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.

Dear Sir,

Came across your web site some time ago when I was dithering over what CDs to put in my 12-CD cassette in my car. In those days I had in excess of 500 CDs, and could never make up my mind which ones to listen to. I was tending to put just my favourites in week after week. I googled ‘Random Number,’ and your site was the result. I have now well over 700 CDs and religously put in the CDs that the number generator commands.

Thanks for the service.
