    I’ll coincide with you in that first-aid-quick-repairs is something people should in the best of cases know how to do, but setting a envirental variable or installing a package is not a “simple thing”. I’ve worked with engineers that programmed math models for a living that had no idea what a enviromental varible even was. Yes is easy to do, but the concept behind it, what it is, what it does and why are not simple, without the right background or the will to learn about the topic.

    And, about user and owner. Sure, I get your point and personally I share it. But again, that is an opinion, tell a non-interested-user that they don’t really own their rig until they know how to use the terminal and I assure you that most of them will disagree.

    Do you know how everything in your house works? How to repair everything? No right?

    Would you be brave enough to mess with the grounding of your house, or the AC or the heaters, the washing machine, the doors? Not eveyone wants mess with every (subsystem) thing in their house/live"

    Most of the people I know want their PC to work and if somwthing goes wrong they just send it to repair or ask somebody else to fix it, they don’t wanna do it themselves, which I find normal, they have little to no interesting in PCs, and that is compleatly fine.

    And before someone says "Yeah, but the computer won’t kill you if you fuck up the fixing or messing, let me tell you, a “sudo rm -r” or “sudo chown -R” can fuck you system BAR, making you loose important data and info.

    -…But refugee -I hear you about to type-, they SHOULD have 10921 back-ups in atleast 2542 independent locations. Yo, they don’t wanna even see the terminal, and you want them to interest themselves for data integrity and redundacy? Come on.

    1. Decide on a random N and what tails (even) and heads (uneven) mean.

    2. Each party generates a random number

    3. Combine the numbers with a conmutative operation of some sort, the harder the operation the better.

    4. Take the hash N times. (Can be done independently by each participant)

    (4.5) optional: for extra robustness, do some hard-to-calculate transformations to the result of 4. (Can be done independently by each party)

    1. The final result is either uneven or even === coin toss. (0 will be treathed as even*.*)

    This is not infalibe, one party could get all the numbers a precalculate a answer to get a specific result but they will need to randomly try numbers. adding some timing constrains, using big numbers and hard operations would make that sort of attack not really practicable.

    Nice question, had fun thinking about it!
