==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? |

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) |

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. |
|||
== |
== 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...

== your disk is full == |
|||
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? |

|||
==Deployment Criteria & Metrics== |
|||
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? |
|||
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. |
|||
: 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? |
|||
: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. |
|||
: Click on a file to download. Then open it from your [[Journal]]. Alternately, install an activity like [[Jukebox]]. |
|||
How do I download Doom? |
|||
::I think that spanish speaking latin american countries do fit in a gray-zone there; there are many that individually would have to wait for later stages, but together they could probably put something - ie: central american countries. |
|||

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

::Seriousness is good. Transparency too. :) I've somehow managed to reach the [[Pilot Projects#Diversity Matrix]], which I find a bit shallow and unstructured for my taste, so I'm assuming that more structured guidelines are being thought out, planned and to be published, right? After all, as the proposers of the idea, the performance analysis and other measurements should be your domain of expertise. For example, which population segment is known to make the most out of the laptop experience? Is income considered a (key) factor? People with very-low, low, medium, high, or very-high income are 'all equal' or they somehow 'profit' differently in respect to their original educational levels? Under all circumstances? |

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. |

== Two activities == |
|||
: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. |

== How does the Log Viewer work? == |
|||
==Accessibility== |
|||
Dear Sir/Madam, |
|||
What mechanism olpc is going to adopt to make it accessable for child with physical disabilities? Will there be seperate keyboards for blind with braile? Will there be alternate input methods for child with dysfunctioning hands? |
|||
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? |
|||
:As far as I know, OLPC keybords are standardized for each country's language/s, but not braille. The OLPC has [[Hardware specification#Specifications|3 USB ports]] to which external (braille) keyboards may be connected ([http://www.google.com/search?client=opera&rls=en&q=usb+braille+keyboard&sourceid=opera&ie=utf-8&oe=utf-8 quick search] and [http://www.portset.co.uk/braillekey1.htm sample result] or [http://www.hooleon.com/menu-stickers-braille.htm?gclid=CNWevcfho4kCFSiANAodGG3twA alternative method]).

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. |

|||
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. |

:Uh? Not only this question was out of place, but also, dare say, conceptually. OLPC = One Laptop Per CHILD. In the best of worlds, it would be One Laptop Per CITIZEN—regardless of nationality, age, etc. but it's not the case. Children are the priority, and in developing countries. |

== Problem updating from 656 and mouse freeze == |

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)? |

Hello |

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? |
|||
::Hello |
|||
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. |

::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. |

== Nicholas Negroponte == |
|||
:::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. |
|||
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 |
|||
:::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. |

== Activities disappear == |
|||
: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) |

== my xo1 olpc can not start up == |

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? |
|||
my xo1 olpc can not start up |

--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 |

when i open it the screen to make withe color only |

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

JK, USA |

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? |
|||
: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) |

:This will happen if automatic power management is enabled, which is the default, and the laptop is not kept awake for at least a minute. This is in the [http://wiki.laptop.org/go/Release_notes/10.1.3#XO-1_Automatic_power_management_issues release notes]. Try turning off automatic power management in the control panel. If that does not change things, please use Open Firmware to check the wireless card. Obtain the [[Ok]] prompt, and type ''scan-wifi'' then press return. This scans for wireless access points by turning on the radio receiver in the wireless card. Doing this test in Open Firmware is useful, because it excludes the 10.1.3 software entirely. If it doesn't show any access points, then there's no chance that 10.1.3 will. If it does show them, but 10.1.3 does not, then at least we know the problem is not hardware. Let us know how you go, because based on this test there are very different further tests to make. --[[User:Quozl|Quozl]] 23:20, 4 May 2011 (UTC) |

== How to repair olcp == |
|||
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. |

Hi olcp i want to repair my olcp the problem is that when i charge my olcp the orange color which shows you that the power is going in but it shows like it is charged but it is activated the xo is loading when the circles are surrounded xo the laptop turns off so how can you help me to fix it. |
|||
== my olcp can not start up == |
|||
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 lap 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. |

: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) |

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... |

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. |

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. |

Hello!!! |

== Adaptation of Musical Editor for local music systems == |
|||
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? |
|||
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). |
|||
Thanks.... |
|||
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 :-?). |
|||
== activities wont work == |
|||
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'. |

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,...)

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. |

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). |

Can we look at them as two separate issues instead? Giving basic needs to the poor & needy in the 3rd world = helping them with their immediate needs while giving them OLPCs = providing them with a technological learning tool to help prepare for a better future. 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. |

: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) |

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. |
|||
One solution could be distributing them strategically first to children covered on basic needs, all the way to the least covered. |
|||
Thank you and sorry if you have already talk about this. |

The blackmarket for donated items has always existed in third world countries and especially a high-value item (by 3rd wolrd standards) like the OLPC will not be an exception. However, I think combination of social and technological solutions can help reduce this problem: |
|||
(1) The OLPCs should be kept in school unless there's an absolute need for the child to take it home (i.e. homework assignments, exams). Also at the initial issue of the OLPC parents should be required to sign a promissory note agreeing to take care of it. |
|||
(2) If the wifi adapter in the OLPC is made to turn on automatically at bootup then the unit will be trackable by detecting the wifi signal and MAC address. |
|||
(3) The "Buy two give one free" program will help reduce the demand for the OLPC as a cheap substitute for a used laptop in the developed world. If it costs more than a used laptop with comparable or more powerful components that will reduce the demand in the blackmarket too. |
|||
(4) depending on the number of theft incidents in each OLPC participant country, the local governments can launch public awareness advertisement campaigns to educate the public that stealing an OLPC is like stealing a child's future. |
|||
(5) The OLPC campaign can ask online auctions like Ebay to ban/restrict the resale of OLPCs online. |

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

== about the ic 321j50 == |
|||
What is the purpose IC 321j50 manufactured by your company? |
|||
:I am not aware of any such IC associated with OLPC. Can you please cite a source of reference for this question? |
|||
Who is Nicholas Negroponte? |
|||
:Prof. Negroponte is the CEO of OLPC (Please refer to http://www.laptop.org/people.en_US.html for more details). |
|||
What is an XO machine? |
|||
:Please refer to [[The Children's Machine]] in this wiki. |
|||
What school-focused framework is this article talking about? |
|||
:I am not sure what article you refer to when you say "this article." There is an introduction to the OLPC [[Learning Vision]] in this wiki. --[[User:Walter|Walter]] 08:40, 8 January 2007 (EST) |
|||
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) |

== Gambia == |
|||
Can anyone tell me if Gambia is among the countries where the Ministry of Education has expressed an interest in this laptop project? Since it is such a small country (situated along the Gambia river in Senegal), I can't tell from the map. |
|||
:I '''think''' that Gambia's status is 'orange' (''those countries who have expressed interest at the Ministry-of-Education level or higher''). Another (unofficial) way of checking the status is [[OLPC Status by Country]]. |
|||
:This question should've been placed in [[Ask OLPC a Question about Countries]] and will soon be moved there.--[[User:Xavi|Xavi]] 10:04, 10 January 2007 (EST) |
|||
:Indeed, Gambia is 'orange'. BTW, there is a higher-resolution version of the map in the wiki: [[Image:olpcmap.gif|thumb]]. --[[User:Walter|Walter]] 11:19, 10 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—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 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! |
|||
== 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? == |
|||
:::::::Chance: 0.1% Because it is in the firmware, you cannot practically change the mesh protocol. The firmware is the property of Marvell. The source code is not public. The firmware is in the file usb8388.bin which is stored on the laptop. The file is sent to the wireless module after power is turned on. There is no public documentation for the ARM and baseband processor on the module, and these chips are from a silicon design around 2005, and probably no longer available. The module is soldered to the main board. --[[User:Quozl|Quozl]] 04:58, 9 April 2013 (UTC) |
|||
::::::::Hello, I have some more questions. The network is usually organised in a few layers, traditionally in seven. The lowest layer is the physical layer. That is indeed firmware and cannot be edited. Above that we have the data link, network, and transport layer. Routing will happen in one of these layers, usually in the network, sometimes in the data link layer. Question is: where is the routing taking place for the OLPC XO-1 and the other versions of OLPC XO (like XO-1.5 ..etc). thanks. |
|||
:::::::::We use TCP/IP for networking on OLPC XO, and TCP/IP is not based on a seven layer model. Wikipedia has an [http://en.wikipedia.org/wiki/Internet_protocol_suite#OSI_and_TCP.2FIP_layering_differences article that describes OSI and TCP/IP layering differences]. Routing happens in as many layers as are required by the definition of those layers, not only one. There are two layers that contain routing for XO-1, and one for XO-1.5, XO-1.75, and XO-4. The mesh on XO-1 automatically maintains a list of mesh nodes in the wireless module, considered to be physical routing. The other layer is TCP/IP routing, which is provided by Linux, and is not unique to OLPC XO, so it would be redundant to describe it here. Look for a text that describes TCP/IP. --[[User:Quozl|Quozl]] 01:32, 10 April 2013 (UTC) |

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 :-) |
|||
::::::::::Hello. I would like to know, is there anyway where the protocol parameters and be changed and analyzed? Thanks. |
|||
== Is the 'buy 2 and get 1' scheme going to happen? == |
|||
:::::::::::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) |

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. |

== Who has heard this OLPC "nerdcore" rap song? == |
|||
I think this whole idea of connecting receipient with donor and the distribution over ebay is a really fresh and clever idea of you. |
|||
The nerdcore rappers called "Dual Core" published a song about the OLPC on Jun 17, 2013. |
|||
: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. |

New questions
My OLPC stucked off after starting up and please also guide me that from where i can get new charger for my olpc?
Question
We are planning to help OPLC but we need to check the Financial Statements of the organization. Does somebody know where can we get this information?
- From OLPC directly, or the government or other regulators. I don't think you should rely on what contributors to a community Wiki might tell you ... that's not a rigorous method. --Quozl 03:23, 13 February 2012 (UTC)
Question
I turned on my OLPC but it didn't show anything.What do I do?
- Check out Keyboard freeze fix for os 650-656 it might be your problem. Hard to say, unless you can give some more information, like when you last used the XO, whether the power indicator turns on, whether the display backlight turns on. --Quozl 21:04, 30 August 2011 (UTC)
Question
how do download windows xp on to my olpc xo and how do you access your downloads
- There is no way to get Windows XP for your individual OLPC. Microsoft does not make it available to individuals, and OLPC has nothing to do with that.
Downloads
How to access your downloads?
- If you download things on the OLPC, they should show up in the Journal, which is one of the Activities that's always running. It looks like a little spiral notebook. You can also open the journal by pressing the "magnifying glass" icon in the upper-left hand part of the keyboard.
how do you start your downloads
I downloaded adobe flash player but i still can't watch my videos i know you go to journal and the file and click start but it doesn't work.
- See Adobe Flash for details. Mariano 06:44, 8 December 2009 (UTC)
your disk is full
What should i do if i go to my record activity and it says my disk is full?
- You should open your Journal and remove large files or activities. Mariano 06:44, 8 December 2009 (UTC)
== It seems that with the new built (8.2) in the XO the existing Scratch files are difficult to copy into a USB. I can't use the function "save as" or even copy them from the terminal. Any idea what to do? il me semble que mon "xo" est bloqué peut etre plein. que faire? Mamadou Niang mafabini@yahoo.fr je souhaite dans le cadre d'une ONG dénommée Bokk Diang avoir des partenaires pouvant permettre "d'arroser" les Ecoles Sénégalaises. merci de l'aide que vous nous apporterez. Mamadou Niang 00221776467585 Sénégal
How do I chat with other people in the world?
My xo is hooked up to the internet but I still don't know how to chat with other people in the world could you tell me how please?
- First connect to a Jabber server or your local school network. Then you can see other people on your network and will be able to chat with them.
- You can also download XoIRC and chat with people using that activity. 02:34, 17 December 2009 (UTC)
Downloads
How do I download music on my labtop?
- Click on a file to download. Then open it from your Journal. Alternately, install an activity like Jukebox.
How do I download Doom?
- The page about it is titled Doom. 02:34, 17 December 2009 (UTC)
Reset settings
I need to knnow how to reset the name on my xo laptop
- From the Sugar Control Panel, update your "About me" settings, and restart. 02:34, 17 December 2009 (UTC)
Viruses
How Do I erase viruses from my xo
i buy new usb to rs232 moduleboard ft232rl.and i conect my computer with my desktop but htere is nothing happnaed can some one tell me y or i conect it with other laptop not with desktop.i have olpc

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)
Server Installation detail Guide
Hi, I am am a new learner in this OLPC deployment team. I have installed a OLPC XS and had a problem with the eth0.

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.

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

Problem updating from 656 and mouse freeze
Hello I am having trouble updating from the 656 system and now my mouse and keyboard has frozen. Can you please advise me. Thank you. -- heather
- Hello Heather. What have you upgraded to? Does the mouse and keyboard remain frozen if you remove the power adapter and battery and put them back in? Write to help@laptop.org (our OLPC technical staff) if you'd prefer e-mail. --Quozl 02:01, 3 January 2011 (UTC)
- Hello
- I tried using the email but only got a generic response. To answer your questions:
- - I was trying to upgrade to the 10.1.2. I tried with the USB method and got the grey grid with a message underneath, something about NAND and size.
- - I then tried to update in terminal using all the various wordings proposed. That did not work either. I left the machine for a day or so and when I turned it back on the mouse and keyboard were frozen. When it lit up with the clock, it would go to a black screen with some text at about a quarter of the way round and then, before I could read it, it would go back to loading. I tried turning the machine on holding the O key which made the black text screen disappear but did not fix the freeze. I tried removing all power. I tried turning the machine on holding the rotate button. Nothing has worked yet. I'm really excited that you are responding to me and look forward to finding a solution.
- Take care. -- heather
- Did the generic mail response give you a tracking number? If so, let me know what it was. That will help us mark it as being handled.
- The grey grid sounds good, the message does not. There may be a fault in the laptop, or a problem with the download or preparation of the USB drive.
- The grey grid occurs with an install of 10.1.2, so I'm presuming you are wanting to do an install, which wipes all data off the laptop. If so, please try again and this time check that you are following the install instructions below and tell me exactly what the message about the NAND says.
- Regarding the update in terminal, I don't think you should try that again, because having started the install the contents of the internal storage is undefined, and the results may be unpredictable. The mouse and keyboard freeze is common; it happens if the laptop runs out of memory. We didn't test update from 656 and it may not work.
- Feel free to send me an e-mail at quozl@laptop.org if you like. --Quozl 22:24, 4 January 2011 (UTC)
How to install signed build os852 of release 10.1.2 on XO-1.
The build is installed to the internal NAND flash device. You will need a USB drive of at least 1 GB capacity, but only for the duration of the installation.
ALL USER DATA WILL BE ERASED FROM THE LAPTOP!
- Prepare the USB drive:
- Download os852.img,
- Save the file to the top directory of the USB drive,
- Download os852.img.fs.zip,
- Save the file to the top directory of the same USB drive,
- Rename the file to fs.zip, (removing the os852.img part of the name),
- Check the USB drive contains at least the two files fs.zip and os852.img.
- Prepare the laptop:
- Make a copy of any data you wish to keep,
- Check the battery is inserted and locked,
- Check that the power cord is in place and the battery indicator is green,
- Turn off the laptop, unless it is already off,
- Insert the USB drive into any USB port on the laptop,
- Start installing:
- Hold down all four game keys (see this in pictures),
- Turn on the laptop,
- Wait for the message Release the game keys to continue,
- Release the game keys.
Installation progress will be displayed. Green colour will fill yellow blocks. It will take about five minutes. Once finished, the laptop will reboot automatically. Remove the USB drive during or after the reboot. The USB drive can be used on other laptops.
If you see a message Boot failed then either:
- the USB drive has not been properly prepared, or;
- the firmware is out of date and should be updated (see Firmware).
Activities disappear
What to do if all of my activities disappear? Please Help!!!
- Reinstall might be a last resort. Someone else asked this recently, and it turned out that changing the language to one that isn't supported may cause this. Change it back. --Quozl 23:38, 1 February 2011 (UTC)

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

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!!!

una pequeña ayuda con una olpc
hola como estan
mi nombre es kevin molinares, soy de colombia y tengo un problema con una olpc xo-1. Resulta que soy tecnico en reparacion de computadores, entonces me dieron una olpc xo-1 para formatear windows, porque el sistema que traia le cayo muchos virus y estava muy lento, entonces yo formatee la SD de 4GB que trae pero no he podido hacer la instalacion de windows he intentado copiar una instalacion limpia que hice desde una maquina virtual pero no sirve la unica forma que logre iniciar es con un hirent boot CD. ahora si la pregunta ...
como hago o si necesito un driver, o donde bajo el windows xp para esta olpc xo-1 .. ya venia con windows xp de fabrica es mas tiene la licencia de windows original pegada debajo de la bateria, que tengo que hacer ?. le agradezco su respuesta que tengan un buen dia

Skype Video Calls & Broadband
I have 1.16 gb left of my broadband allowance this month. How long can I chat on skype using the video call facility?
turn on
my laptop turn on but then the screen stays black i have charged to full battery but it still does not do anything
downloading stuff
I want to download stuff on my XO laptop, but it keeps taking me to archive manager, which I don't like. I need instructions now!!!
- that is probably because you are downloading files that can only be opened by archive manager. exactly what files are you downloading? perhaps the files are not designed for your XO laptop. --Quozl 22:34, 11 October 2012 (UTC)
Technological and estructural diagram of the OLPC project
I am a volunteer at an organization that implements the OLPC project in Honduras. I am trying to help in different areas and one of them is to create documentation that will guide the end users of the program. This documentation is aided with descriptive images and one of them, which I need from you is the one that has the diagram of the structure of the OLPC project (technology oriented). I was looking at some links that show this diagram but I can not find it anymore. It has an oval of the acronym OLPC in the center and it branches out to the left with technology and to the right with outreach and education. It will be of great help if you can provide me with such an image.
Thank you,

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