| What is Web2.0 about? | |
 |
Web2.0 is a technology
concept and language-neutral interface... Like many important concepts, Web2.0 doesn't
have a hard boundary. What was considered before as "Packaged Software", now
should be provided as a "Web Page", more precisely: as Web Information Services.
Web2.0 core is about API (Advanced Application Programming Interface), DOM (Document
Object Model), AJAX (XMLHTTP, Asynchronous JavaScript and XML technology), CSS (Cascading
Style Sheets language), HTML (Hypertext Markup Language), DHTML (Dynamic HTML), SGML
(Standard Generalized Markup Language), XML (subset of SGML)... API and DOM are platforms (language-neutral interface that allow programs and scripts to dynamically access and update the content, structure or style of documents)... the rest are meta-languages used to describe other languages and that is from where they get their attribute of "extensibility"... |
| Why is JavaScript so important? | |
 |
JavaScript is very powerful language that allows us to access and coordinate available Web2.0 features and control the document. JavaScript is a mini version of Java programming language, so simplified that it doesn't have to be compiled. JavaScript is a client side programming language that is run by the browser. This means that the individual visitors have a choice whether the JavaScript will run. Browsers generally support JavaScript more and more with each new release. A number of recently added enhancements are tied to JavaScript. In conjunction with JavaScript they already are a standard. Web pages are going from plain or hyper-text to application interface, which very often can be achieved only through JavaScript... |
| Why is JavaScript so dangerous? | |
 |
Many people will say,
JavaScript and computers in general are dangerous, going out of control, as DARPA... Rupture Preachers oppose
Doomsday Gurus! We are sick and tired of all the whiners who fool themselves that they are
more important then they actually are, seeking some mystical powers or security...
agonizing or fret over the life. Yes, JavaScript is dangerous but alcohol, cigarettes,
guns, drugs, cars, industry, politicians, patriotism... everything is dangerous! (wow,
that's specially dangerous when everything is dangerous!)... Microsoft is evil. FireFox
and Opera are good. They are fast, secure and have PNG support... There was an
interesting point from Collin Yeadon about FireFox (http://ygteam.blogspot.com): All browser are just browsers. They cannot be GOOD or BAD, just more or less USEFUL, so we should use it and shut up! Woo-Hoo! That's the talk: "which browser do you like the most - shut up! We don't care!!!" |
| How "PNG Image" appears in your browser? | |||||
 PNG Image |
PNG-Alpha Support (24bit Alpha Transparency Test) If test image on the left is circle-shaped your browser supports alpha transparency, otherwise you need to upgrade your browser. Alpha transparency is used very often now. If page has a transparent image, without this support, transparent image may cover an important information. |

| Sanela Home Page Access Tips | |
 |
This site is divided
in two major sections: 1). ALL-Section -- should be accessible to "all" browsers 2). JAVA-Section, accessible only to Web2 compliant browser This site is running only on JavaScript and few rudimentary FrontPage extensions. No ASP, no PHP, no JSP, no ColdFusion... nothing else. If we turn off JavaScript, we turn off the whole site. Many new technologies in Web2.0 core rely on JavaScript: API, DOM, CSS, DHTML, XMLHTTP... You just make sure you have an up-to-date browser. Most of our pages are directly fetched from server so you need to have a newer browser capable of XMLHTTP technology. Most of inter-page linking is done with JavaScript so you need browser with good JavaScript support. Some of resources are controlled over session-cookies so you need to have cookie support enabled, at least session-cookies support. Most of these characteristics are highly dependable on server speed. All callbacks are limited to 20-seconds timeout and it is very likely that page-load will timeout often. If so, you will receive a message about it; try to refresh your browser; wait few moments and try again... if error persist, please, fill up the Bug-Report-Form and help us learn about it. |
