OLPC, Quanta, Fuse, Gecko y Pentagram se reunieron en las oficinas de Pentagram para hacer la revisión final de la mecánica para la B4. La corrida de la B4 está programada para el 22 de junio. Al menos unas 2.000 unidades serán fabricadas en una o dos semanas; intentaremos fabricar más de ser posible.

1. NYC: OLPC, Quanta, Fuse, Gecko, and Pentagram met at the Pentagram office to do the final mechanical design review for B4. B4 build is scheduled for June 22. At least 2000 units will be built over a one-to-two week period; we are trying to find a way to build more units if possible.

Washington DC
Nicholas Negroponte y Walter Bender estuvieron el jueven en el Banco Mundial invitados por Ruth Kagia, Director de Educación. Tras una presentación a ~50 miembros y una sesión de preguntas y respuestas de una hora hicieron desaparecer muchas de la desinformaciones sobre la OLPC y generó un gran entusiasmo hacia la misión de la OLPC.

2. Washington DC: Nicholas Negroponte and Walter Bender spent Thursday at the World Bank. Our host was Ruth Kagia, Education Director. A presentation to ~50 staffers and a hour-long Q&A session both dispelled much misinformation about OLPC and generated enthusiasm for the OLPC mission.

Adaptadores de Corriente
Las investigaciones de Mary Lou Jepsen sobre la temperatura de quemado de la piel en niños, resultó en una nueva temperatura máxima de los adaptadores de corriente en el estándar de UL, bajándola de 85C a 75C. (Cuando fué la última vez que una compañía buscando certificación ayudó a hacer las especificaciones más estrictas?)

3. Power adaptors: Mary Lou Jepsen’s investigation of burn temperatures for children’s skin resulted in UL lowering their maximum temperature allowed for the OLPC AC adaptor from 85C to 75C. (When was the last time that a company seeking certification helped make the specifications tougher?)

Certificación
Diez laptops B3 fueron enviadas a UL para pruebas de certificación bajo normas UL60950. Uruguay a pedido nuestra certificación de resistencia al agua. Mary Lou está investigando las pruebas: probablemente seamos capaces de alcanzar IP42, o mejor. IP42 quiere decir que un alambre de pruebas de 1mm de diámetro no podrá penetrar la carcasa y que agua goteando a un ritmo de lluvia durante 2.5 minutos en cada una de las cuatro posiciones tampoco. Quizás logremos un mejor calificación, IP54 por ejemplo, que prueba si talco en suspensión logra penetrar la carcasa (algo poco probable dada la ausencia de ventiladores) y rociada en agua por una serie de chorros durante 10 minutos (quizás con la laptop 'cerrada').

4. Certification: 10 B3 laptops have been sent to UL for certification testing. They will be tested for UL60950. Uruguay has asked for our water-resistance certification. Mary Lou is investigating testing: we will likely be able to achieve IP42 and perhaps better. IP42 means that a test wire 1mm in diameter shall not penetrate the housing and water that is dripped at a rainfall rate for 2.5 minutes in each of 4 different positions shall also not penetrate the housing. We may be able achieve something better, such as IP54, which tests if a suspension of talcum powder ends up in the housing (unlikely due to our fanless operation) and water is sprayed for 10 minutes from a series of nozzles (might be possible in the closed tote-mode of the laptop).

Servidor
Fuse presentó un nuevo diseño conceptual para el servidor que permite poner ventiladores afuera de la carcasa para enfriarlo continuamente como una chimenea.

5. Server: Fuse presented a new concept design for the server that allows fans outside the housing of the server to cool it down continuously in a chimney type.

Baterías
El Profesor Sadoway de Ciencias de Materiales (Material Science) del MIT, visitó la OLPC esta semana para discutir sobre la química de la batería junto a Mary Lou, Richard Smith y John Watlington. Como resultado estamos investigando nuestras propias pruebas para la carga de LiFeP en temperaturas ambientales altas, así como el muestreo y reciclado.

6. Batteries: MIT Materials Science Professor Sadoway visited OLPC this week to discuss battery chemistry Mary Lou, Richard Smith, and John Watlington. As a result of his visit we are investigating our own tests of charging LiFeP at higher ambient temperature, as well as sampling, lifetime recycling.

Malla

Sugar
Ben Saller trabajó en la indexación de texto en el almacén de datos, lo que facilitaría la búsqueda en el Diario. Tomeu Vizoso y Marco Gritti han estado trabajando en el navegador y depurando la interacción con el almacén de datos y Sugar. También han estado refactorizando código preparándose para ponerlo en el nuevo build. John Palmieri trabajó sobre el video player totem como plugin y explorando lo que implicaría pasar a Fedora 7.

Funcionalidades futuras incluirán la prueba de las actividades y notificaciones vía RSS y email de los builds nuevos/fallidos. Muriel de Souza Godoi estará trabajando con Eben Eliason en el refinamiento de la interfaz de usuario y varias de nuestras actividades de Sugar estándar.

9. Sugar: Ben Saller worked on text indexing in the data store, which should make it easy to search in the Journal. Tomeu Vizoso and Marco Gritti have both been working on the browser and on the cleaning up the data store and Sugar interactions. They have also been refactoring code in preparation of putting it into new build images. John Palmieri spent time on the totem video player browser plugin.

Muriel de Souza Godoi will be working Eben Eliason on refining the UI in many of our standard Sugar activities.

Sistema X-Window

10. X Window System: The Geode LX has a significantly more capable graphics engine than the GX, which makes investing in optimizing its driver more important. Further, it is time to complete work on the input issues relating to screen rotation; this requires working on the “master” branch of X.org. Bernie Innocenti and Jordan Crouse worked on updating the Geode driver to the current X.org master branch, and fought and fixed a number of rendering bugs. There are some more bugs to be chased and squashed exposed by testing, though it again functions adequately for Sugar's current use. Jim Gettys refreshed his knowledge of xkb in preparation to adding keysyms now that the keyboard is finalized and our UI needs more clearly understood.

Gestión de Energía

11. Power management: Adam Jackson worked on display-controller (DCON) power management. The Geode has “compression buffers” that can greatly reduce bandwidth use for graphics by compressing pixels on their way to the screen. But even better is to be able to turn off the video output entirely, which the DCON makes possible, in which the Geode will entirely power down that part of the screen. A discovery by Mitch that enables us to restart the video unit on the Geode with almost no latency means that we can use DCON mode much more aggressively than we had expected, and may find it unnecessary to deal with compression buffers. We also want to dynamically control the frame rate; we can save 60mw (significant in ebook mode) by driving the panel at 25hz rather than 50hz. Adam has started on this work.

Kernel

12. Kernel: Andres Salomon synced the kernel up with 2.6.22-rc1. Unfortunately, this seemed rather broken; this week, Andres synced with 2.6.22-rc3, and it behaved much better. Andres also pulled in a new libertas driver. Marcelo discovered a bug in our suspend/resume code that was triggered by the updated kernel code; with that fixed, suspend/resume works in master again. (There is still some remaining console corruption that needs to be worked out.) Andres started digging into the vserver capabilities, which is key to the deployment of BitFrost.

Firmware

13. Firmware: Mitch worked on stabilizing the firmware for B4: he fixed minor bugs 1580, 1577, 498 and serious bug 1609. He reverted the automatic “freeze screen” (quiet boot) behavior due to the OS support not being ready for it. You can still use it by adding a “freeze” line in olpc.fth, and changed the startup sound so that you have to press a game key to hear it.

Note: Q2C14 is not recommended for general use; a new release will be issued as soon as Mitch get official EC bits from Quanta.

Controlador Embarcado

14. Embedded controller: Mitch added support for a new embedded controller (EC) command protocol to Open Firmware (OFW). Richard Smith worked on implementing the protocol. The protocol is mostly complete and partially tested. Its currently working well enough to switch the kernel over to using these commands. The next firmware release will have this new protocol enabled. Richard also tested an EC code drop from Quanta which worked on resolving some of our blocker bugs.

Hardware

15. Hardware: John Watlington spent most of the week rewriting and updating the XO Hardware Design Specification. This is the document that describes the basic hardware features of the XO in detail. The electrical design of the B4 is completed. There are very few changes from the B3 design, just fixes for remaining small problems. The motherboard was released by Quanta for circuit board fabrication.

Comunidad

16. From the community: Rob Savoye reports that since ffmpeg isn't (and probably will never be) included in the OLPC builds, he built a binary tarball of Gnash with full audio and video support. (The Gnash build for 406 has no video support enable for Flash codecs.) You can download this snapshot of the upcoming Gnash release from ttp://gnashdev.org/olpc/download.html. The tarball gets installed in /usr/local, and the plugin gets installed in /usr/lib/mozilla/plugins. The embedded video performance is adequate, streaming performance is around 3-5 fps max. (This was on a B1. B3 results will be reported soon.)
