Finding unused Ruby methods #

Joel Biffin says:

Whether code is safe to delete or not is a bit of a murky question in Ruby - especially in untyped Ruby. Fear not though, as dangling unused methods are a pretty safe place to start deleting things. Let's start there and see where we get to. Introducing the Thanatos gem to help you find those unused methods lurking in your code.

Things I've learned maintaining OpenStreetMap #

Andy Allan says:

Maintaining one of the world's largest non-commercial websites, OpenStreetMap, is a unique challenge. We're a small, volunteer-based development team, not professional software developers. I will illustrate some of these challenges with a mixture of technical and organisational tips, tricks and recommendations, that you might find useful for your own teams and projects too.

LiveView: stateful, server-rendered HTML #

Yevhenii Kurtov says:

LiveView is Elixir's analogue to Hotwire that also helps to keep it closer to the server and contributes to the One Person Framework movement. In this talk, we will explore how the stateful model makes it different from similar technologies and what optimisations the Phoenix team did to make it feel snappy and deliver a world-class UX

Build and maintain large Ruby applications #

Enrico Teotti says:

This presentation will be about the challenges of building large Ruby web applications and how to maintain existing ones. I will use examples adapted from real applications that I worked on during my 10 years of experience with Ruby outlining: technical limitations of the language, how to use a modular dependency structure to enforce boundaries in complex domains.

Building modern eCommerce applications using Rails 7 #

Winston Ferguson says:

With the newest Rails version, we can create platforms that offer the modern features customers and sellers expect, with less complexity. Combine it with an established open-source gem like Spree, and you've got a comprehensive commerce system. I'll share my learnings from three real-life examples: a music label selling limited edition vinyl LPs, a wholesaler shedding enterprise SaaS for a tailor-made setup, and my furniture startup, where CAD brings bespoke pieces to life.

WTF is Technical Strategy #

Laurie Young says:

The phrase "Technical Strategy" is often used by senior leaders when they want something from their tech teams. However, it's an unclear phrase that doesn't explain what is needed or why. In this talk, you will learn what's behind the phrase, but also how anyone from a CTO to a new developer can use that knowledge to drive conversations that will help not just the leadership but the whole organisation.

What is ruby really capable of? #

fell sunderland:

I'd like to do a whistlestop tour of a few different gems I've written over the years, with the aim of talking about having fun whilst learning what ruby is capable of. I'd like to showcase things like aspectual for bringing aspect oriented programming to ruby, cherry-pick for when you miss import foo from bar, overload for when you want to really have optional arguments do something different, and more!

Sky Computing #

Kevin Sedgley says:

What comes after cloud computing? Cloud computing is convenient, ubiquitous and relatively cheap. But it also locks developers into proprietary solutions that make migrating to another provider or bringing your solutions back in-house difficult and expensive. If AWS, Google Cloud Computing, Azure and all the others are clouds, then we also need a sky. Researchers at Berkeley and other institutions have proposed sky computing: an interoperability layer that removes technological lock-in and enables multi cloud application development.

Leveraging Localised Gems (LLGems): Re-using Code the Ruby Way, Safely #

Joel Biffin says:

The talk takes a look under the hood of our Rails monolith, our Rails Engines, and how we share code between them. It's a bit like a kitchen experiment – blending the best of both worlds to enhance the Separation of Concerns, while still keeping our favorite code recipes within reach. I'll share our adventure of moving some Kafka infrastructure code from the main Rails app into a local gem (with zero downtime!). Think of it as giving the code a new home where it can be shared across our Rails Engines. We've also managed to preserve our unique, in-house testing infrastructure in the process which is a serious Brucie bonus!
