+ - Research: Calorie Restriction extends lifespan->

Submitted by Anonymous Coward
An anonymous reader writes "Can humans live up to 150 years by eating a “calorie restricted” (CR) diet? Lab animals of all kinds live up to 50 percent longer on CR diets. And human studies (like CALERIE) seem to indicate that CR extends life in humans too, though it’s too soon to tell by how much. Question is: Would you want to live 150 years? Brian M. Delaney, president of Calorie Restriction Society International, says yes, though the weight loss that goes along with CR is an unfortunate consequence."

+ - Ask Slashdot: Best Certifications To Get?

Submitted by Hardhead_7
Hardhead_7 (987030) writes "Seeing the recent article on Slashdot about how much your degree is worth got me thinking. I've been working in the IT field for several years now, but I don't have anything to my name other than an A+ certificate and vendor specific training (ie, Dell certified). Now I'm looking to move up in the IT field, and I want some stuff on my resume to demonstrate to future employers that I know what I'm doing, enough that I can get in the door for an interview. So my question to Slashdot is this: What certifications are the most valuable and sought-after? What will impress potential employers and be most likely to help land a decent job for someone who doesn't have a degree, but knows how to troubleshoot and can do a bit of programming if needed?"

I think that genius is hard to detect at first sight, you have to know a person of genius level really well and at least to have some grasp of the amazing things they do, but believe me true geniuses are really very distant from average people or even regular smart people, they are simply in other plane. Also, in my experience these factors although important are not sufficient conditions for development of genius, there is always some innate part.
Math

+ - Grad student looking to contribute to Open Source

Submitted by Anonymous Coward
An anonymous reader writes "I am an Applied Math grad student who knows a bit of Mathematics and a bit of programming. C++ being my first programming language, I am decent at it. I wish to start contributing to a numerical library with two purposes — contribute to open source and develop my C++ skills at the same time. I looked at the Boost libraries and joined the developer list. However, I have no idea on how to start contributing. I'm not an expert in template programming, having written only toy programs to understand that concept. I've used some of the OOP constructs like inheritance, but that too only for very small projects.

Could slashdotters please give me tips on how to get started on the contribution? Are there any other emerging numerical libraries to which I can contribute? Are there any other avenues where I can contribute to open source and improve programming skills?"
Technology

+ - Technological Genius is Timeliness Not Inspiration

Hugh Pickens
Hugh Pickens writes "Ezra Klein has an interesting essay in the Washington Post about "simultaneous invention," where technology advances to the point that the next step is obvious to multiple people at once, and so they all push forward with the same or similar inventions because while the natural capabilities of human beings don't change much from year to year, their environments do, and so does the technology and store of knowledge they can access. One good example is Alexander Graham Bell, who in all likelihood invented the telephone after Elisha Gray — and both of them came after Antonio Meucci, who couldn't afford the fee to keep his patent current. "The idea of the lone genius who has the eureka moment where they suddenly get a great idea that changes the world is not just the exception," says Steven Johnson, author of "Where Good Ideas Come From: The Natural History of Innovation," "but almost nonexistent." Or consider Adam Goldberg's CU Community, created in 2003 at Columbia University, a social network that launched first and had cooler features than Facebook, with options for pictures and integrated blogging software. "Today, Zuckerberg is many times as rich as Goldberg," writes Klein. "He won. Zuckerberg's dominance can be attributed partly to the clean interface of his site, partly to the cachet of the Harvard name and partly to luck. But the difference between Mark Zuckerberg and Adam Goldberg was very small, while the difference between what Mark Zuckerberg could do and what the smartest college kid in 1999 could do was huge. It was the commons supporting them both that really mattered. ""

There is a well known rumor that keeping celibacy is a great source of creativity.

From Nikola Tesla's webpage:

"Tesla never married. He was celibate and claimed that his chastity was very helpful to his scientific abilities.[22] Nonetheless there have been numerous accounts of women vying for Tesla's affection, even some madly in love with him. Tesla, though polite, behaved rather ambivalently to these women in the romantic sense."

I am sure i could find some other intellectuals who were celibates, or at least didn't give so much importance to sex. Maybe the greats insights of these genius provided them with greater pleasure (and less ephemeral) as substitute for physical orgasms. Or it may be simply that they didn't have much time or didn't give the importance to it.

Doesn't seem like that requires any real computation - you just go through the data maintaining a count of each of the 256 possible values (an embarassingly parallel problem), then write it back out with 256 memsets (likewise trivially parallelisable).

That technique is called bucked sort BTW.

The most important early product on the way to developing a good product is an imperfect version.
