Speaker: Kang Sheng Tay, Software Engineer at Shopify
Topic: Behind The Gems 4 :: 6
***
We are inviting makers from the Ruby community to share with us their journey and what they have built. For this month, Kang Sheng will be sharing some of his learnings when building YetAnotherYear. YetAnotherYear is a New Year's Resolutions app that literally lets you keep track of your new year's resolutions. In this talk, he will be focusing on his learnings trying to build a fully functional SPA on Rails. Rails cookie auth for your SPA? Serve assets with Rails to be used in SPA? Managing OAuth using Rails for SPA? Yes, Rails can still do most of the heavy lifting so that he can just manage 1 Heroku instance 🤷‍♂️

Name: Sagar Sonwane (Software Engineer, Josh Software)
Topic: Protobuf & gRPC : Because Milliseconds Matter

Most of the existing microservices are using REST with JSON payloads as a standard way of communicating with one another. But as the number of microservices increases in the infrastructure, the service graph becomes more complex, and as a result, there are pain points and limitations in using REST for communications. Sagar will show you how to use gRPC and Protobuf to overcome these limitations.

Names: Dian Bakti (Software Developer, Acronis)
Topic: Avoiding Gotchas in Go Runtime Behaviors

Go is often perceived as a simple language, but there still could be “interesting” behaviors in this language (ranging from how the language is designed to Go runtime behaviors itself)

Here we want to share interesting stuff we found from Go, some are from real life experiences (read: bugs), some are encountered while digging through documentations, GitHub issues or tech talks by others.

The hope is we could avoid doing the same mistakes in the future, share some good practices with each other, or simply just to appreciate the design behind the language.

Dian is a Senior Software Developer in Acronis Search Engines team.
