On my way back to Rome from Montreal 🇨🇦🇮🇹 My experience at @rustconf was absolutely incredible! (Thanks @crtr0 and @CascadiaJS for this amazing hoodie. It’s super comfortable! See you hopefully in 2027!) I can’t wait to get home and start making videos again.

At @cascadiajs this year I gave a talk about #atproto and the Atmosphere: the open social ecosystem Bluesky and many other apps are built on, and what it means to actually own your data. I made a bunch of silly drawings for it, and I'm sharing them in this 🧵!

What are some smaller developer conferences that you absolutely love? Not the huge industry events, but more independent or community-run conferences with a really great vibe that people genuinely love attending 👀

"The best developer conferences are run by developers." In episode 4 of Building Forward, we're joined by @crtr0 to discuss building an event by devs, for devs. We even learned how humanity is at the center of the famous @CascadiaJS karaoke send-off 👇 🖤

Karaoke still runs on technology from the '80s. 🛼 What if we rebuilt it with Web Audio, AI, open-source models, and modern web APIs? Watch @monteslu give one of the most delightfully nerdy talks from CascadiaJS 2026. piped.video/wk2Fj2H5eoI

AI agents are getting real powers. Maybe it's time they stopped getting permanent credentials. @focusotter from @auth0 shows how human-in-the-loop authorization, scoped OAuth tokens, and short-lived permissions let agents act on your behalf, without giving away the keys to the kingdom. 🏰 piped.video/zRs08o4EP74

📦 What if bundling isn't the performance optimization it used to be? @moon_meister makes the case that HTTP/3 has changed the rules, and it's time to rethink decades of web performance advice around bundling, caching, and network requests. piped.video/F7J-yaGQqJI

What if you could leave a social platform without leaving your community? @brittanyellich explains how the AT Protocol lets you own your identity, your data, and your social graph, opening the door to a more open, portable, and developer-friendly web. 🌐 piped.video/_ZrChpf8FZ8

AI doesn't just hallucinate facts, it can hallucinate relationships. 🍄 Watch as @NyahMacklinDev shows us how knowledge graphs and context graphs help AI agents reason more accurately, explain their decisions, and become systems you can actually trust. piped.video/X_1EAwv_-Ow

AI can build your UI, but can it keep your brand consistent? 🎯 Watch as @kaelig explains how design tokens give AI agents a shared source of truth, helping teams build interfaces that stay consistent across apps, platforms, and themes. piped.video/CYy0PrnJISI

What happens when you fine-tune an AI on Beowulf, a 17th-century cookbook, and the history of Crisco? 📜 This talk from Molly Jean Bennet is a delightfully weird and thoughtful look at why making AI worse can actually make it more interesting. piped.video/tBE8hQjj3KM

If AI only learns from yesterday's ideas, who creates tomorrow's? @martypdx makes the case for building software that breaks new ground, and shares how to help AI work with innovation instead of reinforcing the status quo. piped.video/_pUpE2WM2zw

A live-coded morning rave is a pretty memorable way to start a conference talk. 🪩 Watch as @amhinson 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. piped.video/V_h_tMGgf6w

Will AI make programming languages irrelevant? 😲 Watch as @filipsodic argues the opposite: as AI writes more code, strong type systems become even more valuable. Learn why TypeScript isn't just surviving the AI era, it's becoming one of the best ways to capture intent, reduce bugs, and build better software. piped.video/WxhlRSfyxjY

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

"Just use Vercel." "Just use Supabase." "Just use Clerk." Cool. Now your auth, database, and deployment are owned by 3 different companies who can change pricing whenever they want. And the rest of your product is wrapping OpenAI. At some point you have to ask yourself: what do I actually own here?
