I would like to add a tikz node within a text in such a way that it doesn't add space between the lines. In particular, I'd like to animate (in beamer) a frame around the text without it taking space.  Below is an example of what I'm trying to do.  Many thanks in advance!  \documentclass{beamer} \usepackage{tikz}  \tikzset{      alt/.code args={&lt;#1&gt;#2#3}{%        \alt&lt;#1&gt;{\pgfkeysalso{#2}}{\pgfkeysalso{#3}}      },     BeamerAlert/.style={alt=#1{draw=red,thick,rounded corners}{},anchor=base} }  \newcommand&lt;&gt;{\tikzMe}[1]{    \tikz[baseline]\node[BeamerAlert=#2] {${#1}$}; }  \begin{document} \begin{frame}   This is an \tikzMe&lt;2&gt;{\mathsf{example}} of   text with the space between lines changed because of the tikz   node. Here is another line whose spacing is natural.  \end{frame} \end{document}
Is there a simple way to reduce the amount of white space around the TikZ in the MWE pasted below (in particular in the x direction)?  \documentclass{article} \usepackage{xcolor} \usepackage{tikz}  \begin{document} VRCRCRCRCC \tikz[baseline] \node[fill=yellow!30, anchor=base,inner sep=0.7pt, outer xsep=-2pt] {ABCDE}; VBZBZBBBBG \end{document}     PS: This question may be a duplicate of . I posted it nevertheless since 1) my example is much simpler (and hence may have a much simpler solution) and 2) I don't see how the answers given there could help in my case. If you disagree feel free to mark my question as "exact (!) duplicate of ...".
I have a requirement to create triggers dynamically after a managed package is installed. I have read that the tooling API can be used to create triggers dynamically however it cannot be used in production. Is it possible to create triggers from a managed package in an org? I want to be able to create the trigger based on some user inputs. Does "it is entirely possible that" require the subjunctive form of the verb following "that"? Word for phrases that are examples of what they describe Convert a line drawing from raster to vector I have a raster image, basically a scanned drawing of the outlines (and some detail) of various objects, and I wish to convert these lines to vectors, using either Illustrator or Inkscape.  My present solution is to have the raster image as a background layer, and in a new layer above it I use the pen to follow the lines as close as possible.  Later I tweak these lines to fit the raster image better. That has worked fine for simple drawings. However for some of my extremely complex drawings, this is very tedious to do.  Is there any tool or filter of some sort that is capable of recognizing the lines in line drawings and creating vector paths from them? I have a song that Windows can't play because there is a question mark in the name of the file.  "Where Have All the Cowboys Gone?.ogg" // as an example   So I try to rename it and Windows complains whether I try it in Explorer or from command prompt.  Error I get when trying to copy, rename, or move is:     The Filename, directory name, or volume label syntax is incorrect   Is there a Windows way to force a rename in this case?   Update  I'll keep an eye on this question, but after 13 answers and many attempts (aside form 3rd party solutions) it seems that Windows can't do this (or at least my windows can't, no short names). So I'm accepting the answer which was my original solution anyway of using Linux. It would be nice to see Windows handle this somehow, so don't stop just because I've accepted this answer, the question still stands! I like to know when a dying star collapsed into a black hole, is there anything inside or on the event horizon that is interacting with higgs field? Aut $\mathbb Z_p\simeq \mathbb Z_{p-1}$ I know the so-called textbook definition of unit tests and integration tests.  What I am curious about is when it is time to write unit tests... I will write them to cover as many sets of classes as possible.  For example, if I have a Word class, I will write some unit tests for the Word class.  Then, I begin writing my Sentence class, and when it needs to interact with the Word class, I will often write my unit tests such that they test both Sentence and Word... at least in the places where they interact.  Have these tests essentially become integration tests because they now test the integration of these 2 classes, or is it just a unit test that spans 2 classes?  In general, because of this uncertain line, I will rarely actually write integration tests... or is my using the finished product to see if all the pieces work properly the actual integration tests, even though they are manual and rarely repeated beyond the scope of each individual feature?  Am I misunderstanding integration tests, or is there really just very little difference between integration and unit tests? I'm trying to find the name of a lower-budget science fiction film that was available for viewing on demands on MIT student cable in the late 1990s.  I suspect the film was made earlier in that decade, and it definitely seemed to have been influenced by RoboCop.  The plot involves characters is a somewhat dystopian near future.  One of the characters (named Hawkins, I think) is initially in a wheelchair, and that is interfering with his relationship with the woman he loves.  (He watches virtual reality simulations of himself having sex with her when he's alone at home.)  Maybe halfway through the movie, he decides there's no hope for their relationship, so he lets the bad guys turn him into a RoboCop-like cyborg.  I think he ends up fighting the other main characters, but I don't remember how the movie ends.  The film was clearly shot cheaply but competently.  The color palette was rather drab, I think, and there were few indoor sets.  It's possible that the film never got a normal release of any kind, since I don't know where the students at MIT cable got ahold of it.  So does anybody know what this film was? Prove $(x_1+.....+x_n)^2 \leq n(x_1^2 + .....+x_n^2)$ Prove that  $(x_1+\dots+x_n)^2 \leq n(x_1^2 + \dots+x_n^2)$  for all positive integers n and all real numbers $x_1,....,x_n$  I am attempting a proof by induction but wasn't sure if i need the Cauchy-Schwarz Inequality or perhaps another way other than induction to prove this.  Proof   $n=1$ true  assume true for $n=k$  Now for $n= k+1$  $(x_1 + \dots +x_k + x_{k+1})^2 \leq \dots$ How to fix very slow Ubuntu booting? How do I setup keyboard macros? In my daily life I'm always typing &lt;kbd&gt;Keyboard Character&lt;/kbd&gt; and I'd like to set up a macro in Ubuntu to automatically enter &lt;kbd&gt; &lt;/kbd&gt;.  I'd like to assign it to say Shift+Control+K or whatever keyboard control character combination isn't assigned and already used by Ubuntu.  Back in the day of TSR (Terminate and Stay Resident) MS-DOS programs this was possible. Certainly it must be in Ubuntu too?  Do I have to write a daemon to accomplish this?    I found other questions with no answers: ,   I found a similar question with an answer: . However that question stipulated the answer could not be AutoKey. I have a hard time formulating proofs.  For this problem, I  can see that if $n$ is equal to $8,$ this statement is true.  $(\mathbb{Z}/8\mathbb{Z})^{\times}$ includes elements:  $1,3,5,7$, and all of these are roots of $1-x^2 \pmod 8.$  And obviously $8$ divides $24.$  But how do I prove this without depending on number calculations and only using theorems?  Help Please?  I need a step by step walk through of how to do this proof and what theorems would be appropriate to use. Proving the second root of a quadratic equation If $\alpha$ is a root of the equation $4x^2+2x-1=0$, then prove that $4\alpha^3-3\alpha$ is the other root. How do I proceed? The sum of the roots, the product of the roots lead me nowhere. Should I find the roots of the equation and substitute in the given two expressions of $\alpha$ and check whether manipulating the first root gives me the second root (which seems much complicated), or is there any other way? I just learned about the C++ construct called "placement new".  It allows you to exactly control where a pointer points to in memory.  It looks like this:   #include &lt;new&gt;        // Must #include this to use "placement new"  #include "Fred.h"     // Declaration of class Fred   void someCode()  {    char memory[sizeof(Fred)];    void* place = memory;     Fred* f = new(place) Fred();   // Create a pointer to a Fred(),                                   // stored at "place"     // The pointers f and place will be equal     ...  }    (example from ) In this example, the this pointer of Fred will be equal to place.    I've seen it used in our team's code once or twice.  In your experience, what does this construct enable?  Do other pointer languages have similar constructs?  To me, it seems reminiscent of equivalence in FORTRAN, which allows disparate variables to occupy the same location in memory. Predefined Coordinate Systems missing in QGIS 2 in QGis 1.8 were lots of predefined coordinate systems (national projections). Where have they all gone in qgis 2.0? I specifically need the Gauß-Krüger-Projections Zone 1 to 5.  Is there any plugin to load those coordinate systems?

Given the function $f:A \to B$.  Let $C$ be a subset of $A$ and let $D$ be a subset of $B$.  Prove that:  $C$ is a subset of $f^{-1}[f(C)]$  So I have to show that every element of $C$ is in the set $f^{-1}[f(C)]$  I know that $f(C)$ is the image of $C$ in $B$ and that $f^{-1}[f(C)]$ is the pre-image of $f(C)$ into $A$.  Where I'm stuck is how to use all of this information to show/prove that $C$ is indeed a subset.    Do I start with an arbitrary element (hey, let's call it $x$) of $C$? and then show that $f^{-1}[f(x)]$ is $x$?  I could use a little direction here...  Thanks. Trying to figure what language this PDA (pushdown automata) accepts I have the following PDA and I can't figure our what words it accepts, would like to get some help with figuring this out.    Of course it only accepts if that stack is empty in the accepting state. Is there any text editor which supports Markdown (Ask Ubuntu's formatting style)?
