Piston-Powered Nuclear Fusion 147

Posted by Soulskill from the tried-everything-else dept.
katarn writes "General Fusion is a startup proposing they can create commercially viable fusion using acoustic shock waves, triggered by 220 precisely controlled pneumatic pistons. Their approach is based on a US Naval research concept called 'Linus' and old research done by General Atomics. They feel we now have the high-speed, digital processing capable of pulling off this feat, where decades ago the technology was not available. I think we can hold off on the 'vaporware' claims for a bit; everyone is aware of the horrible track record for turning fusion concepts into reality, but they don't claim to be the first with the idea or that there are not substantial challenges in the way. If nothing else, it is a fascinating concept." Los Alamos National Laboratory has further details on this type of fusion, and longtime LANL researcher Ronald Kirkpatrick did an external assessment (PDF) of General Fusion's plans. Popular Science had a lengthy story about the company a while back. The reason they're back in the headlines now is that they've secured enough funding to begin work on a prototype reactor.
Programming

The Best First Language For a Young Programmer 634

Posted by Soulskill from the what-language-do-the-binars-speak dept.
snydeq writes "Fatal Exception's Neil McAllister questions whether Scheme, a dialect of Lisp taught as part of many first-year CS curricula and considered by some to be the 'latin of programming,' is really the best first language for a young programmer. As he sees it, the essentially write-only Scheme requires you to bore down into the source code just to figure out what a Scheme program is trying to do — excellent for teaching programming but 'lousy for a 15-year-old trying to figure out how to make a computer do stuff on his own.' And though the 'hacker ethic' may in fact be harming today's developers, McAllister still suggests we encourage the young to 'develop the innate curiosity and love of programming that lies at the heart of any really brilliant programmer' by simply encouraging them to fool around with whatever produces the most gratifying results. After all, as Jeff Atwood puts it, 'what we do is craftmanship, not engineering,' and inventing effective software solutions takes insight, inspiration, deduction, and often a sprinkling of luck. 'If that means coding in Visual Basic, so be it. Scheme can come later.'"

The Internet Is 'Built Wrong' 452

Posted by CmdrTaco from the because-he-said-so dept.
An anonymous reader writes "API Lead at Twitter, Alex Payne, writes today that the Internet was 'built wrong,' and continues to be accepted as an inferior system, due to a software engineering philosophy called Worse Is Better. 'We now know, for example, that IPv4 won't scale to the projected size of the future Internet. We know too that near-universal deployment of technologies with inadequate security and trust models, like SMTP, can mean millions if not billions lost to electronic crime, defensive measures, and reduced productivity,' says Payne, who calls for a 'content-centric approach to networking.' Payne doesn't mention, however, that his own system, Twitter, was built wrong and is consistently down."

Nissan Adds Robot Helper To Its Concept Car 127

Posted by Zonk from the i-don't-trust-glados-with-a-stick-shift dept.
narramissic writes "Nissan has mounted a robot passenger in the dashboard of its Pivo2 concept car whose job is to keep the driver happy, give spot-on directions, and even check your e-mail. 'We have data that happy drivers' accident rates are drastically lower than depressed ones, so this robot stays there to make sure the driver is happy always,' said Masato Inoue, chief designer at Nissan's exploratory design group, in an interview at the Motor Show. 'This guides the driver and sometimes cheers up the driver. For example, if the driver is irritated it might say 'Hey, you look somehow angry. Why? Please calm down.'' Other features of this vehicle include a cabin that can turn through 360 degrees so you never have to worry about looking behind when you back up and wheels that can twist 90 degrees, eliminating the need to parallel park." The article includes a video of the car talking to the driver, which is kind of adorable in a 'future is now' sorta way.
