array.includes(x) is really a function includes(array, x), and this is O(n,1).

> And it hit me that it's actually O(n), because we've got an array and have to iterate over every element to see if the element matches char. No, it's actually O(1). n refers to t…

The major examples are parts of the stdlib which offer higher-level pipelines (some answers here indicate the need for such things to be very flexible in their return values to all…

One thing that really annoyed me about D is that its documentation lists basically every function with an 'auto' return type. Auto should be completely banned from documentation, i…

My personal anecdatal arguement against "Hard to parse for humans" is... I actually really like generics residing within . It's actually harder for me to read generics denoted othe…

Within my first year of professional development, I encountered several fixed-width files I needed to read and write. I suppose exposure depends a lot on the specific industry.

> I had to parse 9million lines. Awk would chew through that no problem. > Some of which contain "quoted records", others, same column, are unquoted. In which case, there is the FP…

Just want to throw D into the ring as a candidate here. It's a smashing language. I think it satisfies the very compromise you are seeking from your evaluations of other languages.…

I think I am going to side with VW on this. I have always been skeptical of fully autonomous vehicles, and I do not believe they will _ever_ exist on the roads that currently stand…

I think C has better syntax than Rust, by miles. Rust's syntax is the bastard child of C++ and OCaml and is more than the sum of its parts. Rust code having fewer bugs has absolute…

> disk space is mostly free these days. This is the only "argument" ever presented, and I don't think it is any good. I care about file sizes. I want to get the most out of my hard…

Here's one maybe-reason and one definitely-reason VSCode cannot replace vim for me: 1) Logs are often compressed. Can VSCode open .gz files? Vim behaves pleasingly unixy: 'zcat log…

I don't think it does. People share information and learn from each other. Hence, it is important to be responsible when providing information. We frequently see disclaimers on HN,…

Is it? If A says to B, "don't vaccinate your kids", B complies, and then B's child dies of a disease it could have been vaccinated against, you would not say A had any culpability?…

Would be a big improvement on Rust.

Money is not as wierd as anyone might guess. I work on a financial application, and money is almost always just a BigDecimal with the scale set to 2 (and stored in a database as a …

AlphaZero does not "smash" Stockfish. In official games they draw 90+% of the time, and stockfish won a non-negligible number of games. AZ is still the "winner" but honestly it did…

Interesting analogy, but it's a little off. The main reason modules are interesting is not as a generalisation of vector spaces, but because they are helpful in studying rings. Ker…

Great articles for when you want to know how it works but want the code to play hard to get.

Rust macros can do worse things than C macros can. They can execute arbitrary code at compile time.
