Passed 13 years a couple weeks ago and just passed 80,000 rep. Too bad hardly anyone asks on Stack Exchange anymore, in the age of text-generating clankers. End of an era.
Thanks to everyone that attended our @hrf.org Oslo Freedom Forum workshop. We hope you had fun and learned something! While we only had time to cover one project (Canary Bitcoin), Mo (Bitcoin Design Community) made her Claude skill file publicly available for all 🙌 github.com/mouxdesign/V...

Bitcoin Dev Project@bitcoindevs.bsky.social · 2mo agoCalling all freedom tech builders! We are seeking volunteers for a live design review @ @oslofreedomforum.com Making Freedom Tech Beautiful workshop. Freedom tech only matters if people can actually use it. Even the most powerful applications fall short if they feel confusing or too technical.
Transcripts from the recent @bitcoincoreorg.bsky.social Core Dev meeting are now up on Bitcoin Transcripts: btctranscripts.com/bitcoin-core...

Happy #Bitcoin Pizza Day! 🍕 On this day in 2010 Laszlo Hanyecz traded 10,000 bitcoins for 2 pizzas! It may seem wild to think about now but had it not been for people like him that were willing to use btc as a medium of exchange we may not be able to transact with bitcoin the way we can today.
OSS development could be fun if people saw you as a person instead of as free infrastructure to take for granted
Vlad-Stefan Harbuz 🌸@vlad.website · 3mo agoOSS burnout claims another project. On 2 Apr, an entitled user angrily asked the burned-out maintainer of nvim-treesitter to “go switch to something that doesn't require interacting with people”. The maintainer replied “OK” — and archived the repo, stopping development of nvim-treesitter.
mental health is also about maintaining boundaries the baseline for OSS contribution is "scratch your own itch", you don't need to spend time on features or fixing bugs that don't affect you, or people you actually care about. no one is entitled to support just because you make the code available

🧰 Too much bitcoin tech knowledge is trapped in videos and podcasts If only there was an easy way to unearth those insights and gems… 🤔 We wondered that too, so we redesigned Bitcoin Transcripts! 🚀
What's the deal with #bitcoin fees? How are they calculated? Where do they go? Let's have a look with a #DecodingBitcoin 🧵 A transaction's fee is equal to the total amount of bitcoin in the inputs, minus the total amount of bitcoin in the outputs.
Buckle up for today's #DecodingBitcoin🧵. It's a long one but we promise it's worth your time. Today we're going to break down how to sign a #bitcoin segwit transaction. We'll use a real example from the BIP-143 test vectors (that’s one of the segwit BIPs!)
New tool in Decoding Bitcoin! REORG CALCULATOR ⚒️ Computes the probability that an attacker could reorganize z blocks with a given % of the total network hashrate Here’s the probability of an attacker reorganizing 6 blocks with 30% of the total hashrate bitcoindevs.xyz/decoding/reo...
We’ve got a good #DecodingBitcoin🧵for you today. The topic? 𝐄𝐧𝐝𝐢𝐚𝐧𝐧𝐞𝐬𝐬, AKA the order of bytes in a computer’s memory. When we put it like that it sounds a little boring, but there’s something interesting, and dare we say 𝑎𝑛𝑛𝑜𝑦𝑖𝑛𝑔, about how bitcoin handles endianness…
