To answer this, let's start with a well-known incident in civil engineering that highlights the importance of the P.Eng designation: the Quebec Bridge Collapse. This tragic event, where engineering miscalculations led to the bridge collapsing twice and resulting in the loss of 88 lives, underscored the critical need for professional accountability and rigorous standards. I also share an incident from our field to emphasize the point. In 2012, Knight Capital Group experienced a software glitch that caused a staggering $440 million loss in just 45 minutes. The glitch was due to a faulty software deployment—something that rigorous testing and professional oversight, like what P.Eng certification emphasizes, could have potentially prevented. In this article, I explore why P.Eng certification, which is highly valued in traditional engineering fields like civil and mechanical engineering, isn't as popular among software engineers. By examining real-world incidents in both software and civil engineering, I highlight how the rigorous standards, ethical obligations, and professional accountability associated with P.Eng certification can lead to safer, more reliable software systems. The goal is to foster a deeper understanding of the value of P.Eng certification and encourage more software engineers to pursue this prestigious credential. https://manistechmind.com/posts/jmeter https://manistechmind.com/posts/jmeter Sat, 25 May 2024 00:00:00 GMT Nariman Mani This article provides a comprehensive beginner's guide to using Apache JMeter for performance testing of distributed systems.

Although they share the goal of decomposing large applications into smaller, manageable pieces, they differ significantly in philosophy, implementation, and use cases. Microservices are characterized by small, independently deployable services that typically communicate via lightweight protocols such as HTTP or messaging queues. Each service in a microservice architecture often manages its own database, ensuring loose coupling and enabling high scalability and resilience. On the other hand, SOA traditionally operates with larger, more interdependent services that may share data storage and are commonly integrated through enterprise service buses (ESBs) using heavier communication protocols like SOAP. https://manistechmind.com/posts/nodejs https://manistechmind.com/posts/nodejs Sun, 21 Apr 2024 00:00:00 GMT Nariman Mani Node.js has revolutionized how developers think about and use JavaScript, a language traditionally confined to browser environments. Developed in 2009 by Ryan Dahl, Node.js extends JavaScript's capabilities beyond the browser, allowing it to run on servers and other environments. This transformation is rooted in Node.js's unique architecture, which repurposes Google’s V8 JavaScript engine—originally designed for Chrome—into a more versatile runtime environment. https://manistechmind.com/posts/abs-vs-encap https://manistechmind.com/posts/abs-vs-encap Sat, 20 Apr 2024 00:00:00 GMT Nariman Mani In software engineering interviews, a common topic that often surfaces is the distinction between abstraction and encapsulation.
