Storing all of our culture with perpetual access for everyone.
To store 720p AND 1080p copies of every movie and tv-show listed on IMDB would probably take something like 10 PB. That would likely cover dubbed soundtracks and subtitles as well.
And at Sun's prices, that'd be about 10 million dollars for a single copy (not including data center costs) stored in 21 racks.
Add in all the books ever written, music and news papers published, what are we looking at? 50 PB for a full copy? Obviously you'd need redundant storage placed on various continents, and you'd expect to replace the hardware every once in a while, but what is our entire cultural history worth to us as a civilization? A billion dollars a year? Two? Keep in mind, it shouldn't just be the US or the EU funding this, it should be everyone.
Make it a requirement for companies that if they want copyrights on their works, they have to submit it unencumbered to the storage facility. That way there can be no excuses from the companies, that they don't have $work in production any more, as it'd be easy to sell access to a particular work. And if they can't submit it for whatever reason? Copyright expires on that particular work. That'd certainly get their asses in gear to get their entire back catalogue digitized.

Linux vulnerable to null pointer dereference exploits.
And yet another reminder that you should always check pointers for NULL before dereferencing them. Also, did you know that gcc disables "unnecessary" null pointer checks with -O2? Use -fno-delete-null-pointer-checks to prevent this from happening. To quote man gcc: "The compiler assumes that dereferencing a null pointer would have halted the program. If a pointer is checked after it has already been dereferenced, it cannot be null. In some environments, this assumption is not true, and programs can safely dereference null pointers." It is sometimes possible to have 0x00000000 mapped to userspace (in this case by way of a kernel module and a setuid pulseaudio), thus preventing the segmentation fault that would usually occur when remapping 0x00000000 to your own code.More details here (in German, but very informative): http://www.heise.de/newsticker/Root-Exploit-fuer-Linux-Kernel-veroeffentlicht--/meldung/142171 and here for the exploit itself: http://lists.grok.org.uk/pipermail/full-disclosure/2009-July/069714.html and more explanation here: http://isc.sans.org/diary.html?storyid=6820

NYCResistor & U.S. Hackerspaces Featured on Wired.com

Dylan Tweney wrote a fantastic article on Wired.com about hackerspaces in the US. NYCResistor was profiled along with Hack DC and Noisebridge. A fun and interesting read…
While many movements begin in obscurity, hackers are unanimous about the birth of U.S. hacker spaces: August, 2007 when U.S. hackers Bre Pettis, Nicholas Farr, Mitch Altman and others visited Germany on a geeky field trip called Hackers on a Plane.
“It’s almost a Fight Club for nerds,” says Nick Bilton of his hacker space, NYC Resistor in Brooklyn, New York…
