In Star Trek Beyond, the Enterprise crashes on a planet inhabited by a murderous faction. Also on this planet the woman Jaylah hides out from this faction. There are several moments in which the antagonists acknowledge knowing about her and even being irritated by her presence.  Jaylah hides out in      what remains of the USS Franklin, a ship lost nearly 200 years earlier with all hands presumed dead. Her hideout is protected by traps and is obscured by some sort of hologram, rendering it invisible.   However, later we learn that      the Franklin's Captain, Mr. Edison, has survived and is now known as Krall, the big bad evil guy. Obviously, he must know where he parked his ship, right?   So, how is it that Jaylah can hide here? Why is rendering her hideout invisible any kind of protection?  I've seen  but I feel this is sufficiently different. I'm not interested in why the antagonist ignored the hideout itself, but why he didn't go looking for Jaylah here.


How to convert portrait to landscape video?

I'm using FFmpeg and I'm aware that it is the fastest offline video and audio converter. Suddenly I've tried to convert portrait videos into landscape but upon checking its Outcome, it changes its aspect ratio and the video become chubby and that is what I don't like at all. I want to convert portrait videos into landscape video that maintains the aspect ratio and its orientation as portrait.


I am trying to write proceeding paper. But I have lines exceeding. How to align the lines exceeding?

He was one of the outstanding geniuses of technology and he obtained patents for more than one thousand inventions including the electric light bulb, the record player and an early type of film projector. He also created the world's first industrial research laboratory.  He was born in Milan, Ohio and he was always an inquisitive boy. By the time he was 10 he had set up a small chemical laboratory in his house after his mother had shown him a science book. He soon became fascinated with electrical currents and it remained the main interest of his life.  In 1869, he borrowed a small amount of money and became a freelance inventor. In the same summer, there was a crisis in the New York financial district called Wall Street when the new telegraphic gold-price indicator broke down. Edison was called in to repair it and he did it so well that he was given a job as supervisor with the Western Union Telegraph Company. They later commissioned him to improve the Wall Street stock ticker that was just coming into use. He did so and produced the Edison Universal Stock Printer, which immediately brought him a fortune of $40,000. With this money, he set up as a manufacturer in order to produce electrical machines.      \begin{equation}  2000000x+30000000000y-6000000000000z=400000000000000 \end{equation} \end{document}


What happens to the shared explained variation in a regression? (Shown with Balentine graph)

So I asked  question and didn't get a response that cleared up my understanding. I came across some material today that provokes my question again in a different context. In some slides I'm going through, the creator included this diagram:  Which was referred to as "Ballentine Graph". If we run the regression $\hat y = \hat \beta_0 + \hat \beta_1 X_1$ Then we'll recover the yellow and brown portion of this graph as $\hat \beta_1$. Similarly for $X_2$. If we run the regression $\hat y = \hat \beta_0 + \hat \beta_1 X_1 + \hat \beta_2 X_2$ then $\hat \beta_1$ will now only be the yellow area. Similar results for $X_2$. My question is, what happens to the brown area when $X_1$ and $X_2$ are both included in the regression? It'd be included in the coefficient recovered if $X_1$ and $X_2$ were included separately but it's not included in either if both regressors are included. Why does brown disappear from both regressors. Where in mathematical space did it go? To me, it seems like $X_1$ and $X_2$ would have to share it but since this isn't the case, did it go into $\hat \beta_0$? Why?


Is there any Sound Equalizer for Ubuntu 17.04

I'm really new in Ubuntu. I never used it before. Any time I face any kind of problem of needing I hit google bar and I get solution from askubuntu.com.  But this time I failed to find solution of equalizer for Ubuntu 17.04  Isn't there any?? :(


I have come across a problem in Durbin, Modern Algebra, that I am not quite convinced of the answer. The question states:       If $\emptyset$ denotes the empty set, what is $\langle\emptyset\rangle$ (in any group $G$)?   I searched for answers to this question for a while and the only one I could find stated:       $\langle\emptyset\rangle = \{e\}$ , the identity element.   I am not quite sure of the logic behind this answer and any hints or explanations would be thoroughly appreciated.

Finding the smallest number $a \geq 0$ such that $a \equiv 7^{83} \bmod 11$.

Find the smallest number $a \geq 0$ such that $a \equiv 7^{83} \bmod 11$.  I know that I am supposed to come to the conclusion $a = 2$, but I don't understand how I reach this conclusion using Fermat's or Euler's theorem. I have the order $83$ to $7$ in $\mathbb{Z}_{11}$, but I don't know what I write as an answer, because writing just $a = 2$ is not enough to show that I have understood how I came to the answer without using a calculator to just calculate that $7^{83} \bmod 11 = 2$.

How to explain dropout regularization in simple terms?

If you have a half page to explain dropout, how would you proceed? Which is the rationale behind this technique?


I am currently designing a GUI that contains a FileSystem in form of a TreeView.  Everytime you rightclick a TreeItem you will get a menu that looks like this:    My Buttons are position like this atm: first Open, then New Directory, New File, Delete and last Upload.  I was wondering if there were any unwritten rules regarding button order, since this doesnt feel quiet right yet...


Does anyone have a good book on Graph Theory that will introduce me to some of the basic concepts without being so filled with terminology that it's hard to read? I have taken an introductory course (that had no book) and I struggled through it but didn't learn what I should have. I am now a graduate student taking a graduate Graph Theory course (again with no book) and would like a book that can help me develop a stronger base of the beginner topics on my own.   I really would like to stress that the more readable the text is the better it will be for me. Also something with a lot of examples.  Thank you!


Regex extracting price or number value from string in JavaScript

How to extract the value -1,234.23 from the following string using JavaScript regex?     "hello-sdvf-1,234.23 23 everybody 4"   should extract      -1,234.23   This regex returns null:  "hello-sdvf-1,234.23 23 everybody 4".match(/-?\d+\.\d+/);   and that one is OK for  "hello-sdvf-134.23 23 everybody 4".match(/-?\d+\.\d+/);   I need to extract numbers with commas, too.

How to get tens of millions of pages indexed by Google bot?

We are currently developing a site that currently has 8 million unique pages that will grow to about 20 million right away, and eventually to about 50 million or more.  Before you criticize... Yes, it provides unique, useful content. We continually process raw data from public records and by doing some data scrubbing, entity rollups, and relationship mapping, we've been able to generate quality content, developing a site that's quite useful and also unique, in part due to the breadth of the data.  It's PR is 0 (new domain, no links), and we're getting spidered at a rate of about 500 pages per day, putting us at about 30,000 pages indexed thus far. At this rate, it would take over 400 years to index all of our data.  I have two questions:   Is the rate of the indexing directly correlated to PR, and by that I mean is it correlated enough that by purchasing an old domain with good PR will get us to a workable indexing rate (in the neighborhood of 100,000 pages per day). Are there any SEO consultants who specialize in aiding the indexing process itself. We're otherwise doing very well with SEO, on-page especially, besides, the competition for our "long-tail" keyword phrases is pretty low, so our success hinges mostly on the number of pages indexed.   Our main competitor has achieved approx 20MM pages indexed in just over one year's time, along with an Alexa 2000-ish ranking.  Noteworthy qualities we have in place:   page download speed is pretty good (250-500 ms) no errors (no 404 or 500 errors when getting spidered) we use Google webmaster tools and login daily friendly URLs in place I'm afraid to submit sitemaps. Some SEO community postings suggest a new site with millions of pages and no PR is suspicious. There is a , too, in order to avoid increased scrutiny (at approx 2:30 in the video).      Clickable site links deliver all pages, no more than four pages deep and typically no more than 250(-ish) internal links on a page. Anchor text for internal links is logical and adds relevance hierarchically to the data on the detail pages. We had previously set the crawl rate to the highest on webmaster tools (only about a page every two seconds, max). I recently turned it back to "let Google decide" which is what is advised.

Unable to boot Ubuntu after updating from Windows 8 to 8.1

I was having Windows 8 and Ubuntu 12.10 (dual-boot) on my laptop. Recently I updated Windows 8 to 8.1. From then on when starting the system I cannot see the grub (directly boots into windows). I should get into setup to boot into Ubuntu which gives me this error  Error: unknown filesystem. grub rescue>   After reading few forums I have found few solutions that let me do this  set prefix=(hd0,gpt7)/boot/grub insmod normal normal   this successfully lets me boot into Ubuntu.  But according to answer, later on typing these commands in terminal would let us get out of that problem from next time.  sudo update-grub (Run this in terminal after getting into Ubuntu) sudo grub-install /dev/sda (Run this in terminal after getting into Ubuntu)   But its not in my case. I still face the same problem as previous. Please someone help me solving this issue.

What is the recommend function for Ridge regression

The following  is an answer for why lm.ridge and glmnet results are different and how to solve that. My question is different since I am asking which functions are more trusted to use because they are giving different results each time when compared with textbook calculation. I am working with ridge regression in R. I have three functions to use which are glmnet or lm.ridge or textbook calculation. I can make the glmnet results as textbook calculation results. p.tmp <- 5 n.tmp <- 30  set.seed(123) X=scale(matrix(rnorm(n.tmp*p.tmp),ncol = p.tmp)) Y=scale(rnorm(n.tmp))  set.seed(123)  ridge.fit.cv <- cv.glmnet(X, Y, alpha = 0, standardize = FALSE, intercept = FALSE) ridge.fit.lambda <- ridge.fit.cv$lambda.1se ridge_mod <- coef(glmnet(X, Y, alpha=0, standardize = FALSE,   lambda = ridge.fit.lambda) )[-1] ############################### ridge.coef.DEF = solve(t(X) %*% X + n.tmp* ridge.fit.lambda * diag(p.tmp)) %*% t(X) %*% Y cbind(glmnet=c(ridge_mod),textbook=c(ridge.coef.DEF), lm.ridge=c(coef( lm.ridge(Y~X - 1, lambda=ridge.fit.lambda))))  The results as follows           glmnet      textbook     lm.ridge X1  3.040157e-04  3.092039e-04  0.009102455 X2  9.805261e-04  9.972422e-04  0.028596273 X3  1.514714e-04  1.540631e-04  0.004855324 X4  1.721871e-04  1.751177e-04  0.004789519 X5 -4.282657e-05 -4.355457e-05 -0.001143931  Or I can also make lm.ridge results as textbook calculation as giving below set.seed(123)  ridge.fit.cv <- cv.glmnet(X, Y, alpha = 0, standardize = FALSE, intercept = FALSE) ridge.fit.lambda <- ridge.fit.cv$lambda.1se ridge_mod <- coef(glmnet(X, Y, alpha=0, standardize = FALSE,   lambda = ridge.fit.lambda) )[-1] ############################### ridge.coef.DEF = solve(t(X) %*% X + ridge.fit.lambda * diag(p.tmp)) %*% t(X) %*% Y cbind(glmnet=c(ridge_mod),textbook=c(ridge.coef.DEF), lm.ridge=c(coef( lm.ridge(Y~X - 1, lambda=ridge.fit.lambda*(30/29)))))  The results as           glmnet     textbook     lm.ridge X1  3.040157e-04  0.008815056  0.008815056 X2  9.805261e-04  0.027715213  0.027715213 X3  1.514714e-04  0.004692398  0.004692398 X4  1.721871e-04  0.004649196  0.004649196 X5 -4.282657e-05 -0.001112091 -0.001112091  My question is which method I should believe because as you notice the results are different. Should I make the text calculation as glmnet or as lm.ridge?

Different solution of numpy.linalg.lstsq

Basically I have an overdetermined linear system of equations Ax=b, I can use numpy.linalg.lstsq to obtain the least square solution to this latter. However, when I multiply both sides of the equation by a weight diagonal matrix F, the least square solution is different while the equations are technically not. Here is a minimal example:  $A=\begin{bmatrix}1&2&3\\1&3&6\\1&6&2\\1&4&5\end{bmatrix}$ $b=\begin{bmatrix}1\\2\\3\\4\end{bmatrix}$ $F=\begin{bmatrix}0.1&0&0&0\\0&1&0&0\\0&0&10&0\\0&0&0&2\end{bmatrix}$  The solution given of numpy.linalg.lstsq to Ax=b is $x=\begin{bmatrix}-1.56643\\0.685315\\0.374126\end{bmatrix}$  The solution given of numpy.linalg.lstsq to FAx=Fb is $x=\begin{bmatrix}-21.46375975\\3.27144095\\2.41928963\end{bmatrix}$  I though about the equations having different weights in the least square, leading to a different solution chosen by the algorithm, but I am not sure if this is the correct reasoning.  The code:  from numpy import array, diag, dot from numpy.linalg import lstsq  A = array([[1, 2, 3], [1, 3, 6], [1, 6, 2], [1, 4, 5]]) b = array([1, 2, 3, 4]).T F = diag([0.1, 1, 10, 2]) print(lstsq(A, b, rcond=None)[0]) #[-1.56643357  0.68531469  0.37412587] print(lstsq(dot(F,A), dot(F,b), rcond=None)[0]) #[-21.46375975   3.27144095   2.41928963]


Did Col. Landa actually recognize Shosanna?

In the first part of Inglourious Basterds, Colonel Landa kills Shosanna's family and she escapes. He is known as the Jew Hunter and never lets any Jews escape him.   Later when he meets her under her assumed name "Emmanuelle", he makes references that suggests that he does recognize her. However the conversation could also have meant nothing.  If he did actually recognize her I find it very strange that he didn't do anything about her.


I know python functions are virtual by default. Let's say I have this:  class Foo:     def __init__(self, args):         do some stuff     def goo():         print "You can overload me"     def roo():         print "You cannot overload me"   I don't want them to be able to do this:  class Aoo(Foo):     def roo():         print "I don't want you to be able to do this"   Is there a way to prevent users from overloading roo()?


Recover Gmail password using Google Apps admin user

Accurately right-aligning text of wildly varying font sizes

I'm trying to right-align pieces of text in separate TikZ nodes. One piece of text is alphabetical and the other is numerical. The numerical text is much larger than the alphabetical text, and I'm finding there is extraneous space to the right of it. As a result, the right alignment is not accurate enough.  Here is a MWE:  % !TEX program = xelatex  \documentclass{book}  \usepackage{tikz} \usepackage{tikzpagenodes} \usetikzlibrary{positioning} \usepackage{fontspec} \setmainfont{Cambria}  \newcommand\hugefont{     \fontsize{200}{220}\selectfont% }  \newcommand\smallfont{     \fontsize{20}{22}\selectfont% }  \begin{document}     \begin{tikzpicture}[remember picture,overlay]%         \node(small) [anchor=north east,fill=green,inner sep=0pt]             at (current page text area.north east) {\smallfont abc};%         \node(big)   [anchor=north east,fill=red,inner sep=0pt,yshift=-10pt]  at (small.south east)                  {\hugefont 123};%         \node(big2)  [anchor=north east,fill=blue,inner sep=0pt,yshift=-10pt] at (big.south east)                    {\hugefont abc};%     \end{tikzpicture} \end{document}   And here is the result:    As you can see, the "123" has a large gap to the right of the "3", so it doesn't align well. The large "abc" is better, though still imperfect.  I'm aware that my font choice of Cambria exacerbates the issue, but even without it the problem persists to a lesser extent.  Is there any way I can accurately right-align this text without resorting to manual xshift values?


Where do commas fit in with regards to a list of inquiring/exclaiming quotations?

If one were to list several exclamatory quotations within a single sentence, where and how do commas fit in?  For instance;    "When children are on my lawn I like to yell, "Get away you mangy kids!", "I'm going to call the police again!", Here comes the garden hose!", "I know where you live!", or something to that effect."  Do the commas belong outside the quotation marks, inside following the exclamation mark, or do they not belong at all?


show that $f(z)+f(z^2)+\cdots + f(z^n)+\cdots$ converges locally uniformly to an analytic function in the unit disk.

If $f(z)$ is analytic in the unit disk and $f(0)=0$, show that $$f(z)+f(z^2)+\cdots+ f(z^n)+\cdots$$ converges locally uniformly to an analytic function in the unit disk.  I am thinking to apply Weierstrass $M$ test for convergence or since all the $f(z^n)$ are analytic in the unit disk, so each of them can be expressed as the taylor series. Then rewriting the series again might work. But I am not sure. Any suggestions!


Notepad++ auto indent html code while writing

How to use Nginx reverse proxy to connect a public server to internal server?

I am currently working on a site that is hosted from a server running in my home. Here is the setup:   Server running ESXi, two virtual machines First virtual machine is connected publicly to the internet under a DDNS. It is running Nginx and will serve to proxy requests from the public internet to the servers that are on internal IP addresses only I am performing a Wordpress installation on the internal server   Here is the Nginx config:  server {     listen 80;     server_name mydomain.com;     location / {         proxy_pass http://192.168.1.23/;     } }  server {     listen 443;     server_name mydomain.com;     location / {         proxy_pass http://192.168.1.23/;     } }   These ports are forwarded on the home network, and that works. Here's the issue - when I try to load the site outside of my home network it seems to be making a redirect to the internal IP address () which is obviously failing, and not what I want it to do.  I want it to proxy all requests through the proxy server, which is set up to access the public internet. Any thoughts as to why this is happening?


Adjust rounded rectangle radii without creating a new one in Photoshop C6

When I create new rounded rectangles, I see the radii and other information in the properties, but after I work on something else and go back to that layer, the information does not show. How do I adjust the radii of the rounded rectangles without deleting and creating a new one?


There is a file which was already committed and pushed to the repo.  Now I want it to be ignored after initialization, which means that everyone can fetch this file from remote but local change will be ignored  unless ones force-add it again and will not be shown in git status.  It is just like an untraced file except it can be fetch from remote.  I have had some try to solve it.   git rm --cache theFile. The file will be removed from repo by this command and can't be fetched any more. So it's NOT the correct answer. git update-index --assume-unchanged theFile. The file will disappear from git status, which is what I need. But it's a local command. Others should call it manually. Also, the git index will change after some command so ones should call it again. It not quiet fit my demand.   Is there a perfect solution?


How can i practice eugenics without getting caught?

I made myself a nice artificial village, however I severely underestimated the number of villagers it would create:    I now have a couple hundred villagers all crammed in this tiny spot here, and as you can see with the hearts, they aren't showing any signs of stopping.  This isn't a bad thing, as I am after that one villager who sells me the coveted 'Mending' enchanted book. There's just one problem: all these other villagers that get in my way and have relatively worthless trades.  For these "lesser" individuals, I could just slay them with my sword, but there are several iron golems who ruthlessly seek revenge as soon as I touch any of them. Turns out not everyone shares my vision of a perfect world with perfect trades.  I could also let them free, but that would be disastrous: I'd never get them back into my jail custom-built house. It'd be like herding cats. And I don't know if you've ever had a villager stuck inside rows of doors, but they open and close them incessantly.  Here's what I'd like to do:   I do not want to accidentally kill any child villagers for any reason, because I want to see their trades once they become adults I do want to kill any villagers with worthless trades at my discretion. I do not want to aggro Iron Golems in any way, because I value my life I do not want to kill Librarians until after I've traded with them enough to see what their second enchanted book is. I also want to keep Farmers, as they are my primary income for emeralds. I am in Survival on Bedrock Edition, so command blocks, cheats, and anything in Creative Mode are off the table.   How can I safely cull villagers who don't offer meaningful trades while preserving those villagers that do?

My Stochastic Analysis notes define the following:  a) $\textit{The stochastic processes X and Y are called a modification of each other if}$ \begin{align} P(X(t) = Y(t)) = 1 \quad \textit{for all t $\in$ I} \end{align}  b) $\textit{The stochastic processes X and Y are called indistinguishable}$ \begin{align} P(X(t) = Y(t) \,\,\,\textit{for all $t \in I$}) = 1 \end{align}  I interpret this to mean that:  (a) for each $t$ in $I$ the probability that the processes are equal is equal to 1.  (b) the probability that the entire path of the processes X is equal to the entire path of the process Y, is equal to 1.  I don't understand the difference between the two statements. The first seems to examine the processes at each point. The second examines the paths of the processes (which are made up of the points!).  Is anyone able to provide a motivational explanation as to why (a) does not mean that the paths are the same? I find it counter intuitive since if the processes are equal at each point then surely their paths are the same?  The classic example I've been given which (apparently) shows the two processes to be a modification and not indistinguishable is:  $\textbf{Example:}$ Let $\Omega = [0,\infty), \mathcal{A} = \mathcal{B}([0,\infty))$ and $P$ be a probability measure on $\mathcal{A}$ which has a density. Define two stochastic processes $(X(t): t \ge 0)$ and $(Y(t): t \ge 0)$ by \begin{align} X(t)(\omega) =  \begin{cases}  1, \text{ if $t = \omega$},\\ 0, \text{ otherwise} \end{cases} \quad Y(t)(\omega) = 0 \quad \text{for all $t \ge 0$ and all $\omega \in \Omega$.} \end{align} Then $X$ and $Y$ are modifications of each other but $X$ and $Y$ are not indistinguishable.   $\textbf{Question:}$ With regard to the example above if $t = 0$ and $\omega = 0$ then $X(0)(0)= 1$ but $Y(0)(0) = 0$, then how can their probability be equal to 1 at this point? Hence how can they be a modification of each other?  Many thanks,  John


Use of named arguments instead of numbers in LaTeX

ConTeXt has a .mkvi file extension for modules (roughly similar to LaTeX packages) which allows to use named arguments like: \def\foo[#parameters]#content{ #parameters ... #content ...}  instead of \def\foo[#1]#2{#1 ... #2 ...}  Not really a difference, but it has an advantage that macros tend to be more readable. Are there any packages or functionalities which allow the same for LaTeX?


Algorithm to dynamically monitor quantiles

I want to estimate the quantile of some data. The data are so huge that they can not be accommodated in the memory. And data are not static, new data keep coming. Does anyone know any algorithm to monitor the quantiles of the data observed so far with very limited memory and computation? I find  useful, but it does not work very well for my data, which are extremely heavy-tailed distributed.


How to know default software version for all Ubuntu software for a specific Ubuntu version?

The  version in Ubuntu 14.04 LTS is 1.12.1, but the latest Wireshark version is 2.6.0. The default php version is 5 but the latest php version is 7. The sudo apt-get install command easily installs software, but sometimes it provides old versions. So, if I can know the default version provided by a particular software package in a newer Ubuntu release, I can make a decision whether to upgrade my Ubuntu version or not. Is there any Ubuntu release note/doc/chart that lists default software version for all Ubuntu software?


Launchctl:Dubious permissions on file: Problem Installing Jenkins

I'm trying to install Jenkins on 10.6.8 and part of this requires that modify the plist launch daemon.  org.jenkins-ci.plist   which is owned by root.  I was using admin and I gave admin permission to write this file. I used this permission to make the admin the jenkins user and set the home directory to be the admin user directory.  However now I cannot run the launch daemon.  launchctl: Dubious permissions on file (skipping)   Now I realize this is due to a security issue with having given myself this permission.  The plist now has my admin user as the user for jenkins.  Should I now just remove the write privileges and all is good (admin can now be the jenkins user) or not?  Update: I did sudo chown root org.jenkins-ci.plist and it still feels things are dubious.

I don't  know much about electricity.    In my kitchen there are 3 GFCI receptacles. There was a kettle plugged into one and the microwave. The fridge was on the other.  Both outlets quit last night when I opened the fridge, but the breaker didn't trip.   The reset buttons won't do anything, the green light at the bottom of the receptacle is off (on these GFCIs the light is on when they have power).   Every other outlet on this circuit is working, including the other GFCIs.    Any ideas what happened here?   Should I replace the GFCI outlets?

How to insert an image that also acts as a link

Can an image be included in TeX so that the resulting PDF is clickable leading to a reference?


After upgrading from Ubuntu 18.10 to 19.04, Gnome has upgraded from 3.30.2 to 3.32.0. My handy desktop icons, links, and mounted volume icons are gone, the Desktop tweaks are gone to bring them back, and the Desktop shortcut is gone in the sidebar of Nautilus (Files). The actual files and Desktop are still there when you navigate under Home obviously, but this makes them so inconvenient to get to or use.  I found and installed the Gnome extension called Desktop Icons and that works...but not well. They're difficult to size, sort, and arrange. And they used to be clickable on top of or through my Conky stuff. Now they are below Conky and I cannot click on them. So it really renders Conky unusable for me. I have to turn off Conky to use my desktop icons. I really want the old Gnome desktop back.   I realize it's too late or extremely difficult to go back to Ubuntu 18.10 at this point. Can I stay on 19.04 and revert back to Gnome 3.30.2? If so, how?

How can I partition out damaged sectors on a HDD?

So the idea I had is that I want to create a partition with only or at least all the damaged sectors on a HDD (if only damaged sectors are not possible, then a few normal ones are ok as well) and the main partition would be the undamaged sectors.  Is such a thing possible to do? I can't imagine why not.

Returning an int in the main function of C

I learned that in C++, int main() can be left without a return-statement, at which point it defaults to returning 0. I am wondering if this is also true in C? Would the program cause an error if the function definition is int main(), but its body doesn't contain a return statement?

Consequences of a fixed point of a bounded, complex analytic function

Let $G$ be an open and bounded region of $\mathbb{C}$, and let $f$ be analytic on $G$ so that $f(G) \subset G$ and, for some $a\in G$, $f(a) = a$ and $|f'(a)| = r$. (a) If $r < 1$, then $f^n \to a$, ($f^n$ converges to the constant function $a$ in the space of analytic functions) where $f^n := f\circ f\circ \cdots f$ ($n$-times) (b) If $f'(a) = 1$, then $f(z) = z$ for all $z \in G$.  For part (a), I have done the following: the family $\{f^n\}$ is normal by Montel's theorem, so for any subsequence $\{f^{n_k}\}$ there is a subsequence $\{f^{n_{k_s}}\}$ which converges to some analytic function $g$. Further, we know that $(f^n)'(a) = (f')^n(a) = r^n \to 0$ as $n \to \infty$.  Beyond that, I'm stuck. For part (b), I'm thinking that it is sufficient to prove the statement for when $a = 0 \in G$, and to show that the Taylor series for $f(z) - z$ must be identically 0.  But I'm also stuck here.

I'm a Psychology Major intending to take University level Statistics starting in the Fall.   As I'm a mature student, I've been out of school for about 7 years, and it's been at least that long since I've done any Math related work at any level.  I'm wondering if anyone can suggest some decent books that would be an appropriate primer for someone re-entering Math from a Social Science standpoint? Basically, I'm looking for something to give me a head start on getting back into Math after such a long time away from it, in hopes of not failing my Statistics courses ^^;  Thanks!


Why is $R\cos{a} = mg$ in circular motion compared and not $R = mg\cos{a}$?

Normally, if an object of mass $m$ is inclined to the horizontal at an angle $b$, we set the reaction force of the object on the inclined plane as $R = mg\cos{b}$ (if we resolve the force of gravity so the line of action coming out of the plane is perpendicular to it).  However in circular motion*. it's assumed that $R\cos{b} = mg$. In the example above, one would have to do this in order to arrive to the correct answer, instead of $R = mg\cos{b}$. Using $R = mg\cos{b}$ seems natural enough, as I am resolving vertically, however, both equations would produce two different values for $R$. Why is this?   To show what I mean: If we set the reaction force in this question as $mg\cos{a}$, then the centripetal force will be $mg\cos{b}\cos(\pi/2-b) = mg\cos{b}\sin{b} = \frac{1}{2}mg\sin(2b)$   Whereas If we use $R\cos{b} = mg$, $R = mg\sec{b}$ and the centripetal force will be $mg\sec{b}\sin{b} = mg\tan{b}$. This will end up with two different values for the radius of the circular motion, and hence two different final answers.  *In the circular motion questions I've seen in my mechanics module


How to download El Capitan installer from a High Sierra Mac

My mom's iMac is having issues (it's booting to the "prohibited" circle with a slash), and needs the OS reinstalled. She'd been running El Capitan, and I'd like to reinstall the same since she has some apps that could be incompatible with a newer OS.  Her rural internet is abysmal (think dial-up speeds) and there is no way she'll finish a full download of an OS from her home, so I am intending to create a bootable install disk for her. But when I try to download the El Capitan installer it does not allow me to even begin the download since my computers are all 2018 systems running High Sierra.  Is there any way to download a copy of El Capitan from a High Sierra Mac?

How can i do a "Crouch" with only a Character Controller with no rigidbody?

I was following Bracky's fps tutorial but he didn't add crouching as an option. I took a stab at it but came up empty handed. Here is my script for player movement. public class PlayerMovment : MonoBehaviour { public CharacterController controller; public float speed = 12f; public float gravity = -9.81f; public float jumpHeight = 3f;  public Transform groundCheck; public float groundDistance = 0.4f; public LayerMask groundMask;  Vector3 velocity; bool isGrounded;  // Update is called once per frame void Update() {     isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);      if(isGrounded && velocity.y < 0)     {         velocity.y = -2f;     }      float x = Input.GetAxis("Horizontal");     float z = Input.GetAxis("Vertical");      Vector3 move = transform.right * x + transform.forward * z;      controller.Move(move * speed * Time.deltaTime);      if(Input.GetButtonDown("Jump") && isGrounded)     {         velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);     }      velocity.y += gravity * Time.deltaTime;      controller.Move(velocity * Time.deltaTime); }  And also have a separate script for mouselook, here that is aswell. public class Mouselook : MonoBehaviour { public float mouseSensitivity = 100f;  public Transform playerBody;  float xRotation = 0f;  // Start is called before the first frame update void Start() {     Cursor.lockState = CursorLockMode.Locked; }  // Update is called once per frame void Update() {     float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;     float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;      xRotation -= mouseY;     xRotation = Mathf.Clamp(xRotation, -90f, 90f);      transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);     playerBody.Rotate(Vector3.up * mouseX); }  } How would I go about adding one without adding a rigidbody or changing my script fully to follow other tutorials? Thank you!

My blog which gets 300+ daily impressions has stopped appearing on the 1st page of Google

I have a blog regarding Placement papers from December 2010. My monthly impressions are around 4000. For the last 2 days, my blog has disappeared from Google search engine result pages.  Impressions have reduced drastically.  Please check Stat reports:    My blog is still on the search engine because when I search site: mydomain.com on Google, I can see my all pages indexed over there…  But my pages which used to appear on the first or second pages of Google do not appear any more.  Example: If I search with query GE round 2 code writing test on bing.com or Yahoo search, the first link on the result page is my blog.  But if you do same on Google, my URLs do not appear even on the 1st 3 result pages. I used to get lots of visitors by these search query earlier.

How are straight razor throat slit scenes done?

I am watching Midsomer Murders season 1 episode 3, “Death of a Hollow Man”.  In it, the first killing happens during a stage play. A character in the play slits his throat. This kills the actor because safety tape was not covering the blade of an actual straight razor. This is, of course, ludicrous. It must be a clumsy conceit of that episode’s writer. In real life, no production of theater or tv or movies in the UK or US or elsewhere would ever use an actual straight razor as a prop by simply covering it with tape, especially for a throat slit scene. Right? This made me wonder how straight razor throat slit scenes are really done in movies and TV. What I’m especially curious about is how the actor getting their throat cut makes sure the prop is fake? Do they look closely just before action? Can they determine it is fake by looking at it? Is there an industry protocol for this situation? I suppose one way is to film a close up of a silicon sculpture getting its throat cut edited in with another scene showing a blunt prop razor for the full shot. But surely someone has filmed a full shot of throat slit scene? Probably using a prop that releases fake blood? Or maybe that’s not how it’s done?

Why does virtualbox show only 32 bit option on 64 bit machine and 32 bit os doesn't work

I have a 64 bit AMD computer and was trying to install Virtualbox. However there were only 32 bit options for creating virtual machines. I googled a fix and it said to disable Hyper-v and enable virtualization. I went to windows features to disable hyper-v, but it was already disabled. But as for the virtualization, I couldn't find it in the BIOS anywhere. How would I enable virtualization?


Is it okay if I don't accept an answer even though the answer is correct?

For example: I have a question that I posted before.   It didn't get much attention from other users.  I put a bounty on my question. Many users viewed my question and someone gave me a solution. I reviewed their code.   I thought, "Hmm this is good, but maybe I will wait for another answer." I didn't accept the answer nor reward the bounty (but I did upvote their answer). A few days later, another user gave me another solution. It looks better than the previous one. "Hmm, this is good, but maybe I should wait for another answers." (I upvoted it, though).   Then about 5 answers appeared and the day came where the bounty was about to end. Finally, I choose to accept the answer that matched with my opinion of "correct".   The question is, can I do this just like that?


What do PCs roll Insight against when another PC is trying to convince them that he is telling the truth?

There is already , however the answers focus on that you should not tell players that they don't believe the other but they should decided that themselves and only get hints. And while that may be true for NPCs, for PCs the player trying to convince others of his truthful statement should get to roll something in my opinion. I started to talk about it in the comments of the first answer but the discussion is too extended for comments. So here a new question.   In my specific case I DM a game and I have a new player character X joining the party and he wants to help the party and tells them the town master is actually bad (he has extra information from his backstory). The party has no reason to believe him. They ask for an insight check or whether they believe him. What does the player of X roll in order to convince the other players that he is telling the truth?   X is a charismatic character and I want him to be able to take advantage of that maybe via persuasion. But I don't just want to contest the party insight with his persuasion, because I feel like a high role on either side should be rewarded by, on one hand X showing signs of being truthful, and on the other hand the party reading those signs. I was thinking about adding both checks and taking an average against DC 10 but it seems a bit random.   So a good answer should fulfill the following criteria:   Player X should have a reward for his high charisma score.  The outcome should not be predictable.

I'm a beginner in java, and I was wondering why java actually allows an abstract class to have a constructor if It is not allowed to have an object? Where as in interface it is not allowed.  Thanks in advance!


How do I know the sign convention for $W$ and $Q$ in thermodynamics?

Can someone correct me if I am wrong.  For example,  43 kJ work energy has been done on the system, sign convention is +43kJ, because work is entering into the system  62 kJ work energy has been generated from the system, sign convention is -62kJ, because work is entering out of the system  21 kJ of heat energy supplied to the system from its surroundings, sign convention is +21kJ, because heat energy is entering into the system.  I apologize for my unclear phrasing. The actual question is here:   I got mixed up with the sign convention.


A question about using the "v-ing" verbs

To native speakers, normally do you use adverbs to modify these v-ing worlds especially when they are the objects of the verbs?  Like:      I regret swimming hurriedly     Not      I regret hurried swimming.      Right? And what about these two sentences:     I regret stamp-collecting     or     I regret collecting stamps   Besides, when using these words, it still retains the verbal characteristics right? Like:       The house needs a careful cleaning.     has the same meaning with       The house needs carefully cleaning.     or       The house needs to be cleaned carefully.   (SOMETHING like passive voice)


How do I prove that a graph is a topological manifold

I'm having problems with that:  Prove that M is a topological manifold.  $f:U \to \mathbb R^k$, U $\subset \mathbb R^{n}$ open, f continuous  M = $\{\left(x,y\right)\in \mathbb R^{n+k} \mid x \in U, y=f(x) \}$  Can anyone help me please?


Can we query the info from "Data Management -> Storage Usage" through SOAP API? If so how? Actually, I need the count of records in all the objects in the org, and the size. (Also would like to know how the size [in KBs] is calculated for a record ?)  **Edited**  Am actually looking for something like this :- Like for ex (C# code) :-  String[] SOQLS;  SOQLS[1] = "Select count(id) from accounts";  SOQLS[2] = "Select count(id) from contacts";  QueryResult[] qrarray = binding.query(SOQLS[]);  would I be able do something like this so that i can pull the count of all the objects through api (partner wsdl)?


My players obtained a , which grants them this  You have advantage on Saving Throws against spell and other magical effects.  What qualifies as a magical effect? Is it only effects of spells? What about those of magical items?  : The creature must make a DC 17 Constitution saving throw, taking an extra 6d10 piercing damage on a failed save, or half as much extra damage on a successful one.  Or abilities of creatures, like ?  Frightful Presence: Each creature must succeed on a DC 21 Wisdom saving throw or become Frightened for 1 minute. Fire Breath: Each creature in that area must make a DC 24 Dexterity saving throw, taking 91 (26d6) fire damage on a failed save, or half as much damage on a successful one.  Or effects of potions?  : If you drink it, you take 3d6 poison damage, and you must succeed on a DC 13 Constitution saving throw or be Poisoned.  Related:


I am flying to another state for a visa interview and am leaving my passport there, how can I fly back?

I am flying in 10 days to another state to apply for a travel visa. As a foreigner, my passport is the only ID I have at the moment. How will I be able to travel back to my current state?  Will a photocopy of my passport and American visa, perhaps a letter, driver's license, and/or a temporary state ID work? (I don't think I will be able to get my state ID in time!)


Can I compile an addin developed in ArcGIS 10.3.1 for use with 10.1 and 10.2?

I made an update to one of my addins mainly because users requested new features. I made the changes and compiled the addin in 10.3.1. Although I specified that the addin is compatible with 10.3 and higher I am getting emails from users wondering if I could make it work for 10.2.    ESRI provides a way to save Map Documents for downward compatibility.  Is there a way to compile an addin developed in ArcGIS 10.3 for use with legacy versions (10.1, 10.2)  Note: my ArcObject references are set to non specific version (Specific Version = False)


product of square of two independent variables

If $X$ and $Y$ are independent,    can we assume $X^2$ and $Y^2$ are independent in general? can we assume $X^2$ and $Y^2$ are independent if  $X$ and $Y$ are also identically distributed (in addition to being independent)? can we assume $X^2$ and $Y^2$ are independent if both $X$ and $Y$ (which are assumed independent) followed the normal distribution (not necessarily identically distributed)? can we assume $X^2$ and $Y^2$ are independent if both $X$ and $Y$ followed the normal distribution with identical mean and variance (in addition to being independent)?


I am going to cut some potatoes tonight for a dish I am going to make tomorrow. Will keeping the cut pieces in water immediately after cutting preserve them? There are suggestions at other websites that say adding some lime juice to the water will help. Has anyone had experience preserving potatoes?


Resize multiple layers around their respective anchor points

I have 50 or so layers (imported images as smart objects) that I would like to scale down, while they stay in place. Is there a way of doing this? I know After Effects has, is there a similar Scale property in photoshop?


I wrote a code in AS3 which allowed me to check if a particular number of things were true...  If (true + false + true + true + false + true + true < 4) {  }   When i tried rewriting in C#, it tells me i cannot add type bool and bool. Is the best way of doing this to rewrite it like this? Or is there some simpler work around?  If ((true?1:0) + (false?1:0) + (true?1:0) + (true?1:0) + (false?1:0) + (true?1:0) + (true?1:0) < 4) {  }


I am currently using various live Linux versions.  In most cases I have the choice between a 64 bit and 32 bit versions.  Does 32 bit have any disadvantages other than slightly lower performance?  What about available software, drivers etc?  Which versions are generally best supported?  One of the machines I might use them on is a 32bit, so those distros are a bit more flexible for me.  Also, if footprint is a bit smaller on a 32bit, there is less data to move from a Live USB etc.  Mainly Mint and Ubuntu for now, but availability of packages are quite important. (Especially system tools)


In the old navigation, I could search JavaScript questions while excluding jQuery like this:  [javascript] -[jquery]   This doesn't work in the new navigation.  Could this functionality be added?

How is the action for a point particle defined in general relativity?

In classical physics, the action $S$ is defined as the time integral of the Lagrangian $L$, i.e. $$ S = \int_{t_0}^{t_1} L\, dt. $$ What is the relation between the action, for a point particle, and the Lagrangian in general relativity? If we integrate $L$, do we integrate it over the time $t$ as measured by some observer, the proper time $\tau$, or can we even use any parameter $\lambda$ that is used to parameterize the worldline(s) of the object(s) in the system?


Why is current density a vector quantity while current is scalar?

Electric current is considered to be a scalar quantity because it does not follow the rules of vector addition. Then, why is current density called a vector quantity as it is just current/area ?


console.log(array) returns empty, but console.log(array.length) doesn't return 0

I have the following javascript   var filtered = [];  $('#footballCheck').on('change', function() {   if ($('#footballCheck').is(':checked')) {     for (var i = 0; i < fa_names.length; i++) {       if (fa_names[i]["facility_activity"].toLowerCase().indexOf("football") >= 0) {         filtered.push(fa_names[i]);       }     }      filtered.sort(SortByName);     $('#mCSB_1_container').empty(".facility-name");     for (var k = 0; k < filtered.length; k++) {       $('#mCSB_1_container').append('
\                                              <button class="btn btn-default btn-fill btn-menu" date-name="' + filtered[k]["facility_name"] + '">' + filtered[k]["facility_name"] + '</button>
');       $('#facilities-body').mCustomScrollbar("update");     }   } else {     for (var j = 0; j < filtered.length; j++) {       if (filtered[j]["facility_activity"].toLowerCase().indexOf("football") >= 0) {         delete filtered[j];       }     }     console.log(filtered);     console.log(filtered.length);     if (filtered.length > 0) {       filtered.sort(SortByName);       $('#mCSB_1_container').empty(".facility-name");       for (var k = 0; k < filtered.length; k++) {         $('#mCSB_1_container').append('

Background: The checkboxes act as filters for a search and the filtered array stores those filtered values (in no other place other than what is in that fiddle the filtered array is changed yet).  My problem is that console.log(filtered) returns [] and console.log(filtered.length) does NOT return 0 and it should. Why does this happen and how can I fix it?


Is self signed certificate generated in Sandbox environment available on Production too?

I have generated a self-signed certificate on Sandbox environment and based on that have a JWT token that would be sent to my API being called from Salesforce on some action. Now since I am using the public key for decrypting the JWT token in my  application to authorize the call from SF, I need to hard-code that public key in my api code.   This same api would be called on PROD env too. So my concern over here is that if I create a self-signed certificate in Sandbox env, will it be available on PROD as well?


Comparing the value of readline() to a string

I am reading the inputstream using readline() method and then trying to compare it.  The code is as follows:  //socket is defined before this InputStream is = socket.getInputStream();  br = new BufferedReader(new InputStreamReader(is));  Line = br.readLine();      if (Line  == "hey") {         Log.d("watsapp client tag", "message pushed !!");         Log.d("watsapp client tag", "" + Line);       }    else {          Log.d("watsapp client tag", "message not pushed");         Log.d("watsapp client tag", "" + Line);      }   The above code always executes the else part. although first value of the input stream is "hey" and second is not. So I am expecting in the logcat "message pushed !!" and "message not pushed" instead I get both "message not pushed"  05-31 14:46:14.309    6138-6151/? D/watsapp client tag﹕ message not pushed 05-31 14:46:14.309    6138-6151/? D/watsapp client tag﹕ hey 05-31 14:46:14.339    6138-6151/? D/watsapp client tag﹕ message not pushed 05-31 14:46:14.339    6138-6151/? D/watsapp client tag﹕ <Messageadded:1112/>   Please can tell what is going wrong at line if (Line  == "hey"). Thanks!

Why do planets revolve around Sun in elliptical orbits?

Let’s consider two planets of mass $m$ and $M$. They both will attract one another with a constant force $F$ according to the law of attraction $F=G m M/r^2$. The force and masses are constant. $G$ is also constant. So therefore the distance between them would also be constant. If this distance will be assumed as a radius then the orbit formed will be a circle. So why is it elliptical?


macOS Mojave won't install updates past 10.14.1 due to requirement for APFS formatting

I have a MBP 2012 I upgraded from High Sierra to Mojave after it came out as GA. I don't recall if I was asked about upgrading to APFS when Id id that, but at this time the main volume is Mac OS Extended (Journaled).  My current About This Mac...version is Mojave 10.14.1 (18B75). Now, when updates are advertised from the App Store, I'm unable to upgrade because 10.14.3 is required.  No OS updates show in the App Store, and when I searched for the updaters (10.14.2 Combo, etc), I can't install because the installer reports "macOS 10.14.2 Update can't be installed on this disk. This Mac can only install macOS on APFS-formatted drives."  I tried the search results recommending to boot in Recovery Mode and use Disk Utility, but APFS is not available as a type.  I have good backups and I can reformat the boot volume if I need to, but I have not done this before. Should I get a 10.14.3 installer to do this and boot from an external drive? The only guies and message boards I've found just keep saying to install 10.14.3 (I can't) or convert the disk in Recovery Mode (APFS is not available as an option.)  Any known-good ways to get my 10.14.1 upgraded so I can keep getting App Store updates?


How does Force translate a body if each molecule if pulled with a force,pulls the next molecule and still the body moves?

In diagram 1,F pulls the body. The molecule in contact with F gives an equal normal reaction opposite to F,the same happens with each molecule,how does the body move then?    In diagram 2, is the logic correct that 10 cm part is pulled by 24N so every molecule in contact will be pulled by 24 N that’s why it applies force of 24N on 20cm part?

Can a ship jump to warp from inside an atmosphere

Simple enough question, but I really have only seen the newer Star Trek series and I have not seen a ship go to warp from inside an atmosphere of a planet.                                        The Warp Drive does not produce momentum - it literally warps space   around the ship, dragging the ship and its adjacent bubble of normal   space, through the time-space medium.   Being that I am not up to date on the whole in-universe physics of what happens when a ship goes to warp, I was interested to know what happens if the ship tries to jump to warp from inside an atmosphere.   So can a ship jump to warp from inside an atmosphere?


Is It Possible To Make Matchmaking System Without Server?

I want to make a matchmaking system without a server, but I don't know much about matchmaking. First, let me list what I want to do:   Cheating is not important in the game, so that the architecture will be listen-server. (One of the clients in the lobby will be host.) The players will be connected to each other by sending invitations. I will not list any lobbies in the game. All the data in the game will be sent via RPC functions. (I have already coded this.)   The game will be published on mobile platforms. I wonder if I can connect 2 players to each other in the game without a server. Is that possible? Can I make this kind of system by using a library like socket.io?


Changing/postponing itineraries after visa issued?

I have Indian passport and currently residing in US. I still haven't given my visa interview at French embassy but I have a rough idea about my itinerary. I plan to visit France twice in the next couple of months strictly for tourism and meeting friends (total duration less than 30 days). I will be staying and traveling mostly in France. Maybe a few days to other Schengen countries that I have not figured yet.  While booking the visa interview date I selected the itinerary and got documents (the airline ticket, medical insurance, hotel stay) for the date ranges (for 2 separate trips) that seemed best at the time although now I feel I should've selected something in the future.   Unfortunately, there's no way to "Update" the travel dates in my visa application online and I will have to cancel my application and book another appointment even later and forfeit my air tickets (that I booked to go to the consulate) etc etc. So the plan is to give the visa interview with the itineraries presented at the moment and try to follow them the best I can as I don't intend to violate any rules. Other posts that I read related to this:   . This does not help me much as my question is not about which country I will spend most time in or enter through, but about changing the travel dates itself.  The question I have is what happens if the itinerary is changed? If I take one trip but don't take the other do they care (as long as I stay mostly in France)? If I throw in some other Schengen countries that I had not stated in the travel itinerary and remove some others does that make a difference? Do they keep a record of my movements and any deviation is noted (at the borders etc)? And some posts say "if found it can affect your future visas". Does this mean once I present them with the itinerary it's set in stone? Will changing itineraries have negative impact on current/future schengen visas?  It seems like a catch 22 situation where the embassy themselves state "don't buy tickets just book them because you don't know if visa will be issued", which means I cannot buy (cheap) tickets ahead of time and plan itineraries in advance (cheap hotel bookings in advance) and then I shouldn't be changing them once I get the visa?


Why cant Public Key Encryption be perfectly secure?

I would be very grateful for any help. I cant figure out why (probabilistic) public key encryption schemes can never provide perfect secrecy? Any Ideas?  Excerpt: In contrast to the private-key setting, perfectly-secret public-key encryption does not exist. (We stress that this holds regardless of how long the keys are and how short the message is.) In fact, given pk and a ciphertext c computed via c ← Enc_pk(m), it is possible for an unbounded adversary to determine the message m with probability 1.  (See comments for why this is not a duplicate.)

Mathematical rigorous introduction to solid state physics

I am looking for a good mathematical rigorous introduction to solid state physics. The style and level for this solid state physics book should be comparable to Abraham Marsdens Foundations of mechanics or Arnols mechanics book for classical mechanics or to Thirrings Physics course for quantum mechanics.   Any recommendations?  Edit: As a reaction to Peter Shor's comment, I try to narrow the scope of the question a bit and give some more specific subareas of solid state physics I am in particular interested in:   semiconductors and applications the quantum hall effect superconductivity

Recently, I have been studying autoencoders. If I understood correctly, an autoencoder is a neural network where the input layer is identical to the output layer. So, the neural network tries to predict the output using the input as golden standard.  What is the usefulness of this model? What are the benefits of trying to reconstruct some output elements, making them as equal as possible to the input elements? Why should one use all this machinery to get to the same starting point?

I am just wondering how can I make the color whiter but also metal-like. the car model should have a white-painted metal shell. But I cannot make the color look like white. Although I put white color in there, it looks silver-like. Can anyone help me out to make this look like white-painted metal shell? Thanks.


Cannot tunnel over ssh without command/getting shell

I would like using ssh tunneling options. For that purpose I use command:  ssh -L 1234:localhost:5678 host   however this logs me into the shell on remote host. Next I tried -f as:   ssh -f -L 8999:localhost:6006 host   but I get error Cannot fork into background without a command to execute.  How can I get only ssh tunneling capabilities and running it in background without unnecessary clutter. My ssh version is OpenSSH_7.2p2, OpenSSL 1.0.2h  3 May 2016


Suppose R is a commutative ring, $A \in R_n$, and the homomorphism $f: R^n \to R^n$ defined by $f(b) = Ab$ is surjective. Show $f$ is an isomorphism.

How would I go about showing this?  Suppose $R$ is a commutative ring, $A \in R_n$, and the homomorphism $f: R^n \to R^n$ defined by $f(b) = Ab$ is surjective. Show $f$ is an isomorphism.  (Edit: $R_n$ is the ring of $n\times n$ matrices.)  I'm thinking that since $f$ is surjective on $R^n \to R^n$, for every $x \in R^n$, $x = Ab$, so that $f^{-1}(x) = A^{-1}x$. And since the inverse of any element in a ring is nonzero, $\ker(f) = 0$.  I'm not terribly confident with my answer though. Thanks!


Can a wine program access files outside of the virtual C: drive?

I have to run a program that I don't really trust and I afraid that it may mess up my computer. It is a Windows program so I have to run it in Wine, but I don't want it to access anything outside the virtual C drive. Is it possible somehow?


We're using a custom preference center. Within the Cloudpage Landingpage I want to add a button to optout. I do understand I need to use the LogUnsubEvent function () to unsubscribe.  I'm just not sure how to generate the needed JobId to pass to the function, when the click does not come from an actual email but from a landingpage button, which doesn't have a jobId?

What are the reasons that the `FavoriteCount` column in the `Posts` table has elements that are not available?

I was taking a look at this post which details the database schema for the Stack Exchange Data Explorer. I had one question about the Posts data set: what are the reasons that the FavoriteCount column has elements that are not available?   At first, I thought that this could be completely explained by the PostTypeId column--after all, if the post wasn't a question, it can't be favorited. However, I noticed that there are some questions that have a NA value, even though they're questions. Why is this?


I'm not looking for a proof, but rather an explanation, because I know there's something wrong with my thinking. So, I know that $$ e = \lim_{n\to\infty} (1+\dfrac{1}{n})^n $$ And also $$ e = \sum_{k=0}^{\infty} \dfrac{1}{k!} $$ And I'm confused as to why $e$ can be irrational, since both of those definitions are a rational number(?). I know that addition under rationals is closed, so I'm confused as both of these can be rearranged to something with rationals (e.g. sum of rationals, or $(\dfrac{n+1}{n})^n$), so I guess my question is, is why these rationals converge to an irrational? Thanks.


If I understand correctly, the bug allows to read in another process's virtual address space. To exploit this, the adversary needs to have a legal account on your personal computer, which is not usually the case on a personal home computer, or there must be some malware on the computer, which is bad anyway. Right?


Fallacy of affirming the conclusion question

I'm a little unsure about the exact reason why/when you get "fallacy of affirming the conclusion"   In this simple example:   $$p\rightarrow q $$ $$q$$ $$----$$ $$\therefore p$$  Not exactly sure how I would format that but anyways,  for the argument to be valid if $p \rightarrow q$ and $q$ are both true then $p$ must also be true. Is it an invalid statement because if $p$ is false and $q$ is true then $p \rightarrow q$ is true therefore, the fact that $p$ can be either false or true instead of it needing to be true makes it invalid?   Also, could someone explain to me why   $$p \rightarrow (q \rightarrow r)$$ $$q \rightarrow (p \rightarrow r)$$ $$-------$$ $$\therefore (p \vee q) \rightarrow r$$  is an invalid statement?


Can´t center the p element when it has a background-color with a set width

I´m having trouble automatically centering the p element without the use of margin-left. The body element is center aligned but since there is a background color on the p element it doesn´t work on it...       p {       background-color: dimGray;       width:250px;       margin-left: 630px;            }          h3 {       margin: 20px;     }          h1 {       margin-top: 30px     }          a {       color: red;     }          body {       background-color: black;       color: white;       text-align: center;       font-family: "Verdana", sans-serif;     }      <!DOCTYPE html>                 <meta charset="UTF-8">       <meta name="viewport" content="width=device-width, initial-scale=1.0">       <title>Netflix</title>       <link rel="stylesheet" href="style/style.css">

Wifi signal strength weak on Ubuntu 18.04 with rtl8723be

I have the Realtek rtl8723be driver on my HP-Pavillion Notebook.  While installing Ubuntu 18.04 LTS through plug-n-play option, I tried the following commands before actual installation:  sudo modprobe -r rtl8723be sudo modprobe rtl8723be ant_sel=2   and the wifi was working just fine.  But after installation alongside Windows 10, somehow the wifi stopped working properly, and now only wifi networks very close to the device appear.  I tried installing realtek software from  as mentioned in the README. But still no progress.   I even tried changing ant_sel parameters, then saving them to my /etc/modprobe.d/rtl8723be.conf and then performing a cold boot. But still no progress.  I also tried installing from , but I got errors.  sudo lshw -class network   *-network                         description: Wireless interface        product: RTL8723BE PCIe Wireless Network Adapter        vendor: Realtek Semiconductor Co., Ltd.        physical id: 0        bus info: pci@0000:08:00.0        logical name: wlo1        version: 00        serial: 70:77:81:bf:a7:b9        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless        configuration: broadcast=yes driver=rtl8723be driverversion=4.15.0-36-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11        resources: irq:18 ioport:5000(size=256) memory:c6100000-c6103fff   *-network        description: Ethernet interface        product: RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller        vendor: Realtek Semiconductor Co., Ltd.        physical id: 0        bus info: pci@0000:09:00.0        logical name: eno1        version: 0a        serial: 3c:a8:2a:ba:12:6f        size: 10Mbit/s        capacity: 100Mbit/s        width: 64 bits        clock: 33MHz        capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation        configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=rtl8107e-2_0.0.2 02/26/15 latency=0 link=no multicast=yes port=MII speed=10Mbit/s        resources: irq:19 ioport:4000(size=256) memory:c6004000-c6004fff memory:c6000000-c6003fff   *-network        description: Ethernet interface        physical id: 3        logical name: enp0s20u2        serial: ea:f8:17:e8:82:30        capabilities: ethernet physical        configuration: broadcast=yes driver=rndis_host driverversion=22-Aug-2005 firmware=RNDIS device ip=192.168.42.6 link=yes multicast=yes   Can anyone suggest what to do now?


How can I see a file's historical modification times?

In the view of the recent Worldbuilding election, I wanted to check the profile of the voters (based on Constituent badges awarded). And one idea was to look at the reputation of the users.  However some users have a rather low reputation on Worldbuilding (specifically) whereas they have a high reputation on other site. Is there a way to run a query on Worldbuilding, and see, for all users, their network reputation?

How to click only on the text of a header and not the empty whitespace to the right?

I am trying to make a link on a header be clickable on the text of the header only. Problem is, in my case, the link is still clickable, even when there is no text(it still clicks on empty blue space to the right). Example:  as you can see, the whole blue is clickable, but I just want the click to end after the "Hello World Link" word. Is there a way to allow to click only on the text "Hello World Link" and not the rest of blue empty space to the right? My code:

@title

   CSS:   .headerText{        h2:hover {          background-color: yellow;     }   }


Notify me that the edit queue is full before I suggest an edit

I have been editing an answer on , with some considerable amount of effort, and when I hit on Save Edits, the edit gets rejected with the following error. I got to know the meaning of this from .     The edit queue is full at the moment - try again in a few minutes!     I tried in a few mins, and still it didn't work. I believe that some edits might be valuable and this resists the users from doing so.   Main Question: Is there a way to show the queue limit at the beginning of the editing process? (So that we won't spend time on doing the edit, knowing it will fail)


Sampling distribution of exponential sample variance (formal not empirical)

Addressing this problem:  Let $X_1, ..., X_n$ be iid exp($\theta$) with pdf,  $f(x)=\frac{1}{\theta}e^{-\frac{x}{\theta}}$. What is the distribution of the sample variance?  This is to be done by proof, not by simulation/sampling. Everything online says simulation/sampling, so is there no formal mathematics for determining this distribution?

MySQL INSERT INTO SELECT vs BULK INSERTs performance

Currently, I am trying to copy data from TABLE1 to TABLE2. In terms of insertions performance, would it be the same or faster if I would to do  BULK INSERT manually (i.e BULK insert every 10K records into TABLE2 via INSERT INTO TABLE2 VALUES (1,2), (5,5), ...), versus INSERT INTO TABLE2 SELECT * FROM TABLE1


Windows explorer-like file manager for Linux with "List" view style

Is there any file manager for Linux with a view style similar to that of "List" in Windows Explorer? i.e: in the screenshot I have set it to "List" and sorted by type. In my couple decades of checking out Linux distros every now and then I've yet to see this feature in the file managers.


As an asylee, can I use my passport instead of my US re-entry permit?

I am an asylee in the United States. I have a Green Card, and my primary passport which was issued by my country of origin. I am not allowed to go back to my home city and then return to the United States.   But, due to an emergency, I have to go there. So, I decided to use a third country to go to from the US, stay there for a while, and then go to my home city then.   Can I use the re-entry permit that gets stamped while departing the US, have my passport stamped in the third country instead of the re-entry permit? I would enter my home country with the passport, and return to the US by the same route, only by showing my re-entry permit and not the passport as if I have never been to my home country?

Does the Sorting Hat use legilimency? Can an occlumens prevent it from working?

The Sorting Hat is able to look into a person's mind to learn about their talents, and can hear the thoughts of the person as well.     Hmm," said a small voice in his ear. "Difficult. Very difficult. Plenty of courage, I see. Not a bad mind either. There's talent, A my goodness, yes -- and a nice thirst to prove yourself, now that's interesting....   So where shall I put you?"      Harry gripped the edges of the stool and thought, Not Slytherin, not Slytherin.      "Not Slytherin, eh?" said the small voice. "Are you sure? You could be great, you know, it's all here in your head, and Slytherin will help you on the way to greatness, no doubt about that -- no? Well, if you're sure -- better be GRYFFINDOR!"      —Chapter 7: "The Sorting Hat", Harry Potter and the Sorcerer's Stone   Does the Sorting Hat get its mind-reading powers from the use of legilimency (the art of mind-reading)? Could someone skilled in occlumency (the art of closing one's mind against legilimency) be able to prevent the Sorting Hat from working?


I'm reinstalling my Kubuntu 12.04 and I want to take my Kate, Kile, Okular, Dolphin & Konsole config files with me.  Where are this files located? I've looked around /home/, /home/.kde/ and /home/.config/ but found nothing.


In the question  the OP was seeking a way to append multiple lines to a file within the shell. The solution:  cat <<EOT >> test.txt line 1 line 2 EOT   I want to prepend lines and my attempt looks like:  echo 3 >test.text cat test.text <<EOT >> test.text 1 2 EOT   But this results in an error:  cat: test.text: input file is output file   EDIT: for clarification, I am following a long server setup guide with instructions to manually edit configuration files. Editing at times involves prepending blocks of text to a file. In automating some of the steps, I want to retain the verbosity of the command by copying the text from the guide as-is and putting into a bash one-liner. For this reason the multi-line text input using EOT is preferred.    EDIT: other answers using sed require backslashes to be appended to the end of each line but I want to enter multiple lines without modification.  Is there a way to prepend multiple lines to a file in a similar fashion above (ideally without a temporary file and installing moreutils)?


Windows 10 upgrade from Home to Enterprise Version

I wonder, if it is possible to upgrade from Windows 10 Home to Windows 10 Enterprise like with Windows 8.1 where you can add features by entering a valid key for Pro. I'd test it, if I wouldn't have to reinstall everything in case it doesn't work...   I ask, because I need Remote Desktop for work, which Win10 Home hasn't.
