Yikes, that's a bad ngu.

Too much travel the last few months. But pretty uneven 2025 in general. Looking forward to staying home for a while and getting back to some discipline.

12-13% is my usual comfortable target. Pretty easy to get there without doing anything extreme.

Tried to tell @nprofile1q... not to look at the bitcoin price but she looked anyway.

Hodling her and our sats. Everything will be okay.

Hoping to clarify what seems to be a misunderstanding by @npub1qny3t... about how the Pi Zero hardware shapes the @npub17tyke... security model.

(see: @npub10uthw... #320)

I'm not about drama, certainly not looking to increase it.

Please give this a read and hit me back w/any questions:

Any 9mm pistol aficionados here?

I'm trying to narrow down my options for a home defense pistol.

* CZ P10 F (optics ready) is my top candidate
* S&W M&P M2.0 full size (optics ready) in the mix
* Walther PDP fading but still on the list



I haven't shot any of them yet, so it's all subject to change.

Anyone have any experience with any of the above?

Why no Glock? The chunky grip is a non-starter for me; just always feels a bit too big for me to secure a solid grip on. I'm not a super-experienced shooter so I need to feel confident that I can control it.

I'm prioritizing grip fit / ergonomics and recoil / muzzle flip control (thus the CZ and not so much the PDP, or so I'm told).

Why full size? I'm not in a carry state. Main use case is home defense and just overall pistol training / skill building.

Slides are up!

tldr: Payjoins / Coinjoins on hardware wallets is no bueno.

* Quick intro to payjoin and coinjoin cooperative spend transactions
* All the things current hwws / signing devices get wrong when displaying these txs to users (yes, @npub17tyke... blows it, too)
* Work-in-progress R&D on some better approaches.

I totally forgot to mention in my talks at @nostrich that you can derive a Nostr key from a BIP-39 mnemonic backup phrase.

* You (or more likely your Nostr client app) generates a new mnemonic backup.
* Write it down and protect it just like a Bitcoin seed.
* Client app derives your Nostr key from that seed.

@nostrich, @nostrich, @nostrich, @nostrich for app-generated Nostr keys, it'd be nice to go through NIP-06 derivation (`m/44'/1237'/0'/0/0`) and provide the mnemonic as their backup.

Eventually when we get keys out of browsers, we'll want more robust backup solutions. May as well piggy back on what's already out there (e.g. steel plates) for Bitcoin.

Can generate BIP-39 -> NIP-06 keys via https://nostrtool.com

Huge props to @nostrich! His `python-nostr` library is what's powering https://nostrtool.com!

This and the #nip26 @nostrich work is why I've been throwing so many PRs your way!

Part 3: Eventually Nostr client apps can directly integrate this @nostrich airgapped #nip26 exchange and streamline the whole process.
