I try connecting to localhost:3000 on various browsers and they all cannot establish a connection to the server. I also tried rails server -p 3001 and connect to localhost:3001, which failed as well. However, I tried 0.0.0.0:3000 , 127.0.0.1:3000, both of them worked and rendered the default welcome for rails. Then I tried localhost:80, which successfully told me "It Works" and I can actually ...
Generally, people use can't in speech and informal writing, and cannot or can not in formal writing or very formal speech. Also (as @Kris points out in a comment), cannot might be used when you need to carefully distinguish it from can't in speech.

The phrase "can not" may mean "cannot" or "can't," but it also may mean "able not to," which is much different than "not able to" as it conveys the ability to not do something rather than the inability to do it.
Why is “cannot” spelled as one word whereas other similar constructions such as “do not,” “will not,” “shall not,” “may not” and “must not” are spelled as two words (unless they are contracted as “...

So here it’s about minimizing ambiguity: can not permits two interpretations, while cannot permits only one. Such care is critical in the language of mathematics. As another example, West would tell you that in mathematical discourse, both “x is a minimum” and “x is a minimal” are valid utterances, but they mean different things.
So, "cannot" means something (denoted S) is impossible, while "can not" means the inverse of that something (denoted !S) is possible. These two statements do not imply each other. Of course, the second statement could be rendered much more clearly as "The variable can be not initialized," by moving the "not" next to the word being negated.
-1 Saying that something "cannot be overstated" is exaggeration and clearly never true, because anything can be overstated. (You just keep repeating that thing to the exclusion of everything else: now it is overstated.) So is using this phrase sloppy writing, or is it a well-understood phase that no longer means what it appears to mean?

Cannot is the only negative form that contains not rather than -n't. Theoretically, since it is a single word, you can say why cannot you... without a problem. My theory is that modern English speakers don't want to put cannot before the subject because it contains not and sounds like can not.

What do you call a person who cannot learn to use computers?
The irony of the idiom is that one would expect to be able to eat the cake that he or she owned. In that case, possession of the cake would logically come before usage of the cake: You cannot have your cake and eat it, too. Some other interesting observations: Paul Brians, Professor of English at Washington State University, points out that perhaps a more logical or easier to understand ...
You cannot "eat your cake and have it" or "have your cake and eat it"?

I cannot make sense of this quote by Virginia Woolf in "The Waves"
If you’ve worked in sales, you’ve heard it a million times: “Can you give me a discount?” Everybody wants a deal. And in a competitive marketplace, you’re probably tempted to give them one. If you don ...
