I teach information technology at the community-college level in Central Texas. My classroom blends structured curriculum with a relaxed, community style — a lot like troubleshooting a vintage radio while sharing a plate of gumbo.
When a platform update breaks a thousand identical PCs, the fix isn't a newer certificate or a bigger hammer. It's tracing the signal path one stage at a time. That's the whole of my teaching, whether the stage is a vacuum tube, a network switch, or an emulation layer.
New: The ARM Wall
When Outlook and Teams went dark on ARM-powered PCs this week — same app, same Friday, but only the Surface machines broke — thousands of IT desks lit up. My new short film traces the signal path: why the emulation layer is the fault, and the three things to check before you reimage the box. It's also on my 4ort.mov channel.
