RE: Re-install os885 on XO-1.5 error
Thanks again James. The md5sum was OK so I reformatted the USB stick and tried again - and no error. I have done this so many times before on XO-1 but never seen this. So the first time I tried on XO 1.5 it happened. I must remember the old adage, if the car doesn't start maybe it has no petrol...

Please run the heat spreader test on this unit: ok test /switches If the heat spreader does not contact the CPU properly, the temperature can rise too much during installation. If the temperature is too high, the CPU can pause, or make mistakes. Significant gaps, blocks staying gray, are normal, and nothing to worry about. These blocks don't need to be written, so the .zd file does not write to them. This saves on downloads. The error "Wrong expanded data length" means that the file was not correct on the USB drive, or the USB drive could not be read. The task was aborted. Things you can try: * check the file using md5sum, see http://wiki.laptop.org/go/Download#Verifying * try a different USB drive, * don't use a USB hub, * disconnect any other USB devices, * try a different port on the laptop, * upgrade the firmware; you are using Q3C07, but Q3C08 contains a fix for USB drives with embedded hubs, and Q3C13 has a fix for USB drives with unusual partitioning. Q3C15 is the latest version. That the XO starts up OK afterwards is not a valid test, since it would likely have the same build already installed. No logs are kept of firmware operations, so you won't find any evidence; you have to repeat the problem and gather data that way. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hello, Apologies if this issue has been covered already. I am trying out 12.1.0 on the XO-1 and ran into an issue; to install additional set of activities on class sets of XOs we have been using the customization stick method as per http://wiki.laptop.org/go/Customization_stick which involved expanding customization-2.zip onto root of a USB stick, copying .xo files into the bundles folder and then with USB stick inserted, starting the XO with the lower and right games keys pressed. I can't get it to work on an XO with 12.1.0 - it shows briefly a process error before powering off. Perhaps the instructions on the wiki page above are outdated?

Collaboration XO-1 with XS
I have noticed when using the combination XO-1 build 883 , Sugar 0.94.1 and XS-0.6 that collaboration for registered XOs connected to the XS network is unreliable. After doing some collaborating sometimes the populating of the neighbourhood views becomes unreliable and shared activities are not displayed on other XOs neighbourhood screens. Also, when hovering over some XOs which are displayed on neighbourhood view, the name is not shown but instead a long text stream. This has been attempting to disrupt teacher training I am conducting but we work around it by for instance using "discard network history" which seems to help. I am copying to both lists as I am not sure where the problem lies. Any advice appreciated and apologies if some of this has been covered in past discussions, if so just a referral would be most appreciated.

The package names are the names of the packages you want as discussed in step 2 above. I really feel we are going in circles here.

I have tried to install media codecs on an XO-1 running 11.3.0 so that we can play FLV video files directly (from a flashdrive, school server or network location)., in either Sugar or GNOME. I had trouble getting it work using the instructions at http://wiki.laptop.org/go/GStreamer#Totem_plugin - I think it is outdated. After some research and trial and error (lots!!) I have it working, some using XO-1 may find useful The below works on an XO-1 running 11.3.0 freshly installed. It works in Gnome using Totem/Movie Player and in Sugar using Jukebox Activity. It plays mp3 audio and FLV video OK (such as the Khan Academy collection, which we have loaded on the school servers in project schools) We also add the Flash plug in for the browser and disable "click to view". This allows embedded flash animations and FLV videos accessed with Browse, Youtube, etc to play with good performance. Note that Flash version 11 is much better than v10. So bringing it all together, I reproduced the above using the following. - XO-1 running 11.3.0, fresh install - In Gnome view in a terminal, as su - wireless Internet connection yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noa rch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stab le.noarch.rpm yum install -y gstreamer-plugins-ugly yum install -y gstreamer-ffmpeg rm /home/olpc/Activities/Browse.activity/agent-stylesheet.css rm /home/olpc/Activities/Browse.activity/clickToView.xml navigate to the flash rpm and run rpm -Uhv flash.rpm where flash.rpm is the Flash verion 11 RPM for Linux 32 bit from Adobe. Questions 1. Is the above the right way to do it, if someone with more Fedora experience than I can verify.. 2.

RE: [Sugar-devel] 883 on XO1
Thanks to James, we successfully repaired the download. A very neat solution that I had not realised was possible. For others that may find it useful, we used the Linux split command (I used the XS) to chop the faulty download into 128 small chunks of about 5MB each and then did checksum with md5sum on each, identified the errant chunk, which I then downloaded and used cat command to rejoin them. I now have the 883 build for the PNG schools. Many thanks James and Alec David -Original Message- From: Richard Smith [mailto:smithb...@gmail.com] On Behalf Of Richard A.

Having builds available via bittorrent or some other p2p tool would be very useful when the dev team in in China. Bandwidth at the factory is limited on per IP basis. If the builds were available via p2p with swarming then the team could peer each other and we all would download chunks in parallel.

883 on XO1
Apologies if this has been explored before, I have not been able to stay current. I am posting on both Sugar and OLPC dev lists. I live in Solomon Islands, where we have very poor Internet access and downloading is affected by satellite latency etc. I just tried to install the latest stable for XO1, advertised as 883 / 11.3.0 on one of my few XO-1s. I have not had access to any higher versions of the XO and am working with a programme in PNG which has XO-1s. I downloaded the image (BTW in Solomon Islands that cost me USD 85) using a download manager Star Downloader (to protect me against Internet drop outs). It downloaded with no errors reported. I then tried to install on my XO using a flashdrive as per the usual 4-game key method. On first attempt it failed during the part where you see the progress indicated graphically with the memory grid in green yellow and black. It says: 4ce Bad hash for eblock# 4ca Your USB key may be bad...please see http:/wiki.laptop.org/go/Bad_hash The diagnosis is that it's either bad flashdrive or bad download. I tried 2 other flashdrives that have successfully been used before, and same result at same place. So i conclude I have just thrown USD 85 down the toilet.

Memorize Game sharing a Created game
Hello, I would like to understand the correct procedure to share and invite a Memorize game that has been created on an XO. Whenever we try this it is very difficult to make it work. Using XO-1.0 / 8.2.1 and Memorize-34 1. Create, name and save a game adding matching pairs of photos from the journal, matched to words (text). 2. Try to invite or share with others. On the XOs that have joined, the game area remains blank (black) and nothing seems to load further 3. We tried uploading to the serve r (site files) and pre-loading the game on other XOs and retrying. No result I have done this successfully in the past (i.e. transfer a newly created game to others) but cannot reliable replicate. It would seem to be a standard sort of thing to do with Memorize so is it the wrong version for the build/XO that we are using? We also note that when you save a Memorize game it does not give it a file extension/type icon and thus does not load from the journal - you have to "load" the game from within Memorize. Have we lost something in the mix with that too? David Leeming ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Update procedure 10.1.1 XO1.5
Hello, I am helping with a deployment expecting XO1.5 with 10.1.1 but we have not got our hands on any of them yet. It is not clear to me, if the "flashdrive reinstall" method remains the same for activitie as it was for the 1.0 I.e. I can see that one reinstalls the OS by starting up the XO-1.5 with a flashdrive containing os204.img and fs.zip, holding down the four game keys; if you want to install a bundle of activities at the same time, what is the procedure (for locked XOs)? With the 1.0s we have been preparing the flash drives with a boot and bundles folder and a file customization-2; the XO automatically restarts after flashing the OS to install the activities in the bundles folder. What is the equivalent with the 1.5/10.1.1? How does gnash on the 10.1.1 release compare with previous versions, do we still need to install Flash 10+ to view stuff like youtube and flash animations?

It may make sense to enhance the makefile to have a "make clean" target. If the makefile tleaves originals and work with copies such a target shouldt be possible. Also "make clean" uses a common target for make so the concept would reinforce common programming practices. i.e. something like. # make -f xs-config.make named-xs.conf and # make -f xs-config.make clean Another tool to invest in might be "etckeeper" which makes sense for servers of any kind.

[Server-devel] Latest on capacity of the school server
Hi from a small island in the north Pacific - Kosrae (FSM). Here they are going for a complete programme with all graders 1 to 8 . That takes in six Elementary Schools (the US system is used here) the largest has 3 streams, 24 classes and about 500 students. The school is arranged in a large U plan form in two floors/storeys. What experience do we have on the latest thinking about the capacity of a single server? Here in Kosrae they have good 24/7 power availability and air-conditioned offices in five of the schools. We can therefore specify powerful machines, even dedicated server models if need be. If we segregate off each of the 24 class groups, would a single powerful machine server be able to handle 500 students in 24 classes (courses) simultaneously? (of course in practice that maximum load will rarely occur). I suspect we don't have a definitive answer and I would like to develop a strategy with the ICT people here. Perhaps to plan for multiple servers in such a school and then progressively introduce them in response to the way they perform. Any feedback on good techniques or references/guidance on the wireless infrastructure would also be appreciated. In the larger school, we have two floors, 12 classrooms per floor, in U-shape layout. I would place one AP per classroom spread evenly around the school - that would be about 20 students per AP. The APs set up all on eth1 LAN with the same SSID. If we use multiple servers, we'd use different SSIDs for each. I have not deployed such a large site before so any comments on this would be appreciated. (2) In PNG SDP's project in North Fly, PNG, we are using small "eboxes" because of the need to run on solar power. We have deployed one full-campus wireless/server installation, quite a small school (160 total, 80 users in the first roll out). These users are divided into 3 class groups, as Moodle courses. So they are segregated. We have had feedback that it still gets slow / congested when all users are on simultaneously (80 users in 3 separate courses). I don't have an opportunity to visit the school and quickly inspect the servers logs etc, so I am not sure of the cauase, i.e. the small capacity of the "ebox" or other cause.

RE: Educational XHTML Editor Educational Game Maker
Mike, I have followed eXe Learning since it started, developed by Wayne Mackintosh who later on, of course, created the WikiEducator and is a leading champion of OERs. I can instantly see that eXe Learning if installed on the XOs would be a very useful tool. Very easy to train teachers to become productive quickly, compared with, say, online wiki work, which is not always an option (yes we can install mediawiki on the XS but I think eXe Learning has specific advantages in some areas). It is very well targeted technology, thinking of the OLPC deployments in which I have been involved. As an example, in a distance learning programme here in Solomons in 2007 we converted examples of teacher training resources into online format using eXe Learning, in order to demonstrate simple first steps in e-learning to the Ministry. A junior officer with only basic office computing skills was able to migrate the entire RTC teacher training manuals to online with limited supervision - and she enjoyed it too! Of course, the resources produced with eXe Learning are HTML based which are easy to install in public folders on the XS. eXe Learning can also output SCORMs which can be loaded into the XS's Moodle as appropriate. If we had access to an eXe Learning activity I would immediately incorporate it into the teacher training that we do in Pacific Islands deployments. Empowering teachers to create and share resources is always a key component of Level 2/3 training, linked to curriculum integration. OERs have massive potential for the Pacific. Educators have repeatedly called for more regionally relevant and localisable curriculum related content, and empowerment of front line teachers to create OERs is the way to scalability - freeing up the dependence on overworked curriculum departments locked into traditional closed authoring approaches with long term donor programmes. Resources created with eXe Learning by teachers with XOs will therefore have a wide currency beyond the OLPC project areas which are still only small scale. They can be shared and used freely. So, I will watch this thread carefully. I would like to help, if not as an active team member on the coding, in other ways. What is the status of this, can we expect an eXe Learning project for Sugar and the XO? One requirement would be to be able to create a resource using the "eXe Learning" activity, name and save in journal, then to be able to upload it to the server so that it is installed as a public folder (or via "site files" etc) but without any difficult command line work needed on the server. So needs to be coordined with XS-devel.

Though Scratch and Etoys are great for simulators for many common educational interaction formats (e.g. assemble objects, click in place according to hint in order, memory match, hangman, sorting items etc) using such tools can be quite awkward. eXe Learning was created as a GUI educational XHTML Editor with support for fill in the blank question formats, multi choice, multi select etc. I have created plugins for Place the objects / label (e.g. assembling parts / labelling a diagram), Click in place according to a hint, sort objects, hangman, memory match, moving object speed answer (e.g. Tuxmath) and sort. The output is generated as HTML / Javascript which can run online or offline. I've also created a plugin for embedding Scratch using the Scratch Java player with an option for the user to download. There are many repositories of open content; however many of them fail to harness the potential of ICT as an interactive medium. Hopefully further lowering the barrier can help to create more. This can make it far easier to turn existing open static content into interactive educational content. Compared to conventional Javascript / Flash / EToys development this dramatically increases the amount of educational interactive content that can be produced by given teams in a given amount of time. It also can help make creation of interactive educational material far easier for educators by templating the kind of interaction they would like to produce and allowing them to just plug in the questions, answers, images, options of the game etc. For many parts of the curriculum the best course of action can be to embed already created Scratch simulators from the Scratch website (e.g. physics sims). With eXe Learning + plugins one can produce a complete interactive package that opens in the browser. I am hoping to develop a roleplay and generic simple simulator creat

Actually I loaded it onto and Acer Aspire One netbook. When I connected wirelessly to my XS server access point, my IP was the standard 172.18.96.* and after changing the default server address under / My Settings / Network, I registered onto the server with no problem. Actually, this was the first "XO" to ever register onto my server, so it was given the course creator role. I'm not sure why your PC was assigned a different network. You should check to see how DHCP was set up on your wireless connection. Or maybe someone here will have an explanation. Bottom line for me right now is that my netbook is connected wirelessly and registered as if it was an XO (running Sugar of course).

Extracting and analysing journal data
Hello, In the Solomon Islands a formal evaluation is taking place this month of the 3 trials http://wiki.laptop.org/go/OLPC_Solomon_Islands The independent evaluator wants to extract and analyse journal data. The schools do not have servers yet so there is no data there, it needs to be done by pulling the data off a representative sample of XOs and then being able to analyse it with spreadsheet or database tools. Please can anyone advise if they know the best way to do this.

DNS
Hello
I have a need to use an XO with a USB-Ethernet adapter and an Internet
connection with no DHCP that requires me to set the network up on the XO.
I can easily do the IP and netmask with
/sbin/ifconfig eth0 [IP] netwmask [mask]
and the gateway with
/sbin/route add default gw [GW-IP]
Can anyone tell me the best way to set up the DNS? I tried the following in
rc.local which results in me being able to ping hosts on the Internet but
DNS is not working, have I made a mistake?:
addNameServer ()
{
ip="$1"
file="/etc/resolv.conf"
result=`cat "${file}" | grep -c "${ip}"`
if [ ${result} -eq 0 ]
then
echo "nameserver ${ip}" >> "${file}"
fi
}
/etc/init.d/NetworkManager stop
/sbin/ifconfig eth0 [Static IP] netmask [mask] up
/sbin/route add default gw [Gateway IP]
addNameServer "[DNS IP 1]"
addNameServer "[DNS IP 2]"

[Server-devel] Content in Moodle
Hi, I would like to understand the vision for content management on the server using Moodle. Up to this point (with version 0.4), we have been using browsable folders of HTML content (including expanded SCORMs with customised index files, for instance from the Wikieducator's IMS package export utility), and also PDF material. Both work fine. HTML is more flexible and easier to port - PDF material needs reformatting for the XO,to make it more readable. I am fairly familiar with Moodle as we have one in our DLCP project www.schoolnet.net.sb but the focus is on "courses" not "content" so I was wondering how this fits with the OLPC content vision, collections and the rest. On another minor point, I want to provide the option to go to browsable folders or moodle on first acess to the school server. So far I have done this by editing the who.php file and adding a link "click to browse folders". But maybe I am missing something that can be better managed by Moodle. I would also like to see a collaboration platform (we used the JoinNet Home Meeting one with DLCP, using National Sun Yat Sen University of Taiwan's CCC LMS server). That would combine video chat with sharing a whiteboard, with ability to post slides, annotate them etc. Also, an offline wiki on the server would be useful. Any ideas would be appreciated.

Touch pads
Some feedback on touch pads. I returned to the PNG trials school of Giare last week to do some training, and noticed several of the XO-1s (received in June 08) and running version 8.2 suffering very badly from the touchpad problem. One boy's laptop was almost unusable. We tried chalk, the 4 finger salute, rebooting, etc. Despite this, he managed to do the attached with Paint in the morning when it was cooler. During the afternoon the temperature must have been 35 deg C and 90% humidity. Is this problem likely to be solved with software updates?

RE: Touch pad
You wrote: We (the techteam) have some questions: - Are there any XOs for which mouse performance is worse since the kernel upgrade? - What are the average environmental conditions (humidity level, dust, temperature) when you are testing the new driver? Please answer at your leisure. ___ My answer: So far, I have successfully installed the updated kernel on my B4s but not on the secure G1G1s as that requires a different approach that I have not gotten my head around. I used the updated B4s as my "teaching laptops" at the Batuna trial (see Youtube link at http://wiki.laptop.org/go/OLPC_Solomon_Islands). I did notice some misbehaviour. I can't quantify it and it seemed less of a problem than before. As far as I could tell, the cursor sometimes became very sluggish but did not jump around as before when the issue was observed. The 4 finger salute to recalibrate the touchpad worked well. So my impression is that there is still some misbehaviour of the touchpad but it is improved. This is however based on only a few days experience. This was in the Solomon Islands, where it is often above 90% humidity and 32-24 degrees C. Very bad conditions for the touch pad!

The US adapters supplied with our batch of gifted XOs (much appreciated) is however a disaster in PNG where they use Australian 3-pin type - they have pins aligned so that each adapter covers the adjacent outlet in a powerboard, and in any case 2-pin adapters are unavailable and 3-pin types need to be forced as they require the 3rd pin. An 8-outlet powerboard can only take 4 precariously arranged adapters, there s a safety issue. This will of course be solved when we get gang chargers and/or the daisy chain charge devices.

Issue with activities using sounds and invite and power adapters
In trials in PNG I have come across an apparent issue with build 703 / activities as of date. If you run the Measure activity and then follow with the Record, the screen (digital camera output) is blank. If you run two activities using sound (TamtamMini and Speak for instance), you may find that one has no sound and the XO needs rebooting. If you have a lot of laptops (i.e. we had 40+ in a small area, we were in a classroom and then in small groups outside), the invite function is not reliable - you invite someone but no icon appears on the activity bar of the invited XO.

RE: Upgrade G1G1 using autoreinstallation method
Hi John, Sorry for silence, I am just back from a trial deployment in East Sepik (wiki will be updated later today) See feedback from OLPC Australia: (note that setting up an XS is not a short term option in our trials in PNG, as there is no permanent power supply a the school) >>> Just wanted to give everyone an update. I bought a DLink DWL-2100AP which is what David and Ian are trying to implement for their XO rollouts. We found that we could not get DHCP working on the AP at all for either an XO or for an IBM laptop running Ubuntu. We tried several different firmware versions (although the AP is seemingly locked to European firmware and we can't use the US ones) and the only way we could use it was as an AP that forwards DHCP requests to the network. >>> We've spent about 4 hours today trying to troubleshoot the issues and I am unfortunately going to have to recommend that the APs be plugged into a network which plugs into an XS server for DHCP to get the XOs connected. David, where you can't have an XS server you could always buy a different AP or other DHCP allocation device per site for DHCP resolution as these APs seem to be inappropriate for the job (at least the Australian ones). >>> As per my email to the devel list, we purchased an identical AP and mostly duplicated the problem you're seeing, but were unable to find a fix. >>> We tested different firmware versions and different settings. Googling for the issue was interesting as most people simply gave up and used these APs as wireless bridges. Ultimately the clients will associate with the AP fine, but they simply will not get a DHCP address and there are a lot of messy log messages that don't help at all. >>> I think setting up XS server at the sites (where possible) and turning DHCP off on the AP is the most sensible way forward. I know this contrasts slightly with David's experience but this is what we found. Let me know if you find anything else. >>> If you want me to source APs that do work both for the future and perhaps to act as the DHCP servers for your existing sites, please let me know. A disappointing outcome but with a bit more notice we'd be happy to help recommend and source better hardware in the future. We literally knew about Ian's trip through Australia and the purchase of the APs the day before he arrived. >>> it seems these APs are not highly regarded and apparently in particular have issues in high temperature conditions, so you may have worse issues ahead of you :/ Please let us know what we can do to help. -Original Message- From: John Watlington [mailto:[EMAIL PROTECTED] Sent: Tuesday, 17 June 2008 5:58 a.m. To: David Leeming Cc: John Watlington; 'Bert Freudenberg'; [EMAIL PROTECTED] Subject: Re: Upgrade G1G1 using autoreinstallation method On Jun 14, 2008, at 6:09 AM, David Leeming wrote: > Hi John, > > To see if we could duplicate our problem, we tried with another AP: > We have > a VSAT set up near the village where we are deploying a trial with 50 > children in PNG.

RE: Upgrade G1G1 using autoreinstallation method
Hi John, To see if we could duplicate our problem, we tried with another AP: We have a VSAT set up near the village where we are deploying a trial with 50 children in PNG. It has a reliable wireless AP and you can associate both "grown up" laptops and XOs no problems. The XOs will then see the Internet and also other XOs and the activities will share OK. This AP has a DHCP server on the wireless side. In fact, there is no other as the AP connects straight to the VSAT modem, which does not have DHCP set up, via a switch. If one pulls the cable out on the LAN side of the AP the XOs cease to share and quickly drop out and look for the mesh. So, this duplicated the problem I described. I am now told that a jabber service is needed to keep the XOs interested and reliably collaborating, that maybe is the cause? Do you concur? I do appreciate your help...

Thanks - solved. It's all there on the wiki, yes (blush). We have a lot of time pressures imposed by the political realities here, with 20+ countries each with their own government and process to go through, etc. I do appreciate your help! Do you also know about access points, it was stressed at the Countries meeting in Boston that 30+ XOs in one classroom do not collaborate very efficiently and the preferred method is to use an AP to enable collaboration/sharing in the classroom, even if there is no Internet access. We have had some D-Link DWL2100 APs sent to us for this purpose and what happens is that if there is no Internet connection the XOs do not associate themselves persistently with the APs but "hang up" and go looking for the mesh.

Downloading large updates and builds in PNG
Hello, Is there a better way of making new builds and updates available? I am starting a deployment of XOs in Papua New Guinea this week and have just heard of the new G1G1 update (build 703). I may not use that immediately but need to appraise what is involved in updating by trying it out. However, downloading a 300MB file in a place like this is very difficult. It's the same in the Solomons. If you are relying on the monopoly ISP your connection will be variable and unreliable and even where wireless broad band is now being made available, it costs about USD 50c per MB in the hotel I am staying at. A quarter of the way into the download I loose my connection and the download is lost (with the money). Is it available on an FTP server which I think is more reliable? Can it be made available in smaller chunks? David Leeming ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Flash is too full
I have an XO-1 that has stopped booting correctly after I tried to install some large activities from a flash drive. I cannot make a clean install because it has firmware security enabled and I am unable to interrupt the boot without the developer key, which I don't have. I can't create one because it doesn't boot. On boot, the normal screen is an XO symbol, which then spins 360 degrees tracing out a circle of dots. On this one, it slows and crawls to a stop before completing the circle. If I leave it running it gets to a state where a white screen flashes up (as if Sugar is beginning to start) then flashes off and the command lines etc are seeneventually it says it is disabling for minutes due to "respawning too fast" and I have a window when I can log onto the back end / shell as root and type commands. But not sure what to do! David Leeming ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I am interested in how to localise the XO for our Pacific Islands region in terms of the Speak activity and speech synthesis generally.

Changing keyboard layout
Hello, I have some B4s with what I assume to be Spanish of Portrugese keyboard markings. The shift key is labelled "mayus". We intend to use these with English-speaking children. I am able to change the Sugar language to English by editing /etc/sysconfig/i18n such that the line LANG="es_AR.UTF-8" is changed to LANG="en_US.UTF-8" I can also change the /etc/X11/xorg.conf file as stated in the Wiki section on customising the NAND image. But the keyboard layout remains the same; i.e. if one presses the underscore key, one gets a forward slash - many of the non-alphanumeric keys are also mixed up. Can anyone suggest how I can have both English language and the correct keyboard configuration on these B4s. I am sorry if this might be quite trivial but I can't easily locate the solution.
