Potato-Powered Batteries Debut 284

MojoKid writes "Yissum Research Development Company Ltd., the technology transfer arm of the Hebrew University of Jerusalem, has just introduced what it's calling 'solid organic electric battery based upon treated potatoes.' In short, it's a potato-powered battery, and it's as real as you're hoping it is. The simple, sustainable, robust device can potentially provide an immediate inexpensive solution to electricity needs in parts of the world lacking electrical infrastructure. Researchers at the Hebrew University discovered that the enhanced salt bridge capability of treated potato tubers can generate electricity through means readily available in developing nations."

Home Computers Equal Lower Test Scores 278

An anonymous reader writes "Politicians and education activists have long sought to eliminate the 'digital divide' by guaranteeing universal access to home computers, and in some cases to high-speed Internet service. But a Duke University study finds these efforts would actually widen the achievement gap in math and reading scores. Students in grades five through eight, particularly those from disadvantaged families, tend to post lower scores once these technologies arrive in their homes."

Several readers made sure we are aware that Slackware 13.1 release is out. Here's the list of mirrors. "Slackware 13.1 brings many updates and enhancements, among which you'll find two of the most advanced desktop environments available today: Xfce 4.6.1, a fast and lightweight but visually appealing and easy-to-use desktop environment, and KDE 4.4.3, a recent stable release of the new 4.4.x series of the award-winning KDE desktop environment."

76% of Web Users Affected By Browser History Stealing 130

An anonymous reader writes "Web browser history detection with the CSS:visited trick has been known for the last ten years, but recently published research suggests that the problem is bigger than previously thought. A study of 243,068 users found that 76% of them were vulnerable to history detection by malicious websites. Newer browsers such as Safari and Chrome were even more affected, with 82% and 94% of users vulnerable. An average of 63 visited locations were detected per user, and for the top 10% of users the tests found over 150 visited sites. The website has a summary of the findings; the full paper (PDF) is available as well."

I really wish someone got around to solve the binary problem once and for all, so Usenet again could be for discussions. By all means, it needs upgrades, like native Unicode support

Usenet is encoding-agnostic: Unicode support depends solely on your client.

and better anonymisation

Pick a server that encrypts your IP. Even some of the free ones will do this (e.g.: news.albasani.net, news.aioe.org).

The Status of Routing Reform — How Fragile is the Internet? 139

crimeandpunishment points out the Associated Press's look (as carried by SkunkPost) "at an issue the government has been aware of for more than 20 years, but still isn't fixed and continues to cause Internet outages: a flaw in the routing system that sends data from carrier to carrier. Most outages are innocent and fixed quickly, but there's growing concern the next one could be devastating. A general manager at Renesys Corporation, which tracks the performance of Internet data routes, says, 'It amazes me every day when I get into work and find it's working.'"

Your only criteria for web browsers is that they run flash well????

The built in browser in the iPad is *horrible* for casual browser. It's basically unusable for me. I do like the iPad for some things, but those are very specific & constrained uses, and web browsing is certainly not one of them.

If you define enough real world processes as calculation, you prove none of our laws of physics are the real ones.

      For just one example, Nature can't be storing irrational numbers as infinite series expressions (where would the infinitely large registers to store them be?). Another way to put this is, if some process in Nature counts as a calculation, Nature can't be doing that calculation using numbers such as pi or e, but rather finite approximations of such numbers, that allow results in finite time.

There exists a small number of physicists who are willing to entertain the idea that Nature does not, in fact, deal with any irrational numbers. If all measurable values are quantized (including time and space), then Nature need not bother with "real" numbers. Nature might be perfectly content to get by with, say, some large algebraic extension of the rationals.

The problem today is, we aren't dealing with a government. We are dealing with idealogues, zealots, and radicals.

Now, take another look at Germany and Japan, and the rest of the Axis powers. Have the allies succeeded in stamping out the ideas of Nazism, and the divinity of the Emperor? Today, there are more skinheads, neonazis, and white supremacists here at home and around the world, than there were in 1940. Japan's Emperor is still a divine figure, if diminished in power.

No government has the power to root out an ideology, and crush it. And, I hope that no government ever does get that power.

Al Gore's "Earth in the Balance" advocates reduction of the earth's population by more than 2/3, before the end of the century. Methodology for accomplishing this is not elaborated on; yet the only way to reduce population that drastically in that short a time frame is either mass sterilization, or mass genocide.

Please quote a relevant excerpt of the book advocating genocide, not fanciful conspiracy theories.

How do you suppose THAT would effect global climate, eh?

*Global* climate ? Probably not a lot. Do you have any evidence to support your idea ? Can you propose a more effective way of reducing emissions ?

Comment Re:Blow to 'creation science' (Score 1) 435

So basically you're proposing a model in which there is selection and crossover but no mutation.

In this case, the total diversity in any population (including "the total of all animals on earth") can only go down. Right?

So then why do there appear to be species around now that were not around, say, during the time of the dinosaurs (because they do not seem to appear in the fossil record). How can new things be created after the Creation, without mutation? Or is the Genesis account of Creation to be understood in a metaphorical sense, and is it still ongoing? If so, is mutation a reasonable way to explain the mechanism by which this occurs? Or is this straying too far from a literal interpretation of scripture (and do we need a literal interpretation?)?

It has only been in the past 6 months that I've thought about replacing it. It just can't handle the load of spam I get, plus spamassassin and a couple other anti-spam counter-measures. Each message takes about 5 seconds to process on this old iron

Try to replace SpamAssassin (written in Perl) with Bogofilter (written in C). You'll have to retrain the filter, but improvements in memory usage and speed are assured.
