There are also people with 10+ years of using static typing languages like Java or C++, that then go to Python or Lisp or Racket and find out they are more productive with dynamic typing, while writing even more readable code than before.

Every time i hear some person complain about dynamic typing as if it was a world filled with pitfalls and dangers, I think in Common Lisp and how great is its dynamic type system. Good example.

When static typing vs dynamic typing is discussed, i see that often a mistake is made and "static typing" is confused with "strong" typing, and "dynamic typing" is confused with "weak typing". Just FY

Best article on FP i've ever read, this deserves a bookmark. Although to me it's not only about FP but also about data-centric development.

No, it is not, please do take a deep look at oversampling in D/A conversion and the artifacts of digital filtering, articles are out there.

Good points in the article, but it has some flaws. The problem whenever somebody writes about digital audio, is that it is very tempting to hold on to sampling theory (Nyquist limit, etc) and totally discard the problems of implementing
