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.
Americans Just Went on a $32 Billion Credit Card Shopping Spree
Americans may be heading for another credit card crunch. After paying down almost $35 billion in credit card debt in the first quarter of the year, consumer charged up a storm in the second quarter, racking up $32.1 billion in new debt, according to CardHub, a credit card comparison site. CardHub says that’s the second highest quarterly total since it began keeping data on credit card debt in 2009.
While that buying binge could potentially signal improved confidence in the economy and in their own financial prospects, CardHub warns that the debt risks are building. It projects that consumers will close out the year with an annual net increase of more than $60 billion in credit card debt, with the total credit card debt outstanding climbing to more than $900 billion, the highest since the recession.

CardHub CEO Odysseas Papadimitriou says that jump brings Americans “perilously close to a tipping point at which balances become unsustainable and delinquency rates skyrocket.”
For 7 out of the past 10 quarters, consumers have racked up more debt than they’ve paid off. Papadimitriou cites that as evidence that consumers are going back to the bad habits they had before the economic downturn.
CardHub based its study on data from the Federal Reserve, and if the results are a sign of trouble then another new report from the Federal Reserve Bank of New York suggests that problem is even worse than it looks. In a report called “Do We Know What We Owe,” the New York Fed found that people widely underestimate their credit card debt, telling the Fed’s survey-takers that it’s about 37 percent lower than what lenders say it is.
So if we are actually getting to a tipping point with credit card debt, it may be even closer than we realize.

Watch Jeb Bush Do His Best Donald Trump Impression with Stephen Colbert
Unless you've been in your own personal media blackout for the last few days, you're probably aware that Stephen Colbert kicked off his new show Tuesday night and that Jeb Bush was one of his first guests. While the maiden voyage of the new “Late Show” has drawn mixed reviews -- “promising, if he relaxes” says USA Today, referring to the host – the show provided plenty of entertaining bits and compelling if somewhat odd moments.
Like much of the show, Colbert’s conversation with Bush was a mixed bag. Both host and guest seemed a bit nervous and some of their lines fell flat. Surprisingly, one of the more entertaining parts of their conversation never made it on air: Colbert had Bush read some text written in the bombastic voice of Donald Trump. Bush was game for the joke, and the results are worth a look.
The fun at Trump's expense starts at the 2:32 mark, when Stephen Colbert refers to the "big, orange elephant in the room."

Here’s Why Home Prices Are Climbing So Quickly
Want to buy a home but finding slim pickings? Blame the builders.
New home construction has not kept pace with the improving job market in recent years and is part of the reason that housing inventory is so scarce and home prices are growing so quickly, according to a report released today by the National Association of Realtors.
After over-building leading up to the housing bubble, developer laid off workers and scaled back construction by more than 75 percent. After the crash many of those workers migrated to other industries, making it harder for builders to quickly ramp up work. There are also fewer builders now than there were a decade ago, with many going bust in the bubble and others consolidating with competitors.

While home starts have come back since the recession, the new NAR report finds that in two-thirds of markets homebuilding activity has not kept pace with the number of newly employed workers. In particular, construction of single-family homes remains at less than half its prerecession levels.
Many of the markets with the largest disparity of jobs versus home construction were hit hardest by the housing crisis but have fully rebounded, including San Jose, San Francisco, San Diego and Miami. New York is also among the top cities where home building has not kept pace.
There are several reasons that new home construction has grown so slowly in recent years, including rising construction and labor costs and tight credit. Despite those headwinds, new home construction is expected to grow by more than 25 percent this year.

Millennials to Employers: Show Us the Money
When it comes to company loyalty, money matters to millennials. Twenty-nine percent of millennials say that a higher salary is the biggest contributor to their loyalty, according to data released Tuesday by the Staples Advantage Workplace Index.
That compares to 20 percent of the overall workforce who place a priority on salary. The difference could be related to the fact that millennials tend to make lower wages than other workers and face higher fixed costs on things like student loans and rent.
Still, the job market is tightening, making it easier for millennials who feel they are underpaid to look elsewhere for work. The unemployment rate for millennials has fallen by nearly 40 percent since its peak in 2010.

Millennials are willing to work long hours but they want to be able to do so on their own terms. More than half of younger workers said that they work from home after the work day is over, compared to 39 percent of the all workers. Nearly half of millennials said that increased flexibility would improve their happiness.
Other important factors for millennials are office perks such as a gym or free lunches, having an eco-friendly office and a company culture that encourages breaks.
Whether or not they’re happy with their current roles, millennials are looking toward the future with ambition. Seventy percent of those surveyed said they expect to be in a management position in the next five years.

Gas Prices at an 11-Year Low for Labor Day Weekend
Drivers will be paying less at the pump as we head into one of the largest travel weekends of the year. Gas prices over Labor Day weekend haven’t been this low since 2004.
The national average price of gas is currently $2.44 per gallon, 99 cents less than this time last year, according to AAA. The average consumer can expect to save $15 to $25 on each trip to the gas station.

AAA estimates that 35.5 million people are planning to travel this weekend, a 1 percent increase from last year. The majority of travelers, 30.4 million, are expected to drive to their destinations, a rise of 1.1 percent from last year.
Gasoline prices are moving lower thanks to the falling price of crude oil. Oil has been hit by worries over economic growth in emerging markets, Iranian oil flooding the market and crude oil inventories rising due to economic and weather factors, a U.S. Energy Information Administration report finds.
For drivers, there’s more good news ahead. AAA expects gas prices to keep falling, with gas selling for $2 or less a gallon by Christmas in many parts of the U.S.
