twitter writes "Recent and controversial benchmarks for Windows 7 leave an important question unanswered: 'Is it faster than GNU/Linux?' Here, at last, is a benchmark that pits Ubuntu, Vista and Windows 7 against each other on the same modern hardware. From install time to GUI efficiency, Ubuntu beats Windows and is often twice as fast. Where Windows 7 is competitive, the difference is something the average user would not notice. The average GNU/Linux user is now getting better absolute performance from their computer as well as better value than the average Windows user."

Science News has a fascinating look at an under-appreciated corner of the career of Florence Nightingale — as an innovator in the use of statistical graphics to argue for social change. Nightingale returned from the Crimean War a heroine in the eyes of the British citizenry, for the soldiers' lives she had saved. But she came to appreciate that the way to save far more lives was to reform attitudes in the military about sanitation. Under the tutelage of William Farr, who had just invented the field of medical statistics, she compiled overwhelming evidence (in the form of an 830-page report) of the need for change. "As impressive as her statistics were, Nightingale worried that Queen Victoria's eyes would glaze over as she scanned the tables. So Nightingale devised clever ways of presenting the information in charts. Statistics had been presented using graphics only a few times previously, and perhaps never to persuade people of the need for social change."
