Apple Releases Patch For Evasi0n Jailbreak (After It's Used 18 Million Times) 112

Sparrowvsrevolution writes "Apple has released a new update for iOS that prevents the jailbreak evasi0n released last month. But that hacking tool has already become the most popular jailbreak ever: It's been used to remove the software restrictions on 18.2 million devices in the 43 days between its release and the patch, according to data from Cydia, the app store for jailbroken devices. In its announcement of the update, Apple says it has fixed six bugs and was polite enough to credit the hackers behind evasi0n with finding four of them. At least one of the bugs used by evasi0n remains unpatched, according to David Wang, one of evasi0n's creators. And Wang says that he and his fellow hackers still have bugs in reserve for a new jailbreak, although they plan to keep them secret until the next major release."

More Evidence For Steam Games On Linux 256

SheeEttin writes "Back in November 2008, Phoronix reported that Linux libraries appeared in the Left 4 Dead demo, and then in March, Valve announced that Steam and the Source engine were coming to Mac OS X. Now, Phoronix reports that launcher scripts included with the (closed beta) Mac version of Steam include explicit support for launching a Linux version."

New Pi Computation Record Using a Desktop PC 204

hint3 writes "Fabrice Bellard has calculated Pi to about 2.7 trillion decimal digits, besting the previous record by over 120 billion digits. While the improvement may seem small, it is an outstanding achievement because only a single desktop PC, costing less than $3,000, was used — instead of a multi-million dollar supercomputer as in the previous records."

The Noisy and Prolonged Death of Journalism 388

The war of words between the old and the new media is heating up some more. Eric Schmidt has an op-ed in Rupert Murdoch's WSJ (ironic, that) explaining to newspapers how Google wants to, and is trying to, help them. Kara Swisher's BoomTown column translates and deconstructs Schmidt's argument, hilariously. A few days back, the Washington Post's Michael Gerson became the latest journo to bemoan the death of journalism at the hands of the Internet; and investigative blogger Radley Balko quickly called B.S. on Gerson's claim that (all?) bloggers simply steal from (all?) hard-working, honest, ethical print journalists.

The Psychology of Achievement In Playing Games 80

A post on Pixel Poppers looks at the psychological underpinnings of the types of challenges offered by different game genres, and the effect those challenges have on determining which players find the games entertaining. Quoting: "To progress in an action game, the player has to improve, which is by no means guaranteed — but to progress in an RPG, the characters have to improve, which is inevitable. ... It turns out there are two different ways people respond to challenges. Some people see them as opportunities to perform — to demonstrate their talent or intellect. Others see them as opportunities to master — to improve their skill or knowledge. Say you take a person with a performance orientation ('Paul') and a person with a mastery orientation ('Matt'). Give them each an easy puzzle, and they will both do well. Paul will complete it quickly and smile proudly at how well he performed. Matt will complete it quickly and be satisfied that he has mastered the skill involved. Now give them each a difficult puzzle. Paul will jump in gamely, but it will soon become clear he cannot overcome it as impressively as he did the last one. The opportunity to show off has disappeared, and Paul will lose interest and give up. Matt, on the other hand, when stymied, will push harder. His early failure means there's still something to be learned here, and he will persevere until he does so and solves the puzzle."

Submission + - NASA Reproduces a Building Block of Life in Lab (spacefellowship.com)

xp65 writes: NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces this essential ingredient of life. “We have demonstrated for the first time that we can make uracil, a component of RNA, non-biologically in a laboratory under conditions found in space,” said Michel Nuevo, research scientist at NASA’s Ames Research Center, Moffett Field, Calif. “We are showing that these laboratory processes, which simulate occurrences in outer space, can make a fundamental building block used by living organisms on Earth.”

Submission + - Swiss Experimenter Breeds Swarm Intelligence (hplusmagazine.com)

destinyland writes: Researchers simulated evolution with multiple generations of food-seeking robots in a new study of artificial swarm intelligence. "Under some conditions, sophisticated communication evolved," says one researcher. And in a more recent study, the swarms of bots didn't just evolve cooperative strategies — they also evolved the ability to deceive. ("Forget zombies," joked one commenter. "This is the real threat.") "The study of artificial swarm intelligence provides insight into the nature of intelligence in general, and offers an interesting perspective on the nature of Darwinian selection, competition, and cooperation." And there's also some cool video of the bots in action.
