Something "generative" to try at home with a Wii Controller

Johnny Chung Lee is a graduate student at Carnegie Mellon University's Human-Computer Interaction Institute. Following up on Donald Clark's "$50 whiteboard - honestly", here is Lee's Wii projects page, from which you can find out how to use a Wii Controller (£30 from Amazon, say - you do not need a Wii games console) in various ways, including as the sensor in an interactive white-board. Excerpt:

"As of September 2007, Nintendo has sold over 13 million Wii game consoles. This significantly exceeds the number of Tablet PCs in use today according to even the most generous estimates of Tablet PC sales. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. It contains a 1024x768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz. This significantly out performs any PC "webcam" available today. It also contains a +/-3g 8-bit 3-axis accelerometer also operating at 100Hz and an expansion port for even more capability. These projects are an effort to explore and demonstrate applications that the millions of Wii Remotes in world readily support."

In the continuation post is a lucid video-explanation by Johnny Lee of the white-board project. As an aside, what Lee is doing is a really good example of the "generativity" of the Internet and some of the devices that connect to it  (that is, devices being tinkered with, openly innovated with, and used generally in ways not envisaged by their suppliers, with the Internet used to spread know-how) which  Jonathan Zittrain describes, and defends, in "The Future of the Internet and How to Stop It".

Understanding the Web a.k.a. Web Science - interesting article in a meaty issue of the ALT Newsletter

The Spring 2008 ALT* Newsletter has plenty of meat in it, including:

• a piece by Southampton University's Wendy Hall and Keiran O'Hara (from which a version of the above diagram is taken) discussing Web Science, and reporting in the Web Science Research Initiative;
• Dick Moore of Ufi's In-source, out-source, open-source, right-source - running a service not a system, about the heavyweight infrastructure underpinning learndirect’s learner management system (LMS), learndirect’s service characteristics, and the importance of what Dick calls ‘right sourcing’ in Ufi's technology choices;
• a piece by John Falchi, Chief Program Strategist with IMS, about student textbook use and pricing, and the role of the IMS "Common Cartridge" specification in enabling text book content to be (more cheaply) distributed digitally to students.

Web 2.0 Rights intellectual property toolkit

Here is a new and useful looking "IP Toolkit", part of a newish JISC-funded project that seeks to deal with the following sorts of questions:

• Do IP rights exist in a virtual world and, if so,  who owns them?
• Who owns the rights in works that are a result of collective collaboration?
• What happens if you can’t find the rights holders?
• Can rights be given up, and if so how?
• How can risks associated with content reuse be sensibly managed?

The toolkit provides extensive practical guidance under the following main headings:

1. Basic information about the IP and Web2.0 landscape
2. Practical IP tools for projects engaging with Web2.0
3. Template licences and model releases, covering “Rights in” and “Rights Out”)

What to advise a student about using the Web

Amended 26 October 2008

Towards the end of April I got a call from a Harriet Swain, a freelance journalist who writes an advice column aimed at students for the Guardian Newspaper. Here is what I sent her, with several subsequent helpful additions proposed by readers.

What to advise a student about using the Web

Minor revisions 18, 19, 20 May 2008

Students are like many users of the Web. You are short of time, easily distracted, and you've probably given little thought to how you use the Web.

Here are 8 9 things to do that will make life easier, and your studies more fulfilling.

1. Hone your searching skills. Don't just type a term in to the standard Google search window and hope for the best. Instead improve the efficiency of your searches by doing things like:

• putting quotes round search terms;
• searching within a particular web site using site:URL;
• search the scholarly literature using Google Scholar.

For more on this see http://www.google.com/help/cheatsheet.html.

2. Make use of some of the excellent curated resources on the Internet, for example Intute - http://www.intute.ac.uk/ - a free listing of high quality Web resources for education and research, that is maintained by a network of mainly university-based subject specialists.

3. [20/5/2008 - with thanks to Jay Fogleman] Learn how to use the high-quality online research resources your library has already paid for. These databases and news services are often better for research than public search engines, and provide access to more full text articles. (If your institution's systems are well configured then if you find a subscription-only research resource using Google or Google Scholar to which your institution has subscribed, you should be able to click straight through to it.)

4. Do not expect to find everything you might need on the Internet. Some documents have never been digitised. Others require you to log in to see them. So use your library, and get to know the subject librarians for your discipline. They can be a mine of useful information and support.

5. Discriminate. Much of the Internet is devoted to entertainment of one kind or another, and it is easy to get distracted. Furthermore, plenty of the information resources on the Internet are of variable quality, with Wikipedia being a case in point. Over time your information literacy will improve, and you will become a much better judge of the quality of what you find.

6. Manage your stuff. Create an account on a bookmarking service like del.icio.us - http://del.icio.us/ - or on Nature's Connotea - http://www.connotea.org/, and bookmark things you find for future reference. You'll be able to access this from any device connected to the Internet.

7. Use Firefox as your browser. It is free, and there are a mass of free "addins" for it, for example, excellent spell-checkers in many different languages, tools to make your use of Connotea or del.icio.us easier.

8. Learn how to use RSS feeds. One of the easiest ways to use RSS is to set yourself up with an iGoogle account and install the Google Reader. As with Connotea or Del.icio.us you'll be able to access this from any device connected to the Internet.  Many of the web sites you will need to keep an eye on for your studies have RSS feeds. Subscribe to a web site's feed, and you'll be notified in Google Reader as and when new content is published.

9. Get good at collaborating online. This will assist you in your future working life, as well as in any group-based assignments that you are set. Try out different ways of online collaboration (Facebook, Google Groups, Ning, plain email, SKYPE, wikis, etc etc), and do not assume that the tools provided by your university will necessarily meet your needs. [19/5/2008 - with thanks to Mike Cameron] Be vigilant about how much personal information you reveal online. Once it is "out in the wild" it will be there for ever, visible to future employers, your children, the authorities, and identity thieves. 

For reference, here are Harriet's 29 April 2008 and 14 August 2008 "Art of Being Virtual" pieces; as of 25/10/2008, after much faffing about,  the latter now has an acknowledgement and link to this piece. 

JISC's £5m call: "Institutional Approaches to Curriculum Design"

UK HE Institutions, and FE Institutions with more than 400 full time equivalents of higher education students, are eligible to apply for medium term funding for large-scale course redesign projects. Expect Carol Twigg's National Center for Academic Transformation to get a major boost in traffic, and for good reason. Excerpt:

"JISC invites proposals for projects to review course design and validation processes, and the ways these are supported and informed by technology, in order to transform learning opportunities to address an identified issue or challenge of strategic importance to the institution involved.

Funding of up to £400,000 per project is available with projects expected to last for just under four years. JISC has committed £5 million to this work and expects to funds up to 12 projects. Because of the need for institutions to identity issues or challenges relevant to their own context only one project per institution will be funded. Institutions are encouraged to ensure that the most appropriate bid from their institution is submitted.

JISC is holding a community briefing event where potential bidders will be given information about the background to the call, its objectives and the bidding process. Attendees will also have an opportunity to ask questions about the call. This meeting will take place on 21 May in Birmingham and registration will be open on Friday 2 May 2008.

The deadline for receipt of proposals is no later than 12.00 noon on Thursday 19 June 2008.  Projects should start in 1 September 2008."

Marc Andreessen's "If Microsoft goes fully hostile on Yahoo"

Long and interesting 28 April 2008 piece by Marc Andreessen (who founded Netscape, and is a successful serial entrepreneur in the US), analysing, with the help of expert analysis commissioned (?) by Marc from two corporate attorneys, about how a fully hostile takeover by Microsoft of Yahoo might play out.

Machine translation - a crude comparison - statistical method superior to rules-based?

Last September, just prior to Google switching to its own statistical machine translation system for all the language pairs it offers, I set up a crude comparison between the rules-based and statistical methods used at that time by Google for different language pairs. The crudity stemmed in part from my use of the "round trip" comparison method (defects outlined below), from the use of only one sample text, and from the inherent drawback of comparing translation methods across different language pairs, each of which presents different translation challenges.

Microsoft certified Moodle – Guest Contribution by Jim Farmer

A "Microsoft certified" version of Moodle can be downloaded now from SpikeSource, a venture capital backed US company that aims to make Open Source software "business ready". Available since February 27, 2008,  neither Microsoft or SpikeSource announced the certified version. A representative for SpikeSource said this was a routine extension of the company’s certifications for Microsoft.

Graphene used to create "the world's smallest transistor"

Graphene transistor - image from the University of Manchester

Impression of graphene by Jannik Meyer

Updated 16 April 2012

Within the next 10-15 years, say, Moore's Law will cease to hold for chips made from silicon, because individual transistors will get so small that silicon ceases to function as a semiconductor. Science Daily reports on work published on 17 April 2008 in the peer-reviewed journal Science - abstract - by Ponomarenko, Schedin, Katsnelson, Yang, Hill, Novoselov, and Geim , a team based mainly at the University of Manchester's Centre for Mesoscience and Nanotechnology that proves that transistors one atom thick and 10 atoms wide can be made using graphene, a hexagonal mesh of carbon atoms that is one atom thick. 

For more on graphene, see the frequently updated Wikipedia article, and this 10 April 2007 Scientific American article by JR Minkel, who also comments  in the Scientific American on 18 April 2008 about the "smallest transistor" claim.
