The development machines used to create satellite software are likely running Windows, but the satellites are more likely to be running a real time OS such as VxWorks, Rodos, RTEMS, etc.
How does it pass safety regulations without an integral part of the vehicle? How do they publish performance data if it can't move on itself?
Not that those are insurmountable obstacles, but a law that says "You can't claim your vehicle does 200 miles on a charge if it doesn't include a battery" or "You can't claim your vehicle is safe in a frontal crash because the battery absorbs some of the energy except you're not including the battery" don't seem unreasonable.
There is no specific regulation, other than selling incomplete products as completed products.
For example, its perfectly legal to advertise a car as saying its a car without engine. You just cannot advertise it in such a way that the viewer thinks he can buy the car and just enjoy it.
How's this any different than the situation with PC parts? You have CPU and GPU manufacturers advertising their products with images of games being played, yet you need to buy half a dozen other parts before you can start gaming.
Assuming that 50-60% of the population of cities is working is probably too high. As a simple example, the third table at https://www.health.ny.gov/statistics/vital_statistics/2016/t... data for New York City for 2016. Total population is 8,537,673. Population under 18 is 1,798,888. Population over 64 is 1,155,075. That's 35% of the population right there.
Some of them might be working, of course. For the kids, this is not likely to be more than 10% (which would be _all_ the 16 and 17 year olds, pretty much). For the seniors, let's guess 33% (pretty much everyone under 70). That leaves 28% of the population in the kid-or-senior age range and not-working and 7% in the kid-or-senior age range and working.
To get to 50% overall working with those assumptions, you need 43% of the population to be prime age and working. The prime age population is 65% of the total. So you need 43/65 = 66% of the 18-65 age population working. But in 2017 (yes, I know, a year later; I haven't found the 2016 equivalent) https://www.osc.state.ny.us/reports/economic/labor-force-tre... claims a labor force participation rate of just about 60% for NYC (see page numbered 14 in the document, page 17 of the PDF). And that's the rate for 25-64, which should be higher than the 18-64 rate, because as the document notes "people between the ages of 16 and 24 are more likely to be in high school or college".
Page 15 of the document (page 18 of the PDF) does show labor force participation rates for 16-24 and 65+ in New York State and our "33%" above for seniors was likely a significant overestimate based on that, though it's hard to tell: NYC labor force participation may not match the overall state very well, obviously.
Anyway, under the (imo optimistic) assumptions above, something like 45% of the overall population of NYC is in the labor force. Or in other words if you ignore the 18% of the population that is children under 15, it's about 55%. So your estimate was pretty close if you ignore the existence of kids...
Or put another way, if the prime-age labor force participation rate is 60%, there's no way that 60% of the overall population is working. Just not possible.
I appreciate your statistics but I'm not quite sure how they are related to our discussion.
Most of the kids in NY state are living under the care and support of their parents and aren't working, therefore they shouldn't even be a factor in population/labor force participation metric.
Additionally, many of the old people who aren't working shouldn't be factored in either because they are receiving quite high pensions to live from, as well as social security.
When you factor this in, my initial ratios still stand. Out of the 325m people living in the USA, 45% are working (145m). When subtracting the 30% of Americans who are retired or under the care of parents, you are removing 100m people.
Therefore, as you say, the "prime age" labor force participation rate is 65% (145m/225m).
Applying this ratio to my original numbers, 45.5 million people are laborers in the Northeast. The other 25m either used to be laborers or are protected financially by laborers.
We cannot possibly say that an area like Amarillo TX, with just 100,000 laborers, is indicative of some nationally sustainable trend where cost of living is cheap and wages are still high.
This denies the existence of an extremely large block of humans, who are struggling despite earning decent money.
The original context, as far as I can tell, was "what fraction of workers live in the high-cost metro areas?", right?
We're trying to estimate this in all sorts of indirect ways, when the real questions, which I am sure we should be able to find answers for, are:
1) How many workers are there total?
2) How many workers are there in high-cost metro areas?
What we can't easily do is derive the answer for #2 from the total population of said metro areas; it's heavily dependent on the age structure of said metro areas and the specific workforce participation rates for those areas by age.
> Therefore, as you say, the "prime age" labor force participation rate is 65%
On average across the US, plausible.
> Applying this ratio to my original numbers, 45.5 million people are laborers in the Northeast
Yes, but even in the northeast not everything is in an expensive metro area, fwiw.
> We cannot possibly say that an area like Amarillo TX, with just 100,000 laborers, is indicative of some nationally sustainable trend
On its own, sure. But there are a lot more areas like that (by count; how the population totals look is not obvious to me) than there are big expensive metro areas.
That is, you might be right in your original claim that "half the country" are in the high-cost situation, but your data is not showing that very conclusively.
That said, I would be shocked if less than 1/4 of the country is in that situation. And yes, we should be aware that these tens of millions of people exist and of their situation.
Thank you so much for your well-reasoned response :) I think we've found middle-ground in trying to estimate these numbers too.
It sounds like we could ball-park the number at 33% of Americans being in high cost of living areas.
Additionally, it sounds like we agree that that percentage might change based on if you're looking at urban, suburban, or rural areas, and if you are factoring in dependents or retirees.
I think the question we ask from here is, "how do we increase the number of people who are able to have a large chunk of discretionary income coming in?"
For this the answer is probably political, contentious, and complex. Not everyone can be a programmer, as there's only 4 million computer professionals in the US right now. Not everyone can be a licensed employee either, who tend to make more money (health care, law), because labor supply is strictly regulated for these professions.
I think if we were to somehow reduce rent-seeking behavior in the economy (real estate and health insurance prices are pretty good indicators of state-enforced supply restrictions), then prices and salaries would begin to approach the mean again, which is around 50k per person.
I guess what I'm saying here is I think the roofer who makes 37k a year in Newark NJ is being underpaid, and the physician's assistant who makes 100k a year in Scottsdale AZ is being overpaid. I would wager their labor is of equal value, but is being artificially disrupted.
Years ago you could simply tape the prepaid business envelope to a 2”x4” block of wood, a brick, or anything else heavy and the mailman would take it. Too much fun...
Yeah, postage on reply envelopes used to be unlimited in the US. In grad school, there were lots of lead bricks around. So we did that once or twice, for laughs. But you know, the lead was actually worth something. But not as much as the postage.
This is a naive response I see given to iPhone users when they ask about how to get a certain feature. It’s obvious no research was put into this answer as a sibling comment to yours clearly helped out by suggesting Charles proxy which is now available natively on iOS.
NetGuard is a firewall which allows to allow/block traffic.
Charles proxy only allows you to see which connections are being made. They cannot be blocked, there is no firewall functionality. There is not a single app on the App Store that can behave like a firewall on an iOS device, and Apple would definitely not allow this.
So i personally think he has a point; Apple dictating what you may or may not do with your device, without giving you the possibility to opt-out, is not good.
Apples "walled garden" has positive side effects of course, like for example hardly any malware on iOS devices versus a lot of malware/viruses on Android devices.
But still, there should be the ability to opt-out of this when accepting the risks. Without this ability it's much like a dictatorship...
