The document summarizes the new features of GWT 2.0, an open source JavaScript compiler for Java. Key highlights include improved developer tools like Speed Tracer for profiling applications, declarative user interfaces through UiBinder, enhanced layout panels, client-side resource bundling via ClientBundle, and improved unit testing with HtmlUnit. GWT 2.0 also features optimizations to the compiler as well as code splitting capabilities for faster loading of large applications.
WebSockets allow for bidirectional communication between web browsers and servers. The presenter demonstrated WebSockets through a sample application and discussed browser support, the HTTP handshake process, and JavaScript and server-side APIs. WebSockets use ports 80 and 443 and an HTTP upgrade request to establish a persistent connection. Once connected, events like onopen, onmessage, and onclose enable asynchronous messaging between the client and server. Popular libraries provide WebSocket support for technologies like GWT, jQuery, Glassfish, and JBoss Netty.
The document discusses the digital revolution and how the pace of growth in connected devices and technologies is accelerating. It notes that the pace of growth used to be every five years but is now shorter than two years. People are increasingly connected to devices and devices are connecting to other devices. Examples mentioned include smart rackets, connected cars, and smart toothbrushes. The presentation then discusses partnerships and strategies for success in commerce and leveraging connected customers through brand elevation, mobile-first marketing, and intelligent inventory.
This document outlines terms and conditions for carriage services provided by Rapid Despatch logistics Ltd. It defines key terms like "Carrier" and "Customer" and outlines responsibilities of each party. The Carrier is not a common carrier and accepts consignments at its sole discretion. It may employ subcontractors but remains responsible as agent. The Customer warrants they are authorized to accept the terms. The document also specifies liability limitations, time limits for claims, and the Carrier's right to sell unclaimed goods to recover charges owed.
The document summarizes an English lesson plan for a secondary level class. It includes details about the class such as the date, time, number of students, and teaching objectives. The lesson plan focuses on revising jobs vocabulary and introducing plural verbs. Activities include flashcard exercises to practice jobs and verbs, reading an article about a band, and correcting sentences from the article. The class aims to develop reading, listening, and speaking skills through integrated tasks using the article.

DevNexus 2013 - Introduction to WebSocketsGunnar Hillert
The WebSockets technology promises to fill a niche in web applications by enabling browsers and servers to exchange messages with high frequency, low latency and low bandwith requirements in full duplex mode. The WebSocket protocol is an IETF standard, the WebSocket API is almost standardized by the W3C, and the JSR-356 will deliver a Java API in Java EE 7. There are already implementations in node.js and in a number of Servlet containers and Java frameworks. The time is as good as ever to start digging into it and there is so much to consider — from getting familiar with the protocol and the API, to sorting through the choices on the browser and on the server side, practical challenges with browser support and network issues, and so on. Furthermore, WebSockets offer a messaging-style architecture that’s in sharp contrast to the RESTful architectures that connect the web today, so learning where to draw the line will be essential.
This short document promotes creating presentations using Haiku Deck, a tool for making slideshows. It encourages the reader to get started making their own Haiku Deck presentation and sharing it on SlideShare. In just one sentence, it pitches the idea of using Haiku Deck to easily create engaging slideshows.
JSR 356 defines a Java API for WebSocket that allows for full-duplex communication between clients and servers over a single TCP connection. The API supports events for when the connection opens and closes, as well as sending and receiving messages. To use it, a developer creates an Endpoint class that handles events like OnOpen, OnClose, and OnMessage. They then create a dynamic web project with an HTML page containing form elements to send messages, and JavaScript code to open a WebSocket and send messages to the Endpoint for processing.

The document describes an app called Frood that helps college students find campus events with free food. It discusses the problems of high tuition costs, lack of event attendees, and food waste at events. The story of a student, Zac, is presented who struggles to find information about free food events. The story of an event organizer, Catherine, is also shared who wants to promote her events better to increase attendance and reduce leftover food. The document proposes that Frood could solve both these problems by serving as a centralized platform for students to discover free food events and organizers to advertise their events.

Este documento trata sobre psicrometría, que estudia las mezclas de gases ideales con vapor de agua. Explica conceptos como humedad específica, humedad relativa, temperatura de bulbo seco y húmedo, y procesos de acondicionamiento de aire como calentamiento, enfriamiento, deshumidificación y humidificación. También describe torres de enfriamiento, que utilizan la evaporación del agua para reducir su temperatura.
Este documento describe las políticas de mantenimiento de una institución en Venezuela. Explica los principios de organización del mantenimiento, incluyendo la especialización, jerarquía y coordinación. También cubre el tamaño de las empresas, la ubicación, los tipos de mantenimiento, y cómo se definen, controlan y evalúan las políticas de mantenimiento. El documento concluye que el mantenimiento representa una inversión a largo plazo que genera ahorros a través de mejoras en la producción y seguridad laboral.
El documento describe cómo la actividad humana ha afectado negativamente el equilibrio ecológico desde la aparición del hombre en la Tierra, empeorando considerablemente a partir de la revolución industrial con un aumento de la contaminación. También explica cómo el hombre depende de los recursos naturales y cómo sus actividades como la industria y la explotación petrolera han impactado el medio ambiente.
A biosensor is a device that uses biological reactions like enzymes to detect chemicals in biological samples. It integrates a biological component like an enzyme with a sensor to produce an electronic signal proportional to the analyte being measured. Key characteristics of biosensors include linearity, sensitivity, selectivity, and response time. There are different types including calorimetric, potentiometric, amperometric, and optical biosensors. Biosensors have applications in food analysis, medical diagnosis, environmental monitoring, quality control, and more. Examples include pregnancy tests that detect hCG protein and glucose monitors that detect blood glucose levels.
WebSocket is a protocol that provides full-duplex communication channels over a single TCP connection. It was standardized in 2011 and allows for real-time data exchange between a client and server. The document discusses how WebSocket works, compares it to previous techniques like polling which had limitations, and outlines how to implement WebSocket in Java using JSR 356 and in Spring using the WebSocket API and STOMP protocol.
