We can set a new baseline for Sugar, but the behavior you are describing is largely one determined by the activities themselves. This was the subject of Ben Schwartz's GSoC project.

Re: First semi-version of Simple Digital Library Index
SDLI can run two ways: 1. A content team uses the app as a normal desktop java app and exports it all 2. The content team just puts together the folder contents (e.g. PDFs, media, etc) and then SDLI runs on the XS from the command line to generate the browsing pages / indexes etc. Also the XS can simply have an apache config that points to the directory where the SDLI export lives... then plain vanilla apache can serve it. The problems that I wanted to solve were: 1. Making library creation fast and simple - existing systems just needed too much time for meta data arrangement etc. 2. In a limited connectivity environment how do we serve content quickly and efficiently to schools? Infoslicer grabs info. SDLI arranges large quantities of information in a way that can be browsed, searched, etc (e.g. you could use infoslicer to grab multiple bits, categorize them, and then use SDLI to make an index) We use webdump (a open source app we programmed based on httrack) to grab websites and package them into a format suitable for offline use.

If you think you might be having troubles with overheating on your XO-1.5, the heat spreader is suspect. After removal (to change the SD, check out the motherboard, etc) and sometimes even before then, the heat spreader doesn't make good contact with the VX855 and the CPU. I suggest bending the feet of the heat spreader slightly, as shown in the attached diagram, to apply more force on the processor/cpu. This is being worked on in C build prototypes.

public_rpms system for F11 builds
Hi, I've revived the old public_rpms system for the new F11 builds. For anyone that doesn't know, this is a way of making custom RPMs available for OLPC OS builds. Normally, RPMs come from regular Fedora repositories, but this system allows us to throw in RPMs from other sources. We aim to keep our delta from Fedora as small as possible, so this system should only ever see light use. Please question yourself thoroughly before adding a package to this system... (examples of what we put here: important OLPC-specific packages which can't be included in Fedora, OLPC's fork of the unmaintained Sugar-0.84, the OLPC kernel) There are 3 repos: 1. f11 - RPMs to be available to both F11-for-XO1 and F11-for-1.5 builds 2. f11-xo1.5 - RPMs for the XO-1.5 build (not for XO-1) 3. f11-xo1 - RPMs for the XO-1 build (not for XO-1.5) Any dev.laptop.org user can use this -- simply put RPM packages in ~/public_rpms/reponame e.g. I would put things in /home/dsd/public_rpms/f11 The f11-xo1 and f11-xo1.5 repos should only be used sparingly, since we want to be sharing as much as possible between the 2 builds. (the only reason for creating these 2 is because each XO HW version needs a different kernel) They are collected and turned into a single flat repository every 30 minutes here: http://xs-dev.laptop.org/~dsd/repos/ Packages you put here won't be *included* in the build unless they are listed in the fedora-xo build scripts (or unless they are a dependency of something listed there). What I'll be working on next: 1. I'll make the kernel autobuild scripts put the kernel packages here 2. I'll make it so that if you put a package here, this package will be automatically excluded from the F11 repositories during the OS build so that the F11 packages won't kick out the OLPC ones when version numbers get higher. 3. I'll work on making sure that the yum configuration (these repos and excludes) present on the system at the end of the build exactly matches the one used during the build.

Emacs love and window sizing

I am not sure how to give emacs or the wm the right window size. Hints?

For anyone that doesn't know, this is a way of making custom RPMs available for OLPC OS builds. Normally, RPMs come from regular Fedora repositories, but this system allows us to throw in RPMs from other sources. We aim to keep our delta from Fedora as small as possible, so this system should only ever see light use. Please question yourself thoroughly before adding a package to this system... (examples of what we put here: important OLPC-specific packages which can't be included in Fedora, OLPC's fork of the unmaintained Sugar-0.84, the OLPC kernel) There are 3 repos: 1. f11 - RPMs to be available to both F11-for-XO1 and F11-for-1.5 builds 2. f11-xo1.5 - RPMs for the XO-1.5 build (not for XO-1) 3. f11-xo1 - RPMs for the XO-1 build (not for XO-1.5) Another possible use-case is to quickly test a new package before pushing it in Fedora's bodhi system which includes it in the official F-11 update stream (I use this method for large/tricky changes in olpc-utils) Thanks, Sayamindu -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: OFW Q3A15
Emiliano Pastorino wrote: There is a way to check the temperature under Linux. It involves the lmsensors package, but I don't know the exact details. Yes, that's what I've been using. The package is lm_sensors, if installed, you just have to type sensors and you get the temperature in ºC. I've already checked that temperature never goes beyond 100ºC, so it is working. But how does it work? Is it just underclocking? The CPU changes the clock ratio dynamically when the temperature gets too high. I've checked /proc/cpuinfo, but clock is always at ~1GHz I don't know the details of how /proc/cpuinfo gets the clock information. You can see the clock transitions in Open Firmware as follows: ok 198 .msr show-temperature (cr many In the unthrottled case, the MSR value will be 04060a06.04000a06. In the throttled case it will be 04060a06.040c0406. The fields in that value are AABBCCDD.EEFFGGHH, where AA is the lowest supported clock ratio BB is the lowest supported voltage CC is the highest supported clock ratio DD is the highest supported voltage EE is the lowest configured clock ratio FF contains status bits GG is the current clock ratio HH is the current voltage All of the voltage fields are 06, which means that the voltage doesn't change. The minimum clock ratio is 04, meaning 400 MHz, the maximum is 0a (decimal 10) meaning 1 GHz. The GG field is normally 0a - full speed - but changes to 04 briefly when the processor throttles back to drop the temperature from 100 to 95. The FF status field changes from 00 to 0c when throttling is in process. It is possible that /proc/cpuinfo is reporting the correct information, but the throttling happens too briefly to notice the change. The CPU runs at full speed until the temperature reaches 100, then it drops back to 400 MHz, but very quickly resumes full speed operation when the temperature drops to 95. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [Sugar-devel] On Sugar 0.84 - status of the Chat/collab leader issue...
Hey, I mentioned this to Walter on IRC the other day, but I'd very much like to participate in anything telepathy based, especially, maybe moving to mission control 5 and letting go of the admittedly antiquated sugar presence now, I do need some guidance though, as I am by no means a python guru, though I've really digested telepathy and have a pretty good feeling for the dbus bindings it has, as well as the way D-tubes work. I didnt realise the power of having basically networked dbus until I really got the d-tubes. It even lends a great deal of power to things like LTSP, by being able to remotely control rudimentary elements that are otherwise quite difficult (remote volume control, rmote power off, remote switch users, remote control of many kinds... I could imagine almost a remote dashboard... much like italc, but with more power. and able to do things I havent even thought about yet I know its exciting stuff though I dont thnink I'll be able to make it to Bolzano, but I understand there will be a strong remote presences... so I'd be happy to help out in that area, kind regards, David Van Assche On Tue, Nov 3, 2009 at 4:30 PM, Tomeu Vizoso to...@sugarlabs.org wrote: On Tue, Nov 3, 2009 at 15:07, Benjamin M.

Re: [Server-devel] Backup and Recovery
Martin, Thanks for the confirmation. I am in the process of debugging. The only change that made it get that far was to the journalentrybundle.py file. Adding the get_bundle_id def (it just returns None btw) allowed it to go a step further and unzip the backup file. However, please see the new error I am getting below. It deflates the backup file but right after that it errors out complaining about a missing __zip_file. I noticed that it assumes the files extracted from the backup data is an ActivityBundle. Is that correct ? I'm tempted to just upgrade sugar to 0.86 but there might be those still using strawberry who are reluctant to upgrade but would like to get backup and restore working for strawberry, so finding exactly what to change/fix on strawberry might be useful. * Archive: /home/liveuser/.sugar/default/data/8419a696-5a24-4595-aeda-7488e72605fa inflating: /tmp/83366588-d84b-4f00-acc1-3e5f32525540/83366588-d84b-4f00-acc1-3e5f32525540 inflating: /tmp/83366588-d84b-4f00-acc1-3e5f32525540/_metadata.json caution: excluded filename not matched: mimetype sugar.bundle.activitybundle.ActivityBundle object at 0x9e7ad6c Traceback (most recent call last): File /usr/lib/python2.6/site-packages/dbus/connection.py, line 214, in maybe_handle_message self._handler(*args, **kwargs) File /usr/lib/python2.6/site-packages/jarabe/journal/model.py, line 377, in _datastore_updated_cb updated.send(None, object_id=object_id) File /usr/lib/python2.6/site-packages/sugar/dispatch/dispatcher.py, line 125, in send response = receiver(signal=self, sender=sender, **named) File /usr/lib/python2.6/site-packages/jarabe/journal/journalactivity.py, line 250, in __model_updated_cb self._check_for_bundle(kwargs['object_id']) File /usr/lib/python2.6/site-packages/jarabe/journal/journalactivity.py, line 283, in _check_for_bundle registry.install(bundle) File /usr/lib/python2.6/site-packages/jarabe/model/bundleregistry.py, line 344, in install elif not self.add_bundle(install_path): File /usr/lib/python2.6/site-packages/jarabe/model/bundleregistry.py, line 194, in add_bundle bundle = self._add_bundle(bundle_path) File /usr/lib/python2.6/site-packages/jarabe/model/bundleregistry.py, line 208, in _add_bundle bundle = ActivityBundle(bundle_path) File /usr/lib/python2.6/site-packages/sugar/bundle/activitybundle.py, line 51, in __init__ Bundle.__init__(self, path) File /usr/lib/python2.6/site-packages/sugar/bundle/bundle.py, line 65, in __init__ if os.path.isdir(self._path): File /usr/lib/python2.6/genericpath.py, line 41, in isdir st = os.stat(s) TypeError: coercing to Unicode: need string or buffer, NoneType found Exception AttributeError: 'ActivityBundle' object has no attribute '_zip_file' in bound method ActivityBundle.__del__ of sugar.bundle.activitybundle.Acti vityBundle object at 0x9e7ad6c ignored * On Mon, 2009-11-02 at 16:47 +0100, Martin Langhoff wrote: On Mon, Nov 2, 2009 at 4:43 AM, Hamilton Chua hamilton.c...@gmail.com wrote: I have backported the changes to the strawberry release and restore seems to be working now.
