Recently I re-read Rick Cook's Wizard's Bane and The Wizardry Compiled. I strongly recommend that series to anyone who wishes to be a serious developer.
And I realized that I'd been missing out on a lot of fun lately. Ruby's become so dry and boring, it isn't funny. I really miss the days of having a function named corned_beef which uses such wondrous numbers as 65353. And stack based programming really is da-bomb! I remember all of the fun I used to have with it and have realized it's time to go back to it.
