Weekend and holiday effects are a bit more obvious, and it's a bit like being able to see the daily, weekly, monthly and yearly closes all...

Under the Hood of App Inventor for Android -- regular readers know I'm a big fan of visual programming language Scratch, and apparently Google are too. They've got twelve university classes testing App Inventor for Android, a visual connect-the-bits programming environment for Android. University classes probably because one of the co-creators is Hal Abelson, coauthor of the definitive programming...

Making Government Transparent Using R

By James Turner
July 14, 2009

With Open Source now considered an accepted part of the software industry, some people are starting to wonder if we can't bring the same degree of openness and innovation into government. Danese Cooper, who is actively involved in the open source community through her work with the Open Source Initiative and Apache, as well as working as an R wonk for Revolution Computing, would love to see the government become more open. Part of that openness is being able to access and interpret the mass of data that the government collects, something Cooper thinks R would be a great tool for. She'll be talking about R and Open Government at O'Reilly's Open Source Conference, OSCON.

Viral Epidemics Poised to go Mobile -- Albert-Laszlo Barabasi (author of Linked: How Everything Is Connected To Everything Else) modelled mobile phone virus epidemiology for NSF and concluded that (in accordance with experience) no single OS has critical mass for viruses to break-out. I wonder: will Android or iPhone reach that point first? (via ACM TechNews) Socrata -- formerly...

The Solid State Storage Revolution: If you haven't seen it, I recommend you watch Andy Bechtolsheim's keynote at the recent Mysqlconf.

Responding to Morozov on Twitter's "Power to Misinform"

By Timothy M. O'Brien
April 26, 2009

In Foreign Policy, Evgeny Morozov writes about Twitters power to misinform in the context of the emerging Swine Flu crisis. In his article he brings up concerns about the use of Twitter to spread misinformation and makes some broad generalizations about the motivations of the average Twitter. In this article, I response to some of the things Morozov has to say about the validity of analyzing Twitter trends.
