For Ubuntu 16.04 LTS version , I search up something about starting terminal window, but Ii think these are not updated,  When I search,     I go the way to open terminal automatically by GUI but from the line command not up-to-date, Could you help how to do complete this task over terminal,  Thanks, solfish
How could I get the terminal to be launched once I have logged in, so that typing commands is much simpler?
Is Linux Virtual Server old, or is it standing still? Based on this question: , LVS may be the right solution for my problem.   But when I went to its homepage , I found that LVS has been updated since Nov, 2008. The world's moving fast, and I don't know if LVS was obsolete or not.  Is LVS standing still, or there're some better solutions to replace it?  Thank you so much. Does a logistic regression maximizing likelihood necessarily also maximize AUC over linear models?

How to set the default program for opening files without an extension in Windows? I'm running the following script on Ubuntu 14.04:  #!/bin/bash  apt-get purge -y nginx apt-get install -y nginx  date   When I run it like cat /tmp/script | bash, apt-get starts installing, then "date" is printed (not the actual date, but the command name), then the remaining apt-get output is printed.  If however I run the script like /tmp/script, it works as expected: printing the date after apt-get finished.  Why does this happen and how can I force bash to work when being piped to the same way it does when invoked directly? Too many of your edits were rejected, try again in 7 days First time I've got the following message on SO:     Too many of your edits were rejected,   try again in 7 days.   Although, I have made ~50 accepted edits this day.  I'm sure that should outweigh the ~5 rejected edits, right?    My suggestion:  bool allowEdit(USER u) {     if(u.rejected * 5 &gt; u.accepted)         return(false);     else         return(true); }   Think of it this way: if I do a 1000 accepted edits, and mess up on 5 [rejected], does that mean I should get banned for 7 days?    Hmmm... There seems to be a bug; the message only appears when clicking edit from review.  But otherwise, I can't edit , even when going to it from the homepage. Distance learning: taken seriously? I'm currently in the first year of a six year bachelor's degree aiming for astrophysics. The course is a home/distance learning setup run by the Open University. While I am enjoying it thoroughly, I am aware of the academic politics that can dog professional science. So my question is thus: Upon soldiering on with the degree, then masters, and then PhD, will I be taken seriously within a professional setting given my inability to reference a leading university for my education? Will the format for my studying be "pitied"?   Edit: I suppose a bit more info may help. I'm 27,wife, 2 children, and I currently work as a full time chef, and self employed part time IT technician. I flunked my GCSEs, with no further education. The past 3 years have been a revelation for me, and I have discovered a before unexperienced love for academia; specifically, physics and astronomy. Last year I completed a 1 year OU maths brush up course, which at the time I really struggled with. This year I had a bout of madness and took the plunge for a BSc degree in astronomy. I am now loving the math within the physics so far (yet to hit calculus though!)  PhD, and even masters, is a long way off.  Also, since this original post I've improved my understanding of what a PhD actually entails. So I realise that if I get there, it may well not have anything to do with the OU!     It occurs to me that a lot of my initial queries could have been avoided with a better understanding of the educational and qualification system itself. I now have a greater appreciation as to what a PhD actually is, realising that its a long way off and not necessarily needed for a fulfilling career in research.  I think trying to repair my broken education and fight my way into a worthwhile (and productive!) career is enough of challenge at the moment. There will be plenty of time later for worries concerning doctorates.  It is good to hear that there is at least an open mind towards distance educated professionals.   As has been said, if you've got it, you've got it - you just have to be ready to prove it. Why don't C++ compilers define operator== and operator!=? Why can't I connect to Ubuntu One?

It says:  "Let $(E_k)_{k=1}^{\infty}$ be a countable collection of measurable sets for which $\sum_{k=1}^{\infty} m(E_k) &lt; \infty$. Then almost all x $\epsilon \ \mathbb{R}$ belong to at most finitely many of the $E_k$'s"  I don't get three things:   "Then almost all x $\in \ \mathbb{R}$ belong to at most finitely many of the $E_k$'s"   What does that mean? Since the Borel-Cantelli Lemma comes after the "almost everywhere" definition, I guess: $\exists \ Z \ \subset \mathbb{R}$ s.t. $m(Z) = 0$ and $\forall x \ \in \ \mathbb{R} \setminus Z$, x belongs to $(E_{j}, E_{j+1}, E_{l}, ..., E_{m})$.   In the proof, one can see the $m(\limsup \ E_k) = 0$ part, stated as $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$. For some reason, $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$ implies that "Therefore almost all x $\in \ \mathbb{R}$ fail to belong to $\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]$ and therefore belong to at most finitely many $E_k$'s"   Okay, why? What is the contradiction if almost all $x \epsilon \ \mathbb{R}$ belong to all the $E_k$'s? Or a countably infinite subcollection?   What is the significance of this? Why not just state the Borel-Cantelli Lemma as "Let $(E_k)_{k=1}^{\infty}$ be a countable collection of measurable sets for which $\sum_{k=1}^{\infty} m(E_k) &lt; \infty$. $m(\cap_{n=1}^{\infty} [\cup_{k=n}^{\infty} E_k]) = 0$"? How can I identify what application is using a given file? Mistakenly filed as Exempt from income tax witholdings for entire year 2019 I am a basic 30 year old filing Single, W2, healthy working individual. No dependents, no additional schedules, capital gains or losses other than Student Loan interest expense.   I started a new job in January 2019 and somehow during my new hire enrollment, "I or someone" marked in my file as Exempt... I am pretty familiar with filing my own 1040 (as its pretty basic)and I know for a fact that I would never for under any reason think that I am Exempt from absolutely anything tax related. Nobody in my new job's HR department reached out to confirm whether this Exemption was correct or not with me personally. My CPA said that anytime they receive an Exempt W-4 form, that they automatically return the form to the employer to confirm.   I unknowingly went 11 full months in 2019 without any taxes being withheld. Of course my paycheck was more than before, but I also got a better/higher salary job, so I never thought about the difference being from not paying taxes. And, no I do not print out my paystubs. It’s all through Paycom and it clearly shows you your gross pay &amp; a "$XXX" amount in deductions/withholdings - kicker is, you have to click the drop down menu to actually see the entire breakdown. At which point, I never saw the big $0 in taxes being withheld... I know the taxes have to be paid one way or another, but I don't feel like I should be entirely responsible for a $5k-$6k tax liability for a HR clerical error. Even if I did actually input it incorrectly the first time.   Is there a way to check with the IRS to see if they indeed receive my file as Exempt and if they did actually return it to my Employer? I’m just wondering if either HR forgot to follow up with me or even IF the IRS does actually cull these exempt requests in the first place? I don't have the liquidity to simply pay the IRS all at once.   What would be my best option going forward? Can spells be cast through a Wall of Force? I have a question about inheritance in Java.  I have two classes A and B , and class B, inherits from A:  public class A {      public A() {          System.out.println("Hi!");      } }   public class B extends A {      public B() {          System.out.println("Bye!");      }       public static void main(String[] args) {          B b = new B();      } }   When I run program B, the output is:  Hi! Bye!      Question : why the constructor of class A is invoked, when I create and object of class B ?    I know that B inherits everything from A - all instance or class variables, and all methods, and in this sense an object of B has all characteristics of A plus some other characteristics defined in B. However, I didn't know and didn't imagine that when I create an object of type B, the constructor of A is also invoked. So, writing this:  B b = new B();   creates Two objects - one of type B, and one of type A.  This is getting interesting,   can somebody explain why exactly this happens? It's been more than a month since I have started using . It has these users with user names in the format of "user-random number". I have observed them in some of the stack activities, most of the time asking questions.   Does the moderators create them for their own purpose. If yes what purpose do they serve?   I mean a user is free to have any user name. But it's just a hunch that such users are actually moderators. I may be wrong; just need some clarification. I am studying statistics and I am wondering when it comes to standard error or a sampling if the calculation changes when there are weights added.   I have a weighted mean:  $$\mu_{w} = \dfrac{\sum_{i=1}^Nw_ix_i}{\sum_{i=1}^Nw_i}$$ and a weighted variance calculated by:  $$s^2_{w}=\dfrac{\sum_{i=1}^Nw_i}{(\sum_{i=1}^Nw_i)^2-\sum_{i=1}^Nw_i^2}\cdot \sum_{i=1}^N(x_i-\mu)^2$$  is the sampling error still calculated as  $$\text{SE}=\sqrt{\dfrac{s^2_{w}}{n}}$$ Algorithm to detect overlapping periods
