Programming Languages: For the Common Man or the Machine? [CON3999]
Gireesh Punathil, Staff Software Engineer, IBM India Pvt. Ltd. @gireeshpunam

Programming languages are a bridge between man and machine. The more sophisticated the language, the easier it is to program, but the compiler and runtime level become harder as more-complex program directives need to be transformed into discrete, simple hardware calls. Languages take extreme steps to be humanlike and bring in disruptive constructs, but difficulties arise when it comes to enterprise-grade scaling. This session discusses a few modern languages and compares their programming interfaces with that of Java, with performance as the main consideration. The intent of the session is to showcase the implications of language constructs for the compiler and interpreter and to help you select the right language for your workload.

2:30 p.m. – 3:30 p.m. PST

Getting Started with Apache Spark: Use Scala, Java, Python, or All of Them? [CON8124]
David Taieb, STSM Cloud Data Services, IBM @DTAIEB55

Apache Spark is the next-generation distributed computing framework, rapidly becoming the de facto standard for big data analytics. It provides rich, expressive APIs in multiple languages, including Scala, Java, Python, and R. However, depending on the use case—a data scientist working in an Jupyter Notebook or a data engineer implementing long-running Spark submit jobs—choosing the right language can be a dilemma. This session uses a Spark application that performs “sentiment analysis of Twitter data” to compare and contrast the feature differences between the languages, API coverages, and overall productivity. With concrete examples, it provides insight to help you decide when to use Scala, Java, Python, or perhaps a mix of these.

4:00 p.m. – 5:00 p.m. PST
Hilton – Plaza Room B

Emerging Web App Architectures with Node.js and Java [CON1576]
Steve Wallin, Program Director, IBM @stevewallin

Java is the leader for enterprise web application development, but Node.js has been gaining popularity for developing mobile apps, APIs, and web applications. Although the two languages may appear to be in competition, they are actually very complementary. This session discusses the characteristics of the two languages and introduces emerging architectures that bring together the web scale and integrated browser experience characteristics of Node.js with the highly optimized and resilient transactional characteristics of Java to deliver reliable, highly performant, and engaging web applications. Come to this session to learn more about how Node.js and Java are being used together to build the next generation of web applications.

JVM-Assisted Clearing of Sensitive Data [CON4973]
Charlie Gracie, Advisory Software Engineer, IBM @crgracie

Does your application store any sensitive data on the Java heap? Do you rely on finalization to clean up this data? Cleaning up the single copy of the data you created may not be cleaning up all the copies. Garbage collectors may copy or move objects, causing multiple copies of your sensitive data on the heap. This session discusses the current best practices for dealing with sensitive data in the JVM and provides a demo of how the speaker would like to see the JVM modified to help.

10:00 a.m. – 11:00 a.m. PST
Hilton – Golden Gate 2/3

Euphoria Despite the Despair [CON6113]
Holly Cummins, Software Engineer/Developer, IBM @holly_cummins
Martijn Verburg, CEO, JClarity @karianna

In this session, the Mad Scientist (Dr. Holly Cummins) and the Diabolical Developer (Martijn Verburg) take an in-depth look at why the highs of zero compiler warnings are quickly canceled out by the pain of long hours, bad requirements, endless configuration, and a litany of other issues that makes death by a thousand cuts seem like a good idea. They answer questions such as “Why is programming an art?” “How can I rediscover the delight I felt when I first started coding?” and “Am I addicted to TDD?” Combining psychology, philosophy, and computer science, they present a series of practical tips to help you rediscover the euphoria you felt the very first time a metal box in front of you came to life and cried out “Hello World.”

10:00 a.m. – 11:00 a.m. PST
Parc 55 – Embarcadero

Liberty: The Right Fit for Micro Profile? [CON8119]
Kevin Sutter, Senior Technical Staff Member, IBM @kwsutter
Alasdair Nottingham, Websphere Runtime Architect, IBM @notatibm

The move to microservices is well under way, but has enterprise Java adapted to these new realities? Although some argue that enterprise Java is irrelevant, many of its tried-and-proven APIs are highly applicable to microservice architectures. And the need for new APIs to address challenges inherent in highly distributed microservices is clear. The recent announcement of the Micro Profile initiative (microprofile.io) to define new application server portable APIs means that these needs will be addressed. This session explores what Micro Profile is, how it can help with microservices, and how WebSphere Liberty’s à la carte approach to Java EE can help enable microservices by using the new Micro Profile and ldemo Liberty plus the microProfile-1.0 feature.

11:30 a.m. – 12:30 p.m. PST
Parc 55 – Cyril Magnin I

Life After Modularity: An Experience Report [CON3015]

Mind Control to Major Tom: Is It Time to Put Your EEG Headset On? [CON2338]
Steve Poole, Lead Engineer, IBM @spoole167
Luc Desrosiers, IT Architect, IBM UK

Using your mind to interact with computers is a long-standing desire. Advances in technology have made it more practical, but is it ready for prime time? This session presents practical examples and a walkthough of how to build a Java-based end-to-end system to drive a remote-controlled droid with nothing but the power of thought. Combining off-the-shelf EEG headsets with cloud technology and IoT, the presenters showcase what capabilities exist today. Beyond mind control (if there is such a concept), the session shows other ways to communicate with your computer besides the keyboard. It will help you understand the art of the possible and decide if it’s time to leave the capsule to communicate with your computer.

3:00 p.m. – 4:00 p.m. PST
Hilton – Golden Gate 4/5

Java, the Cloud, Containers: Migrating Without the Tiers (or Tears) [CON3601]
Steve Poole, Lead Engineer, IBM @spoole167
Daniel Bryant, Chief Scientist, OpenCredo @danielbryantuk

Everyone is talking about building “cloud native” Java applications—and taking advantage of microservice architecture, containers, and orchestration/PaaS platforms—but there is surprisingly little discussion of migrating existing legacy (moneymaking) applications. This session aims to address this, and, using lessons learned from several real-world examples, it covers topics such when to rewrite applications (if at all), modeling/extracting business domains, applying the “application strangler” pattern, common misconceptions with “12-factor” application design, and the benefits/drawbacks of container technology.

4:30 p.m. – 5:30 p.m. PST
Parc 55 – Cyril Magnin I

Java EE Microservices by Example, from Raspberry Pi’s to the Cloud [CON6245]
Holly Cummins, Software Engineer/Developer, IBM @holly_cummins

Making the move to a microservice architecture can be pretty daunting. Microservices can solve many architectural and organizational problems, but they come with their own challenges. Getting from monolith to microservices can be even harder. What’s the cleanest way to refactor? How should things be tested? What if things go wrong? Using a pile of tiny computers, cables, and code, this session demonstrates carving a monolith into microservices and deploying—and managing—a microservices application. Because there are limits on how much traffic the data-center-in-a-handbag server topology can handle, the presentation also demonstrates scaling up, out, and away to the cloud.

4:30 p.m. – 5:30 p.m. PST
Parc 55 – Embarcadero

Game On! Exploring Microservices with a Text-Based Adventure Game [CON1559]
Erin Schnabel, Senior Software Engineer, IBM @ebullientworks

Creating a single microservice is easy, as walkthroughs everywhere show. See? Add a few annotations, invoke this command to build it, and you have a running microservice! Ta-da! But what happens next? Game On! is an interactive text adventure written as a collection of microservices to help people answer that very question. This session covers how the speaker and her colleagues used service composition and discovery, API definition and versioning, security (authentication, authorization, and identity propagation), the 12 factors, and a combination of lightweight protocols to build the game. The presentation also discusses what they learned from building it and from others extending it.
