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).
1. Arahuay, Peru: Carla Gomez Monroy has been helping the ministry of education with a school trial at the Institución Educativa Apóstol Santiago, a combination primary and secondary school in a small town in the Cordillera de la Viuda, 2600 m. above sea level.

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).
2. Taipei: Mary Lou Jepsen gave a keynote at a display manufacturing conference in Taipei where she highlighted the fact that the XO display took only six months to go from specification to full certification, ready for high-volume mass production product. This rapid development is unheard of in the display industry where 10-to-20 years is more the norm for a new display—and thus the XO was the center of much discussion at the conference. Other large display manufacturers are expressing interest in helping with Gen2 development as well as providing a second source of the Gen1 display. Of course Mary Lou explained our loyalty and strong relationship with ChiMei. The reception was quite different from 18 months ago, when getting buy-in from the display manufacturers was one of the largest challenges for OLPC.

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. OLPC는 American Express Card의 Members Project (http://www.membersproject.com) 후보로 선정되었습니다. 승자는 $1–$5백만 달러의 지원금을 받게 됩니다. OLPC는 프로젝트 번호 07229로 등재되었습니다.

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.
3. OLPC was nominated and selected as a potential beneficiary of the American Express Card's Members Project (http://www.membersproject.com). Projects are voted for through several rounds and the winners are eligible for a grant of between $1–$5 million. OLPC is listed under project number 07229.

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. XO 시험: 콴타는 A 테스트에서 B1–B4까지 다섯 단계의 개발 동안, 약 7,000 여대의 노트북 프로토타입을 온도, 전기, 기계, 지구성, 그리고 환경 실험에 투입하였습니다.

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.
4. XO testing: Quanta has put an enormous effort into testing the laptops in each of the five builds to date (A Test and B1–B4). The approximately 7000 prototypes have undergone temperature, electrical, mechanical, durability, and environmental testing:


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.
Temperature: 55C/40% relative humidity (RH) operation test, 32C/50% RH operation test, 30C/85% RH operation test, –0C operation test, 85C storage test, –40C storage test, thermal shock and profile test (60C to –20C);

Electrical: AC power, BIOS flashing, Open Firmware, power management, USB 2.0, NAND flash, Wireless LAN, camera, memory, battery, LED indicator, stress test, ESD, battery discharge, LCD module verification, line-voltage and frequency test, power-on/off test, altitude test, wave-form measurement, frequency response, speaker performance, touch-pad performance, S0 state, S3 states, driver level, frequency accuracy, oscillation allowance, negative resistance, load capacitance, DDR1, critical trace, power-rail ramp, voltage level and noise, USB 1.1, Radiation of EN 55022, EN 61000-4-4, skin/case temperature, etc.;

Mechanical environmental test: operating and non-operating vibration test, operating and non-operating shock test, package drop test, package storage test, tilt drop test, free drop test, LCD stress test, base pressure test, LCD-pressure vibration test, switch-protection test, LCD-twist test, connector-tension test, adapter-cable bending test, spill test, water test;

Durability test: hinge 65K cycles, battery 10K cycles, buttons 1M cycles, power button 700K cycles, touch-pad buttons 3M cycles, USB ports 10K cycles, DC in 20K cycles, DC-in, line-out, and mic-in 10K cycles, wireless-antenna 5K cycles, SD card 16K cycles;

Special environmental test: sand and dust test, salt-fog test, solar- radiation test, rain test;

Abusive test: free-throw test, USB and SD card reverse test, tumbling test, water-sprinkle test, hinge max-angle test, tablet-mode max-angle test, antenna max-force test.

These are torture tests. Most of these tests are harder—by far—than that required for conventional laptops Currently, XO has passed the vast majority of tests. Provisions to pass the tough ESD, salt-fog, power-on/off test, and operating shock test are under way; as are even higher free-drop tests, more stringent hinge-torque tests; as well as stronger set of testing underway at UL as we enter C-Test phase in August.

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).
6. Trial-2 software: At the beginning of the week we added the latest Marvell firmware to both the XO and the school server software images to get past “flag day” in Cambridge: builds before Build 486 (or Build 406.16) will not work with these later builds. Henceforth, as we send products out to the field, we need to know if the recipient already has XOs; any older machines will need to be upgraded so the new ones and old ones will work together. (The test group continues to keep a log of Release Notes for each build, which can be accessed at [[Test Group Release Notes]].

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:
7. Hardware management: Richard Hughes continued his work on our hardware policy manager. He is in the final stages of getting it into our builds by running it through the Fedora review process. Matthias Clasen has been helping him run through the process and has been pointing out improvements to be made. He also integrated open hardware manager (OHM) with the new X IDLETIME alarm interface. He also added support for the battery and AC adapter to the hardware abstraction layer (HAL) so that it is more easily exported to programs. Using this interface, Marco Gritti has added support to Sugar to extract the battery information from HAL.
* 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.

9. Building builds: John Palmieri continued pushing builds out the door. He has been splitting his time between trying to get Trail-2 work done and also working on a stable 406 build (the latter build includes power management and other low-level features, but not the new collaboration and Journal features). He also worked on getting QEMU (an open source machine emulator and virtualizer) and VirtualBox (a commercial virtualizer) working with our images again.


9. X 윈도우 시스템: 이디오피아 지원이 개선되고 있습니다.
The basic Vmware image conversion process outlined at in the OLPC wiki (See [[Emulating the XO/UsingVMware]]) is also working. Scott Devine has been working on VMware mesh-network emulation and the XO images are now part of Vmware’s daily regression testing.

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.
10. Sugar: Marco Gritti and Tomeu Vizoso continue to chase bugs in Sugar and the Journal as part of the Trail 2 work. Walter Bender and Eben Eliason revisited the XO color schemes; more vivid and legible color dyads will be available in the upcoming builds. Dan Williams worked on Network Manager, fixed an avahi bug, fought through numerous packaging issues as part of the Fedora Core 7 move, and also worked on some gstreamer issues around camera support.


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.
11. 업데이트: Scott Ananian은 업그레이드 사이즈 최저 한계를 알아보기 위해, bsdiff/bspatch에 기초한 recursive binary diff tool을 작성하였습니다. rsync 과 비교하여, 그리고 Dan Williams patched version of “updatinator”과 비교하여, 우리의 다양한 업그레이드 전략들은 아직 전혀 이상적인 형태가 아닙니다.

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.
12. 12. X Window System:Bernie Innocenti는 bug #1837, the “fancy color on text” bug를 다루고 있는데, 아주 애먹고 있습니다.
{{ Translated text |
12. X Window System: Bernie Innocenti spent much of the week working on bug #1837, the “fancy color on text” bug, which turned out to be pretty tough. The more he dug into it, the more he keep getting evidence pointing in opposite directions. We see similar text corruption on OLPC, F8 and Ubuntu Gutsy on the Geode LX (both 16bpp and 32bpp) and Radeon R200 (but only in 16bpp) in both with EXA and XAA. Disabling acceleration cures it. The plot thickens.


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.
Another serious bug that had been making the X server on the GX (B2 and B1) unusable in the development builds was found through work of Jordan Crouse and Adam Jackson late Friday afternoon.


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
13. Kernel: Andres Salomon worked on getting code upstream this week. The Geode support in master is mostly in Andrew Morton's tree; some is trickling into Linus's tree as well. Andres also did the standard merge dance (nothing exciting there, though we should be approaching a final 2.6.22 soon). Marcelo Tosatti spent time merging his USB changes to master.

In the serendipity department, one of the talks at the XDS included
Marcelo and Chris Ball looked into some suspend/resume failures. We can reliably suspend and resume wireless so long as the wireless module remains connected to the USB; Marcelo and Cozybit continue to investigate issues suspending and resuming with the wireless disconnected entirely.
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.

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.
The “pop” that we receive from the amplifier is barely audible on the B4 machines, but we will continue to investigate it—if the pop is caused by a hardware bug, now is the time to fix it.

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.

The microphone LED was turning on regardless of whether we were using the audio device for playback or recording. Chris came up with logic to keep it turned off when we aren't recording, implemented it, and will send his patch to Jaya Kumar for review.


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.
Scott imported glibc into git and (after some fighting) got it to build, so he is setup to write the glibc RDNSS-over-RA patches.


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.

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.
Dan Margo completed the scripts that will let us build OLPC-specific RPM configuration packages. These packages follow a fairly complex install-and-update policy that: (A) organizes OLPC-specific configurations into a central directory, etc.olpc; and (B) respects user's configuration changes, while clobbering RPM defaults. These scripts are in want of more debugging on large, serious use cases, but are concept-complete.


Next week we plan to start building Fedora Core 7 livecd build scripts from a clean slate (and merge the work Holger has done based on Fedora 6) Once that is straightened out, we can start determining and then exporting the XS-specific configurations.


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.
Scott also fought the QEMU/KVM (kernel-based virtual machine) fight and got XO and (sort of) XSX images built and working under emulation. The ground is laid for Dan and Scott to create XSX builds based on Fedora Core 7 images next week using Dan's rpm-configuration code.

15. Security: Mitch and Ivan Krstić hashed out firmware security issues around activation, firmware updates, and developer keys. Ivan, Mitch, and Scott defined three code-paths: (1) the chain from booting a signed kernel though invoking activation or pivoting to one of two base file-systems (upgrade or backup); (2) the anti-theft server, anti-theft client, and “invoke-upgrade-now” interactions; and (3) the fetch-upgrade hand-off to the security kernel, which validates the upgrade and tweaks some bits to signal the boot code (closing the circle). Implementation has begun: Ivan has built a skeleton antitheft server and client, and Scott has an initrd that takes control immediately after open firmware boots our (signed) kernel.

To help with the ongoing debugging efforts of Trac Bug #1752 Richard created a test version of the EC code that asserts the WLAN wakeup pin before issuing the SCI to the host. This allows the WLAN to have its USB bus up and running prior to the host. Experiments with WLAN firmware that does not detach from the USB bus works with suspend/resume. The EC test firmware was a possible workaround but Chris found that it still had issues.

David Woodhouse and Richard worked on making the PCB temp sensor work and verify that the resistor divider is set correctly. However, they found that the EC code is not working correctly. The voltage A/D readings do not appear to be updating. With a bit of Forth code under OFW to read the A/D directly and then they looked at the range of the sensor.

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).
17. Content jams: The Commonwealth of Learning (COL) is working actively on open content for educators and students, especially those in regions newly introduced to computers. They are interested in starting a Summer of Content project along with OLPC, supporting existing open content efforts and focusing on short-term goals that will lead to literacy and more content creation. They are starting work on a Spanish Wikieducator, and planning content-creation workshops in each of the 53 Commonwealth states. Mel Chua met with Wayne Mackintosh of COL and worked out some initial details. Summer of Content would provide visibility to open content projects that need help and a unified way for interested students and young teachers to intern for these projects, focusing on potential interns in the Southern Hemisphere and running two summers a year, starting at the end of this calendar year.

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.

18. Off-line wiki: Renaud Gaudin of moulin-wiki is working with the French development team at Linterweb (an open-source data-mining group) and the French Wikipedians. Together, they are building an off-line wiki reader.
