'an online compiler/interpreter, and a simple collaboration tool. It's a pastebin that executes code for you. You paste your code, and codepad runs it and gives you a short URL you can use to share it.' supports C, C++, D, Haskell, Lua, OCaml, PHP, Perl, Python, Ruby, Scheme, and Tcl code; isolated by a geordi-based supervisor, in turn running inside a firewalled virt, in turn running inside a firewalled dom0. nice work!
