Domain Driven Design (DDD)
Domain Driven Design (DDD)Tom Kocjan Domain Driven Design (DDD) is a software design approach that focuses on modeling a domain accurately. It uses ubiquitous language, bounded contexts, and explicit domain models. The key aspects of DDD include developing a shared model with domain experts, separating concerns into bounded contexts, and iteratively refining domain models through close collaboration between technical and domain teams. DDD aims to produce software designs that are more aligned with the mental models of users and stakeholders in a complex domain.

What is Virtualization
What is VirtualizationIsrael Marcus Virtualization is a technique that separates a service from the underlying physical hardware. It allows multiple operating systems to run simultaneously on a single computer by decoupling the software from the hardware. There are two main approaches - hosted virtualization runs atop an operating system, while hypervisor-based virtualization installs directly on the hardware for better performance and scalability. A virtualization layer called a VMM manages and partitions CPU, memory, and I/O access for the guest operating systems. Virtualization overcomes the challenge that x86 operating systems assume sole ownership of the hardware through techniques like binary translation, para-virtualization with OS assistance, or newer hardware-assisted virtualization.

Introduction to virtualization
Introduction to virtualizationAhmad Hafeezi Virtualization allows for the creation of virtual versions of hardware platforms, operating systems, storage and network resources through software. It works by imitating hardware resources through a hypervisor software layer that creates virtual machines with virtual hardware. This allows multiple guest operating systems to run in isolation on a single physical machine. Virtualization provides benefits like reduced costs, increased hardware utilization, easier management and testing across different operating systems. Popular virtualization platforms include VMWare, Hyper-V, KVM, Xen and VirtualBox.

Virtualization
VirtualizationKumar Harsha Virtualization involves dividing the resources of a computer into multiple execution environments. It has been used since the 1960s and there are several types including hardware, desktop, and language virtualization. The key components of a virtualization architecture are the hypervisor and guest/host machines. Hypervisors allow multiple operating systems to run on a single system and can be type 1 (runs directly on hardware) or type 2 (runs within an operating system). Virtualization provides benefits but also has limitations related to resource allocation and compatibility that vendors continue working to address.

Title: Navigating HCL Notes 14 Upgrades: A Comprehensive Guide for Conquering Challenges
Abstract:
In this session Christoph Adler will guide you systematically through the intricate process of mastering every challenge encountered in an HCL Notes 14 Upgrade project. Numerous changes from 32 to 64-bit architecture necessitate careful consideration and resolution within the upgrade package itself. This includes tasks such as uninstallation (incl. nice.exe in 32- and 64-bit), cleanup procedures (addressing old program and shareddata folders and more), migration the data folder and the very important notes.ini file, and meticulous installation practices (sorting order, command lines, parsing logs, etc.).
The session will also delve into pre-configuration essentials for new users, covering elements like the common folder, stub notes.ini, config file and others to ensure a seamless onboarding process. Emphasizing the impact of changes in bitness and folder locations in Notes 14, the discussion will explore considerations for Anti-Virus, DEP, AppBlocker and Security Software, highlighting their potential as game-changers for end-user performance.
Having thoroughly examined the aforementioned aspects, the session will conclude with an objective and candid comparison of various Notes upgrade methods, enabling participants to make informed decisions tailored to their specific project requirements.

Why should a Java programmer shifts towards Functional Programming Paradigm
Why should a Java programmer shifts towards Functional Programming ParadigmTech Triveni Functional programming, a buzz word these days. Everyone is trying to learn it. A few functional programming languages are getting attraction and are getting used in the production too such as Scala, Haskell, Clojure and so on. And Even Java has already introduced a few concepts to support functional programming which are Lambdas, Functional Interfaces, Streams, etc. Now the question comes, why should a Java programmer needs to shift towards functional programming.
Java has a very big community and using imperative programming from the last 2 decades. It needs a very solid reason to shift towards the functional programming paradigm. The functional programming paradigm focuses on some key concepts like immutability, higher-order functions and so on and it has a moderate learning curve, but if we can get benefit out of it, then there is no harm in learning functional.
In this talk we will see, what are the benefits we get when we follow the functional programming paradigm in Java, how it makes the developer life easy. We will discuss the comparison between the imperative code vs functional code with some examples.
We will discuss the transition from imperative coding to functional coding with some code examples. This talk will be good for the people who really want to switch to functional programming and want to know how to use that in Java.
Asynchronous javascript
Asynchronous javascriptEman Mohamed This document discusses challenges with asynchronous JavaScript programming using callbacks and promises, and introduces several approaches to help address these challenges, including async/await, generators, reactive programming with Rx observables, and functional reactive programming with Cycle.js. It provides examples of callback hell and promise limitations. Functional reactive programming uses functional utilities like map and filter to automatically propagate changes through observable data streams. Cycle.js implements a functional reactive paradigm for building asynchronous apps in a simple, extensible, and testable way by containing side effects and making data flows explicit.

Effects, Coeffects & Subscriptions: a pit of success for SPAsManuel Rivero This document summarizes a talk about using effects, coeffects, and subscriptions to manage state and side effects in single-page applications built with ClojureScript and re-frame. It discusses how modeling event handlers as pure functions that return effects based on coeffects avoids accidental complexity. It also covers how modeling the user interface as finite state machines and using re-frame subscriptions can improve performance and simplify application structure. Finally, it notes how this approach allowed large code reuse between the browser and mobile versions of an application.
Eclipsecon 2010 - Scala Support in Eclipse
Eclipsecon 2010 - Scala Support in EclipseMiles Sabin The Scala IDE for Eclipse aims to provide Java-level tooling for Scala by modifying the Java Development Tools (JDT) using aspect-oriented programming. This allows features of the Java tooling to be made aware of Scala language elements. While initially successful, more collaboration is needed to fully integrate Scala and other JVM languages at the IDE level. The approach also risks the patched code diverging from Eclipse over time.
JVM Languages Support in Eclipse - Monkey-patching the JDT for fun and profit?
JVM Languages Support in Eclipse - Monkey-patching the JDT for fun and profit?Miles Sabin This document discusses efforts to integrate JVM languages like Scala into the Eclipse IDE. It describes how the Scala IDE for Eclipse used aspect-oriented programming (AOP) to "monkey-patch" the Java Development Tools (JDT) in order to expose APIs and allow languages besides Java to integrate. This approach has been used by Scala, Groovy, JavaFX, and other language tooling projects. More collaboration is needed to develop shared APIs and functionality to better support multiple JVM languages in Eclipse.

The Apollo and GraphQL Stack
The Apollo and GraphQL StackSashko Stubailo GraphQL is a wonderful abstraction for describing and querying data. Apollo is an ambitious project to help you build apps with GraphQL. In this talk, we'll go over how all the parts—Client, Server, Dev Tools, Codegen, and more—create an end-to-end experience for building apps on top of any data.
## Detailed description
In today's development ecosystem, there are tons of options for almost every part of your application development process: UI rendering, styling, server side rendering, build systems, type checking, databases, frontend data management, and more. However, there's one part of the stack that hasn't gotten as much love in the last decade, because it usually falls in the cracks between frontend and backend developers: Data fetching.
The most common way to load data in apps today is to use a REST API on the server and manage the data manually on the client. Whether you're using Redux, MobX, or something else, you're usually doing everything yourself—deciding when to load data, how to keep it fresh, updating the store after sending updates to the server, and more. But if you're trying to develop the best user experience for your app, all of that gets in the way; you shouldn't have to become a systems engineer to create a great frontend. The Apollo project is based on the belief that data loading doesn't have to be complicated; instead, you should be able to easily get the data you want, when you want it, and it should be managed for you just like React manages updating your UI.
Because data loading touches both the frontend and backend of your app, GraphQL and Apollo have to include many parts to fulfill that promise of being able to seamlessly connect your data together. First, we need client libraries not only for React and JavaScript, but also for native iOS and Android. Then, we must bring server-side support for GraphQL queries, mutations, and most recently subscriptions to every server technology and make those servers easier to write. And finally, we want not only all of the tools that people are used to with REST APIs, but many more thanks to all of the capabilities enabled by GraphQL.
In this talk, we'll go over all of the parts of a GraphQL-oriented app architecture, and how different GraphQL and Apollo technologies come together to solve all of the parts of data loading and management for React developers.
Unit testing legacy code
Unit testing legacy codeLars Thorup Unit testing and test-driven development are practices that makes it easy and efficient to create well-structured and well-working code. However, many software projects didn't create unit tests from the beginning.

Integrating Survey123 and R&H Data Using FME
Integrating Survey123 and R&H Data Using FMESafe Software West Virginia Department of Transportation (WVDOT) actively engages in several field data collection initiatives using Collector and Survey 123. A critical component for effective asset management and enhanced analytical capabilities is the integration of Geographic Information System (GIS) data with Linear Referencing System (LRS) data. Currently, RouteID and Measures are not captured in Survey 123. However, we can bridge this gap through FME Flow automation. When a survey is submitted through Survey 123 for ArcGIS Portal (10.8.1), it triggers FME Flow automation. This process uses a customized workbench that interacts with a modified version of Esri's Geometry to Measure API. The result is a JSON response that includes RouteID and Measures, which are then applied to the feature service record.
