WebTTY is an interesting package. During my internship I actually had to do something like this. My employer didn’t appreciate a pre-packaged solution though, so I had to produce all the code myself.

The WebTTY package allows any Linux terminal processes to be controlled in a text area HTML element on a webpage. The output from the server process is collected on server side, and is send to a text area element. Keypresses in textarea are collected on client side and send to the server process. WebTTY uses AJAX/DHTML patterns to achieve in-page updates without refreshing the entire page.

Bill Scoot over at Looks Good Works Well wrote a very interesting article: Nine Tips for Designing Rich Internet Applications.

Here’s a synopsis:

1. Make it directly interactive
2. Make it inviting
3. Use lightweight, in-context popups instead of page transitions where possible
4. Use real-estate creatively
5. Cross page boundaries reluctantly
6. Create a light footprint
7. Think of your interactions as storyboards
8. Communicate transitions
9. Think in objects

Most of this we’ve heard before, but I like lists

I found this rather interesting:

One of the more interesting aspects of Ajax is the ability to track a user’s interaction within the browser. I wanted to investigate navigation patterns, so I have written an Ajax based link tracker. If you press the “Ctrl??? and "X" keys you will be presented with an overlay which displays links usage by percentage. This functionality was created with JavaScript and a very simple API.

Very inventive use of Ajax.

Honestly I don't see why this hasn't made more of an impact because this script is awesome. One of the pains that Ajax developers go through is debugging. Now, with the help of Greasemonkey the XMLHttpRequest object can be traced.

The Greasemonkey script was written by a guy named Julien from Curiosity is bliss. Trust me, XmlHttpRequestDebugging is one script that is going to save a lot of time with Ajax development.

Please make sure you get the updated version though.

After reading posts from Dare Obasanjo aka Carnage4Life and Links on the Semantic Web I noticed that some people are having problems when making AJAX calls from one serer to another.

I believe is the problem that most would come across:
Error: uncaught exception: Permission denied to call method XMLHttpRequest.open in Mozilla Firefox.

And here is the fix: Just insert this block of code right before you declare the new XMLHttpRequest object:


try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
} catch (e)
{
alert("Permission UniversalBrowserRead denied.");
}


I sure hope this helps some people.

What Is Ajax?
— It's become very popular lately, even though it's not exactly new. It's been possible to use the concept behind AJAX since browsers introduced the XMLHttpRequest function in 1999. Enjoy Rob Gonda's highly popular ColdFusion Developer's Journal article on AJAX, the hottest software development of 2005, with plenty more heat promised for 2006.

I know there are many out there, but this one comes from the guys over at Ajax.sys-con.com, which is the new Ajax Website that has just been unveiled.

We've seen and heard a lot about Ajax in 2005. Here is the Ajax year of 2005 in review:

The AJAX Year In Review
— The term (and world-wide attention) behind AJAX is not even a year old, but you can find a wide range of powerful tools either with newly added support for it or created just to support the AJAX way of life. In addition, many of the constaints and problems with AJAX have been resolved or greatly reduced. But keeping track of all these developments is very difficult, so Dion Hinchcliffe has compiled a summary here of the major advances in AJAX so far this year....

One of the things that stood out for me in this article was the section on:

Improved Ajax Techniques

• Content with Style: Fixing the Back Button and Enabling Bookmarking for AJAX Apps
• Saving Session Across Page Loads Without Cookies, On The Client Side
• Call SOAP Web services with AJAX
• Ajax using only an image
