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.

Thank you for offering the random number generator. I have used it for a research on the effects of target specific communications in a N=2000 population of Dutch War Veterans. In the experimental setting it was necessary to randomise the research population and to divide them over four sub-groups, similar in size. The only acceptable way was to do so by adding a randomised variable in SPSS. Afterwards it was possible to assign the subjects to one of the groups by sorting on the randomized variable. Of course I gave due credit in the report by mentioning your service and revealing the URL.
