I built an app to simulate the 2026 NCAA tournament! It uses historical data, KenPom rankings, game locations, and more to determine the win probability. ...but then has an AI model review the results and prompt for the reality of March Madness, unpredictable!

My latest experiment… Built a game with Cursor! It’s written in Verilog, which compiles to a bitstream that programs the FPGA 🤯 Has been fun to learn more about hardware and game dev.

Cursor tip: if you're doing web dev, there's an integrated browser! The agent can read console logs, network requests, and even control the browser to do automated testing for you. You don't have to install any third-party MCP servers, just works 😄

I built a clone of the Yeezy store with Next.js. This was a fun challenge — the site has some smooth animations and feels very fast. But it was bothering me that I couldn't use the browser back button. Can we do better? So I rebuilt the site with v0 and Motion. Here's how it works: 1. When you click on a product, Motion is able to animate the original position of the product in the grid, to the zoomed in product detail page. 2. During this transition, we also shallow update the URL with the `/p/slug` route for the page. 3. If you press the back button in the navbar, or use the browser back button, or press escape — all options will take you back to the main product listing page. 4. If you reload the page while looking at a product, or someone sends you a link to a specific product, it still works! This is the best parts of a SPA and MPA mixed together. In the future, I can make this even better with View Transitions (I wasn't able to get the product animation just right, but if you can I'd love to see it!). I also took some creative liberties from the original design. The whole 1/2/3 size thing, where you needed to click the "?" to see SM/MD/LG was strange, so I just went directly to those sizes. Similarly, I prefered the more traditional style sheet/modal with the background color change, versus the full screen takeover. If you wanted to actually hook this up to Shopify now, you can swap the cart implementation with Next.js Commerce, which has all the APIs you need + optimistic writes 🔥 Should I make a video walking through the code?

It's pretty neat to easily control a Linux computer in the cloud. For this one, I added an AI sidebar which can control and navigate pages.

My friend is a 10x software engineer. He is insanely gifted. We were looking at the Yamauchi No.10 Family Office website together years ago and I asked him what it would cost to build it today. I will never forget his answer… "We can’t, we don’t know how to do it."

How are coding agents changing software engineering? Yapped for 15 minutes about new Cursor data we published, including: 1. Why lines of code is an imperfect measure of AI progress 2. Balancing intelligence/cost/speed for models 3. Code reviews with "Mega PRs" (1000+ lines)

Cursor just got a major upgrade! Agents can onboard to your codebase, use a cloud computer to make changes, and send you a video demo of their finished work. The latency of using the remote desktop is smooooth.

I built a Rust-based image compressor, WASM binary, and SvelteKit app! I wanted to see how far I could go using only coding agents. I did not write any code by hand. After 520 agents, 350M tokens, and $287 I can now say… extremely far.

Rules, commands, MCP servers, subagents, modes, hooks, skills... There's a lot of stuff! And tbh it's a little confusing. Here's what you need to know (and how we got here).

John moved away from Next.js – what went wrong? They felt the navigation was slow and ultimately ended up migrating away. Made a quick video to explain the different data fetching patterns building dashboard apps and how John can get snappy navigations without loading spinners.

Cursor now has a built-in web browser. You can say "start my app" and it will run the dev server in a terminal and then navigate the browser to localhost:3000. It can take screenshots of the page for iterating on design, and you can send DOM elements to the agent with prompts!

Cursor now natively supports git worktrees. You can run multiple agents in parallel, each with their own isolated copy of the codebase. This is great for comparing models or running the same model multiple times and picking the best result.

I noticed ⌘+F to search wasn't working on collapsed accordions. Told Cursor to fix it, went and made some breakfast, and then came back to this nice demo video. So many design details: wallpapers, chapter markers, showing keyboard input, pans/zooms, speeding up slow parts.

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!)
