Qwen 3.5 probably not good for coding vs Codex and Claude, but could be interesting for local feed curation

hashtree.cc frontend is svelte. Hashtree lib is available in typescript and rust.

As long as the blossom server keeps it, or someone who has viewed it keeps hashtree.cc open and seeds over webrtc

On https://video.iris.to/ (source code in the hashtree repo iris-files package) I have a service worker that handles http range requests to /htree/nhash... and the browser video player can request only the relevant part of the file from the hashtree.

Usually equally sized leaf nodes, but that's not enforced. Actually I made a video-chunker which makes the first chunk 256kb so it starts faster, while the rest are 2MB. Bittorrent v2 compatible 16kb would have been nice, but it's too much overhead for blossom servers.

nhash is a blossom hash of a video file's merkle root + decryption key. /video.mp4 is a filename hint. It's viewable on Iris or https://files.iris.to/#/nhash19j2003959cltp77c7dnlwrfwawqgleju7ethswdsr3q8e8y0xj5qyh4lf9/video.mp4

512gb unified memory Mac ultras are interesting, but might wait for M5. Local LLM would be definitely good, there's so many parts in the remote LLM supply chain that can break.

Hashtree is very simple, it's just blossom + "this is how you define directories and chunk files". Merkle roots are saved in nostr events so you can have npub/path directories whose content you can edit. Files.iris.to supports nip-34 pull requests and issues. You could use it as one remote even if you also use grasp.

They have no url that can be viewed in other apps, this comes from chunked & encrypted blossom-like hashtree-ts https://files.iris.to/#/npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/hashtree-ts

Yes, you can press the "fork" button in files.iris.to to make a public version of your secret repo

Sha256 would be nice, but this is just a git remote helper. Choice of hash algorithm depends on how you init your git repo: git init --object-format=sha256. It stores the .git dir structure (with sha1 blob filenames by default) on blossom.

Need help testing git on blossom:
---
Install rust:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Install git-remote-htree:
cargo install git-remote-htree
Add htree remote to your repo & push
git remote add htree htree://self/your-repo-name
git push htree master
Try cloning a repo:
git clone htree://npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/hashtree-rs
Web interface for browsing repos:
https://files.iris.to/#/npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/hashtree-rs

Added support for encrypted repos:
git remote add htree-secret htree://self/your-secret-repo#link-visible
It replaces #link-visible with #k=randomkey xor key which is required to read the repo.
Encrypted to your nsec only
git remote add htree-secret htree://self/your-secret-repo#private

https://github.com/mmalmi/hashtree-ts - it's basically blossom with directories and file chunking.
* Merkle tree roots published on nostr, so you can have npub/path addressed directories whose content you can update.
* Chunks are encrypted by default (Freenet style CHK content hash key encryption).
* Peers request chunks over WebRTC with Freenet style privacy preserving HTL hops-to-live algorihtm.
* HTTP blossom servers used as fallback.
I also have github replacement on hashtree in the works: https://files.iris.to/#/npub1g53mukxnjkcmr94fhryzkqutdz2ukq4ks0gvy5af25rgmwsl4ngq43drvk/repos/hashtree-ts

Yes, it's sharing with peers over webrtc. cdn.iris.to http as backup for the content addressed chunks

Mister X, Richard Stanley, passed away recently, at 82. He was a British movie director and music producer who moved to Finland in 1970s. I had the honor of meeting him a few times.
He kindly edited my web of trust article "Learning to Trust Strangers" in 2015. https://mmalmi.github.io/learning-to-trust-strangers
Charismatic, fun and friendly, he was one of those people you'll never forget. He lives in our memories and watches over us from the clouds like Mufasa.
Here's a remake of a Hurriganes song written by Stanley in 1970s. The lyrics were too difficult for Finns so he had to sing:

Just sent a new version for review which should fix this by auto-adding the mint of the npub.cash token. In the meantime you should be able to fix this by manually adding the Minibits mint (doesn’t display in the mint list while balance is 0, new version also fixes this).
