local book about python and unix - i used python around 2004 and beat the courses assignments ('beating the avg' reminds me of those days) ... later pg's great hacker on slashdot and then lisp - settled with newlisp now
iBookG4 exposed me to unix, designs, hardwares and most importantly, woz and jobs ... later my ibook was broken. I am very happy with OpenBSD now
chemistry (and later internet recipes): now i bath using soda ash and citric acid at very low conc - eliminate the need to restore soap and shampoo (great time and $ saving for me) ... i also make my own fertilizer for aquarium use
