Building an Idempotent Payment System with Spring Boot & React

Payment systems are at the core of modern web applications, but they come with a tricky problem: duplicate transactions. Whether it’s a user accidentally clicking “Pay” twice or a network retry causing multiple API calls, duplicate charges can quickly erode trust and create operational headaches. In this blog, I’ll walk you through a full-stack idempotency … Continue reading Building an Idempotent Payment System with Spring Boot & React

Boosting Efficiency in Microservices with Bazel – Part 1

Modern software development often relies on large-scale microservices architectures. However, ensuring efficiency and consistency in building and testing these systems can be challenging. Key issues include: Slow Build Times: Building large-scale applications with multiple dependencies often leads to extended build durations, negatively impacting developer productivity. Inconsistent Build Environments: Variations in developer environments and CI/CD pipelines … Continue reading Boosting Efficiency in Microservices with Bazel – Part 1

Efficient and Reliable Multi-Architecture Docker Image Building with BuildX

Building and distributing single-architecture Docker images efficiently and reliably across diverse computing environments presents a significant challenge. Additionally, managing the complexity of building and pushing multiple images for different architectures can be time-consuming and error-prone. For instance, imagine a scenario where a customer initially uses an x64 (Windows) based operating system to run containerized applications. … Continue reading Efficient and Reliable Multi-Architecture Docker Image Building with BuildX

Python Operators

Python operator is a symbol that performs an operation on one or more values or variables. For example, the addition operator + adds two numbers together, the subtraction operator - subtracts one number from another, and so on. Python provides various types of operators such as arithmetic operators, comparison operators, logical operators, assignment operators, etc., each serving a specific purpose in manipulating data or controlling program flow.

Python Control Structures

Python first evaluates the if condition. If it's true, it executes the corresponding block of code and skips the elif and else blocks. If it's false, it moves to the next condition specified by elif. If that's true, it executes the corresponding block and skips the else block. If neither the if nor the elif conditions are true, the else block is executed. This demonstrates the sequential evaluation and branching behavior provided by if, elif, and else in Python.
