*Network / Collaboration* Ricardo Carrano: * The multicast filter. To avoid waking up a suspended XO at every multicast frame received (they can be pretty frequent in a dense mesh) a multicast filter was implemented in the firmware release 22p8. Now the driver should announce the multicast addresses of interest. If it does not we have problems like #6818. A driver patch is now being discussed by Marvell and David Woodhouse. There has also been discussions (at the devel list) on the limit of 8 mac addresses in the filter.
* The 6589 blocker. We are still fighting in the #6589 front, the fix included in the firmware 22.p9 (that also needs kernel support) was the introduction of a "firmware ready" event (or a 200ms wait time for backward compatibility). This fixed the bug but caused a race condition as a side effect, so a new firmware release - 22p10 was released (today). Relase 22p10 is the current firmware version under test now, and the next candidate to go into joyride (22p8 and 22p9 will be skipped) and succeed 22p6. Giannis Galanis: I updated the Update.1 release notes at http://wiki.laptop.org/go/OLPC_Update.1_Software_Release_Notes for most network issues. I also included most bugs we discovered with Wad in Peabody 100 laptop test. Guillaume Desmottes: * Investigated PS bugs that have been filed due to latest test beds. * PS bugs triaging * Wrote some improvements in PS and Telepathy to help debugging. * Discuss 1-1 tubes protocol in Salut * Reviewed a D-Bus tube fixed I have spend lot of time this week digging into presence bugs that have been filled by Wad according his observations during latest test beds (#6880 and next). I wrote a not-reviewed-yet Gabble fix for one of them (#6883) and improved PS debugging output and telepathy-glib to inform us when CM are disconnected from the bus (#6905). That should, hopefully, give us more information on some strange and hard to reproduce bugs. Morgan Collett: * Started my new role for OLPC, working on activity collaboration * Started http://wiki.laptop.org/go/Collaboration_Central as a page to track collaborative activities, developer resources and news about collaborative activities * Tested Jani Monoses' packages for Sugar in Ubuntu 8.04 (hardy) which is due to release next week as this will be a very useful way for people to run Sugar to write activities * The theme for this week's sugar developer meeting on IRC was collaboration. We had a good discussion about API issues in particular. * Started reviewing the state of collaboration code in core activities: submitted patches for Write for #5062 and #6021. * Process/Release* Michael Stone: This week, I published two commentaries on planning and I spent many hours working to broaden and deepen communication channels throughout the project. I also helped prepare a collection of activation leases for Mexico and I began trying to comprehend what packages could be updated in a near-term bug-fix release if the need arose to make one. Kim Quirk: Wrote up the first level of detail feedback from the sales team as to the priority of bugs fixes and features needed. I presented a summary of what works and diagrams of basic network configurations that have been tested and documented. There was much discussion about activation leases and mesh/collaboration. The sales team is also interested in easier XO upgrades, more video/text documentation of how things work, and better battery life. This information is part of the goals and priority planning that has been discussed heavily on various mailing lists. Dennis Gilmore: * started branching things for dist-olpc3 based on F-9 for testing * spoke with Fedora Brazilian Ambassadors on how they can help OLPC *General Software issues* Sayamindu Dasgupta: I have been figuring out possible ways to make the language packs more effective. Currently, the existing language packs are only a hackish solution to quickly check translations (and contains the translations only for the bleeding edge development branch). For actual deployment scenarios, we need more fine grained control over the contents of the language packs. Some of the "parameters" which should go into the building of the language packs (so that deployers can create a custom language pack for their deployments) include: a) Branch being followed (ship-2, update-1) b) Activities being included in the deployments I'm working on a web based tool which can do this - hopefully I'll be able to come up with something by next week. I also made a short presentation in the first meeting (over telephone) of OLPC India (which happened this Friday), outlining our translation workflow, so that people interested in contributing to the translation efforts can join us. Andres Salomon: - worked on getting more stuff upstream (I gave a summary of that at the software meeting, I'll give another update for weekend once the patches are actually in Linus's tree). - cleaned up kernel build trees on filer (which made me discover some long lost patches). This is still in progress, it's slow going. Eben Eliason: * Polished visual designs for the GUI control panel, and exported icons for its modules * Took an extremely thorough first pass at refining the visual and interaction design of the Journal * Undertook a rewrite of the activity launch feedback code, providing a new model that should improve stability in the field and emphasize the zoom metaphor that the UI is built on. *Support:* Adam Holt, Emily Smith, and Sandy Culver continue to work hour by hour through all the issues associated with non-deliverable laptops, returns, refund requests, tech support questions, and just listening to people who really need to vent. Michael Stone and Richard Smith helped to support Mexico's deployment by debugging and working around problems with the OLPC manufacturing data server. This pointed out the need for better process and backups for the activation and lease management issues. Kim Quirk met with Bruce Lai and Tom Kambouras from NYC schools to go through their list of technical issues. They are hoping to start the rollout of 1500 laptops in the next few weeks. One of the requirements for all US schools is to be able to limit the wireless access of a laptop to only those belonging to the school. John Watlington will be visiting Peru again next week to help keep that deployment moving forward. *SysAdmin* Henry Hardy: * We are moving ahead with purchase of three new servers. These are to replace pedal, crank and xs-dev. * Still backing up the filer on grinch so that we can assure the data that is there before adding disks to the Coraid 1521 disk array. * On Thursday 17th of April 2008 1cc had a scheduled downtime of unexpectedly long duration for the upgrade of the wireless link from 1cc to MIT from 100MB to 1 GB. *Conferences / Other*: * Richard Smith did a presentation on "One Laptop Per Child and Alternative Power Sources" in conjunction with the Massachusetts Power Shift (MAPS) event at Boston University on 2008-04-12. He was assisted by SJ Klein and Henry Edward Hardy. * SJ Klein and Henry Edward Hardy presented an XO to the MIT Museum for their permanent collection on 2008-04-16. John Durant, the Director of the MIT Museum and Deborah Douglas, the Curator of Science and Technology wish to express their sincere thanks for our donation of an XO for their permanent collection today. They are keen to have a few more current models for hands-on demonstrations, and would very much like to do an historical exhibit showing the key stages of conception, design, production and deployment. Picture of Scott giving his talk at FISL (provided by Dennis Gilmore): http://www.ausil.us/gallery/main.php?g2_itemId=3227 Wad and Kim visited 2 possible sites for the next home of the 100 laptop test bed. One is the old Rounder Records building near Davis Square and the other is a garage behind the cinema at Fresh Pond Mall near the Alewife T. * SJ has offered to pick up the management of the Developer's Program, which is ready to start sending out laptops. It has been a number of months since this program was running. Please send people to http://projectdb.olpc.at/
