freezing DCON for insecure boot
Hello Mitch Scott, I have a laptop with a developer key, running an unsigned image with a few customizations for Turkey. They want a pretty custom logo and I succeeded in getting it to work in insecure mode, but it looks ugly because they see the kernel barfing diag messages on the console for a few seconds before the bootanim kicks in. Is there some forth-fu I could use to fix it? A modified olpc.fth file would be best for me as I don't have much confidence with forth and much time to implement and test it myself. Thanks. -- \___/ |___| Bernie Innocenti - http://www.codewiz.org/ \___\ CTO OLPC Europe - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Adding mpeg playback
Hello Andriani, our partners in Turkey are asking if the laptop can do mpeg playback. I said there are no technical reasons why it couldn't, but there are restrictive patent laws in the United States that do not let us ship mpeg software on the laptop. We bundle Ogg Theora as a replacement. They asked me if there would be problems for Turkey and I thaid that while I did not know their IP law, I hear it's not a problem in many European countries. Do you know better? And for the devel people: what should I do exactly to add mpeg support? Is installing gstreamer-ffmpeg from Livna enough? And how can we deploy such customizations in the future? Maybe we could add package installation support to the customization key? Or have as many build variants as required? -- \___/ |___| Bernie Innocenti - http://www.codewiz.org/ \___\ CTO OLPC Europe - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Turkey is going to be a big deployment, but as you say it seems they have no plans to participate in development with us at this time. We've had some good discussions around this recently as it has become very difficult to support Uruguay. This is why we separated out activities and content from the rest of the image. So that we CAN encourage countries to choose activities and content (and a few other things), but to try not to do any customization that requires their own image. This helps for most customizations I can think of, except things such as I want mpeg, which are very straightforward to do, but require changes to the (see my other post). Italy also asked us for a build with better Italian support. They know how to work with Pootle, and they actually have already done most of the work. But this work will certainly not make it for Update.1, and they can't wait for Update.2 to deploy. They asked me if they could create a custom build and reflash all laptops with it. I said it's certainly possible and not even that hard to do, but they will have to perform this work and support it on their own, because we certainly lack engineering resources at this time. I'm hopeful that what you are talking about is something that CAN go on the customization stick after the latest build has been installed. I just wanted to make sure you were up to speed with some of the more recent discussions we've had about customization. Yes, they just want the Istanbul logo on the boot animation, but the only XOs I have here for the demos are my development laptops and as such they are unsecured. I'm looking for a short term solution. Long term, this hack won't be needed. Once a country has agreed to send some developers to Cambridge to go through a build side by side with us, then they will have a better chance at successfully being able to support their own builds. We want to encourage them to get their changes into our builds so they won't have to manage their own streams forever. Yesterday I mentioned the possibility for Turkey's research institutions to collaborate with MIT and OLPC, but for now there are no contacts between the associations that supports us and universities. They said they could hire one programmer to handle the customizations that their government will request as a temporary solution. As we have often observed, it takes some time for a new country to digest the full potential of the international cooperation enabled by OLPC. Initially, they tend to see us as one of many laptop resellers. -- \___/ |___| Bernie Innocenti - http://www.codewiz.org/ \___\ CTO OLPC Europe - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Generating a new OS image takes 10 minutes of machine time and this is as simple as it can get. All the other steps our release procedures that create overhead assume some amount of testing is necessary before a new OS hits users. But if the only thing you change is translations, it doesn't matter whether you're doing it with a new OS image or through a separate language pack. The resulting system will in both cases be the old one plus these new strings. And this is what you have to retest in both cases. What we need is a fastpath in our procedures for this case. I think we had something adequate for security updates. Michael? sidenote Our friends here told me that we must urgently translate the word Pippy because apparently it has a very inappropriate meaning in Turkish :-) /sidenote I am currently working on a language-pack builder for deployers and testers, which would generate language packs for different releases (eg: Update-1, or Joyride), etc. This should separate the release process substantially from the translations, and deployers can add enhanced language packs for the deployed systems as the translations evolve. This would add yet another degree of implicit dependencies to our system. The way I see it is that we already have a very dangerous situation where Sugar and the activities can freely vary with respect to each other with no robust dependency tracking. If we also add translations to the equation, we're making it much worse. Then you get bug reports such as I don't get a string translated to Turkish, you'd have to ask the user: - what OS release? - what activity version? - what language pack? Unless we plan to switch to a true package manager, we can't modularize things too much. However, to make this work we also need to follow some kind of branching policy wrt the releases (eg: once Update-1 is released, bugfixes targetted for subsequent minor releases f'd uor Update-1 should be committed to the Update-1 branch only, while development for Update-2 should continue in the devel branch). This has to be done for _all_ activities (and of course, the components of Sugar as well). Yes, this is what is being done already for Sugar and many other packages hosted on dev.laptop.org (although there's no policy that mandates it). -- \___/ |___| Bernie Innocenti - http://www.codewiz.org/ \___\ CTO OLPC Europe - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

So it is really much better that the activities are now separate from the base code to help get this point across to the country. As a 'sales' type person, you need to convey that activities are built, tested, translated by the community. OLPC will not be qualifying or certifying them. The country needs to reserve time and resources in its own schedule to help ensure testing and translation of the activities that they want. And they can do this, because the activities are not tied to our release schedule. If we can separate translations in a similar fashion that seems like a good way to go. I had not thought about it in this way, but it makes sense. It is also close to what I've been saying to convey the idea that we are a large international effort. I often point out at the icons and say: See? These two come from developers from India and Brazil, while these are from a professor of Montreal. A few dumb questions that I've been forgetting to ask for weeks: - Is there anyone who maintains the activity packs to keep them up to date for new deployments? - Which pack should be used for demos and new deployments? I've been using the G1G1 pack for a while. - Will there be an official mechanism to update activities alongside the OS in the future? I've been using Bertf's update-activities.py, but it's of course for developers. 2 - Rolling a build takes a week, not 10 minutes. A build that is ready for release to the public, contains many steps: From check-ins, to packaging, to build creation, to testing, to the signing of the build, to getting a build properly into manufacturing... there are many steps and each step has many points of failure. Some of these we can eliminate over time through automation... but we aren't there yet. Both me and you have been intermixing the terms build and official release a bit too much. While the former really takes 10 minutes on my hardware, turning it into the latter requires all the additional work that you say. For small quantities such as in the Italian case, would it make sense to have a semi-official release that does not get preloaded in the factory, but is nevertheless signed by OLPC? -- \___/ |___| Bernie Innocenti - http://www.codewiz.org/ \___\ CTO OLPC Europe - http://www.laptop.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Internet wide chat
Ciao, here in Turkey they asked me how two kids or a kid and a parent may chat to each other between two households. Usually I get quite the opposite question :-) They understand there will also be privacy concerns to be addressed, but for now they are more interested in how feasible it would be from a technical standpoint. Competitors have been telling that our laptop cannot do such things and this must be disproved. They asked me explicitly for MSN, but I explained we are using the same protocol of Google Talk instead, and that's fine as well. Specifically, they want to kn - how could they make kids from Ankara and Istanbul chat together - how could a kid talk with his parents or teachers who are using a normal computer - what server infrastructure is needed locally, or if they could piggyback on our infrastructure. They are thinking of a use case of one million kids, which is not too distant in the future. - for large schools of 1000 students, they ask how the mesh view UI would scale. Are we switching to a search-based interface in when there are so many kids clustered in the same LAN? Note that this is not the same type of scalability of air protocols: for large schools they plan to break up the network using access points and a wired backbone. - classrooms in Turkey may apparently have up to 50 students. Do we have any results for such an environment? - They asked if it is possible to configure laptops to create logical partitions of the network by classroom - They asked if video chat is possible.

We need two things: a codec that we can encode and decode in real-time (the demo from 2006 used h.263) and a transport layer -- I think we have a UDP transport for Salut, but not for Gabble, so video chat would be on the local mesh only. So are we designing from scratch? I think it will be productive to take an existing application like Ekiga or Linphone and maybe just change the UI. Both support video RTP, although I'm not sure whether through plug-ins that users can download separately. Linphone works well: when we went to the Game Jam in Olin College, at some point I was bored so I installed it on the laptop and made a phone call to Italy. SJ may recall that I was walking around with the XO pressed to my ear like a huge mobile phone :-) Linphone also has a great advantage for us over Ekiga and Twinkle: it's designed around the good old engine-interface pattern that makes it easy for us to rewrite the UI. It already comes with two (although really crappy) UIs, plus a machine console for automated tests. I know these things because a few years ago I reused its guts for an embedded VOIP application, and the result was very good. It would be worth someone checking out the Theora team's latest optimizations, which might make Theora solve the codec problem. Even though we could ship that by default, it is important to also let users download the standard codecs to interoperate with other VOIP clients.

There's no law specifically disallowing the use of patented ideas. There's however law that grants the patent holder the right to ask you for a compensation if you use their idea. This is very different from copyright law, which is being enforced proactively and is punished with fines and in some cases even jail. In other words, a patent breach is not trouble between you and your country. It's between you and the patent holders. If they do not notice, or do notice but do not care to go after you, then you're totally fine. Legally and morally. And even if they _do_ ask you, patent law only allows patent holders a compensation proportional to the market opportunity involved in the specific breach.

Also, leaf functions tell us very little. memcpy() might be called from many different places to do different things. oprofile also supports stack traces, but for some reason I could never get them to work on the XO.

Re: OLPC/SL relationship
[dropping olpc-sysadmin@ from the cc list, updating the topic] Samuel Klein wrote: I was speaking of larger communication issues. Great. Can we resolve them by providing more and more regular (and more public!) information? Communication issues are rarely fixed by throwing pies. Announcing what OLPC is planning to do from time to time would be a first step in the right direction. Discussing these plans with the community on devel@ would be even more appreciated. Since when we started the G1G1 last year, OLPC became less and less inclined in discussing potentially embarrassing topics with the community in public lists. With many customers and deployments all over the world, there are understandable concerns about legal liability and potential impact on the public image. Well, I guess it's the necessary price one pays in order to grow a healthy and useful community around the project. You thought me that, remember? :-) Two week ago you said that a statement would be forthcoming about the relationship between Sugar Labs and OLPC. What do you expect in such a statement? What is the relationship in your words? I don't know what Ed had in mind, but I'd like to see more and more casual discussions of this on all sides. I keep meeting people who see the Sugar Labs effort as some kind of competitor to OLPC, or even a *fork*. And these are probably a small fraction who have been outspoken enough to say it. Our respective goals are distinct, but not necessarily incompatible. There's a lot of overlap that would make our long term relationship worthwhile in spite of the past. Walter Bender and Chuck Kane agreed to work together since before Sugar Labs was established. And many SL people also happen to be OLPC people, and vice-versa... so there is _already_ some kind of collaboration going on at some levels. What's needed at this point, IMHO, is a clear, open statement from OLPC that we're *really* committed to work together. Not merge, nor marry... but work together on the thing we both need: Sugar. Or maybe just say: NEVER, GET LOST!!! ;-) We should all be talking together, no relays necessary. Some of these planning updates are on my plate, and I will get back with more news tonight. What are Sugar Labs' plans for Fudcon? Providing more public information on all sides will help everone, more than the tastiest food fight.

It seems social interactions naturally drive people into choosing the narrowest possible audience when presented with multiple possibilities. *Especially* for controversial or strategic proposals; those where consensus isn't immediately clear. When Red Hat was trying to push all their internal development traffic out to the Fedora community, dwmw2 used to reply: I will not answer this message until it's posted on a public list. Yeah, let's encourage an attitude of violence!!! :-) OLPC is committed to having sessions specifically about the XO at XOCamp the three days after FUDCon so that we can focus on shared goals and components during it (and so that we can have wrap-up / overview sessions for people working on XO planning that builds on whatever comes out of FUDCon collaborations).I hope we can work out how to combine community infrastructure tracks of the two (and share resources to bring in community members from around the world who really need to build stronger ties with one another so that they can go back to assuming good faith on lists such as this one!). Let's get started from a wiki page we could edit jointly, maybe? The FUDcon is a self-organizing event, so they have no defined schedule until the day of the conference.

It really makes better sense to me to not squeeze bug hints into that first line at all, but instead include them in a later line of the commit. Dropping the leading Closes: makes it harder to rely on for automated bug closing. You might not care about that, but I must say that I find that mechanism pretty cool on Debian. If the Closes: line is going to be part of the long description, then I totally agree we should use it.

You mean that you agree with my proposal of having SL _optional_ or you mean that it must never be there? Imagine a future fork of Sugarlabs. Let's call it Suguntu to hint at where I am going with this. Suguntu has their own bug tracking system, and some Sugarlabs developers gets hired to work on both systems in parallel. In the beginning Suguntu acts as downstram to Sugarlabs, but over time some parts of Sugar then gets primarily maintained at Suguntu so some changelog entries close Suguntu bugreports and not Sugarlabs ones. I'd say it makes sense to allow SL as a hint, but just have it be optional so that for packages only maintained upstream at Sugarlabs there is no need to add it to eah and eery bug hint. I meant it should have been optional, but if we switch to using the Closes: header in the body, where we have no size constraints, then we could has well use the prefix consistently. -- // Bernie Innocenti - http://www.codewiz.org/ \X/ Sugar Labs - http://www.sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

One important note WRT 'Closes'... Code hits git way earlier than it hits the package. So in most projects where I work, people will put in the commit msg a bugnumber, meaning that it's _related_ to that bug. To say it 'closes' the bug denotes a confidence I rarely have when working with the SCM. Well, it's customary to introduce an additional state where the bug is fixed in the developer's intentions, but not yet QA'd: NEW - ASSIGNED - FIXED - CLOSED However, I'm not advocating for this just yet. Turn our quality knob up too much while our codebase is still a little immature and needs to change rapidly might even be counter-productive (i.e. project takes longer to reach stability). What's interesting about a Closes: (or Fixes:) tag, is that it could be used to automatically close the bug in trac from the post commit hook, thus saving some precious time to our developers. Once it's tested, and everyone's happy, the new release gets packaged, and we can say - with more confidence - that it closes some bugs. For example I have done series of 100+ patches related to one bug. None of them closed it, but once the new (major) release was ready, the package changelog did say Closes: #123. What's good for packaging... is good for packaging! Right, but who prepares the package changelog? If we're going to come up with something like the detailed Changelog that GNU coding practices demand, it's a lot of burden for very little value. The humanized release notes that Simon prepares, with reference to important bugs and new features, is ideal. A simple query in trac should be enough to find out what bugs were fixed between 0.42.1 and 0.42.2 if we care to add and maintain a target milestone field. -- // Bernie Innocenti - http://www.codewiz.org/ \X/ Sugar Labs - http://www.sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Mature GUIs have a common pattern to avoid too much graphical flickering on possibly rapid state transitions, such as setting a busy pointer or disabling buttons while some operation is in progress. I don't know if it has a name, but the algorithm is exactly the same for de-bouncing mechanical keys: you propagate the event only after the state has settled for a certain amount of time.

AFAIK, the bulk of the problem with multicasts over 802.11s (and not all wi-fi networks) is that those must be propagated at the slowest possible link speed in order to reach all nodes.

The only oddity I've seen is that libertas still has some reliability problems when automatic power management is switched on. Libertas' PM always has been a real PITA. I heard plenty of good kernel hackers swear between their teeth because of it. Marcelo would often swear aloud too :-) Today I promised to work on a cleaner patch for the main outstanding PM issue (http://dev.laptop.org/ticket/9967), but there is certainly something else going on. For instance, we seem to loose association for no good reason. After a few suspend/wakeup cycles, I even managed to make the Libertas disappear from the USB bus! In fact, this might not even be a 2.6.31 regression. To my (somewhat fuzzy) memory, automatic power management always has been disabled in OLPC's official builds due to similar reliability issues. At some point we may choose to give up trying to make libertas behave and keep the power management feature disabled for good. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

NetworkManager from fedora-updates-testing broken on F11-XO1
We didn't collect the logs in the field, but in /var/log/messages we found an assertion failure from NM which was more or less like driver ! = NULL, just after logging something about the OLPC mesh device. Wireless wasn't working at all afterwards. The broken package is NetworkManager-0.7.2.995-1.git20100202.fc11 . Reverting to a previous version cured the issue for us. Let me know if this is a known problem or if you need more help tracking it down.

Sugar 0.88 in F11-XO1
From today's #sugar-meeting: erikos bernie: I think a big problem to recruit 0.88 testers, is that there are no xo images erikos bernie: scratch builds, like tomeu said, sounds good erikos bernie: and then create a repo erikos bernie: maybe mtd is interested in that, too Ok, I'll create some custom F11-XO1 builds with the latest Sugar packages retrofitted for testing purposes. Who would like to help me out? Here's an initial draft: == Packages == Setup a yum repository with 0.88 packages backported to Fedora 11 (built in Koji with --scratch or inside an F11 chroot, whichever is easiest). It shouldn't require too much time, but it would be great if Fedora packages could offload this work from me and make the result available on people.sugarlabs.org in the form of a yum repo. Any volunteers? == OLPC OS Builds == Setup an olpc-os-builder environment to fetch Sugar from the above repo. I could easily do this at Paraguay Educa, but bandwidth to download the resulting builds is very limited here, and downloading images of over 500MB from my public_html folder is going to be painfully slow from the Internet. Perhaps I could duplicate the build harness on one of our buildbot slaves (in Italy) or a new VM on Treehouse. I doubt we can make olpc-os-builder work on Sunjammer, as it's quite Fedora specific. == Testing team == Test these builds with real kids. We have many kids with XO-1's in the nearby town of Caacupe, but school starts tomorrow and we cannot disrupt their regular classes too much. I think I could give an extra laptop to a small number of smart and motivated volunteers to test Sugar 0.88 side by side with 0.82 and 0.84 running on their regular XO. I've already identified a group of kids with a hacker attitude who would be perfect for the job. Educators tell me there are even a few kids who taught themselves to use the shell. Small teams of testers from other deployments would also be welcome, of course. == Collecting Feedback == Since Caacupe is 1hr away from the office, we'll teach our young testers to communicate with the IRC activity and/or through email. Getting them directly on #sugar may be problematic, but I don't want to send our testers to a /dev/null place where nobody would answer their questions. The best business practice to overcome language, cultural and age barriers would be to interpose support engineers. But the open source model requires a tighter feedback loop between users and developers. I don't speak much Spanish myself, so I'm counting on other community members to help out. As we're dealing with young people with little computing experience, we'll have to be tolerant and responsible. Hopefully, the increased confusion in #sugar will not bother technical members of our community too much. == Filing bugs == I'll try to file meaningful Trac tickets for our testers, possibly with logs and a pre-analysis. While our kids might not be able to report bugs on their own, Paraguay Educa has a few field technicians who could learn to do it. == Future opportunity: Fedora 12 == Optionally, try to upgrade to F12 or even F13. This would potentially introduce new distro bugs as well as the Sugar bugs. The benefit would be that we'd be working closer to upstream, but perhaps we'd be better off leaving the bulk of the distro hacking work to OLPC so we can focus our resources on testing only Sugar. == Future opportunity II: Usability testing == The Design Team often expressed the need to test proposed UI patches in the field. This is now possible to a certain extent, although with a limited number of testers. I could act as a dumb proxy: send me patches along with the feedback forms that you'd like the users to fill-in, or something like that. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
