Concepts you described can't happen without a Step 1 in even approaching linear algebra. These types of explanations help many take that first step.
Right, my exact sentiment.

These kinds of explanations are so meh to me. Linear algebra is useful once you begin to look for vector spaces you didn't know you had.
Thinking of matrices as spreadsheets is barely abstraction. Seeing the derivative operator represented as a matrix, acting over the polynomial vector space can open your eyes.
Taking the determinant of that matrix shows that d/dx isn't invertible.
Thinking of the fixed point of the transformation yields exp, the eigenfunction of the operator.
I read it as a more intuitive primer on the subject, which I think it did fairly well imho.

I really enjoyed this, almost read as a primer in less academic order of operations and something more natural in the form of intuitive learning. Thanks for sharing!
It depends where you are in California. In parts of SoCal 100F is pretty typical. And the air quality is bad.
yeah air quality is terrible in Los Angeles when I visited there.

You are only accountable to yourself. 99% of goals are to impress people you don't even like. My only metric is to be a little bit better than my previous self, no matter how slow I go to achieve that.
Care to shine some light on some of those personal metrics you like to use?

This is true, studies have shown sharing an incomplete goal reduces your focus and motivation, as if you’ve already achieved it.
I find that if I post my high level goals publicly, I am more likely to complete them so people can see my progress. Anyone else?

While energy, and thus CO2, is a significant part of solar cell production (because of the sheer scale), the attributed CO2 output of the chip industry is tiny compared to the commercial value of the chips produced.
so carbon tax would be effective in this scenario?

If you knew enough VHDL you can make your own digital chips including CPUs using off the shelf FPGAs...

how steep is the learning curve for VHDL?
