When I was getting my pilot's license, multiple times I started up without unchaining the tail. I joked about it with another instructor, and he basically said that it had literally never happened to him and that I should be doing a final walk around. I'd done even more embarrassing things, sitting at the runway ready to go and the tower tells me my baggage door is open. Since making that final walk around a habit, n…

I was hoping someone would mention being a pilot in this discussion. If you learn to fly, you will learn to follow checklists. Many, many checklists. A good instructor will tell you that while you do need to follow the checklists, it never hurts to do one last check. One final walk-around before getting in the cockpit, one last check of radios/transponder, one final scan across your engine instruments before takeoff,…

I am notoriously absentminded. I would constantly forget my lunch, leave the lights on, whatever. Since writing down checklists for my morning and evening routines, I don’t miss anything. The fact is that we’re human beings. As the book “Getting Things Done” says, your mind is for having ideas, not for holding them.

This may not be what you want to hear. Making mistakes properly is progress. Make the exact same mistake multiple times? You might need to write them down as you find them. At one startup we had a motto: Measure once, cut twice. Being fix the bug, then write code to mitigate that risk in the future. Fix it twice. Now in critical systems like traffic lights and the like, mistakes kill people, so you test the everlovin…

In critical systems like traffic light and elevators the key is to have a simple system so you don't need to test the crap out of it. Using something like a finite state machine.

Part of making fewer mistakes is going for simplicity over complexity.

How to make fewer mistakes.

Yes, but how did you do that?

Text surrounded by asterisks is italicized, if the character after the first asterisk isn't whitespace.

Text after a blank line that is indented by two or more spaces is reproduced verbatim. (This is intended for code.)
