A live-coded morning rave is a memorable way to start a conference talk. 🪩 Watch as Alex Hinson shows how to build fast, private, task-specific AI tools with small local models, and why the right architecture matters more than simply calling the biggest LLM you can find. youtu.be/V_h_tMGgf6w

Will AI make programming languages irrelevant? 😲 Watch as Filip Sodić argues the opposite: as AI writes more code, strong type systems become even more valuable. youtu.be/WxhlRSfyxjY

Everyone wants to build AI tools. The hard part is proving they actually help. Watch as Jeff Otaño shares how OneBrief stopped chasing flashy demos, started measuring real outcomes, and used feedback loops to improve AI agents that fix production bugs. 🪲 youtu.be/LCKraOtFV-Q

AI may be changing software development, but it isn't replacing the need for junior developers. 🧑‍💻 Listen to Dylan Goings and learn why mentorship, diversity, and long-term knowledge transfer are more valuable than ever. youtu.be/S5XLYOsJ1u8

🧩 Design systems can't solve every UI problem. Watch as @jonathankeslin.com shares practical lessons for building shared components that scale across teams, with layered extensibility, sensible defaults, and escape hatches that keep both devs and products moving forward. youtu.be/haOndDHMGJQ

What happens when your "simple" API grows into an unmaintainable mess? 😅 This talk by @darius.cool explores the tradeoffs between configuration and composition, and why the right abstractions matter more than ever in the age of AI. youtu.be/dExasNlhVKM

What if AI agents use specs, not just prompts, to build software? Watch @ide.bsky.social, co-founder of @expo.dev, explain linked literate programming, a simple approach that keeps code, specifications, and intent in sync so AI can build more accurate, maintainable software. youtu.be/a8xYFd1ZLNQ

The best use of AI isn't writing code, it's helping you learn. 💡 Watch @daniel-mendoza.bsky.social's practical guide to mastering new frameworks by turning your AI assistant into a tutor instead of a code generator. youtu.be/foOOku3P9uQ

Ever click a button and wonder why your app freezes? 🤔 @cyatteau.bsky.social shows how web workers keep JavaScript apps responsive by moving CPU-intensive work off the main thread, with practical patterns for progress updates, cancellation, and debouncing. 📺️ Watch here! youtu.be/rh4RzLLPSis

CSS colors got a lot more powerful while most of us weren't looking. 🎨 In this talk @jdsteinbach.com demonstrates how features like light-dark(), relative colors, and contrast-color() can simplify theming, reduce design tokens, and make accessibility easier using browser capabilities.

What if the future of software development isn't one AI agent, but hundreds? 🤖 In this talk @joelhooks.com explores agent swarms, harness engineering, AI-powered workflows, and why the real challenge isn't building smarter agents, it's designing systems that make the best use of human attention.

AI coding agents are a lot like eager interns: they'll build exactly what you ask for... even when it's not what you meant 😅 In his CascadiaJS 2026 keynote, @erikch.bsky.social of AWS explains how spec-driven development helps teams get better results from AI coding tools. youtu.be/CGCLMky4OO8

JavaScript won the web. But more and more, when you peel back the covers, you see Rust 🦀 @francescociulla.bsky.social opened Day Two of CascadiaJS 2026 exploring why companies like Cloudflare and others are using Rust for performance-critical infrastructure, and where it fits alongside JavaScript.

This week I had the chance to attend #CascadiaJS. It was the first developer conference I’ve ever attended, and I’m still reflecting fondly on the experience. Thank you, @cascadiajs.com. Already looking forward to the next one. #CascadiaJS #SoftwareDevelopment

One of the best things that came out of @cascadiajs.com is this gif lmao @francescociulla.bsky.social

Posted some notes on @cascadiajs.com to my blog @graham.systems did I do this right? I installed and setup the @atmosphere.community plugin from @automattic.com. It doesn't look like a @standard.site card though, but maybe it's fine. www.tomresing.com/2026/06/04/f...

They don't make them like this anymore

I went to CascadiaJS half-expecting either AI hype or AI fatigue. I found neither, just a room full of working developers, quietly unsure, but building new things with a very familiar mindset. Some mu...
