Thoughts, tutorials, and tales from the digital frontier. Lessons learned and wisdom shared.
Second in the legacy-code series. I wanted to write one test and couldn't, because testing one piece meant standing up the whole app. On why "add tests later" is a lie until you carve seams, and why splitting a monolith isn't tidiness.
Read moreYou rent it. And the whole thing runs on a renewal you probably never see. Here's how it works, and how to make sure the name your business runs on is actually in your hands.
Read moreFirst in a three-part series on cleaning up legacy code. A bug that compiled clean and broke nothing until a page loaded in a browser, because the data structure at its centre had no type and no owner. On implicit contracts, and why the compiler can't save you from one.
