No no, not country flags, feature flags! Feature flags are a powerful technique that allows teams to modify a system's behaviour without changing code. They can be used several reasons - canary releases and A/B testing to name a few.

This talk will show you how you're already using feature flags in your application without realising it. Next, we'll take a look at some of the best tooling out there to help you take feature flags to the next level. Finally, we'll cover strategies for removing feature flags before they become technical debt that you have to manage.

This is absolutely among my favorite talks from the conference. Both fun and to the point. He explained what feature flags are, what kinds are there and how to implement them in our apps. I was worried from the title that the Big Bang Theory references might be too distracting but all the Sheldon pictures and references worked absolutely fine.

Great talk, informative, on point.

Michael gave a nice talk introducing and explaining what feature flags are and how and when to use them.

Although Michael is a native English speaker, his accent and pronunciation are, at times, a bit overwhelming and presented a distraction for me.
