+## Featureflags?
+
+- Idea: Change the behaviour of an application without rebuilding it
+- Goal: Control rollout, reduce risk, experiment (a/b)
+- At google: A huge number of feature flags (150k+) but that's because people forget to turn them off
+
+## Where does the flag come from
+
+- Lifecycle of a flag: Create, Manage, Deprecate, Delete -> But will it be created frist in code or in the service
+- Classic implementation: Just a if/else that uses a function to get the flag
+- Problem: What if the flag names missmatch between the code and flag ser -> Muliple sources of truth
+- Solution: Require use of auto-generated flag bindings (codegen from the management system) to mitigate typos, etc.
+
+## OpenFeature
+
+- Goal: Vendor agnostic, standardized, open source
+- Basic setup: Register provider (once per app), create a client, use client to get flags
+- CLI: Integrate into management system, keep a local manifest of all flags and generate code (generates the client)
+- Now: Just call the client's method instead of hard-coding feature flag names

 The last day of KubeCon - aka the day everone leaves early.
 But not me and I had no meetings scheduled for this day -> More talks for me and notes for you.
 
-This being my 7th day of the trip and 6th day of non-stop conferences took a bit of a toll on my note taking skills (expect more spelling mistakes)
