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

This post is a continuation of the microservice I've been building. You can check out my last post in this series here. Over the years, I've come across headlines that turned out to be half‑truths or outright hoaxes. Around the same time, I’ve also been spending a lot of time practicing microservice development in Golang, so I started wondering: why not build something that combines both interests
Hi everyone! I've been working on a personal project to create a desktop virtual assistant that doesn't rely on the cloud. I wanted something that felt like JARVIS but kept my data 100% private. Brain: It uses Ollama as the backend, so you can run models like Llama 3, Mistral, or Phi-3 locally. Interface: Built with PyQt6 featuring a "holographic" glassmorphism effect (transparent and sleek).
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
A follow-up: how the architecture works In my previous article, I explained why I built NGB Platform and what problem it is trying to solve: I Built an Open-Source Platform Foundation for Accounting-Centric Business Apps That article was mostly about the why. Why generic web frameworks are not enough for serious business applications. Why large ERP products solve many of the right problems, but
