3. 현미경: 지난 주에 Robert Shapiro 교수가 Mary Lou Jepsen를 방문하여 매년 6백만명 이상의 희생자를 내는 HIV/AIDs, TB, 말라리아 진단을 위한 광학 현미경을 논의하였습니다. 놀랍게도 저배율 확대 만으로도 진단에 충분하였습니다. Barrett Comiskey도 돕고 있습니다.
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!!

3. Microscope: Professor Robert Shapiro visited Mary Lou Jepsen at OLPC last week to discuss more issues of optimal microscope design to allow the XO to provide diagnosis of HIV/AIDs, TB, and malaria, which kill more than six-million people every year, worldwide. Low-cost detection of these diseases could save many lives. Surprisingly, the key for detection is not high magnification; low magnification of a large image area and a dye coupled with violet-colored LEDs for illumination can be combined with image processing is sufficient. Professor Shapiro showed a prototype microscope to Mary Lou and discussed the basic requirements. Barrett Comiskey (whose has been designing a periscope) is also working on a low-cost microscope for the XO.

4. Testing: Translation of Sugar and the various core activities has begun in earnest. Alex Latham and Rafael Ortiz worked this week with John Palmieri to produce a build that properly supports multiple languages. (Spanish had been broken for the last few builds due to some translation problems.) Alex has plans for testing all of our international keyboard mappings.


There is now a link from the sidebar on the OLPC Wiki home page to “[[Test_issues|Test]]”, where you can get information on the latest build before you load it, test configuration notes, and review our current set of test plans. If you would like to help with our testing, there are lots of bug fixes that need verification and lots of test plans to get through.

; Dorchester : Walter Bender는 Lilla G. Fredrick 파일럿 중학교를 짧게 방문하였는데, 이 학교는 메사추세츠 주가 자금을 지원한 1:1 컴퓨팅 프로그램을 수행하는 세 학교들 중 하나입니다. 아직 XO를 이용하고 있지는 않지만, 교장인 Debra Socia는 이미 우리가 기대하는 모든 것들을 관찰하였습니다: 교사와 학생들의 참여 증가, 학부모와 공동체의 참여 증가, 학습을 둘러싼 높은 수준의 상호작용, 더 많은 글쓰기 등.


5. 스케줄: 트라이얼-3에도 약간의 버그가 남아 있습니다. 월요일에 코드 프리즈를 하고자 하니, 많은 협조 바랍니다.
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.

6. Suspend/resume problem resolution: This week the team working on the suspend/resume problems (including among others, Chris Ball, Mitch Bradley, Javier Cardona, Jordan Crouse, Richard Smith, John Watlington, and Gary Chiang) found the root cause of our “crashes upon resume” bug (the infamous bug #1835). The hardware was not allowing enough time after powering up the system clocks before bringing the Southbridge out of reset. This requires a minor hardware change to correct. A dozen machines in Cambridge have been modified, and are being used in the search for remaining suspend/resume problems. One of Chris Ball's tests passed 25,000 successful resumes in Open Firmware with the fix. Testing now shifts to wireless suspend/resume again (#1752).

7. 액티비티와 인프라스트럭처: 슈가, 텔레파시, 프레즌스 서비스, 저널과 데이터 스토어, 그리고 많은 시스템 컴포넌트들이 검수되었습니다.
<div id="news 3"/>
* 마임 타입 이노베이션을 제거하고, 적시에 적절한 액티비티들을 깨울 수 있게 되었습니다.
; UL : Quanta와 OLPC는 지난 주에 UL Taiwan에서 만나, 노트북 품질 검사 방법을 논의했습니다. B3 노트북은 열, 전기-자기 간섭, 라디오 주파수 노이즈 (와이파이로부터) 등을 테스트합니다. 우리는 40C, 45C그리고 50C 환경 속에서 최고 작동 가능 온도를 측정할 것입니다.
* 비트프로스트 시큐리티 인프라스터럭처는 디폴트로 꺼진 상태로 빌드에 통합되어, 이제 보다 쉽고 빠르게 액티비티들을 검사할 수 있게 되었습니다.
* Simon Schamijer는 브라우저의 숨김/보임 트레이 버튼과 소스보기 기능을 추가했습니다.
* 그는 또한 ogg 파일을 연주하는데 Csound를 이용하는 Memorize Game의 사운드를 동작하게 만들었습니다.
* Ranier Herres는 계산기 기능을 대폭 개선하였습니다.
* 이토이 개선이 진행 중입니다.
* Gnash이 버전 0.8.1로 갱신되었지만, 아직 넘어야할 특허 문제가 많이 남았습니다.
* Measure 는 이제 다른 오디오 어플리케이션과 마찰없이 잘 작동합니다.
*탐탐은 세 구성요소 (TamTamJam, TamTamSynthlab and TamTamEdit)로 나뉘어 열심히 유저 인터페이스를 작성하고 있습니다.
*Mark Maurer은 쓰기 액티비티의 버그를 수정하였습니다.
* 읽기 액티비티는 이제 줌과 클립보드 복사를 지원합니다.

7. Activities and infrastructure: Many fixes for Sugar, telepathy, the presence service, the Journal and datastore, and various system components were checked in during the week:
* Mime-type invocation was cleaned up in order to invoke the proper activities at the right time;
* The security infrastructure for Bitfrost is now in the builds (turned off by default) to enable easier/faster testing of activity adherence to the security model;
* Simon Schamijer added a hide/show tray button to the browser (which contains thumbnails of shared bookmarks) and a view-source feature in the browser (See [[Web_Browser]]);
* Simon also got sound working in the Memorize Game, which uses Csound to play ogg files;
* Ranier Herres completed a much improved version of the calculator, including plotting of functions;
* Improvement on Etoys continues: Bert Freudenberg has been keeping up changes in Sugar and the datastore; Kathleen Harness, Kim Rose and Yoshiki Ohshima worked on quick-help contents; Takashi Yamamiya adjusted the color picker and fonts to the XO display; Ted Kaehler is fixing the painting system; and Scott Wallace fixed various issues around fonts and scriptors.
* Gnash has been updated to Version 0.8.1; it is much improved, although patent concerns still prevent us from shipping the ffmpeg library used by many common codecs (the Adobe Flash player has also been tested extensively);
* Measure can now be safely used with other audio applications, thanks in part to an audio-driver cleanup that Andres Salomon has completed (the driver allows for independent control of the bias voltage and AC/DC coupling); Arjun Sarwal and Eben Eliason have modified the user interface to use a graphical representation of functions to encourage children to “see what this button does.”
* The TamTam team, led by Jean Piché, has been busy: TamTam has been split into three activities—TamTamJam, TamTamSynthlab and TamTamEdit—each with a massively reworked user interface;
* Mark Maurer fixed bugs in the Write Activity, most notably some synchronization bugs that manifest themselves during collaborative writing sessions; Marc Oude Kotte fixed some bugs in libabiword; and
* The Read Activity now support zoom and copy to the clipboard.

8. Keyboards: Sarmad Hussain, Tariq Badsha, Babar Haq, Salman Minhas, Naveed Ikram, and Sufyan Kakakhel have been advising Walter Bender on the design of an Urdu keyboard for Pakistan. Enkhmunkh Zurgaanjin has done the same for Mongolian.
3. 타이완 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.

; 그린: Mary Lou Jepsen은 모바일 폰의 바젤 협약 테이크-백 프로토콜 (''take-back protocol'') 저자인 John Bullock을 만나, 노트북과 관련된 환경 문제를 논의하였습니다. 바젤 협약은 1987년 시작되었으며, 재활용과 되가져오기 프로그램을 통해 유독성 물질의 배출을 줄이려는 세계적 활동입니다.
9. X Window System: Ethiopian support is improving; Bernardo Innocenti filed some bug reports to upstream projects and built packages for the builds. We also have user-oriented installation instructions for testing.


On the Xorg front, Bernie started to look at a hard-crash bug in amd_drv, triggered when the Browse Activity renders a complex iGoogle 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.


Bernie also make a lucky discovery: setting LANG=C take 5 seconds off the boot time, and possibly saves some memory too! We can set the proper locale later in the boot process: just before starting Sugar.


Stefano Fedrigo has backported promising EXA performance patches to Version 1.4. So far they resulted in a crashing server, but there is hope: while this server wont make Trial-3, it may be ready for our first deployment system.

; 슈가: 지난 두 주간 슈가 사용자 인터페이스와 기반 시스템에 상당한 진전이 있었습니다. 특히, 협동 메커니즘에 관심이 집중되었습니다.
* Marc Maurer는 아비워드 기반의 라이트 액티비티를 프레즌스 서비스와 튜브즈 API에 연동하여, 네트워크 상의 다른 사람들을 찾을 수 있도록 하였습니다.그는 C/C++로 이를 시도한 최초의 사람이며, 우리는 관심있게 지켜보고 있습니다.
* 콜레브라 팀은 프레즌스 서비스의 많은 부분을 교정하였습니다.
* 콜래브라 팀은 사용자들 상호 간에 직접 대화하기를 원하는 활동들이 그것을 프레즌스 서비스로부터 쉽게 진행할 수 있도록 해주는 스트림 API를 작성하고 있습니다.
* Marco Gritti 와 Tomeu Vizoso는 새로운 웹 액티비티 특성들을 만들고 있습니다.
* Marco는 또한 xdg 마임 시스템을 슈가 속으로 연동하고 있습니다.
* Tomeu 는 Ben Sadder과 더불어저널에 팔요한 데이터 저장의 새로운 특성들을 만들고 있습니다.
* Chris Ball은 슈가를 위한 틴더박스를 설정하고 있는데, 이를 통해, 우리의 액티비지와 슈가 개발자들이 하나의 슈가 빌드가 성공할 지 여부를 시험해보지 핞고도 판단할 수 있게 됩니다.
* Chris는 또한 우리의 이북 모드 "프립" 커널 이벤트를 인풋 레이어에 노툴시키는 커널 패치를 만들었습니다.


Jim Gettys attended part of the X developer's summit (XDS), where he discussed how to best secure the X Window System with Eamon Walsh's XACE extension. This is nearing completion, but will not be ready until early next year. He also investigated solutions of how to improve drag and drop onto the Sugar frame; there are several possibilities we will
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 focus has been on the mechanisms for collaboration:
follow up on.
* 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.
* 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.
* 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.
* 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.
* Tomeu has also been working with Ben Sadder to implement new features in the data store that are needed by the Journal.
* 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.
* 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.


In the serendipity department, one of the talks at the XDS included
information about a useful USB to VGA product on the market; there have been many requests for this capability for better use with projectors than our current network-based solutions, and this may be it.

; Etoys : Bert Freudenberg 는 Etoys에서 dbus 지원을 계속하고 있습니다;파이선으로 작성된 론처 프로그램을 건너 뜀으로서, 이토이의 시동 시간이 훨씬 짧아졌습니다. 다카시 야마미야의 클립도드 작업도 지속되오 깄습니다: 그는 이토이로부터 슈가로 오브젝트를 복사하기 위한 X 프로토콜을 실험하고 있는데, 슈가에서 그것들은 다른 활동들, 가령 저널로부터 접근할 수 있습니다. 요시키 오시마는 팡고와의 통합을 진행하고 있는데, 이토이의 더 많고 나아진 언어 지원을 제공할 것입니다. Scott Wallace는 익스프레션 타일을 실험하고 있으며, Ted Kaehler는 물리학 시뮬레이션의 이토이 표본을 만들고 있습니다.
10. Kernel: Andres Salomon committed audio-driver fixes (the capture device should now be in a sane state when the device is opened/closed, HPF and V_REF are no longer coupled, etc.), enabled the es1371 module for VMware users, and included a missing battery feature (accumulated_current) into the stable tree. The other major effort this week was in support of fine-tuning power usage; Andres has started working on tests using the battery's ACR registers to get better measurements of power savings that result from various tweaks.
; evitando el lanzador (''launcher'') escrito en Python, el tiempo de arranque de Etoys será mucho menor. El trabajo de Takashi Yamamiya en el portapapeles prosigue: está experimentando con el protocolo X para copiar objetos desde Etoys a Sugar, donde pueden ser usados por otras actividades, incluyendo el Diario. Yoshiki Ohshima está trabajando en la integración con Pango, lo cual permitirá un mejor manejo de idiomas a Etoys. Scott Wallace experimentó con 'tejas' (''tiles'') de expresiones y Ted Kaehler sigue trabajando sobre una demostración de física en Etoys.

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.


11. Updates: Scott Ananian pushed manifests, upgrades, and OS signing into the build process and is working on updating our activation process with “real” cryptography. Scott also documented Eben Eliason and Rebecca Allen's startup UI design (See [[Startup_Sequence]]) and split it into a number of manageable implementation steps.


12. Firmware: Mitch Bradley continuing work this on firmware security, and on better tools for checking NAND FLASH integrity. Two bugs consumed 98% of Richard Smith's time this week:
<div id="news 7"/>
(1) the resume problem as reported above, which was resolved; and
; 스쿨 서버: Dave Woodhouse는 John Watlington과 더불어, 스쿨 서버와 IPv6 구성을 진행하였습니다. Holger Levsen는 i386, PowerPC를 위한 페도라 코어 6과 7 소스를 운반하는 로컬 미러를 구축하였습니다.
(2) a mysterious “turn off” problem—the core of the problem is that the timing used by the embedded controller (EC) to assert the PWR_BUT# signal is based a loop counter rather than a timer; Richard is looking into fixing this.


13. 월드 디지털 라이버러리: John van Oudenaren and Michelle Rago의 지휘 하에 10월 15일 유네스코 총회에서의 시연을 위한 준비를 7개국어 라이버러리 인터페이스를 마감하고 있습니다. 이 시연은 세계 각지로부터 60 기가바이트의 자료를 끌어오는데, 인도 역사가 하이라이트 입니다. 그들은 이 시연을 세 기기에서 보여줍니다: XO, 클라스메이트, 그리고 아이폰입니다.
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]].

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.

* 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.


17. 이메일 클라이언트: Mark Doffman은 Tinymail을 위한 파이썬 바인딩을 작업하고 있는데, XO를 위한 프러덕션 클라이언트를 마무리하기 위한 실질적인 "슈거라이제이션"에서 도움을 받고 있습니다.

Laptop News 2007-09-15

1. 인터넷과 위성 통신 분야의 30년 경력 베테랑 Thomas Jacobson이 초저비용 업데이트와 컨텐트 배포를 위한 위성 활용에 관해 이틀 간에 걸쳐 OLPC와 논의하였습니다. (See http://www.tcjnet.com/xosat.html)

1. Thomas Jacobson, a network consultant with over 30 years of experience with Internet and satellite communications, spent two days at OLPC discussing how we can best take advantage of satellites for very low-cost bit distribution (updates and content). He gave a talk on Thursday (See http://www.tcjnet.com/xosat.html).

2. Nortel CTO John Roese의 XO에 관한 블로그 글: See http://blogs.nortel.com/ctoblog/2007/09/12/one-laptop-per-child-where-in-the-world-is-that-cool-green-and-white-laptop).

2. Nortel CTO John Roese has been blogging about the XO (See http://blogs.nortel.com/ctoblog/2007/09/12/one-laptop-per-child-where-in-the-world-is-that-cool-green-and-white-laptop).

3. 현미경: 지난 주에 Robert Shapiro 교수가 Mary Lou Jepsen를 방문하여 매년 6백만명 이상의 희생자를 내는 HIV/AIDs, TB, 말라리아 진단을 위한 광학 현미경을 논의하였습니다. 놀랍게도 저배율 확대 만으로도 진단에 충분하였습니다. Barrett Comiskey도 돕고 있습니다.

3. Microscope: Professor Robert Shapiro visited Mary Lou Jepsen at OLPC last week to discuss more issues of optimal microscope design to allow the XO to provide diagnosis of HIV/AIDs, TB, and malaria, which kill more than six-million people every year, worldwide. Low-cost detection of these diseases could save many lives. Surprisingly, the key for detection is not high magnification; low magnification of a large image area and a dye coupled with violet-colored LEDs for illumination can be combined with image processing is sufficient. Professor Shapiro showed a prototype microscope to Mary Lou and discussed the basic requirements. Barrett Comiskey (whose has been designing a periscope) is also working on a low-cost microscope for the XO.

4. 테스팅: 슈가와 다양한 핵심 액티비티들의 번역이 열심히 진행 중입니다. 다국어 지원을 위해 Alex Latham and Rafael Ortiz는 John Palmieri와 더불어 작업하고 있습니다. Alex는 모든 국제 키보드 매핑을 테스팅하고 있습니다.

4. Testing: Translation of Sugar and the various core activities has begun in earnest. Alex Latham and Rafael Ortiz worked this week with John Palmieri to produce a build that properly supports multiple languages. (Spanish had been broken for the last few builds due to some translation problems.) Alex has plans for testing all of our international keyboard mappings.

There is now a link from the sidebar on the OLPC Wiki home page to “Test”, where you can get information on the latest build before you load it, test configuration notes, and review our current set of test plans. If you would like to help with our testing, there are lots of bug fixes that need verification and lots of test plans to get through.

5. 스케줄: 트라이얼-3에도 약간의 버그가 남아 있습니다. 월요일에 코드 프리즈를 하고자 하니, 많은 협조 바랍니다.

5. Schedule: There are still some bugs that need triage in Trial-3. We want to be at code freeze on Monday, so please do the best you can to get your bug fixes checked in this weekend. Starting Monday we want to get approval from Jim Gettys for every code change (bug fix) before committing.

6. 서스펜드/리줌 문제 해결: 특히 Chris Ball, Mitch Bradley, Javier Cardona, Jordan Crouse, Richard Smith, John Watlington, and Gary Chiang이 이 버그의 근본 원인을 찾아서 해결했습니다.

6. Suspend/resume problem resolution: This week the team working on the suspend/resume problems (including among others, Chris Ball, Mitch Bradley, Javier Cardona, Jordan Crouse, Richard Smith, John Watlington, and Gary Chiang) found the root cause of our “crashes upon resume” bug (the infamous bug #1835). The hardware was not allowing enough time after powering up the system clocks before bringing the Southbridge out of reset. This requires a minor hardware change to correct. A dozen machines in Cambridge have been modified, and are being used in the search for remaining suspend/resume problems. One of Chris Ball's tests passed 25,000 successful resumes in Open Firmware with the fix. Testing now shifts to wireless suspend/resume again (#1752).

7. 액티비티와 인프라스트럭처: 슈가, 텔레파시, 프레즌스 서비스, 저널과 데이터 스토어, 그리고 많은 시스템 컴포넌트들이 검수되었습니다.

  • 마임 타입 이노베이션을 제거하고, 적시에 적절한 액티비티들을 깨울 수 있게 되었습니다.
  • 비트프로스트 시큐리티 인프라스터럭처는 디폴트로 꺼진 상태로 빌드에 통합되어, 이제 보다 쉽고 빠르게 액티비티들을 검사할 수 있게 되었습니다.
  • Simon Schamijer는 브라우저의 숨김/보임 트레이 버튼과 소스보기 기능을 추가했습니다.
  • 그는 또한 ogg 파일을 연주하는데 Csound를 이용하는 Memorize Game의 사운드를 동작하게 만들었습니다.
  • Ranier Herres는 계산기 기능을 대폭 개선하였습니다.
  • 이토이 개선이 진행 중입니다.
  • Gnash이 버전 0.8.1로 갱신되었지만, 아직 넘어야할 특허 문제가 많이 남았습니다.
  • Measure 는 이제 다른 오디오 어플리케이션과 마찰없이 잘 작동합니다.
  • 탐탐은 세 구성요소 (TamTamJam, TamTamSynthlab and TamTamEdit)로 나뉘어 열심히 유저 인터페이스를 작성하고 있습니다.
  • Mark Maurer은 쓰기 액티비티의 버그를 수정하였습니다.
  • 읽기 액티비티는 이제 줌과 클립보드 복사를 지원합니다.

7. Activities and infrastructure: Many fixes for Sugar, telepathy, the presence service, the Journal and datastore, and various system components were checked in during the week:

  • Mime-type invocation was cleaned up in order to invoke the proper activities at the right time;
  • The security infrastructure for Bitfrost is now in the builds (turned off by default) to enable easier/faster testing of activity adherence to the security model;
  • Simon Schamijer added a hide/show tray button to the browser (which contains thumbnails of shared bookmarks) and a view-source feature in the browser (See Web_Browser);
  • Simon also got sound working in the Memorize Game, which uses Csound to play ogg files;
  • Ranier Herres completed a much improved version of the calculator, including plotting of functions;
  • Improvement on Etoys continues: Bert Freudenberg has been keeping up changes in Sugar and the datastore; Kathleen Harness, Kim Rose and Yoshiki Ohshima worked on quick-help contents; Takashi Yamamiya adjusted the color picker and fonts to the XO display; Ted Kaehler is fixing the painting system; and Scott Wallace fixed various issues around fonts and scriptors.
  • Gnash has been updated to Version 0.8.1; it is much improved, although patent concerns still prevent us from shipping the ffmpeg library used by many common codecs (the Adobe Flash player has also been tested extensively);
  • Measure can now be safely used with other audio applications, thanks in part to an audio-driver cleanup that Andres Salomon has completed (the driver allows for independent control of the bias voltage and AC/DC coupling); Arjun Sarwal and Eben Eliason have modified the user interface to use a graphical representation of functions to encourage children to “see what this button does.”
  • The TamTam team, led by Jean Piché, has been busy: TamTam has been split into three activities—TamTamJam, TamTamSynthlab and TamTamEdit—each with a massively reworked user interface;
  • Mark Maurer fixed bugs in the Write Activity, most notably some synchronization bugs that manifest themselves during collaborative writing sessions; Marc Oude Kotte fixed some bugs in libabiword; and
  • The Read Activity now support zoom and copy to the clipboard.

8. Keyboards: Sarmad Hussain, Tariq Badsha, Babar Haq, Salman Minhas, Naveed Ikram, and Sufyan Kakakhel have been advising Walter Bender on the design of an Urdu keyboard for Pakistan. Enkhmunkh Zurgaanjin has done the same for Mongolian.


9. X 윈도우 시스템: 이디오피아 지원이 개선되고 있습니다.

{{{1}}}

10. 커널: Andres Salomon은 오디오 드라이버 코드를 수정, (음성녹음 장치를 열고 닫을 때의 문제, HPF와 V_REF 수정등). 또, VMware 사용자를 위한 es1371 모둘, 배터리가 없을때의 처리기능등을 stable 소스 트리로 제출하였습니다. 기타 이번주의 주요 결과물은 다음과 같습니다. Angres가 여러가지 조작을 통해서 건전지의 ACR 값을 사용하는 기능을 테스트하기 시작하였습니다.

10. Kernel: Andres Salomon committed audio-driver fixes (the capture device should now be in a sane state when the device is opened/closed, HPF and V_REF are no longer coupled, etc.), enabled the es1371 module for VMware users, and included a missing battery feature (accumulated_current) into the stable tree. The other major effort this week was in support of fine-tuning power usage; Andres has started working on tests using the battery's ACR registers to get better measurements of power savings that result from various tweaks.


11. Updates: Scott Ananian pushed manifests, upgrades, and OS signing into the build process and is working on updating our activation process with “real” cryptography. Scott also documented Eben Eliason and Rebecca Allen's startup UI design (See Startup_Sequence) and split it into a number of manageable implementation steps.

12. Firmware: Mitch Bradley continuing work this on firmware security, and on better tools for checking NAND FLASH integrity. Two bugs consumed 98% of Richard Smith's time this week: (1) the resume problem as reported above, which was resolved; and (2) a mysterious “turn off” problem—the core of the problem is that the timing used by the embedded controller (EC) to assert the PWR_BUT# signal is based a loop counter rather than a timer; Richard is looking into fixing this.

13. 월드 디지털 라이버러리: John van Oudenaren and Michelle Rago의 지휘 하에 10월 15일 유네스코 총회에서의 시연을 위한 준비를 7개국어 라이버러리 인터페이스를 마감하고 있습니다. 이 시연은 세계 각지로부터 60 기가바이트의 자료를 끌어오는데, 인도 역사가 하이라이트 입니다. 그들은 이 시연을 세 기기에서 보여줍니다: XO, 클라스메이트, 그리고 아이폰입니다.

13. World Digital Library: The World Digital Library team, under the direction of John van Oudenaren and Michelle Rago, is finishing a working model of their visual seven-language library interface this month in preparation for a public demonstration at the UNESCO general conference October 15. The demonstration will draw on 60GB of materials from around the world, with highlights from the history of India. They will be showcasing the demo on three devices: the XO, the Classmate, and the iPhone.

14. Help wanted: ePals wants to hire a Python developer next week to finish a Sugarized activity that offers access to their PenPal services. They have a design almost completed, and expect this to be around 40 hours of work. The Library of Congress is considering up to three unpaid internships this fall with office space in their Science and Technology Sections, to identify educational and illustrative materials in the public domain and to get digital versions of them online and bundled for their own website and for OLPC collections. This is an opportunity to have unlimited access to their stacks and to get experience with modern digitization processes. Contact SJ Klein (sj at laptop dot org) for details regarding both positions.


15. 이디오피아 텍스트: Emma Shercliffe of Macmillan and Ignatz Heinz of Avallain은 이번 달에 언어 학습 도구와 아디스 팀을 위한 이디오피아 텍스트와 자료 수집 작업을 마무리하고 있습니다. Macmillan은 아프리카의 로컬 팀들과 더불어 교육부와 학교들을 돕는데 관심이 있습니다. 그들은 그 곳의 거의 절반에 가까운 지역에 지역 저자와 출판 지사들을 보유하고 있습니다.

15. Ethiopian texts: Emma Shercliffe of Macmillan and Ignatz Heinz of Avallain are finishing work on a language-learning tool this month, and a collection of Ethiopian texts and materials for the team in Addis. They will make this material available to the world. Macmillan is also interested in working with local teams across Africa to help share their experiences working with education ministries and schools; they have local authors and publishing branches in around half of the countries there.


16. 문자 인식: Kaiserslautern 의 컴퓨터 과학 교수인 Thomas Breuel은 구글을 북 스캐닝 프로젝트에서 어려운 문자 인식 문제들을 다루고 있는데, XO 터치패드에 손으로 쓴 글자를 인식하는 기능을 테스트하고 있습니다.

16. Character recongnition: Thomas Breuel, a computer science professor at Kaiserslautern who is working on some of the harder character-recognition problems for Google's book scanning project, has been testing a handwriting-recognition application with the XO touchpad.

17. 이메일 클라이언트: Mark Doffman은 Tinymail을 위한 파이썬 바인딩을 작업하고 있는데, XO를 위한 프러덕션 클라이언트를 마무리하기 위한 실질적인 "슈거라이제이션"에서 도움을 받고 있습니다.

17. Email client: Mark Doffman has been working on the Python bindings for Tinymail. He could use some help with the actual “Sugarization” to complete a production client for an XO (See http://pvanhoof.be/blog/index.php/2007/09/05/python-bindings-of-tinymail and http://mail.gnome.org/archives/tinymail-devel-list/2007-September/msg00000.html).

18. 오프라인 위키: moulin-wiki의 Renaud Gaudin은 (오픈소스 데이터 마이닝 그룹) Linterweb에서 프랑스 개발팀 및 프랑스 위키피디언들과 작업하고 있습니다. 그들은 오프라인 위키 리더를 구성하고 있습니다.
