We can create a desktop application which will do registry changes, registration of assembly, creation of config files and all. Why dedicated installers are there?

• C++ passing arguments to a program already running

  - by wyatt

  I'm reading through a tutorial on using voice commands to control applications and, in an example of controlling rhythmbox, it suggests commands such as the following can be executed: rhythmbox-client --play rhythmbox-client --pause Why does this not simply open a new instance of the program, and how can I emulate the functionality in my own programs?

• Objective C @autoreleasepool directive

  - by Cemre

  I am reading a book which says (if I am not getting it wrong) wrapping some code with @autoreleasepool statement enables the ARC. First of all is this the case ? My second concern is when I am doing some iOS example programs, although I enable ARC when creating a new project, I never see this directive being used anywhere (in the automatically generated code). Does this mean that ARC is not being used ? Any ideas/pointers is appreciated.

Multithreading is sometimes not desirable as it will create serious impact on the way the actual program behaves. My question? I am not sure of when to use and when not to use multithreads in applications. Please update this thread and give your opinions on multithreading and suggestions on its usage scenarios.

• Sending information down a socket in C#

What purpose do the buffers serve for the sockets/streams? Apologies if I am a little vague.
