This Adobe's first offical linux release. A press release and the release notes have more information on new features.
UTS (formerly CIS) has installed MacConnect wireless in Hamilton Hall. Our temporary AirPort network (called 'math') will be removed on July 1st, 2005. Unlike the 'math' network, MacConnect is available to anyone with a MacId account (i.e. faculty, staff, graduate students and undergraduates); this is the same network which is available in the libraries, the student centre, and a growing list of other buildings.
I emphasize that you will need a MacId and VPN software to use the MacConnect wireless; see the MacConnect web site for more information.
The laptop/wireless section of the computing-resources web site will be updated in the next week or so.

There were problems sending mail via mathserv late Tuesday night after the system logs filled the main disk with warning messages. The source of the problem is being investigated and we have a work-around in place at about 8:00 am Wednesday.
This is most likely fallout from the disk crash on Monday.

OpenOffice isn't starting up on the msprime stations; I don't yet know why. A simple reinstallation is failing, too.
For now, please use gnumeric to open Excel or OpenOffice Calc spreadsheets.
Abiword will be available for Word and OpenOffice Write documents later on this evening.
Abiword now available; type abiword from a command prompt or Alt-F2.
Mathserv crashed at 1:02 pm on Monday, April 11th. It was back up again at 1:15 am with no data loss.
Most msprime workstations are picking up where they left off, though some may require a reboot.
The cause of the crash was a disk failure on one of the two RAID 5 arrays. "Aren't RAID 5 arrays supposed to be able to handle a single disk failure?" you ask. Yes; yes they are. But this is the second time since January that this server has failed to do so. I think that I have identified and solved a hardware problem that could have precipitated both this crash and the one in March.
Note that the department web site (including course pages) were only down from 1:00 pm to ca. 2:30 pm. I used the 2:00 am backup copy to bring the sites up on our backup server.
Plans were underway to reduce the likelihood of this sort of failure as well as the downtime should it happen anyhow; I am accelerating the project.
