System Design: Forward Retry Mechanism In Distributed Architecture
A Forward Retry is a mechanism where a failed operation to an external service(s) is automatically attempted again after a certain delay. The primary purpose of this design is to handle transient network failure, temporary outages thereby improving the reliability of the system. I recently faced a similar situation at work where I had to…

Setup Frontend Project Without Needing Backend Using Local Storage (Dependency Injection)
Frontend applications have evolved with frameworks like React, Angular, and Vue, allowing for complex logic and seamless user experiences. The entire DOM is now generated using JavaScript, giving developers more control. This article discusses a design pattern that decouples frontend development from the backend, allowing frontend code to run without relying on backend readiness or API responses.

A Brief Discussion On Frontend and Micro-frontends
Monoliths are blocks of code that are used in software development. They are like large monuments which are the first choice when starting a project because they are fast to develop and release new features with. However, over time, these monoliths can become barriers to development, so they can be broken down into smaller pieces called micro-frontends. This helps with scaling the codebase, making it easier to manage and maintain, and allowing teams to collaborate more effectively.

A Well Functioning Team – Feedback Culture
If you are following the form based feedback practices in your team, I would encourage you to move away from it. Here’s the reason why.
Replication – How Is It Done In Distributed Systems?
Replication simply means keeping a copy of the same data on multiple machines connected via a network. These machines could be present in different parts of the world and not necessarily in the same perimeter.

Freedom From Redundancy Is A Trade-off
Code redundancy is a good thing as long as you know the trade-off. Abstracting out everything just for the sake of reducing code duplicity is stupid.
Why Do Developers Write Code That Slows Them Down
When I started asking this question myself, I started getting various reasons for the not-so-good code. I made a note of these reasons. And today I’ll elaborate on each one of those. I guess you will relate to these and feel free to share your views on the same.

Code Review Best Practices For Software Engineers
Raising a good PR is as important as writing good code. If you have written an excellent code but it is all over the place then it would take much more time to go through. Instead, write good and **precise** code, raise a PR. Write good code again, raise a PR. That’s the way to move forward faster and securely.

Generate Pseudo Random Numbers With Linear Feedback Shift Register (LFSR)
The world of random is very intriguing. It made me think hard enough about randomness. I think there’s nothing like random if given the state of the system and the rules it follows. Even the Geiger counter. If we somehow know what caused the radiation and the initial state which led to it, then maybe with super quantum computers we might be able to predict the count of electrons in the next interval 😀
