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.
Two-Thirds of Parents Are Making This Big Financial Mistake
More than a third of Americans with young children don’t have any life insurance, and another third have policies with payouts of less than $100,000, according to a new analysis by Bankrate.com
The survey found that 42 percent of all Americans haven’t purchased life insurance, and about half of those with insurance have policies worth $100,000 or less, including 25 percent of those with a household income over $75,000.
Of course not everyone needs life insurance, but people who have family members depending on them financially should have a policy. The amount you need varies, depending on your future financial obligations, outstanding debts, and current assets.

Part of the reason for inadequate coverage could be that people underestimate the benefits they’re receiving from work (which don’t roll over from job to job), or they’re failing to update their policy after major life changes like the birth of a child or the purchase of a home.
Another factor: They’re misinformed about the price of life insurance. Eight in 10 consumers have incorrect ideas about the price of life insurance, with millennials overestimating the cost by 213 percent and Gen Xers overestimating it by 119 percent, according insurer trade organization LIMRA.
In addition to your age and health, the price of life insurance could be impacted by your credit history, driving record, and lifestyle.
The LIMRA study found that 30 percent of Americans think they need more life insurance, but more than half said it was unlikely that they’d purchase a policy in the next year.
The Rapidly Rising Death Toll of the Heroin Epidemic
The death toll from the heroin epidemic has been climbing dramatically in recent years — and the annual rate of overdose deaths nearly doubled between 2011 and 2013, according to a new CDC study.
From 2002 through 2013, heroin use in the United States rose by 63 percent, and the rate of abuse or dependence climbed a staggering 90 percent. Deaths from heroin-related overdoses nearly quadrupled, with more than 8,200 people dying in 2013 alone.
The CDC report says that heroin use has increased across most demographic groups — men and women, most age groups, and across all income levels. Rates of heroin use are still highest among men, those ages 18 to 25, people with income less than $20,000 a year, people in urban areas, and those who do not have health insurance or are on Medicaid. But other groups are turning to the drug, too. “Some of the greatest increases occurred in demographic groups with historically low rates of heroin use: women, the privately insured and people with higher incomes,” the CDC says.
The heroin trend isn’t happening in isolation, the CDC study says. Almost all heroin users — 96 percent — also took at least one other drug, and 61 percent used at least three other drugs. Abuse or dependence on opioid painkillers is the strongest risk-factor for heroin use or addiction, the report says, with cocaine addiction also high on the list. People who are addicted to prescription opioid painkillers are 40 times more likely to use or be addicted to heroin, and 45 percent of people who used heroin were also addicted to painkillers.
Another key reason is that heroin is becoming cheaper and more widely available. According to the DEA, the increase in heroin seizures in the U.S. from 2010 and 2014 rose 81 percent, from 2,763 kilograms to 5,014 kilograms. More and more law enforcement agencies are identifying heroin as their primary drug threat, but the CDC report suggests that health care workers focus on reducing the abuse of painkillers by improving prescribing practices.
The study also recommends that states increase access to “medication-assisted treatment” programs that use methadone, buprenorphine and naltrexone along with behavioral counseling. And it says the rapid rise in heroin-related deaths highlights an “urgent need” to broaden access to naloxone, a drug that can reverse the effects of heroin and opioid overdose.
Here’s Why Economists Are Worried About A New Housing Bubble
After posting their 39th consecutive month of year-over-year price gains, home prices in 33 states and the District of Columbia are at or within 10 percent of record highs, according to a report issued today by CoreLogic.
Home prices increased 6.3 percent year-over-year in May, and 1.7 percent month-over-month. Relatively low mortgage rates have helped fuel the price gains. In cities like San Francisco, where there is limited supply and high demand, prices are growing at a double-digit clip.
Prices are so high in certain areas that some economists are starting to worry about localized bubbles. The number of homes on the market is increasing slightly. Total housing inventory at the end of may reached 2.29 million houses, 1.8 percent more than this time last year, according to the National Association of Realtors. That’s a 5.1-month supply, giving sellers a slight edge in today’s market. (A six-month supply is considered a healthy market.)

South Carolina saw the biggest price gains, with homes showing annual appreciation of 10.3 percent. Other states showing big gains were Colorado (9.8 percent) and Washington (8.8 percent), CoreLogic reports.
High prices have also spurred builders to start constructing new single-family homes, sales of which increased 23 percent year-over-year in May.
While most states have seen price gains, five states (Massachusetts, Connecticut, Maryland, Mississippi, and Louisiana) saw local home prices fall in May.
CoreLogic economists expect prices to increase 5.1 percent year-over-year in June and 0.8 percent month to month.
Looking for Likes? When to Post on Facebook for Maximum Attention
Trying to decide when to post photo updates to your “Summer 2015” album so the maximum number of people click through, comment on, and like your filtered selfies? Look no further. A new study conducted by the social media analytics firm Klout can tell you the best time and day of the week to post on Facebook and Twitter, depending where you are in the world.
The study found that posting in the late morning and early afternoons on Tuesdays and Wednesdays tends to generate the most engagement. Thursdays tend to be quiet, Fridays are quieter still, and the weekends are the quietest. On Mondays, the activity level begins to ramp up again as the work week begins and bored office workers take social media breaks.
Optimal times also depend on location. Tokyo peaks at the earliest time among cities studied, between 7 a.m. and 9 a.m. Paris has a high level of engagement once in the morning and once in the afternoon. In San Francisco, between 9 a.m. and 10 a.m. is ideal for posting. The most favorable time in New York is just before noon. London peaks the latest, with users becoming fully engaged on Twitter and Facebook only in the early afternoon.
Thinking about posting a picture of your cute new nephew at night? Don’t even bother if you want maximum engagement from your followers and friends. While one explanation is that fewer people are online at night, another is that most likes, shares, and comments occur within a short window of time after someone posts something. Researchers of the study found the majority of reactions were within the first two hours of posting time.
Using a sample set of half a million active users and more than 25 million messages over 56 days, the report boasts a reaction gain of up to 4 percent on Twitter and 17 percent on Facebook when the recommended posting times are used.
Why We All Buy Tide: The 10 Biggest Advertisers in the U.S.
The 200 top national advertisers spent a record $137.8 billion last year trying to get you to buy more of their goods and services, an increase of 2 percent over 2013, according to Ad Age’s latest annual spending review.
That total was slightly more than the GDP of Hungary last year, but the growth rate was the lowest since 2009, as advertisers looked to get the most for their money. Internet display advertising among those 200 marketing Goliaths dropped by 13.3 percent.
Overall, 38 marketers spent more than $1 billion on advertising last year. Procter & Gamble remains the country’s (and the world’s) largest advertiser. It shelled out $4.6 billion in the U.S. alone to promote brands such as Crest, Duracell, Pampers and Tide — or well over $1 billion more than the next biggest spender. P&G’s CFO recently revealed plans to cut ad spending by as much as $500 million, though.
Here’s Ad Age’s list of the 10 biggest advertisers in the U.S. last year:
