The IOCCC Flight Simulator was the winning entry in the 1998 International Obfuscated C Code Contest. It is a flight simulator in under 2 kilobytes of code, complete with relatively accurate 6-degree-of-freedom dynamics, loadable wireframe scenery, and a small instrument panel.
About three years ago I wrote an article analyzing the memory usage of arrays in PHP 5. As part of the work on the upcoming PHP 7, large parts of the Zend Engine have been rewritten with a focus on smaller data structures requiring fewer allocations. In this article I will provide an overview of the new hashtable…
First, I want to make it clear that I’m not accusing the compositor of true evil, which I define roughly as deliberately causing suffering. There’s unfortunately too much of that in the world. I mean it in the more metaphorical sense that it causes serious problems and forces other parts of the system to be more…
I last wrote in December 2019 about my work on speeding up the Rust compiler. Time for another update.
Today, Microsoft and Facebook announced at Facebook’s developer conference, F8 2016, that we’re adding Universal Windows Platform (UWP) support to React Native. This is provided as an open source, community-supported framework. The new UWP support extends the reach of these native apps to a new market of 270 million…

Swift is heavily used in production for building cloud services at Apple, with incredible results. Last year, the Password Monitoring service was rewritten in Swift, handling multiple billions of requests per day from devices all over the world. In comparison with the previous Java service, the updated backend…
Understand how using UUIDs as primary keys can affect PostgreSQL performance, and how to tweak your index to avoid UUID performance pitfalls.
Emacs 29 introduces tree-sitter support, a powerful parsing library that enhances its understanding of source code. With this integration, Emacs gains features like precise syntax highlighting, accurate indentation and easier extensibility. Here's how you install and configure Emacs with tree-sitter support.
Over on GitHub, David Yu has an interesting performance benchmark for function calls of various Foreign Function Interfaces ( FFI ):
This blog site has been archived. Go to react.dev/blog to see the recent posts. A few days ago, we wrote a post about upcoming changes to our legacy lifecycle methods, including gradual migration strategies. In React 16.3.0, we are adding a few new lifecycle methods to assist with that migration. We are also…
Dodrio is a new virtual DOM library that is designed to leverage the strengths of both Wasm’s linear memory and Rust’s low-level control by making extensive use of fast bump ...
There has been much discussion of using the Rust language in the Linux kernel (for example, here , here , and here ), at the Kangrejos Rust for Linux Workshop ( here , here , and here ) and 2021 Linux Plumbers Conference had a number of sessions on this topic, as did Maintainers Summit . At least…

Correctness in the face of cancellations: a written version of my talk at RustConf 2025.
A new analysis from OpenAI reveals issues in SWE-Bench Pro, a popular coding benchmark, raising concerns about reliability and accuracy in evaluating AI models.
It's not about technology for its own sake. It's about being able to implement your ideas.
The command line tool I created Sloc Cloc and Code (scc) (which is now modified and maintained by many other excellent people) counts lines of code, comments and makes a complexity estimate for files …
Why developers rarely use state machines, seeing them as overkill until it's too late to switch, and what the state_machine gem did for CrowdHired.
It's a bit of a silly post, because syntax is the least interesting detail about the language, but, still, I can't stop thinking how Zig gets this detail just right for the class of curly-braced languages, and, well, now you'll have to think about that too.
At Superwall we’re building an SDK to help App Developers increase their revenue by showing the right offer to the right person at the right time. Follow me on twitter for little tips and articles like this one.
