Visitor | The Hoa\Visitor library | SQL Database library

I'm working on a hobby project. The project is basically an integrable live support service. To describe my questions easily, I will call my service service.com and call the website that uses my service website.com. I'm thinking on implementing session management to restore disconnected visitors chat. To do that I'm planning to use cookie based session management. If owner of the website.com wants to use my service I will provide them a JavaScript file which will inject some HTML on the body, style tags on head and implement interaction. All the website.com's have to do will be importing that JS file and calling a function defined by that JS file. To set 3rd party cookies on that website.com from my service.com I will use this request/response. When website.com requests my JS file from service.com, my service will respond the request with the JS file along with a cookie to manage visitor's sessions. This way service.com will set 3rd party on website.com's visitors.

1st Question: Could this stage of setting cookie on website.com's visitor done on the front-end with that requested JS file or locally (from the website.com's web server) requested JS file? Would that still be a 3rd party cookie since it would be set on the front-end of the website.com?

2nd Questios: My other question is about cookie consents. Can a website that sets 3rd party cookies (e.g service.com) on some other website (e.g website.com) ask to allow their cookies on that website.com? In other words, can I ask website.com's visitors to allow only 3rd party cookies that are set by service.com with the JS file I serve/give to website.com? Would that be legal?

3rd Question: How do cookie consent banners work behind the scenes? What happens when you accept/deny all of the 3rd party cookies used on a website? Or what happens when you filter and accepy only a few of them? How does the process of allowing/disallowing work? Is there some kind of JavaScript that is triggered when you click that "Accept" button or "Decline" button? You can provide me any resources on this topic.

Thanks!

In JOINT STRIKE FIGHTER AIR VEHICLE C++ CODING STANDARDS Bjarne states, that:

Down casting (casting from base to derived class) shall only be allowed through one of the following mechanism:

1. Virtual functions that act like dynamic casts (most likely useful in relatively simple cases)
2. Use of the visitor (or similar) pattern (most likely useful in complicated cases)

I can't wrap my head around first proposition. Googling it presented no examples, nor explanation.

How can virtual function act like a dynamic cast?

I updated from ruby 2.7.1 to 3.1.1, then removed Gemfile.lock and ran bundle update (it's on a dev branch, so I can throw it away if this is a bad idea, I just wanted to see if it would work).

bundle update succeeds, but when I start the server:

I know this is well trodden territory but I have a specific question... I promise.

Having spent very little time in the statically typed, object oriented world, I recently came across this design pattern while reading Crafting Interpreters. While I understand this pattern allows for extensible behavior (methods) on a set of well defined existing types (classes), I don't quite get the characterization of it as a solution to the double dispatch problem, at least not without some additional assumptions. I see it more as making a tradeoff to the expression problem, where you trade closed types for open methods.

In most of the examples I've seen, you end up with something like this (shamelessly stolen from the awesome Clojure Design Patterns)

And how to fix the code?

Here is the code: https://godbolt.org/z/vcP6WKvG5

I have the following code:

Related to, but not the same question as How does std::visit work with std::variant?

Implementing std::visit for a single variant conceptually looks like this (in C++ pseudocode):

The main problem is simple, really. Given a base (more abstract) class and multiple derived ones that need to interact with each other, how do you go about doing it?

To give a more concrete example, here is an implementation with hitboxes for a 2d videogame:

I had a private repo for 6 months that I worked on. Today I finally made it public after submitting a paper. Is it possible to make the activity (those green square) visible? I tried clicking on contribution setting and got the message Visitors will now see your public and anonymized private contributions, but the activity still doesn't show.

Update 1:

I noticed that only changes I did on GitHub (the website rather than pushing code from my machine) were recorded. That is, only the readme file shows as I often updated it on the website.

Update 2:

I ran git --no-pager log -s --format="%ae" to see which emails were used for the commits and got the following: Some emails are the primary email under GitHub, some are of the form 43555163+Penguin@users.noreply.github.com, some are Penguin@Penguin-MacBook-Pro.local, some are Penguin@econ2-204-32-dhcp.int.university_name.edu.

Also, as I mentioned in one of the comments below, if I go to my repo and specifically look at commits I can see something like: Penguin authored and Penguin committed on May 27 1 parent 1d71ac3 commit cb95c2870de67383ee653849b4c7b40a062f5fd3. But this does not show on my activity.

Lastly, some comments mentioned creating a new repo on GitHub and pushing my previous commits (after filtering the emails somehow which I didn't quite understand). However, I already have several Stargazers on this repo and would like to keep them. By making a new repo I believe these will disappear.

Update 3:

I used git filter-repo to change all the emails to my primary email and now all my previous commits emails appear to be my primary email when I call git --no-pager log -s --format="%ae". However, I still don't see the activity showing. For example, if I go to my repo I can see that one of the commits says Penguin authored and Penguin committed on Apr 8, but this doesn't show in the activity.
