It contains an updated calculations of Software Lines of Code present in a typical Linux distribution. In the paper, the authors uses Fedora 9 as the basis. Guess what? It's estimated that it would require approximately $10.8 billion to build Fedora 9. Additionally, it would take $1.4 billion to develop the Linux kernel alone.
The assumption used on this article for US programmer salary was $75,662.0810 (according to US BLS - Bureau of Labor Statistics). Given the assumption, here's the results:
| Total Physical Source Lines of Code (SLOC) | 204,500,946 |
| Development Effort Estimate, Person-Years (Person-Months) (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05)) | 59389.53 (712674.36) |
| Schedule Estimate, Years (Months) (Basic COCOMO model, Months = 2.5 * (person-months**0.38)) | 24.64 (295.68) |
| Total Estimated Cost to Develop (average salary = $75,662.08/year, overhead = 2.40). | $10,784,484,309 |
And here's the results for the kernel estimation
| Total Physical Source Lines of Code (SLOC) | 6,772,902 |
| Development Effort Estimate, Person-Years (Person-Months) (effort model Person-Months = 4.64607 * (KSLOC**1.12)) | 7557.4 (90688.77) |
| Schedule Estimate, Years (Months) (Basic COCOMO model, Months = 2.5 * (person-months**0.38)) | 15.95 (191.34) |
| Estimated Average Number of Developers (Effort/Schedule) | 473.96 |
| Total Estimated Cost to Develop (average salary = $75,662.08/year, overhead = 2.40). | $1,372,340,206 |
In simple word, Linux has grown up and getting matured. It's getting bigger and bigger and compared to six years ago, a lot of new functionality has been added to Linux distribution.
