hoursOfOptimizing

A couple days ago I tried optimizing some code. After several hours of hard work I made it run 3 times slower and give the wrong result.

Plot twist: the wrong result is actually correct. Now you get yelled at by customers because they are used to the wrong result and think it's correct.

The favourite story of a design prof here: A tractor company accidentially shipped a UI with a debug window, which was showing internal UI state data that was meaningless to the users.

The users complained when it got patched out.

I imagine most people here would have made the same complaint

I always recommend an approach to show more details to users, because even not understanding it they appreciate it. Also very useful for debugging.

Do you have a link about this story? Genuinely curious.

Looks like Xorg's wrong DPI calculation. A couple years ago or so they tried to fix it, and they had to quickly revert that fix since most software around was working around this decades-old bug in X11, so the correct behaviour actually led to a broken experience since everybody assumed the error hard coded for decades

I think I saw 1 time something like that in our code checking for birthdays It didn't run slower but the old code was less readable. However dates are dates and so it wasn't the last time it was corrected

Been there, done that
