Go London User Group XV

Welcome to another Go London User Group. We have a couple of great talks lined up:

CockroachDB: Make Data Easy (Tobias Schottdorf)

CockroachDB aims to bring the best aspects of Google's next generation database Spanner to the rest of the world via open source. Databases should scale horizontally with minimum fuss, survive disasters of all sorts including datacenter outages, and provide the right primitives so that developers can easily build scalable, resilient applications without workarounds that can be deployed to any cloud infrastructure seamlessly.

Near real-time configuration with etcd (Dean Elbaz)

Building a micro-service platform at CrowdSurge, we created a near real-time configuration system using etcd and Go's concurrency model. I will go through the design of the system, The difficulties we've encountered, the tradeoffs we've made, and the tools we built around it.

Lighting talk: Gridmix, Multi-player live audio streaming and mixing (Hraban Luyat)

Gridmix (http://gridmix.fishing/) is a multi-player live audio streaming and mixing service. Multiple visitors roam a 2D world and the sound they perceive is a distance-weighed mix of the sound produced by others. The backend was built with Go, I will elaborate on the design, the pains and the gains of getting this up and running.

Lighting talk 2: Circuit breaker pattern in Go (Jonathan MacDougall)
A short story about implementing the circuit breaker pattern in Go. A lesson in not falling in love with your own code and having the safty net of interfaces. It looks like we have some really good talks tonight so I'll keep it short but I wanted to present a real world case where we see interfaces working well. I'm currently working at Ravelin having recently moved on from Hailo where we had a large microservice platform. This story is from my time at Hailo.

We'll also (probably) have time for some other lightning talks: let us know if you'd like to give one. Thanks to our sponsors CloudFlare for providing food and uSwitch for providing drinks and venue.
