Time to join in the fun

People rewrite in Rust or Go and claim that as the reason for huge performance gains, at face value that's cool but when looking at what actually makes stuff faster it's almost never the language. A small thread.

Such a well written article

Introducing shadcn/lint. An agent-first linter for Tailwind design systems.

You define what’s allowed. When an agent breaks a rule, the error explains what’s wrong and how to fix it using your components, variants and theme.

There’s a lot you can do with this. Let me show you ↓

【The CITIZEN】

昨日、The CITIZENの展示会へ。

新作を見るというより、
改めてラインナップをじっくり見てきました。
そして、改めて感動しました。

年差±1秒、±5秒という驚異的な精度。
土佐和紙など、日本の伝統を取り入れた文字盤。
軽く、強く、美しいスーパーチタニウム™。

そして何より、
はなく、
ケース素材、文字盤、仕上げ。
一本一本を見ていくと、
「ここまでやるのか」

と思わせる技術とこだわりが随所にあります。
さらに印象に残ったのが、
時計をつくることだけで終わらない姿勢。

自然環境の保護・回復に取り組む
「1% for the Planet」。
年間売上の1％を環境保護活動に取り組む団体へ寄付し、
気候、土地、水、野生生物など、
地球環境の未来にも目を向けていく。
いい時計をつくる。
そして、その時計が生まれる未来の環境にも責任を持つ。

派手に凄さを語るブランドではないかもしれません。

でも、じっくり見るほど伝わってくる。
シチズンというマニュファクチュールの技術力と、
日本の時計づくりの底力。

昨日ラインナップを見ながら、
何度もそう感じました。
The CITIZEN、
本当に素晴らしい時計です。

そして、
また新たな挑戦が始まるようです。
これは楽しみです。

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

By definition, a digital watch displays the time using numbers rather than hands and indices. The A. Lange & Söhne Zeitwerk Date takes that basic concept and transforms it into one of the most daring expressions of mechanical creativity in fine watchmaking.

Lange’s signature timedisplay on the left and the minute display on the right in opposing horizontal windows. Every 60 seconds the numerals jump instantaneously with all three discs snapping forward together at the top of each hour. A peripheral sapphire ring surrounds the central grey dial and indicates the date with a subtle red marker. Dedicated pushers allow the hour and date to be advanced directly without cycling through the minute display. The date still advances automatically as the hour passes midnight.

The 44.2mm case is crafted from 18-karat white gold. Inside is the manually wound Caliber L043.8, featuring two mainspring barrels for a 72-hour power reserve and a remontoire constant-force mechanism that maintains steady energy to the balance while powering the instantaneous time display. It is an extraordinary showcase of German engineering that completely redefines what a digital watch can be.

I created my ViteConf 2026 mission credential. Create yours! viteconf.org/tickets/t/Iw8Y…

Very nice project to compile all the information of the different variation of the same CJK glyphs. Regional differences in each character also shows the different countries took different approaches to standardization and simplification of each variant.

Much love to the Solid team and congrats on launching Solid 2!

Cursor has largely completed this migration from Solid to React. We also have since converted all our scss and Tailwind to @stylexjs, in both Cursor and in @bot. The new agents window is 99% React, with a few stragglers left that we have yet to migrate. The big motivation for this migration was for perf and maintainability reasons. We have seen that in practice, it is actually quite easy to create perf footguns for yourself in signal based approaches when reactivity causes a large amount of accidental fan out in large and complex apps.

It probably was a skill issue. But in the age of agents, choosing what pitfalls you're okay with is an important decision. I think it's fair to say that every UI framework has its pitfalls and that no perfect one exists yet. For us, React was the most known quantity, and we found that solving its problems is actually quite straightforward and boring: exactly what you want when you're trying to ship! Something interesting I also observed is the uncanny valley effect of non-React frameworks looking like React. I think it confuses agents, because in my experience, agents were quite bad at writing good Solid code. Everything ended up being accidentally tracked which caused so many perf problems.

React Compiler solves most of your perf problems with over-rendering. The remaining cases just take some manual memoization or refactoring/composition, which an agent can easily do.

The nice thing about useEffect is that it's like an unsafe {} block in Rust: it shows me at a glance where the problems are. @bot (which is 100% React) is built on Dune, our in-house, agent friendly React framework for desktop apps, which actually bans useEffect outright and only exposes it indirectly through framework-provided hooks. Highly recommend setting something like that up for yourself!

We're releasing MuScriptor, the best open model for multi-instrument transcription to date, created in collaboration with @MireloAI.
Give it a recording in any genre: pop, classical, metal, jazz, whatever, and it transcribes the individual instruments into MIDI. Link in 🧵

Huge milestone for our team today: TypeScript 7 is now generally available--a native port that runs 10x faster. @typescript devblogs.microsoft.com/typescript/ann…

Have you ever wondered how I make some of the illustrations for makingsoftware.com?

Well, I made a video walking through some of the tooling I've made. Hopefully its interesting.

Beige & Brown color scheme went so hard against the grain for like 2 decades, it is unmistakably and forever Noctua.

It's so insanely visible in any system, any YT video, any media photo—and now we instantly associate Beige & Brown fans with high quality. Remarkable brand strategy.

Noctua is a proof that you can brand yourself distinctly different from the sea of sameness and beat them all through excellence across the board.
