Visualising Time Series Data in Tweets — builds sparklines from Twitter Data tweets.
GPL Inadequate for Open Source Voting Software — the GPL prohibits “additional restrictions”, but the US Government has requirements for its voting software that fall into that category. An interesting read. The solution will be a new open source license (sigh) but one that meets their specific and real needs. (via Glyn Moody)
SatScan — free software that analyzes spatial, temporal and space-time data using the spatial, temporal, or space-time scan statistics. It is designed for any of the following interrelated purposes: Perform geographical surveillance of disease, to detect spatial or space-time disease clusters, and to see if they are statistically significant; Test whether a disease is randomly distributed over space, over time or over space and time; Evaluate the statistical significance of disease cluster alarms; Perform repeated time-periodic disease surveillance for early detection of disease outbreaks.

Who Is Going To Build The New Public Services? — a thoughtful exploration of the possibilities and challenges of third parties building public software systems. There’s a lot of talk of “just put up the data and we’ll build the apps” but I think this is a more substantial consideration of which apps can be built by whom.
Quake 3 for Android — kiss the weekend goodbye, NexusOne owners! My theory is that no platform has “made it” until a first person shooter has been ported to it. (via BoingBoing)
Graph Mining — slides and reading list from seminar series at UCSB on different aspects of mining graphs. Relevant because, obviously, social networks are one such graph to be mined.
Treadmill Desk — I want one. Staying fit while working at a sedentary job is important but not easy. I tried to type while using a stepper, but that’s just a recipe for incomprehensible typing fail. (via BoingBoing)

OSOR.eu — The OSOR is a platform where public administrations can exchange information and experiences and collaborate in developing free and open source software. The platform has managed to bring together more than 2000 such open source software applications in just sixteen months after its launch. (via EUPractice and vikram_nz on Twitter)
Inside Glitch — writeup of behind-the-scenes during the development of the game Glitch, the new project from Stewart Butterfield, Cal Henderson, Eric Costello, and Serguei Mourachov. The historical details themselves are banal, but what’s interesting is how the reporter got access: “I’ll let you determine when the piece runs (but not editorial control over what goes in it), and in return I get to meet regularly with you and you tell me all.” It’s analogous to the Newsweek tell-alls that come out after the election. (via Waxy)
Open Clip Art — archive of public domain-contributed clip art. (via Mark Osbourne)
How To Split Up The US — clique analysis from 210 million public Facebook profiles. Some of these clusters are intuitive, like the old south, but there’s some surprises too, like Missouri, Louisiana and Arkansas having closer ties to Texas than Georgia. To make sense of the patterns I’m seeing, I’ve marked and labeled the clusters, and added some notes about the properties they have in common.
