Windows 7 Hard Drive and SSD Performance Analyzed 248

bigwophh writes "Despite the fact that Windows 7 is based on many of the same core elements as Vista, Microsoft claims it is a different sort of animal and that it should be looked at in a fresh, new light, especially in terms of performance. With that in mind, this article looks at how various types of disks perform under Windows 7, both the traditional platter-based variety and newer solid state disks. Disk performance between Vista and Win7 is compared using a hard drive and an SSD. SSD performance with and without TRIM enabled is tested. Application performance is also tested on a variety of drives. Looking at the performance data, it seems MS has succeeded in improving Windows 7 disk performance, particularly with regard to solid state drives."

Allegedly Rigged Product Demo In SAP Suit Goes Missing 210

narramissic writes "Waste Management sued SAP in March 2008 over a failed ERP project. Now, well into the pre-trial discovery process, a presale product demonstration software package that Waste Management says was a key element of the 'false representations' SAP made to 'induce Waste Management into entering a software licensing and implementation agreement' has gone missing. Naturally, both sides say the other has it. And SAP, for its part, says it has 'searched extensively' for the system and wants it 'as much or more' as Waste Management, since it 'will help SAP disprove WM's fraud claim.'"

45-Year-Old Modem Used To Surf the Web 622

EdIII writes with this awesome snippet from Hack a Day: "'[phreakmonkey] got his hands on a great piece of old tech. It's a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to see if it would actually work. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn't working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It's still amazing to see this machine working 45 years later.' Although impractical for surfing the Internet today, there is something truly cool about getting a 45-year old modem to work with modern technology. The question I have, is what is the oldest working piece of equipment fellow Slashdotters have out there? I'm afraid as far back as I can go is a Number Nine Imagine 128 Series 2 Graphics card on a server still in use at my house which only puts me at about 14 years."

Revived LHC Could Run Through the Winter 164

Jack Spine writes "When you are powering nuclear particle beams that could drill a hole through 30 metres of copper, you don't want to be paying a premium for electricity. However, Cern scientists are determined that the delayed experiment will get some workable results, and so are preparing to run the machine throughout the winter."

SATA 3.0 Release Paves the Way To 6Gb/sec Devices 248

An anonymous reader writes "The Serial ATA International Organization (SATA-IO) has just released the new Serial ATA Revision 3.0 specification. With the new 3.0 specification, the path has been paved to enable future devices to transfer up to 6Gb/sec as well as provide enhancements to support multimedia applications. Like other SATA specifications, the 3.0 specification is backward compatible with earlier SATA products and devices. This makes it easy for motherboard manufactures to go ahead and upgrade to the new specification without having to worry about its customers' legacy SATA devices. This should make adoption of the new specification fast, like previous adoptions of SATA 2.0 (or 3Gb/sec) technology."

A Widescreen Laser Projector In Your Pocket 189

Edis Krad writes "Redmond based company Microvision is in the last stages of developing and releasing a portable, laser-based projector, code-named 'Show WX.' The projector has a resolution of 848 by 400 pixels (WVGA) and, since it uses laser-scanning rather than LCD to form the images, it does not require a lens to focus, allowing it to display images virtually in any surface. The device comes with its own user-replaceable battery, which means you could take it with you anywhere you want. Although there is no pricing information on their website, according to this local news video, it could cost at least $200."

Painting The World's Roofs White Could Slow Climate Change 712

Hugh Pickens writes "Dr. Steven Chu, the Nobel prize-winning physicist appointed by President Obama as Energy Secretary, wants to paint the world white. Chu said at the opening of the St James's Palace Nobel Laureate Symposium that by lightening paved surfaces and roofs to the color of cement, it would be possible to cut carbon emissions by as much as taking all the world's cars off the roads for 11 years. Pale surfaces reflect up to 80 percent of the sunlight that falls on them, compared with about 20 percent for dark ones, which is why roofs and walls in hot countries are often whitewashed."

Using WiMAX To Replace a Phone? 169

vigmeister writes "I've decided to explore the possibility of using a netbook/MID as a phone while eschewing the services of a cellphone provider. Now that Atlanta (where I live) has WiMAX from Clear, I ought to be connected to the Internet everywhere within the city (once I sign up). Theoretically, this should mean that I will be able to use my netbook as a cell phone. Of course, there are some very real issues to overcome and I am simply putting this experiment together to see if it is something that is realistically possible. This could possibly extend to uncapped 3G connections (if they exist any more) as well. Are there any obvious problems you would foresee? Is there anything I have missed or any other questions I should attempt to answer in this 'experiment' of mine? A major issue is, of course, the fact that my pseudo-netbook has to be carried everywhere and always left on."

AT&T Says 7.2Mbps Wireless Coming This Year 141

CWmike writes "AT&T will upgrade to High Speed Packet Access (HSPA) 7.2 wireless networking technology later this year, offering faster (up to 7.2 Mbit/sec.) network speeds to new compatible laptop cards and smartphones due to be released at the same time, the company said today. Current HSPA download speeds can theoretically reach 3.6 MBit/sec, according to AT&T executives who commented on the planned upgrade in April. AT&T did not comment on which laptop cards and smartphones will be compatible with HSPA 7.2 other than to say it will introduce 'multiple' devices later this year. Could this be one of the big iPhone announcements to come from WWDC?"

Intel's Nehalem EX To Gain Error Correction 80

angry tapir writes "Intel's eight-core Nehalem EX server processor will include a technology derived from its high-end Itanium chips that helps to reduce data corruption and ensure reliable server performance. The processor will include an error correction feature called MCA Recovery, which will detect and fix errors that could otherwise cause systems to crash — it will be able to detect system errors originating in the CPU or system memory and work with the operating system to correct them." Update: 05/27 19:11 GMT by T : Dave Altavilla suggests also Hot Hardware's coverage of the new chip, which includes quite a bit more information.

Sony Rumored To Be Debuting Wiimote-Like Controller At E3 129

Anenome writes "Previously, we saw a Microsoft patent on a Wiimote-like device, and now rumors say that Sony too has a similar device in the works. This isn't surprising, given how dominant Nintendo's Wii has proved to be in this hardware generation. However, many gaming-geeks continue to lament the move away from plain old button-pressing. What is exciting is the prospect that all three companies may incorporate Johnny Lee-style head-tracking into the next console generation, which achieves a convincing 3D illusion on a regular vid-screen, leaving us just a few steps away from true positional 3D. Both the Microsoft and Sony patents incorporate a camera looking at the user, a required setup for achieving positional head-tracking."

Build an $800 Gaming PC 296

ThinSkin writes "Building a computer that can handle today's games doesn't have to cost an arm and a leg. In fact, you can build one for less than $800, especially given that many hardware manufacturers have cut costs considerably. Loyd Case over at ExtremeTech shows gamers how to build an $800 gaming PC, one that features an overclockable Intel Core 2 Quad Q8400 and a graphics-crunching EVGA 260 GTX Core 216. The computer exceeded expectations in gaming and synthetic tests, and was even overclocked well over spec at 3.01GHz."

Canonical Demos Early Stage Android-On-Ubuntu 165

An anonymous reader notes Ars Technica's report from the Ubuntu Developer Summit in Barcelona, where Canonical has unveiled a prototype Android execution environment that will allow Android applications to run on Ubuntu and "potentially other conventional Linux distributions." "Android uses the Linux kernel, but it isn't really a Linux platform. It offers its own totally unique environment that is built on Google's custom Java runtime. There is no glide path for porting conventional desktop Linux applications to Android. Similarly, Java applications that are written for Android can't run in regular Java virtual machine implementations or in standard Java ME environments. This makes Android a somewhat insular platform. Canonical is creating a specialized Android execution environment that could make it possible for Android applications to run on Ubuntu desktops in Xorg alongside regular Linux applications. The execution environment would function like a simulator, providing the infrastructure that is needed to make the applications run. Some technical details about the Android execution environment were presented by Canonical developer Michael Casadevall... They successfully compiled it against Ubuntu's libc instead of Android's custom libc and they are running it on a regular Ubuntu kernel."

Netbook-Run Dice Robot Can Rack Up 1.3 Million Rolls a Day 280

stevel writes "The owner of games site GamesByEmail.com created Dice-O-Matic, 'a machine that can belch a continuous river of dice down a spiraling ramp, then elevate, photograph, process and upload almost a million and a half rolls to the server a day. ... The Dice-O-Matic is 7 feet tall, 18 inches wide and 18 inches deep. It has an aluminum frame covered with Plexiglas panels. A 6x4 inch square Plexiglas tube runs vertically up the middle almost the entire height. Inside this tube a bucket elevator carries dice from a hopper at the bottom, past a camera, and tosses them onto a ramp at the top. The ramp spirals down between the tube and the outer walls. The camera and synchronizing disk are near the top, the computer, relay board, elevator motor and power supplies are at the bottom.' While not called out in the article, the pictures clearly show a Dell Mini 9 running the show (and performing the optical recognition of the dice values.) No, it's not running Linux."

Nanotech Memory Could Hold Data For 1 Billion Years 239

Hugh Pickens writes "Digital storage devices have become ubiquitous in our lives but the move to digital storage has raised concerns about the lifetime of the storage media. Now Alex Zettl and his group at the University of California, Berkeley report that they have developed an experimental memory device consisting of a crystalline iron nanoparticle enclosed in a multiwalled carbon nanotube that could have a storage capacity as high as 1 terabyte per square inch and temperature-stability in excess of one billion years. The nanoparticle can be moved through the nanotube by applying a low voltage, writing the device to a binary state represented by the position of the nanoparticle. The state of the device can then be subsequently read by a simple resistance measurement while reversing the nanoparticle's motion allows a memory 'bit' to be rewritten. This creates a programmable memory system that, like a silicon chip, can record digital information and play it back using conventional computer hardware storing data at a high density with a very long lifetime. Details of the process are available at the American Chemical Society for $30."

Robot Warfare Going Open Source 105

destinyland writes "Peter Singer, author of the new book Wired for War: The Robotics Revolution and Conflict in the 21st Century, says 'You can build your own version of the Raven drone, which is a widely used military drone, for about $1,000.' Singer argues that 'just like software, warfare is going open source.' He warns that, ultimately, robot warfare may even expand beyond the military using more DIY and off-the-shelf systems. In addition to 43 countries now working on military robots, there are 'non-state actors ranging from Hezbollah to this militia group in Arizona to a bunch of college kids at Swarthmore... One person's hobby — such as the hobbyist who flew a homemade drone from North America to Great Britain — can be another person's terrorist strike option.'"

The Great Ethanol Scam 894

theodp writes "Over at BusinessWeek, Ed Wallace is creating quite a stir, reporting that not only is ethanol proving to be a dud as a fuel substitute, but there is increasing evidence that it is destroying engines in large numbers. Before lobbyists convince the government to increase the allowable amount of ethanol in fuel to 15%, Wallace suggests it's time to look at ethanol's effect on smog, fuel efficiency, global warming emissions, and food prices. Wallace concedes there will be some winners if the government moves the ethanol mandate to 15% — auto mechanics, for whom he says it will be the dawn of a new golden age."

Where To Buy A Machine With Linux Pre-Installed 229

The Berkeley LUG has a neat aggregation of many different places where you can acquire a desktop, laptop, or even netbook with Linux pre-installed. The list starts with a link to Dell's Linux offering, includes many independent vendors, and many updates from user comments, almost all of whom seem to be drinking the Ubuntu kool-aid. "Over the last couple of years, Linux has come a long way in terms of hardware support, and these days it is relatively rare that an installation of ubuntu/fedora will be lacking any drivers for your machine. However, installing any OS can still sometimes be a tedious task and one that scares the wits out of the average computer user. And, for the expert users out there, it's just more fun to buy a computer with Linux already on it and not have to pay the Microsoft tax."
