Good Debugging Skills are underrated.
Best debuggers are good problem solvers.

Unless you meet that one issue that stays with you for hours

Do you mean skills using a debugger tool? Or skills used for debugging?

@irene i think op means being able to realise symptoms, hypothesise potential causes, eliminate and zero in on the root cause, and efficiently find the line of code that's incorrect/buggy. most likely using debugging tools.

id say using debugging tools is to confirm what one already thinks, rather than to trace or understand what's going on.

now that's a skill id also like to have.

@EpicofGilgamesh Hours? My record is at about two fucking weeks, but that was really A+++ level.

@bananaerror I always thought of those as deductive reasoning skills. You use them for solving basically anything with hidden information not just programming.

@irene yeah but you'd be surprised how many people are absent-minded and not very observant.
