1. Walter Bender met with Carole Wacey of Mouse.org. Mouse works with youth on technology mentoring programs. Children at Mouse.org are already actively engaged in authoring tutorials and videos about the XO and the older children (middle and high school) are interested in mentoring the elementary-school children who would be getting the XOs.


1. Montevideo: We’ve only just begun!! The first deployment machines were handed out in Escuela No. 109 in Florida, a rural department of Uruguay. The second batch was handed out in Escuela No. 24 in Villa Cardal, which has been a pilot site since May of this year. In Cardal, we gave children production XOs and collecting their old Beta-2 units. The OLPC deployment in Uruguay is being run by Miguel Brechner as part of Proyecto Ceibal (Ceibo is the national flower of Uruguay), a presidential initiative to equip each child with a laptop. The Ceibal offices are housed in a Montevideo complex called LATU, or Laboratorio Tecnológico del Uruguay, which is a public/private sector cooperative technical lab now responsible for much of Uruguay’s technical certification and quality control programs, as well as serving an incubator role for various engineering and technical projects. The OLPC team has put all of their blood, sweat and code into the project over the past three years because of the unshaken belief that it is the right thing to do. Now it is real. You can read more about our first deployment on Ivan Krstić’s blog (See http://radian.org/notebook/first-deployment).
2. New York: A team from OLPC and Red Hat spent two days at Pentagram working through the outstanding design issues for the first release software on the XO. Together, we made significant progress on the Journal and sharing among groups. Simplicity was our mantra: look forward to more clarity to user interface.
At the day the most of the schools in Florida are visited by the volunteers from DESEM and other ONG's thtat deliver the XO to all the children in the region.


2. Changshu: Mass Production is now very stable. We are using our line at 100% capacity. Congratulations to Quanta for stabilizing production just three weeks after MP start.
3. Villa Cardal: While anyone can watch videos on YouTube, children with XOs are posting videos. A video shot on an XO, “parto de una vaca (birth of a calf),” was posted by a 10-year-old child who is participating in the Villa Cardal trial in Uruguay (Please see http://www.youtube.com:80/watch?v=BOzBTGGVWNg).


3. G1G1: Every “Day 1” Give One Get One participant (those that donated on November 12, the first day of our campaign) received email on Wednesday informing them to expect their “Get” laptops between December 14 and 24. Delivery windows for other G1G1 participants were calculated and posted: “Get” laptops ordered thus far will be arriving, at the latest, by mid-January 2008. Brightstar and OLPC have been working closely to determine when the complicated logistics of laptop delivery can be promised.
4. Texture and color: Quanta, Foxconn, ZYE, and Fuse Project worked around the clock and through the weekend in order to complete the color and finish review of all parts of the XO. Clear finish guidelines have been established and the color has been tuned to our specification. Not all texture changes are completed, but established parts have been created to serve as reference for both Foxconn and ZYE; both companies are confident that they will be able to match the referenced samples. Two complete sets of C-build mechanicals are en route to OLPC for final approval for the mass production (MP) build.


4. AC adapters: There has been a request for AC adapters that are rotated ninety degrees from the current configuration. In order to rotate the orientation of the prongs, the width of the adapter must be extended (to satisfy the safety requirement). As a result, six reoriented AC adapters will not fit abreast in the standard spacing of a six-plug power strip. Mary Lou Jepsen and Fuse are investigating further; if we can not resolve the issue, we will not make AC adapters with a rotated prong orientation.
5. $1 video microscope: A video of Mary Lou's prototype microscope attachment for the XO video camera is posted on the web (Please see http://www.youtube.com/watch?v=wI28-IS9AII). In the video, she compares various LCD screens. The microscope, which has ~ 100× magnification, could be useful to analyzing water quality, among other things.


5. Schedules: This was the week to release “Ship.2”, a build to improve upon network upgrades, wireless problems, and our ability to connect to T-mobile services. Although the week had its ups and downs, it ended with successes on all of these fronts and we have Release 649 as the candidate, barring any last-minute problems in testing this weekend. The Ship.2 Build connects successfully to many different access points; we believe we have fixed the “lazyWDS” issue (which could have potentially caused problems in multi-access-point environments with other 802.11b/g laptops and XOs); and we are successfully connecting to T-mobile services after setting an appropriate configuration for the browser. The Roadmap has been updated (http://dev.laptop.org/roadmap); please send Kim Quirk any new feature/product ideas so they can be scheduled into upcoming releases.
6. Schedules: We have declared Trial-2 software to be Build 542, which we released to Quanta for the C-build on Thursday evening. This is alpha-level software and it becomes the new stable branch. Critical issues that may still need to be addressed will be back ported to Build 542, but this will allow development to continue toward Trial-3. Please note that we haven’t completed our optimization of memory usage in Build 542; if you are running on B2-1 hardware—which only has 128MB of DRAM—you are advised to hold off on upgrading.


The release candidate for the G1G1 program is Build 649 and will be called Ship.2. Final testing is underway, specifically for network
7. Trial-2 build: Most of our vision for the first generation OLPC software is now present; Build 542 shows off many important collaboration, connectivity, and Journal features, including: real-time collaboration in many activities (Write, Read, Chat, Record, Etoys, TamTam, Memorize, Connect4, etc.); support for automatic configuration of mesh portal points (MPP) and automatic configuration of ad-hoc meshes (allowing collaboration without any dependency on infrastructure or Internet access); anti-theft activation on installation; and registration with and backup to a school server.
issues that have been reported. The wireless team of Ricardo Carrano, Michail Bletsas, Javiar Cardona, Ashish Shukla, David Woodhouse, Marcelo Tosatti, Ronak Chokshi of OLPC, Marvell, RedHat, and Cozybit worked hard on these issues of both the Linux driver and the Marvell wireless
firmware and worked out a solution, which is now in final test, under great pressure. Ship.2 has most of the user visible features of the
planned Update.1 release, but has Bitfrost security turned off and lacking the advanced OHM-based power management with aggressive suspend and resume and ebook mode. Both of these major features are now operating in our Joyride test builds, but there were too many open
issues to enable Bitfrost or to ship OHM power management.


6. Testing: This weekend Michail Bletsas and Ricardo Carrano are testing 40+ XOs with a number of access points and traditional 802.11b/g laptops to “prove” the fix for the WDS problems that have been plaguing us for a while. Thanks to Marvell for their debugging and test builds to find a good work around; and special thanks to the volunteers in the office who activated and upgraded all the laptops in preparation for this testing: Andriani Ferti, Danny Clark, Adam Holt, Alex Latham, and Eben Eliason.
A draft of the Software Release Notes can be found in the OLPC wiki (See [[OLPC Trial-2 Software Release Notes]]). The B4 Hardware Release Notes are also found in the wiki (Please see [[BTest-4 Release Notes]]).


7. Support: Adam Holt joined OLPC this week as our Support Engineer focused on tracking, debugging and follow up of customer problems from the field. He is an MIT graduate who has worked in software development, support, and systems integration. Most recently he comes from Jenzabar in Boston. He was a great help in his first week as we were testing and configuring laptops for Ship.2 Release.
As noted above, Build 542 is not suitable for B2-1 systems: memory usage is higher than desired, due to surprises such as a 20MB DHCPD server that we will be replacing (there are several smaller ones to choose from). Also note that the mesh wire packet protocol has changed, so mixtures of builds before 438 and current builds cannot use the same mesh.


8. Wireless: Michail Bletsas reports great progress was made this week in circumventing a problem that we had with access points that were misinterpreting our mesh frames as wireless backbone frames, resulting in the creation of erratic ad-hoc wireless network topologies. These were access points (APs) utilizing wireless adapters from Broadcom as the ubiquitous Linksys WRT54. We have alerted Broadcom to the issue (if the standard doesn't change, 802.11s devices will be rendering these APs useless unless they address that behavior) and we have worked around it by changing our broadcast and multicast mesh frames to use 3-address frames instead of the 4-address WDS frames that the Broadcom APs are already using. Thanks to Javier Cardona, a dedicated team at Marvell, and Ricardo Carrano for implementing and testing this in time for our Ship.2 Release. Javier will be submitting this change for consideration in the next standards committee meeting. This change requires no driver/software changes on the XOs and is implemented completely in firmware. The important point to note is that all XOs in a mesh have to be running the new firmware (5.110.20.p42) for them to be able to collaborate via the mesh.
8. Autoreinstallation and upgrade: Scott Ananian continues to work on the autoreinstallation image. Scott and Chris Ball wrote an upgrade script that preserves the user's home directory, which Kim Quirk has been testing this week. Mitch Bradley, Richard Smith, John Palmieri, and Jim Gettys found a FAT32 corruption bug in the current firmware which ate USB keys. Mitch fixed this bug in q2c20d (and later).


Michail et al. had great fun at OLPC in the later half of this week. Somebody was using a wireless device that was acting as a jammer for the center part of the 2.4Ghz band. Despite all the troubles that it caused us by preventing us from doing any serious testing of the laptops, we should be thanking him/her since the extremely difficult environment helped expose a serious issue with wireless operation in congested environments which has probably bitten us in the past and which we had never had the opportunity to properly diagnose and debug. The problem has been pinpointed to the scan routines in the firmware and is being currently addressed. Testing with a jammer present is now a requirement (not your usual WiFi test ;-).
Scott also continued work on activation and the initial ramdisk, into which the XO boots. Scott also implemented Eben Eliason's design for an activation GUI (trac #1328), which should appear in Trial-3 builds. Scott also did some more work on network activation from the School Server, with help from Dan Williams and the Cozybit team.


9. Sugar: Simon Schampijer fixed memorize again to release the sound device and put the drumgit game back in the distribution which is the only demo game we have which includes sound (in current joyride). He added an “About this XO” entry to the menu you get when hovering over the XO icon in the home view: this brings up a window with information about the current build, firmware and serial number of this XO. With Mako Hill, SJ Klein and Marco Pesenti Gritti, Simon worked on the library fixes for Ship.2 which included a fix for Sugar (Ticket #2856). Marco and Simon added as well support for the OLPC Root CA into the browser. You can test this by pointing your browser to https://activation.laptop.org in the current Ship.2 build.
9. Firmware and embedded controller (EC): Richard spent the entire week dealing with a few critical EC problems; He and Andres Salomon made progress was made on “wakeup event is repeated continuously” bug (trac #2401), when they discovered a deadlock in the EC code. Unfortunately, it's not trivial to fix, but they are testing possible workarounds.


Marco reviewed several patches with small UI improvements (to the interaction with palettes in particular) and bug fixes for Update.1 and packaged them in joyride for testing. Marco also tracked down two different issues with the datastore which was causing activities to not start. Fixes for both of them landed into Joyride. Finally, he changed the default Jabber server for Ship.2.
Chris wrote a kernel patch to set the EC wakeup event mask such that 1% battery charge changes don't bring us back out of suspend. If we suspend with Build 542, we should stay suspended until we get the “battery low” signal to wake us up.


Reinier Herres worked working with Marco to build a new evince version for the Read activity, which will probably be available early next week. He also released a new Calculate with some bug-fixes.
Richard received PQ2C20 from Quanta and integrated it into the new firmware releases. We released PQ2C20, 21 and 22 this week. C20 contained the bulk of the EC fixes. C21 and C22 were needed to repair some new OFW bugs that surfaced, most notably the FAT32 corruption bug, which had been responsible for upgrade failures.


Morgan Collett worked on Chat to fix scrolling issues—he made it not automatically scroll on new messages if you scrolled up to read the log and worked on copying URLs to the clipboard (#5080); he found some issues with clipboard handling in Sugar. We will land the Chat and Sugar changes when the Ship.2 dust settles. He also worked on the Presence Service: preforming lots of testing on Ship.2 and Joyride builds, testing recent fixes.
Mitch Bradley released firmware for C-build. He also worked on activation and security support for the firmware, and integrated Lilian Walter's IPv6 firmware support; he hopes to test it in Cambridge next week.


Memorize: Muriel Godoi reports that Memorize was launching under Rainbow, but wasn’t saving games in datastore; after some chats with Michael Stone, they realize that Memorize is creating new sub-folders inside their instance folder using tempfile library under permission 700 denying the access when trying to write into it. Changing the folder permission fixed that problem. Muriel also fixed the mime-type icon file location and added ogg support.
Lilian finally made one of Linux boxes into an IPv6 router tunneling to the IPv6 internet. Other Linux boxes with IPv6 enabled can get on to the IPv6 internet also. Next, she will work on implementing the router advertisement/notification and global address/prefix in OFW so that it can get on the IPv6 internet also.


Muriel also reports that Food Force had some UI improvements, such as a message bar where contextualized educational messages to the player will be displayed. The code will be posted to his public_git next week.
We thank Zephaniah Hull for providing us patches to perform touchpad and keyboard resets on ESD events.


10. Etoys: For Ship.2 release, Etoys team packaged a new version that has the progress made since Ship.1. Bert Freudenberg has been carefully working to adapt changes in Sugar while keeping the compatibility with old Sugar so that the latest work can be back ported. In this week, Yoshiki Ohshima and Bert improved the sharing experience and Takashi Yamamiya fixed a bug in script editing interface to make the version for Ship.2 be very comfortable. In the meantime, Scott Wallace took a pass on making an IDE for a traditional text file based programming system on Squeak, which may be useful for making an IDE for XO.
Joel Stanley worked on tool chain for OpenEC. He submitted patch to srecord after fixing a bug in their build system. And he reworked script for power instrumentation so it can be included in Chris Ball’s tinderbox regression-testing system.


11. Localization: Xavi Alvarez and Sayamindu Dasgupta have finally put the GIT integration of the Translation Infrastructure (Pootle) in place in a fully working form. Translators can directly commit to GIT now via the Pootle web interface. We also have a new project in Pootle, called Update 1 (Core), which tracks the update-1 branch for a few core modules of the Sugar environment. From an average translation coverage of 23% at the beginning of the week, we have 33% average coverage now. Languages with more than 80% of Update 1 (Core) translated are:
Chris resurrected the tinderbox on our power-measurement XO and added suspend/resume testing with measurements for power use, memory use, and number of software wakeups. We have lost a lot of memory to the base OS during the Trial-2 buildup; having memory tracked per-build from now on will help better contain these problems.

10. School server: John Watlington continued to work on building a usable, repeatable school-server image. We are very close; the effort is
(100%)
now going into a script that finalizes the configuration after the image is installed onto a disk. Stable and testing repositories for the software packages going onto the school server have been established.

11. Security: Joel Stanley worked with refining Rainbow for integration into Trail 3. He fixed general bugs and worked with Michael Stone to refactor code for maintainability. He implemented the persistent scratch space, allowing Sugar activities to save to “/data” any files they wish to (e.g., TamTam audio samples); these files are restored on next run of the activity. This allows us to have all other aspects of the filesystem mounted read-only. Finally, he investigated sound support inside containers to implement P_DSP_BG, the Bitfrost permission to allow background activities to continue to play sound. Scott Ananian and Ivan Krstić worked out the details of the anti-theft client and server; Scott and Michael worked on early boot and upgrade integration with the Rainbow security service.

12. Etoys: The SqueakFest 2007 conference was held at Columbia College in Chicago. One of the major themes of the conference this year was OLPC; there were ~100 participants (from various countries including Brazil, South Africa, South Korea, Japan, Colombia, Nepal, and the US), many of them are involved in the OLPC pilot programs. Yoshiki Ohshima gave a talk on the OLPC project and the Etoys activity. Scott Wallace conducted a tutorial of advanced use of Etoys, Takashi Yamamiya explained the GetText interoperability feature at birds-of-a-feather gathering. Alan Kay gave a talk titled, “A Call for Content.” Unlike typical technology conferences, SqueakFest is focused on education; there were a lot of good discussion about learning in and between sessions.

13. Measure: Arjun Sarwal reports that the Measure Activity now features a frequency-domain representation in addition to a time-domain representation. Journal integration is complete. He also built a $1 temperature-sensing peripheral and a $1.50 intrusion alarm system; both have been tested using the measure activity. “The great thing about the XOs is that they are inherently networked, so by simply connecting a sensor to each XO, and using a combination of such sensors and the cameras, a highly powerful, flexible and robust sensor network for surveillance can be built.”

Polish
Arjun also had a very positive meeting with the Scratch team who are working on an XO port. He demonstrated the use of low-cost sensors around the measure activity. The demonstration, which utilizes the microphone port built into the XO rivaled the $25 board that is included with the PC version of Scratch. I would be helping them develop the analog input modules within Scratch.

14. Environmental testing: Four XOs have been running in an oven at temperatures above 45C for a continuous period of 6 days; they are running perfectly. This test is more extreme than real-life conditions, where at night the temperature generally goes down. A room humidifier has been placed in the oven, where is has been running continuously. None of the XOs show any problem.

Quite a few of the other languages are catching up quickly. A number of Indic language translation teams started work this week: Malayalam, Marathi, Punjabi, and Tamil. A Japanese project was also started this week. Waqas Toor and Salman Minhasreport that more than 85% of Urdu localization is completed.
15. OurStories: Stephen Cho, Google, reports that the OurStories engineering team has been through several iterations of potential solutions, and we have settled on what we hope to be a workable model for the first version of a story-collection website. The site will have the StoryCorps U.S. stories mapped on a Google Map, with the ability for users to find by location and download those stories. These are the roughly 3-minute edited versions of the stories that are on NPR on Fridays (roughly 300 stories for the U.S.). Stephen will over time work through the distribution rights issues to get all of the 12,000+ StoryCorps stories on the map. In addition, he is expecting 50 stories from Uganda and 50 stories from Pakistan through the UNICEF team. Uruguay is also looking to participate. The Museum of the Person project in Brazil also has several thousand audio stories.


Xavi and Sayamindu also managed to fix a few build breakages introduced by some issues in Pootle's PO generation code. Things should be running smoothly now (Sayamindu has also put in a logging framework in place that monitors the interaction between Pootle and GIT so that we can investigate potential problems easily later).
The team has developed a client application with which children will record stories on their XO laptops; these will be backed up to the OLPC school server. From there, stories can be uploaded and mapped. The enables children to record a story, play a story, share a story, and find a story. Plans are underway for testing the system at the school trial in Nigeria.


12. OLPC Pakistan: Waqas and Salman have initiated developing two e-Books and are busy working on an English to Urdu Glossary Project for OLPC.
16. Library: Library-creation scripts for making library bundles are now in git under “content-bundler”; a step towards automated builds of content images. A number of content publishers and platforms—Curriki (curriki.org), Connexions (cnx.org), CK12, and Jamendo (jamendo.org)—have committed to setting up simplified portals for creators who want to make OLPC material, and to adding an option to export books, music, or other collections as XO content bundles. CK12 and Connexions have full sets of books and modules available; Curriki is involved in the discussion of how to fill available gaps with wiki materials, and Jamendo has music across all continents and genres which its community are organizing into playlist-bundles. Sylvain Zimmer of Jamendo has developed bundling scripts for music, and Zdenek Broz has done the same for web sites, to simplify culling the pages from a directory of links into a usable content bundle. These will help curators with their own collections, and site-scrapers for dealing with open sites that do not have active curators.
A community list for support in Pakistan is up and running (Please see http://groups.google.com/group/olpc-pakistan and visit the #olpc-pakistan IRC channel on irc.freenode.net).


13. System programming: Chris Ball worked on OHM early in the week, Ship.2 testing towards the end. Bernie Innocenti has been squashing the last few input, localization and configuration bugs. Mostly in olpc-utils and xkeyboard-config and finished moving the rest of the Xorg packages to Fedora's repository and now has no packages built locally. He also helped SJ Klein apply blanket changes all over the dictionary to fixlinks and encoding errors. And he did some transformations for the start pages. Bernie also finished building a geode-optimized package of glibc 2.7 that looks very promising, but still needs testing and started packaging X 1.4.99 from Fedora development, which seems interesting for the various EXA improvements. There is some PCI rework needed in amd_drv before we can start doing some benchmarking. He is hoping to offload the rest of this work to Stefano “aleph” Fedrigo, who in the past has been doing some neat X performance analysis for us.
17. Licensing: Scott Shawcroft and Jason Kivlighn are looking into “Sugarizing” the Creative Commons (CC) liblicense chooser, as a first step in integrating it with creative applications on the XO. They have a working Sugar patch, but are revising it to make it less complicated.


Dennis Gilmore spent some time helping John Watlington and Michael Stone with some issues with the school server live image. He submitted a patch to upstream yum adding geode support and worked on a patch for rpm adding geode support should be done today or tomorrow. Dennis worked on some code to enable subscriptions to koji. This will let us import new builds into our own koji when we get it.
18. Language: Andrew Lee has been working on a SCIM-based input widget for Sugar; SCIM is used for Chinese and other stroke-based input (Please see http://wiki.tossug.org/OLPCinChinese).


Andres Salomon worked on the xorg evdev driver (*cry*), setting up general geode testing infrastructure, some participation in the libertas nonsense (*cry*^2), and some dcon debugging.
19. Wikis: Shoichi Chou has been working on a standalone browser for wiki-snapshots called Ksana (ksana.tw), which supports Unicode and RTL displays, fast on-the-fly indexing of any Mediawiki dump, and link-cleaning. It is more general than other available engines, and has a facility for loading dumps as modules. A French reader/browser, Moulin, is another option; it remains to compare how much CPU and RAM they use while reading a large snapshot.


14. Presence service: Guillaume Desmottes tested, modified and improve Dafydd Harries' patches for #4965; he did more ejbbard/Erlang investigations; reviewed Sjoerd Simons's Salut fixes; started to evaluate Openfire as alternative Jabber server; debugged and fixed a PEP problem in Gabble breaking sharing with Openfire (#5223); improved friends roster synchronization (#4965); fixed a Gabble bug when requestion lists channels (#5164); debugged and fixed a muc properties bug in Gabble breaking sharing with Openfire (#5224); and modified telepathy-python tubes examples to work with latest Salut.
Mako Hill’s [[MikMik]], the wiki client being considered for use on the laptops, received a face-lift this week; a suitable gateway service for merging offline edits with a global Wikipedia is being discussed—an editing API needed to support this kind of editing without visiting a web page is being developed by Yuri Astrakhan with support from Vodafone. Denny Vrandecic, one of the creators of Semantic Mediawiki wants to work on offline merging; his lab at the University of Karlsruhe is doing related software development.


Dafydd Harries worked on a more scalable XMPP protocol for activity management. Sjoerd Simons tested Salut for Ship.2 and fixed all outstanding Ship.2 issues it had.
20. Annotation: Alec Thomas and Alan Green, working on generalized content stamping at Google, confirmed that their work can be open sourced and are in active discussion about merging their work with existing work for OLPC (Please see [[Annotation]]; [[Original Annotation API Proposal]]; and
[[Comment Anywhere Annotation Protocol Proposal]]).


15. Multiple-battery charger: Tooling has been ordered; first prototypes will be available at the end of December or early January. The PCB for the production system is done. The question is how many to build for our first run. The current plan is to build twenty-five, but this may be increased if there is more interest from trials.
21. Jams: ccTaiwan helped organize a curriculum jam with a number of Taiwanese student and CC groups in Taipei. In the US, the Columbia Journalism School and Columbia Prep confirmed that they will run a NYC jam in October.


Lilian Walter is progressing nicely on the battery charger firmware. She has been working on implementing a LiFePO battery charging algorithm this week. She has charged a battery, and so far only damaged a single battery.
22. Summer of Content: The trial of the Summer of Content was broadly discussed this weekend (at Wikimania), with a number of brainstorming sessions about project ideas and mentors; it will run for 6 weeks starting August 17. The southern summer starting in early December will be the true launch of the project, with a target of 500 internships and 50 mentor organizations.


16. Firmware: Mitch Bradley and Richard Smith have released Q2D05 with miscellaneous bug fixes for Ship.2. This contains EC firmware with the software workaround for most of the suspend/resume problems and the now controversial (?) blink-power-LED-on-suspend. Since suspend/resume is disabled for Ship.2, these changes will not be apparent to the user.
23. Games: Lincoln Quirk has the mesh working nicely with olpcgames and pygame. Game developers and players alike are quite excited about this integration as it will make porting a number of existing multi-player games extremely easy. The chose-your-own-adventure framework that Roberto Faga is working on should be done in draft next week.


Wireless support from within OFW is still not totally robust. Mitch is unsure whether it is the WLAN firmware, the 1CC RF jamming, or an OFW driver problem. (Over the past week we have been unable to use WiFi channel 6 at 1CC due to constant, high level non-WiFi signal from an unknown source, the aforementioned jammer.)
24. Biology: The E.O. Wilson foundation is working on a simple Bug Blitz activity for XO communities. They have a rough draft out; Santi from the Thai team wants to try it with their children.


17. Touchpad: Richard Smith is now pretty convinced that our touchpad problems are caused by the auto-calibration feature of the touchpad. The two problems—undersensitivity and jitteriness—are opposite results of a bad recalibrate. By forcing a calibrate to happen with the touchpad in various conditions he can recreate our touchpad problems.
{{anchor|Upcoming Highlights:}}

“Jumpiness” is caused by over sensitivity. Duplicating this is bit harder. The best Richard has found is placing a large chunk of thick

rubber on the touchpad while the unit is on battery power and then recalibrate.

|}
A recalibration while the touchpad is in use causes under-sensitivity but we’re not sure how over-sensitivity happens the field. Nor do we yet
understand why some laptops are so much worse than others. We are arranging a conference call with ALPS to discuss the issue. The only “fix” Richard proposes is to disable auto-calibration. It seems that auto-calibration can't ever be made safe without some method of insuring that the touchpad is free and clear for the recalibration. It is unclear whether we still need to auto-calibrate, or if this was only needed for the problems seen with the B2 build.

18. School Server: School server development has restarted. It was discovered that previously distributed installers will no longer work due to a reliance on a now missing Fedora server. The build system also needed repair but seems to be behaving again. A new build is being tested and will be released over the weekend. This build will have no new features but will contain the latest wireless mesh firmware and drivers.

Laptop News 2007-12-01

1. Montevideo: We’ve only just begun!! The first deployment machines were handed out in Escuela No. 109 in Florida, a rural department of Uruguay. The second batch was handed out in Escuela No. 24 in Villa Cardal, which has been a pilot site since May of this year. In Cardal, we gave children production XOs and collecting their old Beta-2 units. The OLPC deployment in Uruguay is being run by Miguel Brechner as part of Proyecto Ceibal (Ceibo is the national flower of Uruguay), a presidential initiative to equip each child with a laptop. The Ceibal offices are housed in a Montevideo complex called LATU, or Laboratorio Tecnológico del Uruguay, which is a public/private sector cooperative technical lab now responsible for much of Uruguay’s technical certification and quality control programs, as well as serving an incubator role for various engineering and technical projects. The OLPC team has put all of their blood, sweat and code into the project over the past three years because of the unshaken belief that it is the right thing to do. Now it is real. You can read more about our first deployment on Ivan Krstić’s blog (See http://radian.org/notebook/first-deployment). At the day the most of the schools in Florida are visited by the volunteers from DESEM and other ONG's thtat deliver the XO to all the children in the region.

2. Changshu: Mass Production is now very stable. We are using our line at 100% capacity. Congratulations to Quanta for stabilizing production just three weeks after MP start.

3. G1G1: Every “Day 1” Give One Get One participant (those that donated on November 12, the first day of our campaign) received email on Wednesday informing them to expect their “Get” laptops between December 14 and 24. Delivery windows for other G1G1 participants were calculated and posted: “Get” laptops ordered thus far will be arriving, at the latest, by mid-January 2008. Brightstar and OLPC have been working closely to determine when the complicated logistics of laptop delivery can be promised.

4. AC adapters: There has been a request for AC adapters that are rotated ninety degrees from the current configuration. In order to rotate the orientation of the prongs, the width of the adapter must be extended (to satisfy the safety requirement). As a result, six reoriented AC adapters will not fit abreast in the standard spacing of a six-plug power strip. Mary Lou Jepsen and Fuse are investigating further; if we can not resolve the issue, we will not make AC adapters with a rotated prong orientation.

5. Schedules: This was the week to release “Ship.2”, a build to improve upon network upgrades, wireless problems, and our ability to connect to T-mobile services. Although the week had its ups and downs, it ended with successes on all of these fronts and we have Release 649 as the candidate, barring any last-minute problems in testing this weekend. The Ship.2 Build connects successfully to many different access points; we believe we have fixed the “lazyWDS” issue (which could have potentially caused problems in multi-access-point environments with other 802.11b/g laptops and XOs); and we are successfully connecting to T-mobile services after setting an appropriate configuration for the browser. The Roadmap has been updated (http://dev.laptop.org/roadmap); please send Kim Quirk any new feature/product ideas so they can be scheduled into upcoming releases.

The release candidate for the G1G1 program is Build 649 and will be called Ship.2. Final testing is underway, specifically for network issues that have been reported. The wireless team of Ricardo Carrano, Michail Bletsas, Javiar Cardona, Ashish Shukla, David Woodhouse, Marcelo Tosatti, Ronak Chokshi of OLPC, Marvell, RedHat, and Cozybit worked hard on these issues of both the Linux driver and the Marvell wireless firmware and worked out a solution, which is now in final test, under great pressure. Ship.2 has most of the user visible features of the planned Update.1 release, but has Bitfrost security turned off and lacking the advanced OHM-based power management with aggressive suspend and resume and ebook mode. Both of these major features are now operating in our Joyride test builds, but there were too many open issues to enable Bitfrost or to ship OHM power management.

6. Testing: This weekend Michail Bletsas and Ricardo Carrano are testing 40+ XOs with a number of access points and traditional 802.11b/g laptops to “prove” the fix for the WDS problems that have been plaguing us for a while. Thanks to Marvell for their debugging and test builds to find a good work around; and special thanks to the volunteers in the office who activated and upgraded all the laptops in preparation for this testing: Andriani Ferti, Danny Clark, Adam Holt, Alex Latham, and Eben Eliason.

7. Support: Adam Holt joined OLPC this week as our Support Engineer focused on tracking, debugging and follow up of customer problems from the field. He is an MIT graduate who has worked in software development, support, and systems integration. Most recently he comes from Jenzabar in Boston. He was a great help in his first week as we were testing and configuring laptops for Ship.2 Release.

8. Wireless: Michail Bletsas reports great progress was made this week in circumventing a problem that we had with access points that were misinterpreting our mesh frames as wireless backbone frames, resulting in the creation of erratic ad-hoc wireless network topologies. These were access points (APs) utilizing wireless adapters from Broadcom as the ubiquitous Linksys WRT54. We have alerted Broadcom to the issue (if the standard doesn't change, 802.11s devices will be rendering these APs useless unless they address that behavior) and we have worked around it by changing our broadcast and multicast mesh frames to use 3-address frames instead of the 4-address WDS frames that the Broadcom APs are already using. Thanks to Javier Cardona, a dedicated team at Marvell, and Ricardo Carrano for implementing and testing this in time for our Ship.2 Release. Javier will be submitting this change for consideration in the next standards committee meeting. This change requires no driver/software changes on the XOs and is implemented completely in firmware. The important point to note is that all XOs in a mesh have to be running the new firmware (5.110.20.p42) for them to be able to collaborate via the mesh.

Michail et al. had great fun at OLPC in the later half of this week. Somebody was using a wireless device that was acting as a jammer for the center part of the 2.4Ghz band. Despite all the troubles that it caused us by preventing us from doing any serious testing of the laptops, we should be thanking him/her since the extremely difficult environment helped expose a serious issue with wireless operation in congested environments which has probably bitten us in the past and which we had never had the opportunity to properly diagnose and debug. The problem has been pinpointed to the scan routines in the firmware and is being currently addressed. Testing with a jammer present is now a requirement (not your usual WiFi test ;-).

9. Sugar: Simon Schampijer fixed memorize again to release the sound device and put the drumgit game back in the distribution which is the only demo game we have which includes sound (in current joyride). He added an “About this XO” entry to the menu you get when hovering over the XO icon in the home view: this brings up a window with information about the current build, firmware and serial number of this XO. With Mako Hill, SJ Klein and Marco Pesenti Gritti, Simon worked on the library fixes for Ship.2 which included a fix for Sugar (Ticket #2856). Marco and Simon added as well support for the OLPC Root CA into the browser. You can test this by pointing your browser to https://activation.laptop.org in the current Ship.2 build.

Marco reviewed several patches with small UI improvements (to the interaction with palettes in particular) and bug fixes for Update.1 and packaged them in joyride for testing. Marco also tracked down two different issues with the datastore which was causing activities to not start. Fixes for both of them landed into Joyride. Finally, he changed the default Jabber server for Ship.2.

Reinier Herres worked working with Marco to build a new evince version for the Read activity, which will probably be available early next week. He also released a new Calculate with some bug-fixes.

Morgan Collett worked on Chat to fix scrolling issues—he made it not automatically scroll on new messages if you scrolled up to read the log and worked on copying URLs to the clipboard (#5080); he found some issues with clipboard handling in Sugar. We will land the Chat and Sugar changes when the Ship.2 dust settles. He also worked on the Presence Service: preforming lots of testing on Ship.2 and Joyride builds, testing recent fixes.

Memorize: Muriel Godoi reports that Memorize was launching under Rainbow, but wasn’t saving games in datastore; after some chats with Michael Stone, they realize that Memorize is creating new sub-folders inside their instance folder using tempfile library under permission 700 denying the access when trying to write into it. Changing the folder permission fixed that problem. Muriel also fixed the mime-type icon file location and added ogg support.

Muriel also reports that Food Force had some UI improvements, such as a message bar where contextualized educational messages to the player will be displayed. The code will be posted to his public_git next week.

10. Etoys: For Ship.2 release, Etoys team packaged a new version that has the progress made since Ship.1. Bert Freudenberg has been carefully working to adapt changes in Sugar while keeping the compatibility with old Sugar so that the latest work can be back ported. In this week, Yoshiki Ohshima and Bert improved the sharing experience and Takashi Yamamiya fixed a bug in script editing interface to make the version for Ship.2 be very comfortable. In the meantime, Scott Wallace took a pass on making an IDE for a traditional text file based programming system on Squeak, which may be useful for making an IDE for XO.

11. Localization: Xavi Alvarez and Sayamindu Dasgupta have finally put the GIT integration of the Translation Infrastructure (Pootle) in place in a fully working form. Translators can directly commit to GIT now via the Pootle web interface. We also have a new project in Pootle, called Update 1 (Core), which tracks the update-1 branch for a few core modules of the Sugar environment. From an average translation coverage of 23% at the beginning of the week, we have 33% average coverage now. Languages with more than 80% of Update 1 (Core) translated are:

French (100%)

Chinese (Taiwan) (100%)

German (96%)

Arabic (90%)

Polish (85%)

Spanish (84%)

Quite a few of the other languages are catching up quickly. A number of Indic language translation teams started work this week: Malayalam, Marathi, Punjabi, and Tamil. A Japanese project was also started this week. Waqas Toor and Salman Minhasreport that more than 85% of Urdu localization is completed.

Xavi and Sayamindu also managed to fix a few build breakages introduced by some issues in Pootle's PO generation code. Things should be running smoothly now (Sayamindu has also put in a logging framework in place that monitors the interaction between Pootle and GIT so that we can investigate potential problems easily later).

12. OLPC Pakistan: Waqas and Salman have initiated developing two e-Books and are busy working on an English to Urdu Glossary Project for OLPC. A community list for support in Pakistan is up and running (Please see http://groups.google.com/group/olpc-pakistan and visit the #olpc-pakistan IRC channel on irc.freenode.net).

13. System programming: Chris Ball worked on OHM early in the week, Ship.2 testing towards the end. Bernie Innocenti has been squashing the last few input, localization and configuration bugs. Mostly in olpc-utils and xkeyboard-config and finished moving the rest of the Xorg packages to Fedora's repository and now has no packages built locally. He also helped SJ Klein apply blanket changes all over the dictionary to fixlinks and encoding errors. And he did some transformations for the start pages. Bernie also finished building a geode-optimized package of glibc 2.7 that looks very promising, but still needs testing and started packaging X 1.4.99 from Fedora development, which seems interesting for the various EXA improvements. There is some PCI rework needed in amd_drv before we can start doing some benchmarking. He is hoping to offload the rest of this work to Stefano “aleph” Fedrigo, who in the past has been doing some neat X performance analysis for us.

Dennis Gilmore spent some time helping John Watlington and Michael Stone with some issues with the school server live image. He submitted a patch to upstream yum adding geode support and worked on a patch for rpm adding geode support should be done today or tomorrow. Dennis worked on some code to enable subscriptions to koji. This will let us import new builds into our own koji when we get it.

Andres Salomon worked on the xorg evdev driver (*cry*), setting up general geode testing infrastructure, some participation in the libertas nonsense (*cry*^2), and some dcon debugging.

14. Presence service: Guillaume Desmottes tested, modified and improve Dafydd Harries' patches for #4965; he did more ejbbard/Erlang investigations; reviewed Sjoerd Simons's Salut fixes; started to evaluate Openfire as alternative Jabber server; debugged and fixed a PEP problem in Gabble breaking sharing with Openfire (#5223); improved friends roster synchronization (#4965); fixed a Gabble bug when requestion lists channels (#5164); debugged and fixed a muc properties bug in Gabble breaking sharing with Openfire (#5224); and modified telepathy-python tubes examples to work with latest Salut.

Dafydd Harries worked on a more scalable XMPP protocol for activity management. Sjoerd Simons tested Salut for Ship.2 and fixed all outstanding Ship.2 issues it had.

15. Multiple-battery charger: Tooling has been ordered; first prototypes will be available at the end of December or early January. The PCB for the production system is done. The question is how many to build for our first run. The current plan is to build twenty-five, but this may be increased if there is more interest from trials.

Lilian Walter is progressing nicely on the battery charger firmware. She has been working on implementing a LiFePO battery charging algorithm this week. She has charged a battery, and so far only damaged a single battery.

16. Firmware: Mitch Bradley and Richard Smith have released Q2D05 with miscellaneous bug fixes for Ship.2. This contains EC firmware with the software workaround for most of the suspend/resume problems and the now controversial (?) blink-power-LED-on-suspend. Since suspend/resume is disabled for Ship.2, these changes will not be apparent to the user.

Wireless support from within OFW is still not totally robust. Mitch is unsure whether it is the WLAN firmware, the 1CC RF jamming, or an OFW driver problem. (Over the past week we have been unable to use WiFi channel 6 at 1CC due to constant, high level non-WiFi signal from an unknown source, the aforementioned jammer.)

17. Touchpad: Richard Smith is now pretty convinced that our touchpad problems are caused by the auto-calibration feature of the touchpad. The two problems—undersensitivity and jitteriness—are opposite results of a bad recalibrate. By forcing a calibrate to happen with the touchpad in various conditions he can recreate our touchpad problems.

“Go to a corner” and stay is caused by under-sensitivity. Duplicating this is fairly easy. Do the recalibrate (the “four-finger salute”) with as much of your thumb on the touchpad as you can, pressing quite hard.

“Jumpiness” is caused by over sensitivity. Duplicating this is bit harder. The best Richard has found is placing a large chunk of thick rubber on the touchpad while the unit is on battery power and then recalibrate.

A recalibration while the touchpad is in use causes under-sensitivity but we’re not sure how over-sensitivity happens the field. Nor do we yet understand why some laptops are so much worse than others. We are arranging a conference call with ALPS to discuss the issue. The only “fix” Richard proposes is to disable auto-calibration. It seems that auto-calibration can't ever be made safe without some method of insuring that the touchpad is free and clear for the recalibration. It is unclear whether we still need to auto-calibrate, or if this was only needed for the problems seen with the B2 build.

18. School Server: School server development has restarted. It was discovered that previously distributed installers will no longer work due to a reliance on a now missing Fedora server. The build system also needed repair but seems to be behaving again. A new build is being tested and will be released over the weekend. This build will have no new features but will contain the latest wireless mesh firmware and drivers.
