1. Cambridge: A third Learning Workshop was held at OLPC this past week. There was excellent attendance and participation; a real network of laptop learning activists is forming. Workshop attendees are not merely listening but are contributing to the conceptual basis of practice in schools and communities. There was a blend between the conceptual and practical concepts, and the localities beginning will help innovate the learning environments and communities of the 21st century. The presentation by Dr. Felton Earls and Maya Carlson of the Harvard School of Public Health on participatory surveys and indicators for community development as well as their work in Tanzania and Chicago was inspirational. The Learning team of Edith Ackermann, Ed Baafi, Fatimata Seye Sylla, Juliano Bittencourt, Elana Langer, Julain Daily, Cynthia Solomon, Alice Cavallo, and David Cavallo contributed mightily. Special thanks for support especially to Felice Gardner, as well as Tracy Price and Jennifer Amaya. As always, a highlight is the Activity Open House where developers demonstrate their activities on the XO. |

2. G1G1: During the reconciliation process of the “get” laptops shipped during Give One Get One, a number of unfulfilled order records were uncovered. The OLPC team has been working hard with our partners to resolve all open issues. We expect another ~5000 XO laptops will be shipped on Monday. The remaining orders pose an extra challenge as they either have incomplete or no shipping and contact information. If you have not yet received your XO laptop, you should be getting an individualized email that addresses your specific situation. If you are scheduled to receive your laptop next week, you will also be getting a follow-up email with tracking information. We'll be adding additional phone lines and shifting agents to reduce wait times. A further reconciliation of the data will be conducted this week, although hopeful, we can anticipate additional incomplete orders. Our apologies for these delays. |

3. Ulaan Baatar: Enkhmunkh Zurgaanjin, Carla Gomez Monroy, Jan Jungclaus, and RedHat’s David Woodhouse are working hard to set up a structure that can provide sustainability to the project in Mongolia such that it can spread it throughout the country. On Wednesday, the Minister of Education visited the school for the “laptop hand out” event. On Friday, an optical-fiber cable was set up, in spite of the extreme low temperatures; on Saturday, the schools were connected to the Internet. David has been working with a group of local technical people on the servers and Internet set up infrastructure as well as on configuration. John Watlington has been providing support remotely from OLPC. |
|||
We have been meeting almost every evening with the strategic team of the Ministry of Education to provide feedback and sort out challenges. We met yesterday with the Ministry of Education team, teachers, principals, ICTA, content team and pilot research team to provide detailed feedback of how the project is going so far and to bring up things to be considered for the short and long terms. |
|||
Teachers are putting their hearts into the program. They had their first sessions with the children. Parents, too, have shown support. And the children, of course, love it. The Constructionist model of learning has found wide-spread support within the MoE. |
|||
There are more photos (See [[Ulaanbaatar]]) in our wiki. |
|||
4. School Server: John Watington reports that we have a new build which supports schools with multiple servers in a school and including a Jabber server! Build 150 was released, along with lengthy configuration notes (See [[XS Installing Software#OLPC XS 150]]). |
|||
The configuration interface is still stone knife and bear skin, but functionality appears to be there. We hope to have a build improving the configuration process and adding web caching by the end of next week. |
|||
David Woodhouse is in Ulaan Baatar, Mongolia helping Carla Gomez Monroy deploy school servers along with the laptops. The servers we shipped from Cambridge have arrived and are being installed. David has been handling the difficult task of positioning two servers (with six antennae) to cover a three-floor school. He is also facing the need to upgrade the laptops right away to avoid a networking meltdown. The good news is that the school is finally connected to the Internet; we can assist from Cambridge. |
|||
5: Firmware: Richard Smith fixed the “repeated game keys on resume bug” (Ticket #2401). During a resume, the main processor is not ready to receive key codes for about 100ms after the delivery of the SCI wakeup event. The EC dealt with this long delay badly. Fixing this should unblock ebook mode. Richard released a new EC code version that is available in Firmware Q2D09. This should show up in a signed Joyride build soon. |
|||
6. Battery issues: Richard did a large amount work on batman.fth; he added the ability to run a manual charge while watching voltage, current, and accumulated current registers. He received three laptops from the field with battery problems. One has a battery that just won't take a charge. The other two laptops won't recognize that the battery is present. Richard plans on tearing into these two machines next week to determine root cause. We need to discuss with Quanta what to do with problem batteries. |
|||
7. Schedules: Final testing for Ship2.2, Build 656, was held up this week as we tried to iron out some final details of the new process for “Unscheduled Software Release” (USR) (For those interested in process, please see [[Unscheduled software release process]]). |
|||
Update 1 is about to start the release process. Highlights include: |
|||
* suspend and resume is mostly, but not entirely implemented; |
|||
* Rainbow security is enabled; |
|||
* the Browse activity has been updated to use the technology in Firefox 3 Beta 2, which is significantly faster and better at memory usage. Innumerable bugs have been fixed. Performance is significantly improved. Memory and file leakage greatly improved. |
|||
Update.1RC1 (release candidate 1) is almost ready (Monday with luck). Joyride 1551 is very, very close to Update.1's contents, although it has some additional activities bundled in the base system that we do no plan to ship in Update.1. Please do test it, along with the new firmware version (Q2D09). |
|||
We will then start a testing cycle: |
|||
* suspend-and-resume cycling for reliability—during the run up to mass production the laptop was found to be able to reliably suspend and resume at least 50,000 cycles (the length of the tests we were willing to tolerate). We need to ensure there are not software or firmware regressions in this area. |
|||
* scaling tests—we need to ensure sane behavior of the systems in circumstances such as 300 children resuming their laptops all at once in the morning. |
|||
* verification of power use in different use states, on our power measurement systems; |
|||
* wireless driver testing and upgrade testing; |
|||
* testing with the school-server software; |
|||
RC2 (release candidate 2) will pick up additional translations and key bug fixes that missed RC1. The community is working to complete the Spanish translation, which was not complete by the string freeze date due to the holidays. There will therefore be a refresh of packages to complete the translations. Activity developers should only be picking up translations (and fixes for approved bugs). |
|||
RC3 (release candidate 3) is intended to pick up critical bug fixes discovered during testing, and is the first candidate that is a real candidate for widespread release. |
|||
Joyride will be reopened for the start of Update.2 development later |
|||
this week. |
|||
8. Testing: Chih-yu Chao has created the Update.1 Test page, which outlines the major features and bug fixes of this release and links to the test cases to be run and their results (See [[Update.1]]). The goal is to have enough planning and information around this release to be able to ask for help from the development and test community over the next two weeks to really hammer on the release. If we can do it, this will be the first release that gets organized, methodical community testing. Keep tuned to your email for more information (testing, devel, sugar mailing lists). |
|||
Yani Galanis is back from a short hiatus and has jumped right back into various wireless testing and debug activities. So far he is happy with David Woodhouse's rewrite of the wireless driver. He has fixed some problems with olpc-netstatus so it will accurate report the laptop's network and mesh configurations. He was able to get olpc-netlog working again (with Noah Kantrowitz's help) to zip up the logs, and olpc-netcapture to capture network traffic. |
|||
9. Support: This week, when all the laptops to Give One Get One donors were anticipated to have been delivered, Kim Quirk suggested we ask people to send email if they are still waiting for their laptop. When we hit 100 emails in less than a day, it became obvious that were dealing with a much larger problem than anyone at OLPC had imagined. This prompted some quick meetings between the companies involved in the order processing and distribution to try to get a handle on the scope of the problem and how to fix it fast. We learned about orders that could not be matched up between daily and monthly reports, orders that do not have enough information to ship, addresses that couldn't be verified, PO boxes, and miscellaneous other issues—about 10% of the total order volume. Adam Holt's support gang (up to 55 people now!) were inundated by mid-week with donor information requests, as was the Donor Services 800 number. Adam recruited two of the volunteers, Sandy Culver and Steve Holton, to join Greg Babbin and Adam to access the shipping database to help answer these requests. |
|||
Thanks to the entire support team who have been working day and night to respond to these extra requests! |
|||
10. Datastore: Ivan Krstić ran a Journal/datastore summit at OLPC this week. In attendance through out the week were Marco Pesenti Gritti, Tomeu Vizoso, Eben Eliason, Erik Blankinship, and Bert Freudenberg. A number of other members of the core team and the community joined periodically. It was a very productive week: the team nailed down almost all the details required before a first pass at implementation can begin. But before we do so, and while we continue conversations about the new API, Ivan will publish specification in the next few weeks for a round of public discussion. Look forward to a new object model, a refined set of interactions, and new features such as versioning and action-based journal entries. |
|||
11. Sugar activities: Arjun Sarwal incorporated sensor input into Turtle Art this week. One can control any aspect of the Turtle's motion based on sensor input. The next step is to integrate the concept into a Turtle Art “block” (See [[Measure#Sensor Input into Turtle Art]]). |
|||
Arjan has been talking to educators and teachers how they can organize some activities around the Measure Activity. He has also spoke with representatives of the Illinois Math and Science Academy (IMSA) chapter who have made a video documentary of experiments with sound using the Measure Activity (See [[Illinois Math and Science Academy Chapter]]). |
|||
Manusheel Gupta is investigating options for building a spreadsheet actvitiy for the XO. Python-powered spreadsheet (PPSS) seems to be a good choice for integrating into the Sugar environment, while perhaps pulling in some features from GNumeric. Eben Eliason will be discussing the ideas on the UI of the spreadsheet during the coming week. (See http://olivier.friard.free.fr/software/ppss/index.php). |
|||
Simon Schampijer fixed an error in the download handling within the Browse activity (Ticket #6018). Dan Williams and Simon finally think we have a good solution for “airplane mode”, e.g., operation with the radio off. A new network manager went into Joyride-1548 and the sugar rpm is building. |
|||
Simon does not really understand what happens in regard to reports that Browse is running slow after an update to Update.1 (Ticket #6046) (as opposed to a clean install). |
|||
Eva Schroth successfully conducted an interview using the XO laptop’s Record activity: after modifying some constants, she was able to record a one-hour conversation. |
|||
On the Etoys front, most of the core team members visited Poitiers, France this week; an IEEE conference called C5 was held. Many researchers, educators and Squeakers who are interested in collaboration and education met together and had interesting conversation. Bert, in response to Arjun’s Turtle Art demonstration, exposed some code in Etoys to enable the microphone level to be used as a data stream within scripts. |
|||
12. System software medley: Giannis Galanis contributed network fixes to olpc-utils that solve two Update.1 blockers. Phil Bordelon sent a tool to cleanup orphan Journal previews, which was also an Update.1 blocker. |
|||
FFM packaged up the python-gasp, an API wrapper for pygame for new programmers, which has just gone through the Fedora review process. |
|||
Chris Ball worked on OHM timing code, and with Reinier Heeres on fixing “ebook mode” to work inside Rainbow. |
|||
Reinier Heeres mostly worked on improving and build-testing of some bugfixes of last week. He also activated the new build announcer script, which needed a few minor fixes. For Sugar he fixed an issue with the stop button disappearing when rotating the screen (#5824), and for Read the eBook suspend problem (#1396). |
|||
Andres Salomon mostly worked on the touchpad driver this week and has made great progress on fixing problems, and improving its behavior. More importantly, Andres work made clear we should use the tablet sensor in relative mode by default, a conceptual breakthrough that had eluded us. A test kernel with the new driver is available here: |
|||
http://dev.laptop.org/~dilinger/master/kernel-latest.i586.rpm. |
|||
13. Presence: Dafydd Harries spent most of this week again working on the Jabber server component. A large part of this was working out how to effectively expose the person/activity information that the component will store over XMPP. Dafydd thinks he has a reasonable protocol; he plans to set up a test server that we can measure performance against. |
|||
Robert McQueen attended an introductory conference call with Ivan and Jon Herzog about collaboration and security; they are planning a specification-writing fest in late February. |
|||
Morgan Collett has been going through the wiki getting the references to Presence, Telepathy, and Tubes up to date, and working on a more |
|||
comprehensive reference for Presence Service. Morgan also modified Chat to make sure web links copied to the clipboard can be pasted in Write, Web location bar, and Terminal (Ticket #6066). That patch will land when the Spanish translation of Chat is complete. |
|||
Guillaume Desmottes continued work on Hyperactivity, a collaboration |
|||
stress-testing tool (Ticket #5817). It is now able to create/join/leave activities, set up and use D-Bus tubes. Guillaume started to test Salut using it and discovered some interesting bugs; most of them are already fixed. |
|||
14. Localization: Bernie Innocenti has been doing some integration work with Manusheel Gupta on Devanagari input support, but it seems there's more work to do, especially in the Write activity. Bernie met with Lidet Tilahun for a roundup on our Ethiopian support, and filed a bunch of bugs out of it. Lidet will contribute translations in Pootle. |
|||
Sayamindu Dasgupta reports that we have new teams for Dari, Fula and Telugu. He also tracked down a problem in Pootle that was preventing him from updating the PO files in the XO Bundled project. This has been quite difficult to trace down. The rest of the week was spent on more mundane things: |
|||
* he polished and debugged the various helper scripts that is used to run Pootle more smoothly; |
|||
* he helped Simon cross check the list of languages that are given as options by the sugar-control-panel (In the process, they identified a few languages that would require new locales to be added to glibc in order to be supported); |
|||
* he helped a number of users get started with the translations; and |
|||
* he added Slider Puzzle to Pootle. |
|||
Dr. Habib Khan reports that localization into Pashto is in final phase and that after some confusion on the Pootle server in regard to Dari and Farsi, progress in being made there as well. |
|||
15. Build system: Dennis Gilmore submitted patches to rpm enabling support for the AMD Geode. He has done some work on koji in preparation for supporting us. Patches will be submitted next week for upstream inclusion. These add Geode support and allowing us to pull upstream builds into our instance. Once initial support is in koji, Dennis want to add support to allow .xo building. This would result in a side effect that we get a .src.rpm and .noarch.rpm out of the process |
|||
We will need to have a git tree setup that will mimic Fedora’s cvs for things that we keep out of Fedora. |
|||
Dennis and Michael Stone looked at possibly using livecd-tools for Update.2: what would be involved in it and if its worth the effort. |
|||
This week, Michael talked with Bernie, Scott, and Dennis on ways to improve build infrastructure, offered occasional questions in the Journal |
|||
summit, and diagnosed the 'upgrade-server can't download builds' bug. |
|||
Update.1 is mostly synced up with Joyride. There are a few small pieces that need to be finished. As noted, we are very close to having an Update.1 |
|||
16. Content: The inclusion of the Doom activity in the wiki has sparked a healthy email discussion about content and filtering. Although heated at times, it has generally been productive. The gist of the debate revolves around the twin issues of (1) should OLPC be adjudicating what is appropriate content and (2) how should content be tagged such that children, parents, teachers, and others can make informed decisions about what content they access. |
|||
Suggestions have ranged from adopting “Terms of Use” such as those found on the Scratch website (http://scratch.mit.edu/terms) to fleshing out our guidelines ([[Activity guidelines]]) to making it easier for community members to search and sort favorites (requiring possible extentions to MediaWiki). |
|||
This discussion is by no means over, but please continue the thread on the olpc-open <olpc-open@lists.laptop.org> list rather than devel, which is intended for discussion of technical rather than policy topics. |
|||
17. OLPC Health: Arjun Sarwal continues his efforts to organize the community in medical and health applications around the XO laptop. He reports that we have a growing list of volunteers in three areas: |
|||
:(1) Creating a Library/repository of information that would be shipped on the XO laptop as part of the default software on it. This would be a ready reference for preliminary diagnosis of diseases and a reference for symptoms. This would also include general information on an array of topics such as hygiene, nutrition, balanced diets, etc. |
|||
:(2) Developing software that asks the user a series of questions and helps in a preliminary diagnosis. Links to useful websites and online portals. |
|||
:(3) Developing and using hardware peripherals that connect to the XO laptop. These include, but are not limited to the build-in camera (with the possibility of add-on optical elements; an EKG; and a pulse oxymeter. |
|||
18. Activity Handbook: Christoph Derndorfer reports that the first few chapters of an Activity Handbook are finished. The purpose of this handbook is to provide all the information needed in order to get started with software development for the OLPC XO. The current draft includes the first four chapters: |
|||
:1. Welcome to the Activity Handbook! |
|||
:2. Introduction to Sugar |
|||
:3. Preparation |
|||
:4. Sugar Basics |
|||
Christoph et alia will be expanding the handbook over the coming weeks to include chapters about using the Journal, collaboration, using the various XO input devices, and “Sugarizing” software. (Please see |
|||
http://www.olpcaustria.org/mediawiki/index.php/Activity_handbook and |
|||
http://www.olpcaustria.org/mediawiki/upload/a/af/Handbook_20080113.pdf). |
|||
19. Hello World: In a related effort, Chris Hager and Jaume Nualart report that they have created two new tutorials (during a “pizza-and-beer” coding session) for creating Activities with PyGTK, one of them using Glade (See [[PyGTK/Hello World Tutorial]]). |
|||
Chris and Jaume are using activity.py as a wrapper, which loads the code and GTK interface from gtktest.py. This way, very little code is required to get a PyGTK Activity running in Sugar—just six lines in gtktest.py—and PyGTK Activities can run as standalone versions on any Linux system by default. |
|||
Example Bundles: |
|||

|||
:http://wiki.laptop.org/images/0/02/Gtktest-glade.xo |
|||
20. Mongolia: Dave Woodhouse is in Mongolia setting up servers in two schools, which as been an educational experience. Firstly, the wireless penetration through the walls they have here to cope with temperatures of –40°C is fairly dismal—Dave reports that we are having to use a lot of active antennae to get the coverage we need. We're laying them out as if they were “normal” access points, to try to get coverage of all the rooms they'll be teaching the 2nd–5th grades in. Hopefully, the nature of the mesh will improve coverage. |
|||
To start with, each school will have five antennae, with two servers. That setup will be re-evaluated when it's fully deployed and tested in the classrooms. It is physically installed in one school so far, and fully |
|||
cabled (including CAT5 to the other rooms where they have computers). The other school should be similarly set up by the end of Monday. |
|||
21. Pakistan: Habib reports progress on the e-book project in Islamabad. Eight elementary text books based on curriculum of the Federal Ministry of Education, Islamabad have been made into e-text books. |

3. Ulaan Baatar: Enkhmunkh Zurgaanjin, Carla Gomez Monroy, Jan Jungclaus, and RedHat’s David Woodhouse are working hard to set up a structure that can provide sustainability to the project in Mongolia such that it can spread it throughout the country.

Manusheel Gupta is investigating options for building a spreadsheet actvitiy for the XO. Python-powered spreadsheet (PPSS) seems to be a good choice for integrating into the Sugar environment, while perhaps pulling in some features from GNumeric. Eben Eliason will be discussing the ideas on the UI of the spreadsheet during the coming week. (See http://olivier.friard.free.fr/software/ppss/index.php).
Simon Schampijer fixed an error in the download handling within the Browse activity (Ticket #6018). Dan Williams and Simon finally think we have a good solution for “airplane mode”, e.g., operation with the radio off. A new network manager went into Joyride-1548 and the sugar rpm is building.
Simon does not really understand what happens in regard to reports that Browse is running slow after an update to Update.1 (Ticket #6046) (as opposed to a clean install).
Eva Schroth successfully conducted an interview using the XO laptop’s Record activity: after modifying some constants, she was able to record a one-hour conversation.
On the Etoys front, most of the core team members visited Poitiers, France this week; an IEEE conference called C5 was held. Many researchers, educators and Squeakers who are interested in collaboration and education met together and had interesting conversation. Bert, in response to Arjun’s Turtle Art demonstration, exposed some code in Etoys to enable the microphone level to be used as a data stream within scripts.
12. System software medley: Giannis Galanis contributed network fixes to olpc-utils that solve two Update.1 blockers. Phil Bordelon sent a tool to cleanup orphan Journal previews, which was also an Update.1 blocker.
FFM packaged up the python-gasp, an API wrapper for pygame for new programmers, which has just gone through the Fedora review process.
Chris Ball worked on OHM timing code, and with Reinier Heeres on fixing “ebook mode” to work inside Rainbow.
Reinier Heeres mostly worked on improving and build-testing of some bugfixes of last week. He also activated the new build announcer script, which needed a few minor fixes. For Sugar he fixed an issue with the stop button disappearing when rotating the screen (#5824), and for Read the eBook suspend problem (#1396).
Andres Salomon mostly worked on the touchpad driver this week and has made great progress on fixing problems, and improving its behavior. More importantly, Andres work made clear we should use the tablet sensor in relative mode by default, a conceptual breakthrough that had eluded us. A test kernel with the new driver is available here: http://dev.laptop.org/~dilinger/master/kernel-latest.i586.rpm.
13. Presence: Dafydd Harries spent most of this week again working on the Jabber server component. A large part of this was working out how to effectively expose the person/activity information that the component will store over XMPP. Dafydd thinks he has a reasonable protocol; he plans to set up a test server that we can measure performance against.
Robert McQueen attended an introductory conference call with Ivan and Jon Herzog about collaboration and security; they are planning a specification-writing fest in late February.
Morgan Collett has been going through the wiki getting the references to Presence, Telepathy, and Tubes up to date, and working on a more comprehensive reference for Presence Service. Morgan also modified Chat to make sure web links copied to the clipboard can be pasted in Write, Web location bar, and Terminal (Ticket #6066). That patch will land when the Spanish translation of Chat is complete.
Guillaume Desmottes continued work on Hyperactivity, a collaboration stress-testing tool (Ticket #5817). It is now able to create/join/leave activities, set up and use D-Bus tubes. Guillaume started to test Salut using it and discovered some interesting bugs; most of them are already fixed.
14. Localization: Bernie Innocenti has been doing some integration work with Manusheel Gupta on Devanagari input support, but it seems there's more work to do, especially in the Write activity. Bernie met with Lidet Tilahun for a roundup on our Ethiopian support, and filed a bunch of bugs out of it. Lidet will contribute translations in Pootle.
Sayamindu Dasgupta reports that we have new teams for Dari, Fula and Telugu. He also tracked down a problem in Pootle that was preventing him from updating the PO files in the XO Bundled project. This has been quite difficult to trace down. The rest of the week was spent on more mundane things:
- he polished and debugged the various helper scripts that is used to run Pootle more smoothly;
- he helped Simon cross check the list of languages that are given as options by the sugar-control-panel (In the process, they identified a few languages that would require new locales to be added to glibc in order to be supported);
- he helped a number of users get started with the translations; and
- he added Slider Puzzle to Pootle.
Dr. Habib Khan reports that localization into Pashto is in final phase and that after some confusion on the Pootle server in regard to Dari and Farsi, progress in being made there as well.
15. Build system: Dennis Gilmore submitted patches to rpm enabling support for the AMD Geode. He has done some work on koji in preparation for supporting us. Patches will be submitted next week for upstream inclusion. These add Geode support and allowing us to pull upstream builds into our instance. Once initial support is in koji, Dennis want to add support to allow .xo building. This would result in a side effect that we get a .src.rpm and .noarch.rpm out of the process
We will need to have a git tree setup that will mimic Fedora’s cvs for things that we keep out of Fedora.
Dennis and Michael Stone looked at possibly using livecd-tools for Update.2: what would be involved in it and if its worth the effort.
This week, Michael talked with Bernie, Scott, and Dennis on ways to improve build infrastructure, offered occasional questions in the Journal summit, and diagnosed the 'upgrade-server can't download builds' bug.
Update.1 is mostly synced up with Joyride. There are a few small pieces that need to be finished. As noted, we are very close to having an Update.1
16. Content: The inclusion of the Doom activity in the wiki has sparked a healthy email discussion about content and filtering. Although heated at times, it has generally been productive. The gist of the debate revolves around the twin issues of (1) should OLPC be adjudicating what is appropriate content and (2) how should content be tagged such that children, parents, teachers, and others can make informed decisions about what content they access.
Suggestions have ranged from adopting “Terms of Use” such as those found on the Scratch website (http://scratch.mit.edu/terms) to fleshing out our guidelines (Activity guidelines) to making it easier for community members to search and sort favorites (requiring possible extentions to MediaWiki).
This discussion is by no means over, but please continue the thread on the olpc-open <olpc-open@lists.laptop.org> list rather than devel, which is intended for discussion of technical rather than policy topics.
17. OLPC Health: Arjun Sarwal continues his efforts to organize the community in medical and health applications around the XO laptop. He reports that we have a growing list of volunteers in three areas:
- (1) Creating a Library/repository of information that would be shipped on the XO laptop as part of the default software on it. This would be a ready reference for preliminary diagnosis of diseases and a reference for symptoms. This would also include general information on an array of topics such as hygiene, nutrition, balanced diets, etc.
- (2) Developing software that asks the user a series of questions and helps in a preliminary diagnosis. Links to useful websites and online portals.
- (3) Developing and using hardware peripherals that connect to the XO laptop. These include, but are not limited to the build-in camera (with the possibility of add-on optical elements; an EKG; and a pulse oxymeter.
18. Activity Handbook: Christoph Derndorfer reports that the first few chapters of an Activity Handbook are finished. The purpose of this handbook is to provide all the information needed in order to get started with software development for the OLPC XO. The current draft includes the first four chapters:
- 1. Welcome to the Activity Handbook!
- 2. Introduction to Sugar
- 3. Preparation
- 4. Sugar Basics
Christoph et alia will be expanding the handbook over the coming weeks to include chapters about using the Journal, collaboration, using the various XO input devices, and “Sugarizing” software. (Please see http://www.olpcaustria.org/mediawiki/index.php/Activity_handbook and http://www.olpcaustria.org/mediawiki/upload/a/af/Handbook_20080113.pdf).
19. Hello World: In a related effort, Chris Hager and Jaume Nualart report that they have created two new tutorials (during a “pizza-and-beer” coding session) for creating Activities with PyGTK, one of them using Glade (See PyGTK/Hello World Tutorial). Chris and Jaume are using activity.py as a wrapper, which loads the code and GTK interface from gtktest.py. This way, very little code is required to get a PyGTK Activity running in Sugar—just six lines in gtktest.py—and PyGTK Activities can run as standalone versions on any Linux system by default.
Example Bundles:
20. Mongolia: Dave Woodhouse is in Mongolia setting up servers in two schools, which as been an educational experience. Firstly, the wireless penetration through the walls they have here to cope with temperatures of –40°C is fairly dismal—Dave reports that we are having to use a lot of active antennae to get the coverage we need. We're laying them out as if they were “normal” access points, to try to get coverage of all the rooms they'll be teaching the 2nd–5th grades in. Hopefully, the nature of the mesh will improve coverage.
To start with, each school will have five antennae, with two servers. That setup will be re-evaluated when it's fully deployed and tested in the classrooms. It is physically installed in one school so far, and fully cabled (including CAT5 to the other rooms where they have computers). The other school should be similarly set up by the end of Monday.
21. Pakistan: Habib reports progress on the e-book project in Islamabad. Eight elementary text books based on curriculum of the Federal Ministry of Education, Islamabad have been made into e-text books.
ラップトップ ニュース 2008-01-12
1. G1G1 (ギブワン・ゲットワン・プログラム) で初の受益国はモンゴルでした。 ラップトップは次々と届き始め、Carla Gomez Monroy、Jan Jungclaus、Enkhmunkh Zurgannjin達をメンバーに含んだOLPCのチームが現地に派遣され初展開の手助けをしています。 今月下旬にDavid Woodhouseはスクール・サーバの手伝いをするためUlan Batorへ向かう予定です。
2. Las Vegas (ラスベガス): Nicholas NegroponteはCESで"TEchnology and Emerging Countries: Advancing Development through TEchnology Investments"と題するキーノート・スピーチをしました。彼はSeymour Papertのライフワークを基礎に学習、構成主義、そして、考慮に関しての考慮の歴史などの課題を取り上げました。
3. Cambrige (ケンブリッジ、マサチューセッツ州): WalterはX-Prize Foundationの創設者とチェアーマンでもあるPeter Diamandisと会い、提案されている二つのコンテスト: (1) low-cost rural water/power/communications station ();と (2) high-impact global learning intervention ()の開発などについて話し合いをしました。両コンテストは奨励金として$1000万の賞金があります。 両側のミッションははっきりとした共通点があるためOLPCはコンテストの目標と必要条件の設立に手助したいと申し出ました。
4. Las Vegas (ラスベガス): MIchail Bletsasは5th IEEE Consumer Communications and Networking Conference (CCNC)でキーノート・スピーチをしました。演説はXOのネットワーク・アーキテクチャーに関する内容でした。
5. In the news (): 今週OLPCに関するマスコミの記事では主に二つの課題:Intelの脱退とMicrosoftのXOに関する計画でした。 Intelの脱退は最終的にはすでにnauseumで討論された様に信用の欠如が原因です。Microsoftの計画についてはIvan KrstićのブログがOLPCの観点からその背景を説明しています (詳しくはこのリンクをご覧ください: http://radian.org/notebook/paradox-of-choice )。
6. Embedded controller (組込コントローラ): Richard SmithはSCI mask corruption problem (チケット #5467)で作業をしました。EC command implementationが原因の元なので極めて深刻なバグでした。Richardの証言ではとうとうグレムリンを倒したと思っているそうです。 元の実装ではロスしていたインタラプトに頼っていました。 その結果ECは最善でデータのプロセスが出来ず、最悪では完全にコマンドのプロセスを停止しました。この場合で解決方はこの不要なインタラプトをまるごと取り除くことです。Richardは変わりにpolling shemeを実装しました。現在コードは彼の全テストをパスして、最適化れていない状態でもスピードは早くなっています。 ホストはサスペンド前後に多くのECコマンドを出し、各ミリセカンドも欠かせないほど重要ですので、スピード高速化は大切です。Richardの頼みでは、彼の解決法をテストしてくれる参加者がいるならファームウェアをリリース Q2D08A (より高)にアップグレードしてくださいと申しています。
7. Firmware (ファームウェア): Mitch BradleyはQ2D08ファームウェアをリリースしました。長いリストになるくらいの'fit and finish'改良といろいろな細かいバグ修正がされています。 詳細な内容はwikiページの OLPC Firmware q2d08 を見てください。
8. SD Card Support (SDカード・サポート): 'Resume'(再開)時のSDカード性能はしつこい問題でした。 今週Mitchはその問題に取り込みました。 彼の測定の結果'resume'(再開)は使用しているカードによって25から200msの間にできます。7つのカードを使った平均的な数字は70msでした。
9. Batteries (バッテリー): バッテリーが充電してないと言うレポートが現地から数々届いています。 olpc-logbatから来るほとんどの内容は共通しています: XOはバッテリーが空っぽの状態でも満タンと報告して充電と停止する。 その結果ラップトップをバッテリー電源に切り替えると電量は15%以上ですが、電圧が最低レベル以下になり、警告もなしに停止してしまいます。あるケースではシャットダウンは数秒でするほど早く、また別の例では10から20分ほど持ちます。
Richardはユーザが充電量フィールドを'low'(少ない)に戻すことによって、ECが充電を始めるようbatman.fthにある程度の改良を追加しました。一人にユーザがこのユーティリティを試した結果: データによるとバッテリーの電圧は10秒の間に少なくて5V-6Vから7.4V以上の満タンしきい値まで飛び上がります。テストを三回くり返した結果、一つの実験でバッテリーは通常に充電し始めましたが、急に満タンに達しました。ECコードは正常に動いているようですが、何かがバッテリーの抵抗を急激に増加しているようです。この問題はバッテリーかまたは、XOの製造不良かどっちかです。この問題は充電回路の不良接続みたいに大変小さな事でも原因となる可能性があります。
10. School Server (スクール・サーバ): スクール・サーバ・ソフトウェア・プラットフォームはJohn Watlingtonによって複数サーバ・サポート機能が備えられている最中です。各サーバは三つの全ワイヤレスメッシュ・チャンネルのメッシュにネット通信を提供できます。1CC(ともっと静かなワイヤレス環境であるJohnの自宅)で2サーバシステムを手作りで設定して、全体的に起動しました。設定は自動化され、新スクール・サーバ・ビルドは初期テスト中で、この数日の間にリリースされる予定です。
急ぐ理由は一月にトライアルしているモンゴルの二つの学校にcommon libraryへのアクセスを提供したいからです。Active Antennaが大量に入手でき次第、別の場所でも配備を始めます。500名の生徒が通っている各学校は三つのサーバが700GBにもなる大きなlocal content libraryへのアクセスとバックアップ・ストレージをします。今週既に六つのサーバ(代表的PC製造者の最低額SOHOサーバ)をケンブリッジMAで再設定した後、トライアルへ出費しました。追加マシンは現地で調達中であり、その内テストされる予定です。
最新バージョンであるejabberd (2.0)がCollabraによってパッケージされ、スクールサーバ・ビルドに付け加えられました。ただ今テスト中です。 設定は手動的な部分もまだ残っていて、スケーラビリティと安定性についてはまだ深刻に考えるくらい疑問があるため、他の手段を探しています。
11. Testing (テスト): Chih-yu ChaoはJoyride 1489、1520、Update.1 681など色々なビルドのテストを行いました。テストではロケール・テスト、一時間スモーク・テスト、コンテンツ・バンドル(アクティビティとライブラリも含む)などがありました。彼女はさらにスクール・サーバになれるため作業を行い、サスペンド/再開用テスト事例を作りました。Kim Quirkはロケール、キーボード・テスト、Ship2.2 Build 656アップグレード・テストなどで作業しました。最新リリースに関しての情報はwikiのTest Group Release Notesページに載るので、このページはよく見張って下さい。
12. Wireless testing (ワイヤレス・テスト): 現在wireless firmware 5.110.22.p1 Build 674をテストしている最中です。 Build 674はDavid Woodhouseによるすべてのワイヤレス・ドライバー修正が入っており、おかげで安定性と性能が上がっているようです。Build 674におけるたった一つの問題点はSugarインターフェースでWEP暗号化されたアクセス・ポイントとの関連が出来ない事です (コマンドラインからは出来ますけど)。Wireless firmware 5.110.22.p1は、無線スキャン中に発生するリンクロス状態で現れるまれなワイヤレスハング修正をして、されに、内蔵ファームウェア・スレッドの相対的優先位の再アレンジもします。
13. Support (サポート): Adam Holtとボランティア・サポート・チームの方々達はシステムとドキュメンテーションに続けて力を入れています。さらにphone bank systemでも引続き作業が進まれています。毎週日曜日の午後四時(EST)にレギュラーのコールがあります。活動に参加する興味があれば、Adam (holt at laptop.org)宛に連絡を取ってください。
Adamによって主催された先週日曜日のサポート会議は大成功で24人の参加者が集まりました (詳しくは Support meetings をご覧下さい)。
会議などではゲストとして現れるディベロッパーが雰囲気を盛り上げます。Kim Quirk、Arjun Sarwal、Bernie Innocenti達が参加して下さって感謝しています。 週が終わるころにはサポート・リストに載っているメンバーの数は51人にも増えました。特にXOも持っていないのにペルーのリマから4日前に活動を始めたサポート・ボランティアのFrank Barcenasには大変良く活躍してもらっています!
さらにAdamはドキュメンテーションとQAのボランティアをリクルートしました。Felice GardnerとSJ Kleinもここで手を貸しています。Minnesota State UniversityのLee Tesdell教授と彼の生徒達は今後ドキュメンテーションの特定トピック上で我々と一緒に作業を進めるつもりです。同じようにAdamはArjunがする理科の先生達とカリキュラム・ディベロッパーのMeasureアクティビティへの感心を深める活動に手を貸しました。
またAdamは電話でチケットの解決をしました。特にRMAが必要、または、電子メールで連絡が取れなかった寄付者達と直接電話で連絡をしました。
AdamはUSAとカナダ各地で10人メンバーの修理センター設置へ向けて、我々のパーツ/修理ストーリーのナビゲーションで手伝いました。 このモデルは別の場所でも再現される可能性があります。
最後にAdamはMatthew O'GormanとJoe Phiganらと共にphone serverで作業しました。Matthewはボランティア練習が始められるようすぐにボイス・プロンプトの録音に取りかかるはずです。
14. Sugar medley (Sugarメドレー): Tomeu VizosoはUpdate.1リリースを見越してバグ修正をしました。彼はSugarシェル、ジャーナル、datastore、文書閲覧に重点を集めて作業しました。彼のほとんどのパッチはJoyrideビルドで既にテストされ、近いうちにUpdate.1ビルドに入ります。
Reinier Heeresはパレットが可視画面からはみ出ないようにするためにパレット・ポジショニング・ロジックを改良しました (チケット #5944)。Ellipsisの ('...')長ライン・サポートも入れました (チケット #4562)。 最後にイメージを使うPDFファイルのメモリー節約のため新バージョンevinceがビルドされ、fit-to-widthボタンがまた使えるようにするためTomeuによるパッチも加えられました。
Marco Pesenti Grittiはスタートアップ時にシステムをクラッシュさせるトルコ・ロケールが原因となっている問題を追跡しました。ワークアラウンドはビルドに入れました。実際の問題はNumpyハッカーによって追跡され、pygtkかPythonに潜んでいるようです。MarcoとReinierはパレット・ポジション問題に取り込み多重の修正をしました。Marcoはxulrunner 1.9 beta2をビルドしました。今からUpdate.1に入るほどの安定性があるかテストを始めます。彼はSimon Schampijer、Reinier、Tomeu達から着た数々のパッチ批評をしました [こいつらは凄いぞ]。出きるだけ早く緊急問題への修正をビルドに取り入れるため、たくさんのバグ・トリアージをしました。 regressionを避けるためすべてのJoyrideへの変更をテストしました。全体的に、特にブロッカーなどのSugarコア・バグのリストは減りました。そして、Mozilla 3.0でxpcomがデプレケートになったとき、まともなAPIにマイグレートする事が出来る様、「事を成し遂げたいなら、忙しい人を探せ」の精神にちなんでgtkmozembed maintenance upstreamはMarcoが引き受けました。
15. Software Medley (ソフトウェア・メドレー): Chris BallはUpdate.1最後のパワー・マネージメント機能、ユーザのサスペンド/再開に関連した「なぜ」と「どのくらいの頻度で」を記録するログファイルとバッテリー・ステータス情報の作業に取りかかっています。実際の場からログを集める事は現在のタイムアウトをさらに節操化してRichard Smithにも便利な電力データを与えます。
Andres Salomonはtouchpad driverといくつかのOLPCパッケージのDebianパッケージングもしました。
Bernie InnocentiはUpdate.1のためバグ潰しの作業に取りかかりました。特にpen-tablet故障、/home/olpcパーミッション問題、rootとolpcパスワード入力を不要にするためのコンソールへの自動ログインなどでした。さらにBernieはSJのモンゴル用ハードドライブ・イメージで手を貸して、ArjunのMeasureアクティビティの再デザインを手伝いました。彼とWalterはスペイン語とポルトガル語のコンソール・キーマップのデバッグをして、Albert Cahalanは我々が近いうち組み込みたい質の良いコンソール・フォントを 用意してくれました。
ペット・プロジェクトとしてBerniaはSoundTrackerと名乗る'oldskool'アクティビティのポートを開始しました。彼は手伝いを求めるため原作者と連絡をしています。
David Woodhouseは近いうちにアップストリームに届き2.6.25に入るuninfsのパッチを調べました。その内にFedoraカーネルに入ると思いますので、もう少しそれで遊んでみます。それらは下層にあるファイルシステムに何も変更もなしで使えるます。それで、whiteouts (上層のファイルシステムが下層にあるオブジェクトをアクティブに削除する)は少しハックになりますが、一応修正できます。 デザイン的にファイルシステムからなにも特別に必要としない事は良い考えで、きれいに出来ると思い、ただ今まで誰もしなかっただけです。
DaveはいやいやながらもJFFS2がプリントするCRCフェイルメッセージ(ほとんど無害)のログ・レベルを減らしました。 root専用書き込みスレッシュホールドを取り入れ、sysfsを通してすべてのスレッシュホールドを表に出す必要があります。
チケット#4013にあるTomeuのコメントによるとDaveのSD一時的修正はとても役に立つかもしれません。 デバイスは何処かへ消えていき、その後に新しい物の様に見えるデバイスがサスペンド/再開で現れます。デバイスでrootfsを走らせていて、かまたは、サスペンド中にオープンファイルがあったらあまり役に立ちませんが、use casesの場合は何らかの助けになるようです。再開時のカード検出遅延に関してはMarvellと一緒に調査する必要があります。彼らの主張では我々の測定ほど長くかからないと仰っています。
16. Build system (ビルドシステム): ReinierはPythonで書いた新ビルドアナウンサー・スクリプト作成(http://dev.laptop.org/~rwh/announcer) に取り込みました。Bert Freudenberのスクリプトより改良された機能は、まだビルドに現れていないパッケージバージョンのチェンジログ・エントリーを回収出き、KojiからRPMのチェンジログを直接手に入れる事です。Dennis Gilmoreは失われたSRPMSの追求と物事をなるべく良くするため、今週のほとんどを費やしJoyrideとUpdate.1のシンクをしました。 また彼はFudconでOLPCに関して人々と話をしました。G1G1参加者も結構いて、XOに大きな感心を見せていました。Dennisは週末にXOの講義を開くそうです。
週の初めの出来事で、Jim Gettyはビルド問題で怖い目にあいました。決して起きるはずがないのにUpdate.1にJoyrideより最新のパッケージが入っていました。Dennisが追求した結果、問題はミスタギングだと判明しました。真剣にテストが可能になれるほどUpdate.1に近い両立した繁殖可能なビルド完成はとても近くなっています。
17. Presence service (presenceサービス): Guillaume DesmottesはGabbleでOOBをサポートするのに必要なtransport re-negotioationをするJingleプロトコルのプロポーザルをデザインしました (詳しくは http://telepathy.freedesktop.org/wiki/Jingle-renegotiation) 。 彼はコラボレーションstress-testingツールであるhyperactivityの実相を始めました (チケット #5817)。
Morgan Collettは電波が間違った順序で受信される問題が原因となりbuddiesがsharedアクティビティでクラスタ出来なくなってしまう、presenceサービスのバグ修正を完成させました (チケット #5368)。 パッチはSugarのsnowflakeレイアウトでアクティビティに動かした最初のbuddyは隣に現れますが、その後のbuddyはただmesh viewから消えてしまうUI問題を表に出しました。アクティビティから去ると再び現れます (チケット #5904)。 さらにMorganは他に2つほどのpresenceサーバ問題で作業しました。Mesh viewの空っぽ名前とhex-key名前です。
18. Localization (ロケール化): Sayamindu DasguptaはいくつものアクティビティやSugarなどで作業を行っているボランティア翻訳者がEtoysでも作業が出来る様にするため、Etoys用のPootleプロジェクトを立ち上げました。 彼はボランティアに翻訳してもらうためPootleにmemorizeアクティビティを加えました。 Pippyでスペイン語に防ぎを与えていた問題を修正しました (チケット #5504)。さらに、ベンガル語 (インド)、カタロニア語、ポーランド語翻訳チームの設立などの手伝いをしました。
パシュトウ語とダリ語のロケール化は引き続き進んでいます。Dr. Habib Khanのレポートによれば彼のチームはロケール作業を共に行うためInternational Islamic Universityのアフガン卒業生達と交流したそうです。彼らはプロジェクトに熱心に取り掛かりましたが、期末テスト期間が始まり1月20日まで続きますので、我々が期待してた初期完成はスケジュール通りにはなってくれない様です。
Arjun SarwalとBernieはLohit Hindiフォンとを使いDevanagariキーボードのテストをしました。キーボードとフォントレンダリングはうまく行っている様です。Lohit Hindiフォント・パッケージはUpdate.1に入れ込まれる予定です。
19. Wireless driver (ワイヤレス・ドライバー): Dave Woodhouseはlibertas driverで作業をしましたが、前のパッチが着陸してほこりが沈むまでは、本気ないじりは始めないそうです。ほとんどはクリーンアップだけです。本当と修正と危ない作業はもう過去の話です。彼のテストでは何もなかったサスペンド/再開ですが、既に二つもバグレポートが出ているので、Daveはドライバーに何らかの間違いがあると想定しています。
さらにDaveは来週モンゴルへ訪れるのでスクール・サーバの件などそこで一体なにが待ち受けているのか(-20°Cの冷凍意外に)をとことん調べています。
20. Rainbow (Rainbow): Michael Stoneは多くのバグを修正とパッチの提供をしました。Bernie、Phil、Simon、Marco達とそれってに我々は以下を含むUpdate.1のRainbowですべての知られている問題の解決、改良、ワークアラウンドを提供しました:
- the 'rainbow spool persistence bug' (Ticket #5033);
- the 'SSL failure bug' (Ticket #5489);
- the 'orphaned files bug' (Ticket #5637);
- the 'uid reclamation bug' (Ticket #2527);
- the '/home/olpc permissions bug' (Ticket #5320); and
- the 'sudo vs. su bug' (Ticket #5537).
他にMichaelはorphaned previewsバグでPhil Bordelonの手助けをしました (チケット #5929)。 そして、DanielとChih-yuにUpdate.1に入る予定のisolation機能のテストプランの作成開始のため、我々が実装するactivity isolationの概要を与えました。
Marcus Leech (Nortel)からの貢献は欠かせない物でした。
21. Activities (アクティビティ): Joshua MinorはSpeakと名乗る新しいアクティビティを作りました。これはXOラップトップのしゃべる「顔」です。タイプした物はすべてXOのスピーチ・シンセサイザーespeakを通し言葉として出て来ます。声のアクセント、速度、ピッチの他、目や口の形なども調節できます。これはスピーチ・シンセサイザーの実験やタイプ練習、また、XOに変な顔をつけるとかをする楽しい実習になります。詳しくは Speak をご覧下さい。 (Joshは次の方々に感謝を申しております:Arjun Sarwal、Hemant Goyal、Bernardo Innocenti。)
Arjun Sarwalは引き続けてMeasureアクティビティの改良を行っています。彼はグラフ追加を簡単にするとか、viewを増やすとかをするため、コードをスケーラブルにする作業をしています。 大きい描画エリアと多くあるデータのリアルタイム・プロセッシング、また、ファースト・レスポンス・タイムの組み合わは最適化と実験バランスのチャレンジ(そして興味)となります。
Wiki内のMeasureページはXOにつなげる独自のローコスト・センサー作り方の簡単な説明が載っています。 Measure学習アクティビティで今月のフレーバーはTemperatureです。Arjunは教育者/先生/愛好家などにページに載っている説明を元に独自のローコスト温度センサー・プローブを試しに作って下さるよう願っています。問題がある時は(arjun AT laptop.org)まで連絡して下さい。
それに関連した活動でArjunはOLPC-Health interstグループの設立に興味を持っています。 XOを中心に医学と健康に関するアプリ開発に興味のある方はLibraryメーリングリストに加わって、Health wikiページ (Health)のボランティア・セクションに名前を記入してください。参加者はハードウェア・ディベロッパー、プログラマー、医者、生物学者など構わずご招待致します。一月最後の週に会議コールをする予定です。
22. E-books (E-books): Dr. KhanのレポートではFederal Ministry of Education、イスラマバードのカリキュラムに載っているすべてのテキストブックをe-bookに移す作業プログレスの情報が報告されています。下記のFederal Ministry of Education英語とウルドゥ語medium用Grade Iテキストブックが完了しています:
- My English Reader for Grade I
- Islamic Studies (Shaoor-e-Islamyat) Grade I
- Social Studies for Grade I
- Science for Grade I
これらのテキストブックはDepartment of Education、IIUによる評論を待っています。提案を元にXO libraryでも利用できる様にします。
23. Curriki: Lauren KleinとSJ KleinはJoshua MarksとCurrikiグループ・ディベロップメント・チームと共に彼らにサイトにあるOLPCコレクションのスペースとインタフェースのデザインを開始しました。Joshuaはgrops機能をロールアウトしています。これは個人ポータルのカスタムデザインを来週までに可能にして、"compile for XO"ボタンの実装とOLPCスタートページを簡単にします。
