There are Python packages that are basically a PITA to get compiled into your virtualenv. The one I constantly hit when doing GStreamer, DBus, IBus, etc is gobject-introspection (a.k.a. gi). So, there's now a trivial package available:

source path-to-venv/bin/activate
pip install venvhpl
venv-hpl gi

So a few years ago, as I was working on a project called Listener that used PocketSphinx to allow dictation into the Eric IDE, I got some feedback suggesting that the only practical solution these days would be to use a neural network based dictation engine. That led me down a rabbit hole from which ...

So I've now spent the last day and a half playing with getting EGL offscreen rendering working on Linux. There are two major ways to do off-screen rendering with EGL and OpenGL. In the first, you use a pbuffer surface, that surface is basically a purpose-defined surface-type for off-screen backing of a renderer. When I ...

So having finally written down the thoughts on a carbon tax, that kept distracting me from actually working on Open Source, I finally got a bit of work done on Open Source on the last night of the vacation.

What I started work on was getting a sampling profiler format supported, and for that ...

I've pushed out the PyOpenGL 3.1.5 release. It has some (relatively minor) fixes for wgl and egl operations, and one for what looks like a change in numpy scalar handling in the latest numpy. Available on PyPI now.

So it has been a long time since I forced myself to boot into Windows to get support/development work done for the platform. Other than one hard-freeze where the machine updated its drivers, rebooted, and just stopped recognising the keyboard or trackpad, it pretty much just worked (turning it off and on again did, as ...

So it turns out that there's an extension for getting the DRM name for an EGL queried device that seems to work on Ubuntu 19.10. With that it should be relatively easy to target an off-screen render to a particular device. (The extension allows `eglQueryDeviceStringEXT` to respond to `EGL_DRM_DEVICE_FILE_EXT`). Happy New Year all.

So I finally pushed out the Python3/wxPython Pheonix compatible release of RunSnakeRun. The Python3 version has to run Python2 in order to load Python2 pstats dumps, and Meliae doesn't AFAIK support Python3 yet, so I expect I'll just drop support for it eventually. The code is now living on GitHub rather than Launchpad.

So as I work through all the OpenGLContext projects to get automatic (or near automatic) releasing, SimpleParse wound up failing on the 3.x branches with a weird xml test failure. But with Python 3.8 the C code just won't import at all. Seems there was a change in Python 3.8 where it does a load-time ...

So I just went ahead and pulled the trigger on getting PyOpenGL and PyOpenGL Accelerate 3.1.4 out the door. Really, there is little that has changed in PyOpenGL, save that I'm actually doing a final (non alpha/beta/rc) release. The last final release having been about 5.5 years ago if PyPI history is to be believed(!) ...
