Just made my first contribution to a Wikipedia page 😱. Never too late to do this, right? en.wikipedia.org/wiki/Cloud_N... #CNCF #Dapr

Dapr, the distributed application runtime, provides APIs for building secure and reliable microservices and agentic AI systems. Dapr was donated to the CNCF in November 2021 and joined at incubation level. The CNCF announced its graduation in November 2024.

Have you seen the Dapr 1.16 preview docs site? Docs link => v1-16.docs.dapr.io. It's finally upgraded to use the latest Hugo! (it was running on a version from 2022 😬) Upgrading it was quite some work, since the markdown content files also needed to be updated. There are two major wins... 🧵

Sure, gen-AI can do some nice tricks. But please don't upload your personal photos and likes to an AI to create your personal action figure. Be careful of your digital privacy. And use AI moderately since it's trained on data obtained without consent. Here's an image I drew in Aseprite. #pixelart
