==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)

== 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)
== 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.


==Maximum Altitude Spec==
== 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 ==
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? ==
--[[User:Hunter|Hunter]] 09:55, 10 February 2007 (EST)


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?
==Usability and User Testing==
: 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?
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?
: Click on a file to download. Then open it from your [[Journal]]. Alternately, install an activity like [[Jukebox]].
I`d Like test the OLPC in Argentina, Please contct with me to know how.
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)


How do I download Doom?
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?

== Reset settings ==
==Deployment Criteria & Metrics==


I need to knnow how to reset the name on my xo laptop
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.
: From the [[Sugar Control Panel]], update your "About me" settings, and restart. 02:34, 17 December 2009 (UTC)


== Viruses ==
: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.

: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.


== reset journal info ==
::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)

== 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/ .

== How does the Log Viewer work? ==
==Support for Self-Learners==


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?
: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.


Also, is it possible to recover erased activities from the journal?
:If you can't imagine how kids can use a computer for learning in the absence of teachers then you need to read about the [http://www.greenstar.org/butterflies/Hole-in-the-Wall.htm Hole In The Wall Project] in India.

:As far as I know, OLPC keybords are standardized for each country's language/s, but not braille.

: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.

Further to the question above, does the OLPC initiative include distributing laptops to children who are currently going through patient care in a hospital setting? And if so do you have links to devices that can allow a child to utilize a laptop from a hospital bed (i.e., wall mounted mechanical laptop ARM)? This is a great initiative!!!

:Technically, it's the governments '''buying''' the laptop that will distribute them ('''not''' the OLPC), and while I see no difference between a child in a hospital bed or a cabin in the mountains (from a distribution PoV), my guess is that hospitals in these countries have other priorities to allocate their budgets instead of [http://www.infologixsys.com/products/Healthcare/Healthcare-Solutions/Point-of-Care/Wall-Mount-Workstation/C-Wallmount-Cabinet/default.asp fancy trays] (as cool as they might be ;) --[[User:Xavi|Xavi]] 08:05, 23 January 2007 (EST)



As a representative of an NGO type organization I just recently commented to a UN officer about a similar subject. “Fancy Trays”' are not always at the request of the country or donor agency in general. Part of what makes these items or services that may not at first glance seem functional is the vision of the donor. Just like the water go round in Africa sponsored by Ex US president Bill Clinton and the water see saw in another nation that promotes the washing of your hands. It is not always up to the receiver in what it is they are to receive .
There are also many sites that go in-depth about theses issues and the how and why's of the matters. If you are interested in finding out more you can direct searches about: third world programs, world aid and I am sure you can find more information as to why a fancy tray may have been purchased or donated as well as many other interesting things.

== 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.

== Self-winding generator ==

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!

:This is brilliant! My niece and nephew recently gave me a flashlight that is charged by shaking a weight back and forth through windings where the D cell batteries would go in handle of "normal" flashpoint. It is very low power LED bulb but the accumulated energy could be significant. Something similar but maybe with steel balls to roll around a racetrack or arc designed for ergonomic motions in a couple of different walking "games" would charge the power storage all the way home or to school! We need to find an ergonomics specialist to help (and maybe a child pyschologist or game specialist) and an electrical engineer to design the circuits for the generator ..... maybe we could find some soon at Wikiversity? ... or we could track down someone knowledgeable from the power summit recently held. Power summit for One Laptop Per Child project[http://lwn.net/Articles/181687/] .... I am not sure how to proceed. I am currently trying to get a pedagogy project going http://en.wikiversity.org/wiki/Self_Paced_Reading_Labs.

== 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.

== 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)?

Wouldn't adding those extra features also significantly increase the price of the OLPC as well? Why not use the OLPC's built-in wifi adapter to track the signal and MAC address instead?

Wifi adapter as an anti-theft device?

yes I agree. I also think it would be useful to turn the built-in wifi adapter as an anti-theft device. The adapter should be made to start mandatorily at boot up and not allowed to disable it so that in the event that the laptop is stolen it will be trackable by using war driving software.

== 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.

:This question ignores a very important part of the economic equation. Textbooks. The cost of primary school textbooks is kept hidden from most of us but a trip to a college bookstore will show you that textbooks cost a lot of money. The primary economic enabler of the OLPC laptops is that they allow textbooks to be distributed very cheaply. Compared to physical textbooks, electronic ones don't have to be printed and they can be shipped on very low-weight media such as CD-ROMs. Of course, in order to realize the economic benefit of electronic textbooks, you first have to invest in an e-book reader. That is the core of the OLPC project. If you investigate existing e-book reader projects you will dicsover that they are all based around a general-purpose computer with some software that restricts the capabilities to only reading books. The OLPC project goal is to create an e-book reader that exploits as many of the capabilities of the hardware as possible. The end-result is a single device that can serve many different educational functions and is versatile enough to be used throughout the student's educational life and beyond. --[[User:Memracom|Memracom]] 05:15, 13 January 2007 (EST)

== 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?

--And if the IT companies can offer the kids after-school paid assignments like light programming and data entry tasks for like 1-2 hrs a day, it will also solve the problem of the kids or their parents selling the laptops for food money

JK, USA

:First, the OLPC laptops have no Internet access and the users likely will not speak English. Forget ebay. Second, you point out that the devices would be great for educating about AIDS and then ask, "Why the focus on education?". Thirdly you suggest that kids could do "light programming" to earn money but you ignore the fact that education is required to be a programmer. India is an example of this. It has a good education system producing many skilled programmers who were unable to find work locally. This was exploited by foreign companies who offshored their programming needs. But it all began with "education". Now, perhaps you see why the OLPC project focus is on education first. --[[User:Memracom|Memracom]] 05:14, 13 January 2007 (EST)

---Yes but you cant ignore Maslow's hierarchy of needs. A starving kid with a starving family at home will not see OLPC as an education tool but instead as something he can sell to buy food. Exploitation in India by international IT companies may be morally wrong by the developed world standards but the alternative for indian programmers to that kind of exploitation is unemployment. I'm not ignoring the fact that one needs education to be a programmer, OLPC can provide that education. "Education first" slogan sounds great, but realistically speaking you can't skip the layers in Maslow's hierarchy of needs.

::The interesting thing about Maslow and technology is that it sometimes results are ''counter-intuitive''. For example, many reports have been written about how cell-phone technology actually has improved the standard of living for subsistence farmers, fishermen, etc. because they extend one basic need: communication & mobility (two things targeted by the laptop). --[[User:Xavi|Xavi]] 08:58, 17 January 2007 (EST)

== 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.


because a phone, a lamp, or a radio doesn't make a great learning tool like a laptop does. Cellphones have limited capabilities like the screensize, lack of fullsize keyboard, costly airtimes, data storage etc. A radio doesn't allow interactive learning like a laptop does. A lamp is a necessity but with the LCD screen in the laptop the child will be able to read and do his homework in dark. OLPC project isn't about providing them with life's basic necessities, it's about giving children a great tool for education so that they can learn skills to end povery and hunger in their communities in future.

JK, USA

:Indeed the idea of this as a laptop is a bit limiting. The OLPC project has put a considerable effort into making this much more than a laptop. If a student wants to use it as a lamp, they can because they are the producers of the electricity required. If they want to communicate with their friends, not only can they send text messages and SVG drawings, they can also record messages and share activities that they have programmed. This is far more flexible than existing cellular phones. The main thing missing is the long range communications ability of cellular but since that comes with a very steep fee per minute of use, it won't be missed. Because the OLPC laptop is an open system it will allow people to build low-cost cellular bypass systems like [[Motoman]].--[[User:Memracom|Memracom]] 05:21, 13 January 2007 (EST)

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.

--Ryan Cameron, [http://www.habermanfoundation.org Haberman Educational Foundation]



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.

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.

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

Hello,
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).

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 :-?).

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 OLPC includes [[csound]] software which can be adapted to work with any type of musical system. If you want to document these systems and any csound software that works with them, feel free to start a new page on this wiki. --[[User:Memracom|Memracom]] 05:30, 13 January 2007 (EST)

== Random generator entropy ==

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,...)

== About emulating the OLPC disk Image ==

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.

I wanted to investigate this further (and help correct those blog reviews) and posted this question to the VMWare foruns, but they believe it's a problem with the OS image.

Any insights on this?

thank you

== I would desperately want to get such a computer, eventhough I'm not eligible and could easely afford a usual computer ==

Hello!

I've heard about your project on the program "Click" at BBC World.
I think the idea of a 100$ computer is absolutely marvelous!

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.

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.

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.

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.

Thanks for a reply!

Best Regards

C.Beeli - Switzerland

:It's good to read about your enthusiasm, but alas, quite some people had similar ideas before as the "[[Ask OLPC a Question about Distribution#Availability - Can XXX in YYY get one paying ZZZ ?]]" section shows, and to which the short answer is '''no'''. A longer answer is that you can still participate and collaborate with time and effort to make the project a reality. And a full answer would be this whole wiki, your government, local NGOs, etc. --[[User:Xavi|Xavi]] 07:23, 5 January 2007 (EST)

== Food For Children ==

Shouldn't we be making sure that there is at least one meal per child rather than one laptop?

--

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. "teach a man to fish"

:I'm all for it! But what about drinking water? That too! And medicines? No doubt! Shelter? Peace? Love? Education? ''We'' is a lot of people (sometimes, the whole 6.5 billion)... much in the same way that specific organizations try to bring medicine to the dispossessed (ie: [http://www.msf.org/ Medecins sans frontieres]), or fight for their human rights (ie: [http://www.amnesty.org/ Amnesty International]), provide better feeding and agriculture technologies (or emergency rations) (ie: [http://www.fao.org/ FAO / UN]), and education (ie: [http://www.unesco.org/ UNESCO]), the OLPC is trying to get this 'simple gadget' (a full blown laptop) into the hands of kids for them to learn, communicate, interact, and many other things...
: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... (I know, it should read 'fall', but in development issues, it usually and nonchalantly fails).--[[User:Xavi|Xavi]] 12:27, 5 January 2007 (EST)


Can we look at them as two approaches to solve short-term and long-term problems of the developing world? Giving basic needs to the poor & needy in the 3rd world = helping them with their immediate needs while giving them OLPCs = investing in a better future for them and their societies. While I agree with Maslow's hierarchy of needs we must also realize that teaching IT to children in the 3rd world countries is equally important so that hopefully one day they can use that knowledge/skills to get out of poverty and hunger.

==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.

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.

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.

Thanks.
Tom Haws

:Most of this is discussed on the [[Battery and power]] page. The OLPC laptop doesn't have a built-in power generator. Instead, it has a DC power input that will accept a wide range of voltage with protection against polarity reversal. This means that any number of alternate power sources can be used. We will be shipping a hand-powered generator with the initial devices but we are open to any new ideas, especially if they are backed up with prototypes and with some solid research showing how they are used by kids in the field. In addition, if a device can be built by the kids (with the help of their teachers) then it would be appropriate to provide detailled building instructions in one of the [[Ebooks|Ebook formats]] that we support. --[[User:Memracom|Memracom]] 05:37, 13 January 2007 (EST)

== What about OUR children in the US? ==

I am tired of us giving and giving to other countries. What children right here in the United States? I teach in a poor Appalachian school district in Eastern Ohio and our children don't have computers. I have 2 computers in my classroom and one is very, very old. My own students do not get to use a computer, so why are we giving to other countries?

:Nobody is asking you to give anything! As a matter of fact, the 'other countries' are '''investing'''. So, if you're tired, sit back, relax, and [http://www.fair.org/index.php?page=2676 read this] or you can lobby together with [[OLPC4USA]] '''your''' government to invest... --[[User:Xavi|Xavi]] 16:02, 7 January 2007 (EST)


May be a project similar to OLPC can be initiated to narrow the digital divide in the US. But instead of inventing a whole new laptop like the OLPC old PCs and laptops can be recycled and install linux to save cost? You'll find that when you run Linux on old computers they're not so "old." :-)

== Black Market ==

How do you plan to fight the black market of this computers? They more or less cost $100 each, and in many of the countries mentioned, families could try to sell them to buy food or fullfill any other basic need.

*This will be the responsibility of the country in which the laptops are deployed. They are more familiar with local culture, local social issues and local laws.

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'd like to help teach. ==

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.

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.

:The OLPC does not actually deploy the computers in these countries. If you want to work in the field, then start by reading our news section to see where the first computers are headed. Then contact the ministry of education in one of these countries to offer your services. They will likely be working together with one or more charitable organizations who operate in their country. Currently, Brazil, Libya and Rwanda are target countries. --[[User:Memracom|Memracom]] 05:40, 13 January 2007 (EST)





== Governments & schools - a western construct ==

Schools are nothing more than a western construct which the developed world seems hellbent on imposing on the devloping world even if the result is social destruction. Governments of all complections have a vested interest in exploiting this project. It seems to me that there is a desperate need to develop a new pedogogy involving non-traditional formal educational structures, possibly working with NGOs. Governments in developing countries will go the same way as many western governments and impose a nationalised curriculum which will be delivered via these laptops.

:First, the OLPC project is not developing new schools to be delivered to these countries. We are developing laptop computers to be delivered to children. The laptops themselves will be a rich educational environment even in the absence of teachers. In addition, the philosophy that we follow is a [[constructivist]] educational philosophy which focuses on leading the child to discover knowledge for themselves. --[[User:Memracom|Memracom]] 05:45, 13 January 2007 (EST)

I think the "Buy two get one free" idea is great because consumer demand for the OLPC will drive the production to mass numbers and it will help the future availability of used spare parts for service needs. I would also like to suggest for the creation of an online database where OLPC users in need of replacement parts can find donors and order them online.

:There is no "Buy two get one free" idea. Check the [[Retail]] page for details. As for spare parts, the OLPC project is recommending that recipient countries maintain a reasonable level of spares for the computers that they receive. --[[User:Memracom|Memracom]] 05:45, 13 January 2007 (EST)

== Rugged Laptops ==

There is a huge market for basic rugged laptops for use "in the field" in a number of industries. These would be cases that don't need the full functionality of e.g. a Panasonic Toughbook, and where basic will do and cost is critical. Develop a suite of work-related applications and/or provide certification for apps developed by others, and sell those on CD at reasonable cost, to bring in more money for free laptops for kids.

The basic arrangement would be: Companies buy laptops at e.g. $200 per unit plus a required $200 per unit tax-deductible donation to the nonprofit foundation. Thus the effective cost is $400 per unit, but half of it is a tax deduction. If you do this, companies will buy these things in huge numbers and thereby pay for equivalent numbers of machines to be given away to kids.

:'Huge' is relative, you can measure it in number of units or monetary value. And given that the market is a niche, it implies a small volume and high monetary value&mdash;the opposite of what the OLPC target market is (afaik). I see your point in 'overpricing' this 'commercial rugged laptops', but that would only create incentives to divert machines to the black/grey market. --[[User:Xavi|Xavi]] 15:10, 13 January 2007 (EST)

== School Gateways follow follow up ==

Thank you very much for the response on School Gateways -- I had a big misconception about the internet. I am still curious, however, about how the School Gateways for the mesh networks are intended to be powered, and how much energy they will require. I looked at the power page, and it mentioned microbial fuel cells, which is what I was going to ask about. Are the gateways going to require a lot more power than a microbial fuel cell could provide? Thank you!


---(JK, USA) There ought to be a sister project of the OLPC to bring internet connection to schools in the developing world. One internet connection per school wouldn't be a bad name for such project. Wireless Gateway/APs powered by environmentally friendly and renewable energy sources like solar or wind power, perhaps linked to a bidirectional satellite internet receiver, and then use [http://wifipaypal.sourceforge.net/]WifiPaypal so that donors in the developed world can donate mothly Satellite connection bill direct to the schools using Paypal.

*I think you should develop your idea and get about doing it. Gus, Chile

Yes, that would be great to get internet capabilities, I agree -- I hope you do start that up!

Does anybody know about the approximate power needs for the gateways? I know somebody working on microbial fuel cells and he asked me to find out what the power needs would be, and I just have no idea. I'm assuming that power is going to be a biggish issue for the gateways, as many of them will be in areas with no elecricity -- Am I wrong? Thank you!

== One Laptop Per how old? Child ==

We're saying One Laptop Per Child, but how old does a child have to be to qualify? Attending school? How old is that? I know, personally, of 3 year old children who could make good use of this device.
:Generally ages 6 to 17. (First grade to the end of high school in the US.) The emphasis is ages 6 to 10 or so. A careful look at OLPC pictures indicates that they are really sized for 6 to 10 year olds. --[[User:Tef|tef]] 13 Jan 2007

== Regular Laptops as OLPC Clones? ==



I think the OLPC OS and all the software should be made to run on regular x86 laptops and distributed freely. One benefit of making the OS and software opensource and multiplatform compatible will be that the kids will be able to run it on donated used laptops until there are enough OLPCs for everychild :-)

== Is the 'buy 2 and get 1' scheme going to happen? ==

Hi there,
Is the 'buy 2 and get 1' scheme going to happen or not? There have been many reports that suggested that it was planned for next year.

:There is no "buy 2 get 1" scheme. If you would read the [[Retail]] page then you would know this.

I think this whole idea of connecting receipient with donor and the distribution over ebay is a really fresh and clever idea of you.

:This is not an OLPC idea. The OLPC project has no intention to distribute laptops over Ebay and if people started to sell stolen laptops on Ebay we would work to shut that down.

==Relaunching software as freeware==
We are reviving ChipWits - an award-winning iconic programming game - and would like to encourage a freeware version to be developed for the OLPC. Is there a forum to discuss it?

== Tested with destructive children? ==

Regardless of cultural background, everywhere these laptops will go there will be some children who'll break anything they get their hands on within a few days or even minutes.

Have these two tests been conducted with actual children?

Rotate the screen 90 degrees then have various children attempt to push the screen down as if it was going to be closed normally or in e-book position. If the hinge breaks then it's not strong enough.

The angry child test. Anyone who has ever seen kids get upset at not being able to figure out a toy or game or puzzle and *has not* seen at least one kid hurl the thing across the room or swat it off a table hasn't been around enough children. With the screen in various positions, test it from merely dropping to the floor from table height to being shoved off at various speeds. To gather velocity data, have various children push and throw test objects of size and weight similar to the current BTest laptop design, then use that data with a pusher device on an actual BTest laptop.

One possibility may be to build in some amount of flexibility, similar to spring hinges on eyeglasses, or make a non-twist design for the youngest children. Put some glasses frames on some kids then have them play volleyball. Mix the frames half with spring hinges, half without. Observe the effect of a volleyball to the head and what happens to the frames. (Having your frames broken three times in three consecutive games is a great way to convinve the parents to spend the extra $ on frames with spring hinges!)

Another possible way to reduce damage potential is to make the hinge with a cam action so that it can only be twisted around when it's open to 90 degrees, and attempting to turn it when it's open more or less will push the screen to 90 degrees before allowing it to rotate very far. Joints like this are used in many products already, to ensure the joint can only be manipulated in paths that will work properly. Examine as many existing twist screen laptops as possible to see if any already have such 'forced path' screen hinges. Couple this with a simple spring loaded, double acting "saloon door" type hinge between the screen and the twist and fold hinge already on the BTest laptops could make the hinge system extremely tough.

What could be a bit of a compromise system is to design the screen to 'breakaway' from the top of the hinge, with a reinforced data cable and a braided steel cable for extra durability. The screen could be easily snapped back on, but durability of the snap joint could be an issue, especially if the snap together parts are plastic.

The idea that all or most children who're growing up with next to nothing will give these laptops super loving care is major 'blue sky'. The twist hinge is a big potential failure point. One big thing anyone working on any complex system has to keep in mind is that the more points of potential failure there are, the more likely there will be failures.

Design the screen hinge to take abuse and there will be minimal problems with the abuse it will definately recieve. Leave it with the current hinge design and you'll be seeing plenty coming back with broken hinges.


'''True but...'''
I would like to add that based on the statement '''“Cultural Background”''' there is in some ways a much more stronger type life style that many that will be eligible for the lap top live.
But because it is a learning program with a parable infrastructure their has to be in the distribution and training of those who will hand them out a part about responsibility.
It should be explained to each child in their groups of receiving the Laptop that if it breaks there is a chance that they may not get another ,as only one lap top per child or family. Since it is the government and their sponsors that are to foot the bill,
this is a very serious consideration. Creating a
lesson plan with in the training material about
the ups and downs of the unit if it brakes. Can '''One:'''
Move the government too, with in their budget to acquire
parts and as well as service contracts in how long
they will support the Laptop if it breaks. '''Two:'''
Where locally will they be able to bring the
laptop in for service. '''Three:''' be prepared
for local people to get in on the act and tinker with the laptop if it is a hinge and find ways to fix it. I also think your expression about child anger was some what misleading and misinformed.
I think the possibility of a goat
or farm animal stepping on the lap top
that belonged to a child that had brought the lap top along to do family chores could be a better scenario
I believe this is much more realistic.
I don't think presenting such negative
leads towards aggression ,as to have faith in
the little children that they are good and can handle the responsibility of caring for their new
computer friend.
I hope in the future to share my
experience based on countless hours of research
in to the presentation of third world issues
that there are some inconsistencies in what is presented by media in general and the real life of that matter.
This is also a generalization as in all walks
of life the real truth can only be known by the
actors and witness of the fact at hand.

I downloaded a few of the recent LiveCD image builds (231), but for some reason the system does not load up and run. Obviously in this case you need a PC that has a CD/DVD reader etc. I may not be burning the CD correctly although Grub seems to start ok.
Is there any particular hardware needed that a typical PC does not have, or something that I am not doing properly? Anyone out there that has this working and can share some ideas would be great. Thanks in advance.

We are opening aprivate school in the village of Cherekula Uganda. I was going to provide two laptop computers but we are facing a problem with the lack of electrical power. We are exploring the purchase of a gas generator. I have bee folling the OLPC project for seceral years and am now convinced this is a better alternative. How do I enlist the Ugandan government so that I can take sveral OLPC computers to the choll when we visit this March (2007). We are completely willing to purchase them and we can transport the or have them shipped. I know that these would be pilots (beta?). We just want to try and get moving ahead on providing internet access to some very deprived children. This school is a high school. The first one ever in this village. It is located about 250 km from Kampala. Can you advise me on how to proceed. We can document the school i required. THanks ./Jim May jimlind@ameritech.net Farmington Hills Mi. USA 48336


hoy dia los costos bajando y ojala en tiempos proximos alcancen un precio infimo como para poder incorporar mas almacenamiento.
:You are going at this the wrong way. The first thing you need to do is find someone who is an expert in electrical power generation and storage to give you advice. They are unlikely to suggest buying a gas-powered generator for two laptops. Ten years ago people in Africa were running laptops off car batteries that were charged up by bicycle-driven generators. You should be doing something similar today. That means choosing older laptops with lower power consumption, choosing laptops that run off 12 volts DC (like RV owners and yachtsmen do) and then getting a generator rigged from old car parts. The one thing different today from 10 years ago is that solar panels are a viable source for charging the batteries.

:Forget the OLPC. You cannot buy them ([[Retail]]) and you need to get your government's support in order to get access to them.

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
Either send an email or write a letter with your concerns. If you can include a screenshot of your screen that would help.


: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)
== Investing ==


::Hello
How can an individual make an investment in the stock options?
::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.
:There are no stocks or stock options to invest in.


:::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.
== What about students k-12 and college students in the USA? ==


:::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.
Do I qualify? I filled out the fafsa forms do you need those to determine those for financial need? If so, is there a way I can pass the computer to another "financial need base" student? I see that your organization goes around the world but didn't know if you were including the United States.


:::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.
:There are no plans to distribute the OLPC computers in the USA. If you want to lobby for this to happen, then read [[OLPC4USA]].


:::Feel free to send me an e-mail at quozl@laptop.org if you like. --[[User:Quozl|Quozl]] 22:24, 4 January 2011 (UTC)

dear sir/madam;


== Activities disappear ==
i am a mother of two from the Philippines, my eldest son is only 4 yrs. old, he's now at the nursery level, and i notice that he is interested about computers, he even know how to operate my laptop and start his educational game and i am proud of it. that is why i am asking you a question if i can get one for my eldest son so he can pursue his interest in studying by using laptop, and soon will teach his baby brother to use it.


What to do if all of my activities disappear? Please Help!!!
thank you very much,

== Wi-Fi WAPs not visible in Neighborhood View ==
== freifunk.net volunteers ==


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?
I wrote an e-mail to volunteers@laptop.org
: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)

== Information about OLPC for people in pure countries ==


Conecté un Mp4 a mi XO 1.5 ( Secundaria ) Y creo que me entró un virus, Entonces, No me deja ver el Escritorio. Me aparece en Blanco. :(
There is lots of written material about OLPC for people in rich countries.
me gustaría saber s puedo hacer algo para sacarlo!
The newspapers are full of OLPC stories.
Me ayudan?
People in pure counties don't know much about OLPC but maybe the children will
receive a laptop in near future.


== Super trouble with OLPC ==
I will be in SO Asia for some month and will be in contact with teachers (as I am), mayors, children,...
I like it to talk about this project with these people. There is lots of information about the
project like technical specification, pedagogic methods,...


hello friends! (first pardon me with the bad English...)
But the thing I'm looking for is a simple description of the project in easy English that is use full
for the local people.


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...
2-3 Pages in PDF would be great - does this already exist?

NOTE # 1: the OLPC hardware test report that everything is good...
Hello, I'm Laura Barsottini, an italian journalist. I would like to know if is true that the laptop will be distribuited in april 2007. If not, when will be distribuited? At 130$ at the beginning? When it will be possible to begin the 2 for 1?
Thenk you
Laura Barsottini


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


NOTE # 3: all clean-install and bios writing processes ended correctly with no failures.
We are developing some applications that can be used to education purpose and we have some doubts:
- Is it possible to make applications download using the OLPC ?
- Is it possible to run the RealPlayer in OLPC ?
Thanks in advance
Vivian
(vivianlona@hotmail.com)


NOTE # 4: the battery is fully charged, and the AC adapter is in outstanding performance.
:The OLPC is based on downloadable activities, not applications. It will not have any RealPlayer support so you will need to encode in an open-source format. Ogg/Vorbis is good for music while Ogg/Speex is better for pure voice recordings. Read the [[Activity bundles]] page to see how to program a downloadable activity in Python.


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...
:: What format do you require? RealPlayer can play many different formats. Quicktime can be played with [http://gstreamer.net/ GStreamer] through [http://www.openquicktime.org/ OpenQuicktime] and [http://www.gnu.org/software/gnash/ Gnash] is mostly SWF v7 compliant (this makes Flash an open-source format).

Hello!!!
== Economies of scale? ==


I have XO 1.5 and want to erase all data from the journal. I know that there is command (maybe not one) that is being typed in terminal for erasing all data from the journal. But cant remember that command. Can somebody help?
How would it not be in your interests if you hired a non-profit-org to sell laptops to citizens of more rich countries?


Thanks....
You claim that it has to do with scale and all, but do you understand how many of these would sell? I'm sitting in front of a dual AMD turion laptop, yet I'd love the idea of having a laptop for my room and car both. You could sell millions of these here in the states. Would that not be scale for you? What # are you looking at would be for "scale" to occur?


== activities wont work ==
You all just need a web presence. Im sure one of the major credit card holders would give you a break, if not free processing for the purchase. I'm assuming that you already have warehouse space to store these things, so all you'd need is a volunteer army to ship them out. Not that hard, when you can make a fair profit back (or pay the "volunteers").


everything i click on wont load except; firefox, doom, scratch and produce puzzle
150$ would be a very fair price point for those blessed with wealth in the States. I'd probably still buy 2 if they were 200$.
E toys will load but, there will be an error message, and it will just be a blank page.
How do i fix it?!!!

:This is not so much of answer given that I ignore the details, '''thus I'm assuming'''.
:It would seem that the deal struck between the OLPC and [[Quanta]] is ~USD 135 per unit EXW / FOB for a minimum order of 5 million units. So the OLPC has to ensure ''at least'' a 5 million order, before Quanta pushes the go button. Afaik, that is the "scale" needed.
:You say how many could be sold? I have no clue really, but taking from the [[Retail#Pledgebank|3,678 pledged]] at the failed [http://www.pledgebank.com/100laptop pledgebank.com]... I don't see that number growing into a significant chunk of the 5,000,000 required.
:You say hire an NGO, who'll pay for it? Self-financing you say? Maybe (but retail distribution is not that cheap) so in the end, much of the effort and (possible) profit will go to support the retail market. Maybe as PR activity, draw attention and support, developer community mind-share, and such&mdash;but that's another game. BTW, it takes a lot more than just a simple web-presence, credit card processing and stamp-licking-volunteers to get the boxes somewhere.
:Warehouses? None that I know of. Afaik, OLPC is not even remotely interested in the distribution logistics. So even after [[Quanta]] hits the go-button, you still have the enormous task of actually distributing them&mdash;afaik, each country is responsible of doing their part.
:Devoting and/or diverting efforts aimed at the [[retail]] market is not simple, and it would strain the launch process. Remember that ''it's an education project, not a laptop project.'' So even if you manage a retail market for 5 million units, the [[Our mission|project's objectives]] will '''still be unsatisfied'''.--[[User:Xavi|Xavi]] 13:02, 1 February 2007 (EST)

Terminal doesn't work so it isnt an option

At launch time will the laptop include any software for content controls (to prevent porn, etc). I realize that one's definition of "acceptable content" varies over regions, but isn't most content filtering software for the client Win-based?


how do i use regular sites to download music?
: This will, as far as I know, be left up to countries. Because the hardware and software OLPC will provide is as open as possible, there is no real way to implement such filtering on the laptops themselves; the kids could just change the software to get around such restrictions. --[[User:18.85.46.22|18.85.46.22]] 19:16, 17 February 2007 (EST)

== una pequeña ayuda con una olpc ==
== Environmental End-of-life considerations ==


hola como estan
The environmental impacts and economic costs of disposing of obsolete/broken ICT hardware are well-known. The energy-efficiency of the laptop helps minimise it's impact during operational life. Can some details be given on steps that have or will be taken in the manufacturing and "ultimate disposal" stages of the hardware lifecycle to minimise environmental costs? I'm thinking here of embedded energy in manufacture, and disposal costs. Will recycling costs/incentives be built into the purchase cost? Will a recovery program be up to the individual government , or part of the agreement between OLPC and clients?

[[Image:Clipboard Ops.jpg|thumb|Editing the Wiki via an XO]]


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.
* One of our XOs (among the first 40 units to arrive in Nigeria) nicknamed '''alteq eng 1''' is displaying some anomalous behavior: Whenever its browser and RSS viewer (Penguin TV) are launched, their icons slowly/gently "flash" in the "circle of running applications". Whenever the flashing Penguin TV icon or Browser icon is clicked on, they each disappear.

Thank you,

Alfonso Calero (a_bellorin@hotmail.com)
*The '''MeshNets''' don't always work as expected; sometimes, some of the XOs indicate that their MeshNets are active...yet they don't see one another...particularly those XOs that have been "tagged" as "friends". I usually solve this by restarting.


== Alvin, mesh ==
* When an application or more is shared on the MeshNet, another XO that clicks on the shared application (in the neighborhood "radar") will have its respective application launched but won't have a view of the content from the host XO that shared its application. For instance, if XO "Alpha" is viewing the web page '''http://uk.360.yahoo.com/wingless_pilot''' and it shares its browser, XO "Beta" can see "Alpha's" shared browser on the neighborhood radar and click on it. Whenever this is done on the XOs at Alteq (OLPC4Nigeria), "Beta" and any other XO that clicks on "Alpha's" shared browser will end up having their respective browsers going to their default URLs instead of the page that XO "Alpha" is viewing (http://uk.360.yahoo.com/wingless_pilot).


I have a couple of XO's with me. I would like to change the network protocols and analyze the results.
My observations were posted onto this page using an XO (copy-and-paste from Abiword to browser).

: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)

:::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).

:::::::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)
:We have seen a few cases of auto-installer failures apparently due to "botched" downloads onto USB disks. We plan to mitigate that by including a manifest in the installer image, with checksums/hashes.

::::::::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.

:::::::::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)
I am doing an economics project regarding the OLPC as an economic policy to solve third world education. I was just wondering if you could provide me with answers regarding these questions, espsecially about the long-term and short-term costs including social, political, and economic, domestic and international.


::::::::::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)
: The costs of implementation are just those you'd expect: infrastructure, hardware, distribution, etc. I'm not sure what you're asking about "economic costs of not implementing"; the idea is that economic benefits of education vastly outweigh the costs of laptops. National governments will pay, for the moment, though other schemes, such as one nation helping to pay for another's laptops, etc. will undoubtedly be explored as the program expands. --[[User:Jacobolus|Jacobolus]] 19:34, 17 February 2007 (EST)

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.

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!

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)

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.

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)
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.

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)
