The “Well, that’s how we’ve always done it.” reason for not pursuing a new initiative should always be challenged. Gotta keep evolving.

Some advice from a senior engineer that stuck with me, recently:

“Don’t try to memorize everything. Learn where the docs are and bookmark them.”

Some concepts come easy. Some take time. But that "aha" moment? Worth it every time.
For me, recently, this was understanding TLS termination. What was your recent "aha" moment?

You sure "rsync -av" keeps files in sync? It only compares the file's size and timestamp. If content changes without either updating, it's skipped. The "--checksum" flag is the real truth-teller.

To all the "Getting Into DevOps" tutorials that don't have any modules on Networking ..shame on you. Networking is such an important foundation that gets skimmed over, or completely skipped, in a lot of tutorials.

Just had a power outage that took down my entire homelab. Recovery was… fun, and I got a first hand example of circular dependencies. Mini Thread 🧵

I broke my Longhorn deployment 🥴, which triggered a domino effect that disrupted several other applications in my cluster.

What’s an overlooked topic that many "Getting Into DevOps’" guides miss? In my opinion, it’s networking. Understanding the basics of networking can make a huge difference, when troubleshooting. Thoughts?
