U6 (currently at 7,7%) includes all of the following: "People marginally attached to the labor force are those who currently are neither working nor looking for work but indicate that they want and are available for a job and have looked for work sometime in the past 12 months. Discouraged workers, a subset of the marginally attached, have given a job-market related reason for not currently looking for work. People employed part time for economic reasons are those who want and are available for full-time work but have had to settle for a part-time schedule. Updated population controls are introduced annually with the release of January data." So, unless someone gives a comparison between the data and methods of the Bureau of Labor Statistics vs shadowstats.com, or at least explains exactly what shadow stats.com is counting, I'd tend to trust the BLS as giving better statistics. (Though I don't particularly trust the Trump administration on statistics, I also don't know that the BLS has been that corrupted quite yet)

I bought my first house (in the USA) in the early 1980s for a little over 3 times my annual income - putting more than 15% down to get a mortgage interest over 12%, and during a time inflation and unemployment both were at 7% to 10%. What I got for that was 1,000 sq ft plus an unfinished basement on a lot less than 1/10th of an acre, 3 bedrooms (though you had to cross the unheated part of the attic to get to the upstairs bedroom), 1 bath, no central air, no kitchen cabinets, a 1 car garage with a gravel floor that was too small for a minivan.

Comparing new houses built in the 70s to those built in the early 2000s: median size went from about 1700 sq ft to about 2300 sq ft; median number of rooms went from 5 to 7; central A/C went from 66% of houses to 89%; higher finishes and amenities were increased in number.

This. The Mercator projection has straight lines for constant compass headings. It's hardly the best projection for other uses. And unless you're going true north or south, a constant compass bearing is not the shortest route, anyway, except for east-west at the equator.

you know what "personal autonomy" means, right ? that means the ability for YOU to go ELSEWHERE regardless of what someone else provides.
so you can walk, bike or ride a scooter in your present neighbourhood but not travel across the country. youre not mobile and dont have personal autonomy if youre dictated to by the whims of mass transit run by a corporation.

By your meaning of "personal autonomy" driving a car does not give you personal autonomy because you rely on roads built by others and on vehicles made by corporations.

More likely, this is one of the steps that will help people to learn to grow bespoke human organs for transplant.

And little lambs eat ivy.

No problem. I spent 43 years designing HVAC and plumbing using the crazy US customary units, it can get pretty convoluted converting between all the different measures, and I've had problems with them sometimes. Besides these "calculations" are way too rough to be accurate.

I think your calculations may be off. (I know mine weren't very precise) Let's say you need an average of 1.5 Tons of cooling for the day. That's 24 hours at 18,000 btuh or 432,000 btu total. Your proposing 18F temperature rise, which is pretty high for a chilled water coil in an A/C system - traditionally they ran at 10F, though modern systems are often greater, I've designed systems up to 16F. Still, using an 18F dT would require 24,000 lbs of water, which is about 385 cu ft, or a cube 7.25 feet on a side, basically a small room. I see you're only accounting for 12 hours of cooling with the water, but if you did that, you would need to use an average load for those 12 hours close to the 3-Ton peak.
All the rest of the complications and expenses remain, making it impractical for a single family home even with a time-of-day rates break.

This could, in principle, be easily solved-- air conditioners could easily store coolness. Water has a high heat capacity, and you could cool water during the solar peak, and use it to cool your living area in the afternoon.

Water storage is very inefficient in terms of weight and volume. Ice storage is better, since the heat of fusion is much greater than the heat capacity for a reasonable temperature difference, so I've seen ice storage used in a few large projects. Still a typical house has maybe a 3-Ton A/C unit, which is the equivalent heat removal rate of melting 3 tons of ice per day. Since you don't typically need full cooling all day, say storage of 1.5 ton of ice overnight, melting it during the day to supplement 1.5 ton of dx A/C at peak (actual numbers will undoubtedly be different). A ton and a half of ice requires hefty support, takes up about 52 cu ft of space, the tank & equipment to freeze and melt it efficiently takes up space and has significant cost, and the refrigeration cycle is less efficient since the evaporator has to get down to well below freezing while air evaporator coils operate around 45F, you have a lot of extra water piping and coils, and you still need a 3-ton refrigeration system but with more piping and controls It's probably not cost effective even if you're paying time-of-day rates.

I believe it was the OG Socrates who first started bitching about the ignorance of youth.

Actual Socrates loved the youth (wink, wink).
In the end, Socrates was executed for corrupting youth - the allegations being that he taught the youth to be anti-religious and not properly respecting the state's gods.

Copyright originally came about as a response to the invention of the printing press, and the subsequent publishing (for sale) of books without compensation to the authors.

The "right" to copy, print, and sell particular books was originally granted by the government to the publishers, not the authors.

The real solution is a Supreme Court that cares about democracy.

You may be overestimating the number of successful recruits. I took a test for an ATC job application back in the late 70s. It included listening to increasingly long lists of words and numbers and writing them down after a short delay. I'm pretty sure I didn't do that well, but they kept my name on a list of possible hires for a year or so until they notified me that I would have to respond in order to keep my name on the list. I had gotten a different job in the meantime, so I declined. I don't think they were hiring very many controllers at the time, but if I had kept my name on the list I might have been hired when Reagan fired all the striking air traffic controllers. Anyway, that test would be pretty hard for most people.

. . . Excel uses some kind of BASIC variant that nothing else supports.

Actually, LibreOffice does a pretty good job handling Excel VBA macros.

Need to switch to pedestrian mode.

I had the opposite problem once. Wondered why the GPS kept saying "turn here" after I was already in the intersection. And then it tried to send me the wrong way down a 1-way street! Finally figured out it had somehow been switched to walking mode.
