World's Hardest Sudoku 179

jones_supa writes "A Finnish PhD in mathematics, Arto Inkala, has allegedly created the world's toughest sudoku puzzle. 'There's no straightforward way to define the difficulty level of a sudoku. I myself doubt if this is the hardest in the world, but definitely harder than my previous ones,' Inkala sets off humbly. The news agencies around Europe are nonetheless excited (Google translation of Finnish original). The particular difficulty in this version lies in the number of deductions you have to make in order to fill in a single number on the grid. 'It is a common misconception that the less initial numbers, the harder the puzzle. The most challenging ones have 21-25', the creator adds."

Headlights That See Through Rain and Snow 210

wisebabo writes "I think it was Newton who said if you knew the position and velocity of every particle in the universe, you could predict the future down to the effect the flutter of a sparrow's wing would have on the weather. Aside from quantum indeterminacy (which, of course, he knew nothing about) and questions of free will, it is clear we are a long long way from getting even close to the theoretical limits of prediction. Still, here's something that, to me, is very impressive. Some researchers manage to track raindrops (or snowflakes) in front of a light and, in real time, change the beam so that they are not illuminated! This drastically reduces glare. The obvious application is for driving cars in inclement weather. I'm hoping we're entering a new age where computers (and cheap sensors) have become so powerful as to make possible a whole host of 'magical' (like Arthur C. Clarke predicted) applications."

EU Parliament Adopts eCall Resolution 212

arisvega writes with news that the European Parliament has pass a resolution in support of eCall, an initiative to install devices in vehicles that automatically contact emergency services in the event of a crash. The resolution calls on the European Condition to make it mandatory for all new cars starting in 2015. "The in-vehicle eCall system uses 112 emergency call technology to alert the emergency services automatically to the location of serious road accidents. This should save lives and reduce the severity of injuries by enabling qualified and equipped paramedics to get to the scene within the first “golden hour” of the accident, says the resolution. The eCall system could save up to 2,500 lives a year and reduce injury severity by 10 to 15%, it adds."

Open Source Morrowind Version 0.16.0 Released 98

An anonymous reader writes "The OpenMW team recently released a new version of their open source engine. While the project is not fully playable yet, the goal is to preserve Morrowind, provide modders a better engine and tool kit for creating their works, and make it cross-platform. Like most open source projects, they are always seeking new contributors. So, what do you think; what's the state of FLOSS games that are not first-person shooters?"

Google Killing Off Mini, Video, and iGoogle 329

New submitter Trashcan Romeo writes "Three years ago, it accounted for 20% of all visits to Google's home page. Two years ago, Lifehacker readers voted it the best start-page service. Today it was announced that iGoogle will be retired — or in the company's parlance, 'spring cleaned' — on November 1, 2013." Google Video is also getting the axe this summer. It hasn't accepted new videos since 2009, and all of the old ones will be migrated to YouTube. The company is also getting rid of Google Mini, Talk Chatback, and their Symbian search app.

Bill Gates: the Traditional PC Is Changing 552

Billly Gates writes "Bill Gates, in an interview with Charlie Rose last night, defended the move to Metro-ize Windows 8 and focus solely on the tablet experience (here's the video — tablet talk starts around 28 minutes in). When asked how traditional PC users will react, he explained that the world is moving into tablets, and a new PC needs to have both experiences integrated together. Also, he defended the move to build the Surface while charging his competitors a bundle for Windows 8. He says users have access to both experiences, whether it is a signature Microsoft one, or from an OEM. Is the a sign the desktop is dead or dying?" Gates stopped short of saying the traditional PC is dead, but dodged direct questions about its future. This is a big change to the stance he has advocated in years past.

SETI Running Out of Money 312

New submitter opusman writes "According to an Australian space analyst, SETI is running out of money. Despite needing only $2 million a year, a relatively small amount in space industry terms, they are facing a financial crisis. From the article: 'Getting on board a spacecraft is tricky. There are few places for professional astronauts. Even when Richard Branson and a group of other visionaries makes space tourism more affordable, it will still cost huge sums to fly. But getting a foothold in the greatest quest of all can be done for just a few tens of donated dollars. Which is why it beggars belief that the SETI quest is on its knees.'"

Google Proposes Fighting Piracy By Blocking Ad Money 202

judgecorp writes "Google has published a report, written by the Performing Rights Society and BAE Detica, which says the way to fight piracy is not to chase the sharers, but to cut off the money in the system. 'Some 86% of advertising on the pirate sites surveyed by Detica comes from networks that have failed to sign up with the UK’s self-regulatory bodies or commit to strong codes of conduct. More than two thirds of the sites that rely on subscriptions or payments display well-known credit card logos. Online advertisers should be encouraged to sign up to self-regulatory codes of conduct. Credit card and online payment facilities, the pirate’s oxygen supply, must be blocked.'But is Google absolutely sure it isn't doing that with AdSense?"

RIM CEO: 'There's Nothing Wrong With the Company' 230

redletterdave writes "Research In Motion is in trouble. The BlackBerry maker has been suffering from an identity crisis for the last six months, which has resulted in mass layoffs, lots of job shuffling, dramatic drop-offs in market share and a quickly decaying portfolio for investors. But not according to Thorsten Heins! The newly-appointed CEO published an op-ed in the Toronto Globe and Mail on Tuesday, and also appeared on a radio program the same morning, to deliver one message: 'There's nothing wrong with the company as it exists right now.'"

Facebook API Bug Deletes Contact Info On Phones 178

An anonymous reader writes "If you thought that Facebook's recent unannounced change of its users' email address tied with their account to Facebook ones was bad, you'll be livid if you check your mobile phone contacts and discover that the change has deleted the email addresses of many of your friends. According to Facebook, the glitch was due to a bug in its application-programming interface, and causes the last added email address to be pulled and added to the user's phone Contacts. The company says they are working hard at fixing the problem, but in the meantime, a lot of users have effectively lost some of the information stored on their devices."

Sea Level Rise Can't Be Stopped 521

riverat1 writes "Sea level rise won't stop for several hundred years even if we reverse global warming, according to a study published in the journal Nature Climate Change. As warmer water is mixed down into the oceans, it causes thermal expansion of the water. Under the best emissions scenario, the expected rise is 14.2 cm by 2100; under the worst, 32.2 cm from thermal expansion alone. Any water pumped from aquifers or glacial/ice sheet melt is added to that."

Ford Predicts Self-Driving, Traffic-Reducing Cars By 2017 388

An anonymous reader tips a story about comments from Ford Motor Company showing how confident they are in the autonomous car technology currently in development. They say self-driving cars will be here within just five years, and that the tech to do so is available already. They also think these cars will dramatically affect the flow of traffic. Quoting: "Ford makes this projection, based on simulator studies: If one in four cars has Traffic Jam Assist or similar self-driving technologies, travel times are reduced by 37.5% and delays are reduced by 20%. In other words, if the freeway part of your rush hour commute takes 60 minutes, it will drop to 38. That’s because adaptive cruise control (ACC) is better at pacing the car ahead without continual brake, speed-up, brake cycles. Here’s how it works: Stop-and-go ACC keeps pace with the car ahead, using a look-ahead radar and mirror-mounted camera. Lane keep assist keeps the car centered, also taking advantage of the camera in the mirror. Electric power steering is better for remote control than mechanical power steering; it can be guided by the Traffic Jam Assist black box. Sonar units — for blind spot detection and cross traffic alerts (cars crossing behind when backing) — monitor traffic to the side. Combine all those and you have a car that’s smart enough to guide itself during predictable, low-speed conditions."

Microsoft Writes Off $6.2 Billion From aQuantive Acquisition 115

An anonymous reader writes "Microsoft had high hopes for aQuantive when it paid $6.3 billion to acquire the combo online marketing services vendor/advertising agency in 2007, evidently in response to Google's acquisition of DoubleClick. 'Microsoft is intensely committed to creating a thriving advertising business and to partnering closely with all key constituencies in this industry to help maximize the digital advertising opportunity for all,' declared CEO Steve Ballmer. Yesterday Microsoft wrote off $6.2 billion of its investment in aQuantive, as its online division continues to struggle. MS-watcher Mary Jo Foley points out this is one in a list of bad purchases from Microsoft. On the bright side, Microsoft managed to recover an estimated $500 million three years ago from the deal when it sold off the Razorfish ad agency (not sure why this amount wasn't subtracted from today's writedown)."
Security

Choosing the Right Security Tools To Protect VMs 44

Nerval's Lobster writes "Tech writer David Strom starts a discussion about how you should go about securing virtual machines for your organization. 'The need to protect physical infrastructure is well known at this point: most enterprises would balk at a network without any firewalls, intrusion prevention devices or anti-virus scanners. Yet these devices aren’t as well deployed in the virtual context. ... Take firewalls, for example. The traditional firewalls from Checkpoint or Juniper aren’t designed to inspect and filter the vast amount of traffic originating from a hypervisor running, say, ten virtualized servers. Because VMs can start, stop, and move from hypervisor to hypervisor at the click of a button, protective features have to be able to handle these movements and activities with ease and not set off all sorts of alarms within an IT department.' He goes through the main functional areas that need protection, and points out that many vendors make it difficult to price out a given security plan."

'Rubber-Band Electronics' Can Stretch To 200 Percent Their Original Size 37

Zothecula writes "In the quest to develop implantable electronics to monitor the human body from within, flexibility and stretchability have been major hurdles. We've seen numerous developments including stretchable LED arrays, an implantable device for measuring the heart's electrical output, and an electrode array that melts onto the surface of the brain. Now researchers have developed technology that combines a porous polymer and liquid metal that allows electronics to bend and stretch to more than 200 percent their original size (abstract)."
