well it depends, I mostly try to create my code so that things can run in parallel. I also barley use a debugger, even for code that does not run in parallel,

well it depends, I mostly try to create my code so that things can run in parallel. I also barley use a debugger, even for code that does not run in parallel, mostly because I'm used to make logging calls at the right places so that I can find issues way faster than with a debugger (most often I'm only run into hard issues or issues where a debugger will fail, i.e. build scripts -_-)
