Thanks bud. Yeah I spent quite a bit of time on it. Really my series of articles are more about trying to document to myself what I'm learning. These more theoretical, mathematically oriented posts may not be incredibly interesting for someone just wanting a casual read. But it is great for me to refer back to it again and again. Hopefully someone else will.find it equally helpful

And yeah this is highly focused on fundamentals for sure. Good to be well versed on both sides :)
