		BrandonM on April 7, 2011 \| parent \| context \| on: Using prime numbers to make better backgrounds This is the perfect Hacker News article.

		DarkShikari on April 7, 2011 \| parent \| context \| on: Chinese Infinite Magical Hard-Drive Depends... AVI: Index is at the end, so it might play fine in a tolerant enough player. MPEG-TS: Headerless. Will play fine in any player. MP4/MOV: Index is sometimes at the end; if so, it might play fine in a tolerant enough player. MKV: Has a header and index, usually at the start. Probably won't play. Ogg: Has a header, but is indexless; might play fine in a tolerant enough player. Probably not though, as both Vorbis and Theora (the only things Ogg supports that are ever used) both rely on custom Huffman tables in the headers.
		nadam on April 7, 2011 \| parent \| context \| on: Using prime numbers to make better backgrounds Cool, but these numbers don't have to be primes. They just have to be coprimes (like (8,9)). The least common multiple of two coprimes 'a' and 'b' is a*b. http://en.wikipedia.org/wiki/Coprime
