What happens when you combine a $25/$35 computer, a major Linux distro's secondary arch effort, and a college that's deep into open source?

You get Fedora-ARM running on the Raspberry Pi at Seneca CDOT!

Here's a tiny video peek...

There's a lot of optimization still to be done (including X11) but look forward to a Raspberry Pi Fedora image (spin/remix), Fedora 15 for ARM, and the Raspberry Pi device itself all being available next month.

(In or near Toronto? There are three talks related to Fedora ARM and/or the Raspberry Pi at FSOSS next week).

The participants in the GNOME documentation hackfest led a great lunchtime talk on Friday, introducing GNOME 3 to about two dozen Senecans.

GNOME 3 embodies a complete re-design of the desktop. Clutter has been replaced with discoverable behaviours, visual cues, and generally streamlined operation. It's a bold experiment that has already attracted some detractors, but it was fascinating and enlightening to hear the environment explained by members of the community that created it. I'm looking forward to using GNOME 3 in the upcoming release of Fedora 15.

There were many who expressed an interest in attending but were unable to do so. Here are a couple of links:

• GNOME 3 site, with features, screenshots, and FAQ: http://www.gnome3.org/

For the next six days, CDOT is hosting some members of the of the GNOME documentation team for a documentation hackfest in preparation for the upcoming GNOME 3.0 release. On Friday we're holding an informal lunchtime talk to introduce the Seneca and Gnome communities -- and if you're in the greater Toronto area and are free, you're welcome to join us!

Today, the ATX power supply for the PandaStack I described in my last post is working happily. I have no idea what changed... which is a bit worrisome.

Our "PandaStack" of PandaBoard builders (shown here with 9 of the 15 builders installed) is now ready to run as part of the Fedora ARM build farm. However, I've run into a weird problem -- the ATX power supply I bought to power the boards works fine with 1-3 boards, but Something Bad happens when a fourth board is connected. It's not a capacity issue as far as I can see; it seems to be related to noise. Time to borrow a scope and take a close look at waveforms ... in the meantime, we'll power some of the boards with the ATX supply and some with stand-alone power bricks.

We're adding a group of dual-core, 1GHz, 1GB PanadaBoards to the Fedora-ARM build farm.  Paul Whalen and I hacked up the PandaBoard builder filesystem at FUDCon and I tested it with the farm on Thursday -- so far, it appears to build about twice as fast as the older GuruPlug builders. The PandaBoard's randomly-assigned-at-boot MAC addresses did force us to take a new approach to builder identity, though, because our previous approach of serving the identity via DHCP was no longer practical.

We ordered a total of 15 PandaBoards; 12 have arrived, and the others should be shipped shortly.Two are being set aside for testing, and we'll get the other ten building as soon as possible.

Our plan is to stack the boards on threaded rods, powered by an ATX power supply; the stack will be run on its side (with the boards oriented vertically) to aid in convection cooling. More photos to follow as we get this running! (Yes, that is a Powered by Fedora badge on there )
