Exploring Extreme Programming
Extract Protocol lets us generalize our types. Context: You have a class (or other entity), and want to let another class stand in for it in some cases. You could make the other class a subclass. But this couples the Continue reading Extract Protocol Refactoring (Swift) – Elevate Common Behavior
Refactoring – “improving the design of existing code without changing its behavior” – is a key skill in developing software. These resources can help you improve.
Evolutionary design is a strategy to enable incremental delivery of capabilities. Consider two delivery strategies. In one, we plan everything we need, develop, then deliver when everything is ready. In the other, an incremental strategy, we first deliver a minimal Continue reading Evolutionary Design: Techniques and Example
Washington: The Indispensable Man, by James Thomas Flexner. My wife is on a quest to read biographies of each president. I don’t feel the same urge, but I did read one: George Washington.This treatment by James Thomas Flexner is a Continue reading Review – Washington: The Indispensable Man
This article (originally published in Better Software) explores generalization in TDD. The basic notion is that refactoring sets out to not change the behavior of code for any of its inputs, but TDD sets out to change behavior (in the Continue reading Refactoring and Generalization in TDD
How to Invent Everything: A Survival Guide for the Stranded Time Traveler by Ryan North. ISBN 073522014X. You’re tooling through time and your machine goes kaput. Ryan North has your back: You don’t have to wait hundreds or thousands of Continue reading Review: How to Invent Everything
When you clean up code, you often need refactorings that aren’t in any tool, and aren’t in Martin Fowler’s Refactoring catalog. You’re on your own. When this happens, think like a language lawyer and a logician. Language Lawyer and Logician Continue reading Home-Grown Refactorings – Be Careful!
Elm in Action, by Richard Feldman. ISBN 978-1617294044. (Amazon, Manning) This is a great introduction to the Elm language. It starts from basic concepts, and uses a running example of a photo browser to demonstrate many concepts: elm constructs, talking Continue reading Review: Elm in Action
How do stories fit in with other stories, or small stories with bigger ones? How can we move from skinny stories to richer ones? This is part of Scalability of stories. One way to think about story relationships is to Continue reading Connecting Stories
We’ll look at Test-Driven Development (TDD) and Test-Commit-Revert (TCR) in terms of how they work with frequent commits to source control. Test-Driven Development (TDD) Test-Driven Development is often described with this cycle: Red-Green-Refactor (or Red-Green-Gold, as I learned from Alex Continue reading TDD, TCR, and Frequent Commits
