Q. What is a Linux sysadmin’s favourite hangout place? A. Foo Bar Share your favorite Linux/IT joke 👇

Vim has two modes: Insert mode and panic mode.

Rome wasn’t built in a day Because they didn’t have Claude AI in those days 🤣

@0xGooseOps The way it is going, they could become better at troubleshooting in near future.

@LinuxHandbook Agents are going to be the tipping for DevOps. Automation is fine with the scripts from llms but a lot of troubleshooting is manual digging. Agents can do some of this but they will have to get better and more trustworthy.

Most pessimistic views see the end of coding in the next couple of years. How do you see the impact of AI on DevOps?
