Are all stack exchange badges the same and if so why?
Is it possible to have site-specific badges?
Why has the innkeeper put a price on my head? So, I was just assaulted by a trio of fairly well armed thugs while walking out of Riften. Before attacking me, they informed me that they were 'here to teach me a lesson.'  After dispatching them in due course, I found this on the body of what I can only assume to be the leader, given his vastly superior armaments:   Orgnar is the innkeeper in Riverwood. Now, I admit, I've stolen a fair amount, but I pride myself on having never been caught. My total bounty to date is at zero. So, how did he figure out that I stole something, why is he taking the law into his own hands, and if I go back to Riverwood, am I going to get shanked? Equidistant points across Bezier curves Have you ever had a case where you felt compelled to include strange things like a double that in a sentence? If so, then what did you do to resolve this?  For me, I never knew whether it was acceptable grammar. However, what I did learn was that it was a logic distractor, could lead to confusion, and therefore should be reworded to avoid this. update-java-alternatives vs update-alternatives --config java On Ubuntu 12.04 LTS I have installed Sun's JDK7, Eclipse, and the Arduino IDE. I want the Arduino to use OpenJDK 6 and want Eclipse to use Sun's JDK 7.   From my understanding I need to manually choose which Java to use before running each application. This led me to the update-java-alternatives -l command. When I run this I only see the following:   java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64   but when I run update-alternatives --config java I see the following:   *0  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   auto mode 1  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   manual mode 2  /usr/lib/jvm/jdk1.7.0/bin/java                   manual mode 3  /usr/lib/jvm/jre1.7.0/bin/java                   manual mode   I don't understand why the update-java-alternatives doesn't display the same 3 options. I also don't understand how to switch between OpenJDK6 and JDK7. How I can go about using the OpenJDK6 for Arduino development and Sun JDK7 for Eclipse/Android development? Page-wide table in two-column mode I want a table that is as wide as the whole page in a document with option twocolumn. The table has to be inserted on the bottom of the page, but that is not necessary.  I've tried:  \begin{table*}[b]   ... \end{table*}   But that puts the table at the end of the document instead of on the same page.  I also tried:  \twocolumn[   \begin{table}[b]     ...   \end{table} ]   But that gives me an error: ! Argument of \@xfloat has an extra }. Combining \twocolumn and the star mark gives the same error.  What's the right way to do this? How can I install Windows after I've installed Ubuntu? I have Ubuntu on my laptop.

Compute device list not showing card name when using OpenCL I have an AMD Radeon R7 M265, and when I force OPENCL with the batch file it only shows Iceland, Intel HD and the CPU.  I followed this instructions:   R, type CMD, press &#9166; Enter, go to your blender folder. ex:  cd C:\Program Files\Blender Foundation\Blender  Press &#9166; Enter and then type: set CYCLES_OPENCL_TEST=all Start Blender with blender.exe Inside blender go to File -> User preferences -> System Under compute device select OpenCL and then your card Close the preferences and go to the render panel and select device: GPU Compute.  I have the latest beta driver from AMD, but when I try to change the compute device it only shows this list:     Am I doing something wrong? Is my GPU is not supported? Or is it because it's in development and not every card is supported yet?  I've tried blender v2.74.5, v2.62, and v2.63. Every one gives the same list. From the Immediate Window in Visual Studio:   &gt; Path.Combine(@"C:\x", "y") "C:\\x\\y" &gt; Path.Combine(@"C:\x", @"\y") "\\y"   It seems that they should both be the same.    The old FileSystemObject.BuildPath() didn't work this way... Does the sum of reciprocals of primes converge? Is this series known to converge, and if so, what does it converge to (if known)?

The database stopped for no apparent reason. I just did a restart of mysql server to solve the issue but after a simple update I got some errors on mysql-server package. The update was for other packages and not mysql-server package. Mysql still stops at least once a week and each time I have to restarts the mysql-server.  Can some one help me to understand the error please ?  Here the result of: dpkg --configure -a  Configure mysql-server-5.7 (5.7.23-0ubuntu0.18.04.1) ... /var/lib/dpkg/info/mysql-server-5.7.postinst: ligne 191: /usr/share/mysql-common/configure-symlinks: no file or folder  dpkg: erreur de traitement du paquet mysql-server-5.7 (--configure) : installed mysql-server-5.7 package post-installation script subprocess returned error exit status 127 Installing other fonts on wine Cell copy results in jaggy, aliased output I've been working through a bit of Ireland and Rosen's Number Theory for fun. Problem 4.11 of Ireland and Rosen asks     Prove that $1^k+2^k+\cdots+(p-1)^k\equiv 0\pmod{p}$ if $p-1\nmid k$, and $-1\pmod{p}$ if $p-1\mid k$.    My work is leading where I didn't expect to go. Here I assume $p$ id odd. First, if $p-1\mid k$, then we can wrike $k=(p-1)j$ for some $j$. But then $$ 1^k+\cdots+(p-1)^k\equiv 1^{(p-1)j}+\cdots+(p-1)^{(p-1)j}\equiv \underbrace{1+\cdots+1}_{p-1\text{ times}}=\frac{(p-1)p}{2}\equiv 0\pmod{p} $$ since $p-1$ is even.   Secondly, I suppose $p-1\nmid k$. WLOG, I can assume $0&lt;k&lt;p-1$, Since if $k=(p-1)j+r$ with $0&lt;r&lt;p-1$, then  $$ a^k\equiv a^{(p-1)j+r}\equiv a^r\pmod{p}. $$  Then if $g$ is a primitive root, $$ 1^k+\cdots+(p-1)^k=\sum_{i=1}^{p-1}(g^k)^i=\frac{g^k(1-g^{k(p-1)})}{1-g^k}. $$ Since $g$ is primitive, $p\nmid 1-g^k$, but $p\mid 1-g^{k(p-1)}$, so the above sum is again congruent to $0\pmod{p}$.  So in all cases, I get the sum is congruent to $0$ regardless. Have I messed up, or is there a typo? Thanks.

Fantasy book where a young prince becomes a mage Can I purge configuration files after I've removed the package? I was doing a package removal with apt-get remove but then realized I should have done a --purge along with it to remove the configuration files.  Can I remove the packages configuration files easily or do I need to reinstall the package and then remove with a --purge? SQL Server 2012 and 2016 Standard:  If I put if-else logic in a stored procedure to execute one of two branches of code, depending on the value of a parameter, does the engine cache the latest version?  And if on the following execution, the value of the parameter changes, will it re-compile and re-cache the stored procedure, since a different branch of the code must be executed? (This query is quite expensive to compile.)
