Every so often I come across a paper, blog post, or (occasionally) video that completely changes how I think about a topic in programming languages and compilers. For some of these posts, I can’t even remember how I thought about the idea before reading it—it was that impactful.
All of a sudden, without any ostensible cause, Google Docs was flooded with errors. How it took me 2 days and a coworker to solve the hardest bug I ever debugged.
I see people make the same mistakes over and over again when learning Rust. Here are my thoughts (ordered by importance) on how you can ease the learning process. My goal is to help you save time and frustration. Let Your Guard Down Stop resisting. T…
Memory safety is all the rage these days. But what does the term even mean? That turns out to be harder to nail down than you may think. Typically, people use this term to refer to language...
A while back, Google DeepMind unveiled Gemini Diffusion, an experimental language model that generates text using diffusion. Unlike traditional GPT-style models …
Back in my day, we used math for autocomplete.

Initial kernel and subsystem support for new Snapdragon 8 Elite Gen 5 posted for review. Learn what’s in the patches and how you can start working with them.
This RFD describes futurelock : a type of deadlock where a resource owned by Future A is required for another Future B to proceed, while the Task responsible for both Futures is no longer polling A . Futurelock is a particularly subtle risk in writing asynchronous Rust.
We are launching two new plans designed to make AI coding faster and more accessible: Cerebras Code Pro ($50/month) and Code Max ($200/month). Both plans give you access to Qwen3-Coder , the world’s leading open-weight coding model—running at speeds of up to 2,000 tokens per second , with a 131k-token context window …
Since the early days of automatic computing we have had people that have felt it as a shortcoming that programming required the care and accuracy that is characteristic for the use of any formal symbolism. They blamed the mechanical slave for its strict obedience with which it carried out its given instructions, even…
A breakdown of Claude's memory implementation, how it differs from ChatGPT, and what these opposite approaches reveal about each company's philosophy.
GPS coordinates aren’t exact. Sensor readings have noise. User behavior is probabilistic. Yet we write code that pretends uncertainty doesn’t exist, forcing messy real-world data through clean Boolean logic.
If someone had told me a few months ago I’d be playing with .NET again after a 15+ years hiatus I probably would have laughed at this.1 Early on in my career I played with .NET and Java, and even though .NET had done some things better than Java (as it had the opportunity to learn from some early Java mistakes), I…

How a simple loop enables powerful AI assistants
GitHub Actions has a package manager that ignores decades of supply chain security best practices: no lockfile, no integrity verification, no transitive pinning
Why does Git's autocorrect wait 0.1s before executing a mistyped command? Let's dig in.
Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.
This post is a long form essay version of a talk about PyTorch internals, that I gave at the PyTorch NYC meetup on May 14, 2019.
I was watching Alex Petros’ talk and he has a slide in there titled “Incantations that make HTML work correctly”. This got me thinking about the basic snippets…
In the latest release of D2 (0.7.1), we introduce ASCII outputs.
When my son was born last April, I had ambitious learning plans for the upcoming 5w paternity leave. As you can imagine, with two kids, life quickly verified this plan 🙃. I did eventually start some projects. One of the goals (sounding rebellious in the current AI hype cycle) was to learn and use neovim for coding. As…

Learn how to clone PostgreSQL databases instantly using reflinks. Turn slow template copies into milliseconds with PostgreSQL 18's new file copy options.
Andrew Kelley famously (or infamously, depending on your views) said "the compiler is too damn slow, that's why we have bugs." 1
How to test for leap years (until year 102499) in the proleptic Gregorian calendar with just three 32-bit instructions, with detailed explanation of the bit-level tricks.
