There seems to be this notion that capitalism and socialism are binary concepts, and that socialism and communism are the same. The truth is, they are on a spectrum, with capitalism and communism at the extremes. Somewhere along the spectrum is likely the optimum solution. Where productivity is high, and inequality is low. Everyone is too focused on the advantages and disadvantages of the extremes to explore the area in between.
Just because there are numbers in a computer doesn't mean that those numbers translate into material wealth. Remember Elizabeth Holmes? Her net worth went from $4 billion to zero in a blink of an eye. Was her wealth ever real in a material sense? Are any of those net worth numbers actually real?
A simple question with a very complex answer.
At the root of it, wealth is having something other people desire. Elizabeth Holmes supposedly had technology that many other people wanted. It turns out, she was lying. Therefore, the demand for her "product" disappeared.
People's desires change over time in an unpredictable fashion. That's why it's a good idea to diversify your wealth. You avoid getting burned by what's trendy.
Even the floppy drives of the day were so screwed up that they would randomly destroy disks because people misused them all the time.
I have little sympathy for the student.
That takes me back... When I was in college the closest computer lab with a printer to my dorm was general access. Anyone with a school ID could access it. I would finish up a paper, throw it on a floppy disk, and walk a block to the lab to print it out. Every floppy drive was broken! I talked to one of the students in charge of the lab. He told me people kept putting disks in backwards or upside-down.
After that, I started walking the extra two blocks to the engineering building. All of their floppy drives worked! Amazing what happens when you keep out the unwashed masses.
Part of the problem is the slogan "Black lives matter" is too short. People are left to fill in the rest of the slogan themselves. This leads to a variety of interpretations for Black Lives Matter...
...more than white lives
...more than police officer's lives
...as much as anyone else's.
The interpretation of the first two results in things like the "All Lives Matter" movement. The last interpretation is essentially the same as "All Lives Matter".
Yeah, I studied calculus, discrete math and linear algebra as an undergraduate, and I can't make heads or tails out of articles that I think I ought to be able to... I'd like to at least know which other book(s?) I should read in order to be able to understand the wikipedia articles.
Exactly! There's a gap in the knowledge. There are many rudimentary articles and then there are some articles that are incredibly complex, with nothing in between.
That's because Wikipedia isn't a manual. It's a knowledge compendium.
So in order to understand those math equations, maybe you would need to learn the simpler equations leading to them.
I'm fine with that. Just link to the simpler equations in the article so I know what they are!
I've read some pages concerning statistics that have math operations I've never seen before. I've done differential equations in the past. I know what a mean and standard deviation are. I'm familiar with many math concepts. This was completely foreign to me. There was little to no explanation as to what it was.
What are they even going to do with all of those MBA's? A large company has use for maybe two dozen. They are all management, so they aren't producing product. By definition they will be overhead, which is bad for the bottom line. In theory, the return on investment for MBA's is improved efficiency. However, the diminishing return curve is very steep.
Unless, Amazon is starting a business consulting division...
Is there really not a non-autmotive niche that you can find? I can;t beleive that all internal combustion engines in all fields will disappear at midnight on 1/1/2028.
I'm sure internal combustion engines will be around for decades. However, once the automotive applications dry up, so will the vast majority of jobs. Competition will be fierce. Project funding will be low.
The notion of suborbital/ballistic transport has been downright common for decades.
Yup! There have been lots of attempts X-30 X-43 X-51
This just takes a slightly different approach. Rather than making a "space plane" that breaths air and lands like a plane, it takes a spaceship and lands it like a helicopter.
The point stands though that this is incredibly wasteful
The idea is to eventually create the methane fuel via the Sabatier process which converts carbon dioxide and water into methane. This is a necessary capability to refuel on Mars. Using solar energy to power the fuel manufacturing process would essentially make this vehicle solar powered.
Most noxious emissions from combustion are due to:
A. Oxygen reacting with nitrogen from the atmosphere. Which isn't a problem since rockets don't use air, but instead carry their own oxidizer.
B. Incomplete combustion. Which can be mitigated with careful engine development.
Once out of the earth's atmosphere, aerodynamic drag goes away. Which also might save some energy.
Please watch the entire talk. It's very informative.
The closest it's been was 2010. It's been all downhill since. Gnome 3, Systemd, etc... Nobody has really been able to get the mojo back. Not even Cinnamon/Mint.
I feel it should be noted that they separated Thunderbird and Lightning into two separate entries in the survey. For those unaware, the calendar plugin for Thunderbird is Lightning. Therefore, they should be counted as one. Doing so would make them the winner hands down. Unfortunately, since the separated them, Gnome-Calendar was the winner.

Huh? The pressure difference, if they manage to make a perfect vacuum, is 1 atmosphere, about 15PSI. Pretty sure regular old steel can handle that. Natural gas in pumped through pipelines at about 250PSI, and a leak does not cause the entire pipeline to catastrophically fail.
Correct. A vacuum is not some crazy pressure differential. Perfect vacuums are difficult to achieve because it gets harder and harder to find those pesky air molecules as the air pressure drops. Not because pressure vessels can't handle it.
Go to the hardware store and look at the cheapest and most expensive vacuum cleaners they sell. Same plastic hose on both of them.
Where did you learn this? Air pressure travels at the speed of sound. A mass of air traveling at the speed of sound is rare. Air traveling at the speed of sound would experience a lot of friction from any static surface and slow down.
The US is near the top in countries that:
a) Have the biggest impact on our environment (both climate-related & otherwise), and
b) Have the resources to do something about it.
True. But what gets ignored is the fact the US does do something about it. Historically, the US has been a leader in environmental regulation. Previous efforts at international agreements (Kyoto) failed because they didn't recognize that.
I agree the US can do more, but be careful not to paint a picture that it is doing nothing.

What about Lavabit? I hear they are up and running again.

So I tend to look at what Musk promises, not when.
Musk puts new meaning to the idiom, "better late than never."
Sure, most of his projects are behind schedule, but many people regard them as impossible in the first place.

All of those MBA's are going to destroy the company with their "case studies" (i.e. anecdotes), buzzwords, and group-think.

I develop engines for a living. I've come to accept the fact I will have to find another career in ten years. Many of my coworkers have as well.

Ubuntu is Gnome territory, so I would fully expect to see a lot of Gnome-love in the results.
But there isn't. Most people are using Thunderbird. However, the people that ran the survey screwed up the results.
A link to the text slides was available, allowing for a quick peruse without having to watch the video, right here: https://www.slideshare.net/dus...
Aww, how corporate of them!

I would be most concerned with debris in the path of the vehicle. Air is compressible, a piece of steel, not as much.

So that PSI turns into quite a lot of force. I once tried to pull a vacuum on a stock-pot and it crushed on me. That was only 10'' diameter.
A stock pot is not a pressure vessel. Try it with a pressure cooker and report back.
Air fills the vacuum at the speed of sound.
