This is a NOT gate done in minesweeter. the position of x and x' was switched.

This is apparently an AND gate. Some guy showed how you can simulate arbitrary circuits in minesweeper. Therefore he showed that solving minesweeper is equivalent to solving random AND, OR, NOT circuits. Apparently that problem is NP hard, so so is minesweeper! Who knew? That is cool as hell. It was sitting under my nose all those hours I played minesweeper and I never thought of it.

Someone's finally written a really good minesweeper page, too.

Sounds like a cult doesn't it?

Russia detected a US nuke launch in the 80s but he knew it was an error and didn't nuke us back.

Jesus.

Black- traditional characters. Red- what they were simplified to. I've looked for a big list of all the simplified chinese characters and what they used to be for a long time and never found one.
