421: The Idealistic vs. Pragmatic Programmer: Stephanie revisits the concept of "spiking"—a phase of exploration to determine the feasibility of a technical implementation or to address unknowns in feature requests—sharing her recent experiences with a legacy Rails application. Joël brings a different perspective by discussing his involvement with a client project that heavily utilizes the dry-rb suite of gems, highlighting the learning curve associated with adapting to new patterns and libraries. Joël used to be much more idealistic and has moved to be more pragmatic. Stephanie has moved the other way. So together, Stephanie and Joël engage in a philosophical discussion on being an idealistic versus a pragmatic programmer. They explore the concept of programming as a blend of science and art, where technical decisions are not only about solving problems but also about expressing ideas and building shared understandings within a team. by The Bike Shed

The episode's main topic revolves around the concept of multidimensional numbers and their applications in software development. Joël introduces the idea of treating objects containing multiple numbers as single entities, using the example of 2D points in space to illustrate how custom classes can define mathematical operations like addition and subtraction for complex data types. They explore how this approach can simplify operations on data structures, such as inventories of T-shirt sizes, by treating them as mathematical objects. by The Bike Shed

398: Developing Heuristics For Writing Software: Want a cool cucumber salad? Joël's got you covered. Stephanie has evolved and found some pickles she enjoys. Experienced programmers use a lot of heuristics or "rules of thumb" about what makes their code better. These aren't always true, but they work in most situations. Stephanie and Joël discuss a range of heuristics, how to use them, how to come up with them, how to know when to break them, and how to teach them to more junior devs. by The Bike Shed

397: Dependency Graphs: Stephanie is consciously trying to make meetings better for herself by limiting distractions. A few episodes ago, Joël talked about a frustrating bug he was chasing down and couldn't get closure on, so he had to move on. This week, that bug popped up again and he chased it down! AND he got to use binary search to find its source–which was pretty cool! Together, Stephanie and Joël discuss dependency graphs as a mental model, and while they apply to code, they also help when it comes to planning tasks and systems. They talk about coupling, cycles, re-structuring, and visualizations. by The Bike Shed
