James Fisher has a blog post on a case where GHC's runtime system imposed unpleasant latencies on their Haskell program: Low latency, large working set, and GHC's garbage collector: pick two of three The blog post proposes a very simple, synthetic benc...
CPS, or continuation-passing style, is an intermediate representation for programs, particularly functional programs. It’s used in compilers for languages such as SML and Scheme. Much of its utility comes from its support for tail calls and nonlocal control flow such as call/cc, but it can also be used as an…

How and why to use the Go race detector to improve your programs.
What’s new in Pydantic v2: 5-50x faster than Pydantic v1 and with substantial architecture improvements for enhanced safety & maintainability
Go 1.24 brings generic type aliases, map performance improvements, FIPS 140 compliance and more.
What ML-Flavoured Erlang is a statically typed language with basic parametric polymorphism (generics) for the Erlang VM that I’ve been hacking …
My colleague Loren Segal shared the blog post below. As you can see, he’s really excited about the new AWS SDK for Go! — Jeff; Today we are announcing the first Developer Preview Release of the AWS SDK for Go (v0.6.0). If you have not been following along with development, the AWS SDK for Go […]

λm.me - Compiling Lisp to JavaScript from scratch in 350 LOC
A toy (but working) compiler that turns Python syntax into x86-64 assembly using Python's built-in AST module.
Discover the new features in C# 9: top-level statements and target-typed new and conditional expressions. These features make C# less verbose and can be used in everyday programs.

CoffeeScript is an open source project that provides a new syntax for JavaScript. I have to say that I have a lot of respect for CoffeeScript and it got a lot of things right. The “golden rule” of CoffeeScript is “It’s just JavaScript” . That means there is a straightforward equivalent to every line of CoffeeScript…
Most J programs contain no loops equivalent to while and for in C. J does contain while. and for. constructs, but they carry a performance penalty and are a wise choice only when the body of the loop is a time-consuming operation. You are just going to have to learn to learn to code without loops.
It is my pleasure to announce a new open source project for the Swift server ecosystem, Swift Service Lifecycle. Service Lifecycle is a Swift package designed to help server applications, also known as services, manage their startup and shutdown sequences.
This post takes a short break from ASDL to expand on one of my Hacker News comments.
At a recent Clojure Berlin Meetup , Veit Heller gave an interesting talk on Macros in Clojure. The meetup was very enjoyable, and the talk...
Implementing a programming language is an experience no programmer should go without; the process fosters a deep understanding of computation, and it's fun!
The majority of performance improvements in modern processors are due to increased core count rather than increased instruction execution frequency. To maximise hardware utilization, applications need to use multiple processes and threads. Servers that process discrete requests are a good candidate for both…
A few years ago, on a whim, I wrote YAIOUOM. YAOIOUM was a static analyzer for Rust that checked that the code was using units of measures correctly, e.g. a distance in meters is not a distance in centimeters, dividing meters by seconds gave you a value in m / s (aka m * s^-1). YAIOUOM was an example of a refinement…
