Hi everyone, my name is P Swyom Sanjog. Welcome back to my blog—I hope you’re all doing well. Today, I’m bringing a new topic: Virtual DOM. Let’s understand what the Virtual DOM is in simple terms. We’ll cover key questions like what it is, why it’s used, and how it works. So, let’s get started! Virtual Dom So, let’s break down the topic into “Virtual” and “DOM.” Virtual means something that exi
Your phone will connect to the strongest tower it hears. It does not ask for ID first. It assumes trust, and that assumption is the entire problem. I first noticed this in 2019 outside a security conference in Las Vegas. My test Android dropped from LTE to 2G for 47 seconds, then returned to normal. No user notification. The baseband logs showed a cipher downgrade to A5/0, a location area code tha
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

What is Maven? => Maven automatically downloads required libraries from online repositories, so developers don’t need to manage JAR files manually. It follows a standard project structure, making projects easy to understand and maintain. => Maven also manages the build lifecycle, including compile, test, package, and deploy phases. Overall, Maven simplifies development by handling dependencies, b

Introduction Wormhole4j is a Java implementation of the Wormhole index, an ordered in-memory data structure from the EuroSys '19 paper, "Wormhole: A Fast Ordered Index for In-memory Data." By using the strengths of hash tables, prefix trees, and B+ trees, it achieves a worst-case lookup complexity of O(log L), where L is the length of the key. This makes it very fast for both point lookups and r
