This gettier concept is new to me, but what's certainly not new is trying to wrap my head around errors in the code. I'm a relatively new developer and I've many times asked more seasoned coworkers about what they do with all the their thinking they perform and possibly code they write during a long error invalidation process. Say you try fixes b,c,d,e,...,z (some of which might be objective improvements, now more robust code) then you finally fix the bug by trying solution A. What do you now do with the code for attempts b through y, and more unclear, all the thoughts in your mind that went into those efforts? Just forehead slap and move on?
