; David Cavallo : ha formado un equipo de aprendizaje que trabajará con los paises para que desarrollen sus propios equipos de aprendizaje. El objetivo es ayudar para que cada país desarrolle un mayor entendimiento y prácticas más enriquecedoras en el uso de las laptops para el aprendizaje. Realizaremos talleres en la OLPC todos los meses, trabajaremos en los países, e internacionalmente. Los primeros talleres en países serán en Etiopía, Ghana, Rwanda y Nigeria durante el mes de octubre.

1. David Cavallo has formed a learning team that will work with countries to develop their own learning teams. The goal is to help each country develop a deeper understanding and richer practice in using laptops for learning. We will hold workshops at OLPC each month, work in countries, and collaborate internationally. The first workshops in countries will be in Ethiopia, Ghana, Rwanda and Nigeria during October.
1. Shanghai: Mary Lou Jepsen, John Watlington, Richard Smith, and David Woodhouse joined the extensive team from Quanta in Shanghai for the B4 build. 2000 laptops are scheduled to be built by the end of Monday, more than half are already built. Things went so well that the build was started early, leaving the OLPC team ample time to work other components of the OLPC ecosystem: school server, multi-battery charger, active antennae, and WiFi repeaters. The B4 yield (so far) is approximately 99%—up substantially from previous builds. Improvements in B4 include: texture on the upper handle bar; increased hinge tilt; elimination of the hinge “squeak”; rabbit ears that click into place when put into the down position; elimination of a slight camera vignetting by the bezel; minor modifications to the motherboard; etc.

2. Schedule: We still have not gotten to a full code freeze as there are too many open critical bugs. If you have blocking or high-priority bugs open for Trial-3, please help us by analyzing the work load, making a suggestion for a work-around or how to document the issue, and setting the bug to “untriaged” so that the triage team will review it. Please check with Jim Gettys or Kim Quirk before checking in any code changes.
2. EC: Richard Smith and David Woodhouse have moved the kernel battery driver over to new embedded controller (EC) protocol. In the process, David had some some suggestions that Richard will be folding back into the EC code. Meanwhile, Richard has flushed out a few minor EC bugs and submitted fixes back to Quanta.

; Prueba : Alex Latham actualizó las notas de configuración de pruebas en el wiki para considerar los escenarios de configuración de acceso a redes: dos laptops bajo un árbol; una laptop conectada a un punto de acceso; y una latpop conectada a una malla del servidor escolar. También hay notas adicionales sobre configuraciones y planes de pruebas para la localización (ver [[Test issues]]. Alex Khitrick y Yani Galanis, se han "unido" al equipo de pruebas durante la semana para ayudar con la ejecución de los casos de pruebas, ''debuggeo'' y tomar notas de los ''bugs''.

3. Test: Alex Latham updated the test configuration notes in the wiki to address network-access configuration scenarios: two laptops under a tree; laptop connected to an access point; and laptop connected to a school server mesh. There are also some additional configuration notes and test plans for localization (See [[Test_issues]]). Alex Khitrick and Yani Galanis have both “joined” the test team this week to help with executing test cases, debugging, and writing up bugs.
3. School server: Scott Ananian, John Watlington, and Dan Margo worked on school-server configuration management. The process—a combination of RedHat's RPM system and a version-control system—will allow system updates of OLPC specific configuration files while preserving local configuration modifications.

; Hardware : El equipo de hardware (que incluye gente de Quanta y AMD) pasaron la semana tratando de rastrear algunos de los problemas pendientes de suspender/retomar. Hemos llegado al punto en el cual muchas laptops han estado corriendo durante cientos de miles de ciclos sin ''crashes'', aunque todavía pueden ocurrir ''crashes'' ocasionales (y algunas laptops son más suceptibles que otras). Ninguna otra laptop se le acerca; pero tampoco tienen nuestro ambicioso objetivo de suspender entre lectura de páginas (o hasta entre pulsaciones de teclas), potencialmente llegando a los miles de páginas por día.
; Firmware :
: El limitado margen de ruido en la línea de +3.3V que alimenta la mayoría de las comunicaciones inter-chips (y la WLAN) de la laptop ha sido la gran sorpresa. Una sorpresa aún mayor fue que dicho margen estaba críticamente relacionado con el voltaje de la batería! Cuando la batería estaba baja, nuestra alimentación de 3.3V estaba cayendo por debajo de 3.15V, debido a una alimentación insuficiente de un transistor usado para apagar el +3.3V durante la suspensión.
: John Watlington y Quanta han propusto una solución que está siendo probada. Esperamos que mejorando esto podamos cerrar definitivamente el ''bug'' de "imposible retomar usando el botón de encendido o inalámbrico" (ver http://dev.laptop.org/ticket/1835) &mdash; que de hecho eran dos problemas diferentes uno de los cuales fue resuelto la semana pasada&mdash;y tenemos razones para pensar que era en parte responsable del ''bug'' de "fallas de inicialización del USB inalámbrico al suspender/retomar" (ver http://dev.laptop.org/ticket/1752 y http://dev.laptop.org/ticket/2621).
: Nota: cualquiera trabajando sobre problemas de suspender / retomar debe mantener sus máquinas enchufadas hasta que esté resuelto apropiadamente.
: Chris Ball realizó pruebas nocturnas en varios de los cambios de hardware propuestos. El ''bug'' de retomar la inalámbrica están ocurriendo con menos frecuencia, tanto así como para que otros ''bugs'' del kernel sobre retomar tomen mayor prioridad (ver http://dev.laptop.org/ticket/3477 y http://dev.laptop.org/ticket/3479).

4. Hardware: The hardware team (which includes people from Quanta and AMD) spent this week trying to track down some of the remaining problems with suspend/resume. We have reached a point where many laptops are running for hundreds of thousands of cycles without crashing, but occasional crashes still occur (and some laptops are more susceptible than others.) No other laptop comes close; but neither do they have our ambition to suspending between each page read (or maybe even suspending between keystrokes), with potentially thousands of page views/day.
4. Firmware: Mitch Bradley started work on school-server firmware and integrated the cryptographic code into Open Firmware needed for our Bitfrost security system. Lilian Walter modified the TCP layer to support IPv6. She can successfully “finger” and “telnet” to her Fedora Core 7 PC.

The low noise margin of the +3.3V line that powers most inter-chip communication (and the WLAN) on the laptop was the big surprise. An even bigger surprise was that the margin was critically dependent on battery voltage! When the battery was low, our 3.3V supply was dropping to below 3.15V, due to insufficiently turning on the transistor used to switch +3.3V off during suspend.

; Sistema :
{{ Translated text |
5. System: Chris Ball wrote a script to backup and restore user data from a USB disk during OS build upgrades, so that laptops can be upgraded to newer builds without losing data. The script is still being tested, since there are some “corner cases” to deal with—for example, some old Sugar configuration files causes newer versions of Sugar to crash at startup.


John Watlington and Quanta have a proposed solution which is being tested. We hope that improving this will close out the “unable to resume via power button or wireless” bug completely (See http://dev.laptop.org/ticket/1835) — it was actually two distinct problems, one of which was fixed last week—and we have reason to hope that it might be at least partially responsible for the “USB wireless suspend/resume failure at setup phase” bugs (See http://dev.laptop.org/ticket/1752 and http://dev.laptop.org/ticket/2621).
Andres Salomon did some merging (we are up to 2.6.22-rc5 on master) and created a vserver branch and added the vserver patch (See http://dev.laptop.org/~dilinger/vserver). He also did some bug triaging and worked on merging in the persistence-USB code from Andrew Morton's -mm tree.


Note: anyone working on a suspend/resume problem should keep their machine plugged into line power until it has been properly modified.
Scott Ananian spend the week writing kernel patches for DNS autoconfiguration over Ipv6. The kernel functionality is now working; Scott still has to patch this into “userland” properly (glibc and/or network manager), and get the patches shipped and accepted upstream. In the process, Scott fixed another bug in the router advertisement daemon (radvd) this week, added some kernel documentation, and found a few minor bugs in the kernel to fix.


Chris Ball ran overnight tests on many of the proposed hardware changes. The wireless resume bugs are now occurring rarely enough to have taken a backseat to other kernel bugs related to resume (See http://dev.laptop.org/ticket/3477 and http://dev.laptop.org/ticket/3479).
Bernardo Innocenti has been looking into Geode optimizations of glibc—Rob Savoye had developed some optimizations working from code originally written by John Zulauf.

John Palmieri has been working on the Fedora 7 move. Most of the packages we need to worry about now in place. We will be pulling our builds together from three different repository: the F7/OLPC repository, dilinger's (Andres’s) kernel repository, and a temporary repository that exists until we have emergency builds and until Etoys can be put into the Fedora repositories.

Alex Larsson, who is on loan from the Red Hat desktop team, has been working on a new live-update system for the XO. He posted comments for review to the devel mailing list earlier this week and has since then been working on an implementation. He now has code that can update between image versions, including reverting back to older versions of an image. He also has working code that can detect an update that is available from another laptop on the mesh, and can download it locally instead of going to a central server over a potentially slow, high-latency, high-cost network. Finally, he has code that will host an update on a laptop and publish it on the mesh.
; Firmware : Mitch Bradley publicó Q2C27, la versión del firmware planeada para el Trial-3. Incluye la capacidad de inicio-seguro (pero también puede arranar en modo no-seguro). Ha sido probado sobre sistemas B1, B2-1, pre-B3, B3 y B4. No lo usen sobre placas pre-B1&mdash;ya que las inutilizará (''brick'') debido a los cambios realizados en el microcódgo del controlador embarcado (CE). Notese también que no funcionará en placas Test-A debido a que el soporte de dichas placas ha sido eliminado del microcódigo.

5. Firmware: Mitch Bradley released Q2C27, the firmware released planned for Trial-3. It includes secure boot capability (but can also boot in a non-secure fashion). It has been tested on B1, B2-1, pre-B3, B3, and B4 systems. Do not use it on pre-B1 boards—it will brick them because of changes to the embedded controller (EC) microcode. Also note that it does not work on A-Test boards as support for A-Test has been eliminated from the EC microcode.
6. X11: The X11 update is only missing a few package rebuilds and a few new RPMs. The new keyboard descriptions are ready to go. Bernardo, Miles Grimshaw, and Walter Bender have been collecting more localized keyboards (Turkish, Ethiopic) and modularizing our changes to make them acceptable for upstream. Bernardo has gotten a positive response from Sergey Udaltsov regarding our changes and is waiting for final approval.

; Código CE : Richard Smith refactorizó la forma en que el CE realiza la inicialización de modo tal que se reinicie automáticamente después de un reflash. Esto involucró rediseñar la forma en que los mapas de ES (B2, B3, B4, C1) son detectados. Desafortunadamente eso parece haber descompaginado el botón de encendido; una vez que Richard lo tenga resuelto, deberiamos estar en condiciones de realizar actualizaciones de firmware de manera totalmente automática.

6. EC code: Richard Smith re-factored the way the EC does its startup procedure so that an automatic restart now happens after a reflash. This involved re-working the way the IO maps (B2,B3,B4,C1) were detected. Alas, the rework seems to have broken the power button; when Richard gets that issue sorted out, we should be able to to fully automatic firmware updates.
7. USB: Marcelo Tosatti, working with Cozybit and Marvell in California, made great progress in debugging our USB suspend/resume issues. Javier Cardona and Marcelo were able to acquire accurate traces of the activity on the USB bus. Those traces showed that the USB host controller is entering an invalid state during resume if the wireless device detaches after getting the host_sleep_active notification from the host. Their workaround is to have the wireless device idle for 3mS on the USB bus before detaching; they implemented that in wireless firmware version 5.110.16.p0. This is great progress towards fully working suspend/resume.

7. X Window System: Bernie Innocenti has been working mostly on visual bugs this week. The “iGoogle” bug was hard to find and easy to fix. The “green icons” bug was easy to find and hard to fix. Bernie has also pushed the Ethiopian and Urdu fonts in the builds.
8. Wireless: Marvell's team in India released wireless firmware that incorporates the new mesh frame format as well as mesh beacon frames (5.110.15.p1). Their release was followed by the release of 5.110.16.p0, which incorporates the support for host sleep and the aforementioned workaround for the USB suspend/resume. Cozybit has also released patches for ethereal/wireshark that decode the new frame format. With this release, we are moving closer to the emerging 802.11s standard and we are also averting problems with existing access points that support lazy-WDS. Note that this firmware version is not interoperable with any previous released versions. Nodes running the new firmware will disrupt and be disrupted by nodes running older versions of the firmware. Q&A testing will be proceeding this week with the goal of incorporating the new frame format in the upcoming stable build. From a network-manager perspective this release greatly simplifies sensing for the presence of mesh nodes. Dan Williams continued work on the Libertas wireless driver. He also spent time getting Avahi ready for the network-manager auto-mesh code.

; Seguridad y actualizaciones : Scott Ananian y Michael Stone trabajaron a la par sobre el desarrollo de la funcionalidad de "actualizaciones en vivo" (ver http://dev.laptop.org/ticket/2517). Esta funcionalidad, disponible a partir del ''Build'' 595, permite al usuario de una laptop ejecutar el comando <tt>"olpc-update NNN"</tt> para actualizarla al ''Build'' NNN. Scott trabajó con Michael Stone para lograr una actualización en la red interna inicialmente. Una vez realizada la actualización en vivo, descubrieron ciertas ineficiencias en nuestro dieño de la verificación del manifiesto. Michael analizó el rendimiento del software y, junto con la ayuda de Scott e Ivan Krstić, desarrollaron una mejora que permite reducir a la mitad el tiempo necesario para verificar un manifiesto. Scott mejoró la velocidad de la actualización interna en 10 veces al re-escribir la verificación de contenidos.

: Scott trabajó con Mitch Bradley en sacudir al proceso de arranque-seguro. Entre otras cosas, retocaron los formatos de ''lease'' del desarrollador y el de activación basados en sugerencias realizadas por Michael Stone y SJ Klein.

8. Security and updates: Scott Ananian and Michael Stone worked closely together to implement the “live updates” feature (See http://dev.laptop.org/ticket/2517). This feature, available since Build 595, allows the laptop user to run the command “olpc-update NNN” to update to Build NNN. Scott worked with Michael Stone to get an initial in-system network upgrade in place. After completing live updates, they discovered certain inefficiencies in our implementation of manifest verification. Michael profiled the software and, with Scott and Ivan Krstić's help, developed an enhancement that halves the time required to verify a manifest. Scott improved the speed of the in-place upgrade by 10× by rewriting contents verification.
9. Sugar: Ben Saller continues work on the data store for the Journal. He has been working on support so that one can store Journal entries on pluggable media (such as USB keys) and access entries over the network. He also fixed several bugs that Tomeu Vizoso and Marco Gritti needed.

Jean Piché and the core TamTam team spent the first half of the week at the OLPC office in Cambridge working closely with Eben Eliason on reworking the TamTam interface in light of Sugar “tabs” and some new functional and structural ideas that the team has been exploring. The result will be a recasting of MiniTamTam into TamTamJam, which will enable the explorations and improvisations we enjoy in TamTam to extend across multiple machines on the mesh; and a cleaner integration of the rich and varied functionality of TamTamEdit, making this powerful composition tool more accessible. They also did some preliminary exploration of Barry Vercoe’s fixed-point C-Sound implementation; evaluated TamTam on the B3 hardware; and discussed details of Journal integration with Tomeu.

next week. This toolkit is intended to allow children to easily create
arcade-like games on the XO.

Lincoln Quirk has been working on integrating PyGame with Sugar. He has taken Noah Kantrowitz's wrapper code and extended it, but there are problems integrating properly with GTK. For the last few days, he has been working on a Cairo-based implementation of PyGame, which is starting to work, but is so far quite a bit slower than the existing PyGame code. It may be fast enough to use for some games, it looks beautiful, and we hope it will get faster over time.

Roberto Fagá has been building an adventure game toolkit called ISIS intended to build text-based adventures with graphical illustrations. The longterm goal is to build a drag-and-drop storytelling game toolkit that kids can use. He just got his hands on an XO and is working on getting the graphics portion of the toolkit functional.

As a team, the gamers now have a git repository and have checked in all of their work, as well as other games from the OLPC game jam. There are several games that they hope to build on over the next few weeks, including a Mancala/Owari stone game that will support play either on a single machine or across the mesh.

Kuku Anakula, a flashcard-style game, has been polished for Trial 2; it can share configuration files and tile sets with the Memonumber game.

MaMaMedia has finished three activities: a slider puzzle, an e-poll generator, and a teacher center, the latter being a place for teachers to learn and contribute to how they can use activities to integrate XO programs (Paint, Camera, Write) into their teaching. In the teacher center, there are lesson ideas for exploring the XO and the activities, a glossary, some background on Constructionism, etc.

15. OLPC Philippines http://wiki.laptop.org/go/OLPC_Philippines has created a website, this will be a common place to put in notes soon. A project management site in zoho.com is under request for free account on open-source development. Rowen Remis Iral and Timothy Paul Martinez are receiving emails on how to get in touch with the government. List of some contact details are provided to OLPCPH.
11. Content: SJ Klein and Mel Chua, who organized the Game jam, are working on a generalized notion of “jam,” for a broader community audience. The FHSST group in South Africa is running a jam out of Berkeley to make high school curricula and polish their texts. The Polish Free Texts project has their own variant on the theme for teachers. In progress: defining a space for collating links to such initiatives; developing a framework that allows for broad intake of all kinds of material, and for a refinement step that converts scans or documents into final formats for printing, storing in specialized repositories, storing on wikis and other collaboration sites. Meanwhile, SJ has been working on style guidelines for content contributions.


OLPCPH was prepared to attend the Curriculum Jam with some educators joining the Jam in Manila and to meet Mel Chua in the Jam.
The Commonwealth of Learning (COL) is planning some content jams for educators and authors towards the end of the summer and early fall. They are expanding their collaboration on free textbooks starting with wikieducator, where public domain texts are being added to the “XXI texts” project, a project to find textbooks that have entered the public domain. They are working with educators to get primary texts online and developing an OLPC project on the site. A new mailing list for free texts has been set up, with COL, an Arabic texts project, the Polish Free Textbook project, Free Culture's college texts project, and OLPC. The Open Society Institute is looking into ways to fund a specific short-term effort to bootstrap these groups and bring their efforts together.

There was an entire track at the third annual iCommons summit dedicated to open education. OLPC and growing rural networks were highlighted as an example of the most revolutionary target audience. Over the course of a year or so, there are many projects aiming to develop free materials and interested n focusing on developing-world primary school; beginning with the Shuttleworth Foundation and FHSST and Schoolnet projects in southern Africa.

Google’s OurStories continues apace and is looking for active contacts in each country to help coordinate story gathering via activities.

David Cavallo
ha formado un equipo de aprendizaje que trabajará con los paises para que desarrollen sus propios equipos de aprendizaje. El objetivo es ayudar para que cada país desarrolle un mayor entendimiento y prácticas más enriquecedoras en el uso de las laptops para el aprendizaje. Realizaremos talleres en la OLPC todos los meses, trabajaremos en los países, e internacionalmente. Los primeros talleres en países serán en Etiopía, Ghana, Rwanda y Nigeria durante el mes de octubre.

1. David Cavallo has formed a learning team that will work with countries to develop their own learning teams. The goal is to help each country develop a deeper understanding and richer practice in using laptops for learning. We will hold workshops at OLPC each month, work in countries, and collaborate internationally. The first workshops in countries will be in Ethiopia, Ghana, Rwanda and Nigeria during October.

Cronograma
Aún no tenemos un congelamiento total de código ya que quedan demasiados bugs críticos sin resolver. Si tienen algún bug bloqueante o de alta-prioridad abierto para Trial-3, por favor ayúdenos analizando la carga, haciendo sugerencias de como resolverlo o como documentar el problema, y marcándolo como "untriaged" para que el equipo lo revise. Por favor verifiquen con Jim Gettys o Kim Quirk antes de introducir cambios en el código.

2. Schedule: We still have not gotten to a full code freeze as there are too many open critical bugs. If you have blocking or high-priority bugs open for Trial-3, please help us by analyzing the work load, making a suggestion for a work-around or how to document the issue, and setting the bug to “untriaged” so that the triage team will review it. Please check with Jim Gettys or Kim Quirk before checking in any code changes.

Prueba
Alex Latham actualizó las notas de configuración de pruebas en el wiki para considerar los escenarios de configuración de acceso a redes: dos laptops bajo un árbol; una laptop conectada a un punto de acceso; y una latpop conectada a una malla del servidor escolar. También hay notas adicionales sobre configuraciones y planes de pruebas para la localización (ver Test issues. Alex Khitrick y Yani Galanis, se han "unido" al equipo de pruebas durante la semana para ayudar con la ejecución de los casos de pruebas, debuggeo y tomar notas de los bugs.

3. Test: Alex Latham updated the test configuration notes in the wiki to address network-access configuration scenarios: two laptops under a tree; laptop connected to an access point; and laptop connected to a school server mesh. There are also some additional configuration notes and test plans for localization (See Test_issues). Alex Khitrick and Yani Galanis have both “joined” the test team this week to help with executing test cases, debugging, and writing up bugs.

Hardware
El equipo de hardware (que incluye gente de Quanta y AMD) pasaron la semana tratando de rastrear algunos de los problemas pendientes de suspender/retomar. Hemos llegado al punto en el cual muchas laptops han estado corriendo durante cientos de miles de ciclos sin crashes, aunque todavía pueden ocurrir crashes ocasionales (y algunas laptops son más suceptibles que otras). Ninguna otra laptop se le acerca; pero tampoco tienen nuestro ambicioso objetivo de suspender entre lectura de páginas (o hasta entre pulsaciones de teclas), potencialmente llegando a los miles de páginas por día.
El limitado margen de ruido en la línea de +3.3V que alimenta la mayoría de las comunicaciones inter-chips (y la WLAN) de la laptop ha sido la gran sorpresa. Una sorpresa aún mayor fue que dicho margen estaba críticamente relacionado con el voltaje de la batería! Cuando la batería estaba baja, nuestra alimentación de 3.3V estaba cayendo por debajo de 3.15V, debido a una alimentación insuficiente de un transistor usado para apagar el +3.3V durante la suspensión.
John Watlington y Quanta han propusto una solución que está siendo probada. Esperamos que mejorando esto podamos cerrar definitivamente el bug de "imposible retomar usando el botón de encendido o inalámbrico" (ver http://dev.laptop.org/ticket/1835) — que de hecho eran dos problemas diferentes uno de los cuales fue resuelto la semana pasada—y tenemos razones para pensar que era en parte responsable del bug de "fallas de inicialización del USB inalámbrico al suspender/retomar" (ver http://dev.laptop.org/ticket/1752 y http://dev.laptop.org/ticket/2621).
Nota: cualquiera trabajando sobre problemas de suspender / retomar debe mantener sus máquinas enchufadas hasta que esté resuelto apropiadamente.
Chris Ball realizó pruebas nocturnas en varios de los cambios de hardware propuestos. El bug de retomar la inalámbrica están ocurriendo con menos frecuencia, tanto así como para que otros bugs del kernel sobre retomar tomen mayor prioridad (ver http://dev.laptop.org/ticket/3477 y http://dev.laptop.org/ticket/3479).

4. Hardware: The hardware team (which includes people from Quanta and AMD) spent this week trying to track down some of the remaining problems with suspend/resume. We have reached a point where many laptops are running for hundreds of thousands of cycles without crashing, but occasional crashes still occur (and some laptops are more susceptible than others.) No other laptop comes close; but neither do they have our ambition to suspending between each page read (or maybe even suspending between keystrokes), with potentially thousands of page views/day.

The low noise margin of the +3.3V line that powers most inter-chip communication (and the WLAN) on the laptop was the big surprise. An even bigger surprise was that the margin was critically dependent on battery voltage! When the battery was low, our 3.3V supply was dropping to below 3.15V, due to insufficiently turning on the transistor used to switch +3.3V off during suspend.

John Watlington and Quanta have a proposed solution which is being tested. We hope that improving this will close out the “unable to resume via power button or wireless” bug completely (See http://dev.laptop.org/ticket/1835) — it was actually two distinct problems, one of which was fixed last week—and we have reason to hope that it might be at least partially responsible for the “USB wireless suspend/resume failure at setup phase” bugs (See http://dev.laptop.org/ticket/1752 and http://dev.laptop.org/ticket/2621).

Note: anyone working on a suspend/resume problem should keep their machine plugged into line power until it has been properly modified.

Chris Ball ran overnight tests on many of the proposed hardware changes. The wireless resume bugs are now occurring rarely enough to have taken a backseat to other kernel bugs related to resume (See http://dev.laptop.org/ticket/3477 and http://dev.laptop.org/ticket/3479).

Firmware
Mitch Bradley publicó Q2C27, la versión del firmware planeada para el Trial-3. Incluye la capacidad de inicio-seguro (pero también puede arranar en modo no-seguro). Ha sido probado sobre sistemas B1, B2-1, pre-B3, B3 y B4. No lo usen sobre placas pre-B1—ya que las inutilizará (brick) debido a los cambios realizados en el microcódgo del controlador embarcado (CE). Notese también que no funcionará en placas Test-A debido a que el soporte de dichas placas ha sido eliminado del microcódigo.

5. Firmware: Mitch Bradley released Q2C27, the firmware released planned for Trial-3. It includes secure boot capability (but can also boot in a non-secure fashion). It has been tested on B1, B2-1, pre-B3, B3, and B4 systems. Do not use it on pre-B1 boards—it will brick them because of changes to the embedded controller (EC) microcode. Also note that it does not work on A-Test boards as support for A-Test has been eliminated from the EC microcode.

Código CE
Richard Smith refactorizó la forma en que el CE realiza la inicialización de modo tal que se reinicie automáticamente después de un reflash. Esto involucró rediseñar la forma en que los mapas de ES (B2, B3, B4, C1) son detectados. Desafortunadamente eso parece haber descompaginado el botón de encendido; una vez que Richard lo tenga resuelto, deberiamos estar en condiciones de realizar actualizaciones de firmware de manera totalmente automática.

6. EC code: Richard Smith re-factored the way the EC does its startup procedure so that an automatic restart now happens after a reflash. This involved re-working the way the IO maps (B2,B3,B4,C1) were detected. Alas, the rework seems to have broken the power button; when Richard gets that issue sorted out, we should be able to to fully automatic firmware updates.

Sistema X-Window
Bernie Innocenti ha estado trabajando esta semana principalmente en los bugs visuales. El bug de "iGoogle" fue difícil de acorralar y corregir. El bug de los "iconos verdes" fue fácil de encontrar, difícil de corregir. Bernie también empujó los tipos de letra para Etiope y Urdu dentro de los builds.

7. X Window System: Bernie Innocenti has been working mostly on visual bugs this week. The “iGoogle” bug was hard to find and easy to fix. The “green icons” bug was easy to find and hard to fix. Bernie has also pushed the Ethiopian and Urdu fonts in the builds.

Seguridad y actualizaciones
Scott Ananian y Michael Stone trabajaron a la par sobre el desarrollo de la funcionalidad de "actualizaciones en vivo" (ver http://dev.laptop.org/ticket/2517). Esta funcionalidad, disponible a partir del Build 595, permite al usuario de una laptop ejecutar el comando "olpc-update NNN" para actualizarla al Build NNN. Scott trabajó con Michael Stone para lograr una actualización en la red interna inicialmente. Una vez realizada la actualización en vivo, descubrieron ciertas ineficiencias en nuestro dieño de la verificación del manifiesto. Michael analizó el rendimiento del software y, junto con la ayuda de Scott e Ivan Krstić, desarrollaron una mejora que permite reducir a la mitad el tiempo necesario para verificar un manifiesto. Scott mejoró la velocidad de la actualización interna en 10 veces al re-escribir la verificación de contenidos.
Scott trabajó con Mitch Bradley en sacudir al proceso de arranque-seguro. Entre otras cosas, retocaron los formatos de lease del desarrollador y el de activación basados en sugerencias realizadas por Michael Stone y SJ Klein. Scott también trabajó en la creación de un rediseño puro-Linux del proceso de auto-reinstalación, eliminando los dos reinicios con OFW y haciéndolo más compatible con el proceso de arranque-seguro.

8. Security and updates: Scott Ananian and Michael Stone worked closely together to implement the “live updates” feature (See http://dev.laptop.org/ticket/2517). This feature, available since Build 595, allows the laptop user to run the command “olpc-update NNN” to update to Build NNN. Scott worked with Michael Stone to get an initial in-system network upgrade in place. After completing live updates, they discovered certain inefficiencies in our implementation of manifest verification. Michael profiled the software and, with Scott and Ivan Krstić's help, developed an enhancement that halves the time required to verify a manifest. Scott improved the speed of the in-place upgrade by 10× by rewriting contents verification.

Scott worked with Mitch Bradley on shaking out the secure-boot process. Among other things, they tweaked the developer and activation lease formats based on suggestions from Michael Stone and SJ Klein. Scott also worked on creating a pure-Linux reimplementation of the auto-reinstallation process, eliminating the two reboots into OFW and making it more compatible with the secure-boot process.

Kernel
Andres Salomon paso la semana probando bugs abiertos; ayudó a la gente que estaba trabajando sobre el tema del temporizador del i2c, preparó parches para el upstream, revisó un montón de parches, e hizo limpieza del repositorio git olpc-2.6. La limpieza del git tuvo como resultado que una clonación tarda solo 15 minutos en vez de 90 minutos.

9. Kernel: Andres Salomon spent the week testing open bugs; he helped folks who were working on the i2c timeout issues, prepared patches for upstream, reviewed lots of patches, and did a cleanup of the olpc-2.6 git repository. The git cleanup means a clone takes only 15 minutes, down from 90 minutes.

Licenciamiento de contenidos
Jon Phillips ha estado liderando el trabajo en la integración de las licencias de Creative Commons al Diario. Se pueden ver las capturas de pantalla de sus maquetas en el sitio trac (ver http://dev.laptop.org/ticket/3529).

10. Licensing content: Jon Phillips has been leading an effort to integrate Creative Commons licenses into the Journal. Screen shots of his mock ups are in the trac system (See http://dev.laptop.org/ticket/3529).

Muestras de sonidos
El Dr. Richard Boulanger continúa recopilando colecciones de muestras de sonidos grabados específicamente para la OLPC por el equipo en Open Path Music. Las incorporaciones más recientes son sonidos bucales: sonidos de animales, gruñidos, aullidos, etc., más algunos cantos. Estas muestras están siendo incorporadas en actividades tales como TamTam.

11. Sound samples: Dr. Richard Boulanger continues to gather together collections of sound samples recorded specifically for OLPC by the team at Open Path Music. The most recent additions are are vocal sounds: animal noises, grunts, groans, growls, etc., plus some singing. These samples are being incorporated into activities such as TamTam.

Biblioteca
Mako Hill ayudó a re-escribir los fragmentos en JavaScript de la biblioteca para usar plantillas Python del sistema Jinja (vea http://jinja.pocoo.org/). Esto resulta en un diseño más robusto si JavaScript se encuentra deshabilitado. Las plantillas serán reusadas una vez que activemos el servidor web en los builds y cambiemos de un modelo de "actualizar la lista-de-paquetes al descargar" a una vista dinámica que verifica el sistema de archivos.
La página pre-establecida del navegador apuntará al repositorio local de contendio y tendrá enlaces para navegar la red. Actualmente hay enlace a:
  • google.com, que redireccionará automáticamente al idioma correspondiente al país;
  • el servidor escolar;
  • wiki.laptop.org/go/Home (inicialmente a la versión en inglés) en donde los enlaces a las páginas de actividades y paquetes de contenido estarán más visibles;
  • wiki.clusty.com, para buscar en Wikipedia (inicialmente en inglés);
Cualquier sugerencia adicional será bienvenida.

12. Library: Mako Hill helped rewrite the Javascript bits of the library to use Python templates using the Jinja templating system (See http://jinja.pocoo.org/). This is a more robust implementation if Javascript is turned off. The templates will be reused once we turn on a web server in the builds and change from a model of “update bundle-list on download” to a dynamic view that checks the filesystem.

The default browser page will point to the local content repository and have links to browse the web. Currently, there are links to:

  • google.com, which will auto-redirect to the proper language for the country;
  • the school server;
  • wiki.laptop.org/go/Home (initially English by default) from which the activity and content bundle download pages will be more prominently linked;
  • wiki.clusty.com, to search Wikipedia (initially English by default)

Additional suggestions are welcome.

Actividades biológicas
David Stang del ZipcodeZoo está trabajando junto a Lauren Klein para proveer una interfaz para niños sobre su base de datos referente a insectos para los "bug blitzes". Charles Smith de la fundación EOWilson está trabajando sobre ideas básicas e información general sobre como realizar "bug blitzes" en el contexto de una clase. Misha Hescu, una adolescente que ya ha publicado su primer libro "herpetología" en Massachusetts, está ayudando a organizar el trabajo con ZipcodeZoo. Misha también ayudó a contactar a un grupo tailandés que estaba realizando sus propias actividades de búsqueda de insectos con un zoo poco tradicional de insectos en el norte de Tailandia, que quizás pueda ayudarlos a expandir el trabajo ya realizado, y quizás poner en línea las primeras fotos de algunas especies de insectos. (ver http://www.malaeng.com/).

13. Biology activities: David Stang of ZipcodeZoo is working with Lauren Klein to provide a kid-friendly interface to his database of bug information for bug blitzes. Charles Smith at the EOWilson foundation is working on basic ideas and background information for classes running blitzes. Misha Herscu, a teenager who has already published his first book on herpetology in Massachusetts, is helping organize the work with zipcodezoo. Misha also helped connect the Thai group that was doing their own bug-finding activity with an unusual bug zoo in northern Thailand, who may be able to help them extend the work they have done. and perhaps take some of the first online photos of certain species (See http://www.malaeng.com/).

Radio
Schuyler Erle, quien trabaja en proyectos de radio y cartográficos para UNICEF, ha logrado hacer andar un programa de radio para la XO, convirtiéndola tanto en un receptor como un emisor.

14. Schuyler Erle, working on mapping and radio projects for UNICEF, has gotten a radio program to work on the XO, which can make the XO an audio receiver and broadcaster.
