Don Stratton writes "This is the coolest thing I have seen anyone do with a Pocket PC... ever! Well-known Pocket PC developers SPB Software House, located in Russia, have come up with a very interesting spin on computing clusters. The short version is they connected 12 Pocket PCs together in the first known 'supercomputer cluster' of its type and had it calculate the old '3n + 1' problem. It was just done for fun, and not intended to seriously compete with desktop computers, but it does point out some interesting possiblilities for the future of handhelds with wireless connectivity working in ad-hoc computing clusters."

captain igor writes "According to this story on Wired News, a new company launched by researchers from Stanford has come up with a way to layer a silicon network of tiny tubes on top of a microprocessor. The system then uses a solid-state motor (no moving parts!) to pipe cold water through the silicon network. According to the article, this system can handle 1000 watts (yes, a kilowatt) per square centimeter."

goombah99 writes "The Detroit FreePress reports that Michigan state is planning the largest single laptop purchase/lease ever, over 130,000 wireless laptops--enough for every 6th grader. And of course future purchases for each new class. The main competion is between Dell and Apple, with Apple having the edge in classroom integration experience. But price points will matter since the school districts may have to pay $25 per pupil. And the Gates foundation has a foot in the door. No word on what OS the Dell laptops would run. What would be your choice for middle school classrooms with minimal sys admin?"

Dwight Schwartz writes "As reported in an article on the ScienceDaily site, researchers from Vanu, Inc. of Cambridge, MA, have successfully tested a system, the Vanu Software Radio(tm), that can replace a cellular tower's room full of communications hardware with a Pentium-based computer running Linux. The system offers the hope of making cellular technology more affordable for small, rural communities." The systems have been tested for the last several months in parts of Texas, with wider adoption planned for the near future.

kevinvee writes "Following an earlier Slashdot article, Yahoo is now reporting on the actual unveiling of Sony's PSX, with in-depth details on features and Japanese-specific prices for the 'hybrid gaming machine with digital media hub', which will start at $720 for the 160-gigabyte hard disk version." Japanese site Watch Impress has more pictures from the unveiling, including close-ups of the machine, and Digit Magazine explains specific features of this "hard disk, DVD digital video recorder and PlayStation 2 rolled into one", most notably that "...recording at 24 times normal speed is possible when copying previously recorded video... to a DVD-R optical disc", while GameSpot provides further analysis.

Jeff Bauer writes "Today's article in The Straight Dope explains all the weird keys that come with standard PC keyboards. Now if someone could just explain what the 'Alt Graph' key does on my Sun keyboard, enlightement would be at hand ..."

zetes asks: "For a while now I have been a supporter of a horizontal server architecture/environment, where one server does one and only one thing and a business/department would then have numerous servers. This way if a service needs to go down (especially in a Windows Server environment), nothing else is affected. However, due to the rising importance of security in the last couple of years, I have decided that having fewer servers is both easier to manage and update and also provides fewer points of entry for hackers or virus writers. I am not going to a purely vertical architecture, where everything is on one server, but more of a hybrid (down from 10-12 servers to around 5). So what I am asking you all today is what you prefer to support or manage? One or the other, or a hybrid? And does the operating system or particular service(s) dictate this architecture to a certain extent?"

lockdown asks: "How do I secure the files used in my department? I work in an engineering department and I've been tasked with securing our electronic files. We are a likely target of pirates, both internal and external. The 'resale' value of our files is very large. Attackers would be interested in selling our files or just posting them publicly for bragging rights. While I trust our engineers, many of whom have been here over 10 years, we do have many short-timers and temps in other departments. Worst of all, our IT department is clueless and even hostile to our efforts. (They are proud that, 'our network is so outdated that it can't be hacked.') How do I came up with a way to secure our files in a hostile environment and still get our work done?"

PoisonousPhat writes "NPR has an article on a new idea for concertgoers at the Aspen Music Festival. Dubbed the 'Concert Companion', the concept used a PDA (a Sony Clie PEG-NX73V for those of you that MUST know) as a 'listener's guide...that updates you with information about what you're hearing, in real time.' The concept seems similar to the audio headsets available in museum tours. Read the bleeping article here."

An anonymous reader writes "I just found this article which describes how a group of people in the UK built a 3 wheeled trike-type rickshaw to give visitors to a festival mobile Internet access. An interesting read for those /.ers into wireless networks, it also gives good information about the use of satellite for net connectivity and renewable energy sources. They do a good job of lightening a dry subject with a dash of humour." (The festival here is The Big Green Gathering, which sounds like a low-key, English version of Burning Man.)

Ruger writes "Reported in PCWorld this morning, IBM has introduced a technology for their new laptop hard discs which has a similar concept to airbags in cars. Active Protection System (APS) is a microchip put on the system board that senses acceleration. It parks the head of a hard drive inside a tenth of a second, significantly reducing the risk of damage to data. IBM also has a a press release on the new ThinkPad R50 and T41 models that include this technology, for those interested in the company line."

dafz1 writes "According to an article at CNET News, Motorola has announced they will create a new company from their Semiconductor Products Sector (SPS), which builds chips such as the PowerPC. Reasons cited include 'surrendering to IBM a key role in delivering the PowerPC for Apple Computer's top-of-the-line desktop'. This follows earlier news that Motorola's CEO will step down, citing a 'difference of opinion' with fellow executives."

Kurtis Kronk @TheTechLounge writes "Today we get a close look at perhaps the leader of this industry, ACR Data Recovery. I worked closely with Doug Roberts of ACR to find the answers to questions you might ask. Not only did I ask Doug an array of questions, I also received a sample of their Media Tools Professional 2003 to see for myself if it really works, and moreover, how well. Check out this article for the full story."

Filthmaster writes "I just saw an interesting paper that has been posted to bugtraq, full-disclosure and vulnwatch. It deals with the principles of stealthily using network infrastructure as either short-term or long-term storage. Not sure if I'm ready to implement it, but it makes interesting food for thought." There's also a mirror up.

mallumax writes "ComputerWorld has an exciting review of Apple's Dual 2GHz machine." An excerpt: "It's clear from two weeks of testing that Apple's new Power Mac G5 dual 2-GHz machine is the fastest thing the company has ever produced. And while you can debate benchmarks until eternity, it certainly appears poised to meet or beat anything now out on the Windows side."

chensonny writes "Recently I was in a situation where there was no word processor, and several of us had to write, copy and sign a big amount of paper. It was then I re-realized the need for a good and comfortable pen. I saw some friends using a Mont Blanc, others like me using a felt pen or cheap ball-point pen. What does the geeks of Slashdot use for writing?" My favorite pen is an aluminum Lamy fountain pen -- can anyone recommend a good place to order Lamy ink in the U.S.?

SteveOU writes "Lexmark won a favorable judgement in its attempt to prevent competitors from refilling its cartridges. The judgement, issued by Judge Saundra Brown Armstrong of the U.S. District Court for the Northern District of California, was a big loss for 'the rest of us,' reading in part "Because of its patents, Lexmark has the right to impose conditions on the sale of its patented product. It may restrict a purchaser's ability to repair it, which is what in essence the single-use condition does." What now? Will GM prohibit unauthorized repairs of its patented car components?"

mgcsinc writes "Yahoo is running a story on how some manufacturers of "USB 2.0" devices are making hardware compatible with the USB 2.0 standard, but not necessarily its high-speed component." Sounds like the complaint raised earlier this year.

An anonymous reader writes "Forbes has an article about the come back of Psion in the high end PDA market. Psion's OS, Symbian, that used to power their PDA (as the Revo for example, or the Series 3, or the Series 5), has been mostly used in cell phones lately, like the Nokia 3650. According to Forbes's article, the new Psion laptop/PDA, the Netbook Pro, will not be powered by Symbian OS, but by Microsoft CE.Net." prostoalex points out a ZDNet review of the device, "which is smaller than your usual notebook PC, but larger than a regular PDA. The product Web site contains specifications in PDF format. It's an Intel Xscale PXA255 400MHz, 128MB SDRAM and 32MB Flash, SVGA (800x600) device supporting CompactFlash and Secure Digital (usual for PDAs) as well as PCMCIA (usual for laptops)," and notes that despite the OS, "the specs list the presence of JEM-CE Java Virtual Machine."
