Comment: I did this a little bit ago for fun. (Score 1) 205

by RazorRaiser (#38253004) Attached to: Ask Slashdot: Parallel Cluster In a Box?
For a portable case use a plastic footlocker, the kind with wheels and a hinged lid. This hinged lid was key for me as it allowed me to attach a keyboard, trackball mouse, and small monitor.

On the inside I have two ATX motherboards with dual core Athlon 64s, though I could have used anything had I felt like spending the money. The worker node has two graphics cards and an extra NIC for regular network traffic (the onboard gigabit NIC is used for message passing). The head node has an extra WiFi NIC as well for talking with the outside world. There are then two switches, one for each internal network, and two hard drives off the head node. The worker node boots off a USB stick. I found Ubuntu installed from a live CD provides a nice, small OS.

It's a little cramped (the top sides of the motherboards face each other), but there's enough room for the power supplies to divide the space down the middle, with the switches and hard drives mounted above that and opposite of one another. Everything is held in place with L brackets, plexiglass, screws and spacers. Between Newegg (computer hardware), Amazon (keyboard, mouse, and monitor), and the Home Depot (box and mounting hardware) the whole project only cost about $1,000.

What's really nice is that there's room enough in the box for four ATX systems with expansion cards, or probably eight-ten mini-ITX boards if you wanted to go that route.

If you haven't already, add these sites to your research:

They were extreemly valuable to me.

It won't be particularly easy, but it will be fun and rewarding like no other, and it makes a great mobile monster to show off to your friends!

Not sure if this has been discussed before, couldn't find anything through the search, but the news is that it's now "compatible" w/ Vista. Woohoo!!"

PurpleZebra writes "Thanks to the email-leakage from MediaDefender-Defenders we now have proof of the things we've been suspecting for a long time; the big record and movie labels are paying professional hackers, saboteurs and ddosers to destroy our trackers. While browsing through the email we identified the companies that are also active in Sweden and we have tonight reported these incidents to the police. The charges are infrastructural sabotage, denial of service attacks, hacking and spamming, all of these on a commercial level. The companies that are being reported are the following: * Twentieth Century Fox, Sweden AB * Emi Music Sweden AB * Universal Music Group Sweden AB * Universal Pictures Nordic AB * Paramount Home Entertainment (Sweden) AB * Atari Nordic AB * Activision Nordic Filial Till Activision (Uk) Ltd * Ubisoft Sweden AB * Sony Bmg Music Entertainment (Sweden) AB * Sony Pictures Home Entertainment Nordic AB"

+ - Exoskeleton gives soldiers strength with grace

Submitted by volpe
volpe (58112) writes "This video shows a robotic exoskeleton (not unlike the one used by Sigourney Weaver in Alien) being developed for soldiers. The wearer can lift large amounts of weight, but still retain pretty fine motor control, enough to play catch, gently box a punching bag, and dance. It's currently tethered, but will be deployed with a battery pack. I'd be impressed to see this thing capable of carrying a battery that can power it for any appreciable length of time, given the SWAP (Size, Weight, and Power) problems associated with the gear that soldiers currently carry, or are slated to carry in the near future."

+ - Virtual IT admin could be very real job->

Submitted by
Lucas123
Lucas123 writes "VMware and Cisco are increasingly pitching the idea of virtualizing the entire data center, which would enable the dynamic management of servers, storage and network devices through a single "fabric." That virtualization platform may spawn a new IT position for a person who would supervise the management of the virtual layer of the data center. The discussion gained momentum when Cisco and VMware announced an integration initiative between Cisco's VFrame Data Center and VMware Infrastructure 3, which is an appliance upgrade that fits into the Cisco's Data Center 3.0 vision. The combination would automate IT orchestration in the areas of server, network and storage provisioning for shops invested in Cisco hardware."

+ - Dislike a Relative? Turn Them in as a Terrorist! 9

Submitted by Stanislav_J
Stanislav_J (947290) writes "A Swedish man who had less than fond feelings for his daughter's hubby, took advantage of the son-in-law's trip to America by reporting him to the FBI as a terrorist. The e-mail, which the father-in-law admits to sending, earned him a libel charge after his poor son-in-law was arrested on his arrival in Florida, handcuffed, interrogated, and placed in a cell for 11 hours before being released.

It's a brief article, but dovetails nicely with the recent Slashdot story about "The War on the Unexpected." That article touched on many examples of well-meaning, but misguided and paranoid citizens reporting innocent activities to the authorities. In the current climate, the potential also exists for maliciously false and far from well-meaning reports made to the Feds about people one simply doesn't care for, or those made merely as a sick prank.

While the man admitted to sending the e-mail to the FBI, he claims he thought no harm would come from it because "he did not think the US authorities would be stupid enough to believe him." To quote the great philosopher Bugs Bunny, 'Nyahh....he don't know us very well, do he?'"

An authority is a person who can tell you more about something than you really care to know.
