  • Welcome to NEJUG

    The New England Java Users Group is open to everyone interested in Java and the JVM. Meetings are usually held on the second Thursday of each month. The meetings and membership are free. We do not hold meetings in July and December. The NEJUG was formed in November 1998. We currently have over 6000 members. Meeting space is limited and we must ask members to register in order to attend meetings. It is common for over 300 people to register for a single meeting! What better way to meet new people interested in Java, development, architecture, or just get your technical questions answered.

      • Developer Productivity Engineering

        Attended: 86

      With software projects becoming more and more complex, delivering new features into production quickly and safely has become a major challenge for most software organizations today. Making sure developers are able to develop and deploy new features in rapid cycles is a key success factor, but this task has long been neglected. The most successful software organizations are prioritizing this key success factor through a new practice called Developer Productivity Engineering. This practice is based on a culture where the entire organization collaborates to maximize developer productivity.

      This talk will address the questions:

      • What are the challenges organizations are facing regarding developer productivity?

      • Who is responsible for maximizing developer productivity?

      • Which skills are required in developer productivity engineering?

      • What tools do teams use to measure and improve their productivity?

    • While many platform-level operational tasks have been automated with Kubernetes and operators, managing individual microservices and applications is often still a highly manual task. Even cloud-native applications often rely on runbooks and hand-crafted pipelines. In many cases, these practices even differ from application to application.

      The Dynatrace innovation lab saw the same problem and built an open-source fabric for autonomous declarative operations called Keptn (pronounced “Captain.") Keptn provides a ready-to-use framework for GitOps-based pipelines, standardized deployment models, monitoring and operations as a service. Keptn also allows automating operational tasks with runbook automation and self-healing. With Keptn, Developers can focus on code instead of creating YAML files, DevOps can focus on tools instead of building pipelines, SREs can enforce processes instead of debugging problems.  We have recently released Keptn 0.4.0 (http://keptn.sh) and plans are underway to submit the project for incubation within the Cloud Native Computing Foundation (https://www.cncf.io/).

      In this talk, we will share information on:

      • WHY we've built Keptn
      • its technical underpinnings
      • share current project status
      • discuss how the community could help! 

      The talk also has live demos of onboarding an application comprised of Spring Boot application services and deploying through a multi-stage pipeline orchestrated by Keptn.

      • Polyglot Java EE on the GraalVM

        Attended: 40

      The new GraalVM from Oracle supports multiple languages including JavaScript, Python, Ruby, R, C++ as well as Java and other JVM languages. This opens up interesting possibilities for polyglot enterprise applications. Now you can use a Node library in a Java application or call an R statistical function from an EJB. Previously, this type of integration was extremely challenging. This session will provide recipes to get up and running along with best practices and some cool demos.

      We would like to thank our event host https://www.jobcase.com for all the support for making this event possible in Cambridge.

      • The venue will open at 5:30 PM for networking, so come early and meet everyone else. 
      • Pizza, drinks sponsored by Jobcase --- there will be some Gluten-free items as well.

       

       

       

      • Kotlin: Beyond the Basics

      This talk will examine features of Kotlin at a greater depth than most tutorials. Higher order functions will be covered, as well as reduction operations like reduce and fold, and lambdas with receivers. Those topics progress toward building DSLs and builders in Kotlin. Terms like “apply”, “let”, “use”, “also”, and “with” will be covered along with their typical use cases. Finally, an introduction to Kotlin coroutines will be included.

      Details of the type system, including the Any, Unit, and Nothing classes, will be covered. Examples will be provided on how to define extension functions, infix operators, and inlining functions for efficiency.

    • Java is a language in evolution. There are a handful of language changes in Java 9 and 10 plus several JDK changes in 9, 10, 11, and 12. Some of these changes are significant in that they allow us to do things more effectively than before. The difference can be anywhere from reducing code to avoiding errors that come from verbosity. In this presentation we will explore the language changes first. Then we will visit the additions to the JDK. Along the way we will also look at a few things that have been removed from Java as well.
