@EthanBierlein FWIW that kind of semi-ignores the legal implications of wilfully ignoring active campaigning against SE on the SE platform
because 'murica you can't be a decent human if you're a platform owner and somebody is sueing you over something that happened on the platform while gaining significant support from the community of the platform
@Duga seems ok, clarification was explicitly requested in the comments.

Our guest this week is Kent C Dodds, a developer who makes a terrific impact on the community through his workshops, talks, and newsletter. We chat about why he loves React and how he automated his way from a business analyst to a full fledged software engineer.  Plus, the value of execution versus intelligence, and how version control worked in the days before Git.

The crew chats about how Paul and Sara made the transition from individual contributors to managers overseeing teams of engineers. Sara used to see this transition as a form of selling out, but has a new perspective after having mad …

Q: Quadratic "Complete the Square" Solver in Python 3

nokkoI quickly wrote this program to transform quadratic expressions in general form into vertex form. \$ax^2 + bx + c \;=\; a(x-h)^2 + k,\quad\text{where}\quad h = -\frac{b}{2a} \quad\text{and}\quad k = c - ah^2 = c - \frac{b^2}{4a}.\$ The actual conversion is easy, but with writing a lexer/parser ...

LinnyI've written a stack implementation in R using S4 Classes. I would like feedback concerning anything with the application because it's my very first program in R.

Since there is no error with the code you're trying to figure out, you should post this in the codereview mentioned by @Reimeus — Shar1er80 12 secs ago
Since your code works but you want improvement, you should probably try Code Review as it specialises in these questions. There is some overlap with SO sometimes but this site tends to be more about code that doesn't work. Also, can you post what the actual requirement is? — VLAZ 42 secs ago

How should this question be handled?
Q: Python script - Parsing molecular formula

a.couIs it possible to improve this code in terms of efficiency / line number ? (avoid nested code ...). It comes from a test I failed. I don't know how I could have done it better. from collections import Counter def parse_molecule(molecule): array = [[]] for token in map(str, molecule): ...

The consensus in the comments is fairly clear; the OP's original code is non-functioning. However, it doesn't appear that the OP themselves was (or is) aware of it.
this.emloyee(just) looks like a typo, so it is probably not correct. But in general, it helps to start with what your expectations of the code are. It is difficult for an outsider to judge whether code makes sense unless you know what it should do. If you are asking about code reviews, stackoverflow is not a good place to ask. Those questions tend to be closed quickly. — Philipp Claßen 59 secs ago
7:11 PM
@EthanBierlein That means it's on-topic per our scope.
Got it, thanks. I came across it while going through the close votes review queue, and I wasn't sure how to deal with it (ended up just hitting "skip").
People, can I have your attention please. If the code is improperly tested, that's too bad. But it is tested (badly) and OP was not aware of the code being awfully broken when posting. Per our current scope, that means the code is not off-topic and you lot could've been pointing this out in answers instead. Thank you, have a nice day. — Mast 7 secs ago
Questions about correctness in unanticipated cases are explicitly mentioned as on-topic in the help center.
To the best of my knowledge, does the code work as intended?
Yes? Good.
Next time, test better.
Good to know. Been a while since I've been active around here; seems like some policies have changed. I'll go back and take a gander through the help center.
Don't think that policy was changed, but feel free to ask if anything is unclear.
We're here to help after all @Ethan
Huh, will do. Maybe my memory is just acting up.

Q: Idiomatic lifetime management at FFI

stewbasicThe libretro-backend crate provides a Rust-friendly way to implement the libretro C API.

@Sam: "this is more appropriately asked on codereview.SE" -- only if they can improve the question. As asked, it would be off-topic there as well, because the code example is not complete. I have the impression that the codereview users are a bit tired of us stackoverflow users sending these kinds of poor questions to them. On any Stack Exchange site, it's important for users to read the tour and help sections before posting their first question. Sadly, most do not, or fail to heed what they have read. :( — Peter Duniho 43 secs ago
