traps and shells

UNIX has signals, various signals. When you’re working on shell scripts, you may need to intercept and deal with them. The syntax for intercepting signals is the trap action SIG1 … SIGN, where depending on your shell the SIG1…SIGN may be specified as an integer (bourne shell, i.e. raw sh), or symbolically as HUP, TERM (ksh, bash, zsh). Of course those of you using csh and tcsh should get a real shell 🙂.

Today’s bug

1120599 – Visor Prism Startup Crash
Based on the fact sheet from Palm one, we have the following details about a visor: it runs palmos 3.5.2, has a 16bit display, and when we start up pocketcity it crashes.
Well it doesn’t seem to happen with the developer roms I have, which makes things a bit difficult.

broken zim

Aargh! two of the chapters on disk 1 of the zim dvd collection are corrupt. I wonder what the returns policy on cdwow is? This is the second time I’ve received a bad dvd – the last one was the first black books series – the last section of the episode involving the subbuteo man, the chipper, the bottle of absinthe and the weather forecast is corrupt. I got a collection of the entire series recently so the loss of the one disk is kind of moot. However I want to see the end of ‘parent teacher night’ and the start of ‘walk of doom’ on dvd dammit!

Update: called them up – they’re sending out a replacement as we speak. Nice of them.
