Networks
I have multiple computers in my house, a couple desktops and a couple laptops which I use normally. I also have a file server, and a couple other servers for various things. I have a couple IP cameras which are isolated from the rest of the network, but don't really have any “Internet of Things” things. In other words, no network-enabled light bulbs. I do have some things controlled by X10 controllers connected to one computer, but no commercial embedded IoT.
Having a file server, as well as an LDAP directory to sync UIDs and GIDs, I have the makings of an infrastructure you might use in some sort of organization, not for one person. This is convenient when it comes to things like NFS or making backups, but there is a degree of overkill here.
It is kind of a hobby that happens to be useful. Things get frustrating as they often do with computers, but I don't mind being in control. Granted, a big part of maintaining sanity has been getting things to work simply and reliably, so that most of the time I'm not trying to fix things. Sometimes it's inevitable, of course.
