"Good Enough" Computers Are the Future 515

An anonymous reader writes "Over on the PC World blog, Keir Thomas engages in some speculative thinking. Pretending to be writing from the year 2025, he describes a world of 'Good Enough computing,' wherein ultra-cheap PCs and notebooks (created to help end-users weather the 'Great Recession' of the early 21st century) are coupled to open source operating systems. This is possible because even the cheapest chips have all the power most people need nowadays. In what is effectively the present situation with netbooks writ large, he sees a future where Microsoft is priced out of the entire desktop operating system market and can't compete. It's a fun read that raises some interesting points."

Intel Cache Poisoning Is Dangerously Easy On Linux 393

Julie188 writes "A researcher recently released proof-of-concept code for an exploit that allows a hacker to overrun an Intel CPU cache and plant a rootkit. A second, independent researcher has examined the exploit and noted that it is so simple and so stealthy that it is likely out in the wild now, unbeknownst to its victims. The attack works best on a Linux system with an Intel DQ35 motherboard with 2GB of memory. It turns out that Linux allows the root user to access MTR registers incredibly easily. With Windows this exploit can be used, but requires much more work and skill and so while the Linux exploit code is readily available now, no Windows exploit code has, so far, been released or seen. This attack is hardware specific, but unfortunately, it is specific to Intel's popular DQ35 motherboards."

CSIRO Settles With Tech Giants Over WiFi Patent Spat 92

Combat Wombat brings news that the legal battle between the Australian Commonwealth Scientific and Research Organisation (CSIRO) and a host of major tech corporations has come to end, with a large settlement going to the CSIRO. The fight was over a patent on wireless LAN technology, which already earned the CSIRO a victory in court over Buffalo Technology and a settlement with Hewlett-Packard. The remaining 13 companies, which include Dell, Intel, Microsoft and Nintendo, have now chosen to settle as well. "[The CSIRO] will use the money won from a Wi-Fi technology patent battle to fund further research. ... It is unclear how much money has flowed to the CSIRO, but experts say the technology would be worth billions of dollars if royalties were paid on an ongoing basis."

Developing Battery Replacement Infrastructure For Electric Cars 369

FathomIT sends in a NY Times profile of Shai Agassi, owner of a company named Better Place, who is working to build the infrastructure to support large numbers of small-scale charging spots for electric cars, as well as fast, automated battery swap stations. "The robot — a squat platform that moves on four dinner-plate-size white wheels — scuttled back and forth along a 20-foot-long set of metal rails. At one end of the rails, a huge blue battery, the size of a large suitcase, sat suspended in a frame. As we watched, the robot zipped up to the battery, made a nearly inaudible click, and pulled the battery downward. It ferried the battery over to the other end of the rails, dropped it off, picked up a new battery, hissed back over to the frame and, in one deft movement, snapped the new battery in the place of the old one. The total time: 45 seconds."

Sink Your Balls Quickly With Pool-Cue Robots 79

AndreV writes "In another attempt to dehumanize our bar games, a Canadian engineer has turned the classic game of billiards on its head with his BilliardBots pet project, which consists of a series of remote-controlled mobile robots meant to replace the standard cue sticks normally used to pocket pool balls. While in his version the basic rules remain, unlike regular billiards, players in this version simultaneously rush to pocket their designated balls (they don't take turns), 'thus it's very competitive and fast,' the creator says. In order to keep tight reins on the mechatronic ball handlers' movements, he adapted a pair of Playstation controllers and says that playing 'requires dexterity, like a video game,' to control their 3.5-m/sec-maximum speeds. The 'bots are designed simply but effectively, using a 3-by-3-by-3-inch metal frame with an electronic board, two motors and rechargeable battery packs. Using a Bluetooth wireless communication protocol, its commands come from the wireless controller with single or double joystick selectable control (the other buttons are not used). Its other parameters are software programmable, such as maximum acceleration rate, maximum speed and maximum rotation speed."

First Android-Based Netbook, Set-Top Box 114

An anonymous reader writes "China based Skytone famous for making skype headsets have brought out a $100 device, the Alpha-680 netbook running Google Android for its OS. The device has Wi-Fi, Ethernet, USB ports and an SD card slot. After watching the video though, I get a feeling that the boot time is somewhat long. IMO good enough for browsing." Also on the Android front, ruphus13 points out what the maker claims is the first "fully realized" non-mobile Android device (though I think there were some other non-mobile gadgets on diplay at CES), a set-top box from Motorola based on Android. According to the linked post, it's "capable of playing DVDs and CDs, transferring music and video to a mobile device, and ripping and storing files" and "will have a full-featured Chrome-like browser."

Bohemian Rhapsody On Old Hardware 137

eldavojohn writes "The sweet sweet melodies of Queen and the late Freddie Mercury are reproduced by hardware almost as old as the song is. 'There are millions of computers sitting idle at home consuming fantom electricity. Let's see where all that power is going. This is dedicated to all fans of Queen and hey let's not forget about Mike Myers and Dana Carvey of Wayne's World. Please note no effects or sampling was used. What you see is what you hear (does that even make sense?) Atari 800XL was used for the lead piano/organ sound, Texas Instruments TI-99/4a as lead guitar, 8 Inch Floppy Disk as Bass, 3.5 inch Hard drive as the gong, HP ScanJet 3C was used for all vocals. Please note I had to record the HP scanner 4 separate times for each voice. I tried to buy 4 HP scanners but for some reason sellers on E-Bay expect you to pay $80-$100, I got mine for $30.'"

Vatican To Build 100 Megawatt Solar Power Plant 447

Karim Y. writes "The Vatican is going solar in a big way. The tiny state recently announced that it intends to spend 660 million dollars to create what will effectively be Europe's largest solar power plant. This massive 100 megawatt photovoltaic installation will provide enough energy to make the Vatican the first solar powered nation state in the world! 'The 100 megawatts unleashed by the station will supply about 40,000 households. That will far outstrip demand by Pope Benedict XVI and the 900 inhabitants of the 0.2 square-mile country nestled across Rome's Tiber River. The plant will cover nine times the needs of Vatican Radio, whose transmission tower is strong enough to reach 35 countries including Asia.'"

Energy-Beaming Space Collector To Also Alter Weather? 274

Recently we covered California utility company PG&E's ambitious deal with upstart Solaren to beam energy to earth from a space-based solar collector. What we didn't know is Solaren's patent also covers the alteration of weather elements with that very same system. "By heating up the upper and middle levels of an infant hurricane, they say they could disrupt the flows of air that power the enormous storms. Air warmed by tropical waters flows up through a hurricane and is vented through the eye into the upper atmosphere. Theoretically, you could heat up the top of the storm and lower the pressure differential between layers, resulting in a weaker storm. "

Skin-Based Display Screens From Nanotech Tattoos 200

destinyland writes "Rensselaer Polytechnic Institute in New York is developing flexible nanotubes inserted under the skin to create a handheld display — inside your hand. They wirelessly receive data and display reminders and text messages, and the concept has also been broadened to suggest endlessly programmable digital tattoos, while Netherlands-based Royal Philips Electronics is also exploring the concept of the body as 'a platform for electronics and interactive skin technologies'." That middle link is quite old, but is still loaded with interesting links.

Hands-on With the Wii MotionPlus 153

Parz writes "In June, Nintendo will be releasing a peripheral called MotionPlus. This small device attaches to the bottom of the Wii-mote and acts as a more sophisticated motion-sensor to the controller as it currently stands. Its goal is to bring greater parity between a user's movements and the animations that they bring to life on-screen. Gameplayer got some hands-on time with the device, and they are extremely impressed." The MotionPlus will only affect new games; Nintendo has said they have no plans to add support for older titles. Virtua Tennis 2009 will be the first game to support it, and Eurogamer has a look at the game both with and without the MotionPlus.

Next-Gen Nuclear Power Plant Breaks Ground In China 426

An anonymous reader writes "The construction of first next-generation Westinghouse nuclear power reactor breaks ground in Sanmen, China. The reactor, expected to generate 12.7 Megawatts by 2013, costs 40 billion Yuan (~US$6 billion; that's a lot of iPods.) According to Westinghouse, 'The AP1000 is the safest and most economical nuclear power plant available in the worldwide commercial marketplace, and is the only Generation III+ reactor to receive Design Certification from the US Nuclear Regulatory Commission.' However, Chinese netizens suspect China is being used as a white rat to test unproven nuclear technologies (comments in Chinese)." Update: 04/20 07:28 GMT by T : As several readers have pointed out, this plant will generate much more than 12.7 Megawatts -- more like 1100 MWe.

12 Small Windmills Put To the Test In Holland 510

tuna writes "A real-world test by the Dutch province of Zeeland (a very windy place) demonstrates that small windmills are a fundamentally flawed technology (PDF of tests results in Dutch, English summary). Twelve much-hyped micro wind turbines were placed in a row on an open plain. Their energy yield was measured over a period of one year (April 1, 2008 — March 31, 2009), the average wind velocity during these 12 months was 3.8 meters per second, slightly higher than average. Three windmills broke. The others recorded ridiculously low yields, in spite of the optimal conditions. It would take up to 141 small windmills to power an average American household entirely using wind energy, for a total cost of 780,000 dollars. The test results show clearly that energy return is closely tied to rotor diameter, and that the design of the windmill hardly matters."

Rugged Linux Server For Rural, Tropical Environment? 236

travalas writes "Last year I moved to Rural Bangladesh. My work is pretty diverse, everything from hacking web apps to designing building materials. Increasingly a Linux VM on my MacBook Pro is insufficient due to storage speed/processing constraints and the desire to interface more easily with some sensor packages. There are a few issues that make that make a standard server less than desirable. This server will generally not be running with any sort of climate control and it may need to move to different locations so would also be helpful if it was somewhat portable. The environment here is hot, humid and dusty and brutal on technology and power is very inconsistent so it will often be on a combination of Interruptible Power Supply and solar power. So a UPS is a must and low power consumption desirable, so it strikes me that an Integrated UPS a la Google's servers would be handy. Spec wise it needs to be it needs to be able to handle several VM's and some other processor storage intensive tasks. So 4 cores, 8GB of ram and 3-4 TB of SATA storage seems like a place to start for processing specs. What sort of hardware would you recommend without breaking the bank?"

Robo-Arm Signatures Are Legal, Gov't Buys One 154

AndreV writes "It's endlessly comforting to know a recently designed and implemented long-distance robotic signing arm can produce signatures legal in both the US and Canada. The aptly named LongPen replicates the handwriting from a person writing in a remote location — with the unique speed, cadence and pressure of a human pen-stroke. It started as an idea from author Margaret Atwood to help free her from grueling, multi-city, multi-country book tours, but the hard stuff was done by a bunch of Canadian haptic gurus, whose design took into consideration many factors of the human arm and how we write. How it works: from the author-end, data protocols are set up, and the pen pressure is measured on a special tablet. The data streams to the robot, while algorithms smooth out all the missed points. Complex math operations were used to help the mechatronic limb repeat the hand's motions without unnecessary jerking, and programmers had to 'scale time' or 'stretch time' by breaking down the movements, essentially tricking the eyes into thinking the robot is writing fast. It was recently adopted by the Ontario Government to sign official documents. It helps criminals sign books, too."

Swedish Museum Puts Pirate Bay Server On Display Screenshot-sm 128

The Swedish National Museum of Science and Technology has put the server from The Pirate Bay on display. The server was confiscated in a police raid last year. The museum bought the server for 2,000 kronor ($240) from a member of the Bureau of Piracy, a Swedish group seeking the decriminalization of filesharing. "This is an object of contemporary society and a museum collects such items, and it is a part of our mission as a museum not to avoid complicated questions," curator Nils Olander said. The display is 98% complete and the museum staff has been waiting on a seeder since Thursday.

New Nokia Smartphones Leak E-mail Passwords 94

Noksu writes "Despite of the recent plunge in Nokia's profits, the company is doing well in the surveillance business. The infamous 'Lex Nokia' got ratified in Finland and the company has launched a massive Nokoscope research project for data gathering. In the meantime Nokia's new smartphones forward e-mail account credentials to a remote server. Surprisingly enough, this is done in HTTP request headers. The company has been informed, but there has not been an official statement yet. Time for class action suit in the US?"
