1. Schedules/testing: This week was “feature freeze” and by the end of the week we were very close to finalizing the feature set for the Trial-3 software release. Since there were a lot of new features getting checked in, we saw numerous builds and wrote up and fixed many, many blocking and regression bugs. Over the next week we will be focused on stability, through bug fixing and testing. There was some good progress on some of the biggest (and loudest) bugs related to suspend and resume, which is great to see. No more features for Trial-3. If you think there is an exception to this rule, please contact Jim Gettys and Kim Quirk.
1. Ethiopia: Nicholas gave the keynote at UN hosted World Information Technology Forum at which 52 countries were present, virtually all African nations.


2. Sugar: The Collabora team continued to work on final items before the upcoming software release. This included adding support for mutable activity properties (name, tags, colors, etc), invitation support, porting of many of the activities over to the new tubes specification and cleaning up a lot of the base system elements. Morgan Collett updated the Connect and Chat activities to the new interfaces.
2. Breaza: As part of our on-going outreach in Romania, OLPC intern Joel Stanley gave a presentation to Forum IT, an annual five-day computer summer camp for young people in Romania, run by Catalin Grosu (See http://tabara.forumit.ro/2007/arhiva.php).


If no school server is chosen, a presence server in the MIT collocation center is being used to enable individual developers to share.
3. Microscope: TB, malaria, and HIV/AIDS kill about 6M people a year in resource-poor areas. Simple, afford diagnostic methods for these diseases could save many lives. Our video-microscope add-on to the XO may help with the diagnostics efforts: HIV/AIDS can diagnosed through video microscopicy with signal processing: an automating method to count T-Cells. TB (including drug-resistant TB) and malaria can be diagnosed in similar ways. We are discussing the best way to proceed with Dr. Howard Shapiro, who runs the Center of Microbial Cytometry and wrote the widely used textbook, Practical Flow Cytometry, which can be read online free of charge (See
http://probes.invitrogen.com/products/flowcytometry/practicalflowcytometry.html). Howard has already developed low-cost cytometers for this purpose.


A new version of TamTam from Jean Piché's team is included in the new builds.
4. Pippy: Chris Ball released a Python-programming activity called Pippy, which is in the base image as of Build 553. It is a simple programming console in the style of the consoles for basic interpreted languages that many of us grew up with, and comes with a selection of introductory Python code. The next goal is to make it easy for children to distribute activities that consist of the code they've written.


Pango (to enable support for languages like Amharic) and Cairo were updated to their latest versions.
5. Wireless resume: Chris Ball spent most of the week working on the wireless-resume problem. Javier Cardona and USB experts at Marvell have been coming up with firmware patches. They are making progress—the number of successful resumes we get per cycle is increasing.


Chris Ball updated Pippy to add journal integration, sound support from Nathanaël Lécaudé and the TamTam team, and new examples from Madeleine Ball, Mel Chua, and Rafael Ortiz.
6. Kernel: Andres Salomon fixed some build failures due to kernel config and sent the patch upstream. Our build scripts needed to be updated as well, so that was done. With that out of the way, Andres took the opportunity to do a large update of our kernel config. This included enabling network and sound drivers used by VMware and Virtualbox, dropping some unused NAND drivers (including ATest NAND support), fixing IPv6, and building some drivers statically. Andres also reviewed a number of vserver updates and committed some of them.


Simon Schamijer updated the Memorize activity for the new tubes API.
7. School server: John Watlington announced a build (125) for testing. It is missing a number of crucial services, but verifies the build and installation process and supports laptops on the mesh. It should install on most x86 platforms, requiring only an Active Antenna to provide the mesh interface. More information is available from the wiki (See [[XS_Server_Software]]). You can also obtain the Live CD image (from http://xs-dev.laptop.org/xs/OLPC_XS_LATEST.iso). Release notes and installation instructions are also in the wiki (See [[XS_Installing_Software]]). Over the next week, we hope to include all required services in this build. Thanks go to Holger Levsen, Dan Margo, Scott Ananian, and RedHat team.


Simon also has been working on a the web browser (See the new visual design at [[Web_Browser]]). He added a sharable link tray and fixed bugs in the shared browser session.
8. Updates and security: Scott Ananian—with help from Ivan Krstić, Michael Stone, Noah Kantrowitz, and Mitch Bradley—wrote or edited the following specifications in the wiki:


Marc Maurer worked on the Abiword (Write Activity) collaboration backend. He also added a new format toolbar to Write and added some additional style options (headings, numbering, bullets, etc.) He also added the ability to insert images into Write directly from the Journal.
* [[Manifest_Specification]]
* [[Firmware_Security]]
* [[Firmware_Key_and_Signature_Formats]]
* [[Early_Boot]]
* [[Cheat_codes]]
* [[Yellow_Treaps]]


3. Upgrades and multi-boot: Scott Ananian installed Debian Linux alongside Fedora Sugar on an XO as a demonstration of the new upgrade mechanism, which allows you to keep the old version around and boot into if the upgrade goes awry; and the P_SF_RUN Bitfrost security mechanism, which allows a child to poke around the root filesystem and muck with things, while still being able to revert to the “pristine” OS image if things go wrong (See preliminary instructions at [[Installing_Debian_as_an_upgrade]]. This will get much easier next week as the rest of the upgrade infrastructure is rolled out: you will be able to just subscribe to the “debian” stream to get Debian installed (for example). There will be “stable” and “devel” streams for Sugar releases—the real point of this work.
Scott also made good progress towards getting boot-from-multiple-images support into the initial ramdisk, a component of our improved upgrade code. Scott worked on the auto-reinstallation image, hand-holding users through the new auto-reinstallation process and debugging some genuine problems.


4. X Window System: Bernardo Innocenti merged more xkb changes for our existing keymaps, defined a few missing keysyms and updated the olpc patch in
9. Firmware: Lilian Walter got the router to advertise a DNS IPv6 address and the code to use those data. For completeness, she is working on setting up DHCP6s to do the same. Mitch Bradley released Q2C25; he is focusing on security support in the firmware
response to Sergey Udaltsov 's reviews. He is currently testing new RPMs. A new patch submission is due soon.


Bernie and Walter Bender have also been finalizing the keyboard layouts for mass production (By way of example, see [[:Image:Keyboard_english.png]]).
10. Schedules: Monday is feature freeze for Trial-3. We will be following up on all unfinished features to see how to close them down or move them out. We will start attacking the blocking and high-priority bugs starting next week.


5. Embedded controller: Richard worked on the “battery-always-charging” bug. It does not appear to be just an EC problem as Open Firmware shows the correct status but the kernel does not. They both use the same EC commands. It is still unclear what is wrong.
11. Testing: There was regression over the past week, especially in activities, but by the end of the week, many fixes had been checked in. Check this weekend's build (557). Please write up your notes in the wiki (See [[Test_Group_Release_Notes]]).


6. The Wireless Bug (Trac #1835): Richard is also working on this bug. The more he gets into it, the more it smells like hardware. On a resume, after some number of cycles, the machine will hang. It is likely that we are not getting good data from the reset-vector fetch. The next step is to decode the LPC (low pin-count) bus and see what data is coming back in the fail case.
12. MaMaMedia: The MaMaMedia team has a new release for Build 542 that includes seven activities, including a Jigsaw Puzzle, Poll Builder, and Slider Puzzle feature mesh-based creative and collaborative sharing; and a Learning Center as a place for teachers and students to share learning tips. All of activities are now using the (almost) stabilized Sugar features: journal, clipboard, and tubes for sharing. Many thanks to Carla Gomez Monroy, SJ Klein, and Lauren Klein for their feedback and to Lincoln Quirk, Eben Eliason, and Marco Gritti for their collaboration with Morgan Collett, Carlos Neves, Terrence Grannum, Ed Stoner, Rich Goehl, and Shannon Sullivan (See http://www.worldwideworkshop.org/olpcwiki/index.php?title=MaMaMedia_Activity_Center and http://www.worldwideworkshop.org/olpcwiki/index.php?title=Teacher_Center).


Javier Cardona and Chris Ball also continued work on the wireless-resume bug. Javier added debugging code that is providing useful information on each crash, and is continuing to try to iron out the bugs as we find them.
13. Map creation: Christopher Schmidt, Schuyler Erle, and SJ Klein worked out a process for turning existing map-layer tools and public data into a lightweight browsable atlas, whose most detailed layer links out to text or image content. This should be able to run on an XO, with tiles generated by libraries on a server. Early versions are working online as a browsable page. Christopher is working on an activity version that clones Browse.


Richard and Chris found a bug where the CPU occasionally on resume appears to be stalling instead of executing instructions. Since this happens during our extreme-traffic wireless-resume testing, the problem could be as simple as us not giving the power rails enough time to quiesce. Richard is working on it.
14. Games: Roberto Faga got a lightweight NES emulator to work on the XO, with a set of bundles or ROMs. We need a copyright release on the ROMs and source code from Nintendo (or the original publishers) before we could ship them. Patrick Dejarnette got his Side-Scroller engine working, and is now developing images and some levels over the weekend (See wiki.laptop.org/go/Side-scroller).


7. School server: The school server software continues to improve; a new release with several bug fixes and the laptop registration service is expected by the beginning of next week. To aid in server development in crowded work areas (such as Cambridge), John Watlington tested and documented the mesh blinding tables (See [[Mesh_Debug]]). Several new school servers came online this week: one for a trial in India, one for content development, and several for testing in Cambridge.
15. Content Jams: Brendan Ballou in NYC is organizing a content jam for September 21-23 around news and journalism; they have their organizational team and a test group set up. Roberto Faga is also preparing a Game Jam in Brazil for the end of September; he is looking for interested Portuguese-speakers to help out.


8. Kernel: This week Andres Salomon worked on vserver patches and fixing sound bugs. The screeching-upon-resume bug has been fixed, along with a number of other sound bugs. The patches been pushed upstream. A few bugs still remain, but no known major ones.
16. Misc. activities: Lauren Klein and Charles Smith are continuing to work on a Bug Blitz activity and plan to have something to test next week. Some biologists from Argentina have offered to help with the project by reviewing photographs to help identify bugs and other life that children photograph in their vicinity.


Marcelo Tosatti added code to our kernels that makes it possible to trace how long suspend/resume cycles take. This should allow us to pinpoint where we spend a lot of our time. Currently, the largest consumer of time turns out to be writing to the serial console during resume.
An activity that need support and work: a simple video editor for splicing together images and video and matching them with spoken sentences (See [[ColingoXO]]).


9. Firmware: Mitch Bradley Released Q2C26 firmware with OS security and activation support, some bug fixes, improved NAND FLASH bad-block management, and created a kit for creating signed OS images and leases. Lilian Walter put into place the code to solicit stateless DHCPv6 information. She is finishing up IPv6 fragmentation and reassembly.
17. Grassroots: OLPC Philippines is gathering local interest; a Manila content jam is planned for the start of October, and they are filing papers to set up their own local nonprofit. OLPC Indonesia is starting to take shape as well; they have recruited a number of interested people and set up their own Indonesian-language mailing list (See [[OLPC_Indonesia]] and http://groups.google.com/group/olpc-indonesia).

10. Wireless: Michail borrowed an Anritsu Network analyzer and did some antenna performance measurements on the C- and B- Build laptops. He is happy to report that the C Build units are the first ones with completely functioning antennas. Quanta has implemented grounding of the antenna cable's shield in the C-Build machine and that seems to have made the right antenna perform properly. Michail’s only comment is that the insulation on the left antenna's wire is being stripped too short: the braid deforms from the mechanical stress imposed on it during the antenna's rotation. The insulation has to be left intact all the way to the grounding sticker as it the case with the right antenna.

Note: the C-Build laptops have metalization all around the plastic parts. Because of that, when the antennas are closed, the plastic below them acts as a ground plane and diminishes the antenna's performance completely compared to the previous builds. The antennas work much better when in the up position on the C-Build laptops.

11. Build 542.3: John (J5) Palmieri reports that a new spin of the stable build fixes a bug in Sugar that had prevented the installation of translation files; it also fixes a Journal bug for the Spanish locale.

http://olpc.download.redhat.com/olpc/streams/development/build542.3/

When installing this image, it should be named 'os5423.img' (along with the corresponding 'os5423.crc'). The FAT file system would otherwise be unhappy with the double dots in the names and the auto-reinstallation script would thus refuse to install them.
