Session: Fixing The Open Source Bus Number
Speaker(s): Sanne Grinovero & Holly Cummins
Date/Time: Thursday March 19, 2026
Abstract: Open source is a marvellous multiplier which amplifies our collective productivity by allowing us to code on the shoulders of giants. It has clear benefits for business continuity.

But things can go wrong. Many critical projects have just one or two maintainers (we’ve all seen the xkcd cartoon about modern digital infrastructure, haven’t we?). Sometimes those maintainers no longer have time, or burn out. At the other end of the spectrum, even projects with many active contributors can grind to a halt with the contributors all work for the same employer, and that employer changes their business priorities. Investment can dry up or the licence can change. After all, the business environment for open source is tough these days.

What can be done?

The classic solution for increasing a team’s bus number is to use pair programming to share knowledge. In the asynchronous and distributed world of open source, pair programming can work, but it’s harder – and it can’t fix changing business realities or hostile licence changes.

This talk will discuss some of the strategies used by the Quarkus team to help ensure our open source community is prepared … for almost anything. These include

• Using GitHub organisations to allow independent contributions with a ‘safety’ backup if maintainers disappear
• Productising dependencies so that anything in the stack can be rebuilt to address vulnerabilities; this helps with security, and also helps with investment
• Joining the Commonhaus foundation to ensure Quarkus can’t ever be owned by a single company

Some of these have been easy, some have been tough (the logistics of moving to a foundation are not for the faint-hearted). In this talk, Holly and Sanne will reflect on what’s worked well, what’s transferrable, and how all of us can be prepared for the future of open source.
