I am having some issues with interpreting the results from a Poisson log linear model done in R. I will give my thoughts and it would be great if somebody would be kind enough to expand on it. I just need help with interpreting the coefficients.    I saw some interpretations online but almost all of use use the main effects or just one effect to explain. Also, the answers on stack exchange are not so simple that a layman could understand. Thank you in advance.   The data is from a paper titled "A Microeconometric Model of the Demand for Health Care and Health Insurance in Australia"  This is the back transformed data with intervals.    I drew some preliminary inferences,  We can infer from this that the expected number of visits by a doctor to a female at age zero is 0.23 (the intercept) with CI’s 0.195 and 0.271.  For every one extra male, the expected number of visits by a doctor increases by 0.45  with CI’s 0.349 and 0.576.  As age increases by one unit, the number of visits by a doctor increases by 1.009 for a female with CI’s 1.006 and 1.012.   Similarly, as age increases by one unit, the number of visits by a doctor if the patient is a male increases by 1.012 with CI’s 1.007 and 1.017.  Is this correct?


Add different materials to different parts of a mesh?

How do you add more than one material to a mesh?   I have tried adding two materials to the object, and then assigning one of the materials to a vertex-group, but I could not find a place to assign it.  I am making a striped bouncy ball that I want to deform, so adding a different material by separating the mesh into different objects would not be ideal.


Can I assign a virtual interface (VPN) to a 'real' interface / NIC of my choice?

I have a small server , running MINT linux with two NICS (eth0 and eth1) and I'd like to setup the MintBox as a VPN client to connect to a web-hosted VPN server.  All works wonderfully on the VPN connectivity front but I'd like to know how to 'force' the VPN to bind/assign itself to eth1, not eth0 (or any NIC of my choice).  I know that OpenVPN creates a virtual interface (tun0) but how does it 'know' which real interface to bind to / forward traffic to?  Have I understood this correctly - and if so , how is this accomplished please?


Recovering a unsaved word file after four days

I know the unsaved word documents (.asd files) are saved in C:\Users\"username"\AppData\Local\Microsoft\Office\UnsavedFiles up to four days (tested myself).

Why show joined communities count (106) for the Community ♦ moderator when the network profile shows only (1)?

I know that Community user (♦ moderator) is a background process (and not really a person). Upon visiting the "", I noticed that it has joined 106 communities (see screenshot #1 below) so far. So, out of curiosity, I clicked on the "" to see all the communities in which Community user participates. But I was surprised by the result displayed on the network profile page where it shows that it only belongs to 1 account i.e. Area 51 (Joined 5 years ago, last seen 5 years ago. -- see screenshot #2 below) I wonder why show joined communities count as 106 (as oppose to just 1) for the Community user when its network profile has only 1 account? Can anyone please explain this. Screenshot #1:    Screenshot #2:

What to do when an installer is not available for Ubuntu

If I find a program that I would like to install on Ubuntu, but there is only an installer available for Debian or another Debian derivative such as Mint, what can I do? Is there a way to use a pure Debian installer to install on Ubuntu?   I have seen some references to using dpkg or gdebi to find the right dependencies for a local copy of the installer. Is this workable solution?


Solder new RAM in a 2015 Retina MacBook Pro

Change hanging indent in description list

I'm trying to get a description's list hanging indent to lie flush with the first line of text.  I have a description list such as the following:  \begin{description}  \item[Label the first] Lorem ipsum dolor sit amet, consectetur adipisicing                         elit, sed do eiusmod tempor incididunt ut labore et                         dolore magna aliqua.  \item[The longest label] Ut enim ad minim veniam, quis nostrud exercitation                           ullamco laboris nisi ut aliquip ex ea commodo                           consequat.  \item[Shrtlbl] Duis aute irure dolor in reprehenderit in voluptate velit esse                 cillum dolore eu fugiat nulla pariatur. \end{description}   This produces the following output:    I would like to have each paragraph indented so that the following lines are flush with the first letter of the list item's text, the way it's laid out in my TeX.  For instance, the "s" of "sectetur" should be right under the "L" of "Lorem".  I've tried looking through the documentation of , but I can't seem to find a good option.  I tried specifying [leftmargin=3cm, style=sameline], but this results in the following:    This isn't quite right: I'm trying to get each item lined up differently, so that the "L" of "Lorem" is not necessarily flush with the "U" of "Ut" or the "D" of "Duis".  Does anybody know a good way to do this?

Prove by induction $\sum \frac {1}{2^n} < 1$  Well supposing the base case has been shown to be true, I start with the induction step:  Suppose true for n = k:  $$ \frac{1}{2} + \frac{1}{4} + ....\frac{1}{2^k} < 1$$  Want to show this is true for:  $$ \frac{1}{2} + \frac{1}{4} + ....\frac{1}{2^k} + \frac{1}{2^{k+1}} < 1$$  Now this is where i am getting stuck, should i be tryig to show that  $$ \frac{1}{2} + \frac{1}{4} + ....\frac{1}{2^k} + \frac{1}{2^{k+1}} < 1 +\frac{1}{2^{k+1}}$$ or should i be attempting to show that  $1 + \frac{1}{2^{k+1}} < 1$ which is utter nonsense. So i am stuck on what exactly to prove here.  Note i also thought of maybe using the geometric series of $\frac {1}{2} $ as some upper bound but then that would provide me a value that was greater than 1 so it didn't work out


Screwing power pcb to metal chassis through ground holes

I am mounting a PCB, which deals with currents up to 5A and essentially switches down 60V to 12V and 5V, on a bicycle frame. I have four holes, one at each corner, that are padded with copper traces to the ground plane. Is it ok to fix the pcb to the frame by screwing the pcb through these holes directly on the metal of the frame or can this lead to problems? Thank you for your help!


Prove that $\mathbb{Q}(\sqrt{2})$ to be the smallest field that contains $\mathbb{Q}$ and $\sqrt{2}$.

In abstract algebra we define $\mathbb{Q}(\sqrt{2})$ to be the smallest field that contains $\mathbb{Q}$ and $\sqrt{2}$. In the most of textbox they usually write that this is. $$\mathbb{Q}(\sqrt{2}) = \{a+b\sqrt{2}\mid a,b\in \mathbb{Q}\}$$ But can I prove that this is the smallest field that contains $\mathbb{Q}$ and $\sqrt{2}$.?


mysqli cannot insert and update query into mysql database

Edit: Query insert is to input new user data into the database and if the user data is already in the database before, the update query will update last_login time/date only.


Incorrect "There's" with plurals--am I missing something?

More and more lately I've been noticing--what I think of as--mistakes with plurals. I've seen this a lot in spoken English, but it's also popped up a few times in the articles and books I read. The majority of the time, this seems to be with sentences that start with "There's [...]." ie:  There's three of them on the table over there. If there's more of them in your pocket, why are you asking me? There's other ways this can go, just talk to me!  All these cases look improper to me. It should be "There are" or I guess "There're" if the speaker/writer wanted to keep the contraction. And yet, I've started seeing this multiple times on a daily basis. I've begun to question whether I'm in the wrong. Did I miss some change to the word "There's?" Can it be used for plurals despite being the contraction for "There is?" I've added the  tag in case this is a solely American quirk.

Can I refer to my own blog in a Stack Overflow answer?

I am currently building a blog in my area of expertise with a few colleagues. We hope to address answers to lots of frequently asked questions in this field. Is it appropriate/allowed to refer to our blog in a Stack Overflow answer?  I’d obviously port the relevant information across so users can see the base information to answer their question, but for deeper learning link to my blog.

I want to check if the string has multiple occurrence of a single character in a sentence and gets its length

I am new to this language and still learning, I have a windows form application that has 2 textboxes on it and a one-button, the first box is where the user input a sentence or word, the second box is where the user inputs a single character to find if it's in the sentence, the button is for counting how many multiple occurrence of a character to the sentence.  example: txtbox1: Hello World! txtbox2: o display: 2    what is the easier to do? or recommended?

Combinatorics problem with students choosing elective courses. (Prove by assuming the opposite).

There are 2009 different elective courses in the university. Each one of the courses has exactly 45 students in it. Every 2 courses has exactly 1 student in common. Prove that there is a student enrolled in all courses. I think it should be proven by assuming the opposite. Maybe there is a connection that 2009/45 is less than 45 but I'm not sure about that.


I am stuck in the following problem:  Show that every group of order 4 is an extension of $\mathbb{Z}_{2}$ by $\mathbb{Z}_{2}$. Which of the exact sequences splits?  Ok, i have to consider two cases for a group of order 4: $\mathbb{Z}_{4}$ and $\mathbb{Z}_{2}\times \mathbb{Z}_{2}$, so i get two exact sequences:  $0\rightarrow \mathbb{Z}_{2}\overset{\psi }{\rightarrow}\mathbb{Z}_{4}\overset{\varphi }{\rightarrow}\mathbb{Z}_{2}\rightarrow 0$  and $0\rightarrow \mathbb{Z}_{2}\overset{\tilde{\psi} }{\rightarrow}\mathbb{Z}_{2}\times \mathbb{Z}_{2}\overset{\tilde{\varphi} }{\rightarrow}\mathbb{Z}_{2}\rightarrow 0$  For both cases i checked the conditions of exact sequence and proved that these are exact sequences. Now i have a problem how to show if they split or not.  We say that an exact sequence splits if for the first sequence there exists a group homomorphism $\pi :\mathbb{Z}_{2}\rightarrow \mathbb{Z}_{4}$ with $\varphi \circ \pi =id_{\mathbb{Z}_{2}}$ and for the second $\tilde{\varphi} \circ \tilde{\pi} =id_{\mathbb{Z}_{2}}$, right? But how to show if these group homomorphisms exist or not?  Can anybody help me, please? I would appreciate any hints and comments. Thank you in advance!


Multiple choice exercise on $f(x)= \frac {\sin x}{|x|+ \cos x}$

Let $f : \Bbb R \to \Bbb R$ be the function defined by $f(x)= \frac {\sin x}{|x|+ \cos x}$. Then A.$f$ is differentiable at all $x \in \Bbb R$. B.$f$ is not differentiable at $x =0$. C.$f$ is differentiable at $x=0$ but $f'$ is not continuous at $x=0$. D.$f$ is not differentiable at $x=\frac {\pi}{2}$.  Using the standard definition of derivative, I get that $f$ is differentiable at $0$ as well as $\frac {\pi}2$. This is as follows, $\lim_{h \to 0} \frac {f(0+h)-f(0)}{h}=1=\lim_{h \to 0} \frac {f(0-h)-f(0)}{-h}$ and $\lim_{h\to 0} \frac {f(\frac {\pi}2 +h)-f(\frac {\pi}{2})}{h}=0=\lim_{h \to 0} \frac {f(\frac {\pi}2 -h)-f(\frac {\pi}2)}{-h}$ using L'Hospital rule at one stage. Hence I eliminate options B and D. Since $0$ was the only doubtful point to check about differentiability, I choose option A as the answer. I regret a little about not knowing how to check validity of option C. Can you tell me how to prove it wrong?


Conjugating verbs for nouns referring to groups of people

Possible Duplicate:          Frequently when reading tech articles, I see sentences like "Microsoft have released ..." or "Apple have announced ...". This seems wrong to me because the nouns are singular; Microsoft and Apple are individual companies, even though they refer to groups of people. I have not seen this usage outside of tech journalism, but it's pervasive enough that it makes me wonder: is this actually the correct usage?  As a follow-up question, is it correct to use a plural pronoun for a singular antecedent like this? For example, "Apple has announced they are changing their name to Orange" or "Apple has announced it is changing its name to Orange". The second form seems technically correct but sounds awkward.

Show there is a surjective homomorphism from $\mathbb{Z}\ast\mathbb{Z}$ onto $C_2\ast C_3$, where $\ast$ denotes the coproduct in the category $\mathsf{Grp}$.   Note the exercise in this book (Algebra Chapter 0, Aluffi) is meant, or at least hinted at, to be done using the universal property of the coproduct, ie: coproduct of $A$ and $B$ in $\mathsf{Grp}$ is initial in the category $\mathsf{Grp}^{A,B}$, instead of using the definition of the free product.  By property of the coproduct, for any object $A$ and two homomorphisms $f_1,f_2:\mathbb{Z}\to A$, and two homomorphisms $i_1,i_2:\mathbb{Z}\to\mathbb{Z}\ast\mathbb{Z}$, there exists a unique homomorphism $\sigma:\mathbb{Z}\ast\mathbb{Z}\to A$  such that the diagram commutes, ie: $f_1=\sigma i_1$ and $f_2=\sigma i_2$. Now let $A=C_2\ast C_3$. Now what?

Gandalf - open displays of power versus his restrictions as an Istar

Throughout both the Hobbit and Lord of the Rings (and I need to stress that I'm talking about the books, not the movies) we see Gandalf quite liberally tossing magic about.   He uses lightning in his battles with the Nazgul (on Weathertop) and the Balrog (in and above Moria). He regularly ignites fires. He casts light from his staff. He uses spells to (attempt to) open doors, to close doors (even bragging about how many of the former he knows). He speaks "words of command". He casts shafts of white light at flying Nazgul.   And many more examples.  Yet, as a member of the Istari he is supposed to be restricted from using power.  He is supposed to inspire, encourage, and get results primarily through the actions of other people.  Now, I consider myself quite well-read in my Tolkien, but I'm having some difficulty reconciling the two.  What's going on there, then?  Answers I'm looking for would include sourced quotes that need not go so far as to explain this exactly, but at least support it's plausability.

Intersection of a family of non-empty closed intervals

I've been trying to make sense of this in my head. I know that the nested interval theorem proves the following if the intervals are bounded, but what if they are unbounded? I apologize for my ignorance to type mathematical symbols on this editor.  Let I be a family of non-empty closed intervals, and suppose that I has the finite intersection property.

What should you do if you don't hear anything back from editor after a whole year from first submission?

I have submitted a paper more than a year ago, but still I haven't heard anything back from the editor. As of today I have no idea whether my paper has been accepted/rejected or is in a review stage. Only thing I know is that it has been received, for a got a confirmation of this soon after the submission. Needless to say that I've tried several times to get in contact with the editor to find out about my paper's fate, but I got not a single reply to my status update requests. What should you do in a case like this? I was thinking of writing to the editor again to let him know that I'm withdrawing the paper from him and submitting to someone else? Is this a good idea? Are there other paths one might walk down to?


Undelete utility that preserves folder structure

I did a dumb thing and now need to undelete some files.  In fact, I have already recovered the files using , which has served me well on the other rare occasions where this has been necessary.  So I have the files.    The problem is that Glary and the  don't preserve the original folder structure.  In this case I have about 3,000 small files that I must match to their original locations in a complex nested folder hierarchy.  I could see the full folder paths in Glary before the restore, so I know the information is there; it's just not using that information and copying everything to root of my designated destination, rather than relative to the original location.


Limit superior does not increase when a sequence is replaced by its sequence of averages

Let $\{x_n\}$ be a bounded sequence of real numbers, and define a new sequence $\{\sigma_n\}$ by $$\sigma_n=\frac 1n\sum_{i=1}^nx_i.$$ Prove that $\limsup \sigma_n\le \limsup x_n$.  I am confused on how to attempt this problem. I don't see how the $\limsup x_n$ is greater then the arithmetic average of the $x_i$'s.


I want to check the given right hand side equation is equal to the left hand side or not. The value of $x = (19/30). (((6*($x)) - 5)/(7 - (3*($x)))) = ((4 - (8 * $x))/((4 * $x) + 2)) I had tried below mentioned code, but it shown the RHS value is greater than LHS. <?php  function check($m, $n)  {           $rhs = abs($m);      $lhs = abs($n);      if($rhs > $lhs){          echo "$m is greater than $n";      }     elseif($rhs < $lhs) {         echo "$m is smaller than $n";      }     else{         echo "$m is equal $n";     }  }    // $m = ((6*(19/30)) - 5)/(7 - (3*(19/30))); // $n = (4 - (8 * (19/30)))/((4 * (19/30)) + 2);   $x = 19/30; $m = abs(((6*($x)) - 5)/(7 - (3*($x)))); $n = abs((4 - (8 * $x))/((4 * $x) + 2));  check($m, $n);   ?>  The output: 0.23529411764706 is greater than 0.23529411764706


Updating packages when network access to standard repositories is blocked

My college just blocked Ubuntu repositories. So is there any way to install texlive package from something like zip?

How to press any char by javascript (not by keyboard)

I want to press char by java script instead of keyboard (just for my education). I have input and I want to press key inside it, but it doesn't work (I know that initKeyboardEvent is only in Chrome, I use Chrome), what is wrong in this code?  <input id="edit"> <script>     var inp = document.getElementById('edit');     inp.focus();      var ev = document.createEvent('KeyboardEvent');      ev.initKeyboardEvent(         'keypress', true, true, window, false, false, false, false, 49, 0);      document.body.dispatchEvent(ev); </script>


The use of the Axiom of Choice in this proof of the sequence lemma

Here is a proof of the sequence lemma I lifted from this . It seems to me naively that the axiom of choice is being used to selected the $x_n$'s. Is the axiom of choice being invoked in this argument? Is it necessary?  The top answer in this  says that we can choose some element from each set in a finite collection of non-empty subsets without choice, though I'm not sure how to do that rigorously. Could some inductive argument be used in the case above?


Setting an admin user via the GUI - command line equivalent?

To designate a user as an administrator from the GUI, you can simply open-up that user's properties and select the Account type as the "Administrator" option.    If the user already exists, what effect does selecting this account type have at the system level?  (added to sudo group, modification to /etc/passwd or /etc/sudoers...etc)  And how would I accomplish this (designating a user as an "Administrator") from the command line?

Ubuntu Core Raspberry Pi 3 Image not working on Raspberry Pi 3 B+

Is there an Ubuntu Core image for the Ubuntu Core on Raspberry Pi 3 B+?  When I use ubuntu-core-16-pi3.img.xz on my Raspberry Pi 3 B+, the red LED lights up solid, and I see the rainbow screen.  I have tested the image, and it works on my Raspberry Pi 3.  I've also tested NOOBS v2.9.2 "Raspberry Pi Desktop, Debian" on the Raspberry Pi 3 B+, so I'm confident that that device is at least functioning.


Control the colours of shapefiles loaded to Geoserver?

I have a set of shapefiles loaded to GeoServer, which I later deliver as a WMS. All the shape files are rendered in the same neutral grey, which makes it quite difficult to tell apart which shape file I'm visualizing. Can I assign colours of textures to each polygon? A very similar question was posted earlier. But, since the user relied on ESRI technology, all answers focused on ESRI solutions; not GeoServer.  The question linked to mark mine as duplicate is a different question; even if both answers happen to be in the same manual. I want to give a colour to each shapefile. While the other question was about assigning colours based on the value of a field.


I'm actually in a course of Abstract Algebra, and the teacher asked some interesting questions at the end of a course on the material we had seen. I found the answer to the first question, but the other two leave me perplexed. Could you give me your opinion on the questions (2) and (3)?  (1) Is the function $f : \mathbb{N} \to \mathbb{N} $ such that $$f= \begin{pmatrix} 1 & 2 & 3 & 4 & ...\\ f(1) & f(2) & f(3) & f(4) & ... \end{pmatrix} = \begin{pmatrix} 1 & 2 & 3 & 4 & ...\\ 2 & 3 & 4 & 5 & ... \end{pmatrix}$$ is a permutation? Answer : no, because $1$ isn't an element in the image.  (2) Is there a function $ f \in S_E$  that is factorisable into disjoint cycle of infinite order such that $\mid \{n \in \mathbb{N} : f(n) \not= n\}\mid < \infty$ ?  Definitions :    $S_E$ is the set of all permutation of E.  Let the set $E \not= \emptyset$. W say that a map $f : E \to E$ has an inverse function, if there is a mapping $g : E \to E$ such that both composition $f \circ g$ and $g \circ f$ are the application identity for each $x$ element of $E$. We say that $f$ is a permutation (bijection) of $E$ .    (3) Does the subset of functions $\in S_{\mathbb{N}}$ ($S_E$ with $E=\mathbb{N}$) consistent with $\mid \{n \in \mathbb{N} : f(n) \not= n\}\mid < \infty$ form a group?

prm0009.dll cannot be repaired sfc /scannow

My Windows 10 Pro has recently started blue screening about once or twice a week. I would try some tweaks from google searches of the BSODs, at least 6 different ones, that people had said worked.  I did a "fresh" install, meaning I updated from 8.1 to 10 then ran Windows Reset. This was approximately 2 months ago after my SSD (which was found to be healthy) decided it didn't want to boot.  Today however it has crashed four times so far. So I ran the SFC /scannow utility and it found one un-repairable dll called "prm0009.dll". It resides within the %windir%\WinSxSfolder. In particular, the folder is named  C:\Windows\WinSxS\amd64_microsoft-windows-wordbreaker7-english_31bf3856ad364e35_10.0.14393.0_none_74c5ad926cf35d8d\prm0009.dll  I have spent the past hour trying to google what it is for and where it came from and where I can get a replacement version. I searched my entire C:\ to see if another one existed but this is the only instance of the file.  Here is a link to the sfcdetails.txt file that I generated from the cbs.log file:   Any help would be greatly appreciated.

I have a difficulty with understanding Hawking radiation. So far, I have "understood" (I can be wrong!), that the intense gravity of a black hole can split pairs of virtual particles so that one escapes the black hole, while one is absorbed (is that accurate?).   In QFT terms, I am assuming that this means gravity somehow splits the fields present in the vacuum, from which I'm concluding that we would have many types of particles in Hawking radiation, not just photons: is that accurate, or is it nonsense because the gravitational field doesn't interact with the other fields?  Note: my exposure to QFT is rudimentary, mostly focused on the EM field.

Steam games by sneakernet with an external hard drive - Is it possible? if so, how can I do it?

I've recently moved houses, but unfortunately my new place is in a part of town where the only economical way to get an internet connection is via a prepaid data modem (DSL in my building is super expensive for a super slow speed) and as such large downloads aren't really possible unless I pay about $12 in local currency for every 15 gigs of prepaid data - not really an option.  I have two computers, a laptop and a desktop, both running steam, and my family doens't mind if i leave the laptop around their place to download large files (they live in a different part of town with MUCH faster internet). I was wondering if it's feasible for me to download games onto an external hard drive by bringing my laptop over there, then installing them or transferring them onto my desktop PC over at my new place. I know it's possible to copy steam games over to an external hard drive, but i'm concerned that downloading the game using a different computer than the one that'll actually run it might cause issues. Both computers are running 64-bit Windows 10.

Dropping insignificant interaction term makes insignificant main effect significant: what do?

I have a mixed effects model with one random effect and two fixed effects, both of which are of interest. There is some reason to believe that there would be an interaction between these two fixed effects.  When I run the model with both main effects and their interaction, none of them are significant. If I take out the interaction term (which I probably shouldn't have done, but I did out of curiosity), one of the effects becomes (very) significant, in a way that would be of considerable interest. It seems to me that I should go with the model with the interaction in it, but I am concerned that I am missing the effect of the variable that becomes very significant once the interaction is removed.   Should I include the interaction in the model? If I haven't provided enough information here for someone else to give accurate advice, what should I consider in order to make this decision?  (Also this is my first question, so apologies if I have asked it poorly)


Create new Instance of Object with Interface

I got one Interface and one Class.  public interface IUser{     public String getFirstname();     public String getLastname(); }  public class User implements Iuser{     String firstname;     String lastname;      public User(String firstname, String lastname)     {         this.firstname = firstname;         this.lastname = lastname;     }      public String getFirstname(){         return firstname;     }      public String getLastname(){         return lastname;     } }   When I usually need to create an instance of an User I would do:  User user = new User("Mike", "L");   But I am confused with articles that I found on the internet, because they are creating an instance of an User-object like this:  IUser user = new User("Mike", "L");   I would like to know why programmers are creating an User instance with the Interface in front of it?  What is the reason of creating an instance in this way?  Why would you prefer IUser user = new User() instead of User user = new User()?


Idempotent elements on the quotient ring

I am trying to prove the following result:     If $R$ is a commutative ring with identity, $I$ is an ideal of $R$ such that $I^2=\{0\}$ and $a+I$ is an idempotent element in $R/I$ then there are some idempotent element of $R$ in the coset $a+I$.   What I tried to do?  Well, suppose that $a+I$ is idempotent in $R/I$, then $(a+I)(a+I)=a+I$, so, $a^2+I=a+I$ and then $a^2-a \in I$. We know also that $1-a+I$ is idempotent since $(1-a+I)(1-a+I)=1-2a+a^2+I = 1-2a+a+I=1-a+I$. And then, from this we know that $a(1-a)+I$ is idempotent.  We need to show that there exist some $m \in I$ such that $(a+m)^2=a+m$, but $(a+m)^2=a^2+2am+m^2=a^2+2am$ since $m^2=0$, so $m$ needs to satysfy $a^2+(2m-1)a-m=0.$  I dont know if this reasoning is right, neither if this is a way to go over it. Can someone give me a hint to finish it?


How do I prevent the “Super” button from opening Activities?

Why does everyone seem to assume that gravitational waves will always be very small?

The size or effective distortion field of a gravitational-wave perturbation at any given location in space-time is determined by the distance separating the source and that location. This describes a gradient of gravitational-wave intensity that ranges from the minuscule to the macroscopic. So, a confluence of gravitational sources sufficiently large within the Milky Way galaxy for example or within 1000 ly of the earth will yield a much larger gravity wave, a wave that may even cause damage. So why does no one speak of this?


Preview refuses to open pdf file, incorrectly claiming a permission issue

I had to force-quit Preview (it became unresponsive after trying to open a 200Mb animated gif), but after re-starting it, some files that were open before no longer open. Instead an error box pops up saying that      The file “file.pdf” couldn’t be opened because you don’t have   permission to view it.   and      To view or change permissions, select the item in the Finder and   choose File > Get Info.   (how can I generate an image of that error box?).  However, the file permissions are okay, finder generated the usual preview, and acroread can open the file. I suspect that Preview has generated some lock for this file somewhere, but I'm not sure where and how. OSX 10.9.5. (copying the file in a terminal to another one and trying to open that didn't help, as did changing permissions to read-write for everyone).


I am setting a "formula book" to gather my formulas I need during exams.

I was not able to find a definition how to do define that permanently.  Is there any way to set the \normalsize to the size of \footnotesize or define \footnotesize as default?

$$x+y+z=3$$ $$x^3+y^3+z^3=15$$ $$x^5+y^5+z^5=83$$ I spent around 3 hours in solving this equation, but, finally I didn't do it so, I hope you can help me in approaching this problem.


How to calculate a sample size for validating correct/incorrectness of records in a data table?

I have read through existing answers on CrossValidated (plus elsewhere online) and can't find what I'm looking for, but do please point me to existing sources if I've missed them.  Let's say I have a data set of N=1000 records, each of which can be manually sampled and labelled as either 'Valid' or 'Invalid' (or True/False, Right/Wrong, etc).    I want to achieve a given level of confidence that all records in the data set are Valid.  As I sample records, if I find a single Invalid one I would go back and amend how the data set is created to rectify that and similar problems.    So, after some iterations of spotting Invalids, fixing and recreating the data set, I do some sampling that only includes Valid records.  If I want to be (say) 99% or 95% sure that all records are Valid, how big does my sample have to be? (Ideally as a function of N.)  I've tried playing around with Hypergeometric tests () - in that context I want to know what k should be, but I don't have a fixed value of K. Rather I want to choose k such that K is likely to be equal to N - but setting K=N obviously works out to a Probability of 1! I'm also wondering if I need to use a Bayesian approach but I don't understand Bayesian stats enough.

Are there any differences between insmod and modprobe?


How do I change the location of macOS screen captures?

As a developer, I take a lot of screen captures. I often take screen shots to share with Stack Exchange members in chat.  The problem is my Desktop is so cluttered with screen captures that they're now overlapping! I'd like to save all screenshots in a dedicated folder or directory.  In macOS, how do I change the default location where screen captures are saved?  These are the screen shots taken with CommandShift3 or CommandShift4 keyboard shortcuts.  I would prefer a solution which doesn't require installing any software.


Crucial BX100 SSD installation in an Asus Q550LF

I just purchased a  SSD to install in my . The system BIOS is at version 211. I made sure that the drive was   with my machine prior to the purchase. I installed the new SSD, I can see the SSD in BIOS, but when I try to install Windows 8.1 (via DVD), it says that the system cannot find a drive to install to. It then prompts me to install drivers of some sort.   My next step right now is to connect it to a SATA to USB cable to see if I can make in progress there, but any ideas or input would be greatly appreciated.  Am I doing anything incorrectly?  UPDATE:  I went to the article that was marked as a duplicate, the solution did not work. I see no disk when I go to list my disk. My situation is different, making this question a 'non - duplicate' question.  I reached out to Crucials customer service, they don't have any idea either as to why it's not working.   I will be flashing my BIOS to see if that lets me see my drive. If not, I'll be returning the drive.  FINAL UPDATE:  It ended up being that my BIOS needed to be flashed. I flashed it to 215. The installation would NOT let me use a GPT partition on the SSD. I followed  to partition the SSD to MBR. I am unsure as how to mark my own question as an answer, maybe I can't since I don't have enough rep.


Is the Star Wars Universe just one galaxy?

At the start of the movie it says:      "A long time ago in a galaxy far, far away...."   Does this mean that the entire Star Wars saga takes place in a single galaxy? To my understanding a galaxy isn't very big compared to the universe itself. Star Wars has many different sentient races, and the way they are presented suggests that most planets are host to only one of them (some exceptions like naboo). This strongly leads me to believe there should actually be more galaxies in the Star Wars universe (hehe).   Another thing, I think it's safe to assume that even if the entire saga takes place in one single galaxy, their researchers can observe other galaxies (I think we started doing that in the 1600s, and they are a lot more technologically advanced than we were back then). When Obi-wan is looking for Kamino (the rain planet with the cloners) the librarian says something like "If it's not in our records, it doesn't exist", so she must be convinced that the entire universe has been explored.    If the entire universe has been documented, why wouldn't they go to those other galaxies? The technology seems to be advanced enough to hop to another galaxy. Is there any canon material that suggest that traveling between galaxies is done? If not, is there a canon explanation why they don't?


Transparent background but solid title bar and text in Windows 7

I'd like to have a terminal like the one in Ubuntu where the background is transparent but title bar and text is still solid. I have tried Console, but setting the alpha value makes the entire window transparent, which makes the text hard to see.  Is that possible?

Name for “having no concern about the truthfulness of one’s own remarks”

Take the following statement:     I hate the ease with which X makes disparaging remarks about their rivals without the least concern as to whether they are truthful or fair.   Now I would like a word expressing this lack of concern, so that I could just plug it in the blank below and keep the meaning of the sentence above:     I hate the _________ with which X makes disparaging remarks about their rivals.   This is an all too common attitude and I think it deserves a name of its own. The word that came to my mind was levity, but I haven’t come across this word very often and I’m not sure of its particular tones and shades of meaning.      Simple definition   : a lack of seriousness   : an amusing quality   Full definition   1 : excessive or unseemly frivolity   2 : lack of steadiness: changeableness     The attitude I’m trying to name certainly displays lack of seriousness as to the truthfulness and fairness of the remarks, but I do not want to imply they are made in jest or that X is being silly or thoughtless. X could be very serious about their aims: “I’m going to say this; don’t give a dam whether that’s true or not; even if it’s not true I’ll get away with it.” This excludes, I think, all the words Merriam-Webster lists as related to levity, which probably means it excludes levity too:     facetiousness, flightiness, flippancy, frivolousness, frothiness, frivolity, light-headedness, light-mindedness, lightness, silliness   So I’ll accept an answer that despite my reservations shows that one of these words is indeed the one that works best in the sentence above; or gives a more fitting word; or shows that no word really fits (I am of course aware of the difficulties of proving a negative).  I prefer a single word but I’m willing to trade singleness for meaning: so I would take a short phrase it fits better than any single word.  Update  I’m spoilt for choice. But I wonder whether the various suggestions implying lack of concern would in my sentence imply lack of concern specifically for truth, which is what I’m after, or could instead be interpreted as lack of regard for norms of polite behaviour, rival’s feelings, or consequences (say, libel lawsuits, rivals reacting with violence, people feeling encouraged to attack the rivals, etc.)  Tweak the example sentence if it helps (say, I hate the ____ of X’s remarks).


Testing for a minimum amount of items in a players inventory

I am attempting to make a shop in which you can trade a number of items for coins (ender stars).    I'm using the /testfor command to see if they're on the right team and /clear to remove the items, however, when someone presses the button with only one item their one item is removed and they get the coin even though the shop requires you to pay 5 items.    How do I make it so it tests to see if they have the minimum amount of items in their inventory before it clears the item and gives them the coin?


What does the first colon-separated number in a Debian/APT package version number like 1:2.10.1-4 mean?

Let's take a look at the amavisd-new package:  # apt-cache policy amavisd-new amavisd-new:   Installed: 1:2.10.1-4   Candidate: 1:2.10.1-4   Version table:  *** 1:2.10.1-4 500  ...   The command returns 1:2.10.1-4 as though the actual amavisd-new version is 2.10.1-4. What does the proceeding 1: mean in front of the actual version number?

Why are neural networks becoming deeper, but not wider?

In recent years, convolutional neural networks (or perhaps deep neural networks in general) have become deeper and deeper, with state-of-the-art networks going from 7 layers () to 1000 layers ( in the space of 4 years. The reason behind the boost in performance from a deeper network, is that a more complex, non-linear function can be learned. Given sufficient training data, this enables the networks to more easily discriminate between different classes.  However, the trend seems to not have followed with the number of parameters in each layer. For example, the number of feature maps in the convolutional layers, or the number of nodes in the fully-connected layers, has remained roughly the same and is still relatively small in magnitude, despite the large increase in the number of layers. From my intuition though, it would seem that increasing the number of parameters per layer would give each layer a richer source of data from which to learn its non-linear function; but this idea seems to have been overlooked in favour of simply adding more layers, each with a small number of parameters.  So whilst networks have become "deeper", they have not become "wider". Why is this?

I have a class lets say myFrame that extends JFrame. On this frame I have a button with a action listener event. When this event triggers I want to make changes to the class(myFrame) like I would have done in the constructor of the class using this.add() or whatever function I need.   The problem is that if I use "this" in this action listener I am no longer referring to the current instance of the class myFrame. I vaguely remember that I have come across this issue before but I cannot remember how I went around it. I think I might have assigned this to some variable in the constructor of the class.

Show that $q\equiv_8 1$ when $q$ is an odd square number

Problem: Given: q is an odd squared number - show that: $q\equiv_8 1$  My assumption: $\forall q\in N:\exists a \in Z: a =1\pmod{2}$ and $a^2=q$.  Then I tried to show that it's only true satisfyingly if $\mathrm{gcd}(q,8)\mid 1 \leftrightarrow x\cdot q+y\cdot 8=1$.  But I don't know how to show that it is true for all numbers $q$.  All hints are welcome.


How can I pass an environment variable through an ssh command?

How can I pass a value into an ssh command, such that the environment that is started on the host machine starts with a certain environment variable set to my choosing?  EDIT: The goal is to pass the current kde desktop ( from dcop kwin KWinInterface currentDesktop ) to the new shell created so that I can pass back an nfs locations to my  instance on the original server which is unique for each KDE desktop. ( Using a mechanism like /)  The reason multiples ssh instances can be in flight at one time is because when I'm setting up my environment, I'm opening a bunch of different ssh instances to different machines.


Can I legally remove the default Unity splash screen by removing it from the APK?

While using Unity I export an Android game as an APK. When the APK is run, the first thing that is displayed is the Unity splash screen. I worked out that I could replaced that image by opening the APK like a zip file, looking for the splash screen image  (App.apk/assests/bin/Data/splash.png) and replacing it with any image I wanted.  Is it legal to publish Unity-powered Android game apps with modified splash screens like this? I remember that some games on PS3, 360 and Wii have been created with Unity but don't display a Unity splash screen when run on their respective consoles.

Find the sub-sequential limits of a recursive sequence

Given $a_1 \in \mathbb R$ . Consider the   sequence  $\{a_n\}$, which is recursively  defined by$$ a_{n+1} =\left\{\begin{array}{ccc}   \dfrac {a_n}{2} &  \text{if $n$ is even,}\\  \dfrac {1 + a_n }{2} &  \text{if $n$ is odd}.\end{array} \right. $$  Find the sub-sequential limit of this sequence.  I think  for  odd  $n$  the  limit  point will be   $l= \frac{1+l}{2}$ now  $2l = 1+l$  , here $ l = 1$  I don't  know the  limit point for0 even  $n$.  Please help me.


What is and is not "personality" for the purpose of Polymorph?

It's well understood that "___ Polymorph" spells overwrite pretty much everything in a stat block (or character sheet) with numerical functionality, including languages, proficiencies, and named features. Everything except "alignment and personality".  What does "personality" mean? A very inclusive option would be "any knowledge or memory that doesn't have a predefined quantified effect". A very exclusive option would be "personality traits, flaws, bonds, & ideals exactly as written, plus relationships & emotions, but otherwise tabula rasa as befitting a creature who just sprang into existence".  As pointed out, "" is indeed a similar question, so I'll refocus this one.  Is there rules evidence that the original creature's knowledge and memories are retained after a Polymorph, other than emotional responses about people/places/objects/actions they like or dislike (aka "personality")?   Let's look at this example creature :   Pre-Polymorph Bob ("PRE") was an AL-legal medium-sized humanoid PC with 10 Intelligence, proficient in History, Nature, Performance, Violin, Thieves Tools, Common, Halfling, all Armor, Simple and Martial Weapons, able to cast Sorcerer spells up to 3rd level. True Polymorphed Bob ("POST") is a medium-sized non-humanoid creature that includes the complete humanoid body plan (possibly plus wings, a tail, or other bonus parts) with 10 Intelligence, proficient in Stealth, Perception, Tinkers Tools, Common, Gnomish, Light Armor, Simple Weapons, no spellcasting.    Unlike Feeblemind or Modify Memory (the examples in the prior question's answer), Polymorph changes the creatures proficiencies. Obviously, POST is not proficient at the Charisma (Performance) or Dexterity (Violin) checks needed to put on a show or play a particularly difficult piece. But more importantly, POST also is not proficient at Intelligence (Performance) or Intelligence (Violin) checks to answer informational questions about the process of a violin performance. POST is no better at this task than an average Commoner. POST is missing some portion of PRE's knowledge. Furthermore, POST has gained knowledge (languages, skills, tools) that PRE never possessed.  If we need to use  to say that somehow Bob can lose and gain proficiencies without any change to their memories, then okay, I'll accept that, but I'd like to have rules justification for it. Otherwise it makes more sense to me that POST is actually a completely new being that's strongly influenced by the presence of PRE's "soul".   is somewhat helpful, but Jeremy Crawford only talks about "identity" and "core personality" in terms of caring about your friends, likes vs dislikes, and other emotional responses. Unfortunately he doesn't discuss memories and factual knowledge.     Pre-Bob: Hello, I'm Bob the violinist!      Alice: Oh? What do you like about violins?      Pre-Bob: Wow, let me tell you, there are so many things... blah blah blah...      (15 minutes later)      Alice: Sheesh, stop already! TRUE POLYMORPH!      (POP)      Post-Bob: I'm still Bob the violinist!      Alice: Oh? What do you like about violins?      Post-Bob: ... I don't know. I just like them, okay?


How to do logistic regression subset selection?

I am fitting a binomial family glm in R, and I have a whole troupe of explanatory variables, and I need to find the best (R-squared as a measure is fine). Short of writing a script to loop through random different combinations of the explanatory variables and then recording which performs the best, I really don't know what to do. And the leaps function from package  does not seem to do logistic regression.  Any help or suggestions would be greatly appreciated.


I've read a few post on fetch vs pull. I get that to push to the remote you need to fetch. I also understand that if you need to checkout a branch that was added to the remote you need to fetch from the remote to update your local tracking branches. My question is why wouldn't I simply just to a pull? Why do most developers suggest doing a fetch instead? In what circumstance are you just doing a fetch? Draw a scenario for me.

Troubles Switching From Natbib to Biblatex

Where have I gone wrong?  (I should mention that I use Mendeley to manage my references, and so my external bibliography file has to be a .bib file, since this is what Mendeley outputs)  Here are the error messages I got:


Does the base-10 (decimal) system have a natural advantage over other bases?

Note: This question arguably spans mathematics and linguistics, and possibly other disciplines, but I am posting it here because I think that mathematicians are best placed to answer it.    The base-10 (decimal) number system is the most common symbolic counting system used by people today.  Scholarly literature on number systems state that this is derived from the use of fingers in the representation of numbers (see e.g., , p. 1-2).  However, there are also cases of , up to base-20.  It seems evident from this history that humans can handle number systems with various bases.  The use of binary numbers in electronic computing occurs because it is efficient to manufacture components that exist in a binary state.  This suggests that the most efficient base is the smallest base, which is the binary system.  Since this is (arguably) the most efficient system for electronic computation, it is arguably desirable for humans to be able to easily and rapidly convert between their own common number system, and the binary system.  This suggests that it would be more efficient for humans to adopt a number system that is base-2$^k$ for some $k  \in \mathbb{N}$.  The obvious choices, operating within an appropriate range of symbols and digits, are the octal system (base-8) or the hexadecimal system (base-16).  These  systems can be trivially converted back and forth with binary numbers, since they merely require the user to know the binary representation of each base element, and string numbers together with the place method.  Question: Aside from its derivation from finger counting, is there any property of the base-10 number system that gives it a natural advantage over other bases for human use?  What are the pros and cons of adopting a base-2$^k$ number system (e.g., base-8 or base-16) in place of the presently common decimal system?  Would conversion to one of these systems be desirable?


I have two paths:  \\10.11.11.130\FileServer\Folder2\Folder3\ \\10.11.11.130\d$\Main\FileServer\Folder2\Folder3\   And I want to detect if the both paths are the same.  I want it because I'm trying to move one file to another directory. So for the paths above, an exception is thrown.  I know I can use try and catch, but there is another way?  I thought about removing d$\Main from the second path and then compare, but it's not always true..  Any help appreciated!


I have a variable defined in one class, let's say class A:  private char[,] matrix;   Later in my code, this matrix is initialized and populated according to some conditions.  Now from another different class, let's say class B, I need to get the final matrix.  So I have two options:   Implement a public property in class A that will be accessed from class B:  public char[,] GetMatrix  {    get    {       if (this.matrix == null || this.matrix.Length == 0)      {         // Matrix is null or it has no elements on it.         return null;      }      else      {         return this.matrix;      }   } }  Implement a public method in class A that will be accessed from class B:     public char[,] GetMatrix()      {            if (this.matrix == null || this.matrix.Length == 0)          {             // Matrix is null or it has no elements on it.             return null;          }          else          {             return this.matrix;          }     }    As stated  it is recommended to use a method in case the operation returns an array.  Also it is said:     Use a method where the operation returns an array because to preserve the internal array, you would have to return a deep copy of the array, not a reference to the array used by the property. This fact, combined with the fact that developers use properties as though they were fields, can lead to very inefficient code   So in my case, which option is the best? and why?


Generate 3d surface plot using black and white heightmap and pgfplots

I am searching for the best way, software or script (latex, python, R, octave), to interactively draw or paint some 3D surface plot for pedagogic usage.  I finally found a way to generate and transform pdf 3D surface plot with svg export using pgfplots latex package. Thus I can redraw/rework initial drawing to render a graphic like this.    But I don't want to use a common mathematic function for input of the 3d drawing, I want to use, if possible, a heightmap to generate the surface.    Is it possible to transform a random black and white heightmap into a 3Dsurface plot with pgfplots ?


Because of its length, the two towers of the Verrazano Bridge are not parallel: they are [???], accounting for the curvature of the earth.  There's a bunch of terms that come close, such as:     Radial from the center of the earth.   Okay, but this only covers vertical lines.     They're skewed.   Close, but no cigar. "These two lines are skewed." Huh?  Is there an exact term?

Problem with $\int_{0}^{\infty} \frac{\log^2(x)}{1+x^2}$ (by residues)

I, I am trying solve the following integral $$\int_{0}^{\infty} \frac{\log^2(x)}{1+x^2}$$  Teachers teached me that I can solve the integral $$\int_{0}^{\infty} \frac{\log^2(x)}{1+x^2}=\frac{d^2}{d\lambda^2} \int_{0}^{\infty} \frac{x^{\lambda}}{1+x^2}$$  I get to the second integral that  $$ \int_{0}^{\infty} \frac{x^{\lambda}}{1+x^2}=\frac{2\pi i}{1-e^{2\pi i \lambda}}sin\left(\lambda \frac{\pi}{2}\right)=\frac{-\pi}{e^{\pi i \lambda}sin(\pi\lambda)}\sin\left(\lambda \frac{\pi}{2}\right)$$  so when I try derivate I can get a exist solution because when $\lambda=0$ then $sin(\lambda \pi)=0$  I have to solve the integral by residue methods, with the formula


Upgraded to 20.04. Much software is now snaps. I installed both FreeCAD and GnuCash as snaps from the software center, and neither has created a .desktop launcher that can be found, launched, or added to favorites in GNOME.   I know I could make them by hand, but am I doing something wrong? I removed the snaps and installed via apt, and the .desktop launchers are now present. Shouldn't snaps also create .desktop launchers?

How to create native binaries for your Java app?

I'm wondering how to package a Java application into a native binary for Windows, Linux and Mac OS X.   I know Minecraft does this, but I can't figure out how. This is what'd I'd like to do:   From NetBeans (preferably) or Eclipse, build the three binaries automatically. Include native libraries for OpenGL et. all. Obfuscate my code if possible.   If there's some way to mimic the Minecraft auto-updater feature, that'd be totally awesome.  So, are there any tools available to do this for you, or do I need to write a large bulk of XML to accomplish this?

How do I calculate   $$u(w)=\int_0^\infty \frac{1-\cos(wt)}{t}\,e^{-t}\,dt$$  I tried to do it, I use partial integration but I get lost. Is there any nice simple way to calculate it?


How are passwords to listen in on the magical radio show "Potterwatch" protected?

In The Deathly Hallows (chapter 22 of the same name), Harry, Ron and Hermione manage to listen in on the Potterwatch radio show which is being sent from a secret location by anonymous radio hosts. At the end of the show the host (Lee Jordan, going by a nickname) says  "Keep twiddling those dials: the next password will be 'Mad-Eye'."  Obviously this distribution of an unencoded password to anyone who is listening is not safe practice. Usually I can ignore obvious plot-holes and Deux-ex-machinations, but this was a stretch. I can't think of an explanation for how they could possibly come up with this password distribution method. What exactly are they thinking, how does the scheme work? Both in- and out-of- universe explanations are welcome! PS haven't finished reading. No spoilers please!


I am trying to understand the best way to find the conjugacy classes of $S_3$. What I am doing to find these is first consider what elements would be in the center of the group $Z(S_3)$. Then, after that, I try finding the conjugacy classes for each element of $S_3$ that is not in the group. Namely, I try finding the conjugacy class of 2 cycles, so for $(12)$ and after that I try finding the conjugacy class for 3 cycles like $(123)$. Doing all the work of computing the conjugacies, I found taht the conjugacy class of $(12)$ is $\{(12),(13),(23)\}$ and the conjugacy class of $(123)$ is $\{(123),(132)\}$. Now my question is, is there a more efficient way to find these conjugacy classes, without computing all the conjugacies? For instance for the group $A4$, I think this approach is not efficient and definitely harder to apply. Thanks!


Any news about sticky cursor while scrolling in Emacs?

This is just a remake of the question : it is almost six years old so I thought maybe there are some news.  As explained in that question, I want the cursor in Emacs just stay at the location in the text while I scroll (so it becomes invisible if I scroll more than one window height below or above).  I've got an impression from that question that Emacs fans hate this idea, so let me explain that I really, really need it. Here is why: I am running  in Emacs. While it is computing something, occasionally I want to return back to contemplate what has been already computed. The cursor follows me, and if at that moment GAP produces output, it will go where the cursor currently is, producing big mess sometimes.  It means that I do not necessarily want to make cursor stay where it was. It would be also OK to force GAP placing output where the cursor was before Emacs moved it away. But I suspect that would be much more difficult to do. If not, please tell me how to do it.


So recently, looking at high energy particles through the lens of General and Special Relativity has peaked my interest. One thing I was considering, using the electron as the first example, is as follows:  If gravity is the result of mass (stress-energy tensor), and as particles approach the speed of light, their mass is increased as measured by an outside observer (A) by a factor, $ \frac{1}{\sqrt{(1-(v/c)^{2})}} $.   The mass of the electron, $ m_{e} $, is $ 9.109 \times 10^{-31} kg $, and the radius is $ r_{e} = 2.818 \times 10^{-15} m $.  Given the Schwarzschild Condition is: $$ r_{s} = \frac{2Gm}{c^{2}} $$.  Observer A, due to the Lorentz dilation, will measure a dilated mass term that is increasing monotonically as a function of the electron's velocity. The mass that observer A will then measure is: $$ m_{A} = \frac{m_{e}}{\sqrt{(1-(v/c)^{2})}} $$. Combining the Swarzschild Condition with the mass as measured by A, we attain a relation between the mass that observer A measures with the particle's velocity, accounting for relativistic effects.  This allows me to now pose the question that given the Schwarzschild radius is the electron radius, at what velocity does the mass increase to the point where the electron, as seen by observer A, become a black hole? This also leads to the more conceptual question of what are the implications of simultaneity in this situation? If the electron's mass is still $m_{e}$ in it's own frame, then shouldn't the electron not really turn into a black hole? Of course, this whole argument falls apart if the derived speed is greater than $c$. I went own to calculate that. I found that speed to be:  $$ v = \sqrt{c^{2}-\frac{4G^{2}m^{2}_{e}}{r^{2}_{e}c^{2}}}$$  The velocity at which an object of a given radius and mass would become a black hole.  To my disappointment, this came out to be $8.988 \times 10^{16} m/s $. Over twice the speed of light. I have yet to calculate the velocity for more massive objects, such as stars ( which could theoretically reach relativistic velocities as the result of being flung by a galactic collision ). Either way, if this velocity is attainable for anything, what would simultaneity say about this?


Delete windows completely and install ubuntu on SSD

Currently I have Kubunut 19.10 with windows dualboot and I would like to completely remove Windows and change from HDD to SSD without losing any data at Kubuntu. What would be the "receipt" for that?  Should I first deinstall windows and then change everything to SSD or should I make it in another way?


How many permutations of the alphabets exist such that none of the permutations include the words car,dog,byte,pun

How many permutations on the $26$ English alphabets exist such that none of the permutations have any the following words: car, dog, byte, pun.  First label the words: $$A_1=\text{car}$$ $$A_2=\text{dog}$$ $$A_3=\text{byte}$$ $$A_4=\text{pun}$$ Define $$A_i:=\left\{\text{ permutations on 26 alphabets that do not contain the word with label i}\right\}$$ The desired result can be derived as follows: $$\bigcap _{i=1}^{4}\left|A_i\right|=26!-\sum_{1\le i_{1}\le4}^{ }\left|A_{i_{1}}'\right|+\sum_{1\le i_{1}<i_{2}\le4}^{ }\left|A_{i_{1}}'\cap A_{i_{2}}'\right|-\sum_{1\le i_{1}<i_{2}<i_{3}\le4}^{ }\left|A_{i_{1}}'\cap A _{i_{2}}'\cap A_{i_{3}}'\right|+\left|A_{i_{1}}'\cap A_{i_{2}}'\cap A_{i_{3}}'\cap A_{i_{4}}'\right|$$ $$=26!-\left[\binom{3}{1}24!+23!\right]+\left[\binom{3}{2}22!+\binom{3}{1}21!\right]-\left[\binom{3}{3}20!+\binom{3}{2}19!\right]+\binom{4}{4}17!$$ But I'm not sure if the answer is correct, it would be appreciated if someone checks it.

What is the difference between ~ and / in paths

When I first log in to Unix on my Mac, I usually see a ~ after my username in the command line.  However, if I look at the apps contained in that directory ~/Applications they are not all of my applications, but rather just some of my chrome apps.  If I cd to my / directory, and then go to /Applications there I see all of my applications, so I am wondering what is the difference?  Also, if I go to ~/MY-USERNAME/Applications I see the same as if I just I were just in ~. So what is the difference?  Lastly, how come I can cd into my USERNAME directory endlessly?  (see screen shot, "startec" is my username)


How to Check Associativity for Higher Order Groups, for example, Quaternion Group?

Quaternion group, $(Q_8, .)$ is defined by  $Q_8= \{1, -1, i, -i, j, -j, k, -k\}$  And the binary operation $\cdot$ is defined as follows:  $\forall a\in Q,  1\cdot a=a\cdot 1=a, (-1)\cdot a=a\cdot (-1)=-a$ and $(-1)\cdot (-1)=1$  $i\cdot i=j\cdot j=k\cdot k=-1$    $i\cdot j=k, j\cdot k=i, k\cdot i=j$  $j\cdot i=-k, k\cdot j=-i, i\cdot k=-j$    I need to show that the binary operation $.$ follows the law of associativity. I cannot thought of checking $8^3=512$ cases. Can anyone help me?


Variable defined in a for loop not visible by subfunction (Javascript)

I thought I understood the "closure" behaviour of Javascript, and to prevent the most complex problem of this I usually use "let" instead of "var" in all my code. But it seems it is not enough in this case.  I defined a variable in a for loop (called i here for more conveniance). In my loop, I call a function, which has not any parameters, defined somewhere outside the loop, which use this very variable. But it seems that it cannot reach the value of i, even if it is present in the loop scope.  I know that if I defined the variable i outside the loop, or if I remove let in the for line, it would solve my problem. The question is : why does not my function know the value of i?    function printiValue() {     alert(i); }  let table = [1,2,3]; for (let i of table) {     printiValue(); }


Shell script running but not opening terminal

I'm having a problem executing a shell script in ubuntu, the script is set as executable and I enabled the execute instead of view option in Nautilus and the script does what it's meant to do which is launch a java jar, but it doesn't open the terminal and the app requires interaction from the terminal to function. How do I make it so that it runs the script from within terminal?  Also, I'm using Ubuntu 14.04 LTS and here is the script:  #!/bin/bash java -jar example.jar

Proof of Relationship when Visiting a Friend in Canada

So far I have been able to come thru with Documentation until I arrived at this one :- Proof of Relationship, I am going to visit a friend , after the tour, I am returning home.  How Can I show the visa officer that this is my friend. I do not have any documentation of him, I just included that I got a letter from him and seeing this proof of relationship, I am a bit confused. I Decided to ask on here to clear the air on that very issue. How can I prove relationship in this case.


Add multiple fields to a batch of layers in QGIS?

I have multiple polygon .shp files that are denoting farm boundaries. The sources are varied and the original fields vary in name and number. These boundary files are to be imported into a Farm Management Software and require specific fields for identifying the data on import. The data in the fields will have to be entered manually. I am using QGIS 2.18  I have limited knowledge of scripting. A plugin would be awesome. I am aware of the "Add Field" in the Processing Toolbox. I could add each field separately through the batch function.  Is it possible to add more than one field to a layer in a batch configuration?

Im wondering if there is a regular expression pattern that will validate if a credit card expiration date is before todays date.  In my form i have users entering in credit card expiration dates, and need some sort of client validation as we use a direct post API with a gateway provider and no server side validation can occur during this process.  The date fields are in 2 seperate fields with month and year but we need to ensure that we catch them before they are submitted to the gateway incase it fails, as the gateway returns ugly string messages that we cant avoid.  Any ideas on this would be greatly appreciated.


How is it that the cross product of two vectors is always perpendicular to the given vectors?

Vector addition, subtraction and dot product seem logical enough, but I don't understand how two vectors acting on the same plane maybe, can give a perpendicular resultant.


Techniques to prove a function is uniformly continuous

So I understand the definition of uniform continuity, but wanted some suggestions to prove that a function is or isn't uniformly continuous. I have looked ahead and have seen that if a function is continuous on a compact domain, then the function is also uniformly continuous. But for the purposes of the examples below, I cannot use compactness, or the fact that a function is uniformly continuous if it is continuous and has a bounded derivative. Here's one example:  prove $f(x)= \sqrt{x}$ is uniformly continuous on $(0, \infty)$. I have seen this question asked before on this forum, and the respondents used the traditional definition. Ie. they found a delta such that if $|x-y|<\delta$, then $|\sqrt{x}-\sqrt{y}|< \epsilon$. I was wondering if I could try this in a slightly different way. Suppose I prove that $f$ is continuous at $x_0$, and the choice of $\delta$ doesn't depend on $x_0$. After some scratch work, I proved that $f(x)$ is continuous at $x_0$ provided that $|x-x_0|< \min\{1,(\sqrt{x_0+1} + \sqrt{x_0})*\epsilon\}$. Since $x_0$ is always greater than $0$, we can say that $\delta= \min\{1, \epsilon\}$. Because I proved that our choice of $\delta$ doesn't depend on $x_0$, is this a valid proof that $f(x)$ is uniformly continuous? Here's another example: I want to prove that $f(x)=x^2$ is not uniformly continuous on $(0, \infty)$. After some work, I proved that $f(x)$ is continuous at $x_0$ (in dom $f$), provided that $\delta< min \{1, \frac {\epsilon}{ (2x_0+1)}\}$. Here, since our choice of delta does depend on $x_0$, we can say the function is not uniformly continuous. So am I approaching these problems correctly? I realize that I have not been using the definition of uniformly continuity. (that if $f$ is uniformly continuous, then if $|x-y|<\delta$, then$|f(x)-f(y)|< \epsilon$. Also, sorry about the formatting. I realize I should learn proper formatting soon!. Also, I have read the following post regarding this topic:


Explicit bijection between $\mathbb N$ and $\mathbb N \times \mathbb N$

We can consider the quadratic scheme above for a possible explicit bijection between  $\mathbb N$ and $\mathbb N \times \mathbb N$.  The part $\mathbb N \times \mathbb N \to \mathbb N$ is easy via $(m,n) \mapsto m + \frac{(n + m)\cdot(n + m + 1)}{2}$ for $m$ going down (as row index) and $n$ going right (as column index).   Consider $(0,0) \mapsto 0$ and $(2,1) \mapsto 8$ and $(3,2) \mapsto 18$ as examples.  What ist the other map $\mathbb N \to \mathbb N \times \mathbb N$?


What are some examples of awkward sounding but grammatically correct sentences?


If we consider the space given by $\{(x_{1}, x_{2}, ..., x_{n}) : (x_{1}, x_{2}) \neq (0, 0)\} \subset \mathbb{R}^{n}$, for $n \ge 3$, how can we show that it is path-connected? For $n=3$, the space is just $\mathbb{R}^{3}$ with the z-axis removed, so intuitively I know to construct a straight line composition around the removed axis, but not sure how to put do it explicitly. As for higher dimensions I am really stuck as I cant even visualize what the space looks like. Was thinking maybe a homeomorphism from a space we know is path connected such as $\mathbb{R}^{n}-\{0\}$, since it would preserve the path-connectedness condition.
