What's the best way to parse an XML dateTime in Java?
Is there a difference in meaning among 'should', 'happens to', or 'should happen to'? iPhone stuck on Connect to iTunes My iPhone is stuck on Connect to iTunes Screen (support.apple.com/iphone/restore iTunes logo and up arrow with lightning cable) I have Tried :-   Connecting it to iTunes and Updating, It updates Successfully.But on the same screen again   Restoring, It restores successfully.But on the same screen again  Tried Recovery Mode Screen Method and DFU method Tried Closing and Restarting iTunes Tried Deleting 'iPhone Software Update' folder in iTunes and Re-Downloding Updates    Nothing Works... Any Help will be appreciated How do I access folders created on Ubuntu with Windows? I have an external hard drive on which I back up my files, and I've moved some files from an Ubuntu laptop to it as well. However, I can't find a way to open the folder containing these files with my main Windows 10 laptop. When I try to open the folder "VPC 3 : UBUNTU" (the "VPC" is just a name for the laptop  with no special implications), the following happens:  It responds with "___ is unavailable. Make sure the disk is inserted..." In my family we have a DNA contradiction – two cousins (at about the 4th cousin level) took a Y-DNA test, but did not match and had two completely different haplogroups.   Since then, I have traced living cousins with the same surname – the only ones left living that I am aware of – and I would love to pay to have them tested to see if we can figure out where the non-paternity event (NPE) or other event happened (i.e. this new cousin could help us determine which line the NPE occurred in depending on which cousin he matches).   Does anyone have a sample letter, or know the best way to go about asking a distant cousin for DNA?   I have their address and am planning to write a letter, but I can't imagine receiving such a letter, so I am not quite sure how to ask without scaring them off. How do I update Android on my device? What is duplicate content and how can I avoid being penalized for it on my site? Can a finite sum of square roots be an integer? Can a sum of a finite number of square roots of integers be an integer? If yes can a sum of two square roots of integers be an integer?  The square roots need to be irrational. Why did Slytherin House not get disbanded? Doubly stochastic matrix proof A transition matrix $P$ is said to be doubly stochastic if the sum   over each column equals one, that is $\sum_i P_{ij}=1\space\forall i$.   If such a chain is irreducible and aperiodic and consists of $M+1$   states $0,1,\dots,M$ show that the limiting probabilities are given by   $$\pi_j=\frac{1}{1+M},j=0,1,\dots,M$$   I have no idea how to prove it but   If a chain is irreducible then all states communicate i.e $$P_{ij}&gt;0\space \text{and}\space P_{ji}&gt;0\space\forall i,j$$ If $d$ denotes the period of any state, if a chain is irreducible aperiodic, then $d(i)=1\forall i$   If $P_{(M+1)\times (M+1)}$ matrix and $\pi$ is the stationary distribution  $$\pi_j=\sum_iP_{ij}\pi_i\space j=0,1,\dots,M+1$$  but how I can get this expression? How to use early stopping properly for training deep neural network? I have a deep neural network model and I need to train it on my dataset which consists of about 100,000 examples, my validation data contains about 1000 examples. Because it takes time to train each example (around 0.5s for each example) and in order to avoid overfitting, I would like to apply early stopping to prevent unnecessary computation. But I am not sure how to properly train my neural network with early stopping, several things I do not quite understand now:   What would be a good validation frequency? Should I check my model on the validation data at the end of each epoch? (My batch size is 1) Is it the case that the first few epochs might yield worse result before it starts converging to better value? In that case, should we train our network for several epochs before checking for early stopping? How to handle the case when the validation loss might go up and down? In that case, early stopping might prevent my model from learning further, right?   Thank you in advance. Removing unwanted appearance of underlying mesh I've somehow lost my id_rsa.pub file. I still have my id_rsa file. How do I recover the public key from the private key?  (This question came up after ssh-copy-id was reporting "ERROR: No identities found" while ssh-keygen reported "/root/.ssh/id_rsa already exists". ls ~/.ssh pointed out the problem was having id_rsa but not id_rsa.pub. I found the solution, but it was buried at the bottom of a long post on an Ubuntu support forum.) Where can I find every gnome?

Fibonacci proof question: $f_{n+1}f_{n-1}-f_n^2=(-1)^n$ Somewhere on Stack Exchange I saw the equation     $$\gcd(2^m-1,2^n-1)=2^{\gcd(m,n)}-1.$$   I had never seen this before, so I started trying to prove it. Without success...  Can anyone explain me (so actually prove) why this equation is true?  And can we say the same when replacing the '$2$' by any integer number '$a$'?

Diagram of an artificial neural network Cartesian Product of Two Countable Sets is Countable How can I prove that the Cartesian product of two countable sets is also countable? Printing a file to a printer in Ruby Trying to get my head around the commutator subgroup. This is an excercise from Artin's Algebra:  Let $C$ be the commutator subgroup of $G$. Prove that $G/C$ is abelian.  Here is what I've done:  Let $xC,yC \in G/C$ then $xyx^{-1}y^{-1}C = C$ since $xyx^{-1}y^{-1}$ is a commutator hence belongs to $C$. But then $xyC = yxC$ so $xC$ and $yC$ commute in $G/C$. This can be done for any elements, so $G/C$ is abelian.  This seems somewhat surprisingly short. Is that all there is to it?   Regards
