Estimating fight between Manager and Lead
This is how they will treat the estimates
Take your time and do them well
Parametric equations
Varying a single parameter t , you are able to generate circle

Assignment on Parametric Estimates
Estimate the Web 2.0 project : What Tweet means
Explanation : The most notable persons on earth viz, Obama, Modi, Aamir Khan or Deepika Padukone are tweeting everyday. Often there is a difference between what they tweet and what they mean. Example See a Narendra Modi tweet and possible WhatTweetMeans

any tweet in text/image/gif and post it • Other people should be able to vote the interpretation up and down• The WhatTweetMeans – should be viewable by # of vote ups or time
currency of the posting.• People should be able to share the thread of what he means • They should be able to report abusive WhatItmeans.
