AIバグ発見システム「Sashiko」をJS/TS用にカスタマイズして使ってみる - プププなテクブ
ソフトウェア開発におけるコードレビューは品質保証の要です。しかし、レビューの質はレビュアーの専門知識と集中力に大きく依存し、人間のレビューでは見落としが避けられません。 この課題に対して、Linuxカーネル開発コミュニティから生まれたのがSashikoです。 sashiko.dev 本記事では、Sashikoの仕組みを詳しく解説し、それをJavaScript/TypeScriptライブラリのレビュー向けにカスタマイズしたSashiko JSについて紹介します。 Sashikoとは何か？ Sashiko（刺し子）は、Google社員のRoman Gushchin氏が開発したAIを用いたバグ発見システムです。特にLinuxカーネルのパッチをAIで自動レビューします。名前の由来は日本の伝統的な補修刺繍技法で、「布の弱い部分を補強する」という意味が、コードの脆弱な部分を見つけ出すという使命に重ねら
Rust Is Eating JavaScript 2021 (updated 2026) – Lee Robinson Rust is a fast, reliable, and memory-efficient programming language. It’s been voted the most admired programming language for a decade1. Created by Mozilla, it’s now used at Meta, Apple, Amazon, Microsoft, and Google for systems infrastructure, encryption, virtualization, and more low-level programming. Why is Rust now being used to rep
REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with

How modern browsers work
Note: For those eager to dive deep into how browsers work, an excellent resource is Browser Engineering by Pavel Panchekha and Chris Harrelson (available at browser.engineering). Please do check it out. This article is an overview of how browsers work. Web developers often treat the browser as a black box that magically transforms HTML, CSS, and JavaScript into interactive web applications. In tru
One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m

Bun は WinterTC からの招待を無視し、標準から外れた拡張やまだプラットフォームで議論中の仕様を利便性のためだけに取り入れている。またエコシステムとして合意の取れていない実装をすることもある。 @jarredsumner: JS runtimes obsess about web standards but web standards orgs are incentivized to only care about browsers @lcasdev: @jarredsumner Just want to mention that we’ve invited you to WinterCG meetings for nearly 2 years now without any response from you - I think intentionally not partic
Today we’re excited to announce the release of TypeScript 5.1! If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript by adding constructs called types. These types can describe some details about our program, and can be checked by TypeScript before they’re compiled away in order to catch possible typos, logic bugs and more. TypeScript also uses these types to provid

Our strategy for making updates and maintaining stability while we migrate languages. In a previous blog post, we talked about why we are porting Turborepo, the high-performance build system for JavaScript and TypeScript, from Go to Rust. Now, let's talk about how. Today, our porting effort is in full swing, moving more and more code to Rust. But when we were starting out, we had to make sure that
Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

ts-blank-space
What is ts-blank-space? ts-blank-space is a fast type-stripping compiler that converts TypeScript to JavaScript. It supports a modern subset of TypeScript by erasing the types and replacing them with whitespace. That's it. It is not a type checker and does not perform any other code transformations. The underlying technique can improve build performance and simplify development. The implementation
Bringing Javascript to WebAssembly for Shopify Functions - Shopify
Bringing Javascript to WebAssembly for Shopify FunctionsWhile we’re working on getting our Shopify Functions infrastructure ready for the public beta, we thought we’d use this opportunity to shine some light on how we brought JavaScript to WebAssembly, how we made everything fit within our very tight Shopify Function constraints, and what our plans for the future look like.

At Stripe, our product docs are designed to feel like an application rather than a traditional user manual. For example, we incorporate a user's own API test key into code samples, making it possible to copy and paste code that seamlessly works with the user's own account. We have client-side interactivity, like checklists and collapsible sections. We tailor the content to the individual user, con
Vjeux » Birth of Prettier
React Conf is around the corner and it's been almost 10 years since Prettier was released. I figured it would be a good time to recount the journey from its early days to now. This is the story of how the "Space vs Tabs Holy War" ended, not through one side winning over the other but instead a technological invention making it the underlying source of tensions no longer being a thing. Back Story S
Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen. The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However
Flat config rollout plans - ESLint - Pluggable JavaScript Linter
Published 10 Oct, 2023 under API Changes Flat config rollout plans We have been working on the new configuration system for several years. Here's how we plan to roll it out. It may seem hard to believe, but the RFC for ESLint’s new configuration system, nicknamed flat config, was first written in 2019. It took until 2022 (v8.21.0) for us to release an experimental, opt-in version of flat config. S
2025-05-06, Version 24.0.0 (Current), @RafaelGSS and @juanarbol We’re excited to announce the release of Node.js 24! This release brings several significant updates, including the upgrade of the V8 JavaScript engine to version 13.6 and npm to version 11.

Notable Changes Permission Model Node.js now has an experimental feature called the Permission Model. It allows developers to restrict access to specific resources during program execution, such as file system operations, child process spawning, and worker thread creation. The API exists behind a flag --experimental-permission which when enabled will restrict access to all available permissions. B
My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise. I once tried that before with the Classic protocol (the one from 2009), but I quickly realized there wasn't really a way to properly parse binary data in bash. Take the following code sample: function a() { read -n 2 uwu echo
Introduction to Go 1.19 The latest Go release, version 1.19, arrives five months after Go 1.18. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

TLDR The relational model is great: A shared universal data model allows cooperation between programs written in many different languages, running on different machines and with different lifespans. Normalization allows updating data without worrying about forgetting to update derived data.

GitHub - endojs/Jessie: Tiny subset of JavaScript for ocap-safe universal mobile code
This document is an early draft. Comments appreciated! Thanks. Today, JavaScript is the pervasive representation for (somewhat) safe mobile code. For another representation to achieve universality quickly, it must be a subset of JavaScript, and so runs at least everywhere JavaScript runs. Whereas JSON is a simple universal representation for safe mobile data, Jessie is a simple universal represent
