In spite of the quick-&-dirty DIY nature of the project, the gains in cooling performance are remarkable, especially considering the material cost was only $33. Given the price many enthusiasts will pay for a top-end cooler, it's easy to imagine this product coming to market quite soon."

Submission + - IPv6 flaw could greatly amplify DDoS attacks

tygerstripes writes: The Register has a story about the discovery of a flaw in part of the IPv6 specification which has experts scrambling to have the feature removed, or at least disabled by default. From the article:

The specification, known as the Type 0 Routing Header (RH0), allows computers to tell IPv6 routers to send data by a specific route. Originally envisioned as a way to let mobile users to retain a single IP for their devices... RH0 support allows attackers to amplify denial-of-service attacks on IPv6 infrastructure by a factor of at least 80.
Paul Vixie, president of the Internet Systems Consortium, described the fault bluntly. "It can be exploited by any greedy Estonian teenager with a $300 Linux machine."

Submission + - IBM's to reach 1.6 Petaflops with PS3 Cells

tygerstripes writes: IBM have announced that they are gearing up to build the world's fastest supercomputer — by using a hybrid solution of off-the-shelf CPUs and Cell chips designed for the PS3.

Nicknamed "Roadrunner", it is to be built in a US government laboratory and installed at Los Alamos National Laboratory, occupying approximately 1,100 square metres of floorspace.

According to the BBC:
The computer will contain 16,000 standard processors working alongside 16,000 "cell" processors... each cell is capable of 256 billion calculations per second.
Tha article goes on to mention other, potentially faster, Cell projects (principally SETI@home and folding@home) but points out that these do not require the processes to be in constant communication with one another, unlike the complex complex simulation situations this computer is designed to handle.
