So why would anyone want to put alot of data into a browser? Well, for a lot of the same reasons that edge computing and distributed computing have become so popular. You get the data a lot closer to...

As promised, here's the notebook (thanks @observablehq!). The new functions are a little esoteric, but they open up some very efficient data processing approaches - let me know what you do with them!
observablehq.com
The 4.1.0 release of the H3 library added two new functions, `cellToChildPos` and `childPosToCell`. These functions are a little less obvious than others in the H3 library, but they open up some...

h3-js v4.1.0 is now up on npm 🎉 https://t.co/24LuZsBVma This version fixes the bundle for React Native and Web Workers, and includes the new functions cellToChildPos and childPosToCell - I'll put up a new notebook soon to demo some of the new use cases they support.

Just to reiterate the release notes: H3 v4 does not change the cell indexes themselves. It's 100% compatible with existing data, using the same hexagons you know and love ⬣❤️⬣❤️⬣

For h3-js users, npm/yarn should protect you from breaking changes until you're ready to upgrade. But if you use an *unpinned* version of h3-js, e.g. in @observablehq notebooks, you'll want to pin the import to 3.7.2 to avoid errors.

H3 v4 is a major version update with a number of breaking changes - notably, we've renamed a number of functions for clarity and consistency, addressing a big user pain point. You can see the upgrade guide here:

Over the weekend, we published the first v4 release candidate for h3-js 🎉. We've been working on v4 of the core H3 library for some time, and we're excited to get it out to users.

[4.0.0-rc1] - 2022-07-28 First release candidate for H3 v4 🎉 . As noted below, most function names have changed, but the H3 indexes have not, so while using v4 will require code changes it should...

Always great to see #H3 used in a new project - this is super interesting, and really well done!
Finally, the only daily, global, free map of GPS interference has officially launched: https://t.co/4ezvY3PEQN Watch jamming around conflict zones develop over time. Wonder who's jamming GPS all around Moscow. Like all the best maps, it raises more questions than it answers!

OSM features have landed in @unfoldedinc as Hex Tiles: you can now bring in being on a road or building into your analytics. Or, my favorite, explore the global railroad network: https://t.co/l83qq5YRHg
