This version of the SVG-based vector graphics editor brings improved performance and tons of new features, including: timed autosave, Spiro splines, auto-smooth nodes, Eraser tool, new modes in Tweak tool, snapping options toolbar & greater snapping abilities, new live path effects (including Envelope), over 200 preset SVG filters, new Cairo-based PS and EPS export, spell checker, many new extensions, optimized SVG code options, and much more. Additionally, it would be wrong to not mention the hundreds of bug fixes. Check out the full release notes for more information about what has changed, enjoy the screenshots, or just jump right to downloading your package for Windows, Linux, or Mac OS X." We've been following the progress of Inkscape for years (2006, 2005, 2004).

austinpoet writes in with a blog post debunking the theory we discussed a few days back that scientists' beer consumption is linearly correlated with the quality of their work. Chris Mack, Gentleman Scientist and beer drinker, has analyzed the paper and found it is severely flawed. From his analysis: "The discovered linear relationship between beer consumption and scientific output had a correlation coefficient (R-squared) of only about 0.5 — not very high by my standards, though I suspect many biologists would be happy to get one that high in their work... Thus, the entire study came down to only one conclusion: the five worst ornithologists in the Czech Republic drank a lot of beer."

antipeon alerts us to a presidential preference survey, done in late February and early March, indicating that Obama and McCain lead among IT workers with 29% each. Clinton follows with 13%, just ahead of Huckabee (11%) and Ron Paul (9%). The Computing Technology Industry Association commissioned the poll, and the article notes that this trade group claims the population of IT workers is four times as large as the Bureau of Labor Statistics thinks it is — the better to make a voting block whose views must be attended to.
