 You should see gabble listed and not salut

 If you only see salut you are not connected to ejabberd

Re: Wacom Bamboo with XO?

2008-11-17 Thread [EMAIL PROTECTED]
Paul,

Are you using the driver code from http://linuxwacom.sourceforge.net/  ?
I had intended on trying this but have been too busy to get the time   
set up the correct environment or follow all the steps involved for  
the initial setup
http://linuxwacom.sourceforge.net/index.php/doc

If you get something you think is workable let me know and I can test  
it with one of my Wacom Intuos 2 tablets.

Note there is also a mouse as well as a pen with this tablet so the  
mouse code needs to be compiled as well.

thanks for all the good work!!

Re: The XO laptop gets a Windows makeover

2008-10-26 Thread [EMAIL PROTECTED]
Albert,

I was not shouting down criticism. I was pointing out the inherent  
fallacy of the experiment.

File sharing is not an active real time collaboration tool by any  
means.   In sugar multiple children can work on the same write  
document, paint document, etc. at the same time and a copy is saved  
locally.  You are making the  fallacy of comparing apples with oranges.
As for Windows file sharing I could show you situations in which  
Windows file sharing fails miserably and  contrary to what you state  
Windows file sharing is not compatible between all operating  
systems.  A few of your statements are so bizarre they don't even  
deserve a response.

In my work life I use multiple OS in a given day and see these  
compatibility problems first hand.

Means of file sharing can be setup fairly easily in Sugar if you want  
to move raw files around. Currently file sharing is performed through  
activity sharing.

Just because MS Excel is used by some for science, engineering and  
statistics does not mean it is the correct tool for the job.  There  
are too  many serious problems with MS Excel that have never been  
fixed and have caused serious problems with a number of scientific  
projects, etc., that relied on MS Excel.  I too can use a screw  
driver to hammer a nail into a wall but does not mean it is the  
correct tool.

I agree with you that there has been a dearth of decent educational  
software on all platforms.  There is a chance to start a fresh with a  
new platform that is not encumbered with a legacy of poor offerings  
in that area.  Is that not what the stated target for the XO and  
Sugar is to be an educational tool?

Unfortunately from your response ,you have demonstrated you really do  
not understand the difference between education and rote learning.
By the way I did not say rote training was useless. I said it leads  
to inflexibility.
Rote learning is not based on understanding.

 Sugar isn't helped when people shout down any criticism.
 Living in denial about the competition just leads to failure.
 I'm far from a fan of Windows, but it gets many things right.

 If you think booting both into Sugar would have helped Sugar,
 then you obviously haven't seen the collaboration capabilities
 of Windows. Booting both into Windows would allow file sharing.
 Compared to what Sugar does, file sharing is very reliable.
 It works with **all** programs, without any developer effort.
 It's compatible between different software versions, different
 types of software, and even different OSes. It even eliminates
 the need to maintain a continuous network connection, which is
 great for kids without wired networks or reliable electricity.

 Windows is pointless as an educational platform.  I have never seen
 what I would call an educational application on Windows.  I have seen
 rote training applications on Windows.  About all Windows is good for
 is in a school training the next generation of low skilled, low wage
 support personal for Microsoft with out of date knowledge.

 I haven't seen decent educational software for any platform.
 That includes Sugar and Mac OS. Probably this means that the
 concept itself is defective. Real tools are superior.

 I have seen Microsoft Excel used for science, engineering, and
 statistics. Sugar has nothing comparable, despite at least two
 usable free spreadsheets being available for Linux.

 Remember education and training are 2 different concepts.  Education
 gives you the ability to reach beyond your base knowledge and to
 continue to learn, explore and synthesize ideas and concepts. Rote
 training freezes you in time and makes you inflexible.

 You just keep telling yourself that Windows is only for rote training
 (false) and that rote training is useless (also false) while the
 world mysteriously ignores you for some reason.

 Very doubtful.. this Gnash release is several weeks too late to meet

 My suggestion would be to find websites that work better in Gnash

 http://wiki.laptop.org/go/8.2.1

 It wouldn't hurt for you to include this snapshot in your release

 doesn't play YouTube.  Unless we find a strong reason not to,  
 we'll do
 a release tomorrow (about 28 hours from now).

 I don't think we will play YouTube, regardless of whether 0.8.3 or
 0.8.4 is shipped in 8.2.x. We don't ship the youtube-required
 proprietary codecs.
Btu end users could install them and have them work if gnash 0.8.4

 If end-users have to drop to a command line and do something, which I

 like you to offer a package for gnash 0.8.4 for them to install at the

You really do not get it do you!!  The basic functionality should be  
provided by OLPC with a build of gnash optimized for the Geode.
There has been demand for this from deployments and you have ignored  
this fact.
G1G1 users have been wanting this for a long time.  The new G1G1 V2   
users are going to be annoyed with this lack of support.
An additional data point is that Adobes flash support on Linux is not

Re: [Health] VideoChat is working now - hooray!

I agree that low cost , low tech, open source e-health/telehealth apps is the 
best way to go  in remote areas of the world as written about and demonstrated 
by Paul's partner in crime over at Partners Health Care, Dr Joe Kvedar. In 
those settings the above is ideal, but I can also make a case for a more 
powerful platform at the major medical centers or hubs. One of the problems in 
the US and to lesser extent the rest of the world, is that the vendors of 
telehealth/e-health are pushing te high end eqiupment and apps and thats part 
of the disconnect in what we really want to do , i.e provide low cost 
telehealth solutions to the world.

I think its very exciting to see telemedicne applications being developed for 
this platform. But I also think you need to be very careful here.  There are 
multiple studies on resolutuion of images and utility for various telemedicine 
purposes. (ie Still images from a 2 megapixel camera are likely mimimal for 
wound care, follow up, etc.)  In that scenario, video at 1 or 2 fps wouldnt be 
very good for assessing wounds. I think Bob is on target when it comes to the 
value add of video when it comes to doing evidence-based telemedicine.  

For example, if you are assessing a movement disorder, or trying to assess 
non-verbal cues in a psych patient, this will not be possible at 1-2fps.  It 
certainly adds a 'gee whiz factor to see the doctor from the patient's 
perspective, but the value to the doctor in terms of diagnosis will be minimal 
in my opinion.

That being said, the challenge is to find low bandwidth applications that make 
sense for patients and health workers and I think this will be very 
case-specific. Cudos to those seeking to develop them!

I think this is a misunderstanding.

We are not talking about robotic remote surgery here, or anything
requiring low-latency feedback.  Telehealth in this context refers to an
interview between a patient and a medic.  For example, a patient might
hold up an injury and ask the doctor if it looks infected.

In fact, for health applications, I would make the unusual tradeoff of
sending the full resolution of the camera (640x480) at high quality, even
if this means that we can only achieve 1 or 2 fps.

Re: VideoChat is working now - hooray! - Now how about multi-user audio chat?

2008-10-12 Thread [EMAIL PROTECTED]
There are a number of people that are interested in audio chat.   
Currently there are a group of people that use TeamSpeak on the XO  
but it is closed source and the client has severe stuttering problems  
with 8.2-767. (it is not the firmware because if you boot into  
alternate image 656 it works fine.  There was a trac ticket for audio  
stuttering but can't remember the id).
Now a light weight audio chat activity that could be shared among  
multiple users would be useful.
A few use cases:
A.) school intercom system. ( This how use of TeamSpeak came about in  
the G1G1 sector as an experiment to see if XO could be used as a  
school intercom ).
B.) communication for the blind
C.) inexpensive conference call system
Could this be a lighter weight subset of the Video chat system  
developed as audio chat?

my 2 cents worth,

You can transfers files between systems,  (in the absence of an XS

To install boa on the XO:
su -
yum install boa

If you want more details on how to configure boa let me know and I

 I use boa to pull log files off my XO.

Similarly you get get files off a MS Windows system using IIS.

largest city and the capital etc. as explained). In the future, if

2) I understand that sugar might not have been intended to work

But I also think, since this is a significant investment for many

 My $0.02 (aka. wild guess) is that the following three use cases  
 cover
 90+% of all of them:

 1. files to and from a FAT-formatted USB stick
 2. files to and from a wifi SMB share
 3. email attachments in and out

Another use case I have seen is:
4. files to and from a host system using a ssh connection and  scp.  
(could this be put in an activity wrapper?)
Also some G1G1 users, use scripts to extract data from the data store.

Do you know if trac 8451 is going to be fixed for the G1G1V2  image  
being delivered to quanta?
I think it is a bad idea delivering a self test that is broken. Could  
have bad PR implications.

Just my 2 cents and 20 odd years of SQA experience on a diverse range  
of products.

 That would be a function of the EC code.  Richard, any thoughts?

 q2e19 is a quick-turn release (half-day turnaround from head's up to

 keyboard controller.  It has new and barely-tested EC code plus a
 barely-tested change to the keyboard driver.  It might not

 that happen before.  It doesn't happen all the time; a lot of the

Re: OFW trackpad test woes

2008-10-05 Thread [EMAIL PROTECTED]
Mitch,

Just been testing q2e19a and the self test mode is still buggy. I am  
testing with a G1G1 laptop with Alps trackpad.
Seen several different things happen.

I ran the complete self test a couple of times by cold booting with  
the left rocker  held down.
1.) One time when it went into the mouse test phase as soon as I  
touched the right hand section of the touchpad it left the mouse test  
and went to the next test.

2.) When I ran test mouse from the ofw prompt the screen was left  
black until I hit enter a few times.

3.) Another problem is when you  run 'test mouse' from the ofw prompt  
the screen the following may occur:
Pressure:10
Touchpad protocol botched

mouse selftest failed.  Return code = -1
ok

Touchpad test. Both buttons clears screen.  Type a key to exit.

I can repeat number 3 just by running finger around trackpad while  
varying pressure.

 That could be explained by a queued-up keyboard character causing  
 the test to exit early - like if you typed more than one character  
 when trying to exit the display test early.  I guess I should flush  
 the input queue when starting the mouse test.


 2.) When I ran test mouse from the ofw prompt the screen was left

 That's sort of intentional, so you can see the last state of the  
 screen.  That has some diagnostic value, but maybe not enough to  
 justify the potential confusion.


 3.) Another problem is when you  run 'test mouse' from the ofw

 This one I haven't seen.  I tried to reproduce it on three  
 different machines to no avail.  The dual-mode touchpad protocol is  
 somewhat twitchy, especially as regards switching back and forth  
 between resistive and capacitive mode.  The Linux driver has gone  
 through any number of revisions in hopes of stabilizing the  
 behavior, with only partial success.

 In light of the fact that we're about to switch to new touchpads,  
 I'm inclined to let this one slide.  I'm not sure it's the best use  
 of my time to try and beat this particular dead horse.

I suggest that item 3. be release noted then.

By the way if an Alps trackpad goes bad will it be possible to swap  
in a Synaptics track pad or is that physically impossible

 My hunch is that somehow the EC and the kernel psmouse code get out

candidate-765, Activities directory deleted while running Software Update

2008-09-28 Thread [EMAIL PROTECTED]
While running software update  for candidate-765 the Activities  
directory was deleted.
This was not during the initial run of Software Update after booting  
on completion of
olpc-update but when called from the control panel
Note I had added http://wiki.laptop.org/go/Activities/Joyride to the  
Upgrade Groups.
While software update was running a warning dialog came up stating  
the journal was full.
This seemed to happen while WikiBrowse_English was downloading.
Then when I checked how much free space I had I saw I had  
approximately 200 MB free.

I then went to check the contents of the /home/olpc/Activities  
directory in the virtual terminal but the Activities directory was  
missing
Running Software Update after this happened failed to download any  
activities.  Also it failed to create a new Activities directory.

This problem occurred with a system that had 656 upgraded to  
candidate-765 using olpc-update.

 I've had the same problem when I accidentally double-clicked on the

 Me too. I assumed there were synchronicity issues with activity
 starting/closing/resuming. For example, it has happened to me that
 when I close an activity and immediately resume it, the activity
 cannot create a dbus service. I assumed this was because the previous
 service was not yet completely done yet. But in the light of this new
 discussion it may well have been that I accidentally clicked twice for
 resuming, and since you cannot create the same dbus service twice it
 explains the error.

 The symptom is that there are two colored activity icons in the frame
 plus a gray circle. The splash screen is displayed and does not go
 away. I usually press alt-tab then which dismisses the splash screen
 and switches to the actual activity.

I think you can also get this problem to happen if you click the same  
icon before it has finished opening the application.  In other words  
tab back to the home view and click again.  It was actually easier to  
do this in the old layout that the G1G1 came with(e.g. 656).  In fact  
a number of G1G1 users coined the term 'throbber' for this situation  
as the icon for the activity would sit there throbbing.

 You can't name a paint session in Paint (6220, I added this to release
 notes).

 I can copy Paint's marquee selection and it appears in the frame, but
 the selection seems inactive -- it's gray, has no hover menu, I can't
 drag it.

 I couldn't get paste of a selection to work.

 The Paint fill is so slow that I assumed the app had died.

 The Tools menu looks like a tools palette but you it doesn't show the
 selected tool.  Actually, there is one item that looks like a selected
 tool, but it's the rounded-rect around the current color.

 The color selection swatches would be a lot more obvious if they  
 started
 out as the kid's XO colors instead of black and black.

 Meanwhile the T in the text menu does have a gray background as if  
 it's
 selected, but it isn't until you click it.  And the two effects icons
 have a white background as if they're active.

 If you type a pencil or brush size in their drop-down menus you can't
 dismiss the menu from the keyboard.

 The Pencil size seems unchanged after changing its size.

 Polygon tool cursor doesn't look like the polygon tool icon.

 The Shapes menu doesn't fit the available space, Triangle is in a  
 more
 items drop-down.  I would get rid of the Line shape so the Shapes  
 menu
 can fit on the regular screen.

 The menu is Text, its menu item is Type.  What's the difference?

 The image resize spinboxes are so slow if I paste a previous Paint  
 image
 in, I assumed the app had died.  If I type in the image resize text
 boxes nothing happens but I don't know if it's really slow or they're
 dead to text input.  Ideally they'd immediately show the value you  
 type
 in or spin to but then you'd get a busy cursor.

 I can choose anything from the Journal for Image insert, e.g. a  
 terminal
 session, but nothing happens if it isn't a previous Paint session.  Is
 Paint meant to insert the preview image of non-Paint sessions?

 After unsuccessfully changing the size of an inserted image, the  
 pencil
 tool works but the paint tool gets stuck as a selection marquee tool
 (makes no sense, but it's happened three times to me).

 The two Effects operations are next to each other and have similar  
 icons
 but do completely different things.  It would be better to separate
 them, and change the hover text for the first to Make picture gray


 I know, I know, File bugs.  What do kids make of Paint?

mode including Browse/Firefox.

 Did anyone file a bug?  The Help and Browse activities also suffer  
 from
 this.

 * Out of curiosity I tried running chatzilla (a simple Powered by
 mozilla application) using the system xulrunner.
  (download http://chatzilla.rdmsoft.com/xulrunner/
  unzip
  cd /usr/lib/xulrunner-1.9
  xulrunner -app path/to/chatzilla/application.ini )
 Good news: despite some errors in the console about timemodule.so, it
 worked.  The benefit is the memory and disk sharing.

 * I assume the Help-6.xo application also shares code, since it's  
 using
 Hulahop that Browse uses.  But top shows
VIRT   RES   SHR
132m   37m   11m  Browse
121m   36m   11m  xulrunner (i.e. chatzilla)
130m   30m  7096  Help
 Should Help be sharing more memory, or am I just clueless on top[*] ?

 made these up, but feel free to make your own. The weights (column C)
 essentially defines the importance of each factor as a percentage of a

Sameer thanks for making the spreadsheet world  editable
By the way how are you defining the following terms:-

Stability
Performance
Child Utility
Technical Utility
Grown-up utility
Lines of code

Good definitions of these terms noted in the spreadsheet will reduce  
ambiguity.

Nothing like ambiguity to cause misunderstanding.

Colors!  is far superior to Paint.  Colors! is a wonderful activity.   
A lot of fun  and can be used for learning how to paint.
The replay mechanism is a great learning tool. Using Colors!  in

aiding creativity.

 Hi All,

 Thanks a lot for the input on which activities to ship!

 Here is the list of activities I will to management as my  
 suggestion on
 what we ship.

 Please help test these! See the end of the e-mail for instructions.

 The list I recommend is essentially the G1G1 activities (kudos to the
 team who chose the first set!). In addition to those I list a few  
 which
 got repeated votes (except Chess and Sudoku which are a concession  
 to SJ ;-)

 Original G1G1 activities:
 Browse
 Read
 Write
 Paint
 Record
 TamTam Jam, Mini, on fence: Synthlab,  Edit,
 Chat
 Pippy
 Etoys
 Turtle Art
 Calculate
 Measure
 Distance
 Memorize
 Terminal
 Log
 Analyze

 New ones:
 Help
 Implode
 Speak
 Maze
 SimCity
 Scratch
 Xaos
 StarChart
 Moon
 GCompris Chess
 GCompris Sudoku

 The only significant change from the original G1G1 set is the  
 TamTam. I
 think we should include 2 not 4 so as not to over weight them against
 other activities.

 Let me know if anyone has comments on that (Jean can you live with  
 that?).

 Not all of these are sure to make it. On the other hand it's very
 unlikely that anything else will make it. So if you have an urgent
 request or a specific concern please speak up now.

 Of course, anyone can download additional activities so even if an
 activity is not on this list, it still attracts a lot of users.

 We need help testing these with the latest 8.2 image. We plan to  
 make a
 release candidate today and if it passes smoke test we will add the
 activities and content to create a signed release candidate on Monday!

 Developers,

 Please reply with the final version and URL of each activity which we
 should include in the image. Each one must pass final test and have an
 active and reachable developer to make the final list.

 Morgan,

 can you make sure we have a contact e-mail and name on each of these?
 Also, let me know if you any of them are orphaned or not well  
 maintained.

 All,

 Please test them all one more time let us know how it goes.

 I want to know if each of these passes the tests described here:
 http://wiki.laptop.org/go/Test_cases_8.2.0#Activities

 Please create a new test case for any activity that needs one.

 To do that, go to this page: http://wiki.laptop.org/go/Form:Test_case
 and entering Tests/Activities/nameofactivity to create a new test  
 case.
 Then choose activity from the drop down and you can just paste in the
 steps test from above for a start.

 Then you can add a test result by clicking on the + sign next to the
 test case (it takes a little while for them to show up after  
 creation).

 You can also e-mail comments or test results back to this list.

 Thanks a lot for your help.

 Thanks,

 Greg S

Re: Expected date for 8.2.0

2008-09-10 Thread [EMAIL PROTECTED]
Regarding WPA support remember you have existing G1G1 users out in  
the wild using WPA plus a new G1G1 is scheduled for November time  
frame. It is also possible that a deployment or two use WPA.

There are suspend related bugs in 8.2-759.
1.) There is a nasty suspend related networking bug that requires a  
hard boot to get working again.
Turn on power management, let the laptop suspend, (screen dims), and  
then close the lid.  Open the lid again and the wireless connectivity  
is dead.  Sometimes you have to repeat the lid closing several times  
to get the network stack dropped.  Seems to happen the quickest if  
you have been using the network for a shared activity such as chat  
for a while. ( Bug does not seem to happen if ohmd is logging).
Once this happens restarting sugar will not revive it.  I have had to  
reboot to get wireless working again.

2.) I noticed in build 757 after opening the lid the system would  
attempt to connect to the last network device it had been connected  
to.  With 759 it looks for a mesh first no matter that you had been  
connected to an AP last.

3.).  If the laptop is in suspend, closing the lid does not turn off  
the backlight.  (I look through the USB port after I close the lid  
and the light is still on.  ).

 Hi Martin,

 Go for 8.2-759 - that's pretty close to being a release candidate,

 activities get a kill -9 without so much as a pardon me.

 I don't think we have anyone working on better WPA support, but I  
 might

Re: recognizing a previous connection

2008-09-10 Thread [EMAIL PROTECTED]
It is my understanding that deployments with larger schools will be  
using WAPs and possibly some active antennas (currently a shortage
  of these).  These large schools are more like the G1G1 situation as  
the pupil moves from one area of the school to another they may  
connect to another AP.
I have informed a person involved with deployment at large schools of  
this thread (and the other thread). I am hoping they will respond  
with information about the wireless topography.

On Sep 10, 2008, at 6:25 AM, Mikus Grinbergs wrote:

 When there has been an unconnected period (e.g., while suspended),
 the question has been discussed as to WHICH connection ought the

 the 'most recent connection' to be tried first, unless the user has
 explicitly indicated some other preference.


 But my chief reason for posting this is to point out the difference
 between an education environment for OLPC users, and a G1G1
 environment for OLPC users.  The whole design of Network Manager
 seems to be aimed at the former -- connect to the *same* school
 server all the time;  if it is out of reach, connect to the *same*
 set of buddies (e.g., via mesh).

 As a G1G1 user, I tend to carry my XO with me.  So at 7am I might
 use it at home;  at 10am at the office during a break;  at noon at a
 lunch spot,  etc., etc.   Meaning that continually this XO needs to
 be connected to a *different* AP.  [And I don't like to just erase
 networks.cfg -- there might be values held there that I might not
 want to re-type manually when I next need to use a particular AP.]

 To me, the G1G1 environment is characterized by NOT using the same
 connection each time.  Please don't make it cumbersome to switch APs

 I notice that the .xo bundle for Colors linked from http://

 stream and noticed it didn't pick-up the new version of Color (or  
 Develop-35 for that matter) as the Control Panel (obviously)  
 doesn't use the Activities/Joyride information.

The Software Update control has a Modify activity groups in the  
lower left. This control is revealed once the Refresh of software  
update completes.  Click on this and the Group URL field is release.   
You can add or subtract groups here by supplying the URL.
I discovered that the Group URLs are stored in the hidden file /home/ 
olpc/Activities/.groups
Next time I perform an update from 656 I will have to remember to  
delete .groups and see what it gets populated with.


 Installed both new versions manually using Browse (note that Colors  
 doesn't respond to the stop icon in its activity tool bar, but you  
 can use the keyboard shortcut alt-esc to get out).
How do we get the component activity-Colors! added to track?

 The architecture of the wiki activity group pages is interesting to

 Yea, I was hoping the whispers of semantic wiki stuff was going to  
 help keep all the various wiki references in sync. Perhaps it's  
 implementation is still incomplete? Any information on what the  
 semantic wiki plan is/was all about? Seems to have been some black

 As 8.2 is stabilising, and we read from Morgan's survey that not all
 activity authors are testing on 8.2, it seemed an interesting track to
 play with as many possible activities as we could on 8.2 .

 So we did :-) Adopt an activity today was the motto.

 Overall 8.2 is looking fairly good. Networking and sharing proved to
 be a challenge - see notes at the end.

 Couple of notes
  - most of these have no 'component' in trac, we filed them as
 other-activity, and added the name of the activity as a keyword
  - very hard to find the email addresses of the authors! how do we
 show love to them? why do we have in the wiki maintainer unknown for
 so many activities where the maintainer is well known?

 Wikipedia / Journal
  - Worked very well and it's fantastic to have the content on the XO.
 But installation of large activities shows UI problems with the
 Journal. The Journal UI locks up while copying and unzipping with no
 user feedback.

 Colors-3
 - Worked well
 -,Very high CPU usage even when we weren't painting, empty canvas.
 - Does not close (#8335) apparently due to a bad interaction withe the
 snapshot that Sugar takes when 'stop' is requested.

 Implode-4
 - works well an 3 XOs tried!
 - The first (easy?) puzzle is not one you can use so it's fairly  
 confusing.
 - Loading a large puzzle is also quite slow. (Is it trying to compute
 whether it's winnable?)

 X2O-5
  - Worked very well
  - A bit slow sometimes

 Doom
  - worked well on 3 separate machines.
  -The key bindings however mask the Sugar keybindings. Bug...?

 Mini vMac
  - Works well, and gives the Mac fans little jumps
  - No sound?
  - No network?
  - Display is very small, could it be done with a 2x zoom?
  - Shutdown process is mildly awkward

 Conozco Uruguay
  - Fails to start #8334

 Frotz
 - works well - had fun playing it!

 PlayGo-3
  - launches and collaborates successfully,
  - the Activities page  in the Wiki only offers PlayGo-1 which doesn't
 work on 8.2! (Andrés has already fixed this, thanks!)

 Speak-7
  - Worked well
  - Can we teach it Spanish?

 Horsegame
  - works well! - you can indeed haz a pony
  - Carrots!
  - Apples!

 Asteroids
  - fails to start
  - No module named ImageLoad (#8333)

 FiftyTwo-2
  - launches and seems to offer collaboration, but this in practice
 does not work. The player always plays against the computer, even if
 the activity has been shared successfully.

 Abalone-080601
  - starts and works well.

 SliderPuzzle-5
  - successful launch
  - crashed on one XO (out of 2 tried) but we did not get a log of that
 (Alastair - do you think you can try to repro it and file a bug)

 JigsawPuzzle-3
  - successful launch and play

 Jump-1
  - successful launch and play

 Mimic-1
  - failed to launch, illegal instruction in mmxCombineAddU (#8336)
  - how to contact the maintainer...?

 Implode
  - successful play on two separate XOs

 Calculator
 - successful play
 - Does not display an error on divide by zero - even though it does
 display error msgs in some other instances
 - If fed a large calculation, it locks up trying to resolve it, UI is
 no longer responsive, does not respond to stop. (Grant, can you file
 a detailed bug on this?)

 Simcity
 - Successful play
 - Tiny fonts

 Maze
 - Successful play

 Sudoku
  - Successful play

 Notes on collaboration and networking

 Collaboration and networking...

  ...Oh so much trouble.

  - Collaboration over simple mesh mostly works.

  - Associating to an AP using WPA is extremely unreliable. Some
 laptops do, some after a few tries, some never. Likely to be the
 timing bug that has been discussed before.

  - Network manager is _not _ happy when an AP goes from WPA encryption
 to no encryption. iwlist can see the AP with no encryption but
 ccording to nm-tool, the AP is still requesting WEP. The fix:

 /etc/init.d/NetworkManager stop
 rm /home/olpc/.sugar/default/nm/networks.cfg
 *cold reboot* (does the Libertas driver preserve any state?)

  - Collaboration over unencrypted AP + Schoolserver running ejabberd
 did *not* work at all. I did not have a chance to debug this
 thoroughly, but odd things happen. olpc-netstatus errors out because
 session.info is missing. The client side never tries to register to
 ejabberd apparently. !?

 Credits... a ton of testing and debugging today, thanks to

  all those activity authors!

 Hi Robert,

 Thanks for the info. We should probably do this on the list so  
 others learn too if you don't mind. If you reply again, just add in  
 devel.

 I edited the Joyride page (http://wiki.laptop.org/go/Activities/ 
 Joyride)
  to point to the new Devel v35

 I just updated the activity bundle value by copying and pasting it  
 from the main activities page: http://wiki.laptop.org/go/Activities

 and I updated the version value to 35.

 Try running the SW updater again and let me know if that fetches  
 the right one. If so, maybe we can close another bug!

 The policy on where the SW updater gets stuff is at:
 http://wiki.laptop.org/go/Software_update

 Can you try to fix Colors too if you know where the right one is  
 and how to edit its wiki page from those instructions?

 Scott,

 This could be an ongoing challenge if we have the SW updater coded  
 to use our wiki. Its a little complicated to figure out what  
 version you are using (e.g. Joyride, shipping, peru etc) then to  
 determine where the SW updater is  pulling from and then update the  
 right page.

 Its solvable but needs a lot of communication and takes some time.  
 I wonder if there is some semantic wiki solution here to change it  
 once and have it update everywhere

 Also, we still need a way to post older versions of activities when  
 they are not backward compatible (e.g. if develop 35 doesn't run on  
 656 or 708, we need to say that on the main page and post the one  
 (e.g. v25) that does run on older releases somewhere).

 If we edit the main activities page, to include some more fields in  
 the table will that be a problem for SW updater?

 Skierpage,

 If we can edit activities page safely do you feel up to making some  
 edits there... Maybe propose something on devel then we can approve  
 and execute. Let me know if what we are looking for there is not  
 clear.

 BTW don't mean to give you all the hard problems, its just that

 is being fetched by software upgrade for joyride activities group.  
 (Also there is a caveat for using it on old builds were a patch  
 has to be applied to the journal).  This is a low hanging bit of  
 fruit that could easily be fixed if I knew the correct process for  
 updating the file that gets fetched by software update.
 I have also noticed this problem with Colors! for the joyride  
 activities group were an old version is being fetched instead of  
 the latest.
 Late for work so will follow up later if you need more information..

 Hi Tomeu et al,

 FYI this is a piece of my weekly report that I write for my manager  
 and
 the engineers working for OLPC (aka techteam). Its sometimes picked up
 by the community news.  It just says what I did last week and  
 what my
 goals are for next week.  I hope to send it to this list too in the
 future.

 Cmap tools (http://cmap.ihmc.us/) is a client server application that
 appears to have pretty good traction in schools, mostly in South
 America. We have a request to make it work on the XO. I exchanged some
 e-mails with Alberto Canas (con enye) who is the main application  
 owner.

 There are three main challenges to making this work on the XO:
 1 - It runs on Java. (I asked about Java on a list for that reason,  
 but
 I asked about Java in the browser. In this case its just Java VM).
 2 - It uses multiple windows.
 3 - Its free but not open source.

 The first point seems solvable if they just install Java afterwards.
 Then we don't need to worry about licenses. Its a big install but
 probably not a deal breaker. The performance may be challenging but
 again I think we can make it fit.

 The second point is a tougher problem. Alberto thinks they could
 re-write the application to work with tiled windows so they all fit on
 the XO. The other idea I have heard is that we could run an activity
 which is X-Windows. Then you could launch this activity within that  
 one.
 That may affect performance and would need testing. For the first idea
 of rebuilding the Cmap tools for sugar, we would need engineers to  
 work
 on that which brings me to the third point.

 I'm not sure what free but not open source means. I think it means  
 that
 we can not take a snapshot of their code and fork it nor can we modify
 it and push it back to them. We need to find a way for Alberto to hire
 more engineers if we want them to improve the implementation for  
 the XO.

 The only good idea so far is the X-windows in Sugar idea.

 I'm open to other suggestions on this. Questions and comments  
 welcome too.

 I know of one opportunity in Latin America which is being held up by
 this. There may be more in the future, we'll see. The pedagogical
 specialists here tell me that concept maps are pretty hot in education
 right now. They also pointed me to a commercial tool which some  
 schools
 use: http://www.inspirationsoftware.com/

 Does anyone know of an open source solution in this area?

 If the customers want cmap tools, my first choice is to make that  
 work.
 That's what I'm focusing on right now albeit lower priority than
 shipping 8.2 :-).

 Thanks,

 Greg S

Security and long life issues (Was Re: XO-2)

2008-05-23 Thread [EMAIL PROTECTED]
Richard et al,
(I am passing this to the education list... because it is a mix of tech 
issues with issues related to the general policy about the XOs / and OLPC).

I agree with the level of security that you are talking about.  And I 
understand what are your concerns (some of them are valid for Peru, some 
of them are valid for big cities, some of them are valid for very small 
cities).  But reading your message something came to my mind...  (oh my 
God.. here we go!)

As far as I understand the XOs will be given to the kids as property (I 
hope so... if not then we are feeding the dominance status quo of the 
government / top social class / bureaucrat power / etc.. ... then that 
kind of happening would be part of the problem and not part of the 
solution).

IF the XO is property of the child, and IF the XO has a security 
protection method (that is related / linked) to a validation on a school 
server (or any other protection method that requires that the kid get 
connected with this or that server)... then ... I ask myself...

a) Are we creating a slavery chain ? The kid (who will become used to 
work with his laptop... example: he will get the cost of the potato in 
the wholesale market in Lima and then he will advise his father at what 
price he needs to sell in this or that time of the year...)... then when 
he gets 16 years old (according to what is normal in the Andes 
mountains) he gets married with young lady of the nearest town... so he 
will start a new family in different location... he will live in other 
town... so... he needs to do what ?

a.1) Travel without his laptop.
a.2) Give the laptop to other small kid.
a.3) Get a bride on his own town!!! (smile) (well... the kid has the 
opportunity to try some brides... it is call servinacuy... if you 
don't like the bride (after living with her some months, you return her 
to her parents and you have other opportunities to test another 
bride... don't ask me how many... I don't know! This custome comes from 
the Inca's time and is used in the remote villages in the Andes, it is 
part of a party... by the way, ladies, don't get upset: the bride can 
refuse the boy after living with him for some months... so the trial 
period is good for both... that is all what I know... I am not an expert 
on the issue (my bad luck!).
a.4) Forget the all powerful door to the universe of knowledge 
(XO+Internet) and start a new life
a.5) Don't get married... bachelor life... (smile)
a.6) Hack the security issues and get and independent XO laptop then he 
can travel all around the Andes and get WiFi connection wherever he is 
located (I hope that other XOServers will recognize it as a brother 
from other town and allow him to access the net... I hope so... is this 
a dream? Sorry if I am putting more tasks on the shoulders of the 
developer teams or if I am saying something that sounds weird...)
a.7) Go to a repair center and get his laptop fixed to get ridd of any 
security issue.
a.8) Return the XO to the school (no, please... don't tell me this is 
the chosen procedure... all your efforts will fail like a... ok... you 
say whatever you want... I will be prepared... God help us on this one, 
please).

What about if the kid comes to a bigger city for getting better 
education? and... if the kid get a way to go to a university? (I would 
bet that is the only laptop that most of the kids will get in the next 
30 years... or maybe in his whole life...)... if the kid's family move 
from one small village city to another one... what will happen with 
his XO and, better question, what will happen with his relationship 
with the XO ? (am I nuts? is possible to get a relationship with a 
machine? I don't know... let's ask... Hal... are you there?)

Ok... I can imagine another possibilities... but you got the idea... 
what is the intended route that the XO will follow in the life of this 
kid? Are we teaching them how to surf and then, in a few years we will 
ask them to surf without a board? ok... if that is the panorama it is 
better to know it now.

Are we creating the new slaves of the XO? or this is a gadget that 
they can forget in some years?

I am sure that many people (inside OLPC) has talk about this before and 
I suspect that the answer is not an easy one.  Letting the decision to 
the governments*  is not a valid answer because, in one way or another 
ALL the governments are part of the domination pyramid that we (we?) are 
trying to subvert with knowledge, wisdom, opportunities and good will.

Best regards,

Javier Rodriguez
Lima, Peru

* I am speaking about the governments as a establishment, a layer, a 
level of public administration... not about the people that works for 
this or that government... many of us can work for a government and 
become part of a structure that is very tight.  Some people can go 
beyond the structure and some not.

Edward Cherlin wrote:

You can't expect every kid to spontaneously
generate the sum of human knowledge by playing with plastic blocks.



You don't have the slightest idea what Constructionism is, as this
demonstrates. 


Edward: as far as I remenber you told the same some time ago: do you 
know what is construccionism?...
well... it seems that I knew it, but I studied (a lot more) some of the 
papers and documents that are around...
from the same Papert, from the very same Alan Kay, and all document that 
I was able to pick up... so
(if my 2 neurons are working) now I am sure that I know what is 
construccionism.  But.. again... as far as I remenber you have
stated (or it was Papert?) that construccionism is not to be explained 
in just a few words.


I hope that this aproach changes because IF we can not explain it in few 
words then I have to wonder
how we can think that the peruvian teachers have caught the 
construccionism idea when they took those
prussian and instruccionist order to study the construccionism 
around year 2000.


I think that construccionism is not working fine in Peru.  Or it was not 
correctly taught, or it is not implemented,
or the whole idea is too big (too much words for something that is 
natural to the human been: adapt to the
circumstances.  Everything (even the most prussian or isntruccionist 
method get assimilited by the human
been by a construccionist process).  Everyone can play if this is 
construccionism or constructivism. 

By the way, all the people that is worried about construccionism, should 
train his dog.  IF you are not able
to train your dog using construccionist methods (constructivist, ok?) is 
lacking a deep understanding of
the principles (learning by doing).  Or... let's be fair... they don't 
like dogs! (but a good reading about
all the dog training methods will bring a big surprise... dogs are 
trained with some constructivist methods

from many years ago... ask the germans BEFORE the 1st world war).

All the people that is worry about IF construccionism works or not... 
they can come to Peru and develop a serious
study about how it is working in Peru.  As far as I have learn there are 
hundreds of schools in all social

levels that are applying this construccionism.

I ask myself somethings related to construccionism:

a) Who decided that our peruvian children needs XOs with construccionism 
inside and not a plain Laptop?
(what studies and previous experience have been around the whole world 
to prove that this works... or is
that the peruvian children have taken as guinea pigs to develop and 
prove some educational theories).
ohh... I remenber who... our Minister of Education knew Mr. Papert some 
time ago... well.. the same:
where is the BASE LINE ?  What are the guaranties that this peruvian 
deployment will not fail as the

previous one that were develop in other countries?

b) Please Edward don't cite some obscure document written about some 
schools or some experiment.  That is not
good enough.  You, as any person that develop science, knows that this 
is a pilot and after your pilot
succeed you need to *_VALIDATE_* the data. And for validation you need 
*_BIG numbers of tests_* and analysis.


Are the peruvian kids the one that are going to validate the 
Construccionism/XO as a tool for the
development and poverty solution?  If that is true then you got by 
blessings.  But, honestly, you,
specially you Edward, you need to lower your tone.  Our kids are doing 
you a favor, we, all peruvians
are doing you a favor.. what if ALL THIS FAILS? Some humility and 
recognition that this whole
things is walking on thin ice should be good for the sake of the children. 

Saying all the time I have the reason and all the other ones are wrong 
put the whole project in a very bad situation.
Why? Becuase some peruvian politics believe in what you are saying. IF 
the project fails I will live
in MY country for the rest of the life with all the damage that can 
happen (in educational and
politic affairs), you, Edward, will come back to your daily life.  Who 
is taken the risk? We, the
peruvians.  So, please, don't present the whole thing as the holly 
grial because you are doing
damage to the future not only of the kids but for the whole peruvian 
population. Let's don't play
with the expectations of humble people.  Let's deliver a computer that 
works, first point.  Then
we can add some fireworks and in a very humble tone we can speak about 
the way that the
peruvian teachers will teach to the peruvian kids.  These, in some 
sense, are more my kids that

your kids, Edward.

b) You don't need to brake a leg to know that it will hurt. This simple 
fact can be seen as an instruccionist
way of learning or a construccionism (deduction) way of learning.  Both 
things are sides of the same
coin.  And both things are natural to the human.  The mother that tells 
his boy don't touch the fire
is pure instruccionist.  If she allows that the child feels the heat of

 The idea appears to be extremely old, though not the norm. Ditching

 From what I can tell, c13m is an awful lot like unschooling.
 Perhaps you can explain the difference.

 FYI, what happens _without the teacher around_ is probably not
 what the adults would like. Kids play games, fight, view porn,
 vandalize things...

 It's been 28 years since the Mindstorms book. If the idea still
 hasn't caught on, there must be a reason. The teachers have decided.
 Normal teachers will thwart any effort to change teaching.
 Tying the success of a laptop program to massive changes in
 teacher behavior is not right.

   
Just to tell you (I did it before... I think so...)... I have talk with 
2 teachers here in Peru (one my sister in law and other one a friend).  
Both inform me that almost all peruvian teachers (from the coast area) 
know about construccionism and use it in everyday classromm and 
lessons.  That is because around year 2000 there was an order that need 
to follow IF they want to keep in the public system: they need to assist 
to a set of training days to learn about the new method that the 
Minister of Education will applies to the whole peruvian education: 
construccionism.  So... if someone needs to do a statistical serious 
study about what has happen after this experience then there are 
hundreds of peruvian teachers and schools that have develop some kind of 
actual experience (firts hand experience) in construccionism applied to 
kids.

My sister in law teachs in one of the most exclusive and expensive 
schools (for kids that belongs to the upper top class and sons/daughters 
of diplomatics, politics, etc.) and the other teacher that I have speak 
teach in a public school.  And they have told me at the same time that 
they use construccionism in every day but in a mix (with instruccionism) 
and adapting it to their own daily needs (very peruvian way to do it, we 
are survivors all the way).  So the impression that I got from the 
meeting with this teachers is that they use it at the same time than 
other methods according to the circumstances and according to the kid or 
the school enviroment.  But... they are just 2 teachers and it was a ver 
long and relaxed conversation, not a statistical study.

By the way, according to what I have been told... they went to get the 
training in construccionism because a written notice were given to them: 
do it or you will be out of the educational system.  A very 
prussian/instruccionist way to teach construccionism!   :-[But that 
is normal... no big deal... just a funny situation... sometimes you need 
to lead, sometimes you need to participate, and sometimes you need to 
obey.  That is life from the very born of the human race.

Nick Negroponte has said :

Open Firmware V2, the free and open source BIOS, is now capable of
running Linux, Microsoft Windows XP and other operating systems, and was
developed by Firmworks with support from OLPC. This will enable dual
boot of OLPC XO laptops with Microsoft Windows XP in addition to the
existing Fedora-based system and will become the standard
BIOS/bootloader for all XO systems when completed. With this free
BIOS, the XO-1 continues to be the most open laptop hardware currently
available.

This is totally different that we have been informed, the V2 version of the
BIOS is able to run a double boot.  Huge difference!!!

Good or bad? Everyone has its own answer.  Now the XOs are a more
general tool, a broader range of happenings we will see.

So... all the new 200,000 XOs that will come to Peru will come with this
new V2 Bios.  and the first 45,000 will be updated?  Or we have to

Re: CIPA done

2008-05-09 Thread [EMAIL PROTECTED]




Martin et al,

Not a lawyer... but I know law and I have studied the issue of law and
filtering of the public information and I gave consulting to many
congressmen that were the ones that establish the peruvian laws about
what children can see and cannot see (I will not get in the debate
about what they can see and what they cannot see... but, for the
record: my first priority is to fight against VIOLENCE in the public
media: all forms of violence, in the sports, in the comic programs, in
the news, in the songs (rap this one!), in the movies. Only adults
should be able to see a violent movie. But this is beyond the point of
"filtering").

Peru has signed and ratified the "Protocolo Opcional a la
Convencin sobre Derechos del Nio, sobre la Venta de Nios,
Prostitucin Infantil y Pornografa Infantil". That was done in years
2000 and 2001 (check data at the bottom of this message).

The specific peruvian laws are the law 28119 (December 2003) and its
modifications issue on law 29139 (December 2007)

Internet is like life: more dangerous if you walk in the wild side. If
you are an adult that is fine. If you are a minor then the
responsability is of your parents, teachers or person in charge.
Furthermore we have many laws about the responsability of the ones that
administer the public media: the TV signals, the radio signals, all the
wireless signals, and the use of public property: air, soil, money and
other resources.

With this in mind, I can inform that in Peru this is the law:
a) If you set up an Internet Cafe, or you are responsible teacher or
director or principal in a school, you must PROVIDE a method for
"protecting" the children from what can be seen as "innapropiate"
information (porno is the most known... but if you apology about
terrorism in front of children, or you speak in favor of racism... then
you are in deep waters). The law applies too for the public
institutions (like schools) that provide access to the Internet
(article 1).

b) The filtering software MUST be installed on each computer (not in a
proxy or any other intermediary device). Article 2 ("El cumplimiento
de esta obligacion se hace efectivo mediante la instalacin, en todas
las computadoras, de programas o software especiales de filtro y
bloqueo...")

b) There are huge penalties for those that don't provide the method
(filtering software). The minimum is about 4 years in jail.

c) All the computers involved in this kind of infraction will be taken
from its owners and send to the judge and he will assign new use for
those equipments even BEFORE he finish the analysis of the whole issue,
develop the trial and give a final decision.

d) All the people (owners, administrators) that is involved on the
issue will get not only jail but economic penalties.

All the neccesary laws can be search in our legal official database,
the daily newspaper that comes with all the peruvian laws issue on the
previous day. www.ElPeruano.com.pe (then click on "search laws" and
you put the name of the law that you are searching, or code, or any
word. The whole site is in spanish so your "101 Foreing language" will
be big help.

At the end of this message, some of the more specific laws and norms
that are in use. They are in spanish too.

in 20 different days and it was the same.  I can roughly calculate that 
more than 70% of the use on this
servers were related to sex (Huge Hefner was the one that start this 
commercialization in the U.S. but in
old Peru we had an anncient civilization, named Mochica, that 
manufacture old ceramics with very explicit
sex ceramics, we have them in all museums.  You can imagine the face of 
the Spaniards conquerors (that
were ruled by their holly inquisition when they realize these old 
Peruvian fellows kept sex related
ceramics in every house)... There are thousands and thousands of sex 
ceramics all gymnastics that you can
imagine or dream!   O:-) The kamasutra is a boring book in comparison 
(these ceramics are 3D!) ... Well... just for been
more specific, my old and dear Mochica civilization develop a huge 
civilization, very developed, but...
they eat the heart of the prisioners too (like the Aztecs in Mexico).  
Tip 1: Times change... but SEX keeps on

the field play in all times.

Tip 2: I was in a small, very small village in the high Andes, around 3 
years ago.  I was in an very isolated
town, around 1,000 families approximately (so there was an Internet 
Cafe).  I was not able to avoid
noticing a group of 7 kids (around 10 to 14 years old).  Big noise, big 
smiles, laughing... then I heard
and realize that they were checking the net for nude women... and I 
got surprised when I open ears
very wide (like the rabbit ears on the XO) and I realize that the search 
was very specific: they were
looking for blonds! only blonds!  Tip 2: It happens in the best families 
and in all environments.


Tip 3: About 4 months ago  I have read a report about what are the most 
searched words by country:
uhmmm... I don't want to offend any nationality... but... in Peru is 
sex (I am innocent!), in U.S. was
girl or chick (you just want to talk...)... in France it was gay 
(they are looking for more fun... I guess!)
... I was surprided to realize that in Chile it was gay too... (my 
Chilean friends... just coming out from
the closet?)... and the list continues... Tip 3: It comes to your door 
in many forms and flavors.


My conclusion, from those experiences, is that deviation from what we 
can see as our intended goal

(education) is very near and knock our door all time.

Re: CIPA done

2008-05-09 Thread [EMAIL PROTECTED]

I don't know why Hal... that was not one of my suggestions to the law.

Been in the law is not a guarantee that is related to justice or related 
to technical stuff.


Be totally sure that the kids will disable the filters by themselves... 
(go kids! :-)  )


but the problem is the same: we need to provide some filtering software 
to be installed on the
XO.  It is the law.  If we don't agree then we need to change the law, 
but if the law stays the

same then we have to follow the law.

This could be a design:

a) The teacher takes a XO, or use the XO of one pupil, and update a 
table of forbidden sites

from the internet database (there are many).
b) The other XOs take the data from the main XO (or from the XServer if 
you want or need).
c) Every XO will have a small take this port - send to other port and 
filter the stuff in the middle.
web protocols are easily available and no hard at all.  There is plenty 
of open sourced servers

(for all the protocols) that can be modified to do this task
d) Every XO will tell to the teacher's XO if it is running the 
filtering software.  If not every
teacher must take appropriate measures (it is on the teacher hands and 
responsibility, it is the law,

we just need to provide the filtering software).

I am sure that there are better designs and proposals from the 
collectivity here.

I would love to hear what are those economic reasons.  I am sure that

don't allow collaboration between schools?  Today economic reasons... 
don't get surprise when you hear new
and different rationalizations.

Collaboration between schools would mean total communication between them.

You need to understand what is an UGEL (UGEL = administrative unit in 
charge of many schools in what you would call a county)
... Every UGEL in Peru feels they are owners of this or that 
territory.  If the schools (teachers and pupils)
join then they are going further than the UGEL borders.  This, in the 
eyes of UGEL authorities, is not seen as a good control policy
(control in all aspects that you can imagine). 

Are the XOs property of the children? Yes? Then I shut my big mouth.
Not? Then we (you, me, all) need to think that this no communication 
between schools is just the tip
of the iceberg.

We need to think in different ways to force (friendly) the 
collaboration and bring down the walls that
every small (or big) educative authority needs to put over what they 
think they control (the XOs, the project, etc.)

Is security activation critical in Peru ?

2008-04-24 Thread [EMAIL PROTECTED]

Dear John and all,

I will share some personal points of view in relationship with the security
issue in Peru.  I have work since 1979 with computers and I have trade and
repair more than 20,000 computers from those early years.  I can say that
I know this field very deep from first hand.

/On the other hand, I was told at lunch today by members of the Peru
deployment that software activation is a critical and necessary feature.
/
is Software activation critical?
If the XOs are deployed in the poorest towns then there is small possibilities
for theft and robberies.   In those small villages (with 100 families 
approximately)
all of them know each other: you can not enter or leave the village without
been noticed (or allowed).  Those towns are from 3,500 to 5,000 meters altitude
and there is around 5,000 in Peru.  No young gangs there.

If the XOs are deployed in bigger cities (that is the case for most of the XOs 
in
Peru from the information that we have got) then there is a theoretical risk.

/In previous deployments of computers, Peru saw a high theft rate in the
delivery process.
/
Previous deployments... do you mean the Huascaran project then we (the
public opinion, the media) doesn't have a clue about this.  That delivery
is an old fact, very hard to track its accuracy (but not impossible).

If you mean XOs previous deployment then is the same: we, the public
opinion and the media, and the Congress... we don't know a bit about
that fact.  In this case there would be high responsibilities for many
people involved in the deployment.  And I am 99.99% that the robbery
has not happen without the participation of at least one person that
knows inner things about the deployment (that is common issue, ask
any police in your country where he would search).

If the robbery has happen as part of a bigger robbery then it was
an accident not related to some bad guys wanting to get some
XOs, it was a general robbery.

/The activation process allows them to tell potential
thieves and potential purchasers of hot systems that the laptops will be
useless bricks.
/
No way.  It is just another wall to climb.  You know Russians? well... 
we have some Peruvian groups that are as skillful as the Russians are.  I don't say

that with proud, I just letting know what happens here.  There are
Colombians experts that come to Peru to clone every bit of any digital
system that you can imagine: credit cards, bank codes, computer security
systems.  It is, as you know, a matter of time, interest and resources.

/Here in the US, the cost of disassembling, switching SPI flash chips,  
and reassembling approaches $60 - $70 dollars (I asked several small job

shops for quotes.)
/
well... some guys here will be more than happy to ask just $10 for doing
the same job (again my words come without any proud on them).

I think that the critical things for Peru are :

a) Guarantee that the XOs will be property of the children.
b) Guarantee that there will be REAL content (not the kind that exist today, 
with just one author (not very known) with more than 30 dark publications).
c) Guarantee that the XOs will be a COMMUNICATION system with the world (not only a 
communication tool between a very poor group of children that will construct 
their solutions based on their limited experiences without taking in account what the 
human race have develop during centuries).

I ask your pardon for these so biased points of view.

With the best regards,

Javier Rodriguez

In my opinion, shared by other engineers at Quanta, the proposed
hardware side of P_THEFT would not have slowed you down much.
Dremel-ing off the epoxy wouldn't take long.   The effect it WOULD have
is to add at least a hour (if not 24) of latency to the manufacturing

have increased the price.   I discussed this with numerous people at

Hello Yama and all,

I am afraid that maybe americans that are in charge of developing were 
the XOs will be located can think that they are installing the XOs in 
andean humble towns.  And according to what I am reading maybe the 
goverments (my goverment!) is giving instructions to install this on 
this town or this in other other town.  But, I am suspecting that these 
are not the humble towns.  They look humble for the american eyes, and 
sure that they are poor for the developed world standards.

Humble tows and villages in Peru: IF there is a youth gang in the town 
then you can be TOTALLY SURE that it is not a small town or a humble 
village or an isolated area.  No way.  I don't know Bolivia very deep 
but in Peru the humble, poor, isolated towns and villages are located 
over the 3,500 meters, they have a total population of around 100 
families,  they have a school with just one teacher (that is not able to 
travel to a big city to get XO training), 50% of the adult women don't 
have national identification document or are included in any registry, 
50% of all born babies will not reach the 12 years old mark, there is no 
electricity and they are 5 hours away (by car) from the nearest 
civilized (occidental?) town (that can have around 1,000 families).  
In Peru there are around 5,000 (five thousand) villages and towns that I 
would call humble, forgotten, isolated.  So, you add another 
parameter to the recognition signs to know were we are: IF there is 
SOME risk of a young gang stealing the XOs then we are not in a humble 
town.  If we add all the previously signaled factors then it doesnt 
matter who tell us what or in wich scenario we are  located: we will be 
able to recognize if we have reach the poorest between the poor.

Other different thing are the forgotten poor areas near the big 
cities: then we find young gangs, no doubt.  Too much.  They use 
swords (sorry... the spanish word is machete... ) and guns.  As any 
young gang in the worst neighboorhood in developed cities.

I hope this helps to all involved people to recognize the real danger 
that we will face in humble towns: not reaching them.

 One advantage of OLPC in humble towns is the real support of the

 been mentioned in another list the real risk of (city) youth gangs 
 taking away XOs just for the fun of it, to simply ruin the day for a 
 kid.  Such a thing would be promptly dealt with effectively, with 
 legacy discipline methods for the youth involved, in any small town I 
 can think of.

 An aside : when I was last in New York (for the story jam a couple 
 weekends
 ago) I saw a UNICEF poster display of a disaster-area school in a 
 box --
 two suitcase-sized containers with all of the materials and 
 power-generators
 needed to run a single server creating its own sat or radio internet
 connection, and a few attached terminals.  The design was for regions 
 with
 no infrastructure at all.  A poster mockup listed XOs as ideal 
 terminals...

 One of my crazier scenarios of going to Bolivia is of going by land, 
 with just such a setup, running XOs all along the way.  Might still 
 happen, though I have other fish to fry right now.

one.  Who will

Yes, yes, yes.  It is harder to put the XOs in the WORST scenario. And maybe 
20% of the kids
that are now 6 years old will not reach the 12 years old in those forgotten

There are schools in the surroundings of Lima with no light, no tables, no desks, no chairs.  
Every kid is sit down in a brick.  The teacher

But for sure that they exist, dozens? Yes, no doubt.

Ah... the last earthquake gave us another opportunity: just 3 hours away 
from Lima, in the coast, no mountains,
90% of the schools have been destroyed.  In this Ica region Children 
are studying (if they are studying) in any kind of
temporal school ... in the worst conditions.  There must be more than 
200 schools (all sizes) destroyed there.
Those kids deserve the opportunity to get a XO that can improve their 
educational conditions? Yes. No doubt.

the POOREST children in Peru.

There are four networking scenarios:

Re: A proposal to give some DICTIONARY pre-installed on the XOs that will be delivered to Peruvian Kids

2008-03-11 Thread [EMAIL PROTECTED]

From the threads...

For the XO, it would be great if dictionaries were *not* constant 
databases. Many of the countries where the XO is/will be deployed have 
local languages for which good free electronic dictionaries very much do 
not exist. Moreover, even in places where the local language is 
digital-age, creating a schoolwide jargon file would be a great project 
for involving the kids.


I agree: some dynamic database will be better than a static 
database.  It is not hard to build: just add a form and some 
append/sort routine to the main database.  Easy to say! (smile)... the 
upgrade/add words option can not be done in plain javascript  (it goes 
against the idea that javascript comes from the server and runs on the 
client machine in a typical Internet connection... many security issues 
raise up!).  So... the add/upgrade option or form needs to feed some 
php or java or phyton or... any other language that can be installed 
on the XO (I don't know which ones are installed in this moment... which 
languages come installed with the XO? Phyton and... what else? )


_*Sharing new words*_: how the modifications of one user can be shared 
with the rest of the group or the rest of the neighborhood ?  
Possible answers:
* The school server will collect, organize and share the additional 
words  meanings.
* The MESH will be the one that will share (automatically?) for all 
additional words.  The mesh IS the server.


The problem with my all in memory proposal is that the XO has 256MB of 
memory... how many megabyes are available for user programs (activities) 
after the XO boots and call the Sugar enviroment? How many can be used 
by the all in memory translator without retarding the most common 
tools inside sugar (like a common user that is playing with eToys, 
Firefox browser and Tam-Tam... just for example...).


When we realize how many MB are available we will know IF the dynamic 
database can grow based only over the free memory or it needs to work 
over a bigger medium (like the 1GB falsh memory)  or ... other options? 
uhmm... setting up a ram disk in the flash memory and then the 
dictionary database can be bigger...


_*Size of dictionaries: *_Dictionaries no need to be huge.  These are 
for children and young kids (6 to 12 years old).  Since dictionaries are 
just words (no images) the size of the words database will be small.  
In my database 16,000 english words (many are for adults... for I have 
not clean the database)...with their translation, takes around 600 K.  
So a  fully revised children edition would be smaller in size.


Other use of the seach  find routines of these dictionary 
programs:  I am speaking about dictionary... but it is an error from 
my part... what we are developing are translators.  But it is the very 
same routine to develop dictionaries: just replace the 2nd part of the 
equation: the translation will become the meaning.  So we will have 
english word = spanish word or english word = english meaning ... 
and many other combinations: common phrases... localisms... concepts... etc.

I had earlier given a free licence to use, and submitted my Indian 
Lexicon (for 25 languages) for inclusion in OLPC.


When you say Indian lexicon... it means a 25 international languages 
lexicon build in India or 25 Indian languages ??? (In Peru we have 
Quechua (around 4 to 6 varieties), Aymara (I don't know if it is a 
unique version, and the Instituto de Verano (NGO) described more than 
40 other languages in the peruvian jungle).


A general consensus may have to be arrived at on the availability of 
basic lexical/language resources at various levels, from primary to 
secondary school levels.


Our goverment (peruvian goverment) says that this project is for primary 
schools (6 to 12 years old aproximately).   I don't think that we must 
ask the children to return his/her dear XO once he get 12 years old... 
we, old grown adults, use many kinds of devices that are small: 
cellullars  palmtops are very common and we check mail, and send short 
messages... if we open the window... why we need to close it when the 
kid reachs 12 years old? (that window reference is without any 2nd 
implication! (smile) ).


Every prospective OLPC user is a child and will not be restricted to 
children alone, particularly in, for example, the rural areas of India 
with one billion population with a large percentage of illiteracy.


uhmmm... that was I thought when I realize there will be 250,000 XOs in 
Peru in the next year (40,000 are here in this moment).  All of these 
machines can CHANGE the whole world because they are the TOOLS to 
communicate with the world.  One of the big problems that will arise in 
2 or 3 years is when these machines will be used to develop VOIP (very 
low bandwith needed).  Communication tools they are! then they will be 
used as COMMUNICATION tools without any restriction. 

Learning tool: in some areas of Peru more than 70% of the women are not 
able to read, that's what official statistics show.  From my personal 
experience I can say that it is not rare in the isolated towns and 
villages that the women are not able to speak spanish (only the men), 
and they have not personal identification document (no I.D they 
don't exist for the occidental society.. but they pay taxes: every soft 
drink, every beer (thats the kind of occidental culture that we carry to 
those towns) has its government tax included (VAT)).


My conclusion: XOs are not for children only.  They will be 
revolutionary tool for this generation.  It should be.

  I agree: some dynamic database will be better than a static

 can not be done in plain javascript  (it goes against the idea that
 javascript comes from the server and runs on the client machine

Effectively, just Python.

  Sharing new words: how the modifications of one user can be

 Possible
 answers:
  * The school server will collect, organize and share the

  meanings.

To keep a record of all dictionary changes made by each individual,
you will need to do something on a machine or site with a fair bit of
memory that intends to be up for a long time.

XOs will probably want a way to merge a new dictionary with their
existing one, from the mesh, a server, or another place; it has no
reason to store lots of changes in memory.

 So we will have english word =
 spanish word or english word = english meaning ... and many other
 combinations: common phrases

Raise the level of the Hardware specifications... or let's do some field tests!

2008-03-10 Thread [EMAIL PROTECTED]

Hello,

I am trying to pass this info to some hardware development list... but 
I don't know where it is or if it exists.


Anyway, maybe some person can register this bug (?) to the tracking 
system... if you consider that this is a bug.. or if it is something 
valuable to be taken in account...


--
http://wiki.laptop.org/go/Hardware_specification


 Environmental specifications

Maximum altitude: --15m to 3048m (14.7 to 10.1 PSIA) (operating), --15m 
to 12192m (14.7 to 4.4 PSIA) (non-operating);

--

The Huancavelica city (big city, poor city) is at 12,100 feet (around 
3,688 meters) altitude.  There are tons of computers in that city, they 
work without any modification.  I think that the 3.048 m altitude 
capacity must been raised... maybe it has not been tested accurately.. 
or.. other reasons? The more isolated children are in the 4,500 meters 
(around 15,000 feet)


Cuzco city is at 12,500 feet = 3,810 meters altitude. (so... no XOs for 
Cuzco city.. and that is the capital of the region... there are hundreds 
of smaller villages in higher altitude in the Cuzco surrounding areas).


Table

10,000 feet = 10.11 PSIA
11,000 feet = 9.73 PSIA
12,000 feet = 9.35 PSIA
13,000 feet = 8.96 PSIA
14,000 feet = 8.63 PSIA
15,000 feet = 8.29 PSIA

Andahuaylas city = 13,000 feet

The maximum altitude in hardware specification for all the equipment 
should be raised.  In Peru the towns (villages) that you can find in the 
3,048 meters vecinity are not the poorest or the ones that are more 
isolated.  Our national president (Mr. Alan García) launch a law 
proposal to do all territories over the 3,200 meters altitude a tax 
free territories.  That is because, in the words of the President, and 
according to all our national statiscall records, the deep poverty and 
the isolation starts at 3,000 meters altitude.  Below the 3,000 meters 
altitude... well... there is poverty in whole Peru... but some tests 
should be done to see if the XOs (and the rest of the hardware) can work 
at more than 3,048 meters altitude.  I think they will work because I 
have seen normal standard PCs and all kind of equipment working at 4,500 
meters altitude.  That is the altitude were all the isolated communities 
(the ones that need more our help) are located.  There are around 5,000 
villages and small communities (with 100 families each village, 
averaged) over the 4,000 meters altitude.  Deep poverty in those areas.


Maybe the manufacturer (Quanta?) can put more light over the issue.  My 
guess is that the capacity of the XOs is underestimated by the 
manufacturer...

Javier

A proposal to give some DICTIONARY pre-installed on the XOs that will be delivered to Peruvian Kids

2008-03-10 Thread [EMAIL PROTECTED]

The English Spanish Dictionary

Number of english words: 16,938  Date: March 10. 09:08 p.m. EST.
Published on http://www.olpc-peru.info/dictionary
Download the zipped files here: 
http://www.olpc-peru.info/dictionary/english-spanish.zip  Size 600K 
aprox. http://www.olpc-peru.info/dictionary/english-spanish.zip


An idea is born
I have read that the boys and girls in the pilots develop in the high 
andes of my country (Peru) has been demanding some tool to translate 
some english words that they want to know.  I understand fully their 
curiosity and need.


A proposal to the XO developers and content related groups
The XOs computers can have pre-installed some files so the kids no 
need to be on line (connected) all the time.  For this purpose I have 
taken some previous works (freely available on the Internet) and some 
dictionaries (free on the Internet) and modify to put them in a form 
that can be used in all XOs.


The system is just 2 files: an HTML file (you named index.html or any 
name, copy it to any directory on the XO computer).  The other file is 
the english-spanish database (a javascript file).  Copy to the same 
directory where you install the .html file.  (ahh... there are no 
directories in the XO... ok... you adapt my words to the XO!)


The systems take 600K of the memory of the XO.  Since the XO has 256MB I 
think that there should be room for a 600K file.  I know better 
approaches exists.


How to install in the XO
Now you can create a direct link or a direct access to the XO 
general shell (Sugar) and put it on the Frame (is it possible)?  If this 
is not possible... well... the Firefox browser that comes with the XO 
can have a pre-installed favorite that open the local file 
(installed on the XO) named english-spanish.html.


It is not practical install the html file (and the database) because 
they are around 600 K in total size.  Too big for downloading every time 
from the Internet.  But running the html file from the very same 
computer that the user have in his/her hands is possible.


Any other idea about how to put this in the hands of the kids 
(pre-installed in the XOs) ?


Tests
I have been using this hacked program and it works...  not the most 
elegant solution... but it works!


Other ideas.. other tests... very welcome!

Things to do:
a) Use a non linear search routine in the javascript.
b) Put more languages (yes, I have a quechua-spanish database too... 
so we can develop an english-quechua-spanish trilogy!)

c) Reverse the database: spanish to english! (done!)
d) Add more databases... more words
e) Develop common sentences ... dictionary... abstract.. database!
f) Allow the translation of sentences based not in a word by word (silly 
thing) but in real context and meaningful concepts.
g) Allow that the boys modify the database so they can add more words or 
adapt according to their needs... that couldn't be done in Javascript 
but I can modify the database so it can be modified with a common text 
file reader/modifier.


Ideas, modification and use of this small scripts
Any idea, or modification of this program, can be done without any kind 
of authorization from my part.  But if you share your findings with me 
(and all the communities involved) that would be a nice movement, but 
that is no an obligation.


Have a nice Spanish book reading! (once I publish the reversed database)

What activities are included in the XOs/Sugar that will be delivered in Peru ?

2008-03-07 Thread [EMAIL PROTECTED]
Hello,

Two questions:

a) I was using the LiveCDs (xubuntu LiveCDs) that exist to test the 
Sugar enviroment.  And I find that they not include very popular 
applications (activities) that are the base (or the most famous) of 
the Sugar/XO enviroment: like TamTam, eToys, and other key players in 
the activities band.

How we can get a LiveCD that includes those famous tools?  Or I need 
to install a full Linux/Fedora and install the Sugar Shell there ?

b) What activites are included in the XOs/Sugar that will be delivered 
in Peru ?

I am sending this request to the Developers list and to the Sugar 
list... and to the Peru list (smile)... I will thank the answer because 
tomorrow we will show XOs/Sugars in front of some people in Peru 
(passing the voice about the existence and benefits of the XOs and 
Sugar) and I would like to show those tools working...

Thanks!

Re: uucp for sneakernet (was Re: Emulating the School...]

2008-03-05 Thread [EMAIL PROTECTED]
Fidonet??!!!  You have put tears in my eyes... I was 20 years old, It 
was 20 years ago... there was no internet (or UUCP
nodes) in Peru... we were a bunch (only 20 people, at most) that were 
interested to connect to something that was
outside the country...  so we call (dial up)... international call to 
some phones located in the U.S. to send our request...
ah! those times... great times! (first time we connect we hire a big 
screen and project the connection so all can

see the connection... crazies, we were crazy kids! ... well, its gone!)

Since I am mounting this small lab to replicate a XO network with 
access to School Server then
I will have to add one more computer (a windows ones) to test the 
sneaker-networking (well... we will

walk 3 meters only! but it is the same!)...

If my memory is not wrong (we are old guys, very old!!!) I learn about 
Fidonet and Compuserve and
BBS and similar things reading a gone magazine named Creative 
Computing... I wonder if the
same innovative spirit of that magazine can be translated to the 
children of this generation with

the help of the XOs  OLPC...

I will check and find for all the UUCP versions (software) in the next 
days... and I will put them
in our website for anyone that want to get back some memories... (or 
help with the tests!)


Best regards,

  http://en.wikipedia.org/wiki/UUCP

Yep.  UUCP is great if there's a phone line that can dial overnight
cheaply, but no Internet.  I released the first free implementation of
uucp (gnuucp), which was later succeeded by my friend Ian Taylor's
Taylor uucp, which I believe is still the best free version.  Ian
[EMAIL PROTECTED] may still even maintain it (last release: 1.07 in
2003).  See:

  http://www.airs.com/ian/software.html

There was also an MSDOS implementation of uuslave (the predecessor of
gnuucp), maintained by Tim Pozar [EMAIL PROTECTED], which was widely
used to gateway Fidonet nodes to Usenet/UUCP nodes.  That was the
first project I worked on to bring thousands of 14-year-olds into the
global network.  See:

  http://www.lns.com/papers/ufgate/
  
If a remote school has a dialup phone connection that can run TCP/IP

over a modem, that's probably better than running uucp over it, even
if you can only run it at night due to telco charges.  But uucp has a
lot of scheduling and queueing support that more modern TCP/IP systems
have forgotten about.

Re: [OLPC Networking] Issues with the wireless mesh devices

I comment,

Hi Kim,

I am very intested in the networking issue... because I am mounting a small lab 
to emulate
the enviroment of the XOs  Acces Point  wireless work...

About DDOS:

At the end of this message the definition of a DDOS (distributed Denial of 
Service Attack... for those that need to know)

Comments:

a) DDOS is possibe ONLY if you are connected to the Internet (technically is 
possible in any enviroment, but lets analyze the most possible common source of 
problems).
b) I imagine the next scenary: 
  1) Only the School Server (if exists) will be directly connected to the 
Internet
  2) The XOs will have private address, not public internet address.

So only the School Server is available for a DDOS.  This lead us to 2 other 
possibilities:
  I) The S.Server is directly connected to the Internet by... (wich provider? 
VSAT? wich service?)
  II) The S.Server is getting the Internet from a tunnel that connects the 
S.Server with the OLPC foundation Internet connection.
  III) The S.Server is connected to the Internet by local connections to 
local internet providers, directly.  The S.Server has its own public IP.
  IV) The S.Server use a dial up to connect to the Internet.  Each time it 
dials the S.Server gets a dynamic public IP address (that comes from a pool 
that the Internet service provider will assign).  The S.Server is a server 
for the XOs... not a server for the Internet.  If you want to deploy an 
Internet Server and get rid of the problems with DDOS then you can hire (or 
the OLPC can provide) space in their servers to mount any server service (!) 
that a kid in Peru (bravo!) want to mount and put at the service of the whole 
world (super bravo! here we come, naked internet at the root... are coming back 
to the 80's??? sorry... it is a dream... dangerous dream!)
  IV) The S.Server is connected to the Internet by other methods, like a USB 
mule (since I am in Peru I will call it from this moment a USB llama !!!)

  Each of this scenary can be build with some protection against DDOS (and 
nothing is perfect), and using NATs will put the responsability of working 
against DDOS (a daily task, permanent) in the hands of the people/team/company 
that provide the first internet public ip address in the other side of the 
NAT.  Each of this options (I to V) has its own ways to work against DDOS.

I don't think that the network admins should be too worry about DDOS because 
depending on the networking design this should not be a problem at all.

If someone can tell me what is the official network design in this moment, then 
I can analyze more this DDOS possibility and tell more about measures to avoid.

Best regards,

-
distributed denial-of-service attack

DEFINITION - On the Internet, a distributed denial-of-service (DDoS) attack is 
one in which a multitude of compromised systems attack a single target, thereby 
causing denial of service for users of the targeted system. The flood of 
incoming messages to the target system essentially forces it to shut down, 
thereby denying service to the system to legitimate users.

A hacker (or, if you prefer, cracker) begins a DDoS attack by exploiting a 
vulnerability in one computer system and making it the DDoS master. It is 
from the master system that the intruder identifies and communicates with other 
systems that can be compromised. The intruder loads cracking tools available on 
the Internet on multiple -- sometimes thousands of -- compromised systems. With 
a single command, the intruder instructs the controlled machines to launch one 
of many flood attacks against a specified target. The inundation of packets to 
the target causes a denial of service.

While the press tends to focus on the target of DDoS attacks as the victim, in 
reality there are many victims in a DDoS attack -- the final target and as well 
the systems controlled by the intruder.

Some ideas:

a) Google and other intense information providers have set up their 
servers to refuse too many requests from the same user in a short 
period of time.
b) filtering (nat or caching software) will be a tool to do the same 
not only with http but with all the TCP/IP protocols.
c) If a pair of XOs turn down an AP... it is an internal DOS.  But, in 
my humble opinion, I wont call it a DOS because there is no intentional 
attack to the server.

 Given that a pair of XOs shut down the local access point and the AP on the
 other end of the backbone link connected to the local AP there was more than
 enough justification to do extra digging.

 If some one was malicious enough to find a number of backbone nodes on the WAN
 then you see the problem here.

 Internet connected or not, the DoS problems remain. Your or my definition of
 DDos is not relevant in the big scheme of things, until the problem is better

Emulating the School Server hardware (first things first)

2008-03-02 Thread [EMAIL PROTECTED]
Hello Chris, Hi Daf,

Great news.

I am located in Peru, tomorrow (today!) On Monday, we (a group of 
volunteers in Peru) will
mount a small lab for helping the global OLPC efforts.

I have check the info about the School Server, I understand that the 
info on the wiki can be
a little old or not upgraded... no problem.

We would thank if you update us with the configuration that we must set 
up for the school
servers, because I have found this contradictory info:

a) Networking devices: there is instructions (written) that the school 
server must have 4
network connections (UTP) to avoid the use of external switches.  But 
there is a diagram
(image) that shows an external switch to develop a network.

b) we can use wi.fi access point (linksys) to emulate the OLPC access 
point... but we need
confirmation about what trademark are you using for the access points... 
in this way we
can use the same.

c) Are the School Servers that will be installed in Peru without fans? 
(wich motherboard)
What is the intended energy that the School Server must consume?  This 
includes only the
CPU or includes the switches/monitor/modem and other equipment related 
to the CPU?
What about the access point?

Finally, we have strong interest in connecting this Linux (XOs or 
regular native installions
over x86 machines) to the normal Windows systems.  The most possible 
scenary that
the OLPC project will find here in Peru is that it will be needed to 
send a USB mule
to the nearest point/town with regular internet access (internet cafe or 
cabina).  We
are studying the Wizzy and all the UUCP related issues.  We have 
detected the need
to particularize some aspects due to the nature of Internet in Peru 
(mostly related to
the dominant position of some telecoms here and its reluctant 
participation in something
that will not be under they control... more than 10 years of this 
position will not
change over the night).  If you have solutions studied for this USB 
mule transport
then we will stop our worries and studies and turn to other issues, 
please let us know.

Thanks and we hope to collaborate with our small forces here.

Best regards,

Javier Rodriguez
