What Open Source Commitment Actually Looks Like

For more than two decades, Joaquín López Muñoz has contributed to the C++ open-source ecosystem and maintained the work that eventually became Boost.Bimap.

His story began in Cáceres, Spain, in a house full of books.

At 13, Joaquín wrote his first computer program — and immediately knew programming would be part of his life.

Years later, a small side project exploring bidirectional maps grew into something much bigger. Joaquín submitted the work to Boost and discovered something he hadn’t expected:

People he had never met were actually using it.

That realization changed his relationship with the project.

“I’ve been maintaining the library for as long as it may take, and I will be doing that probably until the day I die.”

For Joaquín, that long-term stewardship is part of what makes Boost valuable. Libraries can remain dependable for decades because people continue maintaining them long after the initial excitement of creating them.

But historically, there was another reality:

“Nobody’s paying anyone to maintain a library. Not until the Alliance came in.”

Today, Joaquín also serves on Boost’s Fiscal Sponsorship Committee, helping represent the Boost community in its relationship with the C++ Alliance.

His story is about what open source actually requires: not just invention, but commitment.
