You would still need to be able to displace suspended particles, bacteria, and small insects, otherwise you wouldn't be able to teleport outside of a clean room

You could pass through anything as long as you're willing to destroy it in the process

If you work in demolition you could take out a wall by continuously teleporting through it, if you wanted to do typical superhero stuff it would be good in a fight but nonlethal attacks aren't really an option

Being able to teleport into a region already containing air without creating a nuclear blast requires that you can already either instantly displace the air in the target region (which would make a Very Loud Noise) or switch places with it, so there are possible interpretations of the power where teleporting into a fence would leave behind a detached section of fence or bend it out of your way

It could, so while you're using it you should make sure you don't have anything sensitive onscreen.

If your desktop supports Wayland at all, you could switch to it while using Zoom, even if other things don't work as well, then switch back when you aren't.

I don't think that's a feature exclusive to blockchain, though? I could imagine portable identity being implemented pretty easily with normal signatures. A user could hold a private key, and they could prove their identity to any server by proving control over it, no need for gigabytes of state history on disk.

So they'll give my scores to Mark without even asking but if I want them to send them to my college I have to pay?

You need to use root or pass through some other access control mechanism to control network interfaces or audio devices on Linux too, Android's access control mechanism for those things just isn't built with shell scripting in mind because using a terminal on a phone is a pain...

Rooting barely affects security at all if you're using your brain. Don't give a suspicious program root access, same as you would on a normal computer, and you'll be perfectly fine.

If your phone is running a custom rom, most of them disable the carrier check before enabling hotspot, and you can pass tethered traffic through a free vpn to hide it from any ISP-level tethering detection

Some games use a "trust" system based on human reviews of your gameplay that affects how you are matched with other players, but there isn't a respectful way to force people to use just one account so that the trust score can follow the person. The best way I can think is to tie the purchase of the game to that account, which many services do, but that breaks the used games market...

Good to know

I think if they were categories instead of reverse domain names, it would at least be easier to remember. As it is now they're mostly just meaningless, and I think it would be better if you could refer to apps with only the last part as long as it wouldn't create a name collision.
