I knew a little bit about the PANDA library but I'm learning a lot more.

Using the Graphical Modeler in QGIS 3.0
While I've written a handful of plugins in the past for QGIS, I've always wanted to learn about the graphical modeler which is a lot easier than writing all the Python by hand, especially creating the dialogs and setting up the methods yourself.
Resistance Dimmers
Believe it or not they had noisy, hot resistance dimmers back when I was in elementary school on the stage. They were original - from the 1930s, still in use 50 years later! They aren't that bad but at 50% dim of a 500 watt load they discard nearly 200 watts of heat per channel. At lower or brighter dimming they aren't nearly as inefficient. Very crude technology but reliable as witnessed by the fact they were still using 1930s technology in the 1990s.
