I've sold out
I've sold out 2026-04-08 What a nice WebGL shader. Look at draining your battery. Table of contents So, this is awkward. I've joined Cristina, Jakob, Ramiz, Vegard, Armin, and Colin at Earendil. And I'm taking pi, the little coding agent that could, with me. Now, before you get out the pitchforks, hear me out. Why would you do that? Many reasons! Let me give you a "quick" history lesson. "It's lik
We deserve a better streams API for JavaScript
Handling data in streams is fundamental to how we build applications. To make streaming work everywhere, the WHATWG Streams Standard (informally known as "Web streams") was designed to establish a common API to work across browsers and servers. It shipped in browsers, was adopted by Cloudflare Workers, Node.js, Deno, and Bun, and became the foundation for APIs like fetch(). It's a significant unde
AI And The Ship of Theseus
Because code gets cheaper and cheaper to write, this includes re-implementations. I mentioned recently that I had an AI port one of my libraries to another language and it ended up choosing a different design for that implementation. In many ways, the functionality was the same, but the path it took to get there was different. The way that port worked was by going via the test suite. Something rel
The 1000 commits problem | Dave Kiss
Copy for agent Copied!@��� Claude Code’s latest release included 1,096 commits. And yesterday, one of those commits broke the entire CLI. Someone added a date to a changelog header—## 2.1.0 (2026-01-07)—and the version parser couldn’t handle the extra text. Every user who tried to run the CLI got an error. This is Anthropic we’re talking about, one of the most well-resourced AI labs on the planet,

【日本語訳全文】Kent Beck氏 基調講演：開発生産性測定のトレードオフ「グッドハートの法則」はもっと悲観的に捉えるべきだった・後編 - Findy Tech Blog
こんにちは。Findy Tech Blog編集長の高橋（@Taka_bow）です。 前編では、グッドハートの法則の本質と、指標に圧力をかけることで開発現場がいかに歪められるか、そして"もっと悲観的に捉えるべきだった"理由を見てきました。 後編では、Beck氏が提唱する「価値の道すじ」の概念と、AI時代における測定の問題、そしてリーダーが実践すべき具体的なアプローチについて解説します。 前編はこちら tech.findy.co.jp 講演動画 ※ 視聴には Findy Conference へのログイン、並びに視聴登録が必要です。ご登録頂ければ、他の講演アーカイブも視聴できます。 日本語訳全文（続き） ソフトウェアが価値を生み出す4つの段階 Kent Beck氏：ではどうやって抜け出すのか？プログラミングのジーニー（生成AIのこと）についてお話しします。 ソフトウェアの価値を生み出す方法は？
Verification-First Development
March 18, 2025 Verification-First Development Or: why test-first development is not the same as test-driven development A while back I argued on the Blue Site1 that "test-first development" (TFD) was different than "test-driven development" (TDD). The former is "write tests before you write code", the latter is a paradigm, culture, and collection of norms that's based on TFD. More broadly, TFD is
Web Components are not Framework Components — and That’s Okay • Lea Verou
Disclaimer: This post expresses my opinions, which do not necessarily reflect consensus by the whole Web Components community. A blog post by Ryan Carniato titled “Web Components Are Not the Future” has recently stirred a lot of controversy. A few other JS framework authors pitched in, expressing frustration and disillusionment around Web Components. Some Web Components folks wrote rebuttals, whil
It’s Time To Talk About “CSS5” — Smashing Magazine
Have you ever wondered what happened after CSS3? It’s common knowledge that we never saw CSS4 come after it, yet we have a plethora of new features that have no similar way of defining when they were introduced. The W3C CSS-Next community group is actively searching for better approaches for how we describe the evolution of CSS over time and identify feature sets as effectively as we did with CSS3
Why Patching Globals Is Harmful
Level up your testing skills by learning directly from me! Read more Honestly, I'd never thought I'd be writing about this, but the matter of patching globals turned out to be one of those topics that a lot of engineers seem to misunderstand. Most of us don't do monkey-patching, and even fewer stay around those implementations long enough to witness their impact. All the more reason to talk about
及川卓也「仮説はことごとく外れた」それでもブレずに開発できる理由は？【後編】 - エンジニアtype | 転職type
2024.04.08 働き方 及川卓也PdMプログラミングプロダクト 前編に続いて及川卓也さんにプログラミング初学者向けの学習サービス『Jasmine Tea』のこの1年を聞く。リリースからちょうど1年が経った『Jasmine Tea』だが「実は思っていたよりうまくいっていない」のだという。未知の挑戦に課題はつきものではある。及川さんらはどんな課題にぶつかり、それとどう向き合っているのだろうか。 事前に立てた仮説のことごとくが外れたこと、それでもブレずに開発を続けられている理由、少し脇道に逸れて、生成AI時代のエンジニアに必要なことも伺った。 Tably株式会社 代表取締役 Technology Enabler 及川 卓也さん（@takoratta） 早稲田大学理工学部卒業、日本DECを経てMicrosoftに転職。Windowsの開発に携わり、その後Googleではプロダクトマネジメント
YX problem | Structure and Interpretation of Computer Programmers
Software people are always all up in the XY problem: someone asks about how to do X when what they’re really trying to solve is Y. I find the YX problem much more frustrating: where software people decide that they want to answer question Y even though what someone asks is question X. I’ve seen a few different manifestations of this pattern: Respondent doesn’t know the answer to X, but does know t
GraphQL is for Backend Engineers - Apollo GraphQL Blog
Most articles explaining the benefits of GraphQL focus on advantages for the frontend: things like preventing overfetching, reducing round trips, and iterating faster. But GraphQL provides just as many advantages for backend developers, which is why I choose it by default for new APIs and why you should consider it, too. Improved communication The goal of building any API is to enable someone to u
What it was like working for GitLab
I joined GitLab in October 2015, and left in December 2021 after working there for a little more than six years. While I previously wrote about leaving GitLab to work on Inko, I never discussed what it was like working for GitLab between 2015 and 2021. There are two reasons for this: I was suffering from burnout, and didn't have the energy to revisit the last six years of my life (at that time)I w
The Performance Inequality Gap, 2024 - Infrequently Noted
The global device and network situation continues to evolve, and this series is an effort to provide an an up-to-date understanding for working web developers. So what's changed since last year? And how much HTML, CSS, and (particularly) JavaScript can a new project afford? The Budget, 2024 In a departure from previous years, two sets of baseline numbers are presented for first-load under five sec
