How to speed-up make-based building process

If you are building some multifile-based project using make tool, it is worth to use parallel build in order to speed up building process.

You can do that using -j option of make tool ex.

make -j2

If you will select -j2, you are informing your compiler to use 2 cores of your CPU for building process.

The optimal option is to split build using all cores of your CPU. In order to get number of cores of your CPU on Linux-based OS you can use command:

nproc

Therefore, if you would like to speed-up build time optimally using all cores of you CPU, you can use following command on Linux-based OS:

make -j`nproc`

Advanced C++ - Stack unwinding

Stack unwinding is normally a concept of removing function entries from call stack (also known as Execution stack, Control stack, Function stack or Run-time stack). Call Stack is a stack data structure that stores active functions' addresses and helps in supporting function call/return mechanism. Every time when a function is called, an entry is made into Call stack which contains the return address of the calling function where the control needs to return after the execution of called function. This entry is called by various names like stack frame , activation frame or activation record. With respect to exception handling , stack Unwinding is a process of linearly searching function call stack to reach exception handler. When an exception occurs, if it is not handled in current function where it is thrown, the function Call Stack is unwound until the control reaches try block and then passes to catch block at the end of try block to handle exception. Also, in this proc...

Boost - shared pointer

Shared pointer is another kind of Boost library's pointer. It is similar to scoped pointer but shared pointer allows share ownership of object. We are able to assign two or more pointers pointing to the same object (it was impossible for scoped pointer). Take a look to the example below: Output of this example is: In point I we are initializing two shared pointers pointing to two separate instances of TestClass class, then we are printing its values in point II. Point III shows use difference between shared pointer and scoped pointer. We are assigning two pointers to the same object of class TestClass . In this point object having testValue==5 is being destroyed (because we remove the only one pointer to that object). Also, we have two pointers pointing to objects having testValue==6 now. Note that that object will be destroyed when last shared pointer pointing to them will be destroyed ( int our case it is destroyed when we are reaching end of main() function)...
