Dead Code

• Deterministic Simulation (with Stevan)

  In this episode of Dead Code, Jared talks with Stevan about building reliable distributed systems using Erlang-inspired design patterns. Stevan shares how his background in functional programming and formal verification led him to simulation testing—a deterministic approach to testing distributed systems that avoids the flakiness of traditional CI environments. He emphasizes that Erlang’s true innovation lies not in lightweight processes, but in its structured behaviors (like gen_server and supervisor), which make systems easier to reason about, test, and verify. These behaviors support a more disciplined approach to concurrency, enabling reproducible fault injection and better simulation frameworks. Stevan advocates for programming languages that natively support deterministic testing and model checking, suggesting that the future of distributed systems lies in building on these structured, verifiable foundations.Links:Stevan’s BlogErlangElixirAgdaIdrisTLA+RocJepsenAntithesisBEAMLet it crash philosophyDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Brutality of Behaviour (with Carson Gross)

  In this episode of Dead Code, Jared interviews Carson Gross, creator of HTMX, about the principle of Locality of Behavior (LoB) and its role in web development. Carson explains that HTMX enhances HTML rather than replacing it like modern JavaScript frameworks, offering a simpler, hypermedia-driven approach ideal for use cases like e-commerce. He critiques the traditional emphasis on Separation of Concerns, arguing that keeping behavior close to markup improves maintainability and avoids “spooky action at a distance.” Carson acknowledges trade-offs between LoB, DRY, and SoC, emphasizing the importance of context-based decision-making. He and Jared also discuss broader software trends, advocating for deeper modules, simpler APIs, and a pragmatic, less ideological approach to coding as the industry evolves.Links:HTMX WebsiteHTMX Essays (especially Locality of Behavior and When to Use Hypermedia)grugbrain.devHypermedia Systems BookRichard Gabriel’s “Worse Is Better” EssayMozilla Developer Network (MDN)John Ousterhout’s A Philosophy of Software DesignThe Uncle Bob vs. John Ousterhout ArgumentBig Sky Software (Carson’s Company)HyperscriptDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• GOTO Precedence Hell (with Noratrieb)

  In this episode of Dead Code, Jared chats with Nora, a Rust contributor, about operator precedence and the trade-offs between code clarity and conciseness across programming languages. Nora, inspired by her blog post “Don’t Play the Precedence Game,” explains how languages like C and Rust handle operator order differently, particularly around equality and bitwise operations, which can lead to subtle, hard-to-spot bugs. She advocates for using parentheses generously to make intent explicit, even if some consider it “noisy,” and highlights how tools like linters and formatters approach optional syntax differently. They also touch on Ruby’s permissive style, Lisp’s avoidance of precedence via prefix notation, and broader lessons for language design—ultimately agreeing that clarity should win when it matters, and that different languages cater to different developer mindsets.Links:“Don’t Play the Precedence Game” RustC Programming LanguageRubyLispGoRescriptrustfmtClippyPrettierNora’s Website Nora’s MastodonNora’s GitHub Dead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Cursed Return (with Nicole Tietz-Sokolskaya)

  In this episode of Dead Code, Jared speaks with software engineer Nicole Tietz-Sokolskaya about the ethical complexities of large language models (LLMs). Nicole shares her mixed experiences with LLMs—finding brief personal value but little long-term usefulness in her work—and critiques their environmental impact, reliance on questionable training data, and potential to concentrate power among major tech companies. She raises concerns about consent, bias, and the quality of generated code, while also acknowledging LLMs’ potential in accessibility and trust and safety roles. Ultimately, both Nicole and Jared advocate for a values-driven approach to technology, urging developers to critically evaluate the tools they use and the broader implications of their choices.Links:Mastodon: [email protected]’s BandcampCan I Ethically Use LLMs?Talon Voice SoftwareRecurse CenterDeconstruct ConfAMP ProjectDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Frozen to Death (with Kevlin Henney)

  In this episode of Dead Code, Jared talks with Kevlin Henney about the importance of immutability in software development, particularly as a strategy for reducing bugs related to state and concurrency. Kevlin explains that while many programming languages default to mutable state, treating state change as a privilege—not a right—can lead to more maintainable, less error-prone code. He discusses how immutability strengthens encapsulation, simplifies reasoning about systems, and avoids issues like race conditions and deadlocks, especially in multi-threaded environments. Kevlin also emphasizes that these design choices are architectural, not just implementation details, and that teams benefit from shared philosophies around state management. The conversation ties into broader programming culture and offers practical insights for developers, especially those working in languages like Ruby, where mutability is common but evolving.Links:Kevlin Henney’s article – “Restrict Mutability of State”Book – 97 Things Every Programmer Should KnowOpen source repo with contributionsOverflow collection curated by Shirish Padalkar (includes the “Restrict Mutability of State” essay)RubyConf Mini Providence Talk – Immutable Data StructuresRailsConf Talk – Immutable Objects in Practice@Kevlin on Bluesky@[email protected] Henney on LinkedInDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.
