Myself is Divya.. i am new to Linux/Unix.. i have a question on user and group management..  I read that for deleting a group a group must be empty..  I want to delete a primary group without deleting the users(as they belongs to other groups which is their secondary group)  for example I want to delete a group called ABC which contains the users U1,U2,U3,U4 whereas U1 and U4 belongs to another secondary group called DEF and GHI respectively.  ABC is the primary group for U1 and U4. let me know he command/s..  Thanks
I added a user account to the admin group and discovered I added wrong user. So I now have to remove the account from the admin group.   How can I remove an account from a group without deleting the user?
Center Gravity in Unity Chrome browser will not connect to intranet web addresses Can I mix different RAM modules in PC? I have 4 RAM slots on the motherboard P5K. At the moment I have two 1GB RAM modules and two 2GB RAM modules. Everything is working fine.   Can I buy one 4GB module and put it instead of the 1GB module?  Another question, can I mix MHz values, like that I have two 667MHz modules and two 1066MHz modules? Is this dangerous for the comp? Automatically solve dependencies of deb packages while using dpkg -i Installing Deb packages on the command line, using dpkg -i, only installs the package in question and displays errors of unresolved dependencies (manually solved by apt-geting the packages it complains about). How do I automatically resolve dependencies when installing standalone packages? Where can I see my full list of Questions and Answers in my profile page of Stack Exchange Android App? I want to see all my Questions and Answers in a particular SE site -  - profile page through Stack Exchange Android App. How can I see that? When I tried to see that I found only Top Posts(5) and Top Tags. I want to prove, that $GL(n,K)$ is open in $M(n,K)$, where ($K=\{\mathbb{R},\mathbb{C},\mathbb{H}\}$.  For the prove I don't want to use that the determinant is continous. Alternativly I assume a submultiplicative norm.  First step: Define $U_A:=\{B\in M(n,K):\Vert A-B\Vert&lt;\frac{1}{\Vert A^{-1}\Vert}\}$ and show that it is a neighbourhod of $A$ in $M(n,K)$.  Second step: I show that the series $\sum_{k\ge0}(1-A^{-1}B)^kA^{-1}$ converges absolutely and the limit is inverse to $B$.  For the second step I should use the Neumann series, right? But I have some problems with the first step. Any help? How to hear my voice in speakers with a mic? Passing functions to setTimeout in a loop: always the last value? Which is the best workflow to follow when texturing and importing textures from Substance Painter? So, I'm planning to texture a model using Substance Painter and will render it using the Cycles Render Engine. I will be also using the Principle Shader, heavily, to achieve realistic renders. So, which workflow in Substance Painter so that the textures are accurately rendered in Blender? Specular-Glossy? Or should I go with Metalic-Roughness? Is it still bad to use swap on a modern SSD? I have a Samsung 960 Pro SSD with Ubuntu 18.04  is it safe to put the swap file on there or would it hurt it in the long run,  I heard some people saying that new SSDs don't suffer from that issue anymore, is this true? Are drops in Google ranking common after switching to https? About a week ago I made the switch to https on one of my sites. I'm positive I did everything right. Properly setup 301 redirects from http to https versions. Added and verified https version in Webmaster Tools. Updated all internal links. Submitted new sitemap.  Despite that, many of my pages (about 40%) lost their rankings almost immediately. Those that dropped went from page 1 to nowhere. I can still see them indexed if I search for the URL, but otherwise it's like Google doesn't know they exist.  SSL Labs shows an "A" when I run their test and I have no manual actions showing in Webmaster Tools.  This is really frustrating. I don't actually need SSL, but Google finally scared me into it. Now I'm regretting the switch and contemplating going back to non-secured URLs.  Anything else I could have missed? A Strict Sense Stationary (SSS) process implies it is a Wide Sense Stationary (WSS) process - proof Looking for a mathematical proof which shows that a Strict Sense Stationary (SSS) process is necessarily a Wide Sense Stationary (WSS) process. Maximum total distance between points on a sphere What is the configuration (set of locations) of $n$ points on the surface of a sphere such that the sum of distances is maximum for $n=1,2,3,...$?  The sum of distances is measured by summing the lengths of every straight line (through the sphere) connecting every possible combination of $2$ points.  All the points are on a single sphere of radius $R$.  Here's a visualization:   Acknowledgements: Based on  Physics S.E. question. Image from . How do I set my DNS when resolv.conf is being overwritten? Most of the info I see online says to edit /etc/resolv.conf, but any changes I make there just get overridden.  $ cat /etc/resolv.conf  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) #     DO NOT EDIT THIS FILE BY HAND --  #     YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.1.1   It seems that 127.0.1.1 is a local instance of dnsmasq. The dnsmasq docs say to edit /etc/resolv.conf. I tried putting custom nameservers in /etc/resolv.conf.d/base, but the changes didn't show up in /etc/resolv.conf after running sudo resolvconf -u.  FYI, I don't want to change DNS on a per-connection basis, I want to set default DNS settings to use for all connections when not otherwise specified.  UPDATE:  I answered this question myself:   I think it's the best solution since:   It works. It requires the least amount of changes and It still works in conjunction with dnsmasq's DNS cache, rather than bypassing it. I know this has probably been asked before, but I couldn't find it with Google.   Given   Linux Kernel No configurations that change $HOME bash   Will ~ == $HOME be true? How can I animate the Restrict Visibility property of an object? I've got a "diagnostics" page in my ASP.NET application which does things like verify the database connection(s), display the current appSettings and ConnectionStrings, etc.  A section of this page displays the Assembly versions of important types used throughout, but I could not figure out how to effectively show the versions of ALL of the loaded assemblies.  What is the most effective way to figure out all currently referenced and/or loaded Assemblies in a .NET application?  Note: I'm not interested in file-based methods, like iterating through *.dll in a particular directory.  I am interested in what the application is actually using right now. Output from ls has newlines but displays on a single line. Why? Do votes get canceled if voting privilege is lost? If I'm below 15 reputation, I can't alter the public score of an answer/question.  Suppose I gain the privilege by getting the required rep and vote some posts up. Then, for any reason, I fall below 15 and lose the ability to vote. What about the votes I already did cast?  Do post scores get altered by ignoring my vote, or will they stay the same? In other words, is losing a privilege retroactive?  If yes, what about when I gain my privilege back? Are my votes automatically restored, or do I have to cast them again from scratch?  I made the easiest example, but this applies to any higher privilege How do I restore a Places folder I accidentally deleted in Nautilus? I accidentally deleted my Documents folder and didn't notice it for a couple days. Somewhere in that time, Nautilus auto-updated my list of Places so it no longer includes my Documents folder. I have since restored my Documents folder, but the Places link is still missing. How do I get it back?
