GE Acquires Wise.io to Accelerate Machine Learning Efforts

GE have just announced a deal that saw its GE Digital division snapping up the machine learning startup Wise.io in a deal that has been kept so far quite quiet. The company has acquired Wise.io in an attempt to strengthen its own deep learning techniques with the business. They will also be looking to have the team from Wise make improvements to their own Digital Twin services that are focused on the Internet of Things (IoT) [read more ... and more ...].

Default Class Accessibility in C#

Default Class Accessibility in C#

There are two rules for Default Class Accessibility in C# as in the following:

1. Top-level classes, which are not nested in other classes, can only have internal or public accessibility. The default accessibility for these classes is internal.

2. Nested classes, which are members of other classes, can have declared accessibility as indicated in the following table.

Members of	Default member accessibility	Allowed declared accessibility of the member
enum	public	None
class	private	public  protected  internal  private  protected internal
interface	public	None
struct	private	public  internal  private
