“Good debugger worth weight in shiny rocks, in fact also more”

I’ve spent time at small startups and on “elite” big tech teams, and I’m usually the only one on my team using a debugger. Almost everyone in the real world (at least in web tech) seems to do print statement debugging. I have tried and failed to get others interested in using my workflow.

I generally agree that it’s the best way to start understanding a system. Breaking on an interesting line of code during a test run and studying the call stack that got me there is infinitely easier than trying to run the code forwards in my head.

Young grugs: learning this skill is a minor superpower. Take the time to get it working on your codebase, if you can.

I used to use debugger when I was young - disk space was small, disks were slow and logging was expensive.

Now, some 35 years later, I greatly prefer logs. This way I can compare execution paths of different use cases, I can compare outcomes of my changes, etc. I am not confined to a single point of time with tricky manual control as with debugger, I can see them all.

To old grugs: learning to execute and rewind code in your head is a major superpower. And it works on any codebase.
