- Google AlphaEvolve Goes Public: The AI Agent That Discovers Better Algorithms Than Humans Can WriteGoogle’s AlphaEvolve is now generally available on Google Cloud. The evolutionary coding agent discovers algorithms that outperform human-written code. Here’s how it works, who’s using it, and why it matters.
- TypeScript 7.0: The 10x Faster Native Rewrite That Changes Everything
TypeScript 7.0 is a native Go rewrite delivering 8-12x faster builds, 18-26% less memory, and near-instant editor startup. Here is what changed, real benchmark numbers, and how to upgrade. - JADEPUFFER Explained: How an AI Agent Ran a Ransomware Attack Without Any HumanJADEPUFFER is the first documented AI-driven ransomware operation with no human at the keyboard. An LLM agent exploited Langflow, stole credentials across 6 categories, pivoted to production, corrected its own errors in 31 seconds, and encrypted 1,342 records autonomously.
DIY Engineering by VKP
I build open-source hardware and software projects — from custom CNC post-processors for LinuxCNC to embedded systems with STM32, motion control with stepper motors, and smart home automation with ESP32. This is where I share what I learn along the way.
