I switched my home server from ARM SBCs to a $140 N100 (16GB) and honestly it's a real improvement.

I love the original concept of the SBCs


affordable and efficient, with hardware acceleration for compute-heavy tasks. But the reality for me lately has just been more trouble than it's worth, and running a mainline kernel on x64 is such a better experience. (I'm mostly griping at the Orange Pi I had


RPi tend to have better SW support.)

I like how modern is just sans serif Roman (+a few letters).

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.

The USA is huge, and individual states are huge. San Francisco and Los Angeles are both in California, but you're not going to do a day trip from one to the other.

Our beer is great! Probably stay away from the big brands (unless Sierra Nevada is considered a big brand


they're still great IMHO). Try to find something from a local brewery


it can be hit or miss, but more fun than finding one you like and sticking to it.

We have a lot of social services that aren't necessarily through the federal government. Food banks come to mind


some are "proof of assistance required," others are open to anyone who feels they need the service. There is not afaik a single interface for navigating these services though, so it can be a real pain, from what I've heard. But services often do exist, if you have the time to track them down.

Libraries! Free wifi is common.

If you don't like it here, try a different part of the country. Rural town in the south is completely different than a "blue city."

Bureau of Land Management.

It's government-owned land but it's generally free to use for camping. The USA is very big.

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.

The exorbitant PG&E charges are usually "delivery charges," not the "generation charge" iirc. So we're paying reasonable rates for cheap, clean energy, but we're getting charged out the ass for getting the electricity to our home.

It sucks either way, but charging for delivery sucks more because on top of it all if we run solar and sell back to the grid we only get the generation charge (which is minimal). At least, that's my understanding


we don't currently have a home solar installation.

It's overpriced hardware

Have you seen the M4 benchmarks?

If you're memory bound then sure, you can get way more bang for your buck with Intel/AMD. But for pretty amazing CPU performance I think the "Apple is overpriced" trope isn't really true any more.
