LSP を活用してセマンティックなコード検索・編集能力を提供する MCP サーバー Serena の導入・使用方法を紹介。Claude Code でのオンボーディングからリファクタリングまでの実践的な活用例を解説します。 Serena はセマンティックなコード検索・編集能力を追加するオープンソースのツールキットです。MCP（Model Context Protocol） サーバーとして動作しているため、Claude Code や Cursor, VS Code のように MCP に対応しているクライアントであれば利用できます。またエージェントフレームワークとして Agno を使用しているため、特定の LLM モデルに依存せずに動作します。 Serena は LSP（Language Server Protocol）を使用してセマンティックなコードを解析するのが特徴です。LSP はコードの構
All JavaScript and TypeScript Features of the last 3 years
TypeScript as envisioned by Stable DiffusionThis article goes through almost all of the changes of the last 3 years (and some from earlier) in JavaScript / ECMAScript and TypeScript . Not all of the following features will be relevant to you or even practical, but they should instead serve to show what’s possible and to deepen your understanding of these languages.

本文書ではブラウザを利用したテスト自動化ツールを利用した経験がない人、これから Playwright を使ってみたいという人を対象に Playwright の基本的な操作方法について説明を行っています。Vue と React のプロジェクトでの Playwright の利用方法についても後半に説明しています。 Playwrightとは Playwright は WEB アプリケーションのテストを自動化するオープンソースのテストツールです。Playwright ではユーザが実際にブラウザを利用して WEB アプリケーションの操作を行う代わりにプログラムを通してブウラザ(Chromium、Firefox、WebKit)を動かすことで WEB アプリケーションのテストを行います。ツールを利用しない場合は機能を追加/更新する度に開発者がブラウザでページを開き動作確認を行う必要があります。Playw
We've talked quite a bit about linting in the past two posts of this series, so I thought it's time to give eslint the proper limelight it deserves. Overall eslint is so flexible, that you can even swap out the parser for a completely different one. That's not a rare scenario either as with the rise of JSX and TypeScript that is frequently done. Enriched by a healthy ecosystem of plugins and prese

Large Text Compression Benchmark Matt Mahoney Last update: July 3, 2025. history This competition ranks lossless data compression programs by the compressed size (including the size of the decompression program) of the first 109 bytes of the XML text dump of the English version of Wikipedia on Mar. 3, 2006. About the test data. The goal of this benchmark is not to find the best overall compressi

New section for custom properties in Elements > Styles The Elements panel now supports the @property CSS at-rule. It lets you define CSS custom properties explicitly and register them in a stylesheet without running any JavaScript. To inspect your registered custom properties, in Elements > Styles, hover over the property name and see its descriptors in a tooltip. In the tooltip, click the link to
TL;DR: How can you determine whether a JavaScript native function was overridden? You can't — or at least not reliably. There are ways to get close to it, but you can't fully trust them. Native functions in JavaScript In JavaScript, a "native function" is a function whose source code has been compiled into native machine code. Native functions can be found in JavaScript's standard built-in objects

pow-captcha
💥PoW! Captcha A proof of work based captcha similar to mCaptcha. Compared to mainstream captchas like recaptcha, hcaptcha, friendlycaptcha, this one is better for a few reasons: It is lightweight & all dependencies are included; total front-end unminified gzipped file size is about 50KB. It is self-hosted. It does not spy on you or your users; you can tell because you run it on your own server, y

Casual Parsing in JavaScript August 16, 2021 Over the last year and a half I've gotten really into writing parsers and parser-adjacent things like interpreters, transpilers, etc. I've done most of these projects in JavaScript, and I've settled into a nice little pattern that I re-use across projects. I wanted to share it because I think it's neat, and it's brought me joy, and it could be an intere
Key Information In June 2022, the Sonar Research team discovered critical code vulnerabilities in multiple encrypted email solutions, including Proton Mail, Skiff, and Tutanota. These privacy-oriented webmail services provide end-to-end encryption, making communications safe in transit and at rest. Our findings affect their web clients, where the messages are decrypted, mobile clients were not aff
