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.

; CE (''EC'') :
; Olin College : Fue sede para el [[Game Jam/lang-es]] el fin de semana pasado, reuniendo diez equipos de desarrolladores de juegos junto a algunos artistas, músicos y programadores; para realizar juegos para la XO. Los organizadores [[User:Mchua|Mel Chua]] y [[User:Sj|SJ Klein]] ahora se encuentran trabajando en notas generales sobre como organizar ''game jams'' y otros eventos comunitarios orientados a desarrollar material para la XO. La mayoría de los equipos eligió trabajar sobre [[Python/lang-es|Python]], aunque un par lo hicieron en Flash. (Un ferviente desarrollador de Flash que no quería saber nada de Python al inicio, para el domingo, no podia dejar de hablar de las virtudes de Python). Los equipos colaboraron entre ellos, amén de competir entre ellos para desarrollar el mejor juego; compartieron música y experiencias artísticas, fragmentos y consejos de código. (Unánimamente, los desarrolladores Flash querían desarrollar de modo tal que funcionase sobre nuestra plataforma en Gnash, en vez del estándar Flash 9; pasaron parte del viernes y el sábado trabajando con el equipo de Gnash con el fin de mejorar sus capacidades para el desarrollo de juegos sobre él).
: Los dos juegos mejor evaluados usaban PyGame; ellos fueron una versión de ''3D Pong'' y una version de ''Crossfire'' llamada ''Spray Play'' (Vean [[Media:3dpong.activity.zip]] y http://sprayplay.googlecode.com/svn/

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.
2. Olin College hosted the first OLPC Game Jam (See

[[Game Jam]]) last weekend, bringing together
ten teams of game developers and some freelance artists, musicians,
and programmers, to make games for the XO. Organizers Mel Chua and SJ
Klein are working on general notes re: organizing game jams and other
local community events to develop materials for the XO. Most of the
teams chose to work in Python, though a few developed in Flash. (A
Flash developer who had rather vehemently against Python at the start
of the weekend, wouldn't stop talking about how nice Python was by
Sunday.) Teams collaborated with one another, in addition to competing
to make the best game; they shared music and artistic expertise, and
code snippets and coding advice. (The Flash developers uniformly
wanted to write things that would work in Gnash on our platform, not
standard Flash 9; they spent part of Friday and Saturday working with
the Gnash team to help improve its utility for game development.)

The two best reviewed games both used PyGame; they were a version of
3D Pong and a version of the old Crossfire game called Spray Play (See
[[Image:3dpong.activity.zip]] and
http://sprayplay.googlecode.com/svn/).

; Entrando en calor : [[Image:Taking-the-heat.JPG|thumb|right|Laptop asándose a 52C durante el día, y a 22C durante la noche.]] Hemos decidido averiguar cuanto calor puede aguantar la XO. Mary Lou Jepsen dio instrucciones al UL para probar nuestra laptop en un ambiente de uso a 50C (122F). Las laptops típicas son solo probadas a 35C (95F) o 40C (104F), lo que es inaceptable para los chicos usandolas en climas calientes (ej: directamente bajo el sol y sin aire acondicionado, obviamente). Mary Lou y Tracy Pride también están llevando a cabo una simple prueba de cocido en las oficinas de la OLPC. La laptop está operando durante el día a 52C (125F), y durante las noches a 22C (72F). UL y Quanta realizan pruebas más a fondo, pero en la imagen se puede ver una laptop corriendo la demo de [[Etoys/lang-es|Etoys]] en el horno, día y noche. Prueben eso en una laptop convencional!

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.

3. Taking the heat: We have decided to see how much heat XO can take.
Mary Lou Jepsen has instructed UL to test our laptop for a 50C (122F)
operating temperature. Typical laptops are only tested to 35C (95F) or
40C (104F), which is unacceptable for the children who will be using
our laptops in hot temperatures (e.g., in direct sunlight and of
course without air conditioning). Mary Lou and Tracy Price are also
running a simple bake test at the OLPC office. The
laptop is running days at 52C (125F), and nights at 22C (72F). UL and
Quanta are doing more extensive testing, but shown is a laptop,
running the eToys demo that sits in the oven night and day. Try that
with a conventional laptop!

; Firmware :
; Verde : Mary Lou y Robert Fadel han comenzado con el proceso de aplicación de EPEAT Gold&mdash;la mayor calificación para laptops; ninguna otra laptop lo ha obtenido aún. También, a fines de la semana, Ethan Beard y Megan Smith de Google y Mike Evans de Red Hat, invitaron a la OLPC a unírseles junto a Google, Intel, Quanta, Red Hat, AMD, HP y otros en el lanzamiento de ''Climate Savers'', una organización dedicada a reducir el consumo energético de las computadoras por medio de sistemas que permitan una mejor gestión de energía, y mejores adaptadores de corriente. ''Climate Savers'' eligió menor consumo como el punto más sobresaliente sobre el cual concentrar los esfuerzos con el fin de lograr el mayor impacto positivo sobre el medio ambiente. La OLPC concuerda con esa idea. Como inicio, aquellos que se unan a ''Climate Savers'' deberán conformarse a los lineamientos del ''Energy Star''&mdash;la OLPC es 14 veces mejor que dicho estándar.

Beard and Megan Smith, and Red Hat's Mike Evans invited OLPC to join
with Google, Intel, Quanta, Red Hat, AMD, HP and others in the IT
industry to launch Climate Savers, an organization dedicated to
lowering the power consumption of computers through better power
management systems, and more efficient AC adaptors. Climate Savers
picked lower power as the single thing on which to concentrate in
order to have the biggest positive impact on the environment. OLPC

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 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.

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.

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.

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.

; Kernel : Andres Salomon unificó el parche del árbol de dispositivos (''device-tree''), dando así acceso al hardware y datos de fabricación. La versión del piloto inalámbrico que soporta el suspender/retomar también fue unificado. El protocolo del EC (''embeded controller'') fue depurado, y depurado aún, con lo cual casi está listo. Disponemos ahora de una combinacion de kernel/firmware que permite suspender/retomar en unos dos segundo. La demora se debe principalmente a Libertas y el USB; Marcelo Tosatti y el equipo de Cozybit están trabajando activamente sobre estos pilotos.
: Chris Ball ha hecho un montón de depuraciones para el ''build'' estable. Descubrió que nuestro mapa de colores de la cámara se enrarece despues de retomar y que el LED de "cámara activa" se ilumina aún cuando no está en uso. Chris escribió un parche para el kernel para energizar la cámara solo cuando lo desea el usuario; Jon Corbet lo está revisando.

15. Kernel: Andres Salomon merged the device-tree patch, giving access
to hardware and manufacturing information. The wireless-driver version
supporting suspend/resume was also merged. The EC protocol was
debugged, and debugged some more, and is now mostly fixed. We have a
kernel/firmware combination that suspends/resumes in about two
seconds. The delay is mostly from libertas and USB; Marcelo Tosatti
and the Cozybit team are actively working on these drivers.


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.
Chris Ball did a lot of stable-build debugging. He found that our
camera's colormap becomes strange after resume and that the
"camera-active" LED comes on at resume even when the camera isn't
being used. Chris wrote a kernel patch to only power up the camera
when a user wants it; Jon Corbet is reviewing the patch.

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.

; IPv6 : Scott Ananian comenzó la semana intentando meter la totalidad de «Essential IPv6 Networking» en su cabeza. Armó un par de túneles IPv6 y migró su casa a IPv6 para:
: (A) asegurarse de entender como funcionaba la cosa; y
: (B) ser el campo de pruebas para el ambiente del servidor escolar, que probablemente se encuentre tras NATs similares.
: Se convirtió en nuestro representante (''liason'') con SIXXS, quienes nos proveerán de conectividad IPv6 vía túneles por el momento, hasta que armemos nuestra infraestructura (y escribamos algo de código) para ser terminal de túneles NAT de IPv6 aquí en Cambridge. Scott también nos confirmó que las direcciones privadas de IPv4 son correctamente asignadas a las laptops si un servidor DHCP no puede ser contactado.
: La segunda tarea de Scott relativa a la administración de redes fue entender la información DNS enviada como mensajes de notificación de routers como parte de la autoconfiguración IPv6, de modo tal que las máquinas "simplemente funcionen" sin requerir de viajes de ida-y-vuelta a un servidor DHCP u otras configuraciones. Scott notó que <tt>radvd</tt> en nuestra (OLPC) red local (tubos) estaba dando información "falsa", y escribió un parche para <tt>radvdump</tt> y lo envió a los responsables para su procesamiento. Resultó ser que <tt>radvd</tt> estaba usando un <tt>config</tt> viejo y que solo necesitaba que se le envíe un SIGHUP, algo bastante simple. Scott envió mails a varias personas (incluyendo la lista de correos del kernel correspondiente) detallando un plan para soportar DNS-en-RA en el kernel de Linux y el Network Manager. Scott no ha recibido ninguna objeción por el momento, con lo cual suponemos que el plan sirve y escribirá un primer borrador del código para la semana que viene.

16. IPV6: Scott Ananian began the week by trying to cram the entirety
of "Essential IPv6 Networking" into his head. He set up some IPv6
tunnels and IPv6-enabled his home site to: (A) make sure he knew how
things worked; and (B) serve as a testbed for the school server
environment, which will likely be behind similar NATs. He took over as
the liaison to SIXXS, which is going to be providing our IPv6
connectivity via tunnels for the short term, at least until we set up
infrastructure (and possibly write some code) to terminate
NAT-tunneling IPv6 tunnels ourselves here in Cambridge. Scott also
confirmed that private IPv4 addresses are properly assigned to the
laptops if a DHCP server cannot be found.


Kuku Anakula, a flashcard-style game, has been polished for Trial 2; it can share configuration files and tile sets with the Memonumber game.
Scott's second network-manager-related task was to get it to
understand DNS information sent via Router Advertisement messages as
part of IPv6
autoconfiguration, so that the machines "just work" without requiring
round-trips to a DHCP server or other setup. Scott noticed that radvd
on our local (OLPC) network (tubes) was giving out "bogus"
information, and wrote a patch for radvdump and sent the patch
upstream in the process. As it turns out, radvd was still using a
stale config and just needed to be sent SIGHUP, which was simple
enough. Scott sent mail to a number of people (including the
appropriate kernel mailing list) outlining a plan to add support for
DNS-in-RA to the Linux kernel and to Network Manager. Scott hasn't
heard any objections yet, so will assume
the plan is good and code up a first-draft implementation next week.

Shanghai | CE (EC) | Servidor escolar | Firmware | Sistema | X11 | USB | Inalámbrica | Sugar | Actividades Sugar en la Comunidad | Contenido

Shanghai

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.

CE (EC)

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.

Servidor escolar

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.

Firmware

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.

Sistema

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.

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.

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.

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.

X11

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.

Actividad de Escribir

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.

Inalámbrica

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.

Sugar

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.

Guillaume Desmottes spent the week working on peer-to-peer tubes support so that more than two people can join an activity (instead of activities being strictly peer to peer). Large parts of this code are working today. There will be more progress next week.

Marco spent much of the week working on the Fedora 7 port. He also made a number of fixes in the Journal, the theme, and Sugar in general. He is largely concentrating on Trial-2 bug fixes. He wrote a simple activity to demonstrate how to integrate with the Journal (See http://dev.laptop.org/~marco/edit-activity).

Marco and Chris Blizzard worked with the Fedora Translation team to set up an easy-to-use interface for translators to be able to help translate Fedora. A Google Summer of Code student has been working on a web interface that makes it easy for the several hundred Fedora translators to interact with upstream projects like OLPC (As and example, see http://translate.fedoraproject.org/module/olpc-journal-activity). We do not have all of the work flow completed, but this is an important first step to closing the loop with translators.

Tomeu spent the week doing a lot of bug fixing in the web activity, the Journal and the Sugar shell. He also did a lot of testing of the data store and worked with Ben to fix bugs that he found. In addition he added a lot of new stuff for Trial 2, including:

  • implement of modal dialogs for the web browser;
  • in the Journal:
    • you can now change an entry title;
    • install and execute activities you have downloaded (but are not on the main toolbar);
    • take a screenshot of the activity's canvas and use it as a preview for an entry;
    • add a save-in-journal button to the default activity toolbar to
    • explicitly save something to the journal;
    • drag entries from the journal into the clipboard; and
    • use the object-type registry;
  • in the sugar shell:
    • add an option to save objects in the clipboard to the Journal;
    • make the clipboard also use the object-type registry.

Actividades Sugar en la Comunidad

10. Sugar Activities in the community: Marc Maurer has been working on collision detection for multiple-document editing. He and the rest of the Abiword team have an algorithm they are happy with. The really adventurous can look at the document (See http://uwog.net/~uwog/abiword/abicollab.pdf).

Ian Piumarta and Michael Rueger implemented the IPv6 support for Squeak and ready for the testing. This will enable various collaborative tools in Etoys work over the IPv6 mesh network. Scott Wallace published the FunctionTile feature to the public image; this enables the Etoys user to write scripts with mathematical functions. Bert Freudenberg's recent work encompasses: patching Sugar; X Windows System display support code for the Squeak virtual machine; and an Etoys hook to enables smoother integration of Etoys to the Sugar environment. Ted Kaehler and Alan Kay are working on the kids version of text editor written in Etoys, as well as the simulation of colliding billiard balls. Takashi Yamamiya is now looking at the final integration of a drag-and-drop mechanism. Yoshiki Ohshima helped the code generation part of FunctionTile, as well as the documentation of projects.

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.

Kent Quirk reports from the XO game-development front that Patrick DeJarnette has created the beginnings of a generic side-scroller game toolkit and has a demonstration game that is beginning to feel a lot “a-like a-Mario.” It hasn't yet been turned into an activity or tested on the XO, but the approach is sound and we should see it running 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.

In the teacher center, there are lesson ideas for exploring the XO and the activities, a glossary, some background on Constructionism, etc.
