Inside Dean Kamen's Seceded Island of Geekery 187

mattnyc99 writes "The new issue of Esquire has a long, in-depth, intricate profile of Dean Kamen and his quest to invent a better world. Earlier this month, we discussed Kamen's Sterling-electric car, but this piece goes into much more detail about how that engine works — he got the original idea from the upmodded Henry Ford artifact in the basement of his insane island lab — and about how his inventions often go overlooked, including the Slingshot water purifier that Stephen Colbert made famous but that no one has actually bought yet. Quoting: 'To get the Slingshot to the 20 percent of the world that doesn't have electricity, Kamen came up with the idea of splitting it in half. Leaving the Stirling aside, he would try to develop a market for his distiller in parts of the developing world that have electricity but not reliable clean water. "There are five hundred thousand little stores in Mexico," he says. "If we can put one of these in 10 percent of them, that's enough to put it in production." That may be the killer app for the distiller.' So, is this guy all hype with overpriced devices, or is time for someone to take his genius (Segway aside) to the mass market?"

Anathem 356

Max Tardiveau writes "I just finished reading Neal Stephenson's latest novel, Anathem. I was awaiting it with some anticipation because I absolutely loved Stephenson's best-known novels: Snow Crash, The Diamond Age, and Cryptonomicon. One of Stephenson's non-fiction pieces, called In the beginning was the command line, simply wowed me when I read it. The man can write. A few years ago, I got really excited when I heard that he was writing a whole cycle of novels (the Baroque cycle). But I read the first book of the cycle — Quicksilver — and I was somewhat disappointed, so I skipped the rest of the cycle. I realize that many people enjoyed these novels, but I was hoping that Stephenson would get back his old style and inspiration. So, when Anathem was announced, I was full of anticipation — was this going to be the one? Would he find his mark again?" Keep reading for Max's impressions of Anathem

History of the LED — the Movie 106

ptorrone writes "MAKE Magazine has a fantastic 'Connections'-style video called THE LED — The short documentary has the history of the LED to modern day applications. Starting with the work of Russian Oleg Vladimirovich Losev, which was largely ignored in the 1920s, to making your own 'Cat's Whisker' — a primitive LED made from a metal-semiconductor point-contact junction forming a Schottky barrier diode. The first practical visible-spectrum LED was developed in 1962 by Nick Holonyak Jr., while working at General Electric Company."

Machine Condenses Drinking Water Out of Thin Air 438

longacre writes "A new $1,200 machine that uses the same amount of power as three light bulbs promises to condense drinkable water out of the air. On display at Wired Magazine's annual tech showcase, the WaterMill 'looks like a giant golf ball that has been chopped in half: it is about 3ft in diameter, made of white plastic, and is attached to the wall. It works by drawing air through filters to remove dust and particles, then cooling it to just below the temperature at which dew forms. The condensed water is passed through a self-sterilising chamber that uses microbe-busting UV light to eradicate any possibility of Legionnaires' disease or other infections. Finally, it is filtered and passed through a pipe to the owner's fridge or kitchen tap.'"

Is Open Source Software a Race To Zero? 729

gozunda writes "My company is an open source software vendor/developer. We maintain a popular open source project and keep ourselves afloat by producing commercial products derived from or extending the value of the core project. Over time we've seen our business model eroding as other open source projects produce free versions of the same extensions and utilities that are our bread and butter. Something that was worth $5K last year is suddenly worth $0 because the free version is just as good as the paid. This same cycle is obviously having an impact on pure-play commercial software vendors. Is open source ultimately a race to zero? In ten years will there be any cost associated with commodity (non-custom) software? If not, will there still be a 'software industry' as it exists today, or will software simply be a by-product of the operation of other industries? Is that a good thing or a bad thing? As a professional developer, do I need to fear this or feed it?"

NVIDIA's $10K Tesla GPU-Based Personal Supercomputer 236

gupg writes "NVIDIA announced a new category of supercomputers — the Tesla Personal Supercomputer — a 4 TeraFLOPS desktop for under $10,000. This desktop machine has 4 of the Tesla C1060 computing processors. These GPUs have no graphics out and are used only for computing. Each Tesla GPU has 240 cores and delivers about 1 TeraFLOPS single precision and about 80 GigaFLOPS double-precision floating point performance. The CPU + GPU is programmed using C with added keywords using a parallel programming model called CUDA. The CUDA C compiler/development toolchain is free to download. There are tons of applications ported to CUDA including Mathematica, LabView, ANSYS Mechanical, and tons of scientific codes from molecular dynamics, quantum chemistry, and electromagnetics; they're listed on CUDA Zone."

How to Deal With an Aging Brain? 684

An anonymous reader writes "I'm sure this is something all older Slashdotters are aware of: as I get older my once-sharp brain is, well, getting worse. In particular, I'm not able to remember things as well as I once did. As a geek my capacity in this area was always what defined me as a geek. Nowadays things seem to go in OK, but then leak out. A few weeks later I've mostly forgotten. So, I ask Slashdot: how do you cope with your mind getting older? What's your trick? Fish-oil? Brain Training on the DS? Exercise? Or just trying harder to remember things?"

Holiday Art Executed In Google Documents 72

CyberKnet writes "Some enterprising folks over at Google have collaborated via Google Documents to create holiday art using cells in a spreadsheet as the pixels. A time delay video was taken and is available over at YouTube and the result is pretty spectacular. More info on how they did this is available behind the scenes. They're inviting people to share their own masterpieces or post a video response over on YouTube."

Can You Be Denied the Right To Support OSS? 212

jerico.dev writes "I am currently selecting a CM tool for a project. Important condition: the software must be OSI compliant. I considered Alfresco, since they call themselves 'open source.' Then I heard from several of Alfresco's partners that they are not allowed to do projects based on Alfresco's GPL edition because their partnership contract denied them the right to do so. They only can support Alfresco's enterprise edition. But Alfresco's VP of business development Matt Asay told me that their enterprise edition is not OSI compliant. Does anyone in the Slashdot crowd have experience with partner contracts of other OSS vendors? Is it normal that Sun, Red Hat, etc. force their partners to decline projects based on their open source editions? It's probably legal to do so, but do you think it is legitimate and fair?"

Internet Explorer 8 Delayed Until 2009 204

Barence writes "Microsoft has confirmed that Internet Explorer 8 will not be officially released until 2009. According to a blog posting on the Internet Explorer 8 development site, a release candidate of the browser will be released in the first quarter of next year, to be followed by a final release at an unspecified date. This news comes on the same day that Google is considering bundling its Chrome browser with new PCs. Will the IE delay and Google's tactics help to steer users in Chrome's direction?"

GTA IV DLC Announced 49

Rockstar Games recently announced upcoming downloadable content for Grand Theft Auto IV, entitled The Lost and Damned. It's due out on February 17th, and it focuses on a member of a Liberty City biker gang, rather than Niko Bellic. Joystiq has some early screenshots. "In the original game, Niko crossed paths with The Lost several times. This time, Niko has only a bit part, [Rockstar's Dan Houser] says. 'The story is not directly impacted by decisions you took in the main game,' he says. But 'tons of details and mysteries from the main story get explained, so it will add a lot of color to the main story.'"

DARPA's IBM-Led Neural Network Project Seeks To Imitate Brain 170

An anonymous reader writes "According to an article in the BBC, IBM will lead an ambitious DARPA-funded project in 'cognitive computing.' According to Dharmendra Modha, the lead scientist on the project, '[t]he key idea of cognitive computing is to engineer mind-like intelligent machines by reverse engineering the structure, dynamics, function and behaviour of the brain.' The article continues, 'IBM will join five US universities in an ambitious effort to integrate what is known from real biological systems with the results of supercomputer simulations of neurons. The team will then aim to produce for the first time an electronic system that behaves as the simulations do. The longer-term goal is to create a system with the level of complexity of a cat's brain.'"

Setting Up a Home Dev/Testing Environment? 136

An anonymous reader writes "I'm a Project Manager (hold the remarks) who recently decided that I want/need to get my dev skills more up-to-date, as more projects are looking for their PM's to be hands-on with the development. Looking around my house, I have quite the collection of older (read: real old — it's been a while) PCs — it's pretty much a PC graveyard. Nothing that would really help me set up a nice dev infrastructure for developing web/database apps. So, my question is as follows: Should I buy a number of cheaper PC's, or should I buy one monster machine and leverage (pick your favorite) virtual machine technology?"

How To Help Our Public Schools With Technology? 378

armorer writes "I'm a programmer engaged to an inner-city public school teacher. I've been thinking for a long time now about what I can do to help close the technology gap, and I finally did something (very small) about it. I convinced my company to give me a few old computers they were replacing, refurbished them, installed Edubuntu on them, and donated them to her classroom. I also took some vacation time to go in, install everything, and give a lesson on computers to the kids. It was a great experience, but now I know first-hand how little technology these schools have. I only helped one classroom. The school needs more. (Really the whole district needs more!) And while I want to help them, I don't really know how. With Thanksgiving a week away and more holidays approaching, I suspect I'm not the only one thinking about this sort of thing. I know it's a hard problem, so I'm not looking for any silver bullets. What do Slashdot readers do? What should I be doing so that I'm more effective? How do you find resources and time to give back?"

A Web App For Real-Time Collaborative Writing 157

adamengst writes in with good news for anyone who needs to collaborate remotely on a writing or editing project — coding too. It's especially good news for those using Windows and Linux. Mac users have had SubEthaEdit for a few years now. With EtherPad, two or more people can edit a document and see all the edits simultaneously. EtherPad's main differences from SubEthaEdit: it's a Web application that de facto supports many platforms without the need for a central Mac OS X host; and it's free. Here is a comparison of EtherPad and SubEthaEdit.
