Human minds, programming, and the "caching problem"
I like to view programming languages in terms of how they allow me to deal with complexity, keeping as much stuff in my head at once:
- Lisp: great for building up the language from the bottom and extending towards an application domain. The new application "programming language" is higher level and the remaining part of a system is more concise code and easier to keep track of.
- Ruby: concise, so programs are much shorter and easier to understand.
- Java: the language does little for me as far as reducing complexity, but great IDEs like IntelliJ at least allow rapid code browsing, "who calls this" queries, etc.
