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.

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

Re: freezing DCON for insecure boot
Bernie, It is really, really important that we don't encourage countries to have their own images if they are not developers participating in active development of our code base. 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. 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. 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. Scott and Michael will be able to go into the details of the customization process (if you don't know them). Thanks for your thoughts and understanding.

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.

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.

Re: New Planning Thoughts draft.
In my experience running QA teams and releases for commercial projects, small fast releases require (or imply) quite a bit of focused process and really good automation on the testing side. Also, after other discussions on this list, it seems like there are two other items that drive 'major release' twice a year and a few bug fix releases in between: 1 - Our target users (mostly schools) will not be upgrading often, and many will require weeks or months of their own testing before they do upgrade thousands of computers. 2 - From a support perspective, this audience will probably require that we support a major release for an entire school year. If we offer too many releases during that time, we will not be able to keep up with the backward compatibility matrix of releases that have to work with other releases. If kids upgrade on their own, will they work with the older version that was installed on 90% of the other laptops, etc. I think if our product were aimed at developers or if it was a server-based product where we could control the releases and there were no backward compatibility problems, then it would be great to have many small, fast releases.

Even linux distro (Fedora at least,), doesn't actually do focused releases. Roughly, they set a timeframe and they get in everything which is ready by that date. This is very easy for a linux distribution. It would be harder on the Sugar codebase but still very much feasible, it's the same approach of GNOME releases.

Clipboard[PATCH]
This patch disables the frame from popping up when you copy an object to the
clipboard and instead pops up a notification icon in the bottom left hand
corner. It also adds the ability to add_notification() for future use to
place icons in any of the four corners.

Subject: [PATCH] Clipboard - disabled frame popup and enabled icon notification
When an object is added to the clipboard the frame no longer pops up but a pulsing notification icon is displayed in the bottom left corner.

Then we would only need one single multicast address and do the filtering on the ethernet ports (eg IP is port 0x0800). At the very least, the multicast address is 6 bytes and the ethernet port is 2 bytes. That's possible, yes -- although you won't get the device filtering it for you then. Error. Question upside down. Please don't top-post. It's possible to do as you say -- to use different ports for different activities (although I read 'UDP ports' where you actually said 'ethernet ports' so perhaps I misunderstood). The device firmware doesn't speak IPv6 or Legacy IP, however -- and we wouldn't want it to, even if we trusted it. So it wouldn't filter for only those ports you're interested in; it'll give you all packets for that address. You're not following: Ethernet ports are bytes 12-14 (2 bytes total) on _all_ ethernet frames. IP has nothing to do with this. Instead of looking at the first 6 bytes (destination mac) for a specific multicast address, the filter should be looking at bytes 12-14 for a specific ethernet port. Pol An ethernet frame may exist to the host, but what the firmware gets is the incoming 802.11 frame. Since the mac filter is used immediately after the blinding table filter, there is not an easy way to get this information. It would involve looking into the frame payload to find some bytes that are not in a fixed position. At the application level though, it is possible to multiplex one single multicast address with as many applications as you need, using an UDP port. This involves reengineering the middleware but it is a scalable solution. But sorry to insist that, if after the eighth address has been taken the host will respond to *every* multicast frame, then in this unlikely scenario, suspend would not be as effective and thatś it. I am afraid we are creating an issue out of nothing, possibly complicating matters later. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

This page is currently an orphan, so if someone could link to it from some other relevant pages, I'd be most grateful. I've since found a couple of other pages which are related: - http://wiki.laptop.org/go/Connectivity This page describes itself as part of the support FAQ, so maybe not suitable for extending with information for developers. - http://wiki.laptop.org/go/Network_Configurations This is much more similar, and has a cool diagram, but I'm not sure how the list there matches up with mine. In particular, it's not clear whether Access Point implies the presence or absence of a server, and my list doesn't contain the Mesh Portal Point. I also stumbled on this blog, which is about asynchronous communication/collaboration: http://www.nilshettich.com/olpcblog/ I think it might have some interesting ideas for us as we try to support long-term collaboration in addition to the real-time collaboration that Sugar supports today. -- Dafydd ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: freezing DCON for insecure boot

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. The Forth command dcon-freeze will freeze the screen immediately. The Forth command freeze will cause the dcon-freeze command to be executed at the next transition to a booted program. Either can be executed from inside olpc.fth The reason for the freeze command is so that screen animations showing the progress of bootloading sub-steps can be seen, but then the Linux black-screen text messages will be hidden.

This would be a great idea. Yes, Italian is an easy language to support for us, so it's just strings. Update.1 had an interestingly long string freeze an I guess Italian is not the only translation that suffered by it. Torello was also asking some time ago on the #sugar channel why his changes in Pootle did not yet show up in git master. I don't know if this was answered already. I also think some TamTam strings were missing due to musical jargon, but this is hardly a showstopper. I'll let Torello be more specific. Giulia and Torello, reading us on cc, may have an approximate idea of the dates involved. Scott (or Kim), do you have an idea how long it could take to roll this Update.1.1 once we have everything in place?

Re: New Planning Thoughts draft.
2008/4/18 Kim Quirk [EMAIL PROTECTED]: In my experience running QA teams and releases for commercial projects, small fast releases require (or imply) quite a bit of focused process and really good automation on the testing side. Excellent ideas, both, in any case. Also, after other discussions on this list, it seems like there are two other items that drive 'major release' twice a year and a few bug fix releases in between: 1 - Our target users (mostly schools) will not be upgrading often, and many will require weeks or months of their own testing before they do upgrade thousands of computers. That is one class of target users. There are several others, including developers, education researchers, and the wider public. Now that Sugar packages have been integrated into an imminent Ubuntu release, that wider public is quite wide indeed. 2 - From a support perspective, this audience will probably require that we support a major release for an entire school year. If we offer too many releases during that time, we will not be able to keep up with the backward compatibility matrix of releases that have to work with other releases. If kids upgrade on their own, will they work with the older version that was installed on 90% of the other laptops, etc. A division like Debian Stable, Unstable, and Testing would resolve that. Those who want the bleeding edge software will be on notice that they are part of the QA. We could still move bug fixes into Stable, and all other enhancements into Unstable (or whatever we choose to call them). Then schools would have the assurance that all students have the same basic suite of compatible software, able to run all of this year's interactive teaching materials. I think if our product were aimed at developers or if it was a server-based product where we could control the releases and there were no backward compatibility problems, then it would be great to have many small, fast releases. Kim I see no real reason why we can't have the best of both.

I think more, faster releases are a better approach. the testing effort grows much faster then the count of changes (with the need to test combinations of things) so frequent, small releases are easier to test.
