Ubuntu 8.04 on high-end hardware

It's a Fujitsu-Siemens with LSI MegaRaid and fibre channel. I couldn't find the manuals for the server, so did a bit of intuitive guesswork.


Within 20 minutes I had massages 4 fast 2.5" drives into a RAID array with one hot spare, put Ubuntu 8.04 server on it, sitting inside an LVM Virtual space, installed a MySQL server and copied a large database over.


Then I pulled a drive out. The array reconfigured on the fly and rebuilt itself.


It just works!

Canon FS2710

Not that I was about to upgrade to Vista, or anything (the 2710, a film/slide scanner doesn't work on Vista) but the installation process, even on XP, was hard work. The ASPI layer had to be there, which meant a genuine "Adaptec" SCSI card, and it always reported itself as an unrecognised device.


I've just moved over to Ubuntu Gutsy for my main workstation setup. I spent a happy hour installing an Acer flatbed, which worked perfectly in xsane - indeed, even better than before on XP.


I put the SCSI card in. I plugged the FS2710 in. I downloaded vuescan from www.hamrick.com - and, lo and behold, it just worked. And the software is far better than Canon's own. I get real, archive quality scans

www.geogebra.org

One of few Java programs I've ever enjoyed using. It is seriously well designed to model geometry and algebra simultaneously - and ideal to use in the teaching classroom with maths students.

Recommended.
