Submission + - The Next Solar Cycle May Have Begun (space.com)

Josh Fink writes: "As many of us know, the sun usually works on an 11 year cycle for extreme solar storms and flares. The last time that this cycle peaked was in 2001 and 2002. However, on December 11th, scientists began to observe a "modest knot of magnetism," and are saying this might be the signal for increased activity from our local star. From the article: 'This patch of magnetism could be a sign of the next solar cycle," said solar physicist David Hathaway of the Marshall Space Flight Center. 'Solar minimum is upon us.'....Though forecasts vary wildly, some scientists predict Solar Cycle 24 will be intense. If so, 'it could have significant impacts on telecommunications, air traffic, power grids and GPS systems,' according to the NASA statement."

Submission + - iPhone hacker trades work for fast car, job (networkworld.com)

coondoggie writes: "George Hotz, the teenager from New Jersey who hacked the iPhone last week posted on his blog today that he traded the unlocked iPhone for "a sweet Nissan 350Z and 3 8GB iPhones" and a paid consulting gig. Hotz said he reached a deal with CertiCell, a Louisville, Kentucky-based mobile phone repair company. "We do not have any plans on the table right now to commercialize Mr. Hotz' discovery. However, we are keenly interested in having Mr. Hotz assist our engineers in developing solutions to other software related challenges including software updating, reflashing and memory elimination of repaired and or refurbished cellular handsets," said Terry Daidone, co-founder of Certicell on the firm's Web Site. http://www.networkworld.com/community/node/18815"

Submission + - Modeling Damping for Better Hard Drives (physorg.com)

eldavojohn writes: "Hard drives (at their core) operate on electromagnetic properties and finer control of electrons lead to better drive performance. Which is why PhysOrg's article on recent research is exciting. Researchers have discovered how to model and predict intrinsic dampening[PDF Warning!] of Fe, Co & Ni. They say that these results could be used to optimize damping in new magnetic alloys by using their model to predict intrinsic damping in new alloys without guess & test style development. End result, better micromagnetic control leading to faster read/writes on drives."

Submission + - Scientists prove Schrödinger's cat with l (physorg.com)

0ddity writes: "Australian and French scientists have made another breakthrough in the technology that will drive next generation computers and teleportation. The researchers have successfully superposed light beams, which produces a state that appears to be both on and off at once. Light beams that are simultaneously on and off are vital for the next-generation super computers which should be faster than current computers based on bits, that are either on or off. Previously, only smaller light particles had been superposed and the group has also proved a quantum physics theory known as Schrödinger's cat. http://www.physorg.com/news107177837.html"

Submission + - SPAM: Website Design vs. Consumer Behaviour

rinkjustice writes: "Artist. Psychologist. Wordsmith. Any good webdesigner needs to wear these three hats if they have any chance of converting first-time visitors to loyal customers and readers. "This is Your Brain On My Website" explores the behaviours of the consumer, where their eyes go, and what should meet their eyes to make a positive and lasting impression."

Submission + - The 10 Commandments for New Linux Users (linuxbraindump.org) 2

An anonymous reader writes: Thou shalt not log in as root. Use "sudo" or "su -" for administrative tasks. That's how it starts. The rest are at Linux Brain Dump. How does the Slashdot community feel about these commandments? Should new users adhere to these guidelines? Do you have other suggestions?

Submission + - Black hole seen swallowing star (and belching)

mcgrew (sm62704) writes: "New Sceintest reports that the Swift satellite has detected GRB 070610. From the article:

A black hole has been spotted belching out a burst of gamma rays after gulping down part of a nearby star, something never seen before. Such violent burps may actually be the most common type of explosive "gamma-ray burst" in the universe.

Astronomers led by Mansi Kasliwal of Caltech in Pasadena, US, traced the burst to a star system in our own galaxy, where a black hole and a star slightly less massive than the Sun are orbiting each other.

Observing this black hole outburst from nearby would be a risky prospect. "If you were as close to the black hole as the [companion] star, things wouldn't be pretty," Kasliwal told New Scientist. "I don't think you'd want to be near it."
