The Supabase and Google Maps edition of Multiplayer Geospatial Xmas Fun Special! Join a festive demo where we build a realtime Christmas treasure hunt using Supabase and Google Maps. Players join via QR, drop guesses on the map, and watch the heatmap light up as everyone races to find Santa’s lost present. We’ll peek behind the scenes at realtime channels, Edge Functions, geospatial queries, and a few helpful Google Maps features you can use in real apps.

A discussion what would happen if the AI Bubble bursts - Positive vibes through out...

What happens when you need to refactor 377 files in a SvelteKit codebase? Without AI, you retire. With Claude Code, you ship it in 11 hours.

This talk walks through real-world examples of using Claude Code for massive refactoring work that would be soul-crushing to do manually. I'll cover:

• How I approach large-scale refactors with Claude (377 files → 364 files → and counting)

• Building and activating Claude Code skills reliably (based on my viral post that's getting 4k+ views in 3 days)

• The workflow patterns that actually work vs the ones that waste your time

• Real examples from production codebases

This isn't about AI replacing developers - it's about using AI to handle the tedious parts so you can focus on the interesting problems.

React has changed a lot in the last year: React 19, 19.1 and now 19.2 brought a stable React Compiler, new hooks like useEffectEvent, the <Activity /> API, and better SSR primitives such as Partial Pre-rendering. And more

In this talk we’ll take a demo React app that’s full of effects, memoization and “old school” patterns, and modernize it step by step

In 2016, snapshot testing felt revolutionary. I promoted it everywhere. Then came the backlash: fragile tests, large snapshots, and mindless change approval. The community wasn't amazed. Yet in 2024, Node.js added native snapshot support. Why?

This talk traces snapshot testing's turbulent decade: from Facebook's game-changing release to general rejection, and examines what we got right, what we got wrong, and what place snapshots have today. Spoiler: the story isn't as simple as “snapshots bad”. Let's revisit with clearer eyes.
