July 2026 update for the atproto implementations tables. ➡️ github.com/threddyrex/atproto-links I refreshed the PDS and AppView data, and added a new table for Relays. There are 23 PDSs, 4 AppViews, and 5 Relays.

Welcome to the new atproto.com - AT Protocol
We've updated just about everything about atproto.com to make it easier for developers to just build things.
The week-end is over so I'm pressing ⏸️ on my custom PDS project for now. Here's part 2 of my dev journal. I've learned a lot already and so far I feel like it might actually be worth finishing. It's really cool to get a more intimate understanding of ATProtocol and it's implementation.
How to Make a PDS - Part 2 - Zicklag's Leaflets
zicklag.leaflet.pubOh this is interesting. At first I thought it was yet another lexicon to wrap data on, but it's a way for anyone to use ATProto as a discovery mechanism for their non-PDS-hosted datasets. I hadn't thought of the ATmosphere and the relays as a way to surface arbitrary existing data until know.

🪩 Introducing matadisco.org! — a way to discover open datasets via #atproto that doesn't depend on any single institution staying online. 🕺🏼 We have more public data than ever (satellite imagery, climate models, genomic sequences), but finding it is still painfully hard.
