I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

I am writing a function majority.

The function returns True if at least two of the parameters are True.

The function returns False if at least two of the parameters are False.

The function can be written like this:

Ok, a rather specific question which requires additional explanation and context.

Context

We are POCing a "try-convert" from a bespoke language to .net core (5 currently) and blazor server. Server because it allows a try-convert scaffolding we can build security concerns round. The details of this are not important. It just explains why we have some constraints which may seem unrealistic under normal circumstances.

I am fully accepting that "no you can't" or even "no you shouldn't" is the likely outcome. We are exploring possibilities.

Question

The concept of a circuit in blazor is a really good fit for the presentation layer. We would like to store information at the scope of the circuit.

The obvious solution is to use a scoped service in the dependency injection container.

E.g. In my Startup.cs I can put

Sorry, pretty simple question:
I can't find any resource that explains the order of evaluation of the ENV variable in Laravel... Usually in Spring Boot if I define a variable in the docker-compose I know for a fact that it overrides the application.properties value.. is the same in Laravel?

E.g.:
.env

Based on the guide Implementing PCA in Python, by Sebastian Raschka I am building the PCA algorithm from scratch for my research purpose. The class definition is:

I followed this tutorial to create a rails plugin.

Section 3 explains how to add a method to string that is available anywhere in a Rails application. Now for my case, I want to be able to access rails methods in the plugin itself.

For example in lib/plugin/my_plugin/my_plugin.rb I want to use:

I'm using SignalR on ASP.NET Core 5 web server for Android device management. I can send messages from device (D2C), and receive messages with String parameters (C2D). But I can't receive messages with custom object parameters, the handler receives all object members as null. I develop an WPF client and it receives this object well.

I'm following ASP.NET Core SignalR Java client documentation. It explains how to use custom objects in Passing Class information in Java section.

In build.gradle file:

The turbo handbook explains target: '_top' here and here.

But I still don't understand what's the difference between these two forms:

This explains the "Bridge" pattern I'm referring to: https://refactoring.guru/design-patterns/bridge

Here's a scenario from the post above:

Say you have a geometric Shape class with a pair of subclasses: Circle and Square. You want to extend this class hierarchy to incorporate colors, so you plan to create Red and Blue shape subclasses. However, since you already have two subclasses, you’ll need to create four class combinations such as BlueCircle and RedSquare.

The problem this scenario presents:

Adding new shape types and colors to the hierarchy will grow it exponentially. For example, to add a triangle shape you’d need to introduce two subclasses, one for each color. And after that, adding a new color would require creating three subclasses, one for each shape type. The further we go, the worse it becomes.

To avoid this problem, we implement the Bridge pattern like so:

Extract the color-related code into its own class with two subclasses: Red and Blue. The Shape class then gets a reference field pointing to one of the color objects. Now the shape can delegate any color-related work to the linked color object. That reference will act as a bridge between the Shape and Color classes. From now on, adding new colors won’t require changing the shape hierarchy, and vice versa.

I understand the how and why of this implementation.

But what if we need a third hierarchy, e.g. BorderStyle (where a border style can be Straight, Wavy, or ZigZag?)

I guess we could implement a second Implementor class for BorderStyle and pass it into a Shape constructor like so:
