The Guinness Brewer Who Revolutionized Statistics
William S. Gosset, discoverer of the Student's T-Test. Amazon should have taken note of this trick:
Upon completing his work on the t-distribution, Gosset was eager to make his work public. It was an important finding, and one he wanted to share with the wider world. The managers of Guinness were not so keen on this. They realized they had an advantage over the competition by using this method, and were not excited about relinquishing that leg up. If Gosset were to publish the paper, other breweries would be on to them. So they came to a compromise. Guinness agreed to allow Gosset to publish the finding, as long as he used a pseudonym. This way, competitors would not be able to realize that someone on Guinness’s payroll was doing such research, and figure out that the company’s scientifically enlightened approach was key to their success.

tinystat - GoDoc
tinystat is used to compare two or more sets of measurements (e.g., runs of a multiple runs of benchmarks of two possible implementations) and determine if they are statistically different, using Student's t-test. It's inspired largely by FreeBSD's ministat (written by Poul-Henning Kamp).
