They say they picked up their first image after walking half a block in NY city. X10's work on the same frequency as 802.11b. .. anyone want a combo WiFi/Video sniffer for Christmas?"

YingYang writes "With Intel's i875P (otherwise known as Canterwood) chipset launch a couple of weeks ago, we were shown what an 800MHz System Bus can do for performance of the Pentium 4. At the time however, there were few Taiwanese OEM motherboards out and test-beds used to showcase the new chipset and throttled-up P4, were based on Intel designed motherboards. Now however, the Canterwoods are beginning to flow out of Taiwan and vendors like Abit and Asus have put together boards with a ton of integrated features and performance, that reminds us of the days of the 'BX,' when Intel chipsets were the only way to fly. Check out this Abit/Asus Canterwood head to head comparison at HotHardware."

Radical Rad writes "There is a great article by Bruce Forsberg at Linux Gazette for anyone wanting to develop for the Zaurus platform. Using a mileage calculator as an example, he covers step by step setting up the Qtopia SDK, compiling, testing with the Zaurus emulator, and finally cross-compiling and creating the distribution package. He covers all the bases including compile-time environment variables and the control file for the ipkg."

Cutie Pi writes "On the heels of this recent Slashdot story discussing Wi-Fi use on airplanes, the BBC is reporting about new evidence indicating that cell phones can interfere with airplanes' navigation systems. From the article: "In tests, compasses froze or overshot, navigation bearings were inaccurate and there was interference on radio channels." Look like like Wi-Fi and airplanes just don't mix."

amateur radio buff writes "The Hamvention is coming up on May 16 - 18, for all you amateur radio people out there. This is the worlds biggest Ham fest held in Dayton, Ohio. With over 2500+ space outdoor vendor, and 500 inside exhibit spaces, find any amateur radio and electronic items there. Also the The 11th Annual Dayton Contest Dinner is held this year too! Dont miss it!"

WegianWarrior writes "Bruce Simpson, the man behind one of the more interesting site about pulsejets on the web, has launched a project to build a US$5000 DIY cruisemissile - just to prove that it can be done, since some said his earlier article about it was off the peg. Bruce has also designed and placed on his site a non-weld pulsejet you can build with simple tools, a 2D airflow modeling rig and a new valve/injector design for conventional pulsejets (according to the first page on his site, this new design is placed in the public domain)." We linked to his pulsejet pages about two years ago.

frisket writes "The history of computing is full of unsung heroes and heroines, their battles against disbelief, and the machines they created. This is one of those fascinating stories: the first real office computer, designed for business rather than science or research, and built from scratch by the British company of Lyons in 1949-51 -- whose primary business was their huge chain of tea-shops." Read on for more of frisket's account of A Computer Called LEO, which sounds not only like a good story, but also like a bit of comeuppance for tea drinkers in the coffee-obsessed tech world.

terradyn asks: "Recently, I've been looking for a cheap external storage subsystem solution. Aside from the fibre channel high end solutions out there (IBM FastT, HP EVA, etc.), I haven't been able to find much for the SOHO type market. My current best possibility is this. It provides the capacity and interface type I was looking for (8 bay, ATA6, 1394) but lacks features like RAID5 or NAS type abilities. Has anyone found a better solution with at least RAID5 in a similar or smaller form factor for use in the home (I need the space/speed/reliability for video work)?"

Anonymous Coward asks: "Has anyone at Slashdot has heard of or used the Quill Mouse? It's an odd shaped mouse that's supposed to reduce repetitive stress injuries like Carpal Tunnel Syndrome." Rather than grabbing and moving the Quill mouse with your hands, you rest your hand in the Quill's "nook" and move the entire assembly with your arms. Since the palm of your hand is facing inward, you can then click the buttons which have been rotated to match the "nook". The web page says this hand position is less likely to cause RSI than the position a standard mouse requires. Anyone with (or who have used) a Quill Mouse care to comment?

An anonymous reader writes "A ten month torture test of five LCD and two DLP projectors shows LCD images deteriorate during extended use." Not surprisingly, if you run an LCD projector for 4000 hours, it deteriorates... of course, if you're staring at a projecter 8 hours a day, for 500 straight days, maybe you should go outside ;)

Condo-Netwerk asks: "I'm trying to prepare a proposal for my condo building to be our own DSL provider. With 160 units, we should be able to get a T1 and keep the price fairly low. But what's the up-front cost? Which hardware should we use? What do we need to know about Copper Mountain, Avidia, etc. to do our due diligence prior to selecting hardware? I'm also helping a friend spec cabling for a new 30-unit condo building he's putting up; he wants to pull cat5 and split a DSL line from the phone room to each unit. Caveats? Experiences? Is it better to use cat6 or fiber?"

goofrider writes "Sanyo introduced a new format called HD-Burn, supported by their new DVD+/-RW chip. It allows the drive to burn up 1.4GB of data using a regular 700MB blank CD-R blank. The resulting HD-Burned CD-R can only be read by supporting DVD/DVD-ROM drives and CD-ROM drives. Most DVD/DVD-ROM drives can support the format via a firmware upgrade. It's unclear how easy and how likely will it be for future drives to support this format. In contrast, Plextor released their new GigaRec technology in their new PlexWriter Premium (read a review here). GigaRec also records on regular blank CD-Rs, allows up to 1GB of data on a 700MB disc. however, the disc can be read on any modern good-quality CD-ROM drives with no firmware upgrades required. So now I can record 2x the data on a CD-R but I still can't have filenames longer than 64 characters. :)"

Anonymous Howard writes "This article talks about Sony's new, limited production Vaio GT3/K. It's a mixture of laptop and full fledged camcorder that uses the Transmeta 600mhz Crusuoe chip. Weighing in at 2.4 lbs, this hybrid has an amazing battery life of up to 17 hours, 30 GB drive, ATI Rage Mobility-M1 and 128 MB of RAM, and a swiveling screen. This is definately a very unique device, one that completely blows away Sony's previous attempts of the laptop/video combination machines, mainly due the fact that the video camera is not a wimpy little video lense, but an actual full fledged digital camcorder."

EconolineCrush writes "Tech Report has a great in-depth review of NVIDIA's budget GeForce FX 5200, which brings full DirectX 9 support down to an amazing sub-$70 price point. Any budget graphics card capable of running NVIDIA's gorgeous Dawn is impressive on its own, but when put under the microscope, the GeForce FX 5200 looks more like an exercise in marketing spin than a real revolution for budget graphics cards."

glesga_kiss writes "Actuality Systems have issued a press release announcing sales of their 3D display technology, as reported by Yahoo Finance. The system works similar to an old spining disk optical illusion, except that the 21st century version produces an image that can change through the use of digital projection. In this case the screen is a rotating disk that is capable of producing light at any point that it passes through. The upshot is that you get a real 3D representation of your object, that can be viewed from 360 degrees around the display, without the need for any special goggles. Not quite ready for Hollywood, but the scientific and engineering communities have some obvious uses for it already..."

JadeSky writes "Having played around with wireless networking at home a little bit, and then being faced with implementing a wireless network at the office for the purposes of in-house customer training in a cosmetically clean room (wires are ugly), I had been thinking for some time about the best way to implement a secure wireless networking solution. Amusingly enough, shortly after the idea of a wireless network at the office came up, I managed to win 802.11 Security in a raffle at the Kernel Panic Linux Users' Group monthly meeting. The book was thoughtfully donated (with a few others) by O'Reilly on the condition that the recipients contribute reviews. Since I've found the book genuinely helpful, I thought I'd let others know, and hence, my first Slashdot book review. Hooray!" This book emphasizes a multi-layer approach to wireless security; read on for more of JadeSky's review.

grugruto writes "Cluster of databases is no more the privilege of few high-end commercial databases, open-source solutions are striking back! ObjectWeb, an Apache-like group, has announced the availability of Clustered JDBC (or C-JDBC). C-JDBC is an open-source software that implements a new concept called RAIDb (Redundant Array of Inexpensive Databases). It is simple: take a bunch of MySQL or PostgreSQL boxes, choose your RAIDb level (partitioning, replication, ...) and you obtain a scalable and fault tolerant database cluster."
