The submission by Microsoft of twenty thousand lines of code to the Kernel has, predictably, caused many an eyebrow to arch. The phrase "beware Greeks bearing gifts" comes swiftly to mind. I checked the press release. I also checked the calendar just to make sure I hadn't fallen into a wormhole and emerged back on April Fools Day. I hadn't. That reaction was probably replicated right across the free software community. Given Microsoft's track record it's hardly surprising. Perhaps what was more interesting was Linus Torvalds' reaction. After all, this is not an inconsequential flame war about using Gnome or KDE.
