NEJUG becomes
Boston Java Users ACM Chapter 

  • Welcome to Boston Java Users ACM Chapter

    The Boston Java Users ACM Chapter (formerly NEJUG) 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.

  • Want to help?

    NEJUG is a volunteer driven organization, we can always use help from our community members, we can use your help with organizing the monthly meetings, adding new features and maintaining the website etc.,

      • Mutation Testing


        Thursday February, 09, 2023 06:30 PM

      Most developers are familiar with the concept of unit testing, and how this is useful to ensure validity of your code. Java developers will typically use JUnit to write their unit tests. Many projects use test coverage tools such as Jacoco to ensure that the code as written has tests to validate it. But how strong are the tests? Will they stand up against bugs introduced by future code changes? This talk will cover using PIT to walk through a Java code example to illustrate mutation testing.

      • Quarkus for Spring Developers


        Thursday January, 12, 2023 06:30 PM

        0

      In this session, we will show concepts and conventions familiar to Spring developers and how those same
      concepts and conventions can be implemented in Quarkus, all while highlighting similarities and differences
      between them. Additionally, we will show similarities and differences in how testing is done, highlighting Quarkus
      Dev Services.
      We will also introduce the Spring compatibility in Quarkus and how to quickly migrate a Spring Boot microservice
      application to Quarkus with little-to-no code changes. Time permitting, we may even convert a Spring Boot
      microservice into Quarkus, live.

      • Getting Started with JReleaser


        Thursday November, 10, 2022 06:30 PM

        0

      Your project has reached that stage when it's a good idea to post binaries, but new questions appear such as where should they be posted? How do make it easier for users to install and discover your binaries? Where should releases be announced? Most importantly, can answers to these questions be automated? Enter JReleaser, a tool that provides answers to these questions and more.
      JReleaser may be used to create GitHub/GitLab/Gitea releases and publish binaries that can be consumed from different distribution channels such as Homebrew, Snap, Scoop, and more. Once published, the release can be automatically announced on Twitter, Slack, Gitter, Discord, and other communication channels.

      • Codin'-Up Some Chaos


        Friday October, 14, 2022 06:30 PM

        0

      Don't fear entropy, embrace it.
      When you move toward distributed computing the likelihood of failure proportionally increases. It's not your fault, it's simply physics. Once you start spreading your data and applications across more devices, then access to resources such as CPU, memory, and I/O has a higher rate of failure.
      Embrace entropy with chaos experiments and increase your cloud native capability model. We'll first investigate how to design Chaos experiments with Java then we'll investigate some of the leading chaos frameworks for Kubernetes and dive into hands-on experiments targeted within blast radiuses.

      • Event Streaming and Processing using Apache Pulsar


        Thursday September, 15, 2022 06:30 PM

        0

      The world is moving at an unprecedented pace and much of it has been powered by the innovations in software and systems. While event handling, messaging, and processing are not necessarily brand new concepts, the recent emergence in hardware such as virtualizations, multi-core processors, and so on, are in fact pushing the envelope in software design and development, elevating it to higher levels of capabilities never seen before. In the case of streaming which very often leverages on the underlying messaging mechanism(s) to bring distributed messaging to higher forms of purposes, such as IoT/IIoT applications, AI/ML data pipelines, or even eCommerce recommendations, event streaming platform has indeed become the “glue” in enabling data to flow through disparate systems in the pipeline and in a very dynamic fashion.

      This talk on event streaming is meant for anyone interested in learning about it, and understanding how it fits into the modern software development design and architecture, as well as seeing some of the challenges it faces especially in the Cloud Native environment. We’ll then take a look at an open source platform - Apache Pulsar, which is poised to become the de facto new generation of distributed messaging and streaming platform that will bring joy to developers, and enable systems and applications to be highly responsive with its true real-time capabilities.

      • Put Your Best Boot (Spring) Forward: Spring Boot Best Practices


        Thursday July, 14, 2022 06:30 PM

        0

      In this example-driven session, we'll review several tips and tricks to make the most out of your Spring development experience. You'll see how these tips fit into a real (albeit small) Spring application and be able to take them with you as you apply them to your project.

      Spring has been the de facto standard framework for Java development for nearly two decades. Over the years, Spring has continued to evolve and adapt to meet the ever-changing requirements of software development. And for nearly half that time, Spring Boot has carried Spring forward, capturing some of the best Spring patterns as auto-configuration.

      As with any framework or language that has this much history and power, there are just as many ways to get it right as there are to get it wrong. How do you know that you are applying Spring in the best way in your application?
