Overhaul

As none of you have noticed (as I have no readers), I've given my blog a major overhaul. Along with a different look, I'm also now using SyntaxHighlighter which allows me to make some really pretty posts.

I've also renamed my blog from "Russell Harmon's Blog" to "Page Fault" in reference to what occurrs when you attempt to access a virtual address which is not resident in memory.

EDIT 2010-10-13: I appear to be working on yet another blog overhaul. This one is far from done. There must be something wrong with me.

Object Oriented C

So, thanks to blocks, Apple's new extension to C, you can now do basic object-orientation. Have a look over at github for a short example on how to do it.

To break it down, an object is a struct, which contains both fields and blocks which act as the object's methods.

typedef struct {
    Object super;
    char *_value;
    const char *(^getValue)();
    void (^setValue)( const char * );
} String;

This creates a String object which inherits from Object and has a field _value, and methods getValue and setValue.

Because this String's first field is an Object, it can be safely casted to one (upwards casting).

More to come... maybe.
