> 11. Sugar: Marco Gritti, Michael Stone, and Tomeu Vizoso worked on the
> integration of the Rainbow security system with Sugar and the
> DataStore (and Journal). They enabled activity isolation on Tuesday
> and solved all the known road blockers in the following days: access
> to
> audio and video resources; communication with the DataStore;
> activity-space directories and their permission; and out-of-container
> activities. Next week we will need a new round of testing; Marco is
> confident that we will be able to solve the remaining problems
> quickly.
> Marco rewrote the preview code to be much more efficient; it blocks
> for only the minimal required time. Switching between views and
> closing
> activities is now much faster and the previews are saved reliably.
> Marco temporarily disabled the startup sound in sugar to avoid
> blocking the sound device and tracked down the problem with muted
> audio at startup. Sound is expected to be finally back working fully
> in the next build.
> Tomeu implement a basic search in the mesh view, which greatly
> facilitates finding people on a crowded network; he exposed files from
> the DataStore to activities using hard links instead of doing a copy;
> and he made the DataStore's use of the temporary file space more
> efficient.
> Reinier Heeres added a way to switch between activities using ALT-Tab;
> fixed some issues with left-right inversion for Arabic; disabled
> closing the Journal with CTRL-Q;  and implemented a short-term
> solution to the problem of the "donut" on the home page not accurately
> reflecting activity memory usage. Reinier is working currently fixing
> some palette issues.
> 12. Activities: The Etoys team continues to make adjustments to the
> Sugar and Rainbow (security) system changes being introduced for
> Update.1; Bert Freudenberg is leading this effort. Yoshiki Ohshima and
> Bert have provided an improved version of Sugar menu bar; Yoshiki,
> Bert, and Scott Wallace put together the necessary bits to provide
> better "view source" experience?all of the code for Etoys can now be
> viewed without any degradation. Ted Kaehler and Kathleen Harness have
> been improving the help system for Etoys. Takashi Yamamiya and
> korakurider have stabilized the localization mechanism. Takashi also
> experimented a different UI for controlling choices in tiles.
> Simon Schampijer and Mark Maurer collaborated on getting "view source"
> working fluidly between the Browse and Write activities. By typing
> FN-Space (or CTRL+U) in Browse, the HTML source of the current page is
> opened in Write. The HTML can be edited in Write and when resumed from
> the Journal the modified page gets interpreted and displayed. While
> doing this work, they tracked down and fixed a new issue with the
> DataStore: it had been losing metadata between reboots.
> 13. Builds: C. Scott Ananian continued to work on forking the new
> stable Update.1 branch and stabilizing our build process. He setup
> download.laptop.org, mock.laptop.org, and pilgrim.laptop.org, which
> you should see being pressed into use in the next week. Scott also
> updated the Libertas firmware in the builds and refreshed the mesh
> testbed, with an eye towards testing the new firmware in a realistic
> network upgrade scenario.  He should be able to run that test on
> Monday.
> This week Andres Salomon cleaned up the kernel build scripts, made
> them auto-generate change logs, and dealt with getting updated kernels
> into joyride. Joyride builds now include sane kernels. Andres also did
> minor Libertas testing, and is in the process of debugging USB issues.
> 14. Power management: James Cameron and Chris Ball worked on some OHM
> (power manager) bugs. Once those were out of the way, Chris went on to
> implement some of our power management features:  "suspend on idle" is
> in place; there is now a distinction between "suspend" (screen and
> wireless still on, wake up on network traffic or key press) and
> "sleep" (screen off, only wake up on a power-button press). There are
> a few more OHM bugs to fight before this is ready to land in
> Joyride/Update.1, which should happen sometime early next week.
> 15. Localization: Sayamindu Dasgupta and Xavier Alvarez have
> successfully completed the first phase of the Pootle installation. All
> of the translation files are in place. A number of users have signed

> The next stage of the Pootle deployment will consist of making the GIT
> integration work?we are waiting for GIT write access to dev.laptop.org
> to go forward on that. A set of frequently asked questions (FAQ) has
> been created in the wiki (See http://wiki.laptop.org/go/Pootle/FAQ).
> Sayamindu has been looking at an issue where fontconfig seems to treat
> the font cache invalid if the mtime of the cache is greater than the
> system time. This is documented in Ticket #1525 (and in upstream
> Freedesktop bug #12107). Sayamindu had backported the relevant changes
> to the fontconfig used in Fedora 7; he will be testing out the package
> in the XO over the weekend.
> 16. Security: Michael Stone announced a new release of Rainbow (See
> http://koji.fedoraproject.org/koji/taskinfo?taskID=234221) to the
> devel and sugar lists today. The release incorporates a number of
> resolutions to the current crop of 'rainbow-integration' bugs that the
> community has worked so hard over the last three days to document for
> us.
> Changes include:
>  ? relaxed multimedia-device permissions that should make it possible
> for activities to use the camera, microphone, and speakers;
>  ? availability of the user's public key;
>  ? activities are now started in $SUGAR_BUNDLE_PATH instead of
>  ? activities can run under "strace" by defining the environment
> variable RAINBOW_STRACE_LOG (in the dictionary passed to Rainbow in
> /usr/lib/python2.5/site-packages/sugar/activity/activityfactory.py);
>  ? tracebacks of your activity's log file can be viewed with "less -R"
> (e.g., less -R /home/olpc/.sugar/default/logs/org.laptop.Record-1.log);
> Special thanks Marco, Tomeu, and Alex L. for their extraordinary efforts.
> 17. Community reporting: Dan Sutera and the team working on the Report
> activity made it to the next round of the Knight News Challenge.
> Pablo Flores is working on something similar in Uruguay, and has found
> some federal support to develop local blogs from children, stored at
> the local schools. We discussed how the projects could work together;
> Pablo is focusing on the web activity that would help editors arrange
> blog feeds into beautiful editions, and the Report team is working on
> an XO activity that would let children read and write blog and news
> feeds. Meanwhile, Jack Driscoll, former editor of the Boston Globe?who
>  has been leading community journalism projects around the world for
> over ten years?has put some journalism guidelines in the wiki (See
> http://wiki.laptop.org/go/Learning_activities/Journalism).
> 18. SimCity: SimCity is now available under the GPL, thanks to the
> generosity of EA and the hard work of Steve Seabolt and Chuck Normann,
> John Gilmore, and Don Hopkins (See http://wiki.laptop.org/go/SimCity).
> The game is in the process of being "sugarized", but is already
> playable on the XO. This is the first time that a major publisher has
> open sourced the original of a popular title. EA should be
> congratulated.
> 19. Game Jams: A competitive game jam is under way this weekend in S?o
> Carlos, Brazil, with the support of a number of local universities and
> sponsors. Any who are interested in their progress are welcome to
> follow along in #olpc-content on IRC; they are looking for outside
> help with art and music for the developed games (See
> http://wiki.laptop.org/go/Game_Jam_Brazil). In advance of the CMU
> game jam next weekend, the ETC team at Carnegie Mellon university has
> finished a draft of its first game, a peg solitaire affair (See
> http://www.olpcgames.org/).
> 20. Community: A discussion with Greg DeKoenigsberg about how to
> involve more Fedora developers in OLPC work led to some work on
> improving test and review processes for activities and bundles (See
> http://wiki.laptop.org/go/Activity_Testing_Project).
