Getting Started with MapLibre GL JS
It originated as an open-source fork of Mapbox-gl-js before they switched to a non-open-source license on 8th December 2020.

75% of Nova Scotia's population lives in the red areas
Do you have programming skills? MapboxGL JS is a great library for stuff like this, you can really easily add a layer of GeoJSON data to a map. If you're looking for something less technical Google map lets you create custom maps where you can add a bunch of pins.

Experimenting with Mapbox GL JS's upcoming globe projection
From the latest commits (not released/stable yet): git clone https://github.com/mapbox/mapbox-gl-js.git yarn install yarn run build-prod-min yarn run build-css Then use the generated mapbox-gl.js and mapbox-gl.css files. See CONTRIBUTING.md for more details.

Reimagining projections for the interactive maps era
> too bad it doesn't come with some code
Mapbox changed the license of their code last year I think to a proprietary one. https://github.com/mapbox/mapbox-gl-js/blob/main/LICENSE.txt
It requires a mapbox user license with billing enabled to use this code, let alone make modifications. But the source is viewable on github.

MapLibre GL is a free and open-source fork of mapbox-gl-JS
The software stopped being open source from v2 onwards. The new licence makes it merely shared source.
This GitHub issue where this change is announced provides a number of more in-depth explanations why this is a bad thing for most users of the software: https://github.com/mapbox/mapbox-gl-js/issues/10162

Ask HN: What Are You Working On?
It's a bummer mapbox isn't open source anymore, now you're (and lots of other peoplare) are stuck pre-2.0.0 :(

A population density map of the state of Pennsylvania
It looks like the base Kontur dataset uses H3 resolution 8, and there’s a lookup table here. “400m” seems to refer to the edge length (which averages to 461m).

[ANN] HexTree: geographical region-to-value mapping
I can speak to quadtrees, but the primary reason for using this is that you need a geographic "dictionary" (not using the word map to avoid confusion with charts), and you're perhaps already using the H3 hexagonal grid system.

What's everyone working on this week (34/2022)?
HexSet: is a way of storing a set of H3 cells in a tree, and doing fast (2-20 ns on my 2013 trashcan Mac Pro) membership tests. You must first convert the input data (e.g. GeoJSoN polygon) into H3 cells.

Surprising result while transpiling C to Go
> What an amazing tool that can completely change function names when it converts from C to Go.
How can one read the code of the benchmark, then switch into virulent sarcasm mode without trying to understand the code? And seeing "+1" comments without any effort to understand is also disheartening.
The blog post had a link about the Go helper functions the author used. It lands on https://github.com/akhenakh/goh3/blob/main/h3.go This shows that the `FromGeo()` function used by the Go benchmark is a helper that calls transpiled functions. The benchmark code itself was of course not transpiled, so the sarcasm was unneeded and wrong.
If anyone wants to dig in deeper, the C function `latLngToCell()` calls 2 functions, see https://github.com/uber/h3/blob/master/src/h3lib/lib/h3Index...

Anyone doing geospatial queries? NoSQL? Amazon Location Service?
Uber just released their library to perform geospatial indexing - https://h3geo.org/. This might be an useful building block for you.
