The only thing was that it was a bit confusing cause you used the names John and Bob in place of girl names, so that threw me off a bit .
Haha, nice story.

If you can't delete it, you might be able to rename it, but I'm not sure why some locked files can.

Is there any way in Python to determine what exceptions a (built-in) function might raise? For example, the documentation ( http://docs.python.org/lib/built-in-funcs.html ) for the built-in int(s) says nothing about the fact that it might raise a ValueError...

The fact that the int() documentation doesn't say it may raise ValueError is a bug in the documentation... .
The only way to tell what exceptions something can raise is by looking at the documentation .
I don't know of any definitive source, apart from the source .

If you have
Parent has_many :children Child
Is there any reason a foreign key on Child (to Parent) and a corresponding belongs_to :parent might not be desirable?
When, if ever, would you not want your Child to be able to access its parent?

It's a trade-off.
You can still access the parent record (assuming you have a parentID column in the child table, just no referential integrity) .
There is a cost when inserting a child record to determine if there is a parent record .
Performance.

I might be missing something obvious but is there a reference somewhere about what exceptions are thrown by functions in .NET and why the exception might be thrown?
As an example, I was recently trying out Linq in Visual C# 2008 and I was loading an XML...

EDIT: if you look at the Namespace doco (for System.IO for instance) it lists possible thrown exceptions .
NET does not implement anything like the 'throws' keyword in java, so your best bet is to check the online MSDN documentation .

Why might using a "long long" in C or C++ be a bad thing?
I was compiling a runtime library the other day and in the code it checks to see if longs are 64bits and if not it uses a long long. But along with that, it sends out a #warning "using long long...

Answer Snippets (Read the full thread at stackoverflow):
If you use an old C compiler, it might not support long long one might use the C99 header <stdint.h> , or in C++ <boost/cstdint.hpp>
It isn't.
That it is exactly 64 bits, there could be a problem .

The entities are:
Post: ID, Post Type (Question or Answer), Text, User ID Question extends Post: Title Answer extends Post: Comment: ID, Post ID (attached to which Post), User ID, Text
And you can extend this easily... .
This is a fairly obvious structure.
