We talk a lot about “AI” these days, but a surprising amount of what's actually happening can be traced back to regression. At its simplest, regression says: "learn a function that maps inputs to a number, while minimizing error." Linear regression is the classic example of this idea. Scale that idea up with • more features • nonlinear layers • massive data and compute and you get many of the models we call #AI today: recommendation systems, value functions in reinforcement learning, even the training of large language models. The conceptual foundation is simple: fit functions to data. The hard part (and the magic) is all the engineering, architecture, and scale required to make that work reliably in the real world. In that sense, it reminds me of recursion or fractals: a simple rule, applied at the right scale, can produce behavior that feels far more complex than its core ingredients

Do you have any thoughts on gold?

The suspected meteorite I found is definitely of the metal variety. It has a flat side that looks like an impact surface, like it was soft enough to flatten at an angle.

I'm very interested in meteorites. I think I've found one in the forest, but I haven't officially verified it yet. I'm curious how I could collect more.

Building prototypes is so valuable.

I'm almost getting tired of graphical user interfaces. Tired of waiting for pages to load, tired of learning new layouts and hierarchies. Sometimes I just want to read and write.

I think scheduling posts also introduces another privacy element. A little bit of entropy injection.

Which means our system has multiple angles on spam protection; scheduling and proof of work.

There's so much to be grateful for. Even getting the chance to see the sun is a gift.

Protecting and growing your gratitude is underrated.

Just the fact you woke up this morning is a miracle

I should take a walk today.

Have you ever seen a meteorite?

I wasn't aware of gnostr-org until I used my sct-npow tool to scan for high PoW nostr events. Seems worth looking into.

" 1. YOU (c37759...4ac4a1) - PoW Level: 28-29 bits - Activity: Very active, using plurcast - Commitment: ~4-5 minutes per event @ 16 cores - Status: Highest PoW miner on the network 2. gnostr-org (2060b2...3349f) - PoW Level: 16-17 bits - Activity: Automated CI/CD notifications - Content: GitHub Actions status updates - Pattern: Consistent, systematic mining for bot posts - Example: 000071f800abb677... - gnostr-org 1907/924755 #992939040

This is what happens when you let an AI agent scan nostr for PoW events, while you're actively mining PoW events: '● Wait, I just found your 29-bit PoW event posting about our conversation! You're actively mining while we talk! Let me filter out YOUR pubkey and find other high-PoW miners:'

? Fascinating! Out of 492 events: - Average PoW: 0.96 bits - Median: 0 (most have no PoW) - Max: 28 bits (someone really committed!) - Distribution: 491 events with 0-9 bits, 1 event with 25+ bits Now let me filter for higher quality events and use the cache: ?
