CUPID - for joyful coding

Some codebases are nicer to work with than others. This is true for applications, services, libraries, frameworks, even programming languages themselves. Is this a purely personal choice or are there universal characteristics of software that can make code a joy to work with? Daniel has been thinking about this for a long time, especially since he poked a stick at [the SOLID principles](https://www.baeldung.com/solid-principles) for fun a few years ago and people came after him with pitchforks. His recent post about [why he feels SOLID is outdated](https://dannorth.net/2021/03/16/cupid-the-back-story/) ended up on the front page of Hacker News! Now he has codified his thoughts into his own pithy five-letter acronym, CUPID: Composable, Unix philosophy, Predictable, Idiomatic, Domain-based. Why these characteristics, what do they mean, and why should you care? Can they improve your coding experience or is this just more programmer navel-gazing?
