A better class of nightmare (Simple, direct, with inventions bonus...)

Apparently the movie last night really affected me. Night was peppered with dreams of fighting to be respected, fighting to survive, etceteras. Of the inventions I can remember, one was a monitor for store shelves that simply records when someone breaks the plane, the other is an old invention that was getting field-tested (well, used) ...

Why am I home on a Saturday night? (This is just pitiful...)

I keep thinking I'll sit down to work on PyOpenGL and having waves of ennui (can ennui form a wave? more of a sluggish oil-slicked wash than a wave, I guess...) wash away the desire. So, I watched "Always Outnumbered", which was perfect, because I've recently been getting a bad string of movies where they ...

Wow, a whole day on graphics (I'm so out of practice...)

One of the interesting things about design is that theory tends to be too slow as a mechanism for accomplishing it in the real world. While you could work everything out from first principles every time you wanted to place a piece of text on a sheet of paper, you'd get out-competed by the guy ...

Run Snake Run (A Python hotshot profile loading/display GUI)

Well, as mentioned earlier (yesterday), it takes far too long to load the HotShot profiler dumps. So, I wrote my own little loader/viewer package. It processes about 70,000 records/second, which lets it load a profile fairly quickly, but it's not blazingly fast by any means.

What makes it useful/cool is that it loads the dump ...

Profile first, then optimise (Surprising what you find with actual measurements...)

Biggest event of the day was discovering that 30% of total work in the system was being done in a __cmp__ method that was doing the equivalent of "if x is y" when everything was said and done. It appears, in the end, to have been the ultimate source of the slowdowns that I've spent ...

Wasn't I supposed to stop working back then (Look ma, hour-per-day discipline falling apart...)

Wanted to add some debugging code to see if I could catch some bugs during the evening's operation... turned into rather a lot of bug-fixing and minor feature implementation work that bring's the day's total to some entirely improper number of hours (sorry hands). I have to stop now or I won't be able to ...

A day of iconic splendour (Mmm graphics!)

Today was spent mostly cleaning up and extending the set of icons available in Cinemon 2.0. Nothing hugely challenging there; create a mechanism to allow for easily registering icon correspondence and another for defining an icon, then plough through and either assign or create-and-assign and icon for each major group-type in the system.

The impact ...

That day was way too long ("Finish the (major) feature" isn't a good plan for a day...)

For some reason (likely lack of sleep and exercise) I'm extremely tense today. My shoulders and upper arms are just masses of knots, which messes up my hands as I type. Did a huge amount of work on 2.0 today, as well as a bunch of administrative stuff for the 1.0 launch (18 days and ...

Sleep eludes me (Probably just need more exercise)

Haven't really slept well all weekend. Today was just a write-off, didn't sleep well last night and couldn't stay up for more than an hour at a time all day. Still kinda knackered. Only work I did all day was confirming that the wrapper code for the ctypes rewrite of OpenGL can handle the common ...
