Yay, django 1.11 broken frozen/pyc migrations again

So somehow Django stopped being able to support .pyc files as migrations between our last builds with 1.11.lower and the current builds with 1.11.higher. Frozen environments use these to distribute just the .pyc (no source)... but somehow this got reverted because. But how did it get reverted in Django 1.11 (LTS) branch? Apparently it will ...

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:

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.

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 expect. 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 a ...

Review: Dell XPS 15 (9550) as a Linux Developer's Laptop

Update: the battery in this machine started swelling/exploding at 1.25 years Strongly recommend not buying one!

So I've now had a Dell XPS 15 9550 as my primary driver for approximately 9 months. I covered the (painful) setup process a bit when I first got it, so I won't repeat most of that here. Suffice ...
