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.

It's common knowledge that a background of white noise tends to obscure other noise from outside the house and bedroom that can interfere with sleep.

I had never tried it, but decided to give it a go with a few dozen audio files borrowed from your site. I filled up a 700 megabyte CD with white noise, tweaked it to emphasize the lower frequencies, and had it set to repeat. The results were much more satisfactory than the next best audio background I had: a recording of ocean surf. Thank you for giving me a better day's sleep! (I work at night.)
