Comment Re:Yes, for any mission (Score 1) 307

The difference between "some of them will die" and "all of them will die" is drastic. The first implies that some of them have a reasonable chance of survival. The government provides the training and supplies such that potentially all of them could survive with a reasonable expectation is that some of them will survive. I'd be ok with a voluntary mission with similar chances. I would not be ok with a mission where the expectation is that noone would survive.

How Many People Does It Take To Colonize Another Star System? 392

Hugh Pickens DOT Com writes: "The nearest star systems — such as our nearest neighbor, Proxima Centauri, which is 4.2 light-years from home — are so far away, reaching them would require a generational starship. Entire generations of people would be born, live, and die before the ship reached its destination. This brings up the question of how many people you need to send on a hypothetical interstellar mission to sustain sufficient genetic diversity. Anthropologist Cameron Smith has calculated how many people would be required to maintain genetic diversity and secure the success of the endeavor. William Gardner-O'Kearney helped Smith build the MATLAB simulations to calculate how many different scenarios would play out during interstellar travel and ran some simulations specially to show why the success of an interstellar mission depends crucially on the starting population size. Gardner-O'Kearny calculated each population's possible trajectory over 300 years, or 30 generations. Because there are a lot of random variables to consider, he calculated the trajectory of each population 10 times, then averaged the results.

A population of 150 people, proposed by John Moore in 2002, is not nearly high enough to maintain genetic variation. Over many generations, inbreeding leads to the loss of more than 80 percent of the original diversity found within the hypothetical gene. A population of 500 people would not be sufficient either, Smith says. "Five hundred people picked at random today from the human population would not probably represent all of human genetic diversity . . . If you're going to seed a planet for its entire future, you want to have as much genetic diversity as possible, because that diversity is your insurance policy for adaptation to new conditions." A starting population of 40,000 people maintains 100 percent of its variation, while the 10,000-person scenario stays relatively stable too. So, Smith concludes that a number between 10,000 and 40,000 is a pretty safe bet when it comes to preserving genetic variation. Luckily, tens of thousands of pioneers wouldn't have to be housed all in one starship. Spreading people out among multiple ships also spreads out the risk. Modular ships could dock together for trade and social gatherings, but travel separately so that disaster for one wouldn't spell disaster for all. 'With 10,000,' Smith says, 'you can set off with good amount of human genetic diversity, survive even a bad disease sweep, and arrive in numbers, perhaps, and diversity sufficient to make a good go at Humanity 2.0.'"

The 7-11 I used to frequent had a ethernet jack near the soda dispensers......this jack was where the nearby ATM was plugged in. It would have been quite easy for me to insert any sort of device between the ATM and the jack. There was enough space between the jack and the ATM and there was also a valid reason for me to be in the area that it wouldn't look like I was doing anything with it. While it wasn't an official bank ATM (unaffiliated), I still could have been malicious had I wanted to. [I also never had a reason to use that ATM and am always wary of using an ATM that isn't physically at a bank...not that those are drastically safer.]

I agree. I think the current "future" is Single Page Applications with HTML and Javascript (subject to change at a moment's notice).....whether it's Angular or Knockout based, SPA apps seem to be the way to go (for now). It's probably the closest we've come to the write once / run anywhere......it works on the desktop and on the device, doesn't require anything other than a decent browser, and requires very little infrastructure (a basic web server).

Comment Re:Practical application is the only way (Score 2) 306

This, but also get a mentor. I more or less took a guy through this type of exercise and had him rewrite the same application four times to teach various concepts. But by being his mentor, he was able to grok the design considerations of the new technology to even know what to look up......

Rewriting an app the same way you always have but in a new platform doesn't teach you the best practices and new approaches. And not having the knowledge or experience to know the better ways makes it really hard to search for them. A mentor's job is to point you in the right direction.

Silicon Valley Billionaire Takes Out $201 Million Life Insurance Policy 300

Hugh Pickens DOT Com writes "The Mercury News reports that somewhere in Silicon Valley, a 'mystery billionaire' has bought what the Guinness Book of World Records says is the most valuable life insurance policy in history — a policy that will pay his survivors a cool $201 million. Was it Larry Ellison? Eric Schmidt? Elon Musk? Zuck? Nobody knows because the name of the buyer is a closely guarded secret. 'We don't want hit men running around Palo Alto trying to find him — or members of his own estate,' joked Dovi Frances, the Southern California financial services provider who sold the policy. By last count, California boasts 111 billionaires with more than a third of them in tech, while San Francisco has 20 billionaires alone so it could be any of them. But why does a billionaire even need to take out life insurance when he or she has so many other assets. The most likely answer to this question is taxes and estate planning.

Upon death, an estate would be liable to pay off loans on any leveraged properties, plus a lot of money as part of the death taxes owed. This could force the estate to liquidate holdings to raise the money to pay off these liabilities even if it weren't the most opportune time to sell the assets. By taking out the life insurance policy, it would give the estate more flexibility in paying off the taxes and other debts owed, without necessarily having to sell assets to do so. 'In California, there are state death taxes that are exceptionally high (45 percent),' says Frances adding that the policy is actually a combination of more than two dozen policies, underwritten by 19 different insurers because if any single company had to pay out such a lavish benefit, it could be crippling. 'If your properties are leveraged then those loans are called immediately and need to be paid off, you want to hedge yourself against such a risk so [your beneficiary] can receive the proceeds without being exposed to taxes.'"
