What's the difference between session.Merge and session.SaveOrUpdate?
... should use Merge() if you are trying to update objects that were at one point detached from the session, especially if there might be persistent instances of those objects currently associated with the session. Otherwise, using SaveOrUpdate() in that case would result in an exception.

Nullable type issue with ?: Conditional Operator
...nch of times already. The compiler is telling you that it doesn't know how convert null into a DateTime.
The solution is simple:

Note that Nullable<DateTime> can be written DateTime? which will save you a bunch of typing.

Can I use a binary literal in C or C++?
...rams as well (it is 100% preprocessor-driven.)
To do the converse (i.e. print out a number in binary form), you can use the non-portable itoa function, or implement your own.
Unfortunately you cannot do base 2 formatting with STL streams (since setbase will only honour bases 8, 10 and 16), but you...
Visual studio long compilation when replacing int with double
... can easily believe this.
The difference between IEEE standard floating point ops and the ones implemented by a processor often forces linking in library routines to do the translation, while integer math can just use the CPU instructions. At the time the IEEE defined the standard, they made some c...
How do I flush the cin buffer?

Possibly:
std::cin.ignore(INT_MAX);
This would read in and ignore everything until EOF. (you can also supply a second argument which is the character to read until (ex: '\n' to ignore a single line).
