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

Flutterアプリの定期リリースを支える自動化 - Fast DOCTOR Technologies TECH BLOG
本稿では、ファストドクターのモバイルアプリのリリースフローを整備した取り組みについてご紹介します。 モチベーション ファストドクターのモバイルアプリは、2022年夏にFlutterでのフルリプレースを実施し、それ以降は機能の開発が完了次第随時リリースをするという戦略を取っていました。 この戦略はシンプルであり、開発に関わっているステークホルダーが少ない状況下でうまく機能していました。しかし、組織の拡大に伴い以下のような問題が発生するようになりました。 複数機能の開発スケジュールの調整をしたり、バックエンドのリリース・QAとの整合性を取ったりという必要性が増し、調整コストが肥大化 リリースが不定期なため、いつPull Requestをマージすれば良いか分からずopenされたままのPull Requestが多数 この状況を改善するために、以下の要件を念頭に定期的なリリースとそれを支える仕組みを
2025: The year in LLMs

For previous years see Stuff we figured out about AI in 2023 and Things we learned about LLMs in 2024. It’s been a year filled with a lot of different trends.

written by Ruud van Asseldonk published 11 January 2023 For a data format, yaml is extremely complicated. It aims to be a human-friendly format, but in striving for that it introduces so much complexity, that I would argue it achieves the opposite result. Yaml is full of footguns and its friendliness is deceptive. In this post I want to demonstrate this through an example. This post is a rant, and

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,

Syntax Highlighting in Hand-Coded Websites The problem I have been trying to identify practical reasons why hand-coding websites with HTML and CSS is so hard (by hand-coding, I mean not relying on frameworks, generators or 3rd party scripts that modify the DOM). Let's say, I want to make a blog. What are the actual things that prevent me from making—and maintaining—it by hand? What would it take t
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
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. Starting with Node.js 24, support for MSVC has been removed, and ClangCL is now required to compile Node.js on Windows. The AsyncLocalStorage API
KDL is a small, pleasant document language with XML-like node semantics that looks like you're invoking a bunch of CLI commands! It's meant to be used both as a serialization format and a configuration language, much like JSON, YAML, or XML. It looks like this: package { name my-pkg version "1.2.3" dependencies { // Nodes can have standalone values as well as // key/value pairs. lodash "^3.2.1" op

JSer.info #584 - Deno 1.20がリリースされました。 Deno 1.20 Release Notes V8とRust間のOpコードの最適化をしてパフォーマンスの改善されています。 リクエストのAccept-Encodingヘッダを見て自動的にHTTP Response Bodyを圧縮するように変更されています。 また、deno benchコマンド、deno taskコマンド、deno.jsonがimportMapオプションをサポートしています。 Deno 1.19でDeno testでのリソースリークを検知する仕組みが実装されていましたが、パフォーマンスが悪化する場面がありました。 そのため、Deno 1.20では、deno testに--trace-opsフラグをつけた時のみデバッグ用の詳細な情報を表示するように変更されています。 破壊的な変更として、Workerと
今更ですが今年の2月に spaCy 3.0 が公開されました。 3.0 で導入された新機能の中で目玉と言えるのは、やはり Hugging Face Transformers (以下、単にTransformers) のサポートや PyTorch, Tensorflow との連携になるでしょう。今回はその辺りを実際に学習を動かしながら紹介したいと思います。 1. はじめに 今回は今年の2月に公開された spaCy 3.0 の話です。 spaCy は第4回でも紹介しましたが、研究者向けというよりは自然言語処理アプリ開発者向けのオープンソース自然言語処理ライブラリになります。日本語を含めた様々な言語の学習済みモデルが存在しており、 spaCy をインストールして、学習済みモデルをダウンロードするだけで、分かち書き、品詞や依存関係の推定、単語や文の類似度の判定など様々な機能を使用することができます。

はじめての自然言語処理 Hugging Face Transformers で T5 を使ってみる | オブジェクトの広場
前回が分量的にやたらと重かったので、今回はその反省(反動?)を踏まえて軽い感じでいってみます。第7回で紹介した T5 ですが Hugging Face の Transformers でもサポートされてますので、その使用方法をご紹介したいと思います。 1. はじめに 今回は久しぶりに T5 の話です。T5 に関しては第7回、第8回で一度紹介しているので、未読の方は記事に目を通してから戻ってきて頂けると、より理解がしやすいと思います。 さて、 T5 ですが Google のオリジナルコード(以下 “t5"と記述)1は敷居が高いと感じる方もいらっしゃるのではないでしょうか。 Estimator API ベースのコードや gin による設定など慣れていないと、とっつきにくいのではないかと思います。 そこで今回は Hugging Face の Transformers 2を使って T5 を動かす方法
PowerShell: the object-oriented shell you didn’t know you needed | Chris Warrick
PowerShell is an interactive shell and scripting language from Microsoft. It’s object-oriented — and that’s not just a buzzword, that’s a big difference to how the standard Unix shells work. And it is actually usable as an interactive shell. Getting Started PowerShell is so nice, Microsoft made it twice. Specifically, there concurrently exist two products named PowerShell: Windows PowerShell (5.1)

This article was discussed on Hacker News. This is a continuation of my last post on how to write a tree-sitter grammar in an afternoon. Building on the grammar we wrote, now we’re going to write a linter for Imp, and it’s even easier! The final result clocks in less than 60 SLOC and can be found here. Recall that tree-sitter is an incremental parser generator. That is, you give it a description o

Explicit Resource Management: Exploring JavaScript's and TypeScript's new feature | iliazeus
One of my favorite new features of JavaScript and TypeScript is explicit resource management. It brings new syntax, using foobar = ..., that enables RAII, reducing boilerplate when managing the lifecycle of various resources. In this article, I will explore this feature as implemented in TypeScript 5.2.0 with the disposablestack polyfill. I will mention both sync and async resources, DisposableSta

Introduction Some part of me has always been fascinated with coercing code to run in weird places. I scratch this itch a lot with my security research projects. These often lead me to writing shellcode to run in kernels or embedded hardware, sometimes with the only way being through an existing bug. For those not familiar, shellcode is honestly hard to describe. I don’t know if there’s a very form
Let’s Write a Tree-Sitter Major Mode Creating a standard programming major mode presents significant challenges, with the intricate tasks of establishing proper indentation and font highlighting being among the two hardest things to get right.

21st October 2024 I’m a huge fan of Claude’s Artifacts feature, which lets you prompt Claude to create an interactive Single Page App (using HTML, CSS and JavaScript) and then view the result directly in the Claude interface, iterating on it further with the bot and then, if you like, copying out the resulting code. I was digging around in my Claude activity export (I built a claude-to-sqlite tool
Python behind the scenes #11: how the Python import system works
If you ask me to name the most misunderstood aspect of Python, I will answer without a second thought: the Python import system. Just remember how many times you used relative imports and got something like ImportError: attempted relative import with no known parent package; or tried to figure out how to structure a project so that all the imports work correctly; or hacked sys.path when you couldn

Why DuckDB
There are many database management systems (DBMS) out there. But there is no one-size-fits-all database system. All take different trade-offs to better adjust to specific use cases. DuckDB is no different. Here, we try to explain what goals DuckDB has and why and how we try to achieve those goals through technical means. To start with, DuckDB is a relational (table-oriented) DBMS that supports the
Web scraping is the process of downloading data from a public website.
