FLAPPY BIRD- PYGAME

Finally feels like i have completely utilized another vacation. We malayalis have a lot of special festivals and traditions, and the months of August-September are the most important among all.. because during this time its ONAM. No college for 10 days and its goddamn boring especially when your cousins are not around. And the only solution left out to drive away your boredom..... LAPTOP and CODING!! 

Well, the idea of Flappy-bird popped long back.. but i wasn't actually into coding it, because i thought, this is a game thats so famous and people die playing it.. then should be really hard to code. Well I am not that an expert. But at last i thought lets give it a try... and TaDa..... I am here with code. It took almost 3 days to complete this to be more specific 2 days and 4 hrs. 

Here is the github link, you can get all the files you need to successfully run the code there.

MY SECOND PYTHON GAME

Well, it was really a huge surprise for me that i made myself up for coding a new game in python. after a weeks work on a shooting game I had left it all thinking that, "this is not my kind of stuff!". But my passion for coding did never end, and out of nowhere, the spark came up, and i started up my work on the code again. It took just 24 hrs to complete my whole code for the game which i named  as BALL SHOOTER. Actually i wanted to shoot out falling aliens, but unfortunately i couldn't get suitable image files. I have also included sound effects in this game, thought it is a flop try.
Well, here is the link for my code in github. Any programmer may try.
Here are a few screenshots.

RUBY ON RAILS WORKSHOP

 We had a two day workshop on ‘RUBY ON RAILS’ organized under the FOSS cell of Government Engineering College Sreekrishnapuram  from 18^th January 2014 to 19^th January 2014.

The resource person, Mr. Sumit M Ashok, is an engineer currently serving BangTheTable as their Developer with Ruby on rails.

First Session started with an introduction to Git, a version control tool and later the class was mainly confined to the basic concepts of Ruby, object oriented concepts of the language, classes, objects and methods. The session was very interesting due to the simple and interactive mode of teaching.

Second session dealt with more complex concepts of the language like operators, iterators and the concept of Meta programming as well as the use and actions possible on arrays. The class came to an end with a detailed description on request response cycle (MVC).

Second day morning session covered fundamental ideas of ruby on rails, a review of concepts like model, view, controller and their interconnections. The class gave a very smooth introduction to RVM, GEMS and RAILS along with the concepts of web application development.

The afternoon session was a practical implementation of the previously learned concepts. The students were ably guided in working on ruby on rails console and further created a simple web page.

On the whole this workshop on ‘Ruby on Rails' with Mr. Sumit was really a whole new experience, and was really helpful in gaining some basic knowledge on Ruby as a language and web development using Ruby on rails. The programming concepts learned will be very useful in establishing a carrier as a programmer.
