    Crowdsourcing also depends on the crowd for the most part being non-malicious and honest. Just imagine 'pranking' the system and the potential outcomes.

    Happily, filtering data to remove the outliers is a long solved problem. This makes pranking the system much more difficult.

    How much did Microsoft spend in-house developing Bing? Was it more or less than $45bn? How much of the drop in value of Yahoo! was from Microsoft entering the market as a competitor.

    Yahoo!'s value hasn't been in it's search engine since shortly before the turn of the century. Yahoo's value was as a platform - a huge gaming site, a massive email community, a huge business and stock community, the largest photo sharing/social site, etc... etc... The huge drop in Yahoo!'s valuation had very little to do with Microsoft and more to do with other competitors (notably Facebook) slowly chipping away those value centers while Yahoo! flopped and twitched and let it's business be taken away from it practically without a fight. Activist investors concentrating on short term rises in profit rather than long term management of the business didn't help any.

  6. From TFA: But the National Aeronautics and Space Administration doesnâ(TM)t envision getting astronauts to Mars until at least a decade later, a timeline NASA is finding increasingly hard to defend in the face of criticism that it is too slow.

    That criticism largely comes from the legions of ill-educated members of the Cult of Elon. Not that being ill-educated is all that notable in the space fandom community, it's practically a defining characteristic. Another defining characteristic is their credulity and inability to distinguish the gap between plans and power points and actual flying hardware.

    Much of the rest of the criticism comes from lazy journalists - bashing NASA or worshipping Musk is great for clicks. A two-fer is manna from heaven.

    And there's the folks who don't grasp that NASA isn't an independent organization - it's part of the Executive branch of the US Government. It's only going to go to Mars if it becomes Government policy and Congress and the Administration are behind the concept and fund it.

    And on top of all that is Musk's (in)famous overpromising and under or late delivering. He's an optimist, but not always realistic.

    While I have no doubt that Musk and SpaceX will eventually get to Mars... There's simply too many technologies and too many mission techniques to master for a mission to be likely in the timeframe he proposes. Yes, they're already building the BFR - but while the booster is the most visible and sexy piece of the system, it's only one piece. (And one that hasn't flown yet.) Notably absent from Musk's discussions, beyond vague hand waving of intent, is any mention of progress on the flight hardware. It'll no doubt be built on a modified Dragon, but that's just the hull, again one part of the overall system.

    Facts like the fact that Musk never said he had approval from New York City - that he actually said, "verbal govt approval". Which he did - the government he was speaking of was the federal government

    The federal government lacks the authority to make such a commitment. And if you actually read the article you linked, and even the text you quoted, no commitment is to be found. But hey, let's leave that part out.
     
     

    Facts like, for example, that Model 3's production schedule had been moved forward to July (was originally supposed to start at the end of this year), with Musk stating at the time that the reason for the July deadline was because he knew some suppliers would inevitably fail to meet their deadline and he had to have a way to hold their feet to the fire with real penalties for failing to deliver. Of course, they actually did make the July deadline.

    Since they weren't talking about the July deadline... this is relevant, how? He promised delivery of 'x' in September, he failed to fulfill that promise. But hey, let's leave that part out.
     
     

    The Wall Street Journal will gripe about the fact that there are missing features in the (over-the-air-upgraded) software stack and that there's some manual labour / part changes in manufacture because automated assembly line isn't yet complete.

    Um, no. The plan was to produce 1500 vehicles. He failed to do so. But hey, let's leave that part out.

    Also, saying he only delivered 17% of the cars they had planned is distorting the truth a bit. They planned to deliver 100 in August and 1500 in September, ramping up to around 5000 a week by the end of the year. So if they only delivered just over 200 cars in September, that's less than a month's delay which is peanuts compared to other Tesla delays in the past.

    Yeah, they rounded a bit. 200/1500=.1333

He put his hand on them and slowly started inching it along them towards the plane defined by the ropes that marked the security area. When his hand was just short of breaking the plane, I took my nightstick out and laid the tip on the pipe just touching his fingertips. He took his hand back, made a note and stepped back. There was a positive comment in the final report "during inspection of the [can neither confirm nor deny] operations the security guards were notably alert and forehanded* in the conduct of their duties".

    Then there was time a bomb threat was called away* and I found an "officer" wandering around unescorted. (During security situations we were supposed to pair up.) My partner and I had to forcibly and bodily haul him to the wardroom. (We didn't actually have to take our nightsticks to him, but it was close.) Turned out he was an officer who had just reported aboard and his escort had abandoned him. Got chewed out by the COB for manhandling an officer. Got congratulated by the XO for alert and proper handling of the situation. The escort who bailed went to mast and lost a stripe and half his pay for thirty days. The officer hated me until he learned the truth of how such situations were supposed to be handled. (That is, exactly as I handled it.) When he later became my division officer, he'd frequently bypass the chief (who was an idiot anyhow) and seek out my advice.

    Also got chewed out by the COB for taking charge at the scene of a another security drill... He'd wanted to see how the guy sitting next to me would react. I just told him piss off, I was there and trained specifically to handle that situation and the guy next to me wasn't. If he wanted to see how guys with less specific training would react he shouldn't have done what he did in front of a guy who was. Not my fault he wasn't paying attention.

    They may be horrible places to build in terms of natural disasters, but they are very advantageous places to build in terms of economics. Economics affects our lives every day. Natural disasters affects our lives once every few decades.

    Mexico City is built on an ancient lake bed. That makes the ground very flat, which again is economically advantageous when building infrastructure (you can construct it cheaper). That lake bed is also what makes earthquakes there so bad.

    The flaw in your argument is this: When Mexico City was founded, other than a small artificial island, it was all hills around a lake. The lake was drained to build the city, rather than building the city on a former lake. Forced labor made it cheap to drain the lake, but today it's very expensive to maintain the infrastructure to keep it drained and to prevent seasonal flooding. The Valley of Mexico is a giant bowl with no natural drainage - if they ever stop maintaining those drains, it'll promptly turn back into a lake.

    In the same way, there was no particular economic reason to build Mexico City (it's far inland in an era when trade was based on the coast among other things) - but one overwhelming political reason. It was built on the site of Tenochtitlan, the capital of the most powerful of the conquered nations.
