reboot -f

Because real men login as root and don’t care about such silly things like an init system or file system syncing!

To quote the man page:

-f Does not invoke shutdown(8) and instead performs the actual action you would expect from the name.

I can’t speak for all European countries, but at least in the Netherlands they’re not a thing. We might still have money orders, which are similar, but I’ve never seen one used.

Instead we can just make instant bank transfers, even using a QR code, which you can generate in your own banking app and can be used with any other bank.

Same here, I used to have this image in my head of a eccentric entrepreneur pushing technology to the max with ‘fuck you money’.

Sure he said some crazy shit sometimes, but it kind of felt like he didn’t have much of a filter.

Around the time of the Thai cave thing this started to change, but I still gave him the benefit of the doubt until that point.

After that, things just went down hill…

Security through obscurity would be having a system connected to a network, but relying on a secret / unknown protocol to secure it.

Air-gapping a system is a real and very useful security method. That being said, it’s not enough by itself.

If you’re interested, have a look at past examples, like the recent work on breaking Tetra communication standard and Stuxnet.
