Why do we tag questions? My question—my meta-question as the case may be—concerns the purpose of these words referred to as "tags". Let me be clear: I use tags. The site supports them, so why shouldn't I? My understanding of their reason for existing is tragically incomplete.   Are they used for searching? Are they useful in any other way, or do they merely act as decoration?     For more information, see "" and "" in the . Can a US citizen leave and enter the US using a foreign passport? I am a dual citizen. I have both a US passport and a non-US passport. I live in the US. My US passport is currently being processed for renewal. I am unsure whether I will receive my passport in time for a trip that I have scheduled. Could I use my non-US passport to leave the US and return? I have never entered the US with my non-US passport. There is no immigration leaving the US but I still need to scan my passport for ticketing. Will the airline refuse me a ticket? I know that in this situation returning with a non-US passport can be problematic as well, but will I be able to leave at all? Note that I am traveling to a country which neither of my passports are from. How to best determine if a bike will fit without riding it Why would using higher ISO and faster shutter speed yield more noise than using lower ISO and slower shutter speed? I recently tried to change a bulb using an adaptor (converting from a E27 to B22 fitting). After switching on the light fitting the fuse had blown. After inspection it turns out the adapter is faulty and must have caused a short-circuit.  After removing the bulb and resetting the switch in the main fuse box, I am now unable to operate the switch on the wall to turn the fitting off (the switch physically won't click).   Is there something I can do to fix the problem?  Thanks, After Windows 10 Fall Creators Update, a svchost.exe instance is constantly using CPU time Since installing the Windows 10 Fall Creators Update, I have a svchost.exe process that is constantly using about 14​ % of CPU time:    This svchost.exe instance is responsible for hosting three services:    The CPU time is consumed by a thread inside that process that  cannot attribute to any of these three services:    Given that these three services are considered critical system services, it's hard to do anything about them. These services cannot be stopped or disabled by services.msc, and terminating the process triggers a bugcheck (CRITICAL_PROCESS_DIED). Disabling the Windows Defender Firewall through the settings UI does not reduce CPU usage.  I'm out of ideas. What could be causing this? How can I debug this further? Is there a workaround to stop these services?    Update: After some debugging with , we've isolated this to the Windows Defender Firewall service. Process Monitor shows that it's constantly accessing the registry:    A CSV export of a Process Monitor capture, filtered to that process, is available .  I’m still looking for a way to stop that behavior.    Update 2: Analysis with the Windows Performance Analyzer shows that most CPU time is consumed by code from rpcrt4.dll: Continuous and bounded imply uniform continuity? As per c99 standard, size of long long should be minimum 64 bits. How is this implemented in a 32 bit machine (eg. addition or multiplication of 2 long longs). Also, What is the equivalent of long long in C++. How to insert the content of a file into another file before a pattern (marker)? File1 contents:  line1-file1      "1"  line2-file1      "2" line3-file1      "3"  line4-file1      "4"    File2 contents:  line1-file2     "25"   line2-file2     "24"   Pointer-file2   "23"   line4-file2     "22"  line5-file2     "21"   After the execution of perl/shell script, File2 content should become:  line1-file2     "25"   line2-file2     "24"  line1-file1      "1"  line2-file1      "2" line3-file1      "3"  line4-file1      "4"  Pointer-file2   "23"  line4-file2     "22"  line5-file2     "21"   i.e  paste the contents of File1 in File2 before the line that contains "Pointer". Connectedness in the Quotient Space The problem says this:  Let $\sim$ be an equivalence relation in $X$ and consider the quotient space $X/\sim$. Prove that:   $X$ connected $\Rightarrow$ $X/\sim$ connected. If $X/\sim$ is connected and every equivalence class $[x] = \left \{ y\in X : y \sim x \right \}$ is connected then $X$ is connected.   Proof 1) is easy and I know how to do it. But I'm stuck in the proof 2). That's what I have tried:  Let's suppose $X$ isn't connected. Then, $X=U\sqcup V$ with $U$ and $V$ open.   Let $\pi : X\rightarrow X/\sim$ be the application that sends every $x\in X$ into his class. I want to see that $\pi (U)$ and $\pi(V)$ are open and that $\pi (U)\cap\pi (V)= \varnothing$ to conclude that $X/\sim$ isn't connected (because $\pi$ is surjective). But that is absurd, so $X$ must be connected.  I know how to prove that $\pi (U)\cap\pi (V)= \varnothing$, but I don't know how to show that $\pi (U)$ and $\pi(V)$ are open. Any advice?  Thanks! Prove or the disprove the existence of a limit of integrals Let $A \subset \mathbb{R}^2$ be the annulus defined, in polar coordinates, as  $$ A = \{ (r, \theta) \in [0, \infty) \times [0, 2\pi) : 2 \leq r \leq 3 \} \, .$$ Let $F: A \to A$, $F:(r, \theta) \mapsto (r, r \theta \text{ (mod } 2\pi))$. Let $g : A \to \mathbb{R}$ be a continuous function. Discuss the existence of the limit $$ \lim_{n \to \infty} \int_A g \circ F^{(n)}(x) \, \text{d}x \, ,$$ where $F^{(n)} = F \circ F \circ \dots \circ F$ denotes the composition of $F$ with itself $n$ times.  I cannot find a way to attack this problem. Here's what I tried: if $g \circ F^{(n)}$ converged, I think we could take the limit under the integral sign. So I tried to show the convergence of $F^{(n)}$. If it converged, then the limit function must send every point to a fixed point of $F$. So I determined the fixed points of $F$. But I don't think $F^{(n)}$ converges. Has it been practically proven that quantum superposition exists ? If yes, how does it even work? Are these solutions of $2 = x^{x^{x^{\:\cdot^{\:\cdot^{\:\cdot}}}}}$ correct? Search for ,        ,                        and you will see that "results found containing __" is just a little too close to the header. It's not like there isn't  to have it be a little lower, closer to "Search":          The UI has been updated since I took the above screenshots, and the text you search for is  (which fixes another design issue but not the one in this question): Conditional Formatting: 3 color scale showing text relevance in Excel for Mac Is there a way to use conditional formatting in the following manner in Excel? (For those who are curious, I am using Excel 2010 for Mac)  I want Cell B2 to be green when A2 says "John likes green apples" and B2 also says "John likes green apples", yellow if A2 says "John likes green apples" and B2 says "Bill likes blue apples", and red if A2 says "John likes green apples" and B2 says "Bill hates red oranges".  I am just wondering if there is a way to something to that effect.  Thanks Why did Bilbo physically age faster than Gollum? Opening a context menu (with the Menu key) Auto generate an Index Is there any way to auto-gererate an index for the makeidx package? I've written ~270 pages and didn't think of adding \index{} everywhere.  Do I really need to go over everything and add \index{}? I'm running 12.04 - I installed kubuntu to try it out and realized that with all the bloatware applications that I didn't want it anymore - I was able to uninstall the kubuntu-desktop but there are still packages left over... How can I make sure I get rid of EVERYTHING Kubuntu installed - even the kde leftovers?  Here's some of what's left when I ran sudo apt-get autoremove kde then "tab" it displayed this:     kdeaccessibility              kdepim-runtime kdeadmin   kde-runtime kde-baseapps                  kde-runtime-data   kde-baseapps-bin              kdesdk-dolphin-plugins kde-baseapps-data   kde-style-oxygen kde-config-cron               kdesudo kde-config-gtk    kdeutils kde-config-touchpad           kde-wallpapers   kdegames-card-data            kde-wallpapers-default   kdegames-card-data-extra      kde-window-manager kde-icons-mono   kde-window-manager-common kdelibs5-data                 kde-workspace   kdelibs5-plugins              kde-workspace-bin kdelibs-bin   kde-workspace-data kdemultimedia-kio-plugins   kde-workspace-data-extras kdenetwork   kde-workspace-kgreet-plugins kdenetwork-filesharing   kde-zeroconf kdepasswd                     kdf kdepim-kresources   kdm kdepimlibs-kio-plugins        kdoctools   Those are all installed by kubuntu... correct?  I just want to go back to my Ubuntu 12.04LTS with Gnome2-classic and without all the kubuntu extras.  I started it off by just removing unnecessary apps that came with kubuntu-full - then realized I didnt want the whole thing at all and uninstalled kubuntu-full but it still says I have these as well:     alex@griever:~$ sudo apt-get --purge remove kubuntu-   kubuntu-debug-installer           kubuntu-netbook-default-settings   kubuntu-default-settings          kubuntu-notification-helper   kubuntu-firefox-installer         kubuntu-web-shortcuts How to set HttpResponse timeout for Android in Java I have created the following function for checking the connection status:  private void checkConnectionStatus() {     HttpClient httpClient = new DefaultHttpClient();      try {       String url = "http://xxx.xxx.xxx.xxx:8000/GaitLink/"                    + strSessionString + "/ConnectionStatus";       Log.d("phobos", "performing get " + url);       HttpGet method = new HttpGet(new URI(url));       HttpResponse response = httpClient.execute(method);        if (response != null) {         String result = getResponse(response.getEntity());         ...   When I shut down the server for testing the execution waits a long time at line  HttpResponse response = httpClient.execute(method);   Does anyone know how to set the timeout in order to avoid waiting too long?  Thanks!
