    Hexagonal hierarchical geospatial indexing system

    Project mention: Rendering earth as hexagons using Godot3 & H3 | reddit.com/r/godot | 2021-11-13

    The challenging work is done by Uber's H3 library. https://h3geo.org I would suggest checking out their documentation, which describes things well with pictures. First easiest attempt was to call their APIs to get geo boundaries and use Godot's MeshTool to generate hexagon MeshInstances.

    LiteSpeed QUIC and HTTP/3 Library

    Project mention: LiteSpeed QUIC (LSQUIC) is an open-source implementation of QUIC and HTTP/3 | news.ycombinator.com | 2021-02-15

    > the word "thread" does not appear anywhere.

    because it doesn't use threads? The library is intended to be used inside an eventloop. I think the same also applies for other typical transport libraries - e.g. HTTP/2 or TLS ones.

    > Not sure why one would choose this over QUICHE.

    I think there are certainly reasons. lsquic seems a lot more optimized than quiche and most other libraries out there. It makes use of some pretty clever datastructures (e.g. https://github.com/litespeedtech/lsquic/blob/master/src/libl...), and likely has a drastically lower rate of heap allocations than other implementations. Some of those things - like the use of intrusive linked lists - are unfortunately not that easy to apply in Rust.

    I wouldn't be suprised if lsquic outperforms various other implementations - and if that's important to users it might be a reason to choose it (but as always: measure for your use-case).

    I personally also think Rust is the way to go for system level code. But I wouldn't dismiss a project for not using Rust. And this one at least has a fair set of unit-tests, so it looks to me a lot more sane than a lot of other C based projects.
