Desktops and servers are hardly the entirety of the world. They don't even dominate it. Ever heard of ARM?

Yes, but I don't see any support for it, or any non-x86 architecture, in the DragonFly BSD source tree, so I don't think DragonFly BSD is that interested in embedded systems.

If Linus felt that way about 32-bit, there would be no Android, or it would have to develop its own kernel. Sheesh. FreeBSD and linux are found in routers and such with very weak CPUs.

So they've made different choices than DragonFly BSD.

Hey, now that the systemd nutters have broken Linux we can go back to calling Unix Unix instead of *nix.

At least one trademarked Unix uses a launch-on-demand-based init daemon, so it's not clear that the use of systemd-the-daemon is sufficient to make Linux not be a Un*x. Maybe systemd-the-software-bundle is sufficient.

What does Unix have to do with the Linux kernel? *nix is used for various "Unixes"

What's a "Unix"?

Is it a system based on AT&T code? If so, how much AT&T code has to still be in it.

Is it a system that passes the Single UNIX Specification test suite and whose supplier is thus allowed to license the "Unix" trademark?

Is it a system with a Unix-compatible API?

formerly also because of possible trademark issues. Linux is not one of them.

Linux is not one of the first types of OS in that list (if there are any bits of code AT&T made publicly available that are in Linux userlands, they're probably small enough not to count), and I know of no Linux distribution that's passed the SUS test suite (unless K-UX is a Linux distribution), so no Linux distribution I know of is one of the second types of OS in that list.

Linux is (or, rather, most Linux distribution are) most definitely one of the third types of OS, and people do speak of those OSes as "Un*xes", at least, even if "*nix" is used only for the first type of OS.

We also use hard drives for backups. We make sure we do weekly read tests on drives and that the data is actually valid. We also run a SMART check on each backup disk before it is used and replace and destroy the ones that fail. The only bad part about hard drive backups is secure high speed interfaces for off-site devices.

I can't verify the source, but this article suggests the machines will be Power8 based. Assuming these are the machines in question.

No, those machines are being built for the Department of Energy (DoE); NOAA, for whom the machines being discussed in this thread are being built, is part of the Department of Commerce.

I just created an account for myself. Apparently men can't see what the competition is like (males interested in women can't search for other males). I picked a few people (friends) who haven't used the site, and they aren't present. I don't see anything on the site that shows how old my account is, but it only has the very basic information that I just provided, so I'd say they hadn't previously auto-created my account from Facebook.

When I "created" mine just now, I did the lost password search using the same email address that I use with Facebook. Apparently they let you create an account that way, if you didn't have one already.

I did notice that they have a one-click account creation, so she could have clicked it in the past to log in, and forgot about it.

So much for a perfectly crappy conspiracy.

There are things called lathes and other machine tools that can reproduce themselves. Without that capability, the Industrial Revolution would have never happened. The real question is how many of these kind of tools together with a good smelter do you need before you can be self-sufficient and keep making your own sets of tools out of raw materials?

This is a big deal because it would be nice to get a set of these kind of tools into the hands of people in 3rd world countries, or for that matter have a few of them cached in a bunch of random places on the off chance that our current technological civilization will collapse completely. It is also something important to know about if you are planning on building a colony on Mars or the Moon, as such a set of tools that make tools can help such colonies grow much easier.

Since everybody who has sent astronauts into space and routinely sends spaceships into space has nukes (except for Japan.... and nobody doubts they have the capability of building nukes), the treaties involving the legal status of objects in space has some real enforcement teeth. The question that needs to be asked though is if any country would be willing to start a global thermonuclear war over a sovereign claim made by another country?

You forgot a few parts of that treaty:

Article VIII

A State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body. Ownership of objects launched into outer space, including objects landed or constructed on a celestial body, and of their component parts, is not affected by their presence in outer space or on a celestial body or by their return to the Earth. Such objects or component parts found beyond the limits of the State Party to the Treaty on whose registry they are carried shall be returned to that State Party, which shall, upon request, furnish identifying data prior to their return.

In other words, sovereign claims can still happen for stuff that is mined. You may not claim the whole Moon, but you can claim stuff you pull off of the Moon.

Another very important part of this treaty is this:

Article XVI

Any State Party to the Treaty may give notice of its withdrawal from the Treaty one year after its entry into force by written notification to the Depositary Governments. Such withdrawal shall take effect one year from the date of receipt of this notification.

In other words, it is a paper tiger that is ultimately meaningless against any real sovereign claims. I think this provision will ultimately be invoked by some country when they try to make a substantial move to make a sovereign claim by actually going to the Moon or Mars... whatever country that might be.

Slowing down a vehicle constructed in space down to Low Earth Orbit velocities (actually reducing potential energy but it does increase in actual speed) from a higher orbit is much easier than sending it up from the Earth. You also have options of using extremely high ISP engines like ion thrust that may not have very high thurst but can be used for months or even years continuously.

Manufacturing spacecraft from a factory in space would be much easier to accomplish.... assuming that the factory is built in the first place. An O'Neil habitat would be a good way to make that work if you needed a crew, although that is quite a bit of infrastructure you would need to put into place in order to get that factory built in the first place. Once such a factory is built though, it would blow away any Earth-based satellite factories in terms of marginal cost to build more satellites.
