Dear All,
I proudly announce that the latest Online Judge plugin for Moodle 1.9.x begins to support all (I wish) Linux distributions with its sandbox. At least I tested it on Debian 5/6 and CentOS 5.5, and all are well.
Additionally, it begins to support 64 bit kernel. But all submissions from students will still be compiled & judged in a 32 bit environment.
It is kind for you to follow me or onlinejudge on
github.com to track updates. Thank you!
