I mean, they added "bash scripts you find online", which are only a problem if you don't look them over or cannot understand them first... Their post is very much cemented in the paranoid camp of security.
Not that they're wrong. That's the big thing about security once you go deep enough: the computer has to work for someone, and being able to execute much at all opens up some avenues of abuse. Like securing a web based service. It has to work for someone, so of course everything is still vulnerable at some point. Usually when private keys or passwords are compromised if they're doing things remotely correctly, but they're still technically vulnerable at some point.
Most people aren't frivilously spending most of their money on things... Except maybe the rich, but most people don't have that much disposable income now do they?
Because most devs are just codemonkeys implementing what they're told to. This is pure manipulative propaganda from the suits who are already robbing wages from good devs.
Not "gravity a star has," but the motion of stars around/near galaxies. It is the general motion of groups of massive objects that hints that there is a lot more mass 'around' most (not all) galaxies than what matter we observe could possibly account for.
The 'not all' part is critical, because it points to something actually being there as opposed to the theory of gravity or relativity breaking down at larger scales.
Yea, that's why I added the, "not that they're wrong..." part. Interesting how no one actually understands what those simple words mean.
