iMac Beowulf Cluster Comes to Life 56

AmigaAvenger writes "Finally a good use for all those old IMacs that many organizations have laying around collecting dust. We have set up a 5 node (4+1 controller) iMac beowulf cluster, which is appropriately named Skittles, and is running PPC Yellowdog Linux, with MPICH 1.2.6 cluster message passing software."

Sensibly Powering DC Technology? 90

splatnet asks: "Having upgraded my PC to a Mac Mini all my IT kit is now DC. The Mini, my flatscreen, external USB HDD, USB DVD writer, JBL speakers, ADSL/Wireless Router. I have practically the same amount of space taken up for transformers as I do computer equipment! Has anyone found/invented a way to power multiple DC devices (all with slightly different power requirements)? I'm thinking in terms of space/convenience/running costs etc." It would be neat if there was a DC power source that could be tuned to a specific voltage, as well as modular plugs to fit your various devices. Is there anything out there that comes close?

Homemade EVDO/WiFi Mobile Access Point 172

Tamundson writes "Over the last few weeks I've built myself a mobile access point for my car. It's based on a Soekris net2421 embedded Linux box and uses Verizon's 1xRTT/EVDO network as its uplink, resharing it over 802.11b. Wherever my car goes, my Internet link goes! :) I finally put some webpages together on how I built it. The components are pretty cheap and anybody with basic Linux skills can build their own just as easily. I've also got it interfacing with Google Maps to do live vehicle tracking via gpsd. It also uploads pictures from an on-board webcam every five minutes or so."

Nintendo Revolution Under Wraps Past E3 741

The next-generation Nintendo console, codenamed Revolution, may not be shown at this year's E3. Eurogamer reports that the Japanese console maker is going to keep the console under wraps to keep the features of the new system out of the limelight a little while longer. From the article: "Nintendo boss Satoru Iwata is worried about rivals nicking all his best ideas at this early stage. That's how revolutionary the new console is, apparently... and also the exact same line Nintendo used to avoid showing Mario 128 at a previous E3."

Mac Sync Finally Comes to the Danger SideKick 37

drenalin writes "After many months (years for some early adopters) of waiting, users are finally able to see the light of day for Markspace's, MissingSync for the HipTop. This is an iSync conduit which allows users to sync their calendar and address book over the Internet to their SideKick from T-Mobile. For many Mac users this is the one feature that now finally makes the SideKick a nearly perfect device."

Robotics/Electronics Class - How Would You Do It? 58

MainerDood asks: "I have been teaching programming and networking at the high school and collegiate levels for several years, and now I am branching out into electronics and robotics for my high school students. I am keen on Linux and Open Source solutions where feasible, and would like to avoid using pre-packaged robotics/electronic 'kits' (ie: Lego Mindstorm). I have a minimal budget, like to tinker and have access to tons of old PCs... I would like to use them in these projects and buy the 'parts' where needed. I am envisioning an order of breadboards, diodes, resistors, etc. but not sure from where I should order, what a good basic startup setup should contain and resources I should refer too. I have found a bunch of links online and various resources, but I am curious to know how you would go about this... seasoned veterans and electronics/robotics enthusiasts - I am all ears!"

The Bender PC Case 239

malorkus writes "This Norwegian site details the process of building an awesome Bender (from Futurama) case mod, complete with an Optical drive in his mouth that you slot CDs into! (Be sure to click the link at the bottom of the page to see the next page in the sequence)." This is one of the most impressive DIY cases I've ever seen. Props to the artists behind this one, even if I can't read any of your words!

Firms Get Away with Selling Untested DRAM 344

peppytech75 writes "Melanie Hollands in IT Manager's Journal reports that 'In recent months, some Asian DRAM memory manufacturers have been getting away with selling untested ("UTT") DRAMs. Disturbingly, the practice seems to be getting traction at the lower portion of the module business. This is being done mostly by Taiwanese DRAM makers, who are undercutting the tier-1 guys by selling untested and unmarked parts.' What's the solution here? Or is there an actual solution to what amounts to pirate companies issuing counterfeit parts?" (IT Manager's Journal, like Slashdot, is part of OSTG.)

Microsoft to Release a Thin-Client Windows XP 349

repking writes "I'm reading on Brian Madden's Thin Client Web that Microsoft is about to release (don't know exactly when) two new versions of Windows XP targeting the thin-client market (This products ARE NOT the Lite XP versions that Microsoft is about to release on certain countries like Brazil). Codenamed Eiger and Mönch, these two new releases would let you 'convert' old PC into thin-client Devices. Is Microsoft trying to compete with open source projects like PXES or ThinStation?"

Dell Still Intel Only 399

wyckedone writes "Dell Computers has no plans to offer the new dual-core AMD Opteron even though it has been proven that "Opteron's integrated memory controller and multiple Hypertransport interconnects help it outperform Intel's Xeon processor on many benchmarks, especially those that measure the performance of memory-intensive applications.". HP, IBM and Sun Microsystems have all announced that they are going to release servers based on the new AMD chip. Why not offer customers an alternative that has better performance instead of risking the lose of those customers to another vendor that does? Intel has no plans to release a dual-core Xeon until 2006."

Intel to Release WiMax Chip 104

david writes "According to CNET News, Intel plans to release their first WiMax chip on Monday. 'The world's largest chipmaker sees in WiMax a potential profit source that it hopes will become as popular as its shorter-range cousin, Wi-Fi. Intel also believes it will stimulate computer sales in emerging markets where high-speed Internet access is unavailable or prohibitively expensive.'"

Sterling D. Allan writes "Pure Energy Systems News (PESN) reports that GlobeTel Communications Corp. debuted their Sanswire Stratellite last week to over 300 people, including members of the media, personnel from the U.S. Department of Defense, U.S. and international commercial interests, as well as investors and shareholders. Stationed in the stratosphere, well above the jet stream, powered by film solar photovoltaic units, the device will make wireless communications available anywhere in the U.S., including on airline flights. One Stratellite will have a payload capacity of several thousand pounds and clear line-of-sight to approximately 300,000 square miles, an area roughly the size of Texas."

Best Motherboard for a Large Memory System? 457

kimanaw writes "Due to a particular infrastructure need, and increasing OS support for 64 bitness, I'm looking into building a large memory server box (at least 16 gigs, possibly up to 64 gigs, probably config'ed into a big ramdisk). I only need a single CPU, and just minimal disk; most prebuilt systems w/ large memory seem to focus on more CPus and big RAID, all of which (over)inflate the pricetag. I've searched several websites (including Tom's Hardware), and I've googled, but can't seem to locate any commercially available AMD MBs supporting more than 4 sticks of RAM, or 4 gigs. Have any Slashdotters built a big-RAM server? Any pointers, hints, and tips much appreciated."

Multi-layer LCD Displays 100

Jmo writes "Puredepth has started to produce multi-layer LCD displays. They manipulate LCD technology so that one screen can be placed behind another for actual depth. This technology has not even come close to being fully taken advantage of but it is still very interesting and has many implications for the future. Their main product right now is a seventeen inch monitor, the MLD-3000. It is mainly targeted at medical and business fields but it could be used all over."
