I was interested to know blackhat Search Optimization help?

Can these Whitehat Tools advanced my rankings?

Love to hear your thoughts…

If it’s an implementation detail but used by several classes, put the @property declarations in a class extension in a separate file that includes your public header, e.g. put them in “MyClass_Private.h” which includes “MyClass.h”.

You can do this for private methods that you need to expose outside your class as well.

Why would you expose private properties or methods outside a class? Because it may have cooperating classes in the same module that need access, but you don’t want to expose those methods outside that module.

For example, you may expose just a view controller in some API, but the controller interacts with a bunch of private subviews in its implementation.

“To sum up:

Use @property to declare the state exposed by your objects. Use dot notation to get and set objects’ state. Use method declarations to declare the behavior exposed by your objects. Use bracket notation to invoke objects’ behavior.”

What about the case of state that you don’t really want exposed, since it’s private? Should we still use @property thereby making such state public, or forgo and handle it manually keeping it private?

It would be nice if dot syntax was restricted to @property accessors. Even better would be if dot syntax was expanded to include key-path functions like @count, @sum, and included [ ] indexed array access. If that happened, I’d be all in for using it as the primary way to access an object’s properties.

For example I may work with NSTableView in a way where it matters to me when it sends me notifications about changing selection, when it reload items, etc. — sometimes the documentation does not make these things clear so (despite attempts of avoiding it) I end up with assertions in my code about how Cocoa acts. This behavior may be wrong in some edge case or it may subtlety change in an OS upgrade.

So I very much want tests (and regression tests) for these things.

Are you doing any interface tests which would not be true in a normal execution of the application?

I wished that objects in Objective-C would also not have been so clearly linked to pointers (*), as in C, because an object is so much more than a pointer to a memory structure, conceptually. But, here I dwell off. Sorry.

In Oregon an “urban growth boundary” was implemented (at least around the Portland Metro area) and it seems to have worked quite well; center of city hasn’t fallen into burned out ignored buildings while urban sprawl happened. Instead, due to lack of build-able land, they tear down the old unwanted buildings and build newer taller ones (or restore them and add more stories on top).

We are also seeing an increase in residential density in a big way; many post world war II single story small homes on 4,000 – 5,000 sq ft lots getting torn down and replaced with three 2 or 3 story row-houses (3x density increase).

The one aspect of it that didn’t quite keep up was the need for really good mass transit to handle the higher density of people – that many cars just doesn’t work (!). We do have quite good mass transit, but they are rushing to catch up with the density growth – more light-rail lines, and streetcars going back in. It’s funny (and sad) that you can see the old (early 1900s?) street car rails under the asphalt they are digging up to put in the new street car rails.

Of course the developers seem to generally hate this urban growth boundary because it costs them more to tear down and rebuild.

I don’t know if it’s too late for Santa Clara, but maybe there is still the opportunity to establish a boundary like this there? Any small city with farmland/forest around it that can should implement one while that land is still unpaved/unlawnified.

I once wanted to go after a job at Apple, but my wife said something like, “I’m not moving to the State they PAVED” (obviously not the whole state, but as you note, much of the Cupertino/Santa Clara valley seems to have been paved).

Sad indeed.

Nothing a billionaire and a bulldozer couldn’t take care of I suppose…:-)

I couldn’t care less about living in an apartment and I prefer my “shitty” house any day .. apparently so do millions of others …

You are not me and no, we are not a collective … so lose that “we” …

Plan your own life for yourself.

Thanks for letting me know.

@Jason Morley: the problem you outline is not solved by boycotting the dot notation but by writing designated initializers or class methods (+ (id)personWithName: (NSString *)name), making name a private property and implementing a changeName method.
