I have put in more than 100 inane entries into my Advogato diary by now.
Here is a nice weblog entry (try to ignore the awfully distracting background image) by James Gosling talking about the problems in "correctly" implementing sin() and other trigonometric functions in Java.
Yumpee had pointed me to some nice papers by some of his fellow Googlers a while ago. They make for some great reading. Try to at least read the papers on Google FS, MapReduce and Sawzall (in that order).
Some day, I hope to be able to decipher what Graydon says about programming languages.
