La Promotion Du Web Ouvert a Bien Changé Mais Mozilla Est Toujours Là
La promotion du Web Ouvert a bien changé mais Mozilla est toujours là Promouvoir le Web ouvert est l’une des missions de Mozilla. Mission parfaitement assumée et réussie il y a quelques années avec l’avènement de Firefox qui obligea Internet Explorer à quitter son arrogance pour rentrer dans le rang et se montrer plus respectueux des standards et donc des internautes. Sauf qu’aujourd’hui la donne a sensiblement changé. Avec la mobilité, les stores, les apps, les navigateurs intégrés, etc. c’est en effet un Web bien plus complexe qui se présente devant nous. Un Web enthousiasmant[1] mais plein d’embûches pour ceux qui sont attachés à son ouverture et à sa neutralité. C’est tout l’objet de ce très intéressant récent billet du développeur Mozilla Robert O’Callahan. Des changements dans la façon de promouvoir le Web Ouvert Shifts In Promoting The Open Web Robert O’Callahan – 30 septembre 201 – Blog personnel (Traduction Framalang : Antistress et Goofy) Historiquement Mozilla a dépensé pas mal d’énergie pour promouvoir l’usage du « Web ouvert » plutôt que de plateformes propriétaires et de code spécifique à des navigateurs non standards (IE6). Cette évangélisation reste nécessaire mais le paysage s’est modifié et je pense que notre discours doit s’adapter. Les plateformes dont nous devons nous préoccuper ont beaucoup changé. Au lieu de WPF, Slivertlight and Flash, les outils propriétaires pour développeurs avec lesquelles il faut rivaliser dorénavant sont iOS et Android. En conséquence, les fonctionnalités que le Web doit intégrer sont à présent orientées vers la mobilité. -

It can be almost anything you can hear or see. − Examples : Pictures, music, sound, videos, records, films, animations, and more. − Web pages often contain multimedia elements of different types and formats. • Multimedia Formats − Multimedia elements (like sounds or videos) are stored in media files. − The most common way to discover the type of a file, is to look at the file extension. ⇔ When a browser sees the file extension .htm or .html, it will treat the file as an HTML file. ⇔ The .xml extension indicates an XML file, and the .css extension indicates a style sheet file. ⇔ Pictures are recognized by extensions like .gif, .png and .jpg. − Multimedia files also have their own formats and different extensions like: .swf, .wav, .mp3, .mp4, .mpg, .wmv, and .avi.

An Introduction to AJAX
An Introduction to AJAX By : I. Moamin Abughazaleh Page 2 /25 How HTTP works? Classical HTTP Process 1. The visitor requests a page Page 3 /25 2. The server send the entire HTML, CSS and Javascript code at once to the client 3. So, the communication is synchronious Page 4 /25 What is Javascript programming actually? What is Javascript programming? It is programming the browsers. So, we are limited to the objects that the Page 5 /25 browser presents us An Alternative for Managing requests - AJAX AJAX stands for Asynchronous JavaScript And XML. AJAX is based on XMLHttpRequest object of Page 6 /25 Javascript - so the browser and XMLHttpRequest is a standard http://www.w3.org/TR/XMLHttpRequest/ It was introduced with IE-5.0 as an ActiveX object (1999) Later all the major browsers added XMLHttpRequest into their object bases. AJAX = Asynchronous JavaScript and XML It is a technique for creating better, faster, and more interactive web applications With XMLHttpRequest object JavaScript can trade data with a web server, without reloading Page 7 /25 the page AJAX uses “asynchronous data transfer” => allowing web pages to request small bits of information from the server instead of whole pages We can create desktop application like web applications using AJAX, this paradigm is also called “WEB 2.0” programming AJAX - Based on Web Standards AJAX is based on the following web standards: XHTML and CSS Presentation DOM Dynamic display of and interaction with data XML and XSLT Tranfering data back and forth Page 8 /25 XMLHttpRequest Asynchronous transfer of data Javascript Bring these technologies together AJAX applications are browser and platform independent The XMLHttpRequest object is supported in Internet Explorer 5.0+, Safari 1.2, Mozilla 1.0 / Firefox, Opera 8+, and Netscape 7. -

W3C liability, trademark, document use and software licensing rules apply. Abstract This document specifies the "Boston" version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL Boston has the following two design goals: ● Define a simple XML-based language that allows authors to write interactive multimedia presentations. Using SMIL Boston, an author can describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen. ● Allow reusing of SMIL syntax and semantics in other XML-based languages, in particular those who need to represent timing and synchronization. For example, SMIL Boston components should be used for integrating timing into XHTML. Status of this document This section describes the status of this document at the time of its publication. Other documents may supersede this document. The latest status of this document series is maintained at the W3C. This document is the first working draft of the specification for the next version of SMIL code-named "Boston". -

Progressive Imagery with Scalable Vector Graphics -..:: VCG Rostock
Progressive imagery with scalable vector graphics Georg Fuchsa, Heidrun Schumanna, and Ren´eRosenbaumb aUniversity of Rostock, Institute for Computer Science, 18051 Rostock, Germany; bUC Davis, Institute of Data Analysis & Visualization, Davis, CA 95616 U.S.A. ABSTRACT Vector graphics can be scaled without loss of quality, making them suitable for mobile image communication where a given graphics must be typically represented in high quality for a wide range of screen resolutions. One problem is that file size increases rapidly as content becomes more detailed, which can reduce response times and efficiency in mobile settings. Analog issues for large raster imagery have been overcome using progressive refinement schemes. Similar ideas have already been applied to vector graphics, but an implementation that is compliant to a major and widely adopted standard is still missing. In this publication we show how to provide progressive refinement schemes based on the extendable Scalable Vector Graphics (SVG) standard. We propose two strategies: decomposition of the original SVG and incremental transmission using (1) several linked files and (2) element-wise streaming of a single file. The publication discusses how both strategies are employed in mobile image communication scenarios where the user can interactively define RoIs for prioritized image communication, and reports initial results we obtained from a prototypically implemented client/server setup. Keywords: Progression, Progressive refinement, Scalable Vector Graphics, SVG, Mobile image communication 1. INTRODUCTION Vector graphics use graphic primitives such as points, lines, curves, and polygons to represent image contents. As those primitives are defined by means of geometric coordinates that are independent of actual pixel resolutions, vector graphics can be scaled without loss of quality.
