subdomains are not sufficient, unfortunately. I think the instance I'm thinking of is technically web/https (chrome's site safety feature where you can specify a domain as 3rd party content- so when something gets flagged uour entire domain doesn't get blacklisted)- but it's much easier to just grab another domain

I think the point is that subdomains are fine, assuming you ARE using a separate IP address for said subdomains.

The majority of my spam from established companies are on subdomains of their main domains. Are they doing it wrong?

wafers are the easy bit.

everybody also ignores that even hello world isn't deterministic anymore. It just doesn't matter to execution if something broke unless it kicks back an error.

although, this is the best example of how quickly a trivality can knock so called "correct" programs over.

it seems iOS will drop previews into an unencrypted section. which, Is how I expected iOS notification previews to work without unlocking the phone

Alec presented it well- but we don't even need to take his word for it.

The Department of Energy has all the data available, so do a dozen different other private and public institutions. It didn't click for me till I ran some napkin math.

For arguments made in good faith- I think it's humanity's inability to comprehend scale. We can't get the volume of a glass of water right if we change it from tall to wide. Why would we think that terrawatts worth of PV would be a square shorter on a side than most people's daily commute?

Horrifically pessimistic numbers for PV (winter in maine with conversion efficencies half what they are now)... comes out to about a 50x50 mile square of panels to generate the entire USA's power demand from the most recent DOE numbers. Ignore that we can have wind, solar, and crops* in the same area. Turns out, btw, crops don't like high noon beating down on them. As a result we can reduce water usage and get nearly the same crop yield if part of the field is covered with panels- at least according to some studies.

That isn't the whole story. At least some of these new datacenters are gigawatt class. That's multiple sq km of solar.

Water usage is also an issue. A continuous 1 gigawatt is enough to boil off 1.3 million liters per hour which over 24 hours equates to very roughly 90k residential users. If it isn't boiled but is instead returned lukewarm it will require many times that amount due to how large the heat of vaporization is. Compare to the entire state of Florida at "only" 23.5 million people.

What? The water is not getting boiled off. Datacenters, for the most part, have closed liquid loop cooling systems. Electricity goes in, hot air and bits come out.

The old datacenters had. I don't think anyone is air cooling (radiator or otherwise) a gigawatt. Convert 1.3 million liters per hour from boiled water to air and you get an absurd number.

did you move the goal post, or erect a new one? either way- residential use is penny ante in terms of water usage. So much so that comparing data center use to residential use without including industrial, commercial, and irrigation can only be in bad faith.

Particularly since usage reports typically present all the numbers in the same chart or grid.

The concern is resource usage. Water had been left out, so including it isn't shifting the goalposts given the context.

The comparison was intended for illustrative purposes. Residential usage provides something relatable and is the general standard for these sorts of discussions.

Even comparing to industrial most operations don't use anywhere near as much electricity or water. The new gigawatt class datacenters are in the same ballpark as aluminum smelters, but rather than melting metal they sink all that energy into water.

Because we already do. Its why electricity costs money. In my area big consumers and producers already pay through the nose to tie into the grid.

What we _should_ be asking is where all the money we paid for infrastructure and upkeep went for the last two decades of decreasing power usage.

any reason you won't send #2 to a pcbfab? include assembly if that's an issue.

We can also time shift many of the things we do. Does your fridge need to run between 3-5pm in the heat of summer? or can it make sure its a little cooler to avoid running then? (trivial example, probably not a good one)

I'm sure there are better examples, but your fridge idea doesn't work. Fridges already operate on the edge of freezing, so if you make it a little cooler you will ruin all your food. Also 3-5pm is peak hangry time.

A modern fridge also uses approximately five watts, on average. There are far better targets.

good thing the grid cares about long term average real power and not instanaenous reactive power then.

Demand response for things like hotel air conditioning is a thing: https://www.bbc.co.uk/news/science-environment-23343211

Batteries are also getting cheaper and cheaper

This is why a major part of the solution is electric vehicles. Why put batteries in a warehouse and then run vehicles on petroleum when you can put batteries in a vehicle, install twice as many renewables because you now have more demand for electricity, and then charge the vehicles when generation is a large percentage of rated capacity and still have enough to run the rest of the grid when it's a smaller percentage?

And they are the only real solution. Demand fitting production is never going to work unless we give up all the autonomy.

It will be a mix. There is certainly still a lot which can be done on the demand side, e.g. when to cool a cool storage house during the day, or when to run certain production lines.
