What to Know Before Debating Type Systems (2008)
I was asked by someone to put this old piece of writing of mine somewhere more permanent, so here it is. A few comments off the top: This isn’t new. I wrote it years ago. Yes, I’m a b…

Clojure’s Approach to Identity and State (2008)
Many people come to Clojure from an imperative language and find themselves out of their element when faced with Clojure’s approach to doing things, while others are coming from a more functional background and assume that once they leave Clojure’s functional subset, they will be faced with the same story re: state as…

The Road to Valhalla
The goal of Project Valhalla is to bring more flexible flattened data types to JVM-based languages, to bring the programming model back in line with the performance characteristics of modern hardware. The core feature is inline classes (known previously as value types ), but such a fundamental perturbation of the JVM…

Building Fast Interpreters in Rust
In the previous post we described the Firewall Rules architecture and how the different components are integrated together. We created a configurable Rust library for writing and executing Wireshark®-like filters in different parts of our stack written in Go, Lua, C, C++ and JavaScript Workers.

Garbage Collection
We say Lox is a “high-level” language because it frees programmers from worrying about details irrelevant to the problem they’re solving. The user becomes an executive, giving the machine abstract goals and letting the lowly computer figure out how to get there.

Why the C++ standard ships every three years
WG21 has a strict schedule (see P1000) by which we ship the standard every three years. We don’t delay it. Around this time of each cycle, we regularly get questions about “but why so strict?”, esp…

Parallelism in Crystal
Crystal has made a huge step forward to have parallelism as a first class citizen. In short, you can set up the number of worker threads on runtime and each new fiber will be scheduled to run on one of them. Channel and select will work seamlessly. You are allowed to share memory between workers, but you will probably…

Overview of Rust error handling libraries
Rust's error handling is a pleasure to use thanks to the Result type . It ensures Rust's error handling is always correct , visible , and performant . And with the addition of the ? operator in Rust 1.13 , and the addition of return types from main in Rust 1.26 Rust's error handling has only kept improving.

Zig 0.5.0 Release Notes
Zig is a general-purpose programming language designed for robustness , optimality , and maintainability . Zig is aggressively pursuing its goal of overthrowing C as the de facto language for system programming. Zig intends to be so practical that people find themselves using it, because it "just works".

Typestates in Rust (2018)
A long time ago, the Rust language was a language with typestate. Officially, typestates were dropped long before Rust 1.0. In this entry, I’ll get you in on the worst kept secret of the Rust community: Rust still has typestates.

Swift UTF-8 String
Swift 5 switches the preferred encoding of strings from UTF-16 to UTF-8 while preserving efficient Objective-C-interoperability. Because the String type abstracts away these low-level concerns, no source-code changes from developers should be necessary*, but it’s worth highlighting some of the benefits this move gives…

Notes on a Smaller Rust
Many people who use Rust for a bit - especially those who like the language but do not fall in love with it - feel a sense that there must be a smaller, simpler variation on the same theme which would maybe be a little less powerful, but would also be much easier to use. I agree with them, but I think they are almost…

A final proposal for Rust await syntax
This is an announcement regarding the resolution of the syntax for the await operator in Rust. This is one of the last major unresolved questions blocking the stabilization of the async/await feature, a feature which will enable many more people to write non-blocking network services in Rust. This post contains…
