 echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

A PTRACE scope of "0" is the more permissive mode. A scope of "1" limits
PTRACE only to direct child processes (e.g. "gdb name-of-program" and
"strace -f name-of-program" work, but gdb's "attach" and "strace -fp $PID"
do not). The PTRACE scope is ignored when a user has CAP_SYS_PTRACE, so
"sudo strace -fp $PID" will work as before. For more details see:
https://wiki.ubuntu.com/SecurityTeam/Roadmap/KernelHardening#ptrace

//first example
//int main()
//{
//    int a=0;
//    cin >> a;
//    cout << "Hello World!" << endl;
//    return 0;
//}

//second example
//int main(int argc, char **argv)
//{
//    Mat im = imread("image.jpg", CV_LOAD_IMAGE_COLOR);
//    namedWindow("Hello");
//    char c;
//    imshow("Hello", im);
//    cout << "Press 'q' to quit..." << endl;
//    //cin >> c;
//    while(1)
//    {
//        c=waitKey(1000);
//    //    cout<<c<<" ";
//        if(((char) c) == 'q') break;
//    }
//    destroyAllWindows();
//    return 0;
//}



//third example
//// Global variables
//const int slider_max = 1;
//int slider;
//Mat img;

//// Callback function for trackbar event
//void on_trackbar(int pos, void *)
//{
//Mat img_converted;
//if(pos > 0) cvtColor(img, img_converted, CV_RGB2GRAY);
//else img_converted = img;

//imshow("Trackbar app", img_converted);
//}


//int main()
//{
//img = imread("image.jpg");

//namedWindow("Trackbar app");
//imshow("Trackbar app", img);

//slider = 0;

//createTrackbar("RGB <-> Grayscale", "Trackbar app", &slider, slider_max, on_trackbar);
//while(char(waitKey(1)) != 'q') {}

//return 0;
