Presentation from Riga Dev Day talking about Lambda expressions and the Stream API in JDK8. This session, as the title suggests, goes beyond the basics and discusses some of the different ways you need to think to use a functional style of programming in Java.
Functional Programming With Lambdas and Streams in JDK8IndicThreads
The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: java.util.stream and java.util.function.
After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created.

Project Lambda: Functional Programming Constructs in Java - Simon Ritter (Ora...jaxLondonConference
Presented at JAX London 2013
The big language features for Java SE 8 are lambda expressions (closures) and default methods (formerly called defender methods or virtual extension methods). Adding lambda expressions to the language opens up a host of new expressive opportunities for applications and libraries. You might assume that lambda expressions are simply a more syntactically compact form of inner classes, but, in fact, the implementation of lambda expressions is substantially different and builds on the invokedynamic feature added in Java SE 7.

Automatic Migration of Legacy Java Method Implementations to InterfacesRaffi Khatchadourian
Java 8 is one of the largest upgrades to the popular language and framework in over a decade. In this talk, I will first overview several new, key features of Java 8 that can help make programs easier to read, write, and maintain, especially in regards to collections. These features include Lambda Expressions, the Stream API, and enhanced interfaces, many of which help bridge the gap between functional and imperative programming paradigms and allow for succinct concurrency implementations. Next, I will discuss several open issues related to automatically migrating (refactoring) legacy Java software to use such features correctly, efficiently, and as completely as possible. Solving these problems will help developers to maximally understand and adopt these new features thus improving their software.

Microservices is the dominant architecture for developing new applications, as it is ideally suited to cloud deployments. When using JVM-based services, each instance works in isolation and has no awareness of previous runs of a service. The Cloud Native Compiler detaches the JIT compiler from individual JVMs and centralises it in the cloud, effectively a JIT-as-a-Service. The benefits of this are caching of compiled code for instant reuse, use of greater resources for higher optimisation as well as many others. The session will discuss the challenges of cloud-based JVMs and how we can significantly improve performance with reduced costs.
The Java Virtual Machine (JVM) can deliver significantly better performance through the use of Just In Time compilation. However, each time you start an application it needs to repeat the same process of analysis and compilation. This session discusses Java with Co-ordinated Checkpoint at Restore. This is a way to freeze an application and start it again (potentially many times) from the same checkpoint.
This session, delivered at Devoxx Poland, covers all the major changes to the Java platform between JDK 12 and JDK 17. All language features are covered, as well as many of the important API changes.
How to monitor Java application and JVM performance with Flight Recorder and Mission Control. Starts with a discussion of general JVM performance considerations like GC, JIT and threads.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

We define a Lambda expression as an anonymous function (like a method, but because it is not associated with a class we call it a function). Like methods there are parameters, a body, a return type and even thrown exceptions.
What Lambda expressions really brings to Java is a simple way to parameterise behaviour. The sequence of methods we have here defines what we want to do, i.e. filter the stream, map its values and so on, but how this happens is defined by the Lambda expressions we pass as parameters.
Erased function types are the worst of both worlds
Stream is an interface, but in Java SE 8 we can now have static methods in interfaces, hence Stream.of()
