Ah, Hyperbolica. I just wish it had more going for it. It feels a lot like the sort of cute educational tech-demo game which you'd show school children/teenagers if you (for whatever reason) wanted to teach them about hyperbolic g

Saying that the determinant is useless to determine whether a matrix is incorrect, or misleading at best. This is purely a matter of numerical stability. Of course [[1e-10, 0], [0, 1e-10]] is nonsingular, and its determinant is 1e-20, which

Rust does it pretty well. No error handling via exceptions, it's all Result<Ok, Err> or Option<Value> types. This is great since it's enforced on a type-level that every result or option has to be unwrapped before it c

I'm going to be pedantic here, but this merely means that Go can't fill Zig's niche. Zig can (in a lot of situations) presumably easily fill Go's role. Both languages have a focus on simplicity and explicit syntax. In ot

Personally, I found "Writing an Interpreter in Go" better than "Crafting Interpreters". It has a follow-up book titled "Writing a Compiler in Go", which (similar to Crafting Interpreter's second half) impl

Can't say much about async, since I really lack the experience to say whether async in Rust could feasibly and realistically be much better than it currently is. Some people say that it'd be great if it worked as effortlessly as i

Will Rust keep growing? Yes, I think so. Will it turn into a C++-like monster? I don't know. Maybe, but when it comes to C++ it always feels like its "monster" status is largely a result of previous mistakes or early design d

Afaik Zig has the issue that basically everything happens on the Discord server, where it can't be indexed via search engines, or found by anyone who wants to have a quick question answered. This would be "fine" if the standa

I am not much of a Zig-head, but the best compromise I can think of is having a few operators which purely and solely exist for this purpose. In other words, there is no operator overloading, but you can define, say, "#+" for any

I think they were making a joke, namely that it looks like an arrow, even though it's presumably supposed to look like an envelope. The fact that we're talking about it shows that this is in fact a minor(?) design flaw. Ideally

by TwentyPosts 3y ago
It's okay? I think what bothers me the most about it is that the envelope is smaller, and not front and center anymore. I get that the idea was to make it look more like the Firefox logo, and it succeeds in that regard, but I liked tha

Mojo bothers offers Just-In-Time and Ahead-Of-Time models. Proper AOT compilation is going to offer a significant speedup, but probably not enough to get to their stated goals. And good luck carrying all of Python's dynamic features ac

Somehow I'm still skeptical! Feels like "strict superset of Python, all Python code works" and "several orders of magnitude faster" just sounds like you're trying to have your cake and eat it, too. I doubt that

A cynical view is that 80% of Go's success is a result of the excellent tooling, and the fact that it's associated for and pushed by Google, while the underlying language is "mediocre" at best. In theory I agree with Go&

What are some of these pitfalls in C++'s const design? I assume the issue is that it's difficult to guarantee const correctness as long as you have the ability to fiddle with pointers? Function signatures showing when a parameter

I'm not. I'm a new user, and I notice that Duolingo kind of sucks, but I am getting some amount of value out of it. I'm very open to suggestions for better language learning apps, though.

As someone who didn't like the idea of learning a language at all but has to, I'm glad that Duolingo gave me a very, very easy way to get started with literally anything at all. It's simple and streamlined, meaning that it&

This is also what I'd call the classic issue with Duolingo. Or rather, one of them, considering that the app has all sorts of issues. If you use nothing but Duolingo you'll plateau very quickly. It's probably "okay"

Go has no way to ensure "const correctness". If you pass around a slice (which you'll be doing a lot, since it's essentially Go's equivalent of a vector), everyone can modify the slice however they please. It's
