A formal specification would be basically useless, if nothing guarantees that the reference implementation actually follows it. Sharing & contributing to the same test suite is a much more practical approach.

There is the #[must_use] attribute for function return values, which throws compiler warnings when results are unused. It is not a real part of the type system though, but it serves as a useful lint.

As a practical example Rust uses a less powerful version of linear types called affine types for its ownership system. Values are moved by default in assignments and function calls, and they cannot be used (in their original location) after

Rust is fairly nice to use for scripting / high level programming tasks. Libraries tend to be of high quality, and typically well (and consistently) documented. Ownership and borrow checking does not tend to cause issues in pipeline-li

WASM was explicitly designed to be easy to into native code. No production-ready WASM runtime is interpreting bytecode in hot code paths.

It's an excellent talk, but IIRC the point was that hypothetical Metal language was still a subset of JavaScript. From the technology point of view WebAssembly has basically nothing to do with JavaScript, except that both are part of t

Rust has a pretty strict backwards compatibility policy. Generally speaking breaking changes are not allowed, unless they fix a specific vulnerability or other critical issue. Language-level breaking changes can be done with the Edition mec

IMHO most of the time it's better to create a special 2-case enum for your specific use case. It's 3 lines of code, which gives you significantly clearer naming than "Either" and "Left/Right".

I do not disagree with that at all! I played Minecraft for the first time before it even had multiplayer, and I'm currently running a survival server for my friends. I think it's a great game for people of all ages, I just don&#x2

Redstone is absolutely miserable to use. Even the simple task of moving signal around is a chore. Even though it can be used to do anything with the magic of NOR gates and Turing completeness, it is an outright hostile environment for learn

I think most open world AAA games have done this for over a decade. They either vary a base face model randomly, or mix from hundreds of variants, hairstyles, clothing options, accessories etc. Literally no one is making 400 unique models f

It's not just a texture pack in any way - just read the dev blog. They are also overhauling all of the UIs, adding mouse support to everything and so on.

You can easily split stuff into modules without getting classes involved. For example the `Math` module which has been in JS basically forever.

I'm sure NVidia is fine, as they are the market leader in gaming / workstation hardware accelerated RT.

Of all the bad solutions, Zoom is the best one. It is the only one with a native (= not a glorified web browser) client, which you can definitely feel. Both Slack's and Teams' calls bring my top-end (Intel) MBP to its knees, while

Rust is normally always compiled directly to Assembly using LLVM. The only exception is mrustc [0], which is only intended to be used for bootstrapping a Rust compiler with a C++ compiler. It produces "very ugly C". [0] https:&#x

If you are using TypeScript (which you should), undefined is not inherently any more dangerous or unpredictable than any other form of encoding missing values.

Of course undefined is safe. It is just a different kind of null, and nothing else.

An experienced C++ programmer can learn Rust quite easily. The hard part (ownership & lifetimes) is what experienced C++ developers should already know by heart, but the primary difference is that the compiler enforces the same rules.

Of course. I'm well aware of Quake's impact, legacy and the competition at the time.
