A “ quine ” (or “ selfrep ”) is a computer program which prints its own listing. This may sound either impossible, or trivial, or completely uninteresting, depending on your temper and your knowledge of computer science. Actually, it is possible, and there are some interesting ideas involved (in particular, writing a…
This technical deep-dive explains how V8 handles JavaScript properties behind the scenes.
In these videos, I talk about how VGA signals work and build a circuit that provides the correct timing of sync signals so that a monitor recognizes the signal and displays an image stored on an EEPROM.
Concurrent operations can be grouped relatively neatly into categories based on their cost
So the other day I both defined Tcl procedures all by myself and used them interactively, and I liked it, to the point where it felt like some kind of local optimum. This entry is an attempt to cope with the trauma of liking Tcl, by means of rationalizing it. I'll first tell the story of my fascinating adventures, and…
Named tensors for better deep learning code.
In Prague, the C++ committee took a series of polls on whether to break ABI, and decided not to. There was no applause. But I’m not sure we fully understood what we did and the consequences it could have.
Introduction: Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32
This PEP provides the motivation and rationale for PEP 634 (“Structural Pattern Matching: Specification”). First-time readers are encouraged to start with PEP 636, which provides a gentler introduction to the concepts, syntax and semantics of patterns.
This comes up regularly on Slashdot and I find it hilarious each time, but can never find it when I go looking for it. So, here it is:
In 2012, Apple added Gatekeeper to Mac OS X (now macOS). When you try to run Mac software downloaded from the internet, Gatekeeper checks whether the software was signed with a valid Developer ID certificate. If not, then Gatekeeper refuses to run the software. Over the years, Gatekeeper has become more strict…
A series of conversations between Kent Beck, David Heinemeier Hansson, and Martin Fowler. We discuss Test-Driven Development (TDD) and its impact upon software design.
``Frequently'' means thou shouldst draw thy daily guidance from it, rather than hoping thy code will achieve lint's blessing by a sudden act of repentance at the last minute. De-linting a program which has never been linted before is often a cleaning of the stables such as thou wouldst not wish on thy worst enemies…
February 9, 2021: Post updated with the current regional availability of container image support for AWS Lambda. With AWS Lambda, you upload your code and run it without thinking about servers. Many customers enjoy the way this works, but if you’ve invested in container tooling for your development workflows, it’s not…
New low-cost option for small businesses, Qt account requirement for installation and long-term support only for commercial licensees
My honeymoon with the Go language is extremely over. This article is going to have a different tone from what I’ve been posting the past year - it’s a proper rant. And I always feel bad writing tho...
After months of work, I am ecstatic to finally announce Bevy Engine! Bevy is a refreshingly simple data-driven game engine and app framework built in…
In this post, we explore cooperative multitasking and the async/await feature of Rust. We take a detailed look at how async/await works in Rust, inclu…
Welcome HN! Dark is a programming language, structured editor, and infrastructure—all in one—whose goal is to make it 100x easier to build backend services. Check out the website, our What is Dark post, and How Dark deploys in 50ms for more. Thanks for checking us out! Part of
In this course we explain how category theory—a branch of mathematics known for its ability to organize the key abstractions that structure much of the mathematical universe—has become useful for writing elegant and maintainable code. In particular, we'll use examples from the Haskell programming language to motivate…

This JavaScript demo application visualizes in detailed steps, how a text string is encoded into a QR Code barcode symbol. The content of this page essentially explains and justifies how my QR Code generator library works internally.
PHP 8.0 brings features like attributes, union types, and the JIT compiler. It has some important breaking changes, and improved performance.
Both QBE and LLVM are compiler backends using an SSA representation. This document will explain why LLVM does not make QBE a redundant project. Obviously, everything following is biased, because written by me.
My hobby : opening up McIlroy’s UNIX philosophy on one monitor while reading manpages on the other.
