Shotgun Numbering
code-golfnumbersequencepermutations
The Shotgun numbers are defined as follows. Start with the natural numbers:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, ...
Now take all numbers at indices divisible by 2, group them into pairs, and swap the num...
if you look at the plot linked to on OEIS (under Links), many numbers fall into a handful of linear bands, but a lot of other numbers are all over the place
Don't get me wrong, it's your challenge, but what does it matter if the naive way is taken? Sure it's a bit trivial, but that's not exactly a new thing for code golf, is it?
ICS Maritime Flag alphabet
The International Code of Signals flag alphabet http://en.wikipedia.org/wiki/International_maritime_signal_flags is used by ships for communication, particularly for static signals.

@Runer112 Would you mind making a minor edit to your Sourcery post? I misclicked and downvoted instead of upvoted before I left the house, and now it's too late
This is a poll to find out the general concensus on the effectiveness of our Sandbox for Proposed Challenges.
To participate, up-vote exactly one of the answers below. There are only "Yes" and "No" answers. There is intentionally no "Maybe" answer, choose "Yes" or "No" as best you can.

but the girlfriend has a night shift tomorrow, so she's staying up late tonight to get into the cycle for the next three days... and since I don't have lectures tomorrow I'm staying up, too
I think it would be good if the high-rep users could go through the sandbox, sorted by votes and cast a few delete votes on the old negative-score proposals
Hmm, I'd say something like deleting all -3 or lower posts that are at least a month old (which is, at the time, all of them) would be fair. (don't want to abuse the super-delete too much)
I would like to make a code challenge (or a new type of challenge), which is based on code size, but in a "dual" way to code-golf: code size is limited, and the winner is whoever makes the best code (with some objective definition of "best").
Something like this challenge (which was awesome) but...
I have been doing some academic research in this area. The current coinage, which I think perfectly applies to the movement of the queen in chess, is octilinear. This term has been used to describe metro-map layouts that have followed Harry Beck's paradigm. The vertices of a unit-spaced octilinea...
@MartinBüttner Hey Martin, does Retina have a multiline match mode as in it prints the number of matches, one per line, for each line in the input file?
Not that it's necessary, just easier for bulk debugging
It's hard to beat the letters-per-syllable ratio of strengths either, e.g. for two syllables there's breakthrough (and maybe a few with a few letters more), but definitely not a 9:1 ratio
Shotgun Numbers
code-golfnumbersequencepermutations
The Shotgun numbers are a sequence with a rather simple definition but some interesting structure. Start with the natural numbers:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, ...
Now take all numbers at indices di...
@Runer112 awwww someone didn't like CJam on the staircase challenge

people there had a point, so you might not exactly be achieving the goal of the levelling the playing field as you intend, but I think it should nevertheless be an interesting challenge
you might want to consider counting the unique number of characters though
Regarding the Core Wars challenge, i can't decide whether or not to reverse the operands of the instructions. It could either match 8086 instructions or match the way Core Wars actually does it.
@MartinBüttner What are the current rules these days on things like "runnable program" vs "working method/function"; "return a string" vs "print a string" and so forth
What is the "proper" way to state in a question that I care as little as possible about that sort of code overhead
One of the things many (new?) users forget to specify in code-golf challenges is whether the answers should provide a full program or a function (or even just a snippet). For most such things, we have defaults in the tag wiki (like scoring by bytes), but not for this.
The conclusion in chat was ...
It looks like we have a consensus that we want certain defaults for the format which answers are expected in for code-golf. On that poll, the question arose twice, which input/output formats should be allowed for programs and functions.
So here is another poll. This one works different though. A...
in your case, the wording would be "You may write a program or function, returning the output as a string or printing it to STDOUT (or closest alternative). You may optionally include a single trailing newline in the output."
"At the end of the week, I will amend the code-golf tag wiki, allowing all methods by default which have 5 net votes and at least twice as many upvotes as downvotes. I will try to keep an eye on this in the future, to amend the defaults if the polls change."
(and the current result is indeed listed in the code golf tag wiki)
My basic guideline would be "as the problem statement says". Which is mostly to mean it's allowed to explicitly override anything it wants from what I'm about to say next.

For test-case/IO programs, I like it better when the whole invocation is possible as a single line, thro...

@Rainbolt what's that streaming site you've mentioned a couple of times lately?
It's very simple: Your program or function should generate the following text:
Elizabeth obnoxiously quoted (just too rowdy for my peace): "THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG," giving me a look.
Fine print
You may write a program or function, which returns the output as a string or p...
it doesn't really add anything over Prelude, I think... and I'm not much of a composer so I couldn't really make it nice anyway... I guess if there was an editor for Fugue which reads a Prelude program, where I can then just shift the intervals around, I might play around with it
meh, I'm trying to figure out a way to do FizzJazzBuzz in Mathematica without any control structures (merely with clever function definitions), but it's a bit tricky
