In several things that I do, I require some form of randomness (for example, secure primary keys for databases, with almost no chance of collision error). To do this, I use your site to create them. A simple generation of numbers between 0 and 35, and then change them into their base-36 equivalent, however long the sequence needs to be, and you have an virtually unguessable primary key sequence. You can’t guess what the next key in the sequence will be. Very useful for keeping people from being able to hack your customer list and finding out who does business with you (they might be able to guess one, but the next won’t be sequential, so they would have to start all over again to find the next). I also use it in my writing, to generate datasets for locations and people by assigning integers to various items and using the site to pick the ones that apply.

Dr. Haahr,

I used a list of your new random numbers in your new set generator for the dog races on Friday March 14, 2008. Using your sets on the last 4 of 13 races generated 2 trifectas. The sets I use are chosen by calculating over and over until the sets generated line up with the previous winning numbers. In this particular case I used races 1 through 9 and matched them with the sets generated. Of course there is not a 100% match for all numbers. However, the way the races are set up, the 1st three finishing positions are the ones to key on.
