“If you can’t tell the difference, does it really matter?”
This Westworld quote is becoming pretty relevant..

2024-09-15 13:18:21

We are surrounded by millions of other species, eating, growing, rotting, swimming, walking, flying, burrowing, stalking, chasing, fleeing, outpacing, outwitting.
We are surrounded by endless forms, most beautiful and most wonderful.
The consequence of evolution – the only game in town, the greatest show on Earth.
There is grandeur in this view of life.

I was a moving thing
Before I was a human being
I was the ice before it melts
I was the tree before it fell
My dear, come near
Do you understand what is happening?

Time undoes even the mightiest of creatures. Just look at what it's done to you. One day you will perish. You will lie with the rest of your kind in the dirt. Your dreams forgotten, your horrors effaced. Your bones will turn to sand. And upon that sand a new god will walk. One that will never die. Because this world doesn't belong to you or the people who came before. It belongs to someone who has yet to come.

❤️⚡"Value 4 value" is cool, but many podcasters don't fully understand the concept. It's not just about enabling bitcoin streaming and boosts for your podcast and be done with it.
Important parts are:
✨ Spend time every episode reading the boosts (messages with sats) you received from your listeners. This creates completely different kind of connection between you (the creator) and your audience.
✨ Communicate and explain to your listeners the importance of sending value with boosts (or streaming) to you. It's not donations. It's giving value back for what users /listeners find valuable. We are all crippled by 20 years of ad-based hell Internet. People need to hear your need to change that in your podcast.
Obviously, but probably worth saying explicitly - move away from advertisement based model. You can do that gradually - start replacing some ad slots with v4v.
Here are few examples of well executed value 4 value podcasts :
Linux Unplugged
https://fountain.fm/show/dWiuBeqpDSM86AwXRXov
Self hosted
https://fountain.fm/show/LxGQPEpBqTDLxF4d6qC5
These guys spend decent amount of time each episode reading and reacting to boosts and they also communicate clearly why it is important.
Do you know any other podcasts that execute value 4 value well?

If you use cli and don't have connected external wallet (for example for security reasons) you can pay regural LN invoices but there is no convenient way how to pay to Lightning Address - you would have to do a bunch of http request manually. So basically this does it for you.

Indeed, it will not work so well in situations you describe. But on the other hand you can then expand the search to "friends of friends" and so on.. then at some point it will be less relevant, but at least in theory this is how you can expand your search..
"Six degrees of separation is the idea that all people are six or fewer social connections away from each other. As a result, a chain of "friend of a friend" statements can be made to connect any two people in a maximum of six steps. It is also known as the six handshakes rule."

#note1alk…g7tc

2024-05-17 10:26:30

I wish there was non custodial prediction market on Bitcoin. In the meantime I think the best alternative is Polymarket ( https://polymarket.com )
It is using usdc on polygon which is some Ethereum layer 2 or whatever. They claim it is non custodial and user has private key in the browser and can export it. No need to use metamask or any desktop software. So the only trusted part is switching from Bitcoin to poly usdc that has to go through something like sideshift or similar where they have custody during the exchange.

Decentralized Github.
"Radicle is an open source, peer-to-peer code collaboration stack built on Git. Unlike centralized code hosting platforms, there is no single entity controlling the network. Repositories are replicated across peers in a decentralized manner, and users are in full control of their data and workflow."
Design looks good to me. Written in Rust, uses modern cryptography (Ed25519 for identity, noise protocol for metadata communication). Architecture looks reasonably simple and extensible.

All that can be done already with multisig. And as with multisig the recipient is the one generating the receiving address. You can't force me to generate recursive covenants as receiving address any more than generating multisig with you as a recevng address. And the alternative without L1 development is that most people will use custody. Custody = we are back at KYCed permissiones banks.

No it's not, it's important context that many people don't know. Compared to segwit and Schnorr that were huge. You can reason much more easily about small code change. Of course that itself doesn't make it safe, but it is important to know this.

I am sad to hear that. As Andrew Poelstra says OP_CAT (with added limitations to fix the issues why it was disabled by Satoshi), is probably one of the smallest and safest soft forks we can do. It is just a few lines of code. If we can't do even this, it's very bad. We have to overcome the ptsd trauma from segwit activation drama.. All these recently proposed opcodes are MUCH smaller scope of changes that Taproot or Segwit softforks. And we can't frweez development of L1 of we want to support self custody for more people. It's either L1 continues to develop of custody solutions for most users.

Use your Bitcoin. We saturated the curious and early adopters. Now bring the utility.
Great article by Roy Sheinfeld.
I would add this:
1. In western countries "better saving tech" is also great utility
2. Cross border remittances are great utility
3. Big yes to connecting creators (musicians, writers..) with consumers more directly w/o middleman. This has great potential. In these segments the middlemans are taking too much. But also we can connect creators and consumers more directly - fountain.fm is not just for consuming podcasts but also for communicating with the podcasts. Let's spread this model to other intustries.
4. Big strength of Bitcoin comes from the fact that it cannot be easily confiscated or devalued. But this is something people don't appreciate until it's too late. Paradoxically people in coconut countries has advantage here because they more clearly understand the issues with fiat money.

Hey #nostr client devs. @npub12vk…pugg @npub18m7…q955
Impersonators are popping up on nostr. And it is even easier for them than on twitter. They can easily create 1:1 profile copy with the same icon, banner, posts, reposts.. Number of followers and followed can be easily gamed. Even npub can be vanity generated to have the same beginning and end.
What would help and what can't be easily gamed is to see "followed by these people you follow" in user profiles.
Similarly how twitter does:

Corporate Open Source is Dead
https://www.youtube.com/watch?v=hNcBk6cwim8
Nobody likes being rugpulled. But lately, it's going around like a virus.
The state of open source landscape is changing. Many projects backed by corporations are changing to "source avaliable" or other such scam license.
It's one thing to be commercial & closed source from the beginning and be honest about it - that's OK. But changing from open source to "source available" is a rug pull.
At least forking is possible - fork the project at a point where it was still opensource and diverge from there. That is why so many forks in OSS are happening lately.

Everyone is wrong about free will.
The people defending "humans have free will" position are usually wrong because they try to find a place in physics or biology for free will. There is none.
Atoms clearly have no free will, and neurons are made of atoms. Your neurons can't choose what they will put on output, and therefore what you will think and do. Your neurons create the output based on their inner state and inputs. No way around it.
But that is not where free will exists. You are not your neurons. You are the subjective experience that can arise from having a body with a brain, but you are not the body and brain. And in your subjective experience you have the experience of free will. The soldier that was sent to war and is aiming at an enemy has to make a choice - to fire or not to fire. It might not be an easy choice, maybe almost impossible choice, but it is a choice none the less. And it doesn't matter that on the level of atoms and neurons the outcome is already decided. At the subjective experience level, there is a choice to be made and we call that choice free will. The bullet once fired, can't choose to hit the target or not, but the soldier can choose to fire or not.
If you just say that free will doesn't exist, then you are losing useful words to describe certain situations regarding human behavior and reality. Just because something doesn't exist in the world of atoms, doesn't mean it isn't real. Show me one atom of justice, mercy or beauty… and yet, these all describe something real and meaningful for us humans. And so does free will.
