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

After #Devoxx Driven Development comes Devoxx Driven Debugging 🤓#DDD
Found a memory leak in the Server-Side Rendering (SSR) function last night for the Devoxx Companion webapp - turns out that’s why the site eventually became unresponsive #Fixed 🪲
