You can take the much talked about ”6.001 - Structure and Interpretation of Computer Programs” course, from MIT, for free! Just combine the more than twenty hours of lecture on video with the free html textbook and start studying. Be kind, use the Torrents!

Any more, bit-twiddling is becoming a lost art form. But, if you’re applying for a job with me, I suggest you study some of these hacks. Furthermore, I recommend a great book called Hacker’s Delight. It’s a great book that any veteran, particularly fellow game programmers, should appreciate.

I finished today’s puzzle in 6:12.
Meanwhile, I was messing around with some really difficult puzzles in Susser Sudoku, a great freeware (Mac, Windows, and Linux) sudoku solver; and, holy hell. Puzzles that I was certain required backtracking (i.e. “guessing”) don’t. You really can figure them out. It seems like you can solve most puzzles with naked pairs, hidden pairs, intersections, and pinned numbers - but that’s just the tip of the iceberg.
On the USA Today puzzles I rarely need more than a single naked pair, and I never need to write out and track all of the possibilities. Easy.
Contrasting that are the puzzles in a book my sister-in-law got me called Second-Degree Black Belt Sudoku. I started a puzzle in this and quickly concluded that these weren’t “true” sudokus, but instead required guessing. Bottom line, I’m wrong. They’re just hard as hell. But that makes it fun!
