Multiple mutually-exclusive A-B tests available in parallel

Example code for selecting which A-B test to place a user in when wanting to run many tests. It's assumed a cookie or other state is stored with the user. Once a user is "in" a test they shouldn't be considered.

the number line approach

The number line approach uses a range of numbers between zero and one. Each test we want to run 'consumes' fractional space on the number line, with the remainder unoccupied. When an elegible user arrives at the experience —i.e. they do not have the piece of state or cookie indicating they're already

Tips for using PCD: https://github.com/kvannotten/pcd

... I also wanted [range downloads], but then I first used the seq and parallel programs. It's a very unix-y solution, but it turns out ids being integers is great. You may need to install and play with seq and parallel a bit, but this works for me:

episode downloads (echo must be removed for real downloading):

$ seq 4 10 |parallel echo pcd download mypodcast {}
pcd download mypodcast 4
pcd download mypodcast 5
pcd download mypodcast 6
