How to create small, unique tokens in Ruby

That is is basically a "fork" of blog article i'm constantly returning to. It seems that the blog is down:

• Original article
• Internet Archives

My choice: Dave Bass’s rand().to_s() trick

Dave Bass proposed this which I picked up for my implementation (here for an 8-chars token):

For example, the list of options is "Foo", "Bar", and "Baz". At the bottom of the list (always at the bottom) the user sees "Add..." as a new option. When she selects that option, the <select> disappears, replaced in place with a focused <input type="text"> ready to accept a new option. It's important to note that this pattern is only usable in cases where the input is stored as a string, and you want to enforce a limited but extensible vocabulary of options. A possible example of this is colors, where you don't want to just let people enter anything, otherwise you would end up with "Gray" and "Grey" and possibly "grey".
