What is a Front Porch used for?  What is a Back Porch used for?  What does it mean by active video?
I've been looking around on the internet and I can't find anything in depth on how the cable/connection functions. I've only been able to find simple pin out descriptions.  If someone can link me or point me in the right direction, I would be very grateful.
I already derived a QM expectation value for ordinary momentum which is: $$ \langle p \rangle=  \int\limits_{-\infty}^{\infty} \overline{\Psi}  \left(- i\hbar\frac{d}{dx}\right) \Psi \, d x $$ And I can read clearly that operator for momentum equals $\widehat{p}=- i\hbar\frac{d}{dx}$. Is there an easy way to derive an expectation value for $\langle p^2 \rangle$ and its QM operator $\widehat{p^2}$? grep a file, but show several surrounding lines? Identifying genes from a list of genes Binary search (bisection) in Python Connection pooling in PHP How do airlines determine ticket prices? Word for resembling the truth How do we refer to the act of resembling the truth, regardless if it is indeed the truth?  Some context: suppose you are watching a film and the story bears a striking resemblance to "real life". Perhaps you remember similar events from your own background or the story has a strong internal coherence. So you feel that the story could be true, even though you know it is fictional. Or, as the legend has it, when Michelangelo finished his "Pietà" and the sculpture seemed so "real" and "natural" to him, that he was amazed that the sculpture couldn't talk. One last example: you hear the promises of a politician in election campaign and he seems to be telling the truth, but of course you have no way to figure out, beforehand, if he is being honest or not.  The word "likelihood" comes to mind, but this word suggests some kind of numerical (even statistical) evaluation, which is akin to "probability". The word I am looking for describes the feeling you get, which leads to a subjective "binary" judgement (either it resembles the truth or not).  In Portuguese, such word is "verossimilhança" (from Latin verum, truth + similis, similar). Deriving the conditional distributions of a multivariate normal distribution How do I copy a string to the clipboard? A good approximation of $(1+x)^n$ is $1+xn$ when $|x|n &lt;&lt; 1$.  Does this approximation have a name?  Any leads on estimating the error of the approximation? Is there a replacement for unistd.h for Windows (Visual C)? I'm porting a relatively simple console program written for Unix to the Windows platform (). All the source files include "unistd.h", which doesn't exist.  Removing it, I get complaints about misssing prototypes for 'srandom', 'random', and 'getopt'. I know I can replace the random functions, and I'm pretty sure I can find/hack-up a getopt implementation.    But I'm sure others have run into the same challenge.  My question is: is there a port of "unistd.h" to Windows? At least one containg those functions which do have a native Windows implementation - I don't need pipes or forking.  EDIT:  I know I can create my very own "unistd.h" which contains replacements for the things I need - especially in this case, since it is a limited set. But since it seems like a common problem, I was wondering if someone had done the work already for a bigger subset of the functionality.  Switching to a different compiler or environment isn't possible at work - I'm stuck with Visual Studio. I am buing assamble self PC for playing games.  I am wondering, all the drivers, which are most likely for Windows, can i just use them on Ubuntu?  So if i understand you right, it will automaticaly detect the drivers, no need for installs ? or it find custom drivers for ubuntu.  This is the setup, will there be any problem with it? How does Linux know where its swap partition is? I've read that you need to put the swap partition on HDD rather than SSD.   My questions are the following:    When and how is the "checking" done by the distribution (or something else) to find its Swap partition?  Does it happen during boot?  It just checks all available disks and searches for a partition with 'swap' flag?  What happens if there are several partitions like that?  Also, how many swap partitions do I need to have if I run, for example, two different distributions on the same disk, let's say Fedora and Ubuntu? Error sending edittext in java server.

React on global hotkey in a Java program on Windows/Linux/Mac? A Java6 application sits in the system tray. It needs to be activated using a hotkey (e.g. Super-G or Ctrl-Shift-L etc) and do something (e.g. showing an input box).

This answer got way more upvotes than the one I accepted.  I only noticed this today so changed the accepted answer.  Can I get a notification email when an answer gets say 10 more votes than the one I accepted.  Just to let me know something might be up. I need help to advance in the resolution of that limit: $ \lim_{n \to \infty}{\sqrt[n]{\frac{n!}{n^n}}} $
