Method Overloading for null argument
...
This is stated for Java 7. Does that also apply to previous Java versions? I mean: If you have several method signatures with parameters only along a type hierarchy, than you are on the save side with null as actual value? And if you have built a "hier...

Disabling contextual LOB creation as createClob() method threw error
...verifying if the DB supports some features and adjusting itself in case it doesn't. I would verify if any mapping is triggering this (like a LOB field), but it's nothing to worry about.

What is the purpose of “!” and “?” at the end of method names?
...es an exception.
Kernel::exit causes a script to exit, while Kernel::exit! does so immediately, bypassing any exit handlers.
Methods ending in ? return a boolean, which makes the code flow even more intuitively like a sentence — if number.zero? reads like "if the number is zero", but if number.ze...
What is the 'dynamic' type in C# 4.0 used for?
... decimal and double.
decimal foo = GetDecimalValue();
foo = foo / 2.5; // Does not compile
foo = Math.Sqrt(foo); // Does not compile
string bar = foo.ToString("c");
The second line does not compile because 2.5 is typed as a double and line 3 does not compile because Math.Sqrt expects a double. Ob...
Best Practices: Salting & peppering passwords?
...ing in another secret into the algorithm hasn't been studied at all.
That doesn't mean it is not safe. It means we don't know if it is safe. And the general recommendation with security and cryptography is that if we don't know, it isn't.
So until algorithms are designed and vetted by cryptographe...

The provided solution does not work for instances of types loaded from a remote assembly. To do that, here is a solution that works in all situations, which involves an explicit type re-mapping of the type returned through the CreateInstance call....
