Products that do what Tree, truth, druid and tar share one Proto-Indo-European root does
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…

I built this project as a way to learn more about NLP by applying it to something weird and unsolved. The Voynich Manuscript is a 15th-century book written in an unknown script. No one’s been able to translate it, and many think it’s a hoax, a cipher, or a constructed language. I wasn’t trying to decode it — I just wanted to see: does it behave like a structured language? I stripped a handful of common suffix-like endings (aiin, dy, etc.) to isolate what looked like root forms. I know that’s a strong assumption — I call it out directly in the repo — but it helped clarify the clustering. From…

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…

Hi HN, (First time poster!) I'm the author of `lstr`. I've always loved the classic Linux `tree` command for its simplicity, but I often found myself wanting more modern features like interactivity and Git integration. So, I decided to build my own version in Rust with a philosophy of being fast, minimalist, and interactive. It was also an excuse to help learn more about Rust\! Here's a quick look at the interactive mode: https://raw.githubusercontent.com/bgreenwell/lstr/main/asset... I've just released v0.2.0 with some features I think this community might find…

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:…

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…

Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

Hi everyone, I've made an open-source library for fast spatial search in Rust. It's called Spart, and it currently provides the following features: - Five tree implementations: Quadtree, Octree, Kd-tree, R-tree, and R*-tree - Python bindings (`pyspart` on PyPI) - Fast k-nearest neighbor (kNN) and radius search - Bulk data loading for efficient tree construction Project's GitHub repo: https://github.com/habedi/spart

I've created Tree of Knowledge (tree-of-knowledge.org), a dynamic visualization tool that organizes all fields of knowledge into an interactive tree structure (generated by AI). As a Computer Science student, I built this to make exploring and connecting different areas of knowledge more intuitive and engaging. You can satiate your curiosity and grasp anything a click away... fast and easy. Key features: - Start from the green 'Knowledge' node to explore the entire tree - Customize your own Start Node to focus on any specific area (this can be anything!) - Interactive interface for easy…

I'm always looking for easy ways to visualize data from CLI so I built something I couldn't find an existing solution for. a := gree.NewNode("root") a.NewChild("child1") a.NewChild("child2").NewChild("grandchild1") fmt.Println(a.Draw()) Makes root ├── child1 └── child2 └── grandchild1 Curious if others find it useful

Hi HN, I've just made a ruby gem for parsing Mermaid syntax, and it's an extension of kramdown parser. I'd love to get feedbacks and or problems you encounter.

We create minimalistic and secure container base images. All images only contain the relevant package (e.g. python) and its dependencies. We even created our own Linux distro, called MinimOS, to be in control of all packages and build a new version as soon as it is available upstream. As opposed to Alpine Linux we mostly use glibc. Images are re-built daily and we continuously add more of them. By using our base images you can easily reduce the number of vulnerabilities by more than 90% (compared to Docker Hub). You can use our images for free (the 'latest' line) here:…
