Code with Jason291 - Joel DrapperIn this episode I talk with Joel Drapper about defect-free development—not just automated testing, but the full spectrum: linting, static typing, database constraints, and especially runtime assertions. Joel's library Literal lets you define type expectations that blow up immediately when violated, catching bugs before they spread.Links:literal.funphlex.funjoel.drapper.meNonsense Monthly

Die nächste Urlaubsphase ist vorbei und beide berichten von ihrer Woche. Sandra beschäftigte sich mit JPMS, DHCP-Konfigurationen und Azure Virtual Desktop. Bei Daniel war es etwas ruhiger, aber sein Signal-Migrationsprojekt machte Fortschritte.
Bei Ramsch aus dem Modem geht es um Codeberg Pages, Liquibase, Lego Gameboy und die Hades 2 Ankündigung.
Für diese Folge hat sich Daniel mit der aktuellen Situation in der Ruby-Community beschäftigt. Was heißt das für andere Open-Source Communitys?
Zum Schluss gibt es noch eine Podcast-Empfehlung.

Code with Jason268 - Joel DrapperIn this episode I talk with Joel Drapper about open source development, the joy of coding without constraints, AI tools like GitHub Copilot, and our shared discomfort with the phrase "duplication is better than the wrong abstraction." We explore abstraction, technical debt versus "technical poison," and our mutual search for high-quality work environments.Joel Drapper on LinkedInPhlexNonsense MonthlySaturnCI

Dead CodeUndefined and Unforgiven (with Joel Drapper and Lucian Ghinda)In this episode of Dead Code, Jared is joined by Lucian and returning guest Joel to debate a classic Ruby dilemma: whether to access instance variables directly or use getter methods. Lucian advocates for getters, especially in large, fast-changing codebases, arguing they help catch subtle bugs and improve maintainability, as well as insights drawn from his time at Cookpad and the Short Ruby newsletter. Joel, while appreciating the clarity and performance of direct access, introduces his gem strict_ivars, which raises runtime errors for undefined variables, offering a hybrid solution that improves safety without sacrificing flexibility.

Crossed WiresAdventures in Programming
When we think of programming, we may tend to think of Matrix-esque nerds sat in front of green-on-black screens absorbed in code that makes less sense than a chocolate teapot, or we may think of super-star game developers bashing out the latest GTA or similar.
The reality is that programming is very much a problem solving exercise, and languages like Ruby provide a set of tools for how to map out logic and present results to the average computer user.
