Laptop News 2007-09-01
1. 스케줄/테스팅: 이번 주는 "기능 동결"의 주였으며, 주말 무렵 Trial-3 소프트웨어 릴리즈의 최종 버전에 근접했습니다. 수많은 기능들을 점검하고, 버그를 수정하였습니다. 다음 주에는 안정성에 주력할 것이며, 정지 및 재개와 관련된 버그 수정에 큰 진전이 있었습니다. Trial-3에 추가할 기능은 없으며, 더 원한다면 Jim Gettys와 Kim Quirk에 문의하십시오.
1. Schedules/testing: This week was “feature freeze” and by the end of the week we were very close to finalizing the feature set for the Trial-3 software release. Since there were a lot of new features getting checked in, we saw numerous builds and wrote up and fixed many, many blocking and regression bugs. Over the next week we will be focused on stability, through bug fixing and testing. There was some good progress on some of the biggest (and loudest) bugs related to suspend and resume, which is great to see. No more features for Trial-3. If you think there is an exception to this rule, please contact Jim Gettys and Kim Quirk.
2. 슈가: Collabora 팀은 다가오는 소프트웨어 릴리즈 전에 최종 아이템들을 손보고 있습니다. 그 중에는 가변적 액티비티 속성 (이름, 태그, 컬러 등), 초대 지원, 새로운 튜브 스펙으로 많은 액티비티들을 포팅하고, 베이스 시스템 요소들을 정리한 것 등입니다. Morgan Collett는 Connect and Chat 액티비티에 새로운 인터페이스를 입혔습니다.
스쿨서버를 선택하지 않으면, MIT 협동 센터의 기존 서버가 개별 개발자들이 공유할 공간을 제공할 것입니다.
Jean Piché 팀의 탐탐 새 버전이 새로운 빌드에 포함되었습니다.
(Amharic과 같은 언어를 지원할 수 있는) Pango와 Cairo가 최종 버전으로 갱신되었습니다.
Chris Ball은 Pippy에 저널 통합, Nathanaël Lécaudé과 TamTam 팀으로부터의 사운드 지원, Madeleine Ball, Mel Chua, 그리고 Rafael Ortiz의 새로운 샘플들을 추가하였습니다.
Simon Schamijer은 새로운 튜브 API를 위한 Memorize 액티비티를 업데이트하였습니다.
시몬은 또한 웹 브라우저를 다루고 있습니다 (웹브라우저에서 시각적 디자인을 살펴보세요). 그는 공유가능한 링크 트래이를 추가했으며, 공유 브라우저 세션에서의 버그를 수정하였습니다.
Marc Maurer는 Abiword (Write Activity) 협업 백엔드를 작업하였습니다. 그는 쓰기를 위한 새로운 포맷 툴바를 추가했으며, 일부 추가적인 스타일 옵션들을 더 했습니다 (머릿말, 번호메기기, 불릿 등). 또한 저널에서 직접 쓰기에 이미지를 추가할 수 있는 기능을 더 했습니다.
2. Sugar: The Collabora team continued to work on final items before the upcoming software release. This included adding support for mutable activity properties (name, tags, colors, etc), invitation support, porting of many of the activities over to the new tubes specification and cleaning up a lot of the base system elements. Morgan Collett updated the Connect and Chat activities to the new interfaces.
If no school server is chosen, a presence server in the MIT collocation center is being used to enable individual developers to share.
A new version of TamTam from Jean Piché's team is included in the new builds.
Pango (to enable support for languages like Amharic) and Cairo were updated to their latest versions.
Chris Ball updated Pippy to add journal integration, sound support from Nathanaël Lécaudé and the TamTam team, and new examples from Madeleine Ball, Mel Chua, and Rafael Ortiz.
Simon Schamijer updated the Memorize activity for the new tubes API.
Simon also has been working on a the web browser (See the new visual design at Web_Browser). He added a sharable link tray and fixed bugs in the shared browser session.
Marc Maurer worked on the Abiword (Write Activity) collaboration backend. He also added a new format toolbar to Write and added some additional style options (headings, numbering, bullets, etc.) He also added the ability to insert images into Write directly from the Journal.
3. 업그레이드와 멀티부트: Scott Ananian는 XO에 페도라 슈가와 더불어 데비안 리눅스를 설치했는데, 새로운 업그레이드 메커니즘을 증명하기 위해서 입니다. 업그레이드 시, 옛 버전을 그대로 두고 새 버전을 설치해 볼 수 있습니다.
3. Upgrades and multi-boot: Scott Ananian installed Debian Linux alongside Fedora Sugar on an XO as a demonstration of the new upgrade mechanism, which allows you to keep the old version around and boot into if the upgrade goes awry; and the P_SF_RUN Bitfrost security mechanism, which allows a child to poke around the root filesystem and muck with things, while still being able to revert to the “pristine” OS image if things go wrong (See preliminary instructions at Installing_Debian_as_an_upgrade. This will get much easier next week as the rest of the upgrade infrastructure is rolled out: you will be able to just subscribe to the “debian” stream to get Debian installed (for example). There will be “stable” and “devel” streams for Sugar releases—the real point of this work.
4. X 윈도우 시스템: Bernie와 Walter Bender는 대량 생산을 위한 키보드 레이아웃을 결정했습니다. Image:Keyboard_english.png를 보세요.
4. X Window System: Bernardo Innocenti merged more xkb changes for our existing keymaps, defined a few missing keysyms and updated the olpc patch in response to Sergey Udaltsov 's reviews. He is currently testing new RPMs. A new patch submission is due soon.
Bernie and Walter Bender have also been finalizing the keyboard layouts for mass production (By way of example, see Image:Keyboard_english.png).
5. Embedded controller: Richard worked on the “battery-always-charging” bug. It does not appear to be just an EC problem as Open Firmware shows the correct status but the kernel does not. They both use the same EC commands. It is still unclear what is wrong.
6. The Wireless Bug (Trac #1835): Richard is also working on this bug. The more he gets into it, the more it smells like hardware. On a resume, after some number of cycles, the machine will hang. It is likely that we are not getting good data from the reset-vector fetch. The next step is to decode the LPC (low pin-count) bus and see what data is coming back in the fail case.
Javier Cardona and Chris Ball also continued work on the wireless-resume bug. Javier added debugging code that is providing useful information on each crash, and is continuing to try to iron out the bugs as we find them.
Richard and Chris found a bug where the CPU occasionally on resume appears to be stalling instead of executing instructions. Since this happens during our extreme-traffic wireless-resume testing, the problem could be as simple as us not giving the power rails enough time to quiesce. Richard is working on it. | display = small }}
7. 스쿨서버: 스쿨 서버 소프트웨어는 계속 개선되고 있습니다; 새로운 릴리즈는 여러가지 버그를 수정하였으며, 다음 주에는 노트북 등록 서비스가 시작될 것으로 보입니다. 캠브리지와 같은 밀집지역에서 서버를 개발하는데 도움이 되도록, John Watlington은 메쉬 블라인딩 테이블을 테스트 및 문서화하였습니다 (See 메쉬 디버그). 새로운 스쿨서버 몇몇이 온라인에 연결되었는데, 하나는 인도에서, 하나는 컨텐트 개발을 위해, 몇몇은 캠브리지에서 테스트를 위해서 입니다.
7. School server: The school server software continues to improve; a new release with several bug fixes and the laptop registration service is expected by the beginning of next week. To aid in server development in crowded work areas (such as Cambridge), John Watlington tested and documented the mesh blinding tables (See Mesh_Debug). Several new school servers came online this week: one for a trial in India, one for content development, and several for testing in Cambridge.
8. Kernel: This week Andres Salomon worked on vserver patches and fixing sound bugs. The screeching-upon-resume bug has been fixed, along with a number of other sound bugs. The patches been pushed upstream. A few bugs still remain, but no known major ones.
Marcelo Tosatti added code to our kernels that makes it possible to trace how long suspend/resume cycles take. This should allow us to pinpoint where we spend a lot of our time. Currently, the largest consumer of time turns out to be writing to the serial console during resume.
9. Firmware: Mitch Bradley Released Q2C26 firmware with OS security and activation support, some bug fixes, improved NAND FLASH bad-block management, and created a kit for creating signed OS images and leases. Lilian Walter put into place the code to solicit stateless DHCPv6 information. She is finishing up IPv6 fragmentation and reassembly.
10. Wireless: Michail borrowed an Anritsu Network analyzer and did some antenna performance measurements on the C- and B- Build laptops. He is happy to report that the C Build units are the first ones with completely functioning antennas. Quanta has implemented grounding of the antenna cable's shield in the C-Build machine and that seems to have made the right antenna perform properly. Michail’s only comment is that the insulation on the left antenna's wire is being stripped too short: the braid deforms from the mechanical stress imposed on it during the antenna's rotation. The insulation has to be left intact all the way to the grounding sticker as it the case with the right antenna.
Note: the C-Build laptops have metalization all around the plastic parts. Because of that, when the antennas are closed, the plastic below them acts as a ground plane and diminishes the antenna's performance completely compared to the previous builds. The antennas work much better when in the up position on the C-Build laptops.
11. Build 542.3: John (J5) Palmieri reports that a new spin of the stable build fixes a bug in Sugar that had prevented the installation of translation files; it also fixes a Journal bug for the Spanish locale.
http://olpc.download.redhat.com/olpc/streams/development/build542.3/
When installing this image, it should be named 'os5423.img' (along with the corresponding 'os5423.crc'). The FAT file system would otherwise be unhappy with the double dots in the names and the auto-reinstallation script would thus refuse to install them.
12. OLPC Philippines has registered a name. It is named as OLPCPH. OLPC_Philippines
