I did it. I qualified in my very first full Ironman, and now I have finished my first ever Ironman World Championship. What once felt like an impossible dream has finally come true.

A four-panel comic shows a worried man saying, 'We're cooked, AI will take over.' A robot responds, 'Generate an apple.' In the next panel, the robot presents a hamburger instead. In the final panel, the man smiles with relief, realizing AI won’t actually take over.

Look ma, my #WebAssembly course made it into the key repo (emnapi) that allows you to port existing Node-API native addons to WASM 🤯🤯🤯 Thank you so much for adding this to your repo @toyobayashi.bsky.social ❤️
Screenshot of the emnapi README that highlights a mention to Learn WebAssembly which is an online course to learn WebAssembly from the ground up.

🧠 Linear memory is WebAssembly's bridge between worlds — it's how Wasm modules share & manipulate data, following the same mental model C/C++/Rust developers know and love. Want to master these core concepts? Dive into my hands-on Wasm course at 👉 learn-wasm.dev #WebAssembly

What's cool is that along the way, you'll learn everything you'd need to implement such RPN (Reverse Polish Notation) calculator in plain Wasm (text format) by hand.

It absolutely is. But even if we do it's important to give credits where due 😊

Ever wondered how allocators work? Learn WebAssembly explains all of this in an interactive and fun way. Not only does it come with interactive components like these but also includes tools like a memory inspector to really understand how each instruction changes memory.

Learn WebAssembly isn't just a text-based online course. It's really practical and includes interactive components to understand concepts like a stack. It's a simple yet effective learning tool especially for those that learn better visually like myself.

T-7 days until my #WebAssembly course launches! 🚀 After 1.5 years of crafting this, I'm thrilled to share a truly hands-on WASM journey from the ground up. Every concept comes with carefully designed exercises because as Franklin said: "involve me and I learn"💡 Stay tuned!
