This technical post walks through the design and implementation of Secure Playground: a local web app that simulates prompt-injection attacks against large language models and demonstrates simple defenses. Provide a minimal, reproducible environment to test payloads and defensive strategies. Make it easy to add new providers and run mutation-based red-team experiments. Offer a leaderboard and scor

Monday morning, one engineer was out on PTO and three separate workstreams were already blocked before lunch. Slack filled with "quick question" pings nobody else could answer, and standup turned into a scavenger hunt for missing context. By Wednesday, it was obvious we did not have a throughput problem ... we had built a system that stored critical knowledge in one person. Most leadership teams d

This is Part 1 of a two-part series. Part 2 (coming soon): Connecting to spoke clusters from a controller using multicluster-runtime, driven by ClusterProfile. The Cluster Inventory API (multicluster.x-k8s.io) is driven by SIG-Multicluster and centered on the ClusterProfile resource. It only delivers value when something produces those ClusterProfiles. That something is a cluster manager. Today, t
When developers travel, we usually prepare the obvious things. Laptop charger. But there is one dependency that is easy to underestimate until it breaks: mobile internet. A trip to China makes this especially obvious. Not because China is hard to travel in, but because so many basic interactions are mobile-first: navigation, translation, ride-hailing, hotel communication, ticket confirmations, pay
A defaced website is a curious problem. It's loud — anyone visiting the page can see something is wrong. But it's also quiet from a server's perspective: HTTP returns 200, your uptime monitor is happy, your TLS cert hasn't moved, and the CMS logs show a "successful" content update from a legitimate-looking session. The signal is on the rendered page, not in the metrics. I run a site at hi3ris.blue
Do you say "Goodbye" to your coding agent at the end of a session? Even though we (should) realize that we're talking to a very complicated mathematical engine, it can be hard to resist the urge to perform the rituals of human interaction, and maybe you even feel bad for just exiting the session without saying goodbye. I remember a particular session where at the beginning I was feeling very str
