Dead Code

• Brut-al Death (with David Bryant Copeland)

  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 eliminates free-form parameter hashes by injecting structured objects, mirrors HTML for form validations, and defaults to a strict, Postgres-only setup with non-nullable fields, required foreign keys, and built-in observability through OpenTelemetry and a strict Content Security Policy. Dave and Jared also discuss modern browser-based CSRF protections, the philosophy behind Brut’s defaults, and how Dave aims to refine it toward a 1.0 release with real-world apps and clear migration paths for Rails developers, positioning Brut as a lightweight, standards-aligned alternative within the Ruby ecosystem.Links:BrutSinatraHanamiSequelTachyonsTailwind CSSOpenTelemetryPostgreSQLMDN Web DocsElektron DigitaktAbleton LiveActiveRecordCoffeeScriptContent Security Policy (CSP)Rich Hickey – “Simple Made Easy” talkBurg.rbDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• God Class Funeral (with Adam Tornhill)

  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 cohesion, shows that healthy code enables teams to deliver features up to ten times faster with far fewer defects. They discuss how God classes become coordination bottlenecks, how behavioral code analysis reveals hotspots where improvement matters most, and why learning different programming paradigms sharpens thinking. Adam emphasizes that writing readable, well-named, modular code benefits both humans and AI tools—because clarity, consistency, and thoughtful naming make code easier to understand, maintain, and extend.Links:CodeSceneYour Code as a Crime SceneWorking MemoryGod Class / God ObjectDomain-Specific Languages (DSLs)Dead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Deserial Killer (with Matt Schwager)

  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 keep surfacing, often hidden in defaults or legacy code, as seen in Rails caching and RubyGems.org. Matt argues that this reflects a fundamental trade-off between ergonomics and security, suggesting alternatives like JSON are safer, though less convenient. He highlights mitigation strategies such as documentation, static analysis, and fuzzing with his tool Ruzzy, while also pointing to broader Ruby risks like eval misuse, SSRF, and supply chain issues. Jared reflects on the cultural tension in Ruby between ease of use and security, wondering if safer defaults could help developers avoid these common pitfalls.Links:Trail of Bits BlogRuby Marshal documentationPython Pickle documentationJSONYAMLTOMLMessagePackRails Caching GuideRubyGems.orgRubyGems source on GitHubRuzzy on GitHubAFL on GitHubSemgrep RegistryBlack Hat USA 2017 TalkDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Crushing Riffs (with Kasper Timm Hansen)

  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. The practice surfaces unknowns early, conserves mental stamina, and produces lightweight artifacts that can guide teams or even become executable prototypes. Kasper shares stories from client work, a RailsConf demo, and workshops showing how riffing helps uncover design flaws, generate stronger options, and make domain modeling more collaborative. He encourages developers to treat code like sketches, be less precious about early ideas, and embrace riffing as a fun, low-cost way to boost creativity and resilience in software design.Links:Spinel CoopRailsConf 2024 Talk (YouTube)RailsConf 2024 Slides (Speaker Deck)Kasper’s websiteKasper’s GitHubDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

• Fear-Driven Everything (with Justin Searls)

  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 to include product vision and context. The conversation touches on Agile and XP roots, consulting realities, and how AI coding agents can both accelerate and complicate work. The episode wraps with Justin encouraging blogging and direct connection, while Jared reflects on building a “grand unified theory” of how programmers decide their next step.Links:Sign up at jardo.dev/anarchyagile to enter the 50th episode giveaway!Test DoubleJustin Searls: Find his writing, projects, and podcast Breaking Change at justin.searls.coGrowing Object-Oriented Software, Guided by Tests by Steve Freeman & Nat PryceExtreme Programming Explained by Kent BeckThe Secrets of Consulting by Jerry WeinbergClojure REPLSolidusSwiftDataCloudKitCursorClaude CodeDead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.
