==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)
Thanks, Wikipedia user: Betbuster [[User:134.2.57.213|134.2.57.213]] 09:20, 19 December 2006 (EST)


== 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?

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?
What about usability testing for children? A recent article quoted the OLPC chairman as saying: "Granted, I'm not a child. I don't know if it's going to be intuitive to children." Was there research?
: Click on a file to download. Then open it from your [[Journal]]. Alternately, install an activity like [[Jukebox]].

==Deployment Criteria & Metrics==
: The page about it is titled [[Doom]]. 02:34, 17 December 2009 (UTC)


== Reset settings ==
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.


I need to knnow how to reset the name on my xo laptop
: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.

== Viruses ==
::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.


How Do I erase viruses from my xo
: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.

::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)


== reset journal info ==
==Timor Leste (East Timor) not involved yet and how to get the process off on the right foot==


my question is how do u erase information on the journal
I am a volunteer IT worker here in Dili. I wish to follow through on getting the Government/Min of Education involved.
Is there a set of templates/docs/procedures for me to follow? If so, then I think that they would be very useful for other countries.
thanks chris

Peace out


== Two activities ==
Thanks for writing in.
Right now I think the whole world knows about the program. You may contact your countries Minster of Education and try to start a dialogue about the service OLPC is offering. If they are interested you may then try with in your country to find big donor corporations that will come up with the funds for your country and you can also contact me on this site to ask more questions in how you can do that. I am sure you speak the native language which would make this much easier that you can also speak English too. This way I can explain this to you as in how to do that.
Thanks

hey i've got 2 questions
==Social Benefit==
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? ==
How will OLPC benefit countries when the majority of children do not attend public school or public school is not available?


Dear Sir/Madam,
:Your statistics are questionable. What is your source for such an outrageous statement? In any case, the OLPC is not distributing laptops to schools, they are distributing laptops to kids. In thousands of small towns and villages, the existence of a mesh of laptops will create a learning infrastructure that can function without a school building.


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?
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?


Also, is it possible to recover erased activities from the journal?
:If there was such a quote, it was incorrect. The laptops are being purchased by national ministries of education. If you want to sponsor the purchase of laptops then you must make arrangements with a national ministry of education. --[[User:Hunter|Hunter]] 10:12, 8 January 2007 (EST) OLPC4USA is not connected to Hunter or the Hands of Love Program.


Thank you for your help!
The OLPC will not be involved at all in such arrangements. In the USA you should contact [[OLPC4USA]]. For personal purchase you should read the [[Retail]] page.

== how to repair olpc ==
==Support for Self-Learners==


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
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.
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. -- [[User:Quozl|Quozl]] 04:14, 25 October 2010 (UTC)
: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.

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?

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

: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]).

== Programming ==

Does the os suport basic programming.
:Short answer: yes.
:A bit longer, assuming that by 'basic programming' you mean 'simple programming' (instead of the BASIC language), you have [[Etoys]] ([[Squeak]]), [[LOGO]], [[Javascript]], [[Csound]], and most other things are in [[Python]]. You should also check the pages on [[software]] and [[our software]]. And since the project is based on an [[OLPC on open source software|open-source]] philosophy, even the OS will be accessible to kids to fiddle with.--[[User:Xavi|Xavi]] 16:49, 27 December 2006 (EST)

== I question whether there is some benefit for us or you by getting involved ==

We are a St. Louis MO based charity doing Health Related activity in many poor parts of the world including Ecuador, Africa, Asia etc. We have recently been asked by Ecuador officials to assist in several different activates, including build schools, clinics, furnish computers etc.(we have a current request for 100 computers that we are trying to fulfill.

Or name is Wings of Hope and you can view our website at www.wings-of-hope.org to get some idea of what we do and who we do it for, both locally and around the world. We are a volunteer organization with pilots, nurses and support people stationed in many countries in poverty stricken areas. We are non political, non religious based, have no ethnic motivations nor any other motivation based issues except to help people in need.

We furnish air transport service to poor people in the central part of the United States to get them to health care facilities. We set up health clinics in poor areas of the US and we Donate aircraft to many areas of the world to be used as Air Ambulances. The website above will reveal a lot about Wings of Hope activates.

I saw the article in Popular Science about your computers and I just feel there is something that we can offer that will advance your cause. Our relationships appear to be with the kind of folks you are trying to reach. If you feel we can be of any assistance to your efforts, we would like to discuss the issue(s).

From what has been publicly displayed this is mainly a government program that has to have approval from the hosting country to be implemented. Depending on the type of services you are offering this may or may not be a a program that could fit in to your NGO's aim.
But if you are intrested from the stand point of ONE LAP TOP FOR EVERY CHILD then you should keep in touch and ask more questions as they come to you.
Thanks

== Availability ==

You could make this wonderful PC available to everyone on a commercial basis. Charge USD 150 or 200 for it (I would at least buy one) and let the profit sponsor kids in the 3rd world. This would also up the produced volume getting the hw costs even lower.

:You should read the [[Retail]] page where this is covered. Any changes to the situation will be updated on that page.



== What about poor kids in our country (USA)? ==

As a technology professional, I see tremendous value in OLPC. I see OLPC changing the way we educate our children. I understand that school children in the USA have more opportunities than school children in most parts of the world. However, we do have school children in this country that '''need''' the help that OLPC can provide.

Why are children in the USA not even on the deployment radar?

:OLPC does not '''deploy''' laptops. That job is done by national ministries of education. In the USA, this would be the Secretary of Education. You should direct your concerns to the Secretary or join with [[OLPC4USA]] to make this happen.

== security ==

i just learned of this project today and am very excited about it. one of the things that holds poor children back is lack of experience. children have so many marvelous ideas in their heads, but if a child doesn't know that architects or engineers exist, he or she can't hope to become one. not that becoming one is the point. the point is having a future to hope for as well as something to enjoy in the present. the children will develop these computers in ways none of us can imagine. some will create great works of art. some will become business moguls. some will find ways to help others. what a wonderful thing.
i can also see how this project might become another economic project for the whole village. like the entrepreneur who buys a cell phone and sells minutes of its use, somebody's going to buy a hard drive and a USB cable. or do something else i can't imagine. i hope mohammed yunas knows about this.
which brings me to my concern. as described on these pages, these machines are incredibly useful. i want one myself. i can wait until the idea makes it to the open market, but many adults are not so patient. i can see these powerful machines and their mesh network ability being very attractive to bandits, drug dealers, the parents of the children who can use them in their businesses and so on. it's not just that the children would lose their laptops. i am concerned for their safety, and that this will become another tool to enslave child for the benefit of adults. (i'm not talking about the child keeping the books for a family business, which helps the whole family.) i have no doubt that the minds who designed these incredible machines can solve this dilemma as well. i think you have probably already thought about this, but i didn't find where the site addressed it. i felt it would be wrong not to bring it up to be sure the children are protected.
thank you for doing this for the world's children. i look forward to learning more and finding ways to contribute.

(just want the "creators" to know the following comment regarding energy is not from dee.)

Regarding the energy source for the machine - I would love to imagine children walking or running to school or home with their machines swinging along. Since The Crank is out, how about self-winding, through movement? I have a 40-year old watch that does it. Have you thought about using self-winding as some part of the power question? Creators, commence!

== Contribution towards Programming ==

Hello,

I am really interested in contributing towards the programming efforts in linux kernel and python. Please let me know how shall I proceed and start contributing towards it?

== Volunteering ==

How does a computer science professional contact OPLC about volunteering their time to help deploy the laptops and train new users? Is there an affliation with GeekCorps?

== XO for Propaganda? ==

Dear OLPC,

I believe wholly in the OLPC program and am very happy to learn that units are shipping. I do, however, have one concern:

Is it possible for education ministries, who will be distributing the XO laptop, to map political propaganda onto the XO prior to release? Imagine if a particular political party in power had used their party's political messaging in the splash screen at XO startup. That messaging would be carried with a child for a very long time.

On the flip side, if a particular country has a problem that needs tackling, such as AIDS, then it would be beneficial if there were messaging intended to tackle that problem embedded as a default [but end-user changeable] setting.

I assert that OLPC needs to take top-down initiative to ensure that governments do not abuse this new mode of communication.

== What about American Senior Citizens? ==

Why are American Senior Citizens being excluded from this very worthwhile project? As a computer-literate senior citizen I have found that most wives (mine included) in the senior age category will be computer-helpless when they become widowed. Please, puhleeeeze consider opening the OLPC program to American seniors who have been left behind in the current computer obsessed world. Thanx, M. Zipes, Poughkeepsie, NY <font size="1">(Moved question originally posted by [http://wiki.laptop.org/index.php?title=Special:Contributions&target=69.121.101.152 69.121.101.152] in [[Image talk:Contentatlaptop.png]].</font>

:Uh? Not only this question was out of place, but also, dare say, conceptually. OLPC = One Laptop Per CHILD. In the best of worlds, it would be One Laptop Per CITIZEN&mdash;regardless of nationality, age, etc. but it's not the case. Children are the priority, and in developing countries.
:A more congenial answer would be to point you to [[OLPC4USA]] and ask you to lobby your government with them.--[[User:Xavi|Xavi]] 09:59, 2 January 2007 (EST)

there are classes available almost anywhere in the US for any adult, and specifically seniors, to take. in addition, US seniors, as a group, are the wealthiest people on the planet. your wife has a computer in the house and does not learn. puhleeeeze think of others who do not have the resources and try to help them. dee pearson

== Theft of laptops from children ==


Perhaps it would be possible to use facial/voice recognition software and the laptop camera/microphone to ensure that the laptop will only work if one child (selected by an administrator using a complex password) is using it. (This would avoid situations where the child might give up a password under duress)?

== Nicholas Negroponte ==

Hello - how can I get involved and help Nicholas with his $100 laptop project? I am an accountant by trade and am looking to get involved in the voluntary sectory. I should be grateful if you would pass this message on to him. Many thanks - ankit.dodhia@hotmail.com

Wish there was a version of fedora with the Sugar os, so they could be put on existing low end laptops and desktops. That would be great for schools that have older hardware, so they do not have to purchase newer machines. Great budget saver and great pr for RedHat also.
just a thought...

== Is there a better alternative? ==

Could the children be better prepared for life learning to use, as I and MILLIONS of others had, with a BIG CHEIF tablet and a pencil (yet somehow I am computer literate now)? Total cost for pad and pencil: $2.75 ... left over for food and medical from the initial $150: $147.50.

:add to your account books. Many of them , big large books. What about movies, multimidia, are you media literate? Can you fit the all the books and movies you can see in your budget?

== Beyond education ==

These machines could be used by adults as well as kids. Surely selling crafts on ebay, checking which markets have the best prices for livestock and downloading info on AIDS would be a great use for these. Why the exclusive ocus on education, and the consequential skew to mesh networking?

== Basic concept ==

Isn't the idea of this as a laptop a bit limiting? Why can't it be a phone, a lamp, a radio or whatever too? All this could be added very cheaply, and features like the swivelly screen seem such a distraction compared to such basics. Cellphone technology would also enable this to be networked over much larger distances.

== Science curriculum ==


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.
I do not see any content related sections for the sciences (physics, chemistry, biology) and math. Can you please point me to that section or include this in your curriculum?
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.

== does OLPC not serve to widen the gap between the haves and have nots? ==


saludos
My question is, by not supporting any of the common technology in the first world, and forcing a totally unique paradigm of user interface and technology, how is it that these disadvantaged societies will become more "advantaged"? It seems that a proprietary system will only serve to make a greater distinction between the poor and the rich.

What numerical and literacy applications exist to help Kids within the Kenyan context/curriculum? mkiarie83@hotmail.com


== Problem updating from 656 and mouse freeze ==
the OLPC and its Sugar User Interface are NOT a proprietary System. The technologies are open source and built on a tried and tested Kernel and Operating System. in fact, the OLPC's use of Free/Open Source technology will serve to ensure that children are not forced to think like the ms drones of today who believe that computer literacy is knowing how to operate MS Excel. These children are being given a computer where nothing is hidden from them, the internals of the operating system are there for them to inspect, learn from, and hopefully learn to improve. the sugar ui only serves to simplify things for the children until they are ready to look further into the OS and see what makes it tick. ideally in 10 years or so, these children will have an understanding of computers that greatly exceeds the children in our own developed countries because they are not forced into a proprietary paradigm of computing. If we gave these children a copy of windows on every laptop, what purpose would that serve? they could learn to use the applications that they are given, but that is NOT What this is about. the children need to learn how computers work and why they work the way they do, this cannot be accomplished with a closed-source proprietary operating system. I believe it is especially important that these children are able to see and improve the source code of these systems, that way, when they are older and have learned enough, they will have a new outlook on computing, much different from our own. their ideas of how to interact with computers will lead to new innovative software that will benefit everyone. diversity is important and we are giving these children the opportunity to progress in their own direction without the preconcieved notions that the rest of us have from being exposed to Windows and Mac OS for so long.


Hello
to Summarize, since I rambled so much, your question is completely backwards. the disadvantage is OURS, the RICH have suffered from the proprietary nature of the Operating System that has been forced on many of us. these children are being given freedom to do as they please with their operating System, and at the same time, it will give them a firm understanding of the linux kernel and the underlying OS that will be much more beneficial to them in the future that anything microsoft or other proprietary software vendors can offer.
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

== Adaptation of Musical Editor for local music systems ==


Hello,
::Hello
::I tried using the email but only got a generic response. To answer your questions:
While browsing through the software that will be put on the B2 release, I remarked the screenshot of the Musical Editor, and I saw that it was based on the western notes system (do, re, mi, fa, sol, la, si, do). These notes have more or less fixed frequencies ('la' has 440 Hz, and going from one note to another happens by stepping of halve tones where the frequencies need to be multiplicated or divided by 1.059, the twelfth root of 2).
::- 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 OLPC project is ment for children in third world countries, like for instance India and China and other countries, where different music systems are used. Therefore I propose to foresee these adaptations within the Musical Editor (after all, it can't be the intention of forcing children to abandon their own musical culture :-?).


:::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.
In case OLPC people are interested, I am willing to do some investigation in order to figure out which are the mostly used music systems with corresponding frequencies in order to facilitate the work. I can be reached via my e-mail address under my OLPC subscription account 'scampsd'.


:::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.
Best regards and good luck with the project
Dominique


:::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. --[[User:Quozl|Quozl]] 22:24, 4 January 2011 (UTC)
Hi, we came up with this issue at the 23c3 in a lecture about the /dev/(u)random generator in Linux. The algortihm gets most of its entropy from the harddisk. Because the OLPC lacks a hdd, this could be an issue, when you need a random number for cryptography at boot time. Of course the algorithm is still strong and sufficient enough for most applications (or at least i think so), but not as good as some people maybe think. (Other entropies: camera, microphone,...)

== CHILD PROTECTION SOFTWARE ?!?!?!?! ==


== Activities disappear ==
Hi, as this laptop is geared towards children and it seems as there is no hard drive to install software into the machine. Is there child protection software installed into the device with parental pin code to activate/decativate it?


What to do if all of my activities disappear? Please Help!!!
Also if there was a simple 512mb eeprom then it would be possible to install a few applications into the machine. I am sure this would only add a couple of dollars onto the price. (just a thought).
: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. --[[User:Quozl|Quozl]] 23:38, 1 February 2011 (UTC)

== Wi-Fi WAPs not visible in Neighborhood View ==
:Few apps? Not true. Some years ago we had less than that and we could run thousands of games and applications. Maybe the problem is the applications got fat. And besides a lot of the good stuff moved to the internet, so if the child wants a full blown video editing software he can use an online app. I do not know about parental control, the child seems to have total control over the machine, even to the source code. But the UI is social-oriented so it's geared thru making the child participate community activities, which is a good community control. If you know the child is drawing with peers then he is not be seeing porn - Alexandre Van de Sande


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?
== About emulating the OLPC disk Image ==
: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)


== how to format my olcp XO 1 ==
I am not sure where to post this as it's a rather technical support like question. I am emulating the OLPC image (I am using olpc-182.zip) in a intel iMac using VMWare tools beta. The emulations runs well, but with a limited size (640 x 480) and I know the laptop goes way beyond this. I have read somewhere an email from the OLPC mailing list that this was a recurring issue and many of the blog posts with screenshots and reviews of the SUgar interface where getting it wrong because of this.
please please i can ask you how to format the olcp and how to remove the downloaded applicattion which can not be erased please if u know it tell me quickly or send it on my email : saemscolomb@yahoo.fr
: One way to clear all changes would be to re-install or update to a current version. See [[Release_notes/11.3.0#XO-1]] or [[Release_notes/11.3.1#XO-1]] (almost released). --[[User:FGrose|FGrose]] 17:27, 10 June 2012 (UTC)

== I just want to try the software ==
== Super trouble with OLPC ==


hello friends! (first pardon me with the bad English...)
I've read about the software and the UI online.
I want to try the software. I want something like a "liveCD" that I can stick
in my computer to try it out and show other people.
a) Is it possible?
b) If possible, is it explained anywhere on this eiki?
c) if yes, why is it so hard to find? A nice big link on the homepage might be nice.


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...
:Don't know if there's a LiveCD, but you can try an emulator. On the left there's a navigation bar with a section titled '''"about the laptops"''', and under it you'll find the '''[[OS images for emulation|emulation]]''' link that'll take there... That wasn't so hard, was it? Enjoy!--[[User:Xavi|Xavi]] 07:05, 5 January 2007 (EST)


NOTE # 1: the OLPC hardware test report that everything is good...
== I would desperately want to get such a computer, eventhough I'm not eligible and could easely afford a usual computer ==


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


NOTE # 3: all clean-install and bios writing processes ended correctly with no failures.
I've heard about your project on the program "Click" at BBC World.
I think the idea of a 100$ computer is absolutely marvelous!


NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.
I would desperatly like to get one of these computers myself, eventhough I can afford usual computers.
The problem is, that I'm living in Switzerland, which is still tinted grey on your world map.


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...
I would be prepared to pay double the price (200$) to get one of these computers.
That way, you could actually build two of them and donate one of them to a child that really needs it.


anyone can light any clues about what is wrong with this OLPC???
I think it would actually be a great idea to allow people who aren't eligible to own one of these computers, to get one for double its price - thus financing a free notebook for a child who really needs it.


any responses here or in my e-mail dj.electron@gmail.com with help to solve this mystery, are welcome .
It would also prevent people who are eligible to get one to put it on an auctioning site to sell them to people who don't really need them.

there are plenty of organizations that already do this, and you are free to contribute to their cause, there is no need for yet another red-cross or whatever other NPO, the goals of the OLPC have not been addressed before and many people consider education a very important cause.

:I'm all for it! But what about drinking water? That too! And medicines? No doubt! Shelter? Peace? Love? Education?

Terminal doesn't work so it isnt an option
:Not one of the aforementioned organizations can make a better world by itself, each one is needed in their domain of expertise and competence. So let the specialized organizations do what they are good for: battle the odds to make a better world in their 'little' areas of competence. They are all needed, in an interconnected set of efforts that together they stand, divided they fail...

==Request for direction to power generation discussion==
I am having a hard time finding a discussion about the '''power generator''' for the XO. Can you please direct me to the appropriate person or place? I have noticed that while my wife computes, her knee often bounces. And I wonder if that natural movement might be harnessed to generate power for the XO.


how do i use regular sites to download music?
I have calculated that such a movement of 2 to 5 cm twice a second under 100 to 200 Newtons of tension (or more naturally 1 to 2 cm at 4 Hz and 50 to 100 Newtons) could input '''2 to 40 Watts''' depending on the level of conscious effort vs. habituated movement and the ability to harness both legs. This is an old concept that was employed for '''treadle sewing machines and pump organs'''. The only difference in the case of the XO is the challenge to build it extremely portable for a few dollars, using such things as nylon straps and plastic pieces.


== installing firefox9.0.1 ==
Anyway, I would like the opportunity to follow the discussion of these concepts with the project team if possible if you would be so kind as to direct me. If it wouldn't be too much trouble, you could e-mail me using my gmail address and my first name dot last name.

Great question which I was about to ask. I live in Argentina and will be interested in seeing how many of these laptops appear on the local ebay. In a country where wi-fi hardly exists and where many poor kids don't go to school and spend their time collecting discarded cardboard and paper to sell if they're not begging, the pessimist in me fails to see how this is going to work. I can in fact see things working better in remote regions of Africa where everybody is poor, for me it seems there are going to be problems in cities where there are very poor people who will be entitled to the laptop and richer people who will perhaps want to buy it. This is all of course provided corruption in the government actually ensure the poor kids get the laptops in the first place!

== Alvin, mesh ==
Can any one ask a question here or is this just for computer programers?
If not where can the avarage person find out more about OLPC?


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


I would like to know where is the mesh protocol located on the XO? From where can I change the protocols?
I think your idea is marvelous! I heard recently about how cell phones are benefitting rural peoples in Africa, where landlines are almost non existent. and I can see how OLPC could be similarly beneficial -- perhaps more so.


Thanks in advance.
Are you are recruiting folks yet to help train teachers or children to use the laptops? I've worked as a newspaper journalist, writing instructor, and am now in marketing and public relations for a community college. But I'd like to do something more meaning and helpful on a larger scale. How can I find out if there is a use for my skills in your organization? I am willing to work oversees and in primative conditions.
: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.
== Can this laptop run on old DOS programs? ==


:::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.
There are lots of free old DOS programs out there and DOS os takes very little RAM space.


:::::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).
Is it possible to put DOS OS into this laptop?


::::::Thanks for the information earlier. Will I be able to get a chance to edit wireless module firmware? thanks
Is there any emulator under Linux to allow DOS to be used?

I am wondering why you are forcing someone in the "First World" to buy 2 of your laptops in order to obtain one. I am a disabled person living in an Amish area of Ohio where infrastructure is very sparse. Your laptop would be perfect for me, as the computer I am currently using requires a generator for power, is less powerful than your model, and forces me to move around my house to access it. (I have a hip disability and SEVERE migraine/cluster headaches, often rendering me immobile.) As I live on a limited income, I cannot afford to be buying multiple copiesof your laptop, but could possibly pay a small extra "charge" as a donation to your cause. Please let me know how I can obatin one of your wondeful laptops without being penalized for living in the U.S. Thank you.

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 mafabini@yahoo.fr je souhaite dans le cadre d'une ONG dénommée Bokk Diang avoir des partenaires pouvant permettre "d'arroser" les Ecoles Sénégalaises. merci de l'aide que vous nous apporterez. 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)

Reset settings

I need to knnow how to reset the name on my xo laptop

From the Sugar Control Panel, update your "About me" settings, and restart. 02:34, 17 December 2009 (UTC)

Viruses

How Do I erase viruses from my xo

i buy new usb to rs232 moduleboard ft232rl.and i conect my computer with my desktop but htere is nothing happnaed can some one tell me y or i conect it with other laptop not with desktop.i have olpc

reset journal info

my question is how do u erase information on the journal

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 thanks gaurav Peace out

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!

Federico

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)

Server Installation detail Guide

Can anyone out there assist me to get the eth0 working on my server. Dudley Daduwe

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.

Hola..

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)

how to format my olcp XO 1

please please i can ask you how to format the olcp and how to remove the downloaded applicattion which can not be erased please if u know it tell me quickly or send it on my email : saemscolomb@yahoo.fr

One way to clear all changes would be to re-install or update to a current version. See Release_notes/11.3.0#XO-1 or Release_notes/11.3.1#XO-1 (almost released). --FGrose 17:27, 10 June 2012 (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!!!

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)

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.

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)
