In regards to Charlie Kirk's assassination, has anyone thought about crowdsourcing the videos people took at the scene to triangulate the shooter's location based on measurable delays in the audio? If phone videos from different spots were gathered, they could be synced and the delays in when each mic hears the gunshot (sound travels only ~343 m/s) could be measured. With as few as 3 - 4 video clips from varied locations (but better accuracy with 10+ video clips), the shot’s origin can be triangulated to within 10 metres. No need to wait for authorities who seem to be playing games or at best plain incompetent. The community could analyse and map this for ourselves. It’s a little sophisticated but absolutely doable.

Just watched an absolutely fascinating talk by nostr:nprofile1qqsfgg2lg25kxdwg0l9eazq6pwak9wd8j4geuyyu7hua9mmpw6qlvgspr3mhxue69uhkummnw3ez6vp39e3x7mr59ehkyum9wfmx2uspr4mhxue69uhkummnw3ez6ur4vgh8wetvd3hhyer9wghxuet558z299 about his new product, Beacon. It’s a wonderful example of using your opponent’s strength against them. Beacon brings Bitcoin Cashu wallets, AI tools, uncensored news, and more, all through a simple text box inside WhatsApp. In countries like Myanmar, where WhatsApp is often the only reliable form of communication, this approach is brilliant!!!

So I wanted to deep dive on the old NONCE attack on hardware wallets, specifically whether the COLDCARD Mk4 leverages each of it's True Random Number Generators (TRNG) on both secure elements to generate random numbers and combine them using XOR. Checking out this blog post... and HOLY SHIT, my respect for COLDCARD's security just skyrocketed. They don’t just use both secure elements but they also throw in the Microprocessor’s TRNG and XOR them together, with all of them chatting over a few millimeters of copper via encrypted comms. And that’s just scratching the surface! No wonder nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 loses his mind when people use Raspberry Pis as hardware wallets.
