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.

Rage Quit Stamina Theory
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 quit stamina” despite flaws in error reporting and dependency management. The group emphasized the importance of empathetic, fast code reviews and smaller PRs, arguing that culture and collaboration matter more than mythical “10x developers.” They also critiqued DHH’s claim that executives should be the least busy, framing it as privilege disguised as wisdom, while pointing out that rest and balance benefit everyone. The episode captured their signature mix of humor, industry critique, and camaraderie, closing with gratitude for 50 episodes and excitement for what’s next.Links:Giveaway: Anarchy Agile hats — enter at jardo.dev/anarchyagile“CEOs Are Publicly Boasting About Reducing Their Workforces With AI” – FuturismThe Pragmatic Engineer 2025 Survey: What’s in your tech stack?

Radiation Hardened (with Dave Gauer)
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 challenges to make complex systems programming concepts less intimidating. The conversation also explores Dave’s deep interest in the Forth language, the appeal of small, self-contained “microworlds” for learning, and his broader philosophy on sharing work, embracing whimsy, and building things that make programming joyful and approachable.Links:ZiglingsZigRustlingsForth ColorForthAlpine LinuxLynx browserWhy’s (Poignant) Guide to RubyLearning PerlThe Little SchemerMindstorms by Seymour Papert Steal Like an Artist by Austin KleonRatfactor.com – Dave Gauer’s personal website and blog.Forth in Space (section on Ratfactor) – Dave’s notes on how Forth has been used in radiation-hardened chips and space tech.Dead Code Podcast Links:MastodonXJared’s Links:MastodonXtwitch.tv/jardonamronJared’s Newsletter & WebsiteEpisode Transcript Hosted on Acast.

The software industry has a short memory. It warps good ideas, quickly obfuscating their context and intent. Dead Code seeks to extract the good ideas from the chaos of modern software development. Hosted on Acast. See acast.com/privacy for more information.
