Snow Leopard Web Development Configuration
After installing Snow Leopard on my iMac I found I had to tweak some settings before I could continue my daily web development workflow. First, you should note Snow Leopard now comes with PHP 5.3 and it will overwrite your custom Apache configuration.
Here’s what I did to get up and running:

}
return base. _fooCache[arg];
};
This just keeps a local key/value cache of the result of the expensive operation for...

Awesome JavaScript memoization
Here’s an easy way to memoize expensive Javascript functions. It introduces slightly obscure code and an extra function call, but if your operation is expensive enough to memoize, it is probably worth the extra overhead:
this.foo = function(){
var foo = expensive_operation();
return (this.foo = function() { return foo; })();
};
What this function does is redefine itself, so on...
