Reading Cryptonomicon right now, and it’s really very very good. I know I’m a little late on the Neal Stephenson train, but I’ve been going through his oevre lately.
How would I put it? William Gibson, but not as much obsession with mind altering drugs. Everything Cory Doctorow wants to be, without the quasi-fantasy leanings.
Of course, maybe I’m just biased towards authors that include perl code and scientific papers on the value of erections in their work.
