AI made writing automation cheap. It did nothing for running it.

A model will hand you a working playbook in seconds. It will not tell you who's allowed to run it, against which inventory, with which credentials, on what schedule, or what happens when it dies halfway through 200 hosts. Authoring dropped to near zero but operating it didn't move.

That gap is widening: the more playbooks get vibecoded, and the more agents start firing them off on their own, the more you need a layer that decides what actually executes, with what privileges, and leaves a record when it does. That layer is AWX.

So I released a book about it. AWX in Action: Ansible Orchestration at Scale (expanded edition) is the practical guide: deploying AWX on Kubernetes with the operator, wiring up projects, credentials, RBAC, workflows, and execution environments, scaling past a single node, using the CLI, understanding the settings and much more!

The book is the half AI won't write for you. It's already the #1 Hot New Release in Distributed Systems & Computing on Amazon, which tells you how many people are stuck on the operating half.

You ran "kubectl get pods" before your coffee was even ready. Again. Might as well drink it from something that gets it.
This is a heavyweight black ceramic mug for engineers who live in the terminal. Matte black, solid C-handle, 11oz of room for whatever fuels your on-call shift. Microwave safe, dishwasher safe, and tough enough to survive a Monday outage.

Grab yours because the cluster never sleeps, and neither should your caffeine.
Order now, ships in 2-9 business days.

Most developers don't actually understand Git. They memorize four commands, copy-paste the rest from Stack Overflow, and quietly panic every time a merge goes wrong.

This course fixes that. Learn Git in a Day - The Visual Guide turns branches, merges, rebases, and resets into clear pictures you can hold in your head, so you finally know what's happening instead of hoping it works.

One focused day, and Git stops being the tool you're afraid to touch.

SREs should study how engineers keep systems reliable during routine work, including the adjustments they make before incidents occur. Tech teams have adopted Safety-II at a limited rate because they lack practical models for observing those adjustments.

Intel designed Crescent Island, an AI inference GPU, with lower-cost memory and air cooling, and plans to ship limited quantities this year.

A researcher disclosed CIFSwitch, a Linux local privilege escalation flaw present since 2007. Unprivileged users can exploit the CIFS Kerberos mount helper to gain root access.

AWS security teams define npm supply-chain defense as two tasks: limit credential blast radius and block unverified artifacts before production.

DevOps metrics show how fast & reliable your team delivers software; valuable for saving money & building trust. DORA metrics only part of the picture. Focus on key categories to understand if overall delivery is improving. Don't just measure, find the bottleneck for real improvement.

Did you know that systemd, the program that starts and supervises services on most Linux distributions, has a built-in watchdog where a service reports its own health from the inside rather than being probed from outside? Through a small protocol called sd_notify, a process signals that it is truly ready only after its own checks pass and then sends periodic heartbeats; if those stop arriving within a configured window, systemd restarts it, and the process can even request extra time mid-startup so a slow cache warmup or filesystem check does not trip a hard timeout. The takeaway is that the most reliable health signal usually comes from the process itself, not an outside observer guessing from an open port.

"When you can replace any server in minutes, you start treating every outage like a rounding error. Cloud and DevOps didn't remove failure; they made failure cheap enough to ignore until it isn't."
