Raahukaalam, Gulikai and Yamakandam are well known timing schedules in Hindu religion. They denote the good and bad time and vary for every day of a week and are constant for all weeks of year. To fetch this timing either per day or as a week, one can make use of this gem in their application to fetch the required details.

The gem code is available online here and the usage steps can be known from the gem's home page.

The Periodic Table is a pure HTML based project to know about the different elements in the famous Periodic Table. It displays all the elements with their details such as atomic number and atomic weight. I worked on the coding part, while my team mate Mr. V. Manoj Kumar helped me in collecting the required details. The project can be viewed as working website here.

Chess is a 2 player game designed by me using C++ programming language. The controls are only through keyboard. The coin is chosen by entering the position of the coin and the final position for the coin is chosen as the same. The program validates if the move is a valid or invalid move by using a miniature version of chess board.

The miniature version of the chess board is a 8x8 array where black coins are represented using lower case alphabets a-h and white coins using upper case. This minitaure version along with other important variables' values can be stored into a file, there by saving a game's progress and continuing to play it later.

EUSIL is a programming language developed as a tool using C++ language. This application was developed as a result of an idea that came up during a class in System Software subject (in UG) to parse variables in a program. During the stages of development, it was thought to be a programming language. Later realized that it is not a programming language and what I had developed is just a tool.

EUSIL had the first version v1.0 released via my blogspot. Later it was brought down due to some reasons.

This project was developed twice. Once during my school days and later during college.

During school days, I did not have the knowledge to get system time using C/C++ program. So I took MS Office's Power Point and used Rehearse Timings option to achieve it. The issue with this approach was that, a consistent power back up was required to keep the slide show running all throught the day. If power goes off even for a second, then the slide show will get cut and everything will go out of sync. Hence it was rejected.

During the end of my college second year (2009 mid), I developed the same application using Applet. Applet program fetched time from the system and played a bell sound when the exact time arrived. Also the prayer song and other songs such as National Anthem were programmed to be played at correct timings. Separate programs were written for bell ringing during semester examinations.

* Currently the applet programs are not running on browser as the support has been terminated. The actual intention of this project was to embed the applet in HTML pages and use them.
