The Quickest Way to Becoming a Pro Developer

Come yung’uns, gather by the fire that I may tell you a story… well more of a walk-through really… The older kids have heard it before and have gone on their separate ways… Now, you’ll hear it and make your choices and go your separate way… I see you’re all fresh-faced and want to make a splash at being a developer but you feel inexperienced and unequal to some of the bigger boys and girls out there. You wonder, ‘what can I do to become a pro ASAP?’ Well huddle ’round the fire quickly and listen, before you start asking yourself why are a bunch of ‘young’ developers huddling around a fire to listen to an old man? Wait, what’s happening, where are we?!

1- Learn Your Foundations Well: Foundations being the languages; HTML5, CSS, JAVAscript, etc. Understand the client-server model, understanding the relationship between client computer, server computers, client apps, server apps, etc… <SHAMELESS PLUG1: Check out our links at the bottom to a bunch of awesome and beefy courses which will detail everything you will nedd to know>.
2- Frequency of Exposure: Simply put: the more you code, the better you get at it. You can read a book or watch a video but if you can’t put the theory into practice, how much have you retained? How much can you really use?
<SHAMELESS PLUG2: Our courses have a wealth of questions, quizzes and exercises to make sure that you can put what you just learned into practice.>
3-Start Building Little Mini-Projects: You don’t have to build a “facebook” right outta the gate. Tiny, diverse projects will get you way more all around experience. Then you can start building small projects that actually do things for yourself or others. Ex: build a shopping cart that integrates with paypal, build a basic login system, etc…
4- You’re Always Learning New Things: Obviously, a developer of 10 years has a lot less to learn than a dev of 2 years that they’re STILL learning. It keeps you sharp and versatile. Which brings us back to point #1, if you’re well versed in your foundations, learning new stuff is pretty easy…

Well, that’s it yung’uns…
Any questions or something you need more explanation on, check out this Vlog where we go into detail on all the points and of course, feel free to check out the links below to our courses, you won’t regret it <SHAMELESS PLUG3>. I’m going to go talk to our location director…

The Jabba About Java

March 27, 2019

Hard to learn, easy to write … but slow to code with

Full disclosure: I love Java and in some ways, it can be easier to write than faster-to-write languages like JavaScript, Python and PHP. That being said, I wouldn’t use JAVA today in most situations… I know, I know, I can hear the rage-typing right now as the JAVA cavalry sweeps down the hill, charging towards me, but hear me out…

It’s hard to learn, even compared to other languages (like PYTHON, JAVAscript or PHP). It’s hard because “…you have to declare everything. …You have to explicitly write out everything your code is doing. …There’s a lot less things done automatically for you.” Which can be good: as a programmer that means there’s a lot less errors creeping in because there’s not really any “implied coding” (explanation in the video), BUT the coding you do write is super-detailed and verbose.
ALSO: It’s dog-slow at run time when writing desktop applications (never mind mobile apps).

-Totally dating myself here- JAVA was a great language for it’s time in the 90’s. “Because when you wrote JAVA it just worked…and it was very consistent. …JAVAscript: relative to JAVA was very inconsistent …it had some really weird, wonky behaviors and it could cause some really stupid little bugs that could cause you to pull your hair out trying to chase them down in JAVAscript, whereas you didn’t have that occur with JAVA.” I’m also not saying that JAVAscript is bad, in fact most companies toady are leaning towards lighter, faster languages and JAVAscript fits that build (especially when compared to JAVA).

So there you have it, from a guy that loves JAVA. It’s super verbose and heavily detailed in the writing (which also means less errors because you’re being explicit), and that writing code takes much more time, much more time means much more work and money/cost: “I wouldn’t do it.”

Check out the video for a more in-depth explanation PLUS what’s coming up with us with STUDIOWEB and other fundamental stuff we’re working on; super exciting stuff!

Now You’re Speaking My Language

March 14, 2019

What Programming Languages do the Most Popular Websites Use? The results may surprise you!

So, I was on what the kids call wiki-wiki-pedia the other day and I thought I’d look up what programming languages the most popular websites use. I know, most people look for civil war factoids or if their favorite band from their teenage years is still around but I guess I’m just weird like that…

Now, I’ll be honest with you, it’s better to watch this vid to see firsthand what I’m talking about but, quick spoiler, on the front end (that’s to say “code that lives in the web browser”.) it’s all JavaScript. But what’s most surprising is the back end where it’s almost all JAVA, PYTHON, C, C++, PHP, etc. Yup, pretty surprising (or not, if you’re pretending to be one of those “I’ve seen it all” programmers). The reason I bring this to your attention is that I want to “give you some insight into how effective a programming language is; how ‘serious’ a programming language is…Some people look at a programming language and say ‘it’s not serious, it can’t work on big projects’.” Well when you consider what these giants of the industry are doing (and you’re assuming they know their onions), you start to see that these languages are still very capable of doing the “heavy lifting”.

But seriously, check out the vid to put it all into context.
Also, blink and you might miss it: another quick dig at RUBY (mwahaha). Enjoy!

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

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.

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; } } } } }

Matching Columns Script – Update.

February 17, 2007


I decided to create another blog post to make it easier to find the updated version of the important matching columns script – it was buried in the originals article’s comments.


Updated script by: Jonathan del Mar

I have modified the script to work with multiple class groups also with elements with multiple class names

Derived from a script by Alejandro Gervasio.
Modified to work in FireFox by Stefan Mischook for

Modified to work with multiple class groups also with elements with multiple class names
by Jonathan del Mar (dec-14-2006)

How it works: just apply the CSS class of ‘column’ to your pages’ main columns.

to work with different classes

var columns = new Array(’class_name1′, ‘class_name1′…);

by Jonathan del Mar

by default the script will call
and the default class_name is ‘column’
(see the bottom of this script)
by Jonathan del Mar


var divs,contDivs,maxHeight,divHeight,d;

// get all elements in the document



// initialize maximum height value
if (!my_class) {
my_class = ‘column’;

my_regex = new RegExp(’(.* |^)’ + my_class + ‘( .*|$)’);

// iterate over all elements in the document

for(var i=0;i elements with class attribute ‘container’

// modified by Jonathan del Mar to match ‘column’ in multiple classes



// determine height for element




else if({;


// calculate maximum height




// assign maximum height value to all of container elements

for(var i=0;i
var columns = new Array(’class_name1′, ‘class_name2′, …);

to your html header.
