A long time ago I adopted the Jinx’s Rating For All Things system and it’s served me very well. It is very similar to OPs suggestion.

• ⭐️⭐️⭐️⭐️⭐️: This thing is core to who I am. I don’t want to live in a world without it. The experience was life changing.
• ⭐️⭐️⭐️⭐️: I really like this thing! This will be in my rotation for along time. I had an amazing time!
• ⭐️⭐️⭐️: I like it. Perfect in the background. If it’s on, I probably will watch/listen, but I probably won’t seek it out. Inoffensive. This meets but doesn’t exceed my expectations.
• ⭐️⭐️: Not my thing, but I see why people like it. It has value, just not to me. I was slightly annoyed.
• ⭐️: Why would anyone like this thing?!?!?!?

I personally think the 5-star rating system is perfect. Any more than that and a lot of the mid-tier ratings become arbitrary and everything is subject to immediacy bias. Tastes change over time and how much you like stuff changes, but I’ve found that they rarely change buckets in this system.

I don’t understand why someone cares if they like one thing “just a little bit more” than another. It doesn’t have to be a competition. Do you like it or do you love it? Is it core to understanding you as a person? Did you have an amazing time?

I mean, you can, or you can use it to assure your firewall is configured correctly. The entire Internet is scanning you at all times, why would you focus your attention on one of the services who is willing to share their results with you?

Believe me, you probably have lower hanging fruit to pick.

Ironically, salt has probably killed more people than both Sodium explosions and Chlorine gas combined.

Musicbrainz Picard --> mp3Tag --> MusicBee

• Picard handles the initial tagging.
• mp3Tag handles the clean-up. I like things “just so”, and some of the time Picard goes rogue. The Actions function is super powerful for automating “fixing” tags. Oh, and you can cut, filter and paste an entire directory’s worth of song tags if you want to bulk remove a bunch of unwanted tags that Picard adds.
• MusicBee is the database. I like the Inbox feature that allows me to do a last check before “promoting” the files to my master library.

There are portable versions of all three, so you can lock a version in your music directory and never worry about updates ruining your tags.

Who?

I don’t do that for a living anymore

The answer is an SSH reverse tunnel. Have privoxy running in the rPi listening on localhost. Have it then connect to your home server via SSH with reverse tunnels enabled, tunneling the privoxy port. On your home server you run another instance of Privoxy that’s listening in your home network and proxy forwarding over the tunnel and you’re done.

I used to use this setup for pen testing.
