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.

Is 0.1 Bitcoin good to buy a Hardware wallet?
If you really want to up your security game, I would take a look at The Tordl Wallet Protocols which are holistic guides on how to properly store your bitcoin. It includes info on hardware wallets, backups, inheritance, multisig, and a lot more.

Covenant opcode proposal OP_CONSTRAINDESTINATION (an alternative to OP_CTV)
I have the proposal for this opcode up here: https://github.com/fresheneesz/bip-efficient-bitcoin-vaults/blob/main/cd/bip-constraindestination.md. I'd love to hear what people think about it, what problems it might have that I've missed, or other issues or suggestions surrounding this. I'd also appreciate any input that would help me improve the presentation of the opcode.

Let's talk about Bitcoin Smart Contracts!
I guess if pressed, I'd have to define a smart contract as a Bitcoin script involving more than one person. Lightning is one. Another one I'm looking forward to is wallet vaults where you have a third party controlling one key in a multisig like address. The third party can help you recover if you lose all your keys, but can't steal from you (unless, again, you lose all your keys). Also, I created a proposal for a wallet vault where in one transaction you could send money to someone else directly from your wallet vault while still having buffer time to reverse the transaction in the case it was a mistake or theft attempt. If those kinds of things count as smart contracts, they're pretty interesting to me because they could make self custody far easier and more secure.

This is how easy and simple it is to send a Bitcoin payment in El Salvador. It really feels like magic internet money.
Who pays the escrow with credit cards? Merchants do. But escrow is basically costless on transactions where they don't have to intervene. You could construct a smart contract that automatically releases money to the recipient after a time lock (eg using this hypothetical opcode), and the escrow only needs to be paid if their intervention is asked for. Who would pay the fee? It's a service for the payer, so the payer should pay that fee. Payers would happily pay a little bit to get their money back i think.

Jack Dorsey has questions about how to develop a new hardware wallet. What are your answers?
To get wallet vaults, we need covenants. OP_CHECKTEMPLATEVERIFY can do that. However there are limitations. But the benefits are significant enough to make the limitations acceptable. I think we can do better tho, which is why I'm working on this.

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.
