I know there are some other questions (with answers) to this topic. But no of these was helpful for me.

I have a postfix server (postfix 3.4.14 on debian 10) with following configuration (only the interesting section):

I'm creating 2 pages (Summary and Cycles pages) using react.js.

On the Summary page, there is a column named CN that every item links to the Cycles page.

Summary page has a path /route/summary/location=abc and Cycles page has a path /route/cycle/location=abc/deviceId=4410

For example, if I click the value from CN column in the first row of the table inside the Summary page, I will be redirected to the Cycles page with the path /route/cycle/location=abc/deviceId=4410.

In the Summary page, I use https://github.com/react-bootstrap-table/react-bootstrap-table2 for the table component and I use a columnRenderer function inside columns.js to render a custom item inside the table like this one:

How can I put the pathname (example "abc") to a Link component inside cnColumnRenderer function in columns.js?

Summary page with the path: /route/summary/location=abc

Cycles page with the path: /route/cycle/location=abc/deviceId=4410

Error because of invalid hook call while rendering the Summary page

table code inside Summary page (inside Summary.js):

hint: focus on columns variable from './columns' and its implementation

I am using an if else statement to convert the values in column X into bins in a new column Y. Code:

When the Auto Scaling Group creates a new instances, the code from CodeDeploy is not downloaded and installed on a newly created EC2 instance.

I've followed the documentation here: https://docs.amazonaws.cn/en_us/codedeploy/latest/userguide/tutorials-auto-scaling-group-create-auto-scaling-group.html

And the last steps says

Install the CodeDeploy agent by following the steps in Install the CodeDeploy agent and using the Name=CodeDeployDemo instance tags.

My "user" script run on the new instance from the ASG (Auto Scaling Group) correctly installs and run the CodeDeploy agent (connecting to SSh to the machine and running a service codedeploy-agent status shows its running), but from there, I don't know how to tell CodeDeploy to deploy the code to that instance. (Or to run CodePipeline for that instance?)

Could you help me point into the right direction on what to do here? I'm happy to provide any details that are lacking here if you need any!

Thank you!

I have the following problem and I am wondering if there is a faster and cleaner implementation of the removeLastChar() function. Specifically, if one can already remove the last vowel without having to find the corresponding index first.

PROBLEM

Write a function that removes the last vowel in each word in a sentence.

Examples:

removeLastVowel("Those who dare to fail miserably can achieve greatly.")

"Thos wh dar t fal miserbly cn achiev gretly."

removeLastVowel("Love is a serious mental disease.")

"Lov s serios mentl diseas"

removeLastVowel("Get busy living or get busy dying.")

"Gt bsy livng r gt bsy dyng"

Notes: Vowels are: a, e, i, o, u (both upper and lowercase).

MY SOLUTION

A PSEUDOCODE

1. Decompose the sentence
2. For each word find the index of the last vowel
3. Then remove it and make the new "word"
4. Concatenate all the words

CODE

I'm creating an int (32 bit) vector with 1024 * 1024 * 1024 elements like so:

The regex expression below is for finding valid Amazon Cognito IdentityPool IDs with a test file but using the same expression with grep finds no valid matches yet the regex matches the test strings on https://regextester.com Regex expression: (us(-gov)?|ap|ca|cn|eu|sa)-(central|(north|south)?(east|west)?)-\d:[0-9a-f-]+ or even simplified like [\w-]+:[0-9a-f-]+. Both fail for test strings like below yet are matched on Regextester.

I have to calculate the value of S, which has the formula as: S = (25400/CN) − 254

the CN value which I have to choose will depend on the amc_active condition viz 1, 2 and 3. if amc_active condition at 'index 0 or 1st row' is 1 then I have to choose the CN value from column cn1 i.e 47

and if the amc_active is 3, then I have to choose CN value as 95 from cn3 column in the 4th row and so on..

When I wanted to add a function to my button component, I found a bug in my approach, which is that I have to click the button once more to achieve the desired effect. In xml I setup the button like this:
