I am trying to develop a python module as wrapper where I call another 3rd party module with its .main() and provide the required parameter which I need to get from command line in my module. I need few parameter for my module too.
I am using argparse to parse command line for calling module and my module. The calling parameter list is huge (more than 40) which are optional but may require anytime who will use my module. Currently I have declared few important parameters in my module to parse but I need to expand with all the parameter.
I thought of providing all the parameter in my module without declaring in add_argument. I tried with parse_known_args which also require declaration of all parameter is required.
Is there any way where I can pass on all parameter to calling module without declaring in my module? If its possible please let me know how it can be done.

This is a performance boost that avoids system calls and disk writes while the buffer is filling up.
Calling file.flush() will push the internal buffer to the operating system. You can additionally call fsync to request the operating system to save to disk.
Usually you can leave the operating system to do what it knows best, so calling flush is usually enough for most applications. The same is partially true for Python's internal buffer - it knows best in terms of performance, but you may require more frequent writes and be willing to pay the additional cost.

Upgrade uWSGI to recent stable version (as roberto suggested).
Use --thunder-lock option.
Now I'm running with 50 threads per process and all requests are distributed between processes equally. | 2 | 14 | 0 | 0 | I've installed Nginx + uWSGI + Django on a VDS with 3 CPU cores. uWSGI is configured for 6 processes and 5 threads per process. Now I want to tell uWSGI to use processes for load balancing until all processes are busy, and then to use threads if needed. It seems uWSGI prefer threads, and I have not found any config option to change this behaviour. First process takes over 100% CPU time, second one takes about 20%, and another processes are mostly not used.
Our site receives 40 r/s. Actually even having 3 processes without threads is anough to handle all requests usually. But request processing hangs from time to time for various reasons like locked shared resources, etc. In such cases we have -1 process. Users don't like to wait and click the link again and again. As a result all processes hangs and all users have to wait.
I'd add even more threads to make the server more robust. But the problem is probably python GIL. Threads wan't use all CPU cores. So multiple processes work much better for load balancing. But threads may help a lot in case of locked shared resources and i/o wait delays. A process may do much work while one of it's thread is locked.
I don't want to decrease time limits until there is no another solution. It is possible to solve this problem with threads in theory, and I don't want to show error messages to user or to make him waiting on every request until there is no another choice. | How to tell uWSGI to prefer processes to threads for load balancing | 1 | 1.2 | 1 | 0 | 0 | 9,291 |

For such a reason there is nothing like "a process executes it instead of a thread". Even without threads your process has 1 execution context (a thread). What i would investigate is why you get (perceived) poor performances when using multiple threads per process. Are you sure you are using a stable (with solid threading support) uWSGI release ? (1.4.x or 1.9.x)
Have you thought about dynamically spawning more processes when the server is overloaded ? Check the uWSGI cheaper modes, there are various algorithm available. Maybe one will fit your situation.
The GIL is not a problem for you, as from what you describe the problem is the lack of threads for managing new requests (even if from your numbers it looks you may have a too much heavy lock contention on something else) | 2 | 14 | 0 | 0 | I've installed Nginx + uWSGI + Django on a VDS with 3 CPU cores. uWSGI is configured for 6 processes and 5 threads per process.

There will then be row-head, row-tail, column-head, and column-tail nodes, but these are all accessible from the overall head and tail, so you don't need to keep track of them, and they're already part of the linked matrix, so they don't need to be part of a separate linked list.

For instance, a singly linked list with only a head pointer can be a stack (insert and remove at the head). If you add a tail pointer you can insert at either end, but only remove at the head (stack or queue). A doubly linked list can support insertion or deletion at either end (deque). If you try to implement an operation that your data structure is not designed for you incur an O(N) penalty.
So I would start with a single pointer to the (0,0) element and then start working on the operations your instructor asks for. You may find you need additional pointers, you may not. My guess would be that you will be fine with a single head pointer. | 2 | 0 | 1 | 0 | I know in a linked list there are a head node and a tail node.

I thought the app list might be exposed as a playlist, with each app as an IITFileOrCDTrack, but that doesn't seem to be the case. When I look at my phone as a source, it just lists media playlists (books, movies, etc.)

If you want to scroll the entire widget, you have to implement the GtkScrollable interface. Then, you add the widget to a GtkScrolledWindow. The scrolled window has the scrollbars, those GtkScrollbars are linked with GtkAdjustments which are passed to your custom widget through the GtkScrollable interface set_vadjustment and set_hadjustment.
If you just want to add a scrollbar and control its behaviour yourself, then you need to somehow add a GtkScrollbar in your widget, which means you will need to make it a container too.
The GtkScrollable approach is the following, first you implement vadjustment and hadjustment setters and getters, then when the GtkAdjustments are set, you set its lower and upper limits and the page size(how much of the widget is visible at once). After that, you connect their value-changed signal so you can refresh your widget when the scrollbars are dragged. A GtkScrollable doesn't get to check the scrollbars, only the adjustments that will be bound to the scrollbars. When drawing the widget you get the adjustments' value property in order to determine how much the scrollbars have shifted in the horizontal and vertical axes. | 1 | 0 | 0 | 0 | I'm working on a X-plotter like widget that plots incomming data live.
I already searched for an solution to realize a scrolling along the x-axis if the widget has to much values and so they don't fit.
I had the folling approaches to realize it:
derive from a widget that supports scrolling and child widgets and add my own widget while making it bigger and bigger during the live updates: -> Which parent do I need to use and how do I avoid to draw all the stuff that is currently not visible?
modify my widget in a way that it supports the scrollbars itself -> but how?
draw/handle my own scrollbars -> worstcase :(
I really searched the web for suggestions or examples, but there is nothing about how to "construct" custom controls in a good way (beyond drawing something) esp. in the case of interaction...

I am trying to write a python module that must take in arguments from the command prompt with sys.argv function calls. Rather than printing out the correct output when I enter E:\ ... \src>program.py arg1 arg2, all that happens is a new command line (E:\ ... \src>) is output and the Eclipse IDE window flashes orange without any code in my python module actually being executed. Also, if I close the Eclipse IDE and try to run program.py, it will just open Eclipse again and open my program in a new tab.
I'm confused as to why it is not working now when just last week it was working perfectly while testing another program that took in arguments from the command prompt by sys.argv function calls. My question for everyone is whether or not you are aware of any settings that may have been altered by updates, etc. that could cause this problem; or has anybody out there ever run into this problem and figured out how to resolve it?

This is bound to cause confusion, especially for novices. And it has caused exactly the kind of consuion it was bound to cause.
You've installed PySide into the /usr installation, so it ended up in /usr/lib/python2.7/dist-packages. If you run /usr/bin/python, that import PySide will probably work fine. (If not, see below.)
But the default thing called python and python2.7 on your PATH is the /usr/local installation, hence which python says /usr/local/bin/python, so it can't see PySide at all. So you need to get it installed for the other Python as well.
Unless you know that you need a second Python 2.7 in /usr/local for some reason, the simplest thing to do would be to scrap it. Don't uninstall it and reinstall it; just uninstall it. You've already got a Python 2.7 in /usr, and you don't need two of them.
If you really need to get PySide working with the second 2.7…
Since you still haven't explained how you've been installing PySide despite being asked repeatedly, I can't tell you exactly how to do that. But generally, the key is to make sure to use explicit paths for all Python programs (python itself, python-config, pip, easy_install, etc.) that you have to run. For example, if the docs or blog or voices in your head tell you to run easy_install at some step, run /usr/local/bin/easy_install instead. If there is no such program, then you need to install that. The fact that you already have /usr/bin/easy_install doesn't help—in fact, it hurts.
If you can get rid of the second Python, but that doesn't fix PySide yet, uninstall, rebuild, and reinstall PySide. Or, even simpler… PySide has pre-made, working binary Ubuntu packages for all of the major Python versions that have Ubuntu packages. Just install it that way. | 1 | 1 | 0 | 0 | I had PyQt4 running fine with python2 on Ubuntu 12.04. I then installed python-PySide. But the installation test would give me a module not found error. Then I installed python3-PySide and it works fine. So obviously something to do with my environment paths, but I'm not sure what I need to do. I'm guessing PySide is automatically checking if python3 exists and if it does then it'll use it regardless. I need PySide to work with python2.7 because of Qt4.8 compatibility issues. Any suggestions?

Would I have to use their storage facility (S3) because I guess if I have to run my script, I'm going to have to store it on the cloud in a place where the cluster instance has access to the files or do I upload my files somewhere else while working with EC2? If this is true is it possible for me to upload my entire directory which has all the contents of the files required by my application onto s3. Any guidance would be much appreciated. So I guess my question is do I have to use S3 to store my code in a place accessible by the cluster? If so is there an easy way to do it? Meaning I have only seen examples of creating buckets wherein one file can be transferred per bucket. Can you transfer an entire folder into a bucket?
If we don't require to use S3 then which other service should I use to give the cluster access to my scripts to be executed?

If you are still bound to write your own... Answering your specific questions:
With CD/DVD you first typically have to master the image (using a tool like mkisofs), then write image to the medium. There are tools that wrap both operations for you (genisofs I believe) but this is typically the process.
To verify the backup quality, you'll have to read back all written files (by mounting a newly written CD) and compare their checksums against those of the original files. In order to do incremental backups, you'll have to keep archives of checksums for each file you save (with backup date etc). | 2 | 3 | 0 | 0 | I have to archive a large amount of data off of CDs and DVDs, and I thought it was an interesting problem that people might have useful input on.

And, since the fastest CD drives are several dozen times slower than the slowest hard drives (and that's not even counting the speed hit for doing multiple reads on each bad sector for error correction), you want to get the data off the CD as soon as possible.
Also, of course, having an archive as a .iso file or similar means that, if you improve your software later, you can re-scan the filesystem without needing to dig out the CD again (which may have further degraded in storage).
Meanwhile, trying to recovering damaged CDs, and damaged filesystems, is a lot more complicated than you'd expect.
So, here's what I'd do:
Block-copy the discs directly to .iso files (whether in Python, or with dd), and log all the ones that fail.
Hash the .iso files, not the filesystems. If you really need to hash the filesystems, keep in mind that the common optimization of compression the data before hashing (that is, tar czf - | shasum instead of just tar cf - | shasum) usually slows things down, even for easily-compressable data—but you might as well test it both ways on a couple discs. If you need your verification to be legally useful you may have to use a timestamped signature provided by an online service, instead, in which case compressing probably will be worthwhile.
For each successful .iso file, mount it and use basic file copy operations (whether in Python, or with standard Unix tools), and again log all the ones that fail.
Get a free or commercial CD recovery tool like IsoBuster (not an endorsement, just the first one that came up in a search, although I have used it successfully before) and use it to manually recover all of the damaged discs.
You can do a lot of this work in parallel—when each block copy finishes, kick off the filesystem dump in the background while you're block-copying the next drive.
Finally, if you've got 1500 discs to recover, you might want to invest in a DVD jukebox or auto-loader. I'm guessing new ones are still pretty expensive, but there must be people out there selling older ones for a lot cheaper. (From a quick search online, the first thing that came up was $2500 new and $240 used…) | 2 | 3 | 0 | 0 | I have to archive a large amount of data off of CDs and DVDs, and I thought it was an interesting problem that people might have useful input on.

So the answer depends entirely upon your chosen solution (django-paypal or django-merchant or whatever). Read their documentation. Presumably there is some way to inspect the contents of a recently approved transaction. Cycle through the cart and enable a download of each.
Django-paypal, for example, has no interest of what is in the cart. It just fires a signal when a payment is successful, and passes back the transaction identifier. Your application must recall what the transaction was for.

I have looked at the django-paypal and django-merchent apps, but I don't know how to handle the multiple downloads. As far as I know, using these apps, after a successful purchase, the app sends a success signal, but doesn't tell me which books were ordered.

When you directly call dlopen() you have the freedom of specifying an absolute path to the library, which works fine. However, if you load a library which in turn needs to load another (as appears to be your situation), you've lost control of specifying where the library lives with its direct path.
There are environment variables that you could set before running your main program that tell the dynamic loader where to search for things. In general these are a bad idea (but you can read about them via the man dyld command on an OS X system).
When an OS X dynamic library is created, it's given an install name; this name is embedded within the binary and can be viewed with the otool command. otool -L mach-o_binary will list the dynamic library references for the mach-o binary you provide the file name to; this can be a primary executable or a dylib, for example.
When a dynamic library is statically linked into another executable (either a primary executable or another dylib), the expected location of where that dylib being linked will be found is based on the location written into it (either at the time it was built, or changes that have been applied afterwards). In your case, it seems that phys_services.so was statically linked against libphys-services.dylib. So to start, run otool -L phys_services.so to find the exact expectation of where the dylib will be.
The install_name_tool command can be used to change the expected location of a library. It can be run against the dylib before it gets statically linked against (in which case you have nothing left to do), or it can be run against the executable that loads it in order to rewrite those expectations. The command pattern for this is install_name_tool -change <old_path> <new_path> So for example, if otool -L phys_services.so shows you /usr/lib/libphys-services.dylib and you want to move the expectation as you posed in your question, you would do that with install_name_tool -change /usr/lib/libphys-services.dylib @rpath/lib/libphys-services.dylib phys_services.so.
The dyld man page (man dyld) will tell you how @rpath is used, as well as other macros @loader_path and @executable_path. | 1 | 12 | 0 | 0 | I am a newbie in this field. My laptop is Macbook air, Software: OS X 10.8.5 (12F45). I am running a code which gives me the following error:

installed Python on my machine (2.7)
installed steuptools
installed pip I can install items using pip on the command line, including
selenium In QC
I create a new VAPI-XP test
Choose PythonScript in the Wizard
Then click Finish (and do not go any further on the wizard)
Quality Center will then generate a skeleton script.
In the skeleton, Under TDOutput.Clear(), I type: TDOutput.Print("Hello
World")
The output window never clears and it never prints "Hello
World"
