How to create small, unique tokens in Ruby

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:

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):

A combo box, in this setting, is a `<select>` that offers the ability to edit its contents, directly within the current form.

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".
