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.

A Critical Analysis of the What3Words Geocoding Algorithm
Pluscode is a trademark. The actual standard is called "open location code" and is unrestricted - https://github.com/google/open-location-code/

Evaluation of Location Encoding Systems
Yeah, that seems like a bad design choice. If you look at the spec [0], you can see that they only use "23456789CFGHJMPQRVWX" in the codes. They apparently scored the letters based on how well they can spell 10000 words in 30 languages, without thinking about character similarity. If they had involved actual humans instead of counting letter frequency, they might have noticed that the letter W looks similar to VV, and that its English name is "double U". And tried a letter like N or Y, which would be much harder to confuse.

Houses having names instead of numbers.
I wish https://plus.codes/ took off. The benefit compared to what 3 words is that you can use the closest city to give directions and cells next to each other share the bigger cell name.

r/Starlink Questions Thread - March 2022
New to this so sorry if this is stupid. I've been trying to use https://plus.codes to try to check an address for availability at starlink. Whatever code I put in, it simply tells me afterwards "please enter an address or a plus code". That website seems to give me either a shorter or a longer plus code. Neither of them seems to make the starlink website happy. When I try putting in the address, it doesn't like that either. Confused on where to go from here.

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.
