This week our co-worker, Allen Byrne (@byrn) retired from The HDF Group. We wanted to share what our fearless leader Gerd said at Allen’s retirement party. For context, Allen is a model train enthusiast.
Honestly, most of you haven’t worked with Allen that closely. But in a way, that’s kind of the point—because the best infrastructure work is the kind you don’t notice… until it’s gone and everything catches fire.
And if you’ve ever built HDF5 and thought, “Wow, that went smoothly,” there’s a good chance you have Allen to thank. He’s been one of the biggest contributors—especially on the CMake side— which is basically the part of the project where you don’t just write code… You negotiate with reality.
CMake work is like running a model train layout: it’s all about tracks, switches, and making sure everything connects properly—and when it doesn’t, you spend a lot of time crouched near the floor muttering things you can’t say in a release meeting.
But Allen kept the trains running. He made sure all the platforms lined up, all the signals worked, and the rest of us could pretend “it just builds on my machine” was a complete strategy.
So Allen, thank you for the commits, the patience, the behind-the-scenes brilliance—and for quietly preventing the rest of us from derailing the build system on a weekly basis.
We’re going to miss you a lot… which is also our way of saying: we fully expect the next build failure to be your fault in spirit.
Congratulations on retirement—may your days be full of smooth runs, zero missing dependencies, and trains that always stay on track.
Happy retirement, Allen!
