I'm playing Fallout Shelter, and my newest bonus objective is to "Deliver 1 Baby Dweller."  I've already figured out that I can put a male vault dweller and a female vault dweller together in some residential quarters, and and eventually, if they hit it off, the lady will replace her vault suit with a yellow sweater and a decidedly pregnant figure.   Good enough.  But how long does it take her to deliver the child? Do I have to induce it through some sort of tapping ritual or placing her in the correct room? Does the pregnant dweller need to stay in the living quarters, or can I put her to work in my Diner or Water Treatment Facility? Do the SPECIAL stars of the parents matter?  Tell me everything about  and what I can do to control the process.


Ubuntu 18.04 hangs when using Google Chrome, Mozilla Firefox and Thunderbird

System Info:   Model Name: Lenovo ThinkPad 11e RAM: 4G Product Page:  Graphics and Driver Info:    00:02.0 VGA compatible controller [0300]: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0e)  Subsystem: Lenovo Atom Processor Z36xxx/Z37xxx Series Graphics & Display [17aa:2224]  Kernel driver in use: i915  Kernel modules: i915    App versions:   Google Chrome: Version 67 in both Ubuntu version(16.04 and 18.04) Mozilla Firefox: Version 60 in both Ubuntu version(16.04 and 18.04) Thunderbird: Version 52 in both Ubuntu version(16.04 and 18.04)   What happens:   I usually browse with multiple tabs open and suddenly the mouse and keyboard freeze and and I am forced to restart with the power button.  None of the shortcuts work once the system hangs. This happens almost every time I use the system.   Worst to Best:   Google Chrome - Hangs with just 3-4 tabs of YouTube open. Thunderbird - Hangs when present with lesser number of tabs (3-4) of Mozilla Firefox. Mozilla Firefox - Hangs with 8+ tabs present with heavy video or image  presence.   Things I have tried:   Re-installation   Current solution:  Got fed-up and downgraded to 16.04.4 which has been stable so far. Have been using 14.04 previously for many years with no issues.


I have one file with hundreds of unique IP addresses (each on a separate line) from which a bot tries to login to one of our services. I would like to see which of these addresses appear in another logfile.   Should I script this, or is there an ingenious way to do this with a single command in the terminal?


Is the expression "having a kitten in one's pocket" a proverb or slang?

Is the phrase, from ‘The Man Who Knew Too Much’ by Alexander Baron     having one's kitten in one's pocket   a proverb or common slang? How common is this expression? What exactly does it mean and how can this phrase be used?

How do I use texture maps in Cycles nodes?

What I did:   Change render engine to Cycles Add Suzanne Add plane Scale plane by 5 Change environment texture to HDRI from  Change Suzanna node setup Change plane node setup (use default principled BSDF, add image textures for diff (diffuse), spec (specular), rough (roughness), normal, disp (displacement)) Change all image textures to non-color data except for diff (diffuse) and normal   The specific texture for the plane is . I am given the option to download:   Diffuse AO (unused) Bump (unused) Displacement Normal Roughness Specular   Is this the correct node setup to use the texture and how do I connect the unused textures?  I am using Blender 2.82a. The wood plane looks flat to me even though I added the normal and displacement nodes.  Nodes:    Render:

Answers for questions are not ordered by votes

I have noticed that now the answers to questions are not sorted by votes anymore. Is this a new feature?  For example,  (though you may need to refresh... random, you know..)  I assume it is related to some meta question, but I didn't find such.


I have some map files consisting of 'polylines' (each line is just a list of vertices) representing tunnels, and I want to try and find the tunnel 'center line' (shown, roughly, in red below).

Any ideas on how I might be able to do this?  I'm working in fairly raw C++.


How to get appendix (sub)sections not detailed in the main table of contents, but detailed at the beginning of appendix?

In a report document with appendices, Appendix chapter's title should appear in the main table of contents without the section's, subsection's, etc., title it contains. At the beginning of the appendices, their should be a local table of contents only with the titles of sections, subsections, etc., it contains.  In practice, the following scheme:  \maintableofcontents \chapter{Some Chapter} \section{Some Section} \section{An Other section} \chapter{An Other Chapter} \section{A Section, Again} \section{An Other Section, Again} \appendix \chapter{Appendices} \localtableofcontents \section{Some Appendix} \section{An Other Appendix}   should give something like(*):  Table of contents  Some Chapter       1 Some section       2 An Other section An Other Chapter       1 A Section, Again       2 An Other Section, Again Appendices  (here the main content)  Appendices  1 Some Appendix 2 An Other Appendix  (here the appendices' content)   How to get this?  (*) Note that, in this specific case, chapters have been redefined to be unnumbered.


Integrating product of multivariate normal and univariate normal to find marginal

Suppose, $y_i|u_i\sim MN(X_i(t_i), \sigma_e^2I_{m_i})$ and $u_i\sim N(0,1)$. Now how to find the marginal distribution of $f(y_i)=\int f(y_i|u_i)f(u_i)du_i$? Since one is multivariate normal and other is univariate normal, can we actually find the product before the integration? Or it will be a no-closed form expression? Even if it's the case, how do we come up with the no-closed form expression? Here $X_i(t)=\dfrac{exp[Z_i(t)]}{\int_a^dexp[Z_i(s)]ds}$ and $Z(t)= b(t)^Tc+b(t)^TAU $ So $X_i(t)$ is determined by $u_i$ via $Z_i$


Appending files to initramfs image - reliable?

I'm modifying a bunch of initramfs archives from different Linux distros in which normally only one file is being changed.  I would like to automate the process without switching to root user to extract all files inside the initramfs image and packing them again.  First I've tried to generate a list of files for gen_init_cpio without extracting all contents on the initramfs archive, i.e. parsing the output of cpio -tvn initrd.img (like ls -l output) through a script which changes all permissions to octal and arranges the output to the format gen_init_cpio wants, like:  dir /dev 755 0 0 nod /dev/console 644 0 0 c 5 1 slink /bin/sh busybox 777 0 0 file /bin/busybox initramfs/busybox 755 0 0   This involves some replacements and the script may be hard to write for me, so I've found a better way and I'm asking about how safe and portable is:  In some distros we have an initramfs file with concatenated parts, and apparently the kernel parses the whole file extracting all parts packed in a 1-byte boundary, so there is no need to fill each part to a multiple of 512 bytes. I thought this 'feature' can be useful for me to avoid recreating the archive when modifying files inside it. Indeed it works, at least for Debian and CloneZilla.  For example if we have modified the /init file on initrd.gz of Debian 8.2.0, we can append it to initrd.gz image with:  $ echo ./init | cpio -H newc -o | gzip >> initrd.gz   so initrd.gz has two concatenated archives, the original and its modifications. Let's see the result of binwalk:  DECIMAL       HEXADECIMAL     DESCRIPTION -------------------------------------------------------------------------------- 0             0x0             gzip compressed data, maximum compression, has original file name: "initrd", from Unix, last modified: Tue Sep  1 09:33:08 2015 6299939       0x602123        gzip compressed data, from Unix, last modified: Tue Nov 17 16:06:13 2015   It works perfectly. But it is reliable? what restrictions do we have when appending data to initfamfs files? it is safe to append without padding the original archive to a multiple of 512 bytes? from which kernel version is this feature supported?


This question is clearly not off topic, as it directly pertains to Docker. I think this belongs on here, possibly Server Fault, but there is a tag for it here. I had to remove all references to my use-case because people thought it was off-topic.


How can I reorder my divs using only CSS?

Given a template where the HTML cannot be modified because of other requirements, how is it possible to display (rearrange) a div above another div when they are not in that order in the HTML? Both divs contain data that varies in height and width.

         Content to be below in this situation

         Content to be above in this situation

 Other elements   Hopefully it is obvious that the desired result is:  Content to be above in this situation Content to be below in this situation Other elements   When the dimensions are fixed it easy to position them where needed, but I need some ideas for when the content is variable. For the sake of this scenario, please just consider the width to be 100% on both.  I am specifically looking for a CSS-only solution (and it will probably have to be met with other solutions if that doesn't pan out).   There are other elements following this. A good suggestion was mentioned given the limited scenario I demonstrated—given that it might be the best answer, but I am looking to also make sure elements following this aren't impacted.

Interpretation of fitted probabilites in binary logistic regression

I run a simple binary logit regression with a single dummy as IV. The output gives log odds and is:      Intercept: 0.3045   Female:    0.4521   Calculating the odds ratio for female is $exp(0.4521) = 1.572$ and I usually interpret it like this: "If the person is female, this multiplies the odds of Y = 1 by 1.572."    I was now interested in the probability and couldn't get my head around it. First I calculated the probability from the OR for female, which is $\frac{1.572}{1+1.572} = 0.61$. I thought it translates into something like: "If the person is female, the probability of Y = 1 increases by 61%". However, when calculating the fitted probability of Y = 1 | female and Y = 1 | male I get:   $\frac{exp(0.3045+0.4521)}{1+exp(0.3045+0.4521)} = 0.681 $ for female and  $\frac{exp(0.3045)}{1+exp(0.3045)} = 0.576 $ for male.   This is clearly no increase by 61% from male to female.    My question: How does the probability of 0.61, calculated above, relate to the fitted probabilities? Did I do anything wrong?   Cheers!

which app triggers the "Windows features" dialog?

I keep getting this window titles "Windows Features" It then says that:     An app on your PC needs the following Windows feature:      .NET Framework 3.5 (Includes .NET 2.0 and 3.0)   and I can choose to install or skip (being warned that my apps might not work correctly).  There is also a "telll me more about this feature" link but it explains about the .NET framework.  I want to know if there is a way for me to know which application is it that asks for this feature as the window just keeps popping out of the context of activating a new app...  This all started just a few days ago after some unattended update on my windows 10.

Why do loose edges in a tikz graph create empty space?

I want to create an automaton in tikz and adjust the looseness and bend properties of the edges. If I set the values high, it creates a lot of empty space to the left and below the graphic. In my document, this makes it shift to the right, partially off the page. Here is an mwe.  \documentclass{standalone} \usepackage[dvipsnames]{xcolor} \usepackage{tikz} \usetikzlibrary{automata,calc,positioning} \begin{document}    \begin{tikzpicture}[          node distance=3cm,          clique/.style={fill=SkyBlue},          font=\sffamily,          thick,    ]       \node[clique,state] (B) {B};       \node[clique,state,below=of B] (A) {A};       \node[clique,state] at ($(B) !.5! (A) + (2cm,0)$) (C) {C};       \node[clique,state,right=of C] (D) {D};       \node[state,above=of D] (E) {E};       \node[state,right=of D] (F) {F};       \node[state,below left=of F] (H) {H};       \node[state,below=of F] (G) {G};        \path       (A) edge[bend left] (E)       (A) edge[bend right=10] (F)       (A) edge[bend right] (G)       (A) edge (D)        (B) edge[bend right=100,looseness=1.6,out=270] (H)       (B) edge[bend right=100,looseness=1.6,out=260] (G)       (B) edge[bend left=100,looseness=1.2] (F)        (C) edge[bend left=10] (G)       (C) edge[bend left=20] (F)       (C) edge[bend right] (H)       (C) edge (E)        (D) edge (E)       (D) edge (F)       (D) edge (G)         (E) edge (G)       (E) edge[bend left=80,looseness=2] (H)       ;    \end{tikzpicture} \end{document}   The result is this:    I would have it trimmed to the actual content, as standalone usually does. What causes this and how do I get rid of it?

If $x^2+ax+b=0$ has a rational root, show that it is in fact an integer

I have tried as follows. Please help to double check the proof! Thank you!  Since $x=p/q$ ($p$, $q$ are integers), $(p/q)^2+(p/q)a+b=0$  So, $(p/q)^2=-b-a(p/q)$  then, $p^2=-bq^2-a(p/q)q^2$  and, $p = \dfrac {q(-bq-a(p/q)q)}{p}$  now, it is clear that $q \mid p$, thus $p/q$ must be an integer.

Nature and number of solutions to $xy=x+y$

Find all solutions to $$xy=x+y$$ Initially the given condition was $x,y\in \Bbb{Z}$.    $$$$In this case, I just guessed that the solutions were $(0,0)$ and $(2,2)$. As far as I can see, these are the only 2 integral solutions possible. However, i'm quite surprised as usually a Diophantine Equation has infinite solutions. Could somebody please show me how to actually $solve$ this equation instead of just guessing the values? Is there any way to $show$ that there are just 2 sets of solutions?  $$$$Secondly, what if $x,y\in \Bbb{R}$? In that case how could the equation be solved? $$$$For both these conditions on the values of $x,y$, is there any way to use Coordinate Geometry to achieve an answer? $$$$ Many thanks in anticipation!  Edit: I forgot to mention that I know the solution using factoring. I was hoping to find a solution using Coordinate Geometry. I was told by a friend that the non integral solutions lie on 2 unique lines, and am hence particularly interested in a geometrical solution.

Latex sectioning, mixing arabic and alphabetic

As the title suggests I want to start off with Arabic section counting and continue with alphabetic for the source codes. It should look somewhat like the following.  Currently, I achieve this by renewing the section command as follows: \renewcommand\thesection{\Alph{section}} \setcounter{section}{0}  But this results in a problem with the hyperlinks. If I no click on A Source Code: Gridworld Environment, it navigates to the Introduction. Somehow the hyperlinks are messed up, and I don't know how to fix it.

Boolean not breaking while loop. Assigning and checking equality are OK

I can't believe I can't see what I'm doing wrong as this is something a beginner like me should already be used to...  I have the following code:  boolean doWhile = true; while (doWhile == true){      String s = sc.nextLine();      if (s == "something"){           doWhile = false;      }      //DoStuff }   Unfortunately, when s == "something", it doesn't break the loop, but instead continues to read the rest of the code.  I've searched around and a lot of people seem to make this mistake, but in their cases they messed up with the = and == things.  I'm pretty sure = is for assigning and == to check equality. I also tried while(doWhile) and while(!doWhile) with the boolean to false, but nothing seems to work and I can't seem to wrap my head around something so simple.  EDIT: .equals() doesn't work either. Also, I've used == in this way before and it worked without a problem. Not sure why it's making a fuss right now. EDIT3: No solution here:  The solution was provided by harold.


Whenever I review Close Votes, I sometimes stumble upon something that I don't think should be closed, but just to make sure I haven't missed something, I press the "Close" button to see how many people have actually voted that something is e.g. off-topic or what is going on.  Unfortunately, this method is faulty, because from time to time I'll be met with this message which I'm sure we're all familiar with.    And all of a sudden, I feel bad and feel like I've done something wrong, even though I haven't actually voted to close anything, I just wanted to peak.  Therefore, I have a question and a request:  Question: Are those times where I apparently don't pass the test getting recorded? If I keep using this method, will it eventually have some effect on my voting?  Request: Can we not make the error message show up until reviewers have clicked "Vote to close"? In the dialog, it shows many people have voted. Just adding random votes in here will only further my confusion to the close reason, but not having any votes in there will also be "suspicious". Exactly how this can be changed, I don't know; I just know that I don't like getting told to stop and listen for no reason...sob.


How do I prevent my keyUp event listener from firing multiple times

Okay, before asking this question, I was sure there already was an answer on stackoverflow for this... but I can't find anything so here goes:  I'm using flask to create a website. One part of it to is to make comments.   When I click enter, it should submit the form to add a comment to the Database.  Here is my code for that:  (This is the form)  <form method="POST">     {{ form.hidden_tag() }}     {% if form.comment.errors %}         {{ form.comment(id="comment-input", class="new-comment", placeholder="Add a new comment", autofocus="autofocus") }}
             {% for error in form.comment.errors %}                 {{ error }}             {% endfor %}
     {% else %}         {{ form.comment(id="comment-input", class="new-comment", placeholder="Add a new comment", autofocus="autofocus") }}     {% endif %}     {{ form.submit(class="btn btn-outline-info", id="submit", style="display:none;") }} </form>   And I'm using this javascript to submit the form when the enter key is pressed:  var input = document.getElementById("comment-input"); input.addEventListener("keyup", function(event) {   // Cancel the default action, if needed   event.preventDefault();   // Number 13 is the "Enter" key on the keyboard   if (event.keyCode === 13) {     // Trigger the button element with a click     document.getElementById("submit").click()   } });   The problem is, usually if I press enter after typing my comment, it works fine but if I hold down enter after typing my comment it submits multiple comments.  But if you look at my code it says keyUp not keyDown! I'm pretty sure when you hold down a key down, it still only keyUp once.  I've looked through stackoverflow, etc for about 2 hours now, hopefully this question will help my situation.


Q) $\{X_n\}$,$\{Y_n\}$ are positive integrable and adapted to $\mathcal{F_n}$. Suppose $E(X_{n+1}|\mathcal{F_n})\leq X_n+Y_n$, with $\sum Y_n < \infty$ a.s. Prove that $X_n$ converges a.s. to a finite limit.   The first part of the answer is: Consider $W_{n}= X_n - \sum_{k=1}^{n}Y_k$ and the claim is that it is super martingale which I don't get.   $$E[W_{n+1}|\mathcal{F_n}] = E[X_{n+1}|\mathcal{F_n}]-\sum_{k=1}^{n+1}E[Y_k|\mathcal{F_n}] \leq X_n-\sum_{k=1}^{n}E[Y_k|\mathcal{F_n}] + Y_n-E[Y_{n+1}|\mathcal{F_n}] = $$ $$W_n+Y_n-E[Y_{n+1}|\mathcal{F_n}]$$  So I don't understand why $Y_n-E[Y_{n+1}|\mathcal{F_n}] \leq 0$? It is not given that $\{Y_n\}$ is a sub martingale. Thanks and appreciate a hint.

Star Trek in-universe timeline versus external events: when did they separate?

It's clear from the 1992 start date of the Eugenics Wars that Star Trek's timeline has already diverged from ours. Are there any earlier points of divergence? In DS9's "Little Green Men" episode, Quark and company traveled back to Roswell in 1947, but that caused no apparent changes.  I can't think of any earlier events, but I'm not an expert.


How do I programmatically remove menu tabs from the user login page?

In Drupal 7 I could remove tabs using hook_menu_alter() like below:  /** * Implementation of hook_menu_alter */ function MY_MODULE_menu_alter(&$items) {     $items['user/register']['type'] = MENU_CALLBACK;   $items['user/login']['type'] = MENU_CALLBACK;   $items['user/password']['type'] = MENU_CALLBACK;   }   This hook has been removed from D8 and is now handled by altering routes. However, I cannot figure out how to remove the these tabs from the user login page.

I suggested an edit to a question but that revision was reject. Where can I find the particular suggested edit, or better yet the question itself? I would like to try and reword the question again.


After adding a comment, SO says there are new comments to show, but it is only yours?

For a few days now, when I add a comment, SO will (sometimes) show my comment and indicate that there are one or more new comments, and on showing the new comments, it is just my comment that is shown.  Just now, it told me there were 6 new comments; there weren't — there was just mine.  SO didn't used to get confused about that.  Please fix it so it is unconfused once more.    Specific context: .  I set out to reproduce it — the site recognized that it was under scrutiny and refused to cooperate.  The problem seems to be intermittent, or to depend on the sequence of actions you undertake.  But I've noticed it on and off for most of this week.  I don't think it depends on having a lot of comments; I've seen it with a couple of comments in the question.  I'm not sure whether it is restricted to comments to the question; I think it can occur with comments to an answer too.  I've seen it with both Firefox (23.0.1) and Chrome (29.0.1547.57) on Mac OS X 10.8.4.  Documentary Evidence  Question:   When the question is first loaded there are a number of hidden comments (now 10, was 9 when I started):    When I added a comment, it said there were 8 more to show:    When I tried to show the '8 more comments', they weren't there:    After reloading and redisplaying, the comments available were:    Strictly speaking, the images were generated in the order 2nd ('8 more'), 3rd ('not 8 more'), 1st ('10 more'), and 4th ('look at them all').  I've not tried adding yet another comment.  But this bug is still active a week or more after I reported it, and a month or more after it was first reported.


How do I create an icon shortcut in the linux - Centos navigation system?

I downloaded a program called SmartCVS which came in a tar file which I extracted and stored into my home folder. To run the program, I use the terminal and enter my home folder and then into the program's folders -- (/home/username/smartcvs-7_1_9/bin) -- and run   [user@localhost]$ ./smartcvs.sh   to start the program. I however would like to add a shortcut here to run this program.


How can $\sum_{n=1}^\infty \frac{1}{n}$ be simplified

So I'm doing year 9/10 now and I've just been working with sigmas $\Sigma$.  I found across a question which I found quite tricky.  Is there a way to write down the answer to this question or make it easier:  $$\sum_{n=1}^\infty \frac{1}{n}$$


in python you can define a class A  class A(object):     .....      def __call__(self, bar):         #do stuff with bar         ....   which allows me to use it like this:  bar = "something" foo = A() foo(bar)   I would like to do the same thing in c++, but I did not find anything, Is this possible or did I overlook something?

How many downvotes do you have to get to be banned from questioning/answering

I was recently banned from having the ability to ask questions on Stack Overflow. I have read all the articles about why I was banned and I am not asking to explain why. I would like to know how the system knows when to ban you from asking a question or giving an answer.  Is there a certain number of downvotes that you have to get on questions, like a -6 reputation for asking questions, or is it more than that? I would just like to know for future purposes of what to shoot for when asking a question.  I'm not necessarily asking for the number of downvotes or anything specific. I just want to know what it is based on. Because I have only asked 1 duplicate question and 6 with no votes/downvotes. So I just wanna know if it is based off of something else like user reports

We want to find harmonic functions $w$ in (say) $\mathbb{R}^2$ that are zero on $\{y=0\}$ with the linear growth bound \begin{equation} \sup_{\mathbb{B}_R} |w| \leq C(1+R) \end{equation} where $C>0$ independent of $R$, are the only solutions to such a problem $w(x,y)=ay$ for some $a \in \mathbb{R}^2$?  I cannot think of a method to even start this at the moment as the usual tools (like mean value property or Harnack) do not seem to give anything of use. I feel like it is possible an application of Harnacks inequality in a clever way might do it?


Integral $\int_{-2}^0 \frac{x}{\sqrt{e^x+\left(x+2\right)^2}} dx$

The value of the integral $$ \int_{-2}^0 \frac{x}{\sqrt{e^x+\left(x+2\right)^2}} \,dx,$$  is: (a) $-1 \,\,$ (b)$-2 \,\,$ (c) $-e\,\,$  (d) $2 - e\,\,$  (e) another answer  (yes, this is one of the options)  I am having trouble solving this question. It seems like this integral has no elementary primitive and wolfram can offer only a numeric value which does not satisfy the given answers. Maybe this exercise is wrong or something but I am not sure, it is after all for an examination, so I do not know if they made a mistake or not.


Choosing the right linkage method for hierarchical clustering

I am performing hierarchical clustering on data I've gathered and processed from the reddit data dump on Google BigQuery.   My process is the following:   Get the latest 1000 posts in /r/politics Gather all the comments Process the data and compute an n x m data matrix (n:users/samples, m:posts/features) Calculate the distance matrix for hierarchical clustering Choose a linkage method and perform the hierarchical clustering Plot the data as a dendrogram   My question is, how do I determine what the best linkage method is? I'm currently using Ward but how do I know if I should be using single, complete, average, etc?  I'm very new to this stuff but I can't find a clear answer online as I'm not sure there is one. So what might be a good idea for my application? Note the data is relatively sparse in the sense that the n x m matrix has a lot of zeroes (most people don't comment on more than a few posts).

Most paradoxes involves self-reference, the only exception known to me is Yablo's paradox, however it is still debated if it is really without self-reference. So, I was wondering, are there other known paradoxes that works without self-reference?


How to stop a minecart at a random moment?

I'm working on a roulette table on a server that I'm playing on, inspired by :       It uses a minecart with an armor stand inside it. The minecart is not visible, but the top of the iron helmet on the armor stand is visible like a moving square on top of the diferent-coloured carpets above the minecart. The minecart goes in a circle (about 3x3 blocks big) on powered rails, until a player flicks a lever and stops the minecart by turning off the rails.   The main flaw of this is that the moment the roulette stops isn't random. This could cause some arguing between the players. How can I avoid this problem? Is it possible to have a button that will stop the rails at a random moment instead of the lever?  It would also be nice if you could avoid using too complicated redstone circuits and command blocks.  Note: You can check out MagmaMusen's video "" if you didn't get the way it works from my explanation.


Why is the emf over an inductor equal to that of the battery?

In a hypothetical circuit with only an inductor and a DC voltage source (no resistance), why is the voltage across the inductor the same as the source voltage? I get that the charges coming from the battery need to lose their energy, so do so over the inductor, but surely when the voltage across the battery and inductor are equal, there is no net voltage acting on the current, and so no change in current and so no back emf? Thanks :)


For example I have a domain www.store.com which provides sub stores to clients as subdomains client1.store.com, client2.store.com etc..I am using wildcard ssl certificate for store.com and all subdomains.  My client store 1, has a main site and they provide their store site as store.clientsite.com which displays our subdomain for the client. They add a CNAME record in their DNS for store.clientsite.com with alias as client1.store.com.  In my store.com site for the subdomain client1.store.com we add in apache config, Server as  client1.store.com and Server Alias as store.clientsite.com in the apache config.   It works perfectly as , but with  the browser is displaying a warning. The client has tried it with no ssl added and with wild card SSL added. Both gives same result.  If we need to display the https:// site by Redirect permanent /  the  url gets redirected to . So it is not possible.  How is it possible to display  with CNAME alias client1.store.com without displaying browser warning and in https://.  Help requested from experts.

So I came across this exercise: Show that if $Y$ is path-connected then the set of homotopy classes $[I,Y]$ of maps of $I=[0,1]$ into Y has a single point.   But I am confused here. If $Y=S^1$ then not all loops are homotopic! I mean, isn't true that $\pi_1(Y)\subset [I,Y]$? Or maybe I don't understand the set $[I,Y]$ well!


Seeking vector data for wind speed and operating turbines in UK?

I have been familiarising myself with QGIS and the free information Ordnance Survey provide. Though I'm struggling to find further data specific to my needs.  I want to produce a map plotting renewable energy in the UK (or at least operating wind turbines) against locations of operating data centres, preferably on a background of wind speeds.   Are there places where I access this data?  By so far I have seen only these sources:   This website provides locations of data centres:   This renewable energy:  This has wind speed but when I import it is all the same colour:

How to add multiple round holes to a mesh?

I need to add several holes into a mesh, like you would have on the top of a salt shaker:    I tried using the boolean modifier, as well as knife project with a circle, before I realized that the subdivision surface modifier was already rounding square shapes into circles.  With this I can just delete a face without any supporting edges that will look like a circle, and this works fine for 1 hole. However when I try to have several holes and apply the subdivision surface modifier the geometry does crazy things that I am not understanding:            I am unsure how to proceed to have several holes in this mesh.


What's the least class of ordinals closed under successor and the limits of omega-sequences?

What is the smallest class $S$ of ordinals that contains $0$, closed under successor and the limits of omega-sequences, i.e., $$ \forall i \in \omega [\alpha_i \in S] \Rightarrow \sup_{i} \alpha_i \in S. $$  Will it be an initial segment of the class of all ordinals?  Or will it contain all ordinals of cofinality $\aleph_0$?  What other ordinals does $S$ contain?  Background: I've been reading Chapter 6 of Proofs and Computations by Schwichtenberg and Wainer, where they explain the generalized recursion theory in the abstract setting, in the style of Scott/Plotkin.  There, they give a type-theoretic definition of ordinals: the type of ordinals is $$ \mathbf O := \mu_\xi(\xi, \xi\rightarrow\xi, (\mathbf N\rightarrow\xi)\rightarrow\xi). $$ where $\mathbf N$ is the type of naturals. I assume this consists of three constructors, each of which corresponds to zero, successor and limits, respectively, and I believe $\mathbf O$ corresponds to the class $S$ defined above.


How can I remove an unwanted fragment of old GUI on my screen? (Windows 7)

Note- this is for Windows 7.. this one  is  for vista   So it is not a duplicate.. And also the changing the resolution(the accepted answer on that one), didn't fix it for me.  there may be a windows 7 specific answer    Here is a bit of the desktop.    At some point some old bit of GUI appeared and won't go away.  Here it is hovering as I write this question.    It just sits there. And as you can no doubt appreciate,  it is a nuisance.  I've tried clicking in the bottom left to mimimize all the windows and clicking again to restore but nope. And i've tried opening a window over it but it just won't paint over it. The unwanted bit of GUI stays on top of anything.  I have tried opening task manager, end tasking explorer and starting explorer again, but nope, still there. so besides restarting windows, what can I do?  added  And I tried the accepted answer here   (and probably some others too) and the accepted answer of changing resolution, and some others I tried there, didn't work

Is there a shorthand way to 'Auto_Fix' all Orphaned Users in an SQL Server 2008 R2 database?

It's fairly straight forward to fix up a single orphaned SQL user to a login using:     EXEC sp_change_users_login 'Auto_Fix', 'user'   I could script this, but is there an existing stored procedure which automatically tries to fix up every orphaned user in a given database?


How to use Freight Sans Pro in TexMaker?

I know that there are loads of questions like this, but I'm such a tex-rookie, I haven't been able to find an answer.   I need to use the font Freight Sans Pro in my Tex-document. I have the font downloaded, but I have no idea how to actually implement it in my document. I've gotten so far that I understand that I probably need to run it with XeTex og LualaTex. However, I don't know that my next step is.    Where am I supposed to save the font on my computer?  How do I decide between xetex and luatex?  What packages/commands do I need to use I've placed the font right?    I hope you guys can help a new tex'er out here!


Scripting Language for Java and its uses?

So I am going to work on a Java game and recently my friend suggested I use a scripting language to help development go smoother/faster.  so far I used XML as data storage and to make the HUD/UI but he recommended I learn Ruby, Python, Groovy, and/or Lua.  he Strongly recommended Lua for the same thing i use XML for.  basically what my question is :   What are scripting languages, what are they for,, should I use a scripting language, whats the difference between said scripting languages and XML, and which one should I learn and use for my java game?

Have to press down hard for keys on keyboard to work?

My mid-2010 MBP is malfunctioning. For all the keys I have to press down quite hard to get a response. "slow keys" is off. I spilled some water around the keyboard a few days ago, that's about when this started. I started popping keys off and it was rather dirty under each key, I cleaned them with a cotton swap and rubbing alcohol. Has made an improvement, more responsive but still hard to press. Is there another method for cleaning them better. Or something else that could cause low responsiveness?

What is the most risk-free way to invest a lump sum of cash for 1-2 years?

I received a signing bonus with my most recent position for which, if I leave the company after one year I must return half, and can keep the entire amount if I stay two years. I am a very risk-averse person so I don't want to spend the money and be completely locked in if I decide I want to leave. My question is - where can I put this cash such that it will gain the maximum amount of interest with nearest-to-zero risk and decent liquidity? Since the case in which I would actually need to withdraw it would necessitate me returning much of it, it would be important to have access to almost the entire sum (I could sustain a 10% drop say, but 30% would be a real kick in the teeth). I've been looking at CDs and bonds, it is my understanding that bonds would perform better in a low-inflation environment like the one we're in, but I am unsure and also looking for other investment vehicles to consider.

Resolve cross-site links to question title

When I post a link to another post on the same site, it resolves the link to the question title. When I post a link to Stack Overflow from Database Administrators, cross site, it doesn't.  I know I could make it a proper link and all that, but I'm lazy I do like the automatic resolution of links. Would it be possible, or is it ?  I note intra-site is here but no mention (OK, one comment) for cross-site:   Edit, 14 Nov 2011: any comment by the management?


Suppose $f:\mathbb{C}\rightarrow\mathbb{C}$ is an entire function. Let $g:\mathbb{C}\rightarrow\mathbb{C}$ be an entire function, which has no zeros.    I have shown that $\vert f(z) \vert \leq \vert g(z) \vert$ for all $z\in\mathbb{C}$ implies $f(z)=Cg(z)$ for some constant $C\in\mathbb{C}.$  I have to decide if this also holds if $g$ is allowed to have zeros. Help?


I have this task about cards:     Consider choosing a card from a well-shuffled standard deck of 52   playing cards.           Suppose that, after the first extraction, the card   is not reinserted in the deck. What is the probability that the second   card is an ace?   Suppose that, after the first extraction, the card   is reinserted in the deck. What is the probability that the second   card is an ace?      For the first case, I've been thinking about $$\left(\frac{4*3}{52*51}\right) + \left(\frac{48*4}{52*51}\right)$$ Where I counted two examples: a)the ace was drawn already, and b) it wasn't. For the second part of the task, would it be $$\left(\frac{4*4}{52*52}\right) + \left(\frac{52*4}{52*52}\right)$$ I'm pretty sure that I'm assuming wrong, but I can't come up with anything else. Any help would be great!


Unable To Meet MAC Address Condition Check - Android / Java

I'm attempting to check to ensure the device has a MAC address set using java - however I'm having trouble implementing the check to do so. I've attempted to use the following:  if (MAC == "00:00:00:00:00:00"){                   AlertDialog.Builder builder = new AlertDialog.Builder(ActivityMain.this);                 builder.setMessage("You Have No MAC Address!")                        .setCancelable(false)                        .setPositiveButton("OK", new DialogInterface.OnClickListener() {                            public void onClick(DialogInterface dialog, int id) {                                 //do things                            }                        });                 AlertDialog alert = builder.create();                 alert.show();              }   However the condition is never met - even with the value of MAC set to 00:00:00:00:00:00.  I thought this might be the way I am comparing to the two values. So then I tried this:  if (MAC = "00:00:00:00:00:00"){                   AlertDialog.Builder builder = new AlertDialog.Builder(ActivityMain.this);                 builder.setMessage("You Have No MAC Address!")                        .setCancelable(false)                        .setPositiveButton("OK", new DialogInterface.OnClickListener() {                            public void onClick(DialogInterface dialog, int id) {                                 //do things                            }                        });                 AlertDialog alert = builder.create();                 alert.show();              }   But I end up with the error: Type mismatch cannot convert from a String to a Boolean.   My question is: What would be the best method of resolving this issue?


Biber/Biblatex suddenly error with citation

Is there a way to easily record a phone conversation in-progress?

I do not own an Android device. I was thinking about getting one, and an important feature for me is the ability to record a phone conversation which is in progress - meaning, while I am in the middle of a conversation, I could touch a button which will save a two-sided audio recording of that conversation from the moment onward.  I am aware that recording a conversation I am participating in without notifying the other members is illegal in some places - I have already checked this and have verified that it is completely legal in my country.  Is there is such a functionality in Android, through core features or available applications?  EDIT:   I prefer a solution which does not notify the other side of the recording, though it's not a must. I need a solution which works in any country.

Integrate $\int_0^{\frac{\pi}{2}}\frac{\sin^3(x)}{\sin^3(x) + \cos^3(x)}dx$

I am quite sure I saw this somewhere on SE but I couldn't find it. How to evaluate $$\int_0^{\frac{\pi}{2}}\frac{\sin^3(x)}{\sin^3(x) + \cos^3(x)}dx$$  I already have  $$\int \frac{\sin^3(x)}{\sin^3(x) + \cos^3(x)}dx+\int\frac{\cos^3(x)}{\sin^3(x) + \cos^3(x)}dx = \frac{\pi}{2}$$  Ideally I would like to have something like $I_1 + I_2 = \frac{\pi}{2}$ and $I_1 - I_2 = \text{something}$. But   $$\int \frac{\sin^3(x)}{\sin^3(x) + \cos^3(x)}dx-\int\frac{\cos^3(x)}{\sin^3(x) + \cos^3(x)}dx=?$$  I tried to play around with even and odd functions' property. The problem is that $\sin^3(-x) + \cos^3(x) = -\sin^3(x) + \cos^3(x)$.

"Table" trying to get a value from the same row with button click

I need to get the value from column RR from the same raw the button is clicked   the problem here is that the code only works when i use evaluate in console in google developer tools  Table :

I have got a car.  Would it be correct to answer:  So have I.  or:  So do I.  Likewise:  I have got three sisters. Reply: So do I. or So have I.  Both responses sound possible to me, but I can't figure out if one would be grammatically incorrect. To me, have got seems like a present perfect construction but I am uncertain. Also, have got seems to be functioning as showing possession of an object.


Why had Peter lived for twelve years as the Weasley family's rat?

As we were told, he only sought out his master because he had no choice. At least, Voldemort thinks so:     “And then, not even a year ago, when I had almost abandoned  hope, it   happened at last... a servant returned to me. Wormtail here, who   had faked his own death to escape justice, was driven out of hiding by   those he had once counted friends, and decided to return to his   master."   GoF,  The Death Eaters   and he's probably right as Peter, once set on finding Voldemort found him in Albania (!)  even before the new school term started.  So we have Peter living at Hogwarts / at the Weasleys why exactly? To gain information from Arthur, who was a ministry employee to do what...?  Wouldn't it be nicer running abroad or polyjuicing himself into someone else or even living as a muggle? Wouldn't it be better than sleep with Percy/Ron and eat leftovers?  What was exactly Peter's plan until he was caught by Sirius? To live his life as a rat?

Find confidence level when sampled Bernoulli trials are all successes

I have many (250) instances of an experiment in which a binary random variable is the output. I selected a sampling of 80 instances and verified the result in every case to be success. I suspect that all 255 instances are success, but I cannot be sure without testing all of them.  Question: Based on testing only these 80 instances, how can I calculate a confidence level that all 250 instances are success? Is this even possible?  I tried using the confidence interval formula for a Bernoulli random variable, but because all instances sampled were success, I came up with the confidence interval (1,1) for any alpha level, which isn't what I'm looking for.  More generally, how do you deal with the situation where all samples are of the same class? The problem isn't that my sample size is too small--it's just that a seemingly large majority of instances (potentially 100%) are successes.

Successful ajax calls but why do I have to update the page?

On the user's profile page he can subscribe to or unsubscribe from a newsletter. I want this to be handled with ajax calls so the site doesn't have to be reloaded. PHP part (to get the email address):     $email = $_SESSION['userId'][0]['email'];     $nls = new \Models\NewsletterModel();     $userIsSubscribed = $nls->getNewsletterEmail($email);     if ($userIsSubscribed[0]['newsletter_verified'] == 0) {          $f3->set('subscribed', false);     elseif ($userIsSubscribed[0]['newsletter_verified'] == 1)          $f3->set('subscribed', true);  HTML part (to show right text in button):             <check if="{{ @subscribed }}">                 <true>                     Unsubscribe From Newsletter                 </true>                 <false>                     Subscribe To Newsletter                 </false>             </check>  JS part with the ajax call:     var userEmail = $.ajax({      url: "/getUserEmail",      success: function (email) {       var userEmail = email;  $.when(userEmail).done(function (email) {   if ($(".newsletter").hasClass("unsubscribed")) {     $(".unsubscribed").click(function () {       $.ajax({         type: "POST",         url: "/newsletter/activate",         data: { json: JSON.stringify(userEmail) },         dataType: "json",         success: function (data) {           $(".newsletter").html("Unsubscribe From Newsletter");           $(".newsletter")             .removeClass("unsubscribed")             .addClass("subscribed");         },       })         .done(function (data) {})         .fail(function (data) {});     });   } else if ($(".newsletter").hasClass("subscribed")) {     $(".subscribed").click(function () {       console.log(userEmail);       $.ajax({         type: "POST",         url: "/newsletter/deactivate",         data: { json: JSON.stringify(userEmail) },         dataType: "json",         success: function (data) {           $(".newsletter").html("Subscribe To Newsletter");           $(".newsletter")             .removeClass("subscribed")             .addClass("unsubscribed");         },       })         .done(function (data) {})         .fail(function (data) {});     });   } });  }, });  Desired outcome: The ajax call for subscribing works fine. The ajax call for unsubscribing works fine aswell, but only if the page got reloaded or the used clicked another route and comes back to the profile page. I don't understand why I cannot "toggle" between subscribe and unsubscribe.


Should I install programs directly into /usr/local or a subdirectory in usr/local or into /opt?

I want to install PHPStorm IDE on my PC. The Linux version is distributed as a .tar.gz archive which contains bin, help, jre64, lib, license and plugin directories and 2 text files.  I have searched around and the place for user-intalled programs is apparently /usr/local or /opt.   Should I install it into /usr/local or /opt? In case that /usr/local was the answer to the first question: /usr/local already contains some directories which are the same as in the PHPStorm archive (bin, lib); should I copy the directories from the archive directly into /usr/local or create a phpstorm subdirectory and put them there?

Should article submissions be formatted in draft format, or in the format of a particular journal?

Some journals do not require article submissions to be in any particular format. Would it still be better to try and copy that journals usual format, or use a generic draft format? Would you as an editor or a reviewer prefer one over the other?  For example, many articles use a two column format that is nice and compact for publication, but is a little harder to review and markup - so maybe the reviewers would prefer the article in a single column draft format?  EDIT: I'm specifically asking about journals that state you can use any format you like (for submission), leaving you free to choose whatever will be most convenient for the editors and reviewers. Do you try and still present a "finished product", i.e. format it like it will be if published - or use larger spacing, etc. to make it convenient for review. What would you as a reviewer or editor prefer in the absence of set submission guidelines. Or would you not care in the slightest?


How are you supposed to write nested if statements in lambda functions?  I'm trying to use a filter function using lambda:  final_list = filter(lambda x: False if isinstance x(float) or isinstance(x, int) if x<5, another_list)   What I'm trying to do is:   Check if the value is float or int If float or int, check if < 5 If < 5, return False so filter will move on to next element of list.   My error says that my nested if x < 5 is invalid syntax.


This fault has only emerged since upgrading from Ubuntu 14.04.4 to 16.04. My laptop is an Acer Aspire E13, Intel Pentium N3540 no graphics card. I am duel booting this laptop, no issues with windows suggesting it is not a hardware issue.  Specifically the fault is a freeze of Ubuntu when using unity with no obvious trigger. Once frozen no response at all can be elicited.  I originally thought this may be a flash problem as I have in the past had similar problems with flash plugins and Ubuntu/other linux distros. However purging and reinstalling does not seem to improve the situation. I have also tried a number of different browsers in an attempt to see if this effects the frequency of the fault, it doesn't seem to. I also attempted turning off hardware acceleration again no fix.  The major issue I have is that the freeze is total, there is no way to move from tty7 (unity) to tty1-6 in an attempt to read the logs and because a forced shutdown is the only way to get a response I can find no record of the fault after restart.  How can I go about debugging this fault? Has anyone seen a similar fault and know the solution?  Thanks in advance

What is it called, when you add a new actionlistener with a method while already in a method?

Just to make sure, this is what I mean:  public static void someMethod() {     JButton btn = new JButton();     btn.addActionListener(new ActionListener()     {         public void actionPerformed(ActionEvent e)         {             // Do something...         }     }); }   So when adding an ActionListener to the button, I create a new ActionListener and a new method inside a method - but what is this implementation of an ActionListener called?

Are there any performance loss and lifespan risk for using NTFS on Linux?

I often use a virtual machine to do something, but virtual hard disks are large and the SSD on my laptop is small. So I bought a 1TB HDD mobile hard drive to store most of my data. By default it is formatted to NTFS, and NTFS also has the best compatibility for Windows.  Since NTFS is not designed for Linux, are there any disadvantages of using NTFS on Linux everyday? Especially when I use virtual disks and have a lot of r/w. If not, what is the best file system choice for it?  I just don't want to reduce its lifespan.


Why did they film a scene for Nemesis with Lt. Wesley Crusher?

In this , Wesley appears at the Riker-Troi wedding in a Lt JG uniform.    Why would this occur?   It's clear from "Journey's End" that       WESLEY: Dad came to me and told me not to follow him. He said I had to find my own path.   And then he resigns from the Academy and goes and studies with .  It seems pretty unlikely that he would change his mind, get readmitted to the Academy, graduate and get promoted to Lt JG (admittedly nine years have passed).  I understand they sometimes have plot holes, but they could have easily filmed him in civilian formalwear.       Was there some intent to open up the possibility of him returning in the future shows or films?


How do I add a custom keybind to a button on any website?

I am doing annotation work and the web interface is not user friendly at all.  I would like to add my own keybinds to buttons like "clear current field" or "switch to a previous field" so I don't have to keep reaching for my mouse every few seconds. Is that possible and how can I do it? I have some HTML background and can identify the element that presses the button on the website, but don't know anything about scripts unfortunately.  It is a third party website. This is how it looks like:    The code for one of the buttons is this:  </button><button onclick="void(0);" class="t-Button " type="button"  id="buttonClearField">Clear Field</button><button onclick="void(0);" class="t-Button " type="button"  id="btnSaveHeaderFields">Save</button>   I want to be able to press a specific keybind (for example ctrl+A) instead of clicking on the buttons every time.   I got it going! I used the code from one of the answers here  and it worked. Yay!

Add, update and edit an XML file with PHP

I have an xml file which I would like to create a form/table around to add, edit and delete records using PHP.  Currently I use simpleXML to load the XML file, and display its content on various pages.  Is there any way I can create a table that shows all results, and allows me to either edit or delete that particular row of the table which represents a full record within the XML file.    When clicking edit I would like the details from the record to appear in a form which the user can change and then save out, updating the XML file and the corresponding web page.  I need this done in PHP, preferably using SimpleXML, though open to suggestions of other ways to do this with PHP.  Cheers


Preserve memory for gui and core OS routines

I'm programming stuff on Python with Pycharm, and sometimes run regressions using Stata.   Sometimes, I need these applications to use as much as memory as they can get to speed up computations/  Sometimes, through nobody's fault but my own, these applications explode in memory. Perhaps a case I didn't think about, some inefficiency in algorythms, there are multiple ways this can happen.  I would like to guarantee these applications as much memory as possible, but prevent them from taking "core applications" memory. That is, I don't want my general Ubuntu GUI (great if this works for Elementary OS, too) to be slowed down because it has to be loaded into memory again.  Is there a way to ensure that a certain set of applications always precede in memory, if they are running? I mostly care about core applications and GUI, but it would be great if I could add custom applications such as Kupfer to the list.


I installed ubuntu by overwriting windows 7. I didnt knew it would delete all my hard disk partitions and data. Now there is only single drive which has ubuntu installed in it. how to recover my lost drives and data? Please help me.


Create a Google Sheets chart with multiple data ranges with separate key columns

I have this data:   X1      Y1      X2     Y2   1      20       1     25   2      20       3     42   3      20       6     50   5      25       8     50  10      30      10     50   I want to create a graph that overlays two lines, one with X1 as X axis, Y1 as Y axis, and one with X2 and Y2.  Values with the same X are meant to line up, so at 3 on the X axis, there's supposed to be 20 for Y1 and 42 for Y2. Just adding two data ranges to the graph won't do that.  My current plan is to create two intermediate data ranges that are basically exploded, so it interpolates the data in each range so there's a value for every single X (see ). But that approach doesn't sound very smart, there must be a better way.


Why don't we include $\rho g h$ in a hydraulic jack below?

Consider a hydraulic jack with massless pistons as follows.    The famous equation for this system is   $$ \frac{F_1}{A_1}=\frac{F_2}{A_2} $$  My question is why isn't the equation as follows?  $$ \frac{F_1}{A_1}=\frac{F_2}{A_2} + \rho g h $$  It is based on  my understanding that any points in the same horizontal line have the same pressure.  Could you spot my misconception?


"people" and "money" previously were used to denote plural. Now we have "peoples" and "moneys". What is the reason for this?


I was taking an online course and saw linear regression being by gradient descent The intuition behind why the method would work seemed plausible.  I tried understanding normal equation as to why setting individual partial derivates to 0 and solving the equations give the optimal values of theta, but that didn't ring a bell.   Why setting partial derivatives to zero, and solving the equations gives optimal value of theta. I also went through the following . The part about The minimum is determined by calculating the partial derivatives of S(β1,β2) with respect to β1 and β2 and setting them to zero is still dicey to me. Why would it work. Why would it give the values of β1 and β2 for minimized cost function. If we have multiple local optima, would the normal equation method give the global optima? If so, why?


I'd like to know do I normalize a URL in python.   For example, If I have a url string like : " goo/bar.html"  I need a library in python that will transform the extra space (or any other non normalized character) to a proper URL.


How to find all rational points on the elliptic curves like $y^2=x^3-2$

Reading the book by Diophantus, one may be led to consider the curves like: $y^2=x^3+1$, $y^2=x^3-1$, $y^2=x^3-2$, the first two of which are easy (after calculating some eight curves to be solved under some certain conditions, one can directly derive the ranks) to be solved, while the last , although simple enough to be solved by some elementary consideration of factorization of algebraic integers, is at present beyond my ability, as my knowledge about the topic is so far limited to some reading of the book Rational Points On Elliptic Curves, by Silverman and Tate, where he did not investigate the case where the polynomial has no visible rational points. By the theorem of Mordell, one can determine its structure of rational points, if the rank is at hand. So, according to my imagination, if some hints about how to compute ranks of elliptic curves of this kind were offered, it would certainly be appreciated. Thanks in advance.


How to determine the Galois correspondence of the extension $\mathbb{Q}(\zeta_{28})/\mathbb{Q}$, where $\zeta_{28}$ is a primitive 28-th root of unity?  It seems that in  only $\mathbb{Q}(\zeta_n)/\mathbb{Q}$ for $n=p^k$ is discussed.


Algebraic proof that if $a>0$ then $1+a^9 \leq \frac{1}{a}+a^{10} $

Prove that if $a>0$ then $1+a^9 \leq \frac{1}{a}+a^{10} $.   Using the fact that $a \gt 0$, multiply by $a$ on both sides and get everything to one side we have; $a^{11}-a^{10}-a+1 \geq 0$. By factoring $(a^{10}-1)(a-1) \geq 0 $.  I am not sure how to proceed any further.


Why won't my follower follow me after the "A Night to Remember" quest line?

At the end of the "A Night to Remember" quest line, my follower came with me when I was teleported to the Misty Grove. Once there, I told my follower to wait.  Now, when I was teleported back to the real world, my follower's not with me: presumably because he's still waiting at the Misty Grove. I've waited for some time and still he hasn't come back.  How can I get my follower back?


Can I change Windows 7 display language on Home Premium version?

My neighbor just bought a Windows 7 laptop. He's from Mexico originally, and he wants to switch it over to use Spanish. Before I even helped him, he was able to switch it over to use a Spanish keyboard, date time format, etc. Internet Explorer defaults to the Spanish version of Google and Bing so it recognizes the system locale as Mexico.  What doesn't happen is the display language change to Spanish. All the menus are English, Start Menu entries are English, and all messages are English.  From what I can tell you have to have Windows 7 Ultimate or Enterprise to use a true multi-lingual interface. It would appear that those versions allow you to download new language packs through Windows Update. Unfortunately he has Windows 7 Home Premium on the laptop.  I saw some references to downloading a LIP(?) (language interface pack) in the Windows 7 help. I followed the links to Microsoft's language site, and it only listed downloads for Windows XP Tablet Edition.  From what I read Windows 7 works similarly to the way Windows Vista does, but I've never tried changing the display language on Windows Vista either.  Where can I legally get a Spanish language download for Windows 7? I found places where I could download a pirated copy of the full MUI for Windows 7, but I'm not willing to go that route.  Is my neighbor just out of luck? Does he need to buy a laptop in Mexico in order to get one he can use?


Can I add my remaining Schengen days to my new 90 days?

I left the Schengen in June after staying 88 days. My 90 days outside the Schengen finishes next month. My question is, the 2 days I have left from the last 180 day period - can I add these together with my new 90 days? Can I go I fx. my embassy after two days and have my passport stamped again while in the Schengen?  Hope the question is clear enough and that someone has a word of advice abou this.   Thank you!

Changing category subject in short intervals

I would like to know if it is possible to not get penalised by google for changing the subject of a category entirely. I would like to swap a category that I have built on a webpage, for one with a more relevant (as of now) topic. Changing description, content and title etc... would this destroy my SEO? It has amassed backlinks of great quantity and quality over the course of time and I seriously would not like to have them wasted or passed with internal links as the page itself is invaluable. Assume anchors to my webpage were all "<empty>" for convenience purposes. They are nothing particularly descriptive.


Let ${W_t}$ be 1 dimension Brownian motion and $X_t:=\exp(t/2)\cos W_t$ $t\in[0,T]$.  Show that $X_t$ is martingale.  I understood $df(t,W_t)=-\exp(t/2)\sin xdW_t$ , but I don't know why it become $X_t=1-\int_0^t \sin X_sdW_s$.  $f(0,X_0)=e^0 \sin X_0=1$? $X_0=?$  Please tell me.


Using entanglement for communication based on the double slit experiment

When we perform a double slit experiment we receive interference pattern. when we measure in a specific slit the exact location of the photon (or electron) the interference pattern disappears and we receive only 2 light spots with no interference pattern.  Now let's assume that we perform the double slit experiment on two entangled photon (or electrons) far away from each other (Alice & Bob).  If Alice measures the location of the photon in the slits, she doesn't receive interference pattern, but because of entanglement the location of Bob's photon is now known and he also doesn't get an interference pattern. This way he knows instantaneously that Alice performed a measurement even when she is far away.  If she doesn't measure the location of the photon in the slits, they will both receive interference pattern and Bob will know instantaneously that she didn't measure the photons location.  This ideas based on the EPR famous paper enables faster than light communication. What did I miss here?


I have to compute $$Z(t)=\sum_{n=1}^\infty e^{-\lambda_nt}$$ with $\lambda_n=\pi^2\left(\frac{m^2}{a^2}+\frac{n^2}{b^2}\right)$. So  $$\sum_{m,n=1}^\infty \exp\left(-\pi^2\left(\frac{m^2}{a^2}+\frac{n^2}{b^2}\right)\right)t=\sum_{m=1}^\infty \exp\left(-\pi^2\left(\frac{m^2}{a^2}\right)t\right)\sum_{n=1}^\infty \exp\left(-\pi^2\left(\frac{n^2}{b^2}\right)t\right)$$  where $a$, $b$ are real constants and $t$ a real variable.  $$e^{-tn^2}\le\int_{n-1}^n e^{-tx^2}\le e^{-t(n-1)^2}$$ and $$e^{-t(n+1)^2}\le\int_{n}^{n+1} e^{-tx^2}\le e^{-t(n)^2}$$  so we obtain $$\int_{n}^{n+1} e^{-tx^2}\le e^{-t(n)^2} \le\int_{n-1}^n e^{-tx^2} \implies \int_{1}^{\infty} e^{-tx^2}\le \sum_{n \geq 1}e^{-t(n)^2} \le\int_{0}^{\infty} e^{-tx^2}$$ However, I cannot find explicitly the value $$\sum_{n=1}^\infty \exp\left(-\pi^2\left(\frac{n^2}{a^2}\right)t\right)$$ However, this does not give me an explicit solution on the convergence of $Z(t)$.  Could anyone could help me on how to compute $\sum_{n=1}^\infty \exp\left(-\pi^2\left(\frac{n^2}{a^2}\right)t\right)$?


I understand in theory how the common modulus attack works (as described here: )  Though, I did not understand completely how it worked with a negative $s_i$. Since $e_bs_1+e_cs_2=1$ one of the $s_i$ will be negative, so when I calculate $C_j^{s_i}$ it will be a fraction and not out of $\mathbb{Z}$.  From what I learned from the comments the trick is to calculate $(C_j^{-s_i})^{-1}=C_j^{s_i}$ instead. That way $-s_i$ is positive and $C_j^{-s_i}$ can be computed easily as well es the inverse $(C_j^{-s_i})^{-1}$ (using the Extended Euclidean algorithm). This solves my problem.  (I edited this question to specify my problem, answer it and to explain how it is different from  in the hope that it won't be marked as duplicate anymore.)

Can you install an app in a secure silo?

So I am learning Chinese and - because Google is not available in China - Chinese apps tend to be downloaded outside of the play store. To that end, a lot of news apps (especially the good ones which are offered by the state news organisations, e.g. CCTV) have ridiculously wide-ranging security-access levels (i.e. you have to agree that they can read your contacts, your accounts, camera access, the works - even though it has no logical need for such access). Obviously, not too keen on giving the Chinese government full access to spy on me for the benefit of a news app, but is there a way of setting up a secure silo within Android, in which you can then install apps and dictate what access they can have?  In some respects, I would like to set up a Great Firewall of Europe on my phone and put the Chinese apps (or at least the ones which seem to come with added surveillance functionality) in there to stop them unnecessarily getting at my contacts etc. Your help would be greatly appreciated!

Let $F$ be a field, show that $(A \setminus C) \setminus (B \setminus C) = (A \setminus B) \setminus C\; \forall A, B, C$ in $F$

Let F be a field, Show that: $$(A \setminus C) \setminus (B \setminus C) = (A \setminus B) \setminus C,$$         $\forall A, B, C \in F$  where \ indicates set minus.   I've started with left hand side and reached this point:  $$(A \cap C^c) \cap (B \cap C^c)^c$$  where ^c is the complement. I don't know where to go from here.


Suppose that $R$ is a commutative ring and $M$ and $N$ are finitely generated $R-$modules. What we can say about $Hom_R (M,N)$? is it a finitely generated $R$-module?


The question is simple: is there any advantage in using sigmoid function in a convolutional neural network? Because every website that talks about CNN uses Relu function.


Assumption of error of logistic regression

I know there are debates about whether the error exists and its distribution in the case of logistic regression.  Suppose we assume that the error term follows the logistic distribution. Are we looking for a set of betas that will make the error term generated accordingly (in the population) satisfy the logistic distribution using maximum likelihood?


Block networks from appearing in the 'Hot Network Questions' list

I see this was asked a couple of times about three years ago and at the time the feature request was apparently denied:        Is this still the case? If so, why? I have precisely zero interest in having certain questions polluting a list that I might actually find useful if I could at least tailor it a bit to my needs.


I can't install or update Apps from Play Store: Error 905. How to fix?

To prove that if a function $f : \mathbb R \to \mathbb R$ is locally increasing at every point then the function is increasing

I am trying to prove that if $f : \mathbb R \to \mathbb R$ is locally increasing at every point , i.e. if for every $x\in \mathbb R , \exists r_x >0$ such that $f(a)\ge f(b) , $ whenever $ x+r_x >a>b>x-r_x $ , then $f$ is increasing everywhere .   I have proceeded as : Let $a,b \in \mathbb R , a<b$ ; we want to show $f(a) \le f(b)$ ; now for each $p \in [a,b]$ , there is an open n.b.d. of $p$ in which $f$ is increasing , so by these open intervals , we get an open cover of $[a,b]$ and since $[a,b]$ is compact we can get a finite subcover ; but then I am stuck ; can the proof be finished in this way ? Or is there any better way ? Please help . Thanks in advance

As a noun, does the word 'laic' operate as a synonym for the word 'layperson'?

Based off of my Internet searches, it is not quite clear to me in what way this word operates.  Collins Dictionary, according to the page at which I looked when I looked up the word 'laic', said that the word 'laic' can operate as a synonym for 'layperson' in a clerical and non-clerical sense; but, according to Oxford Dictionary and some other dictionaries, the word 'laic' only operates as a synonym for 'layperson' in the clerical sense.  For example, would it be correct, if one didn't want to use the word 'layperson', to say: "no, my explaining that sort of thing to you would be an impossibility, as I am a total laic when it comes to this matter".  Can someone please clarify this for me, please?


According to Wikipedia, the  is defined as:  $$Q=2\pi\frac{\mathrm{energy \, \, stored}}{\mathrm{energy \, \,dissipated \, \, per \, \, cycle}}.$$  Here are my questions:   Does the energy dissipated per cycle assume that the amplitude is constant from one cycle to the next. Is it always calculated at the resonance frequency? If the answer to 2 is yes can you explain why for a forced oscillator system with a damping coefficient of $\gamma$ and natural frequency $\omega_o$ the quality factor is $Q=\omega_o/\gamma$ and not some more complicated expression involving the actual resonant frequency (which is not quite $\omega_o$  and is given by $$\omega_r=(\omega_0^2-\frac{\gamma^2}{2})^{\frac{1}{2}}$$ of the system? Is this just an approximation i.e. are we assuming that it resonates at $\omega_o$ but in fact the actual expression is a big more complicated?   Edit: With using the actual value of $\omega_r$ I get: $Q=(\omega_0^2-\frac{\gamma^2}{2})^{\frac{1}{2}}/\gamma$  is this more correct?


I am having Lubuntu 18.04 and want to install miktex, but when I install it shows unmet dependencies because I think it is for Ubuntu 16.04 and 18.04. Is there any way I can install it on Lubuntu?
