She even lists out the names of offenders and shows you the cease-and-desist letter she sends them. And, especially don't copy any of the text on her website, because she's using a bit of javascript that will warn you 'Copyright Protect!' if you right click on a link."

thecarchik writes "It is not an easy task to compare the environmental effects of battery powered cars to those caused by conventionally fueled automobiles. The degree to which manufacture, usage and disposal of the batteries used to store the necessary electrical energy are detrimental to the environment is not exactly known. Now, for the first time, a team of Empa scientists have made a detailed life cycle assessment (LCA) or ecobalance of lithium-ion (Li-ion) batteries, in particular the chemically improved (i.e. more environmentally friendly) version of the ones most frequently used in electric vehicles. Researchers decided to find out for sure. They calculated the ecological footprints of electric cars fitted with Li-ion batteries, taking into account all possible relevant factors, from those associated with the production of individual parts all the way through to the scrapping of the vehicle and the disposal of the remains, including the operation of the vehicle during its lifetime."

trianglecat writes "The not-for-profit agency Canadian Blood Services has a section of their website based on the Japanese cultural belief of ketsueki-gata, which claims that a person's blood group determines or predicts their personality type. Disappointing for a self-proclaimed 'science-based' organization. The Ottawa Skeptics, based in the nation's capital, appear to be taking some action."

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

An anonymous reader writes "I work at a small but growing startup company. Currently, our directory and authentication information is scattered across many systems and wikis, and is becoming increasingly difficult to manage. We are looking at centralizing this information in a directory service to minimize administrative overhead as we continue to grow. The service must support basic directory searches, as well as user authentication for Linux and Windows hosts. Although we are primarily a Linux shop, there are a handful of Windows systems that will be on a Windows Active Directory domain. Most directory servers seem to support integration with other directory servers, however it seems like it may be easiest to just use Active Directory for everything. Are there any pitfalls with this approach? If you had the chance to redesign your enterprise directory service without regard for legacy services, how would you do it?"

Joe Decker writes "The Nevada Lightning Laboratory has experimented with Nicola Tesla's methods of wireless power transmission to push 800 Watts over 5 meters, besting MITs mark of 60W over 2 meters last year. (May I dream of wireless laptop power? I hate power cords.)"

An anonymous reader writes "Working for the Olympics as an IT contractor, I recently moved to the Media Village (where all of the reporters live) and was surprised the there was no free internet. BOCOG (Beijing Organizing Committee of the 2008 Olympic Games) is charging a ridiculous amount of money for ADSL service: for 512/512 it costs 7712.5 RMB (1131.20 USD); for 1M/512 it costs 9156.25 (1342.95 USD); for 2M/512 it costs a whopping 11,700 RMB (1716.05 USD). That is for only one month! For extra features like a fixed IP? That costs an additional 450 RMB (66 USD). I just can't believe that not only do I have to deal with the Great Firewall of China, but also pay through the nose to use it!"

AmericanInKiev writes "Computer World posted a piece on Al Gore and his claim that solar cells will improve at the same rate as microprocessors. Vinod Khosla on the other hand has expressed disappointment that the doubling rate for price/performance of PV is 10 years rather than 18 months for transistors. Which of these two has the facts on their side?" Before anyone has him inventing the Internet again, note that Gore's claim as related in the article is much milder than that Moore's Law applies to solar cells per se -- namely, he's quoted as saying "We're now beginning to see the same kind of sharp cost reductions as the demand grows for solar cells." An optimistic statement, but not a flat-out silly one.

Now.Imperfect writes "In its last day of session, the Supreme Court has definitively clarified the meaning of the Second Amendment. The confusion is whether the Second Amendment allows merely for the existence of a state militia, or the private ownership of guns. This ruling is in response to a case regarding the 32-year-old Washington DC ban on guns." This is one of the most-watched Supreme Court cases in a long time, and Wikipedia's page on the case gives a good overview; the actual text of the decision (PDF) runs to 157 pages, but the holding is summarized in the first three. There are certainly other aspects of the Second Amendment left unaddressed, however, so you can't go straight to the store for a recently made automatic rifle.

I Don't Believe in Imaginary Property writes "The US Patent & Trademark Office has invalidated all 44 claims in Blackboard's patent. While this is a non-final action [PDF], which means that Blackboard will be able to appeal, it does represent a win for the Software Freedom Law Center which had requested the reexamination of Blackboard's patent. It is not yet known how this will affect the $3.1M judgment Blackboard won from Desire2Learn."

Edis Krad writes "While RealID in the US is a threat whose implementation is a ways in the future, the Japanese long ago implemented something similar; and there has been very little complaint raised about it. The Juki Net (Residents Registration Network — link in Japanese) has been silently developing since 1992. The system involves an 11-digit unique number to identify every citizen in Japan, and the data stored against that ID covers name, address, date of birth, and gender. Many Japanese citizens seem to be oblivious that such a government-run network exists. Juki Net had a spotlight shone on it recently because a number of citizens around the country sued against it, citing concerns of information misuse or leakage. And while an Osaka court ruled against the system, the Japanese Supreme Court has just ruled it is not unconstitutional, on the grounds that the data will be used in a bona-fide manner and there's no risk of leakage. While there is a longstanding registration system for us foreigners in Japan, what astonishes me is how the government can secretly implement such a system for its citizens, and how little concern the media and Japanese citizens in general display about the privacy implications."

An anonymous reader sends us to CNET UK's Crave blog, where they report on a demo from CES. So far the only uses for Cell chips have been research stuff and the PS3. Now Toshiba has put a Cell chip into a consumer laptop; they are calling it the Spurs Engine. "The system was demonstrated in modified Qosmio G45 laptops, each of which uses a standard Intel Core 2 Duo CPU in addition to a Cell chip with four 1.5GHz synergistic processing elements (SPEs). Toshiba had four demos running... Demo 3... scans all your movie files, recognizes faces, and creates thumbnails of those faces. You can then click the thumbnails to watch scenes with those faces in, or compile them in a separate playlist."
