Come and Speak at FSOSS 2010 Wed, Jul 21. 2010
The 9th Annual Free Software and Open Source Symposium (FSOSS, "eff-sauce") is coming up on October 28th and 29th, here at Seneca College in Toronto. This is a great event with a wide-ranging, eclectic mix of workshops and presentations.
I've been involved in planning FSOSS for the past few years, but stepped back a bit to catch my breath this year. Mary Lynn Manton has stepped up to the task of chairing this year's event with Rose Saliba, who is co-chairing for her third year.
FSOSS is still looking for interesting workshops and presentations on a variety of open source topics. If you're working with open source in any way, this could be a great opportunity -- please check out http://fsoss.ca and submit a presentation proposal right away!

Sugar on a Stick - Activities Thu, Jun 17. 2010
Sugar on a Stick is a project which aims to create a live learning environment on a USB stick. This environment is a Fedora spin hosting the Sugar environment (the learning software original created as part of the OLPC project).
In previous versions of SoaS, the activities were not thoroughly screened before inclusion in the Spin, and so the SoaS Activity Criteria were introduced. I've been working with some other POSSE RIT participants to try and get three activities - Abacus, Maze, and Memorize - to the point of meeting the criteria. It's been a frustrating experience, but we've made some progress:
- Performed a package review (not passed, but close) of Peter Robinson's sugar-abacus package in Fedora
- Created a basic page for recording smoke test results
- Filed a bug against the sugar-maze package in Fedora (apparently missing an essential .py file)
- This activity meets most of the criteria, but we weren't able to save to the journal (know issue) and could not confirm that collaboration works (might have been our Sugar configuration or networking)
Seneca and the Fedora ARM Secondary Architecture Thu, Apr 22. 2010
ARM processors power the digital mobile age. Billions are produced per year, ending up in the majority of cellphones as well as in e-book readers, plug computers, the OLPC XO 1.75, tablets, netbooks, intelligent RJ-45 network jacks, and even microSD cards.
The Fedora ARM Secondary Architecture project has done a great job of porting Fedora releases to ARM. To assist this initiative, this semester's Software Build and Release course at Seneca (SBR600) put together a new Koji build farm for the ARM architecture in preparation for using koji-shadow to follow the primary architectures. It's been a fascinating and challenging project -- working with cross-compilers, emulators, and hardware with much smaller configurations than standard PCs. A large amount of effort was spent benchmarking various configurations to determine optimal memory and storage arrangements and to compare emulated vs. hardware ARM performance to guide the configuration of the build farm.
So now we're at the end of the semester. Where do things stand?
- We have a working Koji build system, with two hardware builders plus emulated (VM) builders
- Since we're at the end of the semester, things will be quiet for the next week and a half, but then we've hired a graduate to work on this full-time (intros coming up shortly )
What's next? In May-June we expect to:
Running Fedora-ARM in emulation under virsh Thu, Mar 4. 2010
The Fedora qemu-system-arm package provides pretty good ARM processor emulation, which can be used to run the Fedora ARM secondary architechture. This is an easy way to get started working with ARM -- for example, while waiting for your plugcomputer, beagleboard, or OLPC XO 1.75 to arrive
The previous wiki notes on using ARM with QEMU didn't cover using qemu-system-arm under libvirt management. This meant that you couldn't easily take advantage of libvirt benefits such as automatic network setup (with DHCP and NAT), the virt-manager GUI tool, guest autostart, or disconnection/reconnection to the console.
I've updated https://fedoraproject.org/wiki/Architectures/ARM/HowToQemu to include some basic notes on setting this up, and provided some files to simplify and speed up the process. Jump in and join Fedora-ARM, the water's nice!
Dear Lazyweb: How can you find a process ID given a window ID? Mon, Nov 23. 2009
As far as I know, there is no way to reliably get a process ID from an X window ID for local clients (to implement Richard's View Source idea). I would love to be wrong!
(1) Did I miss something? Can this be done now?
(2) If this can't be done now, what would it take? Could we create an X extension so that the server can supply connection info for a window, and then trace that connection info back to a specific process?
