In "Ask Question" page of SE sites displays list of question already asked based on the title of the current question, it would be helpful if the questions are ordered based on the tags if tags are added in the current question being asked.  For example:  In Stackoverflow if the question is "Call super class method" and the tag is , first two questions are in  and . If those questions are in c# it will be helpful and reduce duplicate questions.
When asking a new question and typing in the title we get a list of similar questions named     Questions that may already have your answer     That suggestions contains posts across all tags. Like the example in the screenshot it returns similar questions for Python, jQuery, SQL, C#, Java, C++, ...  This makes the list less useless unlikely people find a question that already answers theirs. If people actually find a similar question in that list many duplicates could be avoided.  So can tags I entered below the question be considered to update the list? And can the tag textbox maybe put above the question title?
Centos recently updated to 7.3 and there's been problems with sshd sftp group permissions. I have one user that is chrooted to it's home directory, and that user is in group sftponly. Then i have the /var/www directory, which has 775 permissions and owner is apache and owner group is sftponly. I have a bind link pointing from /home/user/files/web --> /var/www, so the user can access /var/www even though being chrooted to it's home directory. I can view files in /var/www with that user, but impossible to edit or add anything. This worked fine before the big Centos 7.3 update, and now it's stopped working. Any ideas? Linux: coloring bash prompt will break carriage return When I try to colorize the bash prompt like this:  export PS1="\e[0;31m[\u@\h \W]\$ \e[m "   it breaks the carriage return (instead of going to a new line when line is full, it starts in the same line and erases the input text).  If I remove the color sequence it works fine. I use Ubuntu 11.10 and terminal (guake has the same bug too). I'd really like to learn how to play pen-and-paper RPGs.  I know that it takes a few players to actually sit down and play, but I'm not at all sure where to find more gamers.  How do I find existing groups to join? Or, are there any resources online that may help me find existing RPG groups or players? Generate dynamic XY coordinate labels for dataframe corners in ArcGIS layout I need to label the four corners of a dataframe as shown in the image. Can this be done with dynamic text scripts? How are POST and GET variables handled in Python? In PHP you can just use $_POST for POST and $_GET for GET (Query string) variables. What's the equivalent in Python? How to install qt 4.8 from repository? I'd like to copy files from one external drive to a network connected drive. I want to make sure that there are no errors.  I know of MD5 hash files that I see for large single files that are download from the internet. I also know that I can use the terminal to 'diff' the two sets of files.  However, I'm looking for a piece of software that could confirm that all the files in the file structure have been copied by the finder completely, or a piece of software that would do the copying for me and confirm that all the bits are exactly the same.  The files are video related - and are often over a TB in size (not in one file - complex multi-folder nested files)  I'm fine if there is a terminal command that can do the copy and compare for me as well. (although being able to see the amount of time left on a copy is a very nice feature... additionally, I want to make sure I get ALL of the file - resource forks and all) Question is pretty much in the title: is it possible for an alliance to win as one, instead of a single player being the winner?  And if there is such way, is there a difference between classic and disharmony? How to implement an abstract class in ruby? I know there is no concept of abstract class in ruby. But if at all it needs to be implemented, how to go about it? I tried something like...  class A   def self.new     raise 'Doh! You are trying to write Java in Ruby!'   end end  class B &lt; A   ...   ... end   But when I try to instantiate B, it is internally going to call A.new which is going to raise the exception.  Also, modules cannot be instantiated but they cannot be inherited too. making the new method private will also not work. Any pointers? There is an UI issue for the ranking div when a user crossed 200 reputation When a user just crossed 200, or 200+ reputation, the ranked div (i.e., top 10% overall) is trying to display. But rank calculation can be done on end of the UTC day. So instead of the ranking div, there is a blue colored hyphen is visible to users, it may be the initial loader for the ranking div.  I saw this UI issue previously too for the same scenario. Can this be fixed? Can you explain briefly the main concepts and command line tools used to manage file permissions? I have complicated math expression:    Vertical spacing between text and fraction line is too small. I tried to define new \frac command (with amsmath package) with adjustable vertical spaces. As you can see, the result is not satisfying:    \documentclass[a4paper,fleqn,leqno]{article} \usepackage{polyglossia} \usepackage{color,pifont,fontspec} \usepackage[top=2.54cm,bottom=2.54cm,left=2.54cm,right=2.54cm]{geometry} \usepackage{tikz,tikz-3dplot,graphicx} \usepackage{mathtools,breqn,amsmath} \usepackage[fontsize=12]{scrextend} \usepackage{array,multirow} \usepackage{pgfplots} \DeclareMathSizes{12}{14}{14}{10} \newcommand{\myfrac}[3][0pt]{\genfrac{}{}{}{}{\raisebox{#1}{$#2$}}{\raisebox{-#1}{$#3$}}} \begin{document} \begin{dmath*}[breakdepth={0},style={\mathindent=0pt},spread={10pt}] {n=\myfrac[3pt]{\myfrac[3pt]{0,0625N+0,0215}{2}-0,043}{\myfrac[3pt]{\myfrac[3pt]{\scriptstyle 0,0625N+0,0215}{\scriptstyle 2}-0,043}{\myfrac[3pt]{\scriptstyle N}{\scriptstyle 2}-1}+0,0215}} \end{dmath*} \end{document}   How can I enlarge verticall spacing in whole fraction? How to create posters using LaTeX Let $p$,$\ q$ be prime numbers and $n\in \mathbb{N}$ such that $p \nmid n-1$. If $p \mid n^q-1$, then $q \mid p-1$. Surface of genus $g$ does not retract to circle (Hatcher exercise) Is there a way to set transparency of windows in GNOME? I replaced a non-protected receptacle with a GFCI type and now my circuit tester trips the GFCI as soon as it is plugged in.  The receptacle tested fine before replacement, ground, neutral, hot, etc.  I've double checked the hot/neutral/ground connections.  I've also tried it with the downstream load disconnected.   The GFCI trips the moment I plug in my circuit tester (before pushing the test button).  Otherwise things check out OK.  I can plug in a power tool without it tripping.  Also, the integrated test/reset button work correctly.   I've read that the integrated test button is the only one that truly matters. Is this correct or should I be concerned? I'm sure a home inspector will red flag this if their tester has the same result.  Update  My tester is by "Commercial Electric".  The tester is one of the palm sized three prong type with three leds to indicate the condition of the circuit and a button on top to test GFCI. It's new from the local box store. I understand that division by zero isn't allowed, but we merely just multiplied $f(x) = 1$ by $\frac{x-1}{x-1}$ to get $f(x) = \frac{x-1}{x-1}$ and $a\cdot 1 = 1\cdot a = a$ so they're the same function but with different domain how is this possible?  Or in other words why don't we simplify $f(x) = \frac{x-1}{x-1}$ to $f(x) = 1$ before plotting the points. Is it just defined this way or is there a particular reason ?  Note: my book says the domain of $f(x) = 1$ is $\mathbb{R}$ and the domain of  $f(x) = \frac{x-1}{x-1}$ is $\mathbb{R}$ except $1$. Finding a tricky limit Is there an easy way to TeX geometric pictures?
