I have 2 Telegram accounts and i want to have both of them on my pc. Telegram has an  for ubuntu. but it only supports one account at the time.  My question is, How can i duplicate this application to use 2 Telegram account?
Is there a way to have two copies of  app in Ubuntu each with a different account?  It seems copying the app in another folder does not work.
I run sudo apt-get install git-all in Ubuntu 16.04 and see the following in the end  Setting up runit (2.1.2-3ubuntu1) ... start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused dpkg: error processing package runit (--configure):  subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of git-daemon-run:  git-daemon-run depends on runit; however:   Package runit is not configured yet.  dpkg: error processing package git-daemon-run (--configure):  dependency problems - leaving unconfigured No apport report written because the error message indicates its a followup error from a previous failure.                       Errors were encountered while processing:  runit  git-daemon-run E: Sub-process /usr/bin/dpkg returned an error code (1)   I get the error after rebooting my system also. It really blocks my whole system.  I run killall update-notifier. I run sudo apt-get install git-all but  I get the same error message. I run pgrep -a apt but get nothing as output. I run pgrep -a update but get nothing as output.  A bug report about the case .    In Grub, Choose Advanced options > Ubuntu (Upstart) Linux kernel 4.22. Doing the same only in terminal without systemd causes the same error.      Why is this error here with runit? What's the difference between using single and double quotation marks/inverted commas? Can I choose which records are copied in a Partial Copy sandbox? We have a partial copy sandbox that we're using for development and testing.  This is really helpful as some of our applications internally store Salesforce id's.  However, there is a limitation with the partial copy as it only brings in 10,000 records per object from the production environment.  Unfortunately some of the id's we internally store are not being brought down into our partial copy which causes errors.  The 10,000 records that it did copy over aren't needed; I realistically only need 1 or 2.  Is there any way I can achieve copying over a specific record from the production environment? How do I resolve slow and choppy performance in virtualbox? Ubuntu runs very slowly inside of VirtualBox.  How do I run Ubuntu with unity or enabled transparency smoothly with VirtualBox? Comma — a punctuation error? Consider:     This book provides a solid psychological understanding of these experiments, and adds a few expansions and conclusions of its own. It also provides …   My question regards the comma. I have been told that having the comma there is an error.  According to  this seems to be the case according to “some style guides”. The reason is that the stuff after the comma is not independent; it’s dependent on what comes before.  What do you think? It would seem to me the comma helps a lot, because those two “and”s without any comma make the sentence rather cluttered. That’s why I put the comma there. So I’m not sure. So, in my physics textbook it's written that the kinetic energy possessed by a body is equal to the amount of work done by an opposing force to stop the body, now that got me thinking that when a ball hits a wall, the wall which is the opposing force does no work  because there is no displacement, so to say isn't the kinetic energy possessed by the ball zero? How to do a generalized linear model with multiple dependent variables in R? I have six dependent variables (count data) and several independent variables, I see that in a MMR the script goes like this:  my.model &lt;- lm(cbind(DV1,DV2,DV3,DV4,DV5,DV6) ~ IV1 + IV2 + ... + IVn)   But, since my data are counts, I want to use a generalized linear model and I tried this:  my.model &lt;- glm(cbind(DV1,DV2,DV3,DV4,DV5,DV6) ~ IV1 + IV2 + ... + IVn, family="poisson")   And appears this error message:  Error in glm.fit(x = c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,  :    (subscript) logical subscript too long`   Can anyone explain me this error message or a way to solve my problem? What solutions does the equation $4x\equiv2\mod10$ have? (Hint, it will have more that one.) What about solutions to an equation $ax\equiv d\mod n$, where $d=\gcd(a,n)$?  This is the question that appeared in our universities last year paper. But it seems very difficult for me like for first part I am able to solve by simplifications I got $x=5\cdot Z +3$ as solution which makes sense and seems fair but for the second one, I have no idea how can I approach that. Can you please help me out with that one. I tried to simplify that by using Euclidean algorithm but still, I didn't get any idea that what actually the solution will be. My final exam is on 2nd of next month and because of covid I am unable to contact in person for any help. So any help from this site will be appreciated. Thank you for looking at this question! Is it good English to say "They have just left", when talking about a single person (perhaps someone you don't know the gender of)?  (I am a native English speaker, I'm looking for the view held by lexicographers). I've been programming in Java for a while and just got thrown onto a project that's written entirely in C#.  I'm trying to come up to speed in C#, and noticed enums used in several places in my new project, but at first glance, C#'s enums seem to be more simplistic than the Java 1.5+ implementation.  Can anyone enumerate the differences between C# and Java enums, and how to overcome the differences?  (I don't want to start a language flame war, I just want to know how to do some things in C# that I used to do in Java).  For example, could someone post a C# counterpart to Sun's famous Planet enum example?  public enum Planet {   MERCURY (3.303e+23, 2.4397e6),   VENUS   (4.869e+24, 6.0518e6),   EARTH   (5.976e+24, 6.37814e6),   MARS    (6.421e+23, 3.3972e6),   JUPITER (1.9e+27,   7.1492e7),   SATURN  (5.688e+26, 6.0268e7),   URANUS  (8.686e+25, 2.5559e7),   NEPTUNE (1.024e+26, 2.4746e7),   PLUTO   (1.27e+22,  1.137e6);    private final double mass;   // in kilograms   private final double radius; // in meters   Planet(double mass, double radius) {       this.mass = mass;       this.radius = radius;   }   public double mass()   { return mass; }   public double radius() { return radius; }    // universal gravitational constant  (m3 kg-1 s-2)   public static final double G = 6.67300E-11;    public double surfaceGravity() {       return G * mass / (radius * radius);   }   public double surfaceWeight(double otherMass) {       return otherMass * surfaceGravity();   } }  // Example usage (slight modification of Sun's example): public static void main(String[] args) {     Planet pEarth = Planet.EARTH;     double earthRadius = pEarth.radius(); // Just threw it in to show usage      // Argument passed in is earth Weight.  Calculate weight on each planet:     double earthWeight = Double.parseDouble(args[0]);     double mass = earthWeight/pEarth.surfaceGravity();     for (Planet p : Planet.values())        System.out.printf("Your weight on %s is %f%n",                          p, p.surfaceWeight(mass)); }  // Example output: $ java Planet 175 Your weight on MERCURY is 66.107583 Your weight on VENUS is 158.374842 [etc ...] Why Doesn't C# Allow Static Methods to Implement an Interface? Why was C# designed this way?  As I understand it, an interface only describes behaviour, and serves the purpose of describing a contractual obligation for classes implementing the interface that certain behaviour is implemented.  If classes wish to implement that behavour in a shared method, why shouldn't they?  Here is an example of what I have in mind:  // These items will be displayed in a list on the screen. public interface IListItem {   string ScreenName();   ... }  public class Animal: IListItem {     // All animals will be called "Animal".     public static string ScreenName() {         return "Animal";     } .... }  public class Person: IListItem {      private string name;      // All persons will be called by their individual names.     public string ScreenName() {         return name;     }      ....   } Is it okay to use the phrase "try and"? Is it grammatically correct? e.g. "I will try and answer ..." I read the following sentence in book (App).     I will try and answer any questions you ask.   Why don't they use the following? (it is much common):     I will try to answer any questions you ask.   Is there any difference in meaning?  Update:  I noticed that a lot of books and news websites are using this phrase:        Although Katty will try and answer as many questions as she can.    He puller would have a chance to try and answer the question on her own ... How to define a recurrence relation in Maple without the command proc? Find all solutions to the functional equation $f(x) +f(x+y)=y+2 $ I have a question about making an ending symbol.  It is a LaTex-default that every proof environment has an ending symbol. I want to make every theorem-alike environment such as the example environment have also an ending symbol. But how to manually set this up?

How can I define a custom listing environment? I am trying to define an enviroment for a specific programming language, F#. Here's my code:  \definecolor{bluekeywords}{rgb}{0.13,0.13,1} \definecolor{greencomments}{rgb}{0,0.5,0} \definecolor{turqusnumbers}{rgb}{0.17,0.57,0.69} \definecolor{redstrings}{rgb}{0.5,0,0}  \lstdefinelanguage{FSharp}     {morekeywords={let, new, match, with, rec, open, module, namespace, type, of, member, and, for, in, do, begin, end, fun, function, try, mutable, if, then, else},     keywordstyle=\color{bluekeywords},     sensitive=false,     morecomment=[l][\color{greencomments}]{///},     morecomment=[l][\color{greencomments}]{//},     morecomment=[s][\color{greencomments}]{{(*}{*)}},     morestring=[b]",     stringstyle=\color{redstrings}     }  \newenvironment{fslisting}   {     \lstset{         language=FSharp,         basicstyle=\ttfamily,         breaklines=true,         columns=fullflexible}     \begin{lstlisting}   }   {     \end{lstlisting}   }   Then I'm trying to use it as such:  \begin{fslisting} type 'a Process = 'a Signal IObservable \end{fslisting}   But it doesn't work. The output log says that the listing is not terminated - or is terminated by the document. So the rest of the document is also formatted as a listing, which is of course not the intention.  What am I doing wrong here? mysql select distinct rows into a comma delimited list column Which is the right way to do something like 'description' list but with customizable and fixed-width labels? I.e. something like this:  Label:         Text text text text text text                text text text text. Longer label:  Text text text text text text                Text text text text.   The way I see it to use two-column table (first columt for labels and second column for descriptions), but this solution seems ugly. Is there any other way? I tried to prove this question but without a success: Let $K_1$ and $K_2$ be definable sets, prove that $K_1\cup K_2$ is definable.  What I tried to do is to assume: $K_1=Ass(X)=\{ v|v \vDash X \}$ and $K_2=Ass(Y)=\{ v|v \vDash Y \}$ and to say that $K_1\cup K_2=Ass(X \cap Y)$. but I couldn't prove that: $K_1\cup K_2 \supseteq Ass(X \cap Y)$ .
