> Why is f.x a const object even when accessed through a non-const variable? Because the member is const. It's a bit strange example because there's no reason to have mutable pointer to a struct with only const members. A bette

What do you disagree with? CAP has a long history and was originally provided without a proof. The proved version of CAP has a very strict definition, but it's not that useful in practice because most systems don't actually foll

This might be a bit confusing, but "consistency" in CAP doesn't have one "strict" definition. It can be roughly defined as "a request will either return the correct response or return an error", but you&

This would be a “bijective function” or a “perfect hash function”, although the latter is usually used when the input is much smaller than the output.

As someone who has actually studied physics (including quantum mechanics) I find this analogy extremely poor. Keeping multiple potential candidates which you gradually reduce into a single solution is a very common approach for solving a va

I read through the paper when the first draft was published on Arxiv a few weeks ago. It's a very neat algorithm and there seems to be a cool underlying concept here, but I wasn't quite able to make it practical. This algorithm re

Historically there’s been a mentality on HN to avoid these repetitive shallow jokes (sorry, but it’s true) since they don’t lead to much interesting discussions, but maybe times are changing.

I like (and actively use) code formatters, but honestly I don't understand why people make such a big fuss about its impact. Weirdly formatted code impacts maybe 1% of my "reading code"-ability — at least after I accept &quot

It’s not “wrong”, but it’s annoying. They’re asking me to invest into their platform, but they’re also constantly increasing the price and/or making it more restrictive. This makes it hard for me to understand the long term cost of a c

Zig uses explicit allocations everywhere (if you want to allocate something you need a reference to an allocator) which is pretty unique even for low-level languages (e.g. C, Rust)

It should be mentioned that their reasons were mainly developer convenience/productivity, and not “correctness”. I think people severely overrate the value of the language when it comes to avoiding bugs. We already know how to minimize

I’ll have to admit that I don’t fully know how these things work, but my impression was that a malloc(4GB) on most systems will not actually allocate 4GB, but only acquire virtual memory and the OS will give it memory when it’s being used.

How does this compare to just calling .reserve(4GB) on a regular std::vector?

Well, it seems like most of the critical packages in the Rust ecosystem are at 0.x so I’m not sure how much this is being done in practice.

I was actually thinking about writing a “macro” (i.e. function) which takes in a math expressions as a string and an anonymous struct for these use cases: eval("Ax + v", {.A = …, .x = …, v = …}) Wouldn’t that be cool?
