Ah, thank you, I see the argument. I'm still a bit skeptical though when many non-CVT automatics are 6 or 8-speed models that there would be much "sweet spot" benefit left by being able to make relatively small changes in eng

If overall efficiency is what you see reflected in the EPA mileage numbers (or similar European tests), in what scenario would a lower efficiency transmission (lower Pout/Pin over some range of operating points?) lead to or even allow

This is cool. I have a VW EV and use the B-mode for the "gas" pedal. It it not full one-pedal driving but IIUC exclusively uses regen. You can't decelerate rapidly, but most driving can be accomplished without touching the br

I have a Subaru (ten years old w/ >200k miles on it's chain-type CVT), and I thought the justification for it was that it was more efficient than previous systems. From a mechanical engineering standpoint, the Subaru CVT uses a

Nice work! I really enjoy learning how people did these experiments and learned such fundamental stuff with only "stone knives and bear skins"!

Too bad the joke doesn't work if you understand decibels.

Stargate wants to raise $500B not the paltry $500M as mentioned in the article.

One solution I haven't seen mentioned is trifocals. Progressive lenses used to be sold against bifocals and trifocals by saying "no lines" but there are some advantages to the old school designs. In particular, progressive de

Did you install GrapheneOS before or after the problematic update from google?

My guess is something about the waveform of the inverter is tripping up something in the power supply. Many moons ago I worked on laser printers and we had a customer who was melting fusers. Turned out their UPS had small but fast spikes ar

It's exactly how it works and the math is not complicated. Suppose you have a vehicle w/ 3 m^2 frontal area, drag coefficient of 0.3 and it's travelling at 30 m/s. Using this calculator https://www.symbolab.co

Force is proportional to square of speed but power = force*speed so proportional to speed^3.

Solid state means it doesn't use vacuum tubes. Well, that's what it used to mean.

Are there sound samples anywhere?

One of many reasons to despise Reagan. I was promised we would go metric and he cancelled it.

I will also say, a number of times I've thought something like "why would they do that?", and some months later (I'm kinda slow) I would realize that it now makes sense.

You've probably found this already: https://docs.julialang.org/en/v1/manual/noteworthy-differenc... That's the only "official" python-julia resource I know of although I bet there are some

The first problems I came to Julia to solve were ODE simulations in which it's just as critical that the stuff I write and rewrite over and over again (the actual differential equations of my model and associated simulated controller c

If you specify a distribution using, say, Float32s, you'll get a distribution in Float32s. I'm guessing the machine learning example used Float32s so they would better take advantage of a GPU. It's almost always true in Julia

Why did you write all those anonymous functions? You can just do a |> b |> c|> d |> e although there are style guides that discourage that and instead recommend using a line for each with good temp variable names.

Yes, they went to INCREDIBLE lengths by, umm, spending a number of years creating an excellent language which drew enthusiastic folks who created INCREDIBLE packages on top of that base. Seriously, when I learned Python (about 20 years ago)
