To implement the factory design pattern in Go, you can create a factory function that returns an object that implements a common interface. This function can take parameters to specify the type of object to be created. Here is an example of how you might implement the factory design pattern in Go: // Define an interface that the factory will create objects for type Animal interface { Speak() string } // Define a factory function that returns an object that implements the Animal interface func NewAnimal(animalType string) Animal { switch animalType { case "dog": return &Dog{} case "cat": return &Cat{} default: return nil } } // Define a struct for a dog that implements the Animal interface type Dog struct{} func (d *Dog) Speak() string { return "Woof!" } // Define a struct for a cat that implements the Animal interface type Cat struct{} func (c *Cat) Speak() string { return "Meow!" } // Use the factory function to create new Animal objects dog := NewAnimal("dog") cat := NewAnimal("cat") fmt.Println(dog.Speak()) // "Woof!" fmt.Println(cat.Speak()) // "Meow!" In this example, the NewAnimal() function is the factory function that returns objects of different types (Dog or Cat in this case) that implement the Animal interface. The factory function takes a string parameter that specifies the type of object to be created. The Dog and Cat structs both implement the Animal interface by implementing the Speak() method. The NewAnimal() function uses a switch statement to determine which type of object to return based on the animalType parameter. ...

Introduction This tutorial will show you how to create a simple theme in Hugo. I assume that you are familiar with HTML, the bash command line, and that you are comfortable using Markdown to format content. I’ll explain how Hugo uses templates and how you can organize your templates to create a theme. I won’t cover using CSS to style your theme. We’ll start with creating a new site with a very basic template. Then we’ll add in a few pages and posts. With small variations on that, you will be able to create many different types of web sites. ...

For my last project, I used poetry to manage dependencies and package my code. Poetry comes with all the tools you might need to manage your projects in a deterministic way. Anyway, after running poetry init in an existing project, I tried to let poetry create a virtuale environment, by adding the first dependecy, but when I did poetry add twisted it suddenly hang out, printing: No module named 'virtualenv.seed.via_app_data' Why is that? Because poetry was using the wrong virtualenv instance, so to solve this: ...

TLDR; I just unpaired the devices, then started a YouTube video on my Ubuntu machine and then repeated the steps below (pairing) while the audio was playing. At that point I’ve been able to send audio to my Echo Plus. Yesterday, I tried to use my Amazon Echo Plus as bluetooth speaker on my media center Running Ubuntu 20.04. I paired the Echo Plus using Alexa app on my phone following these steps: ...
