There was no economic benefit to the first colonies in America. Some time later they found a turkey and that all changed. It's appears we've found another one.
The entire shuttle program since day one was a political can of worms. The original premise was to have a cheaper option than the Saturn V, for purely political reasons. Then the vultures came in to divide the project up for political pork. In desperation NASA reached out for defence money and found the price for that (due to needing to get into polar orbits) was to change to an insane design where the launcher was strapped on the side of an enormous rocket instead of on top. It's a wonder it launched at all without flipping sideways and piling into the ground at Orlando. The infamous o-rings were so that bits could be trucked in from different states to share out the pork instead of large parts and shipping then in by barge like NASA wanted to do (and did with the Saturn V). I think the above poster is correct and that politics would have prevented repainting the tank.
In a lot of cases I'm probably telling people what they already know, but it's bound to be new to some people.
I refer you to Biosphere2. AFAIK there has been very little progress since then towards a truly closed ecosystem.
You refer to a stunt. NASA has been quietly working on things one little problem at a time so there has been progress. One little inexpensive project that has been fruitful was in Antarctica, growing tomatoes in simulated regolith during the polar night. Artificial soil that could be based on moon rock and artificial light.
Life extension? That depends on where the extension comes from
The method a few SF writers are playing with that seems to require the minimum number of impossible things before breakfast is to "upload" a copy of someone's personality/soul/whatever-the-hell-we-are and that copy becomes relatively immortal given shifts in hardware. Assuming the hardware to run the copy doesn't weigh much and is radiation hardened that creates possibilities for long range space travel where people are going to get zapped by very nasty radiation (a cost of travelling at relativistic speeds) and it's still going to take forever to get anywhere. Of course if we can actually get a copy of someone to work on a machine we'll probably be able to do something approaching an artificial intelligence by then and just send that out.
So a bit less power than the engines of a Boeing 747 supplied on takeoff from 1970 onwards? Also nukes are heavy, hence solar panels all over the place since the dawn of the space age and not a lot of nukes (nukes mostly in spy satellites that need to brush against atmosphere from time to time with their highly elliptical orbits). It may be trendy to attack solar for political reasons but in Earth orbit it's perfect for the niche. Point 5 - why open yourself up for ridicule?
exploration is a matter of packing up the food and drinks and heading out
FFS! Did an astronaut kick your puppy or something?
While "Commercial Space" sounds cool and all to promote new players like Musk it's worth remembering things such as it being Grumman who built the lunar lander and not NASA. It has been "Commercial Space" outside of Russia for a bit over fifty years. It's also worth remembering that currently Musk's "Commercial Space" hype has been about getting paid for government work and not commercial satellites like many others are launching. Not very commercial is it? The old players who are launching communications satellites are a lot more commercial.
I'm not knocking Musk, just a ridiculous misconception and silly free market flagwaving that got badly lost.
Good point. Personally I think things like the Diebold voting machines (designed by a convicted fraudster!) fail on many levels. I'm a big fan of very simple paper ballots and big high speed scanners to collate everything. When something is contested (which seems to happen someplace in just about every election anywhere) paper ballots allow a fallback all the way to manual verification if necessary.
What is referred to today as "Linux" is an operating system that has a lot more components than just a kernel.
Yes, yes, and the "computer" is the thing that sits on your desk that displays stuff while the "hard drive" is the beige box on the floor.
Don't mistake a technical term for lazy incorrect usage by people who do not know what they are talking about.
"Linux" is the kernel. "RedHat Linux" is a distro that uses the linux kernel. Lazy people call the entire stack linux. Android is a very different approach that also uses the linux kernel.
there are certain kernel features required by systemd
However you do not need SystemD to run those kernels which seems to be what you and the other poster are implying. SystemD is Lennart's special little empire building project and separate to the kernel.
The kernel is linux. Gnome desktop, redhat distro etc etc are all their own thing. Just because people are lazy and frequently call the entire stack linux doesn't mean that someone who isn't lazy is wrong when they are talking about the linux kernel specifically.
So yes, android is dominating not redhat, debian or whatever, but the article is about the kernel underneath.
File it with people making noise about Mac versus MS Windows when the topic is really about an x86_64 CPU.
The linux kernel is linux. Gnu/linux was the second attempt by Richard Stallman to raise awareness of GNU on the coat-tails of linux after people didn't take his first suggestion of LiGnuX seriously. Linux is not a GNU project. Their OS is called HURD. So your "fact" does not appear to actually be one despite it coming out of a book.
Indeed, that could be a problem, but the failure to teach computer science graduates mathematics to the level of high school probability and statistics is a far greater problem in my opinion. It results in posts like the above.
In that special case saving on weight is optimal cost efficiency. I doubt that any of the rover components cost as much as their percentage of the total weight divided by the cost to get the rover on Mars.
Why didn't that voting machine have ECC memory? Why didn't the software have bounds checking? Yes, I know it's common, I use some software (from a very large company that was run by a guy you don't go hunting with) that when it hits a some input data with a negative integer IT ATTEMPTS TO ALLOCATE NEGATIVE MEMORY, and of course, crashes - but things that stupid should never happen (especially since it's supposed to deal with very noisy data). If it's out of range for a bit of code to work on then don't let it in! Don't just check in one place and hope that catches everything, check everywhere that out of bounds data is a problem.
Personally I think when MS add virtual desktops and change their UI back to a MS Windows7 style it will be ready for the desktop. As it is MS on the desktop just gets too cluttered. Apple have done it so MS will surely follow.
SystemD is in userspace. There are no dependencies for SystemD in the kernel. Now I hate SystemD far more than most due to it causing actual failures for me in production, but spreading disinformation about it is dishonest.
Same with nvidia's own driver. Every time I've seen a machine where it looked like the nvidia driver was doing something wrong it's been a dead or dying fan on the card. The nouveau driver is great for what it does, but if someone is going to be using google earth you need the one from nvidia. Both are rock solid for what they do IMHO (and the fans on video cards are frequently shit).
No that's a real GPU so no luck there. In this case things like the "new" gnome (nearly ten years and still slow) which relies on a GPU may come up to the speed of the old one on hardware that isn't a 1337 gamer box.
The situation in the US in the 1930s was pushing in the way, but no, neither then nor today is it anything like the scale of Mussolini's ideas and practices (which was well and truly the full blown model - don't go easy on him just because he killed a lot less people than Hitler). Umberto Eco wrote a good piece on how to recognise fascism that gets linked to a lot. Trump is such a loose cannon that people are speculating we'll see a bit of the real thing soon, but that would be a pretty rough lesson to show you the difference. Hopefully it won't happen and you'll just be able to read about the misfortunes of others to see the difference.
We currently have processes that have shortcuts for cronies and those who flash some cash. While nowhere near ideal that's very different to a system where all but the cronies are locked out.
It's getting pretty difficult to think that there aren't a lot of people here who do hate America
Some of the press is focused on that and blowing it out of proportion. Remember that even Bin Laden hated some people supported by US government military aid far more than he hated the USA.

A free download is "nearly impossible"?

One of the roles of postgrads is often to give feedback on course material before is it put into practice.
Apparently you never programmed with the MFC or used win32 with com/dcom :-)
Using Win32 with com/dom is certainly a good idea, I wouldn't want something to mess up my pipes.
Thank you, I did miss it.
