Lessons from Implementing from Scratch

So the last two days I was sprinting at PyCon CA. My original intent was to investigate tools for formalizing experiments with machine learning and reinforcement learning in particular. What we started with (and in the end, ended with) was a kind of "implement reinforcement (Deep Q) learning from scratch" project, where we tried to ...

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 ...

Trying out raw Debian on an old Laptop

So I was given an old Celeron M laptop (XP era, 500MB RAM) and decided to try Debian Stretch out on it. The default Debian netinst installer does NOT include proprietary wireless firmware packages... seriously? Practicality needs to beat purity there. The machine can't boot from USB, and my very last CD-R was used ...

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

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. It also is now Python 3 ready (i.e. one more package should now be out of the way to get OpenGLContext running under Python 3) and finally has ...

Fast.ai Setup for Google Colaboratory

I dropped into a study group today that was trying to work through the first Fast.ai course. It was the first day of the group, so most of the day was just spent getting everyone to the point where they could start working on the notebooks. I have my own setup available for Keras ...

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 ...
