Whoever needs more can easily edit /etc/inittab. Shall I write you a tty-watcher program in assembly code? This really shouldn't cost much memory. Even with glibc, I doubt the dirty memory was all that much. BTW, I'm serious about the assembly code. Well, if it's just for fun... but I think the Python developers would not appreciate it :-) Seriously, before we start coding solutions, let's first reach consensus with the security team on how we should handle login. Otherwise we risk wasting effort. I quite like this Press ESC twice for shell solution. Reminds of the FidoNet era, if you're old enough to know what I'm talking about. Good point, but if we left just that in place, we'd have to ask people to use the ugly text console more often, where the keyboard works partially and there's no cut paste. It's not ugly if you ship the nice 15x30 font I made. Where is it? Does it include a decent amount of unicode glyphs? sun12x22 has too few of these, so it doesn't even support many European languages. Cut-and-paste can be fixed, with the difficulty depending on how perfect you want it. One can run gpm. This can be started when a user logs in on the console. One could even write something to feed that into the X clipboard and back. Yes, theoretically. But we don't ship gpm and we don't want to put much more effort on improving the console environment that only UNIX die hards like me and you enjoy using when we still have a journal that eats files and a mouse cursor that flashes when you render below it.

Re: Circumventing kernel signing
Mitch Bradley wrote: At some point, when these fairly obvious loopholes that we have known about since forever are closed, we plan to change the key so new machines will only run the more secure OS versions. Old machines will continue to be vulnerable until they are upgraded to new firmware with the new key, and some old machine may always be vulnerable. Meanwhile, I reiterate my earlier claim that a no-modules kernel will be easier to secure. Even if you require signed modules, the extra complexity creates attack opportunities. Each additional door is a ingress opportunity. Anything you build into the kernel similarly increases attack opportunity. For example, an IPv6 and IPv4 kernel and the networking infrastructure. You might load IPv6 to support a 6bone network, and load net; then find there's an IPv4 stack bug and you can kill iptables and get a kernel level exploit. Not vulnerable, of course, since you're running IPv6 and not IPv4. Of course, with everything built in, you have IPv6 and IPv4 all the time, and a worm can use IPv6 to spread to its nearest neighbor and then crawl out from there even if there's no real routing. This is an absurd claim, I know (though Linux has had an IPv4 flaw, and OpenBSD has had an IPv6 remote exploit); but claiming module loading itself provides an attack opportunity is just as absurd if not moreso when dealing with signed modules. Your most likely attack opportunity is by far a flawed hashing algorithm or implementation; it's likely the same algorithm as in OFW, possibly implemented off the same reference code, and the attack for it (generating a collision by tweaking a modified binary) is going to work either way. So in short, yes, even with signed modules you still have module loading itself to wonder about; but the potential attack opportunity here is as absurdly small as finding a way to alter PGP signed messages (which was done once; implementation flaw in how GPG checks signatures, allowing an attacker to append unsigned content to a signed message while GPG reported the whole message as signed).

Printing and the XO
apologies for not maintaining threading, but I've just subscribed on Wed Jan 2 16:43:39 EST 2008 Peter Krenesky said: nice overview of printing Configuration - XO The number of printers, the models, and their locations will be unknown. It may be 1 printer per school, or many depending on the country or region. Adding or selecting a printer needs to be simple. Autoconfiguration is the best case scenario but some manual configuration is still needed. A GUI is required for all of this. The presence service may be a way to discover printers and configuration information. IE. the advertisement includes the configuration to be added to /etc/cups/printers.conf A printer would really only be configured, once, at the server. Some unanswered questions are: * What does this GUI look like. * Where is it located within sugar. Within the configure activity? in the past when I have needed to support printing from many machines and have not wanted to have to change them all when swapping out a printer for a different model I have had very good success with the approach of just telling all the machines that they have a postscript printer and let the server do all the printer-specific conversions. if you really wanted to get fancy, let the server accept HTML as well as postscript to avoid the work on the laptop to convert things (although I suspect that the conversion of HTML to postscript is trivial enough to not be a big deal anyway) this would be the first piece, because you really don't want to have to touch every laptop when you swap out one printer for another one. at this point the remaining problem becomes picking which printer to use. For this you can get a _lot_ of mileage out of simply defining a default print queue (lp or printer, just pick something) and have the laptops use that queue on the school server they are registered to by default. after that a simple dialog that lets you pick a different queue or a different server will cover almost everything else. as for CUPS, I understand that it's the current fad for printing, but I question if it's the right thing to use for resource constrained machines like the XO. CUPS wants to have each machine load the printer driver and do the rendering for the printer before sending it to the server. the servers are almost certainly going to have more resources available then the laptops, and so there's a good argument to be made that the laptops should just send the unconverted print image to the server and let the server render it for whatever printer is attached. the drawback to taking this approach is that it is harder to take advantage of all the features of the printer (paper sizes, trays, staplers, hole punches, etc), but while corporate users will miss these features, the vast majority of printers don't have such features and most people really don't care about them (they just want the image to show up on paper). the one feature that is worth going to some effort to produce is a way to print double-sided if the printer supports it, but it should be possible to do this in a way that won't interfere with normal printing.

2. Existing website, if any : http://wiki.laptop.org/go/TalknType
3. One-line description : A spelling game using speech synthesis,
in the style of the SpeakSpell toy.
4. Longer description :
* Currently only a terminal
python program - needs sugarising...
* User opens the activity,
and is presented with a skill level (1 to 4).
* The activity speaks, using
the eSpeak Speech Synthesis software, which will soon be included in
OLPC builds.
* The activity asks the user
to spell a word from the dictionary (one of four, based on the skill
level).
* As the user types each
letter, the activity reads the letters out loud.
* When the user presses Enter,
the activity reads the entered letters as a word.
* The activity compares the
entered letters with the real word, and informs the user whether the
word was spelt correctly or not.
* Another random word is
offered for the user, etc, etc.
* In future, a more
collaborative version will allow you to test your spelling against a
friend, and compete on points.
* This activity would lend
itself well to Pootle translations, although multiple dictionary files
would be required.

6. Committer list
Please list the maintainer (lead developer) as the first entry. Only list
developers who need to be given accounts so that they can commit to your
project's code repository, or push their own. There is no need to list
non-committer developers.

7. Preferred development model
[X] Central tree. Every developer can push his changes directly to the
project's git tree. This is the standard model that will be familiar to
CVS and Subversion users, and that tends to work well for most projects.
[ ] Maintainer-owned tree. Every developer creates his own git tree, or
multiple git trees. He periodically asks the maintainer to look at one
or more of these trees, and merge changes into the maintainer-owned,
main tree. This is the model used by the Linux kernel, and is
well-suited to projects wishing to maintain a tighter control on code
entering the main tree.
If you choose the maintainer-owned tree model, but wish to set up some
shared trees where all of your project's committers can commit directly,
as might be the case with a discussion tree, or a tree for an individual
feature, you may send us such a request by e-mail, and we will set up the
tree for you.
8. Set up a project mailing list:
[ ] Yes, named after our project name
[ ] Yes, named __
[X] No
When your project is just getting off the ground, we suggest you eschew
a separate mailing list and instead keep discussion about your project
on the main OLPC development list. This will give you more input and
potentially attract more developers to your project; when the volume of
messages related to your project reaches some critical mass, we can
trivially create a separate mailing list for you.
If you need multiple lists, let us know. We discourage having many
mailing lists for smaller projects, as this tends to
stunt the growth of your project community. You can always add more lists
later.
9. Commit notifications
[ ] Notification of commits to the main tree should be e-mailed to the list
we chose to create above
[ ] A separate mailing list, projectname-git, should be created for commit
notifications
[X] No commit notifications, please
10. Shell accounts
As a general rule, we don't provide shell accounts to developers unless
there's a demonstrated need. If you have one, please explain here, and
list the usernames of the committers above needing shell access.
11. Translation
[X] Set up the laptop.org Pootle server to allow translation
commits to be made
[ ] Translation arrangements have already been made at ___

RE: Printing and the XO
Hi Peter, Which teachers or schools have been asking for printing support? If we can add some documentation on that to the Wiki it will help a lot. It makes sense that schools would want printing and CUPS is a robust tool in my experience. Real world user cases will help determine how much effort is needed on the configuration/moderation fronts. They can also help validate if copying files to a USB drive is a viable alternative. My guess is schools want a printer if they can afford one. Let us know what feedback shows it's a priority for existing XO deployments and let's find out what printers they have and how they want to use them.

Re: Sugar UI design and Tux Paint
Agreed. I said, 'sometimes'. I think that it is better to stay non-modal if possible. (For the last of your cases, changes to activity structure, eg email settings or ftp server or something, an autosaving dropdown/autocomplete list of previously-used settings is a way to provide undo without overloading the 'undo' command. Invasive changes to the interface should not be opaque - there should be some visible way to realize what is going on, or even a cue to changing the preferences back. And as for nontrivial computation, it is at least theoretically possible to save the settings in real time but apply them later. So I think that the modal-necessary cases still exist, but are rare exceptions.) Indeed; this is why we have thus far implemented only the non-modal version. Particular instances have come up within Sugar that will require modal dialogs, though. Certainly the HIG will encourage non-modal ones when possible. I only provided one or two, but I imagine that most activities will use them all. Read my proposal for Handheld mode in Browse for a more complete understanding of the type of interface I was envisioning: http://wiki.laptop.org/go/Browse#Handheld_Mode. In this paradigm, the buttons retain their pairings when needed, and they can have both instant and hold states (as modifiers which reveal an overlay menu which can be navigated via the directional buttons). A lot of good ideas there, of course. I think we can come to a good compromise between my issues (more across-activity-consistency and complete-access, including sugar) and yours (in-activity applicability and usability). One basic idea of yours is to double the buttons by providing both press functionality and hold functionality (with hold often a context menu related to press). That is obviously applicable in my scheme too. With this in mind, here's a look at your browse scheme vs. mine applied to browsing. As a note, one thought behind the hold state for the buttons was that it offers additional functionality on top of the basic set of actions which is secondary, and therefore not necessary for the use of the activity in simple form. I'd like to keep this idea, never requiring the hold states to be used unless the child wants extra power within handheld mode. up/down/left/right: you scroll with up/down and select links with left/right; I select links with both. But notice that the two are not actually as seperate as it would appear. Selecting links can cause scrolling and vice versa. So in my scheme, a click selects links. If that is a small distance vertically, then a hold would be ONE page down/up; if it is a larger distance (maximum one page), then a hold would be continuous finer scrolling. (side to side would wrap, and a hold would scroll) I'm not sure I'm properly envisioning what you mean here. There seem to be a number of ways to move about the page (scroll, page, jump-by-link), and there doesn't seem to be a predictable mapping of button to function in this model. If I want to scroll down a few pixels little to fit an image on screen, I have to hope that the links are far apart. If I want to jump through a bunch of links in a long list quickly, I can't, because the hold state of the links button is a paging function, rather than an autorepeat on the next-link action. If I want to simply read a wikipedia article and completely ignore the links, I can't, because there is no guaranteed way to simply page-down at any given point. On the other hand, by using up/down for page-up/page-down on press, and smooth scrolling on hold, I can always move by a chunk or a small amount from anywhere. By assigning left and right to next-link/prev-link, I can separate my browsing of the page from the arbitrary link layout and do just what I want, and I can use the autorepeat on the link selectors to quickly jump through a bunch of links to the one I want. select link: you have that as east, I'd use north (select control). Same functionality. We chose to use E for a main action/select button due to the check mark on the button, which maps to the check on the enter key. TOC: you have that as east hold, I'd have it in repeated east hold (see below). Note that in my mapping, the TOC (list of all available links) relates directly to to the primary press function (select-link), in that it offers a list of all the possible links one could select. back(/switch tabs nav overlay on hold): you have west, I'd have south (app-defined). Same functionality. Also, note that mappings of such pairs often make sense in a particular axis. I made forward/back E/W since this mirrors the buttons for the same purpose in the toolbar. Volume up/down keys (consider a media player) would make more sense being N/S, while ff and rew make more sense as E/W. I think that these intuitive directional mappings would make the handheld controls easier to manage. panning overlay: your use of south. Might be

Kernel configuration options
one good reason to avoid modules where we cn is that each module that gets loaded wastes a partial page of memory (arguably ~2k/module on average), on a system with only 256M ram this can add up to be a noticable amount of memory lost if you go the route some advocate and make everything a module. and given that there is only 1G of 'disk' available to the system to store modules, I would argue that trying to provide modules for all sorts of esoteric hardware (USB video was mentioned) is a waste of resources. make the other modules available for download and installation as needed, but don't eat up the space otherwise modules are useful for when you have hardware that's used very infrequently and the driver is fairly large, but I don't think that there are many cases where this is a good argument. I've always built my kernels as monolithic as possible, even for my laptops, so I know that it can be done (except a few drivers that need to load firmware). while there are some (vocal) kernel developers who feel that the kernel shouldn't even understand disk partitioning, and that everything should be a module, there are many others who feel that the kernel should not require external assistance for simple situations. Linus has commented that he also builds his kernels monolithic rather then with lots of modules, so we're in good company if we choose to do the same. rant I haven't compiled my own kernels for the XO yet, so I don't know how much can be tweaked to reduce the size, but it looks like there is some room for tweaking. however, the biggest benefits look like they would be in cleaning up the userspace boot process. there is a _lot_ of stuff started that may not be needed in the stable hardware environment of the XO laptop where there is really only one program active at a time (dbus comes to mind) remember that XO is based on Fedora, which is designed for maximum features and flexibility, not for efficiancy. This translates into poor performance for the user. I know that the XO has a slow CPU, but I just recently retired a 333MHz laptop that I was running Slackware on, and it was far more responsive then the XO is (even with a faster CPU and a solid-state drive). there is a LOT of room for improvement here. /rant David Lang ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Project hosting application - TalknType
Agree that this is a worthy project. Two suggestions: 1. Chunking -- It would be awesome if the word pronouncer could pronounce using chunking as well, the method literacy teachers use to help emergent readers learn phonics decoding skills. See links on the Phonics page for some resources about this, especially the Canadian phonics site that provides word lists with specific sound combos. 2. Like some other activities for young children (gcompris comes to mind) it would be very beneficial to have an underlying python word bank library that would return word lists and (optionally) images according to a tagging scheme. This would allow an integrated focus on vocabulary lists and learning progression in a classroom setting. It should be accompanied by a means for teachers to easily supply the lists and the tagging. I admit that I don't know the applicability of this to the teaching of reading in languages other than English, however I have discussed this idea on #olpc-content with MartinMai of omegawiki, and he thinks it would be possible to add phonetic spelling as a field in the data and associated machine-friendly access interface there.

loss of wireless after joyride-1496 update

I updated from joyride-1492. The original update from 653 to 1492 had problems when trying an incremental update, but olpc-update went on and continued with a full update that apparently worked. Wireless still worked for joyride-1492. I wanted to try the update to 1496 to see if the incremental update would work with the 'smaller distance', but it failed the same way (the first error referred to 'localtime', I don't have the exact output, I'll collect it next time). olpc-update then did a full download, which apparently succeeded, except that I no longer have wireless. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Good point, but if we left just that in place, we'd have to ask people to use the ugly text console more often, where the keyboard works partially and there's no cut paste. It's not ugly if you ship the nice 15x30 font I made. Where is it? Does it include a decent amount of unicode glyphs? sun12x22 has too few of these, so it doesn't even support many European languages. I have about 2000 glyphs, but Linux currently can't handle more than 256 (or 512 w/o bright backgrounds) because the internal representation is still tied to VGA. I thus trim my font to the regular PC character set. If the kernel were fixed though, you could have 2000 glyphs. The 256-glyph file is attached. Cut-and-paste can be fixed, with the difficulty depending on how perfect you want it. One can run gpm. This can be started when a user logs in on the console. One could even write something to feed that into the X clipboard and back. Yes, theoretically. But we don't ship gpm and we don't want to put much more effort on improving the console environment that only UNIX die hards like me and you enjoy using when we still have a journal that eats files and a mouse cursor that flashes when you render below it.

Re: Printing and the XO
Which teachers or schools have been asking for printing support? A few years ago I went to a tech for education conference in Portland Oregon. The teachers at that conference only wanted programs that had the ability to print out student work. Printing is necessary for the public display of student work. This is necessary when you want a record of what the student has done as well as when you want to show others what the student has done. At that time students worked on lab computers so a method of taking examples of student work home was needed. Also it was a way of building a portfolio to justify the use of computers in the classroom. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

[16:04] Mitch_Bradley In any company that size, there are some number of good people. [16:06] jg Mitch_Bradley: could you take a look at 5680, from your friend and ours, gnu? [16:07] Mitch_Bradley That is a tradeoff. [16:08] cjb I'd be more happy with the decision to ship G1G1 with dev keys needed if someone would own up to having made that decision and would explain it. [16:09] cjb It seems like at the moment people who didn't make the decision are providing retrofitted explanations for why it might have made sense. [16:09] jg who is taking minutes tonight? [16:09] Mitch_Bradley cjb: You know that decisions at OLPC are never made for clear reasons. [16:09] Mitch_Bradley There are made in meetings where everybody talks at the same time. [16:10] cjb Mitch_Bradley: Right. But if someone says Actually, this wasn't intentional, and someone at Quanta thought it was what we wanted., then we can correct it without having to go through the retrofitted argument. [16:10] Mitch_Bradley I think it was intentional [16:10] Mitch_Bradley But was wasn't made for a crystal clear reason. [16:10] dgilmore Mitch_Bradley: isnt that all meetings [16:10] m_stone It was definitely intentional and made for multifarious reasons. [16:11] dgilmore /decsisons [16:11] jg m_stone: in practice, it's not working out well. [16:11] Mitch_Bradley I expect that the majority of G1G1 users are perfectly happy with the status quo - apart from the ones that have DOAs. [16:11] m_stone jg: so are we currently attempting to reach a decision on whether to change the policy? [16:12] Mitch_Bradley but the developers are much more visible to us [16:12] m_stone or are we simply attempting to decide on why we think the policy was put in place? [16:12] jg m_stone: not at the moment... [16:12] cjb m_stone: I don't think either decision can happen without neuralis. [16:12] jg I was mostly just asking Mitch to look at the part of gnu's suggestion that made the most sense to me... [16:13] Mitch_Bradley which part is that, exactly? [16:13] cjb I'm guessing the last part of the second-to-last comment [16:13] jg protecting the flash from malware does not require locking off the firmware, just write protecting before transferring control. [16:13] cjb which states that the reason we turned it on can't involve malware. [16:14] jg since the update is done using signed firmware, and by the firmware. [16:14] cjb so we need to know whether the decision to turn it on was made for that (malware) reason. [16:15] m_stone I had always understood the point of the developer key mechanism to be 'by requesting and using this developer key, you assert that you are taking full responsibility for maintaining the system in your possession' [16:15] cjb so that we can know whether the reasoning behind the decision is vacated. I think the hypothetical people who would have made the decision already understand/understood that. [16:15] jg enough of this topic for the moment, I think [16:15] m_stone From that perspective, requiring G1G1 customers to request and use developer keys to access the firmware serves two purposes: [16:15] cjb But arguing based on so much mindreading and with so little presence of people who actually made the decision is irritating. Moving on sounds good. [16:16] m_stone as a 'warning flag' that by using such a mechanism, they have entered dangerous waters. [16:16] Mitch_Bradley we need to have a scheduled meeting on the topic, with an invite list, and a voting procedure. Robert's Rules of Order, perhaps. [16:16] m_stone and as a means to generally perserve our ability to remotely restore machines to a known-good state by distributing signed firmware scripts as necessary. [16:17] m_stone I am content with Mitch's suggestion. [16:17] jg subject for another time and meeting. [16:17] Mitch_Bradley There is a reason why formal meeting procedures evolved...

Having been a computer teacher for several years, I set up a network printer for those teachers who requested it, (but it was a CONSTANT hassle, from paper jam problems, to misconfiguration, toner cartridges, etc. I got around the problem by handing off the problems to windows techs, which left me to the paradise of just running a linux lab ;-)).

Then it was always available, never lost, shown to other students, parents, teachers, etc. at any time! ;-) (And optionally, could be placed on the worldwide web, as opposed to just a school network/server, if one really wanted to 'display' work, etc.) ;-) A much better solution, I found. :-) Heartily recommended, as opposed to the archaic method of printing out reams of paper, multiplied by millions of students/teachers/parents, at considerable cost to the environment, etc. Never miss a thing.
