Introduction to Web 2.0 Technologies
Introduction to Web 2.0 Joshua Stern, Ph.D. Introduction to Web 2.0 Technologies What is Web 2.0? Æ A simple explanation of Web 2.0 (3 minute video): http://www.youtube.com/watch?v=0LzQIUANnHc&feature=related Æ A complex explanation of Web 2.0 (5 minute video): http://www.youtube.com/watch?v=nsa5ZTRJQ5w&feature=related Æ An interesting, fast-paced video about Web.2.0 (4:30 minute video): http://www.youtube.com/watch?v=NLlGopyXT_g Web 2.0 is a term that describes the changing trends in the use of World Wide Web technology and Web design that aim to enhance creativity, secure information sharing, increase collaboration, and improve the functionality of the Web as we know it (Web 1.0). These have led to the development and evolution of Web-based communities and hosted services, such as social-networking sites (i.e. Facebook, MySpace), video sharing sites (i.e. YouTube), wikis, blogs, etc. Although the term suggests a new version of the World Wide Web, it does not refer to any actual change in technical specifications, but rather to changes in the ways software developers and end- users utilize the Web. Web 2.0 is a catch-all term used to describe a variety of developments on the Web and a perceived shift in the way it is used. This shift can be characterized as the evolution of Web use from passive consumption of content to more active participation, creation and sharing. Web 2.0 Websites allow users to do more than just retrieve information. -
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.

Picasa Getting Started Guide
Picasa Getting Started Guide Picasa is free photo management software from Google that helps you find, edit and share your photos in seconds. We recommend that you print out this brief overview of Picasa's main features and consult it as you use the program for the first time to learn about new features quickly. Organize Once you start Picasa, it scans your hard drive to find and automatically organize all your photos. Picasa finds the following photo and movie file types: • Photo file types: JPG, GIF, TIF, PSD, PNG, BMP, RAW (including NEF and CRW). GIF and PNG files are not scanned by default, but you can enable them in the Tools > Options dialog. • Movie file types: MPG, AVI, ASF, WMV, MOV. If you are upgrading from an older version of Picasa, you will likely want to keep your existing database, which contains any organization and photo edits you have made. To transfer all this information, simply install Picasa without uninstalling Picasa already on your computer. On your first launch of Picasa you will be prompted to transfer your existing database. After this process is complete, you can uninstall Picasa. Library view Picasa automatically organizes all your photo and movie files into collections of folders inside its main Library view. Layout of main Library screen: Picasa Getting Started Guide Page 1 of 9 Folder list The left-hand list in Picasa's Library view shows all the folders containing photos on your computer and all the albums you've created in Picasa. These folders and albums are grouped into collections that are described in the next section.
