Hello,

This is the SadServers bulletin, featuring new hands-on challenges to help you build and strengthen your Linux and DevOps skills.

New scenarios since the last newsletter:

• "Philadelphia": htop metrics disagree - Inspired in this excellent htop explained article.
• "Luxor": PostgreSQL analytics queries crawl - A database optimization challenge, using a pretty standard strategy.
• "Banha" : Intermittent 504 Gateway Time-Out errors - Intermittent error situations are fun (see Heisenbug), try out this Nginx+Gunicorn scenario.
• "Aswan": K8s Service Connectivity Failure - Debug Kubernetes connectivity between two pods.
• "Nairn": Phantom Gitea Deploy - This challenge introduces a problem with Gitea, a self-hosted CI/CD tool,
• "Vienna": The Vanishing Process - Because there's never enough systemd/journalctl scenarios if you want to master Linux.

If your company is interviewing for Linux/DevOps/SRE or similar positions, you may be interested in our Business solutions, contact us for any questions.

Remember that if you have a professional development or training budget at work, you can ask them to pay for your Pro+ plan with a simple one-time payment, just direct them to our Gift page

 

Thanks,

Fernando Duran
