The first lines of source code were added to XMMS in 1999. Projects with recent activity, and a code base more than five years old are likely solving vital problems and delivering consistent value, and may be organized to reward sustained effort by an engaged team of contributors.
Such a lengthy source control history in conjunction with recent activity may indicate that this code base and community are important enough to attract long-term commitment, and may also indicate a mature and relatively bug-free code base.
Note: The source code for XMMS might actually be older than the source control history can reveal. Many new projects begin by incorporating a large amount of source code from existing, older projects. You might be able to tell whether this is the case by looking for a rapid rise in the amount of code early in the project's history.
XMMS is written mostly in C.
Across all C projects on Ohloh, 19% of all source code lines are comments. For XMMS, this figure is only 12%.
This lack of comments puts XMMS among the lowest one-third of all C projects on Ohloh.
A high number of comments might indicate that the code is well-documented and organized, and could be a sign of a helpful and disciplined development team.
The source code for XMMS has not been changed in over a year.
Over 75% of all projects on Ohloh have no recent activity. Open source has a "long tail" of projects whose developers have moved on. But the code is still there for all to benefit from!
For this measurement, Ohloh considers only recent changes to the code. Over the entire history of the project, 18 developers have contributed.
