Learn how to review PR’s like an expert
Jan Rodák, Paul Holzinger, Matthew Heon, Neil Smith, Miloslav Trmač

When doing Open Source development code review is an essential skill, but how do you approach it like an expert? On the Podman project the community approves an average of 200 PR’s per month and has built up a large amount of expertise in reviewing code and would like to share our learnings.

In this panel discussion, we’ll explore PR reviewing from three perspectives: a beginner just getting started, an experienced reviewer, and a senior expert. Together, they’ll share insights on best practices, common challenges, and strategies for effective feedback. With a mix of pre-planned questions and audience Q&A, this session will provide practical takeaways to improve your PR reviews and level up your collaboration skills.

Play with Kube using Podman
Matthew Heon

One of the least-known commands of Podman is podman kube play, and it’s fantastic. It works as kubectl apply and supports the same objects but doesn’t need a Kubernetes cluster. It supports Pods, Deployments, Volumes, ConfigMaps, and many other Kubernetes resources and runs on Linux, macOS, and Windows. It has some additional features compared to kubectl, such as using local images.

This talk will discuss using podman kube play and its alter-ego podman kube generate to simplify Kubernetes’ first experiences.
