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 wrote my 24 phrase on a text edit on mac offline. I directly saved it to an Encrypted Usb Drive. I unmounted the drive, then turned wi-fi on after it was ejected. Should I be safe?
If you are going to take this route, I'd recommend using Shamir Secret Sharing to split your key into shares, of which you can choose some number required to reconstruct the original key (like 3 shares, any 2 can recover the key). Keep the shares in disparate locations, maybe one on your encrypted usb, one in a safe, one in a bank lockbox, one with a trusted person...

Where to Store Ledger Wallet Seed
This is not good. By finding just 1 share a potential attacker has reduced the time needed to crack your phrase thorough brute force 96 sexdecillion times. Check out this amazing video about the Shamir Secret Sharing scheme which allows secrets to be split up in such a way that no useful information is revealed until the required number of shares are put together. Personally I used this repo to generate SSS shares.

BIP39 in 180 Lines of Vanilla JS — Mnemonic Generation, Validation, Seed Derivation, and the Japanese Wordlist Trap
For English coverage, Trezor's vectors.json ships 24 [entropy, mnemonic, seed, xprv] tuples — 128/192/256-bit, all with passphrase "TREZOR". For Japanese, bip32JP/bip32JP.github.io ships vectors with the ㍍-containing passphrase, so you can land all four pitfalls above in one assertion.

Give people something to link to so they can talk about your features and ideas
You got me curious- so I looked into this. Its called BIP39[1]. I made a quick proof of concept to generate 6 word phrases from a youtube url using the same wordlist[2]

Need help understading BIP39
Yes. BIP39 defines a check word to ensure the previous words are correct. You can read the spec here: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki

What happens if I lose my cold card device?
ColdCard follows the BIP-39 standard for encoding the wallet's seed as a series of 24 words (a.k.a. "seed menmonic", sometimes called a recovery phrase). If you followed the instructions you were given when initializing it and you've stored your seed mnemonic safely in the real world (not digitally where it can be more easily discovered), you're fine. In the event you lose or damage your ColdCard, you can initialize a new wallet--ANY wallet that follows the BIP-39 standard, which is pretty universal these days--and the wallet will regenerate the same private keysthat your original ColdCard did, in the same order.

Can the private key of a 24 word seed + passphrase be the same as of a different 24 word seed without passphrase?
Look-up "BIP32", "BIP39" and "BIP44", those will point you to documents describing precisely how seed phrases are converted into crypto keys.

is there a way to programmatically generate a wallet from a 12 word seed phrase that would give the same result in metamask?
i think bip39 is what you want to look up.
What are some alternatives?
