Multithreading - What's it Mean to Developers? 357

sysadmn writes "Yet another reason not to count Sun out: Chip Multithreading. CMT, as Sun calls it, is the use of hardware to assist in the execution of multiple simultaneous tasks - even on a single processor. This excellent tutorial on Sun's Developer site explains the technology, and why throughput has become more important than absolute speed in the enterprise. From the intro: Chip multi-threading (CMT) brings to hardware the concept of multi-threading, similar to software multi-threading. ... A CMT-enabled processor, similar to software multi-threading, executes many software threads simultaneously within a processor on cores. So in a system with CMT processors, software threads can be executed simultaneously within one processor or across many processors. Executing software threads simultaneously within a single processor increases a processor's efficiency as wait latencies are minimized. "

Build Your Own Bluetooth Sniper Rifle 309

Jim Buzbee writes "I don't think I'd do it, but these guys built a Bluetooth Sniper rifle, went to the roof of a downtown Los Angles skyscraper and pointed it at nearby buildings. See what they found, and if you're so inclined, they'll show how to build your own and maybe, just maybe, you too can snag Paris Hilton's address book." (Which was not snagged via Bluetooth snooping, as the article points out.) This version looks a bit more polished than the one mentioned last August.

CeBIT 2005: SLI Shuttle Surfaces 91

Kez writes "You wouldn't think it could be done, but you can actually fit two high performance video cards into a Shuttle XPC and run them in SLI mode. Shuttle are being a bit coy about the whole affair, despite the fact that they have the system on show. As such, no internal photos are available, but HEXUS.net has a writeup explaining what's inside."

'Millipede' Prototype Shown at CeBIT 156

neutron_p writes "It was a subject of much controversy for last 5 - 7 years, but it's finally got protyped. At CeBIT, IBM for the first time shows the prototype of "Millipede" - nanomechanical data storage device. Using revolutionary nanotechnology, scientists at the IBM Zurich R&D Lab, Switzerland, have made it to the millionths of a millimeter range, achieving data storage densities of more than one terabit per square inch, equivalent to storing the content of 25 DVDs on an area the size of a postage stamp. The principle of operation is comparable with the old punch cards, but now with structural dimensions in the nanometer scale and the ability to erase data and rewrite the medium."

DARPA Grand Challenge Teams Submit Videos to DARPA 93

doughnuthole writes "The deadline for DARPA Grand Challenge teams to submit their videos to DARPA just passed and some have posted them online. Some of the teams with these videos posted are Team Caltech, Axion Racing, Virginia Tech (on the Media page), Insight Racing, and UMass Dartmouth. The Grand Challenge is a 175 mile race run by fully autonomous vehicles. Since no teams completed the 2004 race, DARPA decided to run it again, this time for $2 million."

Mac mini in a Volkswagen 346

pyramis writes "Matt Turner has installed a Mac mini into his Volkswagen as an integrated audio/video system. He's distributed the I/O ports around the cab for convenient access and installed a remote power button right into the dashboard. Cool pics of all of this, plus a detailed article on that cool power button."

Nero Burning for Linux 599

ceasol writes "The German company Nero, developers of the award-winning Nero Burning ROM suite for Windows, now release a free version for Linux called NeroLINUX a CD/DVD Burning Software, and include many features from the Windows version. This software is proprietary but free if you registered." The OEM versions of Nero that come with many CD burners aren't sufficient, though; NeroLINUX is free-as-in-beer only if you've registered "a full version of Nero software version 6 or higher," or a "retail version or downloaded version."

How Do You Store and Reconcile Email Archives? 380

heyitsjustme wants to know how you deal with old email. "I delete most of what I get but keep the stuff from friends and relations as an archive. Unfortunately I have these email archives from the late 80's through today in the form of macintosh, linux and windows mailboxes including AOL 1.0 mailboxes. What does everyone use to archive email across multiple platforms and non-standard mailbox formats? Is there an easy solution out there? Does anyone archive IM?"

Do XML-based Databases Live Up to the Hype? 105

douthitb asks: "I have recently started work as a contractor with a company developing/improving an application for exchanging large amounts of data. The current solution exchanges data via XML, but the data itself is stored in a SQL Server database. There is a concern about the overhead involved with wrapping and unwrapping the XML to get the data in and out of a relational database. The proposed solution is to use Tamino, an XML-based database. Neither I nor any of the other developers have any experience with Tamino, but the desired result is to remove the bottleneck of converting the XML back and forth. Does anyone have experience using Tamino (or any other XML-based database)? What benefits and/or difficulties did you have in using an XML database, as opposed to its relational counterpart? How large of a learning curve should be expected with a product like this? Do XML databases really live up to the hype? A similar topic was discussed on Slashdot way back when, so I was hoping to get some more up-to-date feedback on the subject."

Repurposing Old Usable Cell Phones? 87

zentogo wonders: "As I stroll through the local recycle shops in my little Japanese City, I see boxes of used KEITAI-- Japanese Cell Phones. Most of them only a two or three years old, with more technology and features than any affordable phone in the USA, and they actually work! See, Japanese people cycle to new technology, especially phones, very quickly, and it is almost impossible for them not to. Take my own personal example: after one year with the telecom KDDI, I was given a free phone. It had more features than my previous one, and was much lighter, so when I was offered the deal I changed on the spot! So I wonder, what can be done with all these old phones? Can they be recycled for parts or even software? Can they be adapted to another type of technology? It would seem to be a big waste of decent hardware if something interesting couldn't be done with them."

AMD and Intel CPUs Supported On Same Motherboard 212

Kez writes "We haven't seen AMD and Intel CPUs since Socket 7, but ECS have created a motherboard sporting both Intel LGA775 and AMD 939 sockets. An Intel chip will sit in the board itself, whereas an AMD chip can be used through a daughterboard. HEXUS.net has the scoop from CeBIT." While this is pretty slick, I do wonder who is actually gonna buy this board in place of their usual favorite, since it's not like people are swapping their processors around every chance they get, unless they don't actually use the computer they've built.

The Nintendo Keynote In Depth 105

An event anticipated all week by many of the conference attendees, the Keynote delivered by Nintendo President Satoru Iwata was informative and inspiring. He spoke early on Thursday morning to a packed room that broke out into pleased applause several times during the speech's delivery. His talk spoke of the future, Nintendo's vision, and a commitment to reaching out beyond the current crop of game players to folks beyond the hardcore. Read on for a bevy of coverage and my own commentary on the "The Heart of the Gamer". (And some Zelda footage, if you care about that.)

Via Now Shipping Dual-Processor Mini-ITX Board 304

An anonymous reader writes "Via is now shipping its first dual-processor mini-ITX board. The DP-310 features two 1GHz processors, gigabit Ethernet, support for SATA drives, and a media-processing graphics chipset. It targets high-density applications -- according to Via, a 42-U rack with 168 processors would draw about 2.5 kilowatts, or about as much power as two hair dryers." This also looks like the basis for a nice car computer. Also on the small-computing front, an anonymous reader submits "General Micro, meanwhile, last week released what it calls the world's fastest mini-ITX board, powered by a Pentium M clocked up to 2.3GHz.
