SpinnerBait writes "AMD took the wraps off their next speed bump with the Barton core, the Athlon XP 3200+. This CPU runs with a 400MHz Front Side Bus at 2.2GHz and is targeted at competing toe to toe with Intel's latest P4. The benchmarks and review over at HotHardware, look pretty good but Intel's 3GHz/800MHz FSB P4 variant seems to squeak past it here and there. Regardless, more of that "yin" to compete with Intel's "yang" was released today by AMD and consumers will benefit again from the competition."

Dr. Jackie Lee writes "Don't have the budget for an AMD Opteron? There's always a cheaper alternative with AMD's current Barton processors. In this article, we'll show you how to run these new Barton XP processors in SMP mode."

An anonymous reader writes "According to this article at LinuxDevices.com, Vanu Technology is demonstrating what it claims represents the world's first handheld 'software radio' using an iPAQ PDA running Linux at a conference in Washington DC today. Vanu apparently has implemented the signal processing functions on the iPAQ's XScale processor, and their software uses POSIX APIs to make it platform independent. Software radios implement multiple radio standards and frequency bands in software, rather than hardware. A standard iPAQ expansion pack houses the radio transceiver."

HardcoreGamer writes "Today ATI shipped its Radeon 9800 Pro 256 MB DDR-2 card in time for E3 and nVidia announced the NV35-based GeForce 5900 which will be available in June. Early tests seem to say that while nVidia edges ahead of ATI in specific areas, overall ATI still has the better card. The caveat is that the next generation of DirectX 9-based games (like Doom 3 and Half-Life 2, demonstrated with ATI at E3) will truly determine which is the better card. Lots of coverage at PC Magazine, PC World, The Register (ATI) (nVidia), ExtremeTech, InternetNews, and Forbes/Reuters. Either way, at $450-$500, serious gamers are about to get another serious dent in their wallets."

arhines asks: "I'm working on a little research project to figure out what the environmental cost of heavy technological reliance is, and want any suggestions Slashdot has for factors to consider. My school has started requiring students to own and use laptops in all of their classes, under the pretext of saving paper. Having read about the problems with computer recycling on Slashdot, I've become suspicious of the true effect of having several hundred computers thrown out each year. What statistics should I focus on, and are there any definitive studies on the topic you could point me to?"

inditek writes "At Stake has issued a security warning today about a vulnerability in Apple's AirPort Base Station: 'Apple's AirPort device is a wireless access point, providing 802.11 services to network clients. Authentication credentials are obfuscated, and then sent over the network. If an AirPort is administered over the Ethernet interface or via an insecure (non WEP) wireless connection, an attacker that can sniff the network can obtain administrative access to the AirPort.'"

NeoChichiri writes "News.com is running on an article about glitches in Intel's Itanium 2 chips. Even though it doesn't affect all chips, they have still stopped shipments of the new 450 Servers until the problem is resolved. Apparently it has to be 'a specific set of operations in a specific sequence with specific data.' Intel is saying that affects the 900MHz and 1 GHz Itanium 2 chips and that it will not affect the upcoming 1.5 GHz Itanium 2 6M chips." Until the next iteration of chip arrives though, Oliver Wendell Jones writes, "they recommend working around the problem by underclocking the processor to run at 800 MHz instead of its default 900 MHz or 1 GHz."

The Other White Meat asks: "I want to put a computer in my kitchen. For space reasons, I want to make it an LCD; a 15" screen would be perfect. This monitor is going to be exposed to harsh conditions (flying food, jumping cats, general mishandling). I don't want to spend so much money on it that if I came home and found it broken that I would be upset by it. I figured there must be plenty of places that will sell LCDs with dead pixels or columns, where I might be able to pick one up in the $50-100 range, but so far I have found nothing. Surely there must be a market for 'Grade B' LCD monitors, for precisely this sort of low life expectancy sort of usage? So fellow readers, can you succeed where Google® has failed, and lead me to the cheapo LCDs?"

cascadefx writes "O'Reilly's Hacks page has a really great article about a wireless access point that was on display at the recent Emerging Technology Conference. The folks at NoCat.net rigged up a Siemens Speedstream series access point with a low power ultraviolet light to create a wireless lightbulb. Just screw it in place and combine powerline ethernet with a wireless network... and a light, to create a wireless lightbulb. Ubiquitous networking, here we come."

elliotj asks: "With the widespread adoption of WIFI, I'm finding more and more places where I'd like to use the Internet on the road. All I really need is a linux command line to run SSH, links, and a few other things. What I'm looking for is a very lightweight subnotebook with a long battery life, quick sleep/wake times, that can run Linux and WIFI. I've looked at the Sony picturebook line and the Toshiba Librettos. Both are sweet machines, but have more features and are more expensive than I really need. Are there any cost effective options out there?"

AEton writes "There's an interesting article up at Newsforge, an OSDN sibling site, about price fixing in the DRAM market. According to Melanie Hollands, a technology analyst, market consolidation and uncertain prices have contributed to subtle cooperation between the major DRAM "competitors" to keep prices high. While she finds little "hard evidence of collusion", there are strong circumstantial trends which last year sparked a secretive Department of Justice antitrust inquiry." Allegations of this have been floating around for a while - heck, you can even join the suit.

Roland Piquepaille writes "Our computers are probably 10,000 times faster than they were twenty years ago. But operating them is much more complex. You all have experienced a PC crash or the disappearance of a large Internet site. What to do to improve the situation? This Scientific American article describes a new method called recovery-oriented computing (ROC). ROC is based on four principles: speedy recovery by using what these researchers call micro-rebooting; using better tools to pinpoint problems in multicomponent systems; build an "undo" function (similar to those in word-processing programs) for large computing systems; and injecting test errors to better evaluate systems and train operators. Check this column for more details or read the long and dense original article if you want to know more."

Makarand writes "Verizon has ambitious plans to catapult pay phones from the pre-cellular era to the WiFi era by creating hotspots around pay phones using an extension of their DSL service. The current plan is to upgrade 200,000 pay phones in the New York metro area to provide a WiFi service. Although major metros are spotted with hotspots, finding them is usually a big problem. Verizon thinks that specially marked WiFi enabled pay phones would solve the problem of locating the hotspots." Sounds similar to Bell Canada's move to do the same.

AltGrendel writes "Bored during those rush-hour traffic jams? An enterprising UK geek has installed an Xbox/Linux system in his car. With a mod chip, Freevo, a LogiTech Wingman, and a 40 gig hard drive, he has access to music, video, and games during drive time. Details and pictures are here."

fm6 writes "We can look forward to a round of niche devices running PalmOS. According to the Forbes article, we're looking at PalmOS in: a game device called Helix , a platform for developing 'customized handheld instruments' called the Meazura, and of course, the usual round of PalmOS cell phones. On the other hand, fewer manufacturers seem to show any interest in making general-purpose PalmOS PDAs. Food for thought."

DarklordSatin writes "Nature.com has an article up about new LCDs that are thin enough to roll up and can display black and white at 96 dpi. More coverage by Wired and Scientific American. Thanks go to Arstechnica for the heads up." Wow. Let the speculation for new uses begin! Update: 05/10 14:59 GMT by CN : Whoops, this is really a dupe of an older story that slipped through because I only searched for LCDs. Ah well, it's still cool.

Aavidwriter writes "Peter Wayner asks Michael 'Monty' Widenius of MySQL, 'When will RAM prices make disk drives obsolete for database developers?' From Monty's answers, it sounds like hard drives may be nothing but backups before long." From experience, I'd wager that RAM failure rates are less than hard drive failure rates, so it might also mean more stability from that perspective.

Michael B asks: "I recently bought an 8 port KVM to switch between various workstations and servers at home, and I'm realizing what I can't switch is audio! I've seen 4 port audio/video type switches (for things like switching between video console systems) but this doesn't address more than 4 ports and having the adding RCA/S-Video is a waste. I've thought of building one from scratch using Radio Shack parts, but can't find any info, such as a schematic, online. Does anyone have any ideas or sources of info for this one? Belkin seems to make a 4 port KVM with audio, which would be nice, but I need more than 4 ports. Thanks for any help!" After a bit of digging, I found this monster, which does 8-port KVM and audio, but that weighs in at a hefty $500USD, which is rather expensive. Has anyone managed to find schematics to such switchers so that folks, who aren't afraid of soldering irons, can build their own?
