Show HN: Interactive Tree of Life https://ift.tt/ZuimvYV

Show HN: Interactive Tree of Life Ptree consolidates of 11 taxonomic trees, both categorical like we used in school (plant, animalia) and phylogenetic (evolutionary descent), with instant crosswalk between them. Across those trees it overlays 41 visual properties (categorical and numerical) assembled from hundreds of biological traits and sources. Color the tree by habitat, nutrition, size, longevity, even see vertical range of birds and depth of fish visually. The backend is 800 GB of raw data distilled through a 9-step build process that reconciles and links all 11 trees along with hundreds of traits so every node in every tree gets all the properties. Every color and number presented retains and shows its provenance: original wording, citation, and license. The frontend uses a custom Miller column implementation with fold-away gutter, all composited animation (no frameworks, pure DOM mutation). Use +'s to try to confuse it by expanding many branches and it will fold them away and route edges around them. Made by the creator of ptable.com, a popular interactive periodic table website around since 1997. https://ptree.org/ September 4, 2026 at 04:40AM

Show HN: Gote – a CLI note-taking management tool for plain Markdown https://ift.tt/x7DEMf2

Show HN: Gote – a CLI note-taking management tool for plain Markdown Repo: https://ift.tt/OtN9bGF I built a note taking management tool to use at work for quick note taking and searching. It is intended to be quite minimal. Another focus was to have lots of shortcuts and to keep things close to the homerow for ergonomics and speed. Notes are just markdown files in whatever directory you point it at. The only thing it keeps elsewhere is an index in ~/.gote. If you stop using it you still have all your notes. Tags go on the first line of the note, separated by periods, like .project.urgent.work. No frontmatter. Search is built into the binary, BM25 with stemming, so there's no ripgrep or fzf to set up. gote s meeting searches titles and content, gote s -t .work filters by tag, gote s -w 2412 pulls up notes from December 2024. Most commands have a two letter version that combines a list with an action. ro is recent + open, sv is search + view, tp is tag + pin. When results come up you pick one with a home row key instead of arrows or numbers. Binaries for mac/linux/windows are on the releases page, or go install github.com/banorton/gote@latest if you have Go. The goal of this project was not to learn something new or build something impressive. I simply had a need and filled it with a vibe-coded solution. I have been using it for about a year now and it does more or less exactly what I wanted. So I thought I'd share in case others are interested in using it, contributing to it, or want to use it as a reference for their own solution. September 7, 2026 at 08:55PM

Show HN: HexBOTs – a cellular automaton with robotic lawnmowers https://ift.tt/m6kUSER

Show HN: HexBOTs – a cellular automaton with robotic lawnmowers Double-click or press N to start a new experiment. I built hexBOTs, an unusual cellular automaton based on deterministic robots. The robots behave a bit like robotic lawnmowers, moving through their environment and reacting according to their individual rules. The robots themselves are fully deterministic — no random functions are used while they are running. What makes them different is their “genetics”: each robot's behavior is defined by a randomly generated genome, which allows for an enormous number of different robot types. Randomness creates the robots, but it doesn't drive them. Once an experiment starts, everything follows deterministically from the generated genomes and the initial state. What fascinates me is the complexity that emerges from these relatively simple machines interacting with each other and their environment. Controls: B — enable/disable robots (also: hold mouse/finger down) R — restart N — new experiment (also: mouse/finger double-click) D — save as picture I — show information / controls https://hexbot-genesis.netlify.app/ September 6, 2026 at 11:56PM

Show HN: Cowbull – Wordle-like game where you only get match counts https://ift.tt/3f6Oz7i

Show HN: Cowbull – Wordle-like game where you only get match counts CowBull is a word game where you have to find the hidden four-letter word. You make guesses and get back the count of exact letter matches (bulls) and partial matches (cows). It’s a bit like Wordle, but you are not told the exact letters which match, only the count of matching letters. Scoring is based on the number of guesses and time used. There is a single player mode and a multi-player mode (no account required). The game source code is at https://ift.tt/C5Y8UIb . When I was younger, we used to play this game on paper at the back of the classroom during school and college in India. During Covid, I made this online version of the game to play with my kids. https://cowbull.co/ September 6, 2026 at 04:37AM

Show HN: I made Blocknado, an orbital stacker. Think Tetris with square rings I've loved stacker type games for as long as I can remember. But I've always wanted a version with a bit more strategy and puzzle dynamics. Blocknado is a game I've always wanted to play, maybe others will too. https://ift.tt/RzdwMtc September 6, 2026 at 04:16AM
