Start thread with member function
...td::cout << "hello from member function" << std::endl;
}
};
int main()
{
std::thread t(&bar::foo, bar());
t.join();
}
EDIT:
Accounting your edit, you have to do it like this:
std::thread spawn() {
return std::thread(&blub::test, this);
}

Conventions for exceptions or error codes
...
Your fourth point is not a fair one: An error status when converted into an object, can also contain code to check whether the file exists, or is locked, etc. It's simply a variation of stackoverflow.com/a/3157182/632951

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.

Learning to write a compiler [closed]
...lf and a bottom-one. The top-half generally takes the source language and converts it into an intermediate representation, and the bottom half takes care of the platform specific code generation.

Foreach loop, determine which is the last iteration of the loop
...plicate items. In this cases something like this may be more appropriate:
int totalCount = result.Count();
for (int count = 0; count < totalCount; count++)

Item result = Model.Results[count];
// do something with each item
if ((count + 1) == totalCount)
{

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).
Also: You probably want to do a: std::cin.clear(...
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...
