WTF is this? There are about 50 Mersenne primes known, so even ignoring that most of them are impractically large, picking any 3 as the secret key only allows for a keyspace of about 17 bits. And why is a crypto paper "published" in the International Journal of Chemical Sciences, anyway?

Submission + - Bruce Perens: Potential Contributory Infringement Risk for Grsecurity Customers (perens.com)

NewGnu writes: Grsecurity is a patch for the Linux kernel which, it is claimed, improves its security. It is a derivative work of the Linux kernel which touches the kernel internals in many different places. It is inseparable from Linux and can not work without it. it would fail a fair-use test (obviously, ask offline if you don’t understand). Because of its strongly derivative nature of the kernel, it must be under the GPL version 2 license, or a license compatible with the GPL and with terms no more restrictive than the GPL. Earlier versions were distributed under GPL version 2.

Currently, Grsecurity is a commercial product and is distributed only to paying customers. My understanding from several reliable sources is that customers are verbally or otherwise warned that if they redistribute the Grsecurity patch, as would be their right under the GPL, that they will be assessed a penalty: they will no longer be allowed to be customers, and will not be granted access to any further versions of Grsecurity. GPL version 2 section 6 explicitly prohibits the addition of terms such as this redistribution prohibition.

By operating under their policy of terminating customer relations upon distribution of their GPL-licensed software, Open Source Security Inc., the owner of Grsecurity, creates an expectation that the customer’s business will be damaged by losing access to support and later versions of the product, if that customer exercises their re-distribution right under the GPL license. This is tantamount to the addition of a term to the GPL prohibiting distribution or creating a penalty for distribution. GPL section 6 specifically prohibits any addition of terms. Thus, the GPL license, which allows Grsecurity to create its derivative work of the Linux kernel, terminates, and the copyright of the Linux Kernel is infringed. The contract from the Linux kernel developers to both Grsecurity and the customer which is inherent in the GPL is breached.

Indeed. Here's the relevant research paper: http://www.hml.queensu.ca/files/TeleHuman%20CRC.pdf . Nothing to do with holography, just a cylindrical screen projecting an image from a standard stereoscopic projector.

Hamid Shahriari, the secretary of Iran's National Council of Information did not explain why the sites were being blocked. Google, Gmail and several other foreign sites appeared to be inaccessible to Iranian users from Monday morning. Iran has tough censorship on cultural products and internet access, banning thousands of websites and blogs containing sexual and politically critical material as well as women's rights and social networking sites."
