RandInt: For all your application random number needs...

Awesome. I've been a longtime random.org user but have always complained about the lack of a Comic Sans interface. It seems my prayers have finally been answered:

http://randint.com/labs/comicsans.php

(My first Comic Sans number was 17 - it even feels more random than the competition!)

Does anyone know how these are generated?

Could anyone explain what this paragraph means from their FAQ:

"Since 1992 at least 24 companies have set out to solve the random integer problem. Most fail for obvious reasons. It is rumored that a few of our competitors may have a 1-5 algo that works approximately 40% of the time. Our 1-100 algo is rock solid. In short, there is a consumer need for a random integer but the problem isn't easy. Even Google is rumored to be 2 years away from a reliable 1-50 algo."

I'm probably being stupid but I don't understand what 'works approximately 40% of the time' means in this respect.

Also this is cool : https://www.fourmilab.ch/hotbits/secure_generate.html

Cool, but I think your API is too complicated ;)

A command line version:

curl -silent randint.com | grep "</h1>" | sed 's/\<\/h1\>//'

I got 88 on my first try. That's not very random at all.

Seriously though, are these true random or pseudorandom? There's nothing to say how they're generated. I personally want a true quantum random number generator, so that I can use it to make decisions and be guaranteed that an alternate-universe counterpart of myself made the opposite decision. That way at least one of me is going to be right.

Cool. Would be even cooler if you could specify a range.

No JSONP?
