The World's First Supercavitating Boat? 186

Posted by timothy
from the introducing-the-samsung-cavitate dept.
An anonymous reader writes "For decades, researchers have been trying to build boats, submarines, and torpedoes that make use of supercavitation — a bubble layer around the hull that drastically reduces friction and enables super-fast travel. Now a company in New Hampshire called Juliet Marine Systems has built and tested such a craft, and says it is the world's fastest underwater vehicle. The ship, called the 'Ghost,' looks like two supercavitating torpedoes with a command module on top, and can carry 18 people plus weapons and supplies. The company is in talks with the U.S. Navy to build a version of the ship that can guard the fleet against swarm attacks by small boats. The question is how well it really works, and whether it can be used reliably and effectively on the high seas."

Solving Climate Change By Bioengineering Humans? 363

Posted by Soulskill
from the just-lazy-enough-to-work dept.
derekmead writes "Forget CFLs, hybrid cars, and organic jeans. Buying our way out of climate change — even if it's green consumption — won't get us far. A new paper (PDF), published in Ethics, Policy, and the Environment by NYU bioethics professor S. Matthew Liao, poses an answer: engineer humans to use less. The general plan laid out by Liao is straightforward, ranging from using pharmacological behavior modification to create an aversion to meat in people, to using gene therapy to create smaller, less resource-intensive children. The philosophical and ethical questions, on the other hand, are absurdly complicated. The Atlantic also has a great interview with Liao, in which he talks about gene therapy and making humans hate the taste of meat."

Ask Slashdot: Tips On 2D To Stereo 3D Conversion? 125

Posted by timothy
from the aggghhh-my-eyes-my-eyes dept.
An anonymous reader writes "I'm interested in converting 2D video to Stereoscopic 3D video — the Red/Cyan Anaglyph type in particular (to ensure compatibility with cardboard Anaglyph glasses). Here's my questions: Which software(s) or algorithms can currently do this, and do it well? Also, are there any 3D TVs on the market that have a high quality 2D-to-3D realtime conversion function in them? And finally, if I were to try and roll my own 2D-to-3D conversion algorithm, where should I start? Which books, websites, blogs or papers should I look at?" I'd never even thought about this as a possibility; now I see there are some tutorials available; if you've done it, though, what sort of results did you get? And any tips for those using Linux?

PR Firm Unwisely Tangles With Penny Arcade 419

from the internet-lynch-mob-engaged dept.
New submitter FSWKU writes "Courtesy of Penny-Arcade, Paul Christoforo of Ocean Marketing provides a perfect example of what not to do when interacting with customers, especially if you are doing so on behalf of another company. There's name dropping, an ego trip worthy of Charlie Sheen, and even what appears to be a promise to commit libel. Other outlets are already picking up the story and running with it, and an examination of Ocean Marketing's website has generated accusations of plagiarism."

Ask Slashdot: Assembling a Linux Desktop Environment From Parts? 357

Posted by timothy
from the gnome-panel-and-thunar dept.
paxcoder writes "Gnome Shell ... is different. Very much so. The fallback was inadequate. I suspect that many people, like me, turned to the alternatives. My choice was LXDE, which worked ok, until (lx-)panel broke in the unstable branch of the distro that I use. Tired of using the terminal to run stuff, I replaced the standard panel with the one from Xfce. That made me realize that we really don't need a packaged desktop environment, there are pieces ready for assembly. If you customize your graphical environment, what elements do you use? Which window manager, file manager, panel(etc.) would you recommend? Do you have a panel with a hardware usage monitors, how do you switch between workspaces? Anything cool we might not know about?"

Yup. Give them an opportunity to make up the difference if you're more inclined to stay if the pay were right. If that doesnt work or if you'd rather leave anyway, give generous notice (I gave my last employer 4 weeks instead of the customary 2), and even offer to be available on a consultancy basis a few hours a week to help them through the transition. That'll also give you a bit of a further bonus in your pocketbook if they choose to do that.

Cloud-Powered Facial Recognition Is Terrifying 286

Posted by Soulskill
from the you-are-who-google-says-you-are dept.
oker sends this quote from The Atlantic: "With Carnegie Mellon's cloud-centric new mobile app, the process of matching a casual snapshot with a person's online identity takes less than a minute. Tools like PittPatt and other cloud-based facial recognition services rely on finding publicly available pictures of you online, whether it's a profile image for social networks like Facebook and Google Plus or from something more official from a company website or a college athletic portrait. In their most recent round of facial recognition studies, researchers at Carnegie Mellon were able to not only match unidentified profile photos from a dating website (where the vast majority of users operate pseudonymously) with positively identified Facebook photos, but also match pedestrians on a North American college campus with their online identities. ... '[C]onceptually, the goal of Experiment 3 was to show that it is possible to start from an anonymous face in the street, and end up with very sensitive information about that person, in a process of data "accretion." In the context of our experiment, it is this blending of online and offline data — made possible by the convergence of face recognition, social networks, data mining, and cloud computing — that we refer to as augmented reality.'

A Few Million Virtual Monkeys Randomly Recreate Shakespeare 312 Screenshot-sm

Posted by samzenpus
from the simpsons-did-it dept.
First time accepted submitter eljefe6a writes "On September 23 at 2:30 PST the A Million Amazonian Monkeys project successfully recreated A Lover's Complaint. This is the first time a work of Shakespeare has actually been randomly reproduced. It is one small step for a monkey, one giant leap for virtual primates everywhere. From the article: 'For this project, I used Hadoop, Amazon EC2, and Ubuntu Linux. Since I don’t have real monkeys, I have to create fake Amazonian Map Monkeys. The Map Monkeys create random data in ASCII between a and z. It uses Sean Luke’s Mersenne Twister to make sure I have fast, random, well behaved monkeys. Once the monkey’s output is mapped, it is passed to the reducer which runs the characters through a Bloom Field membership test. If the monkey output passes the membership test, the Shakespearean works are checked using a string comparison. If that passes, a genius monkey has written 9 characters of Shakespeare. The source material is all of Shakespeare’s works as taken from Project Gutenberg.'"

Fusion Garage Going After Lower-Price Tablet Market 196

Posted by Soulskill
from the wising-up dept.
nk497 writes "Fusion Garage has dropped the price of its follow-up to the JooJoo tablet, cutting the Grid10's price by $200 to $299 in the US and £259 in the UK. Outspoken CEO Chandrasekar Rathakrishnan has clearly been following the HP TouchPad fire sale, and noticed the importance of price when it comes to taking on Apple's iPad. He said there's no point in buying 'a poor carbon copy' of the Apple tablet for the same price. 'At $499, why would you buy — it's like going to China and buying a [fake] Louis Vuitton bag, at the same price as the real Louis Vuitton bags. It doesn't make sense, when you know it's a rip-off product,' he said."

Online Parody Cartoon Targeted For Prosecution 327

SeattleGameboy writes "It seems that the Renton (suburb of Seattle) police need a remedial course on the U.S. Constitution," linking to a story at Seattle TV station KIRO which says "The Renton City Prosecutor wants to send a cartoonist to jail for mocking the police department in a series of animated Internet videos. The 'South-Park'-style animations parody everything from officers having sex on duty to certain personnel getting promoted without necessary qualifications. While the city wants to criminalize the cartoons, First Amendment rights advocates say the move is an 'extreme abuse of power.'"

Honestly, It seems to me that the things that are best done in a windowed environment (user management, policy management, etc) have been kept in a nice GUI, whereas the things that have been traditionally configured in text files or via the command line on *nix servers have been kept that way. Quit moaning about having to actually learn how to administer a server. I don't see how IT guys in a enterprise are really going to see this as a bad thing. If they already know how to administer a *nix box, they can administer a OSX box. I can see this affecting shops that are solely OSX Server environments, but those are the exception, not the rule.

Elliot Chang writes "Over the last five years the world's honey bee population has been steadily dwindling, with many beekeepers citing 2010 as the worst year yet. In order to save these extremely important insects, scientists are working on breeding a new super honey bee that they hope will be resistant to cold, disease, mites and pesticides. If all goes well, the new and improved insect will continue to pollinate our crops for years to come."

A recent discovery of a chess journal by Luca Paccioli who was a friend and a collaborator of Da Vinci's point to the fact that some of the chess puzzles in the journal may have been drawn by Da Vinci. In fact, some of the references in Da Vinci's own manuscripts had chess references. Should that surprise us?"
