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. 👌
Microsoft AI CEO, Mustafa Suleyman: By the end of 2025, models will move from one-shot answers to continuous planning With persistent memory and long-horizon planning, models will become deeply human-like no new algorithm, mostly compute and scale
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?

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.
