What are the differences between struct and class in C++?
...erything is public.
Being public by default is generally considered a bad idea when taking an object-oriented approach, so in making a form of C that is natively conducive to OOP (you can do OO in C, but it won't help you) which was the idea in C++ (originally "C With Classes"), it makes sense to m...
One Activity and all other Fragments [closed]
... to manage the order of the fragments.
Never the less, it is quite a good idea, as if you need to create an app, where you want to show several views. By this idea, you'll be able to view several fragments in a single view..

JBoss vs Tomcat again [closed]
...Java EE application server:
When starting your project you should have an idea what it requires. If you're in a large enterprise environment JBoss (or any other Java EE server) might be the right choice as it provides built-in support for e.g:

@steveha: srepr is a very interesting idea. But I hold a different opinion than you on whether it needs to special-case str. Yes, str is by far the most obvious and common iterable that would cause an infinite recursion in srepr. But I can easily imagine user-def...
Building a minimal plugin architecture in Python
