RE: https://mastodon.social/@MichDdev/117406436791405007 Okay, I wrote the #kotlin sealed interface love letter blog post! https://michd.me/blog/a-love-letter-to-kotlin-sealed-interface/ It covers explaining the qualities of the sealed interface, and a number of real world examples of how it's massively simplified systems. I muse a bit about some architectural principles I've learned over time too and make some recommendations. I hadn't really blogged about software engineering in over a decade somehow; it was nice to get back to it. #softwareengineering #androiddev
