The code formatting and typography is frequent, controversial but probably unavoidable topic among programmers. This document contains some representative and possibly, relevant examples of the Lisp code.
Master them in 20 minutes. Use them every day.
Let me show you characteristics of APL that will influence your understanding of programming concepts and the way you use other languages.
One of the things people often complain about when doing Async Rust is cancellation. This has always been a bit confusing to me, because it seems to me that async cancellation should feel a lot like panics in practice, and people don’t complain about panics very often (though they do sometimes). This post is the start…
This post describes the implementation of pysmtgcc. See “GCC Translation Validation” for background information.
What's the deal with these two hooks?! Lots of devs find them confusing, for a whole host of reasons. In this tutorial, we'll dig deep and understand what they do, why they're useful, and how to get the most out of them.
A preview of `pavex`, an upcoming Rust web framework built around compile-dependency injection. An attempt to combine great development ergonomics with high runtime performance.
The top programs that have saved HN 100+ hours.
I love Ruby! I’ve used it every day for years and I’m not sick of it yet. It’s an easy language to love: it’s expressive, flexible and syntactically beautiful ; it has a unique combination of useful features like mixins , metaclasses and blocks ; it comes with a useful core library and comprehensive standard library …

Melrōse is both a language and a tool to create and listen to music interactively, The language uses musical primitives (note, sequence, chord) and many functions (map, group, transpose) that can be used to create more complex patterns, loops and tracks. Melrōse uses MIDI output to produce sound by any (hard or…
Explore the fundamentals of the DICOM file format! This quick introduction covers the basics of DICOM's structure, its essential uses, and tips for easily navigating its complex and abstract components.
I often work with clients who have large “data lakes” or big star schema style enterprise databases with fact and dimension tables as far as the eye can see. Invariably said clients end up with a substantial SQL codebase composed of hundreds of independent queries with lots of overlap between them. I want to be able…
When we see a world-class musician flawlessly play challenging music, it can be tempting to imagine that they were always able to do so. A moment’s thought makes it obvious that they must have had to spend huge amounts of time practising basic techniques in order to reach that level. What’s less obvious is that they…
When writing concurrent Rust you will encounter Arc and Mutex types sooner or later. And although Mutex might already sound familiar as it's a concept known in many languages, chances are you haven't heard about Arc before Rust. What's more, you can't fully understand these concepts without tying them to the ownership…
Everybody with an Emacs blogs raves about Emacs 29 these days. Things like Eglot, tree-sitter, SQL support and the like. Well, this is all nice – more than nice, brilliant! – but let’s not forget a few minor advances which are coming with Emacs 29. Let me mention a few things that I especially like.
"JVM Anatomy Quarks" is the on-going mini-post series, where every post is describing some elementary piece of knowledge about JVM. The name underlines the fact that the single post cannot be taken in isolation, and most pieces described here are going to readily interact with each other.
I have built up a pretty good workflow in the terminal. The main thing that I was missing until now was an easy way to drag and drop the files that I am looking at in a terminal to other apps.

A few years ago I've written in some detail about the Y combinator, including implementations in Clojure and Python.
Abstract TL/DR I present what I belive is a unique index for indexing and searching source code. It copies ideas from Bing bitfunnel implementation to create a very fast, memory efficient trigram …

This is a poorly structured list of common questions and answers about OCaml I had to ask myself or have been asked often.
How I've eased into a new language, Go, as a Senior Software Engineer, and some initial thoughts on the language.
Recently, a new set of sorting functions has landed in Go's golang.org/x/exp/slices package [1] . These functions leverage Go generics to provide a more ergonomic API for sorting (without requiring users to implement sort.Interface ), and also deliver a nice performance improvement, as the CL demonstrates.
Historically, large general-purpose libraries have formed the core of the Fortran scientific ecosystem (e.g., SLATEC , or the various PACKS ). Unfortunately, as I have mentioned here before, these libraries were written in FORTRAN 77 (or earlier) and remained unmodified for decades. The amazing algorithms continued…
