Spring Boot & WebSocket presentation covers:
1. An introduction to Spring Boot and its advantages over traditional Spring configurations. Spring Boot aims to provide a faster development experience with less configuration.
2. Examples of integrating common features into Spring Boot applications like Tomcat, JSP, MySQL, security, and logging. Spring Boot plugins simplify adding these features.
3. A demonstration of using WebSocket, SockJS, and STOMP with Spring Boot for real-time client-server communication. Server-side configurations and client-side JavaScript/Java code are shown.
4. Sequence diagrams illustrate use cases for WebSocket with SockJS and STOMP to send messages to subscribers from the server and between clients.

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.
Welcome to presentation on Spring boot which is really great and relatively a new project from Spring.io. Its aim is to simplify creating new spring framework based projects and unify their configurations by applying some conventions. This convention over configuration is already successfully applied in so called modern web based frameworks like Grails, Django, Play framework, Rails etc.
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.
This is covered during the tech conference. It covers high-level security. The best practice for deployment for gateway (what was known as last-mile) is covered at the end.
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

• Spring framework
• Inversion of Control
• Dependency Injection – Two types
• Defining beans using XML
• Inheriting beans

Building an enterprise level single sign-on application with the help of keycloak (Open Source Identity and Access Management).
And understanding the way to secure your application; frontend & backend API’s. Managing user federation with minimum configuration.
Presentation explain about
Spring Boot vs Spring vs Spring MVC,
Advantages,
Where to start and how does Spring boot work ?,
Dependency Management,
Logging,
Exception Handling,
Database Handling.
in Spring boot.
Comet approaches overview, benefits and drawbacks: polling, long-polling, HTML5 server-side events, HTML5 WebSocket.
Example of WebSocket and Spring 4 integration using STOMP protocol.
SockJS is a browser JavaScript library that provides a WebSocket-like object. It gives a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server.
Under the hood SockJS tries to use native WebSockets first.
SockJS is intended to work for all modern browsers and in environments which don't support the WebSocket protocol. In this slide a real time chat application using SockJS (sockjs-1.1.1.min.js as SockJS-client, SockJS-node as SockJS-server) step by step development is also shown.

Dynamic Apps with WebSockets and MQTT - IBM Impact 2014Bryan Boyd

Consuming web services asynchronously with Futures and Rx Observables (svcc, ...Chris Richardson
A modular, polyglot architecture has many advantages but it also adds complexity since each incoming request typically fans out to multiple distributed services. For example, in an online store application the information on a product details page - description, price, recommendations, etc - comes from numerous services. To minimize response time and improve scalability, these services must be invoked concurrently. However, traditional concurrency mechanisms are low-level, painful to use and error-prone. In this talk you will learn about some powerful yet easy to use abstractions for consuming web services asynchronously. We will compare the various implementations of futures that are available in Java, Scala and JavaScript. You will learn how to use reactive observables, which are asynchronous data streams, to access web services from both Java and JavaScript. We will describe how these mechanisms let you write asynchronous code in a very straightforward, declarative fashion.

Testing Spring MVC and REST Web ApplicationsSam Brannen
The Spring Team has innovated extensively around testing in the past, and this innovation continues today. One of the most exciting recent additions to Spring's testing support is Spring MVC Test. What makes it so interesting is the comprehensive support for testing web applications and context hierarchies with the Spring TestContext Framework as well as comprehensive support for out-of-container Spring MVC and REST integration testing.
Join core Spring Framework committer Sam Brannen to see these new Spring Web testing features in action and learn how to speed up your development-test lifecycle.

A Java servlet is a Java program that extends the capabilities of a server. Although servlets can respond to any types of requests, they most commonly implement applications hosted on Web servers. Such Web servlets are the Java counterpart to other dynamic Web content technologies such as PHP and ASP.NET.
Vaccine management system project report documentation..pdfKamal Acharya
The Division of Vaccine and Immunization is facing increasing difficulty monitoring vaccines and other commodities distribution once they have been distributed from the national stores. With the introduction of new vaccines, more challenges have been anticipated with this additions posing serious threat to the already over strained vaccine supply chain system in Kenya.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Quality defects in TMT Bars, Possible causes and Potential Solutions.PrashantGoswami42
Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.
