jenga | app calculates how many packages

So this code I found below doesn't work I get to the authenticate screen then when t redirects me it just says Not logged in, Login in again. Does anyone know what I have to do to fix this? I am not very good at OATH2 and would like someone to walk me through.

I used the code from this gist.

I made a socket connection between a client and server. I set it up so it makes a request for data, but it doesn't receive the data. It throws Traceback (most recent call last): File "C:\Users\jenga\Desktop\Jacobs_Python\net\server\server.py", line 38, in s1.connect((host1, port1)) ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it, but it sends a response. How can I set it up to receive the message? By the way, it makes a request to the server to read a file.

Server.py:

I have hundreds of thousands of mostly jumbled lines which contains emails and other data. Everything which appears before an email address is essentially useless, and can be purged/deleted/removed/sliced - unsure of correct terminology, sorry.

I tend to use Cygwin for these types of things, but have been struggling a lot. This is the email regex I generally tend to use:

Am working on a Laravel project whereby when the user hits submit button on a form (which has hidden input values), I redirect the data to the server-side logic (build with PHP), perform some computation and later redirect to the frontend (as a response inside AJAX success) which works fine, next, I populate the response to some of the inputs of the form and finally call submit method (via jquery).

When I open network tab in the browser,, I see that the data keeps being posted alot of times but I want it to be posted only once without refreshing. Please assist?

Form

I have got a file input field on a form. I am changing the text of the button dynamically depending on whether the input field has a file uploaded or not. It works fine except that I have to refresh the page so that the text changes. I want the text to toggle instantly depending on the status of the input..

Input field

Am working on a form whereby after the user hits submit button, am submitting the data to the backend using AJAX whereby I fetch some more values and redirect back to the frontend using AJAX. I want to fetch the values via Jquery and populate them in the form. Next populate the values back to the form since I dont want to submit the form via AJAX since it si supposed to open an iframe.

Form Layout

I am trying to create a Jenga game to start with learning how to use SceneKit.

I have set all the physics in my scenes, as so (Left image - block.scn | Right image - Scene.scn with image of the scene):

The blocks on the right don't have the physics directly set to them, as they are reference nodes therefore adding physics will make it no longer work properly. (The three blocks have just been moved to the side to allow the structure to fall.)

When I run the app, the blocks fall and act as expected. However, the problem occurs when I attempt to remove a node. Here is what it looks like, and here is a link to the video to see what is happening:

During the video, I removed a block as the physics was happening and other blocks fell as expected, but after that nothing happened after removing more blocks.

I remove the blocks using node.removeFromParentNode():

I have array which i got as a result from nodeJS code
