Spring Boot Goals
➔ Introduce developers to Spring Boot, an opinionated way to rapidly build production
grade Spring applications quickly and with minimal fuss.
➔ Be opinionated out of the box, but get out of the way quickly as requirements start to
diverge from the defaults
➔ Provide a range of non-functional features that are common to large classes of
projects (e.
g. embedded servers, security, metrics, health checks, externalized configuration)
➔ Absolutely no code generation and no requirement for XML configuration!

Spring Boot Goals…
➔ Single point of focus (as opposed to large collection of spring-* projects)
➔ A tool for getting started very quickly with Spring
➔ Common non-functional requirements for a "real" application
➔ Exposes a lot of useful features by default
➔ Gets out of the way quickly if you want to change defaults

Practical continuous quality gates for development processAndrii Soldatenko

There are a lot of books and publications about the continuous integration in the world. But in my experience it’s difficult to find information about how to open quality gates between automated tests and to continuous integration practice to in your current project. After reading several articles and even a couple of books you will understand how to work with it. But what next? I will share with you practical tips and tricks on how to lift iron curtain to your automated tests before a continuous quality practice today. It is for this reason why I am pleased to share with you my acquired experience in my presentation.

Introduction to continuous deliveryLeena N

Continuous delivery is a software development practice where software can be released to production at any time by building software in a way that enables frequent, automated releases. It involves practices like continuous integration, where code is automatically merged and tested frequently, automated testing and deployment, and using deployment pipelines and tools to streamline the release process. Many large tech companies practice continuous delivery, with some deploying new code in minutes or every 11 seconds to get changes to users quickly.

Merge hells - Feature Toggles to the rescueLeena N

The document discusses how feature toggles can help address "merge hells" that can occur with continuous integration. Feature toggles allow incomplete features to be deployed without being released, avoiding the need to rollback deployments. They enable options like A/B testing, canary releasing, and managing experimental and operations toggles. To manage feature toggles, teams should follow mainline development practices, use feature toggle tools, set expiry dates for toggles, and consider toggles as a first step towards continuous delivery.

Angular Ivy- An OverviewJalpesh Vadgama

Ivy is Angular's next generation compiler and renderer that aims to make applications smaller, faster to load, and use less memory. Some key goals of Ivy include faster initial loading, reduced bundle sizes, lower memory footprint, improved memory allocation, and faster compilation times. Ivy generates template instructions directly from templates rather than generating intermediate metadata, making the compilation process more efficient. It also uses incremental DOM for rendering, which creates and updates DOM trees using in-place instructions rather than full virtual DOM comparisons on each change. Tree shaking also works more effectively with Ivy due to its generation of smaller, more atomic functions from templates.

Protractor end-to-end testing framework for angular jscodeandyou forums

Protractor is an end-to-end test framework for AngularJS applications that runs tests against a real browser, interacting with the application as a user would. It is built on WebDriverJS and uses native events and browser-specific drivers to test asynchronous behavior and support for AngularJS. Protractor tests can run in any browser and interact directly with page elements rather than testing JavaScript code.

Angular TS(typescript)Ivan Stepić

This document discusses using TypeScript with Angular to prepare code for migration to Angular 2. It recommends using TypeScript for its static typing and compile-time type checking. It provides steps for modifying an existing Angular project to use TypeScript and approximate Angular 2 components to ease the migration. Key aspects include refactoring data flows, replacing ng-include and ng-controller with component directives, and wrapping markup in component directives.

All you need is Zap - Omer Levi Hevroni & Yshay Yaacobi - DevOpsDays Tel Aviv...DevOpsDays Tel Aviv

Dynamic Security Testing Zap is a free and open source security testing tool that can find vulnerabilities in web applications. It has two modes - passive and active scanning. Passive scanning inspects traffic while active scanning attacks the application by running exploits. Zap found issues like insecure cookies and missing security headers during passive scanning of Tweek. For active scanning, Zap parsed Tweek's OpenAPI specification and found additional vulnerabilities. Glue is an OWASP tool that helps integrate Zap and other security tools into continuous integration pipelines. It filters and reports findings to help prioritize issues. Adding security testing with Zap and Glue helped find and fix vulnerabilities before they affected users.

Protractor provides AngularJS-specific APIs and tools to help with debugging on top of WebDriverJS. Functional tests are the foundation of quality but should be isolated and decoupled from the UI using patterns like page objects. Protractor is ready to use today for testing AngularJS applications.

Testing, CI and CD in the real worldRoc Boronat

The document discusses different types of software testing including unitary tests, integration tests, and instrumentation tests. It provides examples of how unitary tests can be used to develop regular expressions, parse deep links, improve an invoice generator, and refactor legacy code. Tips are provided on following a given-when-then style for unitary tests and testing one thing at a time. Integration tests and instrumentation tests are discussed for developing APIs and testing apps end-to-end. Continuous integration and continuous delivery are also summarized.

Automated Testing using JavaScriptSimon Guest

Automated testing of web applications using JavaScript can provide confidence that changes and new installations do not break existing functionality. There are various types of tests, including unit, end-to-end, compatibility, and performance tests. Popular JavaScript testing tools include QUnit for unit testing, Selenium and Protractor for end-to-end testing, and PhantomJS for headless browser testing without a GUI. These tools can test JavaScript applications and allow writing tests in JavaScript when the application itself is also written in JavaScript.

Java and services code lab spring boot and spring data using mongo dbStaples

Easy data-with-spring-data-jpaStaples

Java and Spring Data JPA: Easy SQL Data Access Abstract Presenter: Miya W. Longwe, MBA, MSE, Tech Lead, Staples, Inc, Framingham MA 01702 Accessing data repositories in various applications programming languages typically involves writing of tedious boilerplate lines of code. Some application development frameworks such as Spring have tried to make the experience more succinct by providing abstraction layers such as HibernateTemplate and JdbcTemplate, etc. Despite these APIs, the developers still spend a lot time writing repetitive code than concentrating on implementing business requirements. Developers at Spring, led by Oliver Gierke, introduced Spring Data JPA which “aims to significantly improve the implementation of data access layers by reducing the effort to the amount that's actually needed. As a developer you write your repository interfaces, including custom finder methods, and Spring will provide the implementation automatically”. Spring Data JPA provides a powerful, out-of-the-box alternative to creating your own DAO framework. You declare custom repository operations on an interface, and the framework generates dynamic implementations (not code generation) automatically, based on conventions around method names. As part of the presentation, we'll also review a demo to look at Spring Java configuration (as opposed to XML configuration), and investigate the @Profile annotation – configuration details which may make life a bit easier in various ways when setting up unit testing of our repository classes, using out-of-the-box alternative to creating DAO framework, how to create custom repositories, pagination and support for custom queries among other features. Presenter's Bio Miya W. Longwe is a Senior Software Engineer and Tech Lead at Staples, Inc. where he is currently working on an initiative to re-platform the company’s ecommerce architecture to offer platform-driven, modular products that can be quickly customized, enhanced, and branded as needed. Miya has been a software professional since 1997. His 16 years software development career includes working for large companies to small startups, building solutions for enterprises and consumers, working with a broad range of technologies. Miya Longwe is a hands-on java developer. He believes that in order to be a relevant and effective software developer one needs to remain a deeply knowledgeable, up-to-date, and productive software developer. His research interests include model-driven engineering, domain specific languages, test driven development and project risk management. Miya graduated from the University of Malawi (Lilongwe, Malawi) and has an MBA from the University of Wales Cardiff Business School (Wales, UK) and a Masters in Software Engineering from Brandeis University (MA, USA). Occasionally, Miya can be spotted fishing the banks of the south shore (MA) with his two boys, William and Daniel.

Building a Spring Boot Application - Ask the Audience! (from JavaLand 2017)🎤 Hanno Embregts 🎸

Spring Boot makes it easy to create stand-alone Spring-based application that you can 'just run'. It uses a 'convention over configuration' approach to get you up and running in no-time, while offering all Spring features that you have grown fond of in the past years. In this session this is demonstrated by live-coding a Spring Boot application that will just work. But audience beware, this is not your standard live-coding session'. Attendees will have a vital say in the session's content by defining the applications requ irements. Should it be an app to track your kitchen cupboard contents or do you want a simple task planner? It's up to you! Should it use MongoDB or Couchbase? You decide! Do you want an AngularJS front-end with a RESTful backend or do you prefer a classic web app with Thymeleaf templates? It's your call! Seriously. During the session you get to make these decisions by participating in an online vote. And you will discover that Spring Boot is up to the task no matter what choices you make. So what are you waiting for? Bring your own device, help shape the application that we're building and learn lots about Spring Boot in the process. This session is intended for Java software engineers with an interest in Spring Boot. Some Spring experience could come in handy, but is not strictly necessary. After this session, you will know enough to start your own Spring Boot project.

Scaling FME Flow on Demand with Kubernetes: A Case Study At Cadac Group SaaS ...Safe Software

In today’s data-driven world, efficiency is key. For Cadac, a Dutch leading provider of SaaS solutions and Autodesk Platinum partner, ensuring that customers can process data on demand is crucial to delivering a seamless experience. However, with fluctuating user demand, a challenge emerged: How do we scale FME Flow to meet on-the-fly processing needs without over-investing in infrastructure? Enter Kubernetes and KEDA (Kubernetes Event-Driven Autoscaling). In this presentation, we will explore how these cutting-edge technologies helped dynamically scale FME Flow engines based on real-time demand, without wasting resources. Instead of relying on the standard Kubernetes autoscaling based on CPU and RAM metrics, which can lead to ineffective scaling, KEDA can integrate directly with the FME Flow REST API. This allowed autoscaling based on the actual number and type of jobs in the queue. Now, whenever demand spikes, Kubernetes automatically spins up additional machines tailored to the type of workload—whether it’s CPU-intensive tasks or memory-heavy processes—ensuring optimal performance and cost-efficiency. While afterwards also autoscaling to zero, to reduce costs. Join us as we dive into how this approach helped Cadac scale on demand, reduce infrastructure costs, and provide a better experience for their customers. This session will feature both a technical walkthrough and insights on the real-world impact and value this solution has delivered to their platform and client.

Automating Map Production With FME and PythonSafe Software

People still love a good paper map, but every time a request lands on a GIS team’s desk, it takes time to create that perfect, individual map—even when you're ready and have projects prepped. Then come the inevitable changes and iterations that add even more time to the process. This presentation explores a solution for automating map production using FME and Python. FME handles the setup of variables, leveraging GIS reference layers and parameters to manage details like map orientation, label sizes, and layout elements. Python takes over to export PDF maps for each location and template size, uploading them monthly to ArcGIS Online. The result? Fresh, regularly updated maps, ready for anyone to grab anytime—saving you time, effort, and endless revisions while keeping users happy with up-to-date, accessible maps.

Leveraging Foundation Models to Infer IntentsKeheliya Gallaba

Invited Talk at RAISE 2025: Requirements engineering for AI-powered SoftwarE Workshop co-located with ICSE, the IEEE/ACM International Conference on Software Engineering. Abstract: Foundation Models (FMs) have shown remarkable capabilities in various natural language tasks. However, their ability to accurately capture stakeholder requirements remains a significant challenge for using FMs for software development. This paper introduces a novel approach that leverages an FM-powered multi-agent system called AlignMind to address this issue. By having a cognitive architecture that enhances FMs with Theory-of-Mind capabilities, our approach considers the mental states and perspectives of software makers. This allows our solution to iteratively clarify the beliefs, desires, and intentions of stakeholders, translating these into a set of refined requirements and a corresponding actionable natural language workflow in the often-overlooked requirements refinement phase of software engineering, which is crucial after initial elicitation. Through a multifaceted evaluation covering 150 diverse use cases, we demonstrate that our approach can accurately capture the intents and requirements of stakeholders, articulating them as both specifications and a step-by-step plan of action. Our findings suggest that the potential for significant improvements in the software development process justifies these investments. Our work lays the groundwork for future innovation in building intent-first development environments, where software makers can seamlessly collaborate with AIs to create software that truly meets their needs.

zOS CommServer support for the Network Express feature on z17zOSCommserver

The IBM z17 has undergone a transformation with an entirely new System I/O hardware and architecture model for both storage and networking. The z17 offers I/O capability that is integrated directly within the Z processor complex. The new system design moves I/O operations closer to the system processor and memory. This new design approach transforms I/O operations allowing Z workloads to grow and scale to meet the growing needs of current and future IBM Hybrid Cloud Enterprise workloads. This presentation will focus on the networking I/O transformation by introducing you to the new IBM z17 Network Express feature. The Network Express feature introduces new system architecture called Enhanced QDIO (EQDIO). EQDIO allows the updated z/OS Communications Server software to interact with the Network Express hardware using new optimized I/O operations. The new design and optimizations are required to meet the demand of the continuously growing I/O rates. Network Express and EQDIO build the foundation for the introduction of advanced Ethernet and networking capabilities for the future of IBM Z Hybrid Cloud Enterprise users. The Network Express feature also combines the functionality of both the OSA-Express and RoCE Express features into a single feature or adapter. A single Network Express port supports both IP protocols and RDMA protocols. This allows each Network Express port to function as both a standard NIC for Ethernet and as an RDMA capable NIC (RNIC) for RoCE protocols. Converging both protocols to a single adapter reduces Z customers’ cost for physical networking resources. With this change, IBM Z customers can now exploit Shared Memory Communications (SMC) leveraging RDMA (SMC-R) technology without incurring additional hardware costs. In this session, the speakers will focus on how z/OS Communications Server has been updated to support the Network Express feature. An introduction to the new Enhanced QDIO Ethernet (EQENET) interface statement used to configure the new OSA is provided. EQDIO provides a variety of simplifications, such as no longer requiring VTAM user defined TRLEs, uses smarter defaults and removes outdated parameters. The speakers will also cover migration considerations for Network Express. In addition, the operational aspects of managing and monitoring the new OSA and RoCE interfaces will be covered. The speakers will also take you through the enhancements made to optimize both inbound and outbound network traffic. Come join us, step aboard and learn how z/OS Communications Server is bringing you the future in network communications with the IBM z17 Network Express feature.
