424: The Spectrum of Automated Processes for Your Dev Team: Joël shares his experience with the dry-rb suite of gems, focusing on how he's been using contracts to validate input data. Stephanie relates to Joël's insights with her preparation for RailsConf, discussing her methods for presenting code in slides and weighing the aesthetics and functionality of different tools like VS Code and Carbon.sh. She also encounters a CI test failure that prompts her to consider the implications of enforcing specific coding standards through CI processes. The conversation turns into a discussion on managing coding standards and tools effectively, ensuring that automated systems help rather than hinder development. Joël and Stephanie ponder the balance between enforcing strict coding standards through CI and allowing developers the flexibility to bypass specific rules when necessary, ensuring tools provide valuable feedback without becoming obstructions. by The Bike Shed

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

418: Mental Models For Reduce Functions: Joël talks about his difficulties optimizing queries in ActiveRecord, especially with complex scopes and unions, resulting in slow queries. He emphasizes the importance of optimizing subqueries in unions to boost performance despite challenges such as query duplication and difficulty reusing scopes. Stephanie discusses upgrading a client's app to Rails 7, highlighting the importance of patience, detailed attention, and the benefits of collaborative work with a fellow developer. The conversation shifts to Ruby's reduce method (inject), exploring its complexity and various mental models to understand it. They discuss when it's preferable to use reduce over other methods like each, map, or loops and the importance of understanding the underlying operation you wish to apply to two elements before scaling up with reduce. The episode also touches on monoids and how they relate to reduce, suggesting that a deep understanding of functional programming by The Bike Shed

417: Module Docs: Stephanie shares about her vacation at Disney World, particularly emphasizing the technological advancements in the park's mobile app that made her visit remarkably frictionless. Joël had a conversation about a topic he loves: units of measure, and he got to go deep into the idea of dimensional analysis with someone this week. Together, Joël and Stephanie talk about module documentation within software development. Joël shares his recent experience writing module docs for a Ruby project using the YARD documentation system. He highlights the time-consuming nature of crafting good documentation for each public method in a class, emphasizing that while it's a demanding task, it significantly benefits those who will use the code in the future. They explore the attributes of good documentation, including providing code examples, explaining expected usage, suggesting alternatives, discussing edge cases, linking to external resources, and detailing inputs, outputs, and pote 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

Meanwhile, Joël encourages folks to submit proposals for RailsConf. Together, Stephanie and Joël delve into the nuances of adapting to and working within new codebases, akin to aligning with a shared mental model or vision. They ponder several vital questions that every developer faces when encountering a new project: the balance between exploring a codebase to understand its structure and diving straight into tasks, the decision-making process behind adopting new patterns versus adhering to established ones, and the strategies teams can employ to assist developers who are familiarizing themselves with a new environment. by The Bike Shed

412: Vertical Slices: Joël shares a unique, time-specific bug he encountered, which causes a page to crash only in January. This bug has been fixed in previous years, only to reemerge due to subsequent changes. Stephanie talks about her efforts to bring more structure to her work-from-home environment. She describes how setting up a bird feeder near her desk and keeping chocolates at her desk serve as incentives to work more from her desk. Together, Stephanie and Joël take a deep dive into the challenges of breaking down software development tasks into smaller, more manageable chunks. They explore the concept of 'vertical slice' development, where features are implemented in thin, fully functional segments, contrasting it with the more traditional 'horizontal slice' approach. This discussion leads to insights on collaborative work, the importance of iterative development, and strategies for efficient and effective software engineering. by The Bike Shed

403: Productivity Tricks: Stephanie is engrossed in Kent Beck's Substack newsletter, which she appreciates for its "working thoughts" format. Unlike traditional media that undergo rigorous editing, Kent's content is more of a work-in-progress, focusing on thought processes and evolving ideas. Joël has been putting a lot of thought into various tools and techniques and realized that they all fall under one umbrella term: analysis. From there, Stephanie and Joël discuss all the productivity tricks they like to use in their daily workflows. Do you have some keyboard shortcuts you like? Are you an Alfred wizard? What are some tools or mindsets around productivity that make YOUR life better? 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
34 min listen
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
43 min listen
396: Build vs. Buy: Joël has been fighting a frustrating bug where he's integrating with a third-party database, and some queries just crash. Stephanie shares her own debugging story about a leaky stub that caused flaky tests. Additionally, they discuss the build vs. buy decision when integrating with third-party systems. They consider the time and cost implications of building their own integration versus using off-the-shelf components and conclude that the decision often depends on the specific needs and priorities of the project, including how quickly a solution is needed and whether the integration is core to the business's value proposition. by The Bike Shed
