<p>The early-career perspective here is so valuable! I love the way they explain everything, and the extension on their project is really nifty.</p>

<p>I enjoyed the evaluation of AI agents in the frame of control theory and Ashby&#8217;s law. When your control system is incredibly complex, it can be hard to reason about what it does.</p>

<p>Here&#8217;s a good one to dig into from GCP. It&#8217;s especially interesting to see what they knew when they wrote their preliminary report vs their final report.</p>

<p>There&#8217;s a really cool idea in this article and the original post it refers to: overlaying histograms to show how a latency distribution has changed over time. I&#8217;m still wrapping my head around the kernel density graphs, though.</p>
