> Engineering for the age of inference. Articles and projects on data platforms, AI systems, and cloud infrastructure by Istvan.

Written by Istvan, Systems Engineer & University Lecturer. Articles explain how AI, data and cloud systems behave in production; projects are open-source Rust tools.

## Articles

- [Does the Sumerian King List Align With Paleoclimate Events?](https://www.vectorian.be/articles/2026-06-07/sumerian-king-list-paleoclimate-alignment-explorer/): A statistical test of whether the Sumerian King List's antediluvian reigns line up with paleoclimate events better than chance.

## Projects

- [harrow: Macro-Free HTTP Framework](https://www.vectorian.be/projects/harrow/): A thin, macro-free HTTP framework over Hyper with built-in observability, runtime-inspectable routing, and sub-microsecond overhead.
- [ro11y: Lightweight Observability](https://www.vectorian.be/projects/ro11y/): Hand-rolled OTLP protobuf over HTTP, built on Rust's tracing crate. Seven dependencies instead of a hundred and twenty.
- [marie-ssg: Static Site Generator](https://www.vectorian.be/projects/marie-ssg/): A fast, single-purpose static site generator that turns markdown and TOML metadata into HTML using Jinja-style templates.
- [qrst: On-Device Hybrid Search](https://www.vectorian.be/projects/qrst/): A single-binary hybrid search engine combining BM25 keyword search with vector semantic search, running entirely on-device.
