Unpopular opinion: “Confirm password” fields are bad. Forcing users to enter passwords twice adds friction and lowers conversion rates. Why optimize for a couple users who make a typo? Just let them reset their password. More friction for a few, less friction for most. 👌

We just released Tailwind CSS v4.1.6 and made some improvements to the upgrade tool. You should be able to run the upgrade tool on existing Tailwind CSS v4 projects, and keep them modern and up-to-date. `npx @tailwindcss/upgrade@latest` But what can it do?

Did you know not all magnesium is the same? - Glycinate: sleep + anxiety - Malate: energy + pain - Citrate: digestion - Threonate: brain + memory If you’re just guessing, you’re wasting money.

Funny how @expo feels like it's become React Native core rather than being just tools and libs Not sure who can still consider making a React Native app without using any of their stuff The new Expo UI lib could become the core UI components for React Native! 😬

Prompt tip to dramatically improve Claude 3.7 Sonnet Thinking's reliability in Cursor Composer: At the end of your prompt, append "Make sure you're properly doing function calls when looking for files and creating/editing files." Small change, but makes a big difference.

A ton of confusion amongst Tailwind users comes from not realizing that if you are using CSS modules, or <style> blocks in Vue/Svelte/Astro, your CSS pipeline separately for every single one of those blocks. 50 Vue components using <style> means Tailwind runs 50 separate times.
