One of the most frequently raised arguments against renewable power sources is that they can only supply a low percentage of the total power because the unpredictability can unstabilize the grid. Spain seem to have proved the contrary: In the last 3 days, the wind power generation records with respect the total demand were beat two times, (in special conditions: a very windy weekend, during nigth): 45% day 5 and 53% (spanish) last night. There was no unstability. How it was done? There's a Control Center that processes meteorologic data from the whole country and predicts, with high certainty, the wind and solar power that will be generated, allowing a stable integration of all the renewable power. You can see a graphic of the record here.

Here is LWN's eleventh annual timeline of significant events in the Linux and free software world for the year. As always, 2008 proved to be an interesting year, with great progress in useful software that made our systems better. Of course, there were some of the usual conflicts--patent woes, project politics, and arguments over freedom--but overall, the pace of free software progress stayed on its upwardly increasing trend. 2008 was a year that saw the end of SCO--or not--the rise of Linux-based "netbooks", multiple excellent distribution releases, more phones and embedded devices based on Linux, as well as major releases of software we will be using for years (X.org, Python, KDE, ...).
