<p>> it's impossible to do anything not en masse at 8b population<p>you are missing some simple arithmetic here. yes, x times y can get arbitrarily big if x does (and y is non-negative), but then changes in y would just have even more of an impact. take x to be population and y to be emission per person and you should see your mistake.</p>

<p>I've never seen any convincing argument that Bach is somehow, as frequently claimed, the epitome of baroque music. It seems to be a largely romantic sentiment, that arose moreso to Mendelssohn's circumstances than to anything unique in Bach's music— Mendelssohn simply did not have the access to many other high baroque composers' music to draw from. Aside from how surprisingly late he is, there are many comparable figures to Bach.<p>I am tired and will content myself with simply mentioning some early baroque composers that, for anyone curious, sadly do not get the spotlight they deserve: Ascanio Mayone (c.1565–1627), Girolamo Frescobaldi (1583-1643), Tarquinio Merula (1595-1665), Johann Jacob Froberger (1616-1667), Giovanni Antonio Pandolfi (1624-1687), Heinrich Ignaz Franz von Biber (c.1644-1704).</p>

<p>> The result of `longer_of` is a <i>projection</i> of the longer argument, so the mutation of `z` by `emphasize` occurs directly on the value of `y`. The value is neither copied, nor moved, and yet it is not being passed by reference to `emphasize`. The body of `emphasize` <i>owns</i> `z` in exactly the same way as it owns `strength`, which is passed by value: `z` is an independent value that can only be touched by `emphasize`.<p>This evasive phrasing, which continuoes after this excerpt too, has me highly skeptical of their good intentions… Any good reason they are not more explicit?</p>

<p>The author of this has clearly not read much of Tolkien's legendarium beoynd the LoTR... This is a whole lot of speculation that does not at all fit into Eä, the World that is. Though indeed one might say the same of Bombadil, it is far from clear what role he has to play in Arda, and Tolkien took his cosmology very seriously, so there is every reason to think this mystery of <i>who the hell is Tom Bombadil?</i> is intentional. But the reasonings of this article is exactly those of conspiracy theorists, not those of any serious Tolkien scholar. Seemingly relying on “No hobbit has ever heard of him,” “Elrond, the greatest lore-master of the Third Age, has never heard of Tom Bombadil” as implicitly implying “therefore there must be some great dark secret,” Gandalf's explanations he simply dismisses as not “the true one.” Tolkien was a philologist, familiar with and directly inspired by many different mythologies, for example Väinämöinen, a hero and demigod of songs and poetry from finnish folklore has been pointed out as a possible inspiration for Bombadil. Though from his close connection to nature one would rather expect him to be a sort of demiurge than a hero, neither evil nor good, and indeed as opposed to Väinämöinen whose adventuring is due to his seeking a wife, Tom <i>has</i> a wife and makes a big point out of this, he is content, and has no desire for evil. If I may continue my rant I'll add that the very creation of Arda is by music, taught by Eru Ilúvatar, the One, to the Ainur. There is little doubt that Bombadil is among the Ainur, one of the Maia on par with Gandalf and Sauron. It seems entirely plausible to me, that Bombadil indeed is as he says, the oldest, of special significance to Ilúvatar, prior to Arda and whatever may be happening in it.<p>I'll also add that I have never heard of any Tolkien enthusiast not liking Bombadil before this. I suspect the author of this article is among the minority who thinks that abruptly breaking into song is lame, mistakenly of course, hehe.</p>
