A common rule here on PPCG is that programming languages invented after a challenge was posted cannot be used to answer that challenge. (I've had trouble finding a specific meta post that addresses ...

This is a follow up to Can I ever answer with a language invented after the challenge was posted? It seems to be well established that you can post answers using a new language, but you can't win. ...

Sometimes there are bugs in interpreters that make them unable to run programs that are valid by the specification of the language, or make them work incorrectly. This will break programs using those ...

I was hoping to answer a question using a particular cellular automaton that was defined 17 years ago (before the question was asked) but for which I am unable to find a free interpreter on the ...

There are a number of standard loopholes which experienced question-setters seek to explicitly close. However, inexperienced question-setters may unintentionally leave them open, or respondents may ...

Take this recent challenge for example. There are many languages where the shortest solution is simply *. Likewise, for other trivial challenges, the same 1-byte ...

I've been thinking about command line flags for a while, and I think that we should stop adding them to our byte counts. And instead consider different invocations to be different languages. Now ...

The community has decided that answers in newer languages can now compete in code-golf (they were previously required to be marked as non-competing). However, now and then I will still come across an ...

Related. Earlier today, AdmBorkBork posted this question on TNB, asking whether or not PPCG was dying. In the following discussion, I have suggested we, as a community, could start "reviving" (for ...

The Library of Babel is a huge library with many books. For example, the book titled ",fkwpival.vbfz" defines code golf on page 29 code golf is a type of recreational computer programming ...

Although we have consensus on the Definitive policy about answers not meeting the challenge specification, it is aimed at answers rather than challenges. I had assumed that would imply that a ...

I recently created a simple little language that transpiles Brainfuck into a format that is half the size of its input. It can be used to compress and decompress Brainfuck programs. Provided I ...

According to this meta post we can never recreate old challenges. Of course not, its a duplicate. Makes sense to me. No problems. Except this challenge can no longer be answered with a language newer ...

A disadvantage of the "default rules as answers" is that the rules don't have a common, organizing, "formal" thought behind them. I'm talking about this one here. I understand it as applying to "...

I'm creating a programming language aimed at code golf puzzles. The language has an internal set of tapes, where the computations are saved and then retrieved to the user. At the end of the program, ...
