I'm using python to interface a hardware usb sniffer device with the python API provided by the vendor and I'm trying to read (usb packets) from the device in a separate thread in an infinite loop (which works fine). The problem is that my main loop does not seem to ever get scheduled again (my read loop gets all the attention). The cod...
I'm rephrasing this question because it was either too uninteresting or too incomprehensible. :) The original question came about because I'm making the transation from Java to Groovy, but the example could apply equally when transitioning to any of the higher-level languages (Ruby, Python, Groovy). Java is easy to debug because there ...

Hello, I'm looking for a robust way to list the available serial (COM) ports on a Windows machine. There's this post about using WMI, but I would like something less .NET specific - I want to get the list of ports in a Python or a C++ program, without .NET. I currently know of two other approaches: Reading the information in the HARD...

I want to log how long something takes in real walltime. Currently I'm doing this: startTime = time.time() someSQLOrSomething() print "That took %.3f seconds" % (time.time() - startTime) But that will fail (produce incorrect results) if the time is adjusted while the SQL query (or whatever it is) is running. I don't want to just benc...
Hello there, I have a quite simple problem here. I need to communicate with a lot of hosts simultaneously, but I do not really need any synchronization because each request is pretty self sufficient. Because of that, I chose to work with asynchronous sockets, rather than spamming threads. Now I do have a little problem: The async stuf...
I recently asked this question in the pyglet-users group, but got response, so I'm trying here instead. I would like to extend Pyglet to be able to use an infra red input device supported by lirc. I've used pyLirc before ( http://pylirc.mccabe.nu/ ) with PyGame and I want to rewrite my application to use Pyglet instead. To see if a but...
Recently, I have become increasingly familiar with Django. I have a new project that I am working on that will be using Python for a desktop application. Is it possible to use the Django ORM in a desktop application? Or should I just go with something like SQLAlchemy? ...
I need a way to import the entire Python standard library into my program. While this may seems like a bad idea, I want to do this is so py2exe will package the entire standard library with my program, so my users could import from it in the shell that I give them. Is there an easy way to do this? Bonus points: I would prefer that thi...
I have an app written in python that presents some of its data in a tree view. By default, the tree view is a floaty white affair with little floaty triangles to expand the nodes. Is it possible to change this style to be more like a Windows explorer tree view? Specifically, I'd like to have vertical lines indicating parentage of the no...
I'm finding myself typing the following a lot (developing for Django, if that's relevant): if testVariable then: myVariable = testVariable else: # something else Alternatively, and more commonly (i.e. building up a parameters list) if 'query' in request.POST.keys() then: myVariable = request.POST['query'] else: # somethin...

I'm programming a simple pyS60 app, not really done anything with python or using multiple threads before so this is all a bit new to me. In order to keep the app open, I set an e32.Ao_lock to wait() after the body of the application is initialised, and then signal the lock on the exit_key_handler. One of the tasks the program may do is...

It seems like a simple question, but I've been looking for a couple of hours. I'm trying to process incoming JSON/Ajax requests with Django/Python. request.is_ajax() is True on the request, but I have no idea where the payload is with the JSON data request.POST.dir contains this ['__class__', '__cmp__', '__contains__', '__copy__', '_...
