• Cocoa for the non-techinical

  - by annoyed

  How would you describe and explain Cocoa in non-technical terms, with lots of analogies to common, everyday things. For example, imagine you are describing it to a 5-year-old who keeps asking why? at the end if each explanation. This would invariable delve into the theory of OO so it could get lengthy, but the concept is important to the 'why' of Cocoa.

Say for example I have an application X running on some OS, say Y, What do I do to port this application to another OS say Z? Does this mean rewriting a new application A for Operating system Z that necessarily imitates the behavior of application X on Operating System Y. Please explain.

• Backslashes in gsub (escaping and backreferencing)

  - by polygenelubricants

  Consider the following snippet: puts 'hello'.gsub(/.+/, '\0 \\0 \\\0 \\\\0') This prints (as seen on ideone.com): hello hello \0 \0 This was very surprising, because I'd expect to see something like this instead: hello \0 \hello \\0 My argument is that \ is an escape character, so you write \\ to get a literal backslash, thus \\0 is a literal backslash \ followed by 0, etc. Obviously this is not how gsub is interpreting it, so can someone explain what's going on? And what do I have to do to get the replacement I want above?

• why do i see THROW in a C library

  - by Bhagya

  When I do: less /usr/include/stdio.h (which is only a C library - nothing to do with C++) I see __THROW after quite a few function declarations. Also, comments above a few functions say that 'This function is a possible cancellation point and therefore not marked with __THROW' What is all this for? THROW is meant to be for exception handling.. but as far as I know, C doesn't provide any support for it... Plz explain.

  - by Zanneth

  Statically-typed languages and dynamically-typed languages in principle seem like opposite concepts. However, how can a language like Objective-C for example be both of these things at once? It seems to me that Objective-C is more static than dynamic. Can somebody explain how this is possible?
