1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.

    [The list concatenation function] ++ is an infix function i.e. [1,2,3] ++ [3,4,5] = [1,2,3,3,4,5] (which will be equivalent to doing (++) [1,2,3] [3,4,5] by virtue of how infix functions work in Haskell).

    I think that's the part I was most confused by. I'm coming mostly from Java and C, where ++ would be the unary operator to increment a number. I would have expected that symbol in a functional language context to be a shorthand for + 1. The idea of it being an infix function didn't occur to me.

    Partial applications I remember from a class on Clojure I took years ago, but as far as I remember, the functions always had to come first in any given expression. Also, I believe partial fills the arguments from the left, so to add a suffix, I'd have to use a reversed str function. At that point, it would probably be more idiomatic to just create an inline function to suffix it. So if my distant recollection doesn't fail me, the Clojure equivalent of that partial function would be #(str % " Is Not an Emulator").

    iterate works the same though, I think, so the whole expression would be (def wine (iterate #(str % " Is Not an Emulator") "WINE") )

    This code was typed on a mobile phone in a quick break based off of years-old memories, so there might be errors, and given it was a single class without ever actually applying it to any problems, I have no real sense for how idiomatic it really is. I'll gladly take any corrections.

    NGL though, that last, readable version is sexy as hell.
