In addition, your connection to the Judge (if you use the secure site) is encrypted using [http://www.openssl.org/ OpenSSL]. The Judge is administered through [http://www.openssh.com/ OpenSSH] and [http://freenx.berlios.de/ FreeNX]. Nice mathematical formulae on some problem descriptions and analysis pages would not be possible without [http://www.latex-project.org/ LaTeX] and [http://www.imagemagick.org/script/index.php ImageMagick]. The Judge hosts its own DNS using [http://www.isc.org/software/bind BIND], as well as its own mail server using [http://www.postfix.org/ Postfix] and [http://www.dovecot.org/ Dovecot].
