Is there a way to remove having to enter my password for everything?

Wake computer from Screensaver? Password.
Install something? Password.
Updates (biggest one. Updates should in my opinion just work without, because being up to date is important for security reasons)? Password.

I understand sudo needs a password,but all the other stuff I just want off. The frequency is rediculous. I don't ever leave my house with my computer, and I don't want to enter a password for my wife everytime she wants to use it.

How do you get the flavor out of it?

How do symlinks work from the point of view of software?

Imagine I have a file in my downloads folder called movie.mp4, and I have a symlink to it in my home folder.

Whenever I open the symlink, does the software (player) understand «oh this file seems like a symlink, I should go and open the original file», or it's a filesystem level stuff and software (player) basically has no idea if a file I'm opening is a symlink or the original movie.mp4?

Can I use sync software (like Dropbox, Gdrive or whatever) to sync symlinks? Can I use sync software to sync actual files, but only have symlinks in my sync folder?

Is there a rule of thumb to predict how software behaves when dealing with symlinks?

I just don't grok symbolic links.

Any word on the next generation of matrix math acceleration hardware? Is anything currently getting integrated into the kernel? Where are the gource branches looking interesting for hardware pulls and merges?
