drain | To run at the command line

I am reading through the Rust book and doing the optinal exercise along the way. I've finished the chapter 8 (Common Collections) and am trying the last exercise. The exercise instructions are:

Using a hash map and vectors, create a text interface to allow a user to add employee names to a department in a company. For example, “Add Sally to Engineering” or “Add Amir to Sales.” Then let the user retrieve a list of all people in a department or all people in the company by department, sorted alphabetically.

What I want my program to do is firstly ask the user if they want to add a new employee, if no, the program ends else it allows them to continously add an employee until the user declines to add any more.

I've chosen to simply start with the initial user prompt asking if they want to add a new employee. I start with an empty String for the user input, once the user enters their response there is a while loop that repeats until the user enters a valid response ([Y/n]). Since the condition for the while loop is when the response is not equal to "y" or "n" I expected correct responses to skip the while loop but instead the while loop is always entered and never exited no matter what. Since I'm new to Rust I'm not sure if there some obvious or idiosyncratic reason for this behaviour. I'll also add that I remove whitespace (incl. \n) from the response and make the response lowercase in the while loop condition, all of which can be seen in my code below.

I have two sequential API calls so I decided to use RxJava flatmap to accomplish it as below code,

I am currently testing the scaling of my application and I ran into something I did not expect.

The application is running on a 5 node cluster, it has multiple services/actortypes and is using a shared process model. For some component it uses actor events as a best effort pubsub system (There are fallbacks in place so if a notification is dropped there is no issue). The problem arises when the number of actors grows (aka subscription topics). The actorservice is partitioned to 100 partitions at the moment. The number of topics at that point is around 160.000 where each topic is subscribed 1-5 times (nodes where it is needed) with an average of 2.5 subscriptions (Roughly 400k subscriptions).

At that point communications in the cluster start breaking down, new subscriptions are not created, unsubscribes are timing out. But it is also affecting other services, internal calls to a diagnostics service are timing out (asking each of the 5 replicas), this is probably due to the resolving of partitions/replica endpoints as the outside calls to the webpage are fine (these endpoints use the same technology/codestack).

The eventviewer is full with warnings and errors like:

I have a partially reactive flow that reads from SQS, performs some logic, saves to DB (R2DBC). The flow runs on a reactive channel which is the inbound channel for SqsMessageDrivenChannelAdapter.

The Issue:

Exceptions thrown in the handle method (.handle((payload, header) -> validator.validate((Dto) payload)) ) do not reach the flowErrorChannel. The errorProcessingFlow is not triggered, I need the errorProcessingFlow to log and throw the exception to SimpleMessageListenerContainer.

The same works as expected if I change the objectChannel and flowErrorChannel from flux to direct, but not with Flux channels. With flux channels the exception is not even propagated to SimpleMessageListenerContainer since it does not trigger a redrive as per SQS queue config, the exception from the handle is only logged.

Here is the exception and the flow config:

I have a problem connecting to the ipmi server via paramiko in this code:

For Kafka cluster hosted in Confluent Cloud, there is an Audit Log cluster that gets created. It seems to be possible to hook a Sink connector to this cluster and drain the events out from "confluent-audit-log-events" topic.

However, I am running into the below error when I run the connector to do the same.

I have a stream which feeds a list of items typed as 'Client'. I have too a search bar which the user writes some name and the list should filter the results as searched and when Click at other button named 'clear' it should reset the list to default. So, I have wrote these methods:

The clones spawn with an EnemyHealth script where their health parameters are set. Within in this script is a function called TakeDamage(). My only guess is that I'm not explicitly defining which enemy needs to have it's health drained within TakeDamage() but I'm having some trouble wrapping my head around that because each clone has its own health and TakeDamage() is called from my PlayerAttack script when the weapon collides with the enemy, so I was assuming it would only happen to the colliding enemy. But I guess I need a defined way for TakeDamage() to only affect the enemy that's involved with the collision.

I'm self taught so I apologize if this is simple or a poor question, I've searched all over the place for several days now so I hope someone can help!

I have a class strings:
