What's inside the One Laptop Per Child laptop?

The OLPC laptop is reportedly now in full production. Here is a short explanation by Chris Blizzard, OLPC chief software engineer, of key features of the laptop, with a particular focus on its power-saving design. You may also be interested in this BBC fact-file about the laptop, and (thanks to Dick Moore, who sent it as I was writing) this enthusiastic 27/7/2007 article from the Economist - with its sharp conclusion excerpted below the video. If you want to contribute to OLPC, you may also feel like volunteering (or contributing financially).

"Clearly, trying to produce such an extraordinary product as a laptop that is kid-proof and capable of working in jungles, deserts or the bush, miles from the nearest grid connection, and all for the cheapest possible price, has concentrated minds remarkably. The XO offers a lesson for laptop-makers everywhere. In fact, quite a few have gone from ridiculing the OLPC project to trying to emulate or join it. Most notable has been Intel. After first dismissing Mr Negroponte’s laptop as a toy, the chipmaking giant suddenly rushed out a spoiler design of its own for developing countries, fearing it was about to be left out of an emerging market. Called Classmate, Intel’s $225 laptop has failed to impress. Last week Intel admitted defeat tacitly by asking to join the OLPC association. The question now is when can the rest of us get laptops as cheap and clever as the OLPC’s radical design? Judging from the stir the XO has created, the answer is more likely to be months rather than years."

Point-to-point Wi-Fi brings internet to all

 There's been plenty in the media about the beneficial impact of mobile phones on the developing world, and I've occasionally covered this in Fortnightly Mailing. (There is a list of back-links below.)

Paul Marks, in this "subscriber only" article in the New Scientist of 23/6/2007 (reproduced in full here) argues that unless, as in China, there is mandatory mobile coverage of sparsely populated poorer areas, or as in Bangladesh there is a dense population, mobile telephony is only economically viable for the service providers if there are on average enough users for each mobile antenna to justify its costs. Marks reports on an alternative technology called Wi-Fi over Long Distance Networks (WildNets) which can "beam the net to communities hundreds of kilometres away". Wildnets, coupled with the mesh technology being pioneered by One Laptop Per Child, and others, look like a potent way of getting connectivity into all corners of the globe.

For more on WildNets, the technology and approach for which has been developed by Eric Brewer (inventor of the pre-Google Inktomi search algorithm, and now back at the University of California), see this March 2007 article in Forbes, by Michael Zow.

New from Futurelab: 1. Beyond the digital divide; 2. Learning with handheld technologies.

Futurelab is a UK-based and apparently well-resourced educational charity that develops "innovative resources and practices that support new approaches to learning for the 21st century". It spun out of the National Endowment for Science Technology and the Arts a year or two ago.

Two recent publications will be of interest to Fortnightly Mailing readers.

Beyond the digital divide, by Neil Selwyn (whose "Adults Learning @ Home" project I covered in May 2003) and Keri Facer, provides a timely and well referenced review of "why the digital divide remains a complex and entrenched social problem", and calls for "policy responses that go far beyond simply increasing levels of hardware provision and support". Within the report itself, or as a separate document [67 kB PDF], is "Beyond the digital divide, a charter for change", which proposes four entitlements for citizens, and six challenges about the digital divide "which should inform future discussions and action". You can get a flavour of the line taken in the report itself from this interview (?) with Selwyn and Facer from the 18/6/2007 eGovernment Monitor. You can order a free hard copy of the report, or download it as a PDF from the Futurelab web site.

Handhelds - learning with handheld technologies, by Fern Faux, Angela McFarlane, Nel Roche, and Keri Facer, results from school-based research by Bristol University. As well as a directory of nearly 40 handheld projects and resources, the report includes a page of coherent and practical summary recommendations, anddetailed "case reports" from four handheld learning projects:

• The Dudley Handhelds Initiative (~300 students using wifi- and network-connected Palm PDAs);
• Learning2Go Phase 2 - Wolverhampton Local Authority (1000+ students using wifi-connected Fujitsu Siemens Pocket PCs);
• Warren Comprehensive School, London (50+ students, using wifi-connected Dell Axims and Palm Tungsten Cs);
• Stiperstones School, Shropshire (~50 students using Dell Axims with no connectivity).

You can order a free hard copy of the report, or download it as a PDF from the Futurelab web site.

Reading the report I was struck by the fragmentation in the implementation of these kinds of projects: different technology platforms and different content partners; uneven funding; dependence on champions in a Local Authority of school; focus on individual schools rather than on doing things "on an industrial scale". Reports of this kind contain plenty of useful insights; but you cannot help thinking that the One Laptop Per Child project (with its emphasis on technology that has been designed for children, for mass-manufacture, and for genuine ubiquity) illustrates a more realistic and sustainable approach to putting ICT into the hands of children. To the extent that the price of OLPC will fall as the number of units made rises, why shouldn't the developed world throw its lot in with OLPC, if OLPC will let it? And, speculating wildly (naïvely?), if there remains a digital divide in the developed world, you could imagine that OLPC-like devices could play an important part in bridging that as well.

Top Ten Tools - spilling the beans to Jane Hart

Jane Hart has persuaded a lot of people who are active in e-learning - 45 at the last count - to tell her their top ten tools. Mine are shown here. The top 100 tools from all of us are listed here. Firefox, Skype, and a raft of Google services stand out, with Microsoft Office well-cited also. Oh that the same exercise had been conducted every couple of years....

Update - 2/8/2007. Jane has now published a different view of the aggregated data, in the form a personal tool-set and producer's tool-set.

2007 Oxford Internet Survey

Click on image to make it intelligible

Every two years the UK's Oxford Internet Institute does a large scale survey of internet usage in Britain. The full report, which is particularly easy to use on screen, is freely available as an ~80 page PDF [6.3 MB]. Alongside an executive summary and a description of the survey's methodology, the report is in two parts:

• Profiles of users and non-users of the Internet;
• Patterns of Internet use.

Two sections that caught my eye in the "patterns" section were "Creativity and production", and "Learning", and below I reproduce one chart from each section. The first  gives an indication that the overall proportion of users who are actively creating content for the Internet remains quite small and is not growing rapidly. The second highlights the extensive use being made of the Internet for learning, especially informal learning.

The report is most definitely useful, and should be required reading for people in policy and strategy roles. That said, I was left slightly dissatisfied by it. In particular it would have been interesting to know the extent to which users are using "flagship" services like Wikipedia. Secondly, some of the specific "facts" established by the survey did seem to lack basic credibility. For example, if ~90% of Internet users use email it does not feel "right" to me, given the proportion of spam originating outside Britain, that only just under 20% if Internet users have been "contacted by someone over the Internet from a foreign country"; or, given the proportion of spam that involves financial fraud, that under 20% have been "contacted by someone online asking you to provide bank details".

2008 ALT Conference - title announced, and call for Programme Committee members

ALT, for which I work part time, has announced the title Rethinking the digital divide for its 2008 conference, to be held in Leeds, between 8 and 10 September 2008, and issued a call for people to volunteer for membership of the conference programme committee. This is reproduced in full in the continuation post below.

Running a Service Not a System. Terra Incognita posting by Dick Moore.

Substantial and interesting posting by Dick Moore, Director of Technology at Ufi/learndirect (one of the world's few really large-scale providers of on-line learning) about Ufi's e-learning platform and the part played there by open source tools and systems. Also contains plenty of interesting insights into the management of IT, and, in particular, the interplay between in-sourcing and out-sourcing.

Is Web 2.0 a manifesto for anarchism?

David Jennings, whose effusively endorsed book about digital discovery of music will be out soon, has written this a longish and thoughtful post/essay (which he describes as "thinking aloud notes"): Is Web 2.0 a manifesto for anarchism?. (Answer: probably not; but read David's post to find out why.)

"Avant-garde" is the French word for ....
