Leonardo Arduino board shows at Rapid

Educational charity Raspberry Pi Foundation has released a version of Linux optimised for the £25 computer's ARM11 processor, writes Steve Bush.

Linus Torvalds Interview: Linux’s future, Open Source and Raspberry Pi

This year's Millennium Technology Prize, the "Nobel" of the technology world, has for the first time been shared between the two nominees. Stem-cell researcher Shinya Yamanaka and Linus Torvalds, creator of the Linux operating system, will each receive €600,000. Linux underlies Google, Facebook and Amazon, but unlike commercial rivals Windows and Mac OS, Linux is open-source, free, and anyone can improve it. Jacob Aron, of our sister site New Scientist, talked to Torvalds in advance of the prize announcement.
