One of the things I almost never see mentioned in the various climate debates is the observation that Earth is historically on the cooler side and is rising from that very low base.
The planet has historically gone through multiple cycles of not having polar ice caps and then having them again, etc. Over millions of years. There's been a really long-term feedback loop there.
I'm not a climate scientist by any stretch, but I just find that general omission in public discussions around it to be interesting.

I don't think that is omitted from the conversation especially because compared to previous warmer eras with no ice at the poles, the change in temperature occurred over millions of years so life had a chance to slowly adapt. Which is not at all the same as what's happening now.

I love this analogy and I think shows a dichotomy in the nostr world. One side is trying to replicate Twitter where clients are aggregating feeds from many relays and making it feel more like a global public square. The other is thinking about smaller, niche communities with a barrier to entry of some sort (more akin to the early internet with forums). I think both can exist but I personally want to build for the latter and I think the latter is easier to monetize.
Interesting. So I suppose we definitely want to use proper sources of randomness and hope there aren't any bugs that can cause a pattern to emerge. Any thoughts on EdDSA and how it deterministically generates the nonce? Can this sort of thing be implemented in Bitcoin/nostr libraries (assuming it's good and solves the issue)?
If I understand correctly, you want to make sure that whenever you generate a nonce for your ECDSA signatures, they should be as random as possible and should never be reused because it's simple to derive the secret key from the signature and the nonce.
I imagine that in both nostr and bitcoin, this is known and applications are designed with this in mind? Is ensuring random, non-reused nonces that hard to do?
I think its three things: 1. Unfortunately because of shit coins, NFTs, blockchain grifters and all the crypto related scams (FTX for example), most people lump it all together, bitcoin included as worthless and scammy. It will take some serious PR work to distance bitcoin from those scams or some amazing app that make people look passed this association. 2. Most people's introduction to Bitcoin is by some tool who bought it trying to get rich quick so it is usually associated with investing instead of as a currency. First impressions are crucial. 3. UX. Getting bitcoin, you have to sign up on some exchange (associated with scamminess) or go to an ATM (sketchy). In the best case scenario, someone gifts you some bitcoin so you skip this part. Now storing it if you have anything of value is also strange and difficult. You have to buy a hardware wallet and learn about all of that. Even with a phone wallet, you learn about seed phrases and what it means and I imagine some people feel intimidated by the responsibility. I know most people I introduced this to did so I end up holding their corn -_-. And let's not get started about lightning UX. Anything non custodial is a nightmare for normies. And finally, say you got passed all that. Now what? Almost nobody will accept bitcoin for payment. You have to go out of your way to find merchants who will accept it and even then you're quite limited. I think if the UX could be better than what's already out there, people would use it. Or necessity will drive people to it (e.g. Africa or Latin America).
Just delete twitter. I remember when I had it, the excuses I made for keeping it "I follow good accounts with great info", " I only use it for news". It was all mental gymnastics, the addiction talking. After deleting and the withdrawals subsided, I immediately felt way better. I don't miss it at all, I don't feel like I'm missing out.
But this is exactly why you do want a purpose built device. I own a 2014 macbook pro and started using crypto currency in 2017. I started with shitcoins, now I'm only bitcoin. But regardless I had a wallet file saved to a USB stick but one day, I checked my funds and they were gone. I consider myself pretty computer literate and to this day, I still don't know how my wallet was swept. Was this laptop air gapped as you're proposing? No, but IMO that is way easier to fuck up than just using a HWW.
Question: would it be possible to do time based delegation? To be more clear, I mean say you have a nostr webapp that you'd like to use, so you create some delegated keys, those keys are stored in the browser (think JWT tokens) and eventually expire. And a new fresh pair can be renegotiated later. This would allow users to sign/send events using the app but without needing constant approval from the remote signer (I'm think a chat app that uses your nostr keys, it would be a pain to have to constantly use my remote signer as opposed to just using it once for a session). Is this kind of scheme possible or even advisable?
I'll be honest, my worldview changed after becoming interested in Bitcoin. Nothing wrong with changing your views when new information comes along. I'm still learning and changing my opinion on stuff today.
Oh if I understand what you're saying, if you have multiple values in the single letter tag
```json
{
"#t": ["gm", " bloom"]
}
```
The relay should interpret that as "events with the "gm" OR "bloom" as values for the "t" tag? And this proposal using "&t" would make "events with "gm" AND "bloom"?
This helped! Thanks. So I guess single letter tag filters just look like this?
```json
{
"#t": [
" gm"
]
}
```
Really random question: what do nostr tag filters actually look like? NIP-1 describes it but I'm having a hard time wrapping my head around it. Is there a sample tag filter somewhere?
I feel like this is a perfect example of cultivation theory. The media we consume (books, movies, shows, YouTube videos, etc.) are well crafted narratives where everything about that world is carefully crafted by an author. And that shapes our world view. But the world isn't like that. There isn't some author in control of everything. Sometimes things happen and there's no link. I feel like the Bitcoin/nostr space is filled with people who think this way.
Oh man I desperately want to see the salt in the comments but it's not worth making an account on that hellscape of a platform.
