Last Stuttgart Gophers Meetup before Christmas!

Thoughtworks Deutschland GmbH

🤘 Salutations London Gophers!!! 🤘

With Halloween soon to be behind us (the scariest place for it to be) we have Guy Fawkes night to look forward to - and where better to be on the 5th of November than nowhere near parliament?! Happily, the lovely people at NALA (hosting for the first time!) are putting us up for the night at their base in nice, safe Canary Wharf!

==== 📓 **Agenda**📓 =====

**6:30pm:** Arrival, Food & Refreshments
**6:55pm:** Introduction

**7:00pm: 🗣️ Bailey Matthews: Under the Radar: Go Build Flags**

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.

**7:25pm:** Break

**7:45pm: 🗣️ Wisdom Matthew: Distributed Mutex in Go with Redlock**

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.

**8:10pm: 🗣️ Weyert de Boer: OpenFeature: Feature Flags the easy way**

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.

**8:35pm:** Socialising
**9:00pm:** Pub!
