Submission + - Frequency and use of Unix executables

Johnny Mnemonic writes: "I help Sys Admin a Linux setup. It has a several hundred end users, spread out in many locations and time zones. Our users often write their own bash/python/perl scripts to help with their daily duties, and other users often invoke those scripts directly from the author's home directory when they have proven interesting and useful. Also, we have perhaps a dozen directories in which reviewed scripts can be located. Some of the scripts can be quite sophisticated, and grow to multiple hundreds of lines.

We have found that when a script is useful, our users expect it to work all of the time--regardless if the original author of the tool has quit, if the code breaks, or it doesn't scale up to being used by hundreds of users due to poor design. When that happens, we are put in the awkward and frustrating position of supporting a script that was poorly designed and/or poorly documented--and often the first time we are even made aware of it is via the trouble ticket for the tool breaking. So we are in mad scramble to understand the tool, and understand why it broke--and the users that have come to depend on it are breathing down our back.

The Sys Admin team would like to know all of the scripts that these users might be using. We care less about executables that have been written but aren't actually being used--so it's not really useful to just look for files which are +x. Our users are a clever bunch, and the utilities that they build themselves serve their needs well--we generally encourage this tool creation process. We encourage this kind of self-help, so we can't simply disable the ability to run arbitrary executables altogether. We just want to know about them when they build those tools, so we can better support them should they become popular with other users and useful to the business.

How are you aware of all of the scripts and tools that your users build for each other? How and when do you accept support responsibilities for home grown tools? How do you require users who just want to get the job done to accept coding conventions and best-practices? We have tried to mandate that the user base accept these from the outset of their development--but have found that strictly enforcing good code hygiene from the outset actually results in them talking to us less, not more--and makes the problem worse, not better.

Thanks!"

Submission + - Star Wars Tech: True Green Laser Developed.

dusty writes: "Remember those green lasers from Star Wars? Turns out that faking green lasers has been easy for years , but making true green laser diodes has been the stuff of science fiction. Until recently that is. Now researchers from Japan have created the world's first true green laser diode. Until now only red and blue laser diodes were available and now with the addition of green new TV's and projectors that are more efficient can be produced. And if you were wondering how green lasers pointers are already produced, it is a hack that involved doubling the frequency of an infrared laser. The new true green laser diodes have much higher efficiency than the current 6% leading many to expect big time laser display breakthroughs in the near future. Ars Technica has a well written article on this breakthrough, and although the current lasers are no where near the power of the Death Star or Luke's lightsaber, seems anything can happen given enough research and time."

Submission + - Sandia Studies Botnets in 1M OS Digital Petri Dish

Ponca City, We love you writes: "The NY Times reports that researchers at Sandia National Laboratories are creating what is in effect a vast digital petri dish able to hold one million operating systems at once in an effort to study the behavior of botnets. To stalk the botnets, Sandia Scientist Ron Minnich, the inventor of LinuxBIOS who specializes in computer security and his colleague Don Rudish have converted a Dell supercomputer to simulate a mini-Internet of one million computers. The researchers say they hope to be able to infect their digital petri dish with a botnet and then gather data on how the system behaves. "When a forest is on fire you can fly over it, but with a cyberattack you have no clear idea of what it looks like," says Minnich. "It's an extremely difficult task to get a global picture." The Dell Thunderbird supercomputer, named MegaTux, has 4,480 Intel microprocessors running virtual machines with Wine, making it possible to run 1 million copies of Windows without paying licensing fees to Microsoft. MegaTux, a reference to Tux, the penguin character that is the official mascot of the Linux operating system, is an example of a new kind of computational science, in which computers are used to simulate scientific instruments that were once used in physical world laboratories. "One of the advantages of such a system is that we can stop the simulation at any point and look for patterns," says Rudish. "It's one of the neat things you can do when you crash a simulation of a 747 on a supercomputer.""

An anonymous reader writes: The Obama administration has released more than a thousand intelligence images of Arctic ice, following a declassification request by the National Academy of Sciences. These high-resolution spy photos of rapid sea ice loss off the northern coast of Alaska, kept classified by the Bush administration, show the devastating impact of global warming in the Arctic. The newly-declassified images also reveal the retreat of glaciers in Washington and Alaska.

Submission + - Will 'Cloud Brokers' Be the Key to Cloud Adoption? (datacenterknowledge.com) 1

miller60 writes: "Confused by all the cloud computing hype? So are many end users who could benefit from cloud platforms. The beneficiaries of this confusion could be "cloud brokers", middlemen who help enterprises choose the right platform and deploy apps across multiple clouds, and may eventually provide cloud arbitrage services that allow users to jump between platforms to capture the best pricing. Will the winners in this space be new players like CloudKick and RightScale or established system integrators like CSC? A key battleground may be federal agencies, where Amazon Web Services Federal is already offering training for IT service providers with government ties."

Submission + - Pitching Robot Hits Strike Zone 90% of Time

Hugh Pickens writes: "ESPN reports that University of Tokyo professor Masatoshi Ishikawa has created a pitching robot that can throw 90 percent of its pitches in the strike zone, won't need any relief from the bullpen and never asks for a pay raise. The pitching robot throws a plastic foam ball at 25 miles per hour, but Ishikawa is hoping to increase the speed to 93 mph and make it able to throw off-speed pitches like curves and sliders. Ishikawa has also created a batting robot, which has a sensor to determine if pitches are strikes or balls, hits balls in the strike zone almost 100 percent of the time, doesn't swing at pitches outside the strike zone, and is guaranteed to pass all drug tests. In a demonstration designed to showcase the speed at which multiple high-speed industrial robots can respond to external circumstances and perform activities together — the researchers placed the robot pitcher 3.5 meters away from the mechanical batter. The pitching robot's throws posed little challenge to the batter, whose 1000-frame-per-second camera eyes allow it to see the ball in super slow motion as it approaches. "The demand level of the robotics technology of each robot is very high," Ishikawa says. "What was difficult was to create a mechanism to satisfy such a high level of demand.""

The sequel to Tron, the classic movie from 1982 dealing with videogames, virtual reality and 3D graphics when none of these three things was widely popular, has got an official title and synopsis now while the major has released (and this time without silly censorship) the very first trailer from the movie together with some concept art and the teaser poster."

Submission + - Stallman Says Pirate Party Hurts Free Software (gnu.org)

bonch writes: Richard Stallman has written an article on the GNU website describing the effect the Swedish Pirate Party's platform would have on the free software movement. While he supports general changes to copyright law, he makes a point that many anti-copyright proponents don't realize--the GPL itself is a copyright license that relies on copyright law to protect access to source code. According to Stallman, the Pirate Party's proposal of a five-year limit on copyright would remove the freedom users have to gain access to source code by eventually allowing its inclusion in proprietary products. Stallman suggests requiring proprietary software to also release its code within five years to even the balance of power.

Submission + - A Closer Look At Safari 4: Browser Speed Wars (hothardware.com)

MojoKid writes: "In early June, Apple released what is arguably its most significant upgrade to Safari yet: Safari 4. In typical Apple fashion, the company was quick to deem it the "world's fastest and most innovative browser." This performance review and showcase sets out to find if that bold claim is indeed true. Breaking down the features and performance profile of Safari 4--along with its fiercest competitors--on both the Mac and PC side, it's clear to see that Apple's web browser has come a long way and in many cases is indeed one of the fastest, though the most innovative claim is likely debatable. That said, the web browser wars are heating up and all told, it's very good for the consumer in the end."

Submission + - 'Vanish' Makes Sensitive Data Self-Destruct

Hugh Pickens writes: "The NY Times reports on new software called "Vanish" developed by computer scientists at the University of Washington that makes sensitive electronic messages "self destruct" after a certain period of time. The researchers say they have struck upon a unique approach that relies on "shattering" an encryption key that is held by neither party in an e-mail exchange but is widely scattered across a peer-to-peer file sharing system. "Our goal was really to come up with a system where, through a property of nature, the message, or the data, disappears," says Amit Levy who helped create Vanish, released as a free, open-source tool that works with the Firefox browser. To work, both the sender and the recipient must have installed the tool. The sender then highlights any sensitive text entered into the browser and presses the "Vanish" button. The tool encrypts the information with a key unknown even to the sender. That text can be read, for a limited time only, when the recipient highlights the text and presses the "Vanish" button to unscramble it. After eight hours the message will be impossible to unscramble and will remain gibberish forever. Tadayoshi Kohno says Vanish makes it possible to control the "lifetime" of any type of data stored in the cloud, including information on Facebook, Google documents or blogs. "Today many people pick up the phone when they want to talk with a lawyer or have a private conversation," Kohno said. "But more and more communication is happening online. Vanish is designed to give people the same privacy for e-mail and the Web that they expect for a phone conversation.""

Submission + - Unusual physics engine game ported to Linux (blogspot.com)

christian.einfeldt writes: "Halloween has come early for Linux-loving gamers in the form of the scary Penumbra game trilogy, which has just recently been ported natively to GNU-Linux by the manufacturer, Frictional Games. The Penumbra games, named Overture, Black Plague, and Requiem, respectively, are first person survival horror and physics puzzle games which challenge the player to survive in a mine in Greenland which has been taken over by a monstrous infection/demon/cthulhu-esque thing. The graphics, sounds, and plot are all admirable in a scary sort of way. The protagonist is an ordinary human with no particular powers at all, who fumbles around in the dark mine fighting zombified dogs or fleeing from infected humans. But the game is remarkable for its physics engine — rather than just bump and acquire, the player must use the mouse to physically turn knobs and open doors; and the player can grab and throw pretty much anything in the environment. The physics engine drives objects to fly and fall exactly as one would expect. The porting of a game with such a deft physics engine natively to Linux might be one of the most noteworthy events for GNU-Linux gamers since the 'World of Goo' Linux port."

Submission + - The Pirate Bay R.I.P. (betanews.com)

CrashNBrn writes: We have heard rumblings of The Pirate Bay going the way of the DoDo Bird. The possibility that the current owners were considering selling. This has indeed occurred.
According to BetaNews, "Wayne Rosso, former president of Grokster has been working with Global Gaming Factory X, the Swedish firm that recently bought the Pirate Bay, to turn the service legit and legal without changing the user experience at all."
Rosso said, "I'm calling this new model 'resource supported'. In short, the more computer resources the user contributes to The Pirate Bay, the more his content consumption is subsidized. I won't drill down any further due to commercial confidentiality, but it can actually work. And if it does, it will be huge."

While the piratebay blog goes on to say, "If the new owners will screw around with the site, nobody will keep using it. That's the biggest insurance one can have that the site will be run in the way that we all want to. And — you can now not only share files but shares with people. Everybody can indeed be the owner of The Pirate Bay now. That's awesome and will take the heat of us."

Color me skeptical, but it should certainly be interesting seeing the fallout from this.
