In this Dead Code episode, Jared Norman hosts Aji Slater, Development Team Lead at thoughtbot, to discuss “incremental automation,” a concept that advocates for gradually automating tasks by refining them with small steps rather than investing large amounts of time upfront. Aji explains that capturing each step of repetitive tasks enables developers to tweak processes over time, which reduces friction and saves effort without disrupting workflows. Starting with “do-nothing scripts” that print steps or copy commands, developers can progressively automate, building efficiencies that enhance productivity and prevent burnout. Aji also emphasizes sharing these incremental improvements across teams, so everyone benefits from the refined workflows without repeating the same manual work.

In this Dead Code episode, Jessica Kerr (Jessitron) joins host Jared Norman to explore the evolving nature of experimentation and learning in software development. Jessica reflects on her shift from valuing software’s determinism to embracing the unpredictability of distributed systems and human factors. She explains that traditional scientific methods, like A/B testing, often fall short in complex, socio-technical environments, where dynamic learning and observing real-world impacts are crucial. At Honeycomb, she practices a holistic approach to experimentation, viewing each system and team as a “symmathesy”—a mutual learning environment where insights flow between developers and the software. Jessica emphasizes that continuous improvement relies on knowledge sharing and storytelling within teams, urging developers to approach retrospectives as genuine feedback loops to refine processes, connect with teammates, and foster growth.

In this episode of Dead Code, host Jared Norman talks with Andrew Atkinson, author of High Performance Postgres For Rails, about the benefits and recent updates to Postgres. Andrew shares why he prefers Postgres for its reliability, extensibility, and independence from corporate control, making it ideal for applications with complex or fluctuating data needs. They delve into Postgres 17’s new features, like JSONB functions for querying JSON as if it were relational data, improved MERGE operations for simplified upserts, and new returning clauses. Andrew’s book is designed for application developers seeking to optimize performance and security beyond ORM abstractions, with practical examples to help them harness Postgres’s full potential. Jared and Andrew agree that Postgres’s robust tools can elevate an application’s reliability, especially in high-demand scenarios like e-commerce, encouraging developers to explore its depth.

In this Dead Code podcast episode, Jared Norman interviews Chael Wright-Munn (ChaelCodes) about the benefits of working openly through activities like live streaming and contributing to open-source projects. Chael emphasizes how creating a "library of examples" through public coding can enhance a developer’s skills, build their professional network, and preserve their achievements beyond their current job. She offers practical advice on starting a stream, such as using OBS software, focusing on community building, and engaging in structured projects like Hacktoberfest. The discussion highlights the value of maintaining a visible presence in the tech community, whether through streaming, open-source contributions, or other public-facing efforts, as a way to retain knowledge and showcase work, even across job changes.

In this episode, Jared speaks with Coraline Ada Ehmke, a veteran software developer and creator of the Contributor Covenant and Hippocratic License, about the ethics of open-source software. Coraline discusses common justifications developers use to avoid accountability for the potential harm their software may cause, such as the "freedom zero" argument advocating for unrestricted use of software and the belief that access to the source code ensures ethical behavior. She critiques these views, emphasizing that developers must consider the societal impact of their work and set clear ethical boundaries. Coraline encourages the use of a "negative roadmap" to define what developers refuse to build, urging them to think critically about the harm their technology may enable. The episode concludes with Coraline promoting her work with the Organization for Ethical Source and her upcoming book, which explores responsible tech practices.

In this episode of Dead Code, J.B. Rainsberger discusses the pitfalls of integrated tests, calling them a "scam" due to their tendency to complicate rather than solve testing problems. He advocates for writing smaller, more focused tests, like unit tests, to simplify debugging and avoid tangled code. J.B. emphasizes that test-driven development (TDD) should be flexible, guiding developers to test based on what they're afraid might break, rather than following rigid rules. He introduces the concept of four stages of TDD, where developers evolve from focusing on bug prevention to refining their approach based on experience, adapting their testing strategy to different contexts while maintaining the core principle of starting with a failing test.

In this episode of Dead Code, Jared interviews Kevin Newton, Staff Software Engineer at Shopify, about his work on Ruby's new parser, Prism. Kevin explains how Prism was created to address the limitations of Ruby's original parser by providing a portable, error-tolerant solution that unifies the ecosystem, replacing multiple outdated parsers used across different tools. They discuss the challenges of parsing Ruby's complex syntax, including quirky features like heredocs and regular expressions, and how Prism was designed for better control and performance. Kevin emphasizes the community-driven effort behind the project, making it more accessible to contributors, and shares how Prism will advance Ruby tooling in future releases.
