1. Taiwan: John Watlington, Mitch Bradley, and Richard Smith traveled to Quanta in Taiwan to work with Victor Chao, Arnold Kao and their team on the “bring up” of the pre-B3 boards. Jordan Crouse, Chris Ball, and Andres Salomon helped the team in Taiwan from afar (Colorado and Cambridge). Bottom line: it works.
1. São Paulo: Roseli de Deus Lopes and her team have been working with the teachers for a smooth introduction and work began with XOs in the school in this week. Naturally, even though there are only 100 laptops initially, word spread throughout the school and all the children and teachers are anxious to participate. David Cavallo met with the teachers for several days: the teachers and children will work in groups in inter-disciplinary projects, including a local-history project to grow and combine with all laptop schools.


2. São Paulo: Work began at a school on the periphery of the city with the XO this week. Naturally, every kid is totally excited. The only question anyone in the school, whether kid, teacher, administrator or parent, has is “When can I get one?” Teachers are staying up late to play with their machines and show the kids what they learned. Kids are teaching other kids reducing the burdens of class size and different levels. The school is transforming into a place of joy and excitement. They are beginning work on their wiki-based local-history project which they plan to collaborate with other schools.
2. Porto Alegre: Lea Fagundes and her team have been working with the XO in the Luciana de Abreu Elementary School for three weeks and already is having tremendous impact. The children of course are doing fantastic work and you see them moving around the school, taking pictures, working on projects, and truly engaged in their learning. Yesterday two teachers were unable to come to school due to family emergencies and the principal could not get substitutes; they dismissed the children of those classes early. For the first time in anyone's recollection, no one left when dismissed, preferring to stay and work with the laptops. The school had record attendance by parents for a meeting, with more than 10× the usual number attending. The teachers and children are ecstatic. The concrete example of chidlren, teachers, laptops and learning is changing the minds of doubters.


3. New “rabbit ears” arrived in Cambridge this week for our evaluation. Notably, these ears, when attached to a laptop, survive a five-foot drop test with direct impact on the ears in their extended (out) position. We will be testing them to higher drop heights in the coming weeks.
3. Rio de Janeiro: Michail Bletsas attended a two-day meeting organized by Rede Nacional de Ensino e Pesquisa (RNP), the organization that runs Brazil's academic network. The main theme of the meeting was digital inclusion and a people from the USP and Universidade Federal Fluminense (UFF) presented their first results from testing wireless connectivity on the XO laptop. Their conclusion: it works.


4. Sugar: This week saw numerous small fixes in the UI to improve the zoom experience. Marco Gritti, Tomeu Vizoso, and Eben Eliason have reached a consensus about how to handle controls in the UI, which is an important part of our developer story. Some of the comprises we have made won't give us the exact experience we are looking for, but they minimize risk to the project.
4. FISL8.0: Michail and Javier Cardona delivered back-to-back presentations on the various aspects of the OLPC mesh. Javier concluded with a nice audio-streaming demo via the mesh. Two XOs were streaming audio between them, their transmission power was limited to 1mW (from 60), so that the range between them was limited—about 40m with the rabbit ears down. One person went to the end of the lecture hall with one of the XOs and the audio stopped; another person went to the middle of the room with a third XO, which restored the audio flow.


5. Chat: A simple chat activity for the XO is coming together thanks to the joint efforts of Dan Williams and the Collabora team. Collabora is also putting together a video-call activity.
John Palmieri, Tomeu Vizoso, Marcelo Tosatti, David Cavallo, and Jim Gettys also attended the conference, which is the largest free software conference in the developing world (~5000 people pre-registered for the conference). Attendance at the OLPC booth was at times a crush and was always very busy.


6. Mesh portals: Dan Williams wrote up instructions on using B2s as mesh portals. Chris Ball tested and released the instructions in the wiki (See http://wiki.laptop.org/go/Establishing_a_Mesh_Portal).
5. Carla Gomez-Monroy, a former student of Walter's from the MIT Media Lab, will be helping us with the test school deployments. Carla spent several years working with the Schlumberger Excellence in Educational Development (SEED) Foundation, doing constructionist projects in schools in the developing world, including Nigeria.


7. Firmware: Chris and Mitch also tested OFW's wifi driver; it works. Having a wifi driver in the firmware allows us to build a script that can update our laptops with a button-press rather than carrying USB keys around.
6. Is XO the “greenest” laptop on the planet? This seems not to be just literal but also appears figurative: Mary Lou and Robert spent some time talking to various environmental agencies last week. Our low-power design, RoHS compliance, LED backlight (rather than mercury-containing CCFL), battery with 4× the standard battery lifetime, elimination of PVCs and Brominated flame retardants, etc., may actually spur environmentalists to create a new category for our laptop. More on this in the coming weeks.


8. Kernel: Andres worked with the Sparc and Power PC folks (upstream) on getting a device tree API that makes everyone happy. He also had his typical weekly adventure: he synched master up w/ Linus Tovalds; we now have 2.6.21-rc7 working.
7. B3: Pre-B3 motherboards will be made today (Saturday) at Quanta. The pre-B3 bring up in Taipei will commence on April 18 in Taipei with Richard Smith, John Watlington, Mitch Bradley, and David Woodhouse present.


9. Libraries: Christine Madsen has been working on visualizations of how different archives and libraries can work together to form an open library exchange. Justin Thorp from the Library of Congress's World Digital Library (WDL) project came to OLPC for two days of library discussions, and met with SJ Klein, Eben, Adam Brandi, Todd Kelsey, and Mel Chua. WDL is developing the next release of their interface and collection with target of the end of the summer.
8. New rubber ears: 30 sets of rubber bunny ears arrived Friday at OLPC; we will use them for drop testing to new heights early next week. Current testing shows our laptops survive a five-foot drop tests on the “open” ears.


10. Wikis: The Commonwealth of Learning (COL) hosted an annual conference about collaborative production of learning materials in Vancouver, Wednesday through Friday. Attendees included Merrick Schaefer of UNICEF, Murugan Pal of CK12, Erik Moeller of Wikimedia and Open Progress, and Joel Thierstein of Connexions; who are all working towards a global collection of CC-BY and locally-developed works. We set immediate goals for sharing materials across these projects; and identifying collections. COL offered broad support across their network of teachers and volunteers, especially in Nigeria. Erik and Brion Vibber from Wikimedia discussed how MediaWiki is planning to support asynchronous and offline editing; and 'live' off-line snapshots that people can edit. The Wikipedia 0.5 static snapshot was released last week; it can be downloaded via torrent. A child-friendly selection of topics is being developed; but still written at a high language level. A proper kid's-encyclopedia is still in the future.
9. Firmware/kernel: Mitch and Andres Salomon have succeeded in a complete boot off an SD card using a custom kernel and a few tweaks to OS Build 385. They are working on making it require fewer custom changes, so that booting off SD can be done routinely. Mitch and Richard worked on preparations for the LX processor (B3) board bring up next week. Mitch provided a version of the firmware to Quanta for initial debug.


11. Remote display: Zvi Devir documented a second method for remote display of an XO laptop in the wiki (See http://wiki.laptop.org/go/Remote_display). The trick is to install RealVNC and run x0vncserver on the XO. The remote computer, which can be connected to a video projector, runs a vncviewer that clones the XO display. (Note that this method will not yet workwhen the laptops are in mesh mode—we need to enable packet-forwarding on the School Server for the vnc connection. Until then, the XO must be used in infrastructure mode.)
10. User interface: Eben Eliason has developed a new tabbed toolbar system for Sugar that he has documented in the wiki. He also made yet another significant pass over the UI controls and will be meeting Marco Gritti and Tomeu Vizoso to get an API implemented for them. He has sketched mock-ups for our core activities (Write, Browser, etc.) using the new system and the team at Abiword has already begun implementing many of the new features.

Eben also specified a more detailed interaction for the clipboard, which will be consistent with current UI expectations while providing the additional features we want. The basic interaction is a clipboard stack, with the most recently copied item on top, which also acts as a push through queue when it fills up, dropping the bottom element from the stack when new items come in. And he prepared a refined “introductory sequence” for entering name, choosing colors, and taking a photo on first boot. Marco has this design and is working on implementation.

11. School server: Web caching is configured and running on the school server in the OLPC office in Cambridge. All XOs in the area running a current build are using it for network access.

12. From the community: Marc Maurer reports that his work on adding syntax coloring to AbiWord for the purposes of the develop activity is beginning to work. John Resig has been making progress on an eBook reader (See http://ejohn.org/apps/ebook/ for a live demo). Bruno Coudoin reports that GCompris is running on the XO. (GCompris is education software targeting young children that has been translated in more than 40 languages.) While it doesn't yet follow all of the design rules of Sugar, it is fun to see working. Ignatz Heinz at Avallain Learning is working on making an open-source version of their language-learning and literacy tools available for the XO. Google has just come out with a beta API to their new translation engine. Franz Och, one of their lead researchers, thinks it can be used for IM translation for the XO and would like to see this tested.
