@b0rk The way Git displays octal file modes to the user is so unfortunate :( It gives you the false impression that files in a repo *could* have unusual permissions/types, or that perhaps the umask on a commiter's machine might affect the permissions of newly committed files, even though it […]

i could put both the service account and my personal one in the same groups for shared access of the specific files i need, then curate their permission bits, but that feels like busting out a bazooka to explode a mosquito-sized inconvenience. plus umask can be annoying on nixos i think maybe

wait what these exposure points are not added linearly. fixing `UMask` didn't improve my score at all. summing the right column i should have like 1.5 exposure but it says 1.1. what.
how is this calculated

wait no i'm just stupid i read the docs and `umask` actually means which bits are turned off. ??? . so you have to invert it

How much longer is this allowed? Umask, expose, and prosecute these people! Shame on our government!
So many videos of these masked thugs Making Us Safer
ICE agents in tactical gear chase down and tackle a U.S. citizen in L.A.
After realizing he’s American, they just slink away.
Their only explanation: “Why were you running?”
Probably because two masked men with guns were trying to snatch him.
