24 alternatives to Kentro – a fast Rust library for K-Means clustering

Double-digit speed-ups over naïve K-Means Parallel by default (Rayon) Balanced & spherical variants in one crate Memory-savvy for multi-GB datasets Builder API that just feels ergonomic Docs are live, the license is Apache-2.0, and the repo is one `cargo add kentro` away. Give it a spin—curious to hear how it performs in your pipelines!

Want something better than k-means? Try BanditPAM▲281
Want something better than k-means? I'm happy to announce our SOTA k-medoids algorithm from NeurIPS 2020, BanditPAM, is now publicly available! `pip install banditpam` or `install.packages("banditpam")` and you're good to go! k-means is one of the most widely-used algorithms to cluster data. However, it has several limitations: a) it requires the use of L2 distance for efficient clustering, which also b) restricts the data you're clustering to be vectors, and c) doesn't require the means to be datapoints in the dataset. Unlike in k-means, the k-medoids problem requires cluster centers to be…

Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3▲185
I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…

I quit my job to build a Kubernetes GUI with Rust▲13
About a year ago I was working on a project with mirrored Kubernetes clusters deployed across various regions. Constantly switching contexts was a big pain for me and I badly needed something more practical to work with multiple clusters, ideally simultaneously. At that time everyone was talking about Rust and I really wanted to try it out. I then found Tauri, a framework to build GUI apps with Rust + JavaScript. I was sold. I learned Rust and built the app I always wanted to use. Fast, lightweight and with the ability to connect to multiple clusters simultaneously. Fast forward to today,…

Koreo – A platform engineering toolkit for Kubernetes▲120
A large part of our (Real Kinetic's) business is helping organizations implement platform engineering, but we've found the existing tooling to be lacking. For IaC, Terraform state becomes a pain because TF treats infrastructure as "one-shot" commands. The Kubernetes controller model provides a nicer approach to managing infrastructure, but the tooling here is also lacking. For configuration management, Helm just doesn't really scale with complexity, nor does Kustomize. For resource orchestration, Crossplane is a step in the right direction but still has challenges and limitations. As a…

Rust/WASM lighting data toolkit – parses legacy formats, generates SVGs▲52
Hi HN, I'm Holger, a developer who worked in the lighting industry. I built this to scratch my own itch and put it on crates.io and PyPI where nothing like it existed. The old file formats (EULUMDAT from 1990, IES from 1991) still work fine for basic photometry. But the industry is moving toward spectral data – full wavelength distributions instead of just lumen values. The new standards (TM-33, ATLA-S001) are barely supported by existing tools. So this handles both: legacy formats for compatibility, spectral data for anyone who wants to work with the new standards. Stack: Rust core, then…
