Over the past 21 months I’ve written a code editor from the ground up, including: a fast (~120fps) canvas-based editor component; multi-language syntax highlighting with Tree-sitter; snippets; a file browser; find-and-replace with regex and JavaScript expression support; and two completely new features: AST mode and…
There is something legendary and historic happening in software engineering, right now as we speak, and yet most of you don't realize at all how big it is.
Imagine if you could auto scale simply by wrapping any existing app code in a function and have that block of code run in a temporary copy of your app
The title oversells the content a bit 1 1: Some called it disingenous dickish clickbait. I don't disagree ;-) :
A fully-regulated, API-driven bank built with Clojure, enabling fintech companies to integrate banking features quickly and securely
"I learned Zig in a weekend! …Six hours! …6µs!" say the blissful lizards. Followed by something to the effect of, "It’s easy to pick up because the syntax is so simple."

In 2007, a small team at Yahoo! briefly changed how we program the internet. This is their story.
I was going through the release notes of the new Python 3.12 version the other day, and one item caught my attention in the deprecations section:datetime.datetime’s utcnow() and utcfromtimestamp()…
It’s well-known at this point that GPT-4/GPT-3.5-turbo is non-deterministic, even at temperature=0.0. This is an odd behavior if you’re used to dense decoder-only models, where temp=0 should imply greedy sampling which should imply full determinism, because the logits for the next token should be a pure function of…
In distributed systems, logical clocks play a key role in the ordering of system events. What are the various logical clock designs, and how do they help with event ordering? This article answers these questions.
Companies see huge server savings with Elixir.
Can’t Be Fucked Aussie slang for not wanting to, or not having the energy and motivation to do something. “Man, i really can’t be fucked changing the channel, let’s just watch Springer.” - Urban Dictionary
Updated performance, developer experience, and site
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata , which exposes much of the regex crate internals as their own APIs for…
Developers can now bring their own data to customize GPT-3.5 Turbo for their use cases.
A collection of specific ways to improve your use of Rust
Three years, two states, and one pandemic ago, I wrote about a very weird idea: what if the type system could track which data existed before a pure call, to eliminate its memory safety overhead? 0
This is a post about strong static typing, why I feel strongly about the topic, and some of the ways we utilize the Rust type system at Svix.

Buck2, our new open source, large-scale build system, is now available on GitHub. Buck2 is an extensible and performant build system written in Rust and designed to make your build experience faste…
I don’t know what you were doing on 25th of December 2022. I was eating pierogis, while Ruby team did some epic sh***!
Update: I gave a talk on this topic at P99 CONF 2023 and at PyCon IL 2024 (Hebrew). A while ago at $work, we had a performance issue with one of our core Python …
Git users are encouraged to upgrade to the latest version, especially if they use `git archive`, work in untrusted repositories, or use Git GUI on Windows.
CHM publicly releases the source code to Apple's Lisa computer, including its system and applications software.
Go 1.21 expands Go's commitment to backward compatibility, so that every new Go toolchain is the best possible implementation of older toolchain semantics as well.
