An update on Circadian Rhythms, F.lux, and DDC/CI (i.e. part IV)
I’ve made a number of minor changes in the C# code from part three, fixing a few bugs and cleaned up the code. Scroll down for the binary + source code.

In other news, I’m making considerable progress on the Visual C++ version – A few months ago I successfully implemented the DDC/CI functions! I’ll move all code to a GitHub repository at some point.
