Week of June 30 - July 2

Continued working on Fedora 9 bug wrangling and the Record activity.

Week of June 23 - June 27

Fedora 9 has been merged into Joyride. I've spent a lot of time chasing up the appropriate people to get the fixes included in builds, and I've also been working on the following:

• gnash crash bug (<trac>7306</trac>)
• Reworking the capture pipeline of the Record activity, the existing pipeline was broken (we're not sure why it worked on Fedora 7).

Week of June 16 - June 20

I've spent all week fixing up various problems with the Fedora 9 (OLPC-3) stream:

• Worked on olpc3 problems: no USB automount (#7289), can't reboot/shutdown (#7266), sound nodes not accessible to olpc user (#7302). Turns out all of these are caused by changes to the way that the HAL/PolicyKit/ConsoleKit stack works.
• Figured out the olpc3 OV7670 (camera driver) occasional crash-on-boot bug (#7252), waiting for Jon Corbet to attempt a proper fix before I suggest that we revert to the previous state of the driver.
• Integrated olpc-dm with ConsoleKit connector so that olpc-dm registers a session in hope that ConsoleKit can track it. However, architectural problems with olpc-dm prevent this from working properly at this stage.
• Fixed olpc3 problem with lack of presence functionality (#7319)
• Worked on restoring camera functionality in olpc3 (#7294)

Week of June 9 - June 13

• Started my internship on the 11th.
• Worked with Ankur and Chris Carrick to learn how to install the school server, and demonstrated it to the grassroots group
• Worked on a weird sudo message in OLPC-3 (#7267) as an introduction to RPM devel/handling
• Worked on NetworkManager OLPC-3 problems (#7271) which was non-functional
• attacked olpc-3 keyboard problems (#5952)
• attending grassroots jam in NY this weekend
