Functional programming

Good because unnecessary state is the source of much evil.

Even if we cannot do everything in functional, we should at least strive to clearly extract functional substes in what we do.

Ciro Santilli thinks imperative programming is just a superset of functional programming where you can have state.

C and C++: OK, you're old before the Internet and compiled, forgiven.

Python: OMG, please, just make it work!!! Your are interpreted!!! You are a hot web technology!!! Node.js and Ruby are doing just fine, and Ruby is not newer than you!!! See also: pip.
