Oh boy . Can ' t waits <| sep |> are still open , kinda . the staging boards that is . it ' s kind of a free for all . The place is garbage and really just a few members left tearing eachother apart . <| sep |> It ' s also worth noting that the online service costs more now on PlayStation than Xbox live . I think it used to be 20 $ for 3 months and they raised it to 30 $ 25 $ for xbox live . Not sure why they didn ' t just make it the same price . About games with gold though , I wouldn ' t exactly consider it a feature that swings you either way . The games featured are usually mediocre at best . I don ' t know how it is on PS 4 but I doubt they ' re giving away anything worth much money either . <| sep |> The mod function % in programming languages is supposed to be welldefined i . e . has a unique value for every input , which poses a problem from the point of view of equivalence relations . Both of the following are true 1 1 mod n and 1 n 1 mod n . However , to have a welldefined function i % n , you will need to pick one value out of the equivalence class , and whether you pick 1 or n 1 is essentially arbitrary . Personally , I think that picking 1 is a little unintuitive , since now we have 1 % 2 ! 1 even though 1 is odd , but maybe there are other places where it would be convenient to pick 1 .
