Forget 6-Minute Abs: Learn To Code In a Day 306

whyloginwhysubscribe writes "The usually excellent BBC 'Click' programme has an article on 'Why computer code is the new language to learn' — which features a company in London who offer courses on learning to code in a day. The BBC clip has an interesting interview with a marketing director who, it seems to me, is going to go back and tell his programmers to speed up because otherwise he could do it himself! Decoded.co's testimonials page is particularly funny: 'I really feel like I could talk credibly to a coder, given we can now actually speak the same language.'"

Submission + - Quantum Cryptography Theory Has A Security Defect (net-security.org)

An anonymous reader writes: Researchers at Tamagawa University, Quantum ICT Research Institute, announced today that they had proved the incompleteness and limit of the security theory in quantum key distribution. They showed that the present theory cannot guarantee unconditional security. Until now, the majority of researchers in quantum information science have believed that quantum cryptography (quantum key distribution) can provide unconditional security. The guarantee of its unconditional security is given by the trace distance, which is a quantum version of the evaluation of a mathematical cipher. However, since 2006, new developments in the field have cast criticism over the meaningful security of cryptography ensured only by the trace distance. Despite these criticisms, many papers have continued to claim that the trace distance guarantees unconditional security in quantum key distribution.

Finding Fault With Anti-Fracking Science Claims 505

A widely carried Associated Press article (here, as run by the Wall Street Journal) reports that some of the convincingly scientific-sounding claims of opponents of fracking don't seem to hold up to scrutiny. That's not to say that all is peaches: the article notes, for instance, that much of the naturally radioactive deep water called flowback forced up along with fracking-extracted gas "was once being discharged into municipal sewage treatment plants and then rivers in Pennsylvania," leading to concern about pollution of public water supplies. Public scrutiny and regulation mean that's no longer true. But specific claims about cancer rates, and broader ones about air pollution or other ills, are not as objective as they might appear to be, according to Duke professor Avner Vengosh and others. An excerpt: "One expert said there's an actual psychological process at work that sometimes blinds people to science, on the fracking debate and many others. 'You can literally put facts in front of people, and they will just ignore them,' said Mark Lubell, the director of the Center for Environmental Policy and Behavior at the University of California, Davis. Lubell said the situation, which happens on both sides of a debate, is called 'motivated reasoning.' Rational people insist on believing things that aren't true, in part because of feedback from other people who share their views, he said."

Submission + - Kodak loses patent case vs. Apple, RIM; plans appeal (blogspot.ca)

quantr writes: ""Eastman Kodak Co has lost an appeal of a patent dispute over digital image preview technology with Apple Inc and Research In Motion Ltd, which could set back the onetime photography giant's efforts to raise money in bankruptcy by selling patents.

The U.S. International Trade Commission on Friday upheld a May 21 ruling by Judge Thomas Pender of that agency that neither Apple nor RIM had violated Kodak's rights in the so-called '218 patent, which covers how digital cameras preview images.
"The investigation is thus terminated," the agency said.
Kodak has been hoping to recover $1 billion, and said on Sunday it plans an appeal to the U.S. Court of Appeals for the Federal Circuit in Washington, D.C.
"The validity of the '218 patent has been upheld in previous litigation at the ITC and was affirmed by the U.S. Patent and Trade Office in the face of two separate challenges," it said. "We are confident that its validity will ultimately be upheld."
Kodak filed for Chapter 11 bankruptcy protection from creditors on January 19. Patent litigation has in recent years been a major part of the Rochester, New York-based company's strategy to generate revenue.""

12 Ways LibreOffice Writer Tops MS Word 642

Open source office software is has gotten pretty good over the past decade or so; I got through grad school with OpenOffice (now known as LibreOfifice), and in my estimation was no worse off when it came to exchanging files with classmates than were friends with different versions of Word. Now, reader dgharmon writes "Writer has at least twelve major advantages over Word. Together, these advantages not only suggest a very different design philosophy from Word, but also demonstrate that, from the perspective of an expert user, Writer is the superior tool."

Macbook Owner With Defective GPU Beats Apple In Court 280

New submitter RockoW writes "A few years ago, Apple sold defective computers of the MacBook Pro line. They had the defective Nvidia 8600M GT GPU. In this case Apple refused to take the computer back and issue me a refund. Instead, they promised to replace the 8600M GT boards when they failed, up to four years from the date of purchase. Three years later, the MacBook Pro failed and they refused to replace it. This guy took them to the court and won by their own means."

Police Forensics Team Salvage Blind Authors' Inkless Novel Pages 100

Blind author Trish Vickers wrote 26 pages of her novel's first chapter when her son noticed she was writing without ink. Her manuscript was saved however after they took it to the Dorset Police department. A forensic team there worked on it in their spare time, and after 5 months they were able to recover the lost pages. Vickers said: “I think they used a combination of various lights at different angles to see if they could get the impression made by my pen. I am so happy, pleased and grateful. It was really nice of them and I want to thank them for helping me out.”

Artificial Neural Networks Demonstrate the Evolution of Human Intelligence 107

samazon writes "Ph.D. students at Trinity College in Dublin have constructed an artificial neural network model to demonstrate the Machiavellian intelligence theory — that human intelligence evolved based on the need for social teamwork and indexing a variety of social relationships and statuses. (Abstract) The experiment involved programming a base group of 50 simulated 'brains' which were required to participate one of two classical game theory dilemmas — the Prisoner's Dilemma or the Snowdrift game. Upon completion of either game, each 'brain' produced 'offspring' asexually, with 'brains' that made more advantageous choices during the games programmed to have a better chance to reproduce. A potential random mutation during each generation changed the 'brain's structure, number of neurons, or the strengths of the connections between those neurons,' simulating the evolution of the social brain. After 50,000 generations, the model showed that as cooperation increased, so did the intelligence of the programmed brains." The full paper is available.

US CompSci Enrollment Up For 4th Year Running 101

dcblogs writes "Interest in computer science continues to grow among undergrad students, who pushed enrollments up nearly 10% in the 2011-12 academic year, according to the Computing Research Association (CRA) of enrollment and graduation rates at Ph.D.-granting universities. This marks the fourth straight year of increases. Enrollments might have been even higher if not for enrollment caps at some schools that don't have enough faculty, equipment or classrooms to meet demand. Enrollments increased 10% last year as well, but overall enrollments remain below the peak reached during the dot.com bubble. Around 2002, each school had a department with an average enrollment of about 400 students; by 2006-07, that enrollment average had declined to about 200. Average enrollments per department are now nearing 300, according to the survey."

Inside the World's Largest LAN Party 199

MrSeb writes "Last weekend, over 12,000 LAN party goers turned up at DreamHack Winter 2011 in Jonkoping, Sweden with a PC under the arm, on their back, or packed carefully in the trunk of their car. Every single attendee is squeezed into just three massive halls — the largest holding 5,000 computers — or four days, only taking brief breaks to sleep or check out one of the many stages (including some of the largest e-sport tournaments of the year). Being the largest LAN party in the world, DreamHack's infrastructure is suitably monumental: it takes days to lay the thousands of cables, and at the heart of the network is tower of Cisco routers that interface with a 120Gbps internet connection provided by Telia."
