Playing with the iPaq. Wrote some nice feature extraction code for FPU-less machines. Somewhat unsurprisingly, it's three times slower on my P3 laptop. (but 80 times faster on the iPaq)
Discovered a nasty bug in the iPaq audio driver, leading to a kernel oops. Predictably, select(2) was broken. Sent off patches. No reply. You'd think that a patch that changes a grand total of 4 lines, and fixes an oops, would get a bit of priority in people's mailboxes. You'd think wrong.
