Ask HN: Is there prior art for this rich text data model? 2 by chrisecker | 1 comments on Hacker News. I've built a rich text data model for a desktop word processor in Python, based on a persistent balanced n-ary tree with cached weights for O(log n) index translation. The document model uses only four element types: Text, Container, Single, and Group — where Group is purely structural (for balancing) and has no semantic meaning in the document. Individual elements are immutable; insert and takeout return new trees rather than mutating the old one. This guarantees that old indices remain valid as long as the old tree exists. I'm aware of Ropes, Finger Trees, and ProseMirror's flat index model. Is there prior art I should know about — specifically for rich text document models with these properties?

Enabling Media Router by default undermines Brave's privacy claims 2 by noguff | 0 comments on Hacker News. So, Brave now enables Casting by default on desktop — and does so silently, without explicit notification or consent after an update? What fresh hell is this? A browser that markets itself as privacy‑first should not be turning on a network discovery feature by default as if it were a trivial setting. If the Brave team’s operational goal is to expand the browser’s attack surface (more than they already have) they’ve made a strong start. Forcing users to manually opt out of Media Router to protect their systems and data directly contradicts the principle of “privacy by default.” This is exactly the kind of behavior many users left Chrome to avoid. Media Router is not a harmless convenience toggle. Under the hood, it relies on automatic device discovery protocols such as SSDP and UPnP on the local network. That means the browser is actively participating in multicast discove...

Ask HN: How do you cope with the broken rythm of agentic coding? 6 by pauletienney | 2 comments on Hacker News. I used to seek focus and concentration while coding. It was not always easy to reach this flow state but I knew it was possible. I am now using agentic coding quite a lot. The honeymoon is finishing and I am starting to dislike some facets of it. I think the main setback is the rythm. Writing some specs/prompts, launching the agent, confirming quite atomic actions and waiting 10 to 30 seconds until the next question/confirmation. Those very small wait times do not let me reach a concentration state. I feel I am hovering the code. I am not deep into it as I used to be. Do you feel the same? Did you find a way to change this?

Looking for Partner to Build Agent Memory (Zig/Erlang) 2 by kendallgclark | 0 comments on Hacker News. I’m working on a purpose-built memory platform for autonomous AI agents. Right now, agent memory is stuck between two hohum options: RAG (which loses relational topology) and Graph Databases (which require massive pointer chasing and degrade under heavy recursive reasoning). I'm building an alternative using Vector Symbolic Architecture (Hyperdimensional Computing). By mathematically binding facts, sequences, and trees into fixed-size high-dimensional vectors (D=16,384), we can compress complex graph traversals into O(1) constant-time SIMD operations…and do some quasi brain-like stuff cheaply, that is, without GPUs and LLMs. The design is maturing nicely and strictly bifurcated to respect mechanical sympathy: • The Data Plane (Zig): Pure bare-metal math. 2GB memory-mapped NVMe tiles via io_uring. Facts are superposed into lock-free 8-bit accumulators strictly aligned to 64-byte...
