I am using your random number generator to set the value of a proposed currency called the Wall Street Dollar. This currency would be intended for transactions among parties who seek exposure to conflicts of interest in the financial industry, such as proprietary trading, investment rating, executive compensation and financial industry political contribution.
Pseudo-random numbers were out of the question, since they would be vulnerable to the kind of manipulation the new currency was invented to avoid. Only the highest quality random numbers could be used.
They could also be used to introduce minute random delays into the transaction processing of the proposed exchange for Wall Street Dollars to ensure fairness and to thwart high-frequency trading.
Your service is indispensable.
I meant to email you a long time ago, but kept putting it off until the work was published. Anyway, I used Random.org data initially for my final year project in 2003/2004. It was research on sorting algorithms in the presence of caches and branch predictors. Back then the data was available for download in 10MB blocks, and there were 16 of them. So I uses all of them, 'cat'ed together, as the data to be sorted.
Having truly random data made me certain my results weren't due to my errors, and having so much of it made my sure it wasn't an anomaly. That was especially useful as a mere undergrad, when I wasn't really sure what I was doing.
Thanks a lot for Random.org, and for the data.

I write and use molecular dynamics and Monte Carlo simulators which have their own pseudo-random number generators (for portability and reproducibility). These require the user to input a random number seed. If I want to perform an ensemble of N statistically independent runs (e.g., with different initial conditions), I need N independent seeds. So I use your site to generate seeds to paste into my input script, i.e., your random generator generates random seeds for input to a pseudo-random generator. Say that 5 times fast.

I am a pilot studying for my instrument rating (complicated procedures used for flying in clouds and low visibility) and I use your random number generator to generate simulated Air Traffic Control clearances. I substitute the numbers in for headings and bearings. It's great practice and I hope I'll ace the exam this way.
We use the random number generator for determining what events take place in our simulated political landscape. The administrators develop probabilities of likely outcomes of a certain event, then use the random generators to determine which events take place. It's very useful, thanks!

I study the life-cycle of viruses, and I perform lots of tissue culture experiments. In order to try to develop theories to explain some results I was getting, I wrote a computer program that uses a Monte Carlo scheme to simulate infection of cells by viruses. I need a different random number for each simulated virus, in order to randomly assign it to a cell that it ‘infects.’ In order for the results to be meaningful, I need to simulate tens of thousands of ‘cells’ and hundreds of thousands of ‘viruses,’ so I need hundreds of thousands of random numbers. The pseudo-random numbers produced by the Apple Macintosh built-in linear congruental generator proved themselves to be not good enough for the job, as I found that some numbers were chosen too often, a definite no-no for my purposes. Then I saw the NY Times article about this site and gave it a try. First I tried using Random.org numbers to seed the Macintosh generator at frequent intervals during the execution of the simulation, but it did not solve the problem. So I tested using all numbers from this site and they passed my quality test. So now I download several batches at a time of 10,000 numbers between 1 and 40,000 and string them into big files as the sources of my numbers. I'd like to be able to download them in even bigger batches, though. Thanks for a truly useful service!

I used your random number page to get truly random numbers between 0–99 in order to study the Monte Carlo method for arithmetic solution of problems and to simulate the beta decay of nuclei. Thanks a lot, it saved me the trouble of having to input into MS Excel, 500 numbers, which were pseudo-random, anyway.
