    git branch message auto
    In general, when I merge a branch from the master branch git automatically generates a commit message like this :Merge branch ‘master’ into name-of-my-branchbut last time it generates a commit message like :Merge branch ‘master’ of git.domain.com:repo-nameWhat caused this unexpected merge commit message?

    c++ reference c++11 copy-constructor auto
    I have some complex template code where the copy-constructor of OPC is being called even though I am only creating a reference to OPC (the actual instance is OP_S, which as a child class of OPC, should not result in a copy-construction call).I am using gcc 4.6.1The code is below.#include <stdio.h>class OPC {public:OPC() { }OPC( const OPC& f ) {fprintf( stderr, “CC called!!!\n” );} };template<class T> class SL : public T { };template<class T> class S : public SL<T> { }

    mysql table optimization index auto
    I noticed that MySQL automatically performs ‘OPTIMIZE TABLE’ on all of the tables. I am not sure why this is happening or how I could prevent it. The operation takes forever because I have a very large table and it locks it, preventing any other operations. If I cancel the optimize process, the table crashes and I have to repair it. This started happening after I wanted to add a FULLTEXT index on that table (but canceled the operation and then repaired the table).I have a standard install of MyS

    I am using Visual Studio 2010 with SP1. The following code crashes the compiler:template <typename T> class MyClass { public:typedef int my_int;const my_int foo();};template <typename T> const auto MyClass<T>::foo() -> my_int // auto MyClass<T>::foo() -> const my_int // THIS WORKS! {return my_int(1); }int main() {MyClass<int> m;m.foo(); }Note the commented line that fixes the issue. Am I using auto properly here (i.e. const qualifier on auto)? Is the workaroun
