Why you might want a remote dev environment
Fearmongering aside — and Cthulhu knows there's been a bunch, since — there's a bunch of reasons to want a remote dev environment.

It happened when I least expected it.
Someone, somewhere (above me, presumably) made a decision. "From now on", they declared, "all our new stuff must be written in Rust".
I'm not sure where they got that idea from. Maybe they've been reading propaganda. Maybe they fell prey to some confident asshole, and convinced themselves that Rust was answer to their problems.

I've been building up to this article for a few months now!
This is peak "the kind of content I started writing seriously for". In a time where you can do a lot of useful things in life just by swiping on a mobile device, I think it's even more important to understand what's going on inside these devices.
And not just for experts, for whom it's their day job, but for everyone who's curious enough. This is my attempt at making all of that a little less scary.

Long story short: a couple of my articles got really popular on a bunch of sites, and someone, somewhere, went "well, let's see how much traffic that smart-ass can handle", and suddenly I was on the receiving end of a couple DDoS attacks.
It really doesn't matter what the articles were about — the attack is certainly not representative of how folks on either side of any number of debates generally behave.

Up until recently, hyper was my favorite Rust HTTP framework. It's low-level, but that gives you a lot of control over what happens.
Here's what a sample hyper application would look like:
$ cargo new nostalgia
Created binary (application) `nostalgia` package
$ cd nostalgia
$ cargo add hyper@0.14 --features "http1 tcp server"
Updating 'https://github.com/rust-lang/crates.io-index' index
Adding hyper v0.14 to dependencies with features: ["http1", "tcp", "server"]
$ cargo add tokio@1 --features "full"
Updating 'https://github.com/rust-lang/crates.io-index' index
Adding tokio v1 to dependencies with features: ["full"]

As the popular saying goes, there are only two hard problems in computer science: caching, off-by-one errors, and getting a Rust job that isn't cryptocurrency-related.
Today, we'll discuss caching! Or rather, we'll discuss... "request coalescing", or "request deduplication", or "single-flighting" - there's many names for that concept, which we'll get into fairly soon.

I often write pieces that showcase how well Rust can work for you, and how it can let you build powerful abstractions, and prevents you from making a bunch of mistakes.
If you read something like Some mistakes Rust doesn't catch in isolation, it could seem as if I had only nice things to say about Rust, and it's a perfect little fantasy land where nothing ever goes wrong.

I still get excited about programming languages. But these days, it's not so much because of what they let me do, but rather what they don't let me do.
Ultimately, what you can with a programming language is seldom limited by the language itself: there's nothing you can do in C++ that you can't do in C, given infinite time.
As long as a language is turing-complete and compiles down to assembly, no matter the interface, it's the same machine you're talking to. You're limited by... what your hardware can do, how much memory it has (and how fast it is), what kind of peripherals are plugged into it, and so on.
