If you maintain an open-source project in the range of 10k-200k lines of code, I strongly encourage you to add an ARCHITECTURE document next to README and CONTRIBUTING. Before going into the details of why and how, I want to emphasize that this is not another docs are good, write more docs advice. I am pretty sloppy…
(at least on commodity desktop Linux with stock settings)
It's common knowledge that Rust code is slow to compile. But I have a strong gut feeling that most Rust code out there compiles much slower than it could.
There's a fascinating Rust library, loom, which can be used to thoroughly test lock-free data structures. I always wanted to learn how it works. I still do! But recently I accidentally implemented a small toy which, I think, contains some of the loom's ideas, and it seems worthwhile to write about that. The goal here…
One of my favorite blog posts about Rust is Things Rust Shipped Without by Graydon Hoare. To me, footguns that don't exist in a language are usually more important than expressiveness. In this slightly philosophical essay, I want to tell about a missing Rust feature I especially like: constructors.
std.Io.Threaded is one of the implementations of Zig's new Io interface that enables concurrency. This is a boring just use threads impl. I personally find it neat though --- it does this weird thing that I wanted to do for ages, that to my knowledge no one else is doing properly, and implements it better than I…
These are my notes after learning the Paxos algorithm. The primary goal here is to sharpen my own understanding of the algorithm, but maybe someone will find this explanation of Paxos useful! This post assumes fluency with mathematical notation.
How long should a micro benchmark run? My rule of thumb is to tweak the input size until the benchmark takes about 300ms, for the following reasons:
In reply to this email:
More or less the title this time, but first, a story about SIMD. There are three levels of understanding how SIMD works (well, at least I am level 3 at the moment):
