Declaration/definition of variables locations in ObjectiveC?
...d properties can be declared.
Before "modern" Objective-C (in "old" Obj-C 2.0) you didn't have a lot of choices. Instance variables used to be declared in the header between the curly brackets { }:
// MyClass.h
@interface MyClass : NSObject {
int myVar;
}
@end
You were able to access these v...
ASP.NET Identity DbContext confusion
...dditional items here as needed
}
To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.
Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from ...
Best practices/guidance for maintaining assembly version numbers
...ly Version but to set all the values in the File Version. For example:
1.2.0.0 (AssemblyVersion)
1.2.3.4 (FileVersion)
This gives you the ability to roll out hot fixes which will not break existing code because the assembly versions do not match but allow you to see the revision/build of an asse...
Why isn't `int pow(int base, int exponent)` in the standard C++ libraries?
... number and n equal to 10. In this scenario, pown_l won. glibc pow() took 12.0 user seconds, pown took 7.4 user seconds, and pown_l took only 6.5 user seconds. So that's not too surprising. We were more or less expecting this.
Then, I let x be constant (I set it to 2.5), and I looped n from 0 to 19...
In C++, is it still bad practice to return a vector from a function?
...::accumulate(v.begin(), v.end(), sum); by for (int k : v) sum += std::sqrt(2.0*k);:
Conclusions
Using output parameters instead of returning by value may provide performance gains by re-using capacity.
On a modern desktop computer, this seems only applicable to large vectors (>16MB) and smal...
Do zombies exist … in .NET?
...ments may be valuable to readers.
Immortal Blue pointed out that in .NET 2.0 and up finally blocks are immune to thread aborts. And as commented by Andreas Niedermair, this may not be an actual zombie thread, but the following example shows how aborting a thread can cause problems:

Can C++ code be valid in both C++03 and C++11 but do different things?

Why are C# 3.0 object initializer constructor parentheses optional?
...might change the syntax so that it is not ambiguous. When they designed C# 2.0 they had this problem:
yield(x);
Does that mean "yield x in an iterator" or "call the yield method with argument x?" By changing it to
yield return(x);
it is now unambiguous.
In the case of optional parens in an o...
