SEO best practices for domains in multiple languages
How should I structure my URLs for both SEO and localization?
vim-clang-format: clang-format is not found I have an older iPod touch which which supports up to iOS 6.1.6 and nothing newer.  This device is equipped with a Linea Pro barcode scanner and previously had an application called "" installed.  Recently I was attempting to do some work on a web application I wrote and realized that I needed to update to a newer version of Web Barcode - but unfortunately the Apple ID saved on my device was deactivated a few years ago.  So I went to settings and updated it with my current Apple ID.  Then again tried to update the App from the Apple store.  Still no dice - it was asking me for the password on the old account.  So then I figured I'd just remove it and reinstall from scratch.  Deleted the app and went to the store but now I am met with a message that the new version requires at least iOS 8.0.  I feel I followed a very logical series of steps to update this application and while I can understand that I won't be able to install the newest version, how can I get the old version back?  The device is completely useless without the barcode scanning application and the Apple store is now refusing to install any version at all on my device.  What can I do to get the original version of this application reinstalled? Why do the Jedi say "May the Force be with you"? Echo from MySQL database with spaces and line breaks? I've added many PPAs using the add-apt-repository command. Is there a simple way to remove these PPAs? I've checked in /etc/apt/sources.list for the appropriate deb lines but they aren't there.   This is on a server system so a command line solution would be great! Validate that string contains only allowed characters in Ruby $N$-body simulation in General Relativity How would one perform an $N$-body simulation in General Relativity (GR) for something like galaxy formation or galactic dynamics?  Suppose one wants to simulate the rotation curve $v(r)$ for galaxies with an $N$-body simulation, and wants to do it in the framework of GR / the Einstein equations. When do merchants start paying the actual value of items without bonus effects and perks? A book suggests that we should not interchange "so" and "so that". "So" means "therefore", and "so that" means "in order that". However, it seems to me that in many cases they don't actually have a difference. For example:     Alice got up at 5:00 A.M., so that she could drive her son to school.   If I substitute "so that" with "so", this sentence presents the exact same causal relation to me:     Alice got up at 5:00 A.M., so she could drive her son to school.   I must have missed something here, since English is my second language. Could somebody explain the difference? Should I write "X and I", "X and me", "I and X", or "me and X" in a conjoined object? If $G$ is abelian, then the set of all $g \in G$ such that $g = g^{-1}$ is a subgroup of $G$ Prove that if $G$ is abelian then the set $H$ of all elements of $G$ that are their own inverses is a subgroup of $G$.   Naturally in an abelian group, $ab = ba$ for $a, b \in G$, however I'm not sure how to show the set elements that are their own inverses is a subgroup of $G$ using arbitrary elements. What are the Minecraft Easter eggs? I was looking at  and I didn't realize that Minecraft had some Easter eggs in it. Besides the Christmas chest Easter egg, and the sheep Easter egg, what else is there? How can Zeno's dichotomy paradox be disproved using mathematics? A brief description of the paradox taken from :     Suppose Sam wants to catch a stationary bus. Before he can get there, he must get halfway there. Before he can get halfway there, he must get a quarter of the way there. Before traveling a quarter, he must travel one-eighth; before an eighth, one-sixteenth; and so on.      This description requires one to complete an infinite number of tasks, which Zeno maintains is an impossibility. This sequence also presents a second problem in that it contains no first distance to run, for any possible (finite) first distance could be divided in half, and hence would not be first after all. Hence, the trip cannot even begin.      The paradoxical conclusion then would be that travel over any finite   distance can neither be completed nor begun, and so all motion must be   an illusion.   How can this be disproved using math, as obviously we can all move a walk from one place to another? How do I update Custom Label's value using apex? Which one would be a better option metadata api or tooling api? Please provide example ESM is available for 12.04, which enables Advantage customers to keep receiving kernel updates and updates for many user space packages. In our case it's very important to know if we'll be able tot use Ubuntu 14.04 safely after April '19, because it is not possible to upgrade our application and migrate it to say, 16.04. In ZFC set theory, every element object is a set. We know or feel that if $X$ and $Y$ are sets, their cartesian product $X\times Y$ is a set.  My question is: Why if $X$ and $Y$ are sets, their cartesian product $X\times Y$ is a set? Is the composition of two injective functions injective? Lost connection to MySQL server at 'reading initial communication packet', system error: 0 How to filter string for unwanted characters using regex? Title page line spacing I have a simple problem but I didn't manage to find any answer for it. In my title page, I just used  \title{Name of the title}   then  \hrule height 0,1cm \leavevmode \\[0,5cm]     {\Huge{\textbf{\@title}}}\\[0,5cm] \hrule height 0,1cm \leavevmode \\[0,5cm]   to print the title of my document. But it takes more than 3 lines on the PDF file, and I have a different spacing between the 1st and 2nd line compared to the 2nd and 3rd, which is a bit frustrating.   Anyone got an idea of why ?
