Show HN: Tattoy – a text-based terminal compositor (Score: 150+ in 11 hours)
Link: https://readhacker.news/s/6w6hw
Comments: https://readhacker.news/c/6w6hw
Whereas this is mostly a terminal eye-candy project to get you street cred, it does have some serious aspects.
Firstly it solves the age-old problem of low-contrast text, like when you `ls` a broken symlink and the red background colour is too near your current theme's foreground colour. Tattoy solves this by using none other than the web's WCAG 2.1 contrast algorithm for accessible text.
Secondly, an explicit design goal is that Tattoy should be able to polyfill new terminal protocols, the `xwayland` of the TTY if you will. Say if we want to experiment with completely deprecating ANSI codes, then any application that uses a new protocol can be run in Tattoy which itself runs in any ANSI-standard terminal emulator as normal. You can read more about this idea here: https://tattoy.sh/news/an-end-to-terminal-ansi-codes/
But ultimately this has been something more akin to an art project, something to enjoy for the sheer aesthetic pleasure.

Show HN: I recreated 90s Mode X demoscene effects in JavaScript and Canvas (Score: 152+ in 10 hours)
Link: https://readhacker.news/s/6weU5
Comments: https://readhacker.news/c/6weU5
After 25 years of writing software, I was feeling nostalgic for the kinds of things that got me into programming in the first place: the old DOS demoscene. I spent a weekend seeing if I could recapture some of that INT 13H VGA magic using today's web tech, but with the old-school constraints of doing it from scratch.
The result is this portfolio of ten classic effects running in a single HTML file. It's all vanilla JavaScript writing to a <canvas> element, with no external libraries. It was a fun challenge to implement things like:
* The color palette cycling and smooth fading in the Plasma demo.
* The buffer-averaging algorithm for the Fire effect to make the flames feel more natural.
* The distance-based texture crossfading in the Tunnel to create the illusion of flying through different sections.
* A 2D scalar field for the Metaballs to calculate the surface normals for that classic blended, metallic look (I did the best I could with the given constraints).
It was a great exercise in getting back to first principles and a reminder of how much those early demo programmers could accomplish with so little. I hope it brings back some good memories for others who grew up with this stuff.
I'd love to hear about your favorite classic demos or if there are any other iconic effects you think would be a fun challenge to add.
Cheers!

Launch HN: Chonkie (YC X25) – Open-Source Library for Advanced Chunking (❄️ Score: 150+ in 5 days)
Link: https://readhacker.news/c/6vQEL
Hey HN! We're Shreyash and Bhavnick. We're building Chonkie (https://chonkie.ai), an open-source library for chunking and embedding data.
Python: https://github.com/chonkie-inc/chonkie
TypeScript: https://github.com/chonkie-inc/chonkie-ts
Here's a video showing our code chunker: https://youtu.be/Xclkh6bU1P0.
Bhavnick and I have been building personal projects with LLMs for a few years. For much of this time, we found ourselves writing our own chunking logic to support RAG applications. We often hesitated to use existing libraries because they either had only basic features or felt too bloated (some are 80MB+).
We built Chonkie to be lightweight, fast, extensible, and easy. The space is evolving rapidly, and we wanted Chonkie to be able to quickly support the newest strategies. We currently support: Token Chunking, Sentence Chunking, Recursive Chunking, Semantic Chunking, plus:
- Semantic Double Pass Chunking: Chunks text semantically first, then merges closely related chunks.
- Code Chunking: Chunks code files by creating an AST and finding ideal split points.
- Late Chunking: Based on the paper (https://arxiv.org/abs/2409.04701), where chunk embeddings are derived from embedding a longer document.
- Slumber Chunking: Based on the "Lumber Chunking" paper (https://arxiv.org/abs/2406.17526). It uses recursive chunking, then an LLM verifies split points, aiming for high-quality chunks with reduced token usage and LLM costs.
You can see how Chonkie compares to LangChain and LlamaIndex in our benchmarks: https://github.com/chonkie-inc/chonkie/blob/main/BENCHMARKS....
Some technical details about the Chonkie package: - ~15MB default install vs. ~80-170MB for some alternatives. - Up to 33x faster token chunking compared to LangChain and LlamaIndex in our tests. - Works with major tokenizers (transformers, tokenizers, tiktoken). - Zero external dependencies for basic functionality. - Implements aggressive caching and precomputation. - Uses running mean pooling for efficient semantic chunking. - Modular dependency system (install only what you need).
In addition to chunking, Chonkie also provides an easy way to create embeddings. For supported providers (SentenceTransformer, Model2Vec, OpenAI), you just specify the model name as a string. You can also create custom embedding handlers for other providers.
RAG is still the most common use case currently. However, Chonkie makes chunks that are optimized for creating high quality embeddings and vector retrieval, so it is not really tied to the "generation" part of RAG. In fact, We're seeing more and more people use Chonkie for implementing semantic search and/or setting context for agents.
We are currently focused on building integrations to simplify the retrieval process. We've created "handshakes" – thin functions that interact with vector DBs like pgVector, Chroma, TurboPuffer, and Qdrant, allowing you to interact with storage easily. If there's an integration you'd like to see (vector DB or otherwise), please let us know.
We also offer hosted and on-premise versions with OCR, extra metadata, all embedding providers, and managed vector databases for teams that want a fully managed pipeline. If you're interested, reach out at shreyash@chonkie.ai or book a demo: https://cal.com/shreyashn/chonkie-demo.
We're eager to hear your feedback and comments! Thanks!
