How IBM Is Making Your Passwords Useless
For years, quantum computing has been hailed as a technology that could change the way the modern world works, but a long-standing technical issue has kept that potential from being realized. Now, in a paper published in the journal Nature last week, IBM scientists have taken a big step (see how I avoided the temptation to make a pun there?) toward solving that problem — and while it could represent progress toward making quatum computers real, it also could mean that current cybersecurity standards will soon be much easier to crack. In other words, your passwords could be obsolete soon.
The power of quantum computing has some obvious appeal: The increase in processing power could speed up research, especially in big data applications. Problems with large datasets, or those that need many millions (or billions, or more) of simulations to develop a working theory, would be able to be run at speeds unthinkable today. This could mean giant leaps forward in medical research, where enhanced simulations can be used to test cancer treatments or work on the development of new vaccines for ebola, HIV, malaria and the other diseases. High-level physics labs like CERN could use the extra power to increase our understanding of the way the universe at large works.
But the most immediate impact for the regular person would be in the way your private information is kept safe. Current encryption relies on massively large prime numbers to encode your sensitive information. Using combinations of large prime numbers means that anyone trying to crack such encryption needs to attempt to factor at least one of those numbers to get into encrypted data. When you buy something from, say, Amazon, the connection between your computer and Amazon is encrypted using that basic system (it's more complicated than that, but that's the rough summary). The time it would take a digital computer to calculate these factors is essentially past the heat death of the universe. (Still, this won't help you if your password is password, or monkey, or 123456. Please, people, use a password manager.)
Quantum computing, however, increases processing speed and the actual nature of the computation so significantly that it reduces that time to nearly nothing, making current encryption much less secure.
The IBM researcher that could make that happen is complicated, and it requires some background explanation. For starters, while a "traditional" computing bit can be either a 0 or a 1, a quantum computing bit can have three (or infinite, depending on how you want to interpret the concept) states. More specifically, a qubit can be 0, 1, or both.
Up until now, the both part of that caused some problems in realizing the power of quantum computing.
Apparently — and you'll have to take this on faith a bit, as it hurts my head to think about it — the both state can switch back to either 0 or 1 at any given point, and sometimes incorrectly, based on the logic in the programming. Think about when your phone freezes up for a second or two while you're matching tiles. This is its processor handling vast amounts of information and filtering out the operations that fail for any number of reasons, from buggy code to malware to basic electrical noise. When there are only the two binary states, this is a process that usually happens behind the scenes and quickly.
The hold-up with quantum computing up until now is that the vastly greater potential for errors has stymied attempts to identify and nullify them. One additional wrinkle in this reading quantum states is familiar to anyone with basic science fiction knowledge, or perhaps just the ailurophobics. What if the action of reading the qubit actually causes it to collapse to 0 or 1?
The very smart people at IBM think they've solved this. The actual technical explanation is involved, and well beyond my ability to fully follow, but the gist is that instead of just having the qubits arrayed in a lattice on their own, they are arranged such that neighbors essentially check each other, producing the ability to check the common read problems.
That opens the door to further quantum computing developments, including ones that will make your password a thing of the past. So, does this mean that you need to start hoarding gold? No, not yet. And hopefully before quantum computing reaches commercial, or even simply industrial/governmental levels, a better cyber security method will be in place. Or the robots will have already taken over. I for one welcome them.
Science Confirms: Watching Online Cat Videos Is Good for You
Looking at Grumpy Cat’s underbite and feline dwarfism just might just make you feel better about your bratty kid, your nagging spouse or your demanding boss. That’s right, according to a new study published in the journal Computers in Human Behavior, watching cat videos online reduces our negative feelings while raising our sense of well-being and boosting our energy levels.
Grumpy Cat, whose real pet name is Tardar Sauce, shares a manager with fellow YouTube stars Keyboard Cat and Nyan Cat. Last we checked, the famous feline had 7.7 million Likes on Facebook. In all, more than 2 million cat videos were posted on YouTube last year, gathering nearly 26 billion views. Cat videos had more views per video than any other category of YouTube content. That makes kittens more valuable eye candy than, say, Maxim’s Hot 100. (Taylor Swift topped the list this year, just in case you were wondering.)

For the new study, Jessica Gall Myrick, an assistant professor at the Indiana University Media School, surveyed nearly 7,000 Internet users about how watching cat videos affects their moods. She got a little help from Bloomington, Indiana resident Mike Bridavsky — the owner of Internet celebrity cat Lil Bub — who used social media to recruit participants for the survey.
The results should make you feel a bit less guilty about clicking through one cat video after another: “Even if they are watching cat videos on YouTube to procrastinate or while they should be working, the emotional pay-off may actually help people take on tough tasks afterward,” Myrick says.
Don’t think watching cat videos online is a pop culture phenomenon worthy of academic research? Myrick disagrees: “If we want to better understand the effects the Internet may have on us as individuals and on society, then researchers can’t ignore Internet cat videos anymore.”

McDonald’s Slims Down in the U.S. for the First Time
For the first time in at least 45 years — and maybe the first time in its history — McDonald’s says that this year it will close more restaurants in the U.S. than it opens.
An Associated Press review of McDonald’s filings with the Securities and Exchange Commission found that the company hasn’t slimmed down the number of restaurants it operates in the U.S. since at least 1970. McDonald’s as we know it was founded in 1955 and grew quickly in its early years, making it likely that 2015 will be the first time it takes down more Golden Arches than it puts up in the U.S.

McDonald’s does shutter underperforming locations every year, but up until now the number of closings has been outweighed by new openings. The world’s biggest hamburger chain has been struggling to grow sales as consumers turn to chains like Chipotle and Five Guys Burgers and Fries, which market themselves as serving better food and ingredients.
McDonald’s is still growing globally, though. It has about 36,000 locations across the globe and plans to expand that total by about 300 this year. In addition, the chain is still indisputably the country’s largest hamburger chain, with more than twice as many restaurants as its main rival, Burger King.
McDonald’s spokeswoman Becca Hary told the AP that relative to the roughly 14,300 U.S. locations, the net reduction in U.S. stores would be “minimal,” though she declined to give an exact number.
More Money Coming Out of 401(k)s Than In
The amount of money withdrawn from 401(k) plans exceeded the amount contributed to the retirement funds for the first time in 2013, according to a report in The Wall Street Journal.
The shift reflects demographic changes as more Baby Boomer retire from the workforce and begin tapping their savings, and young millennial workers put smaller amounts in.
Consumers may benefit from the trend as fund managers begin cutting fees and changing services in order to entice young workers to sock away more. “It changes the dynamic of the business itself,” J.P. Morgan Chase analyst Ken Worthington told The Journal.

Company-sponsored 401(k) plans had $4.6 trillion in assets last year, according to the Investment Company Institute.
The average 401(k) balance at the end of the first quarter was $91,800, up 0.5 percent from the fourth quarter of 2014 and up 3.6 year-over-year, according to Fidelity. For employees in a plan for 10 years or more, the average balance was $251,600, up 12 percent year-over-year.
Workers can contribute up to $18,000 in pre-tax dollars to their 401(k) plans in 2015, but most workers—especially younger ones—save far less each year. There are lots of reasons millennials are lagging in retirement savings: large numbers of them are still unemployed or underemployed in jobs that don’t have retirement benefits, and they’re diverting all their extra cash to student loans. Plus, retirement may not be top-of-mind for 20-somethings, no matter how many times they hear about the benefits of compound interest.
Why a Woman Will be on the $10 Bill and Not the $20
The announcement that the Bureau of Engraving and Printing will add a woman to the portrait of Alexander Hamilton on the $10 bill has stirred a lot of conversation as to why the Treasury was not redesigning the $20 bill instead.
It turns out there is a very simple explanation: The move is based on recommendations from the Advanced Counterfeit Deterrence (ACD) Steering Committee.

"Currency is redesigned to stay ahead of counterfeiting," the US Treasury says. "The ACD Steering Committee recommended a redesign of the $10 note next. The ACD will make its next recommendation based on current and potential security threats to currency notes."
The ACD bases those recommendations on the "current and potential security threats to currency notes," and it turns out that the $10 bill is at a greater threat of being counterfeit than the $20 bill.
Secretary of the Treasury Jack Lew announced the change in a statement on YouTube: "I'm proud to announce today that the new $10 bill will be the first bill in more than a century to feature the portrait of a woman.”
Hamilton will share the note with a woman who Lew is expected to choose by the end of the year. The new bill will enter circulation after 2020.

FCC Slaps AT&T with $100 Million Fine for Throttling Internet Users
The FCC on Wednesday slapped AT&T hard, proposing a $100 million fine — the largest the agency has ever handed down — for what it described as the phone and broadband giant’s misleading customers about its “unlimited” data plans.
At issue is the practice of “throttling,” or limiting download and upload speeds for some users on those data plans.

AT&T’s throttling policy had been in place since 2011, according to an FCC statement, and it led to a barrage of complaints to the agency. AT&T targeted users who surpassed a certain data threshold over the course of a month, and consumer complaints argued that AT&T’s limiting of download speeds was directly at odds with the nature of the marketed “unlimited” plans.
AT&T, which is also pursuing government approval of its pending acquisition of DirecTV, says it will “vigorously dispute” the decision. In a statement, the company said that its practice is well documented and shared by many — if not all — service providers, and a legitimate method of managing their network’s resources. The FCC disagrees, claiming that AT&T violated transparency rules by falsely calling these plans unlimited.
"Broadband providers must be upfront and transparent about the services they provide,” said FCC Chair Tom Wheeler in a statement. “The FCC will not stand idly by while consumers are deceived by misleading marketing materials and insufficient disclosure."

AT&T has 30 days to respond before the FCC issues its final decision.
The Federal Trade Commission sued AT&T for $3.5 million in October last year, for the same alleged violation. That case is still ongoing.
