An animated GIF of the degradation of the block agar in Conway's game of life. The "camera" pans diagonally up and to the left at the same rate (3c/4) as the agar degrades. It's four generations per frame, which keeps the untouched blocks in the same...

One thing we can do in our dreams, easily, is for something or someone to be simultaneously two or more things at once. We cannot observe this in the real world, constrained by Maxwell's Laws of Electromagnetism (not even quantum superposition can...

Lossless H.264, e.g., x264 -q 0, is interesting as it invites a contest, compress a video as much as possible (I suspect even lossless encoding has degrees of freedom) while still being decodable by a standard H.264 decoder. Does winning help? Simply...

In order to make chess more accessible and interesting to spectate, the two players, probably placed in separate rooms with their own analysis boards, give live commentary about what they are thinking during the game as they play it, which is relayed...

A simpler implementation of the POSIX cksum program, calculating CRC32 big-endian, not using a lookup table. This is slower, but may be useful pedagogically. #include typedef unsigned int U32; const U32 polynomial=0x04C11DB7; void update_crc(U32...
