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.

Tyoe of Shamir's Secret Sharing used in Ledger Recover?
I am very sure it won't be. Trezor and Keystone use SLIP-49 which has some shortcomings which were improved upon by SSKR.

- Can ledger create something like Shamir backup, where users can manage the shards by themselves?

Isn't a strong bip-39 passphrase enough?
SSKR is an improvement on SLIP-39. SSKR comes with a seedtoolcli. Tezor hardware wallets use SLIP-39 if you have one of those.

SSSSS - Non-native Shamir Backup for seed phrases
SLIP-0039 is not is not round-trip compatible with BIP-0039. SSKR / BCR-0011 is based on SLIP-0039 but improves upon it by adding this compatibility.

Splitting BIP-0039 Mnemonic
Please see the discussion here: https://www.reddit.com/r/ledgerwallet/comments/ibkls4/does_ledger_have_plans_to_implement_shamir_secret/ Maybe ask here if the Ledger developers nicely if they still plan to implement Shamir's Secret Sharing, If Ledger do not implement Shamir's Secret Sharing (e.g. SSKR) then maybe consider purchasing a Trezor which implements SLIP-39. Bear in mind that SLIP-39 is not round-trip compatible with BIP-39.

Getting MultiSig Protection with a Single Hardware Wallet - Could be a better solution.... For personal vault
Or use a single hardware wallet that implements a version of Shamir Secret Sharing (SSS) e.g. SSKR and store your steel share backups in multiple locations.

Understanding and avoiding visually ambiguous characters in IDs
Modern bitcoin addresses use a base-32 character set that leaves out some of the most ambiguous pairs and also permutes the address ordering so that the most visually similar remaining characters produce single bit errors which are better handled by the addresses error detecting (and potentially correcting) code.

Bitcoin Block 840000
Context: Bitcoin miners have just adopted a 50% pay cut for themselves. This pay cut was baked into Bitcoin protocol at the launch of the network (mostly, see "BIP 42" [1]). The OP link gives information about the block in which this pay cut was made.
I get that HN comments tend to dismiss Bitcoin. But the fact that for the fourth time this pay cut has happened without a hitch speaks volumes to what makes Bitcoin interesting: It's a rare combination of economic incentives and technology that keeps chugging. Nobody can stop it. And it's extremely resistant to change. It requires no governmental approval. All attempts at subversion or interference have failed. There aren't many things that come close to that kind of record.

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.
