Why does the shadow-root styles put display none on my .fa-xxx classes?  The shadow-root thing adds the classes I use to a display none pile, but only the specific ones I add!  I'm using PHP to include navigation, footers and such, but these don't get effected by it. For example it works just fine in my navigation. There it displays the font just fine.  What is causing this, and how do I control it?
(clickable)  Mainad has a valid height and width, however it isn't shown like subad1/subad2. Which are in essence exactly the same! (just a different background image).  Firebug shows my div as greyed out for some weird reason. Replacing the contents of mainad with just some text doesn't solve the problem (problem isn't related to inner elements)..   What's going on?! :(
Show current ping to website on Taksbar I'm looking for a way to monitor my current internet connection quality by showing the ping-response to a website like google in the taskbar on the right side. I'm using Windows 8.1. Kind of like , but for the ping. Any suggestions?  I want to stop using the command line to ping Google. Part of a fingernail known as the  is informally known as the "quick".  It is referenced in the saying "cut to the quick".  What is the etymology of the word quick as in reference to the fingernail? How to get the full executable name of a running process in Linux Some fields like Economics and Maths have their work in progress published as "working papers" with notes like "work in progress, do not cite or quote without the author's permission."Sometimes they upload these to their own websites or to their universities websites. I don't see much of this going on in my own field (sociology). I have heard from people that are afraid of having their work scooped or that fear that work published in this way will not be considered as "unpublished" by journals and conferences.  What are the advantages of making work in progress available in this way? Recently I installed Ubuntu 16.04 on my HP Envy 17t and everything works fine. However, I need to disable the touchscreen input permanently and I tried everything I could found but nothing works.  The closest thing I could manage was to make a shell script that will run at startup (the shell script calls xinput set-prop "Touchscreen Input Name" "Device Enabled" 0 command).   However, this script will not run until I log in. My touchscreen needs to be disabled at the log-in screen.  How can I solve this? I tried modifying the 10-evdev.conf file but all I got is a purple screen and a broken Ubuntu setup. How do I check if an array includes a value in JavaScript? Is there a way to get the red artifact in Undertale? My brother has been trying different ways of getting the artifact without the Annoying Dog consuming it, but has been unsuccessful. I'm kind of curious as well. The artifact is obviously a throwing ball, but I kind of want to know the description for the artifact itself, and if you need to cheat to get it... If it even is an item in the code, too. I'm using  to go through JavaScript, and it's returning many suggestions to replace == (two equals signs) with === (three equals signs) when doing things like comparing idSele_UNVEHtype.value.length == 0 inside of an if statement.  Is there a performance benefit to replacing == with ===?   Any performance improvement would be welcomed as many comparison operators exist.  If no type conversion takes place, would there be a performance gain over ==? How to get straight quotation marks? How do I get straight quotation marks, i.e., " and ' in TeX?  (No, \verb changes the font and this is unacceptable.)  [Edit]  I forgot to mention that I’m using XeLaTeX, and fontspec is a necessity.  The first two proposed answers did work, without fontspec. Are S.P.E.C.I.A.L. skills capped at 10? We know that the maximum level a dweller can train to on any SPECIAL skill is 10, however this does not consider bonuses given from their outfit.    Is there any additional benefit for going over 10? For example, a dweller with an Intelligence skill of 10 wearing a lab coat that boosts Intelligence by 3?   If it is a hard cap, would it be more useful to use outfits that raise a secondary characteristic instead? how can I add an overlapped anchor in both overlapped paths automatically Hello Physics StackExchange!  I will put the TL;DR in the beginning: I need a self contained, relatively hand-holding sequence of textbooks that covers up from the end of Griffith's Intro to QM to relativistic QM/particle physics to QFT.    This will be my first post. I'm a medical physics grad student who majored in biomedical engineering for my undergrad, with serious regrets about not doing math/physics double major in hindsight. Oh well. I've made it my goal to eventually understand QFT.  My background in relevant subjects is Calc 1 to 3 and Diff EQ, 2 part freshman physics, an E&amp;M course that used Griffiths Electrodynamics, a summer of self studying Griffith's QM (got most of the way through). I will also be officially taking a class in QM using Griffith's textbook this next spring. I am aware of the Lagrangian and Hamiltonian approaches to mechanics as well. In addition I have familiarity with special and basic general relativity using tensors and all this. What would be the best way for me to get from where I am now to a strong understanding of QFT autodidactically? I have no aversion to studying pure maths where I need to.  EDIT: My question is much different than simply asking for a handholding explanation of QFT. Generally these textbooks assume a certain amount of physics/math background, and I was asking for a sequence of textbooks leading up to QFT from the end of a specific textbook, Griffith's QM. Did you even read my question? Did you read the thing you linked me to? I am not talking about mirrors, just a plain window made of glass like material. Would it be possible to allow light pass only in one direction but not the other? Bmp to jpg/png in C# This is a question in Ahlfors in the section on the argument principle: How many roots of the equation $f(z)=z^4+8z^3+3z^2+8z+3=0$ lie in the right half plane?  He gives a hint that we should "sketch the image of the imaginary axis and apply the argument principle to a large half disk."  Since $f$ is an entire function, I think I understand that the argument principle tells us that for any closed curve $\gamma$ in $\mathbb{C}$, the winding number of $f(\gamma)$ around 0 is equal to the number of zeros of $f$ contained inside $\gamma$.  How would you go about actually applying the hint though? I am having trouble figuring out what the image of a large half disk under $f$ would look like. We can solve the equation $x^x=c$ using the Lambert $W$ function, but how do we solve $x^{x^x}=c$ , How to know current name of the database in Django? Underfull \hbox in bibliography I am getting lots of "Underfull \hbox" warnings that point to the *.bbl file. It looks like these messages appear only when URLs are very long, like in the below example:  @techreport{nistguidesec,   author    = {Wayne Jansen and Timothy Grance},   title     = {Guidelines on Security and Privacy in Public Cloud Computing},   month    = {January},   note     = {Draft Special Publication 800-144. Available at \url{http://csrc.nist.gov/publications/drafts/800-144/Draft-SP-800-144_cloud-computing.pdf}}, }   In the produced PDF text is correctly hyphened and links are correctly split over several lines (I am using hyperref package)  How can I avoid annoying warning messages about "underfull \hbox" pointing to bibliography? tarring in parallel An Oceanographer friend at work needs to back up many months worth of data.  She is overwhelmed so I volunteered to do it.  There are hundreds of directories to be backed up and we want to tar/bzip them into files with the same name as the directory.  I can do this easy enough serially - but - I wanted to take advantage of the several hundred cores on my work station.  Question:  using find with the -n -P args or GNU Parallel, how do I tar/bzip the directories, using as many cores as possible while naming the end product:  origonalDirName.tar.bz2?  I have used find to bunzip 100 files simultaneously and it was VERY fast - so this is the way to approach the problem though I do not know how to get each filename to be that of each directory. A current I flows through a solenoid (with n turns). Self inductance is $L$. If the magnetic flux is $\phi$, I am taught that $-n\phi=LI$  I dont understand the part with $n$, why do we have multiply by $n$? $\phi$ itself represents the whole magnetic flux there, if $\phi$ implied the flux only occurred by one coil, then it would be correct.   Moreover, flux change by a coil ($n$ turns) in $dt$ time is $d\phi$, so the induced electromagnetic force is   $$dE=n \cdot \frac{d\phi}{dt}$$   Why do we multiply by $n$ here? If $\phi$ means the whole flux, then why multiply?
