For those that don't know, Mr. Linus Torvalds is the founding father of the operating system called Linux. He led the development of the Linux Kernel. He was born in 1969, so he is still relatively young. Linux is based on a system of updates called software forks. The artwork is a humorous combination of Linus Torvalds flipping off (or throwing a finger) with fork substituted for the F word.
