But it introduces an artificial difference between edges and corners. You'd get the same ability for corners if you did them after the edges.
The slightly counterintuitive “magic” is that you can trade a corner swap for an edge swap: for permutation parity, corners and edges are interchangeable.
I'm fine with permissions. Heck, it's what I already say.
Login, no, just no.
Login is ambiguous to begin with, is it the action or the user identifier?
Login as the process of logging in, the best interpretation, is still pretty limited: authentication is the validation of a much longer chain of events than that. It may start with login, but it lasts for as long as the service accepts to believe such principal is behind such actions.
Login as username is IMHO the most common use of the word, and most obviously the wrong one to mean authentication.
To make things me interesting, auth already means authentication to me. I accept it can lead to confusion and a better substitute would be welcome.
DoTT copy protection involved balancing the portable battery's chemicals. Copying a word or phrase feels off brand for a LucasArts game, that was more of a Sierra thing.
Which specific version do you distinctly remember?
You're right, I do remember the battery challenge now. I was possibly confusing a similar tactic from a Sierra game (which I also played my fair share of). Bear in mind, this was over thirty years ago - it's amazing how our memories can take on new shapes over time.
