Evaluating $\int \frac{1}{{x^4+1}} dx$ I have been trying to use Sidecar in the public betas of macOS Catalina and iPadOS 13.  I have a 2019 Macbook Pro, and a 3rd generation iPad Pro, so I know I have supported devices.  Both devices are on the same Wifi network, and both have Bluetooth enabled.  Both devices are logged into iCloud with the same AppleID.  Both devices have two-factor authentication enabled.  I have tried this both with and without a USB-C cable connection between the two devices.  The Sidecar preference pane in System Preferences does appear, and when I go into it I can see in the "Select Device" dropdown that my Mac can "see" my iPad Pro.  However, when I try to connect to it, I get the following after a pause:    I keep  for troubleshooting tips, but none have been useful for me thus far.  FWIW, I have been a "good citizen" and reported my problems to Apple via the Feedback Assistant apps on both devices, so in case this is a temporary bug, I've reported it.  I'm just asking here in case someone else has encountered this issue.  Edit: Eventually, Sidecar started working for me (sometimes) after some of the later public betas came out.  I'm not sure exactly which version(s) of Catalina and/or iPadOS made the difference for me.  So far it has worked without any timeouts in the final versions. I didn't need to downgrade and then re-upgrade as the submitted answer suggests, although I'm glad that has worked for some. I came across this strange code snippet which compiles fine:  class Car {     public:     int speed; };  int main() {     int Car::*pSpeed = &amp;Car::speed;     return 0; }   Why does C++ have this pointer to a non-static data member of a class? What is the use of this strange pointer in real code? I am stuck with the following problem.     Prove that $$\limsup_{n \to \infty} (a_n+b_n) \le \limsup_{n \to \infty} a_n + \limsup_{n \to \infty} b_n$$   I was thinking of using the triangle inequality saying $$|a_n + b_n| \le |a_n| + |b_n|$$ but the problem is not about absolute values of the sequence.  Intuitively it's clear that this is true because $a_n$ and $b_n$ can "reduce each others magnitude" if they have opposite signs, but I cannot express that algebraically...  Can someone help me out ? I know the definition of Airplane mode is all communications and radio signals are blocked. But is it possible to turn off the "calling/receiving" part of the phone so your phone is not connecting to a cell tower and only allow Wifi? I've looked into a couple of apps in Google Play but they're either not working or out of date with newer versions of Android.   I know there is strong opinions on both sides of the issue but I'm worried about radiation from my phone since i use it a lot in bed and I hold the phone close to my head and face. At night I'm not worried about receiving calls, so I just want to turn off the phone part and  use WiFi. Is there a way? Or am i just crazy and paranoid? I upgraded my Mega Ring and have been looking for Mega Stones, and I found . However, the Mega Stone isn't in the place it's supposed to be, and I'm sure the location is right. Why isn't my Mega Stone here? When is the expected stable release date of Ubuntu Phone and Ubuntu Tablet? Is there an expected stable release date of Ubuntu Phone and Ubuntu Tablet?  If so, what are their dates? Custom Edit control inside a ExtJS Editor grid How to get contact from stolen Android phone? I already read . And that answer did not work for me. I have explained it on the question.  My android phone was stolen. I need to get all contact of my phone. I had enable sync in that phone.  When I visit , it has only a very few contacts (seems like below 10% and all them has an email too). How can I get all contacts?

Paper status changed to “Decision in Process” rapidly after initial submission How do I load the contents of a text file into a javascript variable? I have a text file in the root of my web app  and I'd like to load it into a variable in javascript.. in groovy I would do this:  def fileContents = 'http://localhost/foo.txt'.toURL().text; println fileContents;   How can I get a similar result in javascript? The square roots of different primes are linearly independent over the field of rationals How do I fix my locale issue? Find the probability of an event determined by an inequality on exponential random variables Let X and Y be independent random variables such that $X∼Exp(1)$ and $Y∼Exp(2)$.  Find the probability that $3X+4Y≤5$.  I thought the equation for solving this was the integral from $\int_0^a \int_ 0^{(a-y)} \lambda_1 e^{-\lambda_1 x}\lambda_2 e^{-\lambda_2 y} dx dy$ where $a = 5$, so I first started with the integral from $\int_0^5 \int_0^{(5-y)} 3 \times 1e^{-1x} \times 4 \times 2e^{-2y} dx dy$ and got $23.83828927$ which is much larger than a probability can be. Any help? Why are passports checked at the check-in counter, Immigration and even at the gate? I was wondering, why there are passport checks at the check-in counter, Immigration and even at the gate?    For example, I was at Istanbul flying to either UK or US. There's a security check at the check-in counter asking a bunch of questions about my immigration status - even more than the Immigration officer at the border. Also, at the gate, there's also Security officer checking my immigration status and passport asking the same questions.    I thought that would be the responsibility of an Immigration officer rather than some third party company?   The thing I'm curious the most is they don't even know which countries this passport can go to with or without visa. They have to go back to the counter and check with the system which takes a long time. I was wondering why they hire these kind of companies to slow down the process? How to make equally sized windows in corners of the screen? I have Ubuntu 18.04 LTS installed. I inserted USB-flash to my laptop. It was automounted to /media/username/DISKLABEL and opened in Nautilus. I can read and write objects to it. How can I access it from the application, which is installed as Snap?
