I agree, although CRS-7 was higher altitude so the atmospheric pressure and aerodynamic forces were smaller, so that may not be unexpected.

The abort is the redundancy... ;-) I'm not sure what specifically you are thinking about, but in general since an abort is already one critical fault away from the nominal case, I believe the requirements for redundancy are lower.

To be clear, propulsively landing after an abort was never planned -- you've already used up the fuel doing the abort. Plus, depending on when you abort, you could be half-way across the Atlantic.

Well, even if everyone doesn't want to run their own back end, if it's at least possible to do so the chance of someone offering to run that service for a small fee is infinitely greater than if not.

I just bought an OpenEVSE electric car charger and this is what it does. They run a service for it, but if you prefer you can change the url and run the service yourself.

It doesn't have to be "smart" or internet-connected to be remotely operable.

Their point presumably was that once the kids don't breastfeed exclusively, the mother doesn't need to stay home to perform that task.

Given that daycare effectively pools more than one family's children per adult caretaker, it should still only cost a fraction of an equally good job's salary.

I thought the article would be about certifying software, not software developers. That would have been a more interesting topic to me... ;-)

Not during the night. When the satellite is out of direct sunlight, it also does not see any illuminated part of the Earth.

This is extremely unlikely, and if it were to happen it is for an extremely small time. I have never heard of this being a practical concern.

A simple median filter will take care of it. Have you seen what an unprocessed image from the Hubble Space Telescope looks like? It's riddled with cosmic ray tracks, and they all get filtered out.

Not only that, but it first has to actually pass in front of the star. This gets increasingly likely as you look at fainter and fainter stars, but the sky is still mostly empty and is not as common as you might think. (Olber's parado

This is totally false, the solid angle subtended by the satellites is tiny so the effect of their obscuration is totally negligible.

First, satellites are only visible in the optical when they are illuminated by the Sun, which is only for a fairly short window after sunset and before sunrise. The exact size of the window depends on how high they are, but most of the good

Isn't that solvable by not requiring 2fa for "registered" devices?

An internal combustion engine runs on an Otto (or maybe Atkinson) cycle, though, not a Carnot cycle. All thermodynamic cycles are heat engines, but their efficiencies aren't the same. How do you mean a Carnot cycle isn't reversibl

Ok, that's fair.

That's not "disobeying a teacher", though.

This is how it works in Sweden, at least for people with reasonably simple situations: You get a piece of paper saying "this is what we think you made and how much taxes you should pay". Unless some reporting is wrong, you just lo

I'm sorry you feel that way. I was apprehensive about having kids, and it's certainly true that it's been a big change to my life where I now can't do a lot of the things I used to enjoy doing. However, I find that I&#x2

Why do you think your kids will have to toil more than you? Achieving financial independence is more about prioritizing your wants than having a huge income, and that's definitely something you can pass on to your children. I think i

Raising children is an instinct that's hardwired in each of us. Maybe, but raising children well certainly isn't...

In fact, we don't (at least the first $5k, if you have access to a DCRA through your employer.) Why you need to have access to a DCRA and can't simply deduct child care expenses, I have no idea. It's like with an FSA, it seem

I understood it as it would "pay for itself" in increased tax revenue in the future as the children who had access to better child care become more productive citizens. That sounds like how any other investment works, you pay no

They are using 301 stainless which, as far as I know, cannot be hardened.

EVs are less efficient at highway speeds Huh? Less efficient than what? There is no way it is less efficient than an ICE.

A good teacher doesn't let you redo the same simple math problems. Mine didn't.

Your assumption here is in exact opposition to the article. Unless you can successfully argue that the numbers in the article are wrong, it appears that what seems like a preferable situation is, in fact, not.

The think that makes this scaling "bad" is that moment of inertia is going down faster than everything else and this means the required control frequency goes up. A Falcon-sized rocket may only need to correct its course 50 times
