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 the _input_, which is always a single chara

> You can ease the cognitive load by making certain programming structures first-class citizens in the language. Which, in every s-expression based language I'm aware of, can be achieved using macros.

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 allow this, but this is not a priori obvious - Java manages sim

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, it's a complete hindrance. It's the singl

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 otherwise (D uses parentheses) As for the

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.

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. Driving safely in all conditions without aid from a human

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 absolutely nothing to do with its syntax.

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 logs.gz | vim -' opens the file pretty quickly i

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, Reddit, etc. like "IANAL", so as to put forw

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?

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 bigint type or equivalent). When its not, its just a higher

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 didnt seem like a massive leap forward to m

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. Kernels of ring homomorphisms are ideals, which in general

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

Considering that Windows 95 powered many people's first exposure to computers, they clearly had to put a lot of thought into user experience. And they did a fantastic job. I definitely believe almost everything since has been "inn
