Heh, that's my daughter - mostly self-taught with just enough misdirection from me to keep her guessing. The essay was from 1995, but was just in a listserv. The webpage was done in the early 2000s.


My dad, John Perry, wrote this essay and followed it up with a book - The Art of Procrastination. I love to see the essay rediscovered & will share this thread with him.


From Groq using Llama 2 70b: To calculate the volume of space required to contain the world's population, we need to first convert the area calculated earlier to square feet.

Area (square feet) = 600 square miles × 5,280 square feet/square mile = 3,160,000,000 square feet

Next, we need to assume a height at which the population can comfortably stand. Let's assume an average height of 5 feet.

Volume = Area (square feet) × Height (feet) Volume = 3,160,000,000 square feet × 5 feet Volume = 15,800,000,000 cubic feet

Now, we need to convert the volume from cubic feet to cubic miles. There are 1,476,333,333 cubic feet in a cubic mile, so:

Volume (cubic miles) = Volume (cubic feet) ÷ 1,476,333,333 Volume (cubic miles) = 15,800,000,000 ÷ 1,476,333,333 Volume (cubic miles) = 10.7 cubic miles

Therefore, to contain the entire world population, we would need a volume of approximately 10.7 cubic miles, assuming an average height of 5 feet and a density similar to that of a solid object.

Please note that this calculation is purely theoretical and doesn't take into account factors like personal space, comfort, and actual population density.


Please don't just paste AI-generated summaries into a low-effort comment. I don't know why your summary only picked up on the first half of the first paragraph, but estimating global population volume has nothing to do with the article.

Also, even taking the assumptions at face value, your model's calculations are wrong by several orders of magnitude. There are not 5,280 square feet in one square mile and 600*5280 is not 3,160,000,000.


If you weren't concerned with preserving life, you could take the current population of Earth, multiply by the average weight of a human (69kg according to Wolfram Alpha's sources), assume that we have the same density as water, and find that we could all fit in a 0.5km³ box.


If it is a USB iPad, you can plug it into an external display. USB-C to USB-C monitor, or get a USB-C to HDMI or DVI adapter. You can also use a USB or Bluetooth mouse if the digitizer is broken.


Whoa. Does it automatically turn on? Note that I can’t get past the lock screen. Otherwise that’s a wonderful idea and I might try it anyway. Thanks!


Plug it into a USB-C dock and plug a USB mouse in. You can tap the lock screen code in that way, or you can type with a USB keyboard.

Note: iPads only support USB-C displays that operate in "DisplayPort over USBC" mode, not "HDMI over USBC" mode (which requires more active circuitry), so only some USBC monitors will work. If you're worried, I suggest grabbing a DisplayPort-to-USBC dongle and plug it into the iPad that way.

Brilliant, thank you so much.

And thank you HN. You’ve helped salvage an artist’s work. Hopefully procreate will back up their art to iCloud one day.


One of the features discussed in the keynote for this new app's announcement is that they are adding iCloud syncing as an option, and that all relevant new features coming to Procreate Dreams will also be added to Procreate. To me that sounds like there's a good chance they'll add iCloud sync to Procreate soon!


Volume is more like a tenth of that, I think? Maybe interior dimensions 2 meters diameter and 5 meters length gives around 16 cubic meters if my math is sane (Religion major, so go easy on me if not).


I love these stations. SomaFM carries this and others (or maybe they are just similar mash-ups). I have tinnitus 100% of the time, and silence is the enemy. This kind of sound - indistinct, with variety and high frequencies, is the most helpful.


Faster way to disable FaceTime is to hold power and volume-up for a few seconds to bring up the power-down interface. You don't need to power down or do anything - once that interface loads, the iPhone will disable FaceTime login.


Can can doing that be faster?

Pressing the home button five times can be done in under a second.


a^2 (9) + b^2 (16) = c^2 (25)


And you are qualified to express this view how?

Experts are usually vetted by regulators and other experts, not random members of the public. As anyone is presently free to say whatever they please, I see no reason to share my personal information with the world.


Do you remember when Hank Paulson said he had the utmost confidence in the stability and resiliency of our markets?

Right before a literally historic housing market crash occurred, that then became an enormous stock market crash.

How much more of an expert would you want than Hank Paulson, who added billions of value to Goldman Sachs bottom line, who he himself made $1bn working there, and who had been in the financial industry for 30+ years at the time, and who was the Secretary of the Treasury?

What kind of "expertise" should he have had in your perfect utopia?

I should remind you that Paulson was indeed vetted by regulators, other experts, and Congress, and was widely considered a great choice as SecTres.

We see how that worked out.

An autistic medical doctor predicted the housing market crash 3 years before Paulson made that statement, so as far as I can see, so much for your so-called experts. In fact, I think if you'll try less to defer to experts and more to defer to history, you'll find a very long list of people who were held in the highest esteem who continually got shit wrong, and very very few who got it right.


Like the experts who said the virus wasn’t a problem and also that masks are useless?


> Like the experts who said the virus wasn’t a problem and also that masks are useless?

This being a wonderful example of the right-wing propaganda so prominent (though I won't say universal) in this mess. Cause a problem, then blame others for it.

We've all had more than enough of correcting it at every turn. Why not do something about that?


Nassim Nicholas Taleb has a lot of material on so-called experts vetted by other experts whose accuracy is no better than a chimp throwing darts.


That would be politically inconvenient.


It is unfortunately true that intermittent sources of power generation subtract from grid stability. Texas (ERCOT region) had a huge incident back in 2019 with rates skyrocketing to $9/KWh for over 90 minutes. Many attributed this to an over-reliance on wind generation.


No, that would be using solar as a scapegoat for bad planning.


What do you mean by bad planning. Are you talking about planning that is flexible and responsive to pick up the slack. For example, a high demand day that is cloudy and not windy?


I am talking about designing a grid to be robust, and has enough spare capacity to handle difficulties without failing catastrophically.

For critical infrastructure, you design for worst-case scenarios, inflate the safety margins, and make backup plans (like a plan to gracefully degrade service).

Failing this and cutting corners is what I would call bad planning.
