If you're just looking to get into modern torrenting, start here: https://trash-guides.info/

If you're ready to put it into action, you might want a network attached storage device (NAS) to run your *-arr stack and store your stuff. I recommend a Synology NAS with at least 4 drive bays and a redundant drive.

You should do all of this behind a VPN. I recommend Proton.

My rig is set up to run in containers with docker-compose. I automated it all to the point that I just have to boot up my NAS and the torrenting starts up automatically. It's all managed through websites hosted in various containers on the NAS that I can access from any other device on my network. You can read the docker docs here: https://docs.docker.com/compose/

LinuxServer.io is also a fantastic resource for docker containers: https://docs.linuxserver.io/

Also, it's a good idea to run pi-hole for a network-wide tracker-blocker and ad-blocker. You should have your pi-hole devices on your network as a separate device that doesn't do anything else. I have 2 pi-hole devices on my network. The hardware they run on is just the smallest Raspberry Pi's I could find at the time. I connected them to the network via WiFi and plugged them in behind a dresser in one bedroom and next to the wifi router in the other room.

I'm a contractor at a rocket launch service provider. The final build of the ground control software is compiled and deployed to the launch pad with debug flags enabled because of a "fly like you test" mandate.

Millions of dollars and tons of time invested by brilliant people are riding on rockets that are launched using software with debug flags because of an "if it ain't broke don't fix it" mentality and archaic test strategies.

Ackchuawually, this example depicts a squish and a translation. A true scaling would have the scaling being done in place, resulting in an overlayed and smaller rectangle.
