When you're looking at the XO laptop, do you think of it as a great platform for a modular content management system and blogging engine? I didn't think so. But Ian Ward and Eric Gundersen are not like you and I.

Drupal on the XO laptop

When I talked with Eric, I somehow encouraged him to think outside the box with One Laptop Per Child's clock-stopping hot technology and the result is Drupal on the XO:

Turns out that Drupal could be a flexible software application for the OLPC laptop. Three hours later (minus four hours spent hunting down a bug noted below) Drupal was up and running.

Right now, I'm viewing the Drupal site being served off the OLPC next to my desk from my MacBook via its private IP address. Wow, it's fast! The hardest part about the installation was the small keyboard.

Not only are Ian and Eric enthusiastic about all the applications that - once made lighter - students could get on their OLPC laptops, they even gave us the step-by-step tutorial for you to follow for your own Drupal XO CMS.

Now if I could only get an inspired Drupal developer to code me a new OLPC News...

Inside Constructivism

Constructivism gets its name from "Constructing Knowledge" in the students mind. Constructivism has its roots in Kant's synthesis of rationalism and empiricism, where it is noted that the subject has no direct access to external reality. The problem with pure theoretical Constructivism:

olpc Mongolia
Constructing and learning together
"Since constructivism rejects any direct verification of knowledge by comparing the constructed model with the outside world, its most important issue is how the subject can choose between different constructions to select the "right one".

Without such a selection criterion, constructivism would lapse into absolute relativism: the assumption that any model is as adequate as any other. The two most often used criteria are coherence, agreement between the different cognitive patterns within an individual's brain, and consensus, agreement between the different cognitive patterns of different individuals." Francis Heylighen

The flaws in theoretical Constructivism do not mean that it is worthless. It just has to be refashioned for use in real life. This would be the applied version of Constructivism. Once you infuse Constructivism with some realness, it has some valid points. To understand why the current schools don't work, you have to understand their origin...
"Schools were designed by Horace Mann and Barnard Sears and Harper of the University of Chicago and Thorndike of Columbia Teachers College and some other men to be instruments of the scientific management of a mass population. Schools are intended to produce through the application of formulae, formulaic human beings whose behavior can be predicted and controlled." - Gatto, NYC teacher of the year.
The one to focus on is Edward Lee Thorndike: His work on animal behavior and the learning process led to the theory of connectionism and helped lay the scientific foundation for modern educational psychology. Note that he worked on animals, and treated children as animals.

A theory called "law of effect": a principle of psychology described by Edward Thorndike. It holds that responses to stimuli that produce a satisfying or pleasant state of affairs in a particular situation are more likely to occur again in the situation. Conversely, responses that produce a discomforting, annoying or unpleasant effect are less likely to occur again in the situation. This is where we get the A = "good child" F= "bad child". There are two main problems:

  1. Student apathy and massive drop-out rate
  2. Thorndike's ideas, taken to their logical conclusion, takes you places that you really don't want to go; Orwellian totalitarianism.
The psychologist Abraham Maslow, in the early 1950's, gave education a new goal. The goal was for people to reach their full potential; this he called "Self-Actualization". A former student of Maslow's - Barbara Clark, an educator, noticed that students that were off the charts on the Benet tests (IQ tests) were failing in their classes. The reason was that the traditional education system was set up to "Program" people, and gifted children put up a mental block to stop it from affecting them.


OLPC Macedonia is something
Her solution was the first instance of Constructivism backed by the Government. The reasons she could do it were:
  1. Only 2% of the student body is gifted.
  2. It would be implemented within the framework of Special Education.
However, something is better than nothing. To advocate a head on challenge to the education system would have resulted in her being crushed by the prevailing education system.

Philosophy of cybernetics

AI is predicated on the presumption that knowledge is a commodity that can be stored inside of a machine, and that the application of such stored knowledge to the real world constitutes intelligence. Only within such a "realist" view of the world can, for example, semantic networks and rule-based expert systems appear to be a route to intelligent machines.

Cybernetics in contrast has evolved from a "constructivist" view of the world where objectivity derives from shared agreement about meaning, and where information (or intelligence for that matter) is an attribute of an interaction rather than a commodity stored in a computer. These differences are not merely semantic in character, but rather determine fundamentally the source and direction of research performed from a cybernetic, versus an AI, stance.

Limits to knowing

In working to derive functional models common to all systems, early cybernetic researchers quickly realized that their "science of observed systems" cannot be divorced from "a science of observing systems" - because it is we who observes.

The cybernetic approach is centrally concerned with this unavoidable limitation of what we can know: our own subjectivity. In this way cybernetics is aptly called "applied epistemology". At minimum, its utility is the production of useful descriptions, and, specifically, descriptions that include the observer in the description.


Ivan: steering education

Origins of "cybernetics"

The term itself began its rise to popularity in 1947 when Norbert Wiener used it to name a discipline apart from, but touching upon, such established disciplines as electrical engineering, mathematics, biology, neurophysiology, anthropology, and psychology. Wiener needed a name for their new discipline, and they adapted a Greek word meaning "the art of steering" (the term "governor" derives from the same root).

OLPC's descendence from Special Educational

There have been programs that have implemented the cybernetics and construction combination. It has evolved far beyond the more obvious combinations.

  • Biofeedback centered learning (Barbara Clark) students learning with computerized biofeedback
  • Visual Spatial learning (Alexandra Golon) students learn via computer graphics
  • Brain based learning (Linda Williams) students with computerized brain activity monitoring
It should be noted that most people are not aware of such programs due to the deals made between Clark, the Teachers Unions, and the Department of Education. It was this Clark doctrine that alternative forms of education would be tolerated and allowed to exist only if it was agreed to stay within the confines of special education.

Thus, it would be unfair to consider that such alternatives "just didn't catch on". It ignores the reality that such researchers and programs had to remain under the radar.

The OLPC project would be first time such teaching methods and the fruits of decades of researcher would be made available to a large population...any large population. They are not new or experimental, but rather suppressed.

Mary Lou Jepsen of OLPC

If there's a trend that is universally welcome is the greener technology trend. But in most industries green is sold at a special premium: from organic food to electric cars, you are paying for your eco-conscience. But Mary Lou Jepsen has different approach.

At first when told that to go green would be more costly the OLPC was willing to sacrifice a greener XO for a cheaper but not so green laptop. But as she progressed on the design process it became clear that to build a laptop that cost less also means a laptop that consumes less resources as a whole. In her words:

"People are trying to make a buck off of green. Green is actually cheaper. Green isn't about (sigh) buying more stuff."
According to a very inspiring keynote she gave at the Greener Gadget conference in the beginning of February the factors of making a laptop green are:
  • Consume less power. According to Mary Lou if every computer in the consumer market had the power footprint of the XO, their total energy consumption could fall 95%. Also by reducing the necessary power it needs to run you put the laptop under the threshold that can be provided by some clever and surprisingly low tech sources, as cows, bicycles or cheap solar panels.
  • Expand the lifetime of the product. Surprisingly enough that's a factor rarely factored in when figuring out the impact of a product: how long will it last?
  • Repairing is more important than recycling. If disposed the XO battery can be "consumed by soil bacteria" but Mary Lou has a bigger point: by making the laptop easier to service will prevent it from being dumped in the first place.
You can check the highlights of the presentation above, but I would highly recommend anyone actually watching the whole 50 minutes presentation where she talks a bit about the purpose of her new company PixelQi, the deployment of the laptop and the history of the design.

Or if you attended you could have done as Crackhead did and actually get Jepsen to sign your XO.

Linton + XO in low-stress mode
The OLPC has great potential for use in humanitarian assistance and disaster relief situations. The machine's portability, mesh networking capabilities, file sharing potential, robustness and the ability to read the screen in broad daylight could be great advantages in stressed environments where communications are interrupted, organizations are being improvised and electrical power could be intermittent.

Think the stressed environments of post-tsunami, earthquake, or hurricane.

I only have my own OLPC, but would love to test out the mesh networking and ad hoc coordination potential with other XO users. It would be great if we could show mesh connectivity among several OLPCs, and perhaps experiment with disaster relief scenarios.

I'll be in Miami from March 10-13 and I would be interested in hearing from anyone who has an OLPC in the Miami area, particularly those who could bring it to the National Defense Industrial Association logistics conference at the Hyatt Regency Miami (400 SE Second Street) between about 8 and 4 on those dates.

Did you know that the One Laptop Per Child computer has a little magnet on the bottom left side of the keyboard?

There to activate a sensor in the display area above the microphone when the XO is closed, the magnet tells the XO when to go into a power-saving mode, but I don't think the software is released yet.

You can still have fun with the magnet, even if it's not fully functional. I like to use it as a cool party trick with a USB memory key:
What do you use your XO magnet for?

Monitoring Morse Code with XO
Long before the advent of the personal computer, ham radio operators communicated keyboard to keyboard. As early as the 1950s, Ham's used modes such as Radio Teletype using 5 bit code. Perhaps slow under current conditions, 45.45 baud (about 60 words per minute) is certainly fast enough for chat!

Plowing deeper we discover that hams were some of the first adopters of digital communications. Ever heard of Morse code? Quantized coding of the alphabet certainly qualifies as digital!

During the first part of the last century, Hams were the ubergeeks. Through the work of a few devoted Hams and XO geeks, digital keyboard modes are available on the XO!

Fldigi is a multi-mode program that has been "sugarized" for the XO. It can be integrated with a radio for Ham radio applications or can be used with the built-in speaker and mic sending data across a room via audio. It is a great way to demonstrate theories of digital signals and audio properties in a classroom setting.

Indian kids ♥ XO laptops
I saw the Waveplace Foundation call for help getting some more donated XO laptops for their project in Haiti and thought of our own project.

We are a Belgian NGO, Anthony Charity, and we have a school project in a remote place in north India. Nobody cares about educating the children in the villages in India, that is why we are there. We have 525 students already and we get 125 more each year.

The school is called "St-Anthony School". We cannot afford to invest in 100 XO (the minimum number proposed by OLPC). That is why, recently we purchased some XO on Ebay (nine). Five have already reached the school as you can see on the pictures, the remaining ones will reach next week. We have an address in the USA in Florida where we collect the laptops, they are sent together in one package from there to India with DHL.

Tomorrow's meeting of the OLPC Learning Club-DC has had a last-minute location change which brings us to the regional office of Nortel Networks, one of the original investors in OLPC.

Nortel LearnIT, a community relations initiative of Nortel Networks, has kindly offered the use of an OLPC Active Antenna which will make possible the setting up of a mesh networked school server environment.

A team from Arlington County Public Schools (in Virginia) is setting up the OLPC school server and coordinating with the OLPC support gang to help install system updates, activate developer’s keys on anyone’s XO and generally troubleshoot technical issues.

The meeting will start with a few minutes of introductions by the leaders of the table activities. Then we will break into groups for about 30 minutes for discussion. We’ll pause for quick reportouts from each group on tips, discoveries, aspirations, frustrations, etc. Then we’ll all mesh some more until 1 pm.

My brother Joe Felsentein, who is famous in the world of population genetics, tells how for decades those working in his corner of biology (phylogenetic inference – the science of constructing inheritance trees) were scorned by the reigning molecular biologists as "stamp collectors".

While the molecular biologists pursued the secret of life itself, the stamp collectors puttered around with statistics and large data sets, working out how to make sense out of data patterns.

Then came the crowning triumph of molecular biology – reading the human genome. Note that I do not say "decoding the human genome", as it suddenly became clear that no one knew how to make sense of gigabytes of gene sequence data. Who, the moleculars wondered, could make some order of all this data?

Then everyone looked at each other and exclaimed in unison, "the stamp collectors!" Joe and his colleagues were showered with money and attention. Their grant requests were now favored for approval, and at Joe's university a brand-new Department of Genome Sciences was created which welcomed his august presence.

The parallel is this – the OLPC project is about as far as it can go without empowering its own "stamp collectors", by which I mean those who have long labored in the field of experimental education. Yes, there are others besides Seymour Papert, and the official OLPC line on the topic, that the educational research had already been done and that the engineering was all that was left, was always blatantly untrue.

Liam XO mesh networking


My six-year-old son, Liam, and I recently attended a One Laptop Per Child networking event at the Marie Murphy school in Wilmette, IL. The event was put on by Chris Brown as part of a teacher professional development day. He invited area XO owners to come talk about our computers as well as have the opportunity to network with others in the community. One blogged about it here.

About 10-15 laptops were present at peak. We gathered around a large conference table in the resource room and quickly got to work. Liam was beyond excited to have so many “friends” show up on his neighborhood view.

We quickly “friended” everyone (by hovering on their icons and selecting “add as friend”) we could from the neighborhood view, then looked at the Group view to see all the colorful XOs on our screens. Shh, don’t tell Anastasia I had her laptop out while she was at school.

If imitation is the sincerest form of flattery, Elonex is about to change its name to "Laptop Per Child" to complete its total imitation of OLPC. This unknown UK-based computer assembly company has done pretty much everything else to be like One Laptop Per Child.
olpc elonex
Let's recount the displays of imitation flattery, eh?
  1. They're claiming to have a £100 laptop for the United Kingdom, which sounds exactly like the "$100 laptop" claim of OLPC, regardless of the currency difference.
  2. They came out with a ugly marketing image long before they have a real laptop, kinda of like OLPC's green hand-crank laptop.
  3. They're focused on educational sales to government, this time in the UK.
  4. They called it the "One Laptop" which copies OLPC's name a little to close for comfort
  5. The president of Elonex is legally changing his name to "Nicholas Negroponte"
Okay, so I made the last one up, but would you really be surprised if that was their next step? The OLPC-mimic has gone too far with this XO-wanna be.

No matter what Elonex announces at the Education Show 2008, don't forget: You know OLPC. You've followed them before they were known. Elonex is no OLPC. Its not even Aware.

Would this keyboard help?
I'm physically disabled and type with a stick in my mouth. The OLPC is my first and only experience with Linux.

I did find and successfully complete simple instructions on changing nickname on my OLPC. In doing so, somebody had to hold the shift key for the quotes. How can I set up OLPC for one finger typing as in Windows? I need to be able to hit Ctrl+Alt+Erase one key at a time.

If you have any simple instructions for this elderly physically challenged wanna be geek, I will be eternally grateful. At my age I try and stick with the KISS rule... no insult intended. Thank you.
Thanks need to go out to Eden, Moocapiean, and LesleyT, as all three rose to the challenge and are activity searching for a solution to Tacotaxi's need for one finger typing.

Eden and Moocapiean are working the the software angle - they started with the OLPC Wiki on Accessibility and are now testing different solutions to give tacotaxi a one-step solution: AccessX. LesleyT is taking a different, more physical angle

Motion detection spy cam
Let's say you have an XO laptop from One Laptop Per Child. And you want to record events in your surrounding environment. Activity that may occur when you're not around. How could you make the XO laptop a remote sensing device?

First we have an interesting hack by Edward Robinson that turns the X0 laptop into a spy camera:
After jumping onto the #OLPC freenode irc room and asking them a few questions I was quickly able to write this python program.Set it up as a cron job and upload pictures from outside my apartment window every hour.
But what if you want your XO Spy Cam to be motion activated, not time lapse photography? Then you need to use the motion detection settings by Quozl.

Its Khawaji again, and I just returned from a trip to rural Sudan with an XO laptop and I'd like to share my experience.

Baby Steps

The XO as an educational tool has so much potential, and puts such a vast horizon before children that one can't help but be excited, but the difficulty in realizing that potential lies in the first step.

How do children who have never seen anything remotely like a computer (in the case of these children probably not even a cell phone) react to this sort of thing? I was able to test that out briefly as I was in a very rural area last week, and was delighted to see that they took to it immediately.

There was a bit of impatience with the slow boot time, but within 15 minutes I could get them to record songs and videos of themselves. In this video, Abd ar-Raziq explains the process of how his family grows tobacco:
I also got them started typing a little bit with the word program (somewhat difficult since I don't have an Arabic XO - though it looks like the pootle translations for Arabic are done... anyone know how to install it?). After about a half an hour though, I was really scratching my head for something that they could pick up quickly and see the results of.

olpc $100 laptop
Non-profits are, in law, permitted to make a profit, though few do. The legal restriction is simply that profits may not be distributed to investors, so a non-profit doesn't have shareholders. Why might a non-profit want to profit?

Well, of course, most don't. In particular, Nicholas Negroponte is determined not to make a profit on the OLPC XO laptop, which some will see as entirely laudable. I don't, as I will explain.

No Profit Impacts

Now, it's true, OLPC charges governments $1 over cost, and the Give One Get One program charges $199.50 each for two XOs that cost $178 or so at the factory. That's not what industry considers a profit margin, since it doesn't even cover basic expenses like customer support, and that's where my argument begins.

G1G1 customer support is abysmal.
  • Misaddressed packages due to faulty software design in the fulfillment system. (If you entered Company Name and Street Address on separate lines, the second got dropped, and the shipping company sent it back. The workaround was to abbreviate the company name and squeeze both into one line.)
  • Customers whose XOs came back were not notified.
  • No responses to e-mails.
  • Spending 45 minutes on hold to talk to a person.
  • Taking more than a month to figure out how to ship to Canada.
All of this is done in the name of sending everything possible to poor schoolchildren, as the name Give One Get One makes abundantly clear. Certainly it is an important measure of conventional non-profit performance to look at how much money goes to the people to be helped, and how much goes to office expense, salaries, raising more money, etc.

But OLPC isn't a conventional non-profit, and shouldn't think of itself that way, IMNSHO (In My Not-So-Humble Opinion).

Where to Spend Profits

Now I'm not suggesting that OLPC simply go corporate. One of the reasons why the XO is less expensive than the alternatives is that OLPC is a non-profit, and many of the people there, including Nicholas Negroponte himself, work as volunteers. As do I (although I have applied for a paid position).

Hacking the XO form factor
Have you experienced the "sticky keyboard" issues that plagued the G1G1 XO laptops from OLPC? Did you RMA your laptop and then wait with bated breath for a replacement XO to appear on your door?

Fools! You should have gone Constructionist learning like a 5-year old girl in Nigeria and built your own XO laptop hospital . Or you could be cool like Jacob Rose and upgrade your keyboard with a random USB keyboard.

Jacob was frustrated by his X0's keyboard issues and dreamed of a normal keycaps-and-springs type USB keyboard. Yet unlike me, he was not afraid of radical surgery to achieve his dream of squeezing a new keyboard into the lower half of the X0 case:
Radical surgery to the lower half of the XO is necessary, so your OLPC will never be the same if you do this. I did it because I had too many Dremel wheels on my hands and my XO was so much more convenient to cut holes in than my neighbor's car.

XO laptops for Irving, Texas
I am Sam Farsaii, Director, Instructional Technology, in Irving Independent School District, Texas.

I've been eagerly following-up on the $100 laptop project for more than two years, so it is no surprise that I got my XO laptop just before Christmas!! What a treat for the first day buyers.

I think XO is a marvelous achievement thanks to all the genius behind the project. This is truly a revolutionary idea to help CHANGE education inside-out, and that is not an easy task. I think this constructivist learning tool is the catalysts in shifting learning from teacher centered to student centered environment and Seymour Papert’s dream is slowly coming true.

Now the challenge is to work with our teachers to believe in the same by teaching them to help kids create new knowledge rather than just memorize trivial facts with focus on information literacy, learning to be global citizens, learn how to learn, and think critically.
