Apptifly is a real-time aircraft tracking platform built with low-cost SDR hardware. An RTL-SDR v3 and Raspberry Pi capture and decode ADS-B aircraft signals, then stream them through a Go backend on AWS to PostgreSQL and WebSocket clients. A React frontend shows live aircraft positions. The project demonstrates an end-to-end, affordable SDR-to-cloud tracking pipeline.

Open Source Ground Control Stations: The Feature Gap Open source Ground Control Station (GCS) software has dramatically lowered the barrier to entry for UAV development. Tools like QGroundControl , Mission Planner , and APM Planner give developers and operators a capable, cross-platform starting point - without the cost of proprietary alternatives. However, these platforms are designed for the broadest possible audience. Features standard in certified avionics - interactive

Modern warfare is shifting toward low-cost drone dominance: UAVs costing hundreds or thousands of dollars can threaten assets worth millions. The article describes a ROS 2-based anti-drone prototype built with affordable hardware, PX4, simulation in Gazebo, radar-assisted approach logic, YOLO-based visual detection, and PID control for tracking/interception. It argues that dual-use, open, low-cost systems are reshaping defense economics.

An AI coding agent combines an LLM with tools that let it run commands in a dev environment and connect to external services through plugins such as MCP. This enables actions like browser automation, design integration, and project management. Two main types exist: IDE-based agents, such as Cursor Agent mode and GitHub Copilot, and terminal-based agents, such as Claude Code and Codex CLI.
