Freestyle pipeline allows more flexibility in defining build steps compared to normal pipeline. Build success can be checked by examining the build status or logs.

• Freestyle pipeline allows users to define build steps manually, while normal pipeline follows a predefined structure.

• In freestyle pipeline, build steps can be configured using GUI, whereas normal pipeline uses a script-like syntax.

• To check if a build is successful, you can look at the build status (e.g. success/fail...read more

Use remote backend in Terraform to manage state file in a common place.

• Use remote backend in Terraform to store state file in a shared location like AWS S3 bucket or Azure Blob Storage.

• Configure Terraform to use the remote backend by specifying the backend configuration in the Terraform configuration file.

• Ensure proper access control and permissions are set up for the shared storage to prevent unauthorized access.

• Use locking mechanisms provided by the remote backend to preven...read more

Divide 1000 servers into 100 groups to check if streams are strictly increasing in parallel

• Divide the 1000 servers into 100 groups of 10 servers each

• Assign each group of servers to a separate processing unit for parallel checking

• Check if the stream on each server within the group is strictly increasing

• Combine the results from all groups to determine if all streams are strictly increasing

Check if array can be made strictly increasing by modifying at most 2 elements.

• Iterate through the array and check if each element is greater than the previous one.

• If there are more than 2 elements that need to be modified, return false.

• Examples: ['1', '2', '3'] -> true, ['1', '3', '2', '4'] -> true, ['1', '1', '2', '3'] -> false

Print values of nested json element in array format

• Access the nested json element using dot notation

• Iterate through the array to print each value

• Current version of Linux is 5.14.6

• Running processes in Linux can be viewed using commands like ps, top, and htop

Calculate total run time of overlapping time ranges

• Sort the time ranges by start time

• Iterate through the sorted time ranges and merge overlapping ranges

• Calculate the total run time by summing up the merged ranges

System calls when a process is created

• fork()

• exec()

• clone()

I have experience working with AWS, GCP, and Azure cloud providers.

• Managed infrastructure on AWS EC2 instances

• Utilized GCP services like Compute Engine and Cloud Storage

• Deployed applications on Azure Virtual Machines

Encryption is reversible, while hashing is irreversible.

• Encryption is a process of converting data into a code to prevent unauthorized access.

• Hashing is a process of converting data into a fixed-length string of characters.

• Encryption uses algorithms like AES, RSA, while hashing uses algorithms like MD5, SHA-256.

• Encrypted data can be decrypted back to its original form, while hashed data cannot be reversed.

Design a scalable logging system for 1000 hosts.

• Use a centralized logging server to collect logs from all hosts.

• Implement log rotation to manage disk space efficiently.

• Consider using a distributed logging system like Elasticsearch, Logstash, and Kibana (ELK stack).
