Programming languages are non-ambiguous, in the sense that there is no doubt what will be executed. It's deterministic. If the program crashes, you can't say "no but this line was a joke, you should have ignored it". You

The risk with that is that because it was not obvious to you does not necessarily mean it's not obvious to others. Over the years, I have seen many, many juniors wrapping simple CLI invocations in a script because they just learned abo

Literate programming is not about documenting the public API, it's about documenting the implementation details, right? Otherwise no need for a new name, it's just "API documentation". > if you need to e.g. make a qui

My understanding is that "literate programming" doesn't say "you should document the public API". It says "you should document the implementation details, because code is hard to understand". My opinion is

Again, if it's a comment saying "we need this hack because the hardware doesn't support anything", I don't call it "literate programming". Literate programming seems to be the idea that you should write pr

What do you mean by "poorly documented"? I have been using it for 20 years, I have yet to find something that is not documented. As for convoluted, I don't find it harder than the other build systems I use. Really the problem

I would call your example "bad code". Do you disagree with that?

IMHO, you shouldn't have to justify yourself ("yeah yeah, this is not optimal, I know it because I am not an idiot"). Just write your code in O(n) if that's good enough now. Later, a developer may see that it needs to be

Do you have an example of such knowledge that you need to get from the comments? I have been programming for 20 years, and I genuinely don't see that much code that is so complex that it needs comments. Not that it doesn't exist;

Agreed. Tests are documentation too. Tests are the "contract": "my code solves those issues. If you have to modify my tests, you have a different understanding than I had and should make sure it is what you want".

My point is that if your code is well written, it is self-documenting. Obviously Class1 and var2 are not self-documenting.

Difficult to say without an example, but "code isn't enough" is just one possible conclusion in this case. Another one could be that the code is not actually as good as expected, and another one is that the colleagues may nee

> JetBrains also wants to make Kotlin target every platform under the sun So did Scala long before. It's just that Kotlin got a lot more traction for different reasons.

I am not convinced. - Natural languages are ambiguous. That's the reason why we created programming languages. So the documentation around the code is generally ambiguous as well. Worse: it's not being executed, so it can get out

Well many times it does. bool isEven(number: Int) { return number % 2 == 0 } I would say this expresses the intent, no need for a comment saying "check if the number is even". Most of the code I read (at work) is not documented,

Well many languages are memory safe. Java has been memory safe forever. Rust is the one that is memory-safe with zero-cost abstractions, right?

How does it compare to Kotlin async? I find Kotlin generally hits a good balance across the board.

I denied the contacts permission to the Play Services. It just shows a notification when it tries to access them, which is actually not common at all.

My opinion is that trains are a natural monopoly, they should belong to the government. Fine if some trains go through it (e.g. a TGV between Paris and Berlin).
