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.

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.

Question about wallet security
... and BIP-39
- If you broke your phone right now, could you still access your crypto?
-
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.

Is my maths correct?
Not correct See this: https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki

Generating and Working With ScriptPubKeys in Bitcoin Transactions
Bitcoin transactions involve locking funds in scripts, which can only be spent if those locking conditions are met. The part of the script that expresses these locking conditions are called ScriptPubKeys. On the other hand, the part that provides unlocking scripts to satisfy the locking conditions is referred to as ScriptSig for legacy transactions, and ScriptWitness for SegWit Transactions. These scripts are evaluated by a stack-based language called Script. This article will mainly focus on ScriptPubKeys.

Do you use 12 - 24 words?
There are 5 271 537 971 301 488 476 000 309 317 528 177 868 800 possible permutations of the bip39 wordlist found here: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt when using 12 word seeds. You probably have better change to win the lottery every week for the rest of your life than cracking a 12 word seed in correct order

SEC Charges Kraken for Operating as an Unregistered Securities Exchange
No one controls Bitcoin, because it's a protocol. Bitcoin Core is the reference implementation, but there are others, and anyone can create new implementations if they wish. Also, the Bitcoin Core maintainers can't just change something on a whim, because users would then switch to another fork. Maintainers (or miners or other groups) can't force their changes on users, because everyone can decide on their own which version they want to use.
The protocol development happens through BIPs (Bitcoin improvement proposals): https://github.com/bitcoin/bips
BIPs are discussed for years, before (and if) they are implemented, and basically everyone needs to agree on them, because no one wants to fork the blockchain, which could be devastating.

Recover Cool Wallet seed to a Ledger?
All the seeds generated from the CoolWallet (Number / Word) adhere to the BIP-39 protocol.

Hal Finney Was Not Satoshi Nakamoto
> users would be required to hand over control of their wallet to actually manage the massive proliferation of addresses needed
BIP32 solved this in 2012, and is used by basically all self-custodial wallets these days. https://github.com/bitcoin/bips/blob/master/bip-0032.mediawi...

Bitcoin and the dangerous fantasy of ‘apolitical’ money (2013)
> Which policy are we referring to?
* BIP 141 version bits and BIP 148 as a voting mechanism: https://github.com/bitcoin/bips/blob/master/bip-0141.mediawi... and https://github.com/bitcoin/bips/blob/master/bip-0148.mediawi...
* core developer votes: https://en.bitcoin.it/wiki/Segwit_support
* posturing and maneuvering: https://cointelegraph.com/news/samourai-wallet-intends-to-ru...
> It evolves in a decentralized and organic manner, devoid of any formal political process or voting.
Just because its voting mechanisms are informal, that doesn't make them not voting mechanisms.
