I'm designing a custom sticker for my letterbox and I just finished the first character! Who also watched this when they were young? I'll also draw his black and white cat and his red van. #pixelart

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... 🧵

I had so much fun making and testing this game! 😎 I'll be using this after the summer at some conferences where Diagrid will be sponsoring. See you later this year!

My secret ingredient for smooth demos and presentations! 😉

(It's actually a VSCode extension called DemoTime by @eliostruyf.com: marketplace.visualstudio.com/items?itemNa...)

It's video editing time today! I've recorded several #Dapr end-user interviews over the last few months, and today I'm editing them in DaVinci Resolve 🎞️. They'll soon appear on the Dapr YouTube channel! 🎥

Exploring a creative coding sketch that I can use during live performances. The sketch represents a 16 step sequencer in a 4x4 grid and is interactive based on mouse position and key strokes. #p5js #CreativeCoding

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
