Rust in Pieces (with Alistair Norman and Sofia Besenski)

On this episode of Dead Code, host Jared talks with Sofia Besenski and Alistair Norman of Super Good about DHH's 2026 Rails World keynote. In it, DHH announced that HEY is leaving Rails for six native apps and a Rust backend. He has called Rust hideous before, but he now argues that the language's looks don't matter because agents write the code and he doesn't read it. The panel doubts that six apps beat one good web app. Sofia warns that teams leaning on agents build up "cognitive debt" and lose track of how their systems work. Alistair says most people don't want more apps on their phones. All three dismiss DHH's lines-of-code numbers as meaningless. Jared reads José Valim's reply, which asks why DHH didn't use these tools to improve Rails itself, and the hosts point to other Rails World talks on Active Search, Herb, and Ractor safety that did move the framework forward.

Where the Bodies Are Buried (with Kerri Miller)

Jared talks with Kerri Miller, a Staff Engineer at GitLab, about Keela. It's her new open-source tool that finds unused code in Rails apps, and it's named after a UK police dog known for finding buried bodies. It began about three years ago as an attempt to cut GitLab's CI costs. Kerri didn't want a tool that deletes dead code all at once, so Keela uses regex to snapshot the methods it thinks are unused and fails the build when someone adds new dead code. An exclusion file handles false positives. So far the work has removed about 290 methods and saves GitLab around $150,000 a year in CI costs. Kerri has shipped five releases in six weeks, and partials are next on her list.

None Dare Refactor (with Noah Silvera)

Jared talks with Noah Silvera, a Super Good Software engineer and the show's most frequent guest, about treating requirements as negotiable rather than as literal instructions. Requirements reach engineers through a game of telephone, so she argues you have to go back to the client, understand the reasoning, and lead them toward better decisions they arrive at themselves. Engineers own the outcome and cannot hide behind "that's just what they told me." She makes the case for spikes, formal or informal, on the grounds that understanding an unfamiliar part of the system first is usually cheaper than fixing it later. Which decisions deserve that investment depends on how expensive they are to undo: design is easy to change in production, while data models require migrations and leave permanent gaps in what you collected. When a launch date will not move and Brooks' Law rules out adding people, the only real lever is cutting scope, which requires knowing what the business actually needs at launch. Her advice to newer developers is that working within constraints is the engineering problem, not an obstacle to it.

Bound for Valhalla (with Charles Nutter)

Charles Nutter has led JRuby for 20 years and still spends much of his time correcting the assumption that running Ruby on the JVM means writing Java. It doesn't. Rails and Hanami apps come over and run, and what you get underneath is world-class garbage collection, real parallel threads instead of 50 forked processes, the Maven Central ecosystem, and profilers you can attach to a live production server. He tells Jared how a $50 Ruby conference in 2004 pulled him out of Java enterprise work and into a project that had been idle since 2001. They also get into the startup time problem and how much recent JVM work has closed it, the compatibility jump through JRuby 10 and 10.1, invoke dynamic, fibers on virtual threads, and what Panama, Valhalla and Project Babylon could mean for Ruby. Charles now funds the work himself through Headius Enterprises after Red Hat's sponsorship ended.

Dragged Into Done (with Nikhil Suresh)

Host Jared Norman talks with Nik Suresh, who runs Hermit Tech, an extreme programming data consultancy in Melbourne, about why Scrum fails. Nik argues Scrum spread through dishonest marketing (Sutherland's "twice the work in half the time" promise) and that its rituals amplify bad management rather than fix it, from Fibonacci story points that are really just time estimates to one-hour standups he's seen more often than the correct version. His core point is that the map is not the territory: Jira boards and status PowerPoints give executives a simulated cockpit rather than an accurate picture, and he admits he once moved cards to done without doing the work and nobody noticed. He advocates treating any deadline slip as evidence the whole estimate was wrong, paying attention to morale and sick days as the real project signals, and tells engineers stuck in dysfunctional standups to just quit before the environment warps them. His closing lesson is that dropping Scrum alone won't help, since the conditions that produced it will just produce the next silly framework unless teams honestly ask how they came to follow a process on faith.

No More Magic (with Nithin Bekal)

On this episode of Dead Code, Jared talks with Nithin Bekal, a longtime Ruby developer at Shopify, about Sapphire, his hobby programming language: a gradually typed, object-oriented language inspired by Ruby but stripped of metaprogramming magic, implemented in Rust, with features admitted only if he'd use them in production code. Nithin built much of it with LLM coding agents, even prompting from his phone after his laptop died, and now has 10,000 to 15,000 lines of Rust he doesn't fully understand, so he plans to scale back to asking agents questions rather than letting them drive, a struggle Jared relates to after throwing away his own fully vibe-coded OCaml compiler before hand-building his ML-style language, Shroom. Nithin prioritized tooling early because developer experience is what he most wants to learn, cites the LLM-fueled wave of hobby languages like Matz's Spinel and Steve Klabnik's Rue as motivation, advises aspiring language builders to just dive in since parsing is more approachable than it looks, and plans a docs generator as Sapphire's first real codebase.

Twilight of the Object God (with Ismael Celis)

On Dead Code, Jared talks with returning guest Ismael, a London-based developer who came to programming from fine arts, about event sourcing, CQRS, and the Ruby stack he's built around them. Ismael frames event sourcing as thinking in time rather than space: instead of persisting current state, you keep an append-only log of facts and reduce over it to derive any view you need, which makes gnarly e-commerce discount rules collapse from a sprawling schema into small functions over a flat event stream. His stack includes Sourced (event sourcing), Sidereal (a command-driven web toolkit where forms fire commands into a queue and workers push re-rendered templates back over SSE via Datastar, and notably it isn't tied to event sourcing at all, since the only interface is a plain command struct), and Step (a DSL that yields a running REST API plus OpenAPI docs, tests, clients, and MCP tools from one definition). He's now reworking Sourced around Dynamic Consistency Boundaries, abandoning DDD's aggregate-root God streams in favor of loading only the events needed to validate a specific decision, which cuts lock contention, because consistency is really about the state you used to make a decision. His advice: use Rails Event Store for real work, but to actually understand it, skip frameworks, put event structs in an array, and reduce.

Bloom of the Undying (with Tim Riley)

Tim Riley returns to discuss the launch of Hanakai, a new organization unifying the Hanami, Dry, and ROM projects into a cohesive Ruby ecosystem focused on modern architecture, collaboration, and community. He explains how Hanami 3.0 represents the culmination of years of work, introducing rebuilt mailers, Minitest support, built-in internationalization, significant performance improvements, better logging, and a preview of a language server, while also making the framework more extensible for future growth. The conversation also explores the realities of sustaining mature open source projects through sponsorship, transparent development, and contributor-friendly practices, along with Hanakai’s commitment to inclusive community values, technical diversity, and giving Ruby developers more ways to build applications beyond the traditional Rails path.

Altars of Append (with Ted M. Young)

Ted M. Young joins Jared to discuss Extreme Programming, predictive test-driven development, event sourcing, and teaching software practices through board games. Ted explains how predictive TDD encourages developers to anticipate exactly how a test will fail, leading to deeper understanding, faster feedback, and smaller development steps. He also argues for thinking about tests as either I/O-free or I/O-dependent rather than unit or integration tests, a distinction that naturally supports cleaner architectures and more maintainable code. The conversation explores Ted’s growing enthusiasm for event sourcing, which he sees as a simpler way to model state changes, preserve history, and reduce complexity around persistence and caching. They also discuss his TDD board game, which has become an effective tool for teaching collaboration, pairing, and software development concepts. The episode closes with a look at AI’s impact on software craftsmanship, with Ted expressing concern that developers may learn less by outsourcing problem-solving to LLMs, while remaining optimistic that core XP practices like small steps, clear goals, and rapid feedback will continue to matter—and may be more relevant than ever.

Toxic Deluge (with Joan Westenberg)

Jared talks with Joan Westenberg about her essay “The Hacker News Tar Pit” and the misconception that AI-powered vibe coding can easily replace established products. Joan argues that while AI can generate software, it cannot recreate the communities, culture, trust, moderation systems, shared history, and network effects that make platforms like Hacker News valuable. The conversation explores how online communities form organically, why moderation and human labor matter more than code alone, and how AI-generated spam is changing the nature of internet communities. They also discuss open source software, the flood of vibe-coded projects, and the psychological effects of constantly comparing your work to what others are building online. Joan ultimately argues that developers should build things because they genuinely want them to exist, not because they expect to disrupt incumbents, while Jared closes by reflecting on an AI-generated compiler he built that worked technically but failed to inspire the long-term interest needed to turn it into a real project.
