Rules for product managers at open source companies

Product management is an interesting career. It's immensely rewarding to be the interface between users, business strategy, engineering, and product design. And it's also a highly lucrative career with increasing demand for ambitious and empathetic practitioners. It's also a role with no single path. You might see various certifications and courses emerging to help address the serious skills shortage. The good news is that these are starting to contribute to the talent pipeline, but they struggle to address the wider demands of the role. This is especially the case where roles require direct experience across the enormous range of what it takes to build and ship successful products. Read more

How we decide when to release Fedora

Open source projects can use a variety of different models for deciding when to put out a release. Some projects release on a set schedule. Others decide on what the next release should contain and release whenever that is ready. Some just wake up one day and decide it’s time to release. And other projects go for a rolling release model, avoiding the question entirely. For Fedora, we go with a schedule-based approach. Releasing twice a year means we can give our contributors time to implement large changes while still keeping on the leading edge. Targeting releases for the end of April and the end of October gives everyone predictability: contributors, users, upstreams, and downstreams. But it’s not enough to release whatever’s ready on the scheduled date. We want to make sure that we’re releasing quality software. Over the years, the Fedora community has developed a set of processes to help ensure we can meet both our time and and quality targets. Read more

Raspberry Pi 4: Chronicling the Desktop Experience – Firefox Upgrade – Week 18

This is a weekly blog about the Raspberry Pi 4 (“RPI4”), the latest product in the popular Raspberry Pi range of computers. I’ve previously looked at web browsing on the RPI4 in Week 4 of my blog, recommending Chromium and Vivaldi on this tiny machine. Chromium offers the virtue of official Raspbian support on the RPI4 and it’s published under an open source license. On the other hand, Vivaldi is no-charge proprietary software. Both web browsers earned my recommendation. At the time, I was unable to recommend Firefox because the Raspbian repositories hosted a prehistoric version; version 60.9.0 ESR to be specific. Running a version of a web browser that’s 2 years behind the latest version is totally unacceptable, even from a security standpoint alone. Read more
