I Don't Believe in Imaginary Property writes "Taser International recently started a legal campaign against medical examiners who claimed tasers contributed to the cause of death for several people. On Friday, an Ohio judge ruled in favor of the stun gun manufacturer (free registration may be required). While they do have a number of scientific studies on which they establish their claims, it's interesting that the alternate cause of death they champion — excited delirium — appears only in police reports on the deaths of difficult or drug-addled inmates, not in medical textbooks. Of course, that may change soon — Taser is funding and promoting research on the subject. Coroner reports such as the ones in this case contributed to the UN's opinion that taser use is torture."

A few days ago, Dan Rutter (the Dan in "Dan's Data") published an interesting idea for extending the sort of philanthropic technical pranksterism that spawned throwies by applying the same approach to Wi-Fi. That means, looking what he hopes is not too far down the road, creating Wi-Fi repeaters that are cheap enough to deploy on the sly and frugal enough with power to run on solar power or cheaply replaceable batteries. But as he says, "If you've got a lot of spare money, a ladder and no respect for private property, though, you could already be stealthily deploying Open-Mesh or other such gadgets all over your neighbourhood." In some cities at least, you'd be hard pressed to ever avoid at least one available wireless access point, but that's not the experience for most people, most places -- which bears correction.

Dionysius, God of Wine and Leaf, writes with a link to a New York Times story on a source of pollution that doesn't leave contrails: "The world's data centers are projected to surpass the airline industry as a greenhouse gas polluter by 2020, according to a new study by McKinsey & Co. ... [C]omputer servers are used at only 6 percent of their capacity on average, while data center facilities as a whole are used at 56 percent of peak performance." Data centers, though, might have more options for going green than airlines do, given present technology.

Starturtle writes "Microsoft chief executive Steve Ballmer had admitted that Microsoft had been working on support for Blu-ray under Windows during this year's Mix08 conference. Rumors began to swirl and many began to expect Microsoft to announce a Blu-ray peripheral for the Xbox 360. However, Microsoft came out and denied all rumors, stating that they were not exploring any kind of Blu-ray add-on or in talks with Sony about integrating Blu-ray into the Xbox experience. After months of rumors and denials, the Xbox 360 with a Blu-ray disc drive is due to be manufactured soon and shipped in Q3 of 2008. Pegatron Technology, an OEM subsidiary of Asustek Computer, is reported to have received the winning order from Microsoft for a Blu-ray equipped Xbox 360."

profdc9 writes "For the past six months or so I have been working on the MiniOn, a network enabled microcontroller programming system, similar in idea to the Basic Stamp and Arduino hobbyists are fond of, but it is programmable and accessible through a Web browser and TELNET, requiring no installed development software. It uses the cheap, readily available LPC2000 ARM7TDMI micrcontrollers, and the easy to interface Microchip ENC28J60 for ethernet. The MiniOn firmware is written using only the free WinARM development tools (Linux tools work also) for those who wish to improve the MiniOn. I have already implemented an MP3 streaming server and a web-based graphical oscilloscope in MiniOnBasic. The MiniOn should hopefully lower the barriers and costs to getting started learning about embedded systems, and provide a non-proprietary method of data acquisition."

babyshiori writes "Now, that must sound pretty inane. After all, overclockers employ all kinds of power-guzzling methods to improve their CPUs' overclockability. However, there are many good reasons to do so. In this guide, we will not just look at theoretical tips on reducing power consumption in overclocked PCs, we will also look at how well they work in real-life situations. Best of all, we are shown why they will improve our PCs' power efficiency without any real loss in performance. Start doing your part in saving the planet now!"

DeviceGuru writes to mention that Honda's ASIMO robot will apparently be leading the Detroit Symphony Orchestra in a performance of "Impossible Dream" from the conductors podium. Along with cellist Yo-Yo Ma, the mechanical marvel will hopefully have a better performance than some of the earlier public appearances. "Honda says it is giving the Detroit Symphony Orchestra a gift of more than $1 million to create The Power of Dreams Music Education Fund. The fund is intended to help the Detroit Public Schools, which has suffered from severe cost constraints that have hurt the district's ability to provide music education, offer students the opportunity to learn to play instruments, read music, and participate in bands or orchestras."

An anonymous reader writes "NVIDIA's CUDA system, originally developed for their graphics cores, is finding migratory uses into other massively parallel computing applications. As a result, it might not be a CPU designer that ultimately winds up solving the massively parallel programming challenges, but rather a video card vendor. From the article: 'The concept of writing individual programs which run on multiple cores is called multi-threading. That basically means that more than one part of the program is running at the same time, but on different cores. While this might seem like a trivial thing, there are all kinds of issues which arise. Suppose you are writing a gaming engine and there must be coordination between the location of the characters in the 3D world, coupled to their movements, coupled to the audio. All of that has to be synchronized. What if the developer gives the character movement tasks its own thread, but it can only be rendered at 400 fps. And the developer gives the 3D world drawer its own thread, but it can only be rendered at 60 fps. There's a lot of waiting by the audio and character threads until everything catches up. That's called synchronization.'"

shankar writes "Engineers at Eyebeam, an art and technology center based in New York, have created a scaled-down open-source version of Surface, called Cubit. By sharing the Cubit's hardware schematics and software source code, the engineers are significantly reducing the cost of owning a multitouch table. 'Multitouch displays are not new technology; in fact, they've been built in research labs for decades. Mitsubishi Electric Research Labs created an iconic multitouch table called DiamondTouch; more recently, Jeff Han, founder of Perceptive Pixel, based in New York, developed wall-sized multitouch screens that he sells to corporations and major government agencies. But because of the falling costs of many touch-screen components, such as infrared light sources and small cameras and projectors, it's now becoming feasible for people without access to a lab or venture-capital money to make their own multitouch displays.'"

haroldag writes "After Walter Bender's resignation as president of OLPC, Charles Kane enters to take his place as the new boss. Kane says 'The OLPC mission is a great endeavor, but the mission is to get the technology in the hands of as many children as possible. Whether that technology is from one operating system or another, one piece of hardware or another, or supplied or supported by one consulting company or another doesn't matter. It's about getting it into kids' hands. Anything that is contrary to that objective, and limits that objective, is against what the program stands for.'"

vossman77 writes "I was looking into renewable energy from a hobbyist perspective, maybe generating a few watts of solar or wind power, just to reduce my electric bill. But upon further review, I found out that I need a special grid-tied AC inverter that shuts off when the grid turns off (for worker safety reasons) and makes the current in-phase with the grid. These two additional features, over the cheap inverters sold at department store, make the cost upwards of $2000, but support more watts than I need. While this is fine for large-scale projects, it is out of range for a small scale hobbyist. A Google search came with some home-brew hacks at best. So, are there any Slashdotters out there doing small-scale renewable energy projects with grid-tied systems? What are other options for the hobbyist to play around with renewable energy, other than charging a cell phone?"

SecureThroughObscure writes tells us about a hack broken by MacOSRumors: you can get free Wi-Fi at Starbucks, Barnes & Noble, and other AT&T hotspots if you know how to set your browser's user agent string (trivial on Safari), and know a valid iPhone phone number. ZDNet blogger Nate McFeters gives some more details and links. This can't last.

Dorkz brings news of a class-action settlement from Creative Labs over the capacity of their HDD MP3 players. Evidently they calculated drive capacity in base-10 (1,000,000,000 bytes per GB) instead of base-2 (1,073,741,824 bytes per GB). The representative plaintiff is entitled to $5,000, and everyone else who bought one of the HDD MP3 players in the past several years gets a 50% discount on a new 1GB player[PDF]. They can also opt for a 20% discount on anything ordered from Creative's online store. Creative has made available all of the necessary legal forms. Seagate lost a similar lawsuit late last year.

BDPrime writes "Michael Manos, Microsoft's director of data center services, shows a 3-D rendering of the company's upcoming containerized data center, which is like a facility full of shipping containers. He also demos Scry, Microsoft's internal data center analytics tool that lets the company monitor the data center's energy use, carbon footprint and power bill. There are a few companies out there that are now touting the data center in a shipping container. Sun was one of the first with its Blackbox, now called the Sun MD, while others include Rackable Systems' ICE Cube and Verari's FOREST."

OshMan writes "University of Pennsylvania's ModLab is doing some interesting stuff with modular robots. In this case involving absolutely no weapons!

Phurge links to an IEEE Spectrum story on an interesting DARPA project with some scary implications about just what it is we don't know about what chips are doing under the surface. It's a difficult problem to find invasive or otherwise malicious capabilities built into a CPU; this project's goal is to see whether vendors can find such hardware-level spyware in chips like those used in military hardware. Phurge excerpts: "Recognizing this enormous vulnerability, the DOD recently launched its most ambitious program yet to verify the integrity of the electronics that will underpin future additions to its arsenal. ... In January, the Trust program started its prequalifying rounds by sending to three contractors four identical versions of a chip that contained unspecified malicious circuitry. The teams have until the end of this month to ferret out as many of the devious insertions as they can."

eldavojohn writes to tell us that Tilera has released a Linux-based development kit for their 64-core system on a chip. "The Tile64 is based on a proprietary VLIW (very long instruction word) architecture, on which a MIPS-like RISC architecture is implemented in microcode. A hypervisor enables each core to run its own instance of Linux, or alternatively the whole chip can run Tilera's 64-way SMP (symmetrical multiprocessing) Linux implementation. An 'iMesh' switching interconnect, developed by Tilera's founder, MIT professor and serial entrepreneur Dr. Anant Agarwal, is said to eliminate the centralized bus intersection that limited scalability in previous multicore designs."

Engadget has had a chance to play around with Psystar's Open Computer and has a few things to say about the controversial machine. "Okay, so we've been playing with the Psystar Open Computer for a few hours now, and we've formed some early impressions and put together a short video of it in action. We haven't really tried to stress the system yet, but based on our other experiences with OSx86 machines, we're expecting things to generally go smoothly. That said, there are some definite rough patches and issues, all mostly having to do with the fact that OS X isn't really built for this hardware."

Lucas123 writes "The same Xerox lab that brought us Ethernet, the GUI and the mouse has demonstrated paper that can be reused after printed text automatically deletes itself from its surface in a day. Instead of trashing or recycling after one use, a single piece of paper can be reused up to 100 times. 'The paper contains specially coded molecules that create a print after being exposed to ultraviolet light emitted from a thin bar in a printer. The ultraviolet bar itself is very small, so it can be used in mobile printers. The technology could also be useful for network printing.'"

esocid writes "Researchers at HP Labs have solved a decades-old mystery by proving the existence of a fourth basic element in integrated circuits that could make it possible to develop computers that turn on and off like an electric light. The memristor — short for memory resistor — could make it possible to develop far more energy-efficient computing systems with memories that retain information even after the power is off, so there's no wait for the system to boot up after turning the computer on. It may even be possible to create systems with some of the pattern-matching abilities of the human brain. Leon Chua, a distinguished faculty member at the University of California at Berkeley, initially theorized about and named the element in an academic paper published 37 years ago. Chua argued that the memristor was the fourth fundamental circuit element, along with the resistor, capacitor and inductor, and that it had properties that could not be duplicated by any combination of the other three elements."
