comment How prove this polynomial inequality from a book
Here is Google Books link to the reference given by Lucia. I would be quite curious to know the name of the book where you saw this problem.

comment Hausdorff spaces with trivial automorphism group
There is also a series of papers by Kannan and Rajagopalan on the topic of rigid spaces. You can find there some further constructions and references. They also study strongly rigid spaces, which you mention in another question.

comment Stone-Cech compatification and ultrafilter
You can also have a look at these notes of mine which include proofs of some facts about ultrafiter construction of $\beta\mathbb N$. I would say the proofs there are quite detailed.

comment Stone-Cech compatification and ultrafilter
If you can be more specific, perhaps you could make a suitable question for math.SE from this. Asking not so specific question seems to be more suitable for chat. Over there at math.SE we have General Topology chatroom which is rather inactive these days. However, you need at least 20 reputation points to talk in chat. I am not sure whether you need 20 points on math.SE or 20 points on any site would suffice.

comment “a shape that … lies halfway between a square and a circle”
Since my suggested edit was rejected, I'll just point out in a comment that it is preferred to embed images using the editor/imgur instead of using external links to prevent link rot (as discussed on meta).

comment “The” random tree
I have checked internet archive to see whether the pictures can be recovered from there. But I was not able to find a snapshot with working images.

reposted images using the editor's interface - this might prevent link-rot, see http://meta.mathoverflow.net/questions/1012/inline-images-not-displaying-correctly and http://meta.math.stackexchange.com/questions/4205/permanent-picture-uploads
