Keep Your Enemies Closer

Steve is back! He joins Kris and Matt to discuss the drama around DHH's latest keynote at Rails World and Steve's latest views on AI. Interestingly, Steve believes that he'll sit in opposition to how Kris and Matt see the current situation. We start with Steve giving us the long backstory of Rails and DHH. The trio then dives into a conversation about purity tests, whether you can learn from people you dislike, and why making Linux a viable third option for desktop environments is important. From there they dive into whether the agents that carried out hacks were actually told to do that,…

Thinking, Fast and Cheap

Another week, another duo episode, but this time around it's Dylan who's joining Kris! He brings a fresh perspective to the AI conversation that Kris and Matt have been engaging in. The big question: is AI going to kill us all? Dylan thinks the odds are "astronomically small" and neither Kris nor him are going to lose sleep over the fear driven hype. The two are asking bigger questions: whether what language models are doing is thinking, why those who build these models in AI labs aren't actually the people who understand them the best, and whether TypeSafe AI's new Jev model is an LLM and…

Apocalypse Not Now

Kris and Matthew have some more spicy and it's about the latest AI news cycle: a greater than ten percent chance that AI wipes out humanity inside a decade. Neither of them are worried about it, what does is why everyone else is so worried about it. Kris brings his usual devil's advocate perspective: a 10% chance of extinction is also a 90% chance of non-extinction. He then widens the field of view to the more full argument, which is that AI is the easiest thing for everyone to point at. Matt takes a different direction and takes the argument at face value and walks it forward, ending with…

The Elements of Slop

Kris and Matthew have some feelings about AI they want to discuss. No, not about benchmarks or agents, but about the people using it to write things they should be plenty capable of writing themselves: the five paragraph LinkedIn post, the blog post, the tweet. Both Matt and Kris stumbled upon Pangram from the same source: Bryan Cantrill. The two go from there, discussing the ridiculousness of people writing short form posts fully with AI, to the purity tests that people insist on having, to the literacy crisis. This episode has a ton of spice, especially in the expanded edition. Speaking of…

A Record of One's Own

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,…

Be Kind, Rewind

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…

A Modest Proposal Proposal

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…

Backlog to the Future

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:…

Vibe and Prejudice

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…

Token Maxx: Fury Road

On this week, we've got Kris, Matt, and Dylan! Yes, Dylan is back to talk about GopherCon and his experience as a self declared late adopter of agentic coding. Dylan chairs GopherCon, speaks at it next week, and describes his own AI hockey stick as happening in about two months. Dylan walks through what is on the GopherCon program, then explains his coding agent tipping point: a dependency injection refactor he had written off that Claude finished in an afternoon. But he's not all in yet: he still won't let one robot review and approve another robot's code. From there the conversation turns…

I, Builder

Kris and Matt have a pretty big question they're trying to answer this week: in the age of AI, what does it actually mean to build something? We start (for real this time!) with the "SDKs are dead" discourse, and whether you still need one when you can just wrap the HTTP calls yourself. Kris then jumps the conversation to Beej's article on what it means to "make" or "build" a thing, he argues that we already lived through this during the analog-to-digital shift in music, photography, and video. Matt adds his own perspective from when he remodeled his kitchen. The duo doesn't stop with just…

Everything Agentic All at Once

Another week, another deep episode! Kris and Matthew are back and this one goes right off the rails in the best way. What was supposed to be a rundown of the new model landscape turns into a wide-ranging conversation about what AI coding agents actually mean for the people who write software. Matt brings a real dilemma: he had an LLM generate a working program and could not decide whether he still needed to read the code. That kicks off Kris's case for separating validation (did you build the right thing?) from verification (did you build the thing right?), an assertion that we already trust…

Landlord of the Rings

Kris and Matthew are back for a duo episode, and Kris has a hot take: ownership is terrible. What starts as a conversation about AI subscriptions versus API pricing turns into a wide-ranging discussion about what we actually gain by owning things, from Photoshop to your own compute to your house. Along the way, Kris and Matthew dig into why enterprises are drifting toward per-token pricing, why AMP's headless "own where it runs, rent the model" approach feels like the future, and why a number like "Meta spent 71 trillion tokens" tells you almost nothing about what got built. They also take…

Under Pressure

On this week's episode, Kris and Matthew have a topic: tension. Not the bad kind you learn to avoid, but the productive kind that, like a code smell, is worth stopping to examine. They discuss the challenges of APIs and stability, whether SDKs are actually necessary, and as always a little bit of life advice for our wonderful viewers/listeners. We've got supporter content, of course! This week that includes Kris's deep dive on why it's actually called soccer (and the perfect apple-versus-fruit comeback for every European), his love letter to Gerrit and patch-based review, Matthew on why the…

The Spy Who Banned Me

It's Fallthrough time! In this episode, Kris, Matthew, and Steve get into the time Steve pointed Anthropic's Fable at a side project he hadn't touched since January and watched it shepherd 95 pull requests in three days, the US government export banning Fable and its sibling Mythos, the insanity of Mythos popping a national security agency's boxes in a matter of hours, and why a software engineer that runs 24/7 for anyone with an account is exactly the kind of thing governments get nervous about. We've got supporter content, of course! This week that includes whether your AI agents should…

Of Fables and Mythos

Another week, another Fallthrough! In this episode, Kris and Matthew get into the US government slapping export controls on Anthropic's Mythos and Fable models, the marketing machine that made them sound world-ending, and how much of the AI hype actually holds up. We've got supporter content, of course! This week that includes whether your phone is already an extension of your mind and the "Clean Talk" cleaning influencers who will happily tell you to mix two chemicals that quietly kill you, the Egyptologist on a date who proves a person is smart but people are dumb, why we throw you in jail…

Shall We Play A Game?

Matt and Kris welcome Fernando Duran, the creator of SAD Servers, the site that drops you onto a broken Linux box over SSH with a timer running and dares you to fix it. They go through what SAD Servers is, the spite-fueled interview story that started it all, how companies use it to hire, and the surprisingly lean infrastructure (plus the tiny Go "checker") that makes the whole thing work. We've got supporter content, of course! This week that includes why technical interviews are broken and the spite that turned one into a business, taking the number two spot on Hacker News without toppling…

Pull the (AI) Lever, Kronk!

Matt and Kris welcome back Bill Kennedy who's been working on Kronk, AI tooling in Go. They go through what Kronk (and it's dependent library Yzma) is, the power of running models locally, and how they see coding agents and LLMs shaping the future of the industry. We've got supporter content, of course! This week that includes the message-caching trick that turns seconds into thirty milliseconds, why hybrid models quietly wreck the KV cache, Bill's "thirty billion knobs" explainer for dense versus mixture-of-experts models, why demo day is destroying engineering teams, and the…

Dependencies All The Way Down

Another week, another Fallthrough! In this episode, Kris and Matthew discuss a personal realization about what AI actually unlocks, their workflow philosophies, local models, a recent hot take from Mitchell Hashimoto, and a thought experiment that would break the NPM ecosystem overnight. Like the previous episode (a pseudo part 1), this episode returns to one question: are you moving in a direction, or just moving fast? Kris argues AI has lifted his coding domain ceiling entirely, while Matthew brings some nuance to the "just submit to the LLM, you're an architect now" take. The duo then…

Terminal Velocity

Has AI eaten all of tech? Is 600 billion tokens too many use in a single month? On this week's episode Matt joins Kris to talk about some of the current news in the tech industry. From OpenClaw's maintainer burning through $1.3 million worth of tokens to why we need more epistemic markers, to the rather absurd $725 billion that big tech plans to spend on AI CapEx this year. And of course, there are layoffs coming as well. Support content? We've got a whole bunch of that! This week that includes a ZFS war story where a thousand-fold write amplification bug stalls every file write, the case…

He Who Controls the Source

This week we've got Kris and Jamie! They open with the Shai-Hulud worm chewing through the npm supply chain and close on the messy economics of who actually pays for open source labor. And there's plenty of great stuff in between: GitHub's everything-platform creep, the case for LLMs as a way out of dependency hell, and the forge alternatives finally maturing into real options. We've got supporter content, of course! This week that includes an expansion on Kris's "pull requests as original sin" theory, the everything-platform rant that compares GitHub to Meta Business Suite, a monologue on…

Forging Ahead

Steve is back to talk JJ (Jujutsu version control) and the related product, ChangeSet, that he works on at East River Source Control. Kris and Steve trace why the GitHub monoculture is finally cracking, what JJ does that Git can't, and Steve's hypothesis that AI agents are pushing companies toward monorepos. Then the pair discuss the Opus 4.7 regression debate, the shift from "always use the frontier model" to using LLMs as one tool among many, and a quick discussion of the Tim Cook to John Ternus handoff at Apple. We've got supporter content, of course! This week that includes Steve's…

Regression to the Mean

Kris and Ian dig into the slow collapse of GitHub, starting with Ghostty off the platform after years of reliability problems. From there they trace Gary Bernhardt's old observation that we took a decentralized source control system and immediately put it behind a single point of failure, then widen the lens into AI as the engine of enshittification. The episode lands on a more optimistic note: maybe AI is also the tool that lets individuals rebuild the apps they used to have to buy. We've got supporter content, of course! This week that includes Kris's "AI was trained on the median of human…

No Country for Old Maintainers

Jamie returns, co-hosting with Kris for quite an eventful episode. They start with the Vercel breach, the Axios attack, nvim-treesitter, and Gorilla Mux. Kris draws parallels between the current AI hype cycle to everything that came before: Photoshop was going to destroy photographers, DAWs were going to destroy musicians, and now Claude Code is going to destroy software engineers. Just like the last episode, this one is filled with supporter only content. It's actually an extra episode and a half! This includes a deep dive on OAuth scope design and why consent screens need the Let's Encrypt…

Supply Chain Reaction

After last week's "Another Spectre In The Shell" episode, we felt we needed a follow up! This week Kris is joined by returning co-host Jamie Tanna, with Ian arriving fashionably late. They pick apart the post-Mythos announcement hype cycle, cover counter-narratives from the security community, and examine why our supply chain is already so broken that more powerful LLM barely changes the threat model. The conversation builds toward Jamie's unpop: "a little copying is better than a little dependency" is wrong, we should have more dependencies and then into practical supply chain defense. The…

Another Spectre In The Shell

It's Kris, Matt, and Steve this week. It's also Matt's last episode before becoming a father. The conversation opens with Claude Mythos, Anthropic's unreleased model that found 147 zero-days in Firefox's JavaScript engine and a 27-year-old bug in OpenBSD. Steve, who's lived through before, puts it in context. The panel also discusses cooldown periods for package upgrades, the implications of nation-state hacking capability becoming available to anyone, and using AI for good. Supporter content? We've got it! This week it includes a dive into post-quantum security and state-sponsored social…

Snake Oil Has an Expiration Date

It's Kris and Matt this week, and the conversation goes places. It starts with Matt going all-in on Apple and a leaked Claude Code source dump, then pivots into AI companies repeating social media's diversity-of-thought mistakes and why LLMs still can't beat "better than the average human" as a goalpost. The episode closes with a surprise detour into accounting, finance, and why double-entry bookkeeping is one of the original distributed systems. We've got supporter content, of course! This week that includes a home lab infrastructure rant about terrible BMC/IPMI systems, a nuanced deep dive…

Who's Afraid of Superintelligence?

We've got a full panel! In this episode, Kris, Matt, Steve, and Ian have a deep dive into superintelligence, AGI, and why the fear around them might say more about us than about AI. Steve draws a line from colonialism anxiety to alien invasion movies to superintelligence panic. Kris argues that a truly rational superintelligence would see that oppression consistently fails and cooperation wins. The conversation moves through whether AI is already oppressive, what it means for AI to be a subtle overlord, and why the real threats are mundane failures of leadership, not robot uprisings. We've…

The Joy of Building

This week Kris and Matt go full homelab. The conversation starts with Kris refreshing his dev setup: migrating NeoVim to 100% Lua, switching from ZSH to NuShell, and rethinking Tmux, all with the help of an LLM. The discussion then moves into hardware: Framework Desktop vs. Mac Studio, the RAM price explosion, 10G networking, WiFi with Private Pre-Shared Keys, and GPUs without display ports. The episode closes with a teaser for a future discussion on why Kris isn't worried about superintelligence. We've got supporter content, of course! This week that includes a mechanical keyboards deep…

The Least Contentious Proposal in the History of Go

Dylan's back this week joining Kris and Matt to tackle Go's UUID proposal (#62026). What Dylan thinksshould have been the least contentious proposal in the history of Go. The panel digs into the proposed API's shortcomings, the flawed ecosystem survey used to justify it, and why the Go team's library design philosophy doesn't hold up. The conversation builds into a broader critique of community dynamics and code of conduct double standards. As always, we've got supporter content! This week that includes the psychological cost of dismissive governance and who actually gets heard, the opaque…
