One Laptop per Child

Rwanda’s next 100,000 laptops arrive this month

Rwanda will have 200,000 children using XOs by the end of the year. They are putting the second phase of their deployment into place over the next few months, in time for the second term this year. The laptops will start to be delivered later this month.

Each participating public school – at least one per sector – will have a school server installed with mathematics, science and English software to enable teachers to teach using laptops. Two teachers at each school are taught to handle troubleshooting hardware and software. Schools with no access to electricity will continue to be connected to solar energy.

The program has been particularly popular among parents of children receiving the laptops. And private schools and individuals can buy laptops for $200 apiece.

Nkubito Bakuramutsa, the head of the initiative, said of the new schools joining the program: “I call upon parents and teachers to support the OLPC project. I am optimistic that the beneficiaries will compete favourably on the labour market after completing their studies.”

Professor Sugata Mitra, champion of the concept of “minimally invasive education” (MIE), will discuss the question “Is Education Obsolete?” Mitra has most recently been collaborating with Nicholas Negroponte to test a deployment of 20 Android tablets in a remote village in Ethiopia. The talk will be webcast live and archived here: http://j.mp/JJ6fQr

5-day Preview of Scratch 2.0 – The Scratch team at the MIT Media Lab has been hard at work developing the next generation of Scratch, which will be completely web-based, requiring no installation of software. To commemorate Scratch Day and the 5th anniversary of the software, the team will open up the alpha version of the new site starting this Thursday May 17 through Monday May 21. The site is currently password protected, but check this link soon: http://alpha.scratch.mit.edu/ Here’s a preview video: http://vimeo.com/41683547

Get Your MaKey MaKey! – Two graduating members of the Scratch team, Eric Rosenbaum and Jay Silver, have revealed a new project on Kickstarter called MaKey MaKey. It’s an amazing little $35 circuit board that turns almost any real-word object into a computer keyboard or piano key input. It requires no assembly or additional software other than what you have already to create a piano out of bananas or a game controller made of Playdoh or buckets of water to name a few of the infinite possibilities. The project was fully funded last night after launching early on Monday. Hurry over to the site to learn more and place an order: http://makeymakey.com/

O’Reilly Books 50% Off 18 E-books This Weekend – It turns out this weekend is also when Maker Faire will be held in San Mateo, California. To celebrate, O’Reilly is discounting by 50% selected DRM-free ebooks on the topics of robots, sensors and science. Visit this link: http://j.mp/Klh5ys

Well thanks for sticking with this long message. I hope there’s something for everyone whether you can attend Scratch Day or not. See you soon!

Learning to read with One Tablet per Child

Can tablets make a difference to a child learning to read for the first time, without a teacher or traditional classroom structure? That’s the question we are exploring with our reading project, currently underway in Ethiopia.


A few dozen children in two rural villages have been given tablets which they are using for a few months. They are interested in learning to read English, and understand this is something they can learn with the tablets; which also come with hundreds of children’s apps.

They are equipped with software that logs all interactions, building up a clear picture of how each tablet is being used. Data from the tablets is gathered each week and sent back to the research team, which also rolls out new updates to the tablets week by week.

Richard is in Ethiopia this week, to get better first-hand knowledge of how the tablets and other infrastructure are holding up, and a visual sense of how they are being used.

“if a child can learn to read, they can read to learn”

Achievement in Attawapiskat

Attawapiskat has become one of the best known northern Ontario communities, due to extensive coverage of social and economic challenges. Dust has since replaced the snow, the cameras have gone, and a community remains.

It is difficult to describe the feeling of this place. Local student poetry speaks for itself:

Attawapiskat

Fun, Small

Hunting, Jogging, Visiting

I like bike riding

Home

 

Attawapiskat

Fun, Cool

Playing, Hunting, Running

I like going hunting

Home

 

Town

People, Houses

Talking, Honking, Barking

I live in Attawapiskat

Attawapiskat

It is easy to meet kind, welcoming people in Attawapiskat – the kind of people who make a point to remember your name. Word spreads when visitors arrive and children greet newcomers with “I know you, I’ve seen you around. What’s your name? Where are you from. Do you speak Cree?”

While facilitating lessons with the primary and junior grades I was taken aback by the level of literacy and student concentration in class. Grade 2 students were challenged to create a game with their spelling words. 6 words were placed on the board and before we could visit each laptop to offer support, the children were asking for more. Students got through an incredible number of words before the class was finished and created some wonderful games.

The experience of on-task, attentive, enthusiastic student work was consistent throughout the many portables that make up the J.R. Nakogee School (the school building was demolished due to contamination over a decade ago).

Vice Principal Wayne suggests that gains in literacy and academic performance can be traced to the school’s literacy program lead by Principal Stella. Literacy coaches have worked with students and teachers to develop learning strategies for each grade level. Student progress is measured at various points throughout the year and this information is tracked on a board in the Principal’s office. At a glance Stella can assess where students and entire classrooms are at and where enhanced attention may be required.

Throughout the visit Administrators, Teachers and Teaching Assistants expressed interest in utilizing the laptop as a tool. A meeting was held on Thursday afternoon to highlight strategies for laptop use in the classroom, and staff came prepared with their laptops and tried new activities throughout the meeting.

Student Work

This week students utilized their laptops to engage with various subjects this week at J.R. Nakogee.

Victoria’s Grade 3 class documented and imagined the life of insects. First we headed to the playground to capture close up landscape images with our laptops.

Next, students imaged the type of bug that might inhabit this landscape and how they might perceive it. Students imported their photographs into Paint and added insects from their imaginations.

Students began to draft stories about their creations by importing their drawing into Write. Rather than sticking to traditional landscapes, students were quite creative with where bugs might be found…

Students in various classes chose to make Ecards for Mother’s Day:

Of course it wouldn’t be Mother’s Day without flowers!

Students of Jane’s Grade 3 class experimented with Physics, using forces to bring their drawings to life:

Grade 8 students put their knowledge of History to use, creating a matching game about Confederation:

It is a privilege to visit a community like Attawapiskat. Thank you to everyone who participated this visit and offered a greeting in town. This community is so much more than television cameras and news reports could ever capture…

Thank you to photographer Adam Biehler who was kind enough to capture our work with the Grade 3s! http://www.adambiehler.com/

On Kindles and the importance of fixable machines

Kyle Wiens of the Fixers project is tracking how electronics and other gear is used and fixed across Africa — and which things are destined to be landfill. He writes in the Atlantic this month about the challenges of maintaining computers in rural schools.

He looks at a popular Kindle-as-bookreader program, noting how predictable their high levels of breakage were, and how useful it would have been to be able to repair them in the field.

He cites OLPC’s design, public repair guides, and comprehensive list of parts as models for others to follow. And he kindly offers to help projects like Worldreader and others write a good repair manual if they would only do so and ship it with their devices. Take him up on that — he writes well!

Pro Bono or No No?

My cousin sent me a call for help from a friend of hers that said the following...

"wishes filmmakers and programmers worked pro bono for amazing causes. I have an amazing cause that needs this type of talent! If you know anyone who wants to do good in the world and will film things, edit things, or make computery things for free (even in bits and pieces) send them my way .... We can have student interns do the programming *or* the video, but not both... I just wish the grant we were working on could pay for what we need done."

So, some thoughts.  Yes there are solutions but first something about the "pro bono" thing.  That's a term that comes from lawyer-land, where the salaries are generally six figures, low to hi.  Independent filmmakers generally make four figures, low to hi :-)  They a are generally passionate people who have their own interests they went into filmmaking for and they are almost always asked to donate their time to worthy causes, which they would love to support if they didn't have that pesky need to eat. 

Programmers are generally either full time employed, in which case they may be making lawyer $ but working 60-80 hours a week.  Or they are unemployed or indies and then see the reference to independent filmmakers above :-)

Of course there are always exceptions to the statements above and I hope that people find those selfless volunteers.  If not, there are the following options.

1.  Class/thesis projects.  Student projects that are funded in credits, not $.  Especially in a university environment, as this writer is, these are options that often serve.

2.  Barter.  The program this writer wants documented/supported is theraputic in nature.  Perhaps some trade of therapy hours for filming or programming might be an option.

3.  Crowd-Sourced Funding.  Kickstarter is the 800 lb gorilla at the moment, but there are others
http://dowser.org/top-ten-crowdsourced-funding-platforms/.  Find programmers/filmmakers, spec the costs of the projects, make a pitch and see what develops.  Reaching out to professionals to work together to get a project funded (much faster and with much less pain than by writing a grant) is something that will likely be better received and allow you to find a more dedicated and more professional partner.

Sol Computer to sell a Pixel Qi-enabled netbook and tablet for $1K

Sol Computer, a California-based distributor that focuses on sunlight-readable technology, has a high-end line of rugged netbook laptops, is planning to sell a similar tablet for $950 later this year. It looks a lot like they are targeting an OLPC use case in the developed world — sunlight-readable, child- and abuse-friendly devices. Nice to know there is a market for that, and that it has discovered Pixel Qi.

SchoolServer WordPress Extensions

Adam Holt came through NYC this morning on his way to Jamaca, and was talking about extending the idea of schoolserver.wordpress.com. I was describing how I have come to see adequate electrical  power to be a strategic issue in the areas we are trying to serve.  He was describing the efforts of a lot of medium sized deployments to develop content — (he mentioned OLE).

Following on his suggestion,   I created two new wordpress urls: schoolserverpower.wordpress.com and schoolservercontent.wordpress.com.  I intend to start populating the power url with items relating to solar panels, batteries, monitoring equipment.  I’m not particularly involved with content development, but I see it as strategic.  (It seemed to me that grabbing the urls, for free, was worth the risk of them not being used).

I started the schoolserver blog a few months ago, mainly to force myself to use more discipline in documenting my trip to the Philippines.  But then Sameer Verma, asked if he could contribute to it also, and he documented how to create a virtual school server.

I read wiki’s many hours a day, and learn a lot from them.  But it’s also frustrating. I get distracted by ideas that turn out to be unimportant.  I hunger for a good textbook, covering the subjects I want to learn, with someone’s analysis of the relationship between the ideas — maybe with an index and a table of contents. It’s my hope that I can spend enough time learning and thinking about the school server, that  schoolserver.wordpress.com can become the best entry level introduction to the complexities of school servers.

I’m hoping that others might be willing to do the same for their areas of interest and help  impose reasonable structure on all the wiki information at laptop.org.

The Next Nightmare is Coming

BitTorrent was NEVER the Performance Problem

BitTorrent is a lightning rod on two fronts: it is used to download large files, which Some puzzle pieces of a picture puzzle.the MPAA sees as a threat to their business model, and due to BitTorrent’s performance impact on Internet. Bram Cohen has taken infinite grief for BitTorrent over the years, when the end user performance problems are not his fault.

Nor is TCP the performance problem, as Bram Cohen recently flamed about TCP on his blog.

I blogged about this before but several key points seem to have been missed by most: BitTorrent was never the root cause of most of the network speed problems BitTorrent triggered when BitTorrent deployed. The broadband edge of the Internet was already broken when BitTorrent deployed, with vastly too much uncontrolled buffering, which we now call bufferbloat. As my demonstration video shows, even a single simple TCP file copy can cause horrifying speed loss in an overbuffered network.  Speed != bandwidth, despite what the ISP’s marketing departments tell you.

But almost anything can induce bufferbloat suffering (filling bloated buffers) too: I can just as easily fill the buffers with UDP or other protocols as with TCP. So long as uncontrolled, single queue devices pervade the broadband edge, we will continue to have problems.
But new nightmares will come….

The Bufferbloat Nightmare

We can set BitTorrent and Ledbat aside here for a bit: they are not the actual problem and solution to our performance problems, and never were. Bufferbloat, and the amazingly stupid edge of the broadband Internet are.
Bufferbloat is fundamentally a different phenomena than Internet congestion we experienced in the 1990′s, something most people, including myself, have not understood well.

The AQM algorithm called RED was invented in the 1990s by Sally Floyd and Van Jacobson to control internet router congestion in router queues, but history has show RED is fundamentally flawed and usually left unused. RED cannot handle the variable bandwidth problem we have in the edge of the Internet. These results were never properly published, for humorous and sad reasons. At best, RED is a tool that may be helpful in large Internet routers until a better algorithm is available.

The article published last week entitled “Controlling Queue Delay” by Kathie Nichols and Van Jacobson in the section “Understanding Queues,” helps greatly in understanding queuing, as well as introducing a novel AQM algorithm called CoDel (“coddle”) to manage buffers which works radically better than RED ever did.  A clocked window protocol such as TCP (or others) can end up with a standing queue, adding delay that will never go away, killing speed. That standing queue cannot dissipate, and in fact (since TCP sees no timely loss), it slowly grows over time, as you can see in my original traces, and the delay grows and grows until any size buffer you care to name fills.

Worse yet, TCP’s responsiveness to competing flows is quadratic: 10 times to much buffering means TCP gets out of the way 100 times more slowly. Buffer queues must be managed; that is what an AQM does by signalling the endpoints the buffers are filling. But it is hard to figure out when to signal. No fixed buffer size can ever be correct, particularly in the edge of the Internet.

The fundamental problem is bufferbloat, and the amazingly stupid devices we have in the edge of the internet. These devices and computers typically having but one horribly bloated queue, with no queue management in them. The CoDel algorithm attacks the fundamental problem of standing queues, that RED did not, which required manual tuning. CoDel keeps buffers working the way they should: removing the standing queue, running usually nearly empty, so they can absorb bursts of packets that are inevitable in packet switched networks. The amount of buffering then becomes (probably almost) irrelevant, other than possibly costing money and power. For reasons I’ll cover shortly in another blog post, we think additional measures are also necessary; but the missing piece to solving bufferbloat has been a fully adaptive AQM algorithm that works well.  The rest is engineering.

Without some mechanism to signal the endpoints to adjust their speed in the face of buffers filling (either by packet drop or ECN), we’ll continue to have problems with everything (including HTTP) and everything built on top of TCP. CoDel, we believe, is the tool here.  Knowing a queue is filling excessively and managing it is a fundamental improvement over trying to inferring queue filling from delay.

Running CoDel code for Linux (dual licensed BSD/GPL2) is already staged in net-next for the next Linux merge window. Testing continues, but initial results match CoDel simulations. CoDel works, and works well.

You can build a delay based TCP, as was done in TCP Vegas,  it can lose out to conventional TCP’s and has some other unsolved problems. No vendor is going to want to ship something that can make their systems work worse relative to competitors. Getting everyone to convert at once all over the Internet is a non-starter. I do not see a path forward in that direction.

The complete bufferbloat solution is deploying CoDel in our operating systems, our home routers (which come from the factory with firmware that is based on at least five year old antique code), our broadband gear (which comes with a single queue, no classification or “fair” queuing) need upgrade or replacement.  Bufferbloat is also hiding elsewhere in the Internet, including our cellular wireless systems.

Back to BitTorrent and its history, and what we can learn from the incorrectly diagnosed nightmare it triggered.

Ledbat is engineering around bufferbloat, not solving it. It is a really clever idea: if you detect excess delay, you try to get out of the way of other traffic.
But it doesn’t attack the fundamental problem, which is managing the buffers properly in the first place in your OS, your home routers, your broadband gear, to avoid delay in the first place. Then your network will always work at full speed, and share resources among people without falling off a performance “cliff”, as it does today.

Netalyzr uplink data

My cable modem is more than 10 times overbuffered according to the grossly flawed 100ms rule of thumb, even with a 2Mbps up-link. The netalyzr data shows my modem is typical. My brother’s DSL connection, rather than the 1.2 seconds up-link buffering, has 6 seconds of buffering, at least 60 times the worse than useless traditional 100ms “rule of thumb”.  Tail drop is the worst of all possible worlds; you delay signalling the endpoints until the last possible instant.

At the time BitTorrent deployed, most cable customers had only a 256K to 768k uplink, with the same DOCSIS 2 modem; so rather than the 1.2 seconds I did on a 2Mbps uplink, it was correspondingly worse, and was comparable to my brother’s current DSL service.

BitTorrent filled these buffers. It was one of the first applications to be left running that would routinely fill the uplinks. BitTorrent was blamed since it was often found running at the time the network engineers looked to see why the customer was complaining.

ISP’s reduced their nightmare overnight with a configuration change: Comcast, for example, upped their minimum upstream bandwidth to 784Kb, the most bloated buffers became 1/3 the size in time overnight. Many customers had long since bought the 2Mbps upstream service. The video demonstrates just how bad typical bufferbloat is on 2Mbps. 784k (with the same cable modem) will be three times worse!

BitTorrent may have problems that make it disliked by ISP’s (having to do with large scale traffic shifting), but ISP’s really hate customers calling up unhappy: this comes directly out of their bottom line profit, and is a competitive problem as well (to the extent there is competition between ISP’s; at my house, there is none).

There is one fly in the ointment for uTP/Ledbat, however. Since CoDel will allow us to finally attack the real problem and keep delays low all the time, Ledbat will no longer sense delay and cease to be effective at keeping out of the way of TCP. Ledbat behaves like TCP Reno in that case.  This is what diffserv and “fair” queuing techniques were invented for. HTTP TCP traffic should have interactive priority, while downloads of all sorts, including HTTP downloads, BitTorrent, scp, and other bulk transport has lower priority. So if uTP/Ledbat also marks their traffic, we can deal with it in the edge of the network where we deploy CoDel and keep it from interfering with other traffic. We have to make our home routers and broadband less stupid; AQM is necessary, but not sufficient to get us a “real time” Internet. More about this soon.
Our edge network devices and our computers are stupid and broken.  Most ISP senior executives likely still think it was BitTorrent causing their nightmares. It wasn’t BitTorrent’s fault at all, in the end. It was bufferbloat. Anything else you do with TCP or other protocols can and does cause serious problems. So long as we are stupid enough to think memory is free and how buffering is handled doesn’t matter, we are doomed. So get off of Bram’s case.

Network Neutrality and a Call for Transparency

Those who think they understand the network neutrality debate triggered by BitTorrent and do not understand bufferbloat and its history are wrong. Both sides of this debate need to step back and rethink what happened in its light. A new application, BitTorrent, deployed which caused ISP’s real severe operational nightmares. Their phones were ringing off the hook with unhappy customers due to horrifying performance. I made the same service calls about terrible performance, but I wasn’t using BitTorrent.

The ISP’s bufferbloat nightmare was hidden: no ISP wanted to admit they had a serious performance problem in public, and they misdiagnosed the real cause. BitTorrent is often left running for long periods; so it often happened to be present when ISP’s would troubleshoot. In secret, measures were taken to try to control the nightmare. This lack of transparency was the root cause of the blow-up. Opacity contributed for a half a decade delay diagnosing and understanding bufferbloat. It will take at least a half a decade to deploy fixes everywhere they are needed.

We can expect future problems like this unless there is much greater transparency into operational issues occurring in networks in the Internet. The Internet engineering community as a whole, did not have enough eyes on the problem to diagnose bufferbloat properly when bufferbloat first became severe. A very senior ISP engineer played the key role in bufferbloat’s final diagnosis, handing me the largest number of the pieces needed to assemble my dismal puzzle, and closing the loop to both ICSI and Dave Clark’s warning to him about the “big buffer problem”, but diagnosis could and should have happened five years earlier. Problems take much longer to solve when few people (even the very capable ones at that ISP) have access to the information needed for diagnosis.

When similar events happen in the future, what should we do then?  How do we quickly diagnose and fix problems, rather than blaming the mostly innocent, and causing complete confusion on the root cause? What do we do while figuring out how to fix problems and deploying the fix?  Sometimes it will be a simple and quick fix. Sometimes the fix will be hard and lengthy, as in bufferbloat.  Sometimes the fix may be the application itself, that is badly designed (and we should think if the network needs ways to protect itself). Sometimes it will make make sense to manage traffic, in some (neutral) way, temporarily.

When will the next operational nightmare occur?  And how long will it take for us to figure out what is going on when it happens? Will the right people be contacted quickly? How and where do operational problems get raised, and to whom, with what expertise when they occur? How, when, where, and with whom is information shared for diagnosis? Should there be consequences for hiding operational problems? How do we best observe the operating Internet? The need for transparency is the fundamental issue.

We are flying on an Internet airplane in which we are constantly swapping the wings, the engines, and the fuselage, with most of the cockpit instruments removed but only a few new instruments reinstalled. It crashed before; will it crash again?

For the next growing nightmare is certainly already hidden somewhere.

It is when, not if, the next nighmare comes to haunt us.

Trimslice Successes — and small steps for XS-1.75

I had a USB to SATA hard disk adapter, so I downloaded the trimslice precompiled FC 17 release at http://blc.fedorapeople.org/fedora-arm/f17/ and copied it onto a 320 GB laptop drive. I followed the README, fetched xzcat, and executed “xzcat f17arm-latest-armhfp-trimslice-sda.img.xz /dev/sda” to copy the file across via the USB adapter to the hard disk. With some disbelief, I stuck the SATA drive in the Trimslice, (there was a nice little disk bay on the bottom of the solid aluminum casing), powered it on, and attached a serial cable. To my amazement, I was presented with a logon prompt!  I very seldom have something just work the way this did.

I downloaded “Development Tools” successfully, scp’d the olpc kernel git tree from my other machine, and proceeded to compile the kernel successfully.  I put the newly compiled kernel and modules on a USB stick, on top of a FC17 rootfs, ran dracut, adjusted olpc.fth in the /boot folder, stuck it in a XO-1.75, and booted to the point where the libertas driver module blew up.  After modprobe.d/blacklisting libertas, I got a login prompt.  I’ve been working to get a kernel that I compiled to work on the XO for two weeks. So the Trimslice turns out to be a means to compile ARM code, in addition to being a target down the road for XS software.

There are some wrinkles with the Trimslice build, of course.  A USB stick is discovered during the boot process, but subsequently, inserting a USB stick creates no entries in dmesg, or /var/log/messages. So sneakernet doesn’t work.  Fortunately, a USB ethernet dongle provides easy access.

So next, I can start recreating RPM’s for XS on the Trimslice. I have some learning to do there.

Eabametoong First Nation (Fort Hope, Ontario)

 

Flying into Eabametoong, also known as Fort Hope, you can’t help but be impressed by the trees. Forest cover is vast and this hasn’t been lost on the school, where students take advantage of their surroundings by participating in all season outdoor education.

John C. Yesno Education Centre houses local students from grades 1-9. After grade 9 students who wish to pursue further studies must relocate to a larger community such as Thunder Bay. Students in grades 1 through 6 have received their own laptop through the OLPC Canada program.

John C. Yesno has a full time computer teacher, who has taken a leading role in the OLPC Canada program at this site. Barry visits each class once a week to facilitate a lesson using the XO laptop. On my first day at this site, Barry took the grade fours outside to take close up pictures of the landscape with their laptops. Students were asked to imagine the captured landscape from a bug’s perspective. What might a a puddle look like to an ant? What might a patch of sand look like to a caterpillar? Students then imported their photograph into paint and drew a bug that fit the scene. The illustration was completed with a short story using Write. Watch for illustrations of this activity from Attawapiskat. Thanks for the inspiration Barry!

During the visit the Grade 5/6 students began a unit on data for math class. Teacher Courtney took advantage of the Ubuntu side of the XO, asking students to create a bar graph representing the populations of capital cities in Canada using gnumeric. The information was collected from Wikipedia on the Sugar side of the XO.

Kevin’s grade four class was busy practicing time telling, and elected to create a memorize game using clocks that they had drawn themselves. Students folded a piece of paper in four and drew a clock with a different time in each square. The clocks were digitized using the laptop camera, and then inserted into the memorize activity. By pairing and drawn analog clocks with digital time, students were able to practice time telling using diverse methods.

Thank you to the students and teachers of each of the seven classrooms that participated in workshops during this visit. A special thank you to Vice Principal Nick for facilitating the visit and Teacher Juliana for her hospitality.

Battery Experiences at Ecole Shalom — Haiti

When I was in Haiti, I saw how important the lead acid battery bank was to their lives. At Ecole Shalom, they had just been connected to the grid the preceeding May. (I was first there in November). During the time I was there, the power went off during the afternoon or evening on most days. It was clear that many of the teachers didn’t have power at home, as they were always plugging in their chargers and phones during the school day.

When I arrived, I discovered that four of the eight batteries used to provide power to the 110V circuits were not functioning.  By looking at the specific gravity in each cell, I noticed that one of the batteries had a very low charge level.  Later, as I was doing a cleaning operation on all of the copper cables that connected the batteries to one another, I noticed that on the battery that had the low charge, there had been a transfer of metal from one side of the connector to the mating half.  This usually happens where there is enough sparking and heat generated to melt the copper.  I guessed that the nuts holding that particular cable to the battery had not been tightened properly, that the heat generated had boiled the acid out of the battery. The water had been replaced, but the sulfate was trapped on the plates, and the battery was dead.  We replaced the battery, and the system worked much better, even though the experts on the web suggested that it wouldn’t work very well to put a new battery into an already existing array.

The inverter, shown in the picture on the table, is able to display a number (0-100) which the manual says is the percentage of remaining charge. Everyone was confused when that number became 100% after the power came back on.  I tried, it seemed to me unsuccessfully, to explain that the machine was actually measuring the voltage of the batteries, and using a well known translation table and relationship between voltage during discharge, and remaining stored charge.  That relationship does not exist during the charging phase.

As an experiment, I purchased a battery monitor from Xantrex, which monitors the current from the battery, and displays the degree of charge or discharge expressed as a percentage. This battery monitor turned out to be much more useful, and believable, then the display on the battery charger had been, because it was consistent whether the battery was on its discharge or charge cycle.  It would also keep track of the actual current out of and into the battery, and show changes in the system’s health over time.

I also had the feeling that there was little awareness of the need to use the equalizing feature of the battery charger (which is initiated by putting a paper clip into a small hole on the control panel of the charger). This equalizing process applies an extra large charging voltage which causes gassing and mixing of the electrolyte, and dislodges the sulfate crystals which coat the surface and lead to early battery failure.

As a techie and an engineer, I kept wanting to provide more visibility into the health of the battery system and make the removal of the sulfate crystals more automatic.

Punjab government to distribute 125,000 Ubuntu laptops to university freshmen

The initiative, launched last month with distribution to the first 1,500 students, is being promoted by Nawaz Sharif and secretary of higher education Kashif Faraz. Umar Saif, who runs the Punjab Information Technology Board, writes about this as the start of great opportunity for every child in Punjab.

It is good to see Pakistan making strieds in this direction, though they like India have chosen to start access to laptops, software, and knowledge with university students.

It is not change that causes anxiety; it is the feeling that we are without defenses in the presence of what we see as danger.

I’m tired of people saying things like “oh, people are naturally resistant to change” or “everyone’s afraid of change” or “change is hard,” and treating those statements like Immovable Axioms that One Cannot Change Or Argue Against. They’re not entirely untrue; change is sometimes hard and scary. However, we’re not going to get anywhere if we use that as an excuse for not looking deeper.

It is not change that causes anxiety; it is the feeling that we are without defenses in the presence of what we see as danger… –Kegan & Lahey, Immunity to Change

I love the first part. Seriously, folks; I put on a new t-shirt every day, but that doesn’t cause me to go into paroxysms of fear as I stare at the closet in the morning. I’d be bored to tears if I had to eat the same thing for dinner every night, and think nothing of the sky going dark every evening. I look forward to starting new classes, getting new books, to the births of my new little nephews (welcome to the world, Oobs and Ewan!) We go through tons of changes that we’re not the least bit anxious about. (Okay, maybe my cousins were anxious about their babies being born, but I sure wasn’t.) Point being: not all change causes anxiety.

So what does? That’s the second part of the quote. There are two parts to it that I want to highlight.

It is the feeling that we are without defenses.

The feeling. Not the objective reality (if there is such a thing). If someone believes they are defenseless — if they don’t realize there’s a safety net, if they don’t think others will step in to protect them, if they don’t trust their own abilities to make everything okay — regardless of the situation, they will be afraid, and they will probably resist change.

In the presence of what we see as danger.

Again, subjectivity. If you don’t see something as a danger but someone else does, then of course they’re going to be more anxious than you. This works the other way around too; my parents and boyfriend are a lot more concerned about me walking around strange cities alone at night than I am.

And note that these two things together; if I’m without defenses but am confident that no danger will arrive, I’m not anxious — actually, I feel pretty safe. For instance, I feel fine walking around my apartment barefoot because I know there aren’t sharp things on the floor that could hurt me. And if you’re in the presence of something you think is dangerous, but you have defenses you feel are sufficient, you’re also going to be just fine; I know I would stand no chance against a full-grown tiger, but had no problem watching one pace behind thick glass the last time I went to the zoo.

Implication: to fix anxiety (whether it’s linked to change or not), make the fearful person either (1) feel like they’re well-protected, or (2) believe that what they’re seeing isn’t dangerous.

Sounds simpler than it is; this is still hard work. But it’s a heck of a lot better than going “well, people just don’t like change!” and throwing our hands up and walking away.

The XO laptops are better than our teacher’s expensive laptop

The XO laptops are better than our teacher’s expensive laptop
We have been busy this week. Out teacher Mr. Amunga has been busy making a video of Sydney and his story on Xo and his family. Meanwhile he left us to browse the internet using our xo laptops. He also left something behind for us to examine carefully. His, dell laptop.
We just discovered that adults like using and buying big expensive laptops that are different from our xo laptops.. But we think our xo is more intelligent and a better computer than Mr. Amunga’s Dell laptop. First we discovered that XO laptops (from OLPC) do not need Internet cables. They only connect wirelessly and don’t even have a place to plug in an Internet cable. You just need 2 wires to connect the appropriate type of modem to your Internet coming from the town and then to connect a wireless router to the modem.
That is: Internet —- Modem —— Router )))))) wireless (((((( XO laptops. Plan to have the router somewhere inside the classroom. The wireless signal does go through walls, but it is weakened by the wall. You may be able to use the laptops on the Internet outside of the classroom, too.

Electric power should not be a problemto us as it is to Mr. Amunga’s Dell Laptop. . The xo’s can work for hours on their battery alone, which they can recharge from the solar power during the day, or indefinitely while they have solar power coming in. It may only be a problem if you have many days of dark weather, actually an xo in Eshibinga uses less power than our teacher’s Dell laptop computer.

Finally, xo’s have a software called Sugar. It is good for children aged 6 to 12 years old. We got to read about Sugar here: http://wiki.laptop.org/go/Sugar. This is a good manual to start with: http://laptop.org/8.2.0/manual/. It explains how to set up the network, too. Every kid in Africa will love sugar. It has activities just ment for us. Can you imagine, Mr. Amunga’s dell laptop is very expensive? Yet it does not have sugar. How do these adults work on computers that have no sugar? I just sympathise with them…

One of the best collections of lesson plans I have seen, but still limited (10 examples) and doesn’t incorporate some of the more complex activities we have been trying to use: Turtle Blocks /Art (got one mention), Etoys, Physics.  That said, the lessons look great and we have a lot to learn from theme.

These lessons also assume the XO, but we use SoaS.  Record is a popular program in these lesson plans, but when we use SoaS on desktops, no camera for Record. We had some luck, but not fail proof, using Record with netbooks equipped with cameras.

OLPC School Server | George Hunt

Arm progress on XO-1.75

About 2 weeks ago, I downloaded a FC17 ARM root file system onto a USB stick.  I took the kernel and kernel modules from a recent build of the XO=1.75, and plopped them on top of this rootfs. Much to my amazement, it booted, and presented me with a logon prompt.

It feels like it’s been all downhill from there. But in actual fact, I’ve been learning a lot — dealing with all of the failures:

  1. My first thought was that I might be able to download development tools, and compile the School Server RPMs on the XO, and be done with it. I was able to do a groupinstall of the “Development Tools” and start compiling the XS rpms. Creating  rpms is a new experience for me, and I’ve had some learning experiences, and slow starts. But then I started having segmentation faults on the XO during compiles. The compiler generated an error message which suggested that the segment fault might be an OS problem.
    I decided that I needed a clean rebuild of the kernel (and maybe eliminate the mismatch between fc17 root fs and an earlier kernel build from the XO –based on fc14).  At first I tried to compile the kernel on the XO, but I kept running into the same seg fault which stopped me from working on the RPMs. I started trying to cross compile the kernel on my laptop.
  2. The first cross compiler I tried was suggested in the Fedora ARM wiki.  But this cross compiler was generated in the FC12 timeframe.  When I started using it, I discovered that it generated errors.  When I googled the errors, it seems that the syntax for assembly language constraints has changed.  I tried the free cross compiler from CodeSourcery — lite which did not generate the same errors.
  3. The OLPC wiki suggested that I use a cross compiler from crosstool.ng.  It turns out that this is really a compiler to generate cross compilers.  There were errors when I tried to generate a cross compiler, and after 2 days I gave up trying to generate a cross compiler for ARM eabi.
  4. Since the CodeSourcery lite cross compiler worked, I started trying to use the OLPC kernel source from their git repository to demonstrate to myself that I had the tools and competence to recreate the kernel similar to the one that I already had running on the XO.
  5. Four days and five compilations later, I’m still in that process.   So far I have discovered:
  • That it’s very easy to slip up and specify that a driver should be a  module, when it really  needs to be built into the kernel, so that it can mount the root file system.
  • That when you use dracut on a cross compiling intel machine, dracut includes an intel version of modprobe which does not work very well loading modules on and  ARM machine — that dracut needs to executed under an older functioning kernel on an ARM machine in order to work properly.
  • That not all drivers have ARM headers and implementations, and must not be selected in a cross compile

A few weeks ago, when I asked about low power ARM computer candidates for School Server, Peter Robinson, who is active in Fedora ARM software development, suggested the Trim-Slice H.  I ordered one, and it came in the mail yesterday. I’m very eager to play with it.

I put a SATA 320 GB hard disk in the disk bay of the TrimSlice, and put it on the watt meter.  With the draw from the hard disk, it draws 5.3 watts! Together the disk and computer cost $350 (computer $280, hard disk $50, ethernet dongle $20). In much of the developing world, I believe the cost of deep cycle batteries, solar panels, and maybe even the long term cost of power from the grid will overshadow the original costs of the computer hardware.

Even cheaper solutions include the Tonido plug at about $195 ($125 for plug,$20 for ethernet dongle, $50 for hard disk), and the XO1.75,  at about $290$ (XO itself, ethernet dongle $20, hard disk $50 and USB hard disk enclosure $20)

Australian brilliance: AU government provides $11.7M for OLPC pilot

via Rangan Srikhanta

It gives me tremendous pleasure to inform you that the Australian Federal Government has committed to fund One Laptop per Child in Australia for $11.7M this year, to launch a pilot project to reach 50,000 children in indigenous communities.   Additional funds will come from the schools participating in the program and from corporate/public donors.

From the Schooling section of the annual budget:

The Australian Government is providing over $11 million to support the One Laptop Per Child (OLPC) Program which will deliver over 50,000 custom built laptops to primary students in regional and remote Australia as part of a 12 month pilot program. The OLPC Australia Organisation (OLPC Australia) aims to support the learning opportunities of indigenous children, particularly those in remote Australia, by providing primary school aged children with a connected XO laptop as part of a sustainable training and support program. Participating schools will also receive information and communications technology (ICT) coordinator professional development, local repair kits, and access to helpdesk and online support.



From the
full budget breakdown, It seems that some of the funds for this was redirected from a project pool for the “Digital Education Revolution”.   The government is also extending OLPC Australia’s tax-deductibility for another three years, as part of this continuing commitment.

This is fantastic news.  Kudos to Rangan, Sridhar, Tracy, Rita, Sasha, Ning, and the whole team. A formal press release will be out in the coming days.  There is much more to come from Australia — stay tuned!

Fundamental Progress Solving Bufferbloat

Kathie Nichols and Van Jacobson today published an article entitled ”Controlling Queue Delay” in the ACM Queue. which describes a new adaptive active queue management algorithm (AQM), called CoDel (pronounced “coddle”). The article will appear sometime this summer in the Communications of the ACM. Additionally, another independent adaptive AQM algorithm by other authors is also working its way through the academic publication cycle.

A working adaptive AQM algorithm is essential to any full solution  to bufferbloat. Existing AQM algorithms are inadequate, particularly in wireless with its very rapid changes in bandwidth.

Everyone working in networking, not just those interested in AQM systems, should read the article, as it dispels common misunderstandings about how TCP interacts with queuing.

CoDel (“coddle”) is a novel “no knobs”, “just works”, “handles variable bandwidth and RTT”, and simple AQM algorithm. To quote from the article,

In the decade since, many researchers have made strides in AQM, but no one has produced an AQM that has the following characteristics:

  • It is parameterless—it has no knobs for operators, users, or implementers to adjust.
  • It treats good queue and bad queue differently—that is, it keeps the delays low while permitting bursts of traffic.
  • It controls delay, while insensitive to round-trip delays, link rates, and traffic loads.
  • It adapts to dynamically changing link rates with no negative impact on utilization.
  • It is simple and efficient—it can easily span the spectrum low-end, Linux-based access points and home routers up to high-end commercial router silicon.

and:

CoDel’s algorithm is not based on queue size, queue-size averages, queue-size thresholds, rate measurements, link utilization, drop rate or queue occupancy time.

Without an AQM, a  standing queue can be normal result of TCP’s window mechanism, and is not “congestion” as most people have understood it. And since TCP attempts to run a link as fast as it can, any bulk data transfer will cause a modern TCP to open its window continually, and the standing queue grows the longer a connection runs at full bandwidth, continually adding delay unless a AQM is present.  Attacking this standing queue is why an AQM is essential in the Internet; and then TCP can be properly responsive to competing traffic.

Network traffic patterns change unexpectedly and rapidly, particularly in the edge of the Internet. Any algorithm requiring manual tuning is unlikely to be configured when and where it may be needed. Common available AQM algorithms (e.g. RED and variants available in today’s routers) can hurt you if misconfigured. The lack of an algorithm that obeys the medical maxim of “First, do no harm” has meant that queue management is often/usually disabled even on Internet routers where it could and should be used (until better algorithms such as CoDel are available). AQM is unavailable on many devices where we now understand it is necessary, including our hosts, laptops, smartphones and other devices. The hope and belief is that CoDel is such a “do no harm” algorithm, that can always be “on” so it can work its magic whenever it is needed.

Mechanisms such as “fair” queuing and traffic classification are also needed for a low latency edge of the Internet, and to try to solve all issues in an AQM algorithm leads to unnecessary complexity and inflexibility, but those other necessary components are  well understood and I will blog about them soon.

A small meeting among people interested in ethernet and WiFi implementations was hosted by ISC less than two weeks ago, where we saw the CoDel  algorithm for the first time. Ethernet implementations should be straight-forward in most operating systems (if they have a BQL like system to control buffering in device drivers). Wireless and other technologies may be much more difficult, both because queuing is sometimes much more complex than Ethernet, but also since packet aggregation has resulted in OS/driver boundaries hiding information that is necessary for proper functioning.  Green ethernet, TSO/GSO are also complicating problems.

A preliminary Linux implementation of CoDel written by Eric Dumazet and Dave Täht is now being tested on Ethernet over a wide range of speeds up to 10gigE, and is showing very promising results similar to the simulation results in Kathie and Van’s article. CoDel has been run on a CeroWrt home router as well, showing its performance.

Other technologies and environments will be a greater challenge; for example device drivers using Linux’s Mac802.11 framework aggressively pull packets from Linux’s packet queuing system in order to perform packet aggregation, removing the packets from Linux before the current CoDel prototype would get a chance to act on them.

There will be aspects of CoDel needing tweaking for some technologies or environments, along with interactions with queuing and classification systems. Work to integrate adaptive AQM algorithms into wireless systems will take months or years, rather than the week that initial CoDel prototype implementation for Ethernet took. But at least much testing of the CoDel algorithm, experimentation, and refinement can now take place.

Kathie Nichols’ NS2 simulator implementation will become available soon; her CoDel web page is located at: http://www.pollere.net/CoDel.html. Andrew McGregor has written a preliminary NS3 patch.

Discussions about CoDel take place on the codel@lists.bufferbloat.net mailing list. Discussions about bufferbloat in general, and how to attack latency on the edge of the network, takes place on the bloat@lists.bufferbloat.net mailing list. CeroWrt, an advanced build of OpenWrt where our bufferbloat experiments take place, has its development discussions on the cerowrt-devel@lists.bufferbloat.net mailing list. Real time discussions take place on the #bufferbloat channel on IRC on freenode.net.

Both financial and programming/documentation support for both CeroWrt/OpenWrt are needed. We now have the tools in hand to make a home network that works well, at last!

Bright Ideas on Birch Island

Whitefish River First Nation hosted a visit from OLPC Canada representative Jennifer Martino from April 23-27. Over the course of the visit students and teachers demonstrated their creativity and skills using the XO laptop.

 

Grade 5/6 class participated in a Scratch workshop and showed impressive aptitude for programming. The Smart Board proved to be a useful tool for experimenting with Scratch in a classroom setting (to use Scratch with a smart board download the PC, Linux or Mac version at www.scratch.mit.edu).

Students were able to interact with the program during a teacher lead demonstration, followed by individual work on their XO laptops. At the end of the school day student Scratch projects were assigned as the very first XO homework assignment.

 

The Grade 2 class had lots of fun using Memorize to create electronic flash cards based on their favorite storybook character: Amelia Bedelia. Words of the day included: unfold, unhappy, uncover and unknown. Students took pictures of themselves enacting these words and then created matching pairs using Memorize.

 

 

Geography was the theme of Grade 3 work with the XOs, using Wikipedia to identify provinces and corresponding capital cities.

The top English Wikipedia articles come preinstalled on the XO so no Internet connect is required. Students recorded the information into their notebooks and created flash cards using Memorize.

Thanks to Whitefish River for hosting this visit and for enthusiastically demonstrating creative technology enhanced learning!

OLPC SF

We be crankin'

Here are two observations:

  1. If you've ever used the OLPC crank charger, you'll know that while it works as advertised, it takes a lot of cranking. The charger would work better if it could be attached to a wheel. Then, you could rotate it by fitting it on to a bicycle, a sewing machine, etc. To that end, I took apart the handle and saw that one could easily fit a small wheel on to the shaft.

  2. On one of our usual visits to UCSF, I was walking by their clock, when it struck me (no pun intended) that the clock is a large wind-up mechanism that stores potential energy by pulling up large weights to a significant height, and then trickles it into the clock mechanism to power it. You may have seen something like this in a cuckoo clock. Alex and June Kleider have a similar mechanism at their place to roast a pig (community summit bbq party goers must have seen it).

    UCSF Clock Mechanism

Putting the two together seemed ideal. So, I discussed this with Joachim Pedersen, our OLPC SF repair guy, who also runs a course at SF State on desigining objects, gears, tricopters, and other such serious research (something to do with materials, evidently). We spoke with a student (Bret Cooke) who was interested, and after a few tries, and design changes, we got a 1:6 ratio gravity charger design going. This prototype was on display at the recent SF State University Science and Engineering showcase. His description of the project is:

 

The mechanism is a planetary gear (1:6 ratio) hub that has a outer gear wheel which takes a length of string. The string goes over a pulley and has a weight on the other end (a 1 gallon water jug). The mechanism itself can be attached on to the charger easily.

Noah's Graduation — Bangkok, Thailand


Bangkok, Thailand




We planned this trip to Bangkok to attend and celebrate our son, Noah's graduation from Ramkhamhaeng University.

Today, Noah received his baccalaureate degree in Business Finance personally from the beloved Princess Maha Chakri Sirindhorn of Thailand. Along with the other families of graduating students, we watched from an adjacent site on television as Noah respectfully bowed four times and clasped his degree to his heart!

Many Monks and other special invited guests were in attendance all day. Noah was the only westerner to graduate this day among his 4,150 classmates. Sumalai's parents, Wat and Jong, traveled from Khon Kaen, her Aunt "Wow," came also, along with close friends, his business partner and employees. We had a celebratory lunch at Fuji (Japanese) and dinner at Le Lys, (French Thai) both delightful and delicious.

It was a very long, hot, and definitely off the tourist beat day in Bangkok. We were delighted to be in the company of so many joyous Thai families, and to meet our son's friends and classmates. Congratulations Noah for your remarkable accomplishment in this very competitive university business finance program!

A Well-Planted Seed

IEEE Foundation grant enables technology for development project to grow

By LAURA HOSMAN 20 April 2012

Reposted from http://theinstitute.ieee.org/ieee-roundup/opinions/ieee-roundup/a-wellplanted-seed

main
The IIT team displaying their Solar Computer Lab in a Box prototype during their school’s university-wide presentation day.

Editor’s Note: IEEE Member Laura Hosman is assistant professor of political science and associate chair in the Department of Social Sciences at Illinois Institute of Technology. Her research focuses on the role for technology in developing countries, particularly in terms of its potential effects on socio-cultural factors, human development, and economic growth.

Last month at a conference in Atlanta, I attended the panel “Sustainable Information and Communications Technology for Development (ICTD),” where IEEE Foundation past president Richard “Dick” Gowen, spoke about the IEEE Foundation’s goals and methods for contributing to sustainable applications of ICT for development. Dick’s presentation hadn’t been listed on the program schedule, so my excited mind raced in anticipation of introducing myself and describing my own IEEE Foundation-funded project (US$17 000) to deploy a 2.4 KW directcurrent (DC)-only solar powering system at a primary school in Lascahobas, Haiti.

I moved closer to the edge of my seat as Dick described another IEEE Foundation-sponsored project in Haiti, the Sirona Haiti Rural Electricity Project, which I knew about, and am so impressed by. What’s more, I thought to myself, both projects employ the same DC-only approach; my team had worked with the same Haitian solar provider that Sirona had, Sirona’s project was featured in The Institute Online (Lighting Up Haiti,” April 2011), and my project was going to be, too in “Keeping Laptops Alive in Haiti.” I couldn’t wait to tell Dick how much these projects had in common!

I nearly fell off my chair when Dick revealed that SironaCares had received an initial investment of US$350 000 from the IEEE Foundation. After regaining my composure, I began to think instead about how small—even miniscule—my project and the Foundation grant seemed by comparison.

I did introduce myself to Dick after the panel, and described my project (which he had heard of), but I’m sure I was far less bold than I had intended to be at the beginning of his talk. I’ve thought quite a bit over the past month about why this was the case, and have come to the realization that there are also wonderful things that can happen from seed funding, which is how I now think of my team’s IEEE Foundation grant.

Smaller amounts of money can mean very careful stewardship because the funds are so precious. More importantly, however, is that they still enable a good idea to be implemented. And very few good ideas are perfect in their first implementation! This provides a valuable opportunity to take stock and move forward in an even more promising way. I’m happy to say that I believe we’re on the path to doing just that.

We were, thanks to the IEEE Foundation grant, successful in deploying our solar powering system in August 2011. These funds also helped enable our second deployment, when we connected the school to solar-powered Internet and WiFi in December 2011.

However, in November 2011, we learned that Haiti’s Ministry of Education’s priorities had rather abruptly shifted away from this project. They had been more than a central partner in this endeavor; they had invited us to work on a replicable, affordable solar solution for powering technology in the schools. Moreover, they were the partner we were counting on to scale, maintain, and take over the project.

As a political scientist who focuses on both ICTD and public-private partnerships and for whom this was my first project as a true practitioner, I can only appreciate the sweet irony of the public partner (and project initiator) dropping its interest in this ICTD project for political reasons. What a learning experience!

We did a considerable amount of soul-searching during the December trip, pondering how to move forward and incorporate the lessons we’d learned over the past few years.

We came up with a Solar-Computer-Lab-in-a-Box solution that can be deployed anywhere in the world where energy resources are too expensive, unreliable, or non-existent. The turnkey solution features six low-power laptops, two solar panels with mounting gear, and a pre-wired charge controller, all in a shipping box that transforms into the computer lab table. The solution seeks to address the overwhelming global demand for technology in schools, while simplifying the installation, powering, and maintenance of the actual technology, down to a bare-bones minimum. It’s also a nod to the teachers who I’ve interviewed around the globe who tell me they want a computer lab in their schools so they know the computers will be there when they want them, with one person in charge of training and maintenance.

My team of students at IIT has worked on the project’s new direction—the lab in a box—since January. We’re unveiling our prototype on 20 April. There have been many NGOs and even public and private entities interested in our solution, and we’re planning to deploy the first system (along with solar-powered Internet and WiFi) this summer on a rural, isolated island in Chuuk, Micronesia. Mindful of the fact that technology is only a fraction of the real solution, we are also proposing the project as a capacity-building partnership with locals and the country’s Department of Education, and carrying out training to make this a long-term, locally sustainable and replicable solution.

In the end, our small, seed IEEE Foundation grant enabled us to successfully carry out our pilot project, redesign our solution for even greater scalability, wider applicability, and really move forward after experiencing and then planning for what it takes to make technology-in-the-schools solutions locally owned and sustainable.  Small can be beautiful: Thank you, IEEE Foundation!

OLPC School Server | George Hunt

School Server, Holodeck style

We are not quite there yet, but virtual machines always remind me of Star Trek’s Holodeck – a virtual world, where the OS thinks it runs on a real machine, but it can be “paused” at will and shelved away until a later date.

To take advantage of this setup, and to play around with a school server, I have put together a VM of OLPC XS 0.7 This version has been installed, but not configured. To get started:

  1. Grab and install a copy of your favorite virtualization platform such as VMPlayer or Virtualbox. I use VirtualBox under Ubuntu 12.04 LTS, which is where I built this VM. Your experience with other VM environments may vary.
  2. Download the OVA file from http://dev.laptop.org/~sverma/xs/olpc-xs-0.7.ova.zip
  3. Unzip and check the md5sum hash of olpc-xs-0.7.ova. It should be 8eeed031780bc8d2c87915bc48ee27c8
  4. In VirtualBox, go to File | Import Appliance and point to the OVA file. This will import the VM into your machine. Be sure to adjust the RAM etc. to your liking. I’ve set it at 1024MB.
  5. Start your VM. When booted up, login as root. Password is we’rejammin’  (and I hope you like jammin’ too!)
  6. As a good administrator, change the password to your liking.
  7. Remember, this VM is not configured, so set it up.
  8. For example, xs-setup olpcsf.org will set up your XS to run at schoolserver.olpcsf.org Choose a domain of your liking. Because this is in a VM, and can be turned off at the flick of a switch, anything is ok. Even microsoft.com is ok, but we won’t like you very much.
  9. Now, we need to set up the networking. The VM comes only with the lo interface. So, run xs-setup-network and this will set up eth0 as the LAN interface. This interface will be spewing IP addresses via DHCP when you reboot the VM. So, before you reboot the VM, set its networking to bridging, and bridge it with the interface that you want it to spew at. For instance, I chose to bridge eth0 in VM and eth0 on my host laptop. That way, if I connect a AP to eth0 on my host laptop, it will be serving IPs to any XO that connects to it. Make sense?
  10. All set? reboot
  11. When the VM comes back up, you will see that eth0 now has an IP (the XS runs at this IP). It will also be serving IPs via eth0.
  12. Next steps? Use your server to test out Moodle. Try adjusting the RAM and CPU allocations and see how the XS behaves. Use your VM to train teachers, impress friends, be a Trekkie and say “Computer, end program“.
  13. See http://wiki.laptop.org/go/XS_Installing_Software for more.

Is SoaS ready for prime time?

We’ve been using Sugar on a Stick (SoaS) for almost two years now in after school programs, and generally its performance has been acceptable.  I wouldn’t want to be a classroom teachers with 20+ kids trying to make it work, but 12 kids in an after school program is doable. When a stick fails, we  just swap it out and give the student a new one.  Occasionally, a student would get two that failed, and become frustrated, but in a 45 minute session, that isn’t the end of the world.

Today, we had so many failures we lost track.  We only had 10 kids, 6 sticks working (at least initially), and eventually 8 worked with two kids doubling up.  We also had to break out 2 laptops because part of the failure seems to be related to the desktops we are using, but even the success-fail rates with the desktops are totally random.  Computers that worked fine last week didn’t work this week.  Computers that did not work last week did work this week.  I suppose the logical thing to do in order to track success and fail rates is to put the same sticks in the same computers every week.

I am just wondering who is using SoaS on a regular basis in a school or after school setting, is it similarly problematic in other settings, or are we doing something wrong with our imaging of sticks?

Bufferbloat goings on…

The bufferbloat front has appeared quiet for several months since two publications hit CACM (1), (2) and several videos hit YouTube, though I have one more article to write for IEEE Spectrum (sigh…).

There has been a lot going on behind the lines, however, and some major announcements are imminent on ways to really fix bufferbloat. But I wanted to take a moment to acknowledge other important work in the meanwhile so they do not get lost in the noise, and to get your juices flowing.

  1. First off, Linux 3.3 shipped with BQL (byte queue limits) done by Tom Herbert of Google.  This is good stuff: finally, the transmit rings in Linux network device drivers won’t cause hundreds of packets of buffering.
  2. Dave Taht has had good success prototyping in CeroWrt a combination of Linux’s SFQ and RED to good effect: SFQ ensures decent sharing among short lived interactive flows which receive preference to long lived elephant flow TCP sessions. As transient bufferbloat and TSO/GSO GRO/LRO smart NIC’s make clear, no comprehensive solutions for achieving good latency are possible without some sort of “fair” queuing and/or classification. As in all RED based AQM algorithms, tuning SFQRED is a bitch and a better AQM is badly needed; news at 11 on that front. CeroWrt is approaching its first release with all sorts of nice features and I’ll blog about it when it’s soup. In the meanwhile, adventurers can find all they want to know about CeroWrt at the links here.
  3. The DOCSIS changes to mitigate bufferbloat in cable modems continues on its way.  While I haven’t checked in to see when deployment really starts (driven by modification to cable carrier deployment systems), we should see this major improvement later this year.

And, as outlined in other writings on this blog, and demonstrated in this video, you can do things about bufferbloat in your home today.

So there is hope.  Really…  Stay tuned…

Cities for Coders

At Code for America, a great deal of thought goes into what's possible with apps. But I miss the reflection which came with OLPC, the question of where programmers come from in the first place.

It's actually super-relevant to our work in cities, because not every city fosters a programming community. Most cities have a dedicated and hard-working IT department, but local coders provide the lifeline for new ideas and skills, an unofficial partner in apps and hackathons. Think of RAP Ceibal's work in Uruguay.

My city team's strategy focused on a local university. I made a few appearances at MUGTUG, a late-night CS meeting where students share projects centered around Google APIs. In the future, we hope to drive this group to develop a musical map of the city ( something technical, but not overwhelming ). But for the most part, CS students aren't taught languages of the web. It's so odd - I mean, the world is web. But two weeks ago, a Berkeley grad student told me that she'd quit Codecademy, because her professor wants her to focus on Python.

My own experience? I like learning while working - the start-up way. This year I have completely overhauled how I make websites. Even maps!

I'm also working on what might make Codecademy's JavaScript classes ring true for more people. You're invited to try Rainy Day Coder and learn JavaScript on rainy nights and weekends! You'll get mail at most twice in a week. You should get the right city automatically - if not, put in your zipcode.

The Man With The Violin

A man sat at a metro station in Washington DC and started to play the violin; it was a cold January morning. He played six Bach pieces for about 45 minutes. During that time, since it was rush hour, it was calculated that thousand of people went through the station, most of them on their way to work.

Three minutes went by and a middle aged man noticed there was musician playing. He slowed his pace and stopped for a few seconds and then hurried up to meet his schedule.

A minute later, the violinist received his first dollar tip: a woman threw the money in the till and without stopping continued to walk.

A few minutes later, someone leaned against the wall to listen to him, but the man looked at his watch and started to walk again. Clearly he was late for work.

The one who paid the most attention was a 3 year old boy. His mother tagged him along, hurried but the kid stopped to look at the violinist. Finally the mother pushed hard and the child continued to walk turning his head all the time. This action was repeated by several other children. All the parents, without exception, forced them to move on.

In the 45 minutes the musician played, only 6 people stopped and stayed for a while. About 20 gave him money but continued to walk their normal pace. He collected $32. When he finished playing and silence took over, no one noticed it. No one applauded, nor was there any recognition.

No one knew this but the violinist was Joshua Bell, one of the best musicians in the world. He played one of the most intricate pieces ever written with a violin worth 3.5 million dollars.

Two days before his playing in the subway, Joshua Bell sold out at a theater in Boston and the seats average $100.

This is a real story. Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of an social experiment about perception, taste and priorities of people. The outlines were: in a commonplace environment at an inappropriate hour: Do we perceive beauty? Do we stop to appreciate it? Do we recognize the talent in an unexpected context?

One of the possible conclusions from this experience could be:

If we do not have a moment to stop and listen to one of the best musicians in the world playing the best music ever written, how many other things are we missing?

Visiting the Reaksmy, Cambodia OLPC XO Project — Kâmpóng Thum, Cambodia


Kâmpóng Thum, Cambodia

Where I stayed
Homestay


I started out in Siem Reap this morning on the Mekong Express Bus. I booked the bus through the hotel reception and was picked up promptly at the appointed time, for transfer to the bus station and to the bus. The Siem Reap to Phnom Penh bus stops in Kampong thom, my destination. I did have to buy a ticket through to Phnom Penh, but it was not expensive ($11.00 US). The bus was clean and had an attendant that gave the information speech in English, French and Khmer. After nearly 3 hours through beautiful rice farming areas, where I saw some evidence of the recent rains and flooding, I arrived in Kampong Thom.

My host, Elaine met me with her driver, Vanny. I was thrilled to finally meet Elaine.
We drove about an hour to Robieng District and Reaksmy village. On the way, Elaine pointed out large tracts that have been clear cut for new industry coming in. She said that the road did not used to be paved. Chinese companies and workers have been working in the area and first paved the road to improve access. Next they began clearing the forest, destroying old forests and displacing wildlife, to make what looks to me like new "factory towns." Elaine thinks that these will be refineries of some kind. I have seen this kind of development in North Vietnam. It benefits the Chinese and their local (in this case, Cambodian) wealthy business partners. The poor rural residents rarely benefit from this type of development. Besides the loss of irreplaceable natural resources, the residents will be facing new types poisons and pollution which will add to the hardships faced by these people who are still some of the poorest in our world.

We arrived in Reaksmy which to me, did not seem near anywhere. I was staying with Elaine in the home her son Dimitri built to be a base for their work to improve education for the children here. I was touched to see the location just next door to the school. It's so close that you can hear the children and their lessons. I did not know very much about this early OLPC XO project, or the non-profit CAMBODIA~p.r.i.d.e., (providing rural innovative digital education) which supports it. http://www.cambodiapride.org/

In 1998 or 1999. Nicholas Negroponte and Bernie Krisher desired to bring education to some of the world\s poorest children. Flying over rural Cambodia in a helicopter, they looked down at Robeing, far from anywhere and ten years ago, before the Chinese paved the road, a 9 hour drive from Phnom Penh. As I am told, they said, "this area looks good," and with a drop of a pin on a map, the lives of hundreds of children from this rice farming village would be forever changed.

In Cambodia, where there are public schools, children are charged tuition. They are charged for books and they are charged for uniforms. Most families cannot afford the fees and most children, and all poor children, are without formal education.

The Elaine and Nicholas Negroponte Primary School in Reaksmy was built in 1999 and all of the Reaksmy village children were welcomed there. Mr. Krisher, now the publisher of the Cambodia Daily also built a school in the same area. The Negropontes, Elaine, Nicholas and their son Dimtri supported the initial efforts and worked on site at the Reaksmy Primary School. Dimitri brought some PCs out to the school, to begin teaching computer skills. In 2005, Elaine founded the non profit organization, CAMBODIA~p.r.i.d.e. to raise funds to help sustain and expand the school programs and community project.

The initial goal was to provide education to these rural children, some of the world's poorest, and to focus upon activities and curriculum that can teach the children to think for themselves. "Give rod, not fish." In the early years, finding and keeping qualified teachers was a challenge, and often the children were coming to school when no teachers were present. It was a struggle to get books, curriculum, and learning materials. The experience at the Reaksmy school led Nicholas to the idea that became One Laptop Per Child. http://one.laptop.org/

Working with MIT Media Lab Professors Seymour Papert and Mitchel Resnick, Nicholas dreamed up the $100 laptop, and in 2007, introduced the first netbook/notebook computer, to the world, with hopes of improving the future the world's poorest children. In just 4 years, portable computing has changed so much, with netbooks, smart phones and tablets flooding the marketplace. The cute little green, rugged XO laptop might not seem so lightweight anymore, against its newer cousins, but for the under-developed rural environment for which it was designed, it is still a very viable option for changing children's lives. Conventional digital equipment will not last very long in hot, wet, humid, sandy environments like Reaksmy.

At first, Dimitri lived and worked in Reaksmy to get things started. I know first hand how our children's paths can change the course of our lives, and thereby the lives of so many others too. Dimitri is still involved of course, but he has a family and work in America and now, his Mom, Elaine, carries the weight of this project. Elaine spends part of every year in Phnom Penh and in Reaksmy. In addition to fundraising, she works tirelessly with the teachers, the children and community residents, to meet whatever needs arise, and those are great.

In late 2007 or early 2008, the Reaksmy project received 500+ XOs and while the keyboard has a Khmer option built in, the children use them with English keyboards in the English program. The primary school computer class was formed welcoming any child who agrees to the attendance requirement. At first the children participating received and owned their own laptop. Those children still in school are now in secondary school and still use them. Because of the finite number of XOs and the large number of children who wish to learn with the XOS, in order to reach more children, the XOs are numbered, shared among different grades and kept in school. Each child is assigned their own laptop number and uses the same laptop each day. Their are 8 classes of 20+- students a day. The students do sometimes take laptops home for out of school homework assignments, rotating by class. The sharing system seems to me to work fine. Be sure to take a look at the photos of the classroom storage station! Those are the original styro-foam packing crates that the laptops arrived in and they have held up very well.

When the children go to secondary school, it is in a school in Robeing that draws from several area primary schools. When the Reaksmy children arrived with XO laptops that others did not have, this did create some problems. Elaine has set up in school library of XOs in the secondary school to address this. Since the graduating children from Reaksmy no longer own their own XO, perhaps the library will need more XOs. Well, that will be a good problem to have!

The XO-1's are quite old, and they are very dirty, due to the hot, dusty, and sandy environment. I was pleased to see that the breakage rate was low and that the children in the 3rd through 6th grades (forms) are quite good with the programs. Their teacher's name is Channa and he is a true gift in that community. He has been with the school for 10 years and has married and made his home in the district in which he works.

I asked if the children are especially excited to join the class with the XOs and if having them perhaps increases school attendance. Elaine explained that yes, attendance is taken seriously and the kids know they have to come in order to participate. But she said that having the XOs to use is quite a normal thing for these kids already. Those children with older siblings or neighbors in Channa's classes have seen all the kids using them and for them, using the laptop is already a very normal part of their school day.

So it is heartbreaking to think that in the secondary schools and high schools in Cambodia, it is not normal to have any exposure to computers at all. What happens to the Reaksmy kids and their computer and Internet skills, when they get to high school? Elaine has tried to address this by acquiring some used Panasonic Toughbooks. These are apparently the laptop of choice that the US Armed Services use in the dusty hot environments in Afghanistan and Iraq, and for some Police and Fire Protection Officers in the US. Elaine has excellent instincts and knows what to do to help. I have learned so much from her. She and Channa have the Toughbooks being used by the 6th graders, for Internet assignments, (when the Internet works), and also available for extra-curricular use during school hours. Anyone can come in and work on them, and I think they are available to the older non primary school students as well. They were always in use and the kids who are not on them, are looking over with interest.

What I saw is that the children love their work with the XOs and the computers. And, they are very good at using them! Be sure to read the Entry following this one where I'm writing about How the Children Use their XOs.

Visiting Reaksmy, was for me a big gift. It was a glimpse back in time to an earlier century. The school has electricity thanks to the efforts of the Negropontes. It comes from a combination of solar and generator power. Outside of the school, where a handwashing facility and protocol has been introduced, and of Elaine’s very modest home, there are few facilities for hygiene. There is very little and only sporadic electricity which is purchased from a man who makes power with a generator and has recently put some lines in, to sell the power. It is rare in the world today to see a place without a TV in every home and with no electricity, where the light of day determines daily schedules. There is no clean potable water, no refrigeration for food storage food, no education for adults about food safety, health or nutrition.

Some of the village traditions are ***********front and heartbreaking to see. There is a traditional medicine woman (Elaine calls her a witch doctor), that ill family members are taken to first. The families cannot afford to go to the health clinic in the nearby town or city, and someone has to be nearly dying before they can be convinced to try it. Then often it is already too late.

Elaine recounts an example that she says is not unusual. Not too long ago, a woman was bitten by a cobra or other type of poisonous snake. There is a westerner nearby who stocks some but not much anti-venom. But the person/family must know which snake caused the bite. Then they must get to the clinic quickly to even have a prayer of living. The family believing that the traditional doctor can help, may be afraid of western medicine and of the expense, which they cannot afford. They brought the woman to the witch doctor, and the young woman, of course, died. The witch doctor told the family that the woman was evil and that’s why the snake bit her and she died. This is not an unusual incident and sadly, it is part of life in Reaksmy.

Everyone who knows me knows me well knows that snakes freak me out. So when I asked how many types of poisonous snakes there are around this village, we started talking about this particular problem. At the next meeting of the English teachers, Elaine brought an idea that the children need a snake identification and preparedness curriculum. She brainstormed about who could visit and teach the children snake education, and said she would speak with the local clinic to try and stock a wider array of anti-venom. I saw that Channa has the 5th and 6th grades already using the Internet in English for research projects and no doubt they can use the Internet to learn about the snakes as well. We talked about the need to educate the “witch doctor’ that people’s lives can be saved. She needs to be encouraged (perhaps paid) to refer the patients to the clinic where they might have a chance to survive a poisonous bite. Education, computers, the Internet: Out here it can make a difference between life and death.

It might take some years to see the effects of their computer classes outside of school, but as the children learn more about the world outside of Reaksmy and Robeing, the hope is that they can improve their own futures if not that of their families. If one child could become a teacher, and one could become a nurse, or doctor, and come back and inspire younger siblings and friends, change, while slow, could come from within.

To me, this is the real story of the Reaksmy XO Laptop project. It is about how the children’s computers, their classes and the Internet have and can affect the entire community. My visit was short, only a few days. Here are some examples of what I saw:

1. The Reaksmy school children are privileged to have school for 8 hours a day. School starts at 7:00AM and goes until 11:00AM. After a long lunch break during the hottest part of the day, the children return from 1:00PM until 5:00PM. The school is safe and welcoming and has toilets and hand-washing facilities (unusual here) that the children and teachers are supposed to help maintain. The children appear happy to be there. But except for the English language and Computer classes who with their dedicated teachers, Virak and Channa, the teacher situation is not great. Often the teachers do not hold class and the children are just outside playing. The Toughbook computers and the Internet, when working are available to the older kids during these times.

2. The first evening, two young men from 11th grade at the high school dropped by Elaine’s house. In order to stay in school, they are living in the Temple Pagoda in the village. They came to ask if Elaine knew a teacher who could tutor them for the high school exam. They know that most students from the area who manage to say in school and take the test don’t pass it. The math and science and language education suffers sorely in this district and in recent years only one student has passed the national test to graduate. They can’t afford to pay a tutor but Elaine will try and arrange something for them.

3. During school a woman came to the class and shyly asked Elaine if she might know why the woman used to be able to read, but now she cannot see well enough. Elaine says that she recently had given another woman some reading glasses and this woman too thought she might be given a pair also. Elaine brought out a handful of drugstore reading glasses to try. They didn’t find the right ones, but you can see the difference that a generous westerner’s presence in town can make.

4. Elaine has a refrigerator (not plugged in) filled with first aid supplies and medicine. Rather than use precious electricity and use the refrigerator for cold storage, Elaine buys ice daily from sweet Mrs. Lang in town. She says if she did not buy ice then Mrs. Lang might not have enough customers to be able to continue to sell it. And then village vendors won’t have an ice source and residents can get sick more often from improper food storage.

5. I met a lovely girl in class whose parents and sister all have AIDS. Her father left the village to go work elsewhere, as is not uncommon. And must have gotten AIDS and brought it home. There is no money for treatment or travel to get it.

6. I met a lovely 16 year old boy named Chua that Elaine has known since he was a child. Chua has a severe and unusual kidney problem that stunted his growth. Elaine has taken him to the Children’s Hospital in Siem Reap for care and has had tele-computer consultation with doctors
in Boston to try and help. The obstacles are so great as Chua’s mother can’t afford to travel or stay with Chua for medical care and she does not ever leave him. At the last visit they learned that sadly, all that could be done at this late stage has been done and I hope that sweet Chua has an easy time when he goes. I received this sad update on Chua from Elaine, December 20, 2011. "Extremely sad news about Chua -- on Saturday he departed for what I hopeis a far better place and one without pain. He was cremated behind the school -- we flew the flag at half mast and the entire primary and JHS went to say goodbye. I have always said that he is the heart and soul of our operation -- not to see him again is very painful for all of us. Renal failure is not a disease to have in a poor country. Not a disease to have anywhere; when dialysis or a kidney transplant is the only option." I am sad for Chua, his mother and the entire community. May his memory be a blessing.

These relationships that Elaine and other westerners working with CAMBODIA~p.r.i.d.e. develop with the local residents are necessary to the success of the project. While working in a remote area in Vietnam, I could not have acquired the solar panels needed to install in the school there, without building relationships in the local community. Today, when Elaine stopped at the Lang's to buy ice, she was speaking with Mr. Lang about when she could take him to Phnom Penh (and presumably pay him) to help her buy a new generator for the Junior High (secondary) School.

Elaine &amp; I spoke about family &amp; cultural obstacles. She is distressed about the widespread ineffective teaching in this District that lessen the chance that more than a few kids will complete high school. The first children who received XO laptops 5 years ago are approaching high school graduation. Unlike others who complete the high school classes in rural Cambodia, these students are computer literate. They know how to use the Internet to learn. I am so impressed to see what even the youngest children are doing with their XOs already. (See my next Entry in this blog). Even if the children here will become rice farmers, they need to learn about the greater world they live in. With their computer skills and access they can learn farm (agricultural) science, about better nutrition and about general, maternal and child health.

The results of Elaine Negroponte's dedication to this community and to this project, are visible already. Through her work, and that of CAMBODIA~p.r.i.d.e., OLPC and the XO project, hopefully even those children that don’t complete their high school exams, will have learned to think and learn. They will have the tools they need to become more successful adults and parents and farmers, run better micro-businesses, and improve their future and that of their families.

Watching the Reaksmy Primary School kids use their XOs, I can hardly believe how much of an impact this earliest XO project has had, and what has been accomplished in one of the poorest and remote locations. How fortunate I feel to have had the opportunity to visit Reaksmy. Thank you Elaine for inviting me and for being a wonderful host!

How do the Reaksmy Children Use the XOs? — Kâmpóng Thum, Cambodia


Kâmpóng Thum, Cambodia

What do the kids do with their XOS?

The Reaksmy Primary School has about 350 children that come to school. About 160 of these children participate in the English computer studies classes in the 3rd to 6th grades. Any child of any age who with their parents agree to and meet the attendance requirements is welcome to participate. It is not unusual to have older children returning to school in the youngest class.

These early XO-1s have a keyboard with Khmer option built in, but the children use them with English keyboards in the English studies Computer skills program. At first the children participating received and owned their own laptop. Those children still in school are now in secondary school and still use them. Because of the finite number of XOs and the large number of children who wish to learn with the XOs, in order to reach more children, the XOs are numbered, shared among different grades and kept in school. Each child is assigned their own laptop number and uses the same laptop each day. There are 8 classes of 20+- students a day. The students do sometimes take laptops home for out of school homework assignments, rotating by class. The sharing system seems to me to work fine.

The school has limited electricity. Many homes in the village have none. It is rare in the world today to see a place where there is not a tv in every home and without electricity, and where the light of day determines daily schedules. Those who an afford it have generators or buy power from someone who sells it. The school building is used during daylight hours and the precious electricity is turned off during the school lunch break and every evening. The children start school at 7:00 AM and finish at 5:00 PM with a 2 hour break fro lunch during the hottest part of the day.

The school’s power supply comes from a combination of solar and generator power, and and more recently from electricity purchased from a local man who has a big generator and has installed some delivery lines. It is fairly new that the school and residents can buy power from overhead lines. The school’s power is purchased with funds from the NGO that the Negropontes started: http://www.cambodiapride.org/

In the classroom, whenever the children use the XOs at their desks, they are plugged into power strips. This is how the XOs are kept charged. The electricity is turned off whenever class is not in session. The dedicated computer teacher, Channa says this procedure works well for them, saves after school power use, and eliminates the necessity to have an after school recharging procedure. Be sure to take a look at the photos of the classroom storage station! Those are the original styrofoam packing crates that the laptops arrived in and they have held up very well.

When the Negropontes began the XO project out here, they arranged for an Internet connection which is beamed by satellite from Thailand and Laos. It is shared with one other western organization working in the same general area. The Internet does not always work and the speed varies from a slow crawl to acceptable. Channa has found that it is not reliable or fast enough to download large files including the new OS builds for the XO when they are released. I had brought working downloads of 11.2.0 on a flash drive and we were both excited to get the new build with some Activities they had not seen, working!

During my visit, someone finally arrived from Siem Reap 4-5 hours away, to diagnose and try and improve things.The school had been waiting for this person already for more than a month. He looked at the satellite, and the young mango tree that provides some shade in the hot schoolyard, and said that the tree limbs were likely blocking the signal. The idea was that if trimming was done immediately while the technician was on site, then they could assess whether in fact that was the problem or whether it was something else indeed. So out came a machete, and a limb trimmer, and first, Elaine's wonderful driver and general helper, Vanny shimmied up the tree to do some trimming. Vanny upset a huge nest of large red ants and got bitten all over and had to stop. So Channa, in his professional "teachers" clothes, white pants and all, climbed the tree to finish the job. Everyone watching on the ground, including me had red ants showered upon us. Oh it is never boring in Reaksmy. I am still not sure that this improved the problem. Perhaps it is a bandwidth issue from the source.

Channa teaches 8 one hour classes each day, 2 each for the 3rd, 4h, 5th and 6th grades or forms. The forms are divided into Level A and Level B, so that the children in one grade who are more proficient can progress and so that those who require more time or assistance won’t get discouraged.

The classroom XOs are all numbered. Each child is assigned an XO by number. Some of the same numbers are shared by children in different grades but each child in each grade uses the same XO every day. This is a clever system for sharing and I hope people from other projects might find my description helpful. So even though 4 to 8 students might be using the XO in class, their work can be saved in the Journal and it can then be accessed the next day so that the children can pick up where they left off.

I saw that all of the children, even the little ones who began he XO program just this year, know how to use the XO appropriately, to open and close Activities and use the proper “Shutdown” method. In the 3B class, the youngest children do not yet know their ABC's. The English language teacher (in the best of worlds) works in tandem with the computer skills class. At the time of my visit, the children had only been introduced to 6 letters of the English alphabet. With these children, Channa chose the GCompriis Activity. It has a 'space invaders" type shooting game with ABC letters (or math) and Channa had the children saying the letters out loud when they appeared on the screen. It was noisy and hard to hear. I had brought a dozen pair of inexpensive cute headphones with me for the classroom and they came in handy. The ABC memory game is a good Activity for this level also. These youngest children might not yet know all of their ABC's but, I was impressed to see that they already know how to use the XOs, and that they were careful to open and close Activities and to use Shutdown to preserve overall battery life.

The 4th graders were learning Scratch. Scratch is probably the most popular activity and I see that Channa has found ways to make it very versatile also. The children were drawing with the paint tools and color. When I arrived, the children had made a video (with audio too) to welcome me using Scratch. I had been wanting to learn Scratch but had not had time to play around with it so on the first day, I sat down with the children and tried to draw my own picture that I could later learn to animate. I figured if a 4th grader can do it...but it was hard and my first effort was embarrassingly primitive in comparison to the kid's work. By learning to draw with Scratch, the children will acquire the skills necessary for using computers for graphic arts. They are learning many related English words every day too. Their skills transfers easily to the Sugar “Paint” Activity and this skill set will transfer to Desktop Publishing on PCs and Macs. I hope that at least some cases, the ease with which these children use computers will open employment doors as the children grow up. How could it not?

The Reaksmy Primary School Project does not stop in Reaksmy, or at the primary school. Prior to the XO program, very few children continued their formal education. The success of the XO computer and English classes has motivated more children from the primary school stay in school. The children needed a secondary school, and so, in 2008-2009 Elaine and Cambodia~p.r.i.d.e. built the ”Junior High School.”

The Junior High School in Robeing has about 280 kids and draws from several area primary schools. When the Reaksmy children arrived with XO laptops that others did not have, this did create some problems. CAMBODIA~p.r.i.d.e. provided generator electricity and the XO library in
the secondary school. Now, they are looking for a technology teacher to live in Robeing and hold a proper class. Since the graduating children from Reaksmy no longer own their own XO, perhaps the library will need more XOs. Well, that will be a good problem to have!

I asked how many kids from the English and computer classes are continuing on to secondary school and to high school, and how does that compare to the statistics of children from classes and schools without the XOs. I don’t have the answer yet but Elaine agrees that this is an important statistic to gather. She will work with Channa on it and let me know.

Not long ago, using their XO skills learned in classes with Channa, the Junior High School students created &amp; “published” a newspaper. They envisioned and produced something like a school newspaper but one that could also bring news to and benefit the community. The first issue, 400 copies sold by the kids around town, quickly sold out.

The kids were very excited with their newspaper report and it was so professional that the Government censors and bureaucracy quickly killed the effort. I heard that for the children to continue reporting the local goings on in town, they would be required to make formal, expensive applications for approval and licenses. The kids loved doing the newspaper. They learned about reporting and writing, and graphic design. There is talk about trying again with a “school report” not called a newspaper. Perhaps they can write a blog about their school and about their Computer classes.

How did the kids manage to produce the first print newspaper in their area? What are the young journalists doing next? How can you use the XOs to teach journalism and produce a newspaper? Scroll below to the Table of Entries and look for my Journalism Entry for the details!

Having the same "technology" teacher for several years brings many advantages. Channa has developed expertise and tools for teaching which include projecting/enlarging the XO screen for teaching. This day, in the 5th grade, the children were learning as a group and once again practicing how to Save their Scratch drawing projects so that they could return to work on them some more on the next day. I can see how important the "teacher" and teaching is. Especially in this culture, it is hard for many kids to learn what to do with the XO, without formal instruction. Again, please check the photos.

On my next day, some of the younger kids had a mystery sound assignment. First Channa introduces the English words and concepts for the lesson. What is a “sound.?” The children were supposed to take the XOs outside around the school and using Scratch, record a “mystery” sound that could be played back in class. The students would then all listen and try and guess what sound was recorded. This active and fun lesson took 2 days, because as it is the English class, the instructions are given almost exclusively in English. sometimes there are communication errors.

The kids (&amp; I with my camera) headed outside with their XOs. I first saw a child drum her hands on a steel drum and record that. Then a few others did that too. They spotted the school bell hanging nearby and made a good racket with that. Next, one child talked an adult with a motor scooter into revving that up to be recorded. The kids loved this Activity and I was impressed that they were doing this in Scratch, not in Record. I enjoyed seeing the XOs being used outside and the children’s smiles and laughter were priceless.

Back in class, Channa discovered that the English word “mystery” had been “lost in translation.” Everyone had such a good time, but now it was time to playback and guess the sounds. Most of the kids had the same sounds so the game was too easy. The children sat around Channa in a circle. He had a sound amplifier and speakers wired so that each XO could be plugged in and the recorded sound played. After each sound, the children all clapped for one another. And then Channa explained the game more clearly. At the end of school, the children in this class would stop by and pick up their XO and take it home, and record just one sound that might be hard for the rest of the class to guess. And the next day, indeed, the class was fun. There were sounds of animals, of cooking, and of scraping and sawing. The kids were very creative and most of the sounds, could have been one of several things and were hard to guess. I can tell you that the children are excited with their XO classes!

I mentioned that the classroom has a few Panasonic "army specs" Toughbooks' donated or bought used and refurbished. And that Cambodia~p.r.i.d.e is always looking for more of these for the older kids. Should your local police or fire department ever be getting rid of old ones, please contact CAMBODIA~p.r.i.d.e. or get in touch with me and I'll steer you to someone that can help! Like the XOs, the Toughbooks seem to be one of the only computers that can withstand the harsh environment, the dirt and sand, wet weather and heat out there.I saw the 5th graders working intently on quite sophisticated Scratch drawing projects to turn into films and games, and the 6th graders using a combination of XOs and Toughbooks for research Assignments using Google in English on the Internet.

On Fridays, there is some free time to choose Activities. Some of the kids were working to perfect their Scratch drawings and others were playing games. Channa also holds a Friday Repair class with the older kids. I had identified some XOs that I thought I might be able to fix and while I was working in the classroom on them, some kids from each class were really interested. I encouraged some of the children and let them help me put disassembled XOs back together. Several boys had never before used a screwdriver. It only took them a second to learn. Frankly, their little fingers and sharp eyes (to find dropped screws) were a big help. I loved working directly with the kids!

I hope this verbal snapshot together with my photos will give you an idea of what an XO project can do in one of the poorest rural places in the world. Even with the many daily challenges that the extreme poverty in this location present, the Reaksmy kids have opportunities, beyond those of their peers who don't have XOs or any type of computer education.

There are many obstacles to success. The extreme poverty of this location presents daily challenges and the financial needs are great. As with other XO projects in poor locations around the globe, the Reaksmy children and their community benefit from the XO project. Even if the children here will become rice farmers, (and someone needs to grow the rice), they need to learn about the greater world they live in. With access to the Internet and the skills to use it, the children will have the tools to learn. They can learn and teach about business, farm (agricultural) science, health and nutrition. They will be better qualified to compete for jobs. Some may continue their studies and become more proficient farmers, or teachers, or doctors. All will have a “head start” to a better future.

Elaine is modest and does not seek publicity for her work. I want to respect her privacy but I must mention that her personal contribution, fundraising for CAMBODIA~p.r.i.d.e, traveling to and living in Cambodia for months at a time, being present and persistent, advising teachers and parents and students of all ages, and always tackling hard problems with determination, has effected great change already. I think that sometimes she does not see the overall accomplishments and progress being made, because there are so many immediate daily needs and challenges. Elaine is one terrific example and role model for the community, as is Channa, the gifted teacher she inspires. No doubt she has inspired others there too, as she has me! How fortunate I feel to have had the opportunity to visit Reaksmy.

Feel free to contact me if you have specific questions about details that might help you with your own XO Projects. I'll try and get the answers for you.

I apologize in advance for any errors or misstatements. The errors are my own and I will be happy to make corrections.

Eshibinga School, Kenya

The Bicycle project and xo s

Early this year, Sandra visited our school. She brought us four more xo laptos and soap. When she left we were happy to see 10 new bicycles arrive at our school. We were told 8 of the bikes were ours. Two were to be sent to another xo project in Uganda. We loved the bikes. Everyone wanted to have one to himself or herself. But it could not happen. We are forty in our class. After consultations we agreed. Teacher jack will keep one.Five of our bikes were to be refurbished so that they could be used as bicycle taxis. In our village we have a booming business called ” Boda Boda” Boda boda is simply bicycle taxi. A bicycle taxi must have a carrier where the passenger sits. Then it needs a strong rider who can carry his weight and that of his passenger. None of us in our class is that strong. Only Washington has some muscles,but he cannot lift a big bunch of bananas.
Anyway, to cut the long story short, we took the bicycles to a bike repairer at Eshibinga market. he fitted them with carriers. Then we got our teacher to talk to some local guys to hire the bikes for a fee. They give us 100 shillings everday to use our bikes.
We intend to use that money to charge our xos. Our school has no electricity. Then we also want to use that money to buy airtime. Airtime is like what we buy to use on the modem which allows us to connect ot the internet. So you see.
We are in business.
I did not mention the other two bikes. We keep them at school. We use them to play and ride round the school. We are now the envey of other kids in our school. We do not only work and use computers. We also ride bicycles. And that is not all. We make some coins too. We love this project. The XOs.
Bye

Hands of Charity XO Project | Kenya

THE CHANGING LIVES OF THE CHILDREN IN BUNGOMA-KENYA DUE TO THE OLPC XO LAPTOP PROJECT

It has a big impact on the children’s behavour;most of them are now more assertive and can articulate their rights vividly.They can present their findings with confidence in their meetings.They have learnt to interact with adults through community outreach programme of HIV/AIDS project.Talents of singing,acting on topics are now being expressed among children in the project.This has really excited the parents and the community at large in Bungoma.Butonge Primary school has received  afew XOs from the small solutions just to start of the sustainability of the project.

It is a big privilege for them to meet with people from outside Africa like the Director of Small Solutions, Sandra Thaxter when she visited the OLPC site in Bungoma,Kenya.The children were so motivated to talk and express themselves as they interacted with our sponsor from the US.The four days of Sandra’s visit was a big time for children in schools and  villages.Perplexed by her skin colour calling her ‘muzungu’, they enjoyed her teaching when she joined Hands of Charity team to teach and interact with them.Our children have a lot of hope.They are so excited to see their teachers and a few of their friends on mountain bikes as they come to teach them.A few children also received bicycles  donated by Small Solutions and friends.This has really changed their attitude towards being in school.They so excited to be school where their are Laptops and they can now access internet to find information and be in contact with the rest of the world.They are now able to access the computers easily because some of the volunteers have been sponsored by Small Solutions to be regular.Hands of Charity in conjunction with Small Solutions are planning to set up Youth Friendly corners in Kenya starting from the Bungoma site.It will help to bring youths together through youth-friendly programmes on the XO computers, we appeal to well wishers and sponsors to donate towards this.Be Part of the team that is transforming children’s lives in Africa by your donation.

Dear google.

Dear google,
We have just read this article using our xo laptop internet. Our teacher has been very busy, But this last three days he has been with us in school. He managed to get us connected to the internet using a cradle point that was given to us by Sandra.
We have just learnt how to google. So we all googled the word xo laptops. And what impressed us all was this article we read about a country close to us that is giving every child a laptop. We just wish Rwanda was Kenya! We have only 8 laptops in our class. How nice it would be if all of us had one each.
My name is Jedida and I am in class six at Eshibinga Primary school.

Rwanda: Project to Distribute 100,000 More Laptops
By Frank Kanyesigye, 6 March 2012
The One Laptop Per Child (OLPC) project is set to receive 100,000 more laptops in a bid to ensure that all 416 administrative sectors in the country have an OLPC-enabled school.
The project that was launched in 2008 by President Paul Kagame has seen about 80,000 laptops distributed in 145 schools countrywide.
“We will receive an additional 100,000 laptops in May 2012,” Nkubito Bakuramutsa, the OLPC Coordinator in the Ministry of Education told The New Times in an interview yesterday.
He explained that the first phase that covered five schools per district was soon coming to an end.
“We are targeting to complete the first phase by the end of March. Now that all districts are covered, we are moving to sectors. We want to ensure that all 416 sectors countrywide have an OLPC enabled school,” he asserted.
Commenting on the rollout of electricity in schools where there is no power, Bakuramutsa said they had an approach that varied depending on the location of the school.
“For schools that are far from the grid, we are working closely with the project in charge of electricity rollout in the Ministry of Infrastructure to install solar energy. Closer to the grid, we are working with district officers and Energy, Water and Sanitation Authority (EWSA) to complete the connection of schools to the national grid,” he explained.
“This is an ongoing process, but for the current phase, we should have all selected OLPC schools connected to power by June 2012. The sector level deployment will see schools connected faster given the experience we developed in the first phase.
Nkubito pointed out that the use of laptops on a daily basis in all schools was going to drastically increase with the current deployment of servers in schools. They will enable all lessons to be covered through digital courses.
OLPC Project has also trained 1,500 teachers and head of schools and is targeting a second round of training which will cover another 1,200.
Whereas government-supported schools are given the custom-made computers free of charge, there is also another arrangement where private schools buy them at a subsidised price of $200 (approx. 120,000).
Speaking to The New Times, Jeanne d’Arc Twambajemariya, the Director of Etoile Rubengera in Karongi District, Western Province, said OLPC had enabled students to learn with ease.
“Our school is not government owned and thus not among the beneficiaries. In partnership with parents, we have purchased 31 laptops,” she said.
“The laptops have improved our pupils’ knowledge in the use of ICT tools, but they are very few compared to the number of children we have. We have written to the OLPC project requesting them to assist us with more laptops if possible.”
According to Theogene Sibomana, the Director of Camp Kigali School, children have learn how to use various applications using laptops.
“They are interested in the use of laptops and this has led us to double the time kids spend on them in school,” he noted.

Eshibinga School, Kenya

Message on XO and use of IT appears at the State Gala April 20th 2012

The president of the republic of Kenya applauded the substantial financial and material support extended to the festivals from Mumias Sugar Company as title sponsors and the National Cohesion and Integration Commission as the thematic sponsors and other sponsors who included Kenyan’s living in diaspora who had sponsored a theme on computers and use of XO laptops and IT in schools. He urged well-wishers to extend similar support to the education sector through such events.
These are words appearing on Kenya government website by the presidential press services. They were spoken during the end of the just concluded drama festivals.
The Kenya National drama festivals came to an end last weekend. Awards and trophies were awarded to winning items and schools. Our theme on xo and use of IT in schools was well represented during the gala, the winners concert and at the State Gala.
State gala refers to a day when all the winning productions in drama are presented before the head of the country. Ie President Mwai Kibaki. Our theme message was well articulated by Booker Academy who won entry to appear at the gala through a solo verse “The Nightmare” as well as a play “Our Daily Bread” Also a kintergarden by the name St. Annes’ Mumias ECD presented a singing game presentation title “Peremende.” Peremende is a Swahili word for candy. It was an artistic dance depicting a child asking for more than a sweet to play with. At the end of the presentation it was clear that the pupils were encouraging for use of e- learning in schools. It had elements of use of IT and Technology to encourage learning in ecd schools.
Apart from the presentation the president of the republic of Kenya did mention and thank sponsors of the xo and other categories in the festival. Here is the full speech of H.E The President of the republic of Kenya
THE PRESIDENT’S SPEECH DURING THE 2012 KENYA NATIONAL DRAMA FESTIVALS STATE GALA AT STATE HOUSE NAIROBI
President Mwai Kibaki has urged Kenyans to join hands in fighting negative ethnicity that divides the country and instead to put every effort towards the realization of a harmonious and united nation. He expressed delight that this year’s national drama festivals had chosen to use ‘enhancing national cohesion and integration’ as the theme of the countrywide competitions.
HE, urged Kenyans to reflect on the importance of promoting a strong sense of nationhood, national cohesion and integration so as to achieve one Kenyan nation.
The President underlined that every Kenyan must always bear in mind their individual responsibility in promoting patriotism and peaceful co-existence among all citizens.
President Kibaki asserted, “It is for this reason that my Government established the National cohesion and Integration Commission. I am confident that the Commission will act firmly in executing its mandate especially as we approach the next general elections.”
The Head of State admitted that the path to the country’s prosperity required every citizen to reflect on how to work within the context of nation’s diverse cultural backgrounds.
The President made the remarks at State House Gardens, Nairobi when the finalists of the recently concluded National Drama Festivals Finalists staged a State Concert in his honour.
President Kibaki observed, “I am particularly encouraged that this year’s Festival theme was on Enhancing National Cohesion and Integration. This theme is especially relevant as it draws attention to our collective responsibility of strengthening our sense of patriotism and nationhood,”
Said the Head of State, “I urge Kenyans to reflect on the important theme of enhancing national cohesion and integration. Let us all embrace the Festival’s valuable message of working together to create a harmonious, one Kenyan Nation.”
During the colorful occasion, the President reiterated the Government’s commitment to harness the talents of the Kenyan youth as an important resource in the development of the country.
He emphasized that the Government was steadfast in its commitment to empower the youth to optimally exploit their rich and abundant talents by providing conducive environment for artists to thrive and exploit their talents.

The President remarked, “As government we are investing resources at the Kenya Talent Academy to ensure that we promote our local artistes. Youth should take advantage of this academy.”
In this regard the Head of State called for a strengthened partnership between the Government, the private and civil society sectors ensure guaranteed success in the preparation of youth to be productive and successful citizens.
The president of the republic of Kenya applauded the substantial financial and material support extended to the festivals from Mumias Sugar Company as title sponsors and the National Cohesion and Integration Commission as the thematic sponsors and other sponsors who included Kenyan’s living in diaspora who had sponsored a theme on computers and use of XO laptops and IT in schools. He urged well-wishers to extend similar support to the education sector through such events.
President Kibaki assured that the Government would continue committing a sizeable amount of resources for development of co-curricular activities adding that this year alone at least Shs 400 million been allocated to support the festivals from the zonal to the national level.
He was delighted that these Government efforts were bearing fruit as evidenced by the phenomenal growth in the number of participants in the music and drama festivals.
The Head of State noted, “This year, the Festival recorded a high number of participants with 10,200 taking part at the national level compared to 9,870 last year. At the lower levels, over 400,000 participated.”
He added, “In recognition of the importance of co-curricular activities, my Government has continued to commit financial and other resources for their development. Since 2003, my Government has continued to promote the development of co-curricular activities in our institutions of learning without levying the parents.”
The President underscored that arts such as music and drama played an important role not only in the intellectual and moral development of learners but also acted as a major source of employment.
He acknowledged, “As a Government, our primary responsibility is to provide services that meet the needs and aspirations of our people. Education is an agent that enables the Government to fulfill this noble responsibility.”
In this regard, the Head of State advocated that the ongoing reforms in the country should align the education sector to the new constitutional dispensation and the country’s development blue print, Vision 2030.
“You should seize this opportunity to come up with appropriate structures that will entrench the performing arts in our education system so that these activities can be fully developed in all corners of our country,” remarked the Head of State.
The Head of State commended the quality of the artistic pieces presented during the concert terming them unique and of very high standards and congratulated the performers for their impressive performance and emerging victorious in their respective categories.
He said, “I also thank the Ministry of Education and all those involved in the Festival for a job well done.”
Speaking during the occasion Education Minister Mutula Kilonzo said a new education policy is being developed to reflect articles 53, 55 and 57 of the constitution.
Mr Kilonzo noted that the bringing together of talents in all educational institutions from the early childhood to university level would harmonize the spirit and letter of the constitution.
Others who spoke included acting Education Permanent Secretary Prof. George Godia and the chairman, Kenya National Drama Festival, Mr. Kahura Chokera.
Among the attendants were Information Minister Samuel Poghisio, Education Assistant Minister Prof. Ayiecho Olweny, acting Head of Public Service and Secretary to Cabinet Mr. Francis Kimemia and the chairman National Cohesion and Integration Commission Mzalendo Kibunjia among other senior government officials.

Keeping Laptops Alive in Haiti

IEEE member and her students help build a solar-powered charging station

By KATHY KOWALENKO 20 April 2012

Reposted from http://theinstitute.ieee.org/benefits/humanitarian-efforts/keeping-laptops-alive-in-haiti

When a primary school in Lascahobas, Haiti, received 400 XO laptops in 2009 from the nation’s Ministry of Education, one important factor was overlooked: how to keep the batteries in the small, rugged, wireless, broadband-ready computers charged. The machines were part of a shipment of 11 000 laptops donated to the country by the nonprofit organization One Laptop Per Child, whose goal is to put entry-level notebooks in the hands of children in developing countries.

But the organization’s involvement ended when the OLPC XO laptops were delivered. It was left to the users to work out such issues as keeping them running and providing Internet access. The school that received the computers—École Fondamentale d’Application Centre d’Appui Pédagogique (EFACAP)—is on Haiti’s national power grid, but keeping the laptops charged was a challenge in a country where electrical service in 2009 averaged about 10 hours a day. Electricity became even harder to come by after the 2010 earthquake hit Haiti, knocking out power to Lascahobas.

Coming to the school’s rescue was IEEE Member Laura Hosman; her students from the Illinois Institute of Technology (IIT), in Chicago; the IEEE Foundation; and other organizations. The machines were brought back to life last year when the group built a solar-powered charging station for the school. The station is the largest single-school photovoltaic laptop-charging system in the world, Hosman says.

PROJECT PROPOSAL
Hosman, an assistant professor of political science, got involved with the project when a former colleague, engineer Bruce Baikie, now president and chief executive officer of Green WiFi—a California nonprofit that provides solar-powered wireless Internet to developing nations—approached her about the problem. The two brainstormed on how to use solar power to charge the laptops.

“People who donate laptops tend not to consider the lack of reliable electricity and Internet connections in developing countries,” Hosman says.

She pitched an idea to IIT for an interdisciplinary, for-credit class that would study how to introduce technology to struggling countries. Developing Technology to Transform Education Throughout Haiti was offered for the first time in the fall of 2010. The course is part of IIT’s Interprofessional Projects Program, which teams 5 to 15 students from sophomore to graduate levels from various disciplines, including architecture, engineering, and humanities, to tackle real-world problems.

Hosman’s academic research focuses on the role of information and communications technology in developing countries. Although not an engineer, she joined IEEE in 2011. “I work very closely with engineers,” she says, “and after I checked its benefits I saw that IEEE was a good organization for me to be involved with.”

Students in that first class—with technical advice from Baikie—designed and engineered a 2.4-kilowatt DC photovoltaic structure. The system, which connects solar panels through a charge controller to storage batteries, can charge 400 laptops at a time, in about 90 minutes.

A US $17 000 grant from the IEEE Foundation helped pay for the materials, tools, and travel for Hosman and 10 students to EFACAP last August to set up 10 photovoltaic panels on the metal roof of one of the school’s buildings. It took them eight days. While there, the students trained the school administrators and maintenance staff on how to keep the system running.

“This project brought me an overwhelming sense of pride in my IIT students,” Hosman says. “They stepped up like I never imagined they could. They formed a cohesive team that accomplished all our goals. It was amazing.”

During last fall’s semester, a new class of 10 students helped set up a solar-powered Internet connection to the school from a backbone tower in the Lascahobas town center. They also installed Wi-Fi hotspots and servers in three buildings across EFACAP’s campus. The students worked with another nonprofit, Inveneo, and its Rural Broadband Initiative to connect the school to a high-speed wireless backbone that the organization was building across Haiti. Based in San Francisco, Inveneo’s mission is to bring affordable, reliable, and sustainable broadband access to developing countries. That work was funded with a $10 000 grant from the Internet Society, another nonprofit that promotes the use of the Net, particularly in impoverished areas of the world.

The students also built a racking system for charging the laptops that the school could replicate using locally available materials. The computers are no longer stacked on top of each other in messy piles while being charged.

“I’m proud of the students for coming up with a rack for less than $1 per laptop,” Hosman says. “No one else has developed a racking solution for charging the laptops at this low a price point before, to my knowledge

The IIT students also explained the project to the school’s teachers, who were on vacation in August, and taught them to set up e-mail accounts and use the Internet. The students plan to keep in touch with the school and check on the system via the Web.

For Hosman, the effort in Haiti showed that students want to get involved with projects that use technology for the benefit of humanity.

“There’s a huge interest among today’s students to have some impact and make the world a better place,” she says.

Ten things about computer use in schools that you don’t want to hear (but I’ll say them anyway) | A World Bank Blog on ICT use in Education

Ten things about computer use in schools that you don't want to hear
Ten things about computer use in schools that you don’t want to hear (but I’ll say them anyway) | A World Bank Blog on ICT use in Education.

The 10 things (9 actually, 10 is left blank) synch pretty nicely with OLPC / Sugar principles, especially:

1. Don’t expect test scores to improve.  What we’ve been doing with kids (Turtle, Physics, Etoys) doesn’t show up on the tests.

2. What happens outside of school is more important than what happens inside of school.  We believe this whole heartedly, but the SoaS keeps failing for kids at home.  At one school, 2 or 3 out of 12 had some luck with SoaS at home.  Second school, one of 12.

3. Not all kids are digital natives.  We are working to reduce the digital divide in Fargo, and while some of the kids in our programs are what Prensky and others might call digital natives, they don’t all wear that label.

From “computing” to “technology” – the “Dumbing Down” of computer literacy


Mentioning Logo along the way, Gary S. Stager has some interesting thoughts on what he sees as the de-evolution of computer literacy and computing in general.

There was once a time in the not so distant path when educators were on the frontiers of scientific reasoning and technological progress. Curriculum was transformed by computing. School computers were used less often to “do school” and more often to do the impossible.

OLPC School Server | George Hunt

Strange power problems with the Fit PC 2

First, I’d like to thank George Hunt for setting up this blog, and letting me post OLPC XS School Server issues here. Thank you.

I have a Fit PC 2 that I’ve used for testing XS 0.6 and XS 0.7 builds. The box is a neat, fanless device that pulls approximately 15 watts on the AC end of the power brick. It does run hot, but a heat sink can solve that problem, and clever mounting with good airflow can solve that problem in the field. I like the fact that this box has a 12V DC input. In tests, we found that the Fit PC2 could support a network of 150 to 175 XOs quite easily.

A few days ago, my unit started to behave strangely. It would not boot up headless. However, if I plugged in a HDMI cable and plugged it into a powered device (such as a TV) on the other end, it would boot up fine!

This wasn’t some accidental BIOS setting that I had changed. It turned out that the power socket that was soldered onto the board had plenty of headroom to wiggle, and given that the power plug would always pull downwards, the continuous pressure had broken off one of the 12V contacts inside. So, it was getting one of the polarities, and perhaps the HDMI cable provided the other path for it to boot, but without the HDMI cable, plugged into a powered device, the box would not boot up.

I pulled it apart, re-soldered the contacts, and filled in the extra headroom with a stack of folded paper (any other suggestions for filler material?). Now, when the plug pulls on the socket, there is no wiggle room, so I hope it will hold.

If you plan on using a Fit PC2 in the field, watch out for this behavior!

A cabochon for your viewing pleasure

From Wikipedia a cabochon is:

A cabochon, from the Middle French caboche (head), is a gemstone which has been shaped and polished as opposed to faceted. The resulting form is usually a convex top with a flat bottom. Cutting en cabochon is usually applied to opaque gems, while faceting is usually applied to transparent stones. Hardness is also taken into account as softer gemstones with a hardness lower than 7 on the Mohs hardness scale are easily scratched, mainly by silicon dioxide in dust and grit. This would quickly make translucent gems unattractive—instead they are polished as cabochons, making the scratches less evident.

A big 'Thank you!" to Bill Tuk for that tip. I've looked at and used cabochons for a while now but I didn't know what these were called. But Bill deserves a bigger "Thank you!" for bringing a bag full of plastic (acrylic?) cabochons to a meeting a while ago. Place the hemispherical cabochon on the XO camera and hold it in place with tape and you have a nice convex magnifier! Of course, Bill tells me (and Mike Lee) that a drop of water works well too. Saliva isn't very clear, so stick with water smiley

Here are some photos from Bill. I am thrilled his tips have made it to the OLPC Learning Club and OLPC Australia!

I’ll be attending Penguicon on April 28, 29.

I’ve never been to Penguicon before; but they invited me and John Scalzi (one of my favorite recent SF authors) to be guests of honor, so how could I possibly say no? I haven’t been to a SF con for decades; much less one crossed with a Linux conference.  I think it should be fun; certainly there are a lot of interesting topics. There are quite a few other fun people attending, including Bruce Schneier, and I’ll get to embarrass myself about Heinlein with Eric Raymond as well as doing a little different take on bufferbloat than my usual talk, more what people can do about it themselves.

Repurposing the OLPC Hand Cranks—Into Mobile Phone Chargers!

Whenever I’ve made a presentation or stood at a display about my team’s work in Haiti, at my university or elsewhere, for an audience of people who are not already working closely with OLPC XOs, I get a question to the effect of: “What happened to the hand cranks?” In fact, it’s almost become a mental game I play once the display or presentation starts: How long until we get the hand crank question?

Every beginning-of-semester, I have my students try them out. After about 5 minutes (max!) they’re done cranking. Usually it’s more like 2 min.

I found a humorous discussion thread on OLPCnews: “Trust me after 5 minutes you want to let someone else have the fun. After 10 minutes you will pay someone to crank it. 4 of us took turns and did the hour. The next day the 2 of us that are wimps couldn’t lift our cranking arm.”

So what to do with the excess ones we had? We decided to repurpose them into cell phone chargers, since that seemed like a more realistic use for them: phones need less charging/use less power, charge on 12 volts, sometimes you just need enough power to make a short call or send a text, and in today’s world, even out to the ends of the earth, where there’s no reception and no powering source, people still own mobile phones! Also, the teachers at the EFACAP school had asked whether they could use the solar system for charging phones, and we felt it was something valuable to add in to the system.

So we purchased some multi-use vehicle chargers with 3 12-volt sockets and a USB charger, (available for a few dollars each on Amazon). We cut the cords on both the chargers and the cranks, and soldered the red wires to the red wires, and the black to the black.

We tested them with our multimeters to make sure they worked, and then the students charged one of their ipods with it, since that was the only device we brought with us that charged with a usb cord. My own cell phone has such a cord, but I hadn’t brought it.

We also wired one of the multi-chargers directly in to the solar system and built a little shelf so that cell phones could be charged on the shelf.

We left the newly repurposed cell-phone charging cranks with the headmaster on our final day there, in December.

Update 4/25/12: I gave a talk yesterday about my team’s work in Haiti. Not even 5 minutes in, someone raises their hand to interrupt my talk with the question about the hand crank. Really!

The OLPC Volunteer Help-Refresh Sprint in Boston — Boston, MA


Boston, MA

I am joining other volunteers in Boston this week, along with some others who are participating remotely. Our goal is to "refresh" the Help Activity for the Sugar OS on the XO.

What does the Help (?) icon on the XO do? Help is the Activity (app) that contains the User Manual. When I received my first day, 2007 G1G1 XO, it arrived in a box with an instruction card to help figure out how to open the laptop. I wondered, now what? Slowly over following the weeks and months, I figured out how to do use the XO to do the things I wanted to do. Many adults asked, “where can we find the manual?” They did not like the answer. No manual? How are we supposed to learn how to use this laptop? Some people quickly gave up. Some fiddled with the Activities and figured it out. And some people volunteered to write a User Manual.

The XO is designed to spark intuitive hands on exploration and learning. It’s based upon education theory called Constructionism.
http://en.wikipedia.org/wiki/Constructi onism_%28learning_theory%29
In theory, experimentation &amp; learning by doing sounds terrific. But in practice, different people have many different learning styles and patience thresholds. For many XO recipients, especially teachers who have never used a computer before, or who have never used one in the classroom, a User Manual may be a necessity to get them started.

In 2008 the OLPC Volunteer Community held it’s first Book Sprint” which resulted in the XO User Manual that is found in the Help Activity. With the many changes and releases to the OS (operating system software), and information sharing from XO projects around the world on how Sugar is being used, the Help Activity needed a revision and expansion. We volunteers believe that this is also a good place to share simple Activity instructions and suggestions for using them.

Last October, 2011 at the San Francisco Volunteer Summit, plans for the Refresh-Help project evolved. And this week in Boston, here we are! The details can be found here: (main wiki link). Adam Holt (OLPC &amp; Haiti), and volunteers Christoph Derndorfer (Vienna), George Hunt (engineering &amp; School Server expert) Mark Battley (Toronto/Kenya), Craig Perue, (Jamaica), Laura de Reynal France/NosyKomba, Harriet V (India). Sandra Thaxter (MA/Kenya) Ed C (Indiana), Sameer (OLPC-SF &amp; Jamaica), and locals, Bernie, Dogie, SJ and others worked and played together at the Cambridge OLPC offices to try and get this project done! I saw that the chief organizer of this project, Caryl Bigenho, was busy helping remotely most of the time. There were other folks around the globe furiously writing and editing too. The main Wiki page with all of the details and participants can be found here: http://wiki.laptop.org/go/Help_Activity _refresh
And, you can join our efforts to complete the job here:
http://wiki.laptop.org/go/Help_Activity _refresh/TOC

The formal Sprint started on Friday April 6 and went through Tuesday, April 10. I arrived from NH on Sunday, after our family holiday celebration. A few volunteers had come in ahead of time. We all worked to re-write chapters for the Help Manual, and to write new ones, and to edit, make suggestions and review each others work.

What else did we do? I missed a picnic on the Charles River, before I arrived. On Sunday night, we had dinner together in Cambridge and a fun evening at historic Grendel's Irish Pub in Harvard Square. http://www.grendelsden.com/ Frisbee and soccer (futbol) in the park, was the Monday afternoon work break. I had never played before. Despite being an obvious liability due to inexperience and "age," my excellent coach, Dogie, made certain that I did not hold my teams back. Everyone had so much fun! Thanks go to Adam for organizing activities that reinforce our teamwork!

Did we get the Manual done? We definitely made progress. At last count I think I heard that 27 chapters were ready to publish. But there is still work to be done. We were all guilty of distraction. There was intense philosophical discussion and sharing of ideas and side projects that various of us are working on. I finally got the "details on Jamaica and Haiti, and I would not have known about Ed's interesting e-publishing efforts, or Harriet's challenges and successes in classrooms in India, without a face to face work sprint. Having OLPC employees like Richard S to troubleshoot hardware/software issues was a bonus. While completing the Manual Refresh is the real goal of this volunteer event, I see equal value in the process and the product!

In Boston, it was wonderful to see some of my Alearn colleagues. It was great to see Sandra agaiin and to hear about her recent very successful trip to Kenya. I especially enjoyed meeting Harriet and learning about her 200 and hopefully growing XO projects for poor children in
India.

Dogie showed me his new program where he can use an XO to control another XO or other computer. I am calling it Open Logmein, as it is like Logmein (proprietary) for the XO. Check the photos, this is wicked cool! I can think of many ways that it can be useful in the field.

Mark Battley had been working the week before on a terrific side project. I am pleased to announce to the OLPC Global Community that 3000 KHan videos will be available for download to play on the XO! Can you believe that Mark convertedso many Khan videos to .ogv files and organized them by subject so that they will play on the XO? This was such an ambitious project and he completed it!

I copied the files onto an external hard drive. Thumb drives will work for this also. To copy all 3000 of the videos you will need about 35 to 40 GB of storage. I tested some of the videos at random. They work fine on a Mac, a PC, and an XO!! They are in English but it is my understanding that the audio files can be translated to other languages. It is an amazing resource, with subjects in math, science, business, health, history and more subjects presented in simple to very advanced clear short videos. I prepared a drive for Elaine N. Next month, these videos will be available to teachers and students with XOs in Cambodia. Mark Battley, YOU ARE MY HERO!

I had time to share and talk strategy with Elaine about Cambodia, and to get her together with Adam. She has made miracles with "her teachers and children" in Cambodia and I want others to know about it and to learn from her experience! I took some time to enjoy spring in Boston and even found a dress for my son's upcoming wedding.

Huge thanks to Adam and Caryl for organizing us, to our hosts in Boston and to everyone who worked on this remotely and in person. We are still working to finish up, but the Help Manual will soon be much improved!
