Jackson overcoming underscores in favor of camel-case
...
You can configure the ObjectMapper to convert camel case to names with an underscore:
objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
Or annotate a specific model class with this annotation:
@JsonNaming(PropertyNamingStrategy.SnakeC...
Is inline assembly language slower than native C++ code?
... assembly you have to make well-defined functions with a well-defined call interface. However they can take in account whole-program optimization and inter-procedural optimization such
as register allocation, constant propagation, common subexpression elimination, instruction scheduling and other c...

GetType() can lie?
...c class BadFoo
{
public new Type GetType()
{
return typeof(int);
}
}
with this class (and using the sample code from the MSDN for the GetType() method) you could indeed have:
int n1 = 12;
BadFoo foo = new BadFoo();
Console.WriteLine("n1 and n2 are the same type: {0}",

Produce a random number in a range using C#
...
You can try
Random r = new Random();
int rInt = r.Next(0, 100); //for ints
int range = 100;
double rDouble = r.NextDouble()* range; //for doubles
Have a look at
Random Class, Random.Next Method (Int32, Int32) and Random.NextDouble Method

Elegant way to combine multiple collections of elements?
...llections, each containing objects of the same type (for example, List<int> foo and List<int> bar ). If these collections were themselves in a collection (e.g., of type List<List<int>> , I could use SelectMany to combine them all into one collection.

Guid is all 0's (zeros)?

Does it compile into the same IL as default(S) or are there any subtleties I'm missing?

When to use “new” and when not to, in C++? [duplicate]
...ed when it goes out of scope. Some examples of this are:
void foo()
{
Point p = Point(0,0);
} // p is now destroyed.
for (...)
{
Point p = Point(0,0);
} // p is destroyed after each loop
Some people will say that the use of new decides whether your object is on the heap or the stack, but tha...

What's the difference between passing by reference vs. passing by value?
...to it, I'll change the caller's variable itself, not e.g. whatever it is pointing to if it's a pointer.
This is now considered bad practice (as an implicit dependency). As such, virtually all newer languages are exclusively, or almost exclusively pass-by-value. Pass-by-reference is now chiefly use...
