In a Self-Driving Future, We May Not Even Want To Own Cars

Sun, 23 Nov 2014 13:23:00

HughPickens.com writes: Jerry Hirsch writes in the LA Times that personal transportation is on the cusp of its greatest transformation since the advent of the internal combustion engine. For a century, cars have been symbols of freedom and status. But according to Hirsch, passengers of the future may well view vehicles as just another form of public transportation, to be purchased by the trip or in a subscription. Buying sexy, fast cars for garages could evolve into buying seat-miles in appliance-like pods, piloted by robots, parked in public stalls. "There will come a time when driving the car is like riding the horse," says futurist Peter Schwartz. "Some people will still like to do it, but most of us won't." People still will want to own vehicles for various needs, says James Lentz, chief executive of Toyota's North American operations. They might live in a rural area and travel long distances daily. They might have a big family to haul around. They might own a business that requires transporting supplies. "You will still have people who have the passion for driving the cars and feeling the road," says Lentz. "There may be times when they want the cars to drive them, but they won't be buying autonomous-only cars." One vision of the future is already playing out in Grenoble, France, where residents can rent from a fleet of 70 pod-like Toyota i-Road and Coms electric cars for short city trips. "It is a sharing program like what you see in Portland with bicycles," says Lentz. Drivers can check out and return the cars at various charging points. Through a subscription, they pay the equivalent of $3.75 for 30 minutes. Because the vehicles are so small, its easy to build out their parking and charging infrastructure. Skeptics should consider the cynicism that greeted the horseless carriage more than a century ago, says Adam Jonas. He adds that fully autonomous vehicles will be here far sooner than the market thinks (PDF). Then, Jonas says, skeptics asked: "Why would any rational person want to replace the assuredness of that hot horse body trustily pulling your comfortable carriage with an unreliable, oil-spurting heap of gears, belts and chains?"

How "Big Ideas" Are Actually Hurting International Development

Sun, 23 Nov 2014 10:10:00

schnell writes: The New Republic is running a fascinating article that analyzes the changing state of foreign development. Tech entrepreneurs and celebrities are increasingly realizing the inefficiencies of the old charitable NGO-based model of foreign aid, and shifting their support to "disruptive" new ideas that have been demonstrated in small experiments to deliver disproportionately beneficial results. But multiple studies now show that "game changing" ideas that prove revolutionary in limited studies fail to prove effective at scale, and are limited by a simple and disappointing fact: no matter how revolutionary your idea is, whether it works or not is wholly dependent on 1.) the local culture and circumstances, and 2.) who is implementing the program.

Great Firewall of China Blocks Edgecast CDN, Thousands of Websites Affected

Sun, 23 Nov 2014 07:01:00

An anonymous reader writes: Starting about a week ago, The Great Firewall of China began blocking the Edgecast CDN. This was spurred by Great Fire's Collateral Freedom project, which used CDNs to get around censorship of individual domains. It left China with either letting go of censorship, or breaking significant chunks of the Internet for their population. China chose to do the latter, and now many websites are no longer functional for Chinese users. I just helped a friend diagnose this problem with his company's site, so it's likely many people are still just starting to discover what's happened and the economic impact is yet to be fully realized. Hopefully pressure on China will reverse the decision.

Judge Unseals 500+ Stingray Records

Sun, 23 Nov 2014 04:03:00

An anonymous reader sends this excerpt from Ars Technica: A judge in Charlotte, North Carolina, has unsealed a set of 529 court documents in hundreds of criminal cases detailing the use of a stingray, or cell-site simulator, by local police. This move, which took place earlier this week, marks a rare example of a court opening up a vast trove of applications made by police to a judge, who authorized each use of the powerful and potentially invasive device According to the Charlotte Observer, the records seem to suggest that judges likely did not fully understand what they were authorizing. Law enforcement agencies nationwide have taken extraordinary steps to preserve stingray secrecy. As recently as this week, prosecutors in a Baltimore robbery case dropped key evidence that stemmed from stingray use rather than fully disclose how the device was used.

Samsung Seeking To Block Nvidia Chips From US Market

Sun, 23 Nov 2014 00:05:00

An anonymous reader writes: Bloomberg reports that Samsung has filed a complaint with the U.S. International Trade Commission asking them to block the import of Nvidia's graphics chips . This is part of Samsung's retaliation for a similar claim filed by Nvidia against Samsung and Qualcomm back in September. Both companies are wielding patents pertaining to the improved operation of graphics chips in cell phones and other mobile devices.
