F5 Fires Back On Open Source SSL Accelerator 120

Posted by timothy from the first-name-basis dept.
Random Feature writes "In response to Build an Open Source SSL Accelerator, in which o3 magazine detailed how to build a solution comparable to an F5 BIG-IP 6900 on the cheap, F5 Fires Back claiming it's not as cheap as it appears and pointing out the potential performance implications of a 'cobbled together set of components designed to mimic similar functionality.' The discussion on the performance of the Open Source solution based on Opteron RSA operation processing capabilities brings into question the validity of the 'more SSL TPS for cheaper' argument presented by o3."

Creating a Low-Power Cloud With Netbook Chips 93

Posted by timothy from the but-what's-the-wattage-equivalent-cfl dept.
Al writes "Researchers from Carnegie Mellon University have created a remarkably low-power server architecture using netbook processors and flash memory cards. The server design, dubbed a 'fast array of wimpy nodes,' or FAWN, is only designed to perform simple tasks, but the CMU team say it could be perfect for large Web companies that have to retrieve large amounts of data from RAM. A set-up including 21 individual nodes draws a maximum of just 85 watts under real-world conditions. The researchers say that a FAWN cluster could offer a low-power replacement for sites that currently rely on Memcached to access data from RAM."

Encrypted But Searchable Online Storage? 266

Posted by timothy from the give-some-to-that-lawyer dept.
An anonymous reader asks "Is there a solution for online storage of encrypted data providing encrypted search and similar functions over the encrypted data? Is there an API/software/solution or even some online storage company providing this? I don't like Google understanding all my unencrypted data, but I like that Google can search them when they are unencrypted. So I would like to have both: the online storage provider does not understand my data, but he can still help me with searching in them, and doing other useful stuff. I mean: I send to the remote server encrypted data and later an encrypted query (the server cannot decipher them), and the server sends me back a chunk of my encrypted data stored there — the result of my encrypted query. Or I ask for the directory structure of my encrypted data (somehow stored in my data too — like in a tar archive), and the server sends it back, without knowing that this encrypted chunk is the directory structure. I googled for this and found some papers, however no software and no online service providing this yet." Can anyone point to an available implementation?

Lose Your Amazon Account and Your Kindle Dies 419

Posted by timothy from the just-give-us-the-money-and-nobody-gets-hurt dept.
Mike writes "If you buy a Kindle and some Kindle ebooks from Amazon, be careful of returning items. Amazon decided that one person had returned too many things, so they suspended his Amazon account, which meant that he could no longer buy any Kindle books, and any Kindle subscriptions he's paid for stop working. After some phone calls, Amazon granted him a one-time exception and reactivated his account again." Take this with as much salt as you'd like.

Why IT Won't Power Down PCs 576

Posted by timothy from the sheer-cussedness dept.
snydeq writes "Internal politics and poor leadership on sustainable IT strategies are among the top reasons preventing organizations from practicing proper PC power management — to the tune of $2.8 billion wasted per year powering unused PCs. According to a recent survey, 42 percent of IT shops do not manage PC energy consumption simply because no one in the organization has been made responsible for doing so — this despite greater awareness of IT power-saving myths, and PC power myths in particular. Worse, 22 percent of IT admins surveyed said that savings from PC power management 'flow to another department's budget.' In other words, resources spent by IT vs. the permanent energy crisis appear to result in little payback for IT."

Kyocera's OLED Phone Concept Charges As You Flex It 101

Posted by timothy from the other-products-to-flex-on-the-way dept.
Mike writes "Kyocera recently unveiled a kinetic energy-powered phone with a flexible OLED display that can be folded up like a wallet. Dubbed the EOS phone, the display unfolds to reveal a wide screen, and shape memory allows the phone's keys to pop up when in use and blend in with the surface during downtime. Best of all, the phone's soft, semi-rigid polymer skin is embedded with an array of tiny piezoelectric generators — the more you use the phone, the more it charges!" So far, it's just a design idea — but a cool one.

Cinder Mobile OS Lets Users Send More Power To Slow Apps 92

Posted by timothy from the would-like-something-like-that-in-my-laptop dept.
alphadogg writes with this excerpt from Network World: "Stanford University researchers are designing an operating system from the ground up to handle the power and security requirements of mobile devices. The Cinder operating system is already working on an Arm chip, and members of the team are working on making it run on the HTC G1 handset, according to Philip Levis, a Stanford assistant professor. Levis spoke about Cinder at the Stanford Computer Forum on Tuesday. If an application isn't running as fast as the user wants, a Cinder-based phone could include a button to boost the energy allocated to that application, Levis said. Cinder also could allow users to download any code and run it safely on their phones in a 'sandbox' mode."

Visualizing Data Inside the 30-ft Allosphere 131

Posted by timothy from the bah-I've-seen-bigger dept.
TEDChris writes "The Allosphere, being created at UC Santa Barbara, is the most ambitious attempt yet at creating powerful 3d visualizations of raw scientific data, such as the structure of a crystal, or how quantum effects take place. Researchers watch from a bridge inside the 30-foot sphere, looking at data projected 360 degrees around them and listening to 3D sound. The first major public demo of the facility has just been posted at TED.com. Optimists would argue that many of the greatest scientific breakthroughs happened through a new visual way of imagining data. Penicillin and relativity come to mind. So this is either a killer new research vehicle, an incredible toy, or just an insanely expensive art project."

An article over at o3magazine.com shows you how to build an SSL accelerator that's on par with the commercial solutions, using Open Source projects. SSL Accelerators offload the encryption / decryption process from web servers, reducing load and reducing the number of certificates needed."

Energy Secretary Chu Endorses "Clean Coal" 464

Posted by timothy from the was-then-is-now dept.
DesScorp writes "The Wall Street Journal is reporting that Energy Secretary Steven Chu is endorsing 'clean coal' technology and research, and is taking a pragmatic approach to coal as an energy supply. '"It absolutely is worthwhile to invest in carbon capture and storage because we are not in a vacuum," Mr. Chu told reporters Tuesday following an appearance at an Energy Information Administration conference. "Even if the United States or Europe turns its back on coal, India and China will not," he said. Mr. Chu added that "quite frankly I doubt if the United States will turn its back on coal. We are generating over 50% of our electrical energy from coal."' The United States has the world's largest reserves of coal. Secretary Chu has reversed his positions on coal and nuclear power, previously opposing them, and once calling coal 'My worst nightmare.'"

Online Storage For Lawyers? 287

Posted by timothy from the due-diligence-best-practices dept.
alharaka writes "I have a relative that has been a lawyer for over two decades. In passing conversation, he revealed to me that he has a great deal of his data stored on floppies. Naturally, as an IT guy, I lost it on him, telling him that a one-dimensional storage strategy of floppies was unacceptable. If he lost those files, his clients would be enraged. Since I do not know much about online data storage for lawyers, I read a few articles I found on Google. A lot of people appear to recommend CoreVault, since a few bar associations, including Oklahoma, officially endorsed them. That is not enough for me. Do any Slashdotters have info on this topic? Do you have any companies you would recommend for online data storage specifically for lawyers? My relative is a lawyer with recognition in NJ, NY, CA, and DC; are there any rules and regulations you know of regarding such online storage he must comply with? I know IT and not law. I am aware this is not a forum for legal advice, but do any IT professionals who work for law firms know about such rules and regulations?"

Work Progresses On 10,000 Year Clock 307

Posted by timothy from the artifexian-contrapulation dept.
KindMind writes "CNet has pictures of a planned 10,000 year clock to be built in eastern Nevada by the Long Now Foundation. From the article: 'Running under its own power, the clock is an experiment in art, science, and engineering. The six dials on the face of this machine will represent the year, century, horizons, sun position, lunar phase, and the stars of the night sky over a 10,000-year period. Likely to span multiple generations and evolutions in culture, the thinking and design put into the monument makes it a moving sculpture as beautiful as it is complex.' This was reviewed on Slashdot in 2005. Really cool pictures, including one of a mechanical 'binary computer' that converts the pendulum into positions on the dial."

Xinhua news agency quoted Chinese foreign ministry spokesperson Jiang Yu as saying that any sort of involvement from China in the incident 'doesn't exist at all.' The denial follows a report in the Wall Street Journal which claimed that agents from China and Russia along with several other countries had infiltrated the computer systems charged with managing electricity in the US and left behind software payloads which could be used to control or disable electric grids in the US." Bruce Schneier is skeptical about the whole story.

N!NJA writes "California's biggest energy utility announced a deal Monday to purchase 200 megawatts of electricity from a startup company that plans to beam the power down to Earth from outer space, beginning in 2016. Solaren would generate the power using solar panels in Earth orbit and convert it to radio-frequency transmissions that would be beamed down to a receiving station in Fresno, PG&E said. From there, the energy would be converted into electricity and fed into PG&E's power grid."

Intel Responds To X25-M Fragmentation Issue 111

Posted by Soulskill from the problem-what-problem dept.
Vigile writes "In mid-February, news broke about a potential issue with Intel's X25-M mainstream solid state drives involving fragmentation and performance slow-downs. At that time, after having the news picked up by everyone from CNet to the Wall Street Journal, Intel stated that it had not seen any of these issues but was working with the source to replicate the problem and find a fix if at all possible. Today Intel has essentially admitted to the problem by releasing a new firmware for the X25-M line that not only fixes the flaws found in the drive initially, but also increases write performance across the board."

iPhone Jailbreaking Still Going Strong 166

Posted by samzenpus from the don't-touch-the-apples dept.
snydeq writes "Despite the productivity promises of Apple's forthcoming 3.0 firmware update, jailbreaking should continue to push the iPhone's productivity envelope, as users increasingly demand the Holy Grail of smartphone power use: applications that run in the background, InfoWorld reports. Copy and paste, video recording and streaming, Internet tethering, and content search are just a few of the features over which iPhone users have sought to jailbreak their devices — a practice Apple itself has done little to crack down on. Jailbreak apps circumvent hardware and software restrictions that Apple says ensure a consistent, responsive user interface and optimal battery endurance. In particular, jailbroken phones can run apps in the background, a capability Apple reserves for its own apps but prohibits in third-party programs. Jay Freeman, creator of the Cydia iPhone installer and Cydia Store, however, believes a free-market approach is the best way to satisfy power users' demands for features without compromising the performance of their iPhones. And given Apple's App Store overcrowding, it seems likely that jailbroken phones and app venues like Cydia Store will continue to be popular with iPhone customers and developers, even after the 3.0 firmware ships."

Flying Micro-Robot Takes Off 72

Posted by samzenpus from the fly-on-the-wall dept.
AndreV writes "A University of Waterloo in Ontario engineering research team has developed the world's first flying micro-robot capable of manipulating objects for micro-scale applications, which include micro-assembly of mechanical components, handling of biological samples and even microsurgery. It moves around and manipulates objects with micro-grippers, remotely controlled by a laser-focusing beam (heating the pincers with a laser opens them; when the laser is turned off, they cool and close). Its magnetic drive mechanism controls the field using continuous feedback from positioning sensors in order to position the 'bot. 'It can enter virtually any space and can be operated in a sealed enclosure by a person outside,' the project leaders says, 'which makes it useful for handling bio-hazardous materials or working in vacuum chambers and clean rooms.' The video of the contraption shows it floating in mid-air."
