Being forced to use the shell to work with some exe file I didn't write.
Made up bundle identifiers that are not the developer's actual reverse domain name.
These are not something you just make up on a whim, they're to identify the developer and app!
I wish code signing would validate and enforce actual bundle identifiers…
When I first started using tech forums (or Bulletin Board Systems or whatever...) grammar mistakes really bothered me. As the years went by, I realized that very often the grammar mistakes were from people where English was not their native language. And they were getting the concept across in broken English much better than I could comprehend in some other language. So I've become much more tolerant than I was say 20 years ago.
Now I am more like this image:
This is Pet Peeves. It's literally a thread of over 4000 examples of our intolerance.
In the rest of the forum, I rarely see people being grammar Nazis and we do indeed have a lot of users who don't speak English as their first language, and do it very well.
But yeah, this is Pet Peeves :)
