Awesome blogpost by Chris Kiehl: Software development topics I’ve changed my mind on after 6 years in the industry. Excellent thoughts, and I agree with almost everything. A couple of thoughts from me below.

Java isn’t that terrible of a language.

True, but it isn’t that great either.

Functional programming is another tool, not a panacea.

True, but it’s far better than AOP/Interceptors/Annotationmania/Spring bullshit usually employed by Java practitioners instead. See my thoughts in the link above.

YAGNI, SOLID, DRY. In that order.

YAGNI: 100% agree.

SOLID: coined by Uncle Bob with whom I disagree on almost everything:

• The ‘L’ in Liskov substitution principle is useless since you shouldn’t use inheritance anyway; see OOP Inheritance
• the ‘I’ in interface segregation principle is refuted in Fallacy of future-proof;
• the ‘D’ - I don’t agree since crazy abstraction will affect maintainability.

DRY: sure, but not zealously.

90% – maybe 93% – of project managers, could probably disappear tomorrow to either no effect or a net gain in efficiency.

Haha, music to my ears :-D Just make sure you have a team of A+ players, then you can drop almost all managers.
