plethora | Mixture of app things

I am willing to parse https://2gis.kz , and I encountered the problem that I am getting error while using .text or any methods used to extract text from a class

I am typing the search query such as "fitness"

My window variable is

I'm recreating a simple weather app with react and am having a lot of trouble creating a very simple API call. I've tried a plethora of methods on here, youtube, etc and continuously get errors. The current code I have is:

I want to set up a EKS cluster, enabling other IAM users to connect and tinker with the cluster. To do so, AWS recommends patching a config map, which I did. Now I want to enable the same “feature” using terraform.

I use terraforms EKS provider and read in the documentation in section "Due to the plethora of tooling a..." that basically authentication is up to myself.

Now I use the Terraform Kubernetes provider to update this config map:

I am using mod_wsgi to run my Django app. As there are a plethora of options to define when the server run command is fired, I was trying to create some kind of python script to pass the options and their pre-set values.

For example:

I am using CSV dataset with 1 feature column (string) and 97 label columns (multi-label classification) with 1 or 0 for every row. Data:

I have just switched one of my multiselects to select2 as my previous checkbox multiselect was incompatible with my new page template CSS and looked very out of place.

What is meant to happen is in the first multiselect (now select2), users can select their plethora of options and a second multiselect below would populate with the relevant options that are tied to the first already selected and the field read only. This worked fine previously but is no longer doing so.

This is the code I'm using. The options for hazards in the select2 are pulled from a DB which is working as intended.

As the title suggests I'm trying to use in the same application two different socket.io servers, one with socket.ioV4 and the other with socket.ioV2, the servers go up but I fail to get the sockets to connect.

A bit of context: the reason I'm trying to do this is because two clients need to exchange data using the Node.js application as a bridge, and each of them requires a different version of the socket.io package (as mentioned, V4 vs V2).

What I managed to do: I installed the V4 version as usual and the V2 version using an alias

I need to create AWS CentOS 7 instance images for a customer, and need it to automatically send the ip and instance id to our AWS server every time the instance boots. For example, this is the very basic test version of the script I need to run:

I've heard of people making their own software products and selling it. Sadly, I don't know anybody of such calibre personally. I want to know where could I learn such software design principles and architectures (not for a personal project like taught in the plethora of YouTube videos that exist, but real world application with concurrent user handling and scalability). It would be helpful if someone who knows these things could point me to the right resources. Thank you. [Please only mention resources that you are personally sure of.]
