The flooding a network thing really isn’t an issue, they’ll only flood for the first packet just to find the way and then it stops. Fire up Wireshark on a different machine and transfer a file between two other machines, you won’t see anything. I don’t know too much about WiFi but it probably does the same, it’s just a bridge to the same network.

Wired is probably better because machines can estimate your location from the SSID and they can leak the password giving access to the network.

Switches will flood a network when they don’t know the location of a MAC address but this should only happen for the very first packet which is more likely to be DHCP or some boring background thing like that. As soon as the correct devices get the packet and replies then each switch along the way will update its MAC address table and they’ll know exactly which port to use until it expires (which depends on the switch, I don’t have a ballpark idea).

I just browse All the subscribe to communities I see and like. One thing you’ll find on Lemmy is that a lot of the communities are just Lemmy equivalents of Reddit subs, so if there’s one you like you can just search the name of what you like. It’s usually a case of find the version of the sub you want that’s the most popular. Because this is Lemmy and there’ll be different instances of the big subs, like if you want funny you might find funny@piefed.social or funny@lemmy.world, and more. There’s usually one instance which is the one to use. I understand they’re in the process of fixing this by having it so that they all sort of subscribe to each other and you can just follow one to follow them all. Unfortunately doing this involves using the search which I also find pretty terrible but I understand it’s also a priority issue they’re fixing right now.

I’m no Windows fanboy but I have to use it quite a lot, at home and at work. I don’t know what versions or settings you guys have set up but I’ve never had a Windows update I can’t postpone, ever.

I use it at home just because I wanted to try something different on my laptop, I really don’t understand what some people love about it so much. It’s bot terrible or anything, I just find it a bit clunky and there’s nothing remarkably good.
