Introduction

Enterprises today require agile platform for rapid development of applications with ready assurance to quality of services, compliance to architecture and design standards. Two key things influence our ability to be agile. First, it’s the attitude of everyone involved. Second it’s the languages, framework, and tools we use to get our work done.

Creating JAR files with dependencies

Phill's J2EE Blog

File this one under “spend a few minutes Googling without success!”

If you’re trying to package up a Java application into one JAR file for easy deployment – including all dependency JAR files – there aren’t many options.

There’s a plugin for Eclipse called “Fat Jar” which I haven’t tried out. I’ve just discovered a tool called One-Jar, which does the trick. It’s simple to use. In my case, using Ant, it was a matter of:

  • Download the One-Jar JAR file.
  • Run it (using java -jar) to extract the contents
  • Add the one jar ant task plugin .jar file to my ant lib folder
  • Import the one-jar-ant-task.xml build file into my build file
  • Create a manifest.mf file with the One-Jar-Main-Class set
  • Add in the <one-jar> task to my existing build.xml file as per the instructions.
  • And you’re done!

The ant task does a lot of the work…

Whispers of the Sunrise

Naziyah Mahmood

salah

Deepest slumbers, gently nudged, by the softest voices of my travelling conscience;
“Awaken, my sweet, come to prayer, come to salvation”
The words rolling through the skies, over the hills of atonement.

Fading moon, rising sun, light kisses on their mutual passage through time;
“Cleanse your soul, illuminate your being, I am waiting”
A gap in the dawn, veiled by the radiance of His Majesty and Grace.

Silent struggle, standing tall, ascending towards self purification;
“Spiritual cleansing, physical ablution, absolved from worldly bounds”
An incandescent aura, emanating from every limb and every motion.

Open soul, intimate words, a liberation through prostration;
“Free yourself, share your tears, I am here”
An elevated state, reached through the humbling gestures of adoration.

Rising up, heart content, facing the day with a reinforced hope;
“I am with you, I have always been with you, and always will be”
Sweet whispers of the sunrise that…

Why learn algorithms and data structures ?

Vishwanath Krishnamurthi's blog

The question is – Why learn algorithms and data-structures ? 

and here are some thoughts. Probably you’d find this question answered in the preface of any algorithms book but anyway, here’s my take.

1) To not be constrained by the programming language for data-structure

Without a good knowledge of various data structures, it is easy to be constrained to thinking for solutions in terms of the data structures directly provided by the language.

If you were a Java programmer, you’d probably be thinking on solutions just in terms of what is provided in java.lang.util package.

Well, there’s lots more. Take for instance a simple need:  In a low end, basic phone, as the user types something, you’d like to present the user with “auto complete” feature. Thinking in terms of the data structures readily provided by the language /libraries doesn’t help much.

A simple trie  would help here. For another example, to think of any…
