This might have promise. I'd really like to see an example with a heterogeneous "select" construct, which is where a lot of these proposals fall down. Go lets users do this only over channels, so the rest of the ecosystem has

> Channels are specifically designed to be a high-speed data bus between goroutines, rather than ever use more expensive and less safe shared memory. What do you mean? How do you think channels are implemented? Go is open source, you can

Given this fork still boasts a 2-clause BSD license, the corporate nginx can still make the effort to backport patches. It's certainly harder than requiring a single converged development branch, but how closely they track Maxim's

I find that combining context and errgroup, with due care, lets us approximate Structured Concurrency to great benefit. I just think more care is due than most people give. When a function returns, we should be able to trust that any gorout

Sigh. People don't even know what bikeshed means any more. https://en.wiktionary.org/wiki/bikeshedding If you think the differences between C++ and Rust are "unimportant but easy-to-grasp issues" then yo

The only sets of arguments I use to git log regularly: * `git log branch` because I want to cherrypick or checkout parts of another branch. * `git log --stat` because what files changed can be a big clue for what I'm looking for. * `gi

A complementary virtue is that the commit is tightly scoped to exactly one change. I still see most engineers commit whatever they had in their working directory as a sort of blanket Save Point, without any thought to how those changes can

The US market in particular seems to be the worst in decades, but I'm not seeing the same in other markets. Friends in Australia hopped around in the last couple of years and are very happy with their conditions and total comp. It does

Rust enums are incrementing too so that they can generate machine code with dense jump tables. If you also want the discriminant value for something, you opt into that with e.g. #[repr(u8)] and you can even override the values. Note that un

You've highlighted a difference in rewrites I think is worth recognizing. urllib -> requests & urllib3 is an example of a rewrite that does not preserve the original interface, which means it can fix more things but it has to co

Exactly, this is perfectly put and something I've hit several times myself. I have learned to do the exact opposite: sprint to structure the project just enough to begin to tackle the hairy stuff as soon as possible, so that any change

I think it was both, because I think it also worked even when it wasn't a search domain. Can anyone still at Google check?

I've pulled off several large, successful rewrites so I'm going to respectfully disagree, even though I agree I have seen exactly the failed rewrites that would motivate someone to ban rewrites. The crux of my argument is that som

This is exactly how a committee would design it if none of the participants had actually used an internal domain. For example, in Google, https://go/foo had "go" as technically a TLD, and the memorable suffix that

I know what you mean but it's not that simple. The ecosystem clearly depends on the language in a very real way. If Zig changed enough to be a deal breaker for Bun, or even stopped being maintained at all, then Bun is stranded until th

Rust does keep track of where the object is alive and in scope, even if that happens to be decided dynamically, e.g. an object may only exist in a condition branch or as the result of a loop running at least once. Objects also won't be

I don't recommend choosing technologies this way. Elm is one of many recent, prominent examples of how years of promising language work can still leave production users stranded, both with backwards-incompatible changes that are deal-b

How? GraphQL is just another way to make query API with structured output, almost always JSON in practice. If you wanted server-side rendering, you still need another endpoint even if it happens to use GraphQL internally, just like you coul

I've seen far worse crimes than that :) Example: Writing what is effectively a graph algorithm where every edge/node lookup is a string key in a hash map. Transforming the string keys into dense integer offsets once-off costs near

My problem is that people use this as an excuse not to consider optimization at all initially, because they think that once they have a working version, they can "just" profile and optimize the slowest few functions to get ideal p

Not sure if this is a spooky coincidence, but I happened to be reading the Rust 1.75.0 release notes today and fell into this 50-tab rabbit hole: https://github.com/rust-lang/rust/pull/113053/

Have you found F# jobs more abundant than Rust jobs? We might be in different bubbles. I know F# has been around much longer and is a first-class citizen in Microsoft's ecosystem, but I don't touch that ecosystem much. Shame, too,

This only gets you so far. In today's software landscape, somebody is going to want to hit a HTTP JSON API to automate something in their second week, and they'll have a really rough time with how async Rust works today. Try expla

I completely agree but do feel it needs qualifying. The problems beginners run into aren't usually the same as the problems experienced devs run into when adopting a language new to them, but where I see the two overlap I know somethin
