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.

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.

As XRP Toolkit doesn't support Trezor, is there an alternative way to use SetRegularKey on my Trezor to be able to register for the Evernode Airdrop via Xumm?
The official SLIP-0039 standard itself confirms it is not possible to convert this mnemonic type to BIP-0039. Down in Section 9 "Compatibility with BIP-039":

Shamir Secret Sharing
For anybody new or returning to SSS, check out SLIP-0039: https://github.com/satoshilabs/slips/blob/master/slip-0039.m...
One of the big downsides of SSS is that it’s very raw and you have to do a lot of legwork to make it actually useable. It’s rightfully criticized for this and the argument follows the don’t roll your own crypto vein.
SLIP39 solves this by formalizing a protocol for handling SSS splits built atop standards for crypto key serialization (BIP-39). SlIP shards are unique on each generation so parties with the same underlying SSS shard can’t compare mnemonics, they’re mnemonically serialized, and have a checksum and group index metadata which makes a more sane UX possible when combining.

Trezor-T XMR Account Recovery (do not use, sample only)
Well every wallet chose to solve this problem independently. Trezor proposed a new standard called SLIP10 to do BIP44 type operations coins that did not use secp256k1. Problem is, there are very few utilities I've found that will do SLIP10 derivations.

Reminder: Trezor Shamir Backup is fundamentally secure
They use an open source algorithm which is documented here. Anyone can verify it and the recovery outside of a Trezor hw-wallet is possible if required.

Article explaining how Ledger Recover works
It will be using SLIP-39, like Trezor and Electrum, or a Ledger rewrite of it. All the language about shards is straight from the SLIP39 spec.
- Is it possible to have both BTC and XMR keys stored on the same Trezor at the same time?

Simple sample script to dump Trezor Coinjoin taproot addresses

Simple sample script to dump coinjoin taproot addresses
With the introduction of the new Coinjoin feature in the latest release of firmware and software, I had the need to dump some of my taproot derivations. Although blockbook can do this fine using descriptors in place of xpubs for taproot accounts, it fails on Coinjoin accounts. This is likely because SLIP-25 as 6 deep derivations while BIP-86 uses a standard derivation depth of 5.

coinjoin funds accessible to other wallets?
The recovery of Coinjoin accounts is described here. Accessing them outside of Trezor Suite will 100% destroy all privacy obtained since Suite is the only keeper of the anonymity set for each UTXO. Using your CJ coins outside of Suite may also erode the privacy of previous transactions using your Suite Private coins as well.
