Matthew hosts this week, joined by Kris and by Bailey Townsend, an AT Protocol community ambassador who builds tools for the atmosphere. AT Proto is the protocol underneath Bluesky, and this is a conversation about what it actually is beyond a social network. Matthew moved his own account onto a personal data server he runs himself, which is how Bailey first turned up in his replies asking whether he meant to delete his rotation keys. From there the pair expand on what a PDS is: your data, your identity, and your own way of doing authentication. Along the way there is Tangled, Leaflet, Hubble quietly mirroring 24 million repositories, and the reality that it's just a giant, web scale database. We've got supporter content, of course! This week that includes a report from AT Protocol Community Day at the Recurse Center, the difference between a Bluesky feed and a list, Matthew confessing he has never liked a single post, SDKs and notorious OAuth, and why warranty history should be on an open protocol.

Matthew takes the host chair this week with Kris as an unusually quiet producer. They're joined by Ron Efroni and James Bayer from Flox for a long conversation about Nix. Ron co-founded Flox and is also the president of the NixOS Foundation. James gives a live demo, going from flox search to flox activate with no commit SHA anywhere in sight, and Matthew finally gets an answer to a flake.lock code review problem: what exactly am I approving when the diff is one hash for another? Ron makes the cancel worthy claim that Nix is not hard, it just lacks opinionation by design, which turns out to be the entire reason Flox exists. Then the conversation turns to agents, why skills are software, and the company that uses Flox to turn back time on a model and replay the exact environment a bad answer came out of. We've got supporter content, of course! This week that includes Kelsey Hightower's hand in the containerize project, Ron on where the open source ends and the invoice begins, the customer who compared Flox to really good Wi-Fi, what actually keeps Ron up at night, Kris talking about the truly absurd amount of hardware humming away in his apartment, and a closing detour through AOL discs, Blockbuster late fees, and dedicated tape rewinders.

The proposal proposal gets the full Fallthrough treatment. Kris, Matthew, and Jamie dig into Austin's plan for taming the Go project's ever-growing proposal backlog. What starts as a recap becomes a referendum on how Go is governed, who gets heard, and what an open source community owes its members. Jamie brings a maintainer's reality check from Renovate's 1,700-item triage queue, Matthew wants to close the whole backlog and let people prove they care, and Kris argues the real product of a proposal system is discourse, not decisions. Along the way: whether Go is a democracy or a Google project, the joy economy that open source actually runs on, where "yes is forever" went when the UUID package shipped without consensus, and the gloves finally coming off over performative civility in Go's discussion spaces. We've got supporter content, of course! This week that includes Steve getting ratioed by Gen X on TikTok, T9 texting supremacy, why Go should never become a nation state, the IETF as proof that communities of joy do ship, and the biggest lie in open source.

Kris is back from GopherCon, Matt is back from the lawn, and Fallthrough is back with news: a brand new website and a whole new show, Continue: Go Proposals Edition, a weekly look at Go proposals. The topic for this week's Fallthrough? It's a listener-requested deep dive into what the two of them have actually been building with AI agents. In the regular edition, Kris runs a frontier-model pricing bake-off and comes away fascinated by how dirt cheap Luna is, Matt hands eight well-scoped Linear issues to overnight orbs and wakes up to three merged PRs, and the two land on a shared principle: even when the inference happens in a data center, the harness should run on hardware you own. It all wraps with Matt prototyping an integration by voice on a walk in the park. Expanded edition? We've got one of those! This week it includes Matt's deep dive on AMP betting everything on orbs, a breakdown of the proposal to change Go's proposal process, the one line that gives the whole document away, Kris's redesign built on gates, shepherds, and commitments, a hard conversation about civility and power in Go discourse, and the case for a decentralized Go.

We've got the classic trio of Kris, Matt, and Steve back to discuss Steve's impending cancellation for putting himself in the middle of some drama! Steve gives us a recount of the current saga between Zig, Rust, Bun, Fil-C, and his own programming language, Rue. The group discuss the problems with the drama, especially since it overshadows an amazing technical feat: a million lines of code ported to a new language in a week, then shipped to real customers, with a product that pulls in billions of dollars. Steve also made the mistake of complimenting Zig, which caused a 163 comment dog pile onto him. We've got supporter content, of course! This week that includes what it costs a community when the BDFL of a language says your code sucks, why the fear that LLMs can appear to think says more about us than about them, Steve on why you cannot ban a bunch of floats in a text file, Fil-C's promise of memory safe C and the trade-offs its author will not name, the pull request titled make Zig actually memory safe (unlike Rust), Odin not being notable enough, and Steve drops some exclusive new thoughts: agentic development is actually RTS macro versus micro.
