Tree, truth, druid and tar share one Proto-Indo-European root

What it does

In the maker’s words, at launch

Did you know that truth, druid, dryad, tar and dendrite all grew from the same root as the word tree? A single Proto-Indo-European root, *deru-. Source code: https://github.com/stared/tree-of-tree I am grateful to Miroslav Šedivý, a Czechoslovak polyglot I met at PiterPy 2018, who sparked a curiosity that Polish 'zdrowy' (healthy) is from 'drewno' (wood) or 'drzewo' (tree), which are related to the English word 'tree'. A few weeks ago I saw Odd Pride's short on the tree of life, which prompted me to make an explorable explanation (https://p.migdal.pl/blog/2024/05/science-games-explorable-ex...), a medium close to my heart.

  Turn your name into a tree in an infinite procedural shanshui landscapeJun 2026 · landscape.bairui.dev · ▲41

  Hi HN! I made this after collecting hundreds of "name → tree" submissions at ITP. Live: https://landscape.bairui.dev/ Source: https://github.com/pearmini/infinite-landscape Plant a tree: https://tree.bairui.dev/ Pan and zoom an infinite procedural landscape. Each name is converted to ASCII codes, which grow into a unique tree (breadth-first branching; repeated digits become mathematical roses). Mountains use midpoint displacement + Perlin noise, with SVG radial gradients in the blue/green/gold palette from Wang Ximeng's "A Thousand…

  Lingo – A linguistic database in Rust with nanosecond-level performanceSep 2025 · ▲42

  Hi HN, I made Lingo - the SQLite of semantic search. I'm a self-taught developer and researcher who left school at 16, and I've spent some time exploring a first-principles approach to system design for various frontier problems. In this case it's AI that challenges the 'bigger is better' transformer paradigm. Lingo is the first piece of that research, a high-performance linguistic database designed to run on-device. The full technical overview and manifesto is here: https://medium.com/@robm.antunes/bcd1e9752af6 The paper has been archived on Zenodo with a DOI:…

  Nucleus – A security-hardened, Nix-native container runtimeJun 2026 · github.com · ▲40

  Hi HN, I've been building Nucleus, a lightweight Linux container runtime focused on two workloads: ephemeral AI-agent sandboxes and declarative NixOS services. It's a single Rust binary, no daemon. It is not a Docker replacement and not a strict subset of Docker either. I dropped the entire image-and-distribution half (no Dockerfile, no layers, no registry, no pull/push, no persistent storage layer) in exchange for going deeper on isolation and reproducibility. The rootfs is either a directory copied into tmpfs (agent mode) or a Nix-built closure mounted read-only (production mode). If…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
