sudoedit runs the editor as the original non-privileged user, which is nice if you're using a configurable text editor like vim/emacs so you're not suddenly using whatever (lack of) configuration the root user has setup. It c

I can see why Google would not require G Suite customers to set up DKIM, but why do they not have it set up for google.com? It seems like it would have added another barrier of defense in the case of this bug.

I am pretty sure you can end up in the sort of situation where ordering 3000 costs less than ordering 2500 on Digikey, and in my experience the same goes for other major component distributors like Mouser. It seems to me like it kind of pro
