I keep a small sized notebook with the first page or so an index of sort, and then a page for each service or server. Doesn’t have to be a lot, but be sure to give your future self all the info that will be needed. For instance not just a password, but also the username. Any problems you have had and how you resolved it. Depending on the sophistication of your network, vlans, firewall info, is it wired to your router or switch, what port. What slot of your multi button power bar it is plugged into, so if you need to cut power or restart you dont have e to randomly push switch accidently turning something else off. Basic server specs, what type/size of raid or HDs, do you have room for more HDs later, RAM slots and what’s in them currently.

I might get some flack from writing down passwords, but a password manager can remedy that. I still keep some of mine on paper tbh, I have had pw managers break or go offline and I am not terribly worried about normal theifs knowing how to ssh into my linux boxes.

Documentation, take notes on what you setup, ports opened, accounts created. This will be very valuable when you envitally get services setup and forget about them.

Any idea of what they are looking into? I always thought neutron detectors were for detection of nuclear activity.

I dont want to be too specific, there is a reason, I work with radio infrastructure quite a bit. A lot of these systems hide behind obscurity alone. Not great against national actors that may want to do harm.

Thought cars were bad, not sure many people have an understanding of how our emergency broadcasts and alerts work. US needs some huge infrastructure updates.

I have always had a conspiracy theory that the ink management requirements are set by national security input. All printers have a yellow dot pattern added to every print to identify the printer by a forensics team. I wonder if this is why the ink landscape is so shifty. They want to make sure those dots get printed. My thought on why you can’t print black and white when you are only missing colored ink.
