"not helpful" @LucasWerkmeister
All my opinions are that of my employer but they don't know it yet & I am not telling you were I work. Apropos: If you need some idiot to kick computers for purposes of making them secure hmu, this job fucking sucks (vulnerability management, automation/engineering for your soc/isrt, ...).
PFP by a lizard that I am pretty sure transitioned at some point but I kinda lost contact with around the same time so I might only know their deadname & at this point it's too awkward to seek them out & ask. So instead I am going to credit them by their last discord handle I am aware of: fuck, md
