He explains how Hanami 3.0 represents the culmination of years of work, introducing rebuilt mailers, Minitest support, built-in internationalization, significant performance improvements, bette...

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...

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...

In this episode of Dead Code, Kasper Timm Hansen shares how his post–Rails Core work focuses on small, high-impact Ruby gems built around clear “concepts” rather than loose abstractions, helping developers model domains more effectively and avoid bloated ActiveRecord models. He discusses tools like Associated Objects and ActiveJob::Performs, which simplify structuring data and background jobs whil...

In this episode, Jared talks with security researcher Lyra Rebane about pushing CSS far beyond its reputation as a simple styling language, exploring how modern features like nesting, advanced selectors, and state-based logic enable complex interactivity without relying on JavaScript. Inspired by experiments on Cohost, Lyra created projects like a fully CSS-based clicker game and even an 8086 CPU...

In this episode of Dead Code, Jared talks with developer Dave Copeland about his article “The Death of the Software Craftsman,” which reflects on how AI coding tools are reshaping the role of programmers. Copeland describes a personal reckoning with whether traditional programming skills still matter in a world where AI can generate large amounts of code. He outlines three possible responses for d...

Sean Goedecke contrasts generic design advice (principles and patterns not grounded in a specific codebase) with concrete design (decisions shaped by the real code, constraints, and existing “prior art”), arguing you can’t meaningfully design software you don’t work on because you lack the context to make implementable calls. Generic advice has its place (greenfield work, company-wide guardrails),...

Jared interviews veteran programmer and author Russ Olsen about updating Eloquent Ruby for the last 15-ish years of Ruby evolution, from how he discovered Ruby while trying to teach his young son to code (anything but Java) to how Rails suddenly made Ruby mainstream and pushed him into writing. They unpack what “eloquent” Ruby means: solving problems with minimal fuss, staying concise but clear, a...

Jared interviews CS and cybersecurity grad student Daniel Fichtinger about “slopware” in open source. These are projects, often boosted by AI, that perform legitimacy with buzzwords, emoji feature lists, templates, donation links, and sweeping claims, while the underlying code is messy, over-scoped, or not actually delivering what the README promises. Daniel argues the issue is not simply “bad cod...

Jared talks with Stephen Margheim about a “missing” middle layer in modern design systems: reusable CSS affordances that sit between Tailwind utilities and full components. Stephen shares how building a no-JavaScript half-star rating input (radio buttons + labels + SVG + careful hover/layout CSS) reinforced his bias toward solving problems with the smallest toolset to avoid incidental complexity a...

In this episode, Jared is joined by Samir Talwar to talk about why “programming peaked” and how the developer experience has arguably regressed over the last 15 years—from losing powerful IDE refactoring workflows to the ways pull requests can turn into delayed integration. They dig into what teams lost when testing became “everyone’s job,” why reviews often get stuck in surface-level diff comment...

Jared talks with Sabine Schmaltz, an OCaml Developer Advocate at Tarides, about how she went from learning Standard ML in a demanding university course to getting hired for an OCaml role despite only having written “Hello, World,” and what she’s building now: FeedMansion, a tool to improve multi-account social posting and make OCaml community content more engaging with better summaries/teasers. Sa...

Jared interviews Steve Klabnik (Rust author and longtime OSS contributor) about JJ (Jujutsu), a newer version control system that can operate on Git repos via pluggable backends so you can adopt it locally without forcing teammates to switch, while getting a simpler, more flexible workflow. Steve explains JJ’s core shift: no staging/index—your working copy is effectively a mutable commit you shape...

In this episode, GitHub engineer Joel Hawksley breaks down the evolution of GitHub’s UI architecture—from Rails views to ViewComponent to React—and the tradeoffs behind each step. ViewComponent emerged as a practical, backwards-compatible way to eliminate duplicated UI logic in GitHub’s massive Rails monolith, ultimately supporting thousands of components and becoming a key driver of consistency a...

In this Dead Code episode, Jared and ReScript contributor Josh Vlk explain why ReScript is a strongly typed, sound language for web development that compiles to JavaScript, offers first-class React support, and favors a “one right way” approach (built-in formatter, no linters) over TypeScript’s configurable sprawl. They trace its evolution from Reason/BuckleScript to today’s standalone ReScript, w...

In this episode, Dave Copeland discusses Brut, his Ruby web framework built atop Sinatra that prioritizes “simple over easy” design principles. Brut replaces traditional MVC with pages, forms, and handlers, uses Flex for HTML generation, Sequel for database access, and lightweight tools like BrutCSS and BrutJS for styling and interactivity, emphasizing direct alignment with web standards. It elimi...

Jared talks with Adam Tornhill, founder of CodeScene, about the psychology of programming and how understanding human cognitive limits leads to better software. Adam explains that since working memory can only juggle a few items at once, developers must rely on chunking and good abstractions to manage complexity. His Code Health metric, based on detecting “ugliness” like long functions and low coh...

Jared sits down with Trail of Bits security engineer Matt Schwager to discuss the persistent security risks of Ruby’s Marshal library. Matt explains that while Marshal (and Python’s Pickle) makes serialization simple and fast for tasks like caching, its “serialize anything” design has led to over a decade of recurring vulnerabilities. Despite repeated patches, new bugs and exploitation gadgets kee...

In this Dead Code episode, Jared talks with longtime Rubyist and former Rails Core member Kasper Timm Hansen about “riffing,” a sketch-first approach to software design. Instead of jumping straight into migrations and production code, Kasper opens a scratch Ruby file—mixing real and pseudo-code with short prompts—to explore names, relationships, and system flow without worrying about correctness....

On this episode of Dead Code, Jared talks with Justin Searls, co-founder of Test Double, about programming workflows, decision-making, and the evolving role of developers. They explore how the order and tempo of thought matter more than static code, why tackling the riskiest problems first can shape better outcomes, and how Justin’s idea of the “full-breadth developer” expands a programmer’s role...

The 50th episode of the Dead Code Podcast brought Karl Weber, Jared Norman, Benjamin Wil, Sofia Besenski, and Noah Silveira together to mark the milestone with sharp, funny, and critical takes on the state of tech. They skewered CEOs bragging about AI-driven layoffs as short-sighted profiteering, questioned the hype fueling the AI bubble, and praised Ruby and Rails for extending developers’ “rage...

In this episode of Dead Code, Jared interviews Dave Gauer, creator of the Ziglings project—a whimsical, hands-on tutorial for learning the Zig programming language. Dave shares how Ziglings began as a personal learning tool and grew into a widely loved resource, especially among younger developers. He emphasizes the value of learning in public, blending humor, accessibility, and bite-sized challen...

In this episode of Dead Code, Jared and guest Mond explore how James C. Scott’s concepts of legibility, metis, and episteme apply to tech interviews, arguing that standardized hiring processes prioritize what’s easy to measure over what truly reflects engineering skill. They critique the over-reliance on algorithmic interviews, noting that senior engineering work often depends on tacit knowledge—m...

In this episode of Dead Code, Jared speaks with Jens Oliver Meiert and Fabien Basmaison, co-maintainers of CSS Naked Day, a long-standing web tradition that invites developers to strip CSS from their websites for one day to emphasize semantic HTML, accessibility, and the separation of concerns in front-end development. Originally launched in 2006, the event encourages developers to reflect on the...

In this episode of Dead Code, Jared interviews Ivo Anjo, a Ruby performance expert at Datadog, about Ruby’s concurrency model and his work improving visibility into it. They discuss the Global VM Lock (GVL), which simplifies Ruby’s internals but hinders multithreading, and explore the promise and current limitations of M:N scheduling, now partially implemented via Ractors in Ruby 3.4. Ivo created...
