Biggest Paradigm Change in Enterprise Software:

Linux kernel

Created by: Linus Torvalds, in 1991, helping open-source developers collectively craft a viable alternative to Microsoft operating systems.

The Linux kernel contains 8.2 million lines of code, with approximately 86 lines added every hour

Number of developers: Total since 1991 is unknown; 3,200 developers for the kernel as of release 2.6.22.

New releases: Every 2.6 months.*

Quick change artists: 2.89 changes made to the kernel every hour.

Lines of code: 8.2 million and growing (about 10 percent per year).

Amount of code added every hour: 85.63 lines.

Revenue diverted from Microsoft: Perhaps only Mr. Gates knows.

*Unless otherwise marked, statistics reflect Linux kernel releases of the past 2.5 years (version 2.6.11 through 2.6.21).
