Miriam Suzanne joins the podcast to unpack the surprisingly deep world of CSS value resolution, the browser program running beneath every website. She explains how cascade and inheritance work together, why CSS custom properties introduce invalid at computed value time errors, and how CSS functions and mixins change the game. Plus: is Sass actually dead, or does it still solve real problems that the browser can't touch?
Most developers reach for date-fns or Moment.js without realizing the browser already ships a powerful string formatting library called the JavaScript Intl API. Killian Valkhof, creator of Polypane, walks through how locale-aware date formatting, currency formatting, the Segmenter API, and the Collator API can replace heavy npm dependencies, with support for over 7,000 locales baked right into every evergreen browser since 2017.
The Amazon AI coding outage reignited a debate the industry can't ignore: is this an AI failure or a process failure, and does that distinction even matter anymore? Paige, Jack, Paul, and Noel dig into vibe coding culture, the engineer retention crisis, and the rise of harness engineering as a discipline in this month's panel. They also tackle autonomous agents running while you sleep, zero-touch engineering, what a senior engineer even means now, and whether open source can survive the agentic era.
![TanStack, TanStack Start, and what’s coming next with Tanner Linsley [Repeat]](https://media24.fireside.fm/file/fireside-images-2024/podcasts/images/3/3911462c-bca2-48c2-9103-610ba304c673/episodes/b/b162bb97-3ddc-44ed-8979-3a4582696737/cover_medium.jpg?v=1)
In this repeat episode, Jack Herrington sits down with Tanner Linsley to talk about the evolution of TanStack and where it’s headed next. They explore how early projects like React Query and React Table influenced the headless philosophy behind TanStack Router, why virtualized lists matter at scale, and what makes forms in React so challenging. Tanner breaks down TanStack Start and its client-first approach to SSR, routing, and data loading, and shares his perspective on React Server Components, modern authentication tradeoffs, and composable tooling. The episode wraps with a look at TanStack’s roadmap and what it takes to sustainably maintain open source at scale.
