How do I remove the Devise route to sign up?
...d to do this as well, but a thread on the devise google group dissuaded me from searching for a really clean solution.

Why is it impossible to override a getter-only property and add a setter? [closed]
... property doesn't necessarily translate into read-only. I interpret it as "From this interface/abtract you can get this value", that doesn't mean that some implementation of that interface/abstract class wont need the user/program to set this value explicitly.

Java Replacing multiple different substring in a string at once (or in the most efficient way)

Test if characters are in a string
...prints to its output string.
Now, the grep program is basically a filter, from lines of input, to lines of output. And it seems that R's grep function similarly will take an array of inputs. For reasons that are utterly unknown to me (I only started playing with R about an hour ago), it returns a v...
