The backbone of powerful applications lies in integrating diverse services, A tech requirement I’ve perfected countless times over my 18+ years of enterprise tech development. Two key TechConcept for enabling these integrations are webhooks and APIs (Application Programming Interfaces). Understanding the differences between them and knowing when to use each can significantly enhance your application’s…
In over 18 years of building enterprise-level tech solutions, one question I’m frequently asked by stakeholders is, ‘How do you ensure scalability?’ My response is always the same: through a disciplined, systematic approach as the system grows. For this, building scalable web services is essential for maintaining performance during traffic spikes and on demand future…
Error handling is critical in any application to ensure users receive clear, actionable feedback when something goes wrong. With over 18 years of tech solution-building experience, I’ve seen developers focus solely on writing code while neglecting error handling, leaving it to the testing team. However, by investing just a little effort into unit testing and…
Securing web services is crucial for protecting sensitive data and ensuring only authorized users can access your APIs. Without proper security measures, web services are vulnerable to attacks like unauthorized access, data breaches, and malicious exploitation. This guide covers key practices such as HTTPS, API keys, OAuth 2.0, JWT tokens, and Role-Based Access Control (RBAC)…
In new era of software development, the terms microservices and web services often come up when discussing scalable, flexible architectures. In my 18+ years of tech-building, I can affirm that while they may appear similar and are often used interchangeably in modern development, despite their similarities, they fulfils different roles and deliver distinct benefits. Understanding…
When building a web service, one of the first decisions you’ll need to make is choosing between REST and SOAP—the two primary protocols for communication between applications. In my 18+ year enterprise building application, both protocols allow us to exchange data over networks, they have distinct differences in terms of architecture, flexibility, and use cases.…
Web services are the backbone of many applications, enabling communication between different systems over the internet. With over 18 years of enterprise-building experience, I’ve worked hands-on with every aspect of web services throughout my tech career. From hotel bookings to mobile employee attendance updates to sending alerts on messaging app, web services drive these critical…
NIT Rourkela would be incomplete without mentioning the BackPost near Hall 5, a place that holds deep significance for the boys’ hostel residents, especially from 2nd to 4th year. It was where (2002-2006) we spent countless hours—discussing, Ragging, planning, dreaming, and exchanging ideas. This spot became a hub of conversation, where we talked about everything,…
Managing memory in Linux is crucial for ensuring optimal performance, especially on servers handling high loads. In my previous TechConcept, I highlighted one crucial aspect of memory management: swap memory, which plays a vital role when your system is running low on physical RAM. But when exactly does Linux use swap memory, and why is…
In 2005, during our third year at NIT Rourkela, my friends Alok, Amit, and I decided to bring something unique to our lives at Hall 5. NIT Rourkela wasn’t just about academics; it was a hub of cultures, traditions, and people from across India. Inspired by this diversity, we thought of installing a Saraswati idol…
Managing memory resources effectively is key to maintaining optimal performance for your EC2 instances. Leveraging my 18+ years of tech expertise, I have helped companies to cut costs dramatically through effective server optimizations like creating a swap file to prevent out-of-memory issues. Swap space acts as an extension of your server’s RAM by utilizing disk…
If your Linux servers are running slow or facing memory issues, it’s time for a tech cleanup. With 18+ years of experience building enterprise applications, I’ve learned that you must regularly get your hands dirty with the servers running your code. Armed with the right knowledge, you can quickly free up memory and enhance your…
Have you ever received a call claiming your bank card is locked and offering help to unfreeze it? This is a classic fake tech support scam, and in my 18+ years of tech experience, I’ve dealt with countless calls like these.
