OpenGL just seems so messy (Providing "natural" semantics for a low-level API...)
Written by

Was just reading through the GLEWpy source-code for the ARB vertex-buffer-object extension. It's basically about the same level as the auto-generated SWIG, or ctypes interfaces. It should work fine, but it doesn't feel natural. Brian's interface looks a lot more natural to me, but it's also a lot more code.
I just have this nagging ...
It would be so much easier if I had hardware with these extensions... (Oh well, gives me an excuse ;) )

Spent a few hours reviewing and trying to integrate Brian's Vertex Buffer Object extension patch. It was made against the 2.0.1 release (my fault, I've been slow getting to it), so there was a bit of migration work to do. Problem is, the migration to SWIG 1.2.23 seems to have changed how the new vertex-pointer ...
No way to generate patches (SourceForge's anonymous CVS for "p" projects is down...)

Not a huge amount of PySNMP speedup for the day, wound up doing quite a lot of whole-application profiling, but hours of that only represents a few runs in total (it takes a long time to load 100MB of profile data in wxProfile). Discovered that, in the demo code, almost 33% of running time is ...
It may be worth it to rewrite wxProfile... (Well, actually wxProfile2, as that's what does hotshot loads)

It takes my (moderately beefy) machine 3 or 4 minutes to load a profile for a small HotShot profile run (e.g. the TwistedSNMP test suite). Although I try to do useful work while it's loading, a lot of the time is just wasted reading email, or news, or what have you.
It might be worthwhile ...
Optimising and re-optimising (Deja-vu for PySNMP hacking...)
Written by

Spent the whole day staring and poking at PySNMP. I think I see a way to speed the system up to something reasonable...
The basic problem is that any given final class, be it a simple integer holder or a full SNMP get message, is composed of about 20 mix-in and base classes, all of ...
A day on tickets and a night on Numpy (Need food though...)

Few more bug-fixes and enhancements to Cinemon today. Nothing stunning, a few new OIDs added to the collection, an annoying bug in the email-limiting code fixed, that kind of thing.
Spent the evening looking at Jelle's genetic algorithm code and then rewriting it using Numpy so it would both be easier to follow and more ...
Explanation of sorts for why conversion of Jelle's project didn't work (Tessellation was producing counter-clock-wise geometry...)
Written by

Snaking.
I converted Jelle's project to run in OpenGLContext, but when I did so, the rendering went all to heck, seemingly randomly losing triangular faces. Turns out it wasn't random, it was an artefact of the GLU tessellator wherein it was generating polygons which were in reverse order vertex-wise to those passed in as "solid".
Haven't ...
Think that's it for the week (Use up some of this week's overtime to get a jump on OpenGLContext etc.)
Written by

Was up at some ungodly hour this morning (though I steadfastly refused to answer the phone for whatever nut-case phoned me at 9 in the morning), so I think I'll use up an hour of this week's overtime (I have 7 hours extra just this week, which isn't a huge amount, but when you're not ...
Ah, the staccato glory of tickets closing (Or, two days of tweaking...)
Written by

Other than about 4 hours on the phone with D'Arcy, and about an hour tweaking the SIP pager demo, I've spent the last two (long!) days coding up feature requests and bug fixes gleaned on Tuesday. There's still a few left, but, save one, they're either involved (e.g. finding difficult to reproduce bugs), or likely ...
The days that make it all worthwhile (I'm obviously just hungry for validation of my life of poverty...)

Spent the day up at ACI hammering out an agreement on the 1.0 features and then interviewing Bryan and three of the technical staff regarding their use of Cinemon and what changes they'd like to see. They seem to like it overall, most changes proposed were either enhancements or minor cosmetic changes.
"It makes dealing ...
