The trick is that you loose access to every file on the system. chmod is also a file. And ls. And sudo. You see where it’s going. System will kinda work after this command, but rebooting (which by a coincidence is a common action for “fixing” things) will reveal that system is dead.

sudo chmod 000 -R / is very fun way of braking your system and is not widely known 🙂

I have two cats that are both crazy for their own reasons.
One is just in love with marshmallows. He will not eat them that much, but loves to bite and kick them. I think, he just loves the texture of that. He also love to lick every sweet there is. We have to keep him away from glasses with fountain drinks, because he will lick edges.
Second one just loves plastic. When he is hungry, he will not look for food, but for plastic to chew instead. Any plastic bag, ribbon, anything, he will munch that until he will choke… Twice I had to pull a present ribbon from his throat… It’s especially hard on Christmas 😃

Clarification regarding carrying weapon on sport license in Poland. You are allowed to transport it loaded, but the regulation says you should not expose it, not to bring attention to it. Currently sport license is the most common license in Poland because it is the simplest to make of them all (not meaning it’s easy per se).
