    > Part of the reason those shuttle launches were so expensive was that they carried a lot of science.

    Nope, that's not factored into launch costs. The Shuttle required a complete tear-down, rebuild and re-assemble after every flight. This was astonishingly expensive. Airline travel would be just as expensive if it had drop-tanks or launch boosters and required re-assembly after every flight. This is why single-shot rockets continue to dominate launches, the cost of the equipment is rarely as much as the cost of putting it back together.

    No it's not, the vast majority is due to the long lead times providing ample time for "something to go wrong" and the project goes into hiatus.

    Why? Because if the time-to-build crosses an election boundary, the cancellation probability goes non-linear. Not so much a problem where there are no real elections to speak of, like the Philippines during Marcos, but a serious problem for places that do have free elections, like the Philippines after Marcos.

    And as long as you keep blaming them for the problem, then the actual problem will never get solved.

    > Note: I'm not asking the impossible, climate change luminaries like James Hansen have called for nuclear power to be used

    Not impossible, just expensive. As the CAPEX is generally three to four times that of wind, and the lead times are four to five times as long, no one is giving them the money. That's it, end of story. Start here:

    http://www.lazard.com/PDF/Levelized%20Cost%20of%20Energy%20-%20Version%208.0.pdf

    Now turn to page 11. On-shore wind was going in for $1.40 to 1.80/Wp in 2014, it's gone down since publication. Combined with a 30% CF, that gives you an effective CAPEX/Wh of $4.66 to 6. Lazard gives $5.39 to 8.40 for nuclear, although it's gone up since publication (current average is around $9/Wp). Combined with an 85% CF, that's $6.35 to $10/Wh. Which means, all else considered, wind power costs around half that of nuclear.

    And that's why no one other than the Chinese, who are handing out billions of dollars of interest-free and risk-free money for infrastructure, is building them. And even their program is on serious hiatus. The money simply isn't there.

    The *actual problem* with nuclear is that practically every other option is cheaper and lower risk. It is, straight up, a bad investment. So unless you have a few hundred billion sitting in your bank account to buy one, guess what, you're part of the problem.

    > generated about 5 million edits per month

    Well anyone reading this who has even the slightest clue about how internet billing is handled, which I assume includes "thekohser", knows that the cost of hosting is based on throughput, not "the number of edits".

    So:

    1) the number of bytes per article in the English wiki has just under doubled since 2005:

    http://stats.wikimedia.org/EN/TablesArticlesBytesPerArticle.htm

    2) the number of page views has roughly doubled since 2008 (oldest number I have):

    http://stats.wikimedia.org/EN/TablesPageViewsMonthlyCombined.htm

    3) binaries have increased five times since 2005:

    4) the database as a whole has increased over eight times since 2005:

    http://stats.wikimedia.org/EN/TablesDatabaseSize.htm

    5) meanwhile the number of edits has grown only three times since 2005:

    http://stats.wikimedia.org/EN/TablesDatabaseEdits.htm

    If we consider bandwidth to be size times accesses, this implies that the total bandwidth has increased about 15 to 20 times since 2005. Yet the number of edits, which you have divided by, as increased only three times.

    So, then, that seems to go a long way to "explain a 30-fold increase in spending per edit", doesn't it?

    Good. And maybe by continuing this, they will convince more people to open up their locked-away storehouses of dead information so I can use it to write more articles. Because right now, that's my biggest problem, idiots like the IEEE that charge $31 for a PDF of an article published in 1946 on a technology that's no even used any more. Still interesting historically, but of exactly zero commercial value. So if all those visits and junkets get Nature or Science to start giving away content after a year, that's the best money ever spent by anyone, ever.

    var view: NSView = (NSView)anyObject

    It's just as explicit, yet this uses familiar syntax that everyone already knows and uses. For that matter, why did they decide to use this syntax:

    var view: NSView = (NSView)anyObject

    When:

    NSView view = (NSView)anyObject

    It exactly the same in terms of expressiveness, yet is using a syntax that we're already familiar with? Does adding var really make the code more clear? I certainly don't think so. And the colon? Really? I know the answer already, it's because they picked language X as their model rather than language Y, which is *precisely my point*.

Dylan, yes, *Dylan*, did this way better than any language I've seen since. You could have a private API, a public API, a beta API and a release API all from the exact same code.

    While it's true that using headers makes certain aspects simpler for the compiler author, it's also true that it pushes that work onto the end user - you - by forcing you to keep your headers up to date with manual edits. One could semi-automate this, but that's precisely the purpose of public/private. I have yet to see a real-world use-case where public/private didn't work.
