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.
This Is What America’s 'Dream Home' Looks Like
The dream home for today’s American consumer is just over 2,000 square feet and located outside of a major city, according to a report out today by Trulia.
Consumers polled by the real estate Web site said the top features in their dream home were a backyard deck, a gourmet kitchen, and an open floorplan.
Owning a home is still part of the American dream for 70 percent of those polled, down from 77 percent five years ago. The portion of Americans who want to buy a home one day was highest—hitting almost 90 percent—among millennials.

Those findings echo the results of a Wells Fargo poll in June, which found that nearly two-thirds of consumers say that home ownership is a “dream come true” and an accomplishment to be proud of.
Despite the desire for home ownership, only 14 percent of those surveyed by Trulia said they would buy a home this year. Nearly 70 percent said they planned on waiting at least two years to make a purchase.
The country’s home ownership rate fell to 63.7 percent in the first quarter, the lowest level since 1989. The rate peaked at 69.2 percent in the fourth quarter of 2004, right before the housing bubble burst.
Just 36 percent of millennials who want to buy a home are currently saving to purchase one. As rents in many cities continue to skyrocket, however, homeownership may become more appealing.

CVS Quit Selling Cigarettes, but It’s Found a Patch for Sales
CVS executives knew that some of their sales would go up in smoke when they decided last year to stop selling cigarettes. The press release announcing that all 7,600 CVS stores nationwide would stop selling all tobacco products acknowledged that sales would take a hit. Still, the company said, “This is the right thing to do.”
The costs of the decision are now becoming clear. CVS Health’s general merchandise sales slumped 7.8 percent last quarter on a same-store basis, the company said Tuesday. The company claims non-pharmacy sales would have stayed the same if tobacco sales — and the other products cigarette buyers added to their baskets — were removed from sales figures for the same quarter in 2014.

Same-store sales in the pharmacy category climbed 4.1 percent, boosting overall same-store sales growth to 0.5 percent compared with the second quarter of last year, down from a 1.2 percent year-over-year increase the previous quarter. Net revenue overall grew by 7.4 percent to $37.2 billion, helped by pharmacy services revenue that surged 11.9 percent ($2.6 billion) to $24.4 billion. The company has reportedly increased its market share in the health and beauty categories (it did, however, narrow its full-year earnings forecast).
So even as the move to drop cigarettes has cost the company, its bet on health as the source of future growth may be starting to pay off. CVS stock dropped in the wake of its earnings announcement, but shares are still up more than 15 percent on the year and 44 percent over the past 12 months.
Is the American Dream Dead? Most Parents Think Their Kids Will Be Less Well Off
Parents think their children will be happier and healthier in the future as adults, but also less well off, according to a new report commissioned by insurance company Haven Life.
Only one in eight Americans believe that their children will be better off financially, when compared to their parents. More than half of American parents believe their children will have less disposable income in the future, and only one in five Americans believe their children will enjoy greater quality of life.

On the other hand, more than 60 percent of adults believe that future generations will lead “as healthy or healthier” lifestyles than adults today. And half of them think their children will grow up to be more environmentally conscious adults who lead greener lifestyles. More than half believe that this future generation will be more ethnically and racially diverse.
The study was done by YouGov for the Haven Life Insurance Agency. YouGov conducted an online poll with a representative sample of 1,124 U.S. adults in the first quarter of 2015.

Travel Nightmares: How to Avoid Getting Bumped from Your Flight
You're finally on your way out for a summer vacation. The flight was booked months ago. Your bags are packed and ready. You arrive at the airport the recommended 90 minutes before the scheduled departure time (because it's a great long trip, and you've decided to check your bags). After enduring the inhumanity that is the TSA line, you get to your gate. Of course, everyone else has done the same thing, and you hear the familiar strains of "this flight is overbooked, we are offering a travel voucher if you are willing to fly on a later flight."
But you ignore that, as always, because, well, your bags are already on the plane, and you don't want to miss even a second of your long-awaited time away. Still, that $300 voucher sounds tempting. You could use it to help defray the cost of holiday travel in a few months.
Don't do it. Resisting that temptation can be even more rewarding: If the worst still happens and you get involuntarily bumped, you can get a full refund of your ticket price plus up to $1,300 in added compensation.
The AirHelp inforgraphic below lays out the basic dos and don'ts of dealing with an overbookd flight. You can also find more from AirHelp here.

Blame China for Your Costly Lobster Roll
Looking for authentic, down-home Maine lobster? Head to China.
The upsurge in demand for lobster in China this year has caused the price of the succulent marine crustacean to shoot up to record highs in the U.S., according to Bloomberg News. Wholesale prices for lobsters have clawed 32 percent higher over the last year.
Lacking a lobster industry itself, China used to rely on Australian imports to meet the demand from an expanding middle class that views lobster as a status symbol. But in 2012, as catches off of Western Australia began dwindling and prices of lobster fell in the Gulf of Maine, China changed its main supplier to the U.S.

Lobster exports from the East Coast are the main reason for the hike in fish and seafood exports to China in recent years, according to U.S. Department of Agriculture data. Over the past seven months, about 60,000 live North American lobsters a week make the 7,500-mile trek halfway across the world. The lobsters must still be alive by the time they arrive in China or else they lack appeal, so they’re packed in wet newspapers and Styrofoam coolers for a trip that must be made in 18 hours or less, according to Bloomberg.
Another reason for the surge in prices was the bitterly cold winter this year, which slowed the catch in Canada and delayed the summer harvest in Maine.
Holding off on your lobster roll until next summer in the hopes that prices will wane? Don’t count on it. The Chinese middle class is still growing rapidly, and the country already consumes 35 percent of the world’s seafood — a number likely to increase.
