Submission + - High Performance Linux Firewalling 1

Submitted by LinuxOps on Wednesday October 24, 2007 @06:16AM

LinuxOps writes: I have an opportunity to introduce Linux to a large client which is currently a 100% MS shop. They are upgrading their internet link to a whopping 10Gb (yes, _ten_gigabit_ to the internet) and are looking for a high performance firewall solution. They know it's going to be a major task but projected bandwidth requirement to support their multiple worldwide sites means any slower link is not enough. Obviously it needs firewalled but the firewall needs to be fast enough not to become the bottleneck and, effectively, reduce the link throughput to unacceptable levels. I've built firewalls on links up to 1Gb but this is an order of magnitude greater and I wanted to throw it open to the /. crowd to make suggestions for how I could use this as an opportunity to show Linux performing ahead of all the other options. This 100% MS shop is looking to how this performs to make OS decisions for their future strategy, so there is a lot riding on this. What recommendations do you have to get a 10Gb firewall running at maximum throughput on Linux ? Hardware, Intel/AMD, distro etc. ? What about making it HA ?

Submission + - Robotics goes open source (zdnet.com)

Submitted by azuredrake on Wednesday October 24, 2007 @04:49AM

azuredrake writes: ZDNet reports on a Silicon Valley company named Willow Garage which is attempting to foster an open-source community to advance the field of robotics. Among other projects, the company is working on an autonomous, solar-powered boat for ocean research, and a car capable of driving itself through traffic situations and self-parking. The novel aspect to this company, however, is that it's a privately owned company which seems more interested in advancing its field of study than in turning a quick profit. Whether or not this proves a viable business model remains to be seen, but they seem to have the potential to revolutionize the field of personal robotics.

Submission + - Aussie Claims Copper Broadband now 200x Faster (beskerming.com)

SkiifGeek writes: "Winner of Melbourne University's Chancellor's Prize for Excellence, Dr John Papandriopoulos could soon find himself the focus of a number of networking companies and government agencies interested in wringing more performance from existing network infrastructure.

Dr John developed a set of algorithms (US and Aussie patents pending) that reduce the impact of cross talk on data streams sharing the same physical copper line, taking less than a year to achieve the breakthrough. It is claimed that the algorithms can produce up to 200x improvement over existing copper broadband performance (quoted as being between one and 25 mbit/sec), with up to 200 mbit/sec apparently being deliverable. If the mathematical theories are within even an order of magnitude of the actual gains achieved, Dr John's work is likely to have widespread implications for future bandwidth availability across the globe."

Roland Piquepaille writes: "Researchers at Clarkson University, NY, have developed wireless bridge sensors which work without batteries. Instead, they are powered by the vibrations caused by passing traffic. This is good news for all the people in charge of maintaining bridges, who will no longer to have to replace batteries installed in hard-to-access locations. As said one of the researchers, 'We have completely eliminated the battery from the equation. Hermetically sealed wireless sensors powered by bridge vibration can remain on the bridge without need of maintenance for decades, providing continuous monitoring of such parameters as ice conditions, traffic flows and health status.' Nice job, but read more for additional details and a picture of a wireless bridge sensor used to check the safety of the Route 11 bridge in Potsdam, N.Y."

Submission + - LoggerFS: a revolutionary take on logging (itauth.com)

Submitted by Anonymous Coward on Monday October 22, 2007 @10:14PM

An anonymous reader writes: LoggerFS is a FUSE-based virtual file system written in C++ using the FUSEXX C++ bindings. It seamlessly passes log data through the file system and directly into a database. Unlike existing log parsers, which often run periodically and scan the entire file for changes, LoggerFS takes a unique approach by masking the database backend with a filesystem frontend. When log lines are appended to a virtual file on the LoggerFS file system, lines that match a regex pattern are directly stored in a database. Read on for an Introduction to LoggerFS.

Submission + - Use a surge protector, Void your PS3 Warranty

Submitted by Direwolf20 on Monday October 15, 2007 @04:50PM

Direwolf20 writes: A friend of mine called Sony Customer Support when his 4 month old Playstation 3 bricked one night (while sitting idle). Customer support tried to tell him that it probably got hit by an electrical surge. When he told the CSR that the PS3 was connected to a surge protector, the CSR informed him that connecting his PS3 to a surge protector voids the warranty, and therefore he'll have to shell out $150 to get it fixed.

Submission + - Yahoo "Next" has been hacked 1

vindimy writes: "Yahoo Next" at http://next.yahoo.com/, which serves the same purpose as Google Labs to Google, has been defaced by an unknown individual or team. Looking at the screenshot, it seems that they didn't have any evil in mind and it's just a humorous prank. We're left wondering how it will affect people's perception of what's really coming up next on Yahoo.

achillean writes: Is BSD ready for prime-time? PC-BSD 1.4, a desktop-centered, FreeBSD based operating system has just been released and is looking to attract attention from the growing throngs of Linux users. But how well does it stack up to popular and easy to use Linux distributions like Ubuntu? Why should anyone care about BSD, isn't it dead? Read on for more about the latest release of this up-and-coming desktop BSD, including installation and desktop screenshots.

Rick Zeman writes: "This tongue-in-cheek article says, 'It seems as if every commercial these days has a rock band in it. What was once the mark of utter uncoolness, a veritable byword of selling out, has become the norm. More than a decade ago we became inured to the most unlikely parings. Led Zeppelin in a Cadillac ad. The Clash shilling for Jaguar. Bob Dylan warbling for an accounting firm, or Victoria's Secret. An Iggy Pop song about a heroin-soaked demimonde accompanying scenes of blissful vacationers on a Caribbean cruise ship.....' Fret no more as to who's a bigger sellout as The Moby Equation has been conceived. The Moby equation '...determines the degree to which artists besmirch their reputations when they lend their music to hawk products or companies. (The name salutes the techno artist Moby, who took the practice to new extremes with his 1999 album "Play.") The Moby Equation seeks to quantify just who is the bigger sellout out based on many variables, from 'sacredness of the song' to 'time since artist's heyday.' There's even a calculator to calculate your own sell-out!"

An anonymous reader writes: The Dojo Toolkit's 0.9 release has come with a lot of small changes, most notably to their underlying asynchronous function calls. Where everything used to go through the dojo.io.bind command, they've separated the functionality into different methods now: xhrGet, xhrPost, xhrPut and xhrDelete. Following is an introduction to the former two methods: xhrGet and xhrPost. Learn how to asynchronously submit forms and transparently send content back and forth between the client and the server using both GET and POST.
