    Look at the inverse of the square root function, f(x)=x² (https://www.desmos.com/calculator/2v5gzbhru8)

    You can get the sqrt of a given y by looking at the x axis. E.g. the value of y=4 has two solutions, x=2 and x=-2. This however does not mean that the sqrt of -4 is also 2! If you look at graph you can see that there are no solutions for y less than 0.

    sqrt(-1) , sqrt(-2) (i ill omit imaginary numbers here) and so on do not have a solution. There is nothing you can replace with such that x × x is < 0 because multiplying two negatives always nets a positive.











  • I was shortly in a project where the team and the customer meant the fucking Oracle DB when they were talking about “the backend”.

    There was Java Spring Boot (on some outdated, old old version), but all it did was pass args from a “REST” API (doing essentially RPCs with POSTs is REST, right?) to the DB.

    The DB then had functions upon functions written in pl/sql that did the actual work.

    I have no idea who the fuck thought that that was even remotely a good idea.

    Anyways - I am happy to have moved on to better, more sensible projects :D
