Broken XO-1 battery (battery LED flashes red)

2010-03-11 Thread Philipp Kocher
Hi

The battery LED is flashing red and ec-abnormal@ . at the OFW (version 
Q2E41) prompt gives back the value c.

What does c mean? Can it be fixed?

Regards,
Philipp

2009-12-14 Thread Philipp Kocher

Keyboard/Mouse problem after resume:
- external USB keyboard works fine after resume

- I have attached an extract of the messages file with suspend, wait 5 
min, resume (suspend and resume with power button), but I don't know 
what could be related to keyboard/mouse.

smparrish will correct me if i'm wrong, but i believe the release
you're testing runs powerd, not ohmd.  the presence of the control
panel, and its inability to control powerd's behavior, is a bug,
or an unimplemented feature -- take your pick.

(you can disable powerd if you wish, with initctl stop powerd,
and move /etc/events.d/powerd elsewhere.  then start ohmd as you
did below.)

i'm curious about the keyboard/mouse not waking things up properly,
but i have zero time to look at it currently.

to prevent powerd from suspending the laptop, edit /etc/powerd/powerd.conf,
and adjust the timeout s to something big, like 9.

Hi Steven

- The scratch sensor board doesn't work (works with build 802)
   I hoped allow olpc access to ttyUSB nodes (from release notes os10) 
would make it work. I added an extract of /var/log/messages at the 
bottom of the email.

- timezone can not be changed in gnome since administration menu is 
missing (changing the timezone in sugar control panel has no effect in 
gnome). And talking about time, I think the clock activity is really 
nice and useful.

- build information OLPC release 11 (Leonidas) in sugar control panel 
is more confusing than helpful. What about 10 (based on Fedora 11)?

 Does it boot consistently into Sugar?  Gnome?
Worked fine here.
 Does sound work?
Yes,no problem.
 Can you suspend?  Does it wake up?
Suspend yes, but no proper wake up as mentioned by other testers
(but the shutdown with the power button is really nice and useful).

Re: Some testing notes for OS10 for the XO-1

2009-12-13 Thread Philipp Kocher
The Prolific driver gets loaded (see logs at the bottom).
The problem are the permissions.
After plugging in the scratch board ll /dev/ttyUSB0 shows:
crw-rw 1 root dialout 188, 0 2009-12-14 09:52 /dev/ttyUSB0

User olpc is not in group dialout which means it doesn't have access to 
ttyUSB0.

After adding olpc to group dialout the scratch board works fine.

Philipp

 Hi, Steven.

 The USB-serial cable that comes with the Scratch Sensor board needs a
 driver from Prolifix. That driver used to be included in the builds, but
 perhaps it was accidentally dropped?

 If you use a supported USB-serial adaptor cable, then I think the
 ScratchBoard will work.

 I just got a report that sound playback is rough on XO 1.5:

 http://dev.laptop.org/ticket/9375

 I'm guessing this is caused by a switch from ALSA to PulseAudio. We've
 seen that on Ubuntu; we still working to resolve the problem. PulseAudio
 itself has some buffering issues, although it appears that folks are
 working on those. The problems tend to show up more in applications
 where sounds are triggered dynamically, such as Scratch, EToys, and
 games, vs. playing music.

Is there a reason why 8.2.2 doesn't get signed by OLPC?
I do understand that the main target group are big deployments which can 
sign the build, but why are others excluded?

In the past even release candidates like build 800 got signed by OLPC.

Re: About 8.2.2

2009-12-01 Thread Philipp Kocher
Hi Ed, Martin

What is the plan for the Fedora 11 build for XO-1, will OLPC sign such a 
build or is 802 the last build signed by OLPC?

I don't think one of the two options is a good solution for small 
deployments without a tech team.

I think for the case of Cambodia with many small deployments 
(educational NGOs got XOs donated from G1G1/OLPC or other donors), no 
signed builds probably means that the XOs don't get updated anymore.

Best regards,
Philipp

 Philipp -

 An OS image signed by OLPC can be booted by any XO-1.0 laptop in the world, 
 except for those which have been reconfigured by a deployment to only respect 
 software signed by other security keys.  That implies a higher level of 
 testing and certification than an image that can be selectively adopted by 
 specific deployments who can do their own testing to decide whether that 
 release is suitable for their application.  As OLPC's deployments grow both 
 in number of total laptops deployed and in the number of different localities 
 supported, it becomes increasingly burdensome / difficult to package and test 
 One Image to Boot Them All worldwide.

 As Martin points out, we are continuing to try to move users toward either 
 (a) using machines with boot-image security disabled, so they can run any 
 software, or (b) using locally-developed and locally-maintained signature 
 authorities to sign OS images for secure boot in local deployments.

Fwd: Re: Importing images in Write documents makes file huge

2009-11-29 Thread Philipp Kocher
Bonjour Hubert

I read on planet.abisource.com (June 26, 2009) that you implemented the 
JPEG support for abiword 2.7.6. This feature would be very useful for 
OLPC XO laptops, but the newest release (8.2.1, build 802) for XOs 
includes still abiword 2.6.4.
Is it possible to make a small and low risk JPEG-patch for abiword 2.6.4 
so it could be included in release 8.2.2?

Work for a Fedora 11 based release (8.2.1 and 8.2.2 are based on Fedora 
9) is in progress. This release includes abiword 2.8.1, but it won't be 
stable enough to install it on student XOs soon (I am not aware of a 
schedule for this release).

Thanks,
Philipp

risk.

As Ben points out, this will imply a flag-day change. For people
controlling a whole deployment, this may very well be acceptable...
and the 8.2.x I am working on is focussed on deployments.

Importing images in Write documents makes file huge

2009-11-26 Thread Philipp Kocher
Hi all,

We would like the students to create simple html-documents with text and 
images and upload them to the schoolserver for a simple homepage. The 
Write activity (we are using version 60 on build 802) has a feature 
Keep as Hypertext (HTML), but when images are inserted into the 
document the files get huge (10 times bigger than original image).

If I check the file size in the datastore, an image created with Record 
(file size 38kB, mimetype image/jpg) inserted in a html document 
containing nothing else than the image, the html file is 554kB (mimetype 
text/html).

The image is saved in the html-document with:
img ... src=data:image/png;base64,{image data}

I can do the same thing with Abiword 2.8.1 and the html file is just 
52kB, probably because it is using jpg:
img ... src=data:image/jpeg;base64,{image data}

There is an old ticket for that (last modified 2 years ago):
Ticket #1442 non-PNG image support for Abiword

Any suggestions for a workaround? Is there an other activity we could 
use to create html pages?

Best regards,
Philipp

PS: other document types created with Write have the same problem:
image/jpg:   38kB (created with Record activity)
application/rtf:821kB (created with Write activity)
text/html:  554kB (created with Write activity)
application/vnd.oasis.opendocument.text: 406kB (created with Write

The conversion to PNG was a general Abiword feature, but it got solved 
last July with Abiword 2.7.6 (see link below).
On my XO libabiword-2.6.4-6.olpc3 is installed (build 802).

Is it possible to install an libabiword-olpc rpm of version 2.7.6 or newer?

Marc Maurer: Impressive AbiWord release
We just released AbiWord 2.7.6, which is an awesome release in my opinion!
It for example adds native JPEG support, so we don’t convert every JPEG 
internally to PNG anymore. This will be of great benefit on the OLPC 
laptop, where kids use built-in camera to produce photos in JPEG format 
and add them to their document. This will greatly reduce the filesize of 
their document. It will also be a lot less bandwidth intensive when 
collaborating on such a document.

 I guess it depends on how many technical resources you have, but it's
 definitely possible. Though maybe the best way forward is helping with
 the effort of making F11 work well on the XO-1s.

 http://wiki.laptop.org/go/F11_for_XO-1

What about 8.2.x?
At the moment the write activity is not really responsive when a few 
pictures are in the document. I expect that would improve as well.

It looks like abiword 2.8.1 is already part of F11 for XO 1, which 
should solve the problem. But I don't expect F11 being installed on the 
student XOs very soon, is there an alternative solution like another 
activity that can create simple html files with pictures?

[Server-devel] XS 0.6 on XO

2009-11-04 Thread Philipp Kocher

Really nice to have an XS on the XO for testing and showing people what
they can do with an XS.
The easy setup which doesn't even need an access point is really cool.

There are 3 points about XS 0.6 on XO I want to bring up:
1. How to shutdown the XS.
I couldn't find the information what is the easiest way to do it. I see
to easy options:
- Switching off power means the XS shuts down (I have attached an acmon
script a workmate wrote some time ago for a webserver on an XO which
does that using crontab)
- ctrl+alt+delete (on the XO delete is fn+erase) does a
reboot at the moment, but I think it could be easily changed to a more
useful shutdown.

2. How to change the timezone is missing in the documentation, but
probably necessary in most places.

3. Non XO computers can not connect to the school-mesh-0 of the XS on
XO. I wanted to do some testing and had just one XO (which was running
the XS). To be able to connect from a normal laptop I had to do the
following changes on the XS (the specific IP is important since various
services are bound to this IP):
ifdown lanbond0
iwconfig wmesh0 essid schoolserver
iwconfig wmesh0 mode ad-hoc
iwconfig wmesh0 channel 6
ifconfig wmesh0 172.18.0.1
Is there an easier way?

Cheers,
Philipp

sugar-install-bundle doesn't work with content bundles (build 802)

2009-09-27 Thread Philipp Kocher

Hi all,

For a deployment without a schoolserver I needed a script to install 
bundles (.xo and .xol) from a USB flash drive. I wanted to use the 
script for initial installation of bundles, installing upgrades and 
reinstall by mistake erased activities. I know the option with the 
customization.zip, but I don't want to reboot.


To call sugar-install-bundles in a script seemed to be a good solution:

for i in ${USB_BUNDLES_DIR}/*.xo*; do
sugar-install-bundle $i
done

But I faced to problems:
1. sugar-install-bundle doesn't support installing content/library bundles
2. sugar-install-bundle doesn't support upgrading from an old version of 
a bundle to a newer one


So I wrote a version of sugar-install-bundle that solves these two 
problems (see attachment).


It is slow, but it works.

Best regards,
Philipp

Re: Create and sign Country specific XO image

2009-06-29 Thread Philipp Kocher
The XOs got manufactured some time ago and just not delivered because
localization wasn't finished (localization is still not finished, but
the XO arrived yesterday).
So getting our own keys in the manufacturing data is not an option.

I hoped for an easier image creation and signing process. What is the
problem with the process described here
http://blog.olenepal.org/index.php/archives/183?

1. setup one XO the way you want it (I would use a script to do this)
2. delete a few files
3. create the image with save-nand at the ok prompt.
4. If I could send the CRC file of the image to OLPC and they would give
me a fs.zip in return, that would be great.

This way I could use the NandBlaster for the first installation and
would be much faster than installing os802.img from USB flash drive and
call the customization script on the flash drive on each XO.

 You'll have to script some of those customizations.
 
 The other option is to use pilgrim, which is what I think they do in

 for the non-activity customizations, but image builder is probably a bit
 easier to get started with.
 
 You have to decide if you want to sign your own builds, or if you want
 to get OLPC to do it (if they will do so).
 
 To do it yourself you have to generate your own public/private keys and
 somehow get those public keys to be present in the manufacturing data on
 all of your laptops. Full details here:
 http://wiki.laptop.org/go/Firmware_security#Multiple-Key_Support
 The bios-crypto code is what you will use to sign your images.

Re: XO boot problem

2009-03-11 Thread Philipp Kocher
Hi Daniel

Thanks for the input. The XO is booting fine after the firmware update.

I was looking for the bootfw.zip online, older released firmware
versions have the bootfw.zip in this directory:
http://dev.laptop.org/pub/firmware/q2e18/

But you are right, I can just copy the bootfw.zip from a working XO with 
build 767 installed.

The ticket 7607 got fixed with q2e12 so it shouldn't happen with build
767 (q2e18) anymore. But I got the information that 3 XOs with build 767 
had the same problem. They got fixed with a clean install, so no way for 
further diagnosis.

Philipp

 Hi,

 An other school in Cambodia has the problem that several XOs don't boot

 With a dignostic startup the following information is last shown on the

 OLPC C2, 256 MiB memory installed, S/N CSN75001163
 OpenFirmware CL1 Q2D16 Q2D

 Nothing happens anymore afterwards.

 The OFW hardware diagnostic is still working.
 After a clean install the XO works fine again but all the data is lost.

 Has anyone a solution for that problem or input for further diagnosis?
 
 This is a common problem seen by several deployments:
 http://dev.laptop.org/ticket/7607
 
 It is caused when machines are shut down improperly - i.e. the child
 holds the power button for 5secs to turn off the laptop, or all power
 sources are removed (i.e. battery + AC connected, no AC and battery
 runs to zero, etc), or if the XO hard-crashes and you are forced to
 shut down uncleanly.
 
 The solution is to upgrade firmware to e.g. q2e18.
 
 While the firmware update will solve the immediate problem where
 OpenFirmware crashes when minor corruption is encountered, unclean
 shutdowns will lead to file corruption causing more, probably
 less-obvious problems down the line.
 
 I wanted to recommend a firmware update, but the file bootfw.zip is
 missing in the directory for the newer firmware releases (e.g. q2e18 for
 build 767):
 http://wiki.laptop.org/go/Upgrading_firmware#Steps_to_upgrade_firmware
 
 It sounds like you are not using 767, or have customized it somehow.
 Official 767 already has q2e18 as /boot/bootfw.zip and if you boot
 with AC connected it will upgrade you to q2e18.
 Could you give the URL to the build that you are using?

 grader  with build 767, this build installed by  Elijah  at the 
 beginning of the school year, he is a  computer teacher there. And 
 these problem we met last month  but in different time. So as I told 
 you I have no solution, even I tried to ran the hardware test  the 
 result everything is okay, but when I re-boot it again the computer 
 play sound the same as normal (the sound when the XO start) but after 
 that very soon it changed quickly to white screen and the XO in the 
 meddle of the screen and nothing happen  even we wait about 1 or 2 
 hours it still the same.  Right now I  had erased everything and  put 
 the old build 708 back for them even we don't know what problem is 
 and I'm worry that it will be more computers have the same problem 
 like this and I don't want to erase the student's project from their 
 XO, if you can help with this problem it will be helpful.

 Again thank you for your help,

 Best regards,
 Channa

 Hi Channa

 I can try to help you with your XO boot problem if you give me some 
 more information.
 Please give me a detailed description of the problem.

 Here are some questions, but if you have more information which 
 might be relevant please add it.
 What is the build number?
 How many XOs are affected?
 When did it start?
 When did you install the new build?
 Brake all XOs at the same time?
 What do you see on the screen when the boot process stops?
 Can you do the hardware test?
 Are new XOs from the JHS affected as well?

 Philipp

Re: Journal integration for Scratch

2009-01-15 Thread Philipp Kocher
You are right. It doesn't work like that, but the filename is quite
important to me. It is shown in the Scratch GUI and it is an important
marker to find the project, when save and not save as is used.
I wouldn't just take the object_id. What do you think John?

There is a bug in Scratch version 12. The symbolic link of the Project
directory doesn't get created (Open Projects shows Scratch.activity
folder instead). I checked the scripts (scratch-activity and
scratch-wrapper) but couldn't find where the link should get created.

Philipp

 I would simply name the file $object_id.sb.

 Hi, Sugar will put it there for you when the .xo bundle is installed.
 That means that if the activity bundle gets installed from outside
 Sugar, the mime db won't be updated.
 
 So, I would recommend you to uninstall Scratch from Sugar, then
 installing the .xo bundle by downloading it with Browse or by copying
 it into the journal from an usb stick.
 
 HTH,
 
 Tomeu
 

Thanks for the input, but I wasn't successful.

I tried the following:
1. Extracted the files of Scratch-12.xo
2. Added the line mime_types = application/x-scratch-project to the 
activity.info file
2. Created a new archive file Scratch-12_mime.xo with the change
3. Erased activity Scratch on the XO
4. Copied the file Scratch-12_mime.xo to the Journal
5. Started/Installed Scratch-12_mime.xo
6. Copied Scratch project to the Journal with copy-to-journal test.sb 
-m 'application/x-scratch-project' -t test.sb

test.sb still has the standard icon and not the Scratch cat icon in the 
Journal.

Which activity is using the mime db update feature? I would expect a new 
timestamp for the file /usr/share/mime/mime.cache after installing the 
activity.
Can I execute the mime db update on the command line?

Re: XOs with no sound

Happy New Year.

We don't use the Measure Activity.
Here are the most frequently used Activities using sound:
- Scratch version 11 (with resume sound problem, ticket #6201)
- Record version 59
- Browse version 98 with Adobe flash plugin version 10.0.12.36 (gnash
deinstalled) for a flash based English learning program
- Gcompris bundle Version 10
- Speak version 9

Recording with Scratch works with No sound XOs even so Capture volume 
is set to 0.

I will keep an eye on the alsamixer when I use these activities.

 Okay, that must be a build 767 thing.  Recent development builds use
 /etc/asound.state only.  I've checked only the development builds at
 this stage.
 
 Master Mono Playback Switch: is false should be true (line 50)
 Master Mono Playback Volume: is 0 should be 28 (line 61)
 
 These two should have no effect.  I've tested that they have no effect
 on audio playback.  The method I used was to temporarily install the OSS
 module, and run a background process writing noise to the output.  Thus:
 
   modprobe snd-pcm-oss
   dd if=/dev/urandom of=/dev/dsp 
 
 While this is running I then manipulated the controls using alsamixer.
 The Master Mono Playback controls did nothing.
 
 (Incidentally, the volume control keys on the keyboard changed the
 Master control only, not the Master Mono control, and not the PCM
 control.)
 
 PCM Playback Switch: is false:false should be true:true (line 178)
 
 In false:false state, this switch prevents all sound output from
 activities and applications.  The noise test above fell silent.
 
 PCM Playback Volume: is 0:0 should be 22:22 (line 190)
 
 In 0:0 state, the audio is less loud, but not eliminated.  The noise
 test continued to generate audio, but I needed to set the Master control
 (not the Master Mono control) to at least 50%.
 
 Capture Volume: is 0:0 should be 15:15 (line 287)
 
 In this state, the noise test audio is unchanged.  This would affect
 sound capture using microphone though.
 
 I hope that helps.
 
 Yes, it does.  It shows the immediate cause of the problem was that the
 PCM Playback Switch was turned off.  That the Capture control was also
 changed is interesting.
 
 I've searched the installed activities on a development build here for
 references to the amixer command.  The only activity that I've found it
 used in is Measure.
 
 Measure.activity/toolbar_side.py ... changes the Capture control.
 
 Measure.activity/audiograb.py ... changes the PCM Playback Switch.
 
 Is Measure being used?  Can you reproduce the symptom on a working XO by
 asking for a shutdown while Measure is running?  What version of Measure
 is being used?
 
 Version 20 of Measure attempts to restore PCM to 70 on quit.  Does the
 symptom clear if Measure is started and then quit?

Alsa keeps the values in memory and writes it into the

Sorry my master asound.state file was working but not standard. I have

no sound XO

Master Mono Playback Switch: is false should be true (line 50)
Master Mono Playback Volume: is 0 should be 28 (line 61)
PCM Playback Switch: is false:false should be true:true (line 178)
PCM Playback Volume: is 0:0 should be 22:22 (line 190)

XOs with no sound

2008-12-30 Thread Philipp Kocher
Hi

The sound of 5 of our 100 XOs doesn't work anymore.
The hardware test is okay (sound works), but all the sugar activities I 
tested (Scratch, TamTamMini, Speak, Gcompris) don't have sound. 
Rebooting the XO doesn't help.

I checked the sugar log files and /var/log/messages, but couldn't find 
any sound related warnings or errors.

We are running build 767, but I have seen the same problem with build 
708 (but not that often).
Reinstalling the OS solves the problem, but I would prefer an easier 
solution.

I checked if such a bug is reported, but couldn't find a ticket (the 
sound resume problem of ticket 6201 is normally solved with a reboot). 
Since I don't know how to reproduce the problem, I would like to 
localize it before opening a ticket.
What can I do to localize the problem (e.g. low level sound tests)?

Is it possible that running out of battery while playing sound can have 
such an effect or could it be related to the resume problem of ticket 
6201 (we had that problem very often with Scratch when the experimental 
power management was switched on )?

What is the ticket number for that problem?

It seems like always the same 7 values are wrong.

There is a shorter solution:
1. Copy /etc/alsa/asound.state of a healthy XO to USB flash drive
2. Type alsactl -f /media/{flash_dirve_name}/asound.state restore on 
the XO with no sound

 1.  obtain the root prompt, e.g. by starting the Terminal activity and

 2.  if you wish to find out in which way the settings have been
 corrupted, copy the file /etc/asound.state before proceeding,

Re: Journal integration for Scratch

2008-12-25 Thread Philipp Kocher
Hi John

Sorry for the late response.

I think to increase the font size in the file dialog is a good idea. As
for the thumbnails and project notes, for us an easy way to open and
save the projects is more important than to see a thumbnail and project
notes (the filename and the date when the project was saved is enough
information for us).

If the examples and the own projects would be separated (e.g. a button
examples) would help as well. It is quite confusing for the students
that they can not save their projects in some folders (folder symbols of
own folders and example folders look the same, but no write permission
for the example folders). TurtleArt has such a solution.

Scratch is the favourite Activity at our school, even so it is quite
hard for the students to drag and drop the small command icons on the XO
with the jumping mouse cursor problem.

I am aware that these are all just XO problems and you have to maintain
other platforms as well. Thanks for your great support for Scratch on
the XO.

Thanks,

 Probably not in the near future. There has been talk about making an API 
 for the Journal that looks more like a file system to application 
 programs. That might be the easiest way to integrate the Journal into 
 Scratch in the long run.
 
 Sugar continues to evolve. Earlier versions still allowed access to the 
 file system in a way that made it fairly easy to port applications like 
 Scratch. More recently, with the Rainbow security system, it became much 
 more difficult to use the file system directly.
 
 I support Scratch on many different platforms. The XO is an important 
 one due to the educational mission of OLPC. Still, my time is limited 
 and I can only spend so much of it on the XO version of Scratch. Thus, I 
 try to steer a middle path -- create a Scratch port for the XO without 
 changing too much of the Scratch source code. I am hoping that 
 eventually Sugar will make life easier for those porting applications 
 from file-based platforms by providing some sort of virtual file system 
 API. The Journal and the virtual file system could just be two views on 
 the same set of files.

 Yes, I see the problem. Your solution sounds like it would work, but the 
 downside is that browsing for existing Scratch projects would be done 
 using the Journal, rather than Scratch's open dialog. That means the 
 user would not see the project thumbnail and project notes.
 
 If project deletion is the only issue, my preference would be to add a 
 way to delete projects to the Scratch open and save dialogs. (Although 
 I'm not promising to do that immediately, since we're currently working 
 on the release of Scratch 1.4.)
 
 Another solution (which could be more near-term) would be to increase 
 the font size in the file dialog. Do you think that would help?

Re: Downloading Scratch project to XO

2008-12-17 Thread Philipp Kocher
Hi Bert, John

There is a bug in copy-from-journal, it is adding an additional dot 
before the file extension. Otherwise it is working.

[o...@localhost ~]$ copy-from-journal -o 
07474cf4-4883-4ded-a994-ab5511cfc29c /tmp/test.sb
/home/olpc/.sugar/default/data/07474cf4-4883-4ded-a994-ab5511cfc29c - 
/tmp/test..sb

My workaround in scratch-activity looks like this:
if [ -n $object_id ] ; then
filename=$SUGAR_ACTIVITY_ROOT/instance/temp.sb
copy-from-journal -o $object_id $filename
filename=$SUGAR_ACTIVITY_ROOT/instance/temp..sb
else
filename=
fi
# run Squeak VM with Scratch image
exec /usr/bin/squeak \
-vm-display-X11 \
-swapbtn \
-sugarBundleId $bundle_id \
-sugarActivityId $activity_id \
ScratchXO.image \
$filename

 (assuming the Scratch wrapper still basically looks like the Etoys one)

 Hi, Bert.

 Thanks for the help on this.

 To clarify, what I was doing was using the clipboard to move a 
 downloaded Scratch project file. I dragged it from the Journal to the 
 clipboard, then went to the Scratch activity and dropped it onto the 
 Scratch window. So that's a somewhat different path from trying to 
 open the project directly in the Journal. It would be great to get 
 both paths working eventually.

 Re: But this retrieval could be done in the Scratch wrapper script.

 Cool! That would be an easy solution for me if the wrapper script is 
 not too complex. Could you give me a hint about what the wrapper 
 script would look like?

 Meanwhile, I will try to make the drag-n-drop-from-clipboard solution 
 work.

 Not quite, Sugar will not actually pass the file name of the Journal 
 entry when launching the activity. Instead, it passes the id of a 
 datastore object, and the activity is supposed to retrieve that from 
 the datastore. But this retrieval could be done in the Scratch 
 wrapper script.

 Hi, Bert.

 Re: does Scratch accept a .sb file on its command line?

 Yes, it does.

 The problem is that the journal is changing the file extension to 
 something like .bin, and Scratch doesn't think a .bin file is a 
 Scratch project file and simply ignores it.

 I believe the issue is just that we need one extra file in the 
 Scratch activity info to tells the Journal that Scratch handles the 
 file extensions .sb and .sprite. I figured out what that file should 
 have in it a few weeks back but haven't yet had a chance to try it.

 I'll give it a try and, if it works, I'll release a new version of 
 Scratch on the XO that includes that file.

 John,

 If so, the launcher script could get the file from the Journal and 
 pass it on.

 Hi, Phillipp.

 Thanks for reporting this problem. I believe there is a way to tell
 the XO to associate the .sb file extension with Scratch. I will look
 into that and let you know if I figure it out.

 Hi

 I would like to download Scratch projects from a local server to the

 On the server I added the following line to the file 
 /etc/mime.types:
 application/scratch sb

 The apache server is now sending files with sb-extension with mime
 type application/scratch.

 On the XO the mime type gets stored in the datastore metadata-file.
 After adding the following line to the Scratch activity/
 activity.info file, Scratch gets started when clicking on the
 Scratch project in the Journal:
 mime_types = application/scratch

 The problem is that the project doesn't get opened. The scratch
 start script bin/scratch-activity gets called with the -u argument
 holding a datastore object ID, but the script doesn't handle the -u
 argument.

 How can I convert a datastore object ID to a filename, so scratch
 can open the project? And how do I get the necessary permissions to
 access the file?

Journal integration for Scratch

2008-12-17 Thread Philipp Kocher
Hi John

Do you plan a journal integration for scratch?

At the moment it is not possible to delete scratch projects easily (just 
in terminal) and our students have difficulty to understand the file and 
folder structure in the dialog with the very small font.

If you don't want to change the core application, there might be a 
workaround.

1. create a directory projects/journal
2. if scratch gets opened without a datastore reference, a default 
project (e.g. scratch_project) gets copied to projects/journal and opened.
3. if scratch gets opened with a datastore reference, the files gets 
copied (copy-from-journal) to the projects/journal directory and opened.
4. the name of the default project still has to be changed with save as
5. after quit the files in the directory projects/journal get copied to 
the journal (copy-to-journal) and deleted in projects/journal

The scratch projects could be erased in the journal.
What do you think?

One more thing, the scratch icon is not shown in the journal for files 
with the scratch mimetype. I think the file 
/usr/share/sugar/data/mime.defaults has to be adapted to include the 
scratch-mimetype.

Best regards,
Philipp

Downloading Scratch project to XO

[Server-devel] Wikiserver on XS

2008-06-26 Thread Philipp Kocher
Hi,

Is there a wikiserver installed on the XS?
Apart from this old page http://wiki.laptop.org/go/Trial1_Server_Software, I 
can not find any hints.
If yes, is it moinmoin, mediawiki or maybe the wiki-plugin for moodle?

I have to write some documentation and I want to make sure that I 
install the right product. Makes it easier to transfer the data to the 
XS later.

Thanks and best regards,
