Prison Inmates Catfished $560,000 Out of Military Service Members in Sextortion Scam, NCIS Says (gizmodo.com)
Hundreds of military service members reportedly got caught up in a sextortion scam run by prison inmates using cellphones, according to a release issued by the Naval Criminal Investigative Service (NCIS). From a report: Military agents from multiple criminal investigation groups have served summons and issued warrants for arrests related to the scheme. According to the NCIS, South Carolina and North Carolina prison inmates, assisted by outside accomplices, sought out service members through dating sites and social media, then took on false identities, feigned romantic interest, and exchanged photos.
Once the inmates had successfully catfished their targets, they would then pose as the father of the fake persona, insisting their child was underage and that the target had therefore committed a crime by exchanging photos. In some situations, the "father" claimed he wouldn't press charges if the target gave him money. Sometimes the catfisher would pose as law enforcement requesting money for the family. -
Navy, Marines Prohibit Sharing Nude Photos In Wake of a Facebook Scandal (fortune.com)
An anonymous reader quotes a report from Fortune: The Navy and Marine Corps issued new regulations that ban members from sharing nude photographs following a scandal involving military personnel sharing intimate pictures of their female colleagues -- some of which were taken without their knowledge -- in a secret Facebook group. The new statute, which was signed Tuesday by Acting Navy Secretary Sean Stackley, went into effect immediately and will be made permanent when the next edition of the Navy's regulations is printed, according to Navy Times. Military courts will handle violations of the new rule. The crackdown comes after a Facebook group was uncovered featuring naked photos of female service members. The group was eventually shut down by Facebook after a request from the Marine Corps. The Center for Investigative Reporting found that some of the photographs posted on the Facebook group may have been taken consensually, but others may not have been. -
A Guide To Friday's Comet-Eclipse-Full-Moon Triple Feature (cnet.com)
SonicSpike quotes a report from CNET: Even if you aren't a space nerd whose idea of a good time is craning your neck to stare into the vast nothingness of space on a frigid evening, this Friday the heavens will put on a show worth heading outdoors for. A penumbral lunar eclipse, a full "snow moon" and a comet will be spicing up the night sky February 10 in a rare convergence of such celestial happenings. We'll start with our nearest neighbor. February brings the full moon known as the "snow moon" because this month in North America tends to see a lot of the white fluffy stuff. This snow moon will be special though because, well... we'll all get in its way in a sense when the penumbral lunar eclipse takes place Friday. The eclipse will be at least partly visible from most but not all places on Earth (sorry Australia and Japan). The moment of greatest eclipse is at 4:43 p.m. PT and the eclipse will then dissipate until it completes a little over two hours later, according to the U.S. Naval Observatory. Next up, Comet 45P/Honda-Mrkos-Pajdusakova has actually been visible with binoculars and telescopes for several weeks already, but it will be at its closest approach to Earth on the morning of February 11 as it passes by at a distance of 7.4 million miles (11.9 million kilometers) or 30 times further away than the moon. -
US Navy Decommissions the First Nuclear-Powered Aircraft Carrier (engadget.com)
An anonymous reader quotes a report from Engadget: The Navy has decommissioned the USS Enterprise (CVN-65), the world's first nuclear-powered aircraft carrier. The vessel launched in 1961 and is mainly known for playing a pivotal role in several major incidents and conflicts, including the Cuban Missile Crisis, the Vietnam War and the 2003 Iraq War. However, it also served as the quintessential showcase for what nuclear ships could do. Its eight reactors let it run for years at a time, all the while making more room for the aircraft and their fuel. As you might guess, the decommissioning process (which started when the Enterprise went inactive in 2012) is considerably trickier than it would be for a conventional warship. It wasn't until December 2016 that crews finished extracting nuclear fuel, and the ship will have to be partly dismantled to remove the reactors. They'll be disposed of relatively safely at Hanford Site, home of the world's first plutonium reactor. Whatever you think of the tech, the ship leaves a long legacy on top of its military accomplishments. It proved the viability of nuclear aircraft carriers, leading the US to build the largest such fleet in the world. Also, this definitely isn't the last (real-world) ship to bear the Enterprise name -- the future CVN-80 will build on its predecessor with both more efficient reactors and systems designed for modern combat, where drones and stealth are as important as fighters and bombers. It won't be ready until 2027, but it should reflect many of the lessons learned over the outgoing Enterprise's 55 years of service. -
US Military Using $600K 'Drone Buggies' To Patrol Camps In Africa (cnbc.com)
An anonymous reader quotes a report from CNBC: The U.S. military is using an unmanned robotic vehicle to patrol around its camps in the Horn of Africa. The remote controlled vehicle is the result of a 30-year plan after military chiefs approved the concept of a robotic security system in 1985. Now the Mobile Detection Assessment and Response System, known as MDARS, are carrying out patrols in the east African country of Djibouti, under the control of the Combined Joint Task Force-Horn of Africa. The area is known as home to a number of hostile militant groups including the al-Qaeda-affiliated al-Shabaab. An operator sits in a remote location away from the vehicle watching the terrain via a camera link which is fixed to the chassis. U.S. military software engineer Joshua Kordanai said in a video presentation that the vehicle drives itself, freeing the remote operator to monitor video. "The vehicle has an intruder detection payload, consisting of radar, a night vision camera, a PTZ [pan-tilt-zoom] camera and two-way audio, so the system will be able to detect motion," he added. One report prices the cost of an earlier version of the military 'drone buggy' at $600,000 each. -
New Molecular Transistor Can Control Single Electrons
Eloking writes: An international team of scientists has been able to create a microscopic transistor made up of one single molecule and a number of atoms. Gizmag reports: "Researchers from Germany, Japan and the United States have managed to create a tiny, reliable transistor assembled from a single molecule and a dozen additional atoms. The transistor reportedly operates so precisely that it can control the flow of single electrons, paving the way for the next generation of nanomaterials and miniaturized electronics." The team that conducted the research included teams from the U.S. Naval Research Laboratory and the NTT Basic Research Laboratories in Japan. -
Breakthough Makes Transparent Aluminum Affordable
frank249 writes: In the Star Trek universe, transparent aluminum is used in various fittings in starships, including exterior ship portals and windows. In real life, Aluminium oxynitride is a form of ceramic whose properties are similar to those of the fictional substance seen in Star Trek. It has a hardness of 7.7 Mohs and was patented in 1980. It has military applications as bullet-resistant armor, but is too expensive for widespread use.
Now, there has been a major breakthrough in materials science. After decades of research and development, the U.S. Naval Research Laboratory has created a transparent, bulletproof material that can be molded into virtually any shape. This material, known as Spinel (magnesium aluminate), is made from a synthetic powdered clay that is heated and pressed under vacuum into transparent sheets. Spinel weighs just a fraction of a modern bulletproof pane. -
US Navy Researchers Get Drones To Swarm On Target
coondoggie writes: The Office of Naval Research today said it had successfully demonstrated a system that lets small-unmanned aircraft swarm and act together over a particular target. The system, called Low-Cost UAV Swarming Technology (LOCUST) features a tube-based launcher that can send multiple drones into the air in rapid succession. The systems then use information sharing between the drones, allowing autonomous collaborative behavior in either defensive or offensive missions, the Navy said. -
US NAVY Sonar/Lidar Editing Software Released To the World
New submitter PFMABE writes The Naval Oceanographic Office (NAVO) has spent 16 years developing the Pure File Magic Area Based Editor (PFMABE) software suite to edit the huge volumes of lidar and sonar data they collect every year. In accordance with 17 USC 105, copyright protection is not available to any work of the US government. Originally developed to run on RedHat OS with network distributed storage, it has been migrated to Windows 7. This software, and accompanying source code (Win & Linux), has been released to the public domain at pfmabe.software, free for download with registration. -
Tor Project Mulls How Feds Took Down Hidden Websites
HughPickens.com writes: Jeremy Kirk writes at PC World that in the aftermath of U.S. and European law enforcement shutting down more than 400 websites (including Silk Road 2.0) which used technology that hides their true IP addresses, Tor users are asking: How did they locate the hidden services? "The first and most obvious explanation is that the operators of these hidden services failed to use adequate operational security," writes Andrew Lewman, the Tor project's executive director. For example, there are reports of one of the websites being infiltrated by undercover agents and one affidavit states various operational security errors." Another explanation is exploitation of common web bugs like SQL injections or RFIs (remote file inclusions). Many of those websites were likely quickly-coded e-shops with a big attack surface. Exploitable bugs in web applications are a common problem says Lewman adding that there are also ways to link transactions and deanonymize Bitcoin clients even if they use Tor. "Maybe the seized hidden services were running Bitcoin clients themselves and were victims of similar attacks."
However the number of takedowns and the fact that Tor relays were seized could also mean that the Tor network was attacked to reveal the location of those hidden services. "Over the past few years, researchers have discovered various attacks on the Tor network. We've implemented some defenses against these attacks (PDF), but these defenses do not solve all known issues and there may even be attacks unknown to us." Another possible Tor attack vector could be the Guard Discovery attack. The guard node is the only node in the whole network that knows the actual IP address of the hidden service so if the attacker manages to compromise the guard node or somehow obtain access to it, she can launch a traffic confirmation attack to learn the identity of the hidden service. "We've been discussing various solutions to the guard discovery attack for the past many months but it's not an easy problem to fix properly. Help and feedback on the proposed designs is appreciated."
According to Lewman, the task of hiding the location of low-latency web services is a very hard problem and we still don't know how to do it correctly. It seems that there are various issues that none of the current anonymous publishing designs have really solved. "In a way, it's even surprising that hidden services have survived so far. The attention they have received is minimal compared to their social value and compared to the size and determination of their adversaries." -
Navy Creates Fuel From Seawater
New submitter lashicd sends news that the U.S. Naval Research Laboratory has announced a successful proof-of-concept demonstration of converting seawater to liquid hydrocarbon fuel. They used seawater to provide fuel for a small replica plan running a two-stroke internal combustion engine. "Using an innovative and proprietary NRL electrolytic cation exchange module (E-CEM), both dissolved and bound CO2 are removed from seawater at 92 percent efficiency by re-equilibrating carbonate and bicarbonate to CO2 and simultaneously producing H2. The gases are then converted to liquid hydrocarbons by a metal catalyst in a reactor system. ... NRL has made significant advances in the development of a gas-to-liquids (GTL) synthesis process to convert CO2 and H2 from seawater to a fuel-like fraction of C9-C16 molecules. In the first patented step, an iron-based catalyst has been developed that can achieve CO2 conversion levels up to 60 percent and decrease unwanted methane production in favor of longer-chain unsaturated hydrocarbons (olefins). These value-added hydrocarbons from this process serve as building blocks for the production of industrial chemicals and designer fuels." -
Navy Database Tracks Civilians' Parking Tickets, Fender-Benders
schwit1 (797399) writes with this excerpt from the Washington Examiner: "A parking ticket, traffic citation or involvement in a minor fender-bender are enough to get a person's name and other personal information logged into a massive, obscure federal database run by the U.S. military. The Law Enforcement Information Exchange, or LinX, has already amassed 506.3 million law enforcement records ranging from criminal histories and arrest reports to field information cards filled out by cops on the beat even when no crime has occurred." -
US Navy Launches Drone From Submerged Submarine
Hugh Pickens DOT Com writes "MarineLink reports that a fuel cell-powered, unmanned aerial system (UAS) aircraft has been successfully launched from the submerged 'USS Providence' (SSN 719). The drone flew a several-hour mission demonstrating live video capabilities streamed back to the submarine, offering a pathway to providing mission critical intelligence, surveillance and reconnaissance (ISR) capabilities to the U.S. Navy's submarine force. 'Developing disruptive technologies and quickly getting them into the hands of our sailors is what our SwampWorks program is all about,' says Craig A. Hughes, Acting Director of Innovation at the Office of Naval Research. 'This demonstration really underpins ONR's dedication and ability to address emerging fleet priorities.' The XFC UAS — eXperimental Fuel Cell Unmanned Aerial System — was fired from the submarine's torpedo tube using a 'Sea Robin' launch vehicle system designed to fit within an empty Tomahawk launch canister (TLC) used for launching Tomahawk cruise missiles already familiar to submarine sailors. Once deployed from the TLC, the Sea Robin launch vehicle with integrated XFC rose to the ocean surface, where it appeared as a spar buoy. Upon command of Providence's Commanding Officer, the XFC then vertically launched from Sea Robin and flew a successful mission." -

Comet ISON Approaches Perihelion
New submitter BugNuker writes "Comet ISON has been speeding towards the sun, and while doing so, it has been getting brighter. There was hope that ISON would be 'Comet of the Century' material. That does not seem to be the case, but it still exists and it's still very interesting. Recently, ISON has undergone some outbursts, making it a near naked-eye object. ISON is still approaching perihelion (it will get there at 18:25 UTC on 28 November). For now, we can keep watching the STEREO spacecraft images for more evidence." Emily Lakdawalla of the Planetary Society put together this animated GIF of the comet from images taken by the STEREO-A spacecraft. Karl Battams put together a fascinating GIF as well. The Planetary Society has a list of information feeds and scheduled events for keeping tabs on ISON. -
Liquid Hydrogen Powers a UAV For a Cool 48 Hours
An anonymous reader writes "While liquid hydrogen may not be a mainstream fuel for drones, the aerospace industry has said it holds the promise of flight endurance on the order of days, seemingly just another far-fetched aerospace industry pitch ... until now. The Naval Research Laboratory just announced that the Ion Tiger, a diminutive 37-pound airplane with a 17 foot wingspan, flew for 48 hours and 1 minute on liquid hydrogen and a fuel cell (anyone else notice the oddly specific duration? Guess it's better than 47 hours 59 minutes). This is a dramatically different scale than the liquid hydrogen powered 150 foot wingspan Boeing Phantom Eye and 175 foot wingspan AeroVironment Global Observer, which have yet to live up to their multi-day endurance projections. Interestingly enough, the well-known Global Hawk only has an endurance of 33.1 hours, which barely cracks Wikipedia's list of notable UAV endurance flights. Of course, solar-electric airplanes have flown for two weeks continuously, but that sure seems like refueling!" -

U.S. Navy Receives First Industry Built Railgun Prototype
Zothecula writes "Two years after BAE Systems was awarded a US$21 million contract from the Office of Naval Research (ONR) to develop an advanced Electromagnetic Railgun for the U.S. Navy, the company has delivered the first industry-built prototype demonstrator to the Naval Surface Warfare Center (NSWC) Dahlgren. The prototype launcher is now being prepared for testing which is scheduled to take place in the coming weeks." -
Milky Way Magnetic Fields Charted
eldavojohn writes "Using radio telescope data, scientists from around the world have plotted the Milky Way Galaxy's magnetic field in the form of Faraday Depth. From the article, 'For 150 years, scientists have measured cosmic magnetic field by observing the Faraday effect. They know that when polarized light passes though a magnetized medium, the plane of polarization turns. This concept is called Faraday rotation. The strength and direction of the magnetic field governs the amount of rotation that occurs. So scientists observe the rotation to investigate the magnetic fields' properties. Radio astronomers study the polarized light from distant radio source, passing through the Milky Way on the way to Earth, in order to measure our Galaxy's magnetic field. By measuring the polarization of the light sources at different frequencies, researchers can determine the amount of Faraday rotation.' In the future, radio telescope technologies like LOFAR, eVLA, ASKAP, MeerKAT and the SKA hope to provide enhanced Faraday rotation data so scientists can better understand turbulence in galactic gas and these galactic magnetic field structures." -
Cold-War Missile Launches Military Satellite
Velcroman1 writes "At 11:49 a.m. EDT, a Minotaur IV+ rocket — essentially a decommissioned Peacekeeper missile built decades ago during the Cold War — launched the TacSat-4 satellite into orbit. Most troops today carry PRC-117 radios for communication, devices that rely on UHF transmissions. They relay calls and data back to a base station that's brought in and fixed in place, either set up on a hillside locally or carried overhead in a nearby plane. The TacSat-4 (or tactical microsatellite) lets the hundreds of thousands of military handheld radios currently in use communicate directly with an antenna orbiting in the most convenient spot imaginable: all that space overhead. 'If you're a mobile force, that requires a mobile infrastructure, the best place to put that infrastructure is in space,' said Dr. Larry Schuette, director of innovation for the Navy's Office of Naval Research (ONR)." -
US Navy Close To On-Ship Laser Cannons
An anonymous reader writes "The Office of Naval Research and industry partner Northrop Grumman said they successfully tested for the first time an on-board laser defense system known as the Maritime Laser Demonstrator (MLD), using it to destroy a small target vessel. The test actually accomplished several other benchmarks, including integrating MLD with a ship's radar and navigation system, and firing an electric laser weapon from a moving platform at-sea in a humid environment." -
Navy Scientists Develop Laser For Underwater Communication
Researchers at the Naval Research Laboratory claim to have come up with a better tool for underwater acoustics. The new system uses laser light to create sound underwater from a distance. This technology could allow planes a much easier method of communicating with submarines without the need for a floating buoy. "Efficient conversion of light into sound can be achieved by concentrating the light sufficiently to ionize a small amount of water, which then absorbs laser energy and superheats. The result is a small explosion of steam, which can generate a 220 decibel pulse of sound. Optical properties of water can be manipulated with very intense laser light to act like a focusing lens, allowing nonlinear self-focusing (NSF) to take place. In addition, the slightly different colors of the laser, which travel at different speeds in water due to group velocity dispersion (GVD), can be arranged so that the pulse also compresses in time as it travels through water, further concentrating the light. By using a combination of GVD and NSF, controlled underwater compression of optical pulses can be attained." -
US Nuclear Sub Crashes Into US Navy Amphibious Vessel
Kugrian writes "Showing that it's not just the British and the French who have trouble seeing each other on the high seas, a US Nuclear submarine yesterday crashed into a US Navy heavy cruiser. The USS Hartford, a nuclear-powered attack submarine, was submerged as it crashed into the USS New Orleans in the strait of Hormuz, resulting in the spillage of 95,000 litres of diesel fuel. Both vessels were heading in the same direction when the collision occurred in the narrow strait and were subsequently heading to port for repairs. A spokesman for the 5th Fleet said that the USS Hartford suffered no damage to its nuclear propulsion system." According to the USS New Orleans' Wikipedia page, it's actually an amphibious transport dock. -

US DoD Poll On Leap Seconds
@10u8 writes "For time scales to leap, or not to leap, has been the question here before. The ITU-R will be considering leap seconds again in a few weeks. This week the USNO posted a survey about leap seconds by the US DoD. The issue has civil implications as well as technical ones, and there is a demonstrated way to respect the history, remove leaps from navigation and POSIX time, yet keep the sun overhead at noon." -
Leap Second At The End of 2005
Ruff_ilb writes "Because of the discrepency between an ephemeris second (the fraction 1/31,556,925.9747 of the tropical year for 1900 January 0 at 12 hours ephemeris time) and the second of atomic time (the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom), we're left with more than leap years. In order to ensure that the the atomic time and civil stay coordinated, "Civil time is occasionally adjusted by one second increments to ensure that the difference between a uniform time scale defined by atomic clocks does not differ from the Earth's rotational time by more than 0.9 seconds."" And Happy New Years everyone ;) -
Air Force Orders Up A Custom Windows Monoculture
Soulfader writes "It seems that the Air Force has not learned from the Navy's folly in single-source mammoth contracts and their attendant problems, and is now working on something similar with Dell and Microsoft. Particularly interesting is the article's assertion that the Air Force is 'fed up' with Microsoft OS problems--but not enough to switch to something else. Instead, they're going to be getting a custom 'solution' of Windows products specially configured for their use. Is this the ever-hoped-for 'good' version of Windows, or more along the line of the sucks-in-new-and-interesting-ways version of Highlander II?" -
New Solution For Your Transistor BBQ
servantsoldier writes "There's a new solution for the transistor heat problem: Make them out of charcoal... The AP is reporting that Japanese researchers, led by Daisuke Nakamura of Toyota Central R&D Laboratories Inc., have discovered a way to use silicon carbide instead of silicon in the creation of transistor wafers. The Japanese researchers discovered that they can build silicon carbide wafers by using a multiple-step process in which the crystals are grown in several stages. As a result, defects are minimized. Other benefits are decreased weight and a more rugged material. The researchers say that currently only a 3" wafer has been produced and that a marketable product is at least six years away." -
U.S. Navy to Deploy Rail Guns by 2011
Walter Francis writes "The U.S. Navy has apparently been busy. They have been focusing heavily on the next generation of weapons and propulsion systems, including Microwave, Laser, and Electromagnetic-Kinetic weapons, more commonly known as railguns. What specifically surprised me was the fact that the Navy plans to deploy these systems as early as 2011, on their DD(X) frigates. The range of these rail guns is estimated to be over 250 miles." -
America's Army - Development, Impact Analyzed
Professor writes "The MOVES Institute's America's Army team has placed a booklet on the game's development and impact (PDF link) onto the web."

Flight Sims As Effective Pilot Learning Tools
Thanks to Wired News for their article discussing the increasing use of PC flight simulators in educating real-life pilots. It references Microsoft's newest Flight Simulator 2004, and mentions: "The Navy decided to see if using Flight Simulator would help... students. It found that trainees who used the program did better in their training, prompting the Navy to issue customized versions of Flight Simulator to all of its flight students." There are still issues with using retail PC products: "Flight Simulator's limited field of view from the cockpit, and the resulting focus on the instruments that it encourages, can cause problems that need to be corrected in flight training", but overall, Microsoft's product is described as "...a highly effective tool to help student pilots learn how to fly." -

Australian Overturns 15 Years of Nano-Science Doctrine
Roland Piquepaille writes "Dr John Sader, from the University of Melbourne, discovered a design flaw in a key component of the Atomic Force Microscope (AFM). He 'used established mechanical principles to prove that the popular V-shaped cantilever inadvertently degrades the performance of the instrument, and delivers none of its intended benefits.' This finding may reshape the industry by proposing a single new standard and because the AFM 'has been the instrument of choice for three dimensional measurements at the atomic scale, since its invention in 1986.' Check this column for more details and an AFM diagram or read the original University of Melbourne's article. You also can visit the 'How AFM works' page." -
Slashback: Intuit, Telemetry, Meetup
Slashback tonight brings you updates on TurboTax and your boot sector, NASA's plans beyond the shuttle, Barry Shein on spam, Linux telemetry, and more. Read on for the details!I'd prefer an apology from the IRS. Rico writes "Intuit have spoken out about the CD-protection methods of their TurboTax software. According to them, the protection is harmless to computers and does not erase data. Despite the huge negative customer feedback, Intuit are still profiting from the product."
Train the dog, then never call the command. Mitch Wagner writes "Barry Shein, subject of this week's /. interview, proposes in "ISP Head Floats Plan To Legalize Spam" that spam is impossible to block, and so instead should be legitimized and regulated, with a central, not-for-profit company charged with collecting fees from spammers and distributing those fees to ISPs that receive the spam. Of course, there have been many other plans for charging spammers to send spam, but those plans mostly have the fees going to the ISP that sends the e-mail, or to the user that receives the mail, rather than the ISP that receives it and has to deliver it to the end-users. I'm the author of the piece I link to in this article."
Make big money as an open source telemetrist! For anyone who missed it in the Science section, there's a great followup to the Linux-based home-brewed weather balloon we recently featured: the OpenTRAC project is looking for help in building an APRS-like protocol. If that's gibberish to you, check out their introduction to the protocol to get an idea of how it's useful. Future experimenters will thank you.
One good deed escapes punishment. Psyiode writes with a link to this story at the Houston Chronicle which begins "Jurors needed only about 15 minutes to acquit a Houston man who was accused of hacking into the Harris County district clerk's wireless computer system in March. One juror, Helen Smith, 62, said she and the other jurors found that Stefan Puffer indeed hacked into the system but they did not believe he caused any damage as the government had alleged."
Puffer was arrested last summer for demonstrating that the county court's wireless LAN wasn't secure, and telling them about it.
Do we need manned spaceflight? Professor_Quail writes "The BBC has a story on NASA's plans for a successor to the Space Shuttle. From the article: Nasa has revealed its first set of mission criteria for the Orbital Space Plane (OSP) - the series of space vehicle expected to replace the space shuttle from 2012. The new spacecraft's primary function will be to ferry crews to and from the International Space Station (ISS) and serve as a lifeboat if the station has to be evacuated."

Highly recommended if you have nothing better to do on a Thursday evening." Hmmm, must check to see if there's one around Knoxville ...

Help Build An Open Tracking And Telemetry System
Rorschach1 writes "Many /.'ers are already familliar with APRS, the Automatic Position Reporting System that's been mentioned here numerous times, most recently in the article on the Linux-powered weather balloon. It's one of the coolest things going in ham radio these days, but the APRS message protocol itself is rather hairy and bloated, and suffers from a distinct lack of extensibility. The OpenTRAC project aims to fix it, but we need your help." Read on to find out the details of what sort of help they're looking for as well as some more information about the project generally."For those who don't know, APRS is a messaging system used primarily on the amateur radio 2-meter band for relaying position reports, telemetry, weather data, and other such bits of information. The network has grown to the point where it can get your packets from almost anywhere in the US (and much of the rest of the world) to one of countless Internet gateways. Writing software (especially for embedded systems) for use with APRS, though, can be a real nightmare. OpenTRAC (for Open Tactical Reporting and Communications) is an open-source effort to develop an APRS-like protocol that builds on what we've learned over the past decade of APRS use, and avoids much of the ugliness of the APRS specification.
So far, though, we've got a small handful of developers working on the project. Input from people like the hackers building Linux weather balloons and such would be much appreciated. We're also in need of someone familliar with public key cryptography, particularly ECDSA. (No, the traffic won't be encrypted - only signed.) AX.25 gurus are also welcome, though the protocol isn't restricted to AX.25.
Linux and ham radio have always shared a kind of symbiosis, and I'd really like more input from the OS side. So check out the website, read the (very much in-work) specification, and let me know what you think."

A Better Breed of GPS Software?
willo asks: "I recently built an on board computer for my Grand Cherokee. The initial uses for it include music, gps navigation, on board diagnostics and a baby cam so I can see how my kid is in that rear facing seat. After lots of research and testing, I'm really disappointed with the mapping software out there for Linux. Gpsdrive provides the basic functionality I need, but the street names are built into the image and are difficult to read at a glance while driving. Not to mention that it has to download the maps it needs ahead of time. Xastir can handle almost any map out there, but it reads through every map for each redraw! It also seems to lack the ability to zoom intelligently based on location. Note that it's not really designed to be a navigation aid, but rather a ham radio APRS tool. (I am a ham). Delorme Street Atlas USA does what I really want, but it's been a pain to make run properly under wine. Is anyone else out there working on a decent navigation application?""To be really usable navigation software should do the following:
- handle maps efficiently and draw them quickly
- have intelligently organized map sets for countries/states. (You can't download a friggin map in the middle of Montana!)
- include serial gps/gpsd support. (just about everyone has this)
Map Sources do exist for this! Bruce Perens made TIGER/line data availible. NAVTECH is the map source for pretty much all the vehicle navigation systems out there, and high resolution maps are availible from the Geographical Information Survey." -
Securing Fiber Using Light Polarization
screenbert writes: "A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they're using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines. This press release has more information. Of course I always thought that fiber was always pretty secure anyway since it's a lot harder to tap than copper." -
Parsing Algorithms and Resources?
Derek Williams asks: "I'm a senior majoring in computer engineering & computer science and I've been programming for about 7 years, mainly in C and Java. While I've had quite a few courses that delve into some of the deeper topics of programming (e.g. Object Oriented Design), I find that the majority of programs I write, both for work and elsewhere, involve parsing. Although I have no problem tackling these sorts of programs, I was wondering if there was some branch of computer science dedicated to the study of parsing. What books and websites out there are of interest to someone looking to learn more about parsing and algorithms relating to it?" -
Inside the Joint Strike Fighter Competition
jonerik writes "The June issue of the Atlantic Monthly has this account of the history of the Joint Strike Fighter competition between Boeing and Lockheed Martin (which the latter company ended up winning this past fall, with Boeing now touting its expanding line of unmanned aircraft as the true future of tactical aviation). The article does a fine job of showing how the competitors dealt with the challenge of producing an aircraft (now dubbed the F-35) that the Air Force, Navy, Marines, RAF, and Royal Navy could all live with. Funniest part: Boeing's X-32 entry, with its enormous pelican-like jet intake, had some questioning whether the plane's bizarre appearance didn't hurt its chances more than its performance. 'Helpful as my contacts at Boeing were, no one was eager to claim credit for the design of the plane,' says the article's writer James Fallows." Fascinating article. -
Slashback: Hagiography, Oracle, Fusion
Slashback with updates on RMS's biography, PVRs vs. the endangered edifice of Western Civilization, Oracle's funny deal with California, cold fusion and more. Read on for the details! Can't we please have a picture of the winner? obsidianpreacher writes: "Apparently, SETI@Home has just recently released who the winner of the 500 millionth result "contest" is, and posted the news on the SETI@Home site. Too bad it wasn't me (or one of the people who turn in 300 bajillion results per day)."Even lukewarm fusion would be satisfy me. driggers writes: "I wrote a review of the book "Excess Heat" for /. last year. I thought you might (or might not :) be interested to learn that the U.S. Navy in February 2002 issued Technical Report No. 1862 titled "Thermal and Nuclear Aspects of the Pd/D2O System," Vol. 1 of which summarizes A Decade of Research at Navy Laboratories."
Dr. Frank Gordon, Head, Navigation and Applied Sciences Department, concludes his foreword with the remark, "It is time for the government funding organizations to invest in this research."
If you modify the source you must keep it accurate, like a Mad Lib. An Anonymous Coward writes "I just noticed the biography of Richard M. Stallman, "Free as in Freedom" by Sam Williams is online at oreilly, released under the GNU Free Documentation License."
What vapors rule the modern day Oracle? MarkedMan writes: "The following CNET article outlines Oracle's reply to the State of California's announcement it was canceling a nearly $100 million dollar contract. It should not come as a surprise, as few companies would give up that kind of money without a fight, not to mention the domino effect if they just rolled over. It would be a tacit admission that they ripped off naive customers."

Cold Fusion Conference Counts Eleven Labs
James Salsman writes: "From an American Physical Society conference session held a week ago, there appear to be now eleven institutions actively publishing cold fusion results: Research Systems (Arlington, VA), SRI International, ENEA (Italy), JET Energy (Welleslley, MA), Middle Tennessee State Univ., Russian Academy of Sciences, U. of Il. at Urbana-Champaign, U.S. Navy's SPAWAR Systems Center in San Diego, First Gate Energy (Woodside, CA, and a few blocks from my house), New Energy Research Lab.

Follow Up on USNA Shoestring Satellite
NotFabio writes: "I received this e-mail from the USNA satellite team. Seems the sattelite is not only still functioning, but they plan to do a test tonight. If you're out looking at the leonids, try to spot it if you can. They're kind of hopeful it will be spotted somewhere. They plan to turn on the 50 onboard Red LEDS for 5 minutes beginning at 9:35PM Eastern Standard Time on Saturday night, when the satellite will be overhead at New Orleans. It should pass over Alabama, Kentucky, Ohio, Lake Erie, Toronto and finally over northern Canada at 9:41 PM. Apparently there's no attitude control, so they don't know exactly where the thing will point, meaning anyone on the eastern half of the US and Canada has a chance of spotting it." -
Cross Country Solar Race
Dorm writes: "The American Solar Challenge, a 2300-mile cross country solar-powered car race begins on Sunday in Chicago. The 10-day race follows old Route 66 (parallels I-55 from Chicago to St. Louis, I-44 from St. Louis to Oklahoma City, and I-40 from Oklahoma City to Los Angeles) to downtown Claremont, California where teams will cross the finish line on the afternoon of July 25th. If you live along the race route or will be in the area, take a look at the media stop schedule on the ASC site and stop by to see some of the cars during the race. Some teams (including ours, Iowa State) will also be displaying their cars Saturday on the front lawn of the Museum of Science and Industry in Chicago, where the race begins on Sunday." The submitter has more info about Iowa State's entry below."Many teams (as well as Iowa State) are using advanced technologies like lithium batteries, near space-grade solar cells, and composite materials such as carbon fiber and fiberglass in their cars. Additionally many of us are utilizing Linux with amateur radio and satellite data phones to monitor weather conditions and to help optimize energy usage.
"We run a LinuxPPC server in our solar car chase vehicle that receives GPS coordinates from a Motorola Encore GPS receiver that is driven by a Lineo uCdimm board running uClinux. The uCdimm board reads in the GPS coordinates and broadcasts the coordinates every second via UDP packets on the ethernet network in the van. The LinuxPPC machine uses the coordinates to track our position and to display upcoming route information (stop lights, turns, road contitions) and to aid our racing strategy. Additionally, the LinuxPPC machine connects to the Internet via a Globalstar satellite phone to periodically download weather maps and forecasts for our current location. We also use GPS and amateur radio with APRS in our other support vehicles to monitor all of our vehicles' positions.
"Most of the code that runs everything is developed in house with C/C++, some of it with the Qt library. Myself and another member of our team will be preparing a detailed presentation in September for our local Unix users group about how we've utilized Linux on our team. If there is interest, I'll post the URL here for that once we've got it prepared.
"A list of other teams competing in ASC next week is available online at the American Solar Challenge web site. Most are university teams from North America, but there are some international teams as well."

Faster
Thanks to Crag Pfeifer for sending a review of James Gleick's Faster. If you've ever felt like life's moving faster then ever, this is worth reading. Faster: The Acceleration of Just About Everything author James Gleick pages 324 publisher Pantheon, 1999 rating 8/10 reviewer Craig Pfeifer (cpfeifer@acm.org,http://www.cpfeifer.org ISBN 0679408371 summary An observation of some of the causes, symptoms and results of living in an accelerated age.Rating: (8/10)
The Scenario Ever feel that the pace of life today is much faster than 10 or 20 years ago? You're not alone. James Gleick offers us 37 insightful observations of the causes, symptoms and results of living in an accelerated age. Interestingly enough, this book is the victim of the condition it describes: out of the 37 chapters, not one of them is more than 12 pages long (7.36 pages on average).If you are looking for high theory about the effects of technology on society and culture, shoot for Marshall McLuhan. If you're wondering who flipped the switch 20 years ago to push western society into overdrive, read on.
What's Bad? Absolutely nothing. The anecdotes hit their mark each time. But don't expect a precise scientific examination of the psycho/sociological effects of technology. Faster is a well-grounded reflection on the current state of society with references to relevant articles and interviews. These reflections do tend to wander slightly off course. For example, you probably didn't expect to receive a history of the major advances in modern elevator technology, in the middle of an explanation of the origin of the 'close door' button. What's Good? Gleick's perspective has the clarity of someone looking in the window of the western world, and the intimacy of a fellow participant. Gleick has a gift for expressing technical subjects with such sensitivity, passion and understanding that the topics and people come alive on the page. This is evident in Gleick's other works, Genius: The Life and Science of Richard Feynman most notably. Also, a wonderful bibliography is provided for further reading.
Summary of Selected Chapters: Pacemaker "Humanity is now a species with one watch and this is it," explains Gleick on his trip to the National Directorate of Time at the Naval Observatory in northwest Washington, DC. In the first chapter, Gleick takes us on a visit to the global metronome that measures time in units so small they pass before you notice they existed. Here devices track the frequencies of atoms and engage 50 other devices around the world in the same conversation millions of times a day: what time is it? We know that a day is 24 hours, 1440 minutes, 86,400 seconds, but the length of a year changes. To account for the subtle wobble of the earth's axis and gradually slowing spin rate, they add a "leap" second whenever it is neccessary to keep everthing in synch. As time goes on, we will have to add this second more and more often.The second half of this chapter is an overview of the 36 upcoming vignettes: Technology enables us to process more information than ever before, but it also allows us to produce more information than ever before. "500 channels" at the click of a button on a remote control, 30 different coffees at the corner coffee franchise. "What is true that we are awash in things, information, in news, in the old rubble and shiny new toys of our complex civilization, and -- strange, perhaps -- stuff means speed."
How Many Hours Do You Work? Juliet Schor calculated that the average American employee spends a full extra month working today compared with similar employees in the 1970's. Based on this, Gleick examines where all of this time went. According to the Bureau of Labor Statistics, payroll records show a stedy decling in weekly hours over the past four decades. But the research is inconclusive: some studies show that we're working more than ever, others show that working hours actually have decreased steadily since the 1950's. This could be due to the fact that the traditional definition of "work time" is changing. Today more people "work from home," spend more time outside of the office thinking about work, spend more time commuting, and take less vacation time than 20 years ago. Why? Gleick posits that time has become a "negative status symbol." If you have "spare time", you must not be very important. How about lunch next week? Let me check my Palm Pilot/Franklin Planner/leather-bound officious looking object that projects to everyone around me that I'm a very busy person... This week is bad, how about in two weeks? "Overwork equals importance." says Gleick. Attention Multitaskers! This chapter (weighing in at a terse 5.5 pages) hits very close to home. One of the biggest contributors to the speed up of life in the western world: multitasking. The simultaneous execution of unrelated activities (flossing and catching up on email) makes us feel more efficient that we shave seconds off of our daily routine, and ensures that we never have to sit idle. New devices have encouraged this habit: cell phones, so we can have meaningful conversations wherever we are, the remote control so we can watch 3 programs all at once, and the ultimate multitasking tool, the computer. Gleick tells us about a Bloomberg employee who is engaged in a phone conversation to a colleague in New York, and simultaneously exchanging e-mail volleys with another colleague in Connecticut. Multitasking is another way we try to do more with our vanishing time, and make sure that every second of our attention is fully utilized. So What's In It For Me? The insights are painfully true, and hit home on multiple levels. The French novelist Stendahl said "a novel is a mirror walking down a road." And that is exactly what purpose this books serves; it is a reflection of the collective choices we have made as a society over the past 20 years, for better or worse. Faster doesn't pass judgement about whether the acceleration that has taken place over the past 20 years is a "good thing" or a "bad thing," it simply points them out and presents the context which allowed them to happen.Purchase this book at ThinkGeek.

Jordan Pollack Answers AI And IP Questions
Professor Pollack put a lot of time and thought into answering your questions, and it shows. What follows is a "deeper than we expected" series of comments about Artificial Intelligence and intellectual property distribution from one of the acknowledged leaders in both fields. How do you justify your expectations? (Score:5, Interesting) by Anonymous Coward For the past 40 years, AI has just been 10 years or so away.It's still just 10 years or so away.
It's not getting any closer.
How do you justify any degree of optimism about the future of AI at this point? What makes now fundamentally different from anytime in the past 40 years?
It is funny, this is the same question I asked Marvin Minsky, the father of AI, at ALife 5 in Japan. He attacked every modern approach, including neural nets, fuzzy logic, evolutionary algorithms, and so on for over an hour, suggesting that his student's (Winston's) thesis should have been the paradigm of the field! I asked, "If AI sucks so much, why are you still in the field after 40 years?"
Hypocrite! Here I am, still in the field after 20 years! As soon as I've convinced myself one approach to AI is too slow, I find another, leaving quietly without attacking the friends I've made. AI is a big wide open field with a lot of smart people trying different things. (Savage attacks by insiders exiting are the worst thing in science, such as Bar Hillel's attack on Machine Translation in the 60's. Forty Years later, MT is "cool" again, in this month's issue of Wired.)
So I can say that, from my perspective as having worked on many different approaches to AI, writing problem space search algorithms for solving puzzles will not result in a general problem solver. Automating predicate logic won't make a computer equivalent to a philosopher. A computer can't do natural language any better than Eliza, without an internal need to communicate to survive and a large blessing of custom hardware. Neural nets are great function approximators with good mathematical results on limited kinds of learning, but we can't set 12 weights to get what we want, let alone 10 billion weights. And even though simple nonlinear systems give off chaos and fractals, Kolmogorov's law tells us simple systems are still simple. Evolution is one path to complexity, but most genetic algorithms simply search a finite search space and optimize a fixed goal.
So I'm locally pessimistic but globally optimistic! Who said AI is 10 years away? It's here now, in limited forms, yielding a lot of economic value, as your mouse clickstream is datamined so the ads which pop up are for things you might actually buy. But the SF ideal of a humanoid robot like Commander Data is centuries away.
I hold the view that any system which responds to its environment in a conditional way based on some internal state, even a thermostat, has a bit of intelligence. Immune systems, ecologies, and economies design things and solve problems. Every computer program you write has a bit of intelligence captured in it. The problem is, real AI of the sort you are alluding to is an organization which might be realizable as a 10 billion line program or a 10 billion weight dynamical neural system, and no human software engineering team can write autonomous code which is more than 10-100 million lines. Even Windows is just DOS with wallpaper, and big applications always require a human in the loop, selecting subprograms from menus or command lines.
Since 1994, we've been working on how to automatically evolve physical symbol systems which would have 10 billion unique moving parts, what we call "Biologically Complex" systems. When I say "We," it is because everything I do is in collaboration with my Ph.D students! A 10 Billion Line program is an absurd goal obviously, but it drives our research to focus in on the process of growth itself, rather than on what shortcuts we can accomplish by hand. We look at co-evolution, which involves machine learners training each other, and on questions of what kinds of substrates for computing could provide a universe of functionality while being constrained in a way which reduces the size or dimensionality of the search space. This constraint is called inductive bias. We seek minimal inductive bias systems, in which the human hints, or "gradient engineering" tricks are fully explicit. (Sevan Ficici, Richard Watson) We still work on neural nets and fractals as a substrate, and have made some progress in understanding how they work (Ofer Melnik, Simon Levy).
It's been more than five years, and while we are not even at the million line mark yet, I am still optimistic and haven't given up on co-evolution to move to a new field. I think that my lab has made progress in understanding why Hillis's sorting networks and Tesauro's Backgammon player were such breakthroughs and where they were limited. (Hugue Juille, Alan Blair). I think we have begun to understand the nature of mediocrity as an attractor in educational systems and how to change the utility functions to avoid collusion, and apply this to human learning (Elizabeth Sklar). We have become more applied, bring co-evolution to the Internet and to robotics, replicating and extending the beautiful results of Karl Sims from 1994 (Pablo Funes, Greg Hornby, Hod Lipson). All the work is available to study at the laboratory's Web site.
AI and ethics. (Score:5, Interesting) by kwsNI What do you say to the people that feel it is unethical to try to create "intelligence"?I take this as a shorter version of the longer religious question the editor thankfully didn't select. I've talked to myrabbi, perhaps one of the great theologians around today. Even though I am an atheist, he thinks I am on a spiritual quest to understand [God as] the principles of the universe which allow self-organization of life as a chemical process far from equilibrium which dissipates energy and creates structure that exploits emergent properties of physics. Can a spiritual quest be unethical? I suggest that people with this question read Three Scientists and Their God, by Robert Wright, or watch the Morris documentary "Fast, Cheap and Out of Control".
A second ethical question, besides usurping God's rights, is how can you take funding from national and military agencies like NSF, Darpa and ONR? For the past 50 years at least, they have been the seed capital for the science behind most of the technological progress I know about. With the venture capital economy, that curiosity-based seed function may be privatized, if some of the big VC funds dedicate 10% for long range science, and the ethical question of whether you are doing something for public good or private gain begins to dominate over the religious and military questions. That is the same question many scientists and Linux hackers ask themselves daily: Can I do good and make money without a conflict of interest?

Frankenstein (Score:5, Interesting) by Borealis For a long time there has been a fear of a Frankenstein being incarnated with AI. Movies like The Matrix and the recent essay by Bill Joy both express worries that AI (in the form of self replicating robots with some AI agenda) can possibly overcome us if we are not careful. Personally I have always considered the idea rather outlandish, but I'm wondering what an actual expert thinks about the idea.Do you believe that there is any foundation for worry? If so, what areas should we concentrate on to be sure to avoid any problems? If not, what are the limiting factors that prevent an "evil" AI?
AI doesn't kill People. AI might make guns smart enough to sense the weight or handsize of the user, preventing children from killing each other. Everything ever invented is capable of good or evil. Evil arises most often when masses of humans are denied fundamental rights. The Evil Rate and Unemployment Rate are closely linked.
I read Bill Joy's article in Wired last month. And I loved the Unabomber's excerpt because it is based on some of the best Philip Dick paranoid Science Fiction, like: Vulcan's Hammer, We Can Build You, and the Simulacrum. There is a lot of SF on the Golem question and one of my favorites is Marge Piercy's He, She, and It , which proposes a moratorium on AI inside humanoid robots. You can have smart software on the Web, and human looking idiobots, but you can't put real AI inside human looking robots, or you have to pay the price.
My lab is indeed working on self-replicating robotics and were worried for a split second about getting the fetal brain tissue reaction when our paper comes out shortly. We can now envision the "third bootstrap", after precision manufacturing and computation, where machines make the machines which make themselves, just as machine tools are used to make more machine tools, and computers compile their own programs. But the replication loop is quite a sophisticated automatic manufacturing process, which requires a large industrial infrastructure, and a lot of liability insurance. So far, no VC's, Saudi Princes, or government agencies have offered the necessary $500M first round of financing for fullyautomateddesign.com.
It would be wrong of me to say leave my frankenbots alone, and go after frankenfoods and frankenano. I think Joe Weizenbaum's book should be required reading, because every few years somebody else comes up with the idea of inserting computers inside animal bodies, so that the first act of any war will be to exterminate all nonhuman life forms. But I do think we have to worry more about large scale industrial and agricultural processes which are allowed to externalize their by-products affecting the environment, than we need worry about robotic ice-9. We will die quicker from e-mail spam caused by viral marketing customer acquisition schemes or from global warming and ozone depletion triggering major climactic change, red tide or another pollutant taking out fish from the food chain, or even from people throwing away old EGA screens and 386 motherboards in landfills, poisoning the aquifers. I promise that for every robot we build, there will be another robot to recycle it when its job is complete.
Anyhow, IMO Joy's angst must reflect the Sun setting on any instruction set architecture besides x86, but that's a different discussion. Talk to me about the ethics, when your very own open source movement leads to the inevitability of an Intel instruction set monopoly by providing a useful alternative to Microsoft :)

Also, how exactly did you get into the field? How did AI intrigue you into what you do now, despite all the controversy to create an intelligence that could possibly be considered a "god" compared to the human existence? Very interesting to say the least, and something I'm interested in.There is no AI business field to speak of which is differentiated from the general software business. Most companies which were "AI companies" in an earlier generation of university spin-offs for Lisp Machines, and Expert Systems Shells, failed miserably. Venture Capitalists won't fall into the same sinkhole twice. There are industrial process control companies which use refined bits of AI, e.g. in visual inspection of manufacturing processes, and Neural Network companies, like HNC, who have changed business plans and are now "pattern-recognition e-commerce security." companies. The Speech recognition industry has condensed into one company. Web- based AI means search engines and Language Engines. Ask Jeeves and Google and Direct Hit and many others may use bits of AI and adaptive technologies in their system.
Jobs in AI are just like software jobs everywhere: chain you to a workstation and make you work out boring details in exchange for salary and very little equity. But find a great graduate program in computer science, and you will likely find fun and exciting work for no salary and no equity! And you have to be great at both real and discrete mathematics as well as a natural born programming genius.
As for me, I started programming computers in APL as a freshman in college, and because it was such a high level language and I didn't sleep much, I wrote an awful lot of code in a few years. I was naturally drawn to building heuristic puzzle solvers, game players, and logical theorem provers. Before I met my wife, friends thought I was in love with computers. After working at IBM, I went to graduate school in Urbana and worked with David Waltz on LISP hacking, natural language processing, and reinvented neural networks, which were censored from the AI curriculum of the early 80's. I came to the limit of what could be done with neural networks for intelligence by 1988, and at Ohio State University, started looking at fractals and chaos as a source for generativity. Unfortunately, interesting behavior requires lots of levels and lots of parameters, which is why we started looking at evolution for selecting and adjusting lots of parameters, a focus since I've been at Brandeis.
While there is a lot of detailed work and dead ends, the search for mechanical intelligence is one of the great unsolved problems, which is in some way deeply equivalent to questions on the origin of life, human language, morphogenesis, child development, and human cultural and economic change. John Casti's book is a great place to start reading about these big problems.
Human brain - AI connection - is there?

Also, what do you think about the potential of the models used today to attempt to achieve a working AI? Do you think that the models themselves (e.g. the neural net model) are correct and have the potential to produce an AI given enough power and configuration, or do you think that our current models are just a stepping stone along the way to a better model which is required for success?
Obviously there are clear medicinal benefits to brain research. And the study of any real biological system leads to interesting metaphors which can be the basis for a novel computational model. But I think it is unlikely that research into the biology of the brain is crucial to understanding cognition or replicating intelligence. It's like studying the width of wires in integrated circuits of a computer. Even if you get the whole wiring diagram for a computer, it still tells you little about the programs running on it. I think understanding the brain is a problem which is underestimated. I heard 25,000 scientists attend the annual Neurosciences meeting, three times the largest ever interested in AI. It could be called the Mandelsciences meeting, and different labs compete to describe what they find in those little windows on the Mandelbrot set! But I have a lot of friends who are neuroscientists, and I can be just as facetious about linguistics.
Seriously, I believe we have to understand and replicate the processes which lead to the development of the brain and its behavior, not replicate the mammalian brain itself.
The second part of your question "how intelligence has emerged in us" can be interpreted as a more interesting direction. Here, there is a lot of opportunity to relate human intelligence as animal intelligence plus a little more. The fields of evolutionary epistemology, adaptive behavior, and computational neuroethology are quite interesting. It is a great question to understand cognition as it appears in other animals, insects, worms, and even bacterial colonies. The basic principles of multicellular cooperation are more important than the millions of specific adaptations of the human brain.
As for models question, it is sort of like asking whether a chair is built out of metal, wood, plastic, rubber, or cardboard. It doesn't matter, as long as it are strong enough. The organization of molecules has to provide a surface and a normal force at the right height for sitting. As for the organization of 10 billion things which might make an AI? Doesn't matter if it is c, java, lisp, neurons, or tightly coupled markovian 2nd order polynomial fuzzy sets. Will it stand, or collapse under its own weight?

We are taking the second path, seeking the principles for self-organization so we can harness them to create and invent forms of organization.. There is a 4th path you don't mention, which is the terminator/Truenames hypothesis, that AI will simply arise among the powerful router machines of the internet.

According to economic theory, utility is what motivates you to make decisions in your own self interest. Simple games, like the prisoner's dilemma, rationalize utility with numeric values to illustrate the concept, but it isn't money at all. If someone behaves in an unpredictable way, we must have our definition of their utility wrong.
There are plenty of motivations for writing open source code, including the challenge and the feeling of altruism, both of which have utility. A lot of people may write open source for credit in the community, which also has utility. If RMS was a radical advocate of anonymity who wrote the GPL so you couldn't put your name on the source code because it promoted the glorification of the individual, participating might provide less utility.

Have you thought about, or to your knowledge has anyone thought about harnessing the power of collective geekdom for sort of a brute force approach to neural networks.

No, its very imaginative. You could be one of my AI grad students. But rather than focusing on neural networks, which, because of matrix multiplication, do not distribute well, people are looking at such systems for evolutionary computation. You can evolve individuals on networked workstations and collect them, or evolve populations which interact occasionally and pass dna around. Look at Tom Ray's Net Tierra project to see how it is going. My colleague Hod Lipson is developing a screensaver for our evolutionary robotics project, but release 1 will be Windows rather than Linux compatible (./sorry)
Actually, one of my early business plans for the Internet, circa the first working java browsers, was to show naughty pictures while harvesting cycles from your computer and reselling them to people needing computer time. All was needed was an assembly language interpreter in java and some interfacing. The problem is that most computationally intense problems people want to solve have large data flow requirements which conflict with the download of the naughty pictures! When I recently tried to corner the market in pig latin domain names for my new "incubator", panies.com panies.com, I didn't secure putation.com because it sounded bad.

However, there is a critical piece missing from all these visions. intelligence is a property of an organization of computation, it is not computation itself. The problem of robotics is not the limited power of microcomputers, since we could drive any robot from a supercomputer if we knew what to write! We can get infinite cycles already, but nobody can write a coherent program bigger than 10M lines. We have figure out to use cycles towards discovery of a process of self-organization, rather than on a known software organization itself.
AI Metrics (Score:5, Interesting) by john_many_jars I have read several coffee table science books on the subject and often find myself asking for a way to measure AI. As has been noted, AI is always elusive and is just around the corner. My question is how do you gauge how far AI has come and what is AI?For instance, what's the difference between your TRON demonstration and a highly advanced system of solving a (very specific) non-linear differential equation to find relative and (hopefully absolute) extrema in the wildly complicated space of TRON strategies? Or, is that the definition of intelligence?
This is a very hard question which I won't be able to joke my way out of. I think that system performance in specific domains can be measured, like a rating system for a game likeTRON. I think we might be able to get a measure of the generative capacity of a system in all possible environments, by capturing strings of symbols representing different actions, and looking at the grammar of behavior. In general, however, observers have an effect on their observations of computational capacity. I usually think of intelligence as a measurement, not the thing being measured, sort of like the difference between temperature and heat, or weight and mass. It could be a measurement of operational knowledge (programmed, not static in a database), or of efficient use of knowledge resources. This measurement is applied to an organization. So committees of very smart people can operate idiotically, and groups of dumb insects can be very intelligent.
My current best working definition is that intelligence is the ratio of the amount of problem-solving accomplished to the number of cycles wasted. When I say we need 10B lines of code, it is not to say that raw program size is a measure of intelligence, but to express the idea that inside that code are enough different heuristics and gizmos to solve lots of problems effectively.

Once secure distribution of programs on a rental basis is established, all content publishing will move inexorably into that mode to maximize profits. No more books, no more records. No more ownership. Dispossession.

The history and future of money is very interesting, and one you can read about in various books, including one byMilton Friedman, and one from the Cato Institute. I think today's software houses who force upgrades on their customers are like the wildcat banks of the nineteenth century, printing up banknotes, and then declaring bankruptcy, vanishing with the deposits and setting up shop in another town.
Before money, there was simply trade in raw and polished goods. Then there was weighing and coinage. Lots of people thought coins were the real value and heartily resisted paper money. The gold and silver standards gave way, and eventually the idea that there was gold for every dollar bill was revealed as a hoax, and now "money" is simply a record in your bank's computer that there is a certain amount you are entitled to withdraw based on the amounts other banks have deposited for you. The only essential different between a rich and poor person is what the bank computers and the registrar of deeds say it is, backed by military force. And the money supply and international exchanges now somehow represents our national wealth with respect to other nations, and other nation's confidence that our banking system isn't duplicating dollars. Instead of objects of trade, money is information about potential trade.
While you might not like the idea that money is abstract and in limited supply, and you have more or less than you want, it is the soft underbelly of "Starship Economics" that Gene Roddenberry died before coming up with the backstory for how to have a non-mediocre society with unlimited replication for all.
I once invented a transporter machine for paper using public key crypto and fax technology. It would hold the source paper in a metal box, verify the copy was printed, and then destroy the original and legitimize the copy. With this system, you could fax a dollar bill to a friend! Now: is a dollar bill is just the likeness of a dollar bill on a crinkly piece of thermal paper, or the actual piece of green stuff? If Paypal can figure out how you can beam money from your palmpilot to mine, but a bug lets you keep a copy of the money, I bet their valuation would go way down.
I am simply saying that permanent use and resale licenses to changeable information (software, art, literature, music, movies) which can be traded securely, without loss or duplication, in a public market, is a form of currency.
Unlimited replication of currency just doesn't work, any more than two copies of William Shatner.
I stake the middle ground. Both the "right" copyright publishers who make currency loss through expiring keys and forced upgrades, and the "left" copyright violators who duplicate currency, will be welcome at my table when they see the light.
