 Linux is growing -- that we knew. Now we know how fast.
 
 In the last two years, the number of developers who collectively create Linux has increased from 1,131 with version 3.0 in July 2011 to 1,392 with version 3.10, released in June 2013, according to the Linux Foundation's latest [annual Linux development report][1].
