QEMU image for firmware 703
The school federation in my region lend me one of the two XO-1 they got with the G1G1 program. I'm going to give a presentation next week and I'm trying to get collaboration between sugar-jhbuild and the XO with no success. Both are connected to xochat.org but only sugar-jhbuild sees the other.

boot-anim
As it stands now there seems to be no 100% reliable way to judge the compressed size of things on jffs2. I cast my eye to the boot-anim, uncompressed it comes to about 60 Meg, is there space being wasted there? http://lists.laptop.org/pipermail/library/2007-July/70.html says JFFS2 compresses 4K chunks using zlib. So it's not just per-file compression, it's compressing bits of a file. It doesn't compress files where compression doesn't help. And there's a 68 byte overhead per compressed chunk. Plus probably some fixed overhead per file. doing some tests using mkfs.jffs2 on a filesystem with a single file of zeros at varying sizes gave me. 409600 -- 11656 819200 -- 23256 1228800 -- 34856 1638400 -- 46456 each growth of 100 4k blocks added 11600 bytes. I'll go out on a limb and say the best case on jffs2 is turning a 4k block into 116 bytes, about 35:1 compression, or down to 2.8% if you prefer This is why the boot-anim bothers me. If it were all zeros it should be taking up just over 1.5 meg. It compresses really well, but it can't go beyond that limit. Running the jffs2size.py script on /usr/share/boot-anim reveals. no compression : 60480336, 60480K estimated jffs2: 1983630, 1983K (3%) mkfs.jffs2 : 2344068, 2344K (3%) zipped : 389259, 389K (0%) .tar.gz: 399360, 399K (0%) .tar.bz2 : 184320, 184K (0%) It looks like there's easily a meg to be had there, two meg looks doable. Where to go from here is another issue. total flexibility and 90% of the size gain could be had by using pngs (not sure if there is a speed issue there) If there were to be a simple runlengh encoding, the bulk of the size would go and jffs2 would crunch the remainder. wadeb whipped up a tiny rle compressor/decompressor pair. gzipping at a file level removes the block overhead and the size drops to about 380k.

Re: thread summary: On Cerebro, Telepathy, yokes and whites
Greg, I am adding the 'testing' mailing list. We can use this 'real life' information for generating Use Cases and test cases but we will probably need to simplify it. There are too many things going on in this particular case. We have some use cases for school scenarios in some of these links: http://wiki.laptop.org/go/Tests/Connectivity_and_Collaboration - use cases in classroom http://wiki.laptop.org/go/Networking_scenarios - major types of scenarios http://wiki.laptop.org/go/Collaboration_Network_Testbed - 100 laptop testbed As well as generating use cases, this 'real life' scenario tells us that we have not conveyed what SHOULD work properly to people on the ground - as what they are trying to do is not even possible in today's builds. We've known that communications is a problem, but it emphasizes that we need to figure out some solutions... and telling this particular teacher, for instance, that what they are trying to do won't work, is not the right answer. Also, from a support perspective, it is really important when we get feedback or help requests directly from teachers in country that we try to get them in touch with their local support people - or we try to include the local tech support people. As Wad as identified in the past, if we try to help people where we really don't understand the local constraints or the RF layout we are more likely to make things worse than to actually provide help. With large country deployments, the first level of help needs to come from in house support. Thanks for bringing this up, Greg. It emphasizes a lot of things we need to address.

Its OK to require them to leave the share to open their own local copy as long as it doesn't crash if they do it out of order (what is supposed to happen if you are sharing a document then open a new one too?)

Re: Build streams
The F9 build does boot into Sugar -- we aren't going to leave everyone with a broken build for long. It has bugs, though. We need help fixing the bugs more than we need a demand for constantly stable developer builds and an unwarranted supposition of conflict. Not long ago, when I tried to describe trying the F9 build, someone said this is not close to ready for use. On my XO, olpc3_17 booting will only complete if I manually switch into the text console (ctl-alt-F1).

Re: Trac: release management
Hello, I agree wholeheartedly that ticket triage and statistical analysis is a worthwhile effort, so I think I support what Garrett is talking about. At my employer we have teams of producers constantly watching individual and per-component bug counts, transfering bugs from overworked team members, ensuring progress is being made according to priority levels, and tracking the rate of change of the blocking ticket count compared with previous projects to estimate our completion date, among other things. Without that kind of attention, there is no way we would ship anything on time. I don't care how the open source world usually does it, releases don't happen unless you're on top of your tickets. I know there is a Git plugin for Trac, anyone know why it isn't installed? I would love to see commits on the Trac Timeline RSS feed, and the Trac source browser is pretty nice too.

RE: Trac: release management
I'll second Wade's comment below. Once all the features for the release are in the number 1 job of the mgt team (or the manager if she's all alone) is staying on top of problem reports. High priority tickets get done first, tickets are triaged within a day and high priority tickets get assigned while low priority tickets are deferred...With the assistance of the test team you can track outstanding tickets, incoming and outgoing rates and use this to forecast your release date or to take corrective action to meet your release date.

Garrett, Thanks for your time and thoughts.

I will try to send frequent updates in terms of what has been added. In addition to using the documentation, I'd appreciate it if people familiar with the different modules I am writing can send any better or alternative code examples to the ones that I have written. Review and feedback is ALWAYS appreciated. This week, I have updated the section on how to do many of the basic activity creation tasks (see http://wiki.laptop.org/go/Sugar.activity.activity). In addition, I've provided some basic examples of how to read and write your activity to the datastore so that it can be resumed later from the journal.

Re: [PATCH #6010] Add sysfs interface to enable/disable wakeup events
Hi Deepak, Here's the initial patch (vs testing kernel) for #6010 to provide an interface that OHM can use to enable/disable wakeup events. It still needs error handling for the ec_cmd() calls but other than that it is ready to be tested. Looks good. I was hoping for a lid-switch attribute as well -- Richard and Jordan, does that route through the Southbridge, or should it be listed here? (If it should be, where in the SCI mask is it?) Similarly, I'm guessing there's no way for the EC to inhibit power button press wakeups?

Re: [PATCH #3355] Add sysfs support for powering down the OLPC 88W8838 wireless chip.
On Jun 13 2008, at 19:00, Chris Ball was caught saying:
This uses the OLPC EC 0x35/0x25 interface.
Question: is simple_strtoul() safe here?
I think the preffered way to do this is via sscanf() of
the incoming buffer as you can catch errors such as
non-integer input. simple_stroul() will just return
0 which is not what we want.
I'd also change the mode to 0400 as this is a write-only bit.
My preffered option is to make it r/w, call it wlan_enabled
and than we could check the state via the file too by storing
the current setting.

Re: Upgrade G1G1 using autoreinstallation method
Not knowing more about what you've done, I have to ask a lot of v. simple questions. When you say move on, you have manually associated each laptop with the AP once, right ? And the ESSID hasn't changed ? How realiable is the failure ? Do all XOs move on to mesh mode, or is this only a problem with a (random) few ? How many XOs on each channel ? You could be seeing a failure of DHCP to actually occur. Have you checked /var/log/messages on a failing laptop ?

downloaded files and the Journal
I was exploring the OLPC Library in Browse in build 703. The transition from browsing to viewing a PDF in Read is pretty clunky, I noted the glitches in http://wiki.laptop.org/go/Talk:Read#Many_issues_going_from_Browse_to_PDFs The oddest thing is that every time you click on a PDF, another copy of the PDF is saved to the Journal's datastore. This sounds intentional as part of the fix for Read doesn't save the PDFs it opens (Trac #6729). I think the Browse activity is putting the file in the Journal, as the extra copy appears in the Journal's datastore even before I run Read. But this doesn't make sense for read-only local files in the OLPC library like images world maps click Africa. I've now got 7 copies of this .5MB PDF in ~/.sugar/default/datastore/store, each identical to /usr/share/activities/worldfactbook-maps/africa.pdf ; seems a significant waste of space. (Or does JFFS2 magically optimize multiple copies of the same bits? df -k reports mtd0 dropping by about the size of the PDF.) If Evince worked as a browser plug-in, maybe the duplicated files would go away (along with some other glitches). However, Consider unifying Read and Web (Trac #3212) was rejected. If viewing PDFs remains a separate activity from Browse, then maybe the Browse activity could detect that it's downloading a local read-only file, and rather than the confusing download step leading to a copy in the Journal's datastore, it could just pass the local file:/// URL to Read on the command line. But even if Browse bypassed the download step for local files, the problem of multiple copies remains for remote files. I think each time I return to a PDF on the Internet, the Browse download step likewise makes another copy of the PDF in the Journal's datastore. Has anyone considered making the Journal a two-level store, so that if I download the same file 7 times there's only one copy in the datastore, using symlinks or references or other magic? Maybe this could even be made visible in the UI: You've downloaded this file 7 times already, please check the Journal before repeating yourself. Sheesh kid do you think the Intertubes is free?! Meanwhile, the OLPC Library should prefer HTML or SVG content over single-page PDFs. (The problem of local copies of Web content isn't unique to Sugar. On my desktop PC I'll save stuff from the browser locally then forget that I've done so. I want a browser and O.S. that opportunistically treats everything on my hard drive as a local cache of something from the Internet that might be updated, or have disappeared.)

[Server-devel] EDuBlog XS Beta/Development Server
Hi Tony, I think we should finalize the Fedora + XS server and get it shipped to Glen by the end of next week. My list of SW is: PostGreSQL Moodle XS Apache 2.0 PHP Networking should be setup to plug and play at Glen's hosting site. If we can get an image on CD too that let us boot and install it back to default config (preferably without overwriting new stuff but not critical) that would be helpful too. Tarun, Marcel et al, Let me know if there is any other SW needed. Can you also fill in the version numbers and let's document this server HW and SW here: http://wiki.laptop.org/go/Educational_Blogger_Project#Beta_Server_Hardwa re_and_Software_Details Debian is a stretch goal. I want to make sure we get it to the hosting site in time to have a full week of config/debug before you go back on the road (June 30?). If we have enough info and can make it dual boot to Debian that's the stretch goal, but must hit the install in PA date of June 23. I don't think we need to share data between the two distros so it can be a completely different image/partition for Debian. Marcel will be lead sys admin so he will need user/pass access. Tarun needs SU access too and I could us a login. Please don't send any passwords on this list. I'll open a separate thread with Glen to work out the logistics. I hope that's doable. Let me know if you have any questions, concerns or need more info. I wonder if we need a terminal server? I hope we can run it without that but if its needed and Glen will host it, I can look for one (probably need to buy it :-(. Lastly, we need to pick a domain name. Root name is one of these: totaluruguay.com, venango.org or olpcuruguay.com. We can pick a third level name. Yama, Can you pick a good name that will resonate with kids in Uruguay? Also, does EduBlog sound good in Spanish and can kids say it easily? We can call it the code name but once you use a name it sticks so if needed, we should change it now and only once. BTW please use [EMAIL PROTECTED] for me as of Wed. June 18th. I'll subscribe that to the list so you can reach via server-devel too.

[Server-devel] XS SW
I'd like to wade in on the question of base SW for the XS server, especially as regards database support. I think the principle should be to use the software with the most users and developers, and therefore the most support, unless there is a compelling reason not to. So the popularity of LAMP/WAMP would suggest using mysql unless there is a strong reason to use something else, like postgresql. Martin has argued strongly in favor of postgresql in http://moodle.org/mod/forum/discuss.php?d=24831 (June, 2005), but he doesn't say which version of mysql and whether he is using innodb. Greg Smith (? of EDuBlog fame) wrote a more neutral evaluation in http://wiki.postgresql.org/wiki/Why_PostgreSQL_Instead_of_MySQL:_Comparing_Reliability_and_Speed_in_2007, which does take into consideration MySQL 5.x and innodb. Even when I installed moodle using yum on XS build 163 it came bundled with mysql libraries, not postgresql. So my question is, given that this is OLPC and not OLTP, are there still reasons not to use mysql in light of more recent improvements (not to mention purchase by Sun, which is both positive and negative)?

Re: [Server-devel] EDuBlog XS Beta/Development Server
Hi Greg, I'm glad we finally have settled down on a configuration for the EduBlog Beta Server (EBBS) I think we should finalize the Fedora + XS server and get it shipped to Glen by the end of next week. I've updated the wiki here with what I think are the must have and nice to have requirements. Please review. http://wiki.laptop.org/go/Educational_Blogger_Project Based on suggestions from Wad and Martin, I had been invstigating Debian and KVM alternatives, so if all we want is now an XS machine, I will re-focus my efforts and put those on the back burner. Networking should be setup to plug and play at Glen's hosting site. I have three NICs, but only details for one IP connection. Please confirm. I will test out all three NIC connections, and then set one to match Glen's requirements. Also, I need you to finalize the domain name. The XS might decide one is for WAN and the other two are for LAN for me. If we can get an image on CD too that let us boot and install it back to default config (preferably without overwriting new stuff but not critical) that would be helpful too. Yes, I have been exploring Mondo Rescue and SysRescCD partimage methods. I will include CDs/DVDs in the box sent to Glen. Debian is a stretch goal. I want to make sure we get it to the hosting site in time to have a full week of config/debug before you go back on the road (June 30?). I can probably drop in Debian in a separate partition, but will leave that for last. I will be travelling to Japan/India July 5-20. This is a business trip for IBM, so I will have my laptop and cell phone, and may be able to help with the installation remotely. I will test my ability to connect from my laptop to the EBBS to confirm. Marcel will be lead sys admin so he will need user/pass access. Tarun needs SU access too and I could us a login. Please don't send any passwords on this list. I'll open a separate thread with Glen to work out the logistics. Send me a list of users and their email addresses, and I will set them all up. I wonder if we need a terminal server? I hope we can run it without that but if its needed and Glen will host it, I can look for one (probably need to buy it :-(. Glen should have a screen, keyboard and mouse. This could be KVM switched with existing equipment he already has. For example, I have a 4-way KVM (keyboard, video, mouse) switch that connects my Apple Mac OS, my Windows XP, and this new EBBS all on the same keyboard/mouse and video screen. I hit Scroll-Lock / Scroll-Lock / Up sequence to change to the next screen (or you can press the button on the switch itself to pick one, but I am too lazy to get out of my chair). The EBBS uses round PS2 style keyboard and mouse connections (USB keyboard and mouse connections might need some changes to configuration) My biggest concern is that once it is in Pennsylvania, Glen will be the one doing most of the work if there are any problems with Internet connections, SU logins, etc. I will do the best I can for it be read out of the box, and have enough on there so that any minor updates could be done via wget or yum. Glen should be able to use any Windows machine via OpenSSH to access the command line console. (Glen, if you need something, I can get you connected for a refurbished IBM system for a few hundred bucks, let me know).
