Using a House's Concrete Foundation To Cool a PC 465

Agg writes "Well the slab gets poured on Wednesday so I thought I would sink 6 meters of copper pipe in the slab so that I can run my water loop through it when the house is finished. I hope to have water year round at about 16deg [about 61F]. No need for radiators or fans with chilled water coming straight out of the slab!"

Sunspots May Be Different During This Solar Minimum 95

from the too-much-clearasil dept.
PhreakOfTime writes "According to Bill Livingston and Matt Penn of the National Solar Observatory in Tucson, Arizona, sunspot magnetic fields are waning. The two respected solar astronomers have been measuring solar magnetism since 1992. Their technique is based on Zeeman splitting of infrared spectral lines in radiation emitted by iron atoms in the vicinity of sunspots. Extrapolating their data (PDF) into the future suggests that sunspots could completely disappear within decades." To motivate their interest the researchers mention the Maunder Minimum, which occurred beginning in 1645 and coincided with the coldest part of the so-called "Little Ice Age." Sunspot counts during this period were as low as 1/1,000 of the numbers seen in modern times.

WebKit For Metacity/Mutter CSS Theming? 124

Posted by kdawson
from the future-proofing dept.
An anonymous reader writes "As Metacity (the GNOME window manager) evolves into Mutter, the question of CSS themes and how to implement them has come up. One of the proposals was WebKit, which the author asked more specifically about on his blog. It seems that WebKit, being a very fast rendering engine, would allow Mutter to have unprecedented power, not to mention being nearly future-proofed. As a major bonus, going this way could allow GNOME to share themes with KDE, which is apparently already headed towards a dependency on WebKit. Many people will reflexively recoil at the idea of a browser being mixed with a window manager. But it's important to remember that WebKit is not a browser — it's just a rendering engine, and it's not where all the security issues come from. So, what are the real technical issues at stake here? What are the pros and cons of using WebKit underneath GNOME rendering?"

+ - SPAM: Real Nanotechnology Getting Closer, says Drexler 1

destinyland writes "Sun Microsystems has helped fund a 198-page nanotechnology roadmap — but how close are we to real nanotechnology? A science writer asked four nano pioneers, including K. Eric Dexler ("progress is accelerating") and Ralph Merkle ("the exponential trends continue to be exponential") Though we don't have Star Trek replicators yet, the article lists some surprising recent nano developments (artificial tissue, nanoparticle sheets, ultrathin diamond nanorods). And the roadmap's scientists are envisioning targeteted cancer therapies, super-efficient solar cells, high-density computer memory chips and even responsive "smart" materials.""

+ - 4Chan Attacks YouTube, Uploads Kids Clips w/ Porn-> 2

Submitted by Anonymous Coward
An anonymous reader writes "Anonymous members of the internet board 4Chan have organized an attack on YouTube, uploading a number of children's clips and cartoons that switch mid-movie to videos depicting adults engaged in various sexual acts. This is very reminiscent of their attack last year on an internet forum for epileptics, which triggered a number of photosensitive seizures by uploading fast-moving and colorful images to the forum."
