Mathematics

MathOverflow, a nice site for graduate-level questions.
Paul's Online Notes, a useful Calculus resource (after reading the terms, find a course from the top menus)

Puzzles

Nurikabe: Daily moderate or harder puzzles. (I would love to see a Nurikabe puzzle that has a unique solution with the additional constraint that each possible Tetris piece is an island.)
NetWalk daily puzzles.

Chess Variants

Lots of (easy) applets: Ed Friedlander's site
Even more variants, plus some analysis: ChessVariants.org (I am an editor of this site.)
3+ dimensional analysis: CV Wikidot
A partial list of my favorites:

My own 4D game, and some thoughts: Chess-Basics
A mashing together of chess variant and deck-building game: For the Crown
