Back in 2018, we taught those DevOps concepts and implemented unbreakable pipelines for cloud-native delivery projects. Last week we kicked it off with a three-hour virtual hands-on workshop. The initial plan was to do it onsite in Ohio, but – I guess I don’t have to tell you why – we decided to start virtual first.

Before booting a compiled Linux kernel image on actual hardware, it can save us time and potential headache to do a quick boot in a virtual machine like QEMU. Also, QEMU has more flags than virtually any other binary I’ve ever seen (other than a google3 binary; shots fired), and simply getting it to print to the terminal is ¾ the battle.
