This document provides an overview of JRuby, highlighting both advantages and disadvantages compared to Ruby implementations. Key points include:
- JRuby runs Ruby code on the Java Virtual Machine (JVM), allowing access to Java libraries and tools while retaining Ruby syntax and semantics.
- The memory footprint of JRuby applications is initially larger than CRuby due to object sizes, but memory usage over time can be smaller with JRuby's garbage collection.
- Features like fork, continuations, and some extensions may be missing or disabled in JRuby.
- JRuby provides multiple Ruby versions and allows running multiple Ruby applications in a single JVM process.
- Performance benchmarks show JRuby can be competitive with

JRuby is Ruby for the JVM, right? But what does that really mean? What do you get out of the deal?
We'll explore what makes JRuby unique among Ruby implementations, and why the JVM is a Rubyist's dream come true. Using JRuby means you have the best GC, real threads, easy and scalable deployment, high performance, no-compile cross-platform libraries, and the best monitoring and profiling tools of any VM. And you get it all without leaving Ruby behind. If you're not using JRuby already, this talk will convince you to give it a try.

JRuby on Rails - RoR's Simplicity Meets Java's Class (a case in point)Darshan Karandikar
Slides from my talk at RubyConf India 2012. This is a case in point for a highly productive & scalable enterprise application development platform with JRuby on Rails.
When we started to architect an enterprise micro-blogging solution as part of the internal collaboration platform for a large customer (henceforth referred by dummy name 'CustCollab'), the next immediate question was “Which web application development framework to use?”. Simplicity, productivity, ability to deliver high quality of service (QoS), especially performance & scalability, & alignment with CustCollab's technology stack were our top criteria for framework selection. After considerable research on state-of-the-art, we zeroed in on 2 frameworks – 1) “Ruby on Rails” (RoR) for its super simplicity & productivity & 2) “Java Enterprise Edition” (JEE) for its obvious “enterprise” class, high QoS & greater alignment with CustCollab's technology stack. But we just couldn't rule out either one, since each framework had been proven to deliver qualities not so proven in the other framework. Naturally, we started dreaming of a framework which can deliver best of both worlds! And in reality, there lived such a framework – 'JRuby on Rails'!
In this talk I will focus more on our experience of how JRuby, & hence JRoR, has done a fantastic job of delivering best of RoR & JEE worlds to an enterprise application w.r.t multiple 'quality of service' attributes like scalability (parallel processing, Garbage Collection, compilation, caching, advanced database connection pooling etc.), productivity, extensibility, security (especially CSRF), session management, reusability, total cost of ownership (alignment with existing/preferred technology stack) etc.
With the help of the real world 'CustCollab Micro-blogging' case in point, this presentation demonstrates how the distant, isolated worlds of RoR & JEE can synergize with the help of the JRuby bridge to result in a highly productive & scalable enterprise application development platform.
I hope it encourages others to adapt JRuby, & hence Ruby, in the enterprise. After all, as promised by the JRuby dev. team, the JRuby improvisation is well capable of delivering the best of both Java & Ruby worlds, & hence deserves greater attention in the enterprise world!
We all know that load testing is important, but it's all too common that it's left to the very end of a project and it's invariably the first thing that gets dropped when budgets and timeframes get cut. Furthermore, most of us don't know where or how to start implementing effective load tests, let alone how to analyse the results.
Lindsay Holmwood, Software Manager at Bulletproof Networks, will be talking about integrating performance testing into your application development + deploy cycle from the very beginning, using inexpensive and easy to use SaaS tools.
There will be a hands on demonstration of the Blitz load + performance testing tool, coupled with a brief dive into the Blitz API internals to retrieve and analyse advanced reporting information.
This talk provides a number of step-by-step examples that illustrate different ways in which Rails applications can interact effectively with third-party Java libraries. The presentation shows how developers can leverage JRuby to augment Rails applications with the mature, third-party libraries that are widely available in the Java world.

Presenter: Danish Khan
Presentation from: RubyConf Uruguay
Date: November 12, 2011
Description:
Most developers hate having to write documentation, yet complain about how tools and libraries we use lack documentation. How do you get developers to write good documentation without feeling like they're wasting their time? There are plenty of good documentation tools out there such as TomDoc, YarDoc, and RDoc. These tools are useful for creating documentation for tools, gems and varies open source projects and each one has it's unique way of making documentation easier for developers. However, how do you manage documentation for a product? At Engine Yard we have our Engine Yard Cloud platform. Good external documentation for our customers is very important to us. We want to make sure they can easily understand how to use our platform and be able to accomplish what they need. However, it has been difficult to get good documentation out quickly.

Innovate Faster in the Cloud with a Platform as a ServiceEngine Yard
Presentaion: "Innovate Faster in the Cloud with a PaaS" webinar
Presenter: Jacob Lehrbaum
Date: November 18, 2011
Recorded presentation:
http://pages.engineyard.com/InnovateFasterwithPaaS.html
If you are building a new application today you are likely considering a move to the cloud. If so, you should take a careful look at Platform as a Service (PaaS). Using a PaaS makes it fast and easy to deploy and run high-impact applications by relieving the developer from having to integrate, configure, test, and maintain the platform-level software necessary to run applications. It will also improve your uptime, help you scale with your business and can even save you money.
Hiro Asari's Devoxx 2011 presentation
Presentation description:
Java developers wear many hats: they manage builds, develop applications, write command-line scripts, and must master all tiers. If only there were a way to make these tasks simple and fun.
Enter JRuby.
Build engineers can write or enhance builds with Ruby, never losing a thing they depend on from Ant or Maven. Ruby offers several elegant testing options that work great with JRuby. Web developers can create Rails applications in minutes, effortlessly incorporating the latest Web technologies while taking advantage of the existing Java libraries. JRuby supports binding native libraries with FFI (foreign function interface). Command-line scripts? They're easy with JRuby's system-level features.
Come to this session to learn how JRuby makes you a happy developer.
High Performance Ruby: Evented vs. ThreadedEngine Yard
Dr Nic Williams' Ruby Midwest 2011 presentation
Presentation description:
I wanted to know, "Do I need to learn about EventMachine or node.js? Can I use threads? What is so good or bad about threading in Ruby 1.8, Ruby 1.9, JRuby and Rubinius 2.0?"
What was important to me was that the choice was abstracted away. I wanted to write normal, step-by-step Ruby code. Yet I wanted it to be performant.
I've asked a lot of people. I even hosted EventMachine RubyConf (http://emrubyconf.com) during RailsConf 2011 in order to gather the brightest minds in the Ruby community. "What choices do I need to make, how different does my code look, and how do I do testing?" These are the questions I searched for answers to. I'd like to now share the answers.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
