Rust has a combo: people come for safety, stay for usability. Languages struggle to win on usability alone, because outside of passion projects it's really hard to justify a rewrite of working software to get the same product, only wit

Unicode wanted ability to losslessly roundtrip every other encoding, in order to be easy to partially adopt in a world where other encodings were still in use. It merged a bunch of different incomplete encodings that used competing approach

It's quite the opposite. The number of high-quality maintained libraries is growing . Rust keeps growing exponentially, but by Sturgeon's law for every one surviving library you're always going to have 9 crap projects that a

High-throughput transit isn't there to be better in 1:1 comparison with one person's car trip, but to make better cities possible. If you only imagine this as a static scenario where everything is the same except you swap car for

I didn't think LLM's sycophancy would work on me. And yet, I've realized that a few research and brainstorming sessions with LLMs I thought were really good and insightful were just the LLM playing "yes and" improv

There's hardly any Rust in there. It's shelling out to the git command. This could have been a couple lines of bash. Actually doing this in Rust with lower-level libraries like gix would have been interesting.

Value of TSLA has been disconnected from the actual car business for a while, and instead vaguely betting on Musk figuring out something with robots, taxis, or AI or whatever. Now I wonder if it's tied to any future of the company at a

I've meant you don't need to worry about motors failing in old EVs, unlike engines that are the primarily concern in old ICE cars. Apart from battery degradation, the other thing that may be the final nail in the coffin for an old

I don't think you'll find anything much better than basis universal, assuming you want textures compressed on the GPU and the simplicity of shipping one file that decodes quickly enough. I've followed development of the encod

EV motors typically outlive the rest of the car. Leaf is old enough that there's a whole cottage industry of battery repairs, replacements, and repurposing them for solar energy storage.

The absolutely worst efficiency I've experienced was 2.7km/kWh at 120km/h in DS3 e-tense. That was a v1 Stellantis drivetrain, without a heat pump. Peugeot e208, Corsa-e, etc. are the same thing. Stellantis sucks at EVs, espe

It depends where your contributors are coming from. For example for Rust, the crates index is the discovery mechanism. Contributors will come to your repo by whatever link you put in your package's metadata. I've split my Rust pac

You won't reach the limits of weight and handling of EVs when driving on public roads in ways that don't risk jail time. Most people don't take their old Toyota to a race track, so they don't need their Leaf to beat a La

It gets exponentially better with bigger adoption, because chargers being in use pay for installation of more chargers (and batteries got cheaper, so charging stations have their own storage and are less limited by the size of their grid

Borrowing isn't for mutability, but for memory management and limiting data access to a static scope. It just happens that there's an easy syntax for borrowing as shared or exclusive at the same time. Owned objects are exclusively

Those who TL;DRd - it's for the factory, not the cars! Old EV batteries are great for energy storage. A worse weight-to-capacity ratio doesn't matter for batteries sitting on the ground. A battery that holds only 70% of its origin

To a large extent yes, but Rust adds more dimensions to the type system: ownership, shared vs exclusive access, thread safety, mutually-exclusive fields (sum types). Ownership/borrowing clarifies whether function arguments are given on

You can implement this in Rust. It's an equivalent of Rc<Cell<(Option<Box<T>>, Option<Box<T>>)>>, but with the Rc replaced by a custom shared type that avoids keeping refcount by having max 2 owners.

This can be done with exclusively owned objects. That's how io_uring abstractions work in Rust – you give your (heap allocated) buffer to a buffer pool, and get it back when the operation is done. &mut references are exclusive and
