Move to voting phase for Best of 2019, and start Best of 2020 after 2019 is completely done Posting as an answer so that users can vote. Based on the comments on caird's suggestion, I think it's fine to simply go this way (it's arguably late, but it isn't too late yet, in the sense that we can finish this just before starting Best of 2020).

There appears to be more than one issue here. While I've fixed this part, something is still preventing low-rep users from posting both here and on Worldbuilding. I'll see if we can get that figured out and report back. So... funny story. I don't think this ever worked. We have site settings to change this and when I checked, the site settings were correct.....

Quickly! Group together! This challenge will function somewhat like an answer-chaining question, in that new answers will (somewhat) depend on old answers. However, this is (as far as I can tell) a unique form of answer-chaining, so be sure to read the entire challenge if you'd like to take part. Normally, answer-chaining challenges work in increments of ...

Best mathematical insight On this site we often see answers in languages specifically designed for short code, or designed to be fast. Sometimes, a nice golfing trick or speed-up technique surprises us with its ingenuity, beyond the standard use of that language. And occasionally an answer shows up that uses an unexpected approach to greatly simplify the ...

"Hello, World!" in zero lines of code NPM's sloc is a moderately popular tool for counting source lines of code in a file. The tool will attempt to strip out both single and multiline comments and count the remaining lines in order to get an estimate of the 'true' number of lines of code. However, the parser used is based on regular expressions and ...

Do not count extra bytes for using the specific setting, as long as it is actually runnable with auto-use enabled I decided to propose a reasonable policy myself. Please comment or add another answer if any of you have opinions or better suggestions. The existence of the specific .factor-rc file can be seen as a system-wide setting like APL's index origin. ...

All numbers are nice and round People generally consider numbers such as 15 and 950 to be round, and numbers such as 42 and 666 as not round. However, Wikipedia describes "round numbers" this way A round number is informally considered to be an integer that ends with one or more "0"s (zero-digit) in a given base. By this definition, all ...

(Almost) Solve Fermat's Last Theorem It's a well-known fact that Fermat's Last Theorem is true. More specifically, that for any integer $n \ge 2$, there are no three integers $a, b, c$ such that $$a^n + b^n = c^n$$ However, there are a number of near misses. For example, $$6^3 + 8^3 = 9^3 - 1$$ We'll call a triple of integers $(a, b, c) \ge 0$ a "...

Set of subsets without subsubsets You are given two integers $n$ and $k$, and are to output a random collection of $k$ sets $\mathcal A_1,\ldots,\mathcal A_k$ such that: each $\mathcal A_i$ is a subset of $\{1, 2, \ldots, n\}$; no $\mathcal A_i$ is a subset of another $\mathcal A_j$. Any collection which satisfies these constraints should ...

Arn Arn is a rather new J-like language I designed back in mid-August. It's designed to beat out its inspiration and also be competitive against other, older golfing languages. Reasons While not necessarily the best language at golfing, there are certain tasks it excels at In particular, math, ranges, mapping, folding, and other such operations. Designed ...

Add++ Add++ is a language that combines both short commands and other golfing features with general usability and practical language features.
