Uruguay reacts to Plan Ceibal book pre-launch

Roberto Balaguer notes that a book we are collaborating on has captured the attention of the president of Uruguay:

The website of the Presidency of the Republic [of Uruguay] takes the news. On Tuesday, in connection with the [Montevideo International] Book Fair, we held the pre-presentation of the book on Ceibal Plan and the OLPC model, collective work and shared invaluable colleagues in Argentina, Mexico, Spain, USA, and, of course, Uruguay.

Plan Ceibal

Uruguay, through the Ceibal Plan, was the first country to adopt the One Laptop Per Child platform. Roberto Balaguer compiled an international, critical look into the initiative, that provides an extensive review. The following collaborators contributed to the volume:

1. Roberto Balaguer (Uruguay) “Plan Ceibal: Los ojos del mundo en el primer modelo OLPC a escala nacional” [“Plan Ceibal: The eyes of the world in the first OLPC nationwide model”].
2. Fernando Garrido (Spain) “¿Otra vez el mismo error? OLPC, Determinismo Tecnológico y Educación” [“Again the same mistake? OLPC technological determinism and education”].
3. Edgar Gómez Cruz (Mexico) “Domesticación de la Tecnología: una aproximación crítica al proyecto de OLPC” [“Domestication of technology: A critical approach to the OLPC project”].
4. Tíscar Lara (Spain) “Aprender a ser ciudadano desde las prácticas digitales” [“Learning to be a citizen from digital practices”].
5. Guillermo Lutzky (Argentina) “La Escuela Digital, un cambio obligatorio para los modelos 1 a 1” [“The Digital School, a change required to 1 to 1 models”].
6. Mónica BaezGraciela Rabajoli (Uruguay) “La escuela extendida. Impacto del Modelo CEIBAL” [“The school extended: Impact of the Ceibal model”].
7. Alicia Kachinovsky (Uruguay) “La Universidad de la República en tiempos del Plan Ceibal” [“The University of the Republic in times of the Ceibal Plan”].
8. Octavio Islas (Mexico) “Retos que representa la enseñanza en el imaginario de la ‘Generación Einstein'” [“Challenges posed by teaching in the imagination of the ‘Einstein Generation'”].
9. Cristóbal Cobo (Mexico) “Aprendizaje de código abierto” [“Learning from open source”].
10. Raúl Trejo Delarbre (Mexico) “Un niño para cada laptop” [“A laptop for every child”].
11. John Moravec (USA) “¿Y ahora, qué?” [“So, what now?”].
12. Miguel Brechner (Uruguay) “Los tres si” [“The three yeses”].

I join many of the collaborators in dedicating my contribution to the volume to our colleague and co-author, Guillermo Lutzky, who passed away late last month.

One probabilistic computer per child


OLPC may see a new competitor enter the market. Utilizing a new microprocessor technology that embraces probabilistic logic computing rather than traditional boolean logic computing, a team at Rice University is designing a digital, touchscreen, LED slate for deployment in developing countries. Probabilistic computing permits devices to provide correct answers most of the time rather than all of the time, allowing for dramatic reductions in power consumption while speeding-up computations considerably. The reduced chip-based power consumption will allow the device to powered by solar cells.

From Popular Mechanics:

What it is: The “I-Slate,” a solar-powered, stylus-controlled classroom aid unveiled at the IEEE’s 125th Anniversary event on Tuesday. The idea is that this LED slate will replace the chalk slates still used in much of the world, allowing students to learn basic math skills without the need for a literate teacher (something that is in demand in much of the world). The device is being created by Dr. Krishna Palem and his team at Rice University.


The slate will be able to download coursework using wireless networks. And because these chips should be far cheaper to produce than the high-powered processors found in most new products, making them practical for the third world.

From Rice University’s news release:

Inspired by microfinance, the I-slate’s innovators intend to use social entrepreneurism to create a self-sustaining economic model for the I-slate that both creates jobs in impoverished areas and ensures the I-slate’s continued success regardless of ongoing philanthropic support.

The first prototype PCMOS chips were found to use 30 times less electricity while running seven times faster than today’s best technology. Palem’s PCMOS team includes researchers at Rice and at the Institute for Sustainable Nanoelectronics at Nanyang Technological University in Singapore, where the first PCMOS prototypes were manufactured last year.

India's $10 laptop to be unveiled soon

10 dollars

Feb 4 2009 Update: Found at Technology Review: “It turns out that India’s ‘$20 laptop’ — a gadget meant to cheaply deliver online educational content to students at more than 18,000 Indian colleges — may actually be more of a handheld web access device than a laptop computer.” And, it doesn’t look like a laptop at all. What is it, really?


This is just a quick note on an item spotted at

( — On February 3, the Indian government will display a prototype of the Rs 500, a $10 laptop that will hopefully give more young people the opportunity to learn and help increase the country’s school enrollment.


The $10 laptop will be equipped with 2 GB of memory, WiFi, fixed Ethernet, expandable memory, and consume just 2 watts of power.

Pre-mass production, the cost of the laptop is down to $20 per unit, which is dramatically lower than the $47/unit manufacturing cost noted by Education Futures in 2007. We will follow this closely over the next few months as production and distribution of the devices take off.
