So cool that you’re talking about this publicly. I loved the sneak peak you gave me and ❤️ it so much. So proud of y’all!

Everyone's talking about AI-generated HTML.
But have you tried giving your sites a zero-config API for saving data, file storage, AI, websockets, etc?
We did this at Shopify. Runs on a single VM that costs $200/month, and it's changed the way we work.
We call it Quick 👇🧵

Driving Xcode 27 through the MCP connector from Claude and Codex is pretty great, especially when you use let the model drive the execution of your app through the desktop and iterate. 💥

One recommendation: The docs say to use `xcrun mcpbridge` but if you install the Xcode CLI tools separately, that can confuses things. I ended up going with `/Applications/Xcode-beta.app/Contents/Developer/usr/bin/mcpbridge` as the MCP command to use.

Super excited to see @floxdevelopment keep expanding where they’re taking Nix.
10 Sep 2025
We’re thrilled to share that Flox, the Nix Foundation, and @NVIDIA are teaming up to make it easier for teams working with NVIDIA’s CUDA GPU compute framework to build and ship CUDA-accelerated stacks.🎉
This partnership is about supporting developers with a more seamless experience and strengthening CUDA’s value across the wider ecosystem.
It’s a major step forward for anyone building AI, ML, HPC, and GPU-accelerated applications as teams can now build and deploy portable CUDA runtimes that just work, anytime and anywhere.
✅ The NVIDIA CUDA Toolkit will soon be available as a pre-built package in the Flox Catalog.
✅ This means CUDA-enabled PyTorch, Tensorflow, and OpenCV will also be available, along with… thousands of pre-built CUDA-accelerated packages!
✅ Users across the Nix and Flox ecosystems can create reproducible CUDA-accelerated environments for AI, ML, HPC, data science, and other use cases.

After leaving Shopify in June, I spent the summer with family and reflecting on the last decade and what I want out of the next. Along the way, I found unexpected inspiration in Linkin Park’s reformation story centering on creative collaboration. duncan.dev/post/summer-funem…

This is pretty cool and a great addition to the CF platform.

We're launching @Cloudflare Containers in public beta today. You can take a Docker container and deploy it to our network, with on-demand instancing and load balancing.

Almost four and a half years ago in early 2021, I went to work at Shopify. It was one of the best jobs I’ve had. But every tour of duty comes to a close. I’m going to take a few months this summer to really reflect on what I want to take forward with me. duncan.dev/post/free-agent-f…

Claude can create 50 API designs in minutes. ChatGPT can write endless variations. The new superpower isn’t generating work — it’s knowing what to reject.

I like this a lot.
New in Claude Code: Plan mode.
Review implementation plans before making changes. Perfect for complex changes where you want to nail the approach before diving in.

I picked up a new MacBook Pro on recent travels and the model I wanted at the Apple Store had a nano-texture screen. And oh boy, yah. Me like. It’s gooooood.

Trying to use bun in a ChatGPT Codex container? Here‘s the scoop. Hopefully a fix will land soon.
20 May 2025
We are working on a fix. I spent most of Saturday and Sunday on it, and @cirospaciari most of today. It’s a regression in our HTTP proxy client implementation impacting Envoy HTTP proxies introduced in bun v1.1.27 or so. We likely will have a fix tomorrow.

I’m totally stoked about this: zed.dev/agentic. Yes, Cursor and Windsurf and even using Copilot in VScode are good. But, I’ve got a soft spot for @zeddotdev and I’m so happy to see their new agent mode ship. Great agent in a super fast editor. 🎉

You know what I really dislike about GraphQL? All requests look the same in HTTP logs. I really miss not having that when I’m trying to figure out why something something that somebody is doing in their app is blowing up our SaaS provider.

I’m super stoked that we’re building on the partnership @Shopify has @withgraphite by investing in. I’m super bullish on Graphite and the team behind it.
18 Mar 2025
Today we announced @withgraphite's $52m Series B, led by @Accel with support from @MenloVentures & @AnthropicAI's Anthology fund, @a16z, @thegp, and our customers @shopify & @figma!
@Kyle_L_Wiggers from @TechCrunch covered the round!

Have a boarding pass to NY.
No boarding pass onward.
One airline says you’re good.
Trust us.
The other, we don’t know.
Board flight to NY.
Maybe this will straighten out.
Doubt it.
Convinced I’ll be buying a ticket for the next leg.
We’ll see.
How’s your day?

Reading Avery’s @tailscale.com post from earlier this month injected some optimism into my day. The c10k problem is now the c10000k problem. It’s a thought-provoking piece showing how we can do more than ever, with less than ever.
