ng-if VS ng-show

So my angular app was taking longer than i expected it to load yesterday. It was a tiny app, not more than say 50 lines. Turns out i was running into an issue with ng-if.

ng-if does something depending on the true or false evaluation of its expression.

Turns out ng-if removes or recreates an element from the DOM, and recreates the DOM tree from scratch.
Every removal destroys the old scope and every recreation creates a new one. Not good if ng-model and ng-if together are inheriting something from the parent scope. Not good at al!!

On the other hand ng-show and ng-hide simply modify the CSS(namely the display property) of the DOM element. The element is never destroyed.

Additional documentation : ng-If

Accessing Coursera learning material offline

Image
So Coursera is awesome right? But one thing that really bothered me was that I was not able to access material offline. My commute is a whopping 3 hours so yeah, I could make use of that time to read up on stuff!! (Yes i do look out the window.....but still!) There is this repository on Github suggested by a co-worker that is excellent for this exact purpose. But getting up and running is a little difficult for someone who may be isn't into programming or may be new to Python as well. (Python is a language used to do a lot of stuff , but is popular for data analysis). Before you begin you will need a Coursera account and be enrolled (free or paid) in a course. So whatever be your background, do the following to get access to the learning material of your Coursera course offline. This will download the learning material to your computer in a very organized way and you will be able to read and watch videos without needing the internet. Oh also goes without saying

d3 Collapsible tree vertical

Image
I have just finished playing around with M. Bostoc's collapsible tree. Here is a link to his original version. This tree has a right to left orientation, and I wanted a top to bottom. He does provide an option for tree orientations here .  Sources showing how to vertically orient it online, showcase a very simple non interactive tree.  SO i just changed his original code a bit, just small x, y tweaks (mainly the diagonal and the node transitions). Quiet simple actually. And this is what it looks like.  Also including the code and the hierarchical JSON object used.  Hope this helps. :)

Fixing $env.TOMCAT_HOME directory creation in eclipse

Image
I ran into this issue when I cloned a Git repository, was running the ant build and was trying to deploy the build to Tomcat. And every time I did that I got a status of the WAR file being deployed to ${env.TOMCAT_HOME}/webapps. This created a new directory of the same name in the project....and I could not deploy the project....well because it WAS NOT deployed to Tomcat. ${env.TOMCAT_HOME} was being treated like a 'string' in the ant build...not a variable like it should be. And I had something looking like this. I tried looking into setting environment variables on my machine...tried another round hopelessly with root privileges ......to no avail. To make my temper worse I had done this once before successfully on a friend's computer....had very smartly bookmarked the blogpost that mentioned how to do it and now....that entire blog had been removed. On a Friday evening after a full day's work...yeah...right.....i know! Only when I was going to give u
