Ogg for iTunes
If you’re using a Mac, you’re probably using iTunes to play music. As I discovered today, it doesn’t by default play Ogg Vorbis, but there’s this lovely Quicktime plugin which lets it do just that. iTunes, as usual, has some troubles importing lots of songs at once (haven’t they heard of threads?), but the songs play fine.
Also, if you’re using a unix and need to synchronize two directory trees, look at using rsync. Unlike what I thought, it doesn’t need a dedicated server. Instead it can run over a standard remote shell like SSH.
