Using Xcode for OpenCV projects

OpenCV is the most mature computer vision library in the world. Xcode is the best IDE on macOS. OpenCV is written in C++ and various bindings (first- and third-party) exist for most popular language. I prefer to work in C++. Although Xcode has excellent support for C++ projects, getting it to play nicely with OpenCV is rather tricky.


Kubernetes is a software system that allows one to easily deploy and manage containerised application on top of it. Its aim is to provide best possible utilisation of your hardware (metal and virtual) resources while still maintaining complete isolation of hosted applications.


When an application comprises a handful of large components only, it's completely acceptable to give a dedicated virtual machine (VM) to each component and isolate their environments by giving each their own operating system instance.

Comparing algorithms

Algorithms are instructions on how to perform a task. Not all algorithms are created equal. Some are fast, some are excruciatingly slow. Most algorithms are affected by the size of the input (typically denoted by n). The first step to improve code performance is to measure it.


A window is an instance of the UIWindow class and it is the topmost element of any application UI's hierarchy. It doesn't draw any visual object and can be considered as a blank container for the UI elements called views. An application must have at least one window that normally fills the entire screen.
