Show HN: Chonkie – A Fast, Lightweight Text Chunking Library for RAG (Score: 150+ in 21 hours)
Link: https://readhacker.news/s/6hK2m
Comments: https://readhacker.news/c/6hK2m
I built Chonkie because I was tired of rewriting chunking code for RAG applications. Existing libraries were either too bloated (80MB+) or too basic, with no middle ground.
Core features:
- 21MB default install vs 80-171MB alternatives
- 33x faster token chunking than popular alternatives
- Supports multiple chunking strategies: token, word, sentence, and semantic
- Works with all major tokenizers (transformers, tokenizers, tiktoken)
- Zero external dependencies for basic functionality
Technical optimizations:
- Uses tiktoken with multi-threading for faster tokenization
- Implements aggressive caching and precomputation
- Running mean pooling for efficient semantic chunking
- Modular dependency system (install only what you need)
Benchmarks and code: https://github.com/bhavnicksm/chonkie
Looking for feedback on the architecture and performance optimizations. What other chunking strategies would be useful for RAG applications?

Krita's v4.2+ RGBA brushtips let you paint with dimensionality, and it's a technology that Photoshop doesn't have (≖‿ゝ≖)
It lets the creator do things like emulating light direction, making brushstrokes look 3D.
I used them to make a set of metallic brushes. If there are any FOSS artists around, feel free to test them out.
(p.s. Yes, I am learning Github so I probably made repository mistakes - apologies in advance lol)

Is 3D printing being held back by an invalid patent? (Score: 150+ in 10 hours)
Link: https://readhacker.news/c/6hKtD
Parts made using the FFM (FDM) process are stronger in some directions than in others. This is due to imperfect adhesion between printed layers. This directional or anisotropic structural strength is a significant limiting factor for the structural integrity of 3d printed parts made with the common FFM process.
A method to drastically reduce this effect is described in an expired Stratasys patent, US1997/5653925A. As of this writing, I have not seen this feature implemented in any of the common open-source slicers. I would have expected this now-public-domain knowledge to have made its way into the slicers we use since the patent expired in 2017.
With some investigation, I believe this may be because of the 2023 patent US2023/11813789B2, to my knowledge only implemented as a proprietary in-house product of a 3d printing service house which appears to make the same claims illustrated in the 1997 Stratasys patent.
I am not expertly versed in patent law, but this patent would seem to have been granted in error. The fact that the 2023 patent actually references the Stratasys patent from 1997* makes the issuance of this patent even more baffling. At any rate, this seems like a low-hanging opportunity for a significant improvement in print strength that could benefit millions of users.
*The 2023 patent references the 1997 Stratasys patent as “teaching a process for adjusting the deposition rate .. to provide a predetermined porosity rate” but neglects to mention that the core claim of the patent was the staggered bead heights claimed.
In referencing the 1997 patent the 2023 work also gives a single-digit error in the patent number, as well as other “minor” errors in other patent numbers referenced in the patent. These misleading references could have impeded the examiner’s role in determining the validity of the patent.
