I’ve ripped a good number of blu-rays to network storage. If you’re looking for older, less popular stuff it’s the best option. And older releases are usually just a few bucks. The new stuff I torrent because I can usually find a decent rip, but for stuff I want to put in my library a rip from optical disk is the best, but not free of course. You can even do it for free, public libraries often have a good collection of older releases on optical disk.
Also why the seemingly arbitrary graduations, 24 hours, 60 minutes, 60 seconds. If it was say 10 hours in a day, 100 minutes in an hour, 100 seconds in a minute, seconds would be close to the same amount of time. Same with latitude and longitude, why 360 degrees in a circle with 60 minutes in a degree and 60 seconds in a minute.
