Set default home page via  in JSF project What cause the "from review" links to appear in comments? I sometimes see comments ending in "From Review" (hyperlinked to a review page) on questions and answers, e.g.        I spend a good bit of time in the review queues (on Unix &amp; Linux), but comments I make do not come with these "From Review" links. Note that I only have access to the "First post" and "Late answer" queues.  Do these links only appear for the higher-rep queues? Is there a regular expression to detect a valid regular expression? Is there anything canon in the Terminator Universe that picks up where Terminator: The Sarah Connors Chronicles leaves off? So, Terminator canon is pretty twisted, given all that time-travel stuff.  But in the canon that includes the T:SCC, does anything pick up where the show left off that is considered canon? I would like to set the wallpaper in the login screen (Unity Greeter), how do I do that? How to find the smallest $n$ such that $n^a\equiv 1 \pmod p$ Given a prime $p$ and number $a$, how do I find the smallest $n$ such that $n^a\equiv 1 \pmod p$? Is there a non trial-and-error method?  Edit: obviously removing $n=1$! Suppress Chrome 'Failed to load resource' messages in console Rings' second isomorphism theorem I am thinking about the proof of the second isomorphism theorem, and something isn't very clear to me.   Let $R$ be a ring, $S\subset R$ a subring and $I\subset R$ an ideal. We have the natural homomorphism $f:R\rightarrow R/I$. The theorem states that $\mathrm{Im}(S)=(S+I)/I$. My question is why not simply $\mathrm{Im}(S)=S/I$?  I understand that it is not true (for starters, $S/I$ need not be a subring), but I cannot explain that to my self in a convincing way. Show that $[0, 1)\times[0, 1)$ is homeomorphic to $[0, 1]\times[0, 1)$ but not to $[0, 1]\times[0, 1]$. When I sketch these spaces it this statement makes sense intuitively because $[0, 1]\times[0, 1]$ is closed and $[0, 1)\times[0, 1)$ and $[0, 1]\times[0, 1)$ are each "missing" part of their boundary which would make them closed. I also know, $[0, 1]\times[0, 1]$ is compact and compact spaces are not homeomorphic to non-compact spaces.   I am having trouble saying this explicitly, as is pretty obvious in the clumsiness of the wording above. Convert string to Title Case with JavaScript Cycles: How do I exclude the Environment Texture from reflections? Need to print out iPhone text messages I have a court case and have text messages on my iPhone I need to transfer to my iPad email for evidence.

Problem with Refsection What's a command line way to find large files/directories to remove and free up space? Looking for a series of commands that will show me the largest files on a drive. During Winter Bash, users can earn hats. But sometimes it seems that a hat was awarded even though its requirements weren't (yet) met, or vice versa.  What could be the reason for this? Is there is any reason to make the permissions on an overridden C++ virtual function different from the base class?  Is there any danger in doing so?  For example:  class base {     public:         virtual int foo(double) = 0; }  class child : public base {     private:         virtual int foo(double); }   The  says that it is a bad idea, but doesn't say why.  I have seen this idiom in some code and I believe that the author was attempting to make the class final, based on an assumption that it is not possible to override a private member function.  However,  shows an example of overriding private functions.  Of course  recommends against doing so.  My concrete questions:   Is there any technical problem with using a different permission for virtual methods in derived classes vs base class? Is there any legitimate reason to do so? How can I get query string values in JavaScript? Add asterisk after labels in enumerate I would like to add an asterisk after certain labels in the enumerate environment. So for example  \documentclass{article} \begin{document}  \begin{enumerate}     \item Kuttel     \item* Daddeldu \end{enumerate}  \end{document}   but without the space between 2. und *. Extracting Data Between two Characters in Excel I have the following format in Excel and I am trying to extract the data between the characters:  First Last &lt;flastname@xxxx.com&gt;   I need to extract the email address between &lt; and > into its own cell  Thanks! Find where java class is loaded from Does anyone know how to programmaticly find out where the java classloader actually loads the class from?    I often work on large projects where the classpath gets very long and manual searching is not really an option.  I recently had a  where the classloader was loading an incorrect version of a class because it was on the classpath in two different places.  So how can I get the classloader to tell me where on disk the actual class file is coming from?  Edit: What about if the classloader actually fails to load the class due to a version mismatch (or something else),  is there anyway we could find out what file its trying to read before it reads it?
