Books: Arthur Clarke, William Gibson, Kurt Vonnegut. I read a fair
amount of manga/comics, where I tend to prefer anything that you
wouldn't stereotypically associate with comic books.
Movies: A really don't watch a lot of movies. I didn't even have a
working DVD player until 2009. However, my go-to answers are
usually The Big Lebowski, Being John Malkovich, and Wings Of
TV: Breaking Bad, Hannibal, Louie, Stewart/Colbert.
Music: As a programmer, I'm usually listening to music about 6-8
hours a day, as it's a good way to break up the monotony, and to
keep people from bothering me. I listen to everything that I can
get my hands on at least once, but I make no promises about
listening to anything a second time. Personal favorites include
Beulah, Death Cab For Cutie, Elliott Smith, The Dismemberment Plan,
Blue Scholars, The Impossibles, Eve 6, Cake, The Mountain Goats,
Toadies, Thermals, They Might Be Giants, Why, The Streets, The
Tragically Hip, Pavement, Why? and Built To Spill.
