This program assigns a new object of class A to reference a. It looks as expected, reference changes to new object ( see line 23,24,25): #include <iostream> using namespace std; class A { string name; public: A(string n): name(n) { } A(): name("NO ONE") { } void print() { cout << "I am "<< name << "!"<< endl; } }; int main(int argc, char *argv[]) { A matrix = A("the matrix"); A &a = matrix; a.

The most promising tools I found are SCons, CMake and Waf ( little brother of SCons ) SCons is written in Python and very extensible, but it might be slow for other large projects [1]. CMake is written in C++, is faster than SCons but is arguably not as extensible as SCons [1]. [1] Evalutation of various build tools Here is another article: Battle of the build systems

How does live linux disk work without any swap for applications bigger than available RAM? This question has occurred to me a lot of times. In the normal scenario I configure enough swap space on the harddis for my GNU/Linux installation. It looks clear that whenever a new request for memory is made by an application, the Linux kernel (OS) gives that request by swapping out a page into swap space ( when there wasn’t enought space available in RAM).

Debugging Java Code jdb supports fairly primitive support for debugging, which is sufficient ( sort of ) when used as a backend for an IDE ( like NetBeans, Eclipse etc. ). However when I compare it with GDB ( the GNU Debugger ), as a tool to be used on the terminal, it seems to be pretty old. JDB lacks in features and commands which GDB specializes in. I was mainly interested in abbreviation of commands.
Branching and Merging Creating a branch: git checkout -b branch-name OR git branch branch-name git checkout branch-name Example: $ git branch rm123 $ git checkout rm123 Merging a branch: $ git checkout master $ git merge rm123
