The Ark of Neo

2012, end of the world.
You are in charge of an underground, self sustaining, computer lab. Internet is no more. Only wired networking is possible. You have only;

One enterprise server, 8CPU, 16GB RAM, 32TB of storage.
10 ATOM or APU computer terminals.

What software would you save to help/humanity, yourself?
OS, Applications, Development tools...

If the world has ended I see little point in using software, except maybe for entertainment if there is time.
