Down the Linux rabbit hole (Friends)

December 12, 2025·1 hr 45 min·5 clips

Alex reveals why Podman's rootless mode creates a frustrating user ID shuffle that Docker avoids.

The Linux rabbit hole starts casually. A cold open moves through home lab chatter, sponsor energy, and a quick riff on agentic Postgres before the real conversation settles in. The pace stays loose. The host asks how someone goes from being known as a podcaster to producing content at Tailscale, and the guest backs up to explain it. Red Hat comes first. The guest talks about consulting in Europe, moving to the States, and working as a technical account manager for OpenShift customers. The job sounded fine and maybe a little boring when customers were happy. Weekly calls, support ticket follow-up, and value for money conversations gave it a very practical customer-facing shape. Then OpenShift changed underneath the role. The guest was there for the OpenShift 3 to OpenShift 4 transition, including the move from a RHEL-style base to an atomic immutable base OS image. That got complicated fast. CoreOS, Project Atomic, and re-architecture work stop sounding like buzzwords and start sounding like things customers needed help understanding before they landed. The host slows him down at the right moment. Instead of letting the resume carry the story, the question turns toward what the career shift felt like personally. The answer gives the episode its best thread. Technical account management and Apple Genius Bar experience both trained the same muscle needed for video: be personable, find the real problem, and explain it plainly. By the end, the show slips back into its familiar community mode with Zulip, home lab holiday talk, and sponsor thanks.

As heard by us

A loose Linux chat turns into a grounded story about infrastructure support, OpenShift migrations, and learning to explain technical systems clearly.

Once past the sponsor chatter about agent-facing Postgres and home labs, this episode settles into a practical career conversation about Linux work, support, and technical storytelling.
