TabFS
Going through the files inside a tab's folder. For example, the url.txt, text.txt, and title.txt files tell me those live properties of this tab (Read more up-to-date documentation for all of TabFS's files here.) This gives you a ton of power, because now you can apply all the existing tools on your computer that already know how to deal with files -- terminal commands, scripting languages, point-

Microsoft Power Automate DesktopでRPAを実現してみる | 🌴 officeの杜 🥥
自分自身の個人的意見としては、エンドユーザコンピューティングは大いに結構だと思ってるけれど、一方で日本でジリジリと熱さが消えつつある国内の有象無象のRPAについては滅んだほうが良いとも思ってる。理由は後述するとして、本日良いニュースが発表されました。Power Automate Desktopについて追加費用無し無償で利用可能になるとのこと。これは既にあるMicrosoft365のEnterpriseプランなどに標準で利用できてるPower Automateのデスクトップ版のようで、Windows10に標準でついてくるようになるとのこと。 ということで、現時点のMicrosoft365で使えてるPower Automate Desktopを使ってみて、どんな感じなのか？またリリース後にその違いなどをここに記述していこうかなと思っています。また、Seleniumベースのウェブ自動化についても

I often feel like javascript code in general runs much slower than it could, simply because it’s not optimized properly. Here is a summary of common optimization techniques I’ve found useful. Note that the tradeoff for performance is often readability, so the question of when to go for performance versus readability is a question left to the reader. I’ll also note that talking about optimization n
Introduction In our previous exploration, we delved into the simplicity of HTTP/0.9, a protocol that served as the web’s initial foundation. However, as the internet evolved, so did its needs. Enter HTTP/1.0, a landmark version released in 1996 that laid the groundwork for the web we know today. HTTP/1.0 was a game-changer, introducing features that revolutionized web communication: Headers: Metad
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill.

JSONの小ネタと、JSONに対する拡張
JSONは最も普及したデータ形式の一つでしょう。JSONの仕様はECMA-404やRFC 8259として標準化されています。 ECMA-404 - Ecma International RFC 8259 - The JavaScript Object Notation (JSON) Data Interchange Format 細かいネタ 文字コード RFC 8259では、外部と交換するJSONテキストはUTF-8でエンコードされなければならないということになっています。BOMは禁止です。昔のRFCではUTF-16やUTF-32も許容されていました。 ただし、キーや文字列の中身としては単独のサロゲート（例："\uD800"）は禁止されていません。JSONのキーや文字列はUnicodeスカラー値の列とは限らないのです。 UTF-8を前提とする実装にとっては、単独のサロゲート（不正なUTF-

There are a lot of TypeScript fe
Today we’re excited to announce the release of TypeScript 5.6! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by adding syntax for types. Types describe the shapes we expect of our variables, parameters, and functions, and the TypeScript type-checker can help catch issues like typos, missing properties, and bad function calls before we even run our code.

Tao of Node - Design, Architecture & Best Practices48 minute read One of the main benefits of JavaScript is that it runs both in the browser and the server. As an engineer you need to master a single language and your skills will have a variety of applications.

In the early 90’s, being a frisian kid obsessed with computers there weren’t a ton of ways to get access to new software or learn more about computers. The two main ways were exchanging 3.5” diskettes with friends, or go to the library. One book I remember more than others was “Windows for Kinderen” (“Windows for Kids”) by Addo Stuur. I must have been around 10 years old and was obsessed by this b

Building data-centric apps with a reactive relational database
Building apps is too hard. Even skilled programmers who don’t specialize in app development struggle to build simple interactive tools. We think that a lot of what makes app development hard is managing state: reacting and propagating changes as the user takes actions. We’re exploring a new way to manage data in apps by storing all app state—including the state of the UI—in a single reactive datab
