Reminds me of the Bluey episode where Bandit takes the kids to the pool by himself and forgets all the basic shit and Chilli comes along and saves the day

Okay, yeah, greater or less than 50 seems to be the goal, thus I would have recommended thresholds.
The weird gradient threw me off, and I'm sad I spent more brain cycles on it than I should have. It would be cool to not abuse color like this 🫶

Or if <50 vs >50 is the goal here, a binary threshold

Would not a uniformly varying gradient serve better?

I have questions about your color scheme. It *very strongly* accentuates differences in the 47-50% range while flattening differences above 50%. What is the purpose of this choice? It weirdly calls out WY and ND, though they're barely different from WV. And 51 to 70% is barely noticeable 🤷

Of course that argument makes them look bad, so instead we get it by innuendo: Lee killing US soldiers to support his state's defense of *slavery* is 'good,' but folks in LA protesting in support of their state's defense of immigrants is bad.
Left unstated: because racism.

Another unexpected result of the mysterious and arcane math involved here, when you could previously spend $100 to get 100% of a thing, you will now spend $100 to get $100÷$130=76.9% of a thing, meaning your money goes 23% less far!

I'll go out on a limb and conjecture: 3.3uW is the power draw for all non-maths "support" functionality, active alone most of the time, thus the "typical" draw, while 10.5uW-3.3uW = 7.2uW *is* the power required for the math itself—clocking, register juggling, adders, etc. Thus 7.2uW*0.15s = 1.1uJ

why would you manually kern caps Times New Roman based on the serif edges??? I’m gonna lose my mind and so is god

Hmm, 3.3uW appears to be the quiescent (standby power) given the supply current in WAIT mode 2.2uA x 1.5V. In OPERATE mode, the draw is higher, 7uA x 1.5V = 10.5uW. So my crude calculation above becomes 10.5uW x 0.15s = 1.6uJ 🤷

And 3.3 microwatts includes *all* the functions of the IC, including I/O like capturing button presses and segment display, managing memory, and so on. The amount used for only the maths will be less, probably a lot less.

Page 7 shows the duration of various operations, a basic multiply taking 100~200ms. Crudely, 3.3e-6 x 150e-3 gives you 0.50 microjoules.
Getting more precise will require the I/V waveforms clocking through the registers over this calculation, which we don't have here. But this is pretty close.

I thought of @justingarrison.com and @withenoughcoffee.com as I was writing this. I just found your new podcast and have to catch up!

Cool! Thanks for this history. I really liked this film
