Prime Nvidia can't find GLX (solved)

So the laptop (XPS 15 Kubuntu 18.04) has an nvidia 900 series mobile GPU. When I went to run the unit tests for PyOpenGL... almost entirely red. Because the X display had no GLX extension. To be clear, X was running, KDE Plasma (which normally uses GLX for rendering) was apparently using XRender silently ...

PyOpenGL 3.1.3b1 up on PyPI

So there's a beta release of PyOpenGL 3.1.3b1 up on PyPI. It needs testing on Mac and Win64/32 if possible. You should be able to install it with:

pip install "pyopengl==3.1.3b1" "pyopengl-accelerate==3.1.3b1"

The biggest change being that it should work on Python 3.7, and ...

TTFQuery 2.0.0b1 Up on PyPI

TTFQuery has a new release up. This release has a bunch of small breaking changes in it, specifically the command line demonstration tools now work differently.

PyOpenGL on Travis CI

So last night I finally got the PyOpenGL-on-github-to-TravisCI integration working. TravisCI is a CI service that has a free Open Source project integration. However, it doesn't support OpenGL on the xvfb-run tool out-of-the-box. The recipe to enable it is pretty simple, just install a bunch of packages and pass some args to the server ...

Dell Manages to top the Exploding Battery thing [Fixed]

[Update] Second level/RMA support just reversed their decision. I'm afraid I was rather impolite in my email response to their decision.

So the saga so far:

  • Dell laptop 3 months past 1 year warranty
  • Battery starts swelling/eploding while on trip in Italy
  • Turns out it is a "feature" of the XPS laptops ...

Docker on Centos7 host underwhelms

So one of the things I've been working on recently is creating a docker-based container to host a complex application for video processing that requires a lot of OS-level setup. I, of course, work on a number of Ubuntu 17.04 machines for development, and docker there has proven to be exactly what you ...

GStreamer Playback Captured mpeg.ts using Timestamps

The use case here is capturing a network input source (mpeg ts stream) and then using that capture for playback later. If you just use a filesrc your playback will run as fast as the machine can process it unless you've got an element in the pipeline that will limit the speed (such as ...
