The new title more than covers it. I like it. (more) |

(Alternatively maybe something other than "Convert" in the title, such as "Bijection from"?) (more) |

Interesting challenge. The spec seems complete to me, but I can imagine it being easy to make an incorrect assumption because "Convert" could lead to some people assuming that $f(x)$ is expressing $x$ as a binary fraction. Would it be worth stating explicitly that this is in general impossible so peo... (more) |

As there has been no preference expressed after some time, I've [added a fix](https://github.com/codidact/qpixel/pull/1616) (pending review) that sorts undefined scores to the bottom so they don't interfere with the order of the other scores.
I'm guessing this was the originally intended behaviour... (more) |

Formating an answer to work with the automated leaderboard How should I format my answer so that it works correctly with the automated leaderboard that shows under a challenge? - What is the required format? - How much flexibility is there? Once this has a comprehensive answer consider: - Adding it to the help system. - Linking to it from the an... (more) |

Missing usernames on leaderboard The automated leaderboard for each challenge previously showed the username for each answer row, but now it does not. I'm guessing a recent change to page layout has caused the JavaScript that generates the leaderboard to become incompatible. For comparison, there is a Meta question from a year ag... (more) |

I was torn between specifying an algorithm and leaving it as a part of the challenge to work out how to calculate the pattern. In the end I decided on not specifying at first, but adding an answer of my own as an example if no one answers for a while.
Do you think it would be better to have a spec... (more) |

| Question | — |
Transferable golfing skills We have many questions about how to golf in a specific programming language. These result in tips that apply only to that language or closely related languages. What advice do you have on golfing that applies more generally, to most languages? These may be algorithmic tricks or general approaches,... (more) |

| Question | — |
Estimating demand for challenge types Most challenges are code golf. Apart from being the name of the community, code golf is also easier to write both answers and challenges for (while a lot of time and effort can go into golfing, writing a valid answer is generally quick, and measuring its score is trivial). All of my challenges so far... (more) |

A: Should we delete the code-golf-tips tag? Yes, it has already been decided There was discussion of this previously in [Should [code-golf-tips] be replaced with [tips] + [code-golf]?](https://codegolf.codidact.com/posts/283176) and there is clear consensus there that the preferred tag usage should be separate [tips] and [code-golf]. The... (more) |

While I was writing that, the challenge rules were updated, which I think now excludes use of `τ`. (more) |

| Comment | Post #293752 |
There's a [comment thread](https://codegolf.codidact.com/comments/thread/10711#comment-26764) that gives a different impression of the rules than the challenge specification, so I've asked for the challenge to be updated to remove any ambiguity.
Until that's done, I'm not certain whether `τ` is pe... (more) |

Ambiguity is common when designing challenge specifications. For this reason I post my challenges first to the [Sandbox category](https://codegolf.codidact.com/categories/50) so as much ambiguity as possible can be pointed out before answers start arriving. This makes it easier to make changes to the... (more) |

The challenge says:
> No built-in hexadecimal functions.
However, this comment thread suggests a stronger rule:
> `.toString(16)` would be banned.
Since `toString` can convert to different bases depending on that argument, this suggests general base conversion functions are banned.

A: Rust golfing tips Replace `reduce` with `fold` Unlike some languages, Rust's reduce returns an `Option`, requiring additional bytes to `unwrap` the output. However, Rust's fold does not. If you can find a suitable neutral initial value that will keep your output the same (such as the additive identity `0` for a ... (more) |

A: Rust golfing tips Avoid assignment & semicolon of unnamed closure Closure (15 bytes) If you need to call a closure using it's name (such as if it is recursive) then you need the bytes required to assign it to a variable, including a trailing semicolon to end the assignment. ```rust let f=|a,b|ab; ``` Tes...

We have questions tagged "tips" and "code-golf", and we also have questions tagged "tips" and "fastest-code" or "tips" and "king-of-the-hill".
Does this work well enough, or is there demand for "fastest-code-tips" and "king-of-the-hill-tips"? I was guessing the separate tags for "tips" and the cha... (more) |
