Back around May 26, I created this branch. Today -- July 2 -- I've got the tests to pass.

I've reached the point where progress is clearly impossible. A bad decision a few weeks ago has reached it's inevitable conclusion. I've made a terrible mistake. About 1,000 lines of code -- and tons …

I'm struggling with brain cramps trying to understand something my past self wrote. Current me needs to go outside and do something that doesn't involve software or complexity. Sadly, current me is trying to make one small change and it feels like the software has passed out of the realm …

This was fun to read. It has some nice examples.

I submit that the order of presentation (S, O, L, I, D) is misleading. The acronym is fun, but awkward.

The SOLID design principles beat the design boundary issue to death. Here are the principles in my preferred order. (See https://www.linkedin.com/learning/learning-s-o-l-i-d-programming-principles)

1. Interface Segregation -- minimize the boundaries. Do this first.
2. Liskov Substitution -- keep the boundaries consistent. Do this for hierarchies.
3. Open/Closed -- keep the boundaries stable …

Sometimes we call them "Belt and Braces" solutions. As a former suspenders person who switched to belts, the idea of wearing both is a little like over-engineering. In the unlikely event of catastrophic failure of one system, your pants can still remain properly hoist. There's a weird, but defensible reason …
