How can I make the item label in the description environment wrap?
force long text inside \item[{\texttt{}] to wrap
Summary table with a field that shows components of each summarized record I have a table with 2 fields the first is for community and the second for the main community that it belongs to, as in the image  I want to summarize the second field (Belongs_to) but with an extra field (multiple value field) that shows components of each main community, as in the image  Could anyone help me please? I own a notebook running Ubuntu 16.04 with Unity DE that does not have any keyboard LEDs to indicate NUM-Lock or CAPS-Lock states.  It would be useful for me to see them anyway, ideally through an indicator in Unity's panel.   Please note that I only want to see the states of NUM-Lock, CAPS-Lock and optionally Scroll-Lock. I do not want to see whether any other modifier keys like Shift, Ctrl, Alt, Super etc. are currently pressed. I only want a replacement for my missing LEDs.  Are there any working indicators available?    I already have read , but it does not suit my needs. indicator-xkbmod only displays a wrong icon but does not react on keyboard NUM-/CAPS-Lock status changes, kbstate is for KDE only and key-mon does not show the NUM-/CAPS-Lock states but indicates key presses to modifier keys. Pagination returns 404 after page 20 Exploring $ \sum_{n=0}^\infty \frac{n^p}{n!} = B_pe$, particularly $p = 2$. I was exploring the fact that $$ \sum_{n=0}^\infty \frac{n^p}{n!} = B_pe,$$ where $B_n$ is the $n$th Bell number.   I found this result by exploring the series on wolframalpha and looking up the sequence of numbers generated. I have no experience with Bell numbers other than knowing that they represent the number of ways of partitioning a set.   What I tried  Looking at the base case we can verify $$\sum_{n=0}^\infty \frac{n}{n!} = \sum_{n=1}^\infty \frac{1}{(n-1)!} = e. $$  But then I realize that $n^2$ is going to be difficult.  Specifically what I want  I am doing this for fun, so I just want to glean some sort of lesson out of this. Resources that let me learn for myself are just as good!   An accepted answer will have any one of the following:   A proof that $\sum_{n = 0}^{\infty} \frac{n^2}{n!} = 2e$ (this interests me a lot) A description of why this series is related to Bell numbers and the number of partitions of a set A link to some resource that introduces Bell numbers and/or their connection to this series. From the Windows NT-based (Windows XP and 7 specifically) command prompt, how can I get the serial number of a hard drive as a variable? The one I'm looking at is the serial number of the physical hard disk drive java.net.SocketException: Connection reset Does the sum of reciprocals of primes converge? Is this series known to converge, and if so, what does it converge to (if known)?  Where $p_n$ is prime number $n$, and $p_1 = 2$,  $$\sum\limits_{n=1}^\infty \frac{1}{p_n}$$ In the addon ArchiMesh there is a Japaneses curtain feature, but, it looks straight and does not have the fold that I want in it. Is there an addon that can do this for me? If not, how can I make a curtain (like in the images below)? Eclipse Optimize Imports to Include Static Imports Is there anyway to get Eclipse to automatically look for static imports? For example, now that I've finally upgraded to Junit 4, I'd like to be able to write:  assertEquals(expectedValue, actualValue);   hit Ctrl + Shift + O and have Eclipse add:  import static org.junit.Assert.assertEquals;   Maybe I'm asking too much. Correlated joint normal distribution: calculating a probability Given   $$ f_{XY}(x,y) = \frac{1}{2\pi \sqrt{1-\rho^2}} \exp \left( -\frac{x^2 +y^2 - 2\rho xy}{2(1-\rho^2)} \right) $$  $Y = Z\sqrt{1-\rho^2} + \rho X$  And   $$ f_{XZ}(x,z) = \frac{1}{2\pi } \exp \left( -\frac{x^2 +z^2}{2} \right) $$  Show that $P(X&gt;0,Y&gt;0)= \frac{1}{4}+\frac{1}{2\pi}(\arcsin \rho) $  I'm supposed to use the fact that X and Z are independent standard normal random variables, but I don't quite understand how. Any help would be greatly appreciated.

Bottom to top explanation of the Mahalanobis distance? How to shut down Ubuntu 11.10 host from within a Windows 7 VirtualBox guest? Use the values of \title, \author and \date on a custom title page I am trying to create a title page of my own.  Is there a way to make use of the \title, \author and \date commands inside the title page?  For instance:  ... \title{Something Cool} \author{Cool Dude} \date{\today}  \begin{document} \begin{titlepage}  The title is \title It was written by \author on \date  \end{titlepage} \end{document}   Basically I just want to know if there is a way to leverage the information stored in \title, \author and \date inside the title page. Why am I getting a NoClassDefFoundError in Java? Pass An Instantiated System.Type as a Type Parameter for a Generic Class I just can't seem to figure this one out.  I want to use the command line to connect to a MySQL database residing on another server.  I went ahead and created the username and password for the user.  I have also granted all privileges on that user for that database.  When using the command: mysql -h &lt;hostname&gt; -u &lt;username&gt; -p, I get the following error:  ERROR 1045 (28000): Access denied for user '&lt;username&gt;'@'&lt;local_machine_hostname&gt;' (using password: YES)   The problem is that it keeps appending the current machine's hostname into the username.  Obviously, that user@&lt;local_machine_hostname&gt; is not correct.  It doesn't matter what I type.  For instance, if I type:  mysql -h &lt;hostname&gt; -u '&lt;username&gt;'@'&lt;hostname&gt;' -p   It does the same, only in the error output, it says:  Access denied for user '&lt;username&gt;@&lt;hostname&gt;'@'&lt;local_machine_hostname&gt;'   Is there a setting in a configuration file which is allowing this to happen?  It's really quite annoying.  I need to set up a tikiwiki server, and it cannot connect because during the step where you set up mysql, it keeps appending the local machine's hostname to the mysql login name.
