Ajax – Javascript

Java for Apps in 2019

May 21, 2019

First things first, a kick-ass opening for this vlog with a (literally, for those afraid of heights) breath-taking view of Montreal, and then back into the “studio” to check out my rig (drums), all to a slick tune in the background. Maybe we’ll call this segment, “Weeee, so fly.”

But let’s dive right into it… Should you use JAVA for back end web app development?

A very specific question deserves a very specific answer: “At the end of the day you have to always judge your technology stacks based on both technical implications of the choice and market implications.”

Technology implications: Do you have experience with the language you’re using? Are you comfortable as programmer? “It depends how nerdy you are, if you are very comfortable writing code, you’re very comfortable as a developer and you’ve done web apps before, yeah, JAVA, could be a good choice, but you gotta consider more than just the technical aspects of the language…”

In terms of market implications: “…are there jobs there? Is there a long road ahead for that particular technology stack?”
Now, there are plenty of jobs in JAVA but they tend to be in or with larger businesses/ organizations. Even with smaller businesses or freelance work “JAVA would not be my first, second, or third choice…”.

Check out the video for a super detailed answer to this question and the more broad lesson that we’re trying to teach: What can you do Vs. what will the market pay you for. Also, did you find our RUBY diss(es)? Oh, yeah, there might be more than one!

Flash CS6 goes HTML5

April 27, 2012


As predicted, Flash has now gone HTML5 – yes, you can now export your Flash work to HTML5 using the new Flash CS6.

I haven’t had a chance to look at it, so I have no comment with regards to how well it works. Nonetheless, this is more evidence that HTML5 is going to be huge in the future of web design and web development – if it isn’t already!

Flash CS6 basically uses the CreateJS open source framework, to output animations in Flash. I don’t know how powerful this conversion process is yet … we will soon see how complex the Flash projects can be and still be able to output them via HTML5.

Whatever the case, you should still be learning HTML5 and JavaScript.

I created a video blog on this:

Beginners Javascript Video Tutorial

October 10, 2009



Today, the Web is a much more sophisticated place (dynamic shopping carts, blogs, DOM scripting, Ajax etc) … a Web that requires much more sophisticated web designers. To be a competitive and modern web designer these days, you have to learn more than just HTML and CSS .

The ‘foundation’ languages of web design today are:

2. CSS
3. Javascript
4. PHP

You don’t have to become a full-fledged nerd coder but you should at least understand the basic concepts and be able to read and write basic scripts. This way, when a client or your boss comes to you with some shopping cart script that he wants you to install … you wont be freaking out because you don’t understand a thing.

So in keeping with my goal of training you guys and girls up, I just wanted to announce my latest video tutorial; a course on Javascript: Beginners Javascript.

Introduction to the Javascript DOM

September 20, 2009


The DOM is short for: Document Object Model. This is basically a virtual map of the currently loaded web page. You can use this map along with the help of Javascript, to travel about your web page and do things like:

  • Insert tags
  • Remove tags
  • Insert text

… And a whole lot more.

The DOM is the key to all those cool Javascript and Ajax affects that we now see all over the Web. Check out my new video that introduces you to the DOM and I also teach you an exercise I came up with to help you better understand the DOM:

You can find the entire Javascript beginners course at

Thanks for watching.

In this video I introduce you to two things:

The goal of this video is to give you a birds eye view of Javascript, to hopefully make it easier to understand how to use this language in later videos.

This video is from my very soon to be released Javascript basics video tutorial course.

Automatic Table Styling with Javascript.

January 10, 2008

A while back a wrote a JavaScript script that automatically styled an HTML table. In a nutshell, the script automatically changes the background color of every 2nd row in an HTML table.

Anyway, someone recently sent me an updated version of the script. You will probably want to read the original article before looking at these changes.

From the email:

I did some simplification on the code for zebrastripes. I don’t bother with the last array bit because TR elements have the bgColor attribute.

trs[i].bgColor = ( i & 1 ) ? stripe_colour_even : stripe_colour_odd;



The complete function:

function stripe_table(id_name) {

var my_table = document.getElementById(id_name);

/* For debugging */
if ( !my_table ) {
alert(“The ID ” + id_name + ” is not found.”);

/* Table may have more than one tbody element */
var tbodies = my_table.getElementsByTagName(“tbody”);

for (var cnt = 0; cnt < tbodies.length; cnt++) { var trs = tbodies[ cnt ].getElementsByTagName("tr"); /* Walk table row for row */ for (var i = 0; i < trs.length; i++) { if (! hasClass(trs[i]) && ! trs[i].style.backgroundColor) { trs[i].bgColor = ( i & 1 ) ? stripe_colour_even : stripe_colour_odd; } } } } }
