86 years ago, 1931. Thomas Edison: "I'd put my money on the sun and solar energy. What a source of power!"
In 1931, not long before he died, the inventor told his friends Henry Ford and Harvey Firestone: I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.
Infinite Star of 1,241,100,000,000 never-repeating π fell upon Earth in ancient times and delivers Einstein on 3.14
π is commonly defined as the ratio of a circle's circumference C to its diameter d : pi = C/d
The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi" .
The ratio C/d is constant, regardless of the circle's size. For example, if a circle has twice the diameter of another circle it will also have twice the circumference, preserving the ratio C/d. This definition of p implicitly makes use of flat (Euclidean) geometry; although the notion of a circle can be extended to any curved (non-Euclidean) geometry, these new circles will no longer satisfy the formula p = C/d.

Outbluffed: Machine beats humans first time in poker, the last remaining game where humans had managed to maintain upper hand
Libratus, an AI built by Carnegie Mellon University racked up over $1.7 million worth of chips against four of the top professional poker players in the world in a 20-day marathon poker tournament that ended on Tuesday in Philadelphia.
While machines have beaten humans over the last two decade in chess, checkers, and most recently in the ancient game of Go, Libratus' victory is significant because poker is an imperfect information game - similar to the real world where not all problems are laid out and the difficulty in figuring out human behaviour is one of the main reasons why it was considered immune to machines.
One of the main reasons for Libratus' victory was the machine's ability outbluff humans.
"The computer can't win at poker if it can't bluff," said Frank Pfenning, head of the Computer Science Department at CMU.
"Developing an AI that can do that successfully is a tremendous step forward scientifically and has numerous applications. Imagine that your smartphone will someday be able to negotiate the best price on a new car for you. That's just the beginning."
Dong Kim, one of the four top poker players who participated in the tournament echoed the statement. The 28-year old, originally from Seattle, had also participated in a similar poker tournament with another AI machine built by CMU in 2015 named Claudico.
"It was about half way through the challenge (with Libratus when) I knew we wouldn't come back," said Kim. read more »
Digital. Trump rarely uses email: "no computer is safe". Hack self-driving cars' sensors? $43 & a laser pointer
Jan. 01, 2014
PALM BEACH, Fla. President-elect Donald Trump says that "no computer is safe" when it comes to keeping information private, expressing new skepticism about the security of online communications his administration is likely to use for everything from day-to-day planning to international relations.
Trump rarely uses email or computers, despite his frequent tweeting.
"You know, if you have something really important, write it out and have it delivered by courier, the old-fashioned way. Because I'll tell you what: No computer is safe," Trump told reporters during his annual New Year's Eve bash. "I don't care what they say."
"Anybody can go online and get access to this, buy it really quickly, and just assemble it, and there you go, you have a device that can spoof lidar," Petit, a cybersecurity expert, told Business Insider.
One of the first researchers to show how easy it is to hack self-driving cars' sensors, he was able to trick a sensor into thinking objects were there when they weren't, and vice versa. read more »

open a bank account in just 8 minutes? you can lose it even faster - smartphone-only bank N26 German fintech company N26, which made its name mocking traditional banks, has found itself on the receiving end of criticism after a security researcher proved its smartphone apps exposed users to potential account hijacking.
N26, previously known as Number26, has expanded rapidly since it launched in early 2015 as a smartphone-only bank with no local branches, with the backing of major global investors including Silicon Valley's Peter Thiel.
Vincent Haupert, a research fellow and PhD student in the computer science department of the University of Erlangen-Nuernberg, told the Chaos Communications Congress in Hamburg how he and two colleagues found N26 security defenses riddled with holes that could have been used to defraud thousands of users.
"They say you can open a bank account in just eight minutes," Haupert said. "As it turns out, you can lose it even faster." In a statement, N26 thanked Haupert for alerting the company to "a theoretical security vulnerability" and advising it on fixes, which N26 said it completed this month.
N26 offers a range of online banking and other financial services to 200,000 customers in 17 European countries through a banking license granted earlier this year by German financial regulator Bafin. N26 executives have been the most outspoken among new fintech players in arguing traditional banks are failing to serve customers more directly by relying on antiquated local branch relationships instead of modern, phone-based services.
"I don't see banks at all as my competitors. They just can't move fast enough," N26 Chief Executive Valentin Stalf told Reuters last year. read more »

In seconds: How fast driver able to switch from relaxation to control driverless car when machine is unsure to make decisions
Brown was passionate about his driverless car which was speeding into truck trailer and killed its master
Washington: Joshua Brown, 40, a former Navy SEAL is the first person to die at the wheel of his confidently-trusted self-driving car. His computer-guided Tesla Model S hit a tractor trailer on a freeway in Williston, Florida, in May.
And here's what the Model S owner's manual has to say about Autopilot: "...Always drive attentively and be prepared to take immediate action." (Note: How fast can you switch yourself from relax mode into controlling the wheel to avoid a fatal accident?)
