stuck with this case and I don t understand what I have missed . Is it possible to produce same result as OpenSSL which is expected according specs Why AES128 in ECB mode changes size of result In ECB mode it shouldn t do it Comment : Setting NoPadding or its equivalent will get rid of the second block . Best to check that your keys and IVs are byte-for-byte the same . OpenSSL and MS are likely to have different defaults so if you rely on system defaults you will get a mismatch . Wherever possible explicitly specify everything so you know they are the same in both systems . Comment : Yep I agree . I have thought about padding disabling . But the problem is that typically padding should be added when the last plain text block is short Sample from MSDN : if the block length is 64 bits and the last block contains only 40 bits then 24 bits of padding must be added to the last block . But in our case all blocks have same size - 16 bytes . Also don t found any possibility to disable padding for incoming data . Looks like it s default behavior . Comment : @AlexZeydel 1 I don t get your point . If you use PKCS 7 padding a 16 byte plaintext will map to a 32 byte ciphertext since it adds between 1 and 16 bytes of padding . It will automatically be removed when decrypting if you use PKCS 7 padding during decryption as well . If you don t want padding you need to disable it . 2 Why are you using an IV ECB doesn t support IVs . Comment : Also it s a little bit tricky to set the same default behavior for both OpenSSL and MS Crypto API libraries since we don t know what is default MS behavior . OpenSSL can be easily checked since all src are available . As for me the problem looks like I have missed something in configuration steps before call CryptoEnctypt Comment : @CodesInChaos 1 yep looks like pkcs 7 is default behavior for MS CryptoApi but at the same time we cannot disable it there . Also as far as I know AES cannot use for example pkcs 5 . 2 Why you have made such decision about IV . In ECB mode we don t need it at all.In my case I have just the key password 16 bytes plain data also 16 bytes and result which should be also 16 bytes", "Question : null .. . Answer : Hello there so I am having a very weird issue while trying to decrypt AES text that has been encrypted with AES using phpseclib . I RSA encrypt an AES key that I use to encrypt a message to the server . the server decrypt s the RSA encrypted AES key and uses it to decrypt the incoming message . also to encrypt the reply . I verify that the key is the same by exporting the AES key as a PLAINTEXTKEYBLOB . The problem comes when I go to decrypt the AES encrypted text from the server with WCAPI using the hKey HANDLE that was generated to encrypt the original message . CryptDecrypt only leaves me with junk . the Decryption does not produce the original message . I ve also verified that I am in fact decrypting the encrypted message and not some random buffer . Also before I attempt to decrypt this message I send an encrypted message that contains my public-key so that the server can encrypt the next AES key . This is successful . I am able to encrypt decrypt from C++ to PHP but not vice versa . Here is the PHP . Here is the C++ Comment : Ive tried using the AES hKey as a session key where by i encrypt the message with the same key used to decrypt the message . server-side . Ive verified the keys match both sever client-side but still no success . I just get garbage... .

If you aren t setting the IV anyway may as well specify ECB mode keeping in mind ECB is not very secure .

But that would only apply to the first block of the file . After that as the chaining kicks in the CBC mode would protect the other blocks .

That along with the first comment If you aren t setting the IV anyway may as well specify ECB mode which is also factually wrong when taken alone lead the uninitiated down an incorrect path of understanding . .. . Answer : Yes this suggests that you ve got the IV different on a given encrypt decrypt pair . The reason only the first block is corrupted is that CBC block errors only propagate to the next block and not further . You re either chaining from a previous operation if you re reusing the context across files or you re not initializing the context to the same value for both the encrypt and decrypt . Looking at your code you ve commented out CryptSetKeyParam ... . KP IV ... . meaning your AES context is likely having unknown data in the IV . A relatively common practice is always use 0 s for the IV but put a block of random salt at the beginning of the data . You then ignore the first block of the data when you re decrypting . It s only there to randomize the data . OR you could randomize the IV but send it prepended in plain text to the encrypted message . This is also very common . Or you could randomize the IV on encrypt put in a block of random data before the real message . Use any IV on decrypt and throw away that first block because it will be garbage . It s all pretty much the same result you end up transmitting 16 bytes as overhead but you should put some randomness into your message either through the IV or the first block to thwart short cut attacks .", "Question : Ok so I have 5 files I am encrypting .

My mistake . Sequential transform modification means matrix-multiplication from the right . So the last applied modification works first while transforming because transforming is matrix-multiplication from the left . .. . Answer : The order in PAffineTransform is related to the fact that each node in Piccol2D has an affine transform that defines a local coordinate system for that node . Usually to scale about a particular point you first translate the object so that the point is at the origin . You then perform the scaling and then the inverse of the original translation to move the fixed-point back to its original position . PNode has its own local coordinate system with origin at 0 0 . So when scaleAboutPoint is performed on a node the order defined in PAffineTransform makes sense .

Comment : Very useful thanks Just a quick reminder that if using javascript html5-canvas the context.setTransform function takes in the exact outputs of your function so this is a great tool for mapping images from one coordinate system to another when you have a triangle of points registered for each . .. . Answer : If I understand this correctly your triangles have the same size and angles so you should be able to tranform them so that they have at least one point in common . After this they should only differ in rotation or could be mirrored so you could f.e . get the angles between the triangle lines and try these for rotation and could mirror one of the triangles if none of the angles works .

Scaling could be done easily just divide the length of the lines this will also give you some information about corresponding lines of the triangles but shearing will be harder.. . .. . .. .

In the mean time you can use the more generic ProjectiveTransform .", "Question : null .. . Answer : I ve tracked a plane through an image sequence using OpenCV and produced a chain of 3x3 TRS homogenous transform matrices actually affine homographies but I m simplifying . I now want to smooth the motion over time to stabilize the movement of the plane . I don t want to just smooth out translation I also want to smooth away jerks in rotation and scale . My problem comes up when dealing with pivots . My first thought was to decompose each matrix into T R S translation rotation scale components and then filter each component with Gaussian convolution . I don t think this will work . The problem is that if you have a pure rotational movement about a pivot that does not lie at the origin then when decomposed as TRS both translation and rotation will need to vary in-synch over time . If I then smooth T and R separately odd things could happen because in this case the translation is not real translation but translation induced by the pivot . For example imagine the case where I want to smooth T very little and smooth rotation a lot - this will cause wobble because the linked variation of T and R together is responsible for the rotation about the pivot . In this particular example if I instead decomposed as SRT rather than TRS then there would be no problem . My second thought was that I could somehow figure out the pivots afterwards by looking at the sequence of transforms . I could assume the existence of pivots for rotation scale that are constant over the entire image sequence and then try to minimize via gradient descent the variation in the leftover translation component over the entire sequence . I m not sure this will work . In general I m not sure this is even a solvable problem .

They also discuss how to interpolate between 2 affine transforms but I don t see how to extend that to interpolate between a Gaussian weighted-average of affine transforms Comment : To expand on my previous comment I don t want to interpolate between the entire affine transform I want to do something like a Gaussian convolution of just the TRS values but leave shear perspective unchanged because changing shear perspective would introduce weird distortions .", "Question : From the nifti header its easy to get the affine matrix . However in the DICOM header there are lots of entries but its unclear to me which entries describe the transformation of which parameter to which new space . I have found a tutorial http : nipy.org nibabel dicom dicom orientation.html which is quite detailed but I cant find the entries they refer to . Also that tutorial is written for Python not Matlab . It lists these header entries : .. . .. . I cant find these if I load the header with dicominfo . Maybe they are vendor specific or maybe they are nested away somewhere in the struct . Also the Pixel Spacing they refer to consists of two values so I think their tutorial will only work for single slice transformations . More header entries about slice thickness and slicegap would be needed . Its also not easy to calculate the correct transformation for the z coordinates . Does anybody know how to find these entries or how to transform image coordinates to patient coordinates with other information from a DICOM header I use Matlab . Comment : Please motivate downvotes so I can improve the question thank you . .. . Answer : Ok so they were nested away in what might be a vendor specific entry of the struct . When loaded in Matlab the name of the nest was inf.PerFrameFunctionalGroupsSequence.Item X . then the framenumber and then some more nesting which was more straightforward self explanatory so I wont need to add it here . But search for the entries you need there . The slice spacing is called SpacingBetweenSlices or slice thickness in the single slice case the pixel spacing is called PixelSpacing and then there are ImagePositionPatient for the translation and ImageOrientationPatient for the rotation . Below is the code I wrote when following the steps from the nipy link below . What happens is you load the direction cosines http : en.wikipedia.org wiki Direction cosine in a rotation matrix to align the basis vectors and you load the the pixel spacing and slice spacing in a matrix to scale the basis vectors and you load the image position to translate the new coordinate system . Finding the directoin cosines for the z direction takes some calculations because dicom apparently was designed for 2d images . In the single slice case the z direction cosines is the unit vector orthogonal to the x and y direction cosines the cross product between the two and in the multi slice case you can calculate it from all the differences in the translations between the slcies . After this you still want to apply the transformation http : stackoverflow.com questions 27550846 interpolating-or-resampling-algorithm-in-matlab-for-transformed-3d-image-prefer which is also not immediately straightforward . This results in this affine formula : .. . .. . enter image description here http : i.stack.imgur.com mszuc.png .. . .. . So basically I followed this http : nipy.org nibabel dicom dicom orientation.html dicom-voxel-to-patient-coordinate-system-mapping tutorial . What was the biggest struggle was getting the Z direction and the translation correct . Also finding identifying and converting the correct entries was not straightforward for me . I do think my answer adds something to that tutorial though because it was pretty hard to find the entries they refer to and now I wrote some Matlab code getting the affine matrix from a DICOM header . Before using the found affine matrix you also might need to find the Z coordinates for all of your frames which might not be trivial if your dataset has more than four dimensions dicomread puts all higher dimensions in one big fourth dimension http : stackoverflow.com questions 21755906 dicom-dimensions-in-matlab-array-all-frames-end-up-in-last-dimension-of-array .. . .. . -Edit- Corrected Z direction and translation of the transformation", "Question : I am on a team making some image interpreting software . I have made a real world distance measuring system that is fairly accurate for a given plane 0.3 difference with real life but when i asked my senior coworker how i could make it real world accurate he told me that i needed to calculate the affine parameters . I asked for more detail but I m not sure he quite knew it either either way he didn t go into more detail with me . After talking to a few different people about it i am certain that it is what i need to be doing . I have tried reading a lot of articles on how affine transformations work but matrix math has always been a big weakness for me and its been far too long since my calculus 3 classes . Can someone help me understand how you calculate affine transformations with object oriented logic because all these articles i am finding go way over my head when they start including nabla and matrixes and such in their equations its greek to me . I can learn how to use those things im assuming i will need to but it all just seems very convoluted to me . Help in understanding this topic would be greatly appreciated . I don t know if it helps but i am programming in c and start with 6 measurements of the sides and diagonals of a quadrilateral that the user inputs on the image . Comment : Are you familiar with using 3x3 matrices to represent rotations in space IMO it would be good to understand this first as affine transformations are usually represented by 4x4 matrices and in addition to rotations also include translations and projections . Comment : I am not . I am familiar with the fact that it is done i just have zero understanding of how it works .. . Answer : I ll just give some general information since more information about your particular problem would be needed to give more specific advice . Also I won t go into details about matrix-multiplication or about how to construct a matrix representing a rotation etc since I m sure there will be a library in whatever language you re using ie C that takes care of these . 3x3 matrices and rotations in space .. . .. . In this case after choosing an origin and coordinate system we d represent points in space by 3-dimensional vectors eg 0 0 0 would represent the origin and 1 0 0 a point 1 unit from the origin in the positive x direction . Now imagine rotating everything 90 degrees around the y-axis . 1 0 0 would move to 0 0 -1 while 0 1 0 wouldn t move . It turns out there is a matrix representing this rotation namely .. . .. . This means that if you multiply this matrix by a vector you ll get the result-of rotating the vector eg multiplying by 1 0 0 gives 0 0 -1 and multiplying by 0 1 0 gives 0 1 0 . Your matrix library will have a function MultiplyMatrixVector or similar name to do this and a function RotationY or similar name to construct the matrix representing a rotation around the y-axis by a given angle . It will probably represent the matrix by an array of 9 numbers read from the rows of the matrix 0 0 1 0 1 0 -1 0 0 or perhaps read from the columns 0 0 -1 0 1 0 1 0 0 you ll find out which from the documentation or trial-and-error . One advantage of representing rotations by matrices is that if you want to do several rotations in sequence you can just multiply the corresponding matrices . Again your library will have a function like MultiplyMatrices to do this . Note that generally the result depends on the order of the rotations . Again check the library documentation to know which rotation happens first when you use MultiplyMatrices A B . In practice to answer a question like If I rotate 30 degrees around the y-axis then 60 degrees around the z-axis what happens to the point 2 3 4 you would do something like this : .. . .. . 4x4 matrices and affine transformations .. . .. . The next part seems strange but we ll see how it s useful later : we re going to represent points in space by 4-dimensional vectors . Given a point in 3D like 2 3 4 we can get a 4D vector by just tacking a 1 on the end ie 2 3 4 1 . Conversely a 4D vector x y z w represents the point x w y w z w in 3D . Note that 2 3 4 1 and 4 6 8 2 both represent the same point 2 3 4 in 3D . Now we ll use 4x4 matrices to represent transformations . We can use all the 3x3 rotation matrices discussed previously by fitting them into a 4x4 matrix in the following pattern : .. . .. . For example the y-axis rotation above is now represented by .. . .. . As before we use MultiplyMatrixVector to apply a transformation to a point and MultiplyMatrices to do transformations in sequence . Why are 4D vectors useful We can represent some new transformations . For example panning everything 1 unit in the direction of the x-axis a translation is represented by .. . .. . More importantly we can represent a projection . Imagine your eye is at the origin and you are looking through a viewport in the plane at z 1 . Each point in 3D projects to some point in the viewport plane . It can be computed by applying the matrix .. . .. . and then dropping the z coordinate . For example consider the point p 2 3 4 represented by the 4D vector 2 3 4 1 . Applying the matrix gives 2 3 1 4 representing the 3D point 2 4 3 4 1 4 . Dropping the z coordinate p projects to 2 4 3 4 in the plane . This simulates how a camera maps points in 3D space to points in a 2D image . The projection can be more simply described without matrices - it just sends x y z to x z y z . The advantage of using matrices is that it can be easily combined with other transformations . eg if the camera is not located at the origin or pointing in the z direction you can account for this by multiplying by some rotation and translation matrices again being careful to get them in the right order . Comment : That was very informative thank you so much . So how do you go about reversing from 2d to 3d assuming you have measurements parallel to the observed plane I figure you use the inverse matrix and give it a projection into a z coordinate through some common factor of how shrunken a given point is correct", "Question : I am trying to affine rotate matrix in Android based on iOS Code .. . .. . iOS has two functions CGAffineTransformMakeRotation and CGPointApplyAffineTransform used for calculation .. . .. .

The object can only be modified in scene by similarity transform in 2D space scaled rotated translated so I need to estimate 2x2 transform matrix instead of 3x3 homography matrix in 3D space . How can I achieve this in OpenCV .. . Answer : You can use find an affine transformation between the point sets using opencv this is slightly more general than the case you are describing known as a similarity transform as it describes shearing transformations of the shapes as well . It can be performed using the function getAffineTransform InputArray src InputArray dst . This takes 2 sets of three points and calculates an affine transform between them . Comment : This method is not robust it s not directly applicable to many pairs of points containing outliers . Perhaps I should implement RANSAC on top of it by myself . Comment : @lizarisk Yes I think you could do this yourself . Out of interest what are you using to match SIFT descriptors Comment : I m trying BFMatcher with L2 norm and cross-checking and FlannBasedMatcher . Comment : try estimateAffine3D function . Comment : Although the method getAffineTransform is not robust enough for your application if it is more than fast enough you can derive a more robust algorithm . For example you could call it with multiple triples of points . Each call returns a matrix . Expectation is that most of the matrices are similar to your expected result with some outliers . You can calculate an element-wise arithmetic average for a first more robust rough estimate . You can use this estimate to eliminate the outliers by calculating distance min sum of sign x square to your average and take the non-element-wise median .", "Question : Hi i am trying to create the affine transform that will allow me to transform a triangle into another one .

Comment : Very useful thanks Just a quick reminder that if using javascript html5-canvas the context.setTransform function takes in the exact outputs of your function so this is a great tool for mapping images from one coordinate system to another when you have a triangle of points registered for each . .. . Answer : I m going to assume you re talking about 2D here . An affine transformation matrix has 9 values in it : .. . .. . There are 3 input vertices x1 x2 and x3 which when transformed should become y1 y2 y3 . However since we re working in homogeneous coordinates applying A to x1 doesn t necessarily give y1 -- it gives a multiple of y1 . So we also have the unknown multipliers k1 k2 and k3 with the equations : .. . .. . Each of those is a vector so we really have 9 equations in 12 unknowns so the solution is going to be underconstrained . If we require that a7 0 a8 0 and a9 1 then the solution will be unique this choice is natural since it means if the input point is x y 1 then the output point will always have homogeneous coordinate 1 so the resulting transform is just a 2x2 transform plus a translation . Hence this reduces the equations to : .. . .. . So k1 k2 k3 1 . Plugging these in and converting to matrix form yields : .. . .. .

Thanks for your hint . Could you add a link-to the documentation of this folder", "Question : Culprits is the list of users who committed a change since the last non-broken build till now . The Jenkins Email-ext plugin is able to send an email to the culprits during a Post-Build action . I want to use the list of emails defined by Culprits in a python script build step inside of my Jenkins job . Can anyone suggest how I can do this .. . Answer : The culprits list comes from the SCM plugin in jenkins and includes all users who have committed since the last successful build . Ultimately the email-ext plugin is sourcing its list from scm and generating the email addresses based on the following heuristic https : wiki.jenkins-ci.org display JENKINS Email-ext+plugin .. . .. . The plugin will generate an email-address based on the committer s id and an appended default email suffix from Jenkins s global configuration page . For instance if a change was committed by someone with an id first.last and the default email suffix is @somewhere.com then an email will be sent to first.last@somewhere.com .. . .. . If your email addresses have some sort of pattern and they must do otherwise the email-ext plugin would not be generating the correct addresses then you can generate them yourself inside a groovy script eg : .. . .. . This example would convert a culprit like Adam Smith to adam.smith@mydomain.com But you could replace the call to getFullName with a call to getId and manipulate that however appropriate . eg : .. . .. . Which is the basic format that email-ext uses - You can get a full list of user properties from the documentation . http : javadoc.jenkins-ci.org hudson model User.html .. . .. . Now you have the list in a groovy script but how to make that list available to your python script That will come down to what you are used to doing . You could write the list to your workspace and read it from python or save the result to an environmental variable or even save it to a build parameter .

I want to include certain email addresses as bcc and am using the following convention when specifying email addresses : .. . .. . email1@domain1.com bcc : email2@domain2.com cc : email3@domain3.com .. . .. . The first and last emails get sent correctly . However the bcc email gets sent in the To section of the email with b prefixed to the address . So instead of email2@domain2.com it tries unsuccessfully to send an email to bemail2@domain2.com . I looked at the email-ext issue list related to bcc and cc and did not find anything similar to this . Therefore I am posting it here . Thanks in advance . .. . Answer : Handling bcc was added in this commit https : github.com jenkinsci email-ext-plugin commit 4aacabf9b9fa9be326ebc362519e2f5d1bbb43fb on Feb 24 2014 according to the changelog there was a related fix https : wiki.jenkins-ci.org display JENKINS Email-ext+plugin Email-extplugin-2.40.3 28May20 2C2015 29 released as part of 2.40.3 on May 20 2015 .

Answer : You don t need to write a plug-in the built-in attr module http : nose.readthedocs.org en latest plugins attrib.html is designed for this purpose .

You d probably want to just run all tests if you re considering writing a script that will modify that config file and re-run your nose tests .

Answer : nose2 does not have colored output built-in but a popular third-party plugin named green will color the output for you .

It works for me but I m still curious about how to do by dynamically generating a module . Here is the code to do it with a temporary file : .. . Answer : There are two ways to execute nose . There is a standalone program that comes with the distribution called nosetests . You can pass your file with the unittests in as an option : .. . .. . nosetests unittests.py .. . .. . Or specify a module : .. . .. . nosetests mymodule.test .. . .. . Or alternatively in your test module you can call the nose library and ask it to run by calling nose.main or nose.run in your program . Comment : This is for nose but I m using nose2 .

The package is called vimhdl and the coverage section of my unittest.cfg looks like this : .. . .. . With nose2 the result doesn t include all files from the package maybe because of Coverage.py warning : Module vimhdl was previously imported but not measured . message but I don t know how to fix it . Also when opening the HTML report for a given file statements such as import logging and modules doc strings are marked as not covered . On the other hand with nosetests the result include all files as expected . How do I configure nose2 coverage plugin to cover only a given module The source code is on github at https : github.com suoto vim-hdl tree unstable if it helps . Comment : I found a workaround that worked for a single test file by using the coverage.py API directly as show on coverage.py http : coverage.readthedocs.org en coverage-4.0.3 api coverage.html the-coverage-class docs . The problem is that it seems to work for only one file repeating it on a different test source file does not generate a report with combined results . .. . Answer : The simplest way to control coverage.py is to use it to run your tests : Comment : That worked perfectly thank you . I m still puzzled why using coverage plugin within nose2 doesn t works this way .", "Question : With unittest I can check if there were failed tests during test run like this : .. . .. . How to do the same with nose2 .. . Answer : Finally found an answer .", "Question : I m having trouble actually skipping a unit test from a Nose2 plugin . I am able to mark the test skipped and see the reason in the final result but the test still runs . This example code should basically skip any test as long as the plugin is active . If I call event.test.skipTest reason it actually raises the SkipTest exception like it should it s just that the exception isn t caught by the test runner it just raises inside of my startTest hook method . Any ideas .. . Answer : I don t think you can actually stop a test from running with the startTest hook . The nose2 docs http : nose2.readthedocs.org en release-0.3 dev writing plugins.html recipes suggest using either matchPath http : nose2.readthedocs.org en release-0.3 dev hook reference.html matchPath or getTestCaseNames http : nose2.readthedocs.org en release-0.3 dev hook reference.html getTestCaseNames to do this . Here s a working example using matchPath : .. . .. . The matchPath docs actually explictly explain how it can be used to stop tests from running : .. . .. . Plugins can use this hook to prevent python modules from being loaded by the test loader or force them to be loaded by the test loader . Set event.handled to True and return False to cause the loader to skip the module . Using this method will prevent the test case from ever being loaded . If you want the test to actually show up in the list as skipped rather than not have it show up in the list of tests at all you can do a little bit of hackery with the StartTestEvent : .. . .. . Here we replace the actual function the test is going to run with a dummy function that does nothing . That way when the test executes it no-ops and then reports that it was skipped . Comment : Yeah this was the best thing I could come up with too . To any future viewers you will want to make sure to patch the setUp and tearDown methods with the dummy function as well . Those would still execute which may be undesirable", "Question : I m running nose2 tests with the coverage plugin . I noticed that decorators class declarations and function definitions aren t being marked as covered even though the actual code underneath them is . I found this answer http : stackoverflow.com a 8637093 which suggests starting coverage earlier . How would I do this via nose2 I tried exporting NOSE WITH COVERAGE True but that didn t seem to do anything . Additional context : eventually we re hoping to plug these tests into Jenkins if that matters . ETA : adding a coverage section with always-on True to my nose2.cfg didn t work . .. . Answer : The fool-proof way to get coverage started earlier is to use coverage to run nose instead of using nose to run coverage . For example instead of : .. . .. . you can use : .. . .. . and then just leave out the nose coverage options from blah blah blah . Comment : @swizzard : You ll have to show exactly the command-line you used . Your problem is a common one and running nose inside coverage is the best solution . It will work for you . Comment : coverage run -m nose2 --plugin nose2.plugins.junitxml --junit-xml results in the non-test code being under-counted essentially reversing what s counted as covered .

Comment : Would a cookie work for you or do you need to store a larger volume of data Comment : Are the values stored in local-storage or server-side session .. . Answer : No that s not possible . sessionStorage lives on the client . If you want to access it on the server you will have to write javascript that reads the value puts it in a hidden-field so that it is sent to the server . Or javascript that will read the value from the storage and redirect to the server passing it as query-string parameter . There s absolutely no way for the server accessing directly this storage .

One way that I know is by going to the client s console and type localStorage.clear . .. . .. . I m building a web app that uses HTML-local-storage to replace PHP sessions and cookies . I have a web app that does the following : .. . .. . 1 . User requests a web page from the server .. . 2 . Server responses a page with JavaScript to remove client s local-storage data email and password The password is actually a GUID string . 3 . The JavaScript script then sends as a post-request with the email and password to the Server . The email and password variables could be empty if the user is new or may contain values if the user is a returning user . 4 . The server checks if user exists or doesn t exist . 5 . If user does not exist then server sends the login page .. . 6 . If user exists then server sends the requested page .. . 7 . Once the user is good to go every time the user requests any web-page from the web server two things happens : 1 Every time the user requests a page the request will contain the user s local-storage data email and password 2 Every time the user requests a page the server does a query to the database to check if user exists . My questions are : 1 What are the security issues 2 Is there are a better way I don t want to use Sessions or cookies . Comment : sounds like a lot of extra credential passing . look into tokens . localStorage itself is not bad . Comment : Why don t you want to use sessions or cookies They could handle those requirements just fine . Plus you wouldn t have the overhead of authenticating at every request . Comment : If you want to implement this securely you ll find yourself re-inventing sessions . Comment : I don t see how this question is too broad . It outlines the problem in detail asks clear and specific question and as a follow-on question asks for a full explanation of the answer . .. . Answer : I m building a web app that uses HTML-local-storage to replace PHP sessions and cookies . Local storage is a solution aimed at replacing neither . Local storage is for storing data client-side . Cookies are for identifying clients at the HTTP level . PHP sessions are meant for storing data server-side usually keyed by a cookie . The password is actually a GUID string . GUIDs are not really random . Depending on the algorithm used part of the GUID is the MAC address of the server generating . Next the timestamp is also used . You re left with not much entropy . See also : Are GUIDs good passwords http : stackoverflow.com q 804456 362536 .. . .. . The JavaScript script then sends as a post-request with the email and password to the Server . .. . .. . .. . Every time the user requests a page the request will contain the user s local-storage data email and password .. . .. . The thing with sending the password over the wire like this is is that you are giving attackers a predictable and frequent passing of the credentials . At a minimum this has to be done over a secure channel HTTPS . At that point though your security isn t terrible . The trick will be preventing others from accessing the local-storage . Be very aware of what scripts you include on your page . If you include some analytics or ad script for example it will have access to that local-storage data . And again use HTTPS to prevent people from fiddling with the page in-transit . A better way would be to use sessions with a rotating session ID . The password becomes the session ID and it changes for each request . This is much more secure than expecting a weak password from a user which rarely changes . The actual user s username and password are only sent over the wire once .", "Question : Web Storage Local and Session and IndexedDB are both client-side storage mechanisms .

Answer : Unfortunately I don t think the data flow can work the way you want it . In the Chromium WebKit implementation IDB stores data in levelDB files that you should not be able to access by design . So how do we get Java and JavaScript to play nice together That s a great question As I see it the only good way to transform Java data into IDB data is via the client-side . I ve got good IDB chops but my Android experience is non-production . From what I understand of it here s a proposed solution : .. . .. . collect data via native application views .. . write a string to a file in your sandbox with the data stored as a JSON blob or in an .html script attached to a JavaScript global .. . load a webview that can access a local URI like file : android asset blah.json and then run some IDB code to bulk insert it into IDB .. . use your IDB store to drive your web-based views .. . .. . So the answer to if and how the native app would access the browser s data store would be : try the opposite . Architect it to let your browser access your native app data store . Comment : Thanks for this . I can see that having a separate native app and offline web app probably won t work and I should use webviews within a native app instead . But in that case why use the IDB at all Won t it be better to do all the data-storage work in the native app Comment : Yes probably . There s only one good reason to use IDB and it s if you need indexed key-value stores at scale on the web .

I have looked into using cookies web-storage local-storage window.name and several other methods that other people have used but none actually seem secure and I am not able to use php . Is there a secure way to do this Comment : HTML5 local-storage http : www.html5rocks.com en features storage could do it . Comment : Depends what you call secure . localStorage and cookies are designed so that other websites can t access them regardless of any encryption . They just aren t allowed by the browser . But if you also want encryption you ll have to do it yourself . Comment : Encryption alone isn t the solution when you re dealing with login tokens . It also has to do with not allowing me to guess the value . What you store in the cookie localStorage should be a cryptographically secure-random number so that I can t easily guess the value of someone else s cookie . For example if we re just encrypting the password what if you and I have the same password If I update the cookie to use your username I might be able to login as you . That s why the value stored is also important not just how it is encrypted . Most Session management systems use a token as the storage . Comment : I had looked into local-storage but it is not secure enough for my purposes for example an XSS attack would be able to display what is stored . If the data I was storing was not confidential I would definitely consider using local-storage or cookies but after a lot of research I have found it s not recommended to store information such as passwords in local-storage or cookies . Comment : There is no client-storage that would be secure by the definition above . If your javascript can get to it so can malicious javascript injected into the page . .. . Answer : Well it depends on what you mean by Secure . By default for example PHP s built-in Session feature will use either a query-string or cookies . The same is true for ASP.NET s Session feature . These are used on millions of websites and I d say it is secure . The question is what are you storing in the cookie If you set a cookie like IsLoggedIn with a value of 1 that s not secure . However if you do like PHP ASP.NET do and store some random string ideally a cryptographically secure-random string which is validated server-side to a list of logged in random strings you re good . But that begs the question why aren t you just using PHP sessions to store this information See http : php.net manual en features.sessions.php Then you d store the IsLoggedIn in the session object which is stored server-side not client-side and you re secure . Comment : I have experience using php sessions and would definitely use them if I could . My issue is that I am limited by Squarespace as it does not support php .

In my view this is a big mistake from the developers as they hide the web pages javascript from the extension but allow it to see web-storage . Everywhere it is stated that the extension can only see the DOM but I do not think most people think that this also include web-storage So how can I secure a session key so it is away from reach of an extension Unable to encrypt it as I then just need to hide the key . The problem is that the session have to be valid for all pages of the site so I can not just keep it in javascript as it is refreshed on each page load . A cookie is in my view just as bad NB : Do not know if this is also a problem for other browsers .. . Answer : An extension given permission to access your page can do anything . A code injected as a script-tag from a content-script into the DOM will execute regardless of your CSP in the context of your page will full access to your JS context .

Answer : This is a great question Paul There s no circumvention of hostname restrictions and you re right to note this is by design .
