TRON is rarely used outside of Japan because the specification documents are mostly in Japanese. TRON is more like an industry standard for an embedded RTOS than a concrete implementation. Of course, some open-source code is available, but these are reference implementations. More info:
Exactly. John C. Dvorak is a professional internet troll disguised as a tech journalist. He uses misinformed rants ( or "controversial opinions" if you like the euphemism better ) as a source of hits. He has trolled the FLOSS and Mac communities for years. But trolling the White House ?. That's effing crazy.
If you want real subversive fantasy, I recommend Andrzej Sapkowski's The Last Wish and the other of books from the saga. It has everything: The main character is a male witch (or witcher), the female wizards have formed a secret society to take over the world and nonhumans (elves,dwarfs) are subjected to human racism and bigotry.
