Submission + - Electromagnetic weapons that destroy electronics, ( 2

PolygamousRanchKid writes: The wars of the 21st will be dominated by ray guns. That, at least, is the vision of a band of military technologists who are building weapons that work by zapping the enemy's electronics, rather than blowing him to bits.

America's air force is developing a range of them based on a type of radar called an active electronically scanned array (AESA). When acting as a normal radar, an AESA broadcasts its microwaves over a wide area. At the touch of a button, however, all of its energy can be focused onto a single point. If that point coincides with an incoming missile or aircraft, the target's electronics will be zapped. BAE Systems, a British defence firm, is building a ship-mounted electromagnetic gun. The High-Powered Microwave, as it is called, is reported by Aviation Week to be powerful enough to disable all of the motors in a swarm of up to 30 speedboats.Disabling communications and destroying missiles is one thing. Using heat-rays on the enemy might look bad in the newspapers, and put civilians off their breakfast.

To every action there is, of course, an equal and opposite reaction, and researchers are just as busy designing ways of foiling electromagnetic weapons as they are developing them.

Richard Stallman's Dissenting View of Steve Jobs 1452

Garabito writes "Richard Stallman, founder of the Free Software Foundation, has posted his not-so-fond memories of Steve Jobs on his personal site, saying, 'As Chicago Mayor Harold Washington said of the corrupt former Mayor Daley, "I'm not glad he's dead, but I'm glad he's gone." Nobody deserves to have to die — not Jobs, not Mr. Bill, not even people guilty of bigger evils than theirs. But we all deserve the end of Jobs' malign influence on people's computing.' His statement has spurred reaction from the community; some even asking to the Free Software movement to find a new voice."

Graphene 'Big Mac' — One Step Closer To Microchips 50

RogerRoast writes "Scientists at the University of Manchester have come one step closer to creating the next generation of computer chips using graphene. By sandwiching two sheets of graphene with another two-dimensional material, boron nitrate, the team created the graphene 'Big Mac' – a four-layered structure which could be the key to replacing the silicon chip in computers. The research results were published in Nature Physics (abstract; full version paywalled)."

.NET Programmers In Demand, Despite MS Moves To Metro 319

mikejuk writes "Are you a newbie programmer looking for a job? It seems your best bet is to opt for .NET. According to technical jobs website, companies in the U.S. have posted more than 10,000 positions requesting .NET experience — a 25 percent increase compared to last year's .NET job count. So Microsoft may want us to move on to Metro but the rest of the world seems to want to stay with .NET."

Ask Slashdot: Create Custom Recovery Partitions With FOSS? 133

First time accepted submitter KowboyKrash writes "OK, a little background: I use Acronis to create custom recovery partitions for my personal computers that include all my software and drivers. I also work for a growing computer repair shop which has ventured into eBay sales of refurbished computers. We receive the machines with wiped hard drives. Since we get multiples of each model, we load everything on one then make images with Clonezilla. It would be nice to set up recovery partitions as well. Acronis is out of the question, since it would cost for a license for each machine. Do any Slashdotters know of any FOSS options?"

Comment communism... (Score 1) 193

Don't be too rush to state that the Soviet model is flawed enough to be impractical. Most of the communism's flaws were from the way information and intelligence was handled, and for that matter pure capitalism doesn't really cut it either. I think neither freedom, nor dictatorship can, as core postulates, solve problems and sustain (business)systems when you discuss ways to make money, because even if you aggressively centralise planning and logistics, or aggressively decentralise all management people can not properly optimise and perform efficiently at work, no matter how you regulate information and intelligence. i believe that an organic approach based on fairness and well planned renewability as an ideology should be a good direction both in politics and business, and this type of policy can assure well regulated and efficient workflow. This "free-market" you are talking about allow simultaneous existence of both cvasi-anarchic FOSS and cvasi-dictatorial corporative environments. They both have huge advantages and disadvantages, so really you cannot (using curent ideologies, that is) praise, nor condemn Nokia's recent choices in business. They want better penetration of american markets and a powerful platform available fast that can comply with their intelectual property policies. That's what Symbian was before they open sourced it for lack of developer traction. They started toying with Maemo and later MeeGo in order to replace it, only to bump into the same policy problem that made development slow, and later to not consider Android as platform. They wanted to control their property better and still make money. Now they don't really need Qt, they'll sell it, it's users are almost used to it, as it happened before, and also FOSS world has plenty examples, so there won't be that much trouble. Notice how freedom to own and freedom to share can't mix up properly here. This is a giant deja-vu and proper renewable business model have both as an obstacle. Lack of choices versus lack of moderation. --- imma probably make smartphone apps based on ruby and GTK and someday people will buy it, if I do a fair job....

Submission + - Is it Fair to Criticize Canonical and Ubuntu for G ( 1

Thinkcloud writes: As Ubuntu focuses more on usability, it is developing a OS that is not as geeky as the rest of the Linux distros and that makes it the most popular Linux distro, among both geeks and non-geeks. However at the same time trends like more in-house development than any other Linux distros and going for commercial models starting to make the Canonical chief Mark Shuttleworth look like a renegade autocrat in the FOSS community. Why should we care?

Comment What can nVidia do? (Score 1) 195

Well nVidia can't really quit developing graphic card drivers and promoting the Windows platform... I mean FOSS users would like seeing nVidia giving more attention to linux and the other *nix-es, and also getting back at Microsoft by moving to OSX should still benefit FOSS, at least in a way. But as long as there are Microsoft technologies such as DirectX and Direct3D in the middle, PC Gaming will more or less be a Windows asset, without Microsoft backing anything...
