to get to the clearest design, it's ok always be shifting things (methods, values, entities, aggregates) to where they make the most sense in the model; reflect on ISP, cohesion, coupling, on adding/removing layers, on simplicity, on asking more questions

where would be the best home for a piece of logic?
a) in the object that knows the business rules
b) in the object that has the data
there might be another option:
c) in the object that has the data, and is injected with the rules (in a Strategy), by the object that knows the rules
Domain Driven Design (DDD) made plain broke down to the bone gristle. cus i need that science to level up my code, but miss me with all the stuffy acronyms and jargon. 🧵
domain
- the actual problem
- what we're trying to solve with the code for the user
- the set of problems that the users ask the developers to solve
- the subject matter
domain driven
- problem focused
- to stay focused on the actual problem
For me, when the need for a new language, library, framework, shiny thing, etc pops up - i find that i usually take the same general steps
and the 7-bullet list i jotted down in my notes became this thread:
1. pick a language, any language. or framework, library etc.
no tech is perfect. don't sweat it the choice too much. they all have pros and cons - but do try to pick one that has good community adoption so you can get help when you run into blockers

never when you just foresee that you need them." - Ron Jeffries
i feel attacked 🙄
(over-abstraction is one of my guilty pleasures) 😅
like, sometimes i'll take that advice to "code to the interface" to the extreme, just cus i can, and i'll make everything an interface. what you can do with polymorphism and dependency injection is fun ...
but man is it an over-abstraction time suck when trying to just focus on "keeping it simple" KISS minimum viable product. gotta draw the line somewhere and make concrete classes and move forward ...
