This 18 minute TED-X talk by David MacKay deserves attention, despite the difficulty you may have in making out some of what was on screen during the talk.
For the underpinning analysis, go to MacKay's remarkable book/website Sustainable Energy - Without the Hot Air.

This week's New Scientist has an interesting interview - login required - with Linus Torvalds, the initiator and leading light in the creation of the Linux operating system that powers the Web and sits at the heart of Android.
Torvalds makes a couple of interesting points - emphasis added below - about the Raspberry Pi and about why open source software matters so much for the coming "Internet of things".
Q. What about Raspberry Pi, a Linux-based computer costing $25? Will that change things?
A. What's interesting about Raspberry Pi is that it's so cheap almost anybody can buy it as a throwaway - throwaway in the very good sense that it could get people involved in computers who otherwise wouldn't be. For a lot of people, it will be a toy gathering dust, but if 1 per cent of the people who buy it are introduced to computers and embedded programs, that's huge. It can get people into the mindset of using a computer to do everyday jobs that even five years ago it would have been ridiculous to use a computer for because they were big and expensive. With Pi, you can say, I wouldn't use a real computer for this, but maybe it can control my water heater.
Q. Is a future where homes are run by computer only possible with open source? If Raspberry Pi had to run Windows, would it be too expensive?
A. Yes. Open source is a very powerful way to try something new. The thing about trying something new is that 999 out of 1000 cases will fail. Having this, easy entry into trying something new means having one case where it works is very good. Raspberry Pi is a way to allow experimentation on an even smaller scale because you have the hardware, too. When you aim for that price you can't afford not to use a free, open operating system.

Udacity is developing quickly, with two announcements last week that signal the direction it is taking.
Firstly five new "premiere" courses have been added:
All start on 25 June.
Secondly, in partnership with Pearson's testing company VUE, students will be able to sit secure exams at one of 4000 centers worldwide in 165+ countries, the aim being to make success on a Udacity course count towards a qualification that is recognised by employers.
Note that in May 2012 VUE acquired another big (or bigger) testing company Certiport (which has 12,000 authorised testing centres and which runs the certification processes for industry-accredited training programmes such as those provided by Adobe, Autodesk, CompTIA, and Microsoft). So expect the number of centres where Udacity students can get tested to increase further.
According to Udacity's announcement "There will be a nominal fee required to take the exams, which will offset the cost of physical testing centers and staff."
The tie-up is a good example of deciding sensibly when to do things yourself (i.e. making and running courses), and when to work with others who already have capability alongside a very large scale operation (as in Pearson's case), that you can draw upon. On the other hand, if (and that is a big if) a way could be found to deliver uncheatable tests straight to a learner's desktop, then that would strip out the additional layer of complexity that running tests through someone else's systems and facilities will inevitably involve.
PS - I am gradually making progress in and enjoying my Udacity CS101 "introduction to computer science" course. I will report on this soon, drawing out the design and other differences between CS101 and the prototype AI course I did last year. In other news, I'm really pleased to learn that Riga-based Gundega Dekena (who wrote this Fortnightly Mailing guest contribution that compares three of last year's "Stanford" online computer science courses) is now working for Udacity as the course manager for the Programming a Robotic Car course.

Between January and May 2012 I had the luck to have worked with Adrian Perry, Clive Shepherd, and Dick Moore researching and writing the report Scaling up - Achieving a breakthrough in adult learning with technology [PDF, 53 pages] for the Ufi Charitable Trust. The Trust will be open for Stage 1 applications for funding on 2 July 2012.

Here in one place are some largely unfiltered snippets from my FriendFeed "stream" (about 2 posts per day) for the period 19 May to 3 June 2012.

System Upgrade - a vision for technology enhanced learning in UK education
Today I attended the launch of the Technology Enhanced Learning Research Programme's "System Upgrade" report, which summarises the overall findings of the programme and offers recommendations for future strategy. [The 17 minute documentary from the 6 November 2012 final public meeting of the TEL programme is here.]
The report has been written by TEL director Richard Noss and a team drawn from those who led the different strands of the £12m programme over the last 5 years.
It is written in layperson's terms, with two or three coherently structured pages, with examples, for each of the following 12 recommendations:
Here are three links to snazzily designed materials:
Printed copies of the PDFs can be ordered from the TEL programme.
[Disclosure: for the last few years I was a member of the Advisory Group for the Programme].
