On MacOS this will do it:

printf 'net.inet.ip.ttl=65\nnet.inet6.ip6.hlim=65\n' | sudo tee /etc/sysctl.conf

Can’t personally speak for other OSes at present. Here’s a SO post about Ubuntu: https://askubuntu.com/a/670276

You can also just increase your laptop’s initial TTL by one and then they can’t tell.

I’m a nerd. I know vaguely what RCS is because I had a discussion in 2019 with a friend about it. Do I have it? Do I use it? I have no idea. Is it an app or just a protocol that happens behind the scenes? I would assume the latter. My phone’s a few years old, isn’t everyone’s? Probably that means I don’t have it. No way to tell and I’m not going to bother trying to find out.

I’m so much more technical than most people btw

How can it not be true though? Terminal shines when you chain together more than one operation.

Imagine doing this in a GUI: list the files in a large directory, ignore the ones with underscores in them, find the biggest file, read the last 1000 lines from it and count the number of lines containing a particular string.

Thats a couple of pretty straightforward commands in a terminal, could take 30s for an experienced terminal user. Or the same task could take many minutes of manual effort stuffing round with multiple GUI applications.

I’m certain that I do tasks like that (ad hoc ones, not worth writing dedicated software for) tens of times in a typical work day. And I have no idea how GUI users can be even remotely productive.

“and so” is perfectly valid as a conjunction for implying causation. “Thus” would be a synonym. It fits better than “and also” which doesn’t imply causation and so isn’t the right word.

If those shelf brackets are fixed in place and screwed in with two screws above each other that’s probably enough diagonal bracing for lightweight use, considering it’ll normally be screwed into a wall too. The fact that theres no horizontal bracing at floor level might be a bigger issue — those feet will be easily bent/broken
