Why does EVPN/VXLAN exist? The problems that broke the old way
EVPN/VXLAN didn't appear because engineers wanted more acronyms. It appeared because the old network model broke under the demands of modern data centers.
When automating triage quietly costs you money
I measured AI triage on 1500 closed GitHub issues across three real codebases. The cost case is real. But on one repo, automating would have silently mislabeled one issue in three — and the accuracy number gives you no warning.
Can AI Lower the Cost of Starting Over?
We keep asking which jobs AI will replace. Maybe the better question is whether AI can lower the cost of changing direction — and make starting over survivable.
Whose Walk Is It?
We used to walk without a destination. Now we walk 10,000 steps to close a ring. The walk is the same. But something is different.

You have a family, a mortgage, obligations. But what would it actually cost you to change direction? Maybe the problem isn't income — it's the structural risk of being wrong.
The Knowing
At the gym I saw teenage boys loud in the hot tub and a quiet man alone in the cold plunge. The strange thing about growing up is you can't see it from the inside — only in mirrors you didn't look for.
AWS Well Architecture Framework
The AWS Well-Architected Framework is basically AWS handing you a checklist so you don't forget the important details. A walkthrough of all six pillars with practical exam tips.
Swappable LLM Architectures: Building Flexible AI Systems
Building applications tightly coupled to a single LLM provider creates technical debt. Here's an interface-based architecture pattern that lets you switch providers without rewriting your codebase.
Automation vs AI Workflows vs AI Agents: Understanding the Differences
Automation, AI Workflows, and AI Agents are often used interchangeably — but they represent fundamentally different levels of autonomy. A clear breakdown to help you choose the right approach.
