Learn AI Series (#112) - RL for Games What will I learn You will learn AlphaZero -- the single algorithm that mastered Chess, Go and Shogi with nothing but the rules and a stubborn habit of playing itself;

Learn Zig Series (#93) - SOCKS5 Proxy What will I learn? What a SOCKS5 proxy actually is once you strip the mystique away -- a tiny handshake, a one-shot connect request, and then dumb byte-copying in

Learn Ethical Hacking (#71) - Hardening Linux - From Default to Fortress What will I learn Why defaults are dangerous -- what a fresh Linux install exposes and why every service is an attack surface; User

Learn AI Series (#111) - Multi-Agent Reinforcement Learning What will I learn You will learn the three flavours of multi-agent RL: cooperative (shared reward), competitive (zero-sum), and mixed (a bit

Learn Zig Series (#92) - gRPC Service in Zig What will I learn? What gRPC actually is once you strip the branding away -- protobuf payloads, HTTP/2 transport, and one small calling convention bolted on
