Husk, 8 bytes S+s"S+s" Try it online! Basically Leo's original quine. It concatenates the string evaluated version of S+s to itself. So: "S+s" + "\"S+s\"" gives the original code.
Vyxal/Keg , 8 bytes `:.,`:., Try it online! (Keg) The explanations are the same for both languages, seeing as how Vyxal is heavily based on Keg. Explained `:.,` # Push the string ":.," :., ...
Rules Using your language of choice, golf a quine. A quine is a non-empty computer program which takes no input and produces a copy of its own source code as its only output. No cheating -- ...
ARBLE, 15 bytes "Hello, World!" Simple use of Implicit IO. Polyglot with half a dozen golf langauges. Try it online!
APL (Dyalog Unicode), 11 3 1 byte ⊥ Try it online! Anyone who can golf this further gets a cookie! Function submission which takes reversed coefficients as right argument and $x$ as left ar...
Python 2, 76 bytes i=27 while~i:print' '*i+' '.join(`min(i,j,27-i-j)`for j in range(28-i));i-=1 Try it online! Computes the digit in row i from the bottom, position j as min(i,j,27-i-j). F...

Challenge Given a list of n numbers and x, compute $a + bx^1 + cx^{2} + ... + zx^{n-1}$, where a is the first value in the list, b is the second, etc. n is at most 256 and at least 0. The input va...
Raku, 19 bytes "Hello, World!".say Explanation First second answer of the.. entire site, actually. Nothing special. I don't think this can go shorter, but this is Raku, who actually knows. I m...
Vyxal, 2 bytes KH This pushes the string "Hello, World!" to the stack and automatically prints it. Also, this is the first answer on the site! Woo!
Introduction The classic "Hello, World" challenge. What more can I say? Rules Program takes no input. Program outputs Hello, World! with an optional trailing newline. No other output is accep...
As we start on building a new community here together, we're bound to find some sticking points. Those might be bugs, new features you need, things you need support with... whatever they are, the C...
