Minor tweak to the kernel a bad idea (ztdummy non-functional, whole system gone for a bit...)
Written by

Tuxedo.
Woke up this morning to try the results of last night's last kernel recompile. I wasn't able to get zaptel running, and have been noticing that the system clock is going wildly out of sync (despite ntpd running), so I turned off the preemptive kernel switch. Oops. Every loadable kernel module became non-functional. Rebuilding the ...
Housekeeping is dangerous (Accidentally blow away my only working kernel's source directory...)
Written by

Tuxedo.
I ran out of disk space on my "old" drive (which is where my home directory and all non-multimedia files go), so I went through and killed off the various system directories from my old Linux install (I run from the new disk now). Unfortunately, I didn't remember that /usr/src contained the last working Kernel ...

Egads they're getting closer!
Save me gentle lady
From the murd'rous horde
Intent upon my words
I've so few left at this late hour
I must from random books implore
I scrape a few quick quips together
That holds them for a day
I leave a bit of rhyme
Sitting on their path
Hoping that ...
Why no productive output today (I need home for a rest...)
Written by

Vindaloo.
Out rather late yesterday (or this morning, I suppose). Leigh and I hit a trance club after Simon's party. Got home around 5am. Despite the lack of sleep, however, I triumphed 3 games to 1 against grams. However, I haven't been able to get to sleep for a nap yet (despite trying all afternoon). Too ...
Refined and Abundant Depth (First of the rest of the chapter...)
Written by

Design Theory.
The chapter on depth is really very long. The introduction to this section is a little to strong when read without that context, the division outlined here is one of many aspects of depth that gets discussed; you don't need to point out that there are others just as important:
For the purposes of designers, ...
How We Perceive Depth (Section after the introduction from yesterday...)
Written by
on
in
Design Theory.
This is the section just after the introduction. I've edited the introduction slightly (added a few paragraphs of clarification), but it's still basically the same. The section here deals with the question of how we perceive (detect) depth in our environment:
Human beings generally do not know everything about the environments they inhabit. We also ...
Rewritten Intro to Depth (Probably need another rewrite eventually...)
Written by

in
Design Theory.
I really want to try teaching this to people. It's so difficult to judge whether I'm going way too fast, or way too slow without some idea of what people can process (and what they already know).
Anyway, on a lark, here's the introduction to the section on Depth, this is now the third rewrite ...
Nurbs working in OpenGL-ctypes (Should have been writing...)
Written by
on
in
Snaking.
Wasn't really in the mood to write this afternoon, so I spent a few hours on OpenGL-ctypes. The nurbs support is pretty much finished, all of the tests I have work fine, including the callback test that didn't work under PyOpenGL. There's still problems where the slowdown on NURBS rendering winds up completely k-o-ing the ...
