Advogato: eek, almost 2 months without a diary entry. Sorry, I'll try to be more serious.
Hacking: trying to profile software. So far only gprof has been working for me (I couldn't get any copy of Corel's cprof, probably a Microsoft conspiration, and couldn't get oprofile to work on my kernel). Everyone told me gprof didn't work with multithreaded code, but after a little research I found some information on how to do it, and wrote a little "gprof with multithreaded applications HOWTO".
