What do you do in Dungeon World when someone wants to perform an action they don't have a move for? Preventing other users from viewing my files Ref:   My Ubuntu user account name "user-3121" with type as "Administrator". There is one more account named "admin" with type as "Administrator". How can I be sure whether or not "admin" can login as me or otherwise view my files in "user-3121"?  I discussed this with the other user and we have tried to modify /etc/sudoers to protect my files:  Cmnd_Alias   SHELLS = /bin/sh,/bin/bash,/bin/ksh, /usr/bin/x11/passwd  Cmnd_Alias   SU = /usr/bin/su,/bin/su,/usr/bin/gksudo,/usr/bin/sudo,/usr/bin/su bash,/usr/bin/sudo /bin/bash,/usr/sbin/visudo  Cmnd_Alias   PASS = /usr/bin/passwd root,/bin/* * root,/bin/* * sysadmin,/bin/* * /home/sysadmin,/usr/bin/passwd  Cmnd_Alias      EDIT= /bin/* /etc/sudoers,/bin/* sudoers,/bin/* /etc/passwd,/bin/* passwd,/bin/* /etc/group,/bin/* group,/bin/* /etc/shadow,/bin/* shadow,/*/*/[a-z]* /etc/sudoers,/*/*/[a-z]* /etc/passwd,/*/*/[a-z]* /etc/group,/*/*/[a-z]* /etc/shadow,/*/*/[a-z]* sudoers,/*/*/[a-z]* passwd,/*/*/[a-z]* group,/*/*/[a-z]* shadow  Cmnd_Alias   CMDS = /usr/sbin/userdel * sysadmin,/usr/sbin/userdel sysadmin,/usr/sbin/deluser * sysadmin,/usr/sbin/deluser sysadmin  root    ALL=(ALL) ALL, !CMDS  %admin ALL=(ALL) ALL, !SHELLS, !SU, !CMDS, !PASS, !EDIT %sudo  ALL=(ALL) ALL,!SHELLS, !SU, !CMDS, !PASS, !EDIT  admin ALL=(ALL) ALL administrator ALL=(ALL) ALL   If "admin" can still read my data, how do I prevent that?  Also how does this configuration work, it allows "user-3121" to run some sudo commands, but it doesn't actually mention "user-3121" anywhere?  P.S. I'm the only person who knows the password for the "root" user, so that I can log in as root using the "su" command. Question I use pgfplots with the ultra thick option ans without explicitly giving the domain for the y-axis. It seems that in this case, some part of my graph is &quot;eaten&quot; by the margin: see the picture below to understand what I mean. Is there a way to avoid this? Code \documentclass{article} \usepackage{pgfplots} \begin{document}  \begin{tikzpicture}  \pgfplotsset{every axis/.append style={                     axis x line=middle,    % put the x axis in the middle                     axis y line=middle,    % put the y axis in the middle                     axis line style={-&gt;},  % arrows on the axis                     xlabel={$x$},          % default put x on x-axis                     ylabel={$y$},          % default put y on y-axis                     grid = major                     }}  \begin{axis}[xmin=-5,xmax=5] \addplot[orange,smooth, ultra thick] {sin(deg(x))} ;                  \end{axis} \end{tikzpicture}  \end{document} When I login, nothing happens.   I am presented with my desktop wallpaper.    No Dash, no Launcher, nothing. Infinite DeMorgan laws Let $X$ be a set and $\{Y_\alpha\}$ is infinite system of some subsets of $X$. Is it true that: $$\bigcup_\alpha(X\setminus Y_\alpha)=X\setminus\bigcap_\alpha Y_\alpha,$$ $$\bigcap_\alpha(X\setminus Y_\alpha)=X\setminus\bigcup_\alpha Y_\alpha.$$ (infinite DeMorgan laws)  Thanks a lot! When installing software in debian systems we can put something like this:   sudo apt-get install -y chromium-browser  that way the installation occurs automatically, whitout asking to confirm installation [Y/n]. Can i do the same with pacman? Multiplicative inverse questions This is my first time posting on Math exchange. I have been self-teaching myself Mathematics and recently started learning some Algebra. I was posed the following questions, in which I would like to answer before I proceed, but having some trouble finding proper solutions. So the format will be question, and my answer.      What name do we give an element $a \in \mathbb{Z}_n$ that has a multiplicative inverse?   A modular multiplicative inverse of an integer $a$ is an integer $x$ such that $ax \cong 1 (\mod m)$. This means that the remainder after dividing $ax$ by integer $m$ is equal to $1$.      Give an example, for some $n \in \mathbb{N}$, of an element of $\mathbb{Z}_n$, that does not have a multiplicative inverse?   This question is throwing me off because - does the $n$ we speak of matter for both $n \in \mathbb{N}$ and $\mathbb{Z}_n$ ot solely $n$? My guess here would be $0$ because we cannot have an inverse of $0$.      Prove that multiplicative inverse are unique; an element $a \in \mathbb{Z}_n$ cannot have two multiplicative inverses.    Suppose that an element $a\in\mathbb{Z}_n$ has an inverse $a'$. Next, suppose that $a^*$ is also an inverse of $a$. Then, $a'$ is a solution to $a \cdot_n x=1$, and similarly $a^*$ has a solution to $a \cdot_n x=1$.   Lemma: Suppose $a'$ is multiplicative inverse of $a$ in $\mathbb{Z}_n$, then for any $b \in \mathbb{Z}_n$ the equation $a \cdot_n x=b$ has a unique solution, such that $x = a' \cdot_n b$.   By Lemma, equation $a \cdot_n x = 1$ has a unique solution, namely $x=a'=a^*$. Therefore, an element $a\in \mathbb{Z}_n$ cannot have two multiplicative inverses.    Thank you for the help. I would love any constructive feedback for these. If you can help me elaborate on some ideas, that would be really helpful also.  Thank you very much! Computing matrix-vector calculus derivatives $x, a$ in $\mathbb R^n$, $A$ in $\mathbb  R^{n\times n}$. Compute $d(x^T a)/dx$ and $d(x^T A x)/dx$.  I'm not sure about how to think about these and how to do these. Can someone explain how to derive the expressions for the two?  Finally, what happens when we have $A$ and $X$, BOTH in $\mathbb R^{n\times n}$, and we want to find $dTrace(XA)/dX$? I just rememebered a case when I was still in school: we had to write an essay about a specific topic and one guy put big parts of his essay on Wikipedia before handing it in. When the teacher checked for plagiarism she indeed found big parts of his text in the Wikipedia article and thus accused him of plagiarism.  How would that situation be with journal papers (or other "official" ways of publishing)?  Can I reuse part(s) of texts I wrote myself but that are available publicly/online like on Wikipedia, my Blog, university homepage, etc.?  (Maybe consider that pseudonyms are used on Wikipedia, Blogs, etc.) Proving that $\frac{\phi^{400}+1}{\phi^{200}}$ is an integer. How do we prove that $\dfrac{\phi^{400}+1}{\phi^{200}}$ is an integer, where $\phi$ is the golden ratio?  This appeared in an answer to a  I asked previously, but I do not see how to prove this.. My screen has 1280 x 1024 resolution. But unfortunately, rightmost belt of 200 pixels is damaged and unable do display any image.  How can I set that the Xorg will treat my screen as 1080 x 1024 device?  Now I have tried:  Virtual 1080 1024 Viewport 0 0   It doesn't work right - image is scaled to fit vertically, and horizontally I can pan with the mouse. "print()" is producing undesired output in Visual Studio Code What are the possible catch bonuses and how much experience do they reward? My regex is matching too much. How do I make it stop? I have this gigantic ugly string: J0000000: Transaction A0001401 started on 8/22/2008 9:49:29 AM J0000010: Project name: E:\foo.pf J0000011: Job name: MBiek Direct Mail Test J0000020: Document 1 - Completed successfully  I'm trying to extract pieces from it using regex. In this case, I want to grab everything after Project Name up to the part where it says J0000011: (the 11 is going to be a different number every time). Here's the regex I've been playing with: Project name:\s+(.*)\s+J[0-9]{7}:  The problem is that it doesn't stop until it hits the J0000020: at the end. How do I make the regex stop at the first occurrence of J[0-9]{7}? If we have a point charge and outside of it we have a non-conducting Gaussian sphere, then Gauss's law says that the net flux should be zero. I agree that the total field lines coming in are equal to the number of field lines coming out, but isn't it true that the magnitude of the electric field at those segments of the sphere where the field is coming in is greater than those where it is coming out? So when we integrate, wouldn't these areas, having a greater electric field, contribute more to the net flux? I don't see why they would cancel each other out. grub2 not able to find the new kernel This is very strange issue, i have CentOS7 running on HP server and everything was working till date until i did "yum install kernel" after reboot it drop me in grub&gt; shell that means it won't able to read or find grub.conf file.   in grub&gt; i found grub.conf has still old files there is no new entries of new kernel   I did this, and found there is no new kernel entries but if i boot with old kernel then i can see latest grub.conf (with new kernel)  grub&gt;cat /grub2/grub.conf   Question: where grub2 getting that old file from? why it's not able to find new kernel ? Is "Call me when you are available to talk" correct? Call me when you are available to talk   Is that correct? Can I use it that way? How to create posters using LaTeX How do you factorise $x^3z - x^3y - y^3z + yz^3 + xy^3 - xz^3$? I'm trying to factorise $$ x^3z - x^3y - y^3z + yz^3 + xy^3 - xz^3 $$ into four linear factors.  By plugging it into WolframAlpha I've learned that it's $$-(x-y)(x-z)(y-z)(x+y+z)$$  My question is: what are the steps involved in factorising the expression? Is there a method I don't know about that I'd have access to with my limited maths?  Really appreciate any help! Which graphics formats can be included in documents processed by latex or pdflatex? There several types of graphics files. In no particular order .jpeg .eps .pdf .png .tif .jif (and no doubt others). Some work with latex, dvips and some work with pdflatex. How am I supposed to know which?  Just to confuse matters, metapost produces .eps but I can use these with pdflatex as long as I put in a four line incantation.  Can anyone explain this?
