Submission + - The new market for life-saving kidney-swap chains (miller-mccune.com)

Submitted by
John Mecklin
John Mecklin writes: "Using game theory and market-design software, doctors are arranging kidney-transplant "swaps" — sometimes in long chains — to give more people with renal disease better transplant options and healthier futures. Kidney transplants are the treatment of choice for people with end-stage renal failure, kept alive — barely — with weekly rounds of debilitating dialysis treatments, and nationally, some 78,000 people await transplants. Doctors prefer to use kidneys from live donors because on average they last nearly twice as long as transplants from cadavers, but the need for live kidneys outstrips the supply. To increase the number of live-kidney transplants, doctors are turning to what are known as paired exchanges and even creating chains of exchanges among strangers that link together as many as 10 pairs of live donors and recipients. This push to boost the number of live transplants is improving and even saving lives — but creating logistical and ethical concerns, too."

Submission + - Extrasolar planet was hiding in old Hubble image (sciencenews.org)

Submitted by
Kristina at Science News
Kristina at Science News writes: "A new way to process images reveals an extrasolar planet that had been hiding in an 11-year-old Hubble picture. After ground-based telescopes found three planets orbiting the young star HR 8799, a team took that information and reprocessed some 11-year-old Hubble Space Telescope images. Voila. There was one of the three planets, captured by Hubble but not visible until new knowledge could see the picture in a fresh light. The technique could reveal hidden treasures in many archived telescope images."

Submission + - New Way to Produce Hydrogen (thefutureofthings.com)

Submitted by
Iddo Genuth
Iddo Genuth writes: "Scientists at Pennsylvania State University and Virginia Commonwealth University are producing hydrogen by exposing clusters of aluminum atoms to water. Rather than relying on the electronic properties of the aluminum, this new process depends on the geometric distribution of atoms within the clusters and requires the presence of Lewis acids and Lewis bases in those atoms. Unlike most hydrogen production processes, this method can be used at room temperature and doesn't require the application of heat or electricity to work."

Submission + - RazorSQL as an example of Missed Opportunity (theopensourcery.com)

Submitted by
jbsurveyer
jbsurveyer writes: "RazorSQL is a robust Java app that one can rarely find on LAMP based servers. It is typical of a broad range of Open Java tools (think Alfresco, Maven, Hibernate, etc, etc)that still are not available on most web hosting services and Linux distributions. This is an ongoing shame for the Linux community — why such short sightedness, given that Java's creators (Sun) have been such big contributors to Open Source, is hard to fathom."

Average User Only Runs 2 Apps, So Microsoft Will Charge For More 842

Posted by CmdrTaco from the so-it-can-charge-for-more dept.
Barence writes "Microsoft's decision to limit Windows 7 Starter Edition to running only three concurrent applications could force up the price of netbooks as many manufacturers opt for the more expensive Home Premium. The three-app rule includes applications running in the background but excludes antivirus, and the company claims most users wouldn't be affected by the limit. 'We ran a study which suggested that the average consumer has open just over two applications [at any time]. We would expect the limit of three applications wouldn't affect very many people.' However, Microsoft told journalists at last year's Professional Developers Conference that 70% of Windows users have between eight and 15 windows open at any one time."

Being able to move around your cursor and delete and edit things without leaving your home position can easily *double* your editing speed. That's the reason why people still love vi and Emacs. And this is not a joke.

Well almost. You still have to reach for the ESC key to switch between typing and moving the cursor. I find that slightly harder than reaching for the enter or backspace keys. You can train yourself to reach for it in a certain location, then find that when you switch to a laptop you keep hitting backquote or F1 instead.

Beginning iPhone Development Screenshot-sm 216

Posted by samzenpus from the read-all-about-it dept.
Cory Foy writes "When my wife got a Touch several months back, the first thing I wanted to do was build some applications for it. Who wouldn't want to play with a device that has accelerometers, position sensors and multi-touch gestures? But being new to the Mac world, I needed something to help guide me along. Beginning iPhone Development aims to be that guide. But does it live up to the challenge of teaching a newbie Mac and iPhone developer?" Read below for the rest of Cory's review.

The first algorithm I actually understood and was able to re-implement (in Sinclair Spectrum BASIC) was a bubble sort, so I would recommend that. I had been experimenting with the graphics functions for a couple of months before but I did not learn much from that. I think the important thing is to avoid pointers and also avoid dependence on any OO concepts (it's easy to forget how hard they were to learn.)
It's funny. Laugh.

Meet the New Chess Boxing Champion of the World 235

Posted by timothy from the milda-shibonis dept.
Attila Dimedici writes "A Russian man has just been crowned world champion in the sport of chess boxing. Apparently the idea originated in a French comic strip from the early '90s. In 2003 a Dutch artist decided to bring the 'sport' to life. The 'sport' is played by starting a chess match in the middle of a boxing ring. After four minutes, the chess board is cleared and the opponents box for three minutes. A match consists of six rounds of chess and five rounds of boxing. A match is decided by knockout, checkmate, or points."

Submission + - Virtual Jam Sessions

Submitted by Mickyfin613
Mickyfin613 writes: Ultimate Guitar reports that eJamming, which currently makes software that allows musicians to practice with MIDI enabled musical instruments over the Internet, has announced a service that will work for non MIDI instruments (IE regular guitars, drums, bass). Obviously the service requires high quality audio streaming with extremely low latency, as such, the service isn't recommended for anyone more then a few hundred miles apart from their band mates. Is it a revolutionary musical advancement or just the latest evolution of Guitar Hero/Rock band software? How much can real musicians benefit from practicing over a network, I'm barely qualified to call myself a musician, but to me a good deal of the value of jamming is the interaction with other musicians that might be difficult over the Web. The service will debut at $15 / month for each band member.
