from:"Christoph Derndorfer"

James, Gary, Wad,

thanks a lot for all your input and the information.

We now checked all the XOs which showed these camera problems and all the
connections seem to have been fine. So I assume that what we're seeing is
really the cable failure which Wad mentioned. Unfortunately my Internet
connection here at the library is so sporadic right now that I can't
download the PDF attached to #10148 but I'll try it again later today. Not
sure whether I have the time to still add tape to all the camera modules
tomorrow but I'll see what I can do.

Cheers,
Christoph

 Oh, dear.   You might have run into a failure of the camera flat cable.
 We changed the mainframe

 on older machines (adding two pieces of cellulose tape to the right place
 on the motherboard.)
 Details and the fix are at http://dev.laptop.org/ticket/10148

 As someone already pointed out, please try replacing the camera assembly
 --- it is the quick
 way to see if this is the camera or the motherboard.

Re: Solution for Unimplemented package interface procedure error on XO-1.5?

Hi everyone,

apologies about the confusion wrt to my it's easier comment. The main
reason why I said that is because USB flash drives are popular and in short
supply at the library and so I thought just doing a straight-forward
copying on the laptop would be easier for me.

Anyway, since I arrived early enough this morning I did have time to do the
usual USB-based firmware update and then the upgrade to 12.1.0 worked like
a charm.

Thanks again for your support. My progress here would be quite a bit slower
if I didn't have you guys as a remote backup and knowledge base.

Cheers,
Christoph

Re: Cameras not working on XO-1s

Hi again,

this may sound like a stupid question but how would one go about swapping
out the camera modules?

I couldn't find any instructions on the wiki on how to actually remove the
motherboard from the chassis (probably one of the few things I have never
done on an XO so far). That step seems necessary in order to access the
module because from the front the white plastic piece makes it barely
possible to see the cable and push the connector in place with a small
screwdriver.

Cheers,
Christoph

  I couldn't find any instructions on the wiki on how to actually remove
 the motherboard from the chassis (probably one of the few things I have

 Access the motherboard by removing the back (removing the LCD and the
 microphone cable from the
 motherboard in the process of removing the back.)
 Remove the speaker cables, the keyboard cable, and the battery cables.
 Disconnect the antenna cables to the WLAN module.
 XO-1.5 and later: remove the WLAN module
 There are three screws holding the heat spreader down (1.5 and later have
 4 screws).  Remove them.
 You should now be able to lift the motherboard out, starting with the side
 with two USB ports.

 Remove the camera and camera mount as one unit.
 Be careful not to damage the motherboard when removing the camera mount.
 It is adhered to the
 USB connector with double sided tape.Remove the camera and its mount
 first,
 then disconnect the cable.  When mounting, make the electrical connection
 before placing the camera
 and mount into position.

 When reinserting the motherboard, make sure all cables are clear and
 insert the side with the
 audio/power jacks first.


Excellent, thanks a lot for the step-by-step instructions. If I arrive
early enough tomorrow morning I'll give this a shot.

Oh, and I've taken the liberty to copy-paste your instructions to
http://wiki.laptop.org/go/Disassembly_top. While the section doesn't quite
fit the rest of the page due to the missing photos I think that's the best
place to put them so others can find the information in the future.


  That step seems necessary in order to access the module because from the
 front the white plastic piece makes it barely possible to see the cable and
 push the connector in place with a small screwdriver.

 It is impossible to replace the camera without removing the motherboard.
 One of the most annoying
 simple mistakes I make is mounting a motherboard and starting system
 testing before realizing that the MB
 didn't have a camera mounted..


Hehe, just like one of the workshop participants here on Monday who proudly
announced that he had reassembled the whole laptop again - only to realize
that he forgot to include the back-cover and therefore had to take the
whole upper half apart again. ;-)

Cheers,
Christoph

 That trac entry has the details of the fix, which involves changing
 the main frame of the unit, but Christoph needs the preventative
 workaround, which I don't think is described there.

 The workaround is to put 0.5mm cellulose tape to act as spacer so that
 the camera cable does not get folded so harshly. My rule of thumb is
 as follows: when you look at the mainframe on the side where the
 motherboard goes, you see an circular extrusion right on the other
 side of the speaker would go.

 Place the spacer in the middle of that circle. Does not need to be
 large in terms of surface.

 Put the motherboard + camera assy into place -- when you are in that
 process, observe where the camera cable meets the mainframe and check
 visually that the spacer is low enough that it will not pinch the
 cable.

 hth,


Hey Martin,

thanks a lot for these instructions. Based on Plan Ceibal's error
description I had extrapolated a similar approach and so it's good to hear
that I wasn't totally off.

Unfortunately I'm afraid that we simply won't have time to go through the
18 or so XO-1s which currently don't exhibit the problem during tomorrow's
session. I will however pass along your instructions to some of the local
tech-wizards and maybe they can do the workaround at some point in the near
future.

Thanks again,
Christoph

Solution for Unimplemented package interface procedure error on XO-1.5?

2013-01-30 Thread Christoph Derndorfer

Hey everyone,

while updating a bunch of XO-1s and XO-1.5s from the Lubuto Library Project
here in Zambia today we ran into an XO-1.5 which displayed the following
messages upon trying to do a secure reflash 12.1.0:

Filesystem image found - Signature Valid
Unimplemented package interface procedure

A quick search on w.l.o turned up this ticket from 2010 (
https://dev.laptop.org/ticket/10017).

While it does say that the bug was fixed in subsequent versions it doesn't
really provide a solution on what to do when the issue is encountered.

Am I right in assuming that doing a separate upgrade of the firmware and
then running the OS reflash again would address this? Or is there anything
else I need to do?

Thanks,
Christoph

Cameras not working on XO-1s

2013-01-30 Thread Christoph Derndorfer

Hi again,

another issue we encountered during today's workshop session was that on
3~4 XO-1s the camera didn't work (all machines are running 12.1.0 with the
associated firmware).

The effect in Record is always the same: a grey still image. However when
running the hardware self-test 2 of the machines passed the test even
though the camera output on the display was total noise. With the other
machine or two the self-test failed.

Since I've never seen issues with the camera before I was wondering whether
there was anything we could try beyond verifying that the camera connector

 That sounds accurate. If the machine is locked and you want to avoid
 the hassle of getting a dev key, take the file
 /bootpart/boot/bootfw.zip from a XO-1.5 12.1.0 machine and put it in
 the same place on the XO in question, overwriting the previous file.
 Then reboot the system with power attached (normal boot - don't try to
 reflash yet), it should auto-update the firmware.


Hey Daniel,

thanks a lot for the quick reply and clarification.

The way you describe sounds even easier than doing the regular USB firmware
upgrade (
http://wiki.laptop.org/go/Upgrading_firmware#Upgrading_using_a_USB_drive)
which I was going for.

Cheers,
Christoph (still not finished with my studies, just in case you were
wondering;-)

Hey Daniel and all,

I was wondering whether you have an ETA for the final 13.1.0 release?

The reason why I'm asking is that I'm heading to Zambia on Saturday evening
to give a repair and maintenance workshop at the Lubuto Library Project
which Mike has been supporting for a while. Since I'd like to get all their
XOs up to 13.1.0 in preparation of Mike's education workshop later in
February and local Internet connectivity will likely be limited it would be
great if I could bring along the images for XO-1/1.5/1.75 on a USB drive.

Thanks,
Christoph

gerald.ard...@gmail.comwrote:

I wanted to share that we have faced the same criticisms in our school
regarding the XOs. For the last four years, the teachers and students have
complained that the devices do not connect well or reliably to our wireless
network.

Obviously, in our case, we have a wireless network and essentially
continuous access to the internet. But, what I have had to fight against is
that this is the most basic use of any computing device.

The only way I have been able to stem this tide is to come up with
projects and programs that made use of the XOs as standalone or mesh
networked devices. For example, we have done a lot with Memorize and Etoys
and Scratch (and beginning to work with TurtleBlocks). I have found that
once the students and teachers are involved with these activities, the
internet stuff goes away.

But the bigger point that is missed in the story, and the broader
conversation, is that the XOs and Sugar tap into non-traditional methods of
teaching and learning. When this invisible line is crossed, real magic
happens. It is the conversations which illuminate this invisible line that
is tough.

Gerald,

please don't forget that very few of the teachers in Peru have the
affordances available to you when you worked against that tide and helped
your pupils reach that invisible line. You have received countless years of
professional training, have ready access to the world's and the community's
accumulated knowledge about using XOs and Sugar (thanks to the Internet),
deal with student bodies who generally don't go hungry, have a pyhsic and
social infrastructure that's available at very few Peruvian schools, etc.

In short, I believe in the importance of crossing that invisible line and I
have been lucky enough to see some glimpses of that happening in the past
few years. However a significant number of pupils and teachers in Peru are
miles and miles away from that line and will need other ways of support to
even get them close to it.

I also think it's odd to see how the role of the Internet and the
connectivity it enables between people is apparently deemphasized in this
conversation. I remember a time where Connectivity was one of the 5
principles of OLPC, and for good reasons I dare say. Due to the limitations
of the Mesh network (and similarly so the newer ad-hoc networking options)
and the lack of infrastructure components such as access points most pupils
and teachers in Peru barely have access to local connectivity and all the
affordances (incl. Sugar's collaboration features) and value it provides.

Also I believe that people here will simply have to get used to bad news
(whether fully justified or not) coming out of Peru. The project there
still has potential but unless a lot of additional resources and brain
power are invested into its overall value proposition and usefulness will
always remain questionable at best.

Cheers,
Christoph

Just my two cents.
Gerald

  Gerald,
 
  please don't forget that very few of the teachers in Peru have the
  affordances available to you when you worked against that tide and helped
  your pupils reach that invisible line. You have received countless years
 of
  professional training, have ready access to the world's and the
 community's
  accumulated knowledge about using XOs and Sugar (thanks to the Internet),
  deal with student bodies who generally don't go hungry, have a pyhsic and
  social infrastructure that's available at very few Peruvian schools, etc.
 
  In short, I believe in the importance of crossing that invisible line
 and I
  have been lucky enough to see some glimpses of that happening in the past
  few years. However a significant number of pupils and teachers in Peru
 are
  miles and miles away from that line and will need other ways of support
 to
  even get them close to it.
 
  I also think it's odd to see how the role of the Internet and the
  connectivity it enables between people is apparently deemphasized in this
  conversation. I remember a time where Connectivity was one of the 5
  principles of OLPC, and for good reasons I dare say. Due to the
 limitations
  of the Mesh network (and similarly so the newer ad-hoc networking
 options)
  and the lack of infrastructure components such as access points most
 pupils
  and teachers in Peru barely have access to local connectivity and all the
  affordances (incl. Sugar's collaboration features) and value it provides.

 No one is discounting the dire state of connectivity in Peru and as
 CJL pointed out, there are people activitly trying to do something
 about it, not just talk about it.


Point taken.


 
  Also I believe that people here will simply have to get used to bad news
  (whether fully justified or not) coming out of Peru. The project there
 still
  has potential but unless a lot of additional resources and brain power
 are
  invested into its overall value proposition and usefulness will always
  remain questionable at best.

 I think you are projecting your own agenda on this discussion.


And you're not? ;-)


 Again,
 no one is burying their head in the sand re short-comings, but at
 least some of us believe that lack of Internet access does not mean
 lack of opportunity to learn.


I'm not saying that a lack of Internet access equals a lack of learning
opportunities (and I agree with your fundamental criticism of the NPR
article there). At the same time there's no doubt that what is already an
*extremely* challenging thing to do under the best of circumstances
(getting across that line) is made even harder without Internet
connectivity or offline substitutes such as school servers.

Christoph

  The post says as yet unreleased XO 1.75. What's the official status
  on the 1.75? Still as yet unreleased?

 It's been shipping for some time now.
 I don't know where they got that information.

 And the correct name for the new generation will probably be XO-4 and
 XO-4 Touch.


I'm confused:

What's the difference between the XO-4 (without the touch) and the XO-1.75
going to be?

Also, Neonode's press release refers to the touch-enabled device as OLPC
XO Touch 1.75 which fits in much better with the current naming scheme.
Especially since an XO-4 which will pressumably become available before the
XO 3.0 tablet sees the light of day would make the tablet seem outdated
from day one.

 deployment of laptops to kids?  Which deployment is it?


Maybe I'm wrong but given that Evolution in Design's list of clients (
http://www.evolutionindesignz.com/clients.html) includes GogoNews (
http://www.gogonews.com/) which recently announced that they're working on
a custom, Linux-based browser specifically for use on OLPC XO devices to
become part of the collection of default applications on new XO computers
and offline capabilities are also mentioned (
http://www.businesswire.com/news/home/20111214005404/en/GoGoNews-Delivers-Universal-News-Content-Laptop-Child)
it sounds like Anthony is part of that effort.

Where do I collect my prize? ;-)

 If you are just writing a software program, I don't think you should
 modify the base system, because you will break other people's software
 if they use the older version of xulrunner.  It would be better to bundle
 the newer version of xulrunner inside your program, if you need it,
 although that would waste some disk space.

Hi

If we had a volunteer (English Native language) professional technical
writer, what writing would be of most use to OLPC or Sugar that we can
point
her in the direction of? She currently works with developers to write end
user documentation.

Thanks
Tabitha - NZ volunteers

I think the most important thing is to identify and focus on the
target audience - is the documentation meant for technical users, end
users, teachers, children...?

That's indeed the key question which we also spent some time discussing in
San Francisco. The current Help activity + corresponding FlossManuals was
mainly written with Give 1, Get 1 users in mind so there's definitely quite
some rework that needs to be done if we're looking to cater to other
audiences.

We (OLPC Australia) would be happy to suggest ways in which the
documentation can be improved, using our experience from working
directly with teachers and communities. Our online course
(http://laptop.moodle.com.au/ - you can log in as a guest) might
provide some inspiration.

Thanks, I'll take a look:-)

Our Education Manager has some advice, based on her experiences with
reading the publicly-available documentation:

- Make sure the Sugar and XO Floss manuals are up-to-date,
easily readable and have all the necessary information.

- Externally available documentation: It’s imperative that
minimal knowledge is assumed, which I think is the hardest part. Pages
need to have less information rather than more, good user interfaces,
lots of useful images, clear headings and language that is simple and
precise. My concern with a lot of the external documentation is that
it is sometimes overwhelming, difficult to navigate (both between
pages and within them) and written for a technical audience rather
than a basic user. Trying to target both a technical audience and a
basic user in the same documentation means you are more likely to lose
the basic user. Perhaps some of this documentation needs to be
separate out. The main issue I see with the Wiki is that it’s
difficult to navigate and find information from the menus. This isn’t,
per say, the role of a technical writer, but tidying up navigation in
the Wiki would make it more accessible.

- Someone to simply document the activities available
(purpose of the activity, how to use it, any tips that are not easily
discoverable, and what you can DO with it- exemplars of use)

That point is also on our agenda:
http://wiki.laptop.org/go/OLPC_SanFranciscoBayArea/OLPCSF_Community_Summit_2011/Help_Activity_Refresh#Revised_Manual_Contents

- There are lesson ideas and examples of practice all over
the place. It would be amazing to synthesise this as much as possible,
so they are not so difficult and time consuming to find, and to put
them in a uniform format. I’m not sure what the best way to approach
this is, but from an educational perspective, knowing not just HOW to
use the XOs but WHAT to do with them is far more important. Making
these ideas easily accessible, in my mind, is quite important.

Also something that was discussed various times in San Francisco (and
previously Paris). It definitely sounds like at least Australia, the
Philippines, Jamaica, Madagascar - Nosy Komba, and Austria have some common
needs here which I think we should expand on in a seperate thread. :-)

Cheers,
Christoph

 Is the FLOSS - help activity process documented anywhere? I don't think
 we are able to help with improving the i10n process or the activity build

  Agreed on the general goal. My understanding is that the Help activity
  is assembled from content from several manuals about sugar and
  activities, created and edited at FLOSS Manuals.
 
  I suspect that FLOSS Manuals has a means to maintain translated
  versions, not sure how well it works, but several existing manuals
  offer alternative language versions.
 
  Maybe the FLOSS manuals platforms is terminally borked in this regard,
  I honestly hope not. Because Pootle is not suited for this style of
  documentation -- we sure want something wiki-ish that handles
  paragraphs, tables, embedded images...

 (earlier message sent prematurely)

 I need to spend a little bit of time on FLOSSManuals,  I'd heard
 something about hem incorporating booki

  http://www.booki.cc/

 but I have not investigated it extensively since then to see how much
 of an improvement it is with regards to L10n.

 L10n of long-form content is an area where I think there are some
 excellent bits and pieces, but I'm not convinced that there is a
 really nice end-to-end solution yet.  I think very highly of
 FLOSSManuals as a book publishing platform, but was less than
 impressed with it's L10n workflow.  I am happy that several of the
 Sugar OLPC boks have been translated, but these have been time-focused
 efforts requiring a lot of coordination and not amenable to the slower
 accumulation of collaborative work that characterizes Poolte L10n
 work.

 I like also wikislicing as a content collection method and Wikimedia's
 WikiBook effort has some superb features with respect to content
 collection and publishing.  To the extent that orthologous articles
 exist across wikis it can also address L10n, essentially by slicing
 pre-localized content.

 Unfortunately, while the PDF output from WikiBooks is quite
 beautifully formatted, it's size is large and PDFs are not that easy
 to edit after the fact.

 http://wiki.laptop.org/go/File:TamTamSuite_collection.pdf

 The ,odt output option from WikiBooks is easier to edit, but I think
 it has real deficiencies in formatting, and IMHO, is frankly ugly.

 However, both of these formats produce rather large files compared to
 simple HTML and an HTML output option is not currently available.

 My reasoning on requesting availability of a plain text version is
 that facilitates bringing the strings to the localizer, instead of
 forcing you to bring the localizer to the strings (and a new tool).
 Admittedly, this has its; own flaws and requires more substantial
 post-processing to get a nicely formatted product.

 The ideal all-singing, all-dancing long-form L10n tool with content
 management system features and e-publishing features may be out there,
 but I haven't seen it yet.  I do welcome others to join in the
 exploration of the various options and techniques for cobbling
 together a workflow that optimally meets our needs, but most of all, I
 encourage thinking about i18n / L10n in all aspects of our work.


Cjl,

thanks a lot for reminding us about the importance of localization:-)

Samy from France was kind enough to collect some links and information for
translation tools in another thread (Open translation tools) and I hope to
have some time to look at them in some detail before I head to San
Francisco.

Maybe what we should try to do is try to compile some sort of good practice
guide for translation of documentation (as opposed to software itself) for
these types of events...

Christoph

 Instead of offering a mechanical keyboard in blue units, which
 entailed some manufacturing complications, we'll have it as an
 optional on the usual green/white.

 It's different enough that it's a separate model altogether (CL2 for
 membrane, CL2A for mechanical kb) -- meaning it's different enough
 that it requires separate certifications (yup, double up the cert
 costs). This makes sense if you consider that CL2 can be certified as
 achildren's product thanks to the safer design of the kb.

 We are doing some background work to improve the membrane kb --
 mechanical engineering is hard and can't be rushed (not with good
 results anyway). So it's hard to know whether it'll make the cut. Keep
 your eyes open for C1 stage units -- :-)


Thanks a lot for the explanation, I always find these tiny production,
engineering, and certification details quite fascinating! :-)

 code that makes words appear on the screen.  It may alos be that it is
 available via Pippy for modification.


Hehe, that was also my first thought but it doesn't seem to be the case.

And if it's intended as a traditional first example for children then it
would be good to add some explanatory comments to the source-code because at
the moment it seems to be overwhelming as an first-encounter experience.

Okay, I just confirmed that this is indeed caused by drag'n' drop.

While playing around with os22 with the language set to Spanish Uruguay I
also noticed issues with missing Spanish translations in two activities:

* Record v91: The labels Timer and Duration and the corresponding
dropdown menus in the toolbar are in English.

 You can check on Pootle and you can check in git.  Git is typically
 more impotant to seeing it in the builds.

 Pootle Record (lang-es)
 http://translate.sugarlabs.org/es/honey/record.po?view_mode=translate

 Git Record (lang-es)
 http://git.sugarlabs.org/record/mainline/blobs/master/po/es.po

 These two strings are complete in both.  If they are done in Poolte,
 but not git, then the lang-admin needs to commit.

 This one is a little more complex.  The git POT has the strings, but
 the strings don't have proper location codes (a template issue), so
 they may not be showing.

 Git Paint (lang-es)

 Thanks for the testing feedback so far. This release fixes a couple of
 major issues.

 Notable changes:
  - Fixed bug where olpc-update was not working and could even break
 your system on next boot. Sorry about that. Users of build 20 and
 build 21 will have to reflash this image directly, rather than using
 olpc-update.
  - Fixed a bug introduced in build 21 where XO-1.5 wireless hardware
 was being reset on every resume

 Tickets closed:
 #10942  /versions/running symlink not created correctly
 #10944  rfkill driver stopping/starting mmc host unnecessarily


Using os22 on an XO-1.5HS I keep running into an odd issue whereby at some
point almost all of the function keys (views, Journal, frame, volume, NOT
brightness) stop working after the machine comes out of suspend. This has
happened three times over the course of the day.

I've now spent the past hour trying to reproduce this behaviour with a
combination of automatic suspends and manual suspends but no luck.

Has anyone else seen this before? If not I'll play around it some more and

 Yes, I've seen that, but haven't been able to isolate it further.  I
 suspect it is SD card access delay, where slow writes are queued before
 the reads that are needed to respond to the keys.  The requested
 function is eventually done within a minute.

 You might force it to occur by doing a lot of web browsing then allowing
 the system to suspend.  Therefore on resume it is less likely that the
 relevant code is in memory.


James,

thanks, I'll try this Web browsing + susped approach tomorrow and then
report back here.

Thoughts on Windows 8 UI / touchscreen UIs which could also apply to Sugar on tablets

2011-06-03 Thread Christoph Derndorfer

Hi all,

I stumbled across this article called Why Windows 8 Is Fundamentally Flawed
as a Response to the iPad (
http://daringfireball.net/2011/06/windows_8_fundamentally_flawed). I think
some of the things that are being said there could also apply to Sugar
running on tablets and actually ties in very well with some of the related
discussions I had with C. Scott and Bert in Uruguay.

To me the key phrase in the article can be found in the last paragraph where
it says:

Apple’s radical notion is that touchscreen personal computers should make
severely different tradeoffs than traditional computers — and that you can’t
design one system that does it all.

Definitely some good food for thought in my opinion...

Cheers,
Christoph

 From the PoV of the user, yes, it looks like a mountpoint.
 Technically, you can mount it at the linux kernel level, at the gnome
 IO libraries level, or from Sugar, with a pure python implmentation.

  What would be the best way to get this working on Sugar?

 You don't have a lot of time it seems. I'd implement it on top of
 gnome VFS of in pure Python. In both cases, I'd make it look like
 another disk from the Journal (as an initial implementation at least).

 I'd say talk with Martin Abente, he's looking into this problem space.


Could we maybe split this thread and keep technical discussions focused on
XS-devel and Sugar-devel lists? I think this could also also help in getting
some non-technical and/or end-user feedback and suggestion from people on
IAEP who aren't into all the technical details (something which I think tch
was also interested in).

 Sugar doesn't seem to place any limits, so conceivably there could be
 100 kids trying to access the same instance. I tried a game of
 Memorise on XOs in a class last week, and I saw errors such as
 children being able to connect to the session but not actually
 participate (which basically halted the game when it came to that
 child's turn).

 This can be frustrating for the children and the teacher. If we could
 manage their expectations, they would be much more receptive.

 Games in other media (board games, console games, etc.) cite a hard
 limit on the number of players (e.g. 2-4 players). Might it be
 useful for us to do that in Sugar? This could be implemented as a mere
 recommendation or a hard restriction in the code.


Hi Sridhar,

I seem to remember some discussions about an activity or its metadata
specifying for how many users its made for (e.g. two users for certain
activities and games). Additional users would then be able to observe the
collaborative mode in some sort of view only mode. Unfortunately I now
can't seem to find the appropriate e-mail threads on the lists...

 Perhaps you recall this meme:

 class MyActivity(Activity):
def __init__(self, handle):
Activity.__init__(self, handle)
self.max_participants = 1

 However, I cannot see any code in sugar-toolkit that uses the
 max_participants property for anything other than deciding whether to
 show the share-with widget.

Hi James,

yes, thanks, that field and the lack of code actually doing much with  
it was definitely a part of those discussions I'm thinking about.

Any restrictions or recommendations regarding SD cards?

Hi all,

the folks from the Austrian pilot project want to equip the XO-1s there with
SD cards. Are there any restrictions wrt size, speed, etc. that they should
be aware of when purchasing the SD cards? I'm particularly asking after
reading James' mention of seeing more issues with newer cards and the XO-1
power off bug.

Or asked the other way 'round: Are there any particular cards or
manufacturers which people can recommend?

 Have a look at my list at
 https://wiki.linaro.org/WorkingGroups/KernelConsolidation/Projects/FlashCardSurvey

 Stay away from brands that typically have only one writable allocation
 unit, these will be slow and wear out very quickly when formatted with ext3
 or other Linux file systems. Higher is better here, and it's something that
 is usually not reflected in the speed class rating. Also avoid those that
 only
 support linear I/O.

 Sandisk cards tend to be ok (especially the Ultra and Extreme versions),
 Kingston tends to be really bad, most others have somewhat mixed results
 though sometimes the cheapest ones can be really good.

 Class 10 cards are not required to support efficient random I/O, so they
 are
 sometimes slower than Class 6 cards from the same manufacturer.

 If you buy a sample, I'll gladly help you figure out if it's any good
 before
 you buy a lot of them, in return for more data for my survey page ;-).

 there. Bert might have other examples...


(Thanks a lot for the heads-up Simon:-)

Yes, I'd also love to see German included again.

Due to a variety of issues we won't be able to do a whole lot at the
Austrian pilot project this year but the 2011-2012 school year (when the
project class is going to be in 4th grade, the last one of primary school) I
definitely want to make a strong push again. And being able to use the
latest Sugar version in German would definitely help here:-)

USB charging while XOs are switched off

2010-09-13 Thread Christoph Derndorfer

Hi all,

going through some of my notes from South America I stumbled across a
question from a Peruvian teacher who had asked me whether future XOs would
allow her to charger her mobile phone while the XO is turned off. Not sure
where she had seen that but I think it combination with more and more mobile
phones going to towards USB chargers this is actually quite an interesting
idea.

Is this a feature that has been considered for the XO-1.75?

Christoph

 if by off you really mean off, then i doubt the USB ports will
 have power when the laptop is off.  if by off you mean in suspend,
 then i'm sure we'll be considering it.


Mmm, if I remember correctly my flatmate's Lenovo T400s has a powered USB
port which works both when the laptop is suspended as well as when it's
turned off...


 we were hoping to have USB
 powered during suspend on 1.5, but were foiled by poor documentation
 of the gpio pins in question.


Okay, too bad to hear that.

Will you make another attempt for the XO-1.75?

Enhancing Sugar to support multiple users

2010-09-05 Thread Christoph Derndorfer

Hi,

I just created a new ticket (http://bugs.sugarlabs.org/ticket/2292) to get
some discussions started on what changes need to be made to Sugar to work
well in an environment where multiple users will work on the same machine
(which is how Peru's next 300,000 XOs will be used:
http://www.olpcnews.com/countries/peru/peru_between_one_laptop_per_child_and_seven_children_per_laptop.html
).

Obviously this touches upon a lot of areas from simple naming of the
machine, over the Journal, backups and probably a whole host of other issues
that I haven't though of yet.

(Additionally it also ties in to the ongoing reorganise home menu
discussion: http://bugs.sugarlabs.org/ticket/1206;-)

 It's because being forced to manage your ongoing work via the Journal

 the rest of the world uses.


For what it's worth: The latest software versions coming out of Paraguay
(based on Sugar 0.88) now support easy backup of the Journal to a USB

Moving this to the devel lists. I think there's still work to be done
on Help. A sprint for that might only take a few hours, perhaps in
combination with one for 0.88? SJ

Yeah, I think we could achieve a lot in a single day since we can build on
existing text and screenshots from the respective release notes and an
article about new Sugar features that I'm currently working on.

This is also something we could maybe work on while I'm in Boston in the
first week of September.

Making OLPC / Sugar Labs more approachable (was: Re: OLPC 10.1.2 Release Candidate 1)

2010-08-08 Thread Christoph Derndorfer

On Sun, Aug 8, 2010 at 3:56 PM, Ed McNierney e...@laptop.org wrote:

 Instructions:

 1. Report bugs at http://dev.laptop.org/newticket - if necessary, register
 first at http://dev.laptop.org/register (as mavrothal kindly points out)
 2. If you have interesting experiences or user information to contribute,
 please do so at http://wiki.laptop.org
 3. If you're unwilling to perform steps 1 and/or 2 as appropriate, please
 don't expect the bug to be fixed, or for anyone else to even know about it.


I know I'm repeating myself here but I find the attitude expressed in these
instructions and particularly point 3 troublesome and a continued source of
frustration for me as well as other people I've talked to. Even more so I
think it's a very clear symptom of the much-discussed disconnect between
developers and end-users in the OLPC and Sugar Labs context.

The core here is that software developers seem very reluctant to step out of
their own comfort zone when it comes to processes and tools (a.k.a. point 3
a.k.a. my way or the highway) yet consistently expect teachers and other
XO and Sugar users to do exactly that.

This leads to the current situation in which crucial information and
feedback from these users does not make it back to developers and the
broader community. Therefore rather than working on things that users need
or need to work reliably (e.g. the Journal) resources are spent elsewhere.

But that's all just basically a recap of the IRC discussion on #sugar
earlier in the week and many hours of discussions with Bernie and others in
Paraguay over the past 2 weeks.

Now at this point I'd normally stop but seeing that I've been increasingly
frustrated about this and have subsequently complained a lot about it I'll
get off my ass and try something to improve the situation a bit.

Over the next 6 weeks (can't make promises beyond that since university and
my job will then start again) I plan to:

(a) Contact people at deployments asking for their input as to whether they
see a need for a closer feedback-loop between deployments and development
(because maybe I'm seeing issues when in fact there are none). For this I'll
rely on the people I know plus the contacts listed at
http://wiki.sugarlabs.org/go/Deployment_Team/Places for starters but please
send along any suggestions on who else to get in touch with.
(b) If it turns out to be a need then ask for input as to how these needs
could be best communicated so we can figure out an appropriate process.
(c) Try to schedule some sort of meeting with several deployments, possibly
as a continuation of the Sugar Labs deployment meetings on IRC or via a
Skype call or something. In my mind the focus here should be input into what
deployments would like to see development focus (more) on.
(d) Compile all the resulting input into a readable format and distribute it
where seen appropriate.

Things I most likely won't do as part of these efforts include (but aren't
necessarily limited to) setting up new mailman-lists, creating a new
category on w.l.o or w.s.o and following wiki talk-pages, asking for a trac
instance, learning to use git send-email, switching to Mutt, booting into
Ubuntu instead of Windows 7, etc. ;-)

As always, let me know what you think.

Cheers,
Christoph

Am 08.07.2010 um 00:01 schrieb Chris Ball c...@laptop.org:

 Hi,

 Now that the 10.1.1 release for XO-1.5 is out, it's a good time to
 talk about OLPC's software strategy for the future.  We've got a few
 announcements to make:

 XO-1:
 =

 OLPC wasn't planning to make a Fedora 11 release of the XO-1 OS, but
 a group of volunteers including Steven Parrish, Bernie Innocenti,
 Paraguay Educa and Daniel Drake stepped up and produced Fedora 11 XO-1
 builds that follow the OLPC 10.1.1 work.  I'm happy to announce that
 we're planning on releasing an OLPC-signed version of that work, and
 that this release will happen alongside the next XO-1.5 point release
 in the coming weeks.  So, OLPC release 10.1.2 will be available for
 both XO-1 and XO-1.5 at the same time, and will contain Sugar 0.84,
 GNOME 2.26 and Fedora 11.  We think that offering this fully
 interoperable software stack between XO-1 and XO-1.5 laptops will
 greatly aid deployments, and we're very thankful to everyone who has
 enabled us to be able to turn this XO-1 work into a supported release!

 To prepare for this XO-1 release, we've started working on fixing
 some of the remaining bugs in the community F11/XO-1 builds.  Paul Fox
 recently solved a problem with suspend/resume and wifi in the F11/XO-1
 kernel, which was the largest blocker for a supported release.  We'll
 continue to work on the remaining bugs, particularly the ones that
 OLPC is uniquely positioned to help with.

 The first development builds for this release will be published later
 this week.

 XO-1.5:
 ===

 We'll be continuing to work on XO-1.5 improvements, incorporating
 fixes to the Known Problems section of the 10.1.1 release notes¹
 into the 10.1.2 release.

 XO-1.75 and beyond:
 ===

 XO-1.75 software development is underway.  Today we're announcing
 that we're planning on using Fedora as the base distribution for the
 XO-1.75.  This wasn't an obvious decision -- ARM is not a release
 architecture in Fedora, and so we're committing to help out with that
 port.  Our reasons for choosing Fedora even though ARM work is needed
 were that we don't want to force our deployments to learn a new
 distribution and re-write any customizations they've written, we want
 to reuse the packaging work that's already been done in Fedora for
 OLPC and Sugar packages, and we want to continue our collaboration
 with the Fedora community who we're getting to know and work with
 well.

 We've started to help with Fedora ARM by adding five new build
 machines (lent to OLPC by Marvell; thanks!) to the Fedora ARM koji
 build farm, and we have Fedora 12 and Sugar 0.86 running on early 1.75
 development boards.  We'd prefer to use Fedora 13 for the XO-1.75, but
 it hasn't been built for ARM yet -- if anyone's interested in helping
 out with this or other Fedora ARM work, please check out the Fedora
 ARM page on the Fedora Wiki².  We're also interested in hiring ARM a 
 nd
 Fedora developers to help with this; if you're interested in learning
 more, please send an e-mail to jobs-engineer...@laptop.org.

 We'll also be continuing to use Open Firmware on the XO-1.75, and
 Mitch Bradley has an ARM port of OFW running on our development boards
 already.

 EC-1.75 open source EC code:
 

 OLPC is proud to announce that the XO-1.75 embedded controller will
 have an open codebase (with a small exception, see below).  After much
 behind-the-scenes effort, EnE has agreed to provide us with a public
 version of the KB3930 datasheet and is allowing our new code to be
 made public.

 The code is not available yet due to a few chunks of proprietary code
 that need to be purged and some other reformatting.  A much more
 detailed announcement will be provided once the new code is pushed to
 a public repository.  The code will be licensed under the GPL with a
 special exception for OLPC use.

 The exception is because EnE has not released the low-level details on
 the PS/2 interface in the KB3930, so there will be some code that is
 not available -- relative to the codebase this is a very small amount
 of code.  The GPL licensing exception will allow for linking against
 this closed code.  We're going to investigate ways to move away from
 this code in the future.  (As far as we're aware, this will make the
 XO-1.75 the first laptop with open embedded controller code!)

 Multi-touch Sugar:
 ==

 We've begun working on modifications to Sugar to enable touchscreen
 and multitouch use (the XO-1.75 will have a touchscreen, as will
 future OLPC tablets based on its design), and we'll continue to do so.
 The first outcome from this work is Sayamindu Dasgupta's port of the
 Meego Virtual Keyboard³ to Sugar -- you can see a screencast of it in
 action here⁴.

 It's an exciting time for software development at OLPC.  Many thanks
 for

does that mean that XO-1s are still being produced and the production lines
will be updated to include the new bottom half? Or is only going to produce
new XO-1 bottom halfs as spare / replacement parts for deployments?

Any ideas whether the non-membrane keyboard will be available in single

Re: [Sugar-devel] unable to share Activities on XO-1.5

Out of cursiosity:

Has anyone done real and actual testing of collaboration on XO-1.5s with
the/a current operating system version? Particularly testing that goes
beyond 2 or 3 XO-1.5s...

I was certainly very surprised to hear about the issues that Adam and the
rest of the DC Book Sprint team encountered when trying to take these
screenshots for the collaboration section of the guide.

Last but not least: Can we expect collaboration between XO-1s with 802 and
XO-1.5s with whatever OS it will be shipped with to generally work? Or are
there any major differences in the collaboration stack inbetween those two
versions that could cause issues?

Thanks,
Christoph

Re: New F11 for XO-1.5 build 61

 Compressed image size: 705.43mb (+1.50mb since build 60)

 Description of changes in this build:
  * add Q3A24 to build (#9889)
  * fix Sugar five-character nickname limit on ad-hoc networks (#9807)

 Package changes since build 60:

 -bootfw-q3a23-1.unsigned.i386
 +bootfw-q3a24-1.unsigned.i386
 +sugar-0.84.9-1.fc11.1.i586
 -sugar-0.84.9-1.fc11.i586


Maybe I missed this in the earlier XO-1.5 builds but upon installing build
61 I was surprised to see Restart again in the main hover menu. Wasn't it
decided awhile ago that removing that option from that menu was a good idea?
(IIRC #1206 dealt with that very topic and it was solved in Sugar 0.86 -
seems like a reasonably small change to consider for the final XO-1.5 builds
as well)

Cheers,
Christoph

Re: 8.2.2 Beta-1 test request

I also installed 802B1 on one of my XO-1s today and played around with it

=Touchpad=


Of the two XO-1s (both with the ALPS touchpad) I have around here I chose
the one where the touchpad issues have been particularly annoying. In fact
it was so bad that even after 5min of failed attempts I couldn't manage to
even draw a single half-decent spiral in Paint on 802.

802B1 hasn't really helped there as very often the cursor now freezes
completely and even after waiting for 20 seconds or doing a manual
re-calibration I can't get it move more than a couple of centimeters. If I
understood the issues correctly 802B1 now simply disregards suspicious
looking data coming from the touchpad and it seems like that touchpad is
particularly affected so basically now data makes it through at all.

= Kernel =


Didn't run into any issues regarding suspend / resume.


 = Wireless: Associating to Access Points and debugging =


I've had issues on 802 connecting to my WPA home-network every now and then
and 802B1 seems a little more reliable there (but that's more of a gut
feeling).

= Startup / shutdown =


Yes, shutdown is definitely quite a bit faster compared to 802!


 = OS version =


Works as advertised.

= Update your Activities? =

 The you must update your activities dialog on first boot is gone! It
 will only appear after a major upgrade (not a minor one).


Yep, the dialog was gone, updating a bunch of activities worked just fine.

= Do the activities work? =

 Try out the activities included. Did I break the OS so that any
 activities are failing?


With the pre-installed Record-59 I ran into lockup issues similar to what
Gary has reported, the latest record (64 I believe) works fine.

Measure-27 doesn't seem to do anything, I can't get it to display any input
and after some random button clicks it tends to freeze so badly that only a
Sugar restart helps.

Christoph

 Hi,

http://wiki.laptop.org/go/F11_for_1.5
http://dev.laptop.org/~cjb/f11-1.5/os49

 If you have a 1.5 B2 (which almost everyone with a 1.5 machine does)
 and are using os47-os49, you'll need to turn off Automatic Power
 Management in the Sugar control panel, else the wireless device will
 go away after the first suspend and not come back until the next
 reboot.

 This doesn't happen on B3s, and we can throw a quirk into the kernel
 to fix it for B2s.  We'll announce when there's a new build with a
 kernel that allows suspend/resume testing on B2s, but in the meantime
 you should avoid suspending them if you care about wireless.


Mmm, I just tried updating my machine and it's been stuck at Performing
incremental rsync. for at least 20 minutes now. Someone had mentioned that
the first person to access an update triggers some sort of procedure on the
server but I wouldn't expect it to take that long. (And yes, I had
disabled Automatic Power Management before starting the update.)

What also seems odd is that even though Sugar's battery monitor still shows
65% the power LED turned red during the update process. Now that I've
connected the AC adapter the power LED is indeed orange but the tray icon
still acts as though I'm running on batteries.

F11-for-XO-1. Sharing and connecting Distance-17 worked fine however once I
press begin measuring distance on both of them I'm left looking at the
Recording sound from each laptop message on both machines and the XO-1.5's
mic LED being turned on for at least 10 or 15 seconds. But there's no sound
being played on the XO-1 (audio playback in TamTam works on both machines).

Mmm, and after about 10min of use now I'm seeing a really weird issue where
the detail view of the Journal entry is simply one big gray canvas with only
the toolbar icons and the back button being available. Additionally on the
main list view I can't get any popup menus (to copy/send Journal entries,
etc.) anymore. FWIW datastore.log is filled with entries looking like this
one:

1259718621.729821 WARNING root: Unknown term(s):
dbus.Dictionary({dbus.String(u'limit'): dbus.Int32(5, variant_level=1),
dbus.String(u'order_by'): dbus.Array([dbus.String(u'-mtime')],
signature=dbus.Signature('s'), variant_level=1)},
signature=dbus.Signature('sv'))

Good night,
Christoph

 Hi Christoph,


Hi,


The power-management kicks in as expected however to wake the XO
up again you actually have to press the power-button, hitting a
key or moving the cursor doesn't wake it up (as it does on the
XO-1).

 I think this is fixed in the new OHM in os48 -- could you retest,
 please?  (Fixed using the same dance I described, but done
 programmatically inside OHM.  Yuck.)


Okay, will update to os48 either tonight or tomorrow and report back my
findings.


Also power-management doesn't seem to be activated when closing
the lid (at least the power-LED doesn't indicate that it is).

 This one's only a problem with B2s.


Good to know, thanks a lot for the information.

Cheers,
Christoph

 Bingo. It actually supports an rpms dir. Drop something there and go.

 And I am looking at using the same curl trick that we use in the F11
 builds to grab activities from ASLO (latest vs specific version).


Martin,

all those proposed changes and bux-fixes look great, based on my experiences
with the small Austrian pilot project I'm particularly excited about
anything related to activity updates, touchpad behaviour and maybe I can
even get around to play with image-builder and do some more customizations
at some point.

Thanks a lot for all your hard work on this! :-)

As mentioned on the other thread waking up on keyboard and touchpad input
now seems to work just fine.

However now pressing the power button only seems to turn off the screen
without actually going into suspend because after about 5 seconds the screen
comes on again and the power LED stays on all the time.

Another observation is that the dimming of the screen kicks in after about
20sec of inactivity but it takes another 5sec before suspend really happens.
I for one find these timings slightly confusing and don't really see any
advantages of having two seperate intervals for those two operations. (But
maybe I'm missing something here...)
