I concur. It is clear that at least a few people think it is acceptable on this site, which it (generally) isn't, and as such should be considered a standard loophole.
It's really cool! I knew it was a BF variant but I don't know them very well so I didn't take the time to go through and test it in various interpreters.
I love that it prints "Gotcha!" in C. That's so awesome!
@AlexA. By the way (since you're the one who asks about it), I received news today that my student aced the first half of her geometry test and is officially admitted to Algebra II! So I'm apparently not the worst teacher :P
I think I might have scared her away from EE when we talked about i :P She's definitely interested in taking more maths, and is thinking about engineering.
I believe, upon solving some kind of quadratic, I pointed out that sqrt(-1) was useful for describing lots of things even if it doesn't technically exist, and that it had close relations to the "fun" trig functions we were using. She looked at me like I was an alien, and far too excited about a silly number.
I've heard of that group, but I do not yet know anything about it :D
Well, you can't really say that to your geometry student without derailing the lesson even more :P I can't remember precisely what I said, but it probably involved delicately skirting around the existence of i.
I did not. That would be very weird. I chose to discuss far cooler things, like a little bit of history of Pythagoras (and the irrationality of root 2), and some Fermat's Last Theorem dabbling, and some sum(1/2^k) = 1 stuff.
If you would seriously consider the University of Washington for graduate school, most graduate programs in the sciences pay your tuition and a stipend but they require you to establish state residency within some time period so they don't have to pay out-of-state tuition for you.
Say I have text like this:

Golf
That makes no sense! It totally defies the laws of physics.
Your challenge is to remedy this impossible situation and collapse the text like so:

With the least amount of source code possible.
@AlexA. Seriously though, zipping an array of strings to collaps the columns is a common trick. I should add that to the tips question if it's not already there.
Write a term on the pure untyped lambda calculus that, when applied to a church-encoded list of numbers, returns it with its numbers sorted in ascending or descending order.
Example input:
(λ cons nil .
(cons (λ f x . (f x)) -- 1

@Dennis Reading the challenge, thinking of a solution, and implementing it in one of the few languages (all ill-suited for code golf) I know takes me well over 5 minutes. :P
User posts answer to own challenge immediately; refuses to compute actual score for his own answer; includes baity comment on how his answer will be the only one, so he's already the winner; undo's my edit removing his comment.
I'm not going to go in an argument or further edit wars to keep it civil - I'll let you handle it from here
Posts answer to own challenge immediately, IMO, not a big deal. It's a reference implementation. Ideally he should have waited but he's a pretty new user.
@AlexA. I don't know enough about lambda calculus to distinguish an obviously bad reference answer from a competitive one. Either way, posting a reference without computing its score is useless.
@AlexA. but I mainly take issue with the comment he put in his answer
@AlexA. It was more like looking at the desired output (ignoring the rest of the post for the moment), remembering that zipping twice would solve the challenge if we had to move the elements to the top and typing 11 characters. :)
@Dennis The only way I could think of in the languages I know to move things around like that is manipulating matrices column- or row-wise like I did in my R submission.
My brain doesn't think in zips because I'm not familiar with languages that use them extensively. I've used zip in Julia maybe once.
@AlexA. Well, CJam's zip and Pyth's transpose are a bit special. In the non-golfing languages I know, zip behaves differently for non-rectangular arrays.
@orlp I think at this point the comments handle it fairly well and the sentence is gone from the answer. It probably also wasn't that big a deal to necessitate an immediate edit - I think I would have rather commented as well. I could imagine it would just meant light-heartedly but came off the wrong way.

Write a program or function that given positive n and m calculates the number of valid distinct domino tilings you can fit in a n by m rectangle. You may take input in as function argument(s), CLA or on stdin, in any reasonable format. You must return or print a single integer as output.

For three of those: 1) I don't play Hearthstone, so it didn't interest me much 2) I've mostly avoided the whole GOLF cpu thing 3) Eww, AES. This is not to say these are bad in any way, just that they didn't capture my interest.
AES: I don't know much about it, so that would require research. Unique outputs: Getting an algorithm is okay, getting a good one is hard. Factoring: Yeah, learning GOLF. Hearthstone: Looked complicated at first glance, and I've never played the game

@aditsu I know what you mean. If visited the esolang page of one answer Sp3000 cracked later and even used the same language as another post (also cracked by Sp3000).
A backwards relationship
Write a program or function that given two ASCII strings will reverse the common substrings inside them. Common substrings are greedily searched from left to right.
Examples:
"hello test", "test banana" -> "hello tset", "tset banana"
"abcde", "abcd bcde" -> "dcbae", "d...

In my head I can (it makes sense given the task). I'm not sure how to clearly explain it in prose, but that's the point of using example inputs/outputs IMO.
For the first, the longest matching substring (from left) is abcd, so it reverses, leaving the e alone.
