Bluefin is a high-performance predator. The team believes in instrumentation and telemetry as a means to improve software — but that information must be privacy-respecting via an open process so we can verify what is being shared.

Data, for me, is the foundation of F1. There's no human judgment involved. You've got to get your foundation right in data.

Countme Statistics​

Bluefin's CountMe Stats

The Fedora countme service is on by default in Fedora, and Bluefin inherits that behavior:

How the numbers are counted​

The chart above and the Factory metrics view are both derived from Fedora's published totals.csv using the rules in ublue-os/countme, which is the project's canonical implementation. Two of those rules matter for reading the numbers:

  • A hit is not a device. DNF sends a countme request once a week for each repository that has it enabled, so a machine with the base, updates, openh264 and source repos produces four hits. Counting devices means restricting to the single base fedora-N repo that each system has exactly one of.
  • Not every row is the same measurement. Rows carrying sys_age = -1 are a separate legacy unique-IP estimate that Fedora computes in a second pass and writes into the same file. They are excluded.

Two weeks are skipped outright: the partial week at the end of 2024, and the week of the July 2025 Fedora infrastructure migration, which shows a ~40% drop that reflects the migration rather than a loss of users.

Countme is an estimate, not a census. It only sees systems that actually ran dnf during the week, it can be turned off, and systems behind a mirror that does not forward the request are invisible.

Bluefin LTS is not comparable to the others. It is CentOS Stream based, so it has no fedora-N repo and reaches Fedora's counter only through EPEL. Fedora's own infrastructure treats EPEL countme figures as an undercount. Read the LTS line as a floor, not as a share of the same population.

Homebrew​

Homebrew analytics are on by default. To turn them off:
