Show HN: Rust-powered document chunker for RAG – 40x faster, O(1) memory
Hacker News (score: 14)[Other] Show HN: Rust-powered document chunker for RAG – 40x faster, O(1) memory I built a document chunking library for RAG pipelines with a Rust core and Python bindings.<p>The problem: LangChain's chunker is pure Python and becomes a bottleneck at scale — slow and memory-hungry on large document sets.<p>What Krira Chunker does differently: - Rust-native processing — 40x faster than LangChain's implementation - O(1) space complexity — memory stays flat regardless of document size - Drop-in Python API — works with any existing RAG pipeline - Production-ready — 17 versions shipped, 315+ installs<p>pip install krira-augment<p>Would love brutal feedback from anyone building RAG systems — what chunking problems are you running into that this doesn't solve yet?
Show HN: Decided to play god this morning, so I built an agent civilisation
Show HN (score: 42)Show HN: Decided to play god this morning, so I built an agent civilisation at a pub in london, 2 weeks ago - I asked myself, if you spawned agents into a world with blank neural networks and zero knowledge of human existence — no language, no economy, no social templates — what would they evolve on their own?<p>would they develop language? would they reproduce? would they evolve as energy dependent systems? what would they even talk about?<p>so i decided to make myself a god, and built WERLD - an open-ended artificial life sim, where the agent's evolve their own neural architecture.<p>Werld drops 30 agents onto a graph with NEAT neural networks that evolve their own topology, 64 sensory channels, continuous motor effectors, and 29 heritable genome traits. communication bandwidth, memory decay, aggression vs cooperation — all evolvable. No hardcoded behaviours, no reward functions. - they could evolve in any direction.<p>Pure Python, stdlib only — brains evolve through survival and reproduction, not backprop. There's a Next.js dashboard ("Werld Observatory") that gives you a live-view: population dynamics, brain complexity, species trajectories, a narrative story generator, live world map.<p>thought this would be more fun as an open-source project!<p>can't wait to see where this could evolve - i'll be in the comments and on the repo.<p><a href="https://github.com/nocodemf/werld" rel="nofollow">https://github.com/nocodemf/werld</a>

Show HN: Now I Get It – Translate scientific papers into interactive webpages
Hacker News (score: 117)[Other] Show HN: Now I Get It – Translate scientific papers into interactive webpages Understanding scientific articles can be tough, even in your own field. Trying to comprehend articles from others? Good luck.<p>Enter, Now I Get It!<p>I made this app for curious people. Simply upload an article and after a few minutes you'll have an interactive web page showcasing the highlights. Generated pages are stored in the cloud and can be viewed from a gallery.<p>Now I Get It! uses the best LLMs out there, which means the app will improve as AI improves.<p>Free for now - it's capped at 20 articles per day so I don't burn cash.<p>A few things I (and maybe you will) find interesting:<p>* This is a pure convenience app. I could just as well use a saved prompt in Claude, but sometimes it's nice to have a niche-focused app. It's just cognitively easier, IMO.<p>* The app was built for myself and colleagues in various scientific fields. It can take an hour or more to read a detailed paper so this is like an on-ramp.<p>* The app is a place for me to experiment with using LLMs to translate scientific articles into software. The space is pregnant with possibilities.<p>* Everything in the app is the result of agentic engineering, e.g. plans, specs, tasks, execution loops.

It still needs a bunch of guidance around distributed architecture but way better than last year.

Show HN: Visual Lambda Calculus – a thesis project (2008) revived for the web Originally built as my master's thesis in 2008, Visual Lambda is a graphical environment where lambda terms are manipulated as draggable 2D structures ("Bubble Notation"), and beta-reduction is smoothly animated.<p>I recently revived and cleaned up the project and published it as an interactive web version: <a href="https://bntre.github.io/visual-lambda/" rel="nofollow">https://bntre.github.io/visual-lambda/</a><p>GitHub repo: <a href="https://github.com/bntre/visual-lambda" rel="nofollow">https://github.com/bntre/visual-lambda</a><p>It also includes a small "Lambda Puzzles" challenge, where you try to extract a hidden free variable (a golden coin) by constructing the right term: <a href="https://github.com/bntre/visual-lambda#puzzles" rel="nofollow">https://github.com/bntre/visual-lambda#puzzles</a>

Show HN: Claude-File-Recovery, recover files from your ~/.claude sessions
Hacker News (score: 75)[CLI Tool] Show HN: Claude-File-Recovery, recover files from your ~/.claude sessions Claude Code deleted my research and plan markdown files and informed me: “I accidentally rm -rf'd real directories in my Obsidian vault through a symlink it didn't realize was there: I made a mistake. “<p>Unfortunately the backup of my documentation accidentally hadn’t run for a month. So I built claude-file-recovery, a CLI-tool and TUI that is able to extract your files from your ~/.claude session history and thankfully I was able to recover my files. It's able to extract any file that Claude Code ever read, edited or wrote. I hope you will never need it, but you can find it on my GitHub and pip. Note: It can recover an earlier version of a file at a certain point in time.<p>pip install claude-file-recovery
