   Thanks for taking the time to explain. While I haven't experienced much joy in reading mathematics so far (beyond a select few books), maybe I'll understand in a few years.

   Maybe. I'd like to hear back from lutusp before I jump to that conclusion.

   I liked Concrete Mathematics by Ron Graham, Donald Knuth, and Oren Patashnik. Get it from the library of a nearby university, read the first chapter, do the warm-up problems, then decide if you like it enough to read the rest. The authors h

   It's not technically wrong: 0 is indeed a "low probability". It's misleading, though.

    It's also super short, so you can easily glance over the source code to make sure it's not doing anything shady (it's not).

    Probably not, but that's not really the point. People do this this kind of math because it's fun.

    megrimlock has a poster of a Venn diagram on the wall. The intersections in the diagram represent interdependencies between different parts of a piece of software (in object-oriented programming terms: places where encapsulation is broken).

    Just curious: how did you find this? I don't see a link to it anywhere on Knuth's website. The only reference I can find to it is on Twitter[1]. [1] https://twitter.com/pervognsen/status/230892091188846592

    It works. Common Lisp just happens to have a function built in (substitute) that does pretty much what the problem asks for.

    Was the title change really necessary? No one knows what "The Construct" is, but a lot of people know what "Fluid Simulation in 9 Lines of Code, and More on Fast Simulation Prototyping" is.

    355/113 is actually [3,7,15,1]. The reason it's particularly good compared to its length is because it falls right before the 292 term (since 1/292 is a much smaller contribution than 1/1).

    object["method"](params) is just an alternative syntax. Normally you would do object->method(params).

    Putting the data argument second is nice when combined with currying. For example: var bigNumbers = Udon.curry(Udon.filter)(function (number) { return number > 5; }); bigNumbers([3, 1, 4, 1, 5, 9]); // [9] bigNumbers([2

    How about both? Udon.flip = function(f) { return function(x) { if(arguments.length > 1) { return f(arguments[1])(x); } return function(y) { return f(y)(x); };

    JavaScript's prototypes really are poorly designed, though. To see how it probably should have been done, check out the programming language Io ( http://iolanguage.com/ ) or Douglas Crockford's note on prototypal inheritance in JavaScript a

    I really did interpret it in the same way as aheilbut initially (i.e., I initially thought that the author was just whining). However, I realized I was probably missing something, so I decided to ask. Fortunately for me, you came along and

    I understand your viewpoint here, because that's more or less how I interpreted the article on my first read through. However, you likely misinterpreted the article. See pnmahoney's response to my comment: https://news.ycombinator.com/item

    Thanks. After reading your comment and rereading the article, I agree with your interpretation (but I can't stand the author's presentation). It's too bad that the author chose to put the "male" spin on things[1][2][3][4]. I found that offe

    Can someone explain to me what the author is trying to say? I see two things in the article: 1. In the author's eyes, the majority of early Facebook employees acted in a juvenile masculine manner[1]. 2. Some of those early Facebook employee
