A half-hour to learn Rust
In order to increase fluency in a programming language, one has to read a lot of it. But how can you read a lot of it if you don’t know what it means? In this article, instead of focusing on one or...

The HTTP crash course nobody asked for
HTTP does a pretty good job staying out of everyone’s way. If you’re reading this article, there’s a solid chance it was delivered to you over HTTP. Even if you’re reading this from an RSS reader o...

Lies we tell ourselves to keep using Golang
In the two years since I’ve posted I want off Mr Golang’s Wild Ride, it’s made the rounds time and time again, on Reddit, on Lobste.rs, on HackerNews, and elsewhere. And every time, it elicits the ...

I Want Off Mr. Golang's Wild Ride
My honeymoon with the Go language is extremely over. This article is going to have a different tone from what I’ve been posting the past year - it’s a proper rant. And I always feel bad writing tho...

Understanding Rust futures by going way too deep
So! Rust futures! Easy peasy lemon squeezy. Until it’s not. So let’s do the easy thing, and then instead of waiting for the hard thing to sneak up on us, we’ll go for it intentionally. That’s all-a...

I won free load testing
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 th...

What's in a Linux Executable?
Executables have been fascinating to me ever since I discovered, as a kid, that they were just files. If you renamed a .exe to something else, you could open it in notepad! And if you renamed somet...

Some mistakes Rust doesn't catch
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 l...

Why is my Rust build so slow?
I’ve recently come back to an older project of mine (that powers this website), and as I did some maintenance work: upgrade to newer crates, upgrade to a newer rustc, I noticed that my build was ta...

Just paying Figma because nothing else works
My family wasn’t poor by any stretch of the imagination, but I was raised to avoid spending money whenever possible. I was also taught “it’s a poor craftsman that blames their tools”, which apparen...

A terminal case of Linux
Has this ever happened to you? You want to look at a JSON file in your terminal, so you pipe it into jq so you can look at it with colors and stuff. That’s a useless use of cat. …oh hey cool bear....

The bottom emoji breaks rust-analyzer
Some bugs are merely fun. Others are simply delicious! Today’s pick is the latter. Reproducing the issue, part 1 (It may be tempting to skip that section, but reproducing an issue is an important p...

Small Strings in Rust: smolstr vs. smartstring (2020)
Hey everyone! This article is brought to you by a shameless nerd snipe, courtesy of Pascal. In case you’ve blocked Twitter for your own good, this reads: There should be a post explaining and compa...

What's in the Box?
Here’s a sentence I find myself saying several times a week: …or we could just box it. There’s two remarkable things about this sentence. The first, is that the advice is very rarely heeded, and in...

When rustc explodes
One could say I have a bit of an obsession with build times. I believe having a “tight feedback loop” is extremely valuable: when I work on a large codebase, I want to be able to make small increme...

Crates.io phishing attempt
Earlier this week, an npm supply chain attack. It’s turn for crates.io, the main public repository for Rust crates (packages). The phishing e-mail looks like this: And it leads to a GitHub login pa...

Request Coalescing in Async Rust
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!...

My ideal Rust workflow
Writing Rust is pretty neat. But you know what’s even neater? Continuously testing Rust, releasing Rust, and eventually, shipping Rust to production. And for that, we want more than plug-in for a c...

My Gift to the Rustdoc Team
About two weeks ago I entered a discussion with the docs.rs team about, basically, why we have to look at this: When we could be looking at this: And of course, as always, there are reasons why thi...

A Rust match made in hell
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 S...

Migrating from Warp to Axum
Falling out of love with warp Back when I wrote this codebase, warp was the best / only alternative for something relatively high-level on top of hyper. I was never super fond of warp’s model — it’...
