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
How to review code effectively: A GitHub staff engineer’s philosophy
As a staff engineer at GitHub, code review is one of my main focus areas in my day to day work. Over the past eight years, I’ve reviewed more than 7,000 pull requests. Why so many? Because code review is crucial to building good software and another set of eyes can often spot issues you would have otherwise missed. I see code review as one of the most important aspects of my job. In fact, whenever
JavaScript is undoubtedly the most used programming language in the world and is hugely influential on one of the largest technologies we have all come to rely on – the internet. With this power comes great responsibility, and the JavaScript ecosystem has been rapidly evolving, making it incredibly hard to keep up with the latest JavaScript best practices. In this blog post, we will cover several

1行あたりの文字の表示数を多くすると文章が速く読めるようです。 レディング大学のポール・コラーズ氏（Paul Kolers）らの研究チームは、一行当たりの文字数と読む速さの関係性を検討しています。 結果、一文当たりの文字数が多いほど、読み終えるまでにかかる時間が短くなる現象が確認されました。 スマホやkindleで文章を読むときに縦ではなく横向きにし、一行当たりの文字数を多くすることで読み終わる時間を短くすることができるかもしれません。 また表示の文字の大きさを小さくし、一文当たりの文字数を多くすることでも早く読めるようになります。 この一行当たりの文字数を多くすることで読むスピードが速くなる現象は、日本語の文章を対象にした研究でも確認されています。 この研究の初期の報告は、学術誌「Human Factors: The Journal of the Human Factors and Er
I've hired a lot of developers over the years. More than a few of them have come in with a strong belief that our code needed heavy refactoring. But here's the thing: in almost every case, their newly refactored code was found by the other developers to be harder to understand and maintain. It also was generally slower and buggier too. Now, don't get me wrong. Refactoring isn't inherently bad. It'

Write OpenAPI with TypeSpec
I've spent the last few years at Microsoft working on an API definition language called TypeSpec. It's essentially a super flexible protocol-agnostic DSL for describing API shapes. You can try it in your browser at the TypeSpec playground. Many things about it are exciting, but I want to talk about one thing in particular: why TypeSpec is the best way to write OpenAPI. OpenAPI: the good and the no

Model Spec (2024/05/08)
May 08, 2024 Overview This is the first draft of the Model Spec, a document that specifies desired behavior for our models in the OpenAI API and ChatGPT. It includes a set of core objectives, as well as guidance on how to deal with conflicting objectives or instructions. Our intention is to use the Model Spec as guidelines for researchers and data labelers to create data as part of a technique cal
Recently I landed experimental support for require()-ing synchronous ES modules in Node.js, a feature that has been long overdue. In the pull request, I commented with my understanding about why it did not happen sooner before this pull request in 2024. This post expands on that comment a bit more. The opinions in this post are my own and reflect my perception of the ESM development in Node.js as
I previously wrote a quick intro to the endless method in Ruby and now I will try to use it to name transaction blocks in Rails. This is a technique Kasper Timm Hansen shared in a reply to my previous post. I will try to refactor some examples from two open-source Rails repositories just to explore how the code looks. This open-ended exercise is a playground for experimenting with the code shape a
When a single-page application needs to fetch data from a remote source, it needs to do so while remaining responsive and providing feedback to the user during an often slow query. Five patterns help with this. Asynchronous State Handler wraps these queries with meta-queries for the state of the query. Parallel Data Fetching minimizes wait time.

オーバーレイ ファクトシート
Webアクセシビリティ オーバーレイとは何ですか？オーバーレイは、Webサイトのアクセシビリティを向上させることを目的とした技術の総称です。サードパーティのソースコード（多くはJavaScript）を読み込み、フロントエンドコードを改善します。 アクセシビリティの向上を謳うWebサイトのアドオン製品は、1990年代後半に登場したReadspeakerやBrowsealoudに遡ります。これらは、インストールされたWebサイトにテキストの読み上げ機能を追加するものでした。 その後、そのようなソフトウェアに機能を追加した類似製品が、市場に出回るようになりました。それらは、読みやすさを向上させるために、ユーザーのニーズに基づき文字サイズや色などをコントロールするものです。 最近のオーバーレイ製品のなかには、支援技術からのアクセスのしやすさを妨げる問題を修正することを目的としているものがあります。

The good news I want to share is: not only will Ruby and Rails survive this AI revolution, Rubyists will pioneer
PowerShell: the object-oriented shell you didn’t know you needed
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)
Swift is well-suited for creating user interfaces thanks to the clean syntax, static typing, and special features making code easier to write.
