I've been using Elm since about one year back now. At the start of 2021 I began working with a client that had an existing Elm frontend code base and an early stage backend built in Elixir and Phoenix. This post will be about my experiences running face first into Elm. I'll be vague on some details as I can't share…
This is a short response to the recently announced Go 2 generics draft proposals
Many Rust beginners with a background in systems programming tend to use bool (or even u8 – an 8-bit unsigned integer type) to represent “state”. For example, how about a bool to indicate whether a user is active or not? struct User { // ... …
Many people, including myself, have implemented garbage collection (GC)libraries for Rust. Manish Goregaokar wrote up a fantastic survey of thisspace a few y...
Ever wondered how Clojure's persistent vector actually works? This is part 1 of a blog series which aims to explain them.
Martin Uecker, 2025-08-10 I discuss the implementation of type and bounds safe generic containers in C. Previously, I discussed a span type , bounds checking using arrays . and a a vector type . This time, I will discuss maybe inspired by Haskell. This type can used to return a value that may not exist, e.g. because…
I’ve been thinking about garbage collection in Rust for a long time, ever since I started working on Servo’s JS layer. I’ve designed a GC library, …
The next HHVM release, 3.6, is on the horizon. We expect it to be released at the very end of February or in early March. It’s going to be a big release. Not...
I wrote my first line of Rust in June 2015, a month after Rust 1.0 landed. Coming from C, Python, and JavaScript, I never looked back. Two Rust-based startups and 500k lines of Rust later, here are some reflections on the milestone.
Imagine someone let you into an alien spaceship they landed in your backyard, sat you at the controls, and encouraged you to fly the ship...
For the first time, AdaCore’s GNAT Pro subscribers will be able to develop safety- and security-certifiable embedded applications using Rust while…
Macros are required to do some very helpful things in Rust, but this isn't an article about any of those things.
Sometimes we start things but decide midway through that we would prefer to rather not be doing them. That process is sometimes referred to as cancellation. Say we accidentally clicked "download" on a large file in the browser. We should have a way to tell the computer to stop downloading it.
Abstract Syntax errors are generally easy to fix for humans, but not for parsers in general nor LR parsers in particular. Traditional ‘panic mode’ error recovery, though easy to implement and applicable to any grammar, often leads to a cascading chain of errors that drown out the original. More advanced error recovery…
Introduction Link to heading I just got home from JuliaCon, the first conference dedicated entirely to Julia. It was a great pleasure to spend two full days listening to talks about a language that I started advocating for just a little more than two years ago. What follows is a very brief review of the talks that…
We are releasing the second patch release of the 1.2 series.
Overture to our small Lisp to x86-64 compiler
A new year is upon us. Before the world ends, let’s take a look back at what 2011 meant for everybody’s favorite programming language:
If you’ve ever needed to hit a breakpoint programmatically in C++, you’ve probably written something like this: 1 2 3 4 5 6 7 8 9 #if defined(_MSC_VER) __debugbreak(); #elif defined(__clang__) __builtin_debugtrap(); #elif defined(__GNUC__) && (defined(__i386__) || defined(__x86_64__)) __asm__ volatile("int3"); #else…
A brief overview of our study of abstract-syntax-tree and bytecode interpreters on top of RPython and the GraalVM metacompilation systems.

In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
We’ve learned the basics of Clojure’s syntax and evaluation model . Now we’ll take a tour of the basic nouns in the language.
