Does infinity exist in physical systems? Sometimes people fail at asking a question by being too broad, unclear like . So I'll take a stab at what I believe to be the same question, but more concise and clearly stated:     Does infinity exist in either terms of structure, parameters, or   measurement in any physical systems?   Can infinity have any real connection with reality?  Or is infinity purely a mathematical concept just used by physicists as a convenient way to describe the very large, an approximation?  I have heard that if you model a physical system (), and you run into infinity as a solution, then you have either made an error in your calculations or your model is wrong. When are you supposed to use escape instead of encodeURI / encodeURIComponent? When encoding a query string to be sent to a web server - when do you use escape() and when do you use encodeURI() or encodeURIComponent():  Use escape:  escape("% +&amp;=");   OR  use encodeURI() / encodeURIComponent()  encodeURI("http://www.google.com?var1=value1&amp;var2=value2");  encodeURIComponent("var1=value1&amp;var2=value2"); Where should looking-for-resources questions go? Questions like looking for css templates, blog templates, icons ... In general, resources (let's leave the licensing terms aside for now) which you might need when building a project of your own. Where should those questions go?  They're definitely not on-topic on Stack', SuperUser maybe although I doubt it. Webapps? Hmm, probably not.  Is there a place where they would be on-topic on the SE network? Checking if a key exists in a JavaScript object?

How to manage with edge to achieve that? Thanks Are there any good tools besides SeleniumRC that can fetch webpages including content post-painted by JavaScript? Prove that $6$ divides $n(n + 1)(n + 2)$ I am stuck on this problem, and was wondering if anyone could help me out with this. The question is as follows:  Let $n$ be an integer such that $n ≥ 1$. Prove that $6$ divides $n(n + 1)(n + 2)$. Note: An integer $a$ divides an integer $b$, written $a|b$, if there exists $q ∈ Z$ such that $b = qa$. Alternatively, $a|b$ if dividing $b$ by $a$, $b ÷ a$, results in an integer.  Should I do a proof by induction? All help/input is appreciated! I've only found a recursive algorithm of the extended Euclidean algorithm. I'd like to know how to use it by hand. Any idea? Let's say you have the ability to shine some light into a perfectly round sphere and the sphere's interior surface was perfectly smooth and reflective and there was no way for the light to escape.  If you could observe the inside of the sphere, what would you observe? A glow? And would temperature affect the outcome?  Seems silly, it's just something I've always thought about but never spent enough time (until now) to actually find an answer. How to generate PDF/A and PDF/X? I have heard about PDF  PDF/A (for archival) and PDF/X (for printing). How to generate LaTeX documents like that?  I'm also interested in answers with plain TeX and ConTeXt, and hopefully with both pdfTeX and XeTeX engines. I have a laptop with win7 installed. I have now made a 60gb partition which I want to install ubuntu into. The question I have, before I do the installation, is how large each of the root, swap, and home partition should be? I have read some place that root could be as small as 8GB, but isn't that too small? Since I guess beside ubuntu all the softwares installed will reside there as well? And I think I'm going to set my swap to be 2GB large.  My main concern is how large should the root partition should be. I'm mainly going to use ubuntu for programming and browse the web. Automatically change é to \'e – most convenient setup for accented letters? I assume this is really basic question, I'm new to LaTeX, I read a first step tutorial to get ready to write some documents but I couldn't answer my own question at this time and I really don't know where to search.  When I try to write é and compile my document, this character is not shown. I know the sequence is \'e to make it happen in the document but that is really disturbing to write.  Is there someway to write a paragraph "normally" and convert all the special chars into the LaTeX syntax? Or is there a way to allow é, à, ... writing so the compilation includes them into the document? I'm trying to find a good way to print leading 0, such as 01001 for a . While the number would be stored as 1001, what is a good way to do it? I thought of using either case statements or if to figure out how many digits the number is and then convert it to an char array with extra 0's for printing, but I can't help but think there may be a way to do this with the printf format syntax that is eluding me. text-overflow: ellipsis in table-cell without width Canonical question: One has a Windows 10 installed with display language A, but uses keyboard layout B. What does one need to do, to stop Windows from automatically adding an unwanted keyboard layout from language A to one's system?  My example: I have a Windows 10 in English and I'm using a Slovenian keyboard layout. And this is working just fine, until I run a certain program that Windows ever so intelligently thinks needs an US keyboard layout. Windows adds this unwanted layout automatically, switches to it and doesn't remove it afterwards. The new layout isn't even listed in installed layouts. The only way to remove it after it appears, is to manually add it as a keyboard layout and remove it.  It seems that's a common problem for many people but after many hours of googling, I just couldn't find a good solution for it... It would be perfectly fine with me if I could just completely remove the US keyboard layout from my system, but if I do that, the keyboard stops working in some programs altogether.  Programs that I or other people have this problem with: ICQ, some versions of Microsoft Office (lol), games based on Source engine, some versions of UltraVNC, Adobe CC Suite, and the list goes on. I'd like to emulate HTML's infinite page height using LaTeX/XeTeX, i.e. have the PDF pages grow higher until a manual \newpage is issued.  This could be emulated by setting a very large page height and using pdfcrop on the output (or just setting the page height manually), but I'd like a pure TeX variant and if possible support for footnotes etc at the bottom of the cropped page. Is the coefficient of friction always less than unity? What are the cases in which coefficient of friction is greater than unity? Does magic jack work on Ubuntu? Does magic jack work with Ubuntu? I originally had my magic jack on a computer with windows XP and I decided to switch to Ubuntu but I still want Magic jack. Animation Blending Basics Say I have a framework with characters that can run and walk and of course, stand still.  Am I right in thinking that animation blending is the process of smoothly transitioning between these by generating dynamic animations at runtime?  If so, what is the basic theory of how this works, and how would I implement it? Lots of questions in the reopen queue
