In cryptography, a padding oracle attack works like this: you probe a system, and how it responds reveals something about your own input. You learn the game by playing it. Working on River has challenged my thinking about human-computer interaction in a way nothing else has, and that analogy kept nagging at me. Working with an AI agent in public surfaces something you don't get in a private window: you see how people think. The questions they ask, how they frame them, where they get stuck. River doesn't just flow through your work. It reflects it; and as an engineer learning from some of Shopify's best, that visibility is everything. It's how I've learned best & it's how I'm still learning. That's the ripple I didn't anticipate, all of us figuring out how to play. So... if you could ask an oracle anything, what would you actually ask? I'd ask if I'm onto something here, or losing it. Maybe both. (It's been a total honour to be a part of this effort, and we're just getting started 😝)

It has been a privilege and a blast to contribute to this effort! It's really the best to be able to see all the incredible things people are already doing with River, and make those things better

Very good questions imo experienced devs have a real advantage but only if they rapidly progress through their grief cycle and adapt, now and onwards. Categorically rejecting or ignoring the new layer would be a mistake.

This is three.js running on the Exosphere. 🤯 Rendering in realtime from a browser at 8K / 60fps. Here’s how Shopify just pulled it off 👇

This Jimmy Kimmel FCC threat thing is full anti-speech fascistic nonsense and is a huge breach of the republic. I do not talk like this lightly.

Today @Shopify is open sourcing the tool we use for optimizing glTF 3D models. 🔧 Tweak compression settings per texture ⚡ See changes immediately 🧰 Mesh compression options 🌐 Hosted online & free 👇 Check the thread for details

That means that it's possible to send byte sequences directly to the steering wheel in the format it expects. Logitech doesn't seem to publish this spec anywhere, but with Wireshark USBCap I was able to reverse engineer the exact bytes to send to the wheel to rumble.

This is a GIANT sleeper feature. Every Shopify storefront now exposes an MCP endpoint with tools to query merchant's catalog, look up store info, build a cart, and order status! Docs: shopify.dev/docs/apps/build/… — this instantly turns any MCP-capable agent into authoritative commerce agent.

It also works in VR 🤯 Grab a Quest or Apple Vision Pro and step into the immersive cockpit. Got to love WebXR and the amazing react-three/xr.

Here we go! 🌐 BFCM weekend has officially started in the first time zones, so let's go live. This is the best Live Globe experience yet. Beautiful. And what's even better than a bfcm globe? One in a room full with toys and tools to make it your own. We may have gotten a little bit carried away there... 😇

The biggest thing I took away from the whole try pear thing is I deleted cursor and installed continue.dev plugin in vscode and in my experience it's the best of the 3. Given this weekend's debacles, I'm limited my use of it to frontend dev, which it excels at.

It’s official: @Shopify is the first commerce integration partner on @Roblox. Soon, you’ll be able to shop physical products like clothing, accessories and collectables designed by your favourite creators and brands, all within Roblox, and it’s all powered by Shopify. This means that developers, creators, and brands who are on Shopify, can sell DIRECTLY within their Roblox games. More spaces to connect with fans means more opportunities to succeed as an entrepreneur, and that is what we are powering at @Shopify. See you soon on Roblox 🚀

Yesterday, @binarybits interviewed @linakhanFTC at @YCombinator. Sen Wiener later spoke at the same event. Today, @binarybits has written the best explainer yet about why Sen Wiener's SB1047 is problematic. A *must read* for anyone following SB1047: understandingai.org/p/a-cali…

this was our first time playing with shape keys inside GLTF and we learned a ton you can move geometry without rigs or transforms, which can be super powerful, but you only get two keyframes and verts move linearly between them you can see my path for the U doesn't curve around

The hero on the latest @Shopify Editions page was all built with React Three Fiber. Here’s how we did it 👇

A order on @SaltandSundry just tipped Shopify over the 1 trillion(!) in cumulative GMV. Monumental milestone for us. A beautiful small business run by Amanda McClemens in DC. Couldn't have been a better example of what makes Shopify special: shopsaltandsundry.com/pages/…

Can't believe I got this working 🤯 Live preview of a Blender scene with the Vision Pro.
