Submission + - Physicists Create Quantum Link Between Photons That Don't Exist at the Same Time (sciencemag.org)

sciencehabit writes: Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or "state," of another particle—even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time. Anton Zeilinger, a physicist at the University of Vienna, says that the experiment demonstrates just how slippery the concepts of quantum mechanics are. "It's really neat because it shows more or less that quantum events are outside our everyday notions of space and time."

Astronauts Could Get Lazier As Mars Mission Progresses 145

sciencehabit writes "Imagine life on a spaceship headed to Mars. You and your five crewmates work, exercise, and eat together every day under the glow of fluorescent lights. As the months pass, the sun gets dimmer and communication with Earth gets slower. What does this do to your body? According to an Earth-based experiment in which six volunteers stayed in a windowless 'spaceship' for nearly a year and a half, the monotony, tight living space, and lack of natural light will probably make you sleep more and work less. Space, for all intents and purposes, turns you into a couch potato."

Actually, almost all of the design decisions in C# (I can't speak for Java) are around pushing the author in the safest and most correct direction (just read Eric Lippert's Blog), and with the advanced refactoring support, it's easier to clean up bad code. In fact, when Roslyn is released, the refactoring capabilities and third party tools will increase by an order of magnitude. I know what language I would prefer my legacy code to be in.

Comment Re:Scratch (scratch.mit.edu) (Score 1) 237

Definitely this! My 13 year old nephew showed it to me yesterday. It allows you to write procedural code but without any typing. Everything is done with drag and drop blocks so you can't cause any kind of syntax errors. This allowed him to see instant results and play about until he got the effect he was after. He showed implicit understanding of concepts like variables, loops, branching etc. He relies a lot on trial and error (which is of course a bad thing) but so did I at that age. The fact is he was getting results and kudos from friends without having to learn OO, memory models, frameworks etc. Whether he will transfer this to real languages remains to be seen.

Comment Re:Endurance Athletes, etc (Score 1) 173

I experience adrenaline when snowboarding and about to attempt, succeed or fail a jump/rail/whatever. More so if it's something I'm less confident on. I also have a mild anxiety disorder. To me these are most definitely NOT the same sensation. I don't understand the biology, but I would say there's a difference when it's a situation you can control, have put yourself in etc.

Comment .Net Contracts are Better! (Score 2) 134

Or you could use the .Net Code Contracts which do all this with static analysis. Therefore you get proof up front that your contracts will never be violated by non exposed code, and without a performance penalty at run time. If a contract cannot be verified, warnings are given. You can then introduce appropriate branching to provide guarantees as necessary. http://research.microsoft.com/en-us/projects/contracts/

Why Money Doesn't Motivate File-Sharers 633

nk497 writes "File-sharers aren't motivated by financial gain, but by altruism, according to an economist. Joe Cox, of the Portsmouth Business School, said those uploading content for others to share don't see what they're doing as illegal, meaning current tactics to deter piracy are doomed to fail. 'The survey data suggested there was a deep-seated belief that this type of activity shouldn't be illegal, that there was no criminal act involved.'"

Ask the UK Pirate Party's Andrew Robinson About the Issues 391

VJ42 writes "With the 2010 UK general election fast approaching, the Pirate Party of the United Kingdom will be fielding elections for the first time. The Digital Economy bill and ACTA are hot topics for UK geeks, and the Pirate Party is looking to pick up some votes. Their leader, Andrew Robinson, has agreed to answer your questions. Normal Slashdot interview rules apply."

MiFi Attack Exploits GPS To Reveal User's Location 62

An anonymous reader writes "Security researcher Adam Baldwin has identified that the Sprint and Verizon MiFi devices are vulnerable to a multitude of attacks. Combining these attacks together, an attacker can gain the GPS location of the MiFi device without the user becoming immediately aware. The attack can be successfully executed without authentication and even if the GPS has been disabled by the administrator." There's a video, but a handy text summary, too. Upshot: "Any MiFi user that visits a specially crafted page will give up their GPS location to the attacker."

Dumbing Down Programming? 578

RunRevKev writes "The unveiling of Revolution 4.0 has sparked a debate on ZDNet about whether programming is being dumbed down. The new version of the software uses an English-syntax that requires 90 per cent less code than traditional languages. A descendant of Apple's Hypercard, Rev 4 is set to '...empower people who would never have attempted programming to create successful applications.' ZDNet reports that 'One might reasonably hope that this product inspires students in the appropriate way and gets them more interested in programming.'"

Tabula Rasa Going Out With A Bang 162

Mytob notes that sci-fi MMO Tabula Rasa is set to close down tomorrow, and the development team has something special planned for the game's final hours. The decision to close the game was made in November, and it went free-to-play a month later, while the developers continued to roll out the new content they had planned. Now, after a round of patches and server merges, the beleaguered MMO has reached its shutdown date. The game's primary enemies, the Bane, are launching an all-out offensive on Allied forces, which will culminate in a battle beginning at 8PM on Saturday and lasting until midnight. All players are being called in as reinforcements in this apocalyptic fight, though the final announcement says, "Penumbra has been informed of the situation and is standing by on the use of their last resort weapon. We can not afford to be complacent or uncertain, but if it is truly our destiny to be destroyed, we are taking them all with us."

UC Berkeley Offering Starcraft Course 148

The Tumeroks blog reports that the University of California, Berkeley is now offering a class on Blizzard's Starcraft real-time strategy game. "This course will go in-depth in the theory of how war is conducted within the confines of the game Starcraft. There will be lecture on various aspects of the game, from the viewpoint of pure theory to the more computational aspects of how exactly battles are conducted. Calculus and Differential Equations are highly recommended for full understanding of the course. Furthermore, the class will take the theoretical into the practical world by analyzing games and replays to reinforce decision-making skills and advanced Starcraft theory."

Comment Re:Smaller better? (Score 1) 139

The smaller the feature size, the faster the chip can be pushed. Alternatively, the chip can run at the same speed with less power. Die shrinks are the reason for the large speed increases all through the nineties. The problem is, the smaller you go the harder they are to make.
