US ISPs Announce Anti-Child-Porn Agreement 613

An anonymous reader writes "It seems that ISPs have gathered together with 45 attorney generals and the National Center for Missing and Exploited Children (NCMEC) to form an agreement to crush child pornography. What does that mean? Probably the same as it meant for RoadRunner, Sprint, AT&T and Verizon customers — the end of the newsgroups." Here's the back-patting press-release from the various parties who signed on (the National Cable & Telecommunications Association, the National Center for Missing and Exploited Children, and the National Association of Attorneys General), though the actual text of the agreement does not seem to have been made public.

Schneier, UW Team Show Flaw In TrueCrypt Deniability 225

An anonymous reader writes "Bruce Schneier and colleagues from the University of Washington have figured out a way to break the deniability of TrueCrypt 5.1a's hidden files. What about the spanking-new TrueCrypt 6? Schneier says that 'The new version will definitely close some of the leakages, but it's unlikely that it closed all of them.' Meanwhile, PC World is reporting that the problems Schneier and colleagues found are bigger than just TrueCrypt. Among their discoveries: Word auto-saves the contents of encrypted files to the unencrypted portions of your disk, and this problem should apply to all non-full disk encryption software. Their research paper will appear at Usenix HotSec '08."

Liquid Mirror Telescopes Set For Magnetic Upgrade 64

from the calm-the-hubble-hubbub dept.
KentuckyFC writes "Liquid mirror telescopes start life as a puddle of mercury in a bowl. Set the bowl spinning and the mercury spreads out in a thin film giving the surface an almost perfect mirror finish. But these telescopes have two important limitations. First, they can only point straight up since tilting the mirror spills the mercury. And second, they cannot be made adaptive to correct for any blurring introduced by the Earth's atmosphere. But liquid mirror telescopes look set for an upgrade thanks to the work of a group of Canadian researchers. Their technique is to change the shape of the liquid mirror using powerful electromagnets. They use a ferromagnetic fluid of iron nanoparticles in oil instead of mercury which is too dense to be easily manipulated in this way. The work is just proof of principle at this stage but the idea is to use magnets to correct for the usual range of optical aberrations that telescopes have to deal with (abstract). And also to allow a liquid telescope to be tilted by using oil that is much more viscous than mercury and correcting any periodic deformation in the fluid that tilting might cause."

Croakyvoice writes "Waninkoko has released the world's first custom firmware for the Nintendo Wii, which is installed using the twilight hack; among its features is the ability to allow writeable DVDs to be read in emulators. From the readme: 'The Custom Firmware installs as IOS249 and it does not modify any other IOS so it is secure to install and has been made to be used ONLY with homebrew software. This is a custom IOS, an IOS modified to add some new features not available in the official IOS.'"

Logged In or Out, Facebook Is Watching You 336

kaos07 links to this ZDNet story, according to which "Researchers at software vendor CA have discovered that social networking site Facebook is able to track the buying habits of its users on affiliated third-party sites even when they are logged out of their account or have opted out of its controversial 'Beacon' tracking service. Responding to privacy concerns, Facebook has since moved to reassure users that it only tracks and publishes data about their purchases if they are both logged in to Facebook and have opted-in to having this information listed on their profile. But in 'extremely disconcerting' findings that directly contradict these assurances, researchers at CA's Security Advisory service have found that data about these transactions are sent to Facebook regardless of a user's actions."

A DIYer's Quick Guide To Cheap Wireless Extension 148

An anonymous reader writes "This piece is described in one of the comments on it as 'a little piece of genius'... and I have to agree! Although Peter Cochrane seems a bit of a crack pot, the ways that he comes up with to get connected when he's out of range in the sticks are pure genius and he makes them appear really simple! Think old satellite dishes, USB dongles and plastic bags and you'd be on the right tracks to upping wi-fi signal by 4 bars." A perfect excuse to link to one of my favorite sites, if you want more details and photos on similar jury-rigged long-distance connections. However, your meterage may vary — I've found USB Wi-Fi devices to be pretty fickle under Linux, with some distros working way better than others.

One small step for man, one giant stumble for mankind.
