But if it's rsync, maybe it's driven from the client end (and if the client suspends, the server never sends anything further). olpc-update should be touching /etc/inhibit-suspend before it does its work, so it should not be sleeping. If it does, and your build was not ancient, it's a bug and I'd like to know more. the machine had a fully charged battery and was plugged into external power, it got to the step where it was doing the rsync, and then a few min later the screen was off. I hit a key and it was still in the rsync and did not recover. The real fix is to only force a suspend when the kernel knows no process is scheduled to run now or soon, and ato waken in less than a whole second. We're slowly working on those issues. If we keep kludging things like TCP, there's never the time to put in the real fixes. Yes. Better integration of suspend and the kernel scheduler is discussed near the end of http://download.laptop.org/content/conf/20080403-olpc-mini-conf/Power/ but I don't think we've made any measurable progress on it since then. Dilinger has been resyncing us with upstream, and deepak just started full-time OLPC work. We could use help! --scott I don't think that a TCP session waiting for data is nessasarily going to schedule anything within any arbatrary 60 second block so the scheduling detection isn't good enough (especially if going to sleep means that you miss the reception of the packet and have to depend on the retry algorithm re-sending it in one of the windows where you wake up) if wake-on-lan works for packets of an existing TCP session, then sleeping (lightly) while waiting is fine. otherwise an established TCP session is a good indication that this isn't a good time to auto-sleep. if activities need to override this it should be by doing something to tell the systems that it doesn't care about the session being brokern. that way unmodified apps won't break unexpectedly (they will prevent the machine from sleeping too soundly and increase power useage, but I think that's a muchmore graceful failure mode) David Lang ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [OLPC Security] G1G1: Security, to enable or disable...
The two issues that I am concerned about regarding the write protect flag with regards to G1G1: 1 - I thought requiring signed images was part of our bitfrost security. Doesn't it provide some protection from malicious images? Assuming we get to the point where upgrading is an easy click from the G1G1 machine, then we want to be sure that people don't mistakenly load non-signed images. If you are not a developer; doesn't this add a level of protection that we want for 90% of G1G1 recipients? 2 - I believe our support issues will go up significantly as people who have little or no experience are encouraged to download all sorts of untested builds with no easy way to get back to a working system. To feel better about the support issues, I would like the one-button push that restores a laptop to factory default. Actually walking people through a cleaninstall is a very time-consuming process right now. Finally, I agree with Scott, that the easiest thing we can do in the short term is to make the 'get a developer key' more prominent for those who want to find it.

But you could start to get a handle on it by adding 'Found In', 'Fixed In', and 'Tested In' relationships for tickets. How do you currently figure out when/where a defect was introduced and fixed? How many Full Time Equivalent hours does a given developer represent? A guesstimate: about 25 hrs/wk of coding and 30 hrs/wk of talking for social folks, maybe 30 hrs/wk of coding and 10 hrs/wk of talking for contractors; and 5-8 full days off a month (including weekends). Is there any list of developers and which slot each fit into? What components are the given developers capable of working on? I don't understand this question. You've got folks who have particular areas of expertise. Or to put it the other way, developers who can work in certain areas but not others. If your Trac ticket classifies a ticket as belonging to a particular area, you can then project how many FTE's you've got on hand to work in that area. I realize that this being an open source project leaves a lot open ended. But if you collect the data in a way that you can get at it effectively, you can use historic data to verify your assumptions and track and make projections against non-employee/non-contractor developers as well. How long does the assigned developer think the specific ticket will take to complete? How long did it take? The limiting factors seem to me to be: a) how long is the critical path of changes necessary to close the ticket? b) how overloaded is the required developers? c) how frequently are the required developers task-switching?

How to you track defects back to the changes (ticket) which introduced them? We don't do so systematically. It is hard to do if you want to track back to a specific git changeset... or Trac ticket. But you could start to get a handle on it by adding 'Found In', 'Fixed In', and 'Tested In' relationships for tickets. How do you currently figure out when/where a defect was introduced and fixed? How many Full Time Equivalent hours does a given developer represent? A guesstimate: about 25 hrs/wk of coding and 30 hrs/wk of talking for social folks, maybe 30 hrs/wk of coding and 10 hrs/wk of talking for contractors; and 5-8 full days off a month (including weekends). Is there any list of developers and which slot each fit into? What components are the given developers capable of working on? I don't understand this question. You've got folks who have particular areas of expertise. Or to put it the other way, developers who can work in certain areas but not others. If your Trac ticket classifies a ticket as belonging to a particular area, you can then project how many FTE's you've got on hand to work in that area. I realize that this being an open source project leaves a lot open ended. But if you collect the data in a way that you can get at it effectively, you can use historic data to verify your assumptions and track and make projections against non-employee/non-contractor developers as well.

On the other hand, people have been answering this question on projects much larger by just counting the paid FTEs and a back-of-the envelope estimation of the unpaid contributors, which has none of the disadvantages of, and many more advantages than your proposed method. This meta discussion takes valuable time - I don't think it's worth the costs, given all of the above (yeah, I know this is hypocritical, but this is the internet so I can do that :)). How long does the assigned developer think the specific ticket will take to complete? How long did it take? The limiting factors seem to me to be: a) how long is the critical path of changes necessary to close the ticket? b) how overloaded is the required developers? c) how frequently are the required developers task-switching? I was ambiguous. What I meant was a). How unlikely is it that a) be knowable with a useful degree of accuracy before the ticket is closed? It's pretty darn unlikely, I contend. It'd be nice if there were a field in the ticket for the developer to note down how long they think they actually worked on a ticket. If anybody actually did so, why would you expect people to be 1) able to be accurate; or 2) using sufficiently similar definitions of how long I worked on this to be comparable? If you combine this with the earlier mentioned field for scope/complexity (difficulty) then you can make some projections on how many FTE outstanding ticket hours you've got based on historic data. And you can assign each 'difficulty' level an average time to

Update.1 Clarifications and Resulting Opportunities
This email is intended to clarify a few facts about Update.1 for the record so that I can rest more peacefully at night and so that we, collectively, can move on to new business: 1. The Update.1 build is official-703, available from http://download.laptop.org/xo-1/os/official/703/ We still need to put up the official ext3 image, but unofficially, it's available from http://pilgrim.laptop.org/~pilgrim/xo-1/streams/update.1/build703/devel_ext3/ should you need it. 2. We concluded that 703 was going to be the official Update.1 on March 31, 2008 but we knew that the Release Notes: http://wiki.laptop.org/go/OLPC_Update.1_Software_Release_Notes weren't good enough so we decided to spend a few weeks improving them. By April 22, we had understood from the support-gang that 703 was not going to be suitable for the general G1G1 audience without a one-step installation tool to take care of the details of the activity installation needs described in the release notes. Then, on May 1, Scott published candidate-703 as official-703 because Peru and Mexico had begun installing it without regard to the incomplete release notes or the lack of a one-step installer. Today, I updated the Wiki to reflect these occurrences in the hopes that we may find a small degree of closure. If you are interested in helping to build the G1G1-requested one-step installation tool, please comment on #7093. We'd really like to find a workable solution in the next several weeks - both our 8.1.1 bug-fix release (in progress - please help test update.1-708!) and our 8.2.0 August release would benefit. Regards, Michael P.S. - If you're trying out 703 or 708 for the first time, _please_ read the Update.1 release notes: http://wiki.laptop.org/go/OLPC_Update.1_Software_Release_Notes Please!!! ;) Alternately, if you're interested in improving the procedures that were followed in order to produce Update.1 (and subsequent releases), please comment on the contents of these pages: http://wiki.laptop.org/go/OLPC_SW-ECO_4 http://wiki.laptop.org/go/OLPC_SW-ECO_4_Checklist http://wiki.laptop.org/go/Unscheduled_software_release_process Finally, if you want to help out with our next releases, check out http://wiki.laptop.org/go/OLPC_SW-ECO_5 and http://dev.laptop.org/ticket/7014 for an exciting sneak-peak at what's coming up next; then help test http://pilgrim.laptop.org/~pilgrim/xo-1/streams/update.1/latest/devel_jffs2/ (developer key needed; see http://wiki.laptop.org/go/Activation_and_developer_keys) (Please write test results at http://wiki.laptop.org/index.php?title=OLPC_SW-ECO_5action=editsection=3) (or file tickets; whichever you prefer!)

HTML controls don't display using the sugar interface controls either, so I'm unsure if this uses them. Well, Browse is a python activity that uses pyxpcom to access the xulrunner functionality from python. Browse uses the browser functionality in xulrunner because it is a browser ;), but your activity could use the html editor functionality that is in xulrunner.

I am in Nigeria at the moment, in Abuja, doing an installation for a University coming on line in July. Have been quite busy lately, without great internet access .. apologies for the lateness of the reply. However, I have made a lot of progress on moving my Email / web scoop solution from CentOS to Ubuntu Hardy, and making it live nicer with a package system. Let me know what you are trying to do and I will see what I can do to help. Well, the OLPC software stack is Fedora-based, so the CentOS packaging is more relevant. =) Yes, the packaging is more relevant, but my redhat install definitely 'took over' the installation process - with much of the configuration happening on boot after the initial install. I have made it play nicer with an existing install, and I think it would be better to re-port what I have done so far back to Redhat. Configuration now happens when it is supposed to - on package install - and currently does it using debconf and its database. I'm going to be taking a closer look at wizzy-06Aug2006.iso today (or is there something more recent?) to figure out how best to integrate it. The major issue at the moment seems to be how to manage a shared request queue for disconnected operation. The walkthrough at http://www.wizzydigital.org/community_z_Internet_Manager.html seems a little too involved for teachers with no previous internet experience, so a more automatic default mechanism for adding sites seems worthwhile. There is nothing much more recent for CentOS, but ftp://ftp.wizzy.com/pub/wizzy/wizzy-hardy-20Apr2008.iso has Ubuntu Hardy packages. The relevant package is wizzy-ibox - which has a list of dependencies to pull in things like exim and dovecot (for email) and wwwoffle (for web). It also has a set of administration pages - not all quite finished yet, I am afraid, and the postinstall script creates a skeleton LDAP directory, used for UUCP routing as well as accounts. Here's a quick scenario: * In Peru, the teacher and all the kids have XO-1 laptops with minimal storage (~500MB) * Every school also has a school server with a large hard drive. * Presumably, the school server would run (pieces of?) the IBOX software and provide a transparent proxy of port 80 for the machines. * Once a month the teacher travels to the nearest town with internet access, which may be a week away, for teacher training. * The idea is that the teacher should be able to download the latest request queue onto a USB stick before they leave, and use the internet access in the nearby village to download pages matching the request queue onto the USB stick, and then upload the pages into the school server. * At the moment we're more interested in web than email, but email in the same transaction would be a nice plus. (In Uruguay all the schools are being provided with email by the state telco, however, so our email mechanism should be optional when the country is already supplying it.) I assume that the teacher will be using the XO-1 to perform the download when they have internet access. I'm a little worried that we might have places with an internet cafe, but no provision for networking the XO-1 (no wireless, or the teacher doesn't have the appropriate adapter for connecting to a wired ethernet, or the internet connected machine has no provision for connection sharing). So being able to perform the 'courier' function via a web interface from a connected machine with no special software seems desirable as well. In summary, your Whizzy software looks excellent, and, as is, looks to address a large part of our disconnected internet use case. Thanks for your work on this! Perhaps a few tweaks will allow easier operation for naive users in Peru's scenario. There are probably some longer-term issues involved with integrating wwwoffle's web cache with the other web caching solutions discussed at http://wiki.laptop.org/go/XS_Server_Services#HTTP_Caching. We'd also like to integrate this caching with central management of school library content: Uruguay, for example, has a 'push' scheme for updating textbooks/documents/etc on the school server, in addition to Whizzy's pull scheme. Long-term we'd like to have a consistent story for all of these uses -- although whizzy could be a central component in that story. Another likely longer-term issue regards schools without school servers. I believe our initial Peru deployments all have school servers, but for smaller schools and other
[Server-devel] Problems installing XS on new system for Uruguay
Greg, The XS hardware is up and running, and now am encountering some software issues that I may need help from the server-devel list to resolve. Hardware: V3-M2A690G barebones PC with M2A-VM motherboard, power supply and tower case, The M2A-VM motherboard has ATI SB600 RAID controller, ATI Radeon 1200 Graphics, 8 USB ports, built-in NIC. AMD Athlon64 X2 dual-core 2.3 Ghz processor with heatsink/fan Two extra NIC cards (PCI) 10/100 with RJ-45 ports One DVD-RW drive, attached on primary IDE-Master Two SATA drives, 160GB each, connected on SATA1 and SATA2. One 2GB DIMM. I had it almost all together yesterday in four hours, but had to go back to the store to get an extra SATA power cable adapter and return an extra SATA signal cable. I took photos, so I might be able to document the process for future hardware builds. The XS-163.iso would freeze because there was no Partition Table on the disks. I was able to fully install 64-bit Fedora Core 8-AMD64 on the system, which was enough to put partition table on /dev/sda and format an ext3 file system. After that, I was able to fully install 32-bit Ubuntu 8.04 on the system. Both run in full graphics mode, and I was able to test all the memory, verify ethernet connectivity, etc. Problem 1: I boot from XS-163.iso and select Run from Image (the first choice) and it claims that ATI Radeon 1200 is not supported, and that it will go into text-only mode for the install. I figure this is not really a problem, since this is a text-only server eventually. I suspect there are Radeon 1200 drivers on later versions of Linux, so it might be something I can fix after the fact. Problem 2: I log in as root and run the ./olpc-install and it fails on line 23 saying Specified nonexistent disk sda in clearpart command with a big red button to reboot. (see attached JPG file: img_4751b.jpg for screen shot) Rebooting without the XS-ISO cd results in running the current 32-bit Ubuntu 8.04 that I had installed previously, so it looks like it didn't wipe out anything. I tried this with both XS-163 and XS-150 (from back in February) and got similar failure messages. My next try will be the XS-160-noauto ISO file. I could also try to do the kickstart manually? Would that work? If I do that, would I be better off doing Fedora7-AMD64 instead or stay with the 32-bit version? Problem 3: the BIOS supports three settings: IDE, RAID and AHCI. With RAID, I can hit Ctrl-F to get to the FastBuild utility, and put the two drives into a single RAID-1 configuration, however, it does not seem that Linux recognizes that. With the two drives as one Logical RAID-1 drive, the Linux treats this as separate /dev/sda and /dev/sdb drives. I found this link, indicating that the ATI SB600 fakeraid support through the dmraid device mapper is supported in AHCI mode, but if I say AHCI on the BIOS setting, it treats the two drives separately. http://linuxmafia.com/faq/Hardware/sata.html#ahci I could instead go for a software-based Linux LVM mirroring. In that case, I might use the BIOS=AHCI setting, and then set up the LVM, but that is different than the LVM setup in that base XS kickstart file. Please advise.

Not that he can't or shouldn't, just that it wasn't in the job description :-) I'm not sure I understand everything you are talking about below but I want to re-iterate one design goal. I hope this whole app can be done server side with no changes to code on the XO. I don't even want to sugarize beyond making sure the web pages display well in the default Browser. That saves us from updating the Xos and doing a huge regression test on the client side. Let me know if you think that is not possible and we need XO code changes. The XS only requirement and the need to create a dynamic (AKA configurable by teacher/admin) set of options were the main reasons we chose Browse for the client instead of Write. We give up powerful formatting tools by using unmodified Browse + HTML but that's a price we're willing to pay for shorter development time and flexibility in updating. BTW Tarun, is your XO on its way to India? Get me the shipping address off list and I'll ping SJ again if needed.

The only question I have is how easily I would be able to make that interface mimic Write and add options to it. (I assume it would involve changes to Browse or other sugar code). HTML controls don't display using the sugar interface controls either, so I'm unsure if this uses them. Well, Browse is a python activity that uses pyxpcom to access the xulrunner functionality from python. Browse uses the browser functionality in xulrunner because it is a browser ;), but your activity could use the html editor functionality that is in xulrunner. You would code the UI in pygtk very similarly to Browse, and just call xulrunner through pyxpcom. Not sure which one is the best for you, perhaps going with #2 may be easier? Would be good to leave space for growing later as needed, though. #1 and #3 would give you support for tables. I'm not sure why #2 (JS editor) would not give me support for tables. Doesn't Gecko's Midas provide functions to create and modify tables? (I've done it with editors that run in firefox.) Has that feature been disabled for some reason? Well, Midas is a html editor implemented in C++ inside xulrunner, right? It can be accessed though js or pyxpcom, so it would work both as #2 and #3. Didn't knew it had support for tables, so I stand corrected.

Re: [Server-devel] Problems installing XS on new system for Uruguay
Martin, I'll try the lspci commands to see what it says. What dmesg should I look for? -- when I do: dmesg | grep sd[ab] I get that it finds both /sda and /sdb individually, so not detecting the RAID mode. The autoinstall' fails either because of the Radeon X1200 or the clearpart command on Line 23. I've burned a copy of XS-160-noauto if you want me to try that. I've been scanning the Fedora forums for dmraid support, and it doesn't look like it has support for this SB600 SATA RAID controller. Uruguay = EduBlog/Ceibal/Greg Smith. I am building the server to Greg's request, so whatever he is now calling this project that is what it is.

But the sata controler might not be supported. When you load F8 64-bit or Ubuntu, - what does lspci say about the SATA controller? - what kernel module loads for it? (dmesg will name it) Problem 1: I boot from XS-163.iso and select Run from Image (the first choice) and it claims that ATI Radeon 1200 is not supported, and that it It often complains about graphics cards. Nothing to worry about - Compiz won't be enabled on the XS ;-) Problem 2: I log in as root and run the ./olpc-install and it fails on line 23 saying Specified nonexistent disk sda in clearpart command with a big red button to reboot. (see attached JPG file: img_4751b.jpg for screen shot) Recent images are auto install so you don't need to run olpc-install by hand... Would that work? If I do that, would I be better off doing Fedora7-AMD64 instead or stay with the 32-bit version? Unfortunately, we have a few custom packages that are compiled 32-bit only (nothing too bad, just a recompile away) - but I think your problem is with missing drivers in F7. Can you try installing F7 32bits? Problem 3: the BIOS supports three settings: IDE, RAID and AHCI. With RAID, I can hit Ctrl-F to get to the FastBuild utility, and put the two drives into a single RAID-1 configuration, however, it does not seem that Linux recognizes that. With the two drives as one Logical RAID-1 drive, the Linux treats this as separate /dev/sda and /dev/sdb drives. No idea bout AHCI or fakeraid - sorry Now - one point I'd like to understand better - when you say for uruguay you don't mean the Ceibal team, right? (From OLPC perspective, if you talk about schoolservers in Uruguay, the Ceibal team is what I think of...).

Re: [Server-devel] Problems installing XS on new system for
Hi All, We have a disconnect about the target OS! Its my fault for not having tighter synch with tech leads in Uruguay. Sorry. I'm forking a private thread and I'll get it ironed out ASAP. Please hold the XS bring up until I can nail down the correct target XS. If Uruguay is on a non-standard OS we may have to build this app for more than one flavor of Linux :-( The fundamental web app design is still applicable so we can continue with the design of that. I'm just glad we caught it early. I'll come back as soon as I get it squared away. Thanks, Greg S *** Edublog != Ceibal.

Ok - you have cleared that up with the Ceibal team - they don't have some key pieces of our infrastructure in place (specifically, they are currently not running ejabberd, and it's unclear whether they are registering the laptops to the XO). Some of the identity stuff we are doing on the XS needs registration services running, and there's a small chance that might use ejabberd services...
