What's New in POSIX 2024
In the 1950s, computers did not really interoperate. ARPANET has not yet happened (that would become a thing in the 60s), and every operating system was typically tied to the hardware that was meant to run on. Most communication actually happened over telephone, and no company was more present in that space than the…

Fast Rust Builds
It's common knowledge that Rust code is slow to compile. But I have a strong gut feeling that most Rust code out there compiles much slower than it could.

Data-oriented design or why you might shoot yourself in the foot with OOP (2009)
Picture this: Toward the end of the development cycle, your game crawls, but you don’t see any obvious hotspots in the profiler. The culprit? Random memory access patterns and constant cache misses. In an attempt to improve performance, you try to parallelize parts of the code, but it takes heroic efforts, and, in the…

Towards Principled Reactive UI
Update 7 May 2022: A followup to this post containing significant conceptual advance is Xilem: an architecture for UI in Rust. I consider the Crochet experiment to be mostly negative, as there were a number of ergonomic and functional “paper cuts,” though several of the research goals were met, at least to some extent.

Syntax highlighters are wrong (2014)
Syntax highlighters make value judgments about code. Most highlighters judge that comments are cruft, and try to hide them. Most diff viewers judge that code deletions are bad.

js;dr = JavaScript required; Didn’t Read.
js;dr = JavaScript required; Didn’t Read. Pages that are empty without JS: dead to history (archive-org), unreliable for search results (despite any search engine claims of JS support, check it yourself), and thus ignorable. No need to waste time reading or responding. Also known as, if it’s not curlable, it’s not on…

Probabilistic Filters By Example
Probablistic filters are high-speed, space-efficient data structures that support set-membership tests with a one-sided error. These filters can claim that a given entry is definitely not represented in a set of entries, or might be represented in the set. That is, negative responses are conclusive, whereas positive…

JavaScript Needs Blocks
While reading Hacker News posts about JavaScript, I often come across the misconception that Ruby's blocks are essentially equivalent to JavaScript's "first class functions". Because the ability to pass functions around, especially when you can create them anonymously, is extremely powerful, the fact that both…

Brian Kernighan on the Typesetting of “The Go Programming Language” Book
A while ago, I bought the book “ The Go Programming Language ” written by Alan Donovan and Brian Kernighan. I have always been a fan of Brian Kernighan’s writings.

SIMD-friendly algorithms for substring searching (2016)
Popular programming languages provide methods or functions which locate a substring in a given string. In C it is the function strstr , the C++ class std::string has the method find , Python's string has methods pos and index , and so on, so forth. All these APIs were designed for one-shot searches . During past…

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.
