My youngest threw my (ancient) Motorola Milestone (Android 2.1 era phone) across the room onto a tile floor. Amazingly, the phone still worked, and I've been using it broken for a while now. I almost talked myself into just keeping it, as after all, a few minor cuts on the finger-tip from broken glass don't ...

So it turns out that the xml-generation branch for PyOpenGL was entirely broken. I'd cleaned up a module (OpenGL/constants.py) that shouldn't have been necessary any more, as the types and constants were moved into the OpenGL/raw/GL hierarchy.  Oops, turns out that everything imports that module.  Spent a ridiculous amount of time fixing that (i.e. making ...

The spammers finally convinced me that I have to restrict comments on the blog.  I was up to a few thousand blog-spams/day, enough that I was forgetting what I was going to blog about before I got through killing them all.  Comments are still open for 2 months, but trackback/pingbacks close within a few days.

Was stuck with no internet today, so the world gets a bit of work done on PyOpenGL...

So the branch in which PyOpenGL is generated directly from the Khronos API specification (xml) documents is almost workable. There are a lot of (internal) changes, particularly the OpenGL/raw APIs are pretty heavily rewritten, and I've landed a ...

The spec-xml-generated wrappers are getting pretty close, only the glGet constant handling is preventing the test_core suite from passing, and I want to rework that to use the spec's enum groupings to provide better coverage of those and be able to flag missing GET enum specs on generation.  Haven't started into GLX/EGL/WGL etc yet, just ...

So I finally (with some prompting) sat down to create a code-generator based on the Khronos specification xml documents (the things that khronos uses to generate the official OpenGL (GL and GLES), EGL, GLX, and WGL headers.  Originally I was trying to use Khronos own generator code, but in the end I just wound up ...

As some may remember, one of our products involves the user posting very large (multiple GB) files. Previously we've been using an nginx extension that does a direct-to-disk streaming decode during an upload, but that extension isn't available in newer nginx (which we'd like to have available in order to take advantage of HTTP Live ...

Apparently Kubuntu 13.10's version of the fglrx driver is now equivalent to the beta one I added to my 13.04 install to get it running, so I decided to do the upgrade. However, it kept failing with a cryptic error that it couldn't do the upgrade because I was either running a pre-release ubuntu (no) ...

Networking fun this week.

The big nasty that bit me was that a .bind( ('',port) ) on a multicast socket will get all packets sent to any local socket listening to that port, even if this socket has not registered membership in the group.  So if you have two capture processes, each trying to listen ...

I've lost track of how many SD cards I've lost now. No one I talk to seems to have these issues.

Today I lost another one, this one because it was physically broken, that is, the whole front corner of the card was broken off, so it no longer hits the little spring that indicates ...
