The color red is often associated with bad; needs to stop; wrong. Removal isn't such a big step from there, I think. The opposite probably applies to green.
I suppose it's an OK sentiment, but I'm not in contact with my parents and on days like these I keep getting reminded of that fact. I was secretly hoping there wouldn't be anything about it on HN, but I guess I'll just have to learn to deal with it.

I agree that concurrency isn't fundamentally hard, but the reason everyone kind of prefers faster serial execution is because a lot of algorithms (extremely simple example: f^100000(x)) are fundamentally unparallelizable. Faster serial execution is just so much more straightforward.
So a common problem with concurrency tends to be not "How do I make these functions run in parallel", but "Is there an algorithm that does the same thing I want without relying on constant function composition?"
Okay, but that's not actually an answer to my question. My question basically comes down to this:
> Yes, that is intellectually dishonest, which is a huge problem. Scientists have two options: (1) accept parapsychology as real, or (2) accept that the "scientific method" (in social "sciences", at least) is insufficient.
I don't get why the whole thing is such a huge problem. The entire problem rests on needing parapsychology effects to not be real. If that need did not exist, we could just go "Okay, interesting, seems likely that there's something to it then. Let's do more research!" because, you know, we take that approach everywhere else. So my question remains: what is it about parapsychology that makes option two even valid to consider? All I can see is people just not liking that that may be how things work.
So... I know next to nothing about parapsychology itself, but have seen a lot of the drama around it, and I just have to ask: is it not intellectually dishonest to call something the 'control group of science' when their results overwhelmingly support the hypothesis? I have a hard time seeing how this is different from any other form of science denialism. "We don't like the results because they clash with our preconceived notions of how the universe works so we made up this thing to ignore your evidence"? That's hardly a valid complaint. Basically, on what grounds can people claim one field to be nonsense (e.g. calling parapsychology the control group of science) but not others? Can someone explain this to me?
I'm not yet sure how to feel about this, but I have one question that remains unanswered: Will this apply to submissions (possibly in the future) as well?
Even in those extreme cases (which I hope we all agree are the exception rather than the norm), I would still consider putting someone in a few-square-meter box "cruel and unusual punishment" by any reasonable standard.
RWH is a good recommendation, although it contains a rather large number of errors. LYAH is very good for learning the basics, too.
But, if you're already a very experienced programmer, you can probably learn how to write practical programs in Haskell by just reading the IO chapter (http://book.realworldhaskell.org/read/io.html) and the Systems Programming chapter (http://book.realworldhaskell.org/read/systems-programming-in...) from RWH. These will help you understand how IO actually works in Haskell. The rest is just libraries and learning the language itself.
On a related note: I've found that starting with the main IO function is a good way to start writing any large program in Haskell. Most people I know who complain about Haskell being a mess in impure environments tend to write pure functions first, then build their IO functions on top of that, instead of the other way around. I'm not sure whether this applies for everyone, and of course this approach works well in domains that have little to do with IO (e.g. mathematical programming), but it's something to keep in mind.
Yes. Although I have no experience with Racket (so correct me if I'm wrong), the Lisps are inherently multi-paradigm languages. Haskell, on the other hand, is functional programming in its purest form. I would consider it worth learning if only for that reason, even if you don't end up using Haskell a lot.
EDIT: ...Did I just accidentally paraphrase what ESR used to say about Lisp?
Similar issues plague Haskell. A bunch of functions have illogical names, just because that's how they've always been used. And, there's the annoying matter of Applicative not being a superclass of Monad in the language, when it mathematically should be. This should be fixed in Haskell 2014, though.
