Don't write stupid comments on code, but write comments.
I should add "do not write in comment what you could have write in code".
That include the name of function/variables, the types (if it's a typed language that is), the exception that can occur, any optional result, constant arguments.. etc...
Couldn't agree more. Comments should describe the "Why" and not the "How". The "How" is already present in code.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
