You have several typos in the Joosy website (unless it's part of a joke I'm unaware of, as they repeat the same incorrect \n correct pattern).

    ack -l "Deterimes" | xargs perl -pi -E "s/Deterimes/Determines/g"

in your root if you don't want to search for them manually.

Note: requires ack installed (like grep, but typically much faster and nicer to use, for me at least).
