Open Enterprise Interview: Mary Lou Jepsen

Saving Limbu from Linguistic Limbo

There's a fair amount of acrimony flying around the OLPC XO machine at the moment, which is a pity. Because the real story is stuff like this old but still important post that I came across recently:

The development team at OLPC Nepal have been working hard on developing various learning activities for children using the XO. A significant area in which they have been making progress has been in creating activities to help children learn their local dialect.

The first dialect to be setup for use on the XO is Limbu. This is a Tibeto-Burman language spoken by more than 300,000 people in eastern Nepal as well as parts of Myanmar, Bhutan and India.

This is a really exciting development and is a positive counter to concerns that the OLPC project will only serve to homogenise indigenous cultures. In fact, the project may aid the long term preservation and viability of minority dialects and culture which are no longer part of the curriculum in the traditional school teaching models.

I always was a sucker for those Tibeto-Burman languages....

OLPC's Founding CTO Mary Lou Jepsen

OLPC's XO has been much in the headlines recently. If you want to find out it all from someone who knows, there's a good interview on Groklaw with the ex-CTO, Mary Lou Jepsen. And no punches pulled, either:

Q: The world is now very aware of the spoiler role that apparently Intel tried to play. Can you though talk to us about the differences technically between the Classmate and the XO?

Mary Lou Jepsen: Where to start: Classmate is more expensive, consumes 10 times the power, has 1/3 the wifi range, and can't be used outside. Also, the Classmate doesn't use neighboring laptops to extend the reach of the internet via hopping (mesh-networking) like the XO does. So not only is the XO cheaper than the Classmate, the XO requires less infrastructre expenditure for electricity and for internet access. In Peru we can run off of solar during the day and handcrank at night for an additional $25 or so per student – this is one-time expense – the solar panel and the crank will last 10 or perhaps 20 years. Just try running electricity cables up and down the Peruvian Andes for that cost while making sure it's environmentally clean energy. The Classmate isn't as durable as the XO, and its screen is about 30% smaller, the batteries are the type that can explode and only last 1-2 years and can't be removed by the user and harm the environment. The batteries are expensive to replace: $30-40 per replacement. The XO batteries last for 5 years and cost less than $10 to replace. Finally, the XO is the greenest laptop ever made, the Classmate isn't – this matters a great deal when one proposes to put millions of them in the developing world.

OLPC XO-1 Exposed

The OLPC XO-1 project has been something of a roller-coaster ride. Widely praised when it launched, and then progressively pooh-poohed (including by me) as the wrong solution, more recently praised once more for the execution of the underlying idea, and finally put in doubt following Intel's rather suspect ship-jumping.

For what it's worth, in the light of the reality, rather the idea, I've changed my view: the OLPC XO-1 really seems to serve its intended audience well, and to be a well-desinged bit of kit. Confirming that is this splendid deconstruction by arch-hacker Andrew "bunnie" Huang , founder of the similarly-spirited Chumby project:

If I were to make one general comment about the OLPC XO-1, it’s that its mechanical design is brilliant. It’s a fairly clean-sheet redesign of traditional notebook PC mechanics around the goal of survivability, serviceability, and robustness (then again, I’ve never taken apart any of the ruggedized notebooks out there). When closed up for “travel”, all the ports are covered, and the cooling system is extremely simple so it should survive in dusty and dirty environments. Significantly, the port coverings aren’t done with rubberized end caps that you can lose or forget to put on–they are done using the wifi antennae, and the basic design causes the user to swivel them back to cover the ports when they are packing up the laptop to go. That’s thoughtful design.

Whatever the Question, the Answer's GNU/Linux

It's interesting that whenever people try to come up with low-cost machines for developing countries, the answer is GNU/Linux. The OLPC/XO is the best-known example, but here's another one:

Rather than one inexpensive laptop per child, the answer being presented is a somewhat more powerful computer, with zero maintenance or moving parts, which can be shared by a number of children running free and open source software.

Of course, it's pretty obvious why: the cost of software is zero, which means there's no money there wasted on fat cats in Western countries. But there's another interesting angle:

Perhaps the oddest technical feature of the tablet-style PC is the fact that it runs an ARM-based RISC CPU, the Freescale i.mx31. The key reason for choosing this RISC CPU over a conventional x86 Intel or AMD processor was battery life. Morgan explained that this CPU's power envelope of just 3.5 watts made an 8-hour use possible. The other key reason was that this particular chip had strong video and graphics capabilities, which would be needed to show videos and animations in a classroom environment.

The downside is that it does not run the vast amount of x86 software out there.

The operating system is a cut down version of Debian Linux, recompiled for the ARM architecture, complete with most of the office and communications software expected in a GNU/Linux system.

Oh look: there's that wide platform support again: is this turning into one of open source's best-kept secrets? (Via Linux Today).

Oh, Well Done, Microsoft

Look: little Johnny Microsoft is doing *ever* so well in his plucky attempt to catch up with that clever GNU/Linux chap:

Microsoft Corp has made progress in getting its Windows software to work on a low-cost laptop computer for poor children that currently runs on rival Linux software, an executive said on Thursday.

The world's largest software company is now working to adapt a basic version of Windows XP so it is compatible with the nonprofit One Laptop per Child Foundation's small green-and-white XO laptop.

"We're spending a nontrivial amount of money on it," Microsoft Corporate Vice President Will Poole said in an interview on Thursday."

But be warned:

"We remain hopeful with our progress to date, we still have significant work ahead to finalize our analysis and testing processes," he said. "At the end of the day, there's no guarantees."

So, just remember that: when you're dealing with Windows XP, there are no guarantees. Unlike with GNU/Linux, of course, since it runs rather nicely on the XO already. Now, which would *you* rather have?
