I'm sure there is already such a question, but after searching I didn't find anything.  I'm looking for the method that would make \sim stretch depending on the text above.  Here is the example of what I need.
I am able to produce a standard length \sim with a tiny S above it, but I would like the \sim tilde to be longer (maybe one and half times as wide as a capital letter).  Any tips on how to change the width/length of \sim?
Restore SQL Server 2012 backup to a SQL Server 2008 database? How to copy files into /usr/local/? (permission denied) I'm still a little new to Ubuntu and was wondering how I can copy files, in this case Aptana Studio, to /usr/local/ without being denied.   Is there a way to do it in terminal? Or a way to allow myself permission?  I should add that I am using 10.10 Desktop edition, not server.

I am a UI designer and developer and have been designing websites for aound 10 years. I want to get into user experience design. I know how to do a design, but I am lagging the terminologies and the technical things in the user experience field.   So how do I go about getting the skills and mindset necessary for being a User Experience Designer? Repeating an equation including its content and number I would like to re-use equations with the same content and number. I know that the thmtools package has a restatable environment to do this for environments (like in ), but I would also like to do this with a single equation that is only part of some environment.  I had a look at the following questions which only aim at repeating the equation number but typing the whole equation twice (the first three) or repeat the content of the equation without a number (the last one):         Based on the answers provided there and on the  I tried to create a macro \restatableeq for restable equations like this:  \documentclass{article}  \usepackage{amsmath}  \newcommand{\restatableeq}[3]{\label{#3}#2\xdef#1{\unexpanded#2\unexpanded\tag{\unexpanded\ref{#3}}}}  \begin{document}  \begin{eqnarray} \restatableeq{\eqone}{This &amp; is &amp; eqation 1}{eq1}\\ Another &amp; simple &amp; equation \end{eqnarray}  \begin{eqnarray} One &amp; more &amp; equation\\ \restatableeq{\eqtwo}{This &amp; is &amp; eqation 2}{eq2} \end{eqnarray}  Here, we use (\ref{eq1}) and (\ref{eq2}) again: \begin{eqnarray*} \eqone\\ \eqtwo \end{eqnarray*}  \end{document}   Unfortunately, it does not work and yields:  ! Missing { inserted. &lt;to be read again&gt;                    T l.10 ...ableeq{\eqone}{This &amp; is &amp; eqation 1}{eq1}                                                   \\ ?   My guess is that the &amp; symbols are not treated as intended but I may well be wrong there.  How can I define a command like \restatableeq that allows me to re-use equations with the same content and number in a setting like in this example (and give it a label such that I can still use \ref as usual in addition to that)? Until recently  had one single reputation point, you can see it in this old screenshot:    Now it has over 2K reputation all of a sudden.. what has caused this? Has it affected "real" members as well? I would really love to play wizard/warlock multiclass with low charisma (just 13 for mutliclass). The handbook says that I can use Pact Magic slots to cast wizard spells, but doesn't specify which ability I use for spellcasting.     Pact Magic.   If you have both the Spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the Spellcasting class feature, and [vice versa].   When I cast wizard spells using Pact Magic slots (or warlock spells using wizard's "Spellcasting" slots) do I use spellcasting ability of the slot, or do I get to choose? Look at the profile page of , who has just "lost" 100k reputation and all their bronze badges, because of this broken design.

Merge two unadjacent partitions I have three partitions on my drive, arranged something like the following:   ___________ | 1 |  2 | 3| -------------   I wish to merge partitions 1 and 3.  Is there a way to do this, or do I have to manually "slide" partition 2 over to partition 3, and then merge the newly open space where partition 2 used to be?  Note: I do not have the space to copy partition 2 to partition 3 (2 is 200GB and 3 is 65GB). Holmby Hall is a landmark site in Los Angeles.

There is an option to filter only one color (R,G,B,Y) in my camera. What I want to know is can this effect be achieved in photoshop? And what is this called? I tried googling monochrome and came up with nothing. My camera calls it part color.

I haven't written any C++ in years and now I'm trying to get back into it. I then ran across this and thought about giving up:  typedef enum TokenType {     blah1   = 0x00000000,     blah2   = 0X01000000,     blah3   = 0X02000000 } TokenType;   What is this? Why is the typedef keyword used here? Why does the name TokenType appear twice in this declaration? How are the semantics different from this:  enum TokenType {     blah1 = 0x00000000,     blah2=0x01000000,     blah3=0x02000000 };
