Chainsaw-wielding Robotic Submarine 322

Posted by michael from the hockey-mask-optional dept.
merryprankster writes "New Scientist is running a story about Sawfish, a chainsaw-wielding robotic submarine used as an underwater lumberjack. There are some 200 million trees thought to be standing on the floor of hydropower reservoirs worldwide. Sawfish attaches airbags to, and cuts around 9 trees an hour - the trees then float to the surface for collection. Cue the jokes about robotic high heels, suspenders and a bra."

In-Depth Look At LinuxBIOS 284

Posted by timothy from the quickly-quickly dept.
DrSkwid writes "With PhoenixBIOS reading your email because of such inordinate boot up times for Windows and other OSs, it was remarked in #plan9 about our 5s boot times using LinuxBIOS. My friend f2f pasted an article from Linux Journal which looks at the basic structure of LinuxBIOS, the origins of LinuxBIOS and how it evolved to its current state. It also covers the platforms supported and the lessons they have learned about trying to marry a GPL project to some of the lowest-level, most heavily guarded secrets that vendors possess."

Cell Phone-Controlled Game Invades Times Square 40

johnnylooper writes "The bright lights of Times Square tend to draw the eyes of drivers and passers-by, but a new billboard is a whole new kind of distraction. According to NY1 News, high above Times Square, there is now a gigantic video screen featuring a car racing game that anyone with a cellphone can play by dialing an 800 number. Of course, you need to be nearby to see the screen, at 43rd and Broadway. Now if I could just afford an apartment in Times Sqaure..."

'Nano-Lightning' Could Cool Computer Chips 72

Posted by timothy from the applause-would-be-micro-thunderous dept.
FizzyC writes "A story on New Scientist describes a technique to cool computer chips using charged ions. The system consists of 300 electrodes that ionise and then pump the air molecules across the surface of the chip. The Purdue University technology is the first air-based system to produce a cooling rate similar to water - 40 watts per square centimetre."

Sony To Launch E Ink-based eBook In April 424

Posted by timothy from the small-in-japan dept.
Holly Gates writes "Sony will launch an ebook based on E Ink technology in Japan in late April. The screen is about as big as half a paperback book and has a spatial resolution of ~170ppi. The device includes various edictionaries and audio playback functionality. I am a hardware engineer for E Ink by the way, but I figured slashdotters might be interested." An anonymous reader notes that it is supposed to "display over 10,000 pages on a single set of batteries."

Good News From The High-Speed Networking Front 175

Posted by timothy from the two-scoops-of-bits dept.
Degrees writes "Over at Small Times there is an article about two Danish companies that want to make deploying fiber optic lines easier with MEMS-based packaging technology. (MEMS is Micro-Electro-Mechanical Systems - described here). Also mentioned is that the big three U.S. telcos are working on fiber to the home plans." And punkmac points to this eWeek article which begins "An Intel Corp. backed startup, SolarFlare Communications Inc. said Monday that it has developed a working prototype of a chip that will permit 10G-bps communications over standard CAT5e copper wiring. SolarFlare's chip will be used as evidence that 10G-bit over copper can be done, in anticipation of a draft IEEE standard to be developed later this year."

How (and how well) do Wireless "Worldphones" Work? 70

Posted by Cliff from the digging-for-details dept.
Milo_Mindbender asks: "I've seen a number of new phones (like the Sony T616) advertised as 'worldphones' that handle three or four GSM bands. As someone who travels to Japan and Europe occasionally I'm wondering how (and how well) these actually work. Can you get a temporary or prepaid SIM with a local carrier and just swap it or are the US carriers 'service locking' phones so you have to do international roaming with them even in foreign countries?"

Real Time Video Stream over Firewire? 63

Posted by Cliff from the high-quality-webcams dept.
videomotion asks: "Digital camcorders from Sony and others are very handy gadgets. It is easy to capture or download on to the PC what you have previously recorded on the camcorder's digital tape. It would be wonderful if the same Firewire interface could be used to stream real time video to your PC for cool machine vision applications or for direct capturing of video onto the hard drive. Is it possible get the real time video stream from the Sony digital camcorder (DCR-PC100) through the Firewire cable and display the video picture on your computer screen?"

Backward Compatibility in Next-Gen Consoles? 108

Posted by simoniker from the speculate-away dept.
jvm writes "A new article at Curmudgeon Gamer speculates on the prospects for backward compatibility in the upcoming generation of video game consoles. Sony's PlayStation 3 will reportedly play both PSOne and PlayStation 2 games, but how it will achieve this is unknown. Building from the facts we know and the rumored specifications, can we look forward to replaying Legend of Zelda: The Wind Waker on the GameCube 2 and Halo on the Xbox 2?"

Swap File Optimizations? 177

Posted by Cliff from the coaxing-out-more-speed-via-organization dept.
fastswap asks: "I've got a pretty standard computer with reasonably fast drives. I've got an old 2GB-but-fast drive, and a spare channel on the motherboard. Does it make sense to install the 2GB drive on its own controller and use it for a dedicated, fixed swap file? I figure if the computer's using the swap file, then in the current setup with the swap file on the primary controller, then it's contributing to hard drive thrash exactly when one doesn't want it to (i.e. when the machine needs the swap file). If it is better to have a dedicated swap file on its own controller, is the same true for other operating systems with similar approaches to virtual memory? Since drive space is so cheap now, should the swap file be fixed size anyway rather than letting Windows suddenly get the urge to resize the thing?"

The Arrival of Very Small Memory 175

Posted by Hemos from the mixing-our-terms dept.
Roland Piquepaille writes "After the ages of DRAM and SRAM memories, is this time for nanotech memories? ExtremeTech says that "molecular memories" as well as memories based on carbon nanotubes are emerging. With these nanotech memories, several startup companies are envisioning future chips mixing logic, memory and reconfigurable computing elements. One of these promising startups is ZettaCore, which has built a prototype of a molecular memory designed to replace both SRAM and DRAM kinds of memories. These molecules, which are about 1 nanometer in size, are also self-assembling, meaning that they can be manufactured with existing equipment used in the semiconductor industry. This overview contains more details about the technology and includes a diagram of these molecules in a memory array."

Game Wars 2 - Battle for the Living Room 244

Posted by simoniker from the carbonitization-in-process dept.
securitas writes "The New York Times' John Markoff writes about the fight to own the living room in the next-generation game console wars, with a digital divergence predicted instead of the much-hyped convergence. With games historically being a driving force in consumer PC growth, Intel is pushing PC-based systems as the dominant platform while the videogames industry is looking to the next generation of consoles as media hubs. Sony, Nintendo and IBM are firmly in the console camp. Microsoft has one foot in each of the PC and console camps, cooperating with Intel on the PC front while looking to IBM for the next Xbox. Meanwhile, Apple is taking its own tack, buoyed by the phenomenally successful iPod. Steve Jobs has been highly critical of iPod clones with video and gaming features, and some are looking to Apple for the next home entertainment revolution. Markoff also talks to WildTangent's founder Alex St. John, who predicts the PC makers and Intel have a losing strategy."

AMD Papers Over Free Wi-Fi Network Builders 221

Posted by timothy from the still-sounds-like-a-great-idea dept.
Glenn Fleishman writes "It's been widely reported in the last week that AMD, Intel's processor competitor, was launching a free hotspot network. It's come out, in reporting we just posted at Wi-Fi Networking News, that AMD has built this network by calling existing free hotspots and asking if they'd put stickers in their window. This might be fine: stickers and the label "AMD HotSpot" in exchange for promotion. However, in Austin several local wireless activists say that AMD has put their hotspot decals up in stores without the stores' permission, including at locations operated and supported by Austin Wireless City and Austin Unleashed. Guerrilla marketing gone overzealous? Or an attempt to seize the credit without paying for it?"

Getting A Laptop With The Low U.S. Dollar 1039

Posted by timothy from the used-to-be-volvos-in-sweden-this-way dept.
An anonymous reader submits "I am heading to the U.S. pretty soon and am keen to take advantage of the low US$ to buy a laptop. The differences in prices are astounding - on dell.com (US) you pay $2049 for a Precision M60 - in the UK this costs 1620.33UKP, or $2999. That is a fair difference! It makes it cheaper for me to fly to the US to buy it and carry it home than it is for me to buy it in the UK. Now, that said, it isn't particularly easy to find a place to buy a laptop from, since most of the places don't ship to the UK (or it takes weeks) and it is difficult to get stuff delivered to your hotel ... any suggestions of how I can get a good laptop in the New York area when I am only there for 4 days?"
