Re: [OLPC library] OLPC-health
I haven't used InDesign, but in my many years using FrameMaker I considered it fairly beta the whole time. Basic design errors, memory leaks, missing functions, display bugs,... Yes, Adobe's previous product PageMaker/FrameMaker was very beta as well. I have a pretty soft spot in my heart for it's fellow users :) We may need to send a few volunteers to clean up Scribus, then. Has anybody on the devel list looked at what needs to be done for Scribus? They could start exploring here. http://bugs.scribus.net/roadmap_page.php Maybe we should start a Wiki page for Free Software projects that are needed for laptop work, even if they won't go on the laptops. That's not a bad idea. We have only X number of programmers coming into the project, if we can't get them to work on one of our projects *directly* perhaps they could work on related projects? I'm trying to make the wiki a little more usable for people looking for jobs, and I'll keep this in mind. We need a project page for each activity, each document set, and much of the basic hardware and software development, and we need to prod people to sign up there. Then we have to create pages to index it all, or at least make sure that category markers are applied consistently. This is what I've done for the [[Health]] projects, and I'm working on expanding into other projects as well. (we ought to talk about VistA soon btw) I am concerned with how we are using signup lists on the wiki however. No one ever seems to *do* anything with them. I haven't really seen anyone go back into a /People list and contact the new recruits. It makes much more sense for them to hit the mailing lists or contact someone directly. I think that every page/project needs to have a volunteer coordinator. Just someone who can farm work out to more people, and has a basic to middling understanding of the components of the project and can connect people to those who know more. That in fact should be it's own thread come to think of it. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: prevent data loss in running activities
Looks like the new gnome-session is a good candidate: http://live.gnome.org/SessionManagement/NewGnomeSession http://svn.gnome.org/viewvc/gnome-session/branches/new-gnome-session/ We can use EggSMClient for activities, it's planned to go in gtk when it's ready. The dependencies of the server looks sane, except for libgnomeui which is easy to rip off (and I'm sure it will be made optional at some point upstream too).

How to create a new MIME type for a Sugar activity?
I am writing a Sugar activity in Python. This activity will enable the user to navigate through a list of image files stored in a Zip file by using the arrow keys, and might support a slideshow feature too. There might be a hundred image files stored in the Zip file. Grouping the images in one file makes it much easier to deal with them in the Journal. The thing is, I want this Zip file to have its own MIME type, so that: 1). The Etoys activity does not try to open the file, at all, ever. EToys takes a long time to start up and shut down and it is really annoying when I open the file with EToys instead of my own activity. 2). My Activity *does* open the file. 3). The Zip files containing images show up in the Journal with my own Activity's icon, which looks like a slide projector. To accomplish this I have created my Zip files with the extension .slides and I'd like to be able to use the MIME type application/slides for such files. I'm also interested in creating a reader program for Gutenberg etexts. I'd like these files to have their own MIME type too so they don't get opened by the Write activity by mistake. I was thinking of using a file suffix of .book and a MIME type of text/book for these. I tried using a mimetypes.xml file in the bundle but that didn't work. I couldn't find an example of an Activity that used such a file so I'm not certain I'm doing it correctly. I'd appreciate any information on MIME types or on alternative approaches that would solve problems 1-3.

I think this should be covered in the dragability of each individual hand. Very good! Another ticket that seems to inspire you (http://dev.laptop.org/ticket/2778) This was the main basis for the project, and we believe we addressed all the issues raised in the comments. Some say that designing is completed when nothing cannot be removed. In other words, trying to address all the issues raised by random people is not always a good idea. (It includes the issues raised by me as well!) Of course, by addressed all the issues raised I didn't necessarily mean included in the design. discusses timezones and collaboration. But I'd say that these are secondary issue. Who believes that it is worth to pay the effort to have kids in Nigeria and Brazil look at each other's clock and discuss something (Could they discuss something worthwhile?) If you can move hands at will, that would be much better. The time game would allow for collaboration, and also for (perhaps) meaningful discussions between two children I was talking more about practical issues like the language difference and (yes) time difference, 12 hours vs. 24 hours notation difference, etc. As you wrote below, kids won't discover these concepts by their own. Translating the 12 hour to 24 hour notation of the submission to whichever the other player is using shouldn't be a problem. Also the game isn't time zone dependent. Do you envision that these two kids connect to each other when they don't understand what the other's language and find a good time of the day when they can connect, and discuss about an artificial and abstract concept like time? True, perhaps discussions would be less helpful, but I think the time game is still something that would help. As a child you can't understand time(in the form of a clock) until it is explained to you. Which is where this activity will (hopefully) come in. I wasn't saying that kids can make stuff before understanding it. There needs to be good guidance that leads them to the deeper understanding. (For some more background, refer to some discussion around http://squeakland.org/pipermail/squeakland/2007-August/003719.html and hopefully the video linked from the email.) You wrote that your Time activity have analog, digital and natural display of time but with these, you have to explain it to kids. What kind of supporting material do you think is needed? Can the explanation be on the laptop as well? Can it be interactive? Can the explanation and the real thing be seen on the same screen at the same time? I think the natural time clock should be close enough to the actual appearance outside so that the children will connect the ideas. Also, the clock can be updated to the time it is right now. Thus in that way it should be its own explanation. It appears that you are a high-school student... That is really great! Please don't take above as discouragement. I'm really trying to encourage people who are trying to make educational activity (as you know, there aren't many for XO.)

I think we need to seriously discuss about possibly/probably being update.1 fodder is the kids arrive at school in the morning problem. 5 - Use of mesh in large, crowded environments If everyone arrives at school running local link and resumed quickly, the network might melt from mdns mesh traffic's interaction with the mesh's implementation of mutlicast. We've upped the multicast bitrate for multicast as a band aid, until we can dynamically adjust the bitrate. But the fundamental issue comes that in large, dense school environments, can't expect multicast to scale far enough, and should be using unicast to a presence server (jabber in our current case) to handle this problem. Dave Woodhouse has suggested may be to try to get a response to the school server's anycast address, and if we get a response from a school server, switch from Salut to Gabble for presence service automatically. This is also somewhat mitigated by having working power management, as machines that have suspended due to idle stop sending mdns packets, and the kids presumably will want internet access and switch over when they arrive. But I'm not very confident that this will always work in large environment. Another temporary solution would be to have Ohm ask NM to reconnect if the machine is suspended for more than some interval, say, 30 minutes. -- Jim Gettys One Laptop Per Child ___ 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

We were looking for a way to change the position of the sun based on the longitude and latitude and time of year(xearth seemed promising). I'm actually not sure how china deals with time zones, but as long as the laptop's system time is correct, I don't think that should be a problem. It would be nice there is *also* an abstract form of explanation. Also, the clock can be updated to the time it is right now. Thus in that way it should be its own explanation. Ah, but stuff like 60 seconds is 1 minute, 60 minutes is 1 hour, 24 hours is a day, but the face only has 12 numbers, etc. are not that discoverable. Hopefully that would be something they would notice with moving the clock hands and seeing the digital clock change to 59 seconds/minutes before 00 It appears that you are a high-school student... That is really great! Please don't take above as discouragement. I'm really trying to encourage people who are trying to make educational activity (as you know, there aren't many for XO.) It is really valuable to see that somebody (who is young and close to the target age group!) think about making activity. I am a senior at IMSA, and am aware of the development process, so I know your comments aren't discouragement. Thanks! Do you know Kathleen Harness? Should I? Well, she is helping Etoys activity contents development, and her group at http://www.squeakcmi.org/index.php is for example hosting an OLPC meeting (as on the web). Also, she was on a local newspaper recently. When I attended a conference in Chicago, a presenter from UIUC gave a talk. In the talk, she showed a blank map of Illinois and started with a remark: Welcome to Chicago! But do you know that, outside Chicago, there is a larger area called Illinois? For an outsider like me, Illinois is one thing so I thought you might know her.^^; I see your point, but seeing as cooperation in the olpc project started with the new year, I don't have any connections outside of the IMSA chapter. -- Yoshiki ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: SD card errors on resume after suspend, joyride 1634 firmware q2d12
It may be possible that you could find others experiencing the same problem on the support forums. Check out http://forum.laptop.org/. Cheers.

Re: Pen Tablet firmware test doesn't work on beta2 machine
Significant changes were made between a B2 XO and a mass production XO laptop. As a result, the B2 laptops are no longer supported by current software builds and not recommended for development work.While it seems a shame to abandon hardware in the field, all the B2 machines built number less than half a single day of XO mass production, and our development/test resources are stretched trying to properly support just the mass production machines. John On Feb 4, 2008, at 4:59 PM, Patrick Dubroy wrote: I've got a beta2 machine, and access to a beta4 machine as well. On the B2, when I boot into the firmware tests and get to the Pen Tablet/Glide Sensor test, I get absolutely no response from the Pen Tablet. The Glide Sensor (touchpad) works fine. I've also tried running 'evtest /dev/input/event5 1' and that also fails to detect any input on the tablet. On the beta4 machine, both of these tests worked as expected. Any idea why the touchpad wouldn't be working on the beta2 machine? Does anyone else have a B2 that they could test? It's possible I've just got some bad hardware.

Re: disabling root and olpc passwords
I posted because there appeared to be a regression (regarding asking for passwords) in the OLPC behavior -- that exists regardless of how I described happening to notice it. The theory is that in update.1, the olpc and root accounts will come disabled (locked with a password that nobody can type). However, you can change the password by becoming root (using sudo, or su, or root autologin on the tty1 console, or the Become Root button in the terminal activity). Then just use the passwd command to set whatever password you like. After that, you can start incoming ssh and/or FTP sessions using your newly set password. It's easy to get confused about this -- the particular implementation strategy for update.1 has changed several times. (Indeed, I might have it wrong, but I rest assured that if so, someone will correct me.) See http://dev.laptop.org/ticket/5537, which seems to be the master ticket for this issue (there are lots of dups).

Help for kick off!
Hi, How to get started with OLPC for developing a software? Is there any area which we require to know about in particular? How can we get to know more about the architecture of the OLPC? Also the OS of OLPC and the registers it use for various purposes. Is that all the activities developed in OLPC is in Python? Can't we go for any other language? Can't we use C for it? How do we get started with the kernel level programming in OLPC? Is it exactly the same way as in Fedora? aswathy ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
