We are working on such through the journal, but have "been working on it" for too long to wait. An rsync based solution has been used in the past, and most of the infrastructure is in the laptop build now. A laptop is "registered" with a school server. This provides the laptop with globally defined names for it's presence and backup services (defined in /etc/idmgr.conf on the schoolserver), as well as creating an account on the school server. The username is the laptop's serial number, the password the UUID, and its public key is placed on the school server for future authentication. The user interface has a "register" command in the menu associated with the XO figure in the home screen which triggers the above process (with port 8080 on DNS name "schoolserver" in the local domain). It goes away once a laptop is registered. All that is missing for backup is a cron script on the laptop doing the rsync (I have examples, but the servers are down right now...), and a tweak of the schoolserver HTTP server to make the backups accessible. The result will be files that use names meaningless to the users, limiting any collaboration or sharing. But it will make disaster recovery possible! The correct way to do this is to work with the Journal to treat the laptop as a cache of a larger Journal datastore located on the Schoolserver (and beyond, "in the cloud"). Perhaps Ivan can detail his vision and we can get other people to help implement it. > 2. Is the active antenna the same as any wireless router working > as an access point?

You can use multiple conventional access points to provide a school wireless network, (the school server software http://wiki.laptop.org/go/ XS_Server_Software supports them on the wired LAN interface). We hope to make Active Antennas available through an online store sometime in the short term future and are working with a commercial vendor to make it happen.

Therefore an activity that cannot be re-coded to use ALSA should simply include OSS emulation modules. snd-pcm-oss is available on joyride-1550. If it is defective, it could be looked into. I've just tried it. It loads fine, /dev/dsp is present, reading from /dev/dsp turns on the mic LED, piping /dev/urandom to it generates noise. ALSA also includes an OSS wrapper library, libaoss, which can be used by an application.

They (I've gotta refrain from saying "we" here, my heart's there but I'm just someone so lucky his wife gave me a G1G1 for christmas) are positively, unavoidably in the content business. Without enough Activities in the built-in image to bootstrap experimentation, discovery, and creation it's just an appliance, not an educational tool. So they're delivering a very carefully managed set of built-in Activities, and that's content. Where things get exciting is the link, built into the Browse default start page shipped with the image, to http://wiki.laptop.org/go/Activities>. The stuff linked off that page certainly isn't OLPC-shipped content --- but that direct link ties it closer to the project than the normal breadth of the internet. Nothing worrisome will go into the image; it appears that the official OLPC team doesn't have the usual proportion of ... less than helpful folk. We can't censor the internet. There's reasonable grounds for being careful about activities on the page directly linked from the wired-in home of Browse, both in terms of the children and the media. It's not the image, but thanks to that direct link it is also not the breadth of the internet. I'm a chicken, I'll freely admit it.

Re: Violent games on the OLPC Activities page
Look, a big part of my heart is dead centered with those who want to entirely avoid any sort of pre-judgement of Activities at all. But I've got a question. What's the youngest target age OLPC is shooting for, for kids to get these lovely gizmos? http://wiki.laptop.net/go/Activities is _Special_. The first time they fire up Browse on their glorious new companion, lookie, there's a link that takes them straight there. That link is shipped with the OLPC image (unless G1G1s are different from real ones here?). And that implicity makes it a place whose content _appears_, no matter how we disclaim, to be a part of the OLPC "product offering". I'm really loathe to argue that such a page is an appropriate place to press for my non-currently-mainstream, not-politically-correct views to be expressed. It wouldn't take too much idiotic media hoo-haa to inflict a taint on the project. So I'm deliberately taking a position here that isn't really where my heart lies, because I fear that in the constraints of the real world as [largely, in the US, where OLPC comes from] the media creates and defines it, this is sadly a wise place to forget the personal values and yield partially to a more politically-correct posture. I'm not retracting anything I said before, I'm glad this discussion has evolved towards ideas for practical tagging and classification and controlled presentation. And for sure, let 'em at the internet unsupervised and they get absolutely whatever they feel like, P.C. or not. But http://wiki.laptop.org/go/Activities is in practice, or at least in perception, part of the product since Browse always starts with a direct link there.

Suggestion for Terms of Use for content
I immensely admire the Scratch website as a space for collaboration for kids and adults. I suggest OLPC seriously consider adopting these same terms of use. Scratch Terms of Use http://scratch.mit.edu/terms As part of the Scratch community, you are sharing projects and ideas with people: • from many different countries and cultures • of all ages (from young children to teens and grandparents) • with all levels of experience We need your help to make this community a supportive place for every member. Here's how you can help: Be respectful. When sharing projects, remember that people of many different ages and backgrounds will see your creations. Offer constructive comments. Instead of just criticizing a project, say what you like about it and offer suggestions on how to make it better. Give credit. Feel free to make modified versions of other people's projects - just make sure to give them credit. One place to give credit is in your Project Notes. Help keep the site safe. If you feel others would find a project mean, insulting, too violent, or otherwise inappropriate, click the link from that page: "Flag as inappropriate." (The Scratch team will review, and may remove any project or comments.) --- I think it would be great for OLPC to put together a team to periodically review content tagged as inappropriate. This group should include teachers and women (who could be teachers :) not be solely composed of male software developers or pseudo-developers like myself. Perhaps it would be good to set up a site like www.xohacker.org where people could post their free clones of Grand Theft Auto or Leisure Suit Larry. This would give people the freedom to do what they want and maintain a safe environment for kids w/in the OLPC activities pages. Frankly, I myself like violent games but I respect that they bother a lot of people, particularly teachers and parents I work w/. I will try to contact John Maloney of the Scratch team and find out what particular procedures they have for reviewing content. BTW, I really like ScratchR community site and think it is a great option for hosting the activities. http://scratch.mit.edu/scratchr I hope this doesn't start another rewar :) -- Bryan W.

Re: Violent games on the OLPC Activities page
Beg Disclaimer Jeffrey, I'm replying to your message because it was the latest one in the thread when I retrieved my 120 OLPC mailing list message today (actually, that comes from several OLPC mailing lists, but devel seems to have the most traffic on any given day). So, what I say here is not a reply to you personally. End Disclaimer I think the direction this thread is taking is completely the wrong way to go about things. OLPC should be in the business of delivering a platform and productivity tools (e.g., word processor, paint program, etc.). It should NOT be in the business of distributing content. ANY content. Tools to build content, definitely (EToys, pyGames, et al.). But NOT the content itself. If you folks think this little dust-up over violent games is a big deal, just wait until the creationists, the scientologists and the new-Nazis discover the XO. If you take a look at some of the stuff on YouTube criticizing the very purpose and legitimacy of the OLPC project itself, you will know that we are going to have enough trouble just defending the platform and the tools. $200 USD can by a lot of rice for starving children and there is no shortage of people out there right now trying to brand the OLPC project as another elitist wet dream. My advice to OLPC is to get out of the content business in any way, shape or form as quickly as your little green computer can carry you. You don't have to worry about the XO not having enough educational content. Many people not affiliated with OLPC will be developing content for this platform. Then, let the recipients of the machines make the content decisions using their own, local standards.

Re: Why can't i access /dev/dsp or /dev/snd on my XO
How about just reenabling OSS emulation? It's included in alsa, so it should be no problem, maybe it's just a case of modifying modprobe.conf. I second Victor's suggestion for the csound api, though. I wonder if there is a major impact on performance by using it? Cheers, Andrés On Jan 18, 2008 5:24 PM, victor <[EMAIL PROTECTED]> wrote: > What exactly is the problem with the alsa driver?

Choosing a correct working-dir for upgrade-server
When inetd runs upgrade-server/upserv.py, it does so with in the working dir /. Since the upgrade-server's python modules are not installed in PYTHONPATH, this choice of working-dir interferes with the module loading that occurs when re-running python inside fakeroot. Hardcoding the correct choice of working-dir fixes the observed failure of the upgrade-server's 'on-demand build download' feature; however, it's probably worth fixing this for real by either: a) packaging upgrade-server so that it properly installs its modules in PYTHONPATH or b) calculating an appropriate working dir at run time based on a command-line argument, environment variable, or based on the location of the python script being executed. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Why can't i access /dev/dsp or /dev/snd on my XO
What exactly is the problem with the alsa driver? Csound works OK with it. Replacing it with OSS will require us to write a new IO module for Csound. Without Csound, audio and music on the XO will have to be completely re-written. IMHO, developers wanting to use audio on the XO should ideally use Csound and its Python API. That's why it's there. As far as I am concerned, having developed audio apps for Linux for several years, Alsa is much better and more reliable than OSS.

Fwd: Activity search/browse on wiki (was violent activities)
I'm rescuing this concrete suggestion, since most people probably have the 'violent activities' thread in their killfile by now. (Sorry about that, I'm as guilty as any of adding personal anecdotes instead of productive contributions). The problem: have a community-maintained list of activities that is viewable and/or searchable in different cross-sections based on need. It should integrate well with the wiki, so probably the first place to look is for mediawiki extensions. There are several that might help: 1. You could do an evil hack by combining page inclusion with the well-tested PageFunctions (for variables declared at the top of an including page) and ParserFunctions (for using in templates that can hide themselves depending on the variable values). This would involve hacktastic, hard-to-maintain work for each new slice view you wanted to implement. However, if you keep things simple (all, unproblematic, core), this would not be too hard, and populating it could be done by anyone able to copy and edit wiki templates. 2. The WikiDB extension [1] appears to be a beta version of precisely what is wanted here. From quickly browsing its homesite, it appears to be working, but possibly too buggy to slap onto a wiki as large as the OLPC one. Significantly, it does not guarantee that the databases it creates will stay in sync under rarer operations (restoring deleted pages...), nor does it appear at first to have a way to regenerate its databases if they do get hosed. Go have a look if you're interested and tell us what you think. 3. Semantic mediawiki is a heavyweight replacement version of Mediawiki with some tools that, while they are not precisely what we want, would work for this issue. The focus is more on browse than on preconstructed views integrated with a wiki page - I think that for us the latter would probably be better. Probably overkill.

OFW & hello.elf
Hi It appears that the sample "hello world" program [1] provided with OFW is not working on latest stable revision. At least, it didn't work for my G1G1 unit with Q2D07. When running it with "boot" command, I just get: ok boot disk:\hello.elf Boot device: /usb/disk:\hello.elf Arguments: [ nothing printed, no prompt ] It works fine when using latest SVN in qemu / pc-serial build, though. I find this really strange, because I got reports [2] that ELF images are indeed working on XO, although I don't know which hardware/firmware versions. Also, I'm not sure if this is a loading problem with ELF format or with the OFW callback interface, since Linux images seem to differ in both things with hello.elf. Perhaps someone else can try hello.elf and see if it works?

If you don't load the firmware within 5 seconds of the boot2 code starting up, the thing loads its own firmware from the internal flash. Yes, it's horrid. It doesn't even preserve the boot2 version, because we did some stupid hack to preserve that in the _driver_ rather than keeping it internal, so when we send the CMD_802_11_RESET command to kick the device back into boot2, we get 'device firmware changed' from the kernel and it appears as a completely new device...

You could do an evil hack using the well-tested PageFunctions (for variables declared at the top of an including page) and ParserFunctions (for using in templates that can hide themselves depending on the variable values). This would involve significant, hard-to-maintain work for each new slice view you wanted to implement. However, if all views were just a series of subsets of the 'all' view (all, unproblematic, core), this would not be too hard, and populating it could be done by anyone able to copy and edit wiki templates. 2. The WikiDB extension [1] appears to be precisely, exactly what is wanted here. From quickly browsing its homesite, it appears to be working, but possibly too buggy to slap onto a wiki as large as the OLPC one.

We're not really arguing here, we agree. Everyone agrees that wireless +mesh should start automatically by default after bootup. What David (and I in like 3 mails yesterday in this thread already) had proposed was that the XO firmware should disable the radio _until_Linux_loads_ and the driver tells it to enable the radio. When Linux loads, the driver (or NetworkManager, or whatever) starts the radio. That way, the user at least has a change to at some point say "no, don't turn on the radio by default" if they want to. _Nothing_ would change for users who do not want/care/need to touch the radio in this scenario, everything would continue to work as it currently does. I'm not sure where you get the idea that we're saying it should all be in airplane mode all the time unless the child explicitly turns the radio on. We're saying exactly the opposite of that.

Yes. The active antennas firmware would need to be slightly altered to start on firmware boot, but the normal XO firmware should certainly be radio-off-until-driver-enabled (by setting IFF_UP or device open).

I don't think so. If people feel so strong about this they can always block firmware loading.

Re: Violent games on the OLPC Activities page
It seems that there are three ideas that have so far emerged form this discussion: tags, "favorites" lists, and need for a better back end than the wiki currently supplies to support search, sort, etc. As SJ pointed out very early on in the thread, there is a page in the wiki (http://wiki.laptop.org/go/Activity_guidelines) that is dedicated to the definition of criteria by which activities can be assessed. Please help us expand/refine the list and perhaps cross reference the list with existing tag systems. It'd be great to generate some pages in the Activities page hierarchy that include slices through the activity list that are appropriate to different contexts, e.g., my favorites, etc. Finally, any suggestions about how to extent, augment, or replace Media Wiki with tools to make these sorts of things easier for the community to manage would be appreciated. -walter ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

No one is coming even remotely close to saying that these kind of potentially offensive or harmful activities/content should be there by default, what is being said is we shouldn't pretend it doesn't exist. If someone wants it, it will be right there in the list, with a nice little description that makes no false projections as to what is contained. It comes down to what OLPC's job in this is. Are we simply chronicling what content is out there, or are we actively pushing certain content and curtailing others. I think both have a place, and a wiki page with links to a small collection of high-quality educational content would be a great addition to the wiki.

Unless I'm completely misreading you, you are arguing on the basis of your experience as a soldier that Children need to be exposed to violence lest their naivety be taken advantage of by monsters. This is a valid point of view. I let my own children play the Harry Potter games and Starcraft etc. etc. (and yes, when they are older Quake or whatever other waste of GPU cycles Id has come up with by then) to their heart's content because of that very reason. BUT The thing which I am trying to point out is that on the continent on which I live children are _already_ on the receiving end of violence with the result that their needs are different to the needs of my children. Or to put it yet another way: South Africa is still deeply fractured along racial and economic lines. Less than ten minutes from my children's school is a predominantly poor community. The children in this community have daily experiences of drive-by shootings, sexual abuse, rampant crystal meth and alcohol addiction, gang warfare and other such pleasantly formative experiences. Now in my children's school, there are a small amount of children from that community. With a result, that I can guarantee you that if ANY parent at my kid's school were to start arguing that the school should install Doom on the media center's computers that I would oppose them in any way I can. Sure - if we were to make these kinds of decisions on the basis of a majority then _clearly_ there are more kids at the school who would learn from Doom than kids who would be traumatized by Doom.

In any case, they certainly won't be forced to install and run it. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Mr. van Gelder, I respectfully request that you read my message, over and over if necessary, until you understand the severity of your egregious and insulting error. Then apologize, not just to me, but to the others on this list who have had it far worse, and are even more fed up than I am with those whose ignorance and lack of imagination causes them such pain. The rest of you, no spoilers. He has to make this discovery himself for it to take.

There is a strong tendency for experienced teachers to reject anything new, just as in every other human endeavor. And we need far more than divulgation, we need entrainment. Teachers need to discover discovery themselves before we can divulgate the rest to them.

It is a hard balance to strike. Socratic teaching was devised for a one-on-one situation by a master. It was never meant for the classroom. I recommend looking at Caleb Gattegno's work on discovery using Cuisenaire rods. But you can't improvise this stuff in the clasroom until you have mastered what others have discovered how to do. > I've made constructivism work in the classroom a few times, too, and it is > great.

I believe that the actual idea is to get children so interested in discovery that they will carry it forward, even on your off days. But yes, you still have to know your material, the children's capabilities, the likely paths of discovery, and the likely impediments to discovery backwards and forwards. However, as Maria Montessori amply demonstrated (and her followers have almost entirely forgotten) we know very little about what children are really capable of. We need a serious set of research programs, and a means of sharing the resulting knowledge. That means that we need to get a lot of teachers to catch the discovery bug, so that they will join in collaborative discovery of collaborative discovery itself. > Luckily, we here do not actually have control of any schools.

Yes, indeed, control is not what we need, and certainly not what I want. I want teachers and parents, as well as children, to have the advantages of discovery. > And there's another constituency besides teachers and students: > researchers/administrators/bureaucrats.

Researchers have done excellent work that is utterly dismissed by administrators, teachers, and governments in disasters such as New Math and the continuing war between the linguistics profession and the language teaching profession (local and foreign language, both). Even the controversy between Whole Word and Phonics, which is utter nonsense. It is impossible to read English without using both methods, and in addition referring to a dictionary from time to time. I defy anybody to figure out, unaided, the pronunciation of the astronomical term "aphelion". (I have already given you a major clue, so you can't count yourselves. But I do congratulate you if you get it from just that clue.) Phonics can't handle "once", the 'ough' words, and a multitude of others, and Whole Word can't hope to ha
How to? School server implementation
Hello everyone, I have some general questions regarding school server implementation. I was hoping someone with development experience or someone with pilot experience might have some knowledge on this matter. I am working to implement the OLPC pilot program in Nepal, and would really appreciate some feedback on these questions 1. What is the best way to publish/collaborate/save etc with school server? Meaning what is the best way for kids to save, retrieve, and share files through a school server? I know moodle is an option , but is there anything else? Has anyone tried a different way to do so? something like web folders maybe ? 2. Is the active antenna the same as any wireless router working as an access point? I should be able to use the same networking features if i use a wireless router right? 3. What is the range of the antenna by itself? (discarding the fact that the XO's can relay) best, -sulo ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

The fundamental flaw in this line of reasoning Jeffrey... and this is a flaw which any sophomore would have been able to spot in the days when they still taught logic and critical reasoning skills at American universities is this: -> Putting violent arcade games in an educational resource violates the right to spiritual and emotional recovery for nations that are in the process of recovering from war. -> Making lists of whatever entertainment resources you wish _OFF-SITE_ does not violate anyone's freedom of speech nor their right to choose whatever type of drivel they wish to waste their time on.
