Over the past twelve months, 154 developers contributed new code to FD.io. This is one of the largest open-source teams in the world, and is in the top 2% of all project teams on Open Hub.
For this measurement, Open Hub considers only recent changes to the code. Over the entire history of the project, 302 developers have contributed.
The first lines of source code were added to FD.io in 2015. If this older project has had recent activity, then this project likely is consistently delivering value, and attracts sustained effort from the community.
A longer source control history in conjunction with recent activity such as with this project, may indicate that this code base and community have enough value to hold contributors' interest for a long time. It may also indicate a mature and relatively bug-free code base, and can be a sign of an organized, dedicated development team.
Note: The source code for FD.io 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.
FD.io is written mostly in C.
Across all C projects on Open Hub, 19% of all source code lines are comments.
This holds true for FD.io as well. It contains the same ratio of comment lines to code lines as the majority of C projects in Open Hub.
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.
Over the last twelve months, FD.io has seen a substantial decrease in development activity. This could mean many things. It may be a warning sign that interest in this project is waning, or it may indicate a maturing code base that requires fewer fixes and changes. It is also possible that development on this project has moved to a new source control repository somewhere else.
Open Hub makes this determination by comparing the total number of commits made by all developers during the most recent twelve months with the same figure for the prior twelve months. The number of developers and total lines of code are not considered.
