    Linux apps follow simplicity principles. If you don’t have permission to delete a file, why assume you may know the password of the user who has permission?

    You can preface sudo to any command to execute it with root privileges, which would be similar to running as admin in windows.

    Graphical apps do tend to ask for authentication if it makes sense. No userland apps should need more permissions than the current user’s in order to run.


  • Spain used to have a budget of around 1% of their GDP for the military. It was so much that they actually could not spend it. Now that the budget has tripled almost overnight, they are having an internal crisis because there is no way they can use up all that money, even if they overbought 200% of supplies and overpaid for them.

    Increasing military budget is useless, because the service will not improve with it, just the useless spending and inefficiency. And because of the rushed spending, I’m sure the move will increase corruption.



  • Sound cannons are actually pretty weird, in that they don’t work like you’d imagine them to work. They produce sound when multiple beams of ultrasound collide with an object, so if they’re pointed at you, you’re the one producing the sound that hurts you. That’s why they’re so effective.

    Some people online have done some tests, and thin cardboard appears to be the best way to stop them. Put the thin cardboard before you, and it stops most of the sound. It can be the cardboard from a poster, if you have one.

    Ear protection headphones (for workshops) also help, and their effectiveness is enhanced further by wearing small earplugs inside. Active noise cancelling headphones don’t help and can even be counter productive, so don’t use those.
