My favorite real-world performance test of multi-core performance is running the entire HEY test suite. It's native Ruby against Docker databases and around 30,000 assertions. It's insane how hard AMD x86 under Linux goes with these!

As I expected, browsers will either be replaced by AI Assistants (a la Jarvis) or become those AI Assistants.

My mind changed re: programming with AI as soon as I realized how much of the stuff I do when "programming" is just tedious grunt work. Programming with AI actually frees me up to do more programming, not less.

I've rewritten all the docs for Tempest's database component. Wow, it's pretty nice! I think I'm starting to like our ORM, actually 🤔

Building a fresh LinkedIn profile for Podscan is slow... and humbling :D But I know this needs to be done. SaaS sales without LinkedIn is self-sabotage.

A few days ago we hit a major milestone: Vite is now itself bundled by Rolldown! PR: github.com/vitejs/vite/pu… In addition: - Vue 3.6 will also be bundled with Rolldown. - Many libraries adopting tsdown (tsdown.dev), the successor to tsup, which is also powered by

We've been hacking on a "vanilla" version of Headless UI that uses custom elements and no framework. Just a <script> tag pointed at a CDN, and you can build custom dropdowns, dialogs, popovers, tabs, and more, without writing any JS at all ✨ Love letter to our Rails users ❤️

I just used Cursor to write a custom link verifier script for all of our markdown docs...in every TanStack repo. Then I told Cursor to use the output of that script to debug all of our broken links and update them using a probable list of solutions. I did this all in a few

Got this book when I met Sam Bhagwat (formerly cofounder of Gatsby, now of Mastra) It’s a short, sweet and practical intro into building AI agents. And it’s free to download as an ebook, I’ve learned (cont’d):

People ask me "why Tempest"? Of course I've had a vision for a while, but I now took the time to write it down: tempestphp.com/blog/tempests-…

I'm even more fond of Claude Code after this great convo with the creator and lead PM. Refreshingly practical and down-to-earth. No AGI nonsense. (I've used Claude Code more than other tools for coding. Especially to learn how the existing system works.) youtu.be/zDmW5hJPsvQ?si…

At first, prompting seemed to be a temporary workaround for getting the most out of large language models. But over time, it's become critical to the way we interact with AI. On the Lightcone Podcast, Garry, Harj, Diana, and Jared break down what they've learned from working with

This is exactly the way I've found the most success with AI-assisted programming. Think of it much more like "keyboards shortcuts on steroids" than as an actual thinking programmer conjuring up magic. You tell it exactly what to do, just in way fewer keystrokes.

"Vite is now distributed as ESM only" This is good. Everything should be this way.

Tanstack Router is fire 🔥 We've just migrated our core services from Next.js to Tanstack Router for 3 hrs and everything is just awesome. - Build performance: 4 min → 5 sec (Vite + no more Vercel dependency) - Type-safe path/query params - No SSR hydration errors

I've never enjoyed writing CSS, but two innovations solved that: 1. Tailwind. No more wasting time coming up with class names. No more worries about globals and brittle cascading styles. 2. LLMs. They're great at writing Tailwind, so I just tell the LLM what I want. Example:

The year is 2025. 18GB of RAM in a MacBook is not enough because you need to have a Chromium-based browser, Figma (a Chromium based browser), VSCode (a Chromium based browser), Docker (OSes running inside of an OS), and Slack (a Chromium based browser) all running at once.

Long video (1hr) but wanted to show a practical example of refactoring an existing codebase with AI. I did dependency upgrades, ran codemods, combined/deleted files, and more. I used Cursor Tab & Agent, as well as coding things by hand (gasp!)
