First your OpenCV should be compiled with CUDA (and OpenGL) support to test all this features. Detect your CUDA hardware with OpenCV CUDA by:

#include <iostream>
using namespace std;

#include <opencv2/core.hpp>
using namespace cv;

#include <opencv2/cudaarithm.hpp>
using namespace cv::cuda;

Tailwind CSS best practices

Utility classes

1. When writing a string of multiple utility classes, always do so in an order with meaning. The "Concentric CSS" approach works well with utility classes (i.e,. 1. positioning/visibility 2. box model 3. borders 4. backgrounds 5. typography 6. other visual adjustments). Once you establish a familiar pattern of ordering, parsing through long strings of utility classes will become much, much faster so a little more effort up front goes a long way!

2. Always use fewer utility classes when possible. For example, use mx-2 instead of ml-2 mr-2 and don't be afraid to use the simpler p-4 lg:pt-8 instead of the longer, more complicated pt-4 lg:pt-8 pr-4 pb-4 pl-4.

3. Prefix all utility classes that will only apply at a certain breakpoint with that breakpoint's prefix. For example, use block lg:flex lg:flex-col lg:justify-center instead of block lg:flex flex-col justify-center to make it very clear that the flexbox utilities are only applicable at the

This gist aims to explain the difference between stubs and mocks and when each should be used. For an introduction to stubs and mocks, start somewhere else, like here.

 

• Stub: used to isolate the object under test from its dependencies, preventing the test from being influenced by code outside the object. This way the test can't be made to fail or be broken by code which is not part of the specific functionality being tested. Stubs also lead to less code being run, which helps keep tests fast. A stub has no expectations. It doesn't care if it is called or how many times.

  For example, you might stub out a message sent to a database connection if all you are trying to test is the type of the method's return value.

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.
