Totally, and there's also a big win in redesigning half of the XO's
hardware and the linux kernel so that we get the promised suspend
resume experience.

Can now get back to work we can actually get done?

RE: Music Keyboard for TamTam?

[Caryl Bigenho]

Hi Gary,



This is very exciting and I would love to help test it when it is ready
for that.  This idea came to mind when I noticed Mexico's OLPC activity
information for TamTamMini showed the relationship of the XO keys to those
of an actual music keyboard. Why not let the children experience the real 
thing? You can download their guide here (see page 3 in the TamTamMini 
instructions):

http://www.mochiladigitaltelmex.com.mx/olpc/index.php/Herramientas_pedag%C3%B3gicas



As a former music major and the wife of a retired instrumental music
teacher, I really would love to have TamTam give students a chance to
transfer their skills to music keyboards and mallet instruments.  I
asked on the olpc-sur list if anyone would use something like this with
their students.  I got only one reply, but I think it was evidence of
the concerns teachers have...they thought it was a great idea except for
the cost of the music keyboards.



Maybe we need to start a company to make no-frills basic usb music
keyboards to sell for about $20-$25 US so that schools in countries
with deployments could afford to get some for their music classes.



Keep me posted on your progress!

mock.laptop.org repos repo

[Ties Stuij]

Hey,

I'm making a local pilgrim and I'd like to have the repo at
mock.laptop.org, which contains all rpms for the different xo builds.
Git doesn't work however because I get out of memory errors, so I want
to rsync it or find some other way or repository. Is it perhaps
mirrored on dev.laptop.org (it's not in the projects listin in any
case)? Or is there another way of getting to it?

I see that the tickets for 8.2.1 seem to be all labeled for the 9.1

Tickets 8976, 8745, 9044, 9045, 8982, 8155, 8767, and 8451 should all be
tagged as for the 8.2.1 release, and those are the ONLY tickets that should
be so labeled.  These are the high-priority items we need to be working on
right now to get this minor release ready ASAP.  Thanks!

How do I do the strace for activity startup ? In an XO, it's pretty
easy to do via rainbow, but how do I do this in sugar-jhbuild ?
There's a MOZ_PLUGIN_PATH which looks promising, but somehow it's not
working for me. Strace should be able provide clues.

Thanks,
Sayamindu

 What are the binaries, libraries and other resources that are needed
 by the evince plugin and aren't available on the 8.2.0 image?

You can strace an activity easily if you launch it from Terminal.
Otherwise you will need to hack the sugar sources.

strace -f sugar-launch Web

should work, I think.

I don't know if Browse uses MOZ_PLUGIN_PATH, but the Firefox activity 
definitely does, see
http://wiki.laptop.org/go/Talk:Firefox#Workaround_to_share_Browse_plug-ins

The system plug-ins directory for both Browse and Firefox is 
/usr/lib/mozilla/plugins but I'm sure they check other directories with 
or without MOZ_PLUGIN_PATH set.

[PATCH] cafe_nand: remove busy-wait loop

[Daniel Drake]

This patch enables interrupts for DMA and command completion events, and
uses them to determine when commands and transfers have completed.

This avoids a busy-wait loop which was a waste of CPU time.

Signed-off-by: Daniel Drake <[EMAIL PROTECTED]>

---
Where do we go with this? Who's adventurous enough to test it? Dare we
put it in joyride? Any suggestions for how to measure performance
difference?

It works for me.

[Server-devel] Bonding regression on 2.6.27

[Martin Langhoff]

Hi Jesper,

about a month ago you reported in lkml and netdev a (perhaps timing)
bug with bonding. The msg is
http://kerneltrap.org/mailarchive/linux-kernel/2008/11/16/4161864

Did you manage to resolve it or workaround it? Some users of the OLPC
School Server seem to be having a similar problem, and we're trying to
diagnose and resolve it...

thanks!

Re: [PATCH] cafe_nand: remove busy-wait loop

[Mitch Bradley]

Nice!

One quick test, for starters, is to do some file accesses to large files 
(dd or tar or whatever) and use the "time" command to look at the system 
and user times.  With the patch, the system time should drop to a 
fraction of the real time.

Start python script into terminal

[Rodolfo Pilas]

Hello:

I wish to start a python script into terminal.  I would like to create a
program with its own sugar-icon and terminal+script, something like:

exec = sugar-activity terminal.TerminalActivity -x SysOX.py

where -x is the way to explain terminal that I need to run a scipt.

It is possible to do with xterm:

$ xterm -e Activities/SysOX.activity/SysOX.py

but, unfortunatly xterm do not support font resize (-fs) parameter and
the default font is very very small.

Thank you for your suggestion.

Wow! This should apply as well to writes?

I reported some time ago that downloads from the LAN were limited by
cpu time, but I think to remember that it was due to the
autocompression.

In principle, for longish writes the compression of the next chunk could 
be overlapped with the write-back of the current chunk.  It will be 
interesting to see if that actually occurs, or if additional work is 
needed to unlock the potential parallelism.

At any rate, even for short writes, the userland program should be able 
to get the CPU back as soon as the write to NAND is initiated, thus 
saving 100 usec of otherwise-wasted time.

One way to do this, I think, would be to make a Pippy program that runs

Re: [Sugar-devel] Wacom Bamboo with XO?

[Stanley Sokolow]

I tried the new installation instructions on the wiki, first installing the
Colors activity, then running the new shell script as per the wiki:

wget http://dev.laptop.org/~wadeb/setupwacom.sh
sudo sh setupwacom.sh

It seemed to run ok without errors.  I restarted the XO.  Colors installed
ok and works with the mouse, but the Wacom Bamboo tablet does not work,
neither in Colors nor anywhere else.   Looking at the /dev/input directory,
I don't see the wacom device that should be there.   When I rerun the shell
script, it confirms that the linuxwacom package is already installed.The
X11 configuration file contains the Wacom devices, so it's the right conf
file.   I'm stuck.

Has anyone had success with the new instructions?

By the way, when I tried the old instructions yesterday, the repomd.xml file
was corrupted.   (Actually, it was a perl script, not an xml file.)  So, yum
wouldn't run.  Someone apparently fixed that problem.It's an xml file
now and yum seems to run ok using it.

 We won't use the evince plugin (as it does not have Journal support).

Are you sure?  Browse makes use of shared code, but still presents the

the request here to prevent instances entirely goes against the Sugar
HIG, but I might be misunderstanding.

Pablo, for what reasons do you desire to prevent multiple instances
from running?

8.2.1 test plan finalized (next: test cases need finalization)

[Mel Chua]

(The intent of this email is to make "what's going on with 8.2.1 
testing" as transparent as possible.)

I checked after the 8am work estimate cutoff, and made sure that the 
test plan matched up with the trac tickets listed at [[Eco/8.2.1]] - as 
of right now, it does. (Sweet!)

I believe that means that we can consider the list of test cases here as 
final (Joe/Kim, please holler if I'm incorrect): 
http://wiki.laptop.org/go/Test_cases_8.2.1 (Note that this doesn't mean 
the test cases themselves are final - they're very rough! It does, 
however, mean that these test cases are the ones that will exist.)

I'll talk with the developers assigned to these 9 tickets and make sure 
that we have final test cases (or at least a plan for how to develop 
one) before Thursday's test community meeting, and see how close we can 
come to getting work estimates for each test case that's finalized.

Help on this would be quite welcome; catch me on IRC (#olpc, freenode,

the job (there's no reason this should be a Mel-specific task).

Activity Set for 9.1.0

[Greg Smith]

Hi All,

Learning from the last release, I want to start activity selection early 
for 9.1.0.

I created a section on the 9.1.0 planning page for activities: 
http://wiki.laptop.org/go/9.1.0_requirements#Activities

I want to get all potential activities listed there. An activity will 
need to be tested with the release and have a maintainer to have a 
chance for inclusion. Like last time, we will gather input from everyone 
then make a decision on the final set. OLPC management gets the final 
say but I will make sure they hear the voice of the community, 
preferably consensus.

You can help by updating that Wiki page with the details of the 
activities you think should be included.

Personally, I would like to see a few fun (but not violent) activities. 
Something colorful, exciting and fun for kids. My kids recently started 
playing with Spore demos. I'm not asking for something that pretty, but 
a few really fun looking and addictive applications for kids would be great!

Morgan,

What can we do to fire up the activity community (and list) again?

Can you make sure we have the full list of contacts you gathered from 
the last round? We can also cook up an invite e-mail to get people 
thinking about 9.1.0 once we have a contact list.

Target is to have tested, working activities to choose from by the end 
of February.

Any comments or questions welcome.

Thanks,

Greg S

Right.

The way to do it would be to create a unique D-Bus service in your  
activity. When the second instance tries to create that service it  
will notice that it already exists. It could then notify its first  
instance via said D-Bus service.

Hi Greg,

Our software releases don't ship with activities, so I don't understand
what's being selected here.  We didn't choose a set of activities to
ship with 8.2.0; we chose a set of activities to ship on a G1G1 image.
Each deployment creates its own conjunction of {XO release+Activities},
with G1G1 being one such deployment when it's running.

Could you elaborate on what the list of chosen activities would mean
this time around?

Hi Chris,

When this release is done we will update the default image used in 
manufacturing.

All of our deployments except one currently take the default image. Many 
change it (usually adding more than subtracting) after they get the XOs 
in country but they start with our "factory" image.

We will also offer people an option to clean install with a set of 
activities like we did in 8.2.

Let me know if that's not clear or you need more info.

Wine activity

[Vincent Povirk]

The Wine activity has advanced to the point where I think it's ready
for testing by actual users.

The current package, development history, and my todo list are at
http://wiki.winehq.org/SugaredWine

The intent of this project is to provide a shell that can be used to
run Windows programs using Wine in the Sugar environment. It should be
good enough that someone used to Windows can grab and install a
Windows program without help, once the activity is installed. Ideally,
the installer and software will both work fine in Wine and within the
hardware limitations of an XO. In this ideal case, someone used to
Windows should be able to operate it without help.

If it does not live up to this ideal for platinum software (according
to the Wine appdb) whose hardware requirements the XO meets, I want to
know about it and hopefully fix it.

Wine bugs and hardware limitations mean a lot of Windows programs
won't work or won't work properly. On Linux, one can often push the
compatibility much further than what works "out of the box" by looking
at console messages (the log viewer works for this) and tweaking Wine.
Don't expect everything to work perfectly, but don't give up if it
doesn't. This is normal, even on Linux.

Winehq.org has support channels for such cases (appdb, bugzilla,
mailing lists, and the winehq irc channel). Most of the people there
probably don't know anything about Sugared Wine, but collectively they
should know more than I do about making Wine work in general. If a
program doesn't work for you, you can go to any of those places for
support. You can also email [EMAIL PROTECTED] That goes
directly to me for now, but in the future (maybe the very near future)
I may decide to send it somewhere public, like a mailing list,
instead.

Wine and the code that I developed for this project are licensed under
the GNU LGPL. The entire package isn't quite LGPL because I included
7-zip. 7-zip is LGPL + unRAR restriction (you're not allowed to use
the source code to create a RAR compressor).

If you have a program that works well in this Wine package and would
like to package it as a stand-alone .xo, please let me know. I already
did most of the work for this so that I could include 7-zip and a
firefox downloader/installer (and I could probably have included
firefox itself if not for the fact that it would require uploading
non-open-source code to repo.or.cz).

The system time does drop considerably, but unfortunately the transfer
rate also decreases significantly. I think this is because many of the
commands execute very quickly (1-10us), therefore it is wasteful to go
and schedule a new process only to come back immediately after.
Perhaps we can come up with a scheme that does a fast busy-loop for
the quick commands, and then schedules for the longer ones.

Here are the results anyway. Both experiments running on joyride-2579,
jffs2 filesystem, and a 50mb "randfile" that I generated on another
computer from /dev/urandom

First experiment was "echo 3 > /proc/sys/vm/drop_caches; time dd
if=randfile of=/dev/null"
that is, reading the file from the NAND, with caches cold. Repeated 3 times.

Before:
52428800 bytes (52 MB) copied, 5.4499 s, 9.6 MB/s
real0m7.324s
sys 0m7.080s

52428800 bytes (52 MB) copied, 5.38514 s, 9.7 MB/s
real0m5.452s
sys 0m5.190s

52428800 bytes (52 MB) copied, 5.41167 s, 9.7 MB/s
real0m5.480s
sys 0m5.210s



After:
52428800 bytes (52 MB) copied, 10.2002 s, 5.1 MB/s
real0m24.593s
sys 0m2.310s

52428800 bytes (52 MB) copied, 10.166 s, 5.2 MB/s
real0m10.266s
sys 0m0.910s

52428800 bytes (52 MB) copied, 9.72464 s, 5.4 MB/s
real0m9.840s
sys 0m1.210s

So, the transfer rate dropped from about 9.6mb/sec to about 5.3mb/sec.
However, sys time decreased by a factor of about 5. Also note that the
first run in each case took significantly longer (especially in the
after case, perhaps an anomaly) presumably because it had to load 'dd'
from nand too.



Second experiment: duplicate the file on disk, with hot caches so that
we are measuring write (and not also read).
"rm copy; cat randfile > /dev/null; time cp randfile copy" repeated 3 times

Before:
real0m56.459s
sys 0m51.280s

real0m57.919s
sys 0m51.300s

real0m56.016s
sys 0m50.970s

After:
real1m36.600s
sys 0m7.480s

real1m19.303s

Again, a considerable increase in real time, and a considerable

I'll try and find some time to identify which commands are the ones

for those ones.

Re: Wine activity

[Ixo X oxI]

Awesome,   I did some quickie work on Wine on the XO last year..
   http://wiki.laptop.org/go/Wine

:)  hoping that some day, someone would pickup the ball and run with it!

I'll definitely test out the new Activity and offer some feedback, the next
chance I get!

-iXo
p.s. for extra excitement, install Google's Picasa for Linux (which includes
Wine!)  slow... slow.. but it works !  :)

performance work (was re: Re: Sugar & XFCE)

[Greg Smith]

Hi Neil,

I couldn't resist replying after I saw your reference to Geoworks. I've 
never seen any other references to that elegant "shell"!

In terms of performance, unfortunately its not one of the top four items 
for release 9.1.0. That said it is a pet peeve of mine and a serious 
concern for deployments. I want to make some progress in 9.1.0 if we can.

Three ideas on how you can help.

1 - There is a recent thread on SVG performance. See: 
http://lists.sugarlabs.org/archive/sugar-devel/2008-December/010200.html

You may find something there you can contribute to.

2 - I also get the impression we do need to work on the Cairo front. If 
you can list a set of bugs, we can flag them as useful for 9.1 and track 
them.

3 - John's list of suggestions looks helpful too.

I put forward a basic requirements definition on performance here:
http://wiki.laptop.org/go/Feature_roadmap#Performance

That page is locked briefly while I move it to Semantic Wiki format. 
That should be done by Friday.

Starting next week, anyone can update the specifications section with 
URLs to code or design suggestions and other work. That should help us 
get synchronized and moving in the same direction.

Comments on the requirements welcome too. Considering that everyone 
knows the GUI is "slow" it was surprisingly hard to write!

You want to help and we need your help. Let me know what I can do to 
make it happen.

Thanks,

Greg S

That doesn't change the fact that using the XO is like walking neck deep
in treacle.

I absolutely agree that the machine is up to doing good performance.  It
dismays me to see things like the scrolling of a static web page in
browse can't keep up with keypresses.  The real problem there is it's
hard to isolate the slowness, I think largely due to the fact that the
problems aren't isolated.

Is there any central repository for information about where the speed is
going?

I'd like to help out here, and I've tried, but it has been very
difficult.  When looking at things I have encountered things like "Why
don't you use [thing], that should do it the best way" only to find
[thing] needs help from an experienced [thing] hacker to work
efficiently in this case.

Much of the time [thing] has been cairo or X. but I think that's only
because of the areas I've tried to work.

I'm still reminded of using GEOworks Ensemble on a 286. It could do so
much with so little and the XO seems to do so little with so much more.

Not blaming anyone in particular, but I've been trying to work on this
stuff and I have to vent my frustration every six months or so.

Way to tell if it is an XO

[Marcel Renaud]

Hello,

I need to know what is a good way to find out if the local machine running a
python script is a XO.
The goal is to check it the machine running the program is in fact an XO or
some other machine, and to do it in a way that is very hard to fake from
some other computer.

Any help is greatly appreciated.

Regards,

Marcel

Do stuff placed in $SUGAR_ACTIVITY_ROOT remain persistent across

Hi Marcel,

One way might be to "cat /ofw/model".  If the file doesn't exist, or
doesn't return a letter and number, you probably aren't running on an
XO.

   > The goal is to check it the machine running the program is in fact

I don't think making this hard to fake is possible, because any computer
with root access can reply to your test in whatever way is necessary.
I think you probably shouldn't try to accomplish this, or should try to
use a different method such as a pre-shared credential.

Hope that helps,

- Chris.

I think upgrading to a newer version of git will solve the memory
errors?  That was something that happened often with debian/stable-era
git.

If you've looked at the pilgrim repo, you'll have noticed that we
export via http (w/ gitweb) as well.  There's a snapshot link at
   http://mock.laptop.org/gitweb/?p=repos;a=summary
and the individual packages are available via http as well.

Yes, regardless of which test Marcel implements, it should be easy to
fool the test in a few minutes.

You misunderstood. Why copy at all? Why not run it from the bundle?

Copying from the bundle is only necessary for e.g. default  
configuration files that the activity needs to be able to change later  
(because the bundle itself is read-only).

I reinstalled fresh and, after the usual setup stuff, compiled and installed
2.6.26.8 according to these instructions:

http://www.howtoforge.com/kernel_compilation_fedora_p2

So now I've got this:

[EMAIL PROTECTED] ~]# uname -a

In the messages, I saw it was complaining it didn't know how to bring up
bonding.  So, per Jerry's earlier suggestion, I edited
/etc/modprobe.d/xs_bonding with this:

options mshbond0 mode=active-backup miimon=100
options mshbond1 mode=active-backup miimon=100
options mshbond2 mode=active-backup miimon=100

But after a reboot, this is in /var/log/messages:

I have an AP set to 172.18.96.5 plugged into eth1, but can't ping it.  The

you don't need to use D-Bus for this, it can be done by X without any 
other communication channels.

I don't know the details for how to do this, but I've seen mozilla/firefox 
do this for a few years. to see this start firefox on one machine, connect 
to another machine and point the display back to the first one. then try 
and start firefox on that second machine. the end result will be a new 
window opening up, but running on the first machine (if you have trouble 
seeing the difference, make the two machines have different bookmarks, or 
give one network access that the other doesn't have)

please don't develop new mechanisms to do things that already exist.

Re: 8.2.1 test plan finalized (next: test cases need finalization)

[Kimberley Quirk]

Mel,
We need to include all the smoke tests, which should be run on any  
build to ensure that the basic functionality of the build has been  
retained.

Also, we should review other test cases that might help reveal a  
regression... for instance, if we mess with wireless drivers, we need  
to do some more thorough wireless testing -- connecting to various  
access points, perhaps doing a 50 laptop test to a school server, ...  
in reviewing the bugs that are being fixed, we need to think about  
other areas that might be affected.

Let's plan on a review of the test cases with people who understand  
the bug fixes so we can brainstorm a bit on the test coverage.

Do you want to call that meeting? Probably Friday or later so we have  
the complete list of bug fixes that are going into the release.

Kim
