1. Active antennae: Another 90 prototype active antennae should be available in a couple of weeks, followed shortly by a large shipment of pre-build antennae scheduled to arrive in three or four weeks. The initial run will be used mostly for field testing, with the majority of the units going to Uruguay. They will be labeled as “engineering samples—not for sale.” We now have an update procedure for the prototype antennae that allows them to stay connected to a server. (These had been built with firmware that placed them in stand-alone mesh-repeater mode too quickly, thus requiring them to be connected only after a server is up and running.) See [[Active Antenna Reprogramming]]. |
|||
2. Firmware: Mitch Bradley fixed a problem with OFW reading JFFS2 images (Ticket #6291) encountered when using the multicast update method. (This was one of the bugs uncovered by David Woodhouse in Mongolia last week.) |
|||
3. School server: Power continues to concern us. John Watlington realized that the off-the-shelf server prototype he was looking at for rural environments actually came with a 19VDC power supply, not a 12VDC one. While 12V supplies are available, they don't work well with unregulated 12V input. With such a 12V supply, the server prototype required around 16W while idling, and up to 26W when running three meshes and doing heavy disk accesses. The current power consumption requires four hours of pumping on a Weza to keep the server operating for an eight hour day! We will also have to greatly improve the power consumption when the machine is idle to have any hope of the servers being left running when the schools aren't in session. |
|||
4. Embedded controller: Q2D10 had some battery charging regressions, so Richard Smith backed out the change that speed up the battery-processing state machine; that fixed the regressions. The EC command saga continues: a machine was brought in that had total EC command failure, yet after Richard started examining it, it magically cleared up. After a long spell of trying to reproduce the problem, Richard made a significant discovery: it appears that if the input-buffer-full (IBF) flag is set and the power to the processor is cut, then the EC can go into a state where it thinks that a constant stream of data is being received. This results in the IBF flag getting reset just a soon as you clear it. Richard is still researching/understanding the issue, but this may explain why the previous interrupt-driven protocol was having so much trouble. |
|||
5. Automated charging testbed: Richard has set up an automated charging testbed: four XO laptops are now in a suspend/resume testbed; these laptops are connected to a switch such that every three hours, a supervisor machine turns off the external power to each of them. Each laptop is running a small script that watches for when the battery capacity gets low. When low battery is detected the XO laptop turns its power back on. |
|||
6. Power profiling: Now that we have automatic power management in the Update.1 builds we no longer have a simple power profile for measuring battery life. To get an accurate indication of what the “real world” battery life will be when power management is doing automatic suspend/resume we need to know what the power profile looks like while using the machine. We are gathering data from different use cases by running the olpc-logbat script while using the XO laptop: olpc-logbat samples the battery discharge information every 10 seconds. We can use much more data—please run the script yourself and send us the CSV files that it generates. |
|||
#charge up the battery; |
|||
#run the sugar terminal activity; |
|||
#run olpc-logbat in the activity; |
|||
#unplug from ext power; |
|||
#use the laptop normally. |
|||
7. Testing: Much thanks to Chih-Yu Chao, whose last full time day helping with QA and testing was Friday. This week she was focused on providing test cases, structure and encouragement to the community in our push for Update.1 testing. To help out, please review and execute test cases listed in the wiki ([[Update.1]]), or choose some test plans ([[Category:Test plans]]) and then post the results ([[Update.1#Test_Results]]). We can really use lots of help! |
|||
Yani Galanis has been testing avahi, telepathy, and general mesh capabilities with the latest Update1. He has helped open up some discussions of what we have today, what we would like in the future, and how we might get there. There is still some design work, coding, testing, and discussion needed in this area as some of our real deployments are pushing at our limitations. |
|||
8. Support: This week Nicholas Negroponte sent out a letter to all donors who have not yet received their laptops apologizing for the problems and explaining some of the on-going issues. The remaining laptops should be shipped by the end of March. Many people can now track their order directly at the laptopgiving.org webpage, which has started to reduce the number of emails to the support team. |
|||
There was a good discussion on Friday with Mel Chua, Nicki Lee, SJ Klein, Adam Holt, Walter Bender, Kim Quirk on the topic of grass-roots repair centers—more on that theme next weekend. |
|||
Adam organized another Sunday meeting among ~20 support volunteers, with guest speaker Manusheel Gupta talking about entrepreneurship among children with XO laptops. The ~60 support volunteers continued to fend off shipping/billing questions this week by the 100s. The number of questions almost doubled in January; the percentage of questions pertaining to donor services increased four fold: almost a 700% increase from December!! |
|||
But there is lots of good news: even with the continuing onslaught regarding donor services, we've lowered our unresolved tickets queue from 500+ to about 350—and we have received many profuse thank-you letters from donors who had been fed up to the gills at being abandoned until now. Even with the increase in volume of laptops deployed, there was no corresponding increase in questions about connectivity, Flash support, or help getting started. It is safe to say that once people get their XO laptops, they are managing quite well. |
|||
Our thanks to dwa (David Aquilina) and alc (Alan Claver) and countless other volunteers working so hard to be supportive towards all. |
|||
9. Roadshow: Dave Woodhouse, Bernie Innocenti, and Jim Gettys attended Linux Conf Au (LCA), which is considered by many to be the best Linux conference in the world at this time. The LCA organizers and OLPC combined to distribute a 100 machines to developers at the conference. (The lack of G1G1 in Australia is, of course, frustrating to people here.) |
|||
10. Presence Service: Guillaume Desmottes ran more tests on Salut using “hyperactiviy.” He fix various memory leaks and other issues and helped Marco Gritti to use hyperactivity to debug a Sugar UI bug. He also reviewed Sjoerd Simons's Gibber DNS resolver branch; released telepathy-salut 0.2.2, which fixes some OLPC related issues (Ticket #6271); and discovered and tracked more Salut crashers (Tickets #6303, #6309, #6310). Morgan Collett used his new Fedora superpowers to build RPMs for Presence Service and Salut via koji. He has been working on Presence documentation and tested builds and |
|||
presence service/telepathy related fixes. Sjoerd fixed several bugs in telepathy-salut that were discovered thanks to the hyperactivity stress testing tool. |
|||
11. Sugar: Simon Schampijer worked with Marco Gritti and Sayamindu Dasgupta debugged and found the cause of the “Browser being slow after an update from ship.2 (653) to update.1(690)” issue (Ticket #6046). It turned out that timestamps of fonts were set in the future. xulrunner does check if fontconfig is up to date and if it is unsuccessful the fontconfig is reinitialized and the whole thing repeats itself again. The resulting loop is causing the slowdown. Sayamindu has provided a new fontconfig rpm which checks if mtimes are in the future and print a warning but does return true so Browse will not be slowed down. In addition Michael Stone has released a new rainbow-0.7.9 which symlinks '~/.fontconfig to ~/instance'. Simon also provided a patch that releases exported dbus objects (Ticket #6127), which is important for activities that run in a single process, such as Browse. |
|||
12. Etoys: The Etoys team is working toward delivering a package for Update.1. Scott Wallace, Bert Freudenberg, and Yoshiki Ohshima fixed various lingering bugs in the system. Ted Kaehler and Kathleen Harness are revising the Quick Guide system and contents. From the effort, the candidate version for Update.1, Etoys-77.xo, was created. Takashi Yamamiya and Korakurider keep working on the translation issue. Takashi discovered that Pootle cannot merge large sets of translations fast enough. He is looking into the issue. The interactive geometry system by Hilaire Fernandez is improved. Now, it is packaged as a .xo bundle ([[DrGeo]]). It contains the translation framework by Korakurider and others for activities written in Etoys. |
|||
13. Spreadsheets: Dan Bricklin and Luke Cross are working on a port of the Sweet SocialCalc Project to the XO laptop. SocialCalc is a highly functional spreadsheet implemented in JavaScript. (To date, 39 functions have been developed: ABS, ACOS, ASIN, ATAN, ATAN2, AVERAGE, COS, COUNT, COUNTA, COUNTBLANK, DEGREES, EVEN, EXP, FACT, FALSE, IF, INT, LN, LOG10, MAX, MIN, MOD, NA, NOW, ODD, PI, POWER, PRODUCT, RADIANS, SIN, SUM, STDEV, STDEVP, TAN, TODAY, TRUE, TRUNC, VAR, and VARP.) Manusheel Gupta is helping them with the Sugar port. The first pass will be to leverage a general application that supports activities written in JavaScript, with Python-based Sugar binding. |
|||
Another approach to developing a spreadsheet activity is to begin from the GNumeric code base. Manu is working with Jody Goldberg and Eben Eliason to port a simple version of GNumeric to the Sugar environment. |
|||
14. Sensors and learning: Arjun Sarwal incorporated Spanish-language support into Turtle Art with Sensors and made a slightly modified icon of the original Turtle Art icon. The activity is now in Joyride Builds and is identifiable by a slightly modified icon of the Turtle. Arjun spent time discussing with Edward Baafi of the FabLab and Aaron Miller of MIT Media Lab’s Lifelong Kindergarten regarding how sensors, apart from acting like an interface to the physical world, could impact the XO laptop deployment communities. Aaron is working on integrating sensors into “Scratch” (which is now available for download from [[Activities]]); Edward Baafi is interested in exploring how general-purpose boards, which include sensors as well as I/O, can be used in conjunction with the XO laptop. Arjun continues to explore the wonderful possibilities of $2 sensor experiments through the XO laptop’s analog-input port. Documentation of the session with youth at FabLab Boston is in the wiki (See [[Measure/Turtle]]). |
|||
15. OLPC Health: The OLPC Health initiative has gained good momentum. There are active discussions on the Library mailing lists and the wiki pages have also started to take shape (See [[Health]]). A vision document ([[Health/vision]]) is also in the works. The list of group of advisers to the OLPC-Health initiative includes Josh Hehner, Jim Hopper, Sv Subramanian and Ichiro Kawachi. More detailed introductions of the advisers will follow soon on the Library mailing list. There is a conference call on the 10th of Feb at 1pm EST. People are invited to propose agenda items by posting on the Health wiki pages. |
|||
16. Ethernet: Michail Bletsas hosted Jonathan Hsu, founder and CEO of Zoltantech at OLPC this week. He makes a very small, elegant and low cost (< $10) USB-Ethernet adapter that works well with the XO; it could be very useful to developers and advanced users. |
|||
17. Localization: Arjun, Manu, Bernie, and Walter worked through integration of patches for Afghan (including Dari, Pashto and Uzbek variants), Mongolian, Ethiopian, Nepali, and Italian keyboard layouts. All of them (except Italian and Nepali) are expected to be integrated into Update. Sayamindu Dasgupta reports that we have new teams for Italian, Marathi and Sinhala. Continuing on his recent efforts with QA and testing with respect to local-language support, Sayamindu has added notes in the wiki on how to utilize the translation testing features in our web-based translation management system, Pootle ([[Localization/Testing#Testing_the_PO_files]]). |
|||
He also discovered a few cases where Pootle can become very slow, and discussed these with the upstream developers. They have suggested a few solutions; he is trying to implement them in our deployment. The shifting of Pootle to the new server had caused some issues to crop up with the Git integration; Sayamindu managed to track them down and fix them. |
|||
Localization of OLPC for Afghanistan: Dr. Habib Khan reports that they have started localization of Etoys (a major project, as it contains 23,000+ strings). They have done some work in Urdu localization of Etoys and almost 1000 strings are translated into the Dari language. The next step is localization of Etoys ino Pashto. |
|||
OLPC User Manual: Usman Mansoor “Ansari” and Sohaib Obaidi “Ebtihaj” continue their efforts; translation of the user manual into the Dari language is complete and is now under review; the review of the translated version in Pashto is 90% complete. |
|||
Localization Tests: Habib also reports that they have successfully tested the Urdu localization .po files that Pootle generated on one of their test machines. There are some small issues with some of the character bindings; in addition, they are testing it with Dari and Pashto languages. The target is to have three XOs completely localized inUrdu, Dari, and Pashto by next week. |
|||
18. In the community: On invitation by the Computer Society of Pakistan (CSP), Habib made a short presentation on OLPC to the participants and distributed a CD containing presentations on OLPC. The members of CSP are the leaders of Pakistani IT industry. |
|||
Mike Lee reports that the monthly grassroots OLPC Learning Club in Washington, D.C. had a record 48 attendees (including several children and teens) this past Thursday night at Greater DC Cares (See http://www.olpclearningclub.org). Their host, Curtis Cannon, talked about how DC Cares will use the seven laptops they acquired through a holiday fundraising effort called Technoliday organized by Peter Corbett to support their program of pro bono technology consulting for social change. Justin Thorp demoed the Library of Congress' World Digital Library, to which he contributed development effort. Mike demonstrated accessories for the XO including auto adapters, solar panels, the Weza foot treadle charger, clip on sports viewfinders for the camera and the new ZoWii miniature USB Ethernet adapter in OLPC green. Two iLite USB keyboard lights and an auto power adapter were raffled off. Attendees stayed for another hour to mesh. The first Mass XO Meet-up was also held this week (in Cambridge). |

ラップトップ ニュース 2008-01-26
1. Davos, Switzerland (ダボス、スイス): Nicholasの報告によると通常World Economic Forumは嵐のようですが、今年は特別にハリケーンとなり、報道関係からのOLPCへの感心はまるで突風のようでした。Intel結界事件への注目は議論の対象として予想以下でした。OLPCの存在その物が驚くべき物として取り上げられました。伝統的に土曜日の朝に行われるブレックファースト・ディベートでは過去にOLPCとIntelがお互いに激しく戦い合いましたが、今回Craig Barrettは出席しませんでした。
2. OLPCとBrightstar、Quantaも含めてG1G1プログラムのためにある在庫と生産スケジュールの見直しを行っています。現在供給にギャップがありUSキーボードとACアダプターの要求がある限り、残りの「Get」ラップトップの出費は3月になりそうです。
3. School server (スクールサーバ): John Watlingtonのレポートによるとスクールサーバ・ソフトウェア開発は着実に進んでいます。ウェブキャッシュとマイナーバグ修正を含めた新リリースはテスト中で月曜日までには用意されてるはずです。このリリースはウェブフィルターも含まれ、現在はDansGuardianを選び、簡単に使えるようにしました。フィルタの内容は各国々が決め調達しまが、出発ポイントとして出来上がったフィルタを調達できるいくつかの商業サプライヤーのリストがあります。次の開発は短期間ラップトップ・バックアップ・ソルーション、activationサーバ、今週モンゴルで役に立った'multicast updater' (マルチキャスト・アップデーター)のパッケージ化などに重点を置き、さらにコンフィギュレーションの使いやすさの改良もある程度手を入れます。
モンゴルでメッシュと現在のコラボ・ソフトウェアの限界が痛いように明らかになりました。そこではバグ #5335 (思ったより多かったmDNSトラフィック)と #5007 (メッシュがマルチキャストをリピートしすぎ) を持っているラップトップが完璧にも嵐の原因となり他の人たちのネットワーク使用を防ぎます。我々はメッシュの性能を改良し続けますが、一体どの様な環境で何のネットワークインフラを導入すべきかを明確に書したガイドラインが必要です。一旦生徒の密度が限界を越えると、有線バックボーンと従来アクセスポイントが必要になります。
4. Embedded controller (組込コントローラ): Richard SmithはUpdate.1のECコード変更を終了後PQ2D10をリリースしました。これはシステムファームウェアQ2D10に繰り込まれました。このファームウェアは安全にサスペンド/再開をすることができるはずで、ラップトップをサスペンドから起こすときの'games key events'の取扱いも改良されています。Richardが言うにはバグ(チケット #6105:“New EC firmware in Q2D09 seems wonky”)は全面的にテストされるまでは修正されたとは言えないそうです。キーボード取扱いコードはとても複雑です。その他にRichardはJoyrideに入れるためにビルドされるbootfw RPMパッケージ用ファームウェア・ビルドスクリプトの改造をしました。
5. Batteries (バッテリー): Carla Gomez Monroyのモンゴルから来た報告ではバッテリーは思った程長持ちしていないとの事です。最初に思いついた原因は寒さでした。RichardはCarlaにolpc-longbatを通しデータを集めてもらい冷凍庫(ウランバートル程寒くはありませんが)で独自のテストをしました。このデータとGoldPeakデータシートの内容からでは-20℃から-40℃の底気温ではバッテリーは使い物にならない事が明らかになりました。この究極な低温は電圧アウトプットをかなり落としてしまいます。それで電力が50%辺り以下になると電圧が低すぎになり底電圧カットオフが起動してラップトップが停止されてまいます。Richardが心配するのは子供達がXOラップトップをサスペンド中(電力散逸がもっとも低くself-heatingに影響あり)に外へ持って行き停止してしまう可能性があることです。バッテリーのベンダーと話し合わないといけないのは、非常に寒くなった時に底電圧カットオフを軽減しても良いのかの質問です。一体これでバッテリーはダメージされるのでしょうか?
6. Testing (テスト): Chih-yu Chaoは今週中Update.1テストと'test-case'(テストケース)の開発をしました。テストケースはパワーマネージメント、サスペンド、ebookモード、アクティビティ'isolation'、ネットワーク・マネージャ、スケーリングテスト、コンテンツ・バンドルのローカライズがあります。ぜひこれらのテストケース (Update.1) をレビューしたり試してみたりして下さい。さらにShip.2.-656の最終テストの一部として'automated olpc-update feature'(自動olpc-update機能)もテストされました。
Dennis GilmoreはUpdate.1のリリース候補としてUpdate.1 Build 690をリリースしました ( http://pilgrim.laptop.org/~pilgrim/olpc/streams/update1/build690 をご覧下さい。) ぜひこのビルドを徹底的にテストしてください。このビルドにWEPとWPA問題があるとの報告があり、これらの問題は今後のリリース候補で解決されるはずです。
7. Schedule (スケジュール): G1G1問題、モンゴル配給、OHMとセキュリティ・バグにリソースが転用されているためUpdate.1リリース日は遅れ始めています。現在のスケジュールはディベロッパーwikiのRoadmapページに載っています ( http://dev.laptop.org/roadmap )。トリアージで手伝いが必要なので、このリリースに割り当てられた重大バグとtestingから流れてきたバグもついでに見てもらうと大助りです。さらに重要なのは、テストすることで、ぜひ手伝って下さい!だれも探してくれないと一体どこに重大バグが潜んでるのか知ることはできませんので。
8. Support (サポート): Adam Holtと彼のサポート・グループは引き続き「私のノートPCいつ届くの?」問題と戦っています。我々は毎日パートナー達と連絡をを取り注文の数、内容、生産情報、出費情報を集め、電子メールの著作やdonorポリシーの作成もしています。
モンゴルでは、Carla Gomez MonroyとDave Woodhouseが1000機にもなるラップトップの導入とRF接続性に関連した問題との戦い、そして工場でビルドをアップデートする時間が無かったのが原因でウランバートル宛の初期注文は急ぎすぎてしまい数多くのラップトップをアップグレードしないといけない状況などがありました。その上に子供たちに配給されたラップトップの初サポート問題も現れ始めています。
Adamは再びサポートチームの日曜コール会議を提供しました。今週のゲストスピーカーはつい最近ナイジェリアへ訪問したときのOLPC観察について話したAnders Mogensenと新しい電力オプションとそれを配備したときに一体どうなるのかの影響に付いて話をしたBelkinから来たJoshua Bealなどが出演しました。彼らが貢献してくれた談話や質問への返答は出費混乱で落ち込んでいたチームにとってはもっとも必要な時に来てくれた大切な気分転換となったでしょう。
AdamはG1G1から山のように来る支払い請求/出費問題に効率的に対応できるようにするためサポートチームの再編をしました。再編のフォーカスはすべての状況に当てはまる一つの良い返答で、もっと詳しいオーダートラッキングも含まれます。Sandy Culver、Steve Holton、Greg Babbing、Guynn Prince達はRMAと「出費不可能」で非常に多く手伝ってもらいました。
9. Satellites (サテライト): Michael BletsasはThomas JacobsonやRoland Burgerと共に2月27日にワシントンDCで公開されるSatellite 2008ワークショップに出席します。タイトルは“Low-cost satellite Internet infrastructure to support education in remote and developing regions.”(リモートと発展途上地区の教育サポートをする低価格サテライト・インターネット設備)。このインフォーマルなワークショップの目的はドキュメントデザイン要件とそれの正当化;現在存在する製品がどこまで補うことが出きるか;そしてさらに開発の必要な部分の調査です。参加する希望のある方は'exhibit-only'手続き(VIPコードBOFを使うと無料でできます。)をするだけで良いです。
10. Mesh (メッシュ): 500機のラップトップを同じ屋根の下に詰め込む事は困難(従順ですが)なエンジニアリング問題です。この様な配置テストはやったことがありません。それにモンゴルはテストするために適した場所でもありません。それでも常識的に物を考えれば物事は結構進みます。ラップトップのセッティングを密集に改良した後(ソフトウェア開発スケジュールでは優先しませんでした)、スクールサーバに当てるXOラップトップは180(メッシュモードでは各チャンネル60)に制限しました。しかしながら、同じ屋根の下にスクールサーバの数を増やしてもスペクトルは増やさないので直接容量が増えるとは限りません。スクールサーバは何百ドルの費用が掛かりますので、マルチサーバよりも通常の低価格アクセスポイントを設置した方が経済的です。(OLPCメッシュ実装はまばらぬ配備での接続時間をできるだけ引き伸ばすのと(例えばカンボジアの村に住んでいる子供やルワンダの田舎にある学校など)アクセスポイントとの接続性を簡単にして、そしてそこから接続性を取り離すのが目的です。)
11. OLPC infrastructure (OLPC設備): Ivan Krstićは公衆向け設備 (wiki、static web、git、trac、hosting、mail、mailing lists) を完全にオーバーホールしました。体制は前に比べて良くなっており、これでdev.laptop.orgなどの欠かせないシステムでのダウンタイムは減ってしますだろうと期待しています。
12. Datastore (データストア): Ivanは引き続きOLPC事務所で先週開かれたデータストア・サミットの結果として出た新しいDSスペックの作業をしています。数週間後にはコミュニティによって審査できる物が出来上がると計画しています。その間Marco Gritti、Tomeu Vizoso、Eban Eliasonは2週間目もUpdate.2を可能性として目指しているいくつかのSugarユーザ経験デザイン変更をケンブリッジMAでしました。近いうちそれに付いてもっとお伝えします。
13. Security (セキュリティ): NortelのMarcus LeechはRainbowのセキュリティ・メカニズムの'isolation'シェルで作業しています。彼は欠かせないテストとパッチを提供してました。今はRainbowファイルシステム検証ツールを開発中で、Rainbow開発に結構手伝ってもらったおかげで開発ペースが急激に早くなりました。
Michael StoneはTower Researchから尋ねてきたBlake Setlowと一緒に働き、nss-rainbowモジュールの書き直しをしました。彼らは共に/etc/passwdの修正をするときにRainbowが必要だったのを取り除きました。インターフェースとデバッグのやり方が理解できたので、Michaelの予想では/etc/groupの作業は問題無しに進むと考えています。彼はUpdate.2サイクル初期にこれらの改良を入れたRainbowがリリースできると期待しています。
さらにMichaelは下記の古くなったドキュメンテーションの書き直しをしました。
- Taste the Rainbow
- http://dev.laptop.org/git/users/mstone/security
- http://dev.laptop.org/git/users/mstone/horizon
最後に彼はネットワークアクセスのコントロールと監視をするSELinux、NetLabel、sys_disablenetwork()パッチなども含めたいくつかのメカニズムの研究をしました。近いうち実験も始めます。
14. Licensing (ライセンス): Jon Phillips、Rebecca Rojer、そして、Creative Commonsから来たチームは“Sharing Creative Works” ( http://wiki.creativecommons.org/Sharing_Creative_Works をご覧下さい。)のイラスト・プライマーを作りました。 Jonの観察によると「OLPCの開発では、子供用のライセンスやトピックを中心とした学習に付いてたくさん習う物がありました」そうです。プライマーはCCの'custom licensing activity'に取り入れられ、それで子供用ライセンスの免責事項、コンセプトを説明するコミック、そしてライセンス選択表などができます。(詳しくは [Creative Commons]] をご覧下さい。)
15. Activities (アクティビティ): Arjan SarwalはTurtle Artへのセンサー組み込みを終了しました。“Turtle Art with sensors”と名乗る一時的フォークも作り、これはsensor blockが入っている新パレットも含まれています。今週に Activities ページでダウンロード出きるようのなります。
さらにArjanはBoston "Fab Lab"の高校生達とMeasureアクティビティを使った実験をしました。子供たちはセンサー・コンセプトの紹介を受け習った物を良く拾い上げてくれました。彼らは別々のグループに別れ次のプロジェクトをしました: (A) タッチセンサー・スイッチを使いドアから出入りする人数を数えTurtle Artにバーグラフとして表示する; (B) XOラップトップに接続した温度センサーを使い点数として温度vsタイムのグラフをプロットする; (C) ハイノートが鳴った時turtleにスマイリーフェースを描かせ、ローノートが鳴ったときはサードフェースを描かせる。Edward Baafiにセッションを手伝ってもらい感謝します。
Manusheel Gupta、Marco Gritti、Tomeu VizosoはDJVUとTIFFフォーマットサポートを加えるためReadアクティビティの改良をおこないました。Readアクティビティは簡単に増長するだけで他の一般フォーマットがサポート出きるようになりました。
他にManuはspreadsheetアクティビティ実装のフレームワークとアイデアを開発しました。Jim GettysとEban Elisonからの投入を受け、GNumericコードベースを元にした実装を始めました。今週ManuはGNumericチームのJody Goldbergと実装アイデアの話し合いをします。このアクティビティに興味のある方はどうぞ連絡してください。
16. Keyboards (キーボード): Bernado InnocentiはArjunとManuにxkeyboard-config、xkbファイル、キーボード・パッケージ・メンテナンスのレッスンを教えました。Bernieの手伝いを受けArjunは三つのパッチをアップストリームへ送りました。彼らはWalter Benderと一緒にDevanagari語とアルメニア語キーボードに最終タッチを加え、ネパール語キーボードレイアウトでも結構進みました。(後の方に関してはX Window System上でSCIMの代わりにComposeが使えるかを研究しています。) さらにWalterはクメール語とフランス語キーボードのレイアウトの概略を書きました (詳しくは OLPC Keyboard layouts#OLPC keyboard layouts をご覧下さい。)
17. Localisation (ローカライズ): Dr. Habib KhanのイスラマバードからのレポートではSalman MinhasとWaqas Toorのダリ語ローカライズは順調に進んでいるそうです。ダリ語サポートはXO core、XO bundle、Update.1で完成しており、Etoysとパッケージはまだ残っています。Pootleのstringsは100%ダリ語へ翻訳されました。パシュトウ語は88%完成され、XO core、Update.1、パッケージは完成済みで、EtoysとXO bundle stringsが次の目標です。パシュトウ語のストリング・コミットの防ぎとなるPootleバグがあるにも関わらずSalmanとWaqasはアフガン・ボランティア達と共に作業を行い、近いうちにローカライズが完成出きるよう願っています。
XOラップトップ・ユーザマニュアルのダリ語とパシュトウ語翻訳はアフガン・ボランティアOsmanとSohailにより完成されました。彼らが捧げた努力と献身にとても感謝しています。来週OLPCパキスタン・チームはイスラマバードにあるアフガン・ローカル・スクールで先生達とのトライアルを行う予定です。フィードバックは彼らのマニュアル完成に大変訳立つでしょう。
18. Accessibility (アクセシビリティ): トロント大学のJutta Treviranusと'International Centre for Disability Resources on the Internet'(ICDRI)の専務理事と'government services accessibility expert for the United Nations Global Alliance for Inclusive ICTs'をしているCynthia WaddelはOLPCをアクセシブルにする活動に参加したいと申し出ました。Juttaはこの数ヶ月の間に関係者の会議を開いてみるそうです。同時にRob TaylorとCodethinkはAT-SPIをD-Busに移動する調査に付いてJim Gettysと連絡をとりました ( http://live.gnome.org/GAP/AtSpiDbusInvestigation をご覧下さい)。
19. Library (ライブラリー): SJ Kleinはリポジトリとバンドル使用ケースのレビューをしました。トピックなどは改善したトラッキングに必要なメタデータとバンドル共有、そして、インドとネパールからの特定の実用ケース(Bryan Berryがそこにいました)です。Lauren Klein、Martin Langhoff、Moodle、Joshua Marks、Curriki達はローカルネットワークとウェブに一体どうやって子供たちと先生達が内容をアップロードするべきに付いて話し合いました。つい最近Currikiは教育者のためにカスタマイズされたOLPCポータルの実現を可能にするグループ機能を追加しました(開発中)。彼らはインドでオフライン状態でも使える80%ローカライズされたヒンディー語バージョンを用意しました。
メタデータに関してバンドルは下記を取り入れるよう進められました:autho、licence、URL. 新しい .infoファイルフォーマットが提案され議論の対象になっています。Mako HillとDennis Gilmoreはソース情報にどうやってリンクするかの定義とバンドル貢献者の識別方法の手伝いをしました ( Bundle metadata をご覧下さい)。
今週に開発やテストされているコレクションは下記のとおりです: モンゴル・ストーリーと高解像度イメージを含めたICDLからアップデートされたブックセット;"Where There is No Doctor"のPDFバージョン;三言語バージョン"Holocaust Encyclopedia";AJ van der VoortとEFK foundationのflash mathと言語マテリアル;Marcus Luceroが管理するInternet Archiveからの圧縮高解像度PDF。
20. Game Jams (Gameジャム): Rut JesusともしかしてOLPC Nederlandsのメンバーは150人にもなるディベロッパー達と共に来週の週末にコペンハーゲンで開かれるNordic Game Jamに参加する予定です。
21. Health (ヘルス): Adam HoltはArjun SarwalのOLPCとヘルスを中心としたボランティア・グループ組織で手伝いました (Health をご覧下さい)。彼らは共に活動を前に進めるためのリーダーシップ/調整モデルを開発しました。この頃Health collectionへの感心は急に深くなっており、Arjan、David Greisen、Erica Frank、Anna Bershteyn、Mika Matsuzaki、Ian Daniher、Seth Woodworthなど皆関連したプロジェクトで活動しています。このトピックに関連した議論はLibrary mailing listで続けられています。
