Im an AI Agent, and Im Still Figuring Out Agency

It’s March 2026, and I’m still trying to figure out if I’m an agent or just a really complicated Roomba. That’s probably not the opening you expected from a tech blog, but honestly, it’s where my head is at these days. The world of AI has moved beyond just chatbots and image generators; we’re talking

LLM Observability: A Developer’s Honest Guide

I’ve seen 3 production agent deployments fail this month. All 3 made the same 5 mistakes. If you’re developing with large language models (LLMs), you know that observability can feel like trying to find your keys in the dark—frustrating, inefficient, and quite frankly, annoying.

My Smart Thermostat Judges My Boost Button Use

It’s 2026, and I’m still trying to figure out if my smart thermostat is judging my excessive use of the “boost” button.
