But most of the ones who actually use such a system, even when they grow up, end up using the files-in-folders system in a very inefficient way (from personal, direct observation of people who are not IT professionals). Secondly, from a utility perspective... Have you ever tried to move a file out of the Journal and onto a USB flash drive? Then change the name... Or maybe put such a file into a specific directory on the flash drive? This is scheduled to be fixed on the next Sugar release. If we don't want the journal to behave this way then perhaps the best place to put the functionality is in another activity. Bundle seems to have sensible overlap with this problem space. May be something sensible to do while we really fix the underlying problem. When I was in Uruguay more teachers asked me about issues with the Journal than anything else. I keep poking on this issue to remind people that it's not going away in the field. Could you please tell us more about the issues reported?

XO power consumption under 8.2-759
I spent a few hours tonight testing the power consumption of a G1G1 XO under 8.2-759. I didn't test any of the tricky autosuspend/resume stuff -- just how much power can be saved by various user actions. Both the answers, and how you can do measurements like this on your own XO (using the power-measurement chip in the battery) are here: http://wiki.laptop.org/go/XO_Power_Draw Rough summary: Normal power consumption of about 6 watts. By dimming the screen, you can save up to a watt. By turning the screen all the way off (xset dpms force off), you can save another 0.5 watt (total 1.5 watts for screen). By default, X or Ohm dims to monochrome a minute after you stop interacting with the laptop, and shuts off the screen after 20 minutes. By turning the WiFi chip off (with Extreme Power Management in the Sugar control panel), you can save up to a watt. By using a WiFi access point rather than a mesh, you can save up to 0.2 watts. None of these techniques involve turning off power to the CPU (the Automatic Power Management option in the Sugar control panel), which still tickles some bugs, particularly with respect to presence and sharing. When you close the lid of the XO (*), it suspends the CPU, and also turns off the WiFi chip unless you're on the Mesh. Turning off the WiFi is new in 8.2, and saves huge amounts of power. My test laptop was able to remain closed for almost 48 hours without exhausting its battery or losing the ability to wake up in a second. (However, due to a bug, it takes it 90 seconds to re-associate with your selected WiFi access point.) I don't know why my power measurements are much higher than Richard's from February (he got 3.9W to 4.9W where I got 5.9W). I tend to trust his more, since mine are one-shot samples, but my dimmer measurements do tend to corroborate each other (i.e. none of them got down to 4.9W until very very dim, yet he says the backlight was on full during his test). Further power testing, by anybody, would be welcome! Please corroborate these numbers, and/or test what Automatic Power Management does for power consumption and/or laptop run-times. 8.2 will be the first public release in which we allow ordinary users to enable the automatic suspend on idle (one of the OLPC hardware's unique features), and we haven't yet characterized how it affects the laptop's average run time before the battery runs out. John (*) Some bugs occasionally prevent the XO from properly going to sleep when you close it. Sometimes it won't power off the CPU; other times it won't power off the screen and backlight. These are being worked on for a 8.2 or a future release. To be sure your laptop won't run out of power quickly due to these bugs, check that the power LED is blinking, and look into a USB port to see that the backlight is off. If not, opening the laptop, waiting five seconds, and closing it again often works. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: 8.2.0 Release Criteria ECO Documentation (Michael Stone)
Hi Christoph, Not sure if the licensing thing will be a deal breaker for including activities in the manufactured image, but we should definitely get that right ASAP. All I'm saying is that we need to decide which activities to include in the image before they start manufacturing them for sale. I want to make sure that decision gets made early. We should also test those activities with an extra level of focus since we know they will get built in. Better to do that before the release is closed. That's why I think it merits a place on the ECO checklist.

Speech to Text Support in OLPC
Hello I am interested in working on developing on the Indian prospects of OLPC. I understand there's some work going on in tts in OLPC. While going through the end user application software page [1], I came across this idea Since space and power is a concern, a speech to text engine would need to be small and not require a powerful CPU. By sacrificing quality a very small engine should be possible. I was interested in bringing speech to text ability in OLPC using one of the existing tools. As CMUSphinx [2] is Java based ( from what I can gather, Java is not shipped by default and there is some considerable effort involved in getting it to run [3] ) , I was wondering if porting of julius [4] (written in C) on XO would be a good idea. Julius is currently developed well for Japanese and their homepage [5] claims that VoxForge[6] is working on developing it for other languages. Also, to make it more useful in the Indian context, I would like to work upon adding support for Hindi in it. I'll be glad to have feedback/suggestions on this idea.

Greg's Weekly report
Hi All, Here's my weekly report below. BTW I would love help on any of these items. I am going to be squeezed by three releases all needing attention at the same time: - 8.2 finalize and launch - 8.2.1 kick off - 9.1 Strategy, process and top feature set definition I can find plenty of sub-tasks (e.g. check and edit the open bugs section of 8.2 release notes, or start to triage and mark bugs for 8.2.1, or collect and organize 9.1 requirements in to groups, etc). The best help is a few hours a week over a few months. Send me a note on list or off if you want to chip in. We could even create a Product Management Gang if there is enough interest... Thanks, Greg S * Status of last week's goals. 1 - Identify, triage and clarify 8.2 blocker bugs. Help get us to a well defined final release schedule. GS - Closed all bugs in finalize state. If they needed documentation I added that to the release notes. Triaged all incoming bugs. Worked with Michael to create an ECO explaining final steps to close the release. See: http://wiki.laptop.org/go/ECO/8.2.0/Checklist 2 - Update 8.2 release notes GS - Edited and tweaked notes for clarity. Still need to organize the open bugs section and rewrite in to user understandable descriptions. 3 - Write 8.2 launch plan. To include lists, web sites and other ideas for getting the word out. Once done, this will sit on the shelf until the release is final. GS - Started presentation. Otherwise not enough progress on this. 4 - Update 9.1 page with more requirements. Add Uruguay, Haiti, Rwanda, Birmingham, Mongolia, Ethiopia, others. Start writing strategy section and set schedule. GS - Wrote brief strategy blurb outlining 3 main goals of the 9.1 (http://wiki.laptop.org/go/9.1.0) release. Met with Sugar design team and planned for more regular meetings. Got a de-brief from Erik on his trip to Uruguay and Peru. Need to add his input to the 9.1 page when I get more details. 5 - Find engineering lead for 8.2.1. If none is identified, start laying out the parameters anyway (e.g. date, target customers, goals, target bug fixes, additional featurettes to consider etc.). GS - Met with Ed (new SW VP) and wrote up some broad outlines of release 8.2.1. Doing one round of internal edits before posting for public comment. 6 - Update deployments page with latest data, improve timeline and add timeline to releases page. GS - Working with Reuben, started regathering deployment status source data and getting approval to post on the public page. Thanks to Skierpage, got a timeline on the releases page but need to tweak it and the whole page before moving completely to new format (see bottom of http://wiki.laptop.org/go/Releases) 7 - Prune outdated material off OLPC wiki home page. GS - Sent e-mail to stake holders proposing removal of old links in Deployments, Developments and News sections of http://wiki.laptop.org/go/The_OLPC_Wiki. No reply yet. Goals for next week in priority order: 1 - Hound engineers to close all 8.2.0 blockers (see http://dev.laptop.org/report/28) and get a firm date for the Release Candidate build. Triage bugs and keep the release on schedule. 2 - Clean up open bugs section of 8.2. release notes. Get release notes ready for final review. 3 - Write 8.2 launch plan and technical overview presentation. 4 - Share and post 8.2.1 time frame and operating procedure (e.g. Trac queries). Start planning for Early Field Trial/Beta of 8.2.1. Keep pushing for an engineering leader/owner of 8.2.1. 5 - Review and finalize short 9.1 strategy description. Restructure requirements section to align with strategy. Fold in more deployment requirements. Keep pushing for an engineering leader/owner of 9.1. Stretch goal: prepare to write detailed requirements sections and start scrubbing bugs to create working Trac queries. 6 - Update deployments page. Update releases page and start using new semantic format (thanks to S Page for laying out the structure).

Re: Speech to Text Support in OLPC
Hi Satya, It great to see that you are interested in the development of TTS for OLPC. We already have integrated TTS engine espeak shipped with XO which support many languages including Hindi. It is pretty small and highly resource efficient. check this out: http://espeak.sourceforge.net/ As a part of this Google summer of Code, Hemant has worked on integration of speech synthesis in XO(http://wiki.laptop.org/go/User:Hemant_goyal). Uptill now we have a ready to use speech-server (speech-dispatcher) for XO and activities are being developed using that server. For the test drive: 1: Install the speech-dispatcher ( http://wiki.laptop.org/go/User:Hemant_goyal#RPM_Packaging_update_3) (Hemant can point you to latest rpm for OLPC) and then install my activity 2: Download my activity from http://code.google.com/p/google-summer-of-code-2008-olpc/downloads/detail?name=Assim_Deodia.tar.gzand untar it. 3: Install the .xo package using sugar-bundle-install listen-spell.xo and then run the activity. If you wish to extend the work done till now, Hemant can help you out with this. -- Regards Assim Deodia ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Improved olpc-log; privacy considerations.
Scott and devel@, In response to several requests, I have finally made olpc-log capture more information. (Caveat: I have only tested the new olpc-log under ideal circumstances; i.e. on a clean-installed joyride). In spite of this lack of widespread testing, I think we would stll be well advised to include this program in our next release candidate because it will help us get more detailed memory and usage information from people who send us log-files. However, some of the changes I have made have important privacy implications; in particular, my choice to record the output of du -k / | sort -nr (This will capture all filenames in the current system [and will bind those filenames to a laptop's serial number since serial-numbers are also recorded].) How might we proceed? - My first thought is that since, at present, the decision to run olpc-log is entirely manual, we may be okay. - My second thought is to state an English warning that olpc-log will capture privacy-sensitive data. - My third thought is to add a flag which prevents olpc-log from capturing privacy-sensitive data. - My fourth thought is to make some effort to anonymize the data e.g. by hashing the filenames and recording, say, mimetype separately. - Other suggestions? Finally, olpc-log is now much more sensitive to the amount of free space (and perhaps also to the amount of free memory). Conceivably, I could rewrite it to stream its data or to be more sensitive to what resources are available but these would be a non-trivial changes. Do you think this is likely to be a problem?

Now this thread has 20 msgs already, and I have a release to work towards. Straight answers please...? What's more straight than saying: The team recommends that the only firmware to be used with the new 2.6.25 kernel is 22.p18 and the only known issue that this team has characterized so far with this firmware, that can be of interest to the XS, is timing issues with WPA? There may be others, but they are not known bugs so far. By the way. Actually, no. Even the WPA issue should not interfere with the XS. And, I would like to understand what is the connectivity model that you are trying to implement on the XS. Are we insisting on using active antennae as mesh gateways on the XS? Is it clear to you that we do not recommend this at all? Simply put. The model of having a bunch of school servers with a bunch of active antennas to support hundreds of laptops in 3 mesh clouds should be completely abandoned. The recommendation of the connectivity team is: use access points (note: active antennae will act as APs shortly, but this is another story). What are your reasons to do differently? - There is an old issue (seen with the 20.49p firmware and oldish driver) with the device getting locked up, which gets solved power-cycling the libertas device. Is it fixed in recent drivers / firmwares? Which ones? Many things have changed since 20.p49 I am sure they have. Now, from the team that has been working on libertas day in and day out for the last N months... does it still reset overnight? Yes, no, dunno? Again: With the 2.6.25 kernel and older firmwares, you would experience wireless crashes. Other than that (i.e. previous kernel with recommended firmware), no one has reported any overnight reset with the wireless firmware for months. Firmware 20.p49 is deprecated for months now. I had no idea that someone was using it (a communication flaw?), and I don't recall reading any questions on what version should be used with the school server, before now.

Re: Wellington test team vs Activities - 2008-09-13
My notes Today we did a lot more activity testing, while keeping an eye out for OOM behaviour. On several machines we captured the output of ps_mem.py in a bg process. It quickly got boring as we didn't see any mem usage spikes. General - We were distributing the activities on ext3 usb sticks -- this does not work. Attached logs to #8099 - Machines have /home/pilgrim and/or /home/cscott directories...? Upgrade methods mixed (NAND, olpc-update) so I'm uncertain of the source of the problem... - Memory pressure/OOM killer: we didn't see the OOM killer in action. Firefox with several tabs open did get machines unusable due to memory pressure and killall -9 firefox failed to kill it. At that point ps_mem.py reported ff taking ~80MB - was ok as the single activity open, but could not coexist with another heavy activity such as Physics. At such times vmstat reported 0 buffers, 3M free, and ps_mym.py ~189MB used in total. Story Builder - Gorgeous activity, and well thought out lesson plans. Wish all activities had this. - Very slow - almost unusable - Very high cpu usage on idle. Other activities from the same set don't suffer this problem. Map - Hit #8318 which causes it to fail to start. yum install hulahop didn't see the new hulahop (reported as fixed by Scott) - probably in a different repo, so could not confirm the fix. Cartoon Builder - Very cool, also excellent lesson plans - The lesson plans in Spanish look remarkably similar to the English ones :-) #8459 - On close, got 'Keep error' #8460 OurStories - Fails to start - #8461 - from what I can see, suspect that the original authors have done something really nice but have failed to package the .xo properly... - Seems to be a really compelling concept from the wikipage... Physics - Too addictive - lost a ton of time playing with it. - Does not close - #8462 - High cpu usage when not in focus #8463 Firefox - Consumes a lot of memory - Is not killable when under memory pressure (perhaps it just takes very long to be killed?) -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Helping me figure out how to make a spin post-GPG-keys-change-drama - see http://marc.info/?l=fedora-devel-listm=122109127113298w=2 I think I answered this; http://marc.info/?l=fedora-devel-listm=122114550831324w=2 All you really really need to do is make sure you include the new fedora-release package for the new GPG keys to be on the installed system and avoid needing to go through the transition of keys. As far as the installation is occurred, you'll hit BZ #998 (the installer doesn't verify keys). Hope this helps ;-) Kind regards, Jeroen van Meeuwen -kanarip ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

We need a tiny patch to add a 2nd ks file - you'll see in the ticket I'd like to have one with interactive in it, and one without.

Hadn't seen it when I posted :-) All you really really need to do is make sure you include the new fedora-release package for the new GPG keys to be on the installed system and avoid needing to go through the transition of keys. Cool. As far as the installation is occurred, you'll hit BZ #998 (the installer doesn't verify keys). From what I read there, that'll just log warnings in install.log right? Good on Jeremy to reopen a 1000 bug.

Re: [Server-devel] PostgreSQL mgmt on Fedora: pg_cluster-like tools?
Martin Langhoff [EMAIL PROTECTED] writes: 2008/9/12 Devrim GÜNDÜZ [EMAIL PROTECTED]: * Upstream never ever gives such a guarantee that all apps will work on every PostgreSQL version. For example, some casts were removed in 8.3. Having been once the maintainer of the Pg compat layer in Moodle, I also have first-hand experience with this. When the casts removal was mentioned in pg-devel, who was there asking about backwards compat? If you need 100% backwards compatibility, you keep using 8.2 (or whichever). That's why we keep maintaining back branches for so long. If we were to try to keep 100% compatibility in new releases, our ability to add new features would be crippled. So I'm not about to apologize for the fact that 8.3 exposed the brokenness of some broken apps. Anyway, Devrim is quite right that mere installation of an RPM cannot execute any sort of database conversion. The functionality would need to be invoked sometime else. That doesn't mean it has to be manual though. Could we put it in the start script, invoked by something like service postgresql upgrade? Exactly what does a conversion look like in Debian's packaging, anyway? regards, tom lane ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Deepak, You should also add the thin firmware driver to the XS build so that they can configure the active antennas as access points.

Some clarifcation. The issue is not the firmware, but the kernel driver itself as there are pieces from the 2.6.22 driver that never made it upstream. Yup it's an incompatibility between the stock F9 kernel and the recent firmwares. My suggestion is to run the same driver and firmware on both XS and XO so we do not have multiple variables to deal with. I generally agree, but unfortunately, that adds significant work (of carrying custom-compiled drivers) to a tiny team of 2. We don't have a kernel maintainer in the XS team :-/ Well, my job description is simply kernel guy, not tied to XO or XS, so I will build something against your F9 kernel that you can test and will volunteer myself to keep XS libertas in sync with XO libertas until we get our kernel in sync with Fedora. ~Deepak -- Deepak Saxena - Kernel Developer - [EMAIL PROTECTED] ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
