One of my personal favorite features announced at WWDC will I suspect be a sleeper hit: container machines, allowing your Mac to run a lightweight, persistent Linux environment with your home directory and repos automatically mounted: https://t.co/dOBdfOOVxC
🧐 Flutter tips
How to easily highlight a single word within a string when all your app is translated many languages.
Just create a custom text wrapper.
Here's how I do this.
ps: this is a simplified version. I have way more options but this wasn't the goal of this tips.

Your Flutter widget tree is rebuilding 4x more than it should.
I profiled 3 production apps. Every one had the same problem.
6 mistakes silently killing your app's performance 🧵
remember when 512MB RAM was considered massive?
programmers wrote code like every byte mattered. optimized everything. squeezed performance from nothing.
suddenly nobody cared about efficiency anymore. just throw more RAM at it, problem solved.
now we have 32GB RAM and Slack uses 2GB just to show text messages. Electron apps eat memory like it's free candy.
we got better hardware and built worse software. abundance made us lazy.
Dart must easily be the most versatile computer language out there. 🎯
* Runs as a scripting language (like Python)
* Compiles to kernel code (like Java’s bytecode)
* Compiles to native code (like Swift)
* Compiles to JavaScript (like TypeScript)
* Compiles to WASM (unlike TypeScript)
* Has sound null safety (like Rust)
* Stateful hot reload (like no one else - Erlang maybe?)
* Runs on virtually any platform (like C/C++)
In addition:
* Has great developer tooling
* Interops easily with other languages
* Has an outstanding UI framework (Flutter)
* Nicely mixes with native UI components
* Is really easy to learn and work with
Today, I learned that the full compiler, analyzer, and tooling can even run on a web page. Mind blown. 🤯 What else did I miss?
We rewrote a React Native app in Flutter and the numbers went crazy. Better frame consistency, smoother UI. Flutter's Impeller engine is built different in 2026 fr 🔥
