Mobile App Monetization Strategy: 9 Models To Choose From

A medical mobile app should complement the overall business goals of the app’s owners. It’s best to integrate a mobile app monetization strategies at the beginning rather than force one when your app is already built and functioning with an active user base. An app’s optimal monetization model highly depends on its business logic and concept.

user behavior – App that synthesizes text. You can choose the outcome size only during the first 2 of the 4 steps process. How do I make it clear?

I am working on an app that synthesizes long texts, articles, essays.
You paste in the text and the system starts synthesizing.
You can choose a size of the final format, say Short, Medium, Elaborate only during the first 2 steps of the 4 steps process.
How do I make it clear that the user can only do that during the first 2 steps?
Yes, we could ask the question before the user clicks Start but we wanted to make it as quick as possible, upload and hit Start. then you can choose..

Which gaming laptop should I choose?

I am planning to buy a laptop or PC. Can you recommend me some smooth gaming computers?
How much RAM is enough? How often will the system upgrade? Is Macbook gaming good?

What kind of computer play the game well?

design – How to choose between those different options for communicating between objects?

I have a few objects that should communicate between each other. I also want to have my code unit tested.
I am questioning how I should handle their communication:

  • Should I make one instantiate the other one?
  • Should I pass one in the constructor of the other one?
  • Should I make them communicate via events/a observable pattern?

What criteria should I use to choose between those options?

To illustrate this, let me give an example for each one of those approaches:


Example of one object instantiating another one

Code Sample:

public class Restaurant
{
    private Kitchen _kitchen;

    public Restaurant()
    {
        this._kitchen = new Kitchen();
    }

    public void Prepare(Order order)
    {
        foreach(Meal meal in order.Meals)
            this._kitchen.Cook(meal);
    }
}

public class Kitchen
{
    public void Cook(Meal meal)
    {
         // cooking magic goes here
    }

}

public class App
{
    public void Main()
    {
        Restaurant restaurant = new Restaurant();

        restaurant.Prepare(new Order());
    }
}

Pros:

  • App does not know about Kitchen

Cons:

  • Unit testing Restaurant now requires testing for the behavior produced by Kitchen

Example using dependency injection via constructor

Code Sample:

public class Restaurant
{
    private ICooker _cooker;

    public Restaurant(ICooker cooker)
    {
        this._cooker = cooker;
    }

    public void Prepare(Order order)
    {
        foreach(Meal meal in order.Meals)
            this._cooker.Cook(meal);
    }
}

public class Kitchen: ICooker
{
    public void Cook(Meal meal)
    {
         // cooking magic goes here
    }

}

public interface ICooker
{
    void Cook(Meal meal);
}

public class App
{
    public void Main()
    {
        Kitchen kitchen = new Kitchen();
        Restaurant restaurant = new Restaurant(kitchen);

        restaurant.Prepare(new Order());
    }
}

Pros

  • Kitchen can be unit tested separately from Restaurant.
  • Inversion of control

Cons:

  • App now has to know how to instantiate Kitchen.
  • There is still some coupling between Restaurant and Kitchen.
  • Mocking is necessary when unit testing Restaurant

Example using dependency via events

public class Restaurant
{
    public event Action<Meal> Cooked;

    public void Prepare(Order order)
    {
        foreach(Meal meal in order.Meals)
            this.Cooked?.Invoke(meal);

    }
}

public class Kitchen
{
    public void Cook(Meal meal)
    {
         // cooking magic goes here
    }

}

public class App
{
    public void Main()
    {
        Kitchen kitchen = new Kitchen();
        Restaurant restaurant = new Restaurant();

        restaurant.MealCooked += kitchen.Cook;

        restaurant.Prepare(new Order());
    }
}

Pros:

  • Removes the necessity of mocking when unit testing Restaurant
  • Makes Restaurant and Kitchen really decoupled.

Cons:

  • App not only has to know how to instantiate Kitchen but also has to connect the related events and listeners.

Question

Is there a preferable approach? What criteria should I use to choose between those options?

linux – Opensuse Standard vs Port – which one to choose to install mariadb-connector-c

I knew that the openSUSE OS versions are either Tumbleweed or Leap. We have openSUSE Leap 15.1 installed.
Here is the system information:

NAME="openSUSE Leap"
VERSION="15.1"
ID="opensuse-leap"
ID_LIKE="suse opensuse"
VERSION_ID="15.1"
PRETTY_NAME="openSUSE Leap 15.1"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:leap:15.1"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"

Question is we need to install mariadb-connector-c but confused which one to choose Standard or Ports from here: https://software.opensuse.org/download/package?package=mariadb-connector-c&project=openSUSE%3ALeap%3A15.1%3AUpdate

enter image description here

Also what is the better way to install the library? Commands would be really helpful.
