In the beginning, Linux was free. I remember using it in college and learning about it and getting excited. If these big corporate players want traction against AWS and the like, they should be giving out free hosting to college students so they can tinker with it too.

And so they are. Look at Red Hat's Openshift.

False. It's a nice myth of antiquity, of the good old days being better than today but it is totally false.

Today's concrete is far better than what was produced in the past. Of course, I'm not talking about crappy badly done concrete but the good stuff that is used in most good engineering works. Sure, you can point to a government bid sidewalk falling apart but that is meaningless anecdotal evidence in this discussion. That's politics and greed, not materials science and chemistry.

The most common blend of modern concrete, known as Portland cement, a formulation in use for nearly 200 years, can’t come close to matching that track record, says Marie Jackson, a research engineer at the University of California at Berkeley who was part of the Roman concrete research team. “The maritime environment, in particular, is not good for Portland concrete. In seawater, it has a service life of less than 50 years. After that, it begins to erode,” Jackson says. The researchers now know why ancient Roman concrete is so superior.[...]the findings, which were published earlier this month in the Journal of the American Ceramic Society and American Mineralogist, are considered so important[...]

The concrete used by the Romans was apparently much better that the ones we use today. Since the Roman formula has been rediscovered, does that mean that todays diverse republics will be replaced by the Empire, and if so which Empire? Russian? Hegemon? Sith?
