==Image about the World Summit in Tunisia, showing Nicholas Negroponte and Kofi Annan when presenting the laptop==
Hello, I am writing an article in the german Wikipedia on the "100-Dollar-Laptop" aka "Children's Machine" (link: http://de.wikipedia.org/wiki/100-Dollar-Laptop). I would like to add an image showing Nicholas Negroponte and Kofi Annan in Tunisia on the World Summit. Unfortunately on flickr there is no photo, which is compatible zu the gnu-licence. Only Creative Commons 2.5. with the right of commercial use and of course the gnu-licence are allowed to be uploaded in Wikipedia.


</noinclude>
Do you have such a picture in your portfolio? Can you upload this picture with compatible licence on Wikipedia?
= New questions =
My OLPC stucked off after starting up and please also guide me that from where i can get
new charger for my olpc?


== Question ==
In my opinion such a picture would have positive impact on OLPC's image. If you google for "Children's Machine" the german Wikipedia-article has the best page rank. You can contact me on the german Wikipedia, search word "Betbuster".
We are planning to help OPLC but we need to check the Financial Statements of the organization. Does somebody know where can we get this information?


:From OLPC directly, or the government or other regulators. I don't think you should rely on what contributors to a community Wiki might tell you ... that's not a rigorous method. --[[User:Quozl|Quozl]] 03:23, 13 February 2012 (UTC)

== School Gateways ==
== Question ==
I turned on my OLPC but it didn't show anything.What do I do?


:Check out [[Keyboard freeze fix for os 650-656]] it might be your problem. Hard to say, unless you can give some more information, like when you last used the XO, whether the power indicator turns on, whether the display backlight turns on. --[[User:Quozl|Quozl]] 21:04, 30 August 2011 (UTC)
I've looked around the site for a while and cannot find much about gateways at the schools. Can somebody tell me about the connectivity to the internet for the whole mesh network through gateways at schools? I'm especially interested in what the power requirements will be for a gateway, because I'm hoping to find out how hard it would be to set one up in an area where there is no electricity. Thank you!
== Question ==


how do download windows xp on to my olpc xo and how do you access your downloads
:The OLPC networking concept is not Internet-based. We assume that there will be no Internet connectivity and no Internet gateways. The laptops are being deployed into countries which do not have a lot of native-language content available on the Internet. The networking focus is to make sure that the laptops will be able to communicate with each other over a larger than normal area, and that they will be able to communicate with resources in the school. In most cases, these school resources will not be Internet gateways but will be more like a cross between a library and an FTP site with content that kids can download to their laptops. Of course some schools will have Internet access and may copy Internet content for use by the kids, but the laptops are not intended to be used for direct Internet surfing.


: There is no way to get Windows XP for your individual OLPC. Microsoft does not make it available to individuals, and OLPC has nothing to do with that.
::OLPC is not interested in taking on the added burden of Internet connectivity for dozens of countries, but others are, including [[OLPC4USA]]. See [[Internet]] for more. --[[User:Mokurai|Mokurai]] 15:30, 26 December 2006 (EST)


== Downloads ==
:In regard to your questions about power, you may wish to read the [[Battery and power]] page for tips.
How to access your downloads?
: If you download things on the OLPC, they should show up in the Journal, which is one of the Activities that's always running. It looks like a little spiral notebook. You can also open the journal by pressing the "magnifying glass" icon in the upper-left hand part of the keyboard.


== how do you start your downloads ==
== Technology innovation is moving at a very rapid pace ==


I downloaded adobe flash player but i still can't watch my videos i know you go to journal and the file and click start but it doesn't work.
How are you guys planning for the future. How are you guys preparing for the technology currently planned to be used inside the laptop becoming absolete. What is your turnaround time between parts going into production and actually being distributed to the people?

== your disk is full ==
==Maximum Altitude Spec==


What should i do if i go to my record activity and it says my disk is full?
According to the [[Hardware specification]] the ''Maximum altitude: -15m to 3048m (14.7 to 10.1 psia) (operating), -15m to 12192m (14.7 to 4.4 psia) (non-operating''... would it be possible to operate (safely) above that altitude? After all, in the Andes (and I'll assume the Himalayas) many people live higher...

== How do I chat with other people in the world? ==
==Usability and User Testing==


My xo is hooked up to the internet but I still don't know how to chat with other people in the world could you tell me how please?
There is very little public information about requirements gathering, usability and user testing. In other words, how do you know whether the OLPC (i) will meet your users' needs and (ii) is easy enough for them to use? Have the target user groups been characterized? What ongoing plans do you have for this?
: First connect to a [[Jabber server]] or your local school network. Then you can see other people on your network and will be able to chat with them.
I`d Like test the OLPC in Argentina, Please contct with me to know how.
: You can also download [[XoIRC]] and chat with people using that activity. 02:34, 17 December 2009 (UTC)
Thanks.
:As far as I know, there are two local groups in [[OLPC Argentina|Argentina]] with test boards (don't know if anybody has the 2B1/XO prototypes though). They are [https://www.ututo.org/www/modules/downloads/downloads.php?ID_downloads_category=21 Ututo] and [http://tuquito.org.ar/olpc/index.php?title=Portada Tuquito]. I know [http://www.ututo.org/ Ututo] had some explicit arrangements to let other people use/test the boards. If anybody knows about other groups (or about any local XOs) please let me know (or post in the [[OLPC Argentina]] pages. --[[User:Xavi|Xavi]] 07:23, 6 December 2006 (EST)
== Downloads ==


How do I download music on my labtop?
==Deployment Criteria & Metrics==
: Click on a file to download. Then open it from your [[Journal]]. Alternately, install an activity like [[Jukebox]].


How do I download Doom?
Although these issues are basically 'national' prerogatives, is there anything being done at the OLPC level? In many countries, 1 million laptops will either be too little or too much. All along, before, during and after the deployment they should be able to assess the result of the effort (metrics), be it to keep the course, or change things, or try new things, etc.
: The page about it is titled [[Doom]]. 02:34, 17 December 2009 (UTC)


== Reset settings ==
:We do not believe there is such a thing as too little. In countries where 1 million laptops is too many, we won't be able to do an early deployment, but we do expect that after a few million units are in the field, there will be other organizations who will deploy smaller quantities to smaller countries, such as many island nations. In fact, Libya has announced their intention to buy laptops for some poorer African nations.

::I think that spanish speaking latin american countries do fit in a gray-zone there; there are many that individually would have to wait for later stages, but together they could probably put something - ie: central american countries.
: From the [[Sugar Control Panel]], update your "About me" settings, and restart. 02:34, 17 December 2009 (UTC)


== Viruses ==
:As far ans metrics are concerned, we take that very seriously both in the design of the laptops and in the whole deployment process. We are constantly measuring, analysing and making course corrections based on the data. We will continue to do so.


How Do I erase viruses from my xo
::Seriousness is good. Transparency too. :) I've somehow managed to reach the [[Pilot Projects#Diversity Matrix]], which I find a bit shallow and unstructured for my taste, so I'm assuming that more structured guidelines are being thought out, planned and to be published, right? After all, as the proposers of the idea, the performance analysis and other measurements should be your domain of expertise. For example, which population segment is known to make the most out of the laptop experience? Is income considered a (key) factor? People with very-low, low, medium, high, or very-high income are 'all equal' or they somehow 'profit' differently in respect to their original educational levels? Under all circumstances?
::I'm well aware that these are mostly unanswered questions (I'm not looking for an answer here) and will be subject to many factors and variables; notwithstanding, what kind of information is being thought as necessary to evaluate or consider? All I'm asking is to be able to see the guidelines - and hopefully a way to collaborate.--[[User:Xavi|Xavi]] 17:04, 9 December 2006 (EST)

my question is how do u erase information on the journal
==Social Benefit==


hey guys nice work ...well i am making a project on u guys can u help me with the list of countries whu r a part of ur process
How will OLPC benefit countries when the majority of children do not attend public school or public school is not available?
thanks

Peace out


== Two activities ==
Mention was made in the NY Times article of a sponsorship program where people could fund a OLPC for a child in a target country. The quote was attributed to Nicholas N. How do we sign up?


hey i've got 2 questions
==Support for Self-Learners==
1. first of all why won't my eye chat open even if i have downloaded it
2. second how can i read e-books on my olpc
oh and one more question: can i contact the child who got the other laptop after i had paid for mine?
thanks
:Thanks for your questions. Sorry, I don't know what eye chat is. E-books in various formats can be read using the Read activity, and there are new E-book reader programs on http://activities.sugarlabs.org/ . No, you can't contact the child who got the other laptop. -- [[User:Quozl|Quozl]] 22:46, 26 July 2010 (UTC)


== How does the Log Viewer work? ==
I understand that you initially sell batches of at least 1 mio OLPC laptops to departments of education who distribute them to children going to public schools where trained teachers will put them to use applying localised curriculas. So far I can imagine quite well how OLPC hardware and software supports the kid's learning effort. This picture best matches developing countries such as OLPC's first subscribers rather than really poor 3rd world countries.


Dear Sir/Madam,
However, what about those children who cannot attend to schools and have no teachers, which is not uncommon in really poor 3rd world countries?
I still cannot imagine how illiterate kids (probably having illiterate parents) teach themselves the usage of the OLPC laptop and moreover teach themselves basic reading, writing and math.


As a part of an evaluation project we are trying to determine what activities are being used by the children, and for this reason we would like to know exactly how does the log viewer work. The journal presents the problem that activities may be erased by the children, therefore not providing a complete picture. So my questions are, what does the log viewer exactly show? Does it show all the activities used by the children? Does it only show errors in activities used by the children and if so what type of errors? Do you think the log-files can be used to determine what activities are the children using or the information won't be reliable towards that purpose?
:Personally (can't talk for others) I've been working under the assumption that some level of schooling will be available so that reading and writing, although not necessarily a given, will be a guided process. Nevertheless, I think that the [[Hardware specification#Specifications|sound processing]] capabilities of the OLPC would be more than enough to have [[Discussion of eBook feature set#Useful features might include|speech synthesis]] and [[End-user application software#Text to speech|text-to-speech]] allowing 'oral' tutoring and building [[Teaching Software#Language Skills|language skills]]. These technologies could also be used as an opportunity to include kids with [[Educational content ideas#Communication Aid|communication pathologies]] too.--[[User:Xavi|Xavi]] 23:43, 19 December 2006 (EST)


Also, is it possible to recover erased activities from the journal?
::I can imagine that your idea with the sound and text-to-speech functionalities could work provided that localised software supporting it comes with the laptop. Such software would have to be automatically loaded and run in such a way that when you boot it up, it starts to talk and explain by itself. By the way, similar software could support self-learning foreign languages e.g. for better access to the internet content. However, as far as I know text-to-speech is only available yet for very few (mainly first world) languages. Are there already plans or efforts in this direction?


Thank you for your help!
::I fear that as so often the poorest of the poor are left out because it is so much more difficult to help them having not the faintest bit of infrastructure. The OLPC project is a huge oportunity to them. OLPC has achieved already so much which seemed impossible that helping also the poorest finally appears feasible by supporting self-learning. This seems worth to be included in OLPC's project plans.


Federico
:::I'm not a project team-member so whatever I say is not official. That said, I can only add that the goal of the project is to '''provide/propose''' to governments a laptop that is (financially) cheap enough to be massively distributed to kids while being powerful enough to do all sorts of things. It'll be upto those governments to decide how they'll be deployed, what content will be included (and/or developed), etc. In some target [[countries]] schooling is so widespread making your scenario a marginal one (but nevertheless important). In other countries, I agree, things are quite the opposite. An interesting reading is the [[Learning Vision]] and its reference to the [http://pedia.media.mit.edu/wiki/Create_Project CREATE] project in Costa Rica, where some families moved into a town that had 1:1 computer education just so that their kids would have access to that kind of education. IOW, the population pro-actively flocked to that schooling system.
:::The 'poorest of the poor' will always be marginal to central efforts, a sad truth. There are millions of kids in sub-optimal schooling systems today, and I find it extremely important to raise that level and the OLPC addresses it squarely. Without the OLPC, millions of kids will be left in the broad swath of population that today we call the 'third world'.
:::One final thing to note, is that my idea for the "speaking-laptop that will teach a kid how to use it" is just that, an idea. The technical and pedagogical aspects of such a marvel... I can only guess...and dream. --[[User:Xavi|Xavi]] 12:23, 20 December 2006 (EST)


== how to repair olpc ==
::::I start to get the picture now. I was a bit confused about the mission statement given in the front page of http://laptop.org saying: '''"Introducing the children's laptop from One Laptop per Child — a potent learning tool created expressly for the world's poorest children living in its most remote environments."''' Probably I understood it too literally.
::::The OLPC laptop in the present form and with the presently available software seems useful mainly in areas where kids already have access to schools and teachers. This mainly covers developing countries rather than the even far poorer 3rd world countries which probably could not afford to buy OLPC laptops in large quantity anyway. Even if they received those laptops for free they could not make good use of it because they hardly have schools and teachers to tutor the majority of the childern in using them. Don't get me wrong. Each child getting a better education - no matter where - is a gain for all of us on this planet. The OLPC project is well under way to take this cause a great leap ahead. I was just confused thinking that the mission statement really meant "the world's poorest children" and I was trying to find out how this is intended to be achieved.


hi olpc i am call placide and my olpc can not switch on now but the screen can switch on but does not mark any thing
:::::If things go somewhere according to plan, the result will be millions of kids with a '''real''' chance at education where there was barely any (or parody of). And that for me, is not just 'good enough', it's 'not perfect but '''darn''' good'!
so it looks like has virus or it has corrupted so i would like to know how can i repair it and what can use to repair it
:::::BTW, "poorest" and "remotest" are terms that are hard to translate into a homogeneous reality. Who is poorer? A homeless in say, Miami, or one in Maputo? I consider Istambul a remote place, but I doubt somebody in Ankara would agree with me. Is distance the factor? Or the time it takes to get there? Or a relative/subjective mix? --[[User:Xavi|Xavi]] 09:01, 21 December 2006 (EST)
please i need help


:This can happen if you hold down the rotate button when you turn it on. Please try this: remove the battery, disconnect the cable, wait 10 seconds, put the battery back in, press the power button. The laptop should start. If it does not, then it may need repair. -- [[User:Quozl|Quozl]] 04:14, 25 October 2010 (UTC)
::::::My main questions are answered. I shortened both questions and answers a bit for the benefit of future readers. The emerging discussion might better be continued in a discussion section like the community portal of this wiki. --Roleic 20:25, 22 December 2006 (CET)


== Server Installation detail Guide ==
==Accessibility==


Hi,
What mechanism olpc is going to adopt to make it accessable for child with physical disabilities? Will there be seperate keyboards for blind with braile? Will there be alternate input methods for child with dysfunctioning hands?
I am am a new learner in this OLPC deployment team. I have installed a OLPC XS and had a problem with the eth0. During boot process it come to a stage where it says that IP determing information on eth0 fails. I have follwed the proper steps to install the server however it still gives me the same problem.
Can anyone out there assist me to get the eth0 working on my server.

== Skype microphone issue ==
--Ankur Sharma, [http://olpcnepal.org olpc Nepal] (ankur@olpcnepal.org)


I have been using Skype on my XO1 with ver. 656 without problems but after updating to ver. 802 and re-installing Skype using the directions given on http://wiki.laptop.org/go/Skype (Standard) the sound of the microphone is garbled, when placing a test call, even though it is clear when recording in terminal mode by using arecord and aplay. I have tried several settings in Alsamixer and Skype but without getting any change or improvement. Is there a patch or fix for this problem. Updating to ver. 852 did not work as Skype will not install on the 852 version on my XO1.
:As far as I know, OLPC keybords are standardized for each country's language/s, but not braille. The OLPC has [[Hardware specification#Specifications|3 USB ports]] to which external (braille) keyboards may be connected ([http://www.google.com/search?client=opera&rls=en&q=usb+braille+keyboard&sourceid=opera&ie=utf-8&oe=utf-8 quick search] and [http://www.portset.co.uk/braillekey1.htm sample result] or [http://www.hooleon.com/menu-stickers-braille.htm?gclid=CNWevcfho4kCFSiANAodGG3twA alternative method]). In order to better gauge the dimension of the issue, the [http://www.who.int/ World Health Organization] (WHO) has some statistics on the [http://www.who.int/mediacentre/factsheets/fs282/en/ incidence of blindness].
Note: I re-installed 802 and Skype several times and in several different executions following posts under OLPC but always with the same result. Placing a test call in Skype gives a playback with garbled microphone sounds like two voices overlapping each other and then shorting out.
:I have posted some observations about [[Input methods#Dasher - gesture text entry|Dasher]] as an alternative [[Input methods|input method]], not only for physical disabilities but general use too. --[[User:Xavi|Xavi]] 09:45, 21 December 2006 (EST)

== Problem updating from 656 and mouse freeze ==

Hello
I am having trouble updating from the 656 system and now my mouse and keyboard has frozen. Can you please advise me. Thank you. -- heather

:Hello Heather. What have you upgraded to? Does the mouse and keyboard remain frozen if you remove the power adapter and battery and put them back in? Write to {{help@laptop.org}} if you'd prefer e-mail. --[[User:Quozl|Quozl]] 02:01, 3 January 2011 (UTC)

::Hello
::I tried using the email but only got a generic response. To answer your questions:
::- I was trying to upgrade to the 10.1.2. I tried with the USB method and got the grey grid with a message underneath, something about NAND and size.
::- I then tried to update in terminal using all the various wordings proposed. That did not work either. I left the machine for a day or so and when I turned it back on the mouse and keyboard were frozen. When it lit up with the clock, it would go to a black screen with some text at about a quarter of the way round and then, before I could read it, it would go back to loading. I tried turning the machine on holding the O key which made the black text screen disappear but did not fix the freeze. I tried removing all power. I tried turning the machine on holding the rotate button. Nothing has worked yet. I'm really excited that you are responding to me and look forward to finding a solution.
::Take care. -- heather

:::Did the generic mail response give you a tracking number? If so, let me know what it was. That will help us mark it as being handled.

:::The grey grid sounds good, the message does not. There may be a fault in the laptop, or a problem with the download or preparation of the USB drive.

:::The grey grid occurs with an install of 10.1.2, so I'm presuming you are wanting to do an install, which wipes all data off the laptop. If so, please try again and this time check that you are following the install instructions below and tell me exactly what the message about the NAND says.

:::Regarding the update in terminal, I don't think you should try that again, because having started the install the contents of the internal storage is undefined, and the results may be unpredictable. The mouse and keyboard freeze is common; it happens if the laptop runs out of memory. We didn't test update from 656 and it may not work.

== Wi-Fi WAPs not visible in Neighborhood View ==

I installed the 10.1.3 version to my XO-1. Initially everything was fine including the WAP icons. Now I am only seeing the MESH target icons. I know the access points are working in several locations including m home one but still nothing but MESH is visible in the Neighbothood View. How can I fix this, short of trying a reinstall of 10.1.3?
:This will happen if automatic power management is enabled, which is the default, and the laptop is not kept awake for at least a minute. This is in the [http://wiki.laptop.org/go/Release_notes/10.1.3#XO-1_Automatic_power_management_issues release notes]. Try turning off automatic power management in the control panel. If that does not change things, please use Open Firmware to check the wireless card. Obtain the [[Ok]] prompt, and type ''scan-wifi'' then press return. This scans for wireless access points by turning on the radio receiver in the wireless card. Doing this test in Open Firmware is useful, because it excludes the 10.1.3 software entirely. If it doesn't show any access points, then there's no chance that 10.1.3 will. If it does show them, but 10.1.3 does not, then at least we know the problem is not hardware. Let us know how you go, because based on this test there are very different further tests to make. --[[User:Quozl|Quozl]] 23:20, 4 May 2011 (UTC)

== Super trouble with OLPC ==

hello friends! (first pardon me with the bad English...)

well, actually I'm repairing an XO-1 laptop OLPC, at the beginning it worked flawlessly, until i upgraded the bios firmware downloaded from: http://wiki.laptop.org/go/OLPC_Firmware_q2e45, after the process, it won't boot anymore. the trouble is i can't figure out how to make it boot... i installed this build: http://wiki.laptop.org/go/Release_notes/11.2.0 no luck... always end in the OK command prompt... same thing happened to every build version I've tried, downloaded and installed from here: http://wiki.laptop.org/go/Release_notes also, I've tried to re flash the bios and no luck, i use several ROM files, from the Q2E41(the original ROM bios that comes in my OLPC) to the last Q2E45, and still no luck... I've tried to install SO images with several SD cards with 1, 2, and 4 GB of storage capability, all of them formatted in several ways: FAT, exFAT, vFAT, FAT12, FAT16, and FAT32... and nope...the OLPC won't boot... then I've tried luck with 2 kingston USB memory sticks, one is a 1GB and the other is a 8GB storage capability, tried with FAT, exFAT, vFAT, FAT12, FAT16, and FAT32 formats, it install the OS image in the OLPC, but still the laptop won't boot... Tired of this, i get a developer key from here: http://wiki.laptop.org/go/Activation_and_developer_keys, and tried it without any luck at all...

NOTE # 1: the OLPC hardware test report that everything is good...

NOTE # 2: all builds and bios I've downloaded and used to restoring my OLPC were for the XO-1 laptop model.

NOTE # 3: all clean-install and bios writing processes ended correctly with no failures.

NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.

NOTE # 5: all the internal memory chips are in good shape, also I've made this process: http://wiki.laptop.org/go/XO_Flash_Bad_Blocks, and the flash nand only got around 15 bad blocks... then i made this process: http://wiki.laptop.org/go/Fix_Clock and nothing, the OLPC always ends in the OK prompt, and never run the installed OS image...

anyone can light any clues about what is wrong with this OLPC???

any responses here or in my e-mail dj.electron@gmail.com with help to solve this mystery, are welcome .

Regards!!!

hola como estan

mi nombre es kevin molinares, soy de colombia y tengo un problema con una olpc xo-1.
Resulta que soy tecnico en reparacion de computadores, entonces me dieron una olpc xo-1 para formatear windows,
porque el sistema que traia le cayo muchos virus y estava muy lento, entonces yo formatee la SD de 4GB que trae pero
no he podido hacer la instalacion de windows he intentado copiar una instalacion limpia que hice desde una maquina virtual pero no sirve
la unica forma que logre iniciar es con un hirent boot CD.
ahora si la pregunta ...

como hago o si necesito un driver, o donde bajo el windows xp para esta olpc xo-1 .. ya venia con windows xp de fabrica es mas tiene la licencia de windows original pegada debajo de la bateria, que tengo que hacer ?.

I want to download stuff on my XO laptop, but it keeps taking me to archive manager, which I don't like. I need instructions now!!!
:that is probably because you are downloading files that can only be opened by archive manager. exactly what files are you downloading? perhaps the files are not designed for your XO laptop. --[[User:Quozl|Quozl]] 22:34, 11 October 2012 (UTC)

== Technological and estructural diagram of the OLPC project ==

I am a volunteer at an organization that implements the OLPC project in Honduras. I am trying to help in different areas and one of them is to create documentation that will guide the end users of the program. This documentation is aided with descriptive images and one of them, which I need from you is the one that has the diagram of the structure of the OLPC project (technology oriented). I was looking at some links that show this diagram but I can not find it anymore. It has an oval of the acronym OLPC in the center and it branches out to the left with technology and to the right with outreach and education. It will be of great help if you can provide me with such an image.

Thank you,

== Alvin, mesh ==

I have a couple of XO's with me. I would like to change the network protocols and analyze the results.

I would like to know where is the mesh protocol located on the XO? From where can I change the protocols?

Thanks in advance.
:Hello. The mesh protocol is only available on the XO-1 model. Confirm you have an OLPC XO-1 model first. The OLPC XO-1.5, XO-1.75 and XO-4 models do not have mesh. Next, the mesh is implemented inside the wireless module firmware, with some small functions in the Linux kernel. Because it is in the firmware, you cannot practically change the protocol. --[[User:Quozl|Quozl]] 03:44, 8 April 2013 (UTC)

::Hello Again thanks for a quick response earlier. Yes I have XO-1. I have some more Questions. Is there any way I can change the protocols in XO-1. Will I be able to change the Network Protocol Parameters? If Yes than how? Thanks in advance.

:::It depends on which protocol you wish to change. No, the mesh physical protocol cannot be changed. Yes, all the other network protocols above the physical layer can be changed, using Linux commands, Linux kernel run-time configuration parameters, and Linux kernel build-time configuration parameters. Which specific protocol and parameter do you wish to change, and why? --[[User:Quozl|Quozl]] 01:00, 9 April 2013 (UTC)

::::Thanks for the information earlier. My interest is in the routing. I am doing a research on the mesh protocols. Some more questions to answer please. (1) Is the routing (and the corresponding layer) is part of the firmware too? (2) Which application layer software (GUI..etc) do they include to enable students to create links and task on the mesh? Thanks in advance.

:::::It is of historic use, I guess. XO-1 mesh implementation was not continued beyond XO-1. Our XO-1.5, XO-1.75, and XO-4 models use ad-hoc rather than mesh. To answer your questions: (1) Routing on the mesh is entirely handled by the wireless module firmware. It is an implementation of IEEE 802.11s draft. It is incompatible with IEEE 802.11s final. (2) Sequence is: user selects Sugar network view, then clicks on a Mesh icon. Sugar sends mesh request command to Network Manager daemon. Network manager sends command to kernel. Kernel sends command to wireless module via USB. Reply cascades back up the stack, and the Mesh icon is changed to show it is selected. User starts a Sugar activity and enables sharing. Activity uses multicast UDP to advise activity is available for sharing. Other nodes on the mesh receive the UDP and update their network view. --[[User:Quozl|Quozl]] 03:39, 9 April 2013 (UTC).

::::::Thanks for the information earlier. Will I be able to get a chance to edit wireless module firmware? thanks

:::::::Chance: 0.1% Because it is in the firmware, you cannot practically change the mesh protocol. The firmware is the property of Marvell. The source code is not public. The firmware is in the file usb8388.bin which is stored on the laptop. The file is sent to the wireless module after power is turned on. There is no public documentation for the ARM and baseband processor on the module, and these chips are from a silicon design around 2005, and probably no longer available. The module is soldered to the main board. --[[User:Quozl|Quozl]] 04:58, 9 April 2013 (UTC)

::::::::Hello, I have some more questions. The network is usually organised in a few layers, traditionally in seven. The lowest layer is the physical layer. That is indeed firmware and cannot be edited. Above that we have the data link, network, and transport layer. Routing will happen in one of these layers, usually in the network, sometimes in the data link layer. Question is: where is the routing taking place for the OLPC XO-1 and the other versions of OLPC XO (like XO-1.5 ..etc). thanks.

:::::::::We use TCP/IP for networking on OLPC XO, and TCP/IP is not based on a seven layer model. Wikipedia has an [http://en.wikipedia.org/wiki/Internet_protocol_suite#OSI_and_TCP.2FIP_layering_differences article that describes OSI and TCP/IP layering differences]. Routing happens in as many layers as are required by the definition of those layers, not only one. There are two layers that contain routing for XO-1, and one for XO-1.5, XO-1.75, and XO-4. The mesh on XO-1 automatically maintains a list of mesh nodes in the wireless module, considered to be physical routing. The other layer is TCP/IP routing, which is provided by Linux, and is not unique to OLPC XO, so it would be redundant to describe it here. Look for a text that describes TCP/IP. --[[User:Quozl|Quozl]] 01:32, 10 April 2013 (UTC)

::::::::::Hello. I would like to know, is there anyway where the protocol parameters and be changed and analyzed? Thanks.

:::::::::::Your question is ambiguous. If you mean the mesh routing, then [http://dev.laptop.org/pub/firmware/libertas/RELEASE_NOTES] may help you. If you mean Linux routing, then consult a text on TCP/IP and Linux. --[[User:Quozl|Quozl]] 23:13, 10 April 2013 (UTC)

::::::::::::Hello, sorry. I would like to know if mesh routing protocol parameters on OLPC laptops can be altered (modified/changed) and analyzed? thanks
:::::::::::::See [[Wireless_Driver_README]], [http://dev.laptop.org/pub/firmware/libertas/RELEASE_NOTES RELEASE_NOTES] and [[Mesh_Forwarding_Table]]. Please also consider [[Mailing_lists]] ... the Devel mailing list is a more suitable place for this discussion, and you would find a larger audience. --[[User:Quozl|Quozl]] 00:28, 11 April 2013 (UTC)

New questions

My OLPC stucked off after starting up and please also guide me that from where i can get new charger for my olpc?

Question

We are planning to help OPLC but we need to check the Financial Statements of the organization. Does somebody know where can we get this information?

From OLPC directly, or the government or other regulators. I don't think you should rely on what contributors to a community Wiki might tell you ... that's not a rigorous method. --Quozl 03:23, 13 February 2012 (UTC)

Question

I turned on my OLPC but it didn't show anything.What do I do?

Check out Keyboard freeze fix for os 650-656 it might be your problem. Hard to say, unless you can give some more information, like when you last used the XO, whether the power indicator turns on, whether the display backlight turns on. --Quozl 21:04, 30 August 2011 (UTC)

Question

how do download windows xp on to my olpc xo and how do you access your downloads

There is no way to get Windows XP for your individual OLPC. Microsoft does not make it available to individuals, and OLPC has nothing to do with that.

Downloads

How to access your downloads?

If you download things on the OLPC, they should show up in the Journal, which is one of the Activities that's always running. It looks like a little spiral notebook. You can also open the journal by pressing the "magnifying glass" icon in the upper-left hand part of the keyboard.

how do you start your downloads

I downloaded adobe flash player but i still can't watch my videos i know you go to journal and the file and click start but it doesn't work.

See Adobe Flash for details. Mariano 06:44, 8 December 2009 (UTC)

your disk is full

What should i do if i go to my record activity and it says my disk is full?

You should open your Journal and remove large files or activities. Mariano 06:44, 8 December 2009 (UTC)

== It seems that with the new built (8.2) in the XO the existing Scratch files are difficult to copy into a USB. I can't use the function "save as" or even copy them from the terminal. Any idea what to do? il me semble que mon "xo" est bloqué peut etre plein. que faire?

Mamadou Niang 00221776467585 Sénégal

How do I chat with other people in the world?

My xo is hooked up to the internet but I still don't know how to chat with other people in the world could you tell me how please?

First connect to a Jabber server or your local school network. Then you can see other people on your network and will be able to chat with them.
You can also download XoIRC and chat with people using that activity. 02:34, 17 December 2009 (UTC)

Downloads

How do I download music on my labtop?

Click on a file to download. Then open it from your Journal. Alternately, install an activity like Jukebox.

How do I download Doom?

The page about it is titled Doom. 02:34, 17 December 2009 (UTC)

Two activities

hey i've got 2 questions 1. first of all why won't my eye chat open even if i have downloaded it 2. second how can i read e-books on my olpc oh and one more question: can i contact the child who got the other laptop after i had paid for mine? thanks

Thanks for your questions. Sorry, I don't know what eye chat is. E-books in various formats can be read using the Read activity, and there are new E-book reader programs on http://activities.sugarlabs.org/ . No, you can't contact the child who got the other laptop. -- Quozl 22:46, 26 July 2010 (UTC)

How does the Log Viewer work?

Dear Sir/Madam,

As a part of an evaluation project we are trying to determine what activities are being used by the children, and for this reason we would like to know exactly how does the log viewer work. The journal presents the problem that activities may be erased by the children, therefore not providing a complete picture. So my questions are, what does the log viewer exactly show? Does it show all the activities used by the children? Does it only show errors in activities used by the children and if so what type of errors? Do you think the log-files can be used to determine what activities are the children using or the information won't be reliable towards that purpose?

Also, is it possible to recover erased activities from the journal?

Thank you for your help!

how to repair olpc

hi olpc i am call placide and my olpc can not switch on now but the screen can switch on but does not mark any thing so it looks like has virus or it has corrupted so i would like to know how can i repair it and what can use to repair it please i need help

This can happen if you hold down the rotate button when you turn it on. Please try this: remove the battery, disconnect the cable, wait 10 seconds, put the battery back in, press the power button. The laptop should start. If it does not, then it may need repair. -- Quozl 04:14, 25 October 2010 (UTC)

Skype microphone issue

I have been using Skype on my XO1 with ver. 656 without problems but after updating to ver. 802 and re-installing Skype using the directions given on http://wiki.laptop.org/go/Skype (Standard) the sound of the microphone is garbled, when placing a test call, even though it is clear when recording in terminal mode by using arecord and aplay. I have tried several settings in Alsamixer and Skype but without getting any change or improvement. Is there a patch or fix for this problem. Updating to ver. 852 did not work as Skype will not install on the 852 version on my XO1. Note: I re-installed 802 and Skype several times and in several different executions following posts under OLPC but always with the same result. Placing a test call in Skype gives a playback with garbled microphone sounds like two voices overlapping each other and then shorting out.

seria muy ueno si tendria para algunos alumnos mas avanzados la posibilidad de una de las nuevas plaquetas minis como para subir a 8 gb el disco solido , pero me parece que la memoria de 1 gb ya viene incorporada en el mother . y no tiene ningun slot

hoy dia los costos bajando y ojala en tiempos proximos alcancen un precio infimo como para poder incorporar mas almacenamiento.

Problem updating from 656 and mouse freeze

Hello I am having trouble updating from the 656 system and now my mouse and keyboard has frozen. Can you please advise me. Thank you. -- heather

Hello Heather. What have you upgraded to? Does the mouse and keyboard remain frozen if you remove the power adapter and battery and put them back in? Write to help@laptop.org (our OLPC technical staff) if you'd prefer e-mail. --Quozl 02:01, 3 January 2011 (UTC)
Hello
I tried using the email but only got a generic response. To answer your questions:
- I was trying to upgrade to the 10.1.2. I tried with the USB method and got the grey grid with a message underneath, something about NAND and size.
- I then tried to update in terminal using all the various wordings proposed. That did not work either. I left the machine for a day or so and when I turned it back on the mouse and keyboard were frozen. When it lit up with the clock, it would go to a black screen with some text at about a quarter of the way round and then, before I could read it, it would go back to loading. I tried turning the machine on holding the O key which made the black text screen disappear but did not fix the freeze. I tried removing all power. I tried turning the machine on holding the rotate button. Nothing has worked yet. I'm really excited that you are responding to me and look forward to finding a solution.
Take care. -- heather
Did the generic mail response give you a tracking number? If so, let me know what it was. That will help us mark it as being handled.
The grey grid sounds good, the message does not. There may be a fault in the laptop, or a problem with the download or preparation of the USB drive.
The grey grid occurs with an install of 10.1.2, so I'm presuming you are wanting to do an install, which wipes all data off the laptop. If so, please try again and this time check that you are following the install instructions below and tell me exactly what the message about the NAND says.
Regarding the update in terminal, I don't think you should try that again, because having started the install the contents of the internal storage is undefined, and the results may be unpredictable. The mouse and keyboard freeze is common; it happens if the laptop runs out of memory. We didn't test update from 656 and it may not work.
Feel free to send me an e-mail at quozl@laptop.org if you like. --Quozl 22:24, 4 January 2011 (UTC)


How to install signed build os852 of release 10.1.2 on XO-1.

The build is installed to the internal NAND flash device. You will need a USB drive of at least 1 GB capacity, but only for the duration of the installation.

ALL USER DATA WILL BE ERASED FROM THE LAPTOP!

  • Prepare the USB drive:
    • Download os852.img,
    • Save the file to the top directory of the USB drive,
    • Download os852.img.fs.zip,
    • Save the file to the top directory of the same USB drive,
    • Rename the file to fs.zip, (removing the os852.img part of the name),
    • Check the USB drive contains at least the two files fs.zip and os852.img.
  • Prepare the laptop:
    • Make a copy of any data you wish to keep,
    • Check the battery is inserted and locked,
    • Check that the power cord is in place and the battery indicator is green,
    • Turn off the laptop, unless it is already off,
    • Insert the USB drive into any USB port on the laptop,
  • Start installing:
    • Hold down all four game keys (see this in pictures),
    • Turn on the laptop,
    • Wait for the message Release the game keys to continue,
    • Release the game keys.

Installation progress will be displayed. Green colour will fill yellow blocks. It will take about five minutes. Once finished, the laptop will reboot automatically. Remove the USB drive during or after the reboot. The USB drive can be used on other laptops.

If you see a message Boot failed then either:

  • the USB drive has not been properly prepared, or;
  • the firmware is out of date and should be updated (see Firmware).

Activities disappear

What to do if all of my activities disappear? Please Help!!!

Reinstall might be a last resort. Someone else asked this recently, and it turned out that changing the language to one that isn't supported may cause this. Change it back. --Quozl 23:38, 1 February 2011 (UTC)

Wi-Fi WAPs not visible in Neighborhood View

I installed the 10.1.3 version to my XO-1. Initially everything was fine including the WAP icons. Now I am only seeing the MESH target icons. I know the access points are working in several locations including m home one but still nothing but MESH is visible in the Neighbothood View. How can I fix this, short of trying a reinstall of 10.1.3?

This will happen if automatic power management is enabled, which is the default, and the laptop is not kept awake for at least a minute. This is in the release notes. Try turning off automatic power management in the control panel. If that does not change things, please use Open Firmware to check the wireless card. Obtain the Ok prompt, and type scan-wifi then press return. This scans for wireless access points by turning on the radio receiver in the wireless card. Doing this test in Open Firmware is useful, because it excludes the 10.1.3 software entirely. If it doesn't show any access points, then there's no chance that 10.1.3 will. If it does show them, but 10.1.3 does not, then at least we know the problem is not hardware. Let us know how you go, because based on this test there are very different further tests to make. --Quozl 23:20, 4 May 2011 (UTC)

Super trouble with OLPC

hello friends! (first pardon me with the bad English...)

well, actually I'm repairing an XO-1 laptop OLPC, at the beginning it worked flawlessly, until i upgraded the bios firmware downloaded from: http://wiki.laptop.org/go/OLPC_Firmware_q2e45, after the process, it won't boot anymore. the trouble is i can't figure out how to make it boot... i installed this build: http://wiki.laptop.org/go/Release_notes/11.2.0 no luck... always end in the OK command prompt... same thing happened to every build version I've tried, downloaded and installed from here: http://wiki.laptop.org/go/Release_notes also, I've tried to re flash the bios and no luck, i use several ROM files, from the Q2E41(the original ROM bios that comes in my OLPC) to the last Q2E45, and still no luck... I've tried to install SO images with several SD cards with 1, 2, and 4 GB of storage capability, all of them formatted in several ways: FAT, exFAT, vFAT, FAT12, FAT16, and FAT32... and nope...the OLPC won't boot... then I've tried luck with 2 kingston USB memory sticks, one is a 1GB and the other is a 8GB storage capability, tried with FAT, exFAT, vFAT, FAT12, FAT16, and FAT32 formats, it install the OS image in the OLPC, but still the laptop won't boot... Tired of this, i get a developer key from here: http://wiki.laptop.org/go/Activation_and_developer_keys, and tried it without any luck at all...

NOTE # 1: the OLPC hardware test report that everything is good...

NOTE # 2: all builds and bios I've downloaded and used to restoring my OLPC were for the XO-1 laptop model.

NOTE # 3: all clean-install and bios writing processes ended correctly with no failures.

NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.

NOTE # 5: all the internal memory chips are in good shape, also I've made this process: http://wiki.laptop.org/go/XO_Flash_Bad_Blocks, and the flash nand only got around 15 bad blocks... then i made this process: http://wiki.laptop.org/go/Fix_Clock and nothing, the OLPC always ends in the OK prompt, and never run the installed OS image...

anyone can light any clues about what is wrong with this OLPC???

any responses here or in my e-mail dj.electron@gmail.com with help to solve this mystery, are welcome .

una pequeña ayuda con una olpc

hola como estan

mi nombre es kevin molinares, soy de colombia y tengo un problema con una olpc xo-1. Resulta que soy tecnico en reparacion de computadores, entonces me dieron una olpc xo-1 para formatear windows, porque el sistema que traia le cayo muchos virus y estava muy lento, entonces yo formatee la SD de 4GB que trae pero no he podido hacer la instalacion de windows he intentado copiar una instalacion limpia que hice desde una maquina virtual pero no sirve la unica forma que logre iniciar es con un hirent boot CD. ahora si la pregunta ...

como hago o si necesito un driver, o donde bajo el windows xp para esta olpc xo-1 .. ya venia con windows xp de fabrica es mas tiene la licencia de windows original pegada debajo de la bateria, que tengo que hacer ?. le agradezco su respuesta que tengan un buen dia

Skype Video Calls & Broadband

I have 1.16 gb left of my broadband allowance this month. How long can I chat on skype using the video call facility?

turn on

my laptop turn on but then the screen stays black i have charged to full battery but it still does not do anything

downloading stuff

I want to download stuff on my XO laptop, but it keeps taking me to archive manager, which I don't like. I need instructions now!!!

that is probably because you are downloading files that can only be opened by archive manager. exactly what files are you downloading? perhaps the files are not designed for your XO laptop. --Quozl 22:34, 11 October 2012 (UTC)

Technological and estructural diagram of the OLPC project

I am a volunteer at an organization that implements the OLPC project in Honduras. I am trying to help in different areas and one of them is to create documentation that will guide the end users of the program. This documentation is aided with descriptive images and one of them, which I need from you is the one that has the diagram of the structure of the OLPC project (technology oriented). I was looking at some links that show this diagram but I can not find it anymore. It has an oval of the acronym OLPC in the center and it branches out to the left with technology and to the right with outreach and education. It will be of great help if you can provide me with such an image.

Thank you,

Alvin, mesh

I have a couple of XO's with me. I would like to change the network protocols and analyze the results.

I would like to know where is the mesh protocol located on the XO? From where can I change the protocols?

Thanks in advance.

Hello. The mesh protocol is only available on the XO-1 model. Confirm you have an OLPC XO-1 model first. The OLPC XO-1.5, XO-1.75 and XO-4 models do not have mesh. Next, the mesh is implemented inside the wireless module firmware, with some small functions in the Linux kernel. Because it is in the firmware, you cannot practically change the protocol. --Quozl 03:44, 8 April 2013 (UTC)
Hello Again thanks for a quick response earlier. Yes I have XO-1. I have some more Questions. Is there any way I can change the protocols in XO-1. Will I be able to change the Network Protocol Parameters? If Yes than how? Thanks in advance.
It depends on which protocol you wish to change. No, the mesh physical protocol cannot be changed. Yes, all the other network protocols above the physical layer can be changed, using Linux commands, Linux kernel run-time configuration parameters, and Linux kernel build-time configuration parameters. Which specific protocol and parameter do you wish to change, and why? --Quozl 01:00, 9 April 2013 (UTC)
Thanks for the information earlier. My interest is in the routing. I am doing a research on the mesh protocols. Some more questions to answer please. (1) Is the routing (and the corresponding layer) is part of the firmware too? (2) Which application layer software (GUI..etc) do they include to enable students to create links and task on the mesh? Thanks in advance.
It is of historic use, I guess. XO-1 mesh implementation was not continued beyond XO-1. Our XO-1.5, XO-1.75, and XO-4 models use ad-hoc rather than mesh. To answer your questions: (1) Routing on the mesh is entirely handled by the wireless module firmware. It is an implementation of IEEE 802.11s draft. It is incompatible with IEEE 802.11s final. (2) Sequence is: user selects Sugar network view, then clicks on a Mesh icon. Sugar sends mesh request command to Network Manager daemon. Network manager sends command to kernel. Kernel sends command to wireless module via USB. Reply cascades back up the stack, and the Mesh icon is changed to show it is selected. User starts a Sugar activity and enables sharing. Activity uses multicast UDP to advise activity is available for sharing. Other nodes on the mesh receive the UDP and update their network view. --Quozl 03:39, 9 April 2013 (UTC).
Thanks for the information earlier. Will I be able to get a chance to edit wireless module firmware? thanks
Chance: 0.1% Because it is in the firmware, you cannot practically change the mesh protocol. The firmware is the property of Marvell. The source code is not public. The firmware is in the file usb8388.bin which is stored on the laptop. The file is sent to the wireless module after power is turned on. There is no public documentation for the ARM and baseband processor on the module, and these chips are from a silicon design around 2005, and probably no longer available. The module is soldered to the main board. --Quozl 04:58, 9 April 2013 (UTC)
Hello, I have some more questions. The network is usually organised in a few layers, traditionally in seven. The lowest layer is the physical layer. That is indeed firmware and cannot be edited. Above that we have the data link, network, and transport layer. Routing will happen in one of these layers, usually in the network, sometimes in the data link layer. Question is: where is the routing taking place for the OLPC XO-1 and the other versions of OLPC XO (like XO-1.5 ..etc). thanks.
We use TCP/IP for networking on OLPC XO, and TCP/IP is not based on a seven layer model. Wikipedia has an article that describes OSI and TCP/IP layering differences. Routing happens in as many layers as are required by the definition of those layers, not only one. There are two layers that contain routing for XO-1, and one for XO-1.5, XO-1.75, and XO-4. The mesh on XO-1 automatically maintains a list of mesh nodes in the wireless module, considered to be physical routing. The other layer is TCP/IP routing, which is provided by Linux, and is not unique to OLPC XO, so it would be redundant to describe it here. Look for a text that describes TCP/IP. --Quozl 01:32, 10 April 2013 (UTC)
Hello. I would like to know, is there anyway where the protocol parameters and be changed and analyzed? Thanks.
Your question is ambiguous. If you mean the mesh routing, then [1] may help you. If you mean Linux routing, then consult a text on TCP/IP and Linux. --Quozl 23:13, 10 April 2013 (UTC)
Hello, sorry. I would like to know if mesh routing protocol parameters on OLPC laptops can be altered (modified/changed) and analyzed? thanks
See Wireless_Driver_README, RELEASE_NOTES and Mesh_Forwarding_Table. Please also consider Mailing_lists ... the Devel mailing list is a more suitable place for this discussion, and you would find a larger audience. --Quozl 00:28, 11 April 2013 (UTC)

Who has heard this OLPC "nerdcore" rap song?

The nerdcore rappers called "Dual Core" published a song about the OLPC on Jun 17, 2013. Find it on YouTube here. With only 3,930 views recorded as I write this on June 21, 2017, it would appear that a great many more people might want to give it a listen. Maybe you? - Docdtv 08:28, 21 June 2017 (UTC)

Fascinating, thanks. Don't think anybody else apart from me is reading this Wiki though. If you'd like to get it out there, try other methods. --Quozl 11:01, 21 June 2017 (UTC)
