Hello.

I added ActivityPub support to my static Hugo blog hosted on Vercel. It now automatically announces new posts to followers on the Fediverse. Key challenges included implementing the ActivityPub protocol for a static site, handling WebFinger discovery, managing Follow/Unfollow requests, and sending signed HTTP requests. I used Vercel Serverless Functions for dynamic request handling and Firebase Firestore for storing follower data. Check out the code and follow me @paul@paul.kinlan.me to see it in action!

Back in February, I presented at TwitterDevNest about getting data in and out of Buzz. The slides are now available on SlideShare. I covered WebFinger, OpenID, Buzz feeds, Pubsubhubbub, and Salmon. I also promised to open-source the demo code, which I'll be pushing to Github later today (covering most of the topics except Salmon).
