Suppose I have a domain service which implements the following business rule / policy:

If the total price of all products in category 'family' exceeds 1 million, reduce the price by 50% of the family products which are older than one year.

Using collection-based repositories

I can simply create a domain service which loads all products in the 'family' category using the specification pattern, then check the condition, and if true, reduce the prices. Since the products are automatically tracked by the collection-based repository, the domain service is not required to issue any explicit infrastructure calls at all – as should be.

Using persistence-based repositories

I'm out of luck. I might get away with using the repository and the specification to load the products inside my domain service (as before), but eventually, I need to issue Save calls which don't belong into the domain layer.

I could load the products in the application layer, then pass them to the domain service, and finally save them again in the application layer, like so:

I need some design advice.

I have an application that will be reading data from various sources and doing checks and comparisons. My intention was to have all dependencies needed for data access (System.Data.SqlClient etc) contained within one set of Data Access classes (SqlImporter, JSONImporter etc.). Other classes that need data would then just use these classes to do the work. Perhaps they would pass a connection string or other information.

However, I needed to make unit tests for these Data Access classes. To make them testable, I made my Data Access classes rely on abstractions/interfaces and then pass in concrete implementations to allow me to pass in Mock objects from a unit test, similar to Mocking SqlConnection, SqlCommand and SqlReader in C# using MsTest.

The result is something like this:

When inheriting from a class, you have to use the super property to pass the arguments required to the constructor method of the parent class, therefore, you have to remember what are the required fields, so you'll to do the following for example:

I am creating an RShiny app that centres around a network drawn in ggiraph. The network is very large and detailed so ideally I'd like it to fill as much of the page as possible.

I've had a lot of problems getting ggiraph to scale properly, and also with margins/padding in RShiny. I've gotten this far with the code but it's still leaving huge amounts of whitespace

first of all What is extensible design?Is it a software architecture or a design approach in software?

Extensible design in software engineering is to accept that not everything can be designed in advance. A light software framework which allows for changes is provided instead. Small commands are made to prevent losing the element of extensibility, following the principle of separating work elements into comprehensible units, in order to avoid traditional software development issues including low cohesion and high coupling and allow for continued development. Embracing change is essential to the extensible design, in which additions will be continual. Each chunk of the system will be workable with any changes, and the idea of change through addition is the center of the whole system design. Extensible design supports frequent re-prioritization and allows functionality to be implemented in small steps upon request, which are the principles advocated by the Agile methodologies and iterative development. Extensibility imposes fewer and cleaner dependencies during development, as well as reduced coupling and more cohesive abstractions, plus well defined interfaces

And Is implementation with this method common?

I'm using ASP.NET Core 3.1 with EF Core and Azure Storage (File Storage). I am using Microsoft.Azure.Storage.File version 11.2.2 for the Azure Storage file handling.

I'm not sure exactly what this error is referencing other than a Dependency Injection (DI) issue?

Most of the articles or SO articles that I've come across referencing this error message suggest a DI, but when they inject it in Startup.cs, they have an Interface to accompany their injection. I do not.

I'm using a Razor page for this view. This code was previously written for an MVC view that I'm trying to convert for cohesion. See original post HERE. The project in MVC works without any issues. Should I just scrap trying to do this all in Razor pages and use MVC for my entire project or is there an obvious issue I'm missing??

Here is my setup:

I am trying to understand how to setup multiple python lambdas and a step function within one single serverless.yml with each python lambda having its own dependencies. All of my lambda functions collaborate in the context of a step function for a shared common goal. With this rationale, it makes sense to me to put all of the code under one serverless.yml file. As part of my MANY hours of trial and error and reading I found about the serverless-python-requirements plugin for The Serverless Framework that helps in packaging python functions that rely on OS-specific python libraries and also allow the separation of multiple requirements.txt in case different lambdas require different dependencies. So at this point my problem is that the generated package is not including the dependencies that I provide in the requirements.txt whenever each function has its own requirements.txt

These are my artifacts:

I know the question is going to sound weird, so let me start of with the issues:

I'm making a Monopoly game (for which a Monopoly class has been made that has a PlayerList member, containing players), and I had implemented an Auction class. I recently discovered that I have a lot of comparable code in the Auction class and the PlayerList class, so I put a lot of Auction-code in the BidderList class.

I have a one page template that i am trying to modify so that on clicking particular links the user goes to a new page rather than scroll to a different section. I still want to keep the scroll to a section navigation but I have call to action buttons in those sections that need to go to different pages. The website is a wordpress site
