Industrial Robotics in 2026 The industrial-robotics world in 2026 is less science-fiction than the AI headlines imply and more capable than the conventional wisdom expects. We walk what is actually on factory floors, the ISO 10218 and 15066 safety standards that shape cobot design, force-limited collaboration, the integrator economy that decides whether a robot ever ships, and the honest gap between marketing and deployment reality.

PID Control from First Principles PID is the feedback loop that runs an enormous fraction of industrial reality, from thermostats to flight control to chemical plants, and almost every interesting behavior of a real plant can be predicted by understanding what its three terms each do. We walk the math, the intuition, the tuning, the standard failure modes, and the honest gap between the textbook controller and the one that actually runs.

PowerShell for Administrators The automation language Windows admins cannot avoid, for engineers fluent in bash: the object pipeline and why it beats text streams, cmdlet naming and discovery, remoting with WinRM and SSH, working with Active Directory and the registry, modules and the gallery, error handling and scripting patterns, and PowerShell on Linux. A pragmatic onramp that respects what you already know from the shell.
