No, but I think it’s good when someone with credibility among certain people reiterate something, even if it adds nothing of value to you and me.

Democratic and left-of-center politicians (or “liberal elite economists”) can say this until they’re blue in the face but Trumpers will dismiss it as I dunno, woke butthurtism or something. But when someone like Buffet says it, at least they (maybe) have to think a little bit before coming up with some mental gymnastics to dismiss him. And maybe along the way they’ll question, if only a little bit, the sanity of Trump’s policies.

Some bulk food stores let you bring your own. You put a sticker on them with the bulk item # and also the dry weight, so it’s a little more work, but then you can put your jars to use!

Newer macOS is not Unix certified.

It’s UNIX 03 compliant https://en.m.wikipedia.org/wiki/Single_UNIX_Specification

One or two Linux distros were (are?) UNIX certified, though.

Haha yeah that was the counter example I was thinking of. I agree completely — you could make a Gentoo from source beginner distro, and I think you could make it reasonably “idiot proof,” but it would still be a bad user experience most likely (too much time spent compiling).

If your distro can’t be forked into a “beginner distro” then it’s fundamentally flawed IMHO.

To be clear, I’ve used Arch as my daily drivers for a while, and while it’s not the best fit for my needs (I use Debian mostly), there’s nothing that I experienced that was incompatible with a “beginner” distro.

One thing to keep in mind — the US is huge, both geographically and culturally. Flying from Los Angeles to Boston is further than London to Baghdad.

And likewise, the cultural “distance” between, say, New England or the Pacific Northwest and the deep south is extreme.

Of course there are things that affect (nearly) all Americans, but some context is important.

But this applies to the UK, Ireland, France, Belgium, Italy, Spain, Portugal, and…well…much of the world, if these data are to be trusted.

But “included” doesn’t mean free. You still paid for it.

Baking is chemistry, cooking is jazz.

I’m curious how the battery percentage went up

Physicists hate this one weird trick…

Is that true though? As in, is it really that dangerous? It seems that you’ll dissipate power equal to the inefficiency times the nominal charging power, so something like 5V x 2A x inefficiency (inefficiency being 1-efficiency), which will probably be of order a watt.

I can use my car battery to charge itself without any issues — I just plug the red terminal to itself, and same with the black, which is to say, a battery is always connected in a way that “charges itself.”

I think the key is that the battery probably isn’t really playing a big role in OOP’s setup — electricity doesn’t “go through the battery,” it just goes from the charging input to the power output circuits, with the additional power (due to inefficiency) being provided by the battery.

I’m not sure though — the power output and the charging input are both regulated and (almost certainly) current limited. So I think (not positive…) that you’re basically dissipating your power in the inefficiency the charging and output circuits, with this power coming from the battery.

The inefficiency should (I think…) just be the round-trip inefficiency of the charging/discharging of your power bank — this should be way, way less than the short-circuit power dissipation.

The simplest toy model is to take a battery and try to charge itself. So you put jumpers on the + terminal and you connect those to the + terminal, and same for - (charging is + to +, NOT + to -). But this is silly because you’ve just attached a loop of wire to your terminals, which is equivalent to doing nothing. With charging circuits in between things get much more complicated, but I’m not sure if it goes full catastrophic short…

For those wondering about the energy, not just the power:

When fully charged, the upper reservoir can store enough energy to power the plant at full capacity for 10.8 hours, equivalent to nearly 40 GWh.

For 75kg (roughly average South Korean male weight) and 7" step height (standard in the US I think, not sure about Korea), this is about 0.13kJ/step.

By coincidence, the human metabolic efficiency is (roughly) the same as the conversion between kJ and food (kilo)calories, meaning this would be (very roughly) 0.1 calories/step.

Not much, given a single French fry is maybe 5-10 calories. But it’s better than nothing!

good enough simulations that you can’t tell the difference.

This requires us having actual conversations with those dead people to compare against, which we obviously can’t do.

There is simply not enough information to train a model on of a dead person to create a comprehensive model of how they would respond in arbitrary conversations. You may be able to train with some depth in their field of expertise, but the whole point is to talk about things which they have no experience with, or at least, things which weren’t known then.

So sure, maybe we get a model that makes you think you’re talking to them, but that’s no different than just having a dream or an acid trip where you’re chatting with Einstein.

Isn’t universally funny.

My city has a fleet of vintage streetcars that it runs on standard routes (i.e., it’s not just a tourist novelty — and it’s the same cost as bus and other light rail).

It’s always a joy to ride those and read the history of the individual streetcar — they all wear fun livery.

Our home averaged 7.5kWh/day in December (we did not travel and we’re home with family the entire time); this is about 10x less daily energy than the battery capacity of a modern EV.

Now, we have gas heating and stove/oven, so that adds a huge amount of load — but my numbers above are for 24hr energy, and batteries wouldn’t need to supply that whole time.

Of course, this doesn’t address cost, and it doesn’t address natural resources, like you mentioned. But that actual required amount of energy per capita can certainly be achieved with current battery technology.
