This is an online judge system with a very diverse and interesting
problems. A feature which is different than other systems I saw before
is the support of languages allowed. They support:
C (gcc 4.0.0-8)
C99 strict (gcc 4.0.0-8)
C++ (g++ 4.0.0-8)
Pascal (gpc v20030830)
Pascal (fpc 2.0.4)
Java (j2se jdk 5.0)
Nice (nicec 0.9.6)
JAR (j2se jdk 5.0)
C# (mcs 1.0.1)
Nemerle (ncc 0.2.1)
Smalltalk (gst 2.1.7)
Assembler (nasm 0.98.38)
Algol (a60 0.20a-4)
Fortran (g77 3.3.3)
ADA 95 (gnat 3.15p)
Bash (bash 2.05b-15)
Perl (perl 5.8.3)
Python (python 2.4)
Ruby (ruby 1.8.1)
Lua (lua 5.0.2)
Icon (iconc 9.4.2)
Pike (pike 7.4.35)
PHP (php 4.3.8-9)
Scheme (guile 1.6)
Scheme (qobi 0.9+0.10a)
Common Lisp (gcl 2.6.5)
Common Lisp (clisp 2.33.2)
Haskell (ghc 6.4.1)
Ocaml (ocaml 3.08.1)
Clips (clips 6.21)
Prolog (swipl 5.2.7)
Whitespace (wspace 0.3)
Brainf**k (bf2c)
Intercal (ick 0.24)
Text (pure text)
Would like to see Eu as one of the supported language there,
considering that Eu is now open source. Hm,, maybe someone who has
expertise in Eu can convince the author of the site to include Eu?

I have had some 'unusual' emails arrive that seemed to come from there too. I
wouldn't trust this site just yet.

Intrusion Detection Systems, Tripwire, Aide
and a proprietary Alpha system I'm writing in Euphoria.
Securing Linux is a lot easier on *nix than editing
M$-Win registry items to shut off DCOM's use of port 135
and various other services like tcp/ip Netbios helper..
I would recommend using nmap "its cross platform and will show
any open ports on your system..Also Ethereal will catch
incoming/outgoing packets in real time..
And, on *nix I would choose Fedora simply because it has the better
SELinux features constantly added for added security of course.
If you need to tighten a *nix box, I've been called the most paranoid.
and have a laundry list of how to protect your box.
example: forward port 113 into a non-used ip address on your router
and monitor ip's that try to use that ip. What this does is stealths
113 and port 80 even if port 80 is open to the world and a server is
behind it...
