The good news is that it's now a PowerEdge 2850 instead of a 2650. The bad news is that due to the magic of [BOB] and RAID, we've probably lost the contents of the HDDs. Murjan hosted progcomp: fortunately the code is in git, but trac and moinmoin are probably lost. Fun times. I've reinstalled Debian and Trac, and I'm working on MoinMoin. Wheel keys have been pushed and there's currently no user login (nor should there be until the end of progcomp). The root password is unchanged.

All 10.48.0.0/12 IP addresses can be accessed from the UCC network. Big thanks to Rob (jabawok) and trs80 for getting it going. This also means UCC traffic is now classified as FREE traffic from any WaFreenet AP in Perth or Kalgoorlie. A resources page will be made available soon.

It's currently available at: http://www.ucc.asn.au/infobase/minutes/minutes.xml The script that generates it runs as the planet ucc user on mooneye. It picks the fifteen most recently modified files with a .txt extension in /services/http/infobase/minutes and adds their contents to the feed. It will pick up files that have been modified after the fact and given the minutes shouldn't really change without committee approval, I feel this is a feature and not a bug. Haven't yet braved the crack that is Doctype grahame so it's not yet available as a published alternate on the minutes webpages. F. Ps. the code that generates this is available in git.
