I have build an AI-Mermaid-Chart-Generator and tried a difficult prompt (Palestine/Israel):

flow-scribe-magic-words

Lovable Generated Project

The chart gives a walkthrough of events. I downloaded the SVG, made a PDF out of it, and gave it NotebookLM from Google, this is the result of the AI generated podcast https://notebooklm.google.com/notebook/75835e6c-7cdb-4d0d-bc5d-d98fbd1930bd/audio https://blossom.primal.net/e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

NotebookLM is nice but the app is 100% vibe coded, horribly bad

Tomorrow I will add „pay with lightning“ and nostr wallet connect. Flow chart generator and share and edit and fix

Found those mermaid things very helpful in developing complex code bases.

Mermaid Chart

Mermaid Chart makes diagramming simple: create and edit flowcharts, sequence diagrams, and more online. Collaborate in real time and save hours.

Forked Bitkey and got the server running locally

Hey @Bitkey @npub1tcnv...ctu0 I was able to successfully fork and build your server locally on my Mac, what a good code base!!

As soon as Bolt, Replit, Lovable, Cursor, Windsurf, Aider, Cline, Roo, Codex and Co. are good enough we are going to re-build every SaaS tool into a Bitcoin Lighting Powered 402 paymentrequired.com !

Building a FIDO2 Biometric Passkey gated MPC Bitcoin Wallet

Inspired by messengers, signal, whatsapp and co. i believe automatic phone verification (without manual code entry) like this, is one of the best user experiences out there to get started quickly.

Love the new keycard hardware wallet with type c reader for the laptop for $25!

Kind of what Nuri.com does for Bitcoin with a Biometric Smart Card (tba.)

I want to fork an open source bitcoin and lightning wallet that supports NFC to strip it down to be as easy as albygo but with an NFC hardware wallet for co-signing (multisig or mpc). Which wallet has the best base to do so? All suggestions are welcome, looking at Breeze and Green but there are so many I need input 🫆
