In a thread on Bitcoin-Dev, several developers discussed changing or removing Bitcoin Core’s default limit for OP_RETURN data carrier outputs. A subsequent Bitcoin Core pull request saw additional discussion...

Is there a way to stream video via RTMP to nostr?
I suddenly remembered Mircea Popescu. Not sure why.

(if/when quantum computers become powerful enough to allow stealing bitcoins):
Pieter suggests the bitcoins that are still vulnerable are confiscated/locked/destroyed/made unspendable.
Parker suggests allowing the vulnerable bitcoins to be stolen.
Which way, quantum Bitcoiner?

After years of contributing to Bitcoin on nights and weekends, Sebastian Falbesoner has left his job to focus 100% of his time on Bitcoin open source development.
"After years of contributing part-time, I'm thrilled to fully commit myself to improving the Bitcoin ecosystem. A big thanks to Brink for providing the ideal environment to make this dream a reality! 🫡 " - Sebastian
Brink is proud to enable Sebastian's move to full time, but the credit goes to our supporters.
Thank you Samara Asset Group, Lightspark, Stakwork, Ledger, Bitwise, VanEck, and Jack Dorsey whose multi-year pledges show engineers that open source development can be a sustainable career!
Unchained did a write up about this structure which might help
Brink just received our first donation from a Bitcoin Donor-Advised Fund.
The donation was in BTC and made using a multisig onchain transaction.
This donation was made through Unchained's Bitcoin DAF and will be held in our reserves to fund Bitcoin development into the future.

Get cozy, its a long #Bitcoin Optech newsletter this week
Brink is excited to announce that Eugene Siegel has joined us as an open source engineer working on fuzz testing and Bitcoin Core development!
With a background as a security engineer working on Lightning and already disclosing multiple Bitcoin Core security vulnerabilities, we're excited for Eugene to help ensure the long-term security, resilience & decentralization of Bitcoin.
Welcome Eugene!
Today we celebrate Hennadii Stepanov's 4 year anniversary as a Bitcoin Core engineer at Brink 🎉
From a simple fixup because of an old laptop, to one of the most prolific contributors to Bitcoin Core today...
https://brink.dev/blog/2025/03/28/hebastos-brink-epoch/
Whether that is the build system, operating system compatibility, the GUI, or language translations, hebasto’s efforts have been aimed at making Bitcoin secure, accessible, and user-friendly.
Hebasto led a project to migrate the build system to a modern, CMake-based one, enhancing efficiency and paving the way for future development. The migration to CMake took nearly 300 pull requests, a dozen people, and two years of review and testing.
https://bitcoinops.org/en/newsletters/2024/09/06/#bitcoin-core-30454
Since his initial contribution, hebasto has 1800+ (!) commits to his name.
But it isn't just his own work...in the last year alone hebasto also provided nearly 1,700 review comments.
https://github.com/bitcoin/bitcoin/graphs/contributors
Brink and the Bitcoin community are lucky to have hebasto on our team.
Thank you for your open source #Bitcoin contributions, Hennadii 🚀

Marco does a good job explaining the context of checkpoints and their relation to things like assumevalid. Checkout from this timestamp:
