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.

Ask HN: Can 2 ledgers generate the same seed phrase out of millions out there?
Sure — with about the same likelihood as selecting the same atom out of all the atoms in the universe, twice in a row.
Besides; don’t. Generate your own entropy, save it as sets of SLIP-39 Mnemonic cards, and use the https://slip39.com App or https://iancoleman.io/slip39/ to recover your entropy (and your BIP-39 Phrase.

Convert Two 20 Word Shamir Backup to a 3 of 5?
If you are happy to set up an amnesiac, airgapped system like Tails and use a tool like this one https://iancoleman.io/slip39/ then yes. (Basically you would reconstitute your current shares to get a master secret, then create the desired number of new shares from that secret) You can then restore these shares into a Trezor and ensure that it is working as an expected...
- Storing entropy a SLIP39 solution for BIP39 devices?
- SLIP39 solution for non-SLIP39 hardware wallets?
- SLIP39 solution for future Trezor owner, current Ledger user?
- Any reason not to use this as SLIP39 solution for Ledger?

Which (on- or offline) wallet supports SLIP39?
Any hot wallets? Or can I just use an offline copy of https://iancoleman.io/slip39/ to use the shards to restore my seed and enter that restored seed in any "normal" wallet?

Binance has no proof of reserves for ETH/XRP, inadequate reserves for rest
Use https://slip39.com
Create a new seed (using your own dice tools to create good entropy).
Practice recovering your BIP-39 Mnemonic from your SLIP-39 Mnemonit cards.
Print out the cards, and decide who you’ll share them with. Send them.
Then, transfer your Bitcoin, etc. into the address printed / QR-coded on the card.
No hardware wallet required; later, use a hardware wallet to recover the account private keys, and use your coins.

Ssss: Shamir's Secret Sharing Scheme
Backup your BIP-39 Mnemonic phrase using SLIP-39 [0]
This saves the original entropy from which your BIP-39 phrase was generated, over several groups of multiple SLIP-39 mnemonics cards.
Later, recover enough cards from a few groups, recover your BIP-39, and recover your hardware wallet.
Much more reliable, and safer because an attacker must collect many independent mnemonics from groups they probably don’t know the members of.

Did I just lose half a million dollars
Use SLIP-39, and a hardware wallet that allows recovery from SLIP-39 shards (eg. a Trezor).
With BIP-39, you are simply going to lose your wallet, eventually. It's almost inevitable. Either because you lose the 12- or 24-word passphrase, OR because someone else finds one of your backups.
I've written a decent Python implementation, here, which is simple enough to review:
