Around one month ago I changed the name of one paper of mine on ArXiv. I noticed that on google scholar it still appear with the old name and that if I search on google with the new name it does not find anything.  Is there a workaround to fix this problem?
I know that new arXiv papers usually appear in Google Scholar within a few days or weeks. My question is: if someone submits a replacement of his/her arXiv paper, does the new version of the paper also appear in Google Scholar?
Why does every server I try say it can't connect? I just re-purchased Minecraft (because my old profile stopped working so I bought it) after not playing it for a couple of months. I've added a bunch of servers, but almost every one says "can not connect."  I know its not because the server is not 1.7.2, because I checked that they'd update. It will say "server can't connect" after a long time. I don't know if its me or the servers.  My server screen looks like this (notice the one at the bottom – it's still loading!): Is it possible to add new predictions/autofill in Overleaf? For example, when I use the command (in Overleaf/ShareLaTex):  \begin{figure}[H]     \centering     \includegraphics{some_graphic}     \caption{some_caption}     \label{fig:some_label} \end{figure}   the \includegraphics{} comes without the [] parameter to change the size of the image, and \begin{figure} without the [H] option by default.   Is it possible to renew the command to make it default? By that I mean that when I type the \begin{figure} command it adds the [H] and [h] as well as [width=\textwidth] in the \includegraphics command, rather than making a global change in the preamble e.g. What is the fastest way to create a list of directories specified in a file? I have a text file, "foo.txt", that specifies a directory in each line:  data/bar/foo data/bar/foo/chum data/bar/chum/foo ...   There could be millions of directories and subdirectories What is the quickest way to create all the directories in bulk, using a terminal command ?  By quickest, I mean quickest to create all the directories. Since there are millions of directories there are many write operations.   I am using ubuntu 12.04.  EDIT: Keep in mind, the list may not fit in memory, since there are MILLIONS of lines, each representing a directory.  EDIT: My file has 4.5 million lines, each representing a directory, composed of alphanumeric characters, the path separator "/" , and possibly "../"  When I ran xargs -d '\n' mkdir -p &lt; foo.txt after a while it kept printing errors until i did ctrl + c:  mkdir: cannot create directory `../myData/data/a/m/e/d': No space left on device  But running df -h gives the following output:  Filesystem      Size  Used Avail Use% Mounted on /dev/xvda        48G   20G   28G  42% / devtmpfs        2.0G  4.0K  2.0G   1% /dev none            401M  164K  401M   1% /run none            5.0M     0  5.0M   0% /run/lock none            2.0G     0  2.0G   0% /run/shm   free -m   total       used       free     shared    buffers     cached Mem:          4002       3743        258          0       2870         13 -/+ buffers/cache:        859       3143 Swap:          255         26        229   EDIT: df -i  Filesystem      Inodes   IUsed  IFree IUse% Mounted on /dev/xvda      2872640 1878464 994176   66% / devtmpfs        512053    1388 510665    1% /dev none            512347     775 511572    1% /run none            512347       1 512346    1% /run/lock none            512347       1 512346    1% /run/shm   df -T  Filesystem     Type     1K-blocks     Used Available Use% Mounted on /dev/xvda      ext4      49315312 11447636  37350680  24% / devtmpfs       devtmpfs   2048212        4   2048208   1% /dev none           tmpfs       409880      164    409716   1% /run none           tmpfs         5120        0      5120   0% /run/lock none           tmpfs      2049388        0   2049388   0% /run/shm   EDIT: I increased the number of inodes, and reduced the depth of my directories, and it seemed to work. It took 2m16seconds this time round. How are character special files and block special files different from regular files in a Unix-like system? Why are they called “character special” and “block special” respectively? Real life uses of Moment generating functions In most basic probability theory courses your told moment generating functions (m.g.f) are useful for calculating the moments of a random variable. In particular the expectation and variance. Now in most courses the examples they provide for expectation and variance can be solved analytically using the definitions.   Are there any real life examples of distributions where finding the expectation and variance is hard to do analytically and so the use of m.g.f's was needed? I'm asking because I feel like I don't get to see exactly why they are important in the basic courses. The day before yesterday I think, my daughter asked me where we were going and since I was not planning to do the weekly shopping on that day and I just wanted to buy some stuff from two stores, I said offhand we are going to the shops! Looking back, it seems when I don't find a NAmE word I turn to UK if I know of.  So what do you say when:   go shopping (it's just go shopping!) you go to buy something specific; I mean you're not going shopping, and it's usually found in any store. You don't have to shop around. you want to buy non grocery or clothing stuff, maybe a can of paint and a spare part for your car together.    I have found some kind of answer for this question on , but I prefer to get a clear answer to my points above, and also if you agree with this native speaker about using store in singular form not plural:     Just as a side note, we don't use the plural in American English. "I'm   going to the store" (even if I may visit several stores), not "I'm   going to the stores". (If we know we are going to several stores I   think it would be more likely to say "I'm going shopping" or even "I'm   going downtown" in smaller towns.) What's the best way to animate an illustration for the web? I have a couple of illustrations done in Illustrator and I am planing to animate it for a website that I am working on, I've heard of  toolkit with flash, but is it the best way to go or is there another "better" way of doing it?  Here's an example of the kind of animations I am aiming for: How to delete a keyboard layout in Windows 10 I installed Windows 10 on a physically German keyboard, then installed a Window English software keyboard and bought some little stickers to make my keyboard look OK.  However, Windows shows 2 keyboards installed &amp; occasionally toggles back to German.  Note that I am not talking about removing a language (which is all that I can find when I Google).  How do I remove the German keyboard layout? In naive set theory, I believe ∅ = {∅} = {{∅}} is correct, but just wanted to make sure that I understood this correctly.   ∅ is an empty set, so having an empty set as an element of a set that contains nothing else is pretty much the same thing as e.g. marking the number 2 as 2.000000, right? Doesn't the symbol ∅ intrinsically imply that this is an empty set which contains it self? The statement is: $f$ is a real fucntion on $\mathbb R$. Then if $f'(x)=f(x)$ and $f(0)=1$, then $f(x)\neq 0.$ Differences between longtable and xtab I have a pretty simple table that needs to span multiple pages. This seems like a job for either the / package or the  package.   The voting on the answers to this  suggest that longtable is the preferred package, yet xtab is much newer and has been revised since that question was asked.  What are the differences between xtab and longtable and when is one preferable to the other? I know that the derivative of the inverse function of $f(x)$ is $g'(y) = \frac{1}{f'(x)}$ But how to derive the formula for the second derivative of g(y) knowing that $\left[\frac{1}{f(x)}\right]' = -\frac{f'(x)}{(f(x))^2}$ ?  I just started studying this chapter, so please try to be as simple as possible ;-) Thank you. I'm starting  and finally decided to learn how to write epsilon-delta proofs.  I have been working on chapter 5, number 3(ii). The problem, in essence, asks to prove that     $$\lim\limits_{x \to 1} \frac{1}{x} = 1.$$    Here's how I started my proof,     $$\left| f(x)-l \right|=\left| \frac{1}{x} - 1 \right| =\left| \frac{1}{x} \right| \left| x - 1\right| &lt; \epsilon \implies \left| x-1 \right| &lt; \epsilon |x|$$   I haven't made any further progress past this point. Is it possible to salvage this proof? Should I try an alternate approach? I've been having trouble defeating this monster. Even with lots of buff potions, health potions, high tier armor (Molten), and ranged weapons with plenty of ammo (Minishark), I can't seem to kill this boss.  Worse, when I get it down to about 2000 hp, even if I'm fairly far away, it'll suck me in and continually rise towards the skybox, which doesn't allow me to do anything for some reason.  How do I defeat the Wall of Flesh? What gear should I be using and what kind of potions do I need? Find the Galois group of $x^3-5$ over $\mathbb{Q}$. In this case, the roots of $x^3-5$ are $\{\sqrt[3]{5},\omega\sqrt[3]{5},\omega^2\sqrt[3]{5}\}.$ I think $\mathbb{Q}(\sqrt[3]{5},\omega\sqrt[3]{5})$ is the splitting field of $x^3-5.$ Then, $[\mathbb{Q}(\sqrt[3]{5},\omega\sqrt[3]{5}):\mathbb{Q}]=3,$ I think the automorphisms are: $$id$$ $$\sigma:\sigma(\sqrt[3]{5})=-\sqrt[3]{5}$$ $$\tau:\tau(\omega\sqrt[3]{5})=-\omega\sqrt[3]{5}$$ I'm not sure about what I have done. But how to determine the Galois group based on this? And how to determine the solvability of this polynomial? Why does connecting a high-current device to my digital circuit cause weird behavior? Internet through wireless hotspot, intranet through wired network - can I use both at the same time? Hereditary properties with nested frames (mdframed and tikz) How to prove that $z\gcd(a,b)=\gcd(za,zb)$ I need to prove that $z\gcd(a,b)=\gcd(za,zb)$.    I tried a lot, for example, looking at set of common divisors of the two sides, but I can't conclude anything from that. Can you please give me some advice how I can handle this problem? And $a,b,z \in \mathbb{Z}$. Does a correlation matrix of two variables always have the same eigenvectors? I perform Principal Component Analysis using two variables that are standardized. This is done by applying a SVD on the correlation matrix of the concerned variates. However, the SVD gives me the same eigenvector (weights) irrespective of what the two variables are. It's always [.70710678, .70710678]. I find this strange. Of course, the eigenvalues differ.  My question is: How to interpret this?    PS. I wanted to conduct a total least squares regression on two variables. My statistical programme does not provide TLS, but TLS luckily equals Principal Component Analysis, as far as I know. Hence my question. The question is not about TLS directly, but why I get the same eigenvectors irrespective of which variables I use (as long as they are exactly 2).
