    🔒🧠 "Understanding" ECDSA: Because nothing screams 'security' like a tangled mess of modular arithmetic and a cameo from Fibonacci. Who knew deciphering digital signatures required a PhD in cryptic-ology? 😂🔍

    Terrible accident in Rome.
    2 police patrol cars engaged in different crime operations, both driving at full speed and with their sirens blaring, crashed at an intersection.

    Probably each driver just heard their own siren but not the other's.

    So, 2 overlapping concurrent alerts summed up to none.🤔

    (It seems there could be a more general law to explain above event, but I'm not very sure what it is)

    Lo and behold, now #OwlLisp (a dialect of #Scheme without anything mutable in it):

    CW: Rosetta Code

    I have added #ATS to the languages for which there is a solution to the #RosettaCode #ModularArithmetic task:

    Modular arithmetic - Rosetta Code rosettacode.org/wiki/Modular_a

    This task was practically tailor-made for #Ada. :) But ATS lets us easily extend the language to handle modular numbers.

    #ATSlang #FunctionalProgramming #Proofs

    Update: After reading the task language again, I added some more commentary, to point out what I see as a flaw in the task.
