To rectify this abomination, it comes from two ways:

a = []
# this was the b:
characters = ("A".."Z").to_a + ("a".."z").to_a
characters << "-"

10.times { a << characters.sample }
a.join("")


or


characters = ("A".."Z").to_a + ("a".."z").to_a
characters << "-"

10.times.map { characters.sample }.join("")
