Preview Dart Programming Tutorial
Dart Programming About the Tutorial Dart is an open-source general-purpose programming language. It is originally developed by Google and later approved as a standard by ECMA. Dart is a new programming language meant for the server as well as the browser. Introduced by Google, the Dart SDK ships with its compiler – the Dart VM. The SDK also includes a utility -dart2js, a transpiler that generates JavaScript equivalent of a Dart Script. This tutorial provides a basic level understanding of the Dart programming language. Audience This tutorial will be quite helpful for all those developers who want to develop single-page web applications using Dart. It is meant for programmers with a strong hold on object- oriented concepts. Prerequisites The tutorial assumes that the readers have adequate exposure to object-oriented programming concepts. If you have worked on JavaScript, then it will help you further to grasp the concepts of Dart quickly. Copyright & Disclaimer © Copyright 2017 by Tutorials Point (I) Pvt. Ltd.

What Is Dart?
1 Dart in Action By Chris Buckett As a language on its own, Dart might be just another language, but when you take into account the whole Dart ecosystem, Dart represents an exciting prospect in the world of web development. In this green paper based on Dart in Action, author Chris Buckett explains how Dart, with its ability to either run natively or be converted to JavaScript and coupled with HTML5 is an ideal solution for building web applications that do not need external plugins to provide all the features. You may also be interested in… What is Dart? The quick answer to the question of what Dart is that it is an open-source structured programming language for creating complex browser based web applications. You can run applications created in Dart by either using a browser that directly supports Dart code, or by converting your Dart code to JavaScript (which happens seamlessly). It is class based, optionally typed, and single threaded (but supports multiple threads through a mechanism called isolates) and has a familiar syntax. In addition to running in browsers, you can also run Dart code on the server, hosted in the Dart virtual machine. The language itself is very similar to Java, C#, and JavaScript. One of the primary goals of the Dart developers is that the language seems familiar. This is a tiny dart script: main() { #A var d = “Dart”; #B String w = “World”; #C print(“Hello ${d} ${w}”); #D } #A Single entry point function main() executes when the script is fully loaded #B Optional typing (no type specified) #C Static typing (String type specified) #D Outputs “Hello Dart World” to the browser console or stdout This script can be embedded within <script type=“application/dart”> tags and run in the Dartium experimental browser, converted to JavaScript using the Frog tool and run in all modern browsers, or saved to a .dart file and run directly on the server using the dart virtual machine executable. -

Natickfoss Online Meetings Page 1 of 4
NatickFOSS Online Meetings Page 1 of 4 During April and perhaps beyond, meetings at the Community/Senior Center are not possible. We are going to try to provide an online live meeting alternative. TO VIEW the meeting live at 3PM or at later date, use a browser for YouTube. It’s that simple! For April 2nd the link is: https://www.youtube.com/watch?v=C8ZTmk4uXH4 -------------------------Do not try to view and participate at the same time!--------------------- TO PARTICIPATE: We will use a service called Jitsi Meet. It is open source and runs in a browser. Use open source Chromium browser which is our choice. Or use Chrome, the commercial version from Google, also works fine. We are sad to report that Firefox performs worse. It is less stable at this time. (DO NOT USE Firefox for our Meetings, please!) We want to avoid problems. Linux users can install Chromium from their distribution’s software repositories. Windows: probably best to use Chrome unless you are adventurous. Edge does not work at this time. Macintosh: install Chrome, please. We have heard Safari does not work. Once your browser is installed, launch it and enter (copy from here, paste in browser) this link: https://meet.jit.si/natickfoss ...or just use any browser to go to the YouTube channel to just watch. The first time you use Chromium or Chrome with Jitsi Meet you will be asked if you want to install an extension. The extension is optional. We will NOT need the features for our meetings. Just close if you want. -
Cliente Twitter Con Compresión De Datos
PROYECTO FIN DE GRADO GRADO EN INGENIERÍA INFROMÁTICA CLIENTE TWITTER CON COMPRESIÓN DE DATOS Autor: Plácido Fernández Declara Tutores: Luis Miguel Sánchez García Rafael Sotomayor Fernández Colmenarejo, Febrero de 2013 RESUMEN La popular red social Twitter es usada hoy en día en diversos lugares y momentos, gracias también a las redes móviles que nos proporcionan conexión a internet en casi cualquier lugar. Twitter permite publicar y mandar mensajes cortos de texto plano con un máximo de 140 caracteres, así como la lectura de estos mensajes cortos de otros usuarios a los que podemos seguir para tal propósito. Hacer uso de este servicio en zonas con buena cobertura, o cuando usamos Wi-fi no supone generalmente ningún problema. Es cuando nos encontramos en zonas de poca cobertura cuando vemos problemas para hacer uso de este servicio, ya que las velocidades de descarga pueden disminuir hasta el punto de necesitar decenas de segundos para disponer de los mensajes cortos, los “Tweets”. A esto hay que añadir que los planes de datos actuales están limitados de alguna forma (al alcanzar un número de Mb), por lo que la cantidad de Mb usada es hoy también un factor importante. Para ello esta aplicación ofrece la experiencia de un cliente Twitter sencillo en el que consultar los “Tweets” de a quien seguimos, así como publicar “Tweets”, haciendo uso de un Proxy que comprime estos datos considerablemente de forma que se reducen los tiempos de descarga para las zonas de poca cobertura y además se reduce el número de Mb consumidos por el dispositivo móvil.

Google Webtool
Google Web Toolkit Stephen Bilston Stuart Johnson Eric Fath-Kolmes Ai Ci Lin Andrew Nisbet Presentation Goals What is GWT? An overview of GWT's features. When should I use GWT? Who's using it? Finally what you can do with it? What are the risks? What is Google Web Toolkit (GWT)? Develop Webapps using Java Compile the Java to X-browser Javascript Finally a magic bullet to fix Everything! What's so great about it Abstracts away HTML and CSS Makes Client server communcation easy Has robust 3rd party libaraies Easy deployment Eases Web development Lets you avoid HTML and CSS along with all there vairous oddities Many programmers already know java but don't know JavaScript, GWT moves the task of learning from new languages to what is effectively another library Writing javascript can be weird - GWT removes much of the weirdness Makes client server comuncation easy Two easy methods: GWT-RPC Almost makes server commuincation feel like local method calls Has rather good serialization functionality Request Factory Acts like a fake ORM(Object Relational Mapping) for the client side Normal Ajax if you really want to Has robust third party libaries Smart GWT Widgets Dual licensed Ext GWT More Widgets Dual licensed with reduced functionaliy Vaadin Widgets Server Side functionality(validation, etc) Easy depoyment Uses Java Servlets for GWT-RPC and Request Factory Lots of options(Tomcat, JBoss etc..) If your okay with the abstraction leaking a bit you can use anything to do generic AJAX Php Ruby Perl Whatever Using java server side is an easy sell Code Quality Concerns Debugging -With GWT, you can debug java byte code directly as it was executed in a simulated browser environment.
