RSS Feed Twitt Bots

The open source world has always be a great source of energy to all especially for code monkeys and terminal junkies, not all sharing code, but also happiness to the whole world, indeed with the free as in freedom making life more better.

I coded the below two piece of code, one in python and other in ruby to update twitter stats which would be the title and shorten link of the RSS</acronym feed provided.

In the code below, the RSS feed URL considered is of the h3manth.com and is.gd api is used to shorten the url, the other dependences are listed in the comment section of the code.

        if chk_feed.status == 200:
