I have a scatter plot as you can see below.

I want to change color points for each year which is stored in a list, here is a reproducible code :

The code discussed here is written in C# and executed with .netcore 3.1

I have the following piece of code, which starts a workload in the background without awaiting for it to complete (fire and forget):

So I have been writing a function to generate a key as a tuple using randomly generated prime numbers, and when I try to run the code it generates the error(s),

I need to use a constructor to initialize an array of class objects, but I can't figure out the syntax to make it work. I need to include one String and five ints. Here are some neccessary details from my code.

I have an assignment to show the roots of a quadratic equation, which usually are imaginary numbers. I am wondering how can I produce two roots and what to do in the case of an imaginary root. Here is what I have done so far. (first time using this site so I am not too familiar with etiquette and the tools yet so forgive me if my post is weird)

(EDIT: Sorry. Forgot to mention. Postgresql 13, PostGIS: 3.1 USE_GEOS=1 USE_PROJ=1 USE_STATS=1. Sorry about that).

The following 2 queries, in my opinion, should return "true" in both cases. The point is clearly within the polygon (square). Displaying both certainly indicates so. I am starting to wonder what fondamental thing I am missing here.

To be honest, I have been circling around this issue for years, as I am never able to find something "final" to understand what is happening. In this case, the point is somewhat near the edge of the polygon, but from time to time I had the same issues with points that were well within the polygon.

The only difference between the 2 queries is that one uses geometry the other uses geography. As you can see, we use 0.0 for the distance value. This is like an intersects.

OH, and by the way, using intersects yields the same results. I am very confused about this.

this is my first post and I am very new to python, so excuse me in advance if my questions/etiquette are not polished enough. This might be a very trivial question.

Here is the thing: I am trying to develop an app that will periodically check a calendar via the Google Calendar API for new events, then produce a QR code including the calendar ID and event ID.

Since I am new to python, i searched for something that would maybe make things smoother and found gcsa: https://github.com/kuzmoyev/google-calendar-simple-api ,which is very nice and convenient.

The issue I am having is that using the gcsa, the default way of listing events in a calendar returns only the event timing and name:

I am working on an ASP.Net application using VB.Net with Visual Studio 2019 version 16.8.4. While investigating an issue with breakpoints, I noticed that what Build Solution is creating under Temporary ASP.Net Files\root folder is not what is being created under the Temporary ASP.Net Files\vs folder when I debug. Files are missing. I deleted ALL files and folders under Temporary ASP.Net Files before Building and Debugging for this post.

The files under root are

Am new to python and stackoverflow so I don't know all the etiquette of the site.

So, I have created a random field of vectors with length 1, and I am trying to write code that will adjust each value to the average of its 4 neighbours. I have written this code:

s= size of field, l = amount of times to loop
