Submission + - Does IPv6 Actually Work? (

darthcamaro writes: We've all been hearing for years that we should start looking at IPv6 — and now that IPv4 that seems really obvious, but there is a catch..IPv6 isn't quite ready to be deployed at scale. There are a long list of interoperability issues including problems with DHCPv6, IPv4 to IPv6 transition system mechanisms and oh yeah, web applications too.

"There are still known issues with DNS records, and if you have a AAAA record and an A record, what happens to your application?" Winters said. "You go to the AAAA and if it's not there, your application will hang." AAAA is the IPv6 record type in DNS, while the A record is for IPv4. Winters noted that it is surprising how some applications will only take the top record from a DNS resolver, whatever that record may be. He added that there is an IETF draft called, Happy Eyeballs which attempts to help resolve that issue.


Willow Garage Robot Fetches Beer, Engineers Rejoice 114

kkleiner writes "Willow Garage has pulled off the ultimate engineering feat: teaching a PR2 robot to fetch you a beer from the fridge. Not only can the PR2 select the correct brew from the fridge, it can deliver, and even open the beer as needed. That's right, all the humans have to do is drink and relax. Prepare yourself for some major robot-envy as you check out the PR2 delivering much-needed refreshment in the video."

Submission + - Avatar could have been so much more (

bowman9991 writes: Avatar’s story is predictable and clichéd, its characters 2 dimensional, yet it still manages to be a visual masterpiece. Futuristic visual display panels, beautifully constructed spacecraft, and high tech military air and land machines are all believable and captivating on multiple levels. Floating mountains, tangled forests and evocative landscapes are beautifully rendered. However, Avatar’s main characters are cardboard cut-outs, it's story predictable and clichéd. The dialogue never rises above the level of a computer game or TV show. "My goal is to rekindle those amazing mystical moments my generation felt when we first saw '2001: A Space Odyssey,' or the next generation's 'Star Wars.', Cameron originally revealed when promoting the film. Unfortunately though, he has failed. Compared to a film like 2001, Avatar is seriously lacking. Stanley Kubrick’s film had ground breaking special effects sequences (for its time), but unlike Avatar it also had a plot layered with new ideas, mystery and intrigue. What exactly is the monolith first found on the moon? Why did Hal, the shipboard artificial intelligence, lose its mind and start killing crewmembers? Some of 2001’s dialogue was decidedly average like Avatar, but at times it was fantastic (“Dave, my mind is going. I can feel it. I can feel it. My mind is going. There is no question about it. I can feel it. I can feel it. I can feel it. I'm a... fraid.”) and there were so many wonderful moments and intrigue 2001 has been a subject of discussion for decades. Perhaps Cameron should have kept the directors chair but left the writing to someone else.

Submission + - Surgery Museum Makes You Grateful for Any Modern H (

Xerfas writes: Granddads would have you believe things were better in the good ol' days, but a short stroll through the International Museum of Surgical Science in Chicago makes liars of them all.

From graphic paintings of childbirth to a vast collection of often-ghastly tools of the trade, the Surgical Museum is a morbidly fascinating journey into the blood-spattered beginnings of modern medicine. After a look at these hair-raising exhibits, you might remark that while the United States may be in serious need of health care reform, at least we have anesthetics and the germ theory of disease.

Read on for a photo tour of the museum that will make you grateful you weren't sick back when surgeons wielded tools that would make Sweeney Todd blush.

SlappingOysters writes: "The differences in PS3 and Xbox 360 hardware capabilities have been debated since the dawn of next-gen, but has the Xbox 360 finally revealed its Achilles heel? John Carmack of id Software states that the PS3 version of the upcoming cross-platform first person shooter RAGE will look better than the Xbox 360 version of the game. This gameplayer article examines whether John Carmack's words are the beginning of the end in the next-gen hardware wars?"

Submission + - SpaceX Receives USAF Operational License (

FiggyOO writes: "For those of you who witnessed the launch of SpaceX's Falcon 1 rocket, launch 3, you will be glad to hear that SpaceX has received a license to launch from space complex 40 (SLC-40) at Cape Canaveral Air Force Station on the Florida coast. This Launch complex is just south of launch pads 39A and 39B which have been used to launch the space shuttles, and will continue to for a few more years. This launch complex will enable them to launch the much anticipated Falcon 9 rocket which will eventually carry the Dragon capsule. In doing so, SpaceX hopes to fill the void between the end of the shuttle program, and the constellation program.
They have already begun moving into the launch complex, including moving a 125,000 gallon liquid oxygen tank on the back of a semi."

Journal Journal: Joining The Navy After High School - A Slashdotter's View

As many of the folks on my friends list know, I'm an active duty member of the United States Navy. Prior to enlistment, I spent a few years as a general I.T. nerd, doing software development (desktop and web applications, mostly on Linux) and network security work. At age 25, I made the decision to enlist in the Navy, and have been extremely happy with my decision ever since.

Submission + - Managing Large Windows Workgroup With *Nix

Dizzaster writes: I've just started in IT for a software development company that has roughly 100 XP boxes running as a single workgroup. They have various linux and unix boxes running basic network services (dns, apache, samba) in the backend and I've been tasked with both performing a full network and systems audit as well as figuring out a way to centrally manage the network when the audit is complete. In a mixed windows-unix environment that has no central authentication, no management infrastructure whatsoever, and with a zero tolerance policy for anyone even considering a windows domain, can anyone on /. provide suggestions for a unix based windows workgroup administration tool and a way to audit hardware and software on a large xp workgroup without manually going to each and every computer?

Submission + - Rosetta Disk Designed for 2,000 Years Archive

Hugh Pickens writes: "Kevin Kelly has an interesting post about an archive designed with an estimated lifespan of 2,000 -10,000 years to serve future generations as a modern Rosetta Stone. The Rosetta disk contains analog "human-readable" scans of scripts, text, and diagrams using nickel deposited on an etched silicon disk and includes 15,000 microetched pages of language documentation in 1,500 different language versions of Genesis 1-3, a universal list of the words common for each language, and pronunciation guides. Produced by the Long Now Foundation, the plan is to replicate the disk promiscuously and distribute them around the world in nondescript locations so at least one will survive their 2,000-year lifespan. "This is one of the most fascinating objects on earth," says Oliver Wilke. "If we found one of these things 2,000 years ago, with all the languages of the time, it would be among our most priceless artifacts. I feel a high responsibility for preserving it for future generations.""

Submission + - Home science under attack (

burnunit writes: Best described by Robert Bruce Thompson in his post "home science under attack" ( :

The Worcester Telegram & Gazette reports that Victor Deeb, a retired chemist who lives in Marlboro, has finally been allowed to return to his Fremont Street home, after Massachusetts authorities spent three days ransacking his basement lab and making off with its contents.
Deeb is not accused of making methamphetamine or other illegal drugs. He's not accused of aiding terrorists, synthesizing explosives, nor even of making illegal fireworks. Deeb fell afoul of the Massachusetts authorities for ... doing experiments.

Authorities concede that the chemicals found in Deeb's basement lab were no more hazardous than typical household cleaning products. Despite that, authorities confiscated "all potentially hazardous chemicals" (which is to say the chemicals in Deeb's lab) from his home, and called in a hazardous waste cleanup company to test the chemicals and clean up the lab.

Pamela Wilderman, the code enforcement officer for Marlboro, stated, "I think Mr. Deeb has crossed a line somewhere. This is not what we would consider to be a customary home occupation."

Allow me to translate Ms. Wilderman's words into plain English: "Mr. Deeb hasn't actually violated any law or regulation that I can find, but I don't like what he's doing because I'm ignorant and irrationally afraid of chemicals, so I'll abuse my power to steal his property and shut him down."

In effect, the Massachusetts authorities have invaded Deeb's lab, apparently without a warrant, and stolen his property. Deeb, presumably under at least the implied threat of further action, has not objected to the warrantless search and the confiscation of his property. Or perhaps he's just biding his time. It appears that Deeb has grounds for a nice juicy lawsuit here.

There's a lesson here for all of us who do science at home, whether we're home schoolers or DIY science enthusiasts. The government is not our friend. Massachusetts is the prototypical nanny state, of course, but the other 49 aren't far behind. Any of us could one day find the police at the door, demanding to search our home labs. If that day comes, I will demand a warrant and waste no time getting my attorney on the phone.

There's a word for what just happened in Massachusetts. Tyranny. And it's something none of us should tolerate.


Submission + - Vista's Security Rendered Completely Useless (

scribbles89 writes: Vista's Security Rendered Completely Useless by New Exploit While this may seem like any standard security hole, other researchers say that the work is a major breakthrough and there is very little that Microsoft can do to fix the problems. These attacks work differently than other security exploits, as they aren't based on any new Windows vulnerabilities, but instead take advantage of the way Microsoft chose to guard Vista's fundamental architecture. According to Dino Dai Zovi, a popular security researcher, "the genius of this is that it's completely reusable. They have attacks that let them load chosen content to a chosen location with chosen permissions. That's completely game over."

Submission + - Vista memory protections rendered useless (

Trailrunner7 writes: Two security researchers have developed a new technique that essentially bypasses all of the memory protection safeguards in the Windows Vista operating system, an advance that many in the security community say will have far-reaching implications not only for Microsoft, but also on how the entire technology industry thinks about attacks. In a presentation at the Black Hat briefings, Mark Dowd of IBM Internet Security Systems (ISS) and Alexander Sotirov, of VMware Inc. will discuss the new methods they've found to get around Vista protections such as Address Space Layout Randomization(ASLR), Data Execution Prevention (DEP) and others by using Java, ActiveX controls and .NET objects to load arbitrary content into Web browsers.
