Project mention: Show HN: Extend UI – open-source UI kit for modern document apps | news.ycombinator.com | 2026-06-10
Using lopdf[1] for PDF parsing, rtf-parser[2] for RTF, and I'm sure you know that DOCX/PPTX/etc. is basically just a zip file of XML. The LLM cares about textual data (which just gets moderately cleaned up post-extraction), so I didn't have to deal with rendering.

> As an example, I still do not understand why simple HTTP crates require more than 50 to 70 dependencies to execute a simple GET call...
Looking at ureq [0], for example, its direct non-build/non-dev dependencies are (counting duplicates):
- base64
- flate2 (4 transitive dependencies)
- log
- percent-encoding
- rustls (26 transitive dependencies)
- rustls-pki-types (1 transitive dependency)
- ureq-proto (7 transitive dependencies)
- utf-8
- webpki-roots (2 transitive dependencies)
The vast majority of the raw dependency count comes from Rustls and related crates, and I'd imagine reimplementing a TLS stack would be somewhat out of scope for an HTTP crate. I'm not sure there's much room for substantial reductions in dependency count otherwise.

By the way, M$$$ has already making the transition of its driver writing in Rust
https://github.com/microsoft/windows-drivers-rs
maybe this will be good for the rest of the kernels, Illumos/HaikuOs/ReactOs.
