Option 4 is effectively treating environment variables the same way as flags and compiler options, but I'm not entirely comfortable with that existing default rule either. Flags and compile-time options can also be used to fine tune the language to the challenge.
I might be convinced by an answer ... (more) |

That's a good point about obscure rules.
I added the `hash` function to my answer, and then realised it wouldn't work without setting an environment variable, and then assumed that the correct course of action would be to add the bytes to the score, but that felt unfair on the other Python answer,... (more) |

I'm not sure if our current [default rules](https://codegolf.codidact.com/categories/48/tags/5434) cover this, so I've raised on Meta [Using environment variables in code golf](https://codegolf.codidact.com/posts/294072) if you'd like to discuss how this should be treated. (more) |

| Question | — |
Using environment variables in code golf I wrote a code golf answer which depends on setting an environment variable before running the code. I've assumed that the bytes used to define the environment variable should be added to the score, but I'm not sure if this is covered by existing default rules. Should setting environment variables... (more) |

A: Net or not? Python 3 + PYTHONHASHSEED=764, 193+18=211 bytes This doesn't work with Python's default settings, because for security reasons `hash` gives different results for the same input on different runs. It needs 18 extra bytes to define an environment variable to make Python give consistent output, to allo... (more) |

I used your approach to write a Rust answer (thank you!). Thinking of your probable improvement 1, I've omitted the longest encodings from the long string by taking the transpose of the input and only keeping whichever is shorter (the encoding before or after transposing). This means the longer of ea... (more) |

Sounds promising.
Yes there's probably still plenty to reduce. I also considered rearranging the numbers so some have an overlap between the end of one and the beginning of the next, so the duplicated overlap can be omitted to save bytes, but that wouldn't be as quick to find as just losing the sp... (more) |

My other thread about removing spaces saves more than this approach, so it's probably redundant now. The spaces can't be removed in the same way here, so this might be a dead end. (more) |

| Comment | Post #294030 |
Since the order of the numbers in the string is not important, they can be rearranged into an order which does not cause the problem for any of the spaces, allowing all of them to be removed:
```python
lambda s:hex(sum(2**i*(c=='#')for i,c in enumerate(s)))[2:]in"c08182c0c102c30cc702c704c708e07e0... (more) |

| Comment | Post #294030 |
The spaces in the long string of true cases can't all be removed, because that would sometimes cause the end of one number and the beginning of the next to join together and make one of the false cases present in the string, causing a test case failure.
However, this problem only affects 6 of the ... (more) |

There's a way to save 4 bytes but it will make the code break after the first time it is called. I don't think we have a rule on this yet, so I've raised on Meta [Answers that work only once](https://codegolf.codidact.com/posts/294031) to see what the community thinks.

Turns out it's still possible to save some bytes by converting the string of base 36 numbers to a list of integers, and checking if the integer you generate is in that list:
```python
lambda s:sum(2**i*(c=='#')for i,c in enumerate(s))in list(map(lambda x:int(x,36),"4h3if6 1f9o 1fyb 1g1t 1g1u 1g1w... (more) |

Oh wait - Python only converts *from* base 36, not to base 36. Might not be any saving after all. (more) |

You can save some bytes by using base 36 instead of base 16. (more) |

The leaderboard turns out to not be equipped to handle scores less than 1, so your answer is currently showing as "Invalid entry format" despite you including a correctly formatted (albeit empty...) codeblock.

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 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.
