The RIAA's new plan to enlist ISPs in its war on file sharing, once it announced it was calling a halt to new consumer lawsuits, is running into rough sledding. Wired reports on the continuing legal murkiness of the RIAA's interpretation of copyright law. And one small ISP in Louisiana asks the recording organization, "You want me to police your intellectual property? What's your billing address?"

Steve Jobs just got through announcing new MacBook lines in Cupertino. The MacBook, the Pro, and the Air all got revved. The old line of plastic-body MacBooks drops in price by $100, to $999. The new MacBooks have a metal body and multi-touch trackpad, just like the new Pros. The Pro features two NVidia graphics chips. Quoting Jobs: "With the 9400M, you get 5 hours of battery life, with the 9600M GT you get four hours of battery life. You choose." In summary: "We're building both [MacBook and Pro] in a whole new way. From a slab of aluminum to a notebook. New graphics. New trackpad, the best we've ever built. And LED-backlit displays that are far brighter, instant on, far more environmentally responsible." They are shipping today and should be in stores tomorrow. Oh, and one more thing: Steve's blood pressure is 110/70.

Hugh Pickens writes "Although a variety of spore discharge processes have evolved among the fungi, those with the longest ranges are powered by hydrostatic pressure and include 'squirt guns' that are most common in the Ascomycota and Zygomycota. In these fungi, fluid-filled stalks that support single spores or spore-filled sporangia, or cells called asci that contain multiple spores, are pressurized by osmosis. Because spores are discharged at such high speeds, most of the information on launch processes from previous studies has been inferred from mathematical models and is subject to a number of errors, but now Nicholas Money, an expert on fungi at Miami University, has recorded the discharges with high-speed cameras at 250,000 frames-a-second and discovered that fungi fire their spores with accelerations up to 180,000 g, calling it 'the fastest flight in nature.' Money and his students, in a justified fit of ecstasy, have created a video of the first fungus opera."

Croakyvoice writes "Fans of Homebrew on the Nintendo Wii can celebrate with an explosion of releases today, in just a few hours there has been a release of a proof of concept version of Linux for the Wii, an MP3 Player, the Super Nintendo emulator Snes9X has been ported and a converter that converts Gamecube Dol files into Elf for usage on the Wii (Which opens up a multitude of emulators and homebrew games and applications). A tutorial on how to get homebrew working with the Twilight Hack will help those interested."

Hugh Pickens writes "Even low levels of lead can cause brain damage, increasing the likelihood of behavioral and cognitive traits such as impulsivity, aggressiveness, and low IQ that are strongly linked with criminal behavior. The NYTimes has a story on how the phasing out of leaded gasoline starting with the Clean Air Act in 1973 may have led to a 56% drop in violent crime in the US in the 1990s. An economics professor at Amherst College, Jessica Wolpaw Reyes, discovered the connection and wrote a paper comparing the reduction of lead from gasoline between states (PDF) and the reduction of violent crime. She constructed a table linking crime rates in every state to childhood lead exposure in that state 20 or 30 years earlier. If lead poisoning is a factor in the development of criminal behavior, then countries that didn't switch to unleaded fuel until the 1980s, like Britain and Australia, should soon see a dip in crime as the last lead-damaged children outgrow their most violent years."

The Financial Times (via Gamespot) is reporting that (after having already been in stores for about a week), the Xbox 360 Arcade sku is now official. "The $279 Arcade will include a wireless controller and casual games including Pac-Man [Championship Edition], Uno and Luxor 2. Its launch has been widely rumoured but Mr Bach's comments were the first official confirmation. While Microsoft may hope to steal sales from the Wii with the Arcade, its Premium $349 Xbox 360 faces pressure from the $399 PS3, which has a bigger, 40-gigabyte hard drive, built-in wi-fi and a Blu-ray drive."

Cryptocrat writes "Today I blogged about a new method for secure random sequence generation that is based on physical properties of hardware, but requires only hardware found on most computer systems: from standard PCs to RFID tags." Basically he's powercycling memory and looking at the default state of the bits, which surprisingly (to me anyway) is able to both to fingerprint systems, as well as generate a true random number. There also is a PDF Paper on the subject if you're interested in the concept.

paleshadows writes "Researchers at UCSC developed a tool that measures the trustworthiness of each Wikipedia page. Roughly speaking, the algorithm analyzes the entire 7-year user-editing-history and utilizes the longevity of the content to learn which contributors are the most reliable: If your contribution lasts, you gain 'reputation,' whereas if it's edited out, your reputation falls. The trustworthiness of a newly inserted text is a function of the reputation of all its authors, a heuristic that turned out to be successful in identifying poor content. The interested reader can take a look at this demonstration (random page with white/orange background marking trusted/untrusted text, respectively; note "random page" link at the left for more demo pages), this presentation (pdf), and this paper (pdf)."

Roland Piquepaille writes "Yesterday, I told you about virtual beer. Today, we follow two North America researchers who are studying the physics of real beer bubbles. 'Singly scattered waves form the basis of many imaging techniques such as radar or seismic exploration.' But pouring beer in a mug involves multiply scattered acoustic waves. They are more complex to study, but they can be used to look at various phenomena, such as predicting volcanic eruptions or understanding the movement of particles in fluids like beer. They also could be used to monitor the structural health of bridges and buildings or the stability of food products over time. Read more for additional references and a photo showing how the researchers monitor beer bubbles."
