How to find original community description Before joining a community you can easily see the community description. For example, for example before joining the Programming Puzzles &amp; Code Golf Stack Exchange you see the description:     Programming Puzzles &amp; Code Golf Stack Exchange is a question and   answer site for programming puzzle enthusiasts and code golfers.   However, after joining I can no longer see this description. I can go to the on-topic page and see a different description:     Programming Puzzles &amp; Code Golf is for programming contests and   challenges. We welcome questions from beginners and experts alike.   Yet, I cannot seem to find the original description anywhere. Is there a way to find the original description while being logged into a Stack Exchange site?  Based on Rene's answer, I can click the Tour link on each site, but StackOverflow (and maybe other sites) do not have a tour link. Instead, I'd have to go there by manually typing it in the address bar. Is there a reason that this has been removed from the Stack Overflow page? Wasted screen space due to multiple horizontal bars at the top when an application is open in GNOME desktop Just moved from Unity to GNOME with the update to Ubuntu 17.10. There is a HUGE amount of wasted space at the top of the screen, when an application is open.  Evolution and Firefox both have four "bars" with 90% of each empty. Unity, to its credit was able to blend / mix these horizontal bars so there was only one / two.      Four is way too much. If this is GNOME I may carry on with Unity for the next six months.  Can anybody suggest a tweak/change/fix for this? Is there a definition of  and proper explanation of it?  It is said "Electric charge is the physical property of matter that causes it to experience a force when close to other electrically charged matter."  How is it though that matter can get charged?  Defining charge as the property of feeling a force with other charged matter seems circular.  What is charge?  Is there a non-circular definition / explanation? If I have two variables:  Object obj; String methodName = "getName";   Without knowing the class of obj, how can I call the method identified by methodName on it?  The method being called has no parameters, and a String return value. It's a getter for a Java bean. Should 'Hi', 'thanks', taglines, and salutations be removed from posts? says the following:     Saving an OS can be achieved by running sudo grub-set-default if   DEFAULT=saved is set in /etc/default/grub. It may also be saved if   GRUB_SAVEDEFAULT=true is also set in /etc/default/grub. In this case,   the default OS remains until a new OS is manually selected    from the   GRUB 2 menu or the grub-set-default command is executed.   I put the lines DEFAULT=saved AND GRUB_SAVEDEFAULT=true in /etc/default/grub, and ran sudo grub-set-default.  Here is the output:  $ sudo grub-set-default entry not specified. Usage: grub-set-default [OPTION] entry Set the default boot entry for GRUB.    -h, --help              print this message and exit   -v, --version           print the version information and exit   --boot-directory=DIR    expect GRUB images under the directory DIR/grub                           instead of the /boot/grub directory  ENTRY is a number or a menu item title.  Report bugs to &lt;bug-grub@gnu.org&gt;.   Am I not following the documentation correctly?  What's the correct way to do this? How do I add myself back as a sudo user? I clean-installed Ubuntu 11.10 today, and then installed VirtualBox.  This required me to add myself to the vboxusers group, and since 11.10 seems to no longer have a graphical app to add users to a group, I ran the following command:  sudo usermod -G vboxusers stephane   This is a problem.  I now see what I should have run instead is:  sudo usermod -aG vboxusers stephane   The end result is I'm no longer in the groups I should be in.  Including whatever group is required to run "sudo".  When I run any command as sudo now, I get the following:  $ sudo ls [sudo] password for stephane:  stephane is not in the sudoers file.  This incident will be reported.   Is there a way to fix this, or do I need to re-install from scratch again? Is it possible to search for punctuation/special characters? I tried to find a related question here, but was unsuccessful.  Someone on SO asked ... I tried searching SO and was presented with the search options page. Even Google fails at this search.  So my question is, is there some way to search for an exact word (in quotes) that won't cause it to fail? Workflow for converting LaTeX into Open Office / MS Word Format All beta sites (e.g. ) are appearing with 0 Q/D and 0 avid users.  is unaffected.  In the Q&amp;A spirit, my question is: Who borked the stats? "I have" vs "I have got" I don't know what is the difference between using "I have got" and "I have" For example:      He's got broad shoulders.    Is it possible to say:      He has broad shoulders.    If yes, so what is the difference? I am flying from Orange County, California to San Francisco, California and then on to Seoul, South Korea. If I check a bag will I have to pick it up in San Francisco and re-check it and go through security or customs for the international flight?  Everything I am reading leads me to believe that it's only necessary to re-check baggage and go through security and/or customs when you are first arriving into a country. However, since my first leg is staying within the United States I assume the airline will transfer my bag to the next flight and I can just go straight to the gate for my international flight?  Both legs of the flight are through the same airline (United Airlines) and there are only the two legs: OC -> SF, then SF -> Seoul. Can I travel to the UK on different dates from those on my entry clearance? I have a "Standard Visitor Entry Clearance" for the UK and will be traveling there from Saudi Arabia.    Is it necessary to travel on the same date I provided on my application?  Will the Immigration Officer check?  Will it make problems if I travel on a different date? Remove border from IFrame How would I remove the border from an iframe embedded in my web app? An example of the iframe is:  &lt;iframe src="myURL" width="300" height="300"&gt;Browser not compatible.&lt;/iframe&gt;   I would like the transition from the content on my page to the contents of the iframe to be seamless, assuming the background colors are consistent. The target browser is IE6 only and unfortunately solutions for others will not help. What follows if we fail to reject the null hypothesis? What conclusions can we draw if $p&gt;\alpha$? Does not rejecting the $H_0$ mean anything? Algorithm faster than Newton's for calculating $\sqrt{2}$ As we all know, going near a black hole (Gargantua in this case) slows down time, according to the theory of relativity.  So when Cooper comes out of the black hole, after spending a fair bit of time there, shouldn't he be much older than Brand who hasn't gone inside Gargantua? Restore open applications, documents, and window state When working on a project, I generally have a couple of Explorer windows open to relevant folders and a couple of applications (e.g. Eclipse and a form development tool) open to specific project-related documents.  There's a lot of value in that context, and I'd like to find a way to save a set of open apps under a project name, then restore that state at a later date.    Thus far all of the utilities I've found are virtual desktop products that don't save/restore state.  I'm specifically looking for something that will run the applications I had running, open the documents I had open, and position the windows as they were.  I'm amazed that such a seemingly simple concept as "Save my workspace state" doesn't seem to be available.  I'm on Windows 7.  Any suggestions? How can I request a random row (or as close to truly random as is possible) in pure SQL? I can't find .bash_profile in Ubuntu 14.04 in my /home/user directory. I used the ls -a command to see the .bash_profile, but there isn't such a file.
