The CNCF project OpenFeature offers a standardised and vendor agnostic way to deal with feature flags in your project. The talk shows how can you use it in your Golang project. If there is time I would like to also talk about the OpenFeature Remote Evaluation Protocol (OFREP) which allows you to use feature flags by implementing an endpoint without needing to any extra code to support your feature flagging system.

Local mutexes synchronise access to data within a single process, but many real-world systems need to coordinate access to shared resources such as databases or queues. This talk examines how the Redlock algorithm, built on Redis, enables Go services to manage concurrency safely and efficiently across multiple instances.

A quick whistle-stop tour through some of the Go build flags you might have missed. We’ll look at how to bundle assets, use build tags for different environments, change variables at build time, and trim down binaries for final deployments.
