I've just upgraded iTunes 11.1. On the first look it appears that the features of managing individual podcast download may had been broken. After some exploration, I've discovered that there is a new way of managing podcast. Listed below is some of the new interface I've discovered.  If you are using a list view for managing podcast, you'll be disappointed because you cannot manage individual podcast download here any more . You can only set the default podcast here. To set default podcast, click settings. and choose how you want the default podcast to be download. Previously, to manage individual podcast you need to select each podcast on the list and click settings. In iTunes 11.1 there is another way for you to manage each podcast. Please note that your previous  podcast settings is not lost . From the list view, you'll notice pages such as " My Podcasts " and " My Stations ". To manage individual podcast select " My P...

The following instructions is a simplified procedure to create a dynamic library. Please note that the actual implementation of dynamic library is very complex if the library is very large and multiple users or versions are involved. Please consult the Xcode user guide for more information. Example The following program is a complete program that uses some math functions: #include <stdio.h> #define PI 3.1415; double CircleArea (double radius); double CircleCircum (double radius); double PowerOf2 (double number); double PowerOf3 (double number); int main ( ) { double r = 4.0; double n = 5.0; printf ("Radius %.2f, area is %.2f \n", r, CircleArea(r)); printf ("Radius %.2f, circumference is %.2f \n", r, CircleCircum(r)); printf ("%.2f to the power of 2 is %.2f \n", n, PowerOf2(n)); printf ("%.2f to the power of 3 is %.2f \n", n, PowerOf3(n)); return 0; } double CircleArea (double radius) { return radius * radius * P...

For those who are not familiar with static and dynamic library, the differences between static and dynamic library is the way it was compile and run. To use a static library, the application and the static library must be present during compilation. The compiler will extract the code from the static library and incorporated into the application program. You'll have only one application binary file. When using dynamic library, the compiler do not incorporate the code from the dynamic library into the application program. The application program will load the library during runtime. In this case, you'll need to deliver two binary files to the user; the main application binary and the dynamic library file. The advantages of using dynamic library are smaller application size since the library code is not incorporated in the application program and it may reduce memory usage when since the library is loaded only when the function is needed. There are two usage of dynamic ...
