360: ActiveRecord Models

November 1st, 2022  |  28 mins 37 secs

Fellow thoughtboter Sarah Lima joins Joël to discuss an issue Sarah had when she was doing a code review recently: making HTTP requests in an ActiveRecord model. Her concern with that approach was that a class was having too many responsibilities that would break the single-responsibility principle, and that it would make the class hard to maintain. Because the ActiveRecord layer is a layer that's meant to encapsulate business roles and data, her issue was that adding another responsibility on top of it would be too much. Her solution was to extract a class that would handle the whole HTTP request process.

359: Serializers

Chris Toomey is back! (For an episode.) He talks about what he's been up to since handing off the reins to Joël. He's been playing around with something at Sagewell that he enjoys. At the core of it? Serializers.

358: Class Methods

October 18th, 2022  |  40 mins 40 secs

Inspired by a Slack thread, Joël invites fellow thoughtbotter Aji Slater on the show to talk about when you should use class methods and when you should avoid them. Are there particular anti-patterns to look out for? How does this fit in with good object-oriented programming? What about Rails? What is an "alternate constructor"? What about service objects? So many questions, and friends: Aji and Joël deliver answers!

357: Notetaking For Developers

October 11th, 2022  |  30 mins 55 secs

Joël is joined by Amanda Beiner, a Senior Software Engineer at GitHub, who is known for her legendary well-organized notes. They talk about various types of notes: debugging, todos, mental stack, Zetelkasten/evergreen notes, notetaking apps and systems, and visual note-taking and diagramming too!

356: The Value of Specialized Vocabulary

September 27th, 2022  |  39 mins 20 secs

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.

355: Test Performance

September 20th, 2022  |  42 mins 44 secs

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.

354: The History of Computing

September 13th, 2022  |  31 mins 16 secs

Why does the history of computing matter? Joël and Developer at thoughtbot Sara Jackson, ponder this and share some cool stories (and trivia!!) behind the tools we use in the industry.

353: Mental Models

September 6th, 2022  |  38 mins 22 secs

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.

352: Case Expressions

August 30th, 2022  |  32 mins 23 secs

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?

351: Learning in Public

August 23rd, 2022  |  37 mins 7 secs

It's Joël's first episode as host of The Bike Shed! 👋

Joël has fellow thoughtbotter Steve Polito join him to talk about the benefits and drawbacks of "learning in public" and how there are many, many different ways to do it.
