Ask HN: How to Double Your Salary?

Hi HN folks,

Forgive me, but you won't find any answer to this "irrelevant" question in this linked paper, http://lambdaway.free.fr/lambdawalks/?view=iife, just an attempt to present in a few words the basics of coding, as they appear to me today, after having wandered among more familiar languages but full of grey areas. I'm looking for your opinion, kind if possible, so that I don't continue my quest alone.

Thank you in advance - alain marty
