pgf tikz polaraxis: Alignment of labels after rotation
Polar Plot x and y ticks and units
Does it exist a free interactive geometry software, like GeoGebra, which works for 3D geometry? I would be able to draw spheres, great circles, and so on. The setuid permission bit tells Linux to run a program with the effective user id of the owner instead of the executor:  &gt; cat setuid-test.c  #include &lt;stdio.h&gt; #include &lt;unistd.h&gt;  int main(int argc, char** argv) {     printf("%d", geteuid());     return 0; }  &gt; gcc -o setuid-test setuid-test.c &gt; ./setuid-test  1000  &gt; sudo chown nobody ./setuid-test; sudo chmod +s ./setuid-test &gt; ./setuid-test  65534   However, this only applies to executables; shell scripts ignore the setuid bit:  &gt; cat setuid-test2  #!/bin/bash id -u  &gt; ./setuid-test2  1000  &gt; sudo chown nobody ./setuid-test2; sudo chmod +s ./setuid-test2 &gt; ./setuid-test2  1000     Wikipedia :     Due to the increased likelihood of security flaws, many operating systems ignore the setuid attribute when applied to executable shell scripts.   Assuming I'm willing to accept those risks, is there any way to tell Linux to treat the setuid bit the same on shell scripts as it does on executables?  If not, is there a common workaround for this problem? My current solution is to add a sudoers entry to allow ALL to run a given script as the user I want it run as, with NOPASSWD to avoid the password prompt. The main downsides to that is the need for a sudoers entry every time I want to do this, and the need for the caller to sudo some-script instead of just some-script what is the difference between kind, type and sort Show hidden files on Mac OS X Mojave using Terminal To see my /etc folder I've tried this command in Terminal:  sudo chflags nohidden /etc   followed by:  sudo defaults write com.apple.Finder AppleShowAllFiles true; killall Finder   also tried:  sudo defaults write com.apple.Finder AppleShowAllFiles YES; killall Finder   Neither of them seemed to work. Argument in "thebibliography" I was reading the explanation about  and was totally confused:     The thebibliography environment has an argument which should be a string at least the length of the widest entry label in the source list. Instead of using the numbers generated by the environment as entry labels, you can specify your own by using an optional argument to \bibitem, but remember to increase the length of the argument to the thebibliography command.    What does "widest entry label" mean? Practically, what should I put as the argument in   \begin{thebibliography}{?}   or is the argument not necessary? How to check for an active Internet connection on iOS or macOS? Unable to play MP3 or MP4 files in Rhythmbox or Movie Player I am unable to play any MP3 or MP4 files. When I try to open any MP3 or MP4 file, both show an error, a Python 2.7 plug-in is required. How to Start Web Mapping? Activate physics by keyframe I'd like to have a group of debris fall from a ceiling onto the floor, but not have them drop all at the same time. Is there a way to set a keyframe that dictates when the object enters the simulation? For example, object 1 starts falling on frame 0, object 2 on frame 5, object 3 on frame 24, etc. $F$ closed and connected then... Let $F\subset X$ be a closed and connected subset of the metric space $(X,d)$ then for every pair of points $a, b\in F$ and each $\epsilon&gt;0$ there are points $a=z_0,z_1,\ldots z_n=b$ in $F$ such that $d(z_{k-1}-z_k)&lt;\epsilon$ for $1\leq k\leq n$.  Is the hypothesis that $F$ is closed needed? I will be transferring between two international flights at Tokyo Narita airport. I'm scheduled to depart the same day I arrive. I am planning to stay within the airport during the layover. Does anyone know if I will require a transit visa at Narita? Do mindless creatures get feats? Do creatures that have no Intelligence Score ("Int —" in the stat block) gain Feats? I'm creating some monsters but I failed to find the answer for this question. I am running Xubuntu 11.10 and everything works nicely. I have selected a nice Xfce theme and everything looks beautiful, except Libreoffice.  While other programmes (Gimp, Inkscape, Thunar etc.) integrate with the selected Appearance &amp; Window Manager theme, Libreoffice looks like a Windows 98 programme.  Does anyone know how to fix this? I have already tried this solution, without success:   Thanks for your help! Inserting newlines in Rectangle Text elements via ArcPy causes overlap? I ran across an issue the other day when I tried to use ArcPy's mapping module to edit rectangle text elements with newlines (\n) in an ArcMap document.  Here's what the output looked like:    Here's the code I used to generate that output.  The first column are rectangle text elements Text1, Text2, Text3 going down; the second column are "plain" text elements Text4, Text5, and Text6 going down.  import os import arcpy  HomeDir = r"C:\Desktop" arcpy.env.workspace = HomeDir  CurrentMXD = arcpy.mapping.MapDocument(r"C:\Desktop\TextTest.mxd") OutputFilename = r"C:\Desktop\TextTest.pdf" if os.path.exists(OutputFilename):     os.remove(OutputFilename)  for TextElement in arcpy.mapping.ListLayoutElements(CurrentMXD, "TEXT_ELEMENT"):     TextElementName = TextElement.name      String1 = "The quick brown fox jumped over the lazy dog.\nShe sells sea shells by the sea shore."     String2 = "The quick brown fox \njumped over the lazy dog.\nShe sells sea shells by the sea shore."     String3 = "The quick brown fox jumped \nover the lazy dog.\nShe sells sea shells by the sea shore."      if TextElementName == "Text1":         TextElement.text = String1     if TextElementName == "Text2":         TextElement.text = String2      if TextElementName == "Text3":         TextElement.text = String3     if TextElementName == "Text4":         TextElement.text = String1     if TextElementName == "Text5":         TextElement.text = String2     if TextElementName == "Text6":         TextElement.text = String3  arcpy.mapping.ExportToPDF(CurrentMXD, OutputFilename)   So far, it looks like the presence of the messed up text depends on whether the line is longer enough to wrap, and whether the line before the newline is longer than the line after the newline.  Any ideas about what could be going wrong?  Is there a workaround?  I could use plain text elements and worry about wrapping lines using Python, but I'm hoping I can figure something out. Is $\mathbb{Z}[\sqrt{-7}]$ a UFD or not? Is $\mathbb{Z}[\sqrt{-7}]$ a UFD or not? I feel like there should be some easy example showing that it is not, but I can not think of one. Enable Careers and Jobs in app You can use the range feature of unicode-math to set the math font for a specific unicode slots or the macro accessing the glyph. I tried this with the sum sign &amp; Latin Modern, see my example:  \documentclass{scrartcl}  \usepackage{amsmath} \usepackage{unicode-math} % use unicode in math &amp; setup math fonts \setmathfont{Asana Math} %\setmathfont[range=\sum]{Latin Modern Math} % substitute Sum sign  \begin{document}  Notice the different sum sign $\sum$, as intended.   Notice also, the difference in spacing, not intended: \begin{equation}     \begin{bmatrix}         0           &amp; \frac{1}{2}   &amp; \frac{2}{3} \\         \frac{3}{4} &amp; 0             &amp; \frac{4}{5} \\         \frac{5}{6} &amp; \frac{6}{7}   &amp; 0     \end{bmatrix}     \begin{pmatrix}         A \\         B \\         C     \end{pmatrix} \end{equation} \end{document}   However, not only the sum sign, but also the spacing in the matrices changes. With Latin Modern commented out (as in the example):  With Latin Modern active (remove % before relevant line):  Why is that? BTW, I'm using Lualatex from TeXLive 2012. How to divide the money based on the below conditions? I know that who is used when asking about a subject (Who is at the door?) and whom is used when asking about an object (By whom was the door opened?). How do you determine which one to use when the object becomes the subject of another clause?   For example, take the sentence:      I gave the prize to ____ deserved it most.   Would it be whomever because it's the object of "gave," or would it be whoever because it's the subject of "deserved"? Is their a hard-and-fast rule to rely on in situations like this?
