In the build.sbt file (or where the project is defined if it is in another location), add the following setting:

For instance, a project might be defined like this:

When the last command in an interactive bash instance is done, the evaluated PS1 variable is displayes. Before actually displaying PS1 bash looks whether the PROMPT_COMMAND is set. This value of this var must be a callable program or script. If this var is set this program/script is called BEFORE th...
PS2 is displayed when a command extends to more than one line and bash awaits more keystrokes. It is displayed too when a compound command like while...do..done and alike is entered.
export PS2="would you please complete this command?\n"
# now enter a command extending to at least two l...
When the select statement is executed, it displays the given items prefixed with a number and then displays the PS3 prompt:

SharePoint 2013 and newer versions are 64-bit only and so the assembly/program needs to be also built for 64-bit processor.
Right after your project is created it is necessary to swich the Platform target from Any CPU to x64 otherwise error will occure.

Using async initialization is a recommended way for application development. It uses the OpenCV Manager to access OpenCV libraries externally installed in the target system.
Code snippet implementing the async initialization:
public class MainActivity extends Activity implements CvCameraViewListen...
According to this approach all OpenCV binaries are included into your application package. It is designed mostly for development and debugging purposes. This approach is deprecated for the production code, async initialization is recommended.
If your application project doesn’t have a JNI part, jus...
Due to way that the float type is represented in computer memory, results of operations using this type can be inaccurate - some values are stored as approximations. Good examples of this are monetary calculations.
If high precision is necessary, other types should be used. e.g. Java 7 provides Big...

The whole point of MVVM is to separate layers containing logic from the view layer.
On Android we can use the DataBinding Library to help us with this and make most of our logic Unit-testable without worrying about Android dependencies.
In this example I'll show the central components for a stupid...

Encapsulating an OpenGL object in C++98/03 requires obeying the C++ rule of 3. This means adding a copy constructor, copy assignment operator, and destructor.
However, copy constructors should logically copy the object. And copying an OpenGL object is a non-trivial undertaking. Equally importantly,...
C++11 offers tools that enhance the functionality of RAII-encapsulated OpenGL objects. Without C++11 features like move semantics, such objects would have to be dynamically allocated if you want to pass them around, since they cannot be copied. Move support allows them to be passed back and forth li...
