Weird Ruby
Over its long history (31 years and counting) Ruby has accumulated dozens of little known, obscure and somewhat weird features. Some of them are annoying, some of them are fun and a few are actually quite useful. In this session we'll go over some of my favorite weird Ruby features and we'll discuss how to make the best use of them (provided they are any useful, that is). It will be weird and fun, I promise!

Senior Director of Engineering @ Toptal
I’m Bozhidar and I love computers in general and programming in particular. My fanatic devotion to Emacs is known world-wide. I spend a lot of my (free) time on GitHub, contributing to various open-source Ruby, Clojure and Emacs Lisp projects. My most notable open-source projects are RuboCop (a linter/formatter for Ruby) and CIDER (a Clojure interactive development environment for Emacs).
News Crawler via Langchain.RB and Gemini APIs
How can we get an LLM to be updated to today’s news? Gen AI is great at answering questions...from the past. After the LLM was trained, all you can do is RAG. How about crawling the web for latest news with Gemini for multimodal extraction and offering summarization by your favorite topic? It all gets more exciting thanks to Andrei’s langchainrb gem.

Using Ruby on AWS's Lambda
A Hitchhiker's Guide to Ruby on AWS's Lambda. Starting from a real world example, I will show how to develop and deploy ruby code on AWS's Lambda. I will show why we chose ruby for the project and why we decided to move part of the monolith code to microservices keeping ruby as main language. I will also show how to test and deploy the code using rspec, cucumber and serverless for a complete CI/CD cycle.

Lucian Ghinda
Senior Ruby Developer by day, Curator of Short Ruby Newsletter during weekends
I am a Senior Ruby Developer, but I like to describe myself as a 'polymorphic' Ruby developer, as in the past 15 years working with Ruby, I have worn many different hats. I worked as a Senior Ruby Developer, Senior Product Engineer, Product Owner and Engineering Manager, but my not-so-secret passion is the mix of programming, teaching and mentoring. Out of this passion, I ran meetups and bootcamps, co-founded a learning academy, and mentored developers.

From Data to Recommendations: Building an Intelligent System with Ruby on Rails
Did you know that 75% of users are more likely to engage with a platform offering personalized recommendations? Well, with 1.2 million websites worldwide built on Ruby on Rails, let’s harness the power of this popular framework to implement intelligent recommendations effortlessly! This talk will explore the exciting realm of recommendation systems and how to build an intelligent system using Ruby on Rails. We will start by unraveling the fundamentals of recommendation systems, including collaborative filtering. With this foundation, we will integrate machine learning techniques into the Ruby on Rails framework. Throughout the talk, we will discuss various strategies for capturing and utilizing user preferences, improving recommendation accuracy, and continuously refining the system based on user feedback. By the end of this talk, you will have gained valuable insights into building an intelligent system that can transform raw data into valuable recommendations within a Ruby on Rails application!
