Re: [IAEP] [Sugar-devel] Children want Sugar 0.84, for the wrong reason
I have been unable to install Bernie's OS67 or Steven Parrish's os12, Bernie and I have been discussing this off list. If anybody has the same problem please let us know. Detailed instructions on the installation process are at http://wiki.laptop.org/go/Clean-install_procedure#Development_builds In brief, you need a developers key for your XO because it is an unsigned build On a USB, save the devkey to /security/develop.sig save the img and crc to root Turn on with the USB plugged in and the esc (x) key pressed type probe-usb copy-nand disk:\os67.img after the reflash finishes, turn off, remove the USB and power up My XO fails with "Boot Failed" I can restore OS767 in the same manner http://download.laptop.org/xo-1/os/official/ Tony > On Sat, 2010-03-13 at 13:26 -0500, Gerald Ardito wrote: > > > > Where can I download this image? > > I've uploaded one of our builds here: > > http://people.sugarlabs.org/bernie/olpc/py-xo1/ > > It's slightly newer than the version we've been installing on children's > laptops, and has been lightly tested.

I've noticed some annoying graphics artifacts on buttons, probably caused by a geode driver bug exposed by the gtk theme. I've been focusing exclusively on Sugar and core activities. Gnome is very popular among children, but I'm not particularly motivated in supporting it. Frankly, I also don't test Sugar beyond very basic functionality: networking, journal, browse... Not only I wouldn't have time to comprehensively test every activity, I also wouldn't do the same things that creative users actually do with them. Instead, I've invested on building a testing team form a small crowd of smart children who are using their laptops 6 hours a day. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ IAEP -- It's An Education Project (not a laptop project!)

Slowing down deployment of new versions might make things even worse! The more changes accumulate, the less familiar the new version will look like, and the more time the users got to get used to the experience provided by the old version, no matter how buggy it was. The Vista vs XP effect. The only way to reduce user adversity to change is getting them used to smooth change by providing a short development cycle with few changes that deliver clear improvements to the user experience in terms of new features or fewer bugs. The #1 bait we used to push this new release onto teachers was 3G support. Suffice saying, GSM connectivity is very popular in places with no wired broadband. Unfortunately, this wasn't quite true, bacause many popular Huawei modems use by default a "Windows compatible" mode in which they show up as mass-storage devices. After backporting udev to F-11, I found out that now users are being sold an even newer model of Huawei modem which is not yet supported by the Fedora 12 version of udev's rules. Teachers blamed the new Sugar for breaking their shiny new modems: they seem unable to distinguish between a regression, a bug in new feature, or an entirely missing feature. Heh... Anyway, now I found a temporary workaround and reported the missing feature upstream: http://bugzilla.redhat.com/show_bug.cgi?id=573250 Too bad it was so easy: support for new devices would have maed a major selling point for the next version of Fedora :-) -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ IAEP -- It's An Education Project (not a laptop project!)

Depends very much on who you ask to. Teacher / trainers: It deleted my stuff I can't learn it None of the new activities work We can't work any more with this new version This GNOME thing has many drawbacks GNOME prevents activities from working Children: Please install "colored windows" The new Sugar is faster How do I get to "piecito"? (little foot == GNOME) I like the screensaver ...many more... If you ask me: our recent F11-XO1 builds have reached equal or better quality than build 801, provided you disable automatic power management. Activities still need some bug-fixing, but nothing serious. I filed a bunch of bugs in the SL and OLPC trackers. I asked educators to send us clear and complete bug reports every time they see something odd, but all I've seen so far is distress calls, of course sent through private channels instead of the ones I suggested :-) I think this is all natural: non-technical adults tend to panic on the idea to replace something familiar with something that will force them to learn something new. This is the first time in their *lives* it happens, so we should be understanding. In less than 2 months, they'd be happy with this version and unable to use the old one. Hopefully, they will complain a little less on the next upgrade to 0.86 and 0.88...

Re: [IAEP] [Sugar-devel] Children want Sugar 0.84, for the wrong reason
See http://bugs.sugarlabs.org/ticket/535#comment:5, Expose Journal, Home, Group, Neighborhood, & Frame Sources, where it's suggested that we extend the 'Show Source' facility to more of Sugar. Learners like to exercise and demonstrate their knowledge by customizing or changing their environments. We can guide them to learn deeper concepts by giving them ways to encode their customizations. (Providing a convenient undo, save, and restore facility for their work would accelerate their learning.) The 'Modifying Sugar' chapter in our manual, http://en.flossmanuals.net/Sugar/ModifyingSugar, provides a nice entry ramp for this learning activity. We could provide a similar tutorial for other Sugar features and then benefit from the creativity of all our learners.

We use a local variant of the F11-XO1 images by Stephen Parrish, signed
with the deployment keys.
The procedure for each laptop is:
(1) backup the lease.sig to a USB stick
("cp /security/lease.sig /media/PENDRIVE")
(2) reboot while pressing all 4 game keys
(3) wait for about 3 minutes to load the image
(4) boot with the USB stick still fitted to re-activate the
laptop
If your laptops are unlocked, you can save steps (1) and (4) and you
don't need a signed build. The procedure would become:
(1) press ESC on boot to get to the ok prompt
(2) type "copy-nand u:\osNN.img"
(3) wait for about 3 minutes to load the image
See my reply to Bert in this same thread for some considerations about
Journal backup/restore.
The scripts I mention in that post are available from our public
repository, but atm I can't reach the office to retrieve the link.
They're really crude scripts, no big deal. It would be really cool if
someone could work on a bootable USB stick which would automatically
perform full backups and restores. Not only it would save time, it would
make students and teachers more autonomous from us techies.

I feel that Sugar should aim to reach the same level of "hackability" of eToys: every UI element is an object that you could drag, drop, copy or modify. Of course, this has consequences in terms of stability and clarity. Before we could unleash this power we need to think of ways to recover from mistakes. If multiple undo is too hard, a "restore everything to defaults" might be good enough. Perhaps we're worrying too much. Re-installing the system from USB takes only 3 minutes and is already being done very often. A boy just showed up on the door of the repair lab, saying: "se borró el Navegador" (the Browse activity deleted itself :-) All we need to do is make the backup-update-restore procedure slightly more automated so that kids and teachers could do it without bothering the technicians. Actually, we don't even need to worry too much for a solid backup and restore procedure. I've always suspected that most kids wouldn't care about preserving their diary. Now it's confirmed: kids are flocking here to get the new version of Sugar even though their journals are not going to be preserved across the upgrade. On the other hand, teachers and teacher trainers always ask to preserve the content of their journal. Technicians use a pair of simple shell scripts to tar up the journal to a USB stick, so they don't depend on being within the range of the correct school server. I'll summarize all these things in a field report asap. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ IAEP -- It's An Education Project (not a laptop project!)
