TCP vs UDP on video stream
...s clients is long due to the singularity of the event. Pre-recorded video-casts typically don't have as much of a problem with this because viewers stagger their replay activity; therefore TCP is more appropriate for replaying a video-on-demand.
IP multicast significantly reduces video bandwidth re...
What new capabilities do user-defined literals add to C++?
...ould have if these have been added to the language itself. We can even add cast operators (which is usually a bad idea, but sometimes, it's just the right solution).
We still missed one thing to have user-types behave as built-in types: user-defined literals.
So, I guess it's a natural evolution for...
Why do C++ libraries and frameworks never use smart pointers?
... to be readonly you can use a const reference (you can still do some nasty casts to be able to write the object) but you get the maximum of protection possible (it's the same with smart pointers).
But I do agree that it's much nicer to just return the object.

std::function vs template
...onst auto tp2 = high_resolution_clock::now();
const auto d = duration_cast<milliseconds>(tp2 - tp1);
std::cout << d.count() << std::endl;
std::cout << result<< std::endl;
return 0;
}
Update:
Added vs2015. I also noticed that there are double->fl...
Difference between method and function in Scala
...(def) m), or by a process called eta-expansion, which is like an automatic cast from method to function.
That is what the specs say, so let me put this up-front: we do not use that terminology! It leads to too much confusion between so-called "function declaration", which is a part of the program (...
OPTION (RECOMPILE) is Always Faster; Why?
...g a function for every row, your key matches don't use an index because of CASTING type conversion or NULLS or functions... Too many possibilities here.
In general when you write a query, you should have some mental picture of roughly how certain data is distributed within your table. A column f...
When should I use C++14 automatic return type deduction?
...n expressions they are usually implicit but we can make them explicit with casts". C++11 and C++1y introduce type deduction tools so that you can leave out the type in new places.
Sorry, but you're not going to solve this up front by making general rules. You need to look at particular code, and de...

Why can't C++ be parsed with a LR(1) parser?
...xed as:
int (MyClass::*)(char*) MethodPtr;
this being coherent with the cast operator (int (MyClass::*)(char*))
typedef int type, *type_ptr; could be forbidden too : one line per typedef. Thus it would become
