+ - First inkjet-printed graphene computer circuit is ->

Submitted by

MrSeb writes "You can add another crazy characteristic to graphene’s ever-expanding list of “wonder material” properties: It can now be used to create flexible, transparent thin-film transistors... using an inkjet printer. The discovery comes from researchers at the University of Cambridge, UK, who were trying to ameliorate the lackluster performance of existing inkjet-printed electronics. It’s already possible to print standard CMOS transistors using different ferroelectric polymer inks, but the resultant circuit is so slow that it can’t actually function as a computer. If graphene could replace or augment the interconnects or transistors, these circuits would be a lot faster — and that’s what these Cambridge engineers have done. Furthermore, if you didn't think that was cool enough, the graphene-based ink that they've developed is transparent, too."

+ - New wave of botnets on the horizon->

Submitted by
Trimegistus
Trimegistus writes "The recent breakup of the ChangeDNS botnet which infected more than 4 million computers and was under the control of a single ring of criminals raised a new set of concerns. The biggest effect of the commoditization of botnet tools and other computer security exploits might be a new wave of major botnet attacks, driven by people who simply buy their malware from the equivalent of an app store—or who rent it as a service."

harrymcc writes "I recently got to visit Facebook's state-of-the-art, hyper-efficient data center in Prineville, Oregon. It's a 333,400-foot facility with tens of thousands of servers--Facebook doesn't like to say precisely how many--yet it's operated by a grand total of 55 people, about half of whom are involved in its security. I took photos of servers, the extensive space devoted to cooling them, the gnome garden (who knew Facebook had a gnome garden?), and more."

+ - CEO shows his @$$ on ex-employee's blog->

Submitted by Anonymous Coward
An anonymous reader writes "I used to keep a blog about my terrible job. After I was fired and denied my commission check, I publicized the blog. This created a huge buzz, locally, which eventually got back to the CEO, who left me a nice, eloquently-written response (on the blog), along with his phone number, and personal contact information, FOR THE ENTIRE WORLD TO SEE. This sent the blog viral, and I'm now receiving between 8,000, and 10,000 hits a day. Total insanity. I thought fellow slashdotters would enjoy it."

+ - Superluminal Neutrinos Compatible With Information->

Submitted by mhelander
mhelander (1307061) writes "Dear Slashdot, the recent repeated measurements of Faster-Than-Light neutrinos seem incompatible with the model of Einstein. My question to the Slashdot community is if such measurements should also be considered incompatible with information theory? My own analysis, available in draft form at http://relevancetheory.blogspot.com/2011/11/general-theory-of-relevance.html seems surprisingly to indicate that information theory does not exclude such a possibility. I would greatly appreciate discussion with the Slashdot community on this topic to examine the consistency of my conclusion that information theory does not exclude the possibility of superluminal neutrinos and by extension that superluminal motion is not necessarily in complete conflict with the model of Einstein."
