I just want you to know how hard I'm going to steal this and pretend I invented it when people think its clever.

- mensetmanusman 3y agoWe would joke in physics class that you either need to memorize the right-hand rule; or if you were right handed while doing the test, the negative left-hand rule. (because students would often make the mistake while holding their pencil during the exam of how to calculate the curl)
- ryandrake 3y agoI'm doing the same thing. I didn't[1] invent it either. 1: https://twitter.com/id_aa_carmack/status/419313776463077377 https://twitter.com/id_aa_carmack/status/419313776463077377
- ReptileMan 3y agoIt was common saying 30 years ago when we were preparing for IT Olympiads in Eastern Europe - if you do even number of errors chances are your program will work ok.
- littlestymaar 3y agoCarmack didn't invent it either, my physics teacher was saying that a lot 17 years ago so it's clearly a common thing.
- gattilorenz 3y agoa possible source is in the replies to that tweet: https://twitter.com/RobbieBC/status/419324772754132992 https://twitter.com/RobbieBC/status/419324772754132992
- littlestymaar 3y agoHonestly it wouldn't surprise me if it had been invented multiple times independently, it's just too obvious to anyone that has had to deal with calculation. (But thanks for sharing what us without a Twitter account cannot see otherwise anymore…)
- taneq 3y agoClearly we must now start referring to it as ‘Carmack’s sign error joke’ ;)
