Yep, sqrt(-1) = i. Powers of i are actually really neat imo since they form a loop: i^0 = 1
i^1 = i
i^2 = -1
i^3 (or i^2 x i or -1 x i) = -i
Now the loop starts:
i^4 = i^2 x i^2 = 1 x 1 = 1
i^5 = i^4 x i^1 = 1 x i = i
etc
Any evaluation of i to the power k boils down to i^(k%4). For example, i^726 = i^2 = -1. I know this was super useful in calc 1 or 2 and not used for any of my other math classes, it’s just a fun concept to me
Time machine + $100 for a lifetime subscription to nzbgeek. I got a lifetime subscription a couple months before they removed the option, only had it for a few months now but well worth the money already. Most of my shows, movies, and music come from it (supplemented by torrenting)
Usenet is usually a lot faster, for most things you can basically max out your bandwidth (or whatever the max you set your download client to) instead of it being determined by the number and quality of seeders. Newer releases torrents also download very fast, but after a few months or years the seeders drop off a lot, usenet is always the same speed even if it’s super old and most keep stuff indefinitely or for 10-20 years or so (longer if it’s being grabbed a lot still)
Also one nzb site is usually enough, you don’t need to check a bunch of different torrent sites since it’s basically one massive one. I use prowlarr so I have it check nzbgeek for everything first and a bunch of torrent sites as backups in case it isn’t there, but almost everything gets grabbed from usenet
Throw Linux on it or reinstall windows if you don’t want to learn Linux. I assume it’s a new PC, but you never know what may be on there regardless. A new install with a complete overwrite is the way to go imo.
For Linux, it personally use arch (btw) and love it but it’s not super beginner friendly. I’ve heard good things about Linux mint for beginners so that may be a good place to start
