Is there a way to examine the status of a specific port from the Windows command line? I know I can use netstat to examine all ports but netstat is slow and looking at a specific port probably isn't.
Other symbols I have seen used for "is defined to be equal to" are three horizontal lines instead of two, and $=$ with either a triangle or "def" written directly above it. I have seen variants of these used by people who predate widespread knowledge of computer programming. It would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen). An ...
I learned that $\models$ stands for semantic entailment, while $\vdash$ stands for provability in a certain proof system. More concretely: Given a set of formulas $\Gamma$ and a formula $\varphi$ in some logic (e.g., first-order logic), $\Gamma \models \varphi$ means that every model of $\Gamma$ is also a model of $\varphi$. On the other hand, fix a proof system (e.g., sequent calculus) for ...
In summary: The interplay of meaning and axiomatic machine mathematics, captured by the difference between $\models$ and $\vdash$, is a subtle and interesting thing.
What is the meaning of the $c$ in $C_c^ {\infty} (\mathbb {R})$?
