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
There’s a very specific kind of confidence that only shows up at 3AM. It’s the same confidence that makes you think: “This trade is obvious.” “Gas fees are fine.” “This smart contract definitely works.” Spoiler: none of those were true. The Trade That Looked Too Easy A few months ago, I was staring at a chart like I had just unlocked the secrets of the universe. IT looked clean. Too clean. “Perfec
I Sniped a Solana Token in 400ms — Here's the Full Tech Stack Sniping a newly launched token on Solana is a high-stakes game that requires precision, speed, and a deep understanding of the ecosystem. Recently, I successfully sniped a Solana token in just 400ms — and I want to share the exact tech stack and strategies I used to make it happen. This article will dive deep into Jito MEV bundles, Ju

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
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
Coming into Solana, I honestly expected blockchain data to feel abstract and complicated, like something hidden behind layers of cryptography that would be hard to reason about. In my head, I thought it would look nothing like the databases I was used to in Web2. But the reality surprised me. Once I started working with accounts and RPC calls, it began to feel less like “mystery tech” and more li
