Aha, OK.
Although most of that stuff is common sense (space is three dimensional, no sound in space, no friction in space, etc), a good portion of it is just someone's opinion on what is practical (the orientation a spaceship will fly, the size of a spaceship ("Space ships are not boats"), space ships don't have windows, etc). These things aren't impossible by any stretch of the imagination and are only "wrong" in as much as it was the author's opinion that it just wouldn't happen that way. He even proves that with some of his own comments. I can build a space ship any size and shape that I want, and fly it any direction I want. I can make the deck layout like a skyscraper (as he put it), or like the Enterprise. It doesn't matter.
At the end of the day, that article doesn't disprove anything, and doesn't tell me anything I didn't already know.
