| Jul 14, 2014 at 21:04 | comment | added | pgreen2 | The percentage wasn't very important for my use case. I had a large file of data that I was running unit tests against and it was taking a long time to run. My solution was to use a portion of the file (around 10%) to speed up the tests. Since I am learning ruby right now, I took this as an opportunity to see how best to write the script. | |
| Jul 14, 2014 at 20:59 | comment | added | Cary Swoveland | "...pull out around 10% of the lines at random" will not do. You must define precisely what that means. You could say, for example, 8%-12% of the lines, but that still doesn't do it, because it lacks the criterion for choosing the percentage in that range. That's your job. You could say a random percentage based on a particular probability distribution (e.g., uniform between 8% and 12%), but what's the point? Better to ask for a specific percentage selected at random (e.g., 10%), and you determine that percentage elsewhere in your code. | |
