I have to bring back an oldie but a goodie...because let's face it: Sometimes #XKCD just nails our industry. Still relevant and probably always will be!

I can’t believe how fast this semester went. Teaching Linux Administration at #JCCC has been one of the highlights of my year.

Watching students go from “what’s a terminal?” to confidently managing services, firewalls, accounts, and networks never gets old.

Huge shoutout to my students — thanks for showing up, asking great questions, and pushing yourselves. Can’t wait to do it again.

I spent last week rebuilding my entire setup — migrating from #Unraid to #Proxmox.

New storage layout, new VMs, new containers, new automations.
It’s amazing how a clean slate can simplify everything and spark new ideas.

Still tweaking, still optimizing, but honestly? Feels good to be back in the #hypervisor world.

Any of you doing winter homelab overhauls right now?

If you’re troubleshooting a weird network issue and nothing makes sense, try this combo:
dig +trace example.com

It walks the entire DNS resolution path — root → TLD → authoritative — and shows you exactly where things fall apart. It’s one of those tools that turns “I have no idea what’s going on” into “oh, there it is.”

What’s your go-to DNS troubleshooting command?

Friday Reflections:

Someone gave me great advice recently:
Each night: shut off your phone, meditate, take a hot bath, and fall asleep with an audiobook.

It’s simple, but it’s helped me wind down, rest deeper, and reset for the next day.

IT work (and life) can be chaotic. But the quiet moments, the ones we choose to protect, make all the difference.

What’s one habit that helps you recharge?

Tech Tip Thursday!

Encryption isn’t just for spies, haha, it’s for sysadmins too. 😉

Three easy wins you can start today:
* Encrypt /home or sensitive directories with LUKS or eCryptfs.
* Use GPG for signing and verifying packages or configs.
* Enable HTTPS and TLS for every service that touches the internet.

Security isn’t about paranoia; it’s about preparation. How are you using encryption in your daily workflow?

Question for my fellow IT pros:

What’s one small thing you’ve done that made your systems noticeably more secure or stable?

Could be an alias, a config tweak, a tool, or a habit.
Sometimes it’s not the big overhauls that save the day but the five-minute fixes.

I’ll start: teaching students how to lock down SSH access properly has saved me hours of future troubleshooting.

Taught about host security last week! Here are a few essentials:
🔒 Default-deny firewalls (ufw or firewalld)
🧰 Disable unneeded services
🖧 Use SSH keys, not passwords
📊 Watch /var/log/secure for odd activity

Host hardening is your first defense, not your last.
What are your goto tools?

Account security on Linux starts simple: principle of least privilege.

A few quick checks:
1) Ensure no one logs in directly as root
2) Use sudo with proper group assignments
3) Enforce strong password or key policies
4) Monitor failed logins via /var/log/secure or journalctl

Small habits prevent big breaches, especially in shared environments.
What’s one account security tip you wish you’d learned earlier?
