Very High Activity

Project Summary : Factoids

Analyzed 5 days ago. based on code collected 6 days ago.

Mature, well-established codebase

The first lines of source code were added to NixOS in 2003. 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 NixOS 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.

Very large, active development team

Over the past twelve months, 1013 developers contributed new code to NixOS. 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, 1807 developers have contributed.

Well-commented source code

NixOS is written mostly in Nix.

Across all Nix projects on Open Hub, 2.6% of all source code lines are comments.

For NixOS, this figure is only 4.0%.

This high number of comments puts NixOS among the highest one-third of all Nix projects on 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.

Stable Y-O-Y development activity

Over the last twelve months, NixOS has not seen any change in activity. This may be a good sign, and an indication that development is continuing at the same pace and not dropping off.

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.
