books

i've got holidays for the next couple months and i've got no social life or off-line friends to speak of.
what are some good text books i can read during this time?
any subject is fine really, as long as it's somehow related to computers.
and by 'good' i mean detailed and thorough, not fun to read.

1 PPU and 6 SPEs is a really interesting platform to develop for. It's fun even if it's a totally neutered development environment and you have no access to the RSX and you're missing 2 SPEs.
