wormhole | A wormhole simulation | Graphics library

I am unable to get the links from this website called: https://riwayat-file-vaksinasi-dki-jakarta-jakartagis.hub.arcgis.com/

I use the following code:

WHAT I'M DOING

I'm rendering circular points with varying vertex colors using a fragment shader. I in essence want the points to act as more performant spheres that are antialiased when zoomed all the way in.

PROBLEM

It works in one direction (see left photo), but the other direction has white corners (see right photo). How do I get rid of the white corners?

WHAT I TRIED

• If the points were all the same color, I could turn off depthTest and it would just work. However, the points must be varying colors. Turning off the depthTest with varying colors makes it look like a wormhole.
• I tried alphaTest to no avail. I did get alphaTest to work with textures instead of a custom fragment shader (png of a circle on transparent background), but it looked blurry when zoomed in sufficiently.
• I did notice that the colors of the corners was equivalent to whatever I passed into renderer.setClearColor.
• I've played around with blending options, but I'm not familiar enough with blending yet to understand what I'm doing.

CODE

I want to display the youtube thumbnails list as a banner list in my app in Page view. I parsed the Json data using a video on youtube but I am getting an exception "Unhandled Exception: type 'double' is not a subtype of type 'int'"

I shall put down everything I have done and put a small explanation

Im new to coding, and pretty confused by the concept of class 's and how to use them. Im making a zork game as a practice exercise and have the following as part of my code:

I am new to react hooks and fairly new to react. I am trying to generate a dropdown list that pulls values from my server. I am having trouble removing the duplicates from the list. This code probably needs a lot of re working but any help would be appreciated. I include the songform.js below and I will add what my mongodb information looks like.

Stuying Springboot, I got myself into an infinite wormhole of errors. Here is the last one: No qualifying bean of type 'ca.company.hello.A' available

However, what puzzles me is that I do define the bean:

I have installed tinymce in my EmberJS application. When I run npm start or even npm run build, I get an error like so:

I am learning QT and QT Creator to have experience in working with it. Using Arch Linux with the latest QT libraries.

On a button click function, I am trying to do the following:
