Not your mother’s AJAX

by Rafael F
The article I researched has to do with AJAX and its benefits in the web applications developing industry. This article was written several years ago when AJAX was first introduced but promised readers and developers that AJAX was the way to go when developing web application interfaces. I chose this article as it served the purpose of confirming what we are learning in class right now. When preparing a web application sometimes it seems as if using standard HTML would be a lot easier to statically get the results that we are looking for. I know that for the second milestone of our course this was the case for me. I soon realized the static code was not as efficient as other languages could be. The same goes for building the web app interface.  read more...

JavaScript Causes Security Concerns

by Jonathan F

Websites have become more interactive thanks to JavaScript, but many are concerned that this scripting language can cause so security issues. Web 2.0 has allowed Websites to create a better user experience, and JavaScript takes advantage of this. Malicious JavaScript and Web site security flaws can lead to a security attack. JavaScript is a scripting programming language that was created in 1995 and is best known for its use in Web sites. Although the name has Java in it, it is not the same as Sun Microsystems’ Java .Now with Web 2.0 Web sites have become more interactive and a programming technique called AJAX has introduced more JavaScript in Web sites. David Wagner a computer science professor at the University of California Berkeley, said that JavaScript creates a major disaster because of its can be used in malicious ways. There have been a number of worms that have been created using JavaScript. A malicious script could be embedded in a Web pages and run on their own without the user even knowing. Malicious script could even be placed in Web sites through a flaw know as cross-site scripting. The best way to avoid malicious JavaScript is to disable JavaScript on your browser; the only problem with this is that a lot of Web- Sites won’t run correctly with JavaScript disabled. It is the responsibility of Web site operators to validate the JavaScript they use and try to avoid cross-site scripting. Malicious JavaScript has been around for a while but it has not been a major security until recently because of Web 2.0 and AJAX have made JavaScript a popular language to create interactive Web pages. read more...

AJAX Not So Bad

by Joeydes M
Summary:

This article is about the waves that AJAX is making at the enterprise level of development. AJAX is a client side object oriented toolkit that Microsoft provides to its developers. In Visual Studio it has drag and droppable components that allow for very sophisticated and modern website design. AJAX stnads for Asynchronus Javascript and XML. The article states that some Canaidian firms are finding a place for AJAX in their development practices. The article discussed some of the drawbacks to AJAX and some one of those drawbacks was the spin off s of the product, Microsoft has their version of it, as does Adobe (in the Spry package) it states that there are 100-200 different variations. This causes a lot of interoperatbility with web browsers. Google is trying to resolve this particular issue by releasing its own web developer toolkit and it combines these different types of design into one universal Java development platform. Another porblem that came up was the fact that there was not a lot of back end tools with AJAX and that means a developer would have to used two different langauges to program for both, it states ideally you would like to develop the back and the front end in the same language. read more...

Dr. Techo Junky

by Omar N.

The article titled “Healthcare 2.0” discusses how Web 2.0 has been integrated into our healthcare system. One example is where medical videos are shared by physicians on websites like askdrwiki.com. Blogs are also used by healthcare professionals in education by sharing some real life cases. This sounds like it would be breaking some privacy act, but the article mentions that it is allowed as long as names and medical record numbers of the patients are never revealed. RSS feeds are another thing that is mentioned has increased healthcare productivity. It alerts busy doctors when a new article is published to keep them updated on research in their field. On the development side, AJAX has also been used in training and educating by reducing access times for x-rays and other images that require immediate responses. The article also uses the term “bashups” as a way to describe the combination of business intelligence and mashups in the healthcare field. For instance, insurance companies can track claims. Google maps, among other application sources, has been a useful tool in tracking the patterns in the spread of diseases. read more...
