Excited to share that maplibre-gl-lidar v0.6.0 is now available!
This release adds support for the Entwine Point Tile (EPT) format (entwine.io/en/latest/en...), making it possible to stream and visualize billions of LiDAR points directly in the browser with ease and performance.

I've been working a little on Terra Route today and the accompanying drawing mode for Terra Draw. You can use these together to do browser based map routing. I made some performance improvements that I think that even for decent sized areas the route snapping feels instant for the user

Interop is brilliant. Aligning the efforts of all browsers around crucial focus areas every year is doing wonders for interoperability, and its effect is compounding.
Switch to the “experimental” tab (which is not about experimenting, but about what is definitely coming soon) and you can see that every browser reached at least 98. Once all this engineering work ships in browsers, the overall interoperability for these 19 Focus Areas is 96%!

Some friction is healthy in our online interactions. You shouldn't be able to send a bug report without a reproduction. You shouldn't be able to create a PR without understanding the issue (and the solution). You should (try to) be aware of their context before replying to an unknown person online.

Of course, whether I can schlep back and forth across campus in time is a different question 😄

I updated my blog for the first time in a year or so remove the links to Twitter and also to fix some responsive design issues. Now more than ever it feels having some space online that you own and control (as much as is feasibly possible in a cloud first world) is important to maintain.

PSA - don't be one of those people. We need Browser diversity and everyone working on the open Web should be supportive, not destructive!
An absolutely wild and gutting part of this role is having so many people desperate for you to fail. I know I know tiny violin etc etc. Anyway, new video out later today!
