The Changelog: Software Development, Open Source

Today on the show I’m talking with Amelia Wattenberger — designer, data-viz veteran, ex-GitHub Next, and now designing Intent at Augment Code. What if the last 30% of any software project is about to become the hardest part you’ve ever done? That’s the argument Amelia is making today. We discuss the identity crisis developers are having as agents take over the keyboard, the epic redesign of developer tooling in this agent-first world, the arc from autocomplete to chat to CLI back to UI, why Intent treats a workspace as their core primitive not a chat thread, the tradeoffs between one-worktree-per-agent vs. one-worktree-per-task, and why she thinks prototyping just got easier but finishing got harder.

Astral is joining OpenAI, which says a lot about where the center of gravity is moving for developer tools, LiteLLM got hit by a nasty supply-chain attack, and OpenCode blew up as the latest serious open source swing at the coding-agent stack. We’ve also got Rust doing a very public reality check on its own pain points, WorkOS pushing AuthKit into CLI auth, Ryan Lizza using AI to build an open source TurboTax alternative, and a fresh httpx fork that turns open source maintenance drama into a real dependency story. If nothing else, this week was a good reminder that tools, trust, and control all move together.

This week’s been wild — Iran bombed AWS data centers to take down Claude, OpenAI dropped GPT-5.4 (and it’s seriously good for coding), and living brain cells are literally playing DOOM. We’ve also got a heartfelt take on what it feels like to be a 10x engineer in the age of AI, plus some cool new tools like Handy for speech-to-text and web haptics. Oh, and new MacBook Pros with M5 Pro and M5 Max are up for pre-order. Try not to impulse buy (or do).
