Groovy Recipes is an awesome book for anyone who’s interested in learning about Groovy, or who already uses it but wants to become better at using it. The first part of the book is a great introduction to the Groovy language, different ways of using it (as a script, or compiled) and tools (the Groovy console, TextMate, Eclipse, or IntelliJ IDEA) for Groovy programming.
The middle of the book is full of recipes showing you how to accomplish useful tasks in Groovy; things like reading environment variables, or parsing and writing XML files, and creating various types of web service clients. The last part covers meta-programming with Groovy and an introduction to the Grails web framework and examples showing how to create web service providers for the web service clients described earlier in the book.
Groovy is a great language for a Java developer to learn and this book makes it easier than ever, and I highly recommend it. If you’re interested in more detail, I’ve posted a review in DZone’s IT Book Zone, or ask me about it at the next AJUG meeting.

Building and Deploying 12 Factor Apps in Scala and Java

April 18, 2017

The twelve-factor app is a modern methodology for building software-as-a-service apps:

• Use declarative formats for setup automation, to minimise time and cost for new developers joining the project.

• Have a clean contract with the underlying operating system, offering maximum portability between execution environments.

• Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration.

• Minimise divergence between development and production, enabling continuous deployment for maximum agility.

• And can scale up without significant changes to tooling, architecture, or development practices.

We will build a RESTful web service in Java and deploy the app to CloudFoundry. We will go over how to build a cloud manifest, how to keep our database credentials and application configuration outside of our code by using user-provided services and go over what it takes to build a 12 Factor application in the cloud. This presentation will be heavy on code and light on slides!
