It was an awesome experience to deliver Seminar on Android on the occasion of Software Freedom Day which is celebrated on 3rd Saturday of September every year. Software Freedom Day started in 2004.
I was invited as guest speaker to talk about Open Source Software Android on 21st Sep. 2013 at Ballarpur Institute of Technology (BIT), Ballarpur, Dist. Chandrapur, Maharashtra (India). They had even organized nice competitions too on the occasion of Software Freedom Day.
