We have setup Redis with sentinel high availability using 3 nodes. Suppose fist node is master, when we reboot first node, failover happens and second node becomes master, until this point every thing is OK. But when fist node comes back it cannot sync with master and we saw that in its config no "masterauth" is set.
Here is the error log and Generated by CONFIG REWRITE config:

I am trying to have 1 redis master with 2 redis replicas tied to a 3 Quorum Sentinel on Kubernetes. I am very new to Kubernetes.

My initial plan was to have the master running on a pod tied to 1 Kubernetes SVC and the 2 replicas running on their own pods tied to another Kubernetes SVC. Finally, the 3 Sentinel pods will be tied to their own SVC. The replicas will be tied to the master SVC (because without svc, ip will change). The sentinel will also be configured and tied to master and replica SVCs. But I'm not sure if this is feasible because when master pod crashes, how will one of the replica pods move to the master SVC and become the master? Is that possible?

The second approach I had was to wrap redis pods in a replication controller and the same for sentinel as well. However, I'm not sure how to make one of the pods master and the others replicas with a replication controller.

Would any of the two approaches work? If not, is there a better design that I can adopt? Any leads would be appreciated.

I'm trying to write a java program for currency conversion as a class assignment. My code is working almost exactly the way I would like it to. When executed, it will ask for the user to input the Japanese Yen to US Dollar exchange rate. Enter any number and that works like it should.

However, it will prompt the user next to enter the amount of US dollars they want to convert to Yen. Again, the idea is to enter any number that is > 0 because if the user enters 0 the sentinel value will force a quit and build success message. When you enter a number and click 'Enter,' it just shows a blank line and does not make the conversion like I want it to.

But if you enter a number on that next blank line then it makes the conversion! You can even type in the numbers with spaces: 10 20 50 100... it will convert all of them on separate lines.

I'm just trying to figure out how to get rid of that first black line it gives and go straight into the conversions... or some other workaround.

Here is my code:

I've created a class called zgenerator:

In my Jupyter notebook, I want to run the same KQL query against different Sentinel workspaces and compare the results as data frames. Is there an easy way to have multiple workspace connections at the same time or would I need to reconnect and query each workspace individually every time I change my KQL query?

I wrote this code to display a current value after some calculations. But the program gives wrong output when it should gave decimal 10 result it gives 13107 result and i cant find the reason why. Before this label what I did was basically getting inputs from the user and storing those values at si register.

I have few experience with React and I am trying to do Infinite scroll using GraphQL and IntersectionObserver, all work but I am getting the twice the results I request for. I guess it's from a double render, one from @apollo/client fetchMore and other from the IntersectionObserver hook but I don't quite understand it and I don't know how to fix it.

The IntersectionObserver hook:
