__TOC__
1. 80 B3 machines arrived at the OLPC offices in Cambridge on Friday. These machines, which are close to final, feature the Geode LX processor, improved keyboard and touch pad, many electrical and mechanical enhancements, and a brightly colored XO logo on the back. First impression: Wow!!
</div>

2. Dorchester: Walter Bender paid a brief visit to the Lilla G. Fredrick Pilot Middle School, one of three one-to-one computing programs funded by the State of Massachusetts. Although they are not (yet) using XOs, Principal Debra Socia has observed all things we have come to expect: more teacher and student engagement, more parent and community involvement, a higher level of discourse around learning, more writing, etc.


For coverage of recent OLPC updates, see our [[twitter]] feed and [http://blog.laptop.org OLPC blog].
3. UL: Quanta and OLPC met with UL this week to determine the exact strategy for certification of the laptops. Nearly all testing will be done by UL Taiwan, close to the Quanta offices to allow close communication. The B3 units will undergo test starting end of next week. The main areas of test are thermal, electro-magnetic interference, and radio-frequency noise (from WiFi). We will test at 40C, 45C and 50C to determine our maximum sustained ambient operating temperature.


This page historically hosted announcements and news about OLPC, along with the Sugar Labs [http://wiki.sugarlabs.org/go/Sugar_Labs/Current_Events '''current events'''] page.
4. Green: Mary Lou Jepsen met with John Bullock, the author of the Basel Convention take-back protocol for mobile telephones. The Basel Convention was started in 1987 as a way to globally address toxic dumping through recycling and take-back programs. It has been ratified by almost all countries, a notable exception in the USA. John, a recycling expert, said “OLPC has set a new environmental standard with XO” and wants to find a way to both help us continue, and to get the story out to other CE manufacturers. He offered many suggestions for improving our environmental position.


== Upcoming pieces ==
5. Sugar: Over the last couple of weeks we have seen great advances in the Sugar user-interface and the underlying systems that support it. A particular ficus has been on the mechanisms for collaboration:
; Claudia
: Learning Chat piece: 278 words, ready now. [[File:Learning Chat.docx]]
: Making Learning Visible: Claudia's (& Walter) original is 25 pages. Submitted to a journal. w/o OLPC Background it is down to 12-15 pages w/ screenshots.
: This can become a 4-part series.
; Antonio: Homo docens: 500+ words, Antonio approved my edits. [[File:Homo docens JLedits.docx]]
: Further work: we can definitely ask him to contribute on a quarterly basis but I've found that I have to be very specific as to what I am asking to do and he has to be comfortable that it is consistent with his academic work.
: Ask for a new piece on the epidemiology of learning
; Rodrigo:
: [[Ometepe]] - A beautiful piece with wonderful images. RAH posted a personal and lengthy version (1500+ words) that he shared with his private distribution list. I made an edited version (1200 words) that could be shared publicly. Must check with RAH on this. [[File:Ometepe articulo por Rodrigo Arboleda.pdf]] [[File:Ometepe by Rodrigo Arboleda (3).pdf]]

== News archives ==
* Marc Maurer has the Abiword-based Write activity hooked up to the Presence Service and Tubes API so it can find other people on the network. He is the first person who has tried to do it from C/C++; we are interested in seeing that experience documented.


'''[http://lists.laptop.org/pipermail/community-news/ Weekly OLPC News postings]''' to the community-news mailing list give updates on recent work. Weekly summaries were also posted on-wiki during [[OLPC:News/2008|2008]]. Weekly postings to the list were put on hold at the start of 2009, and started again in 2010.
* The Collabora team has been making a lot of fixes to the Presence Service. They have also been working on patches to dbus to fix some issues and are pushing for a new dbus release. John Palmieri is integrating those patches and working on a new release.


Archives: [[OLPC:News/Archive 1|2005-2006]]
* The Collabora team has also been working on a stream API that will make it very easy for activities that want to talk directly with each other to do so from the Presence Service. And they have started work on integrating the peer-to-peer (called salut) XMPP code into the Presence Service.

* Marco Gritti and Tomeu Vizoso have been very busy working on new web activity features. They have a new feature that makes if very easy to embed the browser directory into a python program and makes it possible to access the DOM directly from python instead of having to do it from C++. As a result, they were able to implement session restoration and saving of data to the Journal.

== [[OLPC:Videos|OLPC videos]] ==
* Marco also hooked up the xdg mime system into Sugar. This is one of the pieces required to let activities say which mime types they handle and how to associate them in the Journal.
For a history of videos about OLPC and the XO, see [http://olpc.tv olpc.tv] and [[OLPC:Videos]].


== Sugar news ==
* Tomeu has also been working with Ben Sadder to implement new features in the data store that are needed by the Journal.
Walter continues to post summaries of Sugar development '''[http://walterbender.org/?cat=3 on his blog]'''.


== Press ==
* Chris Ball began work setting up a tinderbox for Sugar, so that our activity and Sugar developers can see whether a Sugar build will succeed before trying it themselves. This should save them a lot of time as the Sugar build pulls in many external modules and often fails.
For an archive of OLPC media coverage, see the [[OLPC:Press/2005-2008|2005-2008 press archives]].


== Past announcements ==
* Chris also came up with a kernel patch to expose our ebook-mode “flip” kernel events to the input layer, which is where HAL listens for them. Once that's tested, we can have rotate on ebook-flip happening through Sugar, on a per-activity basis.
Developed through 2011 by the Racepoint Group, OLPC's ''pro bono'' PR firm.
6. Etoys: Bert Freudenberg continues on dbus support in Etoys; bypassing the launcher program written in Python, the start up time of Etoys will be much shorter. Takashi Yamamiya's work on clipboard is also continuing: he is experimenting with the X protocol to copy objects from Etoys to Sugar, where they can be accessed by other activities, including the Journal. Yoshiki Ohshima is working on the integration with Pango. which will allow more and better language support in Etoys. Scott Wallace has been experimenting expression tiles and Ted Kaehler continues work on an Etoy example of physics simulation.

7. School server: Dave Woodhouse worked with John Watlington on the configuration of IPv6 and the school server. Holger Levsen has built a local mirror that now carries the Fedore Core 6 and 7 source for i386, PowerPC. Building the livecd now only takes 33 minutes compared to 45 minutes against a remote mirror. The mirror is located at http://fedora.laptop.org. Holger reports that last week’s issues in Anaconda were fixed by upstream, but he found a new bug, which prevents using a kickstart-file and thus automated installations at the moment. Luckily this error happens in textmode and graphical mode, so I expect it to be fixed soon. (The manual workaround for the moment is to not use a kickstart file and answer the questions about partitioning and networking manually.) Builds are available at http://xs-dev.laptop.org/holger/ and documentation is found at [[User:Holger]].

8. Power management: Chris Ball talked with David Zeuthen (HAL maintainer) and Richard Hughes (gnome-power-manager maintainer) about the best way to design our power manager. Chris upgraded to the latest version of HAL and tested that it can expose our lid open/close events over dbus. Adding functionality to go to sleep with the backlight off when the lid is closed is only a few lines of code away now.


9. Suspend/resume: Marcelo Tosatti has been working on USB suspend/resume. He also has been working with Cozybit on trying to track down some suspend/resume issues with the wireless firmware. And he has been verifying another fix related to suspend with a starvation problem for the gc thread for the jffs2 filesystem; it sounds like this is fixed. Bernardo Innocenti and Dave Woodhouse also fixed a bug in the kernel serial driver on LX resume.


[[Category:OLPC]]
10. Systems infrastructure: Mitch Bradley investigated redoing the startup scripts in our system, which will end up being about 1/6th the previous size, understandable by mere mortals, and speed boot time. Chris Ball took a tcpdump of the web browser rendering over Ethernet for analysis with netplot. Rob Savoye has been working with Bernardo Innocenti on integrating Geode specific GLibc functions, which will improve performance in a number of areas. Bernardo is also worked on setting up to do the X Window System build environment for power management and for better handling of our input devices.

11. Kernel: Jon Corbet has a patch to turn off the camera LED when it is not in use. Andres Salomon worked on a DCON bug that appeared in some B3 hardware; after a resume, some of the GPIOs were in an inconsistent state, resulting in problems with DCON interrupt handling. The real cause is still unknown, but open firmware (OFW) has been changed to ensure that the necessary GPIO bits become unset after resume. Richard Smith is investigating further. Andres also worked on branching a new stable kernel, syncing the libertas tree up with master, and also syncing master up with Linux 2.6.22-rc1.

12. Firmware: Lilian Walter been making sure that power on/off audio, SD and the camera work on B3. Lilian is also working on the IPv6 and ping6. She has some very simple code for the IP layer (no extra headers for now). Next is to work on the address resolution bit (maybe hard code it just to test the Ipv6 layer so far with ping6).

Mitch Bradley released released new firmware Q2C14 with several bug fixes, a first pass at “quiet” boot screen support, wireless LAN auto-boot support for manufacturing, microphone LED blink reduction code (reduces the cost of the hardware workaround. Mitch also showed Quanta how to make an initrd image for manufacturing diagnostics and rrticulated a scheme for the mechanics of quiet boot across the firmware, kernel, userspace, and X transitions.

13. Hardware testing: Richard Smith worked on the B3 hardware checkout. Helped John Watlington test all parts of the system, including the firmware protect circuitry. Further testing (separate from the tens of functional tests that each XO is subjected to as part of the manufacturing process) includes such favorites as:
* Thermal shock: spending twenty minutes at –20C, then jumping to 60C in less than two minutes; staying at 60C for 20 minutes, then dropping back to –20C in less than two minutes (the whole process is repeated 50 times);
* Thermal profile: taking the temperature of most chips on the motherboard, while running a suite of applications at 50C;
* Altitude testing: operation tested for 8 hrs at 5.5 Km;
* Free-drop steel-ball test (onto LCD);
* Free-throw test: simulating a child free throwing an XO, its battery, and power brick onto the floor.
