Comment Epic fail: someone always matches (Score 2, Interesting) 129

This scheme will work for one branch in Lesser Nowhere, Sechwan Province, with a finite and small set of pictures, and a small number of crooks. Once the number of faces increases, the probability of a false positive explodes, roughly as (N 2) (select every two out of N), where N is the size of the pools of pictures + the person being scanned.

The well-known example is the "birthday paradox", in which twenty-three people at a party increases the probability of two of them having the same birthday to fifty-fifty. That particular case was because the actual probability was multiplied by (25 2) = 25! / ((25-2)! * 2!) = 6900 comparisons being made, times 1/365 chances of a hit.

The German federal security service considered using one of my then employer's recognizers for airports to catch terrorists, but ended up facing the problem of accusing grandma of being part of the Bader-Meinhoff gang (;-)) No matter how accurate we were, a few more people in the pool would give us false positives. We'd need roughly an accuracy of 99.9 followed by roughly as many decimal places of 9s as there were powers of ten of people.

Future of Employment: How Susceptible Are Jobs To Computerization? 385

turkeydance writes: What job is hardest for a robot to do? Mental health and substance abuse social workers (found under community and social services). This job has a 0.3 percent chance of being automated. That's because it's ranked high in cleverness, negotiation, and helping others. The job most likely to be done by a robot? Telemarketers. No surprise; it's already happening. The researchers admit that these estimates are rough and likely to be wrong. But consider this a snapshot of what some smart people think the future might look like. If it says your job will likely be replaced by a machine, you've been warned.

If the tone of your post is any indication of what you are like in person, I believe that you may be entirely wrong, almost to the point of being polar opposite to reality, about their intentions about why they distance themselves... .

How Elon Musk's Growing Empire is Fueled By Government Subsidies 356

theodp writes: By the Los Angeles Times' reckoning, Elon Musk's Tesla Motors, SolarCity, and SpaceX together have benefited from an estimated $4.9 billion in government support. The figure compiled by The Times, explains reporter Jerry Hirsch, comprises a variety of government incentives, including grants, tax breaks, factory construction, discounted loans and environmental credits that Tesla can sell. It also includes tax credits and rebates to buyers of solar panels and electric cars. "He definitely goes where there is government money," said an equity research analyst. "Musk and his companies' investors enjoy most of the financial upside of the government support, while taxpayers shoulder the cost," Hirsch adds. "The payoff for the public would come in the form of major pollution reductions, but only if solar panels and electric cars break through as viable mass-market products. For now, both remain niche products for mostly well-heeled customers." And as Musk moves into a new industry — battery-based home energy storage — Hirsch notes Tesla has already secured a commitment of $126 million in California subsidies to companies developing energy storage technology.

total lifespan is still limited by other factorsLike what, exactly? If you can cure aging, then by extension, diseases that are induced by aging should also be eradicated. That just leaves dying by diseases where survivability is *not* significantly connected to how old someone is, death by accident, or else homicide.

In other words, some 70% of the reasons that people die will be eliminated. It is effectively immortality.

No, it's not the same story. The story now is about what Sourceforge did after that (i.e., locking the GIMP-for-Windows developer out of his account -- despite the fact that he had not "abandoned" it as Sourceforge claimed -- and distributing the crapware-bundled installer anyway).

Comment Re:Bad logic) (Score 1) 692

Many of the diseases that predominantly affect the older generations often arise not simply because of the passage of time, but as a consequence of the aging process itself... That is not to say that aging is necessarily the sole cause, but it is extremely obvious that declining health as one ages plays a very large factor. If certain medical treatments existed to genuinely halt or even reverse the effects of aging, then one's overall health would be expected to remain at otherwise "youthful" levels (in fact, if it did not, then the treatment doesn't actually do anything), and people would not tend to die from illnesses that are typically associated with declining healthy levels as one ages any more than people who have otherwise lived only to a relatively young age already do.
