Pathetic – Java pathfinding: 10k concurrent paths in ~7ms
It started with drones. My co-founder and I were building a Minecraft plugin where drones had to navigate through unloaded chunks - terrain that doesn't even exist in memory yet. No existing library had any concept of it, which led to drones being stuck in non-existence. Sloppy at first, tightly coupled to Minecraft's API, we built our own. But somewhere along the way we realized: the problem wasn't Minecraft. It was how Java pathfinding is built in general - object-heavy, GC-hostile, and single-threaded by assumption. So I split the project. The core became its own thing: pure Java 8+ for…
Pathetic – Java pathfinding: 10k concurrent paths in ~7ms launched on May 5, 2026 with 8 votes, #1,430 of 20,538 launches that month and more than 75% of that year's launches.
What it does
The Java pathfinder that ended the era of “good enough” - bsommerfeld/pathetic
The pathfinding library that's too good for this pathetic world. “I used to use library X… then I tried Pathetic and suddenly my server stopped crying.” — every future user, probably It exists for one simple reason: The rest of the Java pathfinding world collectively shits itself above a few hundred concurrent requests. All demos from a real Paper server. Minecraft is a pathfinding hell — Pathetic just walked in, pissed on Hades' leg, and asked for a lighter. Most libraries need minutes or give up entirely on paths longer than 1000 positions. Pathetic does 20 000 before you finish a single blink. You'refrom github.com

Bedrock – An 8-bit computing system for running programs anywhere2025 · benbridle.com · ▲221Hey everyone, this is my latest project. Bedrock is a lightweight program runtime: programs assemble down to a few kilobytes of bytecode that can run on any computer, console, or handheld. The runtime is tiny, it can be implemented from scratch in a few hours, and the I/O devices for accessing the keyboard, screen, networking, etc. can be added on as needed. I designed Bedrock to make it easier to maintain programs as a solo developer. It's deeply inspired by Uxn and PICO-8, but it makes significant departures from Uxn to provide more capabilities to programs and to be easier to…
BFS, Dijkstra and A* interactive demo made in React2021 · github.com · ▲94Visual explanation of pathfinding algorithms and how a*, Dijkstra and BFS can be seen as the same algorithm with different parameter/data structures used under the hood - npretto/pathfinding
A hash array-mapped trie implementation in C2023 · github.com · ▲171Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…
- DRDontBeEvil.rip: Search, for developers (API, expressions, CLI)2022 · ▲269
I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…
Whirlwind – Async concurrent hashmap for Rust2024 · github.com · ▲140Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…
Visual A* pathfinding and maze generation in Python2024 · github.com · ▲135I was fascinated reading through another recent HN submission about a highly efficient implementation of A* in Lisp, which got me thinking about how I could do something similar in Python. However, these kinds of pathfinding algorithms really need complex terrain/mazes with interesting obstructions to showcase what they can do and how they work. So, I started thinking about how I could generate cool and diverse random "mazes" (they aren't really mazes, but I'm not sure what the best term is). I got a bit carried away thinking of lots of different cool ways to generate these mazes, such…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai
Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
