In general, it's a good idea to used signed ints whenever possible.

Here are the only 2 reasons I see for unsigned ints:
- matching hardware or wire spec
- You need the extra range afforded, and don't need negative numbers.

And the reasons for using signed integers otherwise:
- It prevents other overflow and comparison problems. Ie, fixes other dumb coding issues like "if (my_gold - your_gold > 0)" becomes a bug when the gold types are unsigned.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.

Working...
