Do you have a CNAME record pointing to a herokudns.com domain? Replace it with an A record that points to the IP instead. You can find the IP by going to https://securitytrails.com/domain/<something-1234.herokudns....

Even if this were the case, I would have needed $220K.

Or now.

To get these returns, BTC would have to appreciate 100x in value and you would still need those 200k$. While it has done this before, past returns are no guarantee of future returns. If you want to finance the 200k$ with debts... well... the percentage can kill you, or require you to or in a sizable chunk of income to pay it off. (Mortgages in some cheaper places in US are this size. )

I think you have that backwards? Taking off from Mars is significantly easier than earth because of lower gravity and a less-dense atmosphere.

How do you fuel the rocket on Mars?

All you need is oxygen and hydrogen. Both of those are actually plentiful on Mars.

And the machinery to gather them etcetera etcetera... Just because the raw material is there doesn't rocket fuel make. And I'd be hard pressed to say that oxygen is plentiful on Mars. There is some oxygen.

"And the machinery to gather them"

That machinery can be sent gradually and ahead-of-time.

"Just because the raw material is there doesn't rocket fuel make"

No, but it means that such fuel is at least possible.

"I'd be hard pressed to say that oxygen is plentiful on Mars"

The current understanding is that there's millions of cubic meters of water ice on or near the Martian surface (with even more suspected further beneath the surface). Sounds pretty plentiful to me.

Neither of those are plentiful on Mars.

Mars has lots of water ice, which is made (almost) exclusively of - you guessed it - hydrogen and oxygen.

So yes, both of those things are plentiful on Mars. Maybe not to Earth standards (or the standards of, say, Ceres or Enceladus), but certainly abundant compared to our own moon (at least as far as current information tells us).

It's all relative. If you already have enough energy to crack water, fueling a rocket is not a worry.

Thanks for the feedback! I don't have anything in the works right now, but will definitely consider it.

I have fond memories of learning VB3 from Teach Yourself Visual Basic in 21 Days, which had to be 500+ pages. It turns out it's tough to have a good introduction to a topic without going really long.

Very good points, thanks. I struggled with this myself as I was trying to plan out the structure of the book. I ultimately went with the "path of least resistance" (ASP.NET Core MVC ships with Bootstrap, jQuery, etc) but I agree that it could be better in future versions. :)
