Less formal alternative: IMHO: You're wrong.

No. Conservation of mass and energy only prohibit the total mount of mass and energy changing. The universe could have always existed with that mass and energy. We have good evidence that a lot of mass and energy was spread out by the expansion of a much smaller universe around 13.8 billion years ago, but we don't know what the universe was like before that, it could have always existed, or it could have been formed by the collapse of another universe, we don't know for sure.

Anyway, the laws of physics are just empirical observations, they have been proven wrong before. Einstein's general relativity disagrees with Newton's laws of motion and, further study reveled that Newton was (very subtly under normal conditions) wrong.

So many sites just outsource to content farms and have flooded the internet with SEO crap for years. With automation making this easier and cheaper it will probably only get worse.

Right now, generally well know sites like Wikipedia are fine, random people's blogs are fine, but the first google result from some random company is almost guaranteed to be shit.

Your going to have to read the input one piece at a time, allocating a bigger buffer as you go. (realloc is the way to go here) I recommend putting the input reading code in a function do you can easily use it multiple times.

If you don't bother to provide any argument, I won't bother to argue.

Some of my favorites are from programming: " How to forcibly kill ophaned child" and "kill all children of parent".

You can connect to most instances over Tor, but hosting a server over a Tor hidden service would cause problems as it can't be connected to by stock servers. (If you convince others to run other Tor hidden service instances, they could probably federate with each other)

How do you tell if someone is an Arch user? You don't, they will tell you.

Most are on lemmynsfw.com. You can subscribe so that they show up on your feed even if using another instance. You will need to have "Show nsfw" enabled in account settings.

The simple solution here is to try to contact someone before assuming they have been kidnapped. Of course the goal of scammers is to make you panic, and stop thinking rationally. A deepfake could definitely help with that.

Foss pretty much exclusively, but how easily possible this is really depends on what you do.
