Building and Compiling opencv 3.1.0-dev to get an access for non free modules can be a headache for some people especially on Windows machine. Unlike Ubuntu, setting up opencv for Windows takes some time and requires a couple pf dependencies to be installed first before building and compiling. Th...

Access platform specific API from PCL or Shared project.

For this process to work, the original error/exit code should start with 0x8007 which generally is an indication it originated from a valid Win32 process. However, should no message appear, then it probably didn't originate from a Windows process and therefore, will need to be examined further ou...

Create method: Create new record with specified value. Takes a number of field values, and returns a recordset containing the record created def create(self,vals): return super(class_name, self).create(vals) Write Method: Update records with given ids with the given field values.Takes a n...

A bounded context is subset of a large domain model. In larger domains, multiple teams will be working on multiple areas of the solution and this strategic pattern helps to share the work among the teams. The idea is to divide the big domain model in more focused areas, giving the team the freedom...

R = chol(A); [L,U] = lu(A); R = qr(A); T = schur(A); [U,S,V] = svd(A);

It became much easier to create custom controls in Interface Builder with the introduction of the @IBDesignable and @IBInspectable directives in Swift. Developers can now build rich, complex, fully animated controls using just a few extra lines of code. I'm surprised by how many developers have ye...

In modern C, header files are crucial tools that must be designed and used correctly. They allow the compiler to cross-check independently compiled parts of a program. Headers declare types, functions, macros etc that are needed by the consumers of a set of facilities. All the code that uses any ...
