XML
What is XML?
XML is the standard Extensible Markup Language. XML is a metalanguage that defines the syntax used to define other languages labels structured. Its purpose is to help the sharing of information from different systems.
Objectives
* XML must be compatible with SGML.
* It should be easy to write programs that process XML documents.
* The number of optional features in XML must be minimum, ideally zero.
Advantages
The XML pretends to be more suitable for the browsers and easier to use than the HTML, which has always cause problems. The main advantages that the XML language includes are:
- It’s performance is simple and compatible with much aplications.
- Allows you using different languages at the same time.
- You can be sure that you are not having sintaxic errors.
The importances and consequences
As IBM Systems Journal says XML has become the predominant mechanism for electronic data interchange between information systems and can be described as a universally applicable, durable “Code of Integration.”
As we celebrate its tenth anniversary, it is appropriate to reflect on the role XML has played and the technical ecosystem in which it functions. In this paper, we discuss both the environment from which XML arose and its technical underpinnings, and we relate these topics to companion papers in this issue of the IBM Systems Journal.
We discuss the broad consequences of XML and argue that XML will take its place among the technical standards having the greatest impact on the world in which we live. We conclude with some reflections on the significant technical, economic, and societal consequences that XML is likely to have in the future.

WEB 2.0
The concept of “Web 2.0″ began with a conference brainstorming session between O’Reilly and MediaLive International. Dale Dougherty, web pioneer and O’Reilly VP, noted that far from having “crashed”, the web was more important than ever, with exciting new applications and sites popping up with surprising regularity. What’s more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dot-com collapse marked some kind of turning point for the web, such that a call to action such as “Web 2.0″ might make sense? We agreed that it did, and so the Web 2.0 Conference was born.
In the year and a half since, the term “Web 2.0″ has clearlytaken hold, with more than 9.5 million citations in Google. But there’s still a huge amount of disagreement about just what Web 2.0 means, with some people decrying it as a meaningless marketing buzzword, and others accepting it as the new conventional wisdom.
The Web As Platform
Like many important concepts, Web 2.0 doesn’t have a hard boundary, but rather, a gravitational core. You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core.

Anuncios por Navidad
Aprovechando que ya llegan las vacaciones de Navidad. Se me plantean una serie de cuestiones respecto a la publicidad de estas épocas.No son pocas las firmas de ropa, perfumes o incluso turrones que aprovechando el tirón navideño nos sumergen en un mundo de fantasía a través de sus anuncios.Unos anuncios que a pesar de ser eso, fantasía; nos llenan de emociones, nostalgia e ilusiones para un nuevo año que comienza.
Los tiempos cambian y con ellos, ¿no debería cambiar también la publicidad?. Y si esto es así, si la publicidad cambia para todos menos para mí. ¿ no sabemos ya que todos los años El Almendro vuelve a casa por navidad? o que en pleno invierno, los niños de Antiu Xixona no deberían de estar descalzos sobre la nieve. ¿Y que opinaís del anuncio de busco a Jacqs? ¿realmente lo está buscando o es una excusa superflua para enseñar el escote?.
Por suerte o por desgracia siempre nos quedará el glamour de los anuncios de Freixenet o los anuncios de grandes estrellas de Hollywood que aprovechan sus atributos para vender fragancias, que aunque no creo que aumenten las ventas, por lo menos nos alegran la vista.
Aquí unos ejemplos
Oralidad, escritura e hipermedios
ORALITY
Walter Ong, distinguishes between two types: primary and secondary. The primary use oral cultures who do not know the write, while the secondary employ those who are already familiar with the later two forms of expression -written and orally language- as well as with new ones such as the telephone, television or radio.
- Additive/Paratactic
- Aggregative
- Redundant
- Conservative(Traditional)
- Close to the Human Lifeworld
- Agonistically Toned
- Empathetic and Participatory–Rhetorical
- Homeostatic
- Situational
LITERACY
As wikipedia says Ong describes writing as a technology that must be laboriously learned, and which effects the first transformation of human thought from the world of sound to the world of sight.
- Subordinate/Hypotactic (but…because)
- Analytic
- Linear
- Experimental
- Abstract
- Disengaged, Objectively Toned
- Philosophical
- Dynamic

DIGITALLY
Electronic communication changes the flow of information and knowledge, acting on the following points:
- -The interaction of the receptor with information -The time interaction -The structure of the message -Expand the size of communication
- Electronics.
- Computer Interaction.
- Realtime = immediately.
- Integrated Networks.
- Magnetic Memories.
- Many for many.
- Hipertextual with different kinds of language.
- Interactive.
- Multidirectional.

An E-book
An e-book (electronic book) is a digital device that has the same purpose than the convencional books, but it includes accesories which you can not enjoy with the printed ones.
What are the advantages of a digital book?
First of all, the possibility of achieving a comfortable and enjoyable reading where you can also carry an entire library contained there in. Different models of e-Book have been skilled to facilitate this activity: they are portable, and they have developed so much that nowadays they are similar in size and shape to the convencional books.
Their various applications allow you to perform multiple functions such as:
- Search text throughout the book.
- You have a system of menus to mark pages, underline and adjust the size of the words or its presentation.
- Add notes.
- Store a large number of works. (from 4000 to 100000 pages).
- Moving from one page to another just by giving a click or through a words locator.
Unfortunately there are also some disadvantages:
- Less control over standards. The publishing process of the normal books is hard, so it produces qualified products.
- Less control over author’s rights.
- They are shightly harder to read.
How to save an e-book
The electronic books can be read directly from the computer or be unloaded on the same one. In both cases, he will need to have installed someone of the following programs: “Microsoft Reader” or “Adobe Acrobat eBook Reader”.
- If the books in the way of ” MS Reader ” are not loaded with automatic form on having punctured on them, the book comes out into the computer with the straight button of the mouse by the option ” Guardar destino como “. You have to locate the file on the hard disk and open it with a double click.
- On the other hand, the books in the way of PDF are visualized by fault with the “Acrobat Reader”. If what you wish is to incorporate the book into your library “eBook”, continue like with the books in format ” MS Reader ” and download it on the hard disk. Later, open the book from the Adobe Acrobat eBook Reader
Novedades: ¡Se venden libros digitales!
Los nuevos tiempos y el modo de vida informatizado ha hecho que tanto las nuevas creaciones como objetos de la antigüedad se vayan adaptando a una sociedad cambiante, en el que las nuevas tecnologías son ya parte esnecial en nuestras vidas.Con todos estos cambios llama la atención, las innovaciones en elementos antiguos como ocurre con los libros que su evolución ya no sólo consiste en la portada(tapa dura o tapa blanda) sino en el propio formato del libro.
Actualmente, tenemos la oportunidad de disfrutar de grandes obras en un formato digital que es denominado e-book:
Un e-book, eBook, ecolibro, o libro-e es una versión electrónica o digital de un libro. El término es ambiguo, ya que se refiere tanto a una obra individual en formato digital, como a un dispositivo utilizado para leer libros en formato digital. La mayoría de los usuarios no utiliza el término eBook en el segundo sentido, y emplean, en cambio, el término más preciso de dispositivo de eBook.
Por otra parte, algunos autores defienden que se debe hacer una distinción entre los libros electrónicos y el hipertexto. El hipertexto, está destinado a la estructuración de la información a través de enlaces, mientras que un eBook no es más que la digitalización de un libro originariamente editado en papel. Un ejemplo de hipertexto sería la Wikipedia y uno de eBook cualquier libro en formato digital que pueda encontrarse en Internet o CD-ROM.wikipedia
La comunicación en la Web
La comunicación ha sido una constante desde tiempos ancestrales. En este campo de la ciencia es palpable la evolución acontecida, desde el primer télefono, creado por Antonio Meucci (no por Graham Bell para sorpresa de muchos) hasta las nuevas tecnologías de hoy; y es en este último aspecto en el que centro mi artículo. Las nuevas tecnologías han propiciado una comunicación impersonal pero muy adaptada a los nuevos tiempos en los que la temporalidad guía nuestras vidas. Dentro de estos nuevos medios encontramos por ejemplo:los foros.
En Internet son también conocidos como foros de mensajes, de opinión o foros de discusión y son una aplicación web que le da soporte a discusiones u opiniones en línea. (fuente Wikipedia)
