The Rules of the Swarm 166

Hugh Pickens writes "Researchers are starting to discover the simple rules that allow swarms of thousands of relatively simple animals to form a collective brain able to make decisions and move like a single organism. To get a sense of swarms, Dr. Iain Couzin, a mathematical biologist at the Collective Animal Behaviour Laboratory at Princeton University, builds computer models of virtual swarms with thousands of individual agents that he can program to follow a few simple rules. Among the findings are that swarm behavior has patterns common to many different species, that just as liquid water can suddenly begin to boil, swarm behavior can also change abruptly in character, and that just a few leaders can guide a swarm effectively by creating a bias in the swarm's movement that steers it in a particular direction. The rules of the swarm may also apply to the cells inside our bodies and researchers are working with cancer biologists to discover the rules by which cancer cells work together to build tumors or migrate through tissues. Even brain cells may follow the same rules for collective behavior seen in locusts or fish. "How does your brain take this information and come to a collective decision about what you're seeing?" Dr. Couzin says. The answer, he suspects, may lie in our inner swarm."

ATI Driver Flaw Exposes Vista Kernel to Attackers 248

Shack0ption writes "An unpatched flaw in an ATI driver was at the center of the mysterious Purple Pill proof-of-concept tool that exposed a way to maliciously tamper with the Windows Vista kernel. The utility, released by Alex Ionescu and yanked an hour later after the kernel developer realized that the ATI driver flaw was not yet patched, provided an easy way to load unsigned drivers onto Vista — effectively defeating the new anti-rootkit/anti-DRM mechanism built into Microsoft's newest operating system. Ionescu confirmed his tool was exploiting a vulnerability in an ATI driver — atidsmxx.sys, version 3.0.502.0 — to patch the kernel to turn off certain checks for signed drivers. This meant that a malicious rootkit author could essentially piggyback on ATI's legitimately signed driver to tamper with the Vista kernel."

The Future of Putting Chips Inside Our Brains 106

Roland Piquepaille writes "Researchers at the University of Florida (UF) have developed chips which someday might be inserted in the brains of people affected by epilepsy or who have lost a limb. These neuroprosthetic chips 'can interpret signals in the brain and stimulate neurons to perform correctly.' The University claims this is the future of medicine. This is maybe a little bit extreme. Just the same, the researchers are already studying these chips with rats and hope to have a prototype ready within 4 years that could be tested on humans."

Any "Pretty" Code Out There? 658

andhow writes "Practically any time I hear a large software system discussed I hear "X is a #%@!in mess," or "Y is unmanageable and really should be rewritten." Some of this I know is just fresh programmers seeing their first big hunk o' code and having the natural reaction. In other cases I've heard it from main developers, so I'll take their word for it. Over time, it paints a bleak picture, and I'd be really like to know of a counterexample. Getting to know a piece of software well enough to ascertain its quality takes a long time, so I submit to the experience of the readership: what projects have you worked on which you felt had admirable code, both high-level architecture and in-the-trenches implementation? In particular I am interested in large user applications using modern C++ libraries and techniques like exception handling and RAII."

Earthlike Planet Orbiting Nearby Star 617

The Bad Astronomer writes "Astronomers in Europe have announced the discovery of a planet with only 5 times the Earth's mass, orbiting a red dwarf star 20 light years away. It orbits the star so closely that it only takes 13 days to go around... but the star is so cool that the temperature of the planet is between 0 and 40 Celsius. At this temperature there could be liquid water. Models indicate the planet is either rocky like the Earth or covered in an ocean. While it's not known if there actually is liquid water on the planet, this is a really big discovery, and indicates that we are getting ever closer to finding another Earth orbiting an alien star."

Hardware Implants Mimic Brain Cells 230

An anonymous reader writes "PopSci is reporting that Ted Berger, a USC scientist, has been working to engineer a brain implant the mimics the functions of neurons. Early tests on rat brain cells have shown promise, and if successful, Berger's implant could remedy everything from Alzheimer's to absent-mindedness — and reduce memory loss to nothing more than a computer glitch"

Is Simplified Spelling Worth Reform? 1183

digitalhermit writes "I guess many folks are of very little brain, and big words bother them... There's a push for simpler spelling. Instead of 'weigh' it would be 'way.' 'Dictionary' would be 'dikshunery' and so forth. Dunno if it's a joke, but it seems in earnest. Mark Twain must be spinning around somewhere." Twain is often credited with the satirical call for spelling reform called "A Plan for the Improvement of English Spelling," though according to Wikipedia, Twain was "actually a supporter of reform," and the piece may have been written by M.J. Shields. Benjamin Franklin was another champion of spelling reform, and even came up with a phonetic alphabet to implement such reform.

Jimmy Wales Starting Campaign Wikis 134

Billosaur writes "Jimmy Wales, self-described creator of the Wikipedia, is apparently trying to bring the functionality offered by the Internet encyclopedia to a new realm: politics and political campaigns. He is starting a new website, the Campaigns Wikia, which 'has the goal of bringing together people from diverse political perspectives who may not share much else, but who share the idea that they would rather see democratic politics be about engaging with the serious ideas of intelligent opponents, about activating and motivating ordinary people to get involved and really care about politics beyond the television soundbites.' Sounds intriguing, but one has to wonder if it will be plagued by internecine feuding, punditry, and political manipulation."

GNOME Reaches Out to Women 672

Dominic Hargreaves writes "This year GNOME received 181 applications to Google's Summer of Code program, yet none were from women. As a result, they've decided to address this imbalance by launching an outreach program to sponsor three female students to work on GNOME-related projects this summer." Most any science department will tell you that the amount of interest and involvement of women pales next to men of similar age and background. Is this sponsorship a creative way to get women interested in GNOME, or is it merely sexist?

HomeStar - 21st Century Home Planetarium Review 98

Jeff writes "Direct from Japan, the SegaToys HomeStar is a unique home projector that turns any room into a planetarium, giving a clear view of the night sky. Using interchangeable plates, it's capable of displaying up to 10,000 stars of either northern or southern hemisphere, as well as their constellations. The starfield can move on a timer to simulate the earth's rotation. Also comes with a meteor generating function and sleep timer. Makes a great gift for the dad who has everything, or people who live in light-polluted areas." Check out Jeff's review of the unit.

Another Google Tool To Take On PayPal? 219

An anonymous reader writes to mention a ZDNet post about another possible product in the grand Google vision. The product, Google Checkout, may be an attempt to go after PayPal. From the article: "Since we know Google is behind its registration, what is Google Checkout going to be? I think it will be a shopping cart system to help websites accept payment for their items online. The money site owners make will be deposited into a holding account at Google -- just like AdSense works. Isn't this starting to sound a lot like PayPal? Who knows, they could even offer a Google branded Mastercard "debit card" like PayPal's ATM/Debit Card -- after all, the domain googlemastercard.com is registered to Google too."

Does Philosophy Have a Role in Computer Science? 239

Johannes Climacus asks: "It would seem to me that philosophical works of philosophers such as Aristotle, Leibniz, Frege, Russell, and Tarski could play a central role in a Computer Science curriculum, as they form a mathematical basis of modern CS and Math. Ethicists such as Plato, Kant, Hegel, Mill, and Heidegger might also play a normative role in Computer Ethics and technology in general. However, I haven't seen any philosophical discussion in any of my theoretical computer science courses besides some simple logic. Is it the same elsewhere? How often do philosophical concerns play into Computer Science education as a whole? What role does (or could) philosophy have in Computer Science or Information Technology?"

Henry's Python Programming Guide 143

An anonymous reader writes "Seems like someone else has put up another Python programming guide, although this one seems to be a little easier to get through. From the article: 'My name is Henry the Adequate, and I am a Python programming Guru. I know all of their movies, and their TV shows, and can quote the dead parrot sketch in my sleep. In fact I do quote it in my sleep. That may explain why I am single, although it could also have something to do with the flamethrower. Naturally many old-timers want to know what this new-fangled Python thing is all about. "Henry," they say, "What is this new-fangled Python thing all about?" See what i mean? So, here, at last, is the article you have all been waiting for...'"

Stallman Selling Autographs 335

UltimaGuy writes "Sports stars, musicians, and other celebrities have been charging for autographs for years, but who would have thought Richard Stallman would be doing the same? Is this just for fun, or a clever, highly effective protest? Hackers, geeks and nerds gathered together at the 7th FISL - Internacional Free Software Forum, in Porto Alegre (Brazil) last week, were astounded when they got word that Richard Stallman, the founding father of the Free Software Foundation and creator of the GPL, was charging R$ 10 (about US$ 3) for an autograph and R$ 5 (less than US$ 2) to get his picture taken by free software enthusiasts at the event floor."
