I don’t see why developers make six figures, all they need to know is: - Linux - Bash - Go - Python - JavaScript and frameworks - Git - Docker - Kubernetes - Terraform - Distributed Systems - AWS - GCP - Prometheus - Grafana - Being On-call - Security

300+ signups already. I had expected around 50-60 tops. 🤪😱 Luckily the fact that it will be in Danish somewhat limits it from growing totally out of proportion 😉 – at Roskilde, Danmark

Why the need to *rely* on devs testing locally? I would go with automated pre-tested integration, and then (optional/on demand) review after integration, ideally synchronized team-review if possible. – at Roskilde, Danmark

60 students and recent graduates at the @SyddanskUni got the chance to learn the basics of DevOps tools such as #Git, #Docker, #Jenkins, with the help of @SofusAlbertsen @jankrag and some Lego exercises, during a 10-day summer course. #DevOps #ContinuousDelivery #summerschool

An entire thread full of gold nuggets... – at Roskilde, Danmark
Ancient sysadmin wisdom: don’t use ‘>’ as part of your shell prompt. You’re one copy/paste error away from truncating a file. There’s a reason root’s ‘#’ prompt gets interpreted as a comment.

Today, I am pleased to announce a bold and ambitious commitment: I change my diet to go 100% healthy food by 2050, and 45% healthy food by 2030 relative to my diet from 15 years ago when I was a college freshman.
