SysAdmin Weekly Newsletter Issue #19: Trust, but Verify the Abstraction

[asyrewicze]

Issue #19 of our SysAdmin Weekly Companion newsletter is live @ https://newsletter.sysadminweekly.com!

This issue ties into the abstraction discussion from last week's podcast episode and specifically calls out a storage issue I had where abstraction stops being helpful and starts lying instead. In short, I had a Kubernetes storage issue that forced me to stop trusting the dashboard and go back to first principles.

Also covered:

• Why you probably don't need 10 Gbps fiber at home
• A smarter way to think about GitHub Copilot
• A small terminal tool I rebuilt to reduce context switching when elbow deep in the terminal

Speaking of abstraction issues......I’m curious:

• Have you been burned by abstraction hiding critical details?
• What’s the worst “everything looks fine” incident you’ve dealt with?

Drop your thoughts or war stories below. This feels like a shared pain point.
