Submission + - BBC Panorama Questions Long-Term Health of Wi-Fi

Submitted by

vtechpilot writes: "From the article:

Britain is in the grip of a Wi-Fi revolution with offices, homes and classrooms going wireless — but there is concern the technology could carry health risks. The Government insists Wi-Fi is safe, but a Panorama investigation shows that radio frequency radiation levels in some schools are up to three times the level found in the main beam of intensity from mobile phone masts.

Submission + - Polyethylene Bulletproof Vests better than Kevlar

Submitted by teflonscout
teflonscout writes: When I think of bulletproof vests, the first word that comes to mind is Kevlar. Wired is running a story on Dynema SB61, a bulletproof material that is made of polyethylene. It is a higher grade of the plastic found in Tupperware. The story also mentions the recall of Second Chance bulletproof vests that were made from Zylon, a material that degraded slowly when exposed to moisture. At least one police officer was injured when a bullet penetrated his Zylon vest. Polyethylene is impervious to moisture. The first vests made from this new material are 5mm thick and can stop at 9mm bullet traveling at 1777 feet per second, which is slightly better than other top of the line vests.

The group, called the "copyright alliance", features the usual suspects: Microsoft, MAFIAA, Viacom und herr Maus ("Look, it's Walt Disney! Shoot him now!"). Funnily enough, there was no mention of information access rights nor of US copyright law's gross violations of basic human rights. Funny that."
It's funny. Laugh.

Submission + - Identical Twins Battle Over Paternety Test

Submitted by ziggamon2.0
ziggamon2.0 writes: Twin brothers Raymon and Richard Miller are the father and uncle to a 3-year-old little girl. The problem is, they don't know which is which. Or who is who. Since they are identical twins, and have the exact same DNA they are inseparable in paternety tests. How is one to know? And if their DNA is really the same, in a biological perspective, does it really matter?

Submission + - Is Modeling Science?

Submitted by

DanielMarkham writes: "I've been watching the flame wars on Global Warming on Slashdot for a few months now. In an effort to ask a simple question without all the flame wars, is modeling science? That is, is creating a computer model the same as coming up with a new law of physics?

I've just got through posting a blog entry in which I make the case that the types of modeling we read about in the news is not science at all, or science as we know it.

This topic has all the nerd stuff you could ever want. Cellular Automata, Turing Tests, Philosophy of Science, nature of chaotic systems, modeling complex software systems in UML. If I've missed something, I'm sure you guys will let me know about it and I appreciate the critique. So what say you? Is modeling science or not? Can we at least agree on this point?"

Submission + - Reduce Global Warming with Biochar

Submitted by Nick Nethercote
Nick Nethercote writes: Want to sequester carbon, create fuel and improve soils in a single step? Then smoulder biomass (such as corn stover or peanut hulls) in the absence of oxygen. The first byproduct is "biochar" (also called "agrichar"), a fertiliser responsible for the rich "terra preta" (black land) soils of the Amazon. The second byproduct is biodiesel, more than enough to fuel the smouldering. And the entire process is carbon negative! The recent International Agrichar Initiative 2007 Conference presented the latest research on this exciting topic. Is this the birth of a new wedge in the fight against global warming?

Submission + - Game designer causes stink with Virginia Tech game

Submitted by Anonymous Coward
An anonymous reader writes: Talk about whistling past the graveyard.

An Australian video game designer has caused a major uproar Down Under with his creation of a game based on the Virginia Tech massacre.

Called V-Tech Rampage, the game has several levels of "stealth and murder," reports The Sydney Morning Herald.

But what really is causing the kerfuffle — as if the game itself wasn't in bad enough taste — is that its designer, Ryan Lambourn, says he will take the game down from his Web site only if the public comes up with a $2,000 payoff.

For another grand, he'll apologize.

"I've done offensive things before, but they're not usually this popular," the Morning Herald quoted Lambourn as saying.

He also said that friends encouraged him to put up the cash payment demand.

"Attention angry people," Lambourn wrote on his site. "I will take this game down from Newgrounds (where the game is hosted) if the donation amount reaches $1,000. I'll take it down from (Lambourn's Web site) if it reaches $2,000 and I will apologize if it reaches $3,000."

It's hard to know how to respond to that. So I won't.

Submission + - Google Nudes Win on Appeal

This attracted attention because of the subject matter — nude photography — and because it represented a significant challenge to the working of the Web. (Perfect 10 also sued Amazon.) Google has now won the case on appeal, according to the Washington Post. It says: The appeals court ruled that the thumbnails fell within a "fair use" exception in copyright law because they play a role in the search process and thus have a function different from that of the original photos. "We conclude that the significantly transformative nature of Google's search engine, particularly in light of its public benefit, outweighs Google's superseding and commercial uses of the thumbnails in this case," Judge Sandra S. Ikuta wrote for the panel. However, "Yesterday's ruling was not a complete victory for Google, because the judges directed the lower court to reconsider a separate finding in the company's favor," says TWP. Basically, it seems the problem is that while Google's thumbnails may not infringe copyright, it was linking to sites that do infringe copyright — and knowing that, not stopping it.

Submission + - Skill based immigration better than H1B?

Submitted by ghoul
ghoul writes: Congress is talking about shifting to skill based immigration instead of family based immigration. This should immediately make it easier for Indian and Chinese Engineers and Scientists to immigrate on green cards without needing to go through the H1B no mans land. This is because under the current system they get stuck as the quota are set to be 7% of total from any country in the world irrespective of population size. This means the Vatican gets the same sized quota as China or India. In the new system the losers are Latin Americans who are mostly unskilled labourers (note mostly I know quite a few Brilliant latin american post grads) but used to be able to get in easier as there being a large number of latin american countires each country got 7%. How does the Slashdot community which has strong opinions on H1B feel about this? As these new workers will be on Green cards they wont be beholden to companies and should not depress the market as they wont take any shit from companies. In fact if the green card process can be shortened down to 6 months H1Bs can be abolished all together. Given this if people still feel this is not right are we still talking about protecting jobs or about fear of the stranger? Canada, Britain and Australia seem to be doing very well with these kind of point based systems.
Programming

Submission + - Do Newer Processors Equate to Slower Applications?

Submitted by MartinJW
MartinJW writes: Bradley Jones presents an interesting point of view on why the advent of multi core processors may reduce the speed of our computers, rather than bring the boost we would initially assume. He touches on the onus developers have to make sure applications are designed to take full advantage of the new architectural paradigm or risk losing favour with their consumers.

From the article:
If you are upgrading to newer processors that have more cores, but slower speeds, then your applications may run slower unless you prepare them to run across multiple processors. While compiler builders such as Codegear (Borland) and Microsoft are sure to build features into their compilers to help with this speed issue, in many ways, the onus is on the developer. It is up to developers to change the design and architecture of their applications to take advantage of the added core. Sequential applications will take advantage of a single core only; if a design change isn't made, you won't gain any speed.

Submission + - When will broadcast TV die?

Submitted by Anonymous Coward
An anonymous reader writes: This article about how to hook up your PC to your living room TV ends up predicting that "I think in the future, the broadcast stations will all turn off. There is a very limited amount of content on them." The billion+ videos on sites like YouTube, Revver or LuluTV dwarf the broadcast and cable stations that are "numbered in the hundreds." Is the snacky nature of Internet video going to rollover the old school broadcast stations? Or will the low cost of broadcasting to millions give the old stations a perpeptual advantage of the new Internet sites that must pay bandwidth to deliver each and every copy?
