QUESTION
I am currently busy with a user list challenge and this is the challenge:
-add 3 new users to the database (get them via user input, not hard coding) -remove a user from the database by their index. (user input, no hard coding) -concatenate/merge all usernames in the database into one String and display it appropriately in -the DOM -sort the usernames in the database alphabetically and log it out to the console
This is my code:
...ANSWER
Answered 2022-Mar-22 at 14:30I've gone ahead and corrected some of the errors in your program but there are still some in there in some of the functionality you have written that you need to correct. This is just to give you a working skeleton for your application.
Key changes:
- You need to parse the input as
number
otherwise your switch won't work as you expect it to - You need to switch on the parsed value of
menu
not onuserlist
asuserlist
is an array and you are trying to compare that with anumber
in yourswitch
statement - I've added an infinite loop to your application which means a user will always go back to the menu after some option has been selected and can select the next thing he/ she wants to do. To be able to exit this loop I have added an Exit options which will end the application.
You may run the application now. Adding users as well as displaying users should work.

is a dataframe. If you do if 'Black' in file
it will only search the column names (which are ['Name', 'Colour', 'ID']
).
You need to be more specific about where you want to search (i.e. which column to search).
To find 'black'
in the colour column use:

I am looking for a organization chart plugin for vue 3 and I have found only this one
https://github.com/megafetis/vue3-blocks-tree
The issue that I have is when changing the ref treeData
variable the chart is not loading the new structure.
I want to dynamic load the chart. When fetch the data the chart to loads the new data and display it.
Here is the codesandbox example:
https://codesandbox.io/s/flamboyant-gwen-o8vp9?file=/src/App.vue
When press the Add ... the treeData
reference variable should load the new data and the chart to display it ... but it doesn't.
Any ideas ?
Should I reload the component on every fetch ?

reactive.
Replace ref
to reactive
for treeDate

Change parts of treeData
on onAddData
instead replacing all object.

QUESTION
Kafka machines are installed as part of hortonworks packages , kafka
version is 0.1X
We run the deeg_data
applications, consuming data from kafka
topics
On last days we saw that our application – deeg_data
are failed and we start to find the root cause
On kafka
cluster we see the following behavior
ANSWER
Answered 2021-Dec-23 at 19:39The rebalance in Kafka is a protocol and is used by various components (Kafka connect, Kafka streams, Schema registry etc.) for various purposes.
In the most simplest form, a rebalance is triggered whenever there is any change in the metadata.
Now, the word metadata can have many meanings - for example:
- In the case of a topic, it's metadata could be the topic partitions and/or replicas and where (which broker) they are stored
- In the case of a consumer group, it could be the number of consumers that are a part of the group and the partitions they are consuming the messages from etc.
The above examples are by no means exhaustive i.e. there is more metadata for topics and consumer groups but I wouldn't go into more details here.
So, if there is any change in:
- The number of partitions or replicas of a topic such as addition, removal or unavailability
- The number of consumers in a consumer group such as addition or removal
- Other similar changes...
A rebalance will be triggered. In the case of consumer group rebalancing, consumer applications need to be robust enough to cater for such scenarios.
So rebalances are a feature. However, in your case it appears that it is happening very frequently so you may need to investigate the logs on your client application and the cluster.
Following are a couple of references that might help:
- Rebalance protocol - A very good article on medium on this subject
- Consumer rebalancing - Another post on SO focusing on consumer rebalancing

QUESTION
I'm designing an SSRS badge report for Avery 5392 badge stock (6 per page) that will also print each wearer's record ID on the back of their badge.
I've set up RowNumber & RowMod columns in my SELECT statement so that I can filter into my design elements only 3 rows of data per column and control which rows go on the left or right-side report elements, respectively. I've also set up PageNumber as a possible grouping option for page breaks.
Please consider this dummy table as a proxy for the data I'm actually using:
...ANSWER
Answered 2021-Sep-14 at 21:03I've taken your sample data and reworked the query to give the data I would use if I need to do this. It may not suit your setup exactly but it should be close enough to revise.
I basically output page numbers and row and column numbers from the dataset query that we can then use in a Matrix control.
Here's the modified query..
