This document provides an introduction to Groovy and Grails. It discusses how Groovy is an agile and dynamic language for the Java Virtual Machine that builds on Java's strengths with features from languages like Smalltalk, Python and Ruby. Groovy code seamlessly integrates with Java code and objects. The document demonstrates differences between Java, Groovy and Ruby code. It also covers Groovy features like GStrings, closures, meta-programming and builders. Finally, it mentions Grails, a web framework that uses Groovy.
Groovy is a dynamic language for the Java Virtual Machine that aims to provide features similar to languages like Python and Ruby. Some key differences from Java include fewer imports needed, truthiness, new operators like Elvis and spread-dot, and features like closures and duck typing. Best practices for Groovy include using its idioms like closures, experimenting, and using explicit types where appropriate.
This document is a presentation about the new features in Groovy 1.6. It discusses improvements to Groovy's performance, new syntax enhancements like multiple variable assignment, the introduction of compile-time metaprogramming via AST transformations, and various other new features and improvements. The presentation was given by Guillaume Laforge, the project manager of Groovy at SpringSource, to explain the updates in the latest version of Groovy.
There are three main ways to embed Groovy in a Java application:
1) Compiling Groovy code to Java bytecode that can be referenced from Java code. This can be done with Maven or Ant.
2) Using the Bean Scripting Framework (BSF) or JSR 223 to execute Groovy scripts at runtime from Java.
3) Native embedding using the GroovyShell, GroovyClassLoader, or GroovyScriptEngine APIs to load and execute Groovy code from Java. Performance considerations include caching compiled scripts and reloading when dependencies change.
Apache Groovy: the language and the ecosystemKostas Saidis
An overview of the Groovy language and its awesome ecosystem, advocating Groovy as the language of choice for (a) Java developers that want to dive into dynamic languages or (b) for Javascript, Ruby or Python developers that want to dive into the Java platform.
The presentation was given at the 9th FOSSCOMM (16-17 April 2016) organized by the Software Libre Sociecy of the University of Piraues.
The document discusses differences between Ruby and Scala programming languages. Some key similarities include both being class-based object-oriented languages with functional features. Differences include Scala using explicit types while Ruby is dynamically typed, and Scala having separate concepts of methods and functions while Ruby blurs the distinction. The document also compares features like class definitions, collections, functions as values, and enhancing existing classes.
Slides from my talk at Greach 2014:
"Groovy is a dynamic language that provides different types of metaprogramming techniques. In this talk we’ll mainly see runtime metaprogramming. I’ll explain Groovy Meta-Object-Protocol (MOP), the metaclass, how to intercept method calls, how to deal with method missing and property missing, the use of mixins and categories. All of these topics will be explained with examples in order to understand them.
Also, I’ll talk a little bit about compile-time metaprogramming with AST Transformations. AST Transformations provide a wonderful way of manipulating code at compile time via modifications of the Abstract Syntax Tree. We’ll see a basic but powerful example of what we can do with AST transformations."

"We'll burn that bridge when we get to it”—Technology, Metadata Standards, an...Jennifer Liss
Linked data, RDA, and shelf ready processing are relatively recent developments in a long evolution of library technology, metadata standards, and technical services workflows. Although change has been a constant fixture of the cataloger's reality, change is nonetheless disruptive—sometimes, bridges burn. This session takes a historical view of cataloging and metadata creation from the time of Cutter to the dawn of semantic search. The evolution and interplay of technology, metadata standards, and workflows—the tools of our trade—will be considered. What were the roles of catalogers during times of transition? Which personal and professional strengths have proven invaluable over the last century? How does any of this help our community interpret developments in linked library data or user-centered resource discovery? The presenter will propose a framework for interpreting changes in library technology, metadata standards, and technical services workflows. By viewing such changes through the lens of cataloging competencies, our community might navigate into new territory and cooperate in the building of new bridges.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock
Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results.
News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?
TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc
Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency.
This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data.
Attendees will learn:
- Consumer awareness around data brokers and what consumers are doing to limit data collection
- How businesses assess third-party vendors and their consent management operations
- Where business preparedness needs improvement
- What these trends mean for the future of privacy governance and public trust
This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

2. ‣ Builds upon the strengths of Java but has additional power features
inspired by languages like Python, Ruby and Smalltalk
‣ Makes modern programming features available to Java developers with
almost-zero learning curve
‣ Supports Domain-Specific Languages and other compact syntax so your
code becomes easy to read and maintain
‣ Simplifies testing by supporting unit testing and mocking out-of-the-box
‣ Seamlessly integrates with all existing Java objects and libraries
‣ Compiles straight to Java bytecode so you can use it anywhere you can use Java
5. "Groovy is like a super version
of Java. It can leverage Java's
enterprise capabilities but also
has cool productivity features
like closures, builders and
dynamic typing. If you are a
developer, tester or script guru,
you have to love Groovy."
9. Development modes (development, test, production, custom)
• Built-in web server
• Hot deploy / class reloading without restarting the server
• ORM (Object Relational Mapping)
• Lots of plugins, that can be downloaded from the command line / plugin
manager
• Simple routing configuration
• Model, view, controller, and test generators
• Active community
• Easy to learn
• Full stack frameworks
• Console (groovysh / groovyConsole)
• Easy to configure
• Builders
• Very easy to create tags / reusable HTML components
• Convention over Configuration
10. Services
Classes which contain business logic but are not
necessarily tied to a specific domain class (ie. model)
