Guest and fellow thoughtbotter Stephanie Minn and Joël chat about how the idea of specialized vocabulary came up during a discussion of the Ruby Science book. We have all these names for code smells and refactors. Before knowing these names, we often have a vague sense of the ideas but having a name makes them more real. They also give us ways to talk precisely about what we mean. However, there is a downside since not everyone is familiar with the jargon.

Guest Geoff Harcourt, CTO of CommonLit, joins Joël to talk about a thing that comes up with a lot with clients: the performance of their test suite. It's often a concern because with test suites, until it becomes a problem, people tend to not treat it very well, and people ask for help on making their test suites faster. Geoff shares how he handles a scenario like this at CommonLit.

Mental models are metaphors that help us understand complex problems we work on. They can be a simplified roadmap over an infinite area of complexity.
How does one come up with mental models? How are they useful? Are they primarily a solo thing, or can they be used to communicate with the team? What happens when your model is inaccurate? Today, Joël is joined by Eebs Kobeissi, a Developer and Dev Manager at You Need a Budget, to discuss.

As developers, we care a lot about code quality. How do we know how good is good enough? When do we stop improving code? Alternatively, when working on code that's really bad, how much do you improve it before calling it a day? thoughtbot's Stephanie Minn joins Joël to chat about this and case expressions: We recently discussed these as part of thoughtbot's RubyScience reading group. Are case expressions bad? Are they equivalent to multi-way conditionals? When do you use polymorphism?
