We can load it like a normal Lisp library. CL-USER> (asdf:load-system "coalton") CL-USER> (in-package #:coalton-user) COALTON-USER> This…

Python's Innards: Introduction (2010)
A friend once said to me: You know, to some people, C is just a bunch of macros that expand to assembly . It’s been years ago (smartasses: it was also before llvm , ok?), but the sentence stuck with me. Do Kernighan and Ritchie really look at a C program and see assembly code? Does Tim Berners-Lee surf the Web any…

Four Years of Jai (2024)
I’ve been programming for long enough to be righteously cantankerous about a lot of things. The list of languages, frameworks and libraries I’ve worked with professionally or on personal projects is too long to list – but it includes everything from C and assembly languages through C++, Pascal and Delphi, through Java…

A look at the J language: the fine line between genius and insanity (2012)
I’ve been looking for a decent TSDB for years now. Took a shot at writing one in Lush using HDF5 (as others have done), but the experiments I did raised more questions than I got answers. I&#…

Lisp, Smalltalk, and the power of symmetry (2014)
Like many hackers, my first real programming language love was Lisp. Paul Graham, who inspired my own explorations of the language, is a particular advocate and has written quite a bit about Lisp a…

Initialization in C++ is Seriously Bonkers
I was recently reminded of why I think it’s a bad idea to teach beginners C++. It’s a bad idea because it is an objective mess—albeit a beautiful, twisted, tragic, wondrous mess. Despite the current state of the community, this post is not a polemic against modern C++. This post is partly a follow-up on Simon Brand’s…

Own Constant Folder in C/C++
I was talking with someone today that really really wanted the sqrtps to be used in some code they were writing. And because of a quirk with clang (still there as of clang 18.1.0), if you happened to use -ffast-math clang would butcher the use of the intrinsic. So for the code: __m128 test(const __m128 vec) { return…

When zero cost abstractions aren't zero cost
Rust is built around the concept of “zero cost abstraction”. The idea is that you can write human-friendly high level code and the compiler will give you for free performance at least as good as any optimized low level code you could have written yourself. With zero cost abstraction, you no longer have to trade off…

A deep dive into Multicore OCaml garbage collector
I recently gave a talk on the internals of multicore OCaml GC at Jane Street offices in NYC. The slides from the talk are available online . But I felt that the slides alone aren’t particularly edifying. This post is basically the slides from the talk annotated with notes.

The Isolation Trap: Erlang
Erlang's mailbox design is more disciplined than Go's channels: only the owning process can read from a mailbox, and sends are asynchronous. Yet the four failure modes of shared mutable state still show up, just in different shapes.

JVM exceptions are weird: a decompiler perspective
Some time ago, I played around with decompiling Java class files in a more efficient manner than traditional solutions like Vineflower allow. Eventually, I wrote an article on my approach to decompiling control flow, which was a great performance boost for my prototype. At the time, I believed that this method can be…

Nuitka Progress in 2015 – Python Compiler
For quite a bit, there have been no status posts, not for lack of news, but a lot has happened indeed. I just seem to post a lot more to the mailing list than I do here. Especially about unfinished stuff, which is essentially for a project like Nuitka everything that’s going on.
