More Planning Thoughts
Dear devel@, While I'm still rather far away from "done", I may have imposed enough structure on my present fragmented reflections on our goals to be worth your review [1]. [1]: http://teach.laptop.org/~mstone/planning/r1 As always, questions & comments are greatly appreciated. In this particular email, I'm most interested in thoughts that my commentary inspires in you and in your contributions toward my "represents the diversity of justified views within the tech community" goal. In future emails, I will be more concerned with your analysis of the quality of the justifications given and of the appropriateness of the proposed primary and backup plans. (Also, this week, particular thanks are due to Greg for his excellent and intriguing discussion [2] of, in my words, "how to avoid painting your team into ugly corners".) [2]: http://wiki.laptop.org/go/User:Mstone/August_planning#A_suggestion_on_how_to_reach_a_decision_quickly Michael P.S. - (Feel free to wikify if it matters to you; I certainly appreciate the feedback I've received on [2], particularly Greg's comments [3]. Alternately, would people find something like the FSF's GPLv3 comment system, the Django Book's comment system, or the Real World Haskell Book's comment system handy for preparing this sort of planning document? If so, can anyone volunteer to put up an instance? Alternately, does TOPP supply anything that addresses the communication problems posed by documents like this one?) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: fun and games with trying to un-suspend
"I too" since before joyride 1850 (sorry, I don't know exactly when it started.) I have no SD card in slot. I frequently travel with my XO around town during my various meetings and volunteer activities. Great little device for taking quick notes at the table. :-) Take it to one meeting, take notes in Write... when done... close the lid. Off to the next meeting, open lid... light above camera blinks on/off. I push around on the touchpad to active... light blinks again screen appears for a split second, then goes dark. I push a few keys, the light blinks evertime I hit a key.. but screen doesn't come back. I've figured out by trial and error, holding down the power button for 5 seconds... release.. and it comes back. However, if much longer than that shuts down completely the power. Unfortunately, two of the meeting notes/minutes I have taken are *poof*. I opened them up a few days later, and only a few words in the Journal saved session. :-/ I never clicked on 'Kept', and had assumed that the Journal would save the latest version. I suspect that the suspend feature either corrupted the document during going into suspend mode.. or later on.. after a joyride update... the document was corrupted. I have a backup [1] of the /home/olpc files shortly before one of the meetings, and still trying to hunt down possible fragments. But I believe the other one is gone for good. :-/ Got to be more careful in the future. I think frequently clicking on 'Kept' may minimize the possible corruption... Along with clicking on (and completion) of 'Kept' a few minutes before closing the lid... may help too. (I typically close the lid while Write is open, maybe returning to 'home' before suspend will also help?) :-/ Sadly reminded that 'joyride' is actually a beta product. --Ixo [1] My handy dandy 'xo-backup-server', from http://wiki.laptop.org/go/User:Ixo/Script > 2008/4/15 Martin Dengler <[EMAIL PROTECTED]>: > > I've had these symptoms often over the course of the last two months, > > with various update.1 / joyride builds.

Re: VoiceThreads ... a very interesting education service
Wow, thanks for posting that link – what a lovely site. It actually already feels pretty close to a possible Sugar activity, and would fit right in with the XO's hardware features. Actually, I think Record is already pretty close to a whole bunch of these features** with its shared and annotated images/audio/movies, it could be used in a similar way***. ** except for the (my opinion) design flaw where you can't share existing recordings, only ones you record after someone else joins a shared session – so no point taking a bunch of photos of things and then clicking share – no one sees anything. For a test, a while back, I set up a Record session, named it 'View out your window', took a couple of photos, and turned sharing on. A bunch of folks joined over an hour or so and left photos of their view, but they couldn't see my photos, and I could only see a thumbnail of their photos (gave a network time-out error if I tried to click a thumb). Still a fascinating exercise even if it didn't quite go to plan (showed the potential). *** If you could resume a pre-recorded Record activity *AND* then share it out, it could be a good way to do photo journal type homework or research. Perhaps needs a better playback mode (text notes and images shown at once; ability to reorder the items in the bottom pane; ability to take a photo, then record audio associated with it). Maybe if Journal item sharing arrives as some point, this will be a practical way of generating and sharing similar content.

The easiest solution, and the one I recommend, is to make the TamTam activities into a single activity. There is no need to have 4 distinct activities. Switching between screens within one activity seems much more reasonable than running multiple distinct TamTam activities. I cannot keep track of which one is which.

I am not sure about the current state of datastore security; I believe it is minimal. However, if you follow this pattern, you will be appropriately future-proofed. In the Bitfrost design, P_DOCUMENT_RO is mutually exclusive with P_NETWORK by default. If you require both P_DOCUMENT_RO and P_NETWORK for a single activity, you may request this additional permission at install time.

Handling TamTam Resources...
Hi all, I'm working on sharing resources between our 4 activities with respect to the security policy. It will be very helpfull if you have time to give me your opinion on the problem... Here is the situation: TamTamJam and TamTamSynthLab produce sounds that we want usable by any TamTam activities. Each sounds come with a little text file specifying some attributes of the sound (loop points, crossfade duration, amplitude, ...). Before security policy, all our stuff was saved in .sugar/default/tamtam and all activities was looking there for resources... that was working very well. Now, I moved all permanent saved stuff to DATA_DIR and everything work except that others TamTam activity (e.g. TamTamEdit) can't use sounds saved in TamTamJam's DATA_DIR. Is there a way to let all TamTam activities have access to a common directory? How do think this stuff should be implemented? Thank you very much!

If the cursor movement stops then for some time Sugar should watch the cursor and if the user moves past the screen edge by a large amount only then should it show the frame. Unfortunately it would require Sugar watching the raw touch pad input since the cursor cannot leave the screen area.

Well, this is a "yes and no" answer. I think that it will greatly reduce the phenomenon, since it will "take away" all of the icons which allow them to launch more activities by default, requiring them to explicitly return to the other views to launch more. Kids won't just be able to click the next icon they see on screen. > My impression is that it will help a lot. Still, it does sound like a > good candidate for a trial with a few real kids.

The pulsing could potentially slow the launch slightly, but I think it will be minimal.

We've recognized that accidental activation of the Frame is a problem, but haven't had time to implement any of the proposed changes. The simplest change we hope to add is a tiny delay, to prevent accidental activation when attempting to reach a button or element near the corners. Even a very small delay of, perhaps, 1/5 second should help reduce this. We'll likely add a slider to the control panel allowing this value to be adjusted from instantaneous to off.

I have a permanent SD card which I (manually) use for my "datastore" (I'm not a Journal lover). I wrote up #6584 because I'd as soon have the OLPC software KEEP ITS HANDS OFF my SD. [I'd be perfectly happy to do the 'mount' myself.] http://lists.laptop.org/pipermail/devel/2008-February/010870.html suggested a way for me to prevent scanning of my SD (presumably including when coming out of suspend). At that point in time, I made the changes to volumesmanager.py, and it worked as I wanted. Unfortunately, as I kept updating to more recent OLPC software versions, this "patch" stopped working. As far as I can tell, I was applying the same code instructions as before - so the resumption of scanning (despite my "patch") might have been due to OLPC software changes elsewhere. Though I would want to *inhibit* the XO from scanning my SD, I don't currently know how to do that. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
RE: Activity Launch Notification
Hi Eben, Thanks for the comment and for covering all the bases. I'm not sure what zoom level means or what the frame will look like in this case. Regardless, if the kids can still launch other activities you may want to check this design to ensure it covers the basic challenge raised by Carol in the SouthBronx class. That is, does it prevent kids from clicking on lots of things because they run out of patience while waiting for the first to load then end up with too many activities running and the whole system slows to a crawl? My impression is that it will help a lot. Still, it does sound like a good candidate for a trial with a few real kids. If you can mock it up, maybe Carol can take it back to the class for a sanity check. Its certainly better than the blinking icon so even without a trial you should probably just do it. Seems like a sure win unless there is some other negative side effect (greater memory or disk usage, launch time much longer, harder to code new activities, other?). My 2 cents.

First, this launching screen will take the place of the activity zoom level for the launching activity, before the activity window itself appears. The Frame will remain available, allowing the kids to switch away from the launch, in order to continue working in another activity, launch additional activities, or browse the other zoom levels. As such, they'll never be "locked in". Second, there's the issue of "force stopping" activities. I brought this up as something I'd like to support a while back, but found that it is complicated by the manner in which activities are launched, since we don't necessarily know the process ID it's running under during launch (or something like that...Marco can clarify). In any case, if we can do it, we should, offering a "Stop" button in the palette for the launching activity. If we can't, it's still not a showstopper, since it's possible to switch away, and the launch will timeout eventually, preventing the pulsing icon from forever haunting the Frame. - Eben ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Salut uses avahi, so you can see what salut sees if you run "avahi-discover" (on Ubuntu, you need package avahi-discover installed). (Or you can use avahi-browse for a text-mode equivalent - I think both are available on the XO.) Running avahi-discover on my laptop while I have a jhbuild instance running, shows "iChat Presence" > "[EMAIL PROTECTED]" which is the salut instance on my laptop. Clicking on that entry shows the properties of the salut buddym including "TXT nick =" If you share an activity, you will see it appear in avahi-discover as "_olpc-activity1._udp" and also appear in "_clique._udp". If you are not seeing any of this on the openSUSE machine, then perhaps the setup instructions for that distro are missing some dependency or something. Let us know. > I know you have a lot on your plate, but information on diagnosing Salut > problems would be a good addition to the Wiki. I'll add the above avahi stuff to the [[Telepathy Salut]] page and/or [[Telepathy debugging]].

Basically Gabble will run when you have internet access (a valid IPv4 address) and can connect to the configured jabber server. If it fails to connect, or disconnects, or doesn't get an IP address, Salut runs. A very quick test for which one is running is: "ps ax |grep telepathy" - if it shows telepathy-gabble, you're on a jabber server. If it shows telepathy-salut, you're on salut. If it shows neither, then something made salut crash - please log a ticket and attach logs if you have them enabled[0].

The deal with crossword puzzles is that you only need to put in the exact glyphs that are in the crossword puzzle, whereas scrabble will have to have every single one. In Nepali, the number of devnagari letters we use (vowel+consonant) is 36 * 12 + c where c > 0, for some "extra characters." To illustrate what I am saying: in a crossword puzzle that has the word होली, you can just use other words that utilize हो but not any of the other vowel conjugates of ह, ie हा हि ही हु हू हो हौ हे है हं ह: . In scrabble, you'd need to provide all of these as tiles that one could use. The set of words in crossword puzzles is limited, and therefore the set of glyphs used, much smaller than the number I listed above. And there is still the issue of half letters. ie. words like कुर्ता (क ु र् त ा) चिन्ह (ि च न् ह or च ि न् ह )? -prabhas ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Severe new bug in firmware Q2D13?
Some of the machines from the first production run had bad battery holders. Not the main battery, but rather the small "coin cell" battery on the mainboard that powers the time-of-day/calendar clock chip. Those battery holders have a plastic retention lip that holds the coin cell in place. On the bad ones, the lip is too small, and the batteries can become loose or even fall out entirely. When this happens, the time-of-day/calendar clock chip loses its power, forgets what day it is, and resets to the earliest date. The long-term solution is to replace the battery holder, but I don't know what the logistics of this would be in your situation. It might involve swapping the main boards and sending the bad ones to a repair depot, or perhaps sending the entire laptop for repair, or perhaps getting a supply of the battery holders and replacing just them. As an interim solution, it might be possible to use glue to hold the coin cell battery in place. Open the laptop, insert the battery firmly in the holder, and put glue around the rim of the holder where the plastic contacts the battery, taking care not to put glue on the metal contacts. You might want to experiment with different kinds of glue that you have readily available to find on that sticks to the plastic battery holders. I am doing some experiments here. So far I have found that hot-melt glue does not work well (it doesn't stick). Solvent-based household cement seems to stick, but I haven't had time to let it harden fully. I am also trying white glue (polyvinyl acetate). I'm pretty sure that epoxy would work, because it sticks well to a lot of things, but it is slightly harder to work with than one-part glues. "Super glue" (cyanoacrylate) would probably work too, but I don't have any handy so I haven't tried it. After you have secured the battery in the holder, activate the laptop, then use the Linux "date" and "hwclock" commands to set the system date. (Or "ntpdate" and "hwclock" - see http://wiki.laptop.org/go/Customizing_NAND_images#Time) If you have developer keys for those machines and a wireless access point that is connected to the Internet, you can set the date from the firmware: ok wifi MYSSID ok ntp-set-clock where "MYSSID" is the SSID of your access point. That assumes an "open" access point. If the access point uses "WEP" security (which isn't very good), you must first set the key with: ok wep 123456789a where the argument is a 10-character or 26-character hex number. If the access point uses WPA security, you must first set the "preshared key" with ok wpa where the argument is a 64-character hex number. WPA authentication can be complicated, so it might not work for you.

How to use Salut?
Morgan, Thanks for the information on ejabberd. I may try that this weekend. I am still puzzled by salut, though. I am using sugar-jhbuild on openSUSE 10.2 and everything seemed to compile OK, but running two instances of Sugar does not seem to support sharing when the Collabora server is down. They don't see each other in the Neighborhood view. So it looks like Salut isn't doing its job. I know you have a lot on your plate, but information on diagnosing Salut problems would be a good addition to the Wiki. Speaking of the Wiki, I did a search on Salut and the page I found gave the impression that Salut only works when there is NO internet connectivity.
