A weekly update of One Laptop per Child, August 3, 2008
Learning
Thailand: OLPC held a five-day regional workshop in Bangkok, with more
than 50 participants from six countries. The goals of the workshop were
to:
* gain a deeper and more pragmatic familiarity with the ideas
about laptops and learning from both a micro scale (child-level)
and macro scale (national level)
* form next steps for laptop introduction in participating
countries
* strengthen network among countries in the region
The workshop went extremely well. Special highlights included sharing of
work in the rural areas in Thailand as exemplars of high-quality work,
and integration of school and community; storytelling with the XO by
Barbara Barry; computational uses of the XO by Roger Sipitakiat;
Nicholas?s talk on Thursday evening; and the Ban Samkha children?s
orchestra using their XOs to play traditional Thai music in TamTam.
Along with the Thais, delegations from Bangla Desh and Malaysia both
committed to purchase laptops.
Mongolia: The team returned on Monday afternoon from a two-week tour in
northern Mongolia, where they ran workshops for local teachers, kids and
parents. Together with the Mongolian core team, we worked in one city
center and two small villages, introducing the XO and constructionist
learning methodologies. The core team teachers designed and ran the last
workshop on their own. They came up with some wonderful and surprising
ideas, including a physical activity to teach angles and degrees to
students, which they then try in turtle art and etoys. It was amazing to
watch.
Tyler worked with the IT team to set up servers in two of the villages
that will be receiving laptops. Neither location had school
connectivity, but the network worked well.
Nicholas joined us in Khatgal, a small village in the Khuvsgul province
on our last day of training. A sheep was slaughtered and cooked in his
honor.
It was interesting to note the various dignitaries? motivations for
involvement in the project. The new head of ICTA, for example, was
inspired by the XO?s open source environment. He wants the students in
Mongolia to learn Linux and is working to get all government agencies
and higher institutes to cross over to a Linux platform.
The prime minister mentioned how moved he was to see children from a
poor district in UB receive their individual computers. He felt the
project not only will change education, but also what he called the
"mental" state of poor children who see their neighbors with the
luxuries of life while they go hungry.
Rwanda: The 20-member core team is ready to initiate teacher
development. The team discussed ways of introducing generative themes
for children to use for developing projects. There also was considerable
discussion on the issues of working with schools and communities.
Haiti: The team is currently wrapping up the pre-pilot Camp XO 2008 at
Ecole Nationale Republique du Chili. As we entered this final full week
we began to look at E-toys.
In our weekly meeting with the teachers, T1 teachers asked what type of
assistance they would receive to better understand integration of the
XOs into their curriculum. They are naturally concerned because the XO
is such a novel tool, so different from their previous experience. The
team has been trying to explain to the teachers that their goal
shouldn't be to know the technology better than the students, but to
seek ways to utilize the tools to further learning objectives and
enhance the overall learning experience.
In the tech team meeting, we identified local sources of solar panels
for each school that may need them. It is still difficult to determine
which schools will receive decent internet connection because of Haiti's
mountainous terrain.
Technology
Robert, Chuck, Kim, Michail, Richard Smith and Darah met to discuss and
understand upcoming hardware changes and their business implications.
OLPC is planning to migrate from Marvell's 88W8388 wireless chip to the
88W8682. The newer chip offers a 50% improvement in power consumption
and has more onboard memory which will allow us to implement better mesh
algorithms. Additionally, we are preparing a transition to a new
supplier and a single-mode touchpad. Both changes are expected in mid-Q1
2009.
Networking
1. Mitch Bradley made further progress on the Windows dual-boot,
resolving
issues with ACPI support for lid switch handling and battery/AC status
reporting. The only remaining issue at this point is chopped-up text
during pre-OS chkdsk and blue screen of death displays. He released a
new OFW image with an important bug fix for booting in the face of a
certain kind of JFFS2 inconsistency; fixed some bugs related to the use
of certain SD cards; and mapped the behavior of the Geode GPIO event
detection circuit to assist in the resolution of suspend/resume issues.
2. Deepak Saxena spent far, far too much time trying to backport the
Libertas
thinmac/host mode driver into our 2.6.25 kernel, so we can build it into
our released kernel RPMs. He determined that backporting requires
bringing in a large stack of changes to the core 802.11 kernel bits.
This was very painful. Thankfully, Luis Cabo Cobo at Cozybit pointed him
to a simpler way of doing it. Deepak now has the driver working with our
Joyride kernels.
3. Thanks to Mitch?s analysis of the CS5536 (#5703), Deepak
re-implemented the lid-detect logic in the kernel and, as Chris Ball
requested (#7536), added proper handling of the lid when the XO is
suspended.
4. Ricardo worked on active antenna repogramming documentation, and Bill
McCormick from Nortel looked into one of the most persistent UI/Network
Manager bugs, which often prevents XOs from re-associating with
encrypted wireless networks.
5. Marvell brought us a development system for their "Kirkwood" SoC CPUs
running Fedora Core 8. It currently sits in Jim's office, where people
may play with it. The system will slowly make its way across the
continent to Deepak.
Software Development
6. Chris Ball finalized the "failsafe" code for booting with a full
NAND. As of build update.1-709, the laptop will interrupt boot when the
NAND is full, then warn users in English and Spanish that they will lose
data and should first back up their laptop. After confirmation, the
machine also will free up enough space to boot by deleting large
datastore objects or activities.
7. Sayamindu Dasgupta fixed the Mongolian keyboard layout problems and
made some progress on the Dari keyboard issue as well as the Amharic
Compose key problems. In order to handle complex scripts like Chinese,
Japanese, and Korean, he has started to evaluate a possible switch to
SCIM (Smart Common Input Method: http://www.scim-im.org/) for the next
major OLPC release. Savamindu also created a new getting started page
for Pootle
administrators:http://wiki.laptop.org/go/Pootle/AdministrationQuickStart.
8. Erik Garrison worked with David Woodhouse to verify that test
failures encountered while LZO-compressing partition images were
spurious and non-fatal. Erik also conversed with Mitch about the process
of building and installing a partitioned OS image on the XO.
9. Guillaume Desmottes continued work on Gadget Gabble, improving
integration in Sugar by implementing a simple wrapper around views
objects, making them easier to use with Sugar. Guillaume also improved
presence management.
10. Faisal Anwar added new sections about the clipboard to the Sugar
Almanac, and is engaging the community to finalize new sections on the
presence service.
We encourage you to peruse and contribute to the almanac, available
athttp://wiki.laptop.org/go/Sugar_Almanac.
11. Martin Langhoff released build OLPC_XS_165 of the school server
(XS), which is our xs-0.3 "release candidate.? Thanks to Bryan Berry and
David van Assche, who have provided excellent notes on installation
steps and shortcomings.
Community
12. At Wikimania 2008, SJ Klein presented recent offline wiki efforts on
the XO, including a version of the Arabic Wikipedia which was being
finished that week with help from Bassem Jarkas and moulin.org. Many
groups in attendance wanted to start OLPC-related projects, particularly
extending access to wiki-repositories to offline communities.
13. Adam Hyde and Anne Gentle are organizing a Sugar documentation
sprint for the last week in August. Details to be finalized soon. Seth
Woodworth wrote up an overview of the current docs projects.

Activities
14. Morgan Collett fixed some Chat bugs in release Chat-44.
15. Daniel Drake fixed the Read activity, worked with Victor Lazzarini
to fix a csound bug that was breaking TamTam, and worked with TamTam
developers to produce new releases.
16. Mohit Taneja and Deepank Gupta now have a working game for Food
Force 2, suitable for an alpha. It is being repackaged as an .xo
bundle:http://code.google.com/p/foodforce/

Support/Sysadmin
20. Adam Holt reports that the 100th volunteer for the Support Gang
joined this week! The tickets associated with last year's Give One Get
One are tailing off as we begin planning for the 2009 G1G1. Going
forward, the focus for the Support Gang is on technical issues and
helping people use their laptops rather than fielding fulfillment
questions.
Some members of the Support Gang are helping out with the upcoming
documentation sprint. Adam has identified wifi access points that have
been reported as problems. We will purchase these to add to our test
environment. He and Kim are working on the details and systems to put in
place to help repair centers get spare parts and track their problem
reports.
21. SJ Klein and Henry Edward Hardy have updated teamwiki to v. 1.13 and
enabled semantic mediawiki. This will facilitate tagging and other Web
2.0 features.

A weekly update of One Laptop per Child August 12, 2008
India: Nicholas and David Cavallo spent Monday in Mumbai with Satish
Jha, president of OLPC India, under the aegis of Reliance. The day?s
events included a national video conference, a meeting with Johny
Joseph, chief secretary of
the state of Maharashtra and a lecture to the Asia Society. Maharashtra
is huge, with 100 million people, or about 10 percent of India?s total
population.
On Tuesday, Reliance and the Digital Bridge Foundation organized a
one-day workshop for teachers, laptop donees and volunteers. The goal
was to provide a basic understanding of the XO and the OLPC approach to
learning in a saturated deployment. The program motivated many attendees
to launch new XO deployments and also to improve existing XO sites in
India.
On Wednesday a similar workshop was held in Goa, organized by Dr. Rita
Paes, the director of a local teachers? college, and sponsored by the
Goa Chamber of Commerce. Just as in Mumbai, more people and sites were
engaged. With the support of local business and the teachers? college,
they will pursue a statewide deployment initiative for Goa, which
already is advanced in providing connectivity and computers to schools.
Nicholas, David, Satish, Manusheel Gupta and the Reliance team also
visited the remote Vastishala Khairat-Dhangarvada School, 81 km from
Mumbai, where Carla G?mez Monroy deployed XOs some months ago. The
children sang for their visitors, and presented them with red roses.
Sandeep Surve, Khairat?s single teacher, believes deeply in the OLPC
program. ?Education through XOs has completely solved educational
problems like child absenteeism, parent-teacher interaction, and lack of
interest towards education,? he said. ?Children relish coming to school
every day, and their interest towards education has risen dramatically.?
Learning
Haiti: It was a busy week at OLPC Haiti as the team wrapped up the
summer camp at Republique de Chili. Every major television and radio
station came out as well as several government officials, including the
ministers of education and communication and public works. One of the
second graders showed off her problem-solving skills to the minister of
education. When her computer lost power as she was attempting to
demonstrate her very impressive work in E-toys, the student ran to
charge her laptop while a reporter held the minister's attention. Within
five minutes she returned with a gentle tug on the minister?s sleeve,
excited and determined to display her work.
http://www.youtube.com/watch?v=9T1hLfcy_xI
At the end of camp, the teachers wrote reports on their personal XOs for
the Ministry of Education. They were uniformly enthusiastic about the
program, and training team, and impressed with how the kids easily
worked with one another. They thought the training period was too short,
that the students? parents should have been more involved and they asked
for more content.
The team spent the rest of the week working on the operations manual.
This was both a content-driven task and a team-building exercise, led by
national coordinator Guy-Serge Pompilus, and organized into three parts
- administration, technology and pedagogy.
The translation of Pootle is now 67 percent complete, and the core
system is 97 percent finished. Translation of the Getting Started OLPC
guide is in progress, and the team is double-checking the current
translation because many volunteers did not use Haitian kryol. They also
have started to translate Scratch, as well as finish Etoys.
Here is an FAQ for the translation
http://olpchaiti.org/interne/faq_traduction.php
Rwanda: This week saw the first teachers? development workshop,
conducted from Wednesday to Sunday in the Regional ICT Research and
Training Center. Sixty-five teachers participated from the three launch
schools in the districts of Kagugu, Nonki and Rwamagana.
The core team involved the teachers in simple XO activities, such as
using the camera, text editor, and Speak. They explored mobility by
taking activities outside the classroom. The main goal was to break any
initial fear among the teachers, and to make them comfortable with
exploring the laptop by themselves. They also used more complex tools
such as Scratch, doing basic programming to create short dialogs in a
very playful way.
The experience was valuable to the core team, too, for they will be the
ones to provide long-term support as the deployment expands to more
schools. The OLPC team feels they are gaining broader acceptance from
other ministries and organizations. The national coordinator, the
primary participants, the core team, and the OLPC team continue to
develop a strong collaboration. People are very enthusiastic.
Technology
China: The Summer Olympics aren?t the only big news coming out of
Beijing. Nortel Networks is setting up a research and development center
in the capital to develop localized software activities and content for
One Laptop per Child in China. Anthony Wong, Manu Gupta, Robert and
Darah Tappitake are working with Eric Lauzon, CIO of Nortel Asia and
Teresa Oon, IT and Business Operations head to develop a framework for
this project.
Networking
1. Michail, Ricardo, Kim, Javier, Ronak Chokshi from Marvell and all the
Nortel people involved with OLPC conferred in Cambridge on how to
advance Nortel's
involvement with OLPC's mesh. It was decided that for now Nortel would
have the strongest positive impact by assisting Ricardo with his MAD ?
Mesh Adaptation Daemon - effort and helping to fine tune the wireless
driver. MAD is a user space process that watches mesh statistics and
dynamically tunes operating parameters like path expiration times and
allowable transmit rates.
In the next few months, Marvell will release the SDK for the 8682 (the
wireless chip that will replace our current 8388 in early 2009), and we
hope that the company will be able to have some engineering resources
available to work on firmware-level code for the wireless chip.
Javier will start investigating real-world performance of mesh multicast
schemes by implementing them on top of the open802.11s software stack.
We expect to have such functionality available on the 8682.
2. Mitch Bradley fixed an OFW2 bug which made "text mode" Windows
screens look garbled (choppy blue screen of death, anybody? ;-). He has
completed the first phase of the Windows-support work. The second phase
involves support for booting Windows from the internal flash.
3. Deepak Saxena worked primarily on tracking down and fixing an audio
quality regression issue (#7603) in the 8.2 release. Deepak also started
setting up new kernel repositories as outlined
inhttp://lists.laptop.org/private/techteam/2008-June/000500.html.
Releases/Deployments:
4. Greg Smith, with help from Francesca Slade, created a new page to
track location as well as the hardware and software status of
deployments. See: http://wiki.laptop.org/go/Deployments
5. Greg also finalized release 8.1.1 (build 708). Read the release notes
carefully as this release is not for everyone. Do not use it with an SD
Card and be prepared to re-install activities if upgrading from a build
earlier than 703. See:http://wiki.laptop.org/go/Release_Notes/8.1.1
6. Kim is working with a number of people to get the 8.2.1 (build 710)
finalized. For details of fixes in this release,
see:http://wiki.laptop.org/go/OLPC_SW-ECO_6
7. Guillaume Desmottes spent some time this week with Greg, Michael
Stone, Dafydd Harries and Morgan Collett to triage and prioritize the
collaboration tickets.
8. Greg, Kim, Jim Gettys, and Michael are part of a regular team that is
doing daily triage of new bugs for 8.2.0. We will be starting change
control and choosing just the bug fixes that we want in the next few
days in order to get a ship date for this release.
Software Development:
9. Jim worked with Greg Dekoenigsberg and Sebastian Dziallas to explore
the feasibility of an easy-to-install "conventional" Fedora distribution
(these are called spins) for the OLPC. Preliminary study suggests this
is simple to do. While considerably larger than the OLPC distribution,
it would be small enough to install easily, unless support for Eastern
languages is necessary.
10. C. Scott Ananian continued integration and upgrade work, releasing
new versions of Sugar-update-control and OLPC-update. He also worked
with Martin Dengler to help diagnose and fix a bug which broke
networking in Joyride builds. Prodded by Chris Ball's frustration at the
delays involved in getting new code into a build, he took apart the
joyride package collection system and stared hard at all its components
until he found a tricky bug in an implementation of __contains__ that
caused it to invoke itself 33 million times over the course of a short
run (!). Fixing this bug (and performing a few other performance
improvements for good measure) sped up package collection from several
hours toabout 10 minutes. As a result, the joyride build process is now
started hourly, instead of every three hours, reducing the testing cycle
time.
Scott also investigated the space penalty imposed by adding an XFCE
environment to our basic build. Initial results (on the 'faster' branch)
show a 50M space penalty, even without adding applications for use in
this environment.
11. Erik Garrison worked on implementation of partitioning support, plus
building build-side tools to integrate with Open Firmware's partition
update system.
12. Sayamindu Dasgupta spent most of this week trying to coordinate with
the translators on pushing in translations for the next release. He also
wrote patches to fix the Dari keyboard issue and to partially resolve
the Amharic Compose sequence issue.
Sayamindu spent most of this week trying to coordinate with the
translators on pushing in translations for the Sucrose 0.82 release. At
the time of the Sucrose release, the following languages have more than
80% translations done for Glucose and Fructose modules (and a few other
extra activities).

Note that this does not include Etoys translations.
13.Chris Ball worked on several power manager features which are present
in the new weekly build (joyride-2263). The "sleep" functionality on lid
close or power button press is now more robust, will reliably wake onlid
open, and saves battery life by no longer having temporary wakeupsfor
deciding whether to wake up fully. The "olpc-hardware-manager"script has
now been retired, with all of its functionality taken overby OHM, which
saves us 5-10MB of RAM.
14. Michael wrote about OLPC's "security" software subsystem, updated
the rainbow and OLPC-utils packages and scheduled a meeting with the
Boston Linux and Unix User Group (blu.org) for the night of August 20th.
15. Eben Eliason created some new mockups (to be posted shortly) for
Creative Commons licensing integration in the Journal, and for a Speech
device which will provide text-to-speech throughout Sugar.
More Software Activities:
16. Deepank Gupta made tremendous progress with Mohit Taneja on the Food
Force project. www.code.google.com/p/foodforce). The efficiency of the
project has increased dramatically with the development work on the
following features:
1. Optimization of the collision detection algorithm
2. The frame rate has been adjusted to make a better experience for the
children in the shared mode
3. The changed sprites in a frame are only displayed instead of the
game canvas.
A number of reported issues have been fixed, too:
1. Unhandled exceptions
2. Increasing the minimum zoom level
3. UI issues on the movement of villagers near the rural
facilities.
Integration of texts and creation of a Sugarized package will be
completed during the coming week. The project will be released for
testing and feedback on August 15th.
Spreadsheet Activity:
17. Manu and K.S. Preeti have been building use-case scenarios to check
the performance of the spreadsheet activity.
http://lists.laptop.org/listinfo/socialcalc
Educational Toolkit:
18. The code in the ?model? module was re-factored and the user
interface of the project now supports better interaction tools. Ross is
about to complete the performance testing of the connection module.
http://dev.laptop.org/git/activities/Educational_toolkit)
School Server (XS):
19. Martin Langhoff reports that the "xs-rsync" package is available,
which allows the XO to back up its data to the XS. In general terms, it
allows publishing of resources on the XS via rsync, with special support
for XO update images. More documentation
athttp://wiki.laptop.org/go/XS-rsync. Scott has applied a small patch to
OLPC-update that adds support for a server parameter.
A mechanism for triggering scripts when you insert a USB disks intoa XS
is ready. This allows us to deploy content and management scriptsvia USB
disks. Policy and guidelines on how to use this, includingsecurity, are
taking shape. The mechanism uses a ported version ofusbmount - early
documentation athttp://wiki.laptop.org/go/XS_Automount_triggers
Douglas Bagnall started working on the school server this week. He
tackled some bugs in the idmgr (#7606 and #7653), but most of the week
really devoted to familiarization with Fedora and the specifics of
theXS. For a while he was befuddled by a faulty network card, but
byFriday he was back in control and enjoying himself.
20. Thanks to Axel Thimm we have a fixed fakeroot on the XS, and one
less race condition. Jerry Vonau is exploring the Fedora 9 port for the
XS, looking at our custom network scripts, xs-config and
livecd/installcd build infrastructure.
Community/Activities:
21. Alex Leventhol created a poster about his work on X2O and finished a
working framework that the MIT gamelab programmers got quite excited
about on Wednesday.
22. Francesca finished her work on making Semantic MEdiaWiki accessible
to other wiki editors, which will greatly help us organize our data-rich
categories.
23. There are a number of groups interested in getting laptops for
development and test purposes such as SFXO, Fedora, and Ceibal in
Uruguay. SJ Klein is working with them through the contributor's
program.
Testing:
24. Charlie Murphy, Francesca, Seth Woodworth and SJ put finishing
touches on the design of the test case writing/reporting system. They
were helped by S. Page, Asheesh, Diane Serley, Michael and Henry Edward
Hardy. The first test cases and some results can be seen
here:http://wiki.laptop.org/go/Test_cases_8.2.0
25. Greg and Michael have been helping get the word out for others to
help test: http://wiki.laptop.org/go/Friends_in_testing. Martin Langhoff
is coordinating a Wellington, NZ smoketests-and-brunch morning with
various Wellington hackers.
Support/SysAdmin:
26. Erik and Kim are working with Hernan Pachas to prepare the next
15,000 laptops to be upgraded and activated. They will be supplying a
developer to take over the maintenance of their scanning code software.
They also are updating the content in this next upgrade. Erik has also
been involved in Uruguay's problems with the Nand-full issue. He is
helping them with thoughts on how to integrate our solution with their
code base.
27. Kim finalized the Letter of Intent for allowing some ecommerce
websites to sell OLPC spare parts. We hope to take the first orders in
the next week or so.
28. Greg Dekoenigsberg of Fedora and Red Hat and Henry are exploring
utilization of community resources to enhance our systems administration
capabilities. A mailing list,olpc-sysadmin [ at ] laptop [ dot ] org, has been
established to facilitate this collaborative effort.
29. Mike Lee, a volunteer and active long-time friend to OLPC and the
Media Lab, came by CC100. He is debugging a periscope for the XO so that
you can look at the computer screen to see the scene you want to record.
It is progressing but too still not yet ready for release.
30. Jack has been fixing the TurtleArt intro. Since this is his last
week at OLPC he is working on getting everything uploaded to the wiki.
Currently the TurtleArt intro is on the wiki as a book. Cynthia also
uploaded a really nice paper by Marvin Minsky on kids and computers.
31. Brian Silverman and Artemis Papert have made three books using
TurtleArt and describing the scripts as Logo procedures. Cynthia is now
converting the procedures to TurtleArt scripts. Some pages of the
TurtleArt books are viewable online at
http://www.blurb.com/bookstore/detail/318689
32. Morgan Collett assisted with triaging the collaboration tickets
for8.2.0. He released Chat-45 for the Sucrose 0.82 release. He started
ona version of Read using Cerebro as a back end instead of the existing
collaboration framework, as a test case and for performance comparison.
He also started contacting activity authors of older activities to find
out if they can be updated or if they need a new maintainer, and to
survey the needs of activity authors.
33. Marco Pesenti Gritti released Sucrose 0.82 and packaged it for
joyride, in collaboration with Simon Schampijer. He fixed a critical bug
which was causing the second instance of some activities to crash. He
looked into the Arabic issues, landed some of the patches and suggested
a solution for the remaining problem with icons direction.
34. OLPC intern Francesca Slade and community volunteers have done
excellent work in implementing our new semantic wiki capabilities for
testing, deployment reporting, and activity tracking. Volunteers S.
Page, Asheesh, and Diane Serley, intern Seth Woodworth and OLPC'ers SJ
Klein, Michael Stone and Henry Edward Hardy contributed.
35. Richard Smith continued to work on the EC command timeouts. Most of
the week was spent testing the new "fastpath" command code. Most EC
commands are now processed in under 3ms with periodic spikes up into the
9ms range. The spikes are the result of the EC code doing other tasks
before rolling around to processing the command. If necessary these
spikes can probably be eliminated by identifying what parts of the EC
code are taking the longest time to process and either reducing that
processing time or interleaving command code processing inside those
routines. Using multiple machines in his suspend/resume test bed he has
run over 100k cycles without seeing a timeout. While Richard won't claim
that the original problem is fixed because the root cause of the
timeouts was never identified he's moving on to other things. Richard is
going to continue to run his suspend/resume testbed and watch for a
re-occurrence of timeouts.
The thermal issues that we plaguing the multi-battery charger now appear
to be solved. Thermal tests on the 2 existing prototypes by both
Flextronics and RCAL are passing. RCAL is now going to perform a
destructive test to determine the max operating temp of the unit.
Prosoyo shipping 10 units from the chassis they have built and RCAL will
assemble these into complete chargers. The remaining 40 chassis will be
shipped after they are completed. The 10 units will be used for further
testing and software development. At least one of these units
(and probably 2) will be sent to the OLPC offices.
36. In between continuing ad-hoc testing of joyride builds, Paul Fox
managed to get the EC code booting (built under sdcc) with enough
stability to bring the laptop up. This sped up the debug cycle
dramatically, since the SPI flash can now be reprogrammed in-place.
37. Michael Stone coordinated volunteer testing by broadcasting and
amplifying the request to help test joyride-2263 on the Wiki, forum, and
on many mailing lists. He also ran meetings, created trac reports,
produced some builds for release 8.1.2 (ECO-6), wrote about OLPC's
"security" software subsystem, updated the rainbow and olpc-utils
packages, scheduled a meeting with the Boston Linux and Unix User Group
(blu.org) for the night of August 20th.
38. Walter's most recent two Sugar digests can be found at:

>From the Field
Pakistan: An advertisement Habib Khan ran in the Punjab press reaped
these responses: Eighty-two callers inquired how to purchase one or two
XOs for their children; Two NGOs said they wanted to provide about 150
XOs each to their schools; Almost everyone asked about a warranty, and
wanted to know about machine repairs.
The OLPC user?s manual in Pashto and Dari for Afghanistan is finished,
thanks to the help of two Afghan volunteers, Usman Mansur Ansari and
Sohaib Ebtihaj Obaidi, both graduate students at IIU Islamabad. The

Telecom,a popular IT magazine in Pakistan, visited the OLPC office to
learn about OLPC, and to interview Habib for a forthcoming issue.
The Islamabad office also added three more books to their school bag
activity, as well as Units Five and Six to their Learn English content
bundle. http://wiki.laptop.org/go/OLPC_Pakistan_Activities
Localization of Urdu received a lot of feedback from the children and
teachers. The completed translation reviews can be seen

Habib reports:
?Our prized school for slum children has finally found a small house
where it re-opens later this month. The other school, Mahfooz Shaheed in
Korall valley, also re-opens this month after their summer vacation. We
are planning to test new activities.
?We have performed tests on OLPC build 703 so that we can upgrade the
builds at our pilot project sites soon after the schools reopen. Some
findings:
* The XO battery charge lasts 3.5 hours, but decreases when the
laptop is used for activities such as TurtleArt and E-toys.
* The journal slows down when entries rise above 150.
* We have selected two fonts that work perfectly with Urdu. Like
Arabic, Urdu script is written from right to left. Characters
tend to join in similar fashion to make word. Only Nafees, Web
Naksh, and Tahoma have complete Urdu character sets which work
with Sugar. Other fonts are not compatible with the character
set of Urdu: http://wiki.laptop.org/go/Urdu_Screenshots We are
going to randomly deploy both fonts, then test them with
children at our pilot sites to gauge their comfort levels with
each.?
And in Other News?
The Times of London has published a provocative article entitled, ?Why
Microsoft and Intel Tried to Kill the XO $100 Laptop.?
