Wow..
"This BIP describes Formosa, an expansion of BIP-0039 for the generation of deterministic wallets. Where BIP-0039 maps each 11 bits of entropy to one word drawn from a single 2048-word list, Formosa maps each 33 bits of entropy to a short themed sentence built from several smaller, syntactically-typed wordlists. The sentences carry grammatical structure and semantic coherence, substantially improving memorability while retaining all cryptographic properties of the original scheme."

No apology needed. I'd rather you say "no" than to ship something you know is not going to work.

Hmm... yeah, pretty hard to disagree :)

I'm testing mining with Ocean, using hashrate from Braiins, on NixOS.

You can do this too, though admittedly you should consider the set up as a weekend project. The parts specific to NixOS can be found here: https://github.com/emmanuelrosa/btc-clients-nix/tree/master/modules/datum_gateway

Can you guess what I'm cooking up on NixOS? https://image.nostr.build/db55c0233e9ab6819bcc6dae6e82eb34e1c91e635f1abea8ddc461d88da9b048.png

- DATUM Gateway package for NixOS. Check.
- DATUM Gateway NixOS module. Check.
- TCP tunnel to feed my node with hashrate. Getting there.

Not quite. The alternative would be more like a never-ending feeling of shame. Far more toxic than being bored.

Isn't that the truth. And it's as exhausting as it sounds.

And the reason it doesn't look like this, is because the "Bitcoin" Conference is actually a shitcoin conference.

One issue I have with local LLMs (using llama.cpp) is that I run out of vRAM for the context. Once that happens the conversation ends. I have to start a new conversation with an empty context to continue. I haven't found a way to automatically dump some of the older context to make room so I can continue with at least some of the context.

The patched versions of Nix are already merged in the Nixpkgs master branch. But... it comes from staging, so it brings other changes along too.

One busy day in a classroom, I was stressing out about all the things I needed to get done. Check workbooks, plan lessons, etc. While I was running around, checking in with students, one of them raised her hand. So I went to her to see what the problem was. There was no problem. She simply wanted to show me that she could expertly balance a pencil on her nose.

Perhaps I'm weird, but I'm just not interested in coding with an LLM. I use an LLM to research on how to do things, and sometimes to generate example code. But, ... I like coding. Meaning, actually writing the code, not having someone or something else do it for me.

As a practice app, I created an open-source web-based (super) minimalist audio player using Flutter. Obviously I'm biased, but whatever. I'm damn proud of it:
blob:https://github.com/d322391d-b21e-47cd-a208-ad34f5d0cd42
I've tested it natively on Linux and on the web both on Linux and Android. The only quirk I've noticed is that pause/resume doesn't work properly on web.
I'm curious whether it works on iOS. If you'd like to take a look, see https://github.com/emmanuelrosa/tiny_audio_player
There's a link there to try it online.
