I should point out, I can work out it is printing 404, but what's all the other code doing? – Finglas Feb 4 '10 at 9:47

It's polyglot code - that is code that will compile unaltered in more than one language, all of which write 404 to stdout.

I can spot at least

  • C
  • Brainfuck
  • Multitude of scripting languages (Python, Perl, ...)

See Amusing 404 "Page Not Found" Images for Trilogy sites?

I think it was created on Meta : Amusing 404 "Page Not Found" Images for Trilogy sites? and is not a specific language, but multiple.

It looks like a mixture of obsfucated C and Brainfuck.

I know line three is Brainfuck. Go figure out what it does :-)
