Continuation Passing Style
So I'm reading Daume's YAHT - quite excellent by the way - and treading along just merrily until the section on continuation passing style (CPS):
cfold' f z [] = z
cfold' f z (x:xs) = f x z (\y -> cfold' f y xs)
cfold f z l = cfold' (\x t g -> f x (g t)) z l
This ... makes ... my brain ... hurt ( Read more... ) -
Number Theory
Aren't positive integers the damn'dest things? I just noticed today the sum over (1,2,3,4,5,6,7,8,9,10,9,8,7,6,5,4,3,2,1) was 100. And so I tried for (1,2,3,4,5,4,3,2,1) and alas the sum was 25. So here's my proof by MI for the "Mirrored Square" (I'm sure there's some official term for this numerical phenomenon buried in the number theory ( Read more... ) -
Sound in Firefox on Ubuntu Dapper
Just some knowledge I've gleened from the forums:
$ sudo apt-get install alsa-oss

$ sudo ln -s /usr/lib/libesd.so.0 /usr/lib/libesd.so.1
$ sudo mkdir -p /tmp/.esd
$ sudo touch /tmp/.esd/socket

So I've brewed up some simple experiments and was amazed to see that it just freaking works. Starting with a simple java class:

Python Decorators
Up until now, the easy way to write Python 2.4 function decorators that takes arguments before the decoratorated function has been a complete mystery to me. Writing a decorator that only takes its wrapped function as the first agument is pretty straight-forward. Alas, just a function that wraps another. Take for example, a function that ( Read more... ) -
WPA on Kanotix Linux 2.6.14
Finally got wpa encryption working on my laptop ... after lots of pain. It all boiled down to using generic driver (wext) instead of specific ipw2100/2200 (ipw) which was giving me nasty ioctl errors. Here's my kernel details:
