If you live in the US, you get a $7500 tax credit off those prices. The cost of recharging depends on where you live. It costs me ~ $1.25 to drive 40 miles EV. Unless electricty is expensive where you live and you don't have solar panels (electricty is pretty expensive in Hawaii for example, but it's a good place to install solar too), then the cost of charging might be an issue. So subtract $7500 from those prices and then subract another $1000 - $2000 per year in fuel costs (depending on how much you drive and what you're comparing it to). Also subtract other maintenance like oil changes, brakes, transmission fluid, tranmission fluid, etc. And the price comes in line. Also on the pro side is that EVs are more plesant to drive. The ICE vehicles you compare them to would seem noisy and slow to me. The point of the OP though is that people who've tried EVs love them. I think part of the issue is that many people don't take the time to weigh all the factors and take into account the savings in fuel and maintenance over the life of the car.

DocBook 5 Screenshot-sm 68

Posted by samzenpus from the read-all-about-it dept.
frisket writes "Definitive guides by the authors or maintainers of software systems tend to have the edge over other documentation because of the insight they provide. DocBook 5 — The Definitive Guide comes well up to scratch. DocBook has long been the de facto standard for computer system documentation in XML (and SGML before that), and Norm Walsh has revised and updated both the language and the documentation in a concise and valuable form, usable both by beginners and by tech doc experts." Read on for the rest of frisket's review.

Ok, I think you miss the point (and there's more research than is summarized in TFA)...when roads feel safe, drivers are more careless and so traffic accidents per passenger mile go up. When roads feel more dangerous, drivers are more careful and traffic accidents per passenger mile go down. This is the same reason all the tech in cars has not saved as many lives as projected...drivers compensate for the added safety of anti-lock brakes by driving more aggressively.

Printable Batteries Should Arrive Next Year 92

Posted by timothy from the return-to-the-goodness-of-aa dept.
FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Something May Have Just Hit Jupiter 299

Posted by kdawson from the jumbo-size-clearasil dept.
The blog of Anthony Wesley, an Australian amateur astronomer, has what may be the first photos of a recent comet or asteroid impact on Jupiter, near the south pole. These photos are 11 hours old. The ones at the bottom of the page show three small dark spots in addition to the main dark mark. The Bad Astronomy blog picked up the story a few hours later — but cautions that what we're seeing may not be an impact event. This is all reminiscent of the closely watched impact of comet Shoemaker-Levy on Jupiter in 1994.

Cats "Exploit" Humans By Purring 503

Posted by kdawson from the frequently-mistaken-for-a-meatloaf dept.
An anonymous reader notes a BBC report on research recently published in the journal Current Biology, indicating that cats manipulate humans by adding a baby-like cry to their purring. "Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a 'soliciting purr' to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a 'cry,' with a similar frequency to a human baby's. The team said cats have 'tapped into' a human bias — producing a sound that humans find very difficult to ignore."

Symantec Exec Warns Against Relying On Free Antivirus 459

Posted by Soulskill from the totally-unbiased-no-really dept.
thefickler writes "Clearly, the rise of free antivirus is starting to worry Symantec, with one of their top executives warning consumers not to rely on free antivirus software (including Microsoft's Security Essentials). 'If you are only relying on free antivirus to offer you protection in this modern age, you are not getting the protection you need to be able to stay clean and have a reasonable chance of avoiding identity theft,' said David Hall, a Product Manager for Symantec. According to Hall, there is a widening gap between people's understanding of what protection they need and the threats they're actually facing."
