You could argue that one difference is that Visual Studio is available to anyone prepared to pay for it.
You may be right, as the poster does not give any details. However, if we are to believe the poster, the build scripts, which in the case of VS would be the project files, are not given, and this _is_ a violation of the GPL.
Simple, don't use code that is covered by the GPL in your product. It's exactly the same as any other copyright license
While I agree fully with the comment, I want to emphasize that the GPL license is a model copyright license, because it _lets_ the user really decide. If the user don't want to accept it, then they don't use the software and that's it. Nothing else to do.
On the other hand if you purchase a computer with Windows preinstalled, and _after_ that you purchased it you read the license, and don't agree, then what? Will you get your money back? We all know that this is seldom the case. It is also a lot of trouble for the obvious.
FYI, for the last 10 years or so, I have repeatedly asked my supplier, who is a friend of mine, to buy a laptop without windows. He always replied: not a chance, though he used more colorful words (on the other hand I have bought custom built desktops with SuSE).
Constellation didn't get us any closer to the above objectives than we are with the Space Shuttle, or Saturn V -- not a step forward in any sense
I tend to agree that Obama got that right. But this does not mean that human space exploration and colonization needs radical new propulsion systems that will always be 30 years from now. We can do this with existing technology. As for the specific impulse needed I refer you to the book of Zubrin, where he has a lengthy description and discussion of the various engines/fuel, including nuclear thermal rockets.
Colonization usually means running from religious or philosophical persecution.
Any kind of persecution.
Zubrin, in the Case for Mars, claims that democracy and advancement (technological, society) happens when there is expansion; when there is possibility to go somewhere else if things get bad. It is an interesting read and I recommend it.
For example, as it has been said often in slashdot, linked lists are patented. With America pressing the world for ridiculous intellectual rights, extended to infinity, where will you go to escape this?
Necessity is the mother of invention, and the invention of a Mars habitat, IMO, will certainly give new ideas on earth (there is no way to destroy Mars habitat; you can't destroy it if it does not exist).
What makes anyone think that subsequent out-migration to habitable planets will work, when we can't get this one right?
It is my belief that it is the other way round. It is when we learn to cope with another planet (Mars?) that we will bring the knowledge back to cope with earth.
If Europeans hadn't colonized America, until they solved their problems here (in Europe), we would still be in the dark ages.
Colonization of other worlds is clearly impossible without manned flight.
Colonization of other worlds (which ones did you have in mind, by the way?) is clearly impossible without technologies that don't exist on Earth right now and won't exist for at least another few decades. Spending many billions of dollars on chemical rockets isn't going to get the job done.
Wrong. Look up "The case for mars" by Zubrin.
Get the followup volumes too:
Noise cancelling algorithm design using sh. ( Shhhhhh... )
Real-time traffic control with bash.
Time-domain-reflectometry made easy, with sed.
GPS satellite tracking with tr.
Build a species database with Python.
The funny thing about this list is that the last sentence is not funny; it's true.
Microsoft used it once to track down a virus writer. You may remember that case. But what it boils down to is that Office "called home" and reported to Microsoft what this person's GUID was. And Microsoft looked it up in their database to find the person who originally authored a Word macro virus.
This is false - though typical Slashdotist - anti-Microsoft hysteria.
Please slashdot moderators. Enlighten me why is the parent informative, but not the grandparent?
