Twitch Lightmaps and (the start of Shaders)

So I was feeling a bit burned out on programming this morning.  What's the solution to that, you ask?  3D graphics, obviously.

I pulled out Twitch (What's Twitch you ask? It's a very simple loader for .bsp maps).  I finished off the shader parser and added lightmap support.  At this point you can load ...

Toronto Python Meetup Hack Night Project

Hasan's project for the Hack Night was a log-file visualizer to be used with real-time-ish log parsing such that you could "waggle a mouse in this window and see the performance stats in this one" (he does video driver testing by day).  We decided to step that down to parsing a sample data-file (in this ...

New RunSnakeRun and SquareMap available

It has been rather a long time since the last release of RunSnakeRun, mostly because I don't actually find myself using it when I'm doing web development for the most part (just not as performance sensitive as 3D graphics I guess).  Since other people are using it, however, I suppose I should get a ...

Nginx upload module

Nginx has an upload module (in the nginx-extra package, not in the nginx-full one) that is very nice when you want to allow users to upload large files (think multi-GB video files).  The way it works is that you define a location to which posts may be made where the post may contain an upload. ...

Hyperloop Read-through

So somehow instead of working tonight I found myself reading through the Hyperloop plans from Elon Musk. Basically it's a very-low-pressure, but not true vacuum, steel tube held up on pylons from LA to San Francisco.  Linear accelerators (magnets) push cars through the tube by acting on aluminium blades on the bottom of the cars. ...

Laptop Presentation Fail Take 2

So yesterday we needed to have the participants at the PyCon/Mozilla Maker Party view their videos on the front projector, and the loaner laptops were not happy with the task (many of the projects had 2, sometimes 3 Youtube videos running at the same time in their mashups), so we plugged in my Laptop with ...

Public Service Announcement PyPI "wx" is not what you think...

It is not wxPython you are installing.  It's a "my first module" test package...

So how does one "claim" the top-level namespace module on PyPI when the namespace module is different from the name of the project.  Is there some mechanism to create a redirect from "wx" to "wxPython"?

Py_buffer underwhelms so far

I spent this evening getting the Py_buffer support in PyOpenGL worked through the codebase.  Originally I'd converted the numpy handler to use Py_buffer when in non-accelerated mode, but in the end it didn't provide much of anything other than the occasional "duh" moment where a piece of code assumed that you could treat an output ...

PyOpenGL Py_buffer Support Moving Forward

I've been getting the Py_buffer protocol based format handler for PyOpenGL implemented. The actual handler for buffer-providing types is pretty simple, and the numpy handler is now rewritten into a tiny subclass that just provides a "zeros" method and some "coerce to contiguous" code.  Not yet ready for prime time, and needs accelerator support still, ...

Packaging Ubuntu/Debian is not fun

So I wanted to get Eric4 running on my Ubuntu 13.04 laptop, no problem, the latest Eric4 is compatible, just download the Ubuntu package source, run bzr-merge-upstream and then debuild, right?

No, because Eric4 is a multi-file tar source, where the secondary files (translations) all have binary files that do not play well with the ...
