    @3:55 this doesnt make sense, g^a isnt public, g^a mod n is public. for instance, bob would be doing this: g^(g^a mod n)^b mod n?

    An idea: 1. The robot does not get a reward if the button is pushed. 2. There is not one button but billions available for every human to push. 3. If an attempt is being made to stop someone from pushing one of the buttons. Someone else will inevitably push one. Therefore it is not possible for the robot to stop any of the buttons from being pushed. The effort for trying to stop all the buttons from being pushed is so high that delivering the tea is a much better option.

    And that's why the halting problem should be explained with pseudo code instead of an actual programming language like python: otherwise people will start arguing that the compiler should thorw an error, that the libraries could be better, that the memory is finite etc.. etc..

    Your videos helped me to pick up R. Before this I did transformations of excels provided to me in Power BI (newbie data analyst here). Well it works, but.. It's not pretty. And sometimes painfully slow. While going through these series, I learned how powerful R is, and the concepts You tell about - I didn't even know about anything of that. These series are invaluable for those, who pick up data analysis with no background education - just learning on their own. Now I implement R scrips in my own solutions and clients are happy :) Thank You for the outstanding work. Very, very highly appreciated.

    Human and harm could be defined using machine learning algorithms. Show pictures or data that we intuitively know is or isn’t a human/harm, and teach it. We might need tens of billions of examples? So be it. If it goes horribly wrong? Have a killswitch to just end the functions of the robots, or test it on human like dummies.

  • Кирилл Рагузин

    The thing to remember is that the trick relies on the assumption that high level code designed for one machine can be directly compiled on another one. Generally it is not the case because of different incompatiable environments and hardware features available on different platforms. So in practice porting tends to get a bit more complex and messy than described here.

    Instead of having a point limit, let it aim for a Highscore. Every successful task earns points, every appropriately applied safety function earns points, every installed safety feature and safety awareness line of code earns points. Every safety awareness line of code missing earns minus points, every failed task earns minus points, every failing to appropriately implement safety functions where needed earns minus points, every inappropriate implementation of safety functions earns minus points, every pretending to obey safety features earns minus points, etc....

    Fantastic video! two thoughts: 1) Regarding the suggestive claim that there may be a connection between the Y operator (key in recursion) and the double-helix structure of DNA (key for self-replication)... While it is true that both sides of the helix in DNA encode for the same information, they do it in complementary form (ACGT would pair with TGCA), thus each DNA strand is a complement of each other and not the same element duplicated. While I love the idea of this potential connection between genetics and computer science, it would be awesome to see a way to satisfy such "complementarity" while also satisfying the expression, which does not seem fully compatible with this biological observation, unless we treat each xf(xx) as an "information packet" rather than an actual string or physical sequence-based molecule. 2) Do you know if the company Y combinator actually has that name due to a "recursive" culture in building and supporting startups?

    Couldn't the compiler be simpler if the editor checked and signed the code? If the editor is trustworthy, the compiler wouldn't need to check the syntax. The editor could even be much more restrictive than a standard compiler for this language. If the editor could do the type checking, it should do it.

    • nosuchthing8

      @Günter Hofer I admit to being a user of compilers. I don't know enough to comment on your proposal.

    • Günter Hofer
      Günter Hofer Day ago

      @nosuchthing8 Every piece of code should be checked, and signed if it passes the test, and only signed pieces of code should be compiled. If the programm should read keyboard inputs, they should be checked before the program sees the correct inputs. Every input should be checked before the programm sees it and accepts the signed inputs.
