@jmwind Which makes pi’s use of a super simple prompt all the more amazing to me.

Spent time today reading through one of Anthropic’s massive Claude prompts after sniffing the network traffic. A 1,500 line prompt!
What surprised me wasn’t the personality tuning. It was the amount of embedded operational logic. Large parts were more akin to a programming language. API doc outlines, code samples, tool routing rules, formatting protocols, javascript snippets with dos/donts.
I used to think prompting is about wording, but these models are now invisible runtime systems behind a chat UI.

Dang man. Just let me finish my work. 😂 I was mid PR when my Shopify computer locked. Wouldn’t have had it any other way

I had neurosurgery 10 days ago and I’ve never been happier to have feeling in my hands back so that I can type at my full speed again. I’ll be out from work for another 6 weeks or so, but still building and playing at home!

I picked a great week to be offline and in the water with a group of Rubyists who are anti-drama.

The #RailsWorld talks are up in record time this year - 10 days! Quicker than some of you can recover from the jet lag. Enjoy!

People need to understand that the darkest forms of online radicalization don't lead to 'left' or 'right' orientations, but rather to an extreme, cynical, and purposely impenetrable disdain for society and existing power structures. Everything is irony; everything is a joke.

Super excited to see @floxdevelopment keep expanding where they’re taking Nix.
Flox@floxdevelopment
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.

@AmandaBPerino @bnferguson Congrats on another one in the bag. Amazing!

Just saw the last standing Rubyists off on a ferry to enjoy Amsterdam, and now it's home courtesy of the back of @bnferguson's bike. Life returns to normal. What a #RailsWorld. ♥️

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-fu…

Big day for @Cloudflare as we launch our newest compute primitive, Containers! A bit of history: In 2020, we acquired S2 Remote Browser tech and faced the challenge of migrating it from AWS to our edge. To run a Chromium-based browser securely, we split our team: half focused on the Remote Browser app, half built a robust, independent container platform to support it.
We knew some workloads needed to be close to users but didn’t fit our Workers isolate model. This platform became a game-changer, empowering dozens of internal teams to build features like Workers CI/CD, Browser Rendering, Key Transparency, Workers AI, and more.
But we kept asking: Is this the right primitive for our users? Workers remains the go-to for globally distributed, effortlessly scalable compute at a great price. Initially, many use cases we heard were for single-node webservers that didn’t need region earth. Then we got excited as users started asking for latency-sensitive, real-time applications and the ability to run agents close to the users they serve.
Cloudflare Containers are here to deliver for those high-performance, user-proximal workloads. Excited to see what you build with it!

This is pretty cool and a great addition to the CF platform.
Kristian Freeman@kristianfreeman
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.

@duncanthedev @SledgeDev @CactusRedsOgden @oliverhowells Yeah but I can’t make music.. so I pass the cool tag back to ya.

@SledgeDev @CactusRedsOgden @duncan @oliverhowells It’s okay he seems cooler, works at Shopify and has straight up @ Duncan which is way sicker than mine

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-agen…

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 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.
Jarred Sumner@jarredsumner
@RayFernando1337 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.
