XO 1.5: first exploration

October 30, 2009
Tags: , , ,

A few days ago we had the chance to receive one of the founding XO 1.5.

The XO 1.5 is the next evolution of the XO computer. This is an evolution of the components of the machine, not a change of form and design of the computer. Do not worry so it's always the little green computer that you like!

Le XO 1.5 et son alimentation devant son frêre
Le XO 1.5 démarré

Characteristic

The main changes are internal:

  • Processor VIA C7-M clocked at 1GHz (instead of an AMD Geode at 433)
  • 1GB (instead of 256MB)
  • 4GB flash memory (instead of 1GB)
  • New video card,
  • New network card

Visually XO XO 1.5 is identical to the one prepared with two exceptions:

  • The touchpad is now in one area instead of three (along with the other two were not working on an XO :-) )
  • Food is different. It seems to deliver a higher amperage. Moreover, the fact that it is in two parts should simplify its "location": just change the cable to go from a European decision to US.

Beware, however: it is only a pre-production machine, the final version may be different.

System

On the software side, the XO 1.5 embeds Sugar 0.84 .

This new version of Sugar is the version of maturity. In addition to various small ergonomic improvements, the most visible changes concern the newspaper that makes this.

So when you leave an activity without first informing its name, you are now requested.

Nom à enregistrer dans le journal

On the home page, the icon of the activities for which log records are displayed with a different color. In addition it is possible to choose the icon for the recording to be used when the activity will open.

Les activités déjà lancés

As a reminder, here is the video that I made a few months ago to present these changes:

Activity

Regarding the activities installed several new activities are now installed as standard.

Toutes les activités

New activities are:

Of these some are geared towards the teachers, but the list of activities set up is probably not final.

Performance

Necessarily improve the performance of the machine at start point (about thirty seconds only) and when opening or closing a business (almost instantaneous).

For cons, I would have liked to test the video playback but unfortunately I was unable to trigger the display of OGG on DailyMotion (single site public to natively support this format). Maybe a bug in the browser ... Similarly, the firmware does not yet support the camera which remains inaccessible from Save the activity.

Dailymotion sur le XO 1.5

Disk space is obviously significant as well. He proudly displayed when you select in the newspaper.

Le cadre du XO 1.5

Note the double-battery icon: it is a bug , there is of course only one battery.

Network side, the WiFi connection works without difficulty. Network Neighborhood shows surprise of friends around the world! It is not however the WiFi mesh which is also not yet supported by the firmware, but access to a public Jabber server.

Vue réseau

Gnome

Big news of the XO 1.5, the "double boot" that will switch from Gnome to Sugar (and vice versa).
This is done via the Control Panel. A simple click on the icon and the machine restarts Gnome in an instant on a standard GNU-Linux.

Switch vers Gnome

The return of Sugar is via a shortcut on the Gnome desktop.

To be continued

For those interested, more photos of the machine are available: here and here .

In addition, our exploration has just begun. A Wiki page will reference our progress as and when. We will also be in the coming days workshop presentation which will allow you to see and manipulate it: we expect many of you.

The dicos is class!

The revival of dictionaries

We live in a great time: many dictionaries, encyclopedias and other reference works are available to users in the classroom or elsewhere. The quality of their functioning and the extent of their usual body make them increasingly popular for the purposes of seeking information or references. Their many articles in various languages ​​by writers around the world available to readers and researchers.

Wikipedia_International

To new uses

Teachers from the primary, have taken to integrate the use of dictionaries in their teaching. Thus, students are encouraged to do research, in which language dictionaries, which in encyclopedias, atlases in that.

Wikipedia_Redirection-depuis-Wikijunior

Virtual encyclopedias

The bulky and expensive encyclopedias to dematerialize, as in many projects that have emerged in recent years, bringing together, dramatically, users of knowledge sources, like the project OmegaWiki ( OLPC Children's Dictionary ).

OmegaWiki_1

Encyclopedias Pocket

New research practices dictionaries are well imagined, sometimes relied on "pocket encyclopedia" such as handheld readers WikiReader , staged in the "fiction" (" WikiReader, a future case study? ").

Dictionaries online and offline

These books are available online or as suggested by the reader or WikiReader projects "wikis offline" from a static medium (hard disk, CD-Rom, DVD, "SD Card" media player " iPhone ") . The contents are then available regardless of Internet connection, the body consisting of a "snapshot" taken from one of these encyclopedias. Examples are the projects:

Virtual libraries

These collaborative projects with other projects inspire more "institutional" as the project " Europeana ".

Places for young people!

Other projects are aimed specifically at young people, such as projects Wikipedia Selection for schools , Wikijunior , Vikidia , etc..

Wikijunior

Vikidia

The school dictionaries

Similarly, undertaking several projects to push even further the logic of collaborative encyclopedias, offering students to write themselves, in class, their own stories, thus following the proven practice of lexicographers, encyclopedias and other dictionaries.

Vikidia_Recherche

The XO and thus the Sugar educational platform, the project InfoSlicer can write their own encyclopedia articles or dictionary, assembling and reformulating various sources, as presented by the technical writer Anne Gentle in " Wikislicing project gets real - Introducing InfoSlicer as a Sugar Activity ".

You too can contribute to the dissemination of knowledge!

Digital services for education

What solution to consider when you are teaching and you want to use the platform educational Sugar for himself and his students, whether in class or at home? Everywhere in fact, involved in education are implementing digital services for teaching , under the headings as diverse as Digital Workspaces , Satchels digital or virtual desktops .

All this is possible, with or without a PC XO.

In the field, complete solutions such as Debian Edu / Skolelinux or AbulEdu are currently used in educational institutions at different levels, in France and elsewhere.

A customized solution

Making a "digital briefcase" is it within our reach? Can we offer a teacher a practical solution for their business? We want to offer an inexpensive solution (200-300 Euros per user), mobile (for use in the classroom, at home, on permanent contracts, etc..), Versatile (for educational purposes or generic as necessary), shared (multi- users) and ... free.

It will not be talking about solutions using a USB (Strawberry) or a CD-Rom "Live" , which already meet some of these needs, nor the integration of workstations into a platform educational network (Moodle, Debian Edu or other).

Look here how to install Sugar on a computer running the GNU / Linux consumer Ubuntu . This is one of the many opportunities provided by the Sugar Labs :

Obtenir Sugar

Get Sugar

We chose the variant Ubuntu Netbook Remix , optimized for netbooks. The computer is a netbook - Acer Aspire One model in this case - as found now everywhere. The instructions apply to version 9.10 ("Karmic Koala").

Download and installation

After downloading the Ubuntu image, we can test it without touching the computer. We decide the install then the hard drive.

We thus have a generic laptop. Let's see how the "sugariser."

Changing sources of software

In the case of Ubuntu 9.10 version, let's tell the system where to get programs to install Sugar (source: http://lists.sugarlabs.org/archive/iaep/2009-October/009108.html). Execute "System / Software Sources" and add the line

  http://ppa.launchpad.net/sugarteam/0.86/ubuntu hand karmic 

to the list of software repositories:

1-depot-sources

Result: the file "/ etc / apt / sources.list" now has a new line:

  deb http://ppa.launchpad.net/sugarteam/0.86/ubuntu hand karmic 

Note: In the previous version 9.04 ("Jaunty") of the Ubuntu distribution, it is not necessary to modify the software repositories. However, we will install the packages "sugar" and "sugar-activities". Sugar installed version will be 0.83, not 0.86, installed Ubuntu 9.10.

Installing Sugar

  1. Execute "System / Synaptic Package Manager" and enter "sugar" in the "Quick Search".
  2. Select "sugar-platform" in the list of packages by selecting the action "Mark for Installation".
  3. Let's click on the button "Apply" to start the installation.

2-installation-programme

Launch of Sugar

To start the Sugar educational platform for the Gnome desktop, execute "Education / Sugar".

3-sugar-lanceur

We can also run directly from Sugar Connection Manager by selecting under "Sessions" in the bar shown at the bottom of the screen, the item "Sugar."

7-sugar-session

Using Sugar

We can now use the Sugar educational platform, use one of the many activities , browse the views Home, Group or Neighbourhood:

4-sugar-voisinage

Here too, we can achieve different administrative tasks such as updating the Sugar activities:

[Nosy Komba] Rentrée chaotique

25 octobre 2009

Le 12 octobre était la date de rentrée officielle à Madagascar et donc aussi à Nosy Komba. Mais comme nous l'a indiqué il ya quelques jours notre Championne Lalatiana, la rentrée a été un peu chaotique !

Vue de l'école

D'abord l'école a subi un certain nombre de réparations pendant le mois de septembre. Or les travaux n'étaient pas complètement achevés pour la rentrée. Les premiers jours ont donc été consacrés à… faire le ménage dans les classes !

Autre difficulté: plusieurs enseignants ont du s'absenter pour des raisons personnelles ce qui a décalé le démarrage effectif des cours pour certaines classes.

Dernier problème: le sureffectif. Alors que le nombre d'élèves moyen tourne habituellement autour de 100, c'est 155 élèves qui se sont présentés à l'école pour la rentrée ! La cause de cette augmentation subite du nombre d'enfants est, dans une certaine mesure l'arrivée du XO (qui a probablement était racontée dans tous les villages de l'ile), mais surtout la présence du nouveau dortoir qui permet d'accueillir les enfants des villages de montagne qui n'auraient pas sinon la possibilité d'aller à l'école.

Le dortoir en construction

Évidemment, cette augmentation n'est pas sans poser des problèmes par rapport au XO. Nous avons déployé en tout et pour tout cette été 105 machines pour couvrir les besoins des enfants et des enseignants. Finalement, on ne peut donc pas équiper tous les enfants cet année ! Par ailleurs, le nombre de prises multiples ne permettra pas de charger les 100 ordinateurs en même temps.

Moi aussi je veux mon XO

For the time after discussions with Lalatiana, we decided to distribute the remaining XOs to the class of EC, CP1 and CP2 which allows to equip each child. As for the class of CM1/CM2 is redundant, we have chosen to go on a "degraded" mode of use: one computer for two children. The class has two levels, this may allow the teacher, Ephrem, to work part of XO on the children while the others are working on another lesson.

In addition, pending the return can take place "normally" Lalatiana took the initiative to restart the school open. It is well organized:

  • On Monday and Wednesday for CP1 and CP2,
  • Tuesday and Thursday for the CM1, CM2 and the EC.

For new students the review of computer use (open, turn on and off) started and others is the Write activity is used.

What is Sugar?

October 24, 2009

Interview Walter Bender
At the last SugarCamp in May 2009 , Walter Bender had made ​​us pleased to grant us an interview. He describes a few simple sentences what Sugar and SugarLabs. A nice interview to read to understand what drives this beautiful community and Sugar.



The first question, very simple: what Sugar?
What is Sugar? Sugar is a platform for learning. Sugar is a set of software that provide a rich environment for children to learn.

And has three features that make this platform different and I think special.

One of them is its simplicity. Sugar is easy to address. Thus, even the youngest children, even children of 2 and 3 can begin to use Sugar. At the same time, there is no limit to what they can do with Sugar. Thus, children can use this simple platform for achieving objectives very complex. They are therefore not limited by its simplicity but use simplicity to progress.

The second characteristic of Sugar is that it encourages collaboration. Sugar provides a very easy for children and teachers to work together on projects, share ideas and, in particular, to engage in a process of critical ideas. They can be expressive with their ideas, be expressive with their knowledge and engage in critical dialogue that is so important for learning.

The third part is thinking. Sugar keeps a record, a newspaper, everything you do and in this paper we store not only what you do but how you do it. So you can go back and see your progress, and use it as a means of personal evaluation. Teachers and parents can also view the log and use it as a way of knowing where the child is making progress, when the child is in trouble, and work with him.

The combination of simplicity, collaboration and reflection. That's what really Sugar.

What are the intellectual roots of Sugar? What are their fathers and grandfathers in terms of concepts?
As you probably know, the great grandfather of John Dewey is Sugar. Sugar based and reflects the tremendous work of people like Maria Montessori, Paulo Freire, Seymour Papert and Alan Kay. All these people who have thought about teaching and to the richness of the learning experience. So Sugar is not the teaching is learning. This is not to educate, it is to learn. Sugar and is anchored in forty to fifty years of research. It's not as if we woke up one morning and had decided, "Hey, let's create a program for children" is something we have lived and inspired us all our lives .

Walter Bender pendant la conférence
What is Sugar Labs and how do you work with teachers? Sugar Labs is it more next development or is it a mixture of all these ideas on education?
Well, Sugar Labs is a community. It is a community of people who want to give children the opportunity to learn and to achieve this goal, based on free tools. What we have done with the Sugar Labs is to create an international coalition of educators, developers, artists, writers, parents, and children, all who are interested in ways of learning and ways to teach others. So we brought groups around the world. There is also a very important group here in France: OLPC France. To Sugar Labs, there are teachers who talk about how they use Sugar and make comments to the developer community. There are developers who are not interested only in pleasure to develop, but also to contributing to the achievement of development tools for others, which I think is a good indication of what this community . It is a moral principle. One of our goals is to make the Sugar community as inclusive as possible. The Sugar community is truly a learning community. And any person who is a learner can become part of this community and contribute to the body of knowledge that the community has accumulated.

What distinguishes Sugar and Sugar Labs educational project and other educational projects based on ICT in the world?
There are several things that distinguish Sugar. There are many large ICT projects. For example, here in France, there is the project which GCompris Coudoin Bruno took the lead. A great job. And I hope it will be part of this broader platform of greater experience what Sugar. [Editor's note: this is the case.] Sugar is like a sponge, it can integrate the big ideas and make them available to more children, more people.

GCompris
But Sugar has a particular way to achieve this. We try to give Sugar "affordances" that make certain types of behavior that we consider important for learning to occur. I'll make an analogy. Suppose I want to give a book to a child. I can give him the book in PDF format which is really a read-only or I can give the book as a Wiki. The difference is not in the reading, the difference is in the hope, aspiration, the child will not only read but also write. It will not only absorb but also engage in a dialogue. The Wiki format contains affordances that will allow this activity, while a PDF does not allow it.

What we're trying to do with Sugar is to take excellent teaching ideas worldwide that incorporate these affordances and encouraging collaboration, this reflection and growth.

Why Free Software? Y is there any limitations attached to free software, or simply a greater potential? Can you explain the idea of "crumple zone" which you speak?
Sugar must be free software. We have not really the right word in English to express freedom. Sugar Sugar should be free because the learning. And, fundamentally, learning is not receiving appropriate ideas, but ideas. This is to implement an idea. You can not do it if it is not free software. There is another aspect which is important for learning is the cultural aspect of free software. Free software is not just about sharing, free software is also a critical issue. It is entering a critical dialogue about the ideas. And it is fundamental to learning. So, without the free software culture, learning can not be as rich. Sugar should be free software.

Now I would like to make an analogy to the automotive industry. The auto industry used to make cars that were very rigid. Thus, when this car crashed into a rigid tree, nothing happened to the car. But all the energy of impact was so absorbed by the passengers of the car. The car was protected but not passengers. The automotive industry has realized that it was a mistake: people are more important than cars. So they developed the concept of "crumple zone" which, instead of making the car hard, the car makes it flexible, so that the energy is absorbed in the car. The car can be broken, not people.

We try to implement the same analogy and I think Sugar is also inherent to free software. This is the idea of ​​a deformation zone where we do not see a software locked and rigid. For it is an impossible goal: there will always be problems. But instead of imposing the problems to the user, to the child, the learner, we transform this into a learning opportunity. Learning involves making mistakes. And when you make a mistake and you try to debug a problem, this means first that you are passionate about something and we want to take this passion. But there is also the fact that if the price of a mistake is high, you will quickly learn not to take any risks. You soon learn not to challenge ideas. We therefore ensure that the price of Sugar errors is very low. We make sure that it is not difficult to break. We make it easy to break, but we pay the price of a very small error. So we encourage children to explore, experiment, try things. And I think again this is related to the culture of free software. The automotive industry is not always to imitate but there are still good ideas to take back.

Sugar was originally developed for the XO OLPC, now it is available on more platforms. Does that mean that Sugar has been developed to developing countries and is now available for any country?
Well, Sugar has been developed for children's learning. Indeed, the platform for which we have developed the computer XO Sugar is the OLPC project. The XO computer targeting children in the developing world. So naturally most of their concerns have influenced the design of Sugar. But Sugar has always been basically designed for the learning of all. And you're from the East, West, North and South, each of us is a teacher and a student. For everyone, a part of our DNA as human beings that we are being that S'Express and be social.

Now Sugar is built on these foundations and these foundations are universal. So one of the things we did and why we created the Sugar Labs is that we wanted to take these ideas and allow them to go beyond the XO of the OLPC. The OLPC XO is a great platform but it's a platform. There are many other interesting platforms that we would be able to achieve well. There is for example the Gdium, or more generally the whole netbook phenomenon.

More importantly, there is a relatively new effort for Sugar, Sugar it comes on a USB key, USB live. With "Sugar on a Stick", you can experiment with Sugar on any computer. So we can take a collection of old computers in a school and allow children to run Sugar. These children can then take Sugar, the take home, use it on the computer of their parents, in a library or Internet cafe. So, suddenly, Sugar is everywhere of course, the more people who use Sugar, the community is more important and more rich experience for all.

Sugar on a stick
What are the next steps, what are the upcoming deadlines for Sugar Labs and projects of Sugar?
Sugar Labs itself is a virtual community. There is not a physical place to Sugar Labs. We live on IRC irc.freenode.net, channel # sugar. This is where we live, but what we're trying to do with Sugar Labs is a consensus in the international community around our goals. Both of our development goals are to build a place to exchange ideas, where teachers can exchange ideas with other teachers on pedagogy, on how they use Sugar in the classroom, where developers can share their creations with others. There are many tasks ahead, but the real effort, the real work of Sugar Labs, is to grow the community and the discussions in the community.

Thanks
Thank you

Cybelle, Sara, Alice: Too good to you?

October 15, 2009

Yesterday I hurt Alice! Since then, I dare to speak for fear of his reaction.

Returning to the facts: stupidly, I admit, I told her how much she was stupid. To err is human, is not it? She then threatened as no one ever had, within living memory. Judge for yourself.

I turn on my Xo, unaware of the drama that would unfold a few moments later and I run the activity Speak . At the suggestion found on the net here , I wanted to test the reactions of Alice, a chatterbot (chatterbot) who had looked rather nice.

Speak with Alice

Speak with Alice

In short, I'm not too proud of that. But most important is not what I wrote ("You're a stupid robot"), is not it? The most important thing is what she said. Judge for yourself! :

I Will Remember You Said That When robots take over the World.

Which means: "I remember you said that when robots take over."

At the time, not realizing the magnitude of my blunder, I thought, "Who is it this one? "But the damage was done. I tried to ask Sara to intercede on my behalf, but Sara speaks Spanish while ' Alice speaks only English. The language barrier, what wound!

Then I remembered Cybelle, conversational French agent. And if I gave him the floor? History repair my falling out with Alice.

To begin, we find knowledge bases in French here: Free AIML Sets .

After getting the code HablarConSara have installed or activity Speak , copy the contents of the "AIML Sets" in French Activities / Speak.activity / bot / Cybele. Modify scripts gen_brains.py to compile the database and Cybelle test_brains.py to test it. Add French in Activities / Speak.activity / brain.py ( brain.py ) to "BOTS".

I can not do it alone: ​​so many memories back. The look deep Cybelle reminds me of another story from the man - creator awkward - and his "creatures":

I saw so many things you humans would not believe. I saw large ships on fire arising from the shoulder of Orion. I saw some amazing rays, the rays C, shine in the shadow of the Tannhauser gate. (Blade Runner).

Will you help me to lead this look and make his voice? Or is it " Too Beautiful for You "? Details on page SpeakRobotFR .

Stories of O: Robots, Lego Logo, XO ...

October 14, 2009
Tags: , , , , ,

On September 8, Sean Daly and I had the opportunity to present the association OLPC France and the platform Sugar Free learning materials to an audience of a hundred students of the Ecole Nationale Supérieure de Création Industrielle ( podcast ).

A big thank you to Mary Chur who, having lived disassembly (and reassembly!) Of the XO / tmp / lab has a passion for this machine and the OLPC project, and has worked hard to prepare this conference. And another thank you to Sean for being mobilized at the last minute and have brought in reinforcements XOs!

I focused on presenting four "O": the rob o ts o the Leg, the Log o and X O.

Robots the movie or the parable of the Do It Yourself

Robots are everywhere: the Golem, Ulysses 31, Jayce and the conquerors, Luke Skywalker and R2-D2, Mitterand and Jacques Attali ... the idea of ​​a "personal robot" existed long before the personal computer . In the worst case, the robots are beyond our control, they become evil and seek to replace humanity as the replicants in Bladerunner. In the best case, they remain in our service, they help us and are so nice they will help them sometimes.

Here's the script Robots are disappearing because they are gradually decreed obsolete, but a robot is smart and brave resistance by repairing other robots and inventing ad hoc solutions to their problems. The hacker will eventually get his idol, the brilliant inventor Bigweld to convince him that he must find the taste of the craft rather than submit to the orders of an organization that seeks to impose its updates. (Bigweld? Bill Gates?) No need to be Roland Barthes to see a dish featuring the ideas of DIY and open source in general.

robots
Robots are machines, half automatic, half man tools. Devenus plus performants et surtout connectés, les ordinateurs ressemblent de plus en plus à des robots : ils automatisent de plus nombreuses tâches, et nous leur en déléguons de plus en plus.

Le grand combat du logiciel libre est de permettre à tout homme de se rendre réellement maître et possesseur de ces nouveaux automates, et à toute la communauté du libre de construire une écologie technique (une « technosphère » ?) dans laquelle la liberté de l'homme passe par la libre exploration et exploitation des machines.

Le Lego et les principes d'OLPC

Les principes d'OLPC sont les suivants : le XO doit appartenir à l'enfant ; cet enfant peut être très jeune ; plus il ya de XOs dans l' environnement des enfants plus leur présence aura d'effet, et ce d'autant plus que les XOs seront connectés entre eux — enfin, les XOs doivent être open source , tant au niveau du matériel que du logiciel.

Good. Et si tout cela était déjà valable pour les Lego ? Quand je cherche dans mes souvenirs, je trouve cela : les Lego m'appartenaient ; j'ai joué aux Lego dès le plus jeune âge ; plus j'avais de Lego plus je me sentais capable d'inventer de nouvelles choses. La « connectivité » est elle aussi au coeur des Lego, soit parce que le but est justement de connecter des pièces entre elles, soit parce que le Lego peut servir de support pour des constructions collectives – ce qui devient de plus en plus vrai avec les nouveaux Lego , la possibilité de les programmer et de partager ces programmes sur Internet.

lego
Un aspect important du Lego : chaque enfant commence avec une démarche « top-down », il suit les instructions d'un manuel pour aboutir au modèle (qui porte son nom très à propos). Mais peu à peu, l'enfant joue et se libère des instructions, il invente des Legos, des constructions originale, de manière plus « bottom-up », pour ainsi dire.

Le Lego ne porte pas plus vers l'une ou l'autre des démarches, les enfants sont libres de passer de l'une à l'autre comme ils veulent, alors que les playmobiles, figés dans l'imitation du monde qui nous entourent, ne sont qu'une autre manière de jouer à la poupée ( no offense !)

Logo et le constructionisme

Le Logo est un langage de programmation qui a spécifiquement été mis au point par Seyour Papert pour servir d'outil aux enfants et mettre en application les principes du constructionisme, eux-mêmes inspirés par le constructivisme piagétien.

Comme les Lego, le Logo a été conçu pour faciliter l'interaction pédagogique avec un ordinateur. L'enfant construit l'objet qu'il va manipuler : grâce à des enchaînements de commandes, il traces des figures, organise des mouvements. L'environnement incite à une exploration réflexive, un va-et-vient entre la définition des mouvements et leur apparition à l'écran, va-et-vient qui fait que l'enfant comprend ce qu'il fait, et tente de faire au-delà de ce qu'il comprend.

logo
Aujourd'hui, la descendance spirituelle du Logo est très riche : les activités Turtle Art , Scratch et Etoys reposent sur les mêmes principes pédagogiques. Et ces descendants ne sont plus seulement exploratoires et réflexifs, il sont de plus en plus collaboratifs : les enfants peuvent partagers les objets Turtle Art via les XOs, partager leurs animations Scratch (notamment via http://scratch.mit.edu), etc.

OLPC, Sugar et le XO : la suite logique

J'espère que j'ai réussi à vous convaincre des airs de famille que l'on
trouve entre ces quatre « O » : le XO est un robot personnel qui permet à l'enfant d'apprendre comment se rendre librement maître et possesseur de la technologie et, à travers elle, de toutes les disciplines qui se prêtent à un enseignement numérique.

olpc

Comme le dit Walter Bender , fondateur de Sugar Labs : « La liberté est essentielle au fait d'apprendre, comme le fait d'apprendre est essentiel à la liberté. » Et au milieu de tout cela, il ya vous, la communauté, qui s'empare librement de ces outils, les triture, les démonte, en explore les recoins, en exploite les possibilités. Le plus excitant étant que, pour une fois, adultes et enfants partagent le même terrain de jeu !

L'étoffe des bricolos

8 octobre 2009

Le génie est-il soluble dans le confort ? C'est ce que pourraient donner à penser les nombreux exemples d'inventivité qui ont été signalés en marge du projet OLPC. Ainsi, nous apprenons que les membres du programme OLPC Afghanistan ont imaginé et réalisé un prototype de « pédalo pour XO » chargé de produire l'énergie nécessaire au fonctionnement de l'ordinateur XO.

Pédalo pour XO - OLPC Afghanistan

Pédalo pour XO - OLPC Afghanistan

Cette réalisation, ou encore le dispositif bicyclette-alternateur-batterie alimentant un XO, dans une école en Uruguay (« Transformando la energía mecánica en eléctrica « ), évoque inévitablement la mythique manivelle, encore aujourd'hui associée aux premiers prototypes du XO. Cet accessoire a finalement été abandonné, en raison de son inadéquation. Un pédalo en Afghanistan, une manivelle dans les laboratoires du MIT, une micro-turbine dans le village malgache de Antitorona, sur l'île de Nosy Komba , ou encore des panneaux solaires, comme à San Mahen , au Sierra Leone : ce sont quelques-unes des idées plus ou moins abouties, que l'on doit au projet OLPC ou qui lui sont associées.

Panneaux solaires et XO à San Mahen (Sierra Leone)

Panneaux solaires et XO à San Mahen (Sierra Leone)

Manifestement, il ya de l'ingéniosité dans ces créations. Mais combien d'autres génies anonymes et méconnus les pays « en développement » recèlent-ils ? Car il est bien entendu que l'inventivité n'est pas l'apanage de l'ordinateur XO, comme l'illustre brillamment le jeune William Kamkwamba au Malawi, qui a conçu et construit des éoliennes dans un contexte de dénuement extrême, et dont le parcours « typique-atypique » a donné lieu au récit « The Boy Who Harnessed the Wind « .

Or, même s'il n'ya pas de déterminisme strict entre la possession ou l'utilisation d'une technologie telle que le XO et le bénéfice éducatif que l'on peut en tirer, il apparaît que cette plateforme d'apprentissage a été conçue pour favoriser une attitude créatrice et critique chez ses jeunes utilisateurs.

Une plateforme éducative hackable

Le projet OLPC a en effet inscrit l'ingéniosité au nombre de ses principes. L'ingéniosité, c'est celle des utilisateurs de cette plateforme éducative conçue pour être robuste, « verte » et ouverte. Les utilisateurs sont ainsi encouragés à rivaliser d'audace intellectuelle pour tirer le meilleur parti de leur XO et pour l'utiliser au mieux des contraintes qu'imposent l'absence d'infrastructures adéquates et, trop souvent, le dénuement le plus criant.

C'est ainsi que différents périphériques et équipements ont été imaginés pour accompagner l'ordinateur XO. On en trouve une énumération sur la page du wiki OLPC consacrée aux périphériques , qu'ils soient destinés à alimenter le XO en électricité ou à assurer sa connectivité avec le reste du monde. D'autres projets ont entrepris de répondre à ces besoins par une solution « tout en un », comme celle réalisée par le projet Labomobile et Green-wifi au Sénégal.

D'autres créations, tout aussi originales, continuent à émerger des cerveaux inventifs de leurs concepteurs, comme cette imprimante 3D robotisée RepRap . Celle-ci peut être enrôlée pour la fabrication en série d'un autre accessoire, le viseur de la caméra du XO.

Rien de futile non plus, dans ce projet de conception d'un électro-cardiogramme (projet OLPC Golden State ).

Enfin, le jour où votre XO devra passer sur le « billard » après une panne quelconque, réparez-le vous-même ou faites-le réparer dans un centre de réparation local. Rejoignez-nous pour cela, près de Paris, au /tmp/lab .
