The internals and the latest trends of container runtimes (2023)
Last week I had an opportunity to give an online lecture about containers to students at Kyoto University. The slide deck can be found here (PDF): 1. Introduction to containersWhat are containers?Containers are a set of various lightweight methods to isolate filesystems, CPU resources, memory resources, system permissions, etc. Containers are similar to virtual machines in many senses, but they ar
Exploring the internals of Linux v0.01August 12, 2023 Linux kernel is often mentioned as a overwhelmingly large open source software. As of this writing, the latest version is v6.5-rc5, which consists of 36M lines of code. Needless to say, Linux is a fruit of hard work of many contributors over the decades. However, the first version of Linux, v0.01 was pretty small. It consisted of only 10,239 li
In this article, we’ll dive into the details of the way Paper functions as a TextView-based text editor for Apple platforms. The first article was just a warm-up — here is where we get to truly geek out! 🤓 Before we start, I’ll add that for the time being Paper is built on the older TextKit 1 framework, so the article is relative to TextKit 1. That said, all of the concepts, abstractions, and pri
Internals of async / await in JavaScript | Akash Hamirwasia
Internals of async / await in JavaScriptJuly 2, 2023 •11 min read If you have ever used JavaScript in the past, there is a high chance you have encountered the async / await syntax. async / await makes it easy to define asynchronous logic in a synchronous way that our brains can comprehend better. Some of you JavaScript veterans might know that async / await is merely a syntactic sugar over the ex
Regex engine internals as a library - Andrew Gallant's Blog
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata, which exposes much of the regex crate internals as their own APIs for others to use. To my knowledge, this is the first regex library to expose its interna
Deno is designed to streamline web and cloud development with built-in modern tools, direct access to web platform APIs, and the capability to import modules via npm. Web apps very often require some persistent application state. Setting up a database involves numerous configuration steps and the subsequent integration of an ORM or other systems. What if you could access such a database without an

github.com sqlc は何をやっているのか、問題に遭遇したときに調査するべき箇所はどこか？ というのを sqlc 1.20 時点の情報をもとに書いていきます。 背景 最近 sqlc に PR を送るようになり sqlc についての理解が深まってきたのでまとめておこうというのと理解を共有しておくことで PR を送る人が増えると良いなという思惑があります。 sqlc とは SQL Compiler の略でスキーマとクエリからパラメータと結果の型を推論するツールです。 その推論された型からコードを生成したり、lint のようなことが可能です。 コード生成が主な機能ですが v1.20 から sqlc vet が導入されています。 Linting queries — sqlc 1.21.0 documentation internals sqlc はスキーマとクエリからパラメータや結果の型
Scheduling Internals
A sneak peek to what's coming! I remember when I first learned that you can write a server handling millions of clients running on just a single thread, my mind was simply blown away 🤯 I used Node.js while knowing it is single threaded, I used async / await in Python, and I used threads, but never asked myself "How is any of this possible?". This post is written to spread the genius of concurrenc
async-task is one of the most complicated crates in the smol ecosystem. But, fundamentally, it’s just a future on the heap. I pride myself on smol packages being very easy to parse for anyone with a beginner’s level of experience in Rust. By that I mean, if you want to know how smol works, it should be very easy to pick up the source code, read through it, and understand how each individual part w
