incase | Pipe-Friendly Vector Replacement with Case Statements | Data Visualization library

I have an image (QR image) that i have to display it, and keep refreshing it every time. I tried many solutions but none worked, this is my code:

readinessProbe: Indicates whether the container is ready to respond to requests. If the readiness probe fails, the endpoints controller removes the Pod's IP address from the endpoints of all Services that match the Pod. The default state of readiness before the initial delay is Failure. If a Container does not provide a readiness probe, the default state is Success

If the readiness probe fails (and the Pod's IP address is removed from end point), what happens next? Will the Pod's readiness probe conditions be checked again? Will it check again after initial delay? Is there any chance the Pod's IP address is added to the end point again (if the Pod self healed after readiness probe fails)? Will that Pod receive traffic again incase if it's healed?

I am trying to add a phone number mask using jquery. I am having an issue with the hidden phone number fields that get added after user asks for more phone number fields.

I was wondering if someone here could help better explain For loops than my textbooks.

I'm writing a program in Python where the program askes a user if they're already an existing user. If they are an existing user, the program starts. If they're not an existing user, they're prompted to create a username and password.

I was wondering if someone could help explain how I could use a For Loop to loop the if statement incase a user enters some unexpected input like A or a number.

Thanks

Here's a code snippet of an if statement I have where it goes:

I face the problem that I have a list of keys inside my firebase database and I want to retrieve one random key out of it, without downloading all keys and selecting one in my own app. Downloading all keys with for example .once() is a big no go, especialy because I may up end with 10.000+ keys in the future and I dont want my firebase bills to explode, Im still a student with no budget at all.

I already researched this topic and found following answer for my question.

The problem with this is, that I can not use limitToFirst() and also limitToLast() in the same query, else I get following error:

[Unhandled promise rejection: Error: Query.limitToLast: Limit was already set (by another call to limit, limitToFirst, or limitToLast).]

Also other people face the same problem like me and I generaly see that this question always gets much views but rather poor answers which are, like apperently in the case I mentioned earlier outdated, or just not for usage in Javascript and React-Native.

Additional informations: I have a counter for my keys so I know at every time how many keys are stored inside my database. Following picture shows my database entirely:

This is the part of my code which shows the mentioned error:

I am working with existing data and have records which contain an array double[23] and double[46]. The values in the array can be the same across multiple records. I would like to generate an id (perhaps an int) to uniquely identify the values in each array.

There are places in the application where I need to group records based on the values in the array being identical. While there are ways to query for this, I was hoping for a single int field (or something similar) to group on. This would really help simplify queries and especially help with report tools where grouping on a smaller single field would help immensely.

I thought of generating a hash code, but I understand these are not guaranteed to be the same for each double[] with matching values. I had tried implementing
