Fixing $env.TOMCAT_HOME directory creation in eclipse

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 up I decided to look into the properties of Ant. Not the individual ant builder in my project but Ant properties in Eclipse.

To fix this issue I had to add a property to the Ant runtime for it to recognize the TOMCAT_HOME and therefore deploy it correctly. So do the following.....(seek and thou shall find!!)


  • Eclipse > Preferences > Ant > Runtime. 
  • Click the Properties tab and the 'Add Property...' button. 
  • Then add the TOMCAT_HOME property like this 



  • Click OK > Apply > OK. 
  • Now delete the unwanted ${env.TOMCAT_HOME} folder created, as can be seen in the picture above. 
  • And re run your ant build. This time Ant will treat ${env.TOMCAT_HOME} as a variable, not a string and deploy your build (my WAR) in this case to Tomcat. 
  • Confirm by looking in your Tomcat > webapps folder to find your build. 
TADA!!

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. :)
