linux-logo.jpgWe have been using Linux for more then 18 years, without paying a single penny, Thanks to Open Source. There are more than 137000 registered machines, which are using Linux as their Operating System. Linux is the work of thousand of developers working as a Community. But have you ever wondered, what would be the development cost of Linux. Open Source does'nt mean that its Development Cost is zero. Two researchers have estimated the cost of replicating Linux kernel from the scratch at about 1.4 billion USD! Who said Open Source is free?

Jesus Garcia and Isabel Alonso from the University of Oviedo have estimated the development cost that would take approximately 1000 top notch developers around 14 years to replicate the giant Linux kernel. The cost estimation was done using Constructive Cost Model(COCOMO) 81 algorithm and the whole experiment revealed only the estimates and it was not intended for actual use.

But the point is that the sheer amount of development costs, the time span and the developers needed is mind boggling. Does this ever cross your mind when you use Linux?
