This document discusses data binding in Angular, including the differences between HTML attributes and DOM properties, the three types of data binding (one way and two way), and examples of each type of binding. It explains that one way binding can update properties, classes, styles, attributes and listen to events, but not read values. Two way binding uses the NgModel directive to both display and update a data property when the view changes. The document provides examples of property, event, class, style and attribute binding and how Angular matches bindings to component properties and events.
Spring - Part 2 - Autowiring, Annotations, Java based Configuration - slidesHitesh-Java
This document provides an overview of Spring autowiring and annotation-based configuration. It discusses the different autowiring modes including byName, byType, and constructor. It also covers key annotations like @Autowired, @Qualifier, and @Required. The document explains how to enable annotation-based configuration in Spring and examples of using annotations on setter methods, constructors, and properties. Finally, it introduces Java-based Spring configuration using @Configuration and @Bean along with topics that will be covered in the next session on Spring AOP.
This document provides an overview of Spring Boot and some of its key features. It discusses the origins and modules of Spring, how Spring Boot simplifies configuration and dependency management. It then covers examples of building Spring Boot applications that connect to a SQL database, use RabbitMQ for messaging, and schedule and run asynchronous tasks.
This talk introduces Spring's REST stack - Spring MVC, Spring HATEOAS, Spring Data REST, Spring Security OAuth and Spring Social - while refining an API to move higher up the Richardson maturity model
This is a basic tutorial on Spring core.
Best viewed when animations and transitions are supported, e.g., view in MS Powerpoint. So, please try to view it with animation else the main purpose of this presentation will be defeated.
The document discusses the SOLID principles of object-oriented design, which are Single Responsibility Principle, Open Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. For each principle, it provides an example of how to apply the principle correctly and how violations of the principle can occur if it is not followed. It also lists some recommended reading materials on software design patterns and principles.
Hibernate is an object-relational mapping tool that allows Java objects to be persisted to a relational database. It provides transparent persistence by handling all database operations like insert, update, delete, and retrieval. Hibernate sits between the Java application and database, mapping objects to database tables and allowing developers to work with objects rather than directly with SQL statements. Configuration files define the mappings between Java classes and database tables. Hibernate uses these mappings to automatically generate SQL to load and store objects.
Spring Boot is a framework for creating stand-alone, production-grade Spring based applications that can be "just run". It takes an opinionated view of the Spring platform and third-party libraries so that new and existing Spring developers can quickly get started with minimal configuration. Spring Boot aims to get developers up and running as quickly as possible with features like embedded HTTP servers, automatic configuration, and opinions on structure and dependencies.

SOLID Design Principles applied in Java: rules to develop scalable and easily maintainable code
Speaker: Ionut Bilica - Senior Software Developer @ Luxoft Romania.
During this talk we will discuss about the SOLID Principles described by Robert C. Martin, applying them in the Java programming language. Each principle will be explained in detail, with practical Java examples.
We will asses how these principles make it easy to develop the software for the entire duration of the project, and how some problems can appear if these principles are not applied. We will present common code fragments that do not respect these principles, and we'll see how we can correct them. Taking the SOLID principles into consideration, we will also analyse a real Java project using a Static Code Analyzer tool (e.g. STAN).
Finally, we will discuss the strategies on how to apply these design principles in "greenfield" projects, as well as "legacy" projects, while offering some tips and tricks.
The document provides information about HTML forms and JavaScript. It includes examples of HTML form fields like text, password, checkbox, radio buttons, and submit buttons. It also discusses how JavaScript can be used to validate form data, submit forms, and perform calculations. The last part discusses AJAX and how JavaScript and XMLHttpRequest object can be used to make asynchronous calls to retrieve and display data without reloading the page.
Spring Data is a high level SpringSource project whose purpose is to unify and ease the access to different kinds of persistence stores, both relational database systems and NoSQL data stores.
This document provides an introduction and overview of the Java 8 Stream API. It discusses key concepts like sources of streams, intermediate operations that process stream elements, and terminal operations that return results. Examples are provided to demonstrate filtering, sorting, mapping and collecting stream elements. The document emphasizes that streams are lazy, allow pipelining operations, and internally iterate over source elements.
Interfaces in Java declare methods but do not provide method implementations. A class can implement multiple interfaces but extend only one class. Interfaces are used to define common behaviors for unrelated classes and allow classes to assume multiple roles. Nested interfaces group related interfaces and must be accessed through the outer interface or class.
Lambda expressions, default methods in interfaces, and the new date/time API are among the major new features in Java 8. Lambda expressions allow for functional-style programming by treating functionality as a method argument or anonymous implementation. Default methods add new capabilities to interfaces while maintaining backwards compatibility. The date/time API improves on the old Calendar and Date APIs by providing immutable and easier to use classes like LocalDate.
Pseudo-classes are used to define special states of CSS elements. They allow styling elements when a user mouses over, focuses on, visits, or activates them. Common pseudo-classes include :hover, :focus, :visited, and :active. Pseudo-classes can be used with CSS classes and selectors like :first-child to style specific elements, such as styling the first <p> element or changing the color of a link on hover. Pseudo-elements like ::before and ::after allow inserting content before or after elements.
This document provides an overview of the Django web framework. It discusses what Django is, how to install and create a Django project and app. It also covers Django's MVT architecture, model definitions, templates, views, URLs and common tags used in templates. Key topics covered include installing Django, generating a project and app, model definitions, template usage, URL mapping and parameters, the admin interface, forms, and sessions. The document serves as a tutorial for getting started with basic Django development.
Spring Boot is a framework for creating stand-alone, production-grade Spring-based applications that can be started using java -jar without requiring any traditional application servers. It is designed to get developers up and running as quickly as possible with minimal configuration. Some key features of Spring Boot include automatic configuration, starter dependencies to simplify dependency management, embedded HTTP servers, security, metrics, health checks and externalized configuration. The document then provides examples of building a basic RESTful web service with Spring Boot using common HTTP methods like GET, POST, PUT, DELETE and handling requests and responses.
This document provides an overview of Java basics including:
- Java is an object-oriented programming language like C++.
- The basic unit in Java is the object, which contains both state in the form of variables and behavior in the form of methods.
- Classes define the structure and behavior of objects through methods and variables. The main method is required to execute a Java program.
The document discusses implementing Clean Architecture on Android apps. It describes challenges with traditional architectures like MVP where business logic is mixed with views. Clean Architecture separates concerns into layers - presentation, domain, and data. This makes apps easier to understand, maintain, and test. The domain and presentation layers are independent of frameworks, allowing flexibility. Testing can target each layer individually using tools like Espresso, JUnit, and Mockito. Overall Clean Architecture improves testability and decouples the codebase.
As of Java 8, the interfaces we define can include implemented methods (in addition to the abstract ones). These methods are known as default methods. The default methods assist us with the development of a flexible, modular and readable code. Their use extends beyond the backward compatibility maintenance in Java’s standard libraries.
As of Java 9, the interface we define can include the definition of private methods (in addition to the abstract ones and the implemented ones we can define as of Java 8). These private methods assist us with implementing the default ones.
This meetup will be dedicated to Java 8 default methods and to Java 9 private methods, as well as to a detailed overview of all aspects related to the use of interfaces in our code.

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.

The document discusses best practices for exception handling in Java applications. It recommends that exceptions should only be used for exceptional situations, be properly logged, and result in appropriate error responses. Business exceptions should be thrown for invalid user behavior, while technical exceptions occurring internally should be wrapped in business exceptions. Exceptions should have clear, descriptive names and result in the proper HTTP status codes. The document also provides examples of implementing localized exceptions, handling exceptions globally or at the controller level, and using SLF4J with Logback for logging.
The java persistence API provides a specification for persisting, reading, and managing data from your java object to your relational tables in the database. JPA specifies the set of rules and guidelines for developing interfaces that follow standards.
The document provides information on object-oriented programming concepts like classes, objects, encapsulation, inheritance and polymorphism. It discusses Java primitive data types like boolean, char, byte etc. It also covers defining custom classes with attributes and methods, creating objects, constructors, access modifiers, inheritance and polymorphism. The key concepts of OOP like encapsulation, inheritance and polymorphism are explained with examples.

Desde que empecé con Linux hace años, la consola, los scripts y yo nos hemos ido conociendo poco a poco hasta que ha surgido una bonita amistad. Hoy, en cuanto me surge la oportunidad juego con ellos para automatizar casi cualquier cosa de mi sistema operativo.
En esta charla quiero enseñar a programar scripts de Bash desde cero e ir subiendo la complejidad para terminar con AWK.
Originalmente es un taller que presenté en el t3chfest y que tuvo muy buena acogida, y que para el CommitConf he reducido y reestructurado como charla para que los que vengáis aprendáis los conceptos básicos de Bash y de AWK.

JHipster es un generador de código basado en Yeoman que nos genera un proyecto con Spring Boot en el back-end y con Angular en el front-end.
Llevo un año y medio desarrollando con Spring Boot y Angular y desde hace unos meses, mis nuevos desarrollos los realizo con JHipster. Por eso me he decidido a proponer este taller en donde montaré una pequeña aplicación con este tándem, y en donde hablaré también de mi propia experiencia.
Para poder asistir al taller es necesario tener instalado JHipster y tu IDE favorito (yo usaré Spring Tool Suite para back y Visual Studio Code para front). Para no tener problemas de descarga durante el taller tenéis que crearos un proyecto vacío, en el cual haremos modificaciones durante el taller. Creároslo con los valores por defecto, y luego ejecutarlo con ./mvnw para que se descarguen todas las librerías. Deberíais poder ver algo en http://localhost:8080 ;)
El documento resume la historia del software libre desde 1961 hasta 2017, destacando hitos como el nacimiento del concepto de hacker en el MIT en los 60, la creación de GNU por Richard Stallman en los 80 para tener un sistema operativo completamente libre, el lanzamiento de Linux por Linus Torvalds en 1991, el nacimiento de proyectos como Wikipedia, Arduino y Bitcoin, y cómo el software libre se ha convertido en una parte fundamental de la tecnología moderna que ha impulsado innovaciones en muchos campos.
En los años 70, en el MIT, los primeros hackers compartían sus códigos, como los chefs comparten sus recetas. Uno de esos hackers, Richard Stallman, creó en los 80 la Free Software Foundation. Desde entonces el movimiento del Software Libre no ha parado de crecer, invadiendo no solo los ámbitos informáticos, sino extendiéndose al resto de la sociedad. En esta charla quiero hablar de la historia del Software Libre: como surgió, personas destacadas, y cómo poco a poco ha ido expandiéndose. Hablaré de las distintas licencias de Software Libre, sus similitudes y sus diferencias. Pero también hablaré de las licencias Creative Commons, del movimiento Open Hardware y del moviemiento Open Data. Hablaré de cómo puedes colaborar con estos movimientos, y por qué es bueno para tí, para tu carrera profesional y para la sociedad. Terminaré haciendo una reflexión de cómo podría llegar a ser el futuro si la revolución del Software Libre sigue su progresión.
Después de participar en un montón de hackathones como participantes, y después de haber co-organizado más de 20 hackathones, nos gustaría compartir con vosotros todo nuestro conocimiento sobre hackathones, ya sea como participante pero sobre todo como organizador.
Este documento presenta las instrucciones y la agenda para un hackathon. Se explica que los participantes formarán equipos para desarrollar proyectos, se recomienda el uso de APIs y plataformas en la nube, y se especifican los requisitos para la presentación y entrega de los proyectos al final del evento. El objetivo es que los participantes aprendan, se conozcan entre sí y disfruten del proceso de creación colaborativa.
El documento presenta una charla sobre la historia y filosofía de los hackers, comenzando con la definición original de "hacker" como una persona entusiasta y curiosa que programa por placer y comparte su conocimiento. Explica cómo los primeros hackers del MIT desarrollaron el primer videojuego interactivo y compartían código de forma abierta, y cómo esto llevó al nacimiento del movimiento de software libre impulsado por Richard Stallman y la Free Software Foundation. Finalmente, describe cómo la ética hacker de compartir información se ha extendido a otros campos como
