On the days I go into the office:
Tennis shoes, Jeans, Button down short sleeve shirt, or Polo shirt.
Work from home days:
Same thing except I wear a t-shirt.
If you are going to dual boot and your computer has room for 2 drives. The way I would recommend doing it is to add a second drive for Linux, and disconnect to windows drive from the computer. Do a normal linux install. And then add the windows drive back in. Then you can set one of the drives as the default boot device and if you want to boot to the other just open the Boot options on boot.
This keeps things totally separated and you can even remove one of the drives later if you want to single boot.
I had a dumb tv that I was using with a Roku streaming box. The TV became no longer supported because of the HDMI version that shipped with the TV. Roku stopped supporting certain versions of hdmi to prevent piracy.
Even if you have a “Dumb” device, newer tech may just say no.
