421: The Idealistic vs. Pragmatic Programmer
April 2nd, 2024 | 41 mins 1 sec
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.

Together, Stephanie and Joël address a listener's question about replacing the wkhtml2pdf tool, which is no longer maintained.
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.
