It's obviously not for everybody, but at least Antec is trying out something relatively new for hard-core users. Not sure if you'd need an air spray can to keep the dust off all the components, though ..."

teddaw152 writes "I've been tasked with ordering an oscilloscope and a logic analyzer for use in a university physics lab, and have found several models that will likely suit our technical needs from the major manufacturers (Agilent, Tektronix, and LeCroy). However, I personally have only used legacy HP scopes, and thus I have no idea what modern features are must haves and which brand's user interface is the most intuitive. Is there anyone out there that has used modern Tektronix/Agilent/LeCroy scopes side by side and can comment on their thoughts from the purely subjective side?"

Wellington Grey writes "Daylight saving time almost upon us. The arguments about its possible benefits and drawbacks come up twice every year. Does it save energy or lives? Possibly, but it does definitely cause a great deal of inconvenience. My question is this: what do you think would be the best possible system to replace DST with? What is the best way for humans to deal with the inconsistent amount of light over the year and still foster coordination over disparate time zones?"

Hugh Pickens writes "Laura Holson writes in the NY Times that she 'wandered down to the T-Mobile store at Ninth Ave. and 43rd St. in New York City to see what kind of crowds — if any — were lining up to buy the new T-Mobile G1 which went on sale Wednesday' and saw no lines out the door, no crowding at the counter, and a complete lack of crowds. The iPhone appears to still be the gold standard and Etan Horowitz writes that the G1 'doesn't do a great job showcasing its potential. It isn't as intuitive as the iPhone, and it may take average users a while to figure out basic and advanced shortcuts and features' and 'may appeal more to techies who value open-source products and don't mind a somewhat steep learning curve.' Part of the reason for slow interest may also be that T-Mobile's 3G high-speed data network won't be up and running in many cities until the end of the year."

sneakyimp writes "My brother is an architect and sculptor and wants to create kinetic sculptures powered by wind, steam, and sun. He wants to avoid electrical systems and keep this mechanical. He's prepared to cast metals for custom parts if necessary, but is hoping to find a cheap source of gears, axles, and bearings for the internal mechanical workings of these contraptions. We'll need things like miter/bevel/spur/helical gears, standard and thrust bearings, and axles." Read on below for more on the details of what sneakyimp is looking for — dismembered Capsela units won't do it.

Maximum Prophet writes "When I was in High School, I built an X-Ray machine that (probably) didn't produce any X-Rays. I used an old vacuum tube and high voltage. Little did I know that simple triboluminescence would have enough energy to do useful work." The catch: you'll need to peel your tape in a vacuum, and have the x-ray film at the ready.

Lally Singh recommends a ZDNet piece predicting the imminent demise of RAID 5, noting that increasing storage and non-decreasing probability of disk failure will collide in a year or so. This reader adds, "Apparently, RAID 6 isn't far behind. I'll keep the ZFS plug short. Go ZFS. There, that was it." "Disk drive capacities double every 18-24 months. We have 1 TB drives now, and in 2009 we'll have 2 TB drives. With a 7-drive RAID 5 disk failure, you'll have 6 remaining 2 TB drives. As the RAID controller is busily reading through those 6 disks to reconstruct the data from the failed drive, it is almost certain it will see an [unrecoverable read error]. So the read fails ... The message 'we can't read this RAID volume' travels up the chain of command until an error message is presented on the screen. 12 TB of your carefully protected — you thought! — data is gone. Oh, you didn't back it up to tape? Bummer!"

theraindog writes "More than a year and a half after the first terabyte hard drives became widely available, Seagate has reached the next storage capacity milestone. With 1.5 terabytes, the latest Barracuda 7200.11 serves up 50% more capacity than its peers, and at a surprisingly affordable $0.12 per gigabyte. But Seagate's decision to drop new platters into an old Barracuda shell may not have been a wise one. The Tech Report's in-depth review of the world's first 1.5TB hard drive shows that while the latest 'cuda is screaming fast in synthetic throughput drag races, poor real world write speeds ultimately tarnish its appeal."

rsk writes "It's official: Google has Open Sourced Android. The source code can be downloaded from Android's Git repository. Bugs are handled at the Google Code Android project page with documentation being handled by a collection of Google Site pages. One of the more interesting aspects of Android seems to be the seemingly Eclipse Foundation-like organization of the project, welcoming both Individual and Commercial developers into the Android development pot. One of the benefits of this arrangement is securing the existence of the project by involving commercial interests and their money in the process ... this is also one of the downsides; having commercial entities charter and lead features of a platform that their own commercial offerings provide 'enhanced' versions of, sometimes leaving the free offering always lacking in one obvious way or another. It's hard to say at this point how involved Google will be in this process, or the Open Handset Alliance in general, with managing the health of sub-projects under the Android umbrella as time goes on."

ocularb0b writes "Cray has announced the CX1 desktop supercomputer. Cray teamed with Microsoft and Intel to build the new machine that supports up to 8 nodes, a total of 64 cores and 64Gb of memory per node. CX1 can be ordered online with starting prices of $25K, and a choice of Linux or Windows HPC. This should be a pretty big deal for smaller schools and scientists waiting in line for time on the world's big computing centers, as well as 3D and VFX shops."

1sockchuck writes "Microsoft and Google have opened a new front in their battle for global domination: data center energy efficiency. Just weeks after Google published data on the extreme efficiency of its previously secret data centers, Microsoft says it has achieved similar results with shipping containers (despite Google's patent) packed with up to 2,500 servers. The geeky benchmark for the battle is Power Usage Effectiveness (PUE), a green data-center metric advanced by The Green Grid. Microsoft says its containers tested at a PUE of 1.22, while Google reported an average PUE of 1.21 for its data centers, which apparently are also now using containers."

cookiej writes "We just completed having our basement gutted and our house decontaminated from mold. The finished basement is gone, my office floor has been removed as well as 24' of drywall around the base of the room. So, we had a full home theater downstairs along with a couple of computers in the electronics closet that were completely immersed (rainwater, not sewage). We moved them to a sheltered area outside and covered them with a plastic tarp. Since the electronics were off when the water hit them, 1) do I have a chance of recovering them? 2) If so, is there a way to clean them with some sort of liquid bath that would not damage the electronics? and 3) I don't want to bring moldy pieces back in the clean house. How could I decontaminate the electronics themselves, pre-bath? Not looking to save the speakers, just the amp, DirecTV box, video switch, etc. Thanks for any help, here, Slashdot."

Hugh Pickens writes "Traditional peak power hours — the time during the day when power demand shoots up — run from 4 p.m. to 7 p.m. when air conditioning begins to ramp up and people start heading for malls and home but utilities are now seeing another peak power problem evolve with a second surge that runs from about 8 p.m. to 9 p.m. when people head toward their big screen TVs and home computers. 'It is [not] so much a peak as it is a plateau,' says Andrew Tang, senior director of the smart energy web at Pacific Gas & Electric. '8 p.m. is kind of a recent phenomenon.' Providing power during the peak hours is already a costly proposition because approximately 10 percent of the existing generating capacity only gets used about 50 hours a year: Most of the time, that expensive capital equipment sits idle waiting for a crisis. Efforts to reduce demand are already underway with TV manufacturers working to reduce the power consumption in LCD and plasma while Intel and PC manufacturers are cranking down computer power consumption. 'Without a doubt, there's demand' for green PCs, says Rick Chernick, CEO of HP partner Connecting Point, adding that the need to be green is especially noticeable among medical industry enterprise customers."

Flavien writes "A team from the Security and Cryptography Laboratory (LASEC) in Lausanne, Switzerland, found 4 different ways to fully or partially recover keystrokes from wired keyboards at a distance up to 20 meters, even through walls. They tested 11 different wired keyboard models bought between 2001 and 2008 (PS/2, USB and laptop). They are all vulnerable to at least one of the 4 attacks. While more information on these attacks will be published soon, a short description with 2 videos is available."

tsm_sf writes "A recent Slashdot article got me thinking about dead and dying media. I'd like to build a cheap PC with the goal of being able to read as many old formats as possible. Size and power consumption would be design considerations; priority of media formats would be primary. How would you approach such a project?"

Heise.de's Kernel Log has a look at the ext4 filesystem as Linus Torvalds has integrated a large collection of patches for it into the kernel main branch. "This signals that with the next kernel version 2.6.28, the successor to ext3 will finally leave behind its 'hot' development phase." The article notes that ext4 developer Theodore Ts'o (tytso) is in favor of ultimately moving Linux to a modern, "next-generation" file system. His preferred choice is btrfs, and Heise notes an email Ts'o sent to the Linux Kernel Mailing List a week back positioning ext4 as a bridge to btrfs.

arcticstoat writes "It's sometimes easy to forget that the PC graphics market isn't owned by ATI and Nvidia, and the company that first gave us 3D acceleration, S3, is very much still around. So much so, in fact, that it's now even developed its own GPGPU technology. S3 claims that its Chrome 400 chips can accelerate gaming physics, HD video transcoding/encoding and photo enhancement. To demonstrate the latter, S3 has released a free download called S3FotoPro, which enhances color clarity and reduces haze in photos. However, the company hasn't yet revealed whether it plans to support OpenCL in the future." The Tech Report also points out that this could allow S3's parent company, VIA, to compete with Intel and AMD in graphics processing technology.

ThinSkin writes "Just when you thought laser and optical mice were enjoying their reign on mousepads worldwide, Microsoft has to come along and introduces their 'BlueTrack Technology,' a mouse tracking system that aims to work on virtually any terrain short of mirrored and reflective surfaces. ExtremeTech reviews the Explorer Mouse and Explorer Mini Mouse, both of which are powered by Microsoft's newest sensor, to see just how well this technology works. Testing on granite, carpet, marble, and other surfaces, the reviewers were impressed with the responsiveness of BlueTrack, but they also noted that laser mice were competitive on these surfaces as well. Even though the mice didn't get a recommendation from the reviewers (price being a major concern), they did admit that this BlueTrack is the best tracking system available today. MaximumPC has some pictures and a brief technical interview."

doomsdaywire writes "Buckypaper isn't exactly news to anyone here. However, this article quotes Ben Wang, director of Florida State's High-Performance Materials Institute, saying, 'Our plan is perhaps in the next 12 months we'll begin maybe to have some commercial products.' The article continues: '"If this thing goes into production, this very well could be a very, very game-changing or revolutionary technology to the aerospace business," said Les Kramer, chief technologist for Lockheed Martin Missiles and Fire Control, which is helping fund the Florida State research. ... The long-range goal is to build planes, automobiles and other things with buckypaper composites. The military also is looking at it for use in armor plating and stealth technology.'"
