    There are different kinds of infinity

    “Countably infinite” means an infinitely-large set of numbers that could be generated by infinitely following an algorithm with a finite number of steps. For example, natural (positive whole) numbers are countably infinite because they could be generated by following this simple algorithm:

    1. Start with the number 1
    2. Add 1 to your number
    3. Repeat step 2

    The set of real numbers, on the other hand, is uncountably infinite because you can have an infinite number of digits after the decimal place. You can’t define a finite generation algorithm like the one above simply because any precision you use wouldn’t cover the full range. In other words, if you wanted to modify the above algorithm, and chose 0.1 as your starting number, your algorithm would miss 0.01. If you chose to start at 0.01, you would miss 0.001, and so on











  • Everyone else is gonna be like “if you don’t have at least 3 backups of something blahblah” but you know, not everyone has the finances for that, so advice from a cheapskate computer nerd: when going through critical transfers/reformats/deletions like you were doing, ALWAYS try actually recovering stuff from the backup before you cross the point of no return. E.g. if the backup is a .zip, extract a few individual files from it and open them in their respective programs.
