The Model Context Protocol has transformed how we connect AI to tools. But connecting agents to tools is only half the battle — connecting agents to each other is where the real challenge begins. I recently read @raviteja_nekkalapu_'s excellent article "I built an AI security Firewall and made it open source because production apps were leaking SSNs to OpenAI" and it resonated deeply with challeng

Japan's Subcontracting Act (Toriteki-ho / 取引適正化促進法, commonly called 下請法) governs transactions between large businesses and their subcontractors. It mandates specific payment terms, required contract clauses, and prohibits certain business practices — and violations carry significant penalties from the Fair Trade Commission.

Why MySQL Dumps Don't Import Directly into PostgreSQL users ( id INT(11) NOT

Introduction Code reviews. For many developers, they are a necessary evil — a box to check in the development process. However, I have come to appreciate them as a powerful tool for elevating code quality, fostering collaboration, and improving team dynamics. Today, I want to share my journey from viewing code reviews as a mundane task to recognizing their critical role in successful projects. L
