Syntax - Tasty Web Development Treats

Scott, Wes, and CJ break down the latest Pi updates, including durable long-running agents, Codemode, and MCP support, then debate whether pull requests are dead in favor of issues. Plus Supabase picks up Turso, Screen Studio 4 drops, JavaScript Composites bring value-based equality, and a stack of new AI models from Google, OpenAI, Cloudflare, and more.

Scott and Wes answer listener questions about what replaced blogging, what to do while your AI agent works, and who should pay for token costs. They also cover keeping agents from going off the rails, getting your team excited about AI, and staying motivated when AI takes the fun out of coding.

Scott, Wes, and CJ ask whether Ruby on Rails is really dead (and whether Rust is just Rails you don't have to read), then dig into Meta's new Muse agent, which is free, comes with its own VM, and is already reading messages nobody asked it to. Plus: upm, a tiny TypeScript npm replacement, Opus 5.5 moonlighting as a motion designer, Tart VMs on Apple Silicon, and a foundry for gloriously bad web fonts.

Scott and Wes ditch Electron and Tauri for GPUI, the GPU accelerated Rust UI framework from the Zed team. They get into its React-like API, styling that feels a lot like Tailwind, GPUI Kit components, the community fork drama, and the tiny desktop apps Scott has built with it.
