Internal typedefs in C++ - good style or bad style?
...hat it does not do.
If I see 'Foo::Ptr' in the code, I have absolutely no idea whether it's a shared_ptr or a Foo* (STL has ::pointer typedefs that are T*, remember) or whatever. Esp. if it's a shared pointer, I don't provide a typedef at all, but keep the shared_ptr use explicitly in the code.

How to hide action bar before activity is created, and then show it again?
...me extra logic to check if this is the first showing of the Activity.
The idea is to delay a little the hiding of the ActionBar. In a way we let the ActionBar be shown, but then hide it immediately. Thus we go beyond the first non-animated showing and next showing will be considered second, thus it...

When to use a View instead of a Table?
... simple count(*) of the records. Views calling views are an extremely poor idea.

...
It's not a great idea to add a dependency on a ~70k 3rd party library just to do this, since the same thing can be accomplished in just a few lines of code as shown in the other answers here. However, if you are already using jQuery on your ...
