I was worried we might hit the #Gemini quota for moderating #Devoxx Belgium comments, feedback & transcript insights, but we ended up using only ~90K tokens. The real cost driver (which was expected) was the min instances of the Universal SSR Cloud Function, which I set to 8 🚀

Ever wondered when Devoxxians rate talks? I did too, so I "built" a time-series stacked bar chart in the #Devoxx Companion app for speakers 👀🔥☕️ v0.4.23

Just released v0.4.14 of the #Devoxx Companion! 🎉
This update restores your previous position in the schedule list/grid when you return from viewing a talk.
A small but great #UX improvement.
Big thanks to Frederick for the shout out! 👍🏼☕️

Small critique on the #Devoxx companion app: when you open a talk from the schedule list and go back, it jumps back to the top of the list instead of keeping your place.
