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
The most popular HTML, CSS, and JavaScript framework for developing responsive, mobile first projects on the web.
A 16-pixel hero in your macOS menu bar. Watches LLM traffic. That's it. You remember RunCat — the kitten in your menu bar that runs faster when your CPU is busy. Almost a decade old. Adorable. Useful. Asks nothing of you. AI-native development needs the same thing for a different signal. Not CPU. Agent traffic. Is there a live LLM request flowing right now, or is everything quiet? That's why I bui

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
As a developer, you deal with text casing constantly - button labels, nav items, page titles, error messages, documentation headings. And at some point, someone on your team will ask: Here's the definitive answer. // Title Case — most words capitalized "The Best Free Tools for Writers and Developers" // Sentence case — only first word + proper nouns "The best free tools for writers and developer
We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin
