Prune Run Configuration Meta-data in Eclipse

Sometimes Eclipse IDE fails to clear or prune stale meta-data. One such instance that you'd come across is the stale run configuration for an (Android) application.

Batch convert media files using ffmpeg and ruby



So you have those old videos taken in your handy-cam that you'd want to convert to mp4 for better compatibility across devices and less storage footprint? And you want to batch convert all these videos?

Automate title metadata tag to its file name

Don't see media titles in your playlist of your media player. Chances are the title meta-data isn't set for those files. This blog post is a recipe to fix this situation, assuming you're a developer :)

What is Object-Oriented Programming?


I haven't seen a better explanation about OOP till date than the one given by a guy who never had any formal engineering training but always had clear idea about everything he did and preached, be it technology,design or art.

Here, in an excerpt from a 1994 Rolling Stone interview, Jobs explains what object-oriented programming is.

Supervise your node app in development


It's such a pain during the development of node.js apps that we often forget to restart our app after the changes are made in the source code of the app. And even if we are diligent enough to remember and restart the node server after every change, it is still a pain.

Express 3.x - Web-app framework without Web-server

This image is not the logo of ExpressJS
Looks like with Express 3.x the code is more modularised. Express framework is now a web framework devoid of web server functionality.

For the sake for simplicity and clarity by comparison, check the code pre and post Express 3.x version, all by yourself. I believe the code is self-explanatory.

And I should say, I like Express 3.x this way - loose coupling.

Convenience of Ruby's Readline

What API do you use to get input from terminal for a CLI app - use the combination of gets and chomp in ruby? That is okay. But didn't feel some pain trying to input again (and again?) in case of any input typo/error? Didn't you wish the CLI-app in ruby mimic the completion feature or the history feature as in the terminal?

Debugging Shebang

Coding is eternal fun and learning exercise. Take the case of an example code snippet below that I tried to run like $ ./debugging_shebang.rb in the command line and it threw an error like -bash: puts: command not found

When to freeze, clone or dup in Ruby?

I try out expressing my intent in different forms to see what works effective. This time around, I'd like to story tell the code as if it's evolving over a pair-programming session. I'd appreciate your constructive feedback.

Warning the examples in story you're about to read might be super contrived and redundant. I'm merely trying the story-telling way to explain concepts with examples in the hope that you get near first-hand experience of pair-coding and experience learning. Chew on the concept leaving the contrived examples and story behind :P

Exploiting tap in Ruby

The instance method tap is available as part of Object class from Ruby 1.9.x onwards. Rubyists exploit it to different use cases for fun and fashion. This blog post is to share my thoughts on what I think tap is best for.

Require versus Load in Ruby

The big difference

  • While you load a file, you require a feature
  • Every time you load, you load a file into memory. On the other hand, every time you require you is if it has already been required to avoid repetition
  • require is more abstract an API than load. So typically for you're day to day use, you'd require not load.
  • Because you load a file, the load method takes the input argument having file extension. The file extension is excluded in the case of require method.

Lessons from Mark Zuckerberg at Startup School 2013

Mark Zuckerberg gave a very candid and open interview at Startup School 2013. I liked it so much that I wanted to scribble some points from the talk. And this blog post is a bulleted list of lessons I learned from Mark.

Steps in contributing to an open-source project in Github

Often times we find it compelling to contribute to someone else's project, either because you added a new feature to it or fixed an existing bug. This way you feel proud that you're giving back to the community project that helped you from re-inventing the wheel.

Git/Github has simplified and made intuitive the entire process of code contributions to other's repositories.

"this" operator in JavaScript


This blog post is my notes on "this" in Javascript, which is largely and shamelessly reproduced from Daniel Trebbien's answer in StackOverflow. (Thank you Daniel, you made my day!)

The ECMAScript Standard defines this as a keyword that "evaluates to the value of the ThisBinding of the current execution context".

And, ThisBinding is something that the JavaScript interpreter maintains as it evaluates JavaScript code, like a special CPU register which holds a reference to an object. The interpreter updates the ThisBinding whenever establishing an execution context in one of following cases:

Understanding call and apply in Javascript by example

In Javascript, call(..) and apply(..) does the same thing, just that the way each takes input feed is different. All Javascript Function objects have these methods at their disposal.

The CSS Box Model

If you've been struggling with positioning and alignment of contents in a predictable manner, especially in a web page that you working on is responsive, the first check is to figure out if you understand how the full element dimensions are computed. Well, there are other things to check as well, but this blog post is focussed on that basic thing that you should have know - the CSS2 thingy.

Positioning with CSS

The positioning of UI elements has always been a little tricky thing. If this is you, then this blog post is for you to get out of this situation (hopefully!).

This blog post explains through examples the implications of using different CSS values for the CSS property - position.

Note that this property applies to all elements. And margin is applied after the position offsets.

Also note that elements usually can be positioned using the top | bottom | left | right properties, that work differently depending on the positioning method mentioned below. And these properties will not work unless the position property is set first.

Love is blind and so is anger

For the curious this is a poem that I had written, perhaps a decade ago for some college competition. Luckily, I stumbled on that very paper on which I wrote this poem. Just make sure I don't loose my work, I'm now filing it in my blog.

Like a western story telling style, I leave the plot of the poem to the good imagination of the readers.

This blog post is a note to self so that I can read and re-read it to help me get on track.

Conference: Dev Day 2013, Colombo, Sri Lanka

I had the good opportunity to deliver a talk in Dev Day 2013, Colombo, Sri Lanka. What was more interesting is the fact that there were many opportunities in the form of surprises resulting in a lot of learning. So I played the roles of an audience member, a speaker, guest interviewee, and finally an interviewer. I can't ask for more, can I??

Conference: JSConf 2013, US - Javascript Masterclass by Angelina Fabbro

I stumbled on this talk by Angelina Fabbro on Javascript Master class in JSConf US, 2013 which to me is very enlightening. Her talk is about becoming an expert as an intermediate (Javascript) developer.

Angelina Fabbro is a programmer based in Vancouver, Canada and works at Steamclock Software. Angelina has a background in cognitive science, building clever robots and researching what people pay attention to. Her record as a web developer is balanced with modern iOS experience and a keen sense of design. Angelina also both teaches and mentors for the Vancouver chapter of Ladies Learning Code.

Schooling and Learning

Our (Indian) educational system is terribly pathetic. It pains. It hurts. Because the foundation is so bad, there is no wonder that we see a ton of problems unsolved to say the least.

Parents send their kids to school not with the goal of enhancing the kids knowledge through education and learning. They do so because they want their kids to participate in the race of discrimination very early on in life, hoping it would prepare them to land in cosy jobs. Tell them that what they do is wrong, they instantly hit back citing the corporate advertisements or job boards. Heck, it's a vicious circle that nobody wants to break.
