• Jamming with a Quantum Computer: A musical journey into quantum computing

    Can't make it in person? Join the zoom at 6:30PT https://pivotal.zoom.us/j/2699571656 Musical improvisation is the creative activity of composing music "in the moment" while performing it, often in a jam session with other musicians. Although composing and performing music is a creative process, the underlying musical style informs the probabilities of note and rhythmic choices that the musician makes. For example, when improvising in the style of twelve-bar blues, the notes played with the highest frequency of occurrence are typically the five that comprise the corresponding minor pentatonic scale. This idea of musical style being a complex system of probabilities fits perfectly with the probabilistic nature of quantum mechanics, which is a phenomenon leveraged by quantum computing. To implement this idea, James Weaver created an open source application named Quantum Music Composer that makes use of a quantum computer to improvise music in a very simplified version of 17th century counterpoint. In this session, James will give an introduction to quantum computing, cover a bit of music theory, and demonstrate how a quantum computer can compose music and participate in a musical jam session. He will then discuss the development and implementation of the Quantum Music Composer application on IBM, and Rigetti, quantum computers. Info for committee This session is a brief but gentle introduction by James Weaver to quantum computing for developers and other IT professionals. The presentation consists of demonstrations, code samples, and slides. Because we’ll be accessing real quantum computers in the cloud and playing the music that they improvise, technical requirements include a reliable internet connection, connection to the room's sound system, and a hands-free microphone. Speaker bio James Weaver is a developer, author, and speaker with a passion for quantum computing. He is a Java Champion, and a JavaOne Rockstar. James has written books including Inside Java, Beginning J2EE, the Pro JavaFX series, and Java with Raspberry Pi. As an IBM Quantum Developer Advocate, James speaks internationally at quantum and classical computing conferences. He tweets as @JavaFXpert, and blogs at http://JavaFXpert.com and http://CulturedEar.com

  • A Java framework for High speed ingest of streaming data

    Can't make it in person? Join the zoom at 6:30PT https://pivotal.zoom.us/j/534680369 We will present a new Java library that allows Java programs to stream data into databases at high speed using a simple API. The typical use case consists of a large number of clients or IoT devices emitting data to be persisted and that must not be blocked, waiting for a synchronous response from the database. The library relies on advanced performance and scalability techniques such as direct path insertion protocol, partitioning, sharding, and data affinity. The session includes a working prototype (demo) and code samples.

  • Special Event: Java 12 Launch @ Oracle HQ Redwood Shores

    Special event with the Java team at Oracle HQ and Silicon Valley JUG https://www.meetup.com/sv-jug/ If you can't join in person we will be streaming the event at https://pivotal.zoom.us/j/374883715 5:30-7:00: Socializing & Food 7:00 - 8:30: Presentation and Q&A (20 Min) Georges Saab (VP, Java Platform Development) JDK: State of the Union In the past two years, Java have changed in three ways that we never have before: The platform has been modularized, some components have been removed, and the pace of new releases has been accelerated. These changes aim to keep Java vibrant in an ever-changing world of competing platforms and new styles of application deployment, whether to the cloud or to app stores. Evolution can be disruptive, but evolution is not as scary as you may think, and many developers have already adjusted to them. Learn how Oracle is advancing Java to meet the productivity needs of developers in the fast changing world of technology we live in. -- (20 Min) Bernard Traversat (VP, Java Platform Development) Celebrating the Java 12 Launch - Shaping the Future of Java, faster! Come celebrate the release of Java 12 and get an overview of what's new, and see a deeper dive on some of the new features such as switch expressions and the new GC enhancements. We’ll also take a peek at some of the features under development at OpenJDK for future releases and discuss when we might see them in production. -- (40 Min) Georges Saab, Bernard Traversat, Mikael Vidstedt, Stuart Marks, Alex Buckley, and Sharat Chander Ask the Java Experts Panel Got a question about why Java is the way it is, or where it is going? Bring your favorite questions about the Java Platform and the Java Development Kit — past, present, or future —to this open Q&A session with key experts from Oracle's Java team.

  • Bootiful Reactive Testing

    Pivotal Labs

    Can't make it in person? Join the zoom at 6:30PT https://pivotal.zoom.us/j/2699571656 Speaker: Mario Gray, Pivotal Evangelist Team Join us for an exploration of testing a reactive Spring Boot 2.x application. Test driven development gives us the confidence necessary to improve our code faster, safely. But how do you test components and services, as well as integrations across distributed systems, while maintaining fast feedback loops, and how do you do all of this within the context of reactive Java? In this talk, we'll look at how to test imperative components, reactive data flows, and mocks. We’ll examine how to take advantage of test slices, and how to test web applications. We'll look at how to ensure that API producers and consumers work well together using consumer driven contract testing without sacrificing the testing pyramid for end-to-end integration tests. And we’ll do it all within the context of reactive programming. Mario Gray (@mariogray): Currently a Principal Technologist for Pivotal. Mario has worked in software for startups and large financial services enterprises alike working across the stack from server/network design to application design. He's professionally written software to entertain, bring people together, and drive businesses using technologies like Linux/Solaris,SQL/NOSQL,AWS/SALT,Spring/J2EE. Mario is confident that the future of cloud computing belongs to Pivotal and the Spring team for some time to come. A longtime open-source champion, Mario is co-author of Apress’ Pro-Spring Integration, as well as a contributor to the Spring and Integration projects.:

  • Welcome to JUnit 5!

    Pivotal Labs

    Attending remotely? Join here! (Won't be live until event starts). https://pivotal.zoom.us/j/2699571656 It’s been a little more than a decade since JUnit 4 was released and a lot of has changed in the Java world, it’s time our testing framework changed too! JUnit 5 was a top down rewrite of the popular unit testing framework and during this presentation we will look at the goals of the rewrite and how the new programming model will provide more flexibility when writing your test cases. This presentation will also cover how to migrate your existing test suite to JUnit 4, both in the initial switch, which is a simple dependency change, but also the more laborious and complex task of getting your existing tests to start running on JUnit 5 natively. Bio: Billy is a developer advocate with IBM and has over a decade of experience. Billy is passionate about finding ways to reduce mental capacity waste from tedious work; such as project initiation, deployment, testing and validation, and so on through automation and good management practices. Outside of work Billy enjoy traveling, playing kickball, and having his heartbroken by cheering on the Kansas City Chiefs.

  • Reactive Relational Database Connectivity

    Pivotal Labs

    Speaker: Ben Hale, Pivotal https://springoneplatform.io/2018/speakers/ben-hale As more and more projects start incorporating reactive programming, they start to discover that the only way to get the full benefit of that change is to ensure that they have a fully reactive stack. There are a number of messaging systems and data stores that enable this fully reactive stack, but there has been a big piece missing when it comes to accessing relational database systems in a fully reactive way. This talk presents the Reactive Relational Database Connectivity (R2DBC) project. The project is a test-bed for what a reactive API would look like when paired with relational database access. This talk will explain how the API works, the benefits of using it, and how it contrasts with the ADBC project proposed as a successor to JDBC.
