The apparent rash of unprovoked police shootings in America | A few years ago if you remember birds apparently started committing mass suicide. Did birds just suddenly start flying into the ground or did one news outlet pick it up once, then another, then everyone forgot?

If everything is just ones and zeroes, how the hell does digital compression accomplish what it does? | A quick example. Say this is something you want to compress: 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 01010101 It's just 01 repeated 64 times . A compression algorithm would see that and insert a special code that means "Repea... |
