Another Wacky way to Authenticate Users

Instead of a password, analyze how they type. This is about as cool, and as scary as the programs that can figure out your passwords by listening to the clicks on the board...

Fonts

I love fonts, and this site seems to have a lot of them. Yeah, it's dorky, but what do you expect when my handwriting is so bad.

More ruby fun

Interleaving arrays together to form a super array. Kind of in reverse of what I need, but the yield comments made me thing about the idea that I could do something like


class Array
def couple()
(length-1).times { |n| yield(at(n), at(n+1)) }
end
end


Which *seems* to work, albeit throwing complaints all the way. And it does the a,b;b,c;c,d sort of thing with a list...

Working in Ruby

So I'm working in ruby and I'd like to get the following from one list:

lines = %w{a b c d e f}


irb(main):211:0> colors = lines.clone
=> ["a", "b", "c", "d", "e", "f"]
irb(main):212:0> (1..colors.length/2).map {|z| [ colors.shift ] + [ colors.shift ] }
=> [["a", "b"], ["c", "d"], ["e", "f"]]


so either [a,b], [c,d],[e,f] as a list (which I l hate how the above destroys colors inside the loop
or
a,b ; b,c ; c,d ; d,e ; e,f as a list.

I did use the following for the second part:


colors[0..-2].zip(colors[1..-1])


Any hints,tips suggestions would be appreciated.
