There is no known attack on ECC using quantum computers.

This should not have been modded up, because it is blatantly false. The security of ECC relies on the presumed hardness of the discrete logarithm problem (in elliptic curves over finite fields). But Shor's algorithm can solve the discrete logarithm problem in ANY finite group (assuming you have an efficient way of operating on the group elements).

C++0xB is a cleverer name since it can be interpreted in two ways:
1) Since C++0x wasn't completed in 200x as expected, it's time for plan B, namely C++0xB.
2) 0xB represents 11, since 0x is the prefix for hexadecimal in C++. And so C++0xB still literally means the version finalised in 2011.

How To Enter Equations Quickly In Class? 823

AdmiralXyz writes "I'm a university student, and I like to take notes on my (non-tablet) computer whenever possible, so it's easier to sort, categorize, and search through them later. Trouble is, I'm going into higher and higher math classes, and typing "f_X(x) = integral(-infinity, infinity, f(x,y) dy)" just isn't cutting it anymore: I need a way to get real-looking equations into my notes. I'm not particular about the details, the only requirement is that I need to keep up with the lecture, so it has to be fast, fast, fast. Straight LaTeX is way too slow, and Microsoft's Equation Editor isn't even worth mentioning. The platform is not a concern (I'm on a MacBook Pro and can run either Windows or Ubuntu in a virtual box if need be), but the less of a hit to battery life, the better. I've looked at several dedicated equation editing programs, but none of them, or their reviews, make any mention of speed. I've even thought about investing in a low-end Wacom tablet (does anyone know if there are ultra-cheap graphics tablets designed for non-artists?), but I figured I'd see if anyone at Slashdot has a better solution."

Judge Suppresses Report On Voting Systems 192

Irvu writes "A New Jersey Superior Court Judge has prohibited the release of an analysis conducted on the Sequoia AVC Advantage voting system. This report arose out of a lawsuit challenging on constitutional grounds the use of these systems. The study was conducted by Andrew Appel on behalf of the plaintiffs, after the judge in the case ordered the company to permit it. That same judge has now withheld it indefinitely from the public record on a verbal order."

Apple TV to be a Centrally Controlled P2P Network? 165

Posted by Zonk on Friday February 16, 2007 @03:04PM from the lean-on-your-neighbors dept.

Rolgar writes "PBS' Bob Cringely theorizes that since the Apple TV will be an always-on device with a 40GB hard drive, Apple may move to content distribution via a P2P network. The ISPs will incur higher bandwidth locally, possibly lose some subscribers to cable TV, but have fewer costs through the Tier II Internet backbone providers. Bob also expects that Google will be involved with their fiber network and advertising expertise, and my hope is that they'll bundle in YouTube content as well. The article suspects that they won't get around to announcing the full details of this plan until they hit a half million units or more, and that this Apple and Google pairing will become the equivalent of a cable TV provider with almost none of the infrastructure costs. Eventually, he hopes, we'll see a real HD revolution from Apple and Google for this service." If Apple rolled something like this out to the service, would you bite on it? What would it take you to move to this over Tivo or MythTV?
