d00dman asks: "I work for a colocation reseller. We don't own our datacenter, we lease cage space and with it we get an array of 30amp and 15amp power circuits. My problem is, inside of the cage we need to do our own power distribution. We have around 50 hosts in the facility, and are growing quickly. We need to add another 20 or so hosts in coming month. We are looking for a simple, scalable, and even power distribution method. As always, money IS an object. Right now we have a group of UPS's with power strips plugged into each. While this was sufficient for as many as 30 hosts, its starting to become a bit of a mess. Does anyone have any advice to offer...any creative tricks?"

(H)elix1 asks: "Without using an inverter, what is the good cheap way to power an ATX motherboard from a DC source? I have a mini-itx based computer I'm looking to use in the car and house. I'm looking for something like a laptop uses, with an AC-to-DC brick that feeds a DC-DC internal connector. Linitx.com has one, but it is a bit pricey after shipping to this side of the pond, googling turned up even more expensive industrial PSU's. Am I missing a simple hack? I have a soldering iron and am not afraid to use it..."

WeakGeek writes "Unstrung has a story talking about a security issue with the combining of 802.11 and GSM/GPRS networks. Seems that 802.11b hotspots provide hackers with an easy way to grab user information from the wide-area network itself. Back when GSM was being defined, standards were designed to only authenticate the details held on the SIM card in a user's device before starting a session on the network. The user's device doesn't in turn check the credentials of the network. Fake a network, get data. Of course, the linked to story seems to be a 'viral' advertisement for a product that fixes this, but I still thought it interesting enough to share."

nikitin2k writes "A swedish guy did a really sweet xbox mod. He moved the whole thing into an aluminium chassis, changed the dvd and hdd, installed a mod-chip, wireless lan, leds, switches and Linux. Meet the xXx-box. The site is in swedish, but the pics speak for themselves. Lots of pictures here." I gotta ask tho, at what point would it have made more sense just to buy a regular computer? The green lighting is a nice touch tho.

Play MP3s or DVDs, command Keynote and PowerPoint presentations, all from your Sony Ericsson Bluetooth phone. Nifty proximity mode lets you pause your music when you leave the room and automatically resume when you re-enter." It uses AppleScript, to control whatever AppleScript can control.

develop writes "Some folks from Israel have created a computer that runs on DNA and enzymes and is supposedly 100,000 times faster then today's PCs. Information at National Geographic, Telegraph UK and United Press." According to the National Geographic story, this DNA-based computer "can perform 330 trillion operations per second, more than 100,000 times the speed of the fastest PC." However, be aware that most of this is still future tense, and what these researchers have now is just a proof-of-concept.

Rorschach1 writes "Many /.'ers are already familliar with APRS, the Automatic Position Reporting System that's been mentioned here numerous times, most recently in the article on the Linux-powered weather balloon. It's one of the coolest things going in ham radio these days, but the APRS message protocol itself is rather hairy and bloated, and suffers from a distinct lack of extensibility. The OpenTRAC project aims to fix it, but we need your help." Read on to find out the details of what sort of help they're looking for as well as some more information about the project generally.

Java World is featuring the first part of a series comparing J2ME and the .Net CF vaporware (ok, it will exist at some point). It does tout the normal Java "features" such as being cross-platform in comparison to the mono-platform reality of .NET CFF. It has a bizarre critique of .Net CLR for being object oriented, and mentions the fact that most of the Linux PDAs coming out now run Java as an advantage for Java. (I love my Zaurus but I can't imagine it being useful for most people.)

andori writes "CNN is running a story about how WiFi is enabling low-income residents Internet access. The project is set at a public housing development in Boston, Massachusetts. Residents buy the WiFi NIC, and the access if free. It is nice to see people making an effort to expand the reach of the Internet to a broader audience."

babycakes writes "Interesting article over at the BBC about the future of wireless networks. Researchers at Intel are developing mesh networking technology that automatically organizes the best routes between wireless devices for better bandwidth control, now that the number of wireless devices is set to explode." Neat stuff, but they've yet to implement any sort of security controls. Until they do, it's going to be a real party for wireless eavesdroppers. timothy adds: La Camiseta writes "Wired has an article discussing the extent that some people will go to in order to stay connected. My favorite is their 4-way SMP system that fits into a briefcase."

Emmettfish writes "According to this release on Xiph.org, it looks like the Neuros player will support Linux users, and also give them the ability to play back Vorbis files on the move, starting in late May. Go Ogg! Remember, donating a few bucks to Xiph may not make the world a better place, but it'll definitely help it sound a lot better." For those of us craving a portable that plays from cheap CD-Rs rather than flash media or a hard drive, Emmett says by email that an agreement for development of firmware for a CD-based Ogg player is in the works, too.

An anonymous reader writes "ExtremeMhz.com has released an article on how they designed and built a PC containing dual systems. One system is a supercooled Intel and the other is a water chilled AMD. This PC features Dual SCSI storage subsytems also. Looks like some crazy stuff." Now if only they could put a mac and a PC in one case ;)

It also uses a Garmin GPS, HAM packet radio, an automated Aiptek Pencam Trio digital camera, army surplus batteries, and lots of geek duct tape."

mpath_lamp writes "Today Apple issued an exchange program for all owners of the Mirrored Drive Doors Power Mac G4. It's meant to resolve the incredibly loud fan noise in the current power supplies of Power Mac models that began to ship in August 2002. The program requires a $20 shipping charge and the return of the old power supply. Apple will begin shipping the kits on March 10 in limited quantities and the kit consists of a 360-watt power supply, system fan, allen key, and installation instructions. A big thank you can be directed to the guys over at G4noise.com for the continuous support in trying to get an official response from Apple."

dfung writes "This has been mindlessly discussed many times before here, but Western Digital has now introduced real enterprise-class ATA drives with SCSI-like performance specs and 30% lower price. So now you can buy a real 10K rpm ATA drive. Interestingly enough, they mention the reason for the traditional difference in price between ATA and SCSI which I never have seen mentioned here - it has to do with testing costs, not controller electronics|platter quality|etc. Another interesting tidbit is that 160 million ATA drives were sold last year. I saw about 2 million of them stacked up in the aisles at Fry's Electronics yesterday, but that sure is a lot of drives."

Ninja Master Gara writes "While this article shows Phoenix expanding the uses of the bios, ZDNet UK reports Intel is looking to get rid of it altogether, to be replaced with the Extensible Firmware Interface (EFI) as announced at the Intel Developer Forum. EFI promises a considerable amount of flexibility to system control and startup, legacy support, and programability. And it gets rid of text mode only start up too."

chowbok asks: "My grandmother recently had a stroke, which left her with the inability to speak or move the right half of her body. It also seriously impaired her motor skills on the half she can move, so she can't write. She does understand what is said to her, but she has no way to communicate. I'd like to set something up for her so that she can write notes. What I have in mind is a keyboard with rather large keys (perhaps 2" square) and a screen or monitor of some sort. I'm sure they make such stuff specifically for stroke victims, but anything labeled 'medical' will undoubtedly be astronomically expensive, even if it is a rather simple device like what I have in mind. I thought it would be easier to build one or find something similar (perhaps a toy or some such). I thought Slashdot readers might have some good suggestions along these lines. I'm not totally against doing it with a computer with a modified keyboard, but that seems like overkill when all I want is really a 'video typewriter'. Has anyone seen anything that might work for my purposes, or might serve as a good starting point?"
