I'm not against having some kind of service that users can install and enable for telemetry using these metrics, but metrics would be useful even if we never do anything like that and they only ever exist on the users' machine: &q

The GP is referencing cases where inference can't figure out what the T is in Option::<T>::None. This can happen in the body of a closure without an explicit return type, for example. To solve it you have to specify the type eith

Without implying whether one position or the other is stronger, I want to point out that even when you're on a wide screen it's not uncommon to take advantage of that and have at least two screens side by side.

Bugs like that in a production compiler could be worrying. In a compiler for a language still being defined, not so much. Compare Rust 1.0 vs 1.71 to see how much of a gulf there is between "first stable release" and "compile

If you see poor behavior in the project, call it out. I would personally be interested in being made aware of it to help eliminate it, but the moderation team[1] exists specifically to deal with this. 1: https://www.rust-lang.org

But that is not an immutable fact of life. It's not "cultural" either. I see the main reason there aren't grocery stores on every other corner to be single family zoning. Not wanting to have "noise" around your

How does making cities more amenable to alternative modes of transportation affect people that neither lives nor works in those cities in any way?

For reference, my commute within SF used to take me 45 minutes due to traffic by car. On my bike it was 50. Include finding parking and it was a wash. By bus+wall it took about the same. I didn't drive. If the bus was faster (because i

In dense cities, there are multiple grocery stores withing walking distance. What people do is come back from the office (or anywhere else), get off the subway or bus, and on the 2 block walk home pop into the shop for fresh produce. Yes pe

Does that math include repairs, gas, insurance, etc? The average monthly cost of owning a car in California is ~$500. It also sounds like you might be an outlier, the average used car cost is much higher than that[2], let alone new[3]. It&#

What I noticed is that you have a lot of tools available to tune Java applications, but it was more necessary to rely on them to get to a good spot. In the Rust version, I got a 2x speed improvement by using a rayon thread pool instead of

They both boiled down to a sendfile call, effectively. The differences came to runtime weight, and parallelism strategy/implementation. It turns out that not having to pay for object headers/stack allocation by default, helps a lo

I would assume debugger support. Rust is in a tough spot because a lot of code gets compiled away, and debuggers need to understand some Rust-isms for good experience, like enum support. I don't think this is an insurmountable situatio

Fighting the urge to debug, and failing, are they running the same software? I could see it being a hardware issue, but highly doubt it. For me it works flawlessly with an old T460 and its dock, but maybe the USB-C codepath is less robust,

Without trying to sound dismissive, Rust is production ready today, Carbon isn't. Even if Carbon was significantly better, that alone accounts for the adoption of Rust and not Carbon today.
