I just finished doing a clean test run across those 3 releases of Python with each of the 8 major config flags on/off (i.e. 48 runs of the test suite). As expected, almost all of the failures were in Python 3.x, and mostly related to unicode, where COPY_ON_ERROR generated failures when a unicode string was ...

Since this was a bit of a pain to track down, here's the process, on an Ubuntu Server 12.04 machine, to create many ALSA dummy devices:

$ cat /etc/modprobe.d/alsa-dummy.conf 
options snd-dummy enable=1,1,1,1,1,1,1,1,1,1,1,1 pcm_devs=4,4,4,4,4,4,4,4,4,4,4,4 fake_buffer=0,0,0,0,0,0,0,0,0,0,0,0
$ modprobe snd-dummy

That sample creates 48 dummy devices (on 12 cards), though that's likely more than you'll ever need.  The ...

So you have a Dell Ubuntu 14.04 Laptop and it is running way too hot. You can configure it to run at a reasonable level using i8kmon. As with anything heat related, be careful. If you miss-configure the machine you are likely to wind up with a fried machine!

You create a file called /etc/i8kmon.conf and put the ...

So the good news is that I've now got far more PyOpenGL output parameters automatically wrapped such that they can be passed in or automatically generated. That drops a *lot* of the manually maintained code. OpenGLContext works with the revisions, but the revision currently does *not* support non-contiguous input arrays (basically the cleanup included removing ...

Walter on PyOpenGL Users pointed me at the chromium "regal" tool, which has a table of constant definitions for output parameter sizings. I have a similar mechanism inside PyOpenGL's source code, so I parsed the table out of regal and used it to spot and plug gaps in the PyOpenGL table. The regal stuff is ...

I played with getting a py2exe executable created from PyOpenGL today, and it is very close to working.  The basics:

from distutils.core import setup
import py2exe
import glob, os
import OpenGL
data_files = [
    (
        os.path.join('OpenGL','DLLS'),
        glob.glob( os.path.join( os.path.dirname( OpenGL.__file__ ), 'DLLS', '*.*' ))
    ),
]

if __name__ == "__main__":
    setup(
        windows=['shader_test.py'],
        options={
            "py2exe": { ...

The second (and hopefully last) beta for PyOpenGL 3.1.0 is now available. These are the changes since Beta 1. If there's nothing critical showing up I'll do a final release in a few weeks.

• Generation fixes (lots of them) 
• GLES/GL-only extensions should now be generated only in the appropriate directories 
• Extensions which are multi-api will ...

pip's changes to not install pre-release software caught me up on my bad habit of just leaving alphas and betas of little-used packages that pass testing up as the "final" release. While I'm going to have to get that habit quashed, I've updated OpenGLContext-full in the meantime to pull the correct betas and have pushed ...

Went through my piled-up PyOpenGL email from the vacation and tried to address the various bugs and issues. Other than confirming a fix on hardware I don't have we should be pretty close to ready for a second beta. I regenerated the extensions based on the latest khronos api svn, so we should be pretty ...

So I wanted to work on a little web-toy that would let kids "hunt" for high frequency words  (basically vocabulary words that need to be immediately recognized) in a field of words. But as they don't necessarily know the words yet, it needs to be something that's read out audibly "Click on <blah>" and then I ...
