Whoever gave me this huge bag at Nostrica, THANK YOU!
Been using it super often since then and I love it!

Only sending updates would require the server to be able to sign the list on your behalf.
The whole point of nostr is to transfer control from server to the user.

the trigger for me to switch was when I tried to include the mempool app to nixpkgs. I got hammered cause bitcoin apps were supposedly bad for the environment at that time.
from that moment on, I figured a little decentralization was my way forward.

flakes also allow to pin version numbers, which increases reproduceability

2025-08-18 17:06:30 UTC

isn't it harder to track, compared to inputs and outputs in a flake? makes the distinction clear about what's included in nixpkgs and what I added myself.

2025-08-18 17:04:32 UTC

- reply

I'd like to understand the reason behind the flake hate... maybe I could learn a thing or two.
Without them, I feel shackled to what nixpkgs might contain or not.

Nevermind, I have tried again and now it works... that's weird... maybe I was in a shell that's in a shell within another shell that caused that flake dependency.

2025-08-18 15:50:34 UTC

- reply

I think they help with decentralization, which as a bitcoiner I tend to go towards... I use them all the time to package stuff so I don't have to wait for nixpkgs to do it for me.
Anyway, seems like I depend on a flake to execute the shell.nix but you don't. That's the point.

What if I make a pull request with a flake... would you accept it? It might also intall all the rust toolchain just by typing "nix develop".

Been a while I haven't used zaps here.
Asking "the AI" which is the best wallet to get a NWC URL from. All I get is hallucinations. So far, none of the options presented work.
So I am asking you, fellow nostriches... which setup are you using?

2025-08-18 15:05:11 UTC

Trying notedeck... one minute in, already loving it! Thanks @npub1xts…kk5s!
Thinking about contributing to it by adding a flake. Would be nice to be able to cleanly install it in my Nix home-manager.

What's the current state of nostr relay software?
I used to work on one in 2023 for learning purposes. Since then, my attention has been diverted to other matters, so it never came to be.
This automn, my attention will most probably be back on sovereign software development in full force.
Be it on nostr or Bitcoin, maybe I should focus on newer problems to be solved, hence my questioning.

Impermanence in NixOS is where your root directory gets wiped every reboot...
Add some bitcoin apps to the configuration and create an image with it.
You end up with a potential bitcoin bootable USB key that records nothing.

Nix is so cool… have you tried microVMs?
They can be compared to Docker containers, except they’re safer and easier to manage.
This is not to mention that all those config files totally are reusable. Once you configure a Bitcoin node with NixOS, you can reproduce that on another computer just by reusing code. Reminds me a lot of programming language libraries.
Oh, and setting up baremetal computers is done with the same exact concept. That means any config can be reused anywhere, in a virtualized environment or not.
Take a look at https://astro.github.io/microvm.nix/

Yo dawg…
Someone brought to my attention that Mempool seems to have forked Blockstream’s fork of Romanz’s electrs…
The README.md seems pretty similar to Blockstream’s aside from the fact that its sync requirements are a bit more up to date.
I would like to know what else have been changed…

2024-02-15 18:10:17 UTC

Trying to package Blockstream’s esplora into Nix’s package manager.
Made me figure out that this app doesn’t have a version number. This is despite the fact that the app it’s a fork of has one. Not a good thing for Nix, as it requires immutability. Will have to resort to a commit hash, I guess.
Still wondering which version number Nix will end up displaying to its users… how will they know how up to date they are? Not convinced a hash would do it.
