Background It’s an interesting challenge to learn about the core concepts of NodeJS. I got this challenge from one of my colleague and engaged in the solution for about a couple of days. But I didn’t solve it with the shared constraints. Challenge: Cluster locking Playground Idea 1 concept The plan was to store the output in a common object to share data from worker to worker. But it didn’t work as in Node Cluster is running in different process and no data can be shared worker to worker directly in Node Cluster....

Concurrent execution and multiprocessing using Python Python defaults to a single-threaded execution due to the Global Interpreter Lock (GIL). Despite the pros and cons associated with the GIL, Python now supports the implementation of multiple interpreters concurrently. This playground implements the multithreading concept using a Python program to maximize concurrency, leveraging the concurrent.futures module. A prime-checking program has been developed, omitting optimized algorithms like the Sieve of Eratosthenes. When executed in the typical single-threaded fashion, the program takes 83 seconds to count the number of primes from 1 to 10 million....

NextJS app deployment using Gitlab CI Streamline the deployment of your Next.js application effortlessly with GitLab CI automation. Enhance efficiency and reduce deployment hassles with a seamless integration approach. Let’s dive in. TL;DR Issue: In the NextJS deployment on production, downtime occurs due to server building. Pulling the updated code from the Git repository and running next build on the production server leads to the unavailability of the application. Resolution: To mitigate this issue, a proposed solution involves building the application in a separate environment and storing the successful build in a Docker registry....

Automate API Testing using Postman & Newman Introduction Postman is one of the most used tools for a developer. Most of the time, we develop APIs and test those individually. But in some scenarios, we have to test APIs in batches if they are dependent on each other. By utilizing the knowledge, we can do our tasks easier as well as minimize repeating tasks. Through this, our dev testing time can be reduced....

Load Balancing Playground with Nginx and Docker Introduction: Assuming you have already heard the term ‘Load Balancing’. If not, then refer you to learn a very basic about the technique from this load balancing wiki. The concept of the task is to make multiple App servers and a Load balancer to balance the traffic. In this write-up, I am sharing my experience to start learning load balancing. Background: Different VMs can be created for the app servers and the load balancer in the virtual machine....
