Eliminating the last required OpenGL-ctypes extension (Still two optional ones...)
Written by

Snaking.
This morning I decided to eliminate the _strings.so C module from OpenGL-ctypes. This module had a single function which retrieved the data-pointer from a Python string structure. That was done mostly because of things like potentially having a different Python version or a different Python compilation flag resize the PyObject structure header and wanting to ...
Sysadmin Time Warp (Forgotten how much it consumes...)

Spent the whole day again on sysadmin work. Managed to get the VoIP sub-application installed and functioning, but I still don't have a fully functional ISP Billing System.
Discovered that the new (long promised) schema update for the ISP Billing System is going to cause dozens of (luckily fairly trivial) changes throughout the VoIP sub-application, ...
Long day of sysadmin-ing (Yay, a new server...)

Knight Errant.
Spent the whole day setting up our new development server (save for about 1/2 hour on billable work). I've got all of the secondary services set up, I'm just working on getting the legacy billing system built and set up now. Lot of dependencies in the tree, including multiple local-only data-types, a weird macro-expansion tool ...
Fixed one regression, another discovered (Don't fix unbroken things...)

The bug in the array handling for OpenGL-ctypes was due to my trying to be too clever. Oops. Finished running the OpenGL and OpenGLContext test suites. Biggest issues that surfaced were that the nurbs support has been broken somehow :( , and that the OpenGLContext mouse-handling code is accepting far too many events for processing, ...
Something got fixed on my machine (Probably by the gcc and glibc update)

Running the PyOpenGL GLUT demo "gears.py", which is basically identical to the standard glxgears program, today I get 1430fps on my workstation, (compared to about 1600 for glxgears today). This same machine was getting around 150fps last week (with either program). I'm guessing the complete system rebuild with gcc 4.x and glibc 2.4.x (which was ...
Apparently a regression crept in over the weekend (My lunch-break in testing...)

Spent the lunch break working on testing OpenGL-ctypes. Got through all of the PyOpenGL demos, but far more were failing than should have been. It appears I've introduced a bug in array handling at some point and didn't notice it. Grr. Worse, as I was testing in the OpenGLContext area I discovered a bug that ...
Manufacture a bit of time with a bit of sacrifice (OpenGL-ctypes instead of billables...)
Written by

in
Snaking.
Decided that I just had to get some work done on OpenGL-ctypes if it's going to come out any time reasonably soon after Python 2.5 final. Accordingly took the day off and worked solely on OpenGL-ctypes. Primary task today was to work on the documentation for developers and contributors. I've posted that (in-process) documentation to ...
OpenGL-ctypes time just doesn't materialise (Though my room is cleaner...)
Written by

in
Snaking.
I got a bit of hacking done on OpenGL-ctypes over the weekend, but not the 2+ days I'd hoped for. I started looking seriously at how to make the extension-writing process more automatic and clean. Also began working on the architectural overview and "how to contribute" documents.
We went for a party at Bryan's on ...
Never get too happy about the OS (It'll bite you...)
Written by

Tuxedo.
Okay, not really "bite" you, but you'll hit one of those moments where you have to rebuild the whole thing from scratch just to be sure that everything's going to work happily together. There's major updates to both glibc and gcc now marked stable on Gentoo. I'm going to do a rebuild world to make ...
What to do with vertex_buffer_objects? (Pushes itself deep into the rest of OpenGL)
Written by
on
in
Snaking.
A few fixes here and there in OpenGL-ctypes, allows a few more of the samples to run properly. Also did some preliminary testing with PyGame-ctypes (seems to work fine with OpenGL-ctypes). Then sat down to work on the ARB vertex_buffer_objects extension. The extension itself is fairly straightforward, but it's the side effects that make it ...
