Pointing to a list makes the problem look too easy, because it’s such a clearly defined abstraction. Of course a linked list mostly doesn’t need to change—it’s an easy problem.

Give me a definition of good code that applies to:

- the standard library

- a gui toolkit

- the kernel

- the apps built on top of vendor provided gui toolkits that change

- a web application backend

- a web application front-end

- a database

- more things I’m forgetting
