Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I’m currently in the process of building a Safu Ninja metal seed storage and have a question about BIP 39.
try this tool for plausibly deniable steganographic encryption of BIP-39 mnemonic seed words. It is very cool but keep in mind you need to be careful each time you add complexity to the whole process https://github.com/mifunetoshiro/Seedshift/

Seedshift - steganographically encrypt your seed words
Pertaining to recent events (both the FTX collapse and LastPass hack), self-custody of your crypto and with it safe backup of your mnemonic seed words has never been more warranted I think. I keep my seed words secured in a local KeePass database in a few different places, but this guy kept them on LastPass. I wrote this script a few years ago to be able to securely write them down in an easy human-readable format and not have to worry about it even if a thief/hacker came across them: https://github.com/mifunetoshiro/Seedshift

where do you keep your seed phrase?

Your seed phrase: Some of the worst mistakes you can make when storing your seed. And some tricks to help you store it better.
I developed a method that steganographically encrypts your seed words in a plausibly deniable way using a date-shift cipher: https://github.com/mifunetoshiro/Seedshift

Brute-forceable puzzle - free crypto for whoever manages to crack it
There is an x amount of crypto I put there as an award for whomever manages to get ahold of it. It is encrypted with a date shift cipher using this script I wrote: Seedshift. I basically used 1-4 dates in YYYY-MM-DD format to shift the mnemonic words (modulo 2048 to wrap around the wordlist, you can do it manually without the script).
-
PSA: If you use a cloud service (e.g. LastPass) to store e.g. 2FA recovery seeds, backup it on another cloud service or locally with KeePass
Also, it's not recommended nor safe to store seed words directly in plain-text in either cloud or local backups. If you do, at least obfuscate them somehow. I personally use a date shift cipher when writing down/saving my seed words (https://github.com/mifunetoshiro/Seedshift) which you can also do by hand.

Memorizing your seed
I use a date shift cipher on my seed words, so even if someone comes across it, it would be useless for them. I wrote a script for it: https://github.com/mifunetoshiro/Seedshift

dicebip39 - DiceBIP39 - bitcoin BIP39 seed mnemonic diceware table - dice are used to randomly pick your seed words. DiceBIP39 makes sure all words have the same odds. Coldcard, SeedSigner, Blockstream Jade, and some other hardware signers calculates the last word for you. Casino dice should be used.

btcrecover - BTCRecover is an open source wallet password and seed recovery tool. For seed based recovery, this is primarily useful in situations where you have lost/forgotten parts of your mnemonic, or have made an error transcribing it. (So you are either seeing an empty wallet or gettign an error that your seed is invalid) For wallet password or passphrase recovery, it is primarily useful if you have a reasonable idea about what your password might be.
