Regression testing is a software testing practice that ensures recent code changes do not negatively impact the existing functionality of an application. It involves re-running previously executed test cases to verify that new updates - such as bug fixes, enhancements, or feature additions - do not introduce defects into previously working software components. The primary goal of regression testing is to maintain software stability while allowing continuous improvements.

As your business grows, so does your data. And if you’re running Microsoft SQL Server, you’ve likely faced the challenge of managing storage in a way that doesn’t break the bank but keeps your applications running smoothly. It’s a balancing act that many IT professionals and business leaders struggle with daily. We hear from numerous mid-sized companies that hit a wall with their Microsoft SQL Server database.

Modern companies generate large volumes of data, but often the internal users who need that data to do their jobs—data engineers, managers, business analysts, and developers—can find it challenging to quickly figure out answers to their questions. Apache Kafka is a powerhouse for real-time data processing of high-throughput workloads, and many organizations use Kafka to enable self-service access to data streams.

Manual testing gets old fast. You end up clicking through the same workflows over and over, and it’s easy to miss bugs when you’re going through dozens of test cases. Automated testing tools handle the repetitive stuff for you, running tests in the background while you work on actual development. This guide looks at some solid automated testing tools for 2025 that can help streamline your testing process.

AI is everywhere. Depending on who you ask, it’s either making developers obsolete, or it’s just hype. But for those of us who’ve actually used AI tools in real-world engineering workflows, especially in complex distributed systems, the truth lies somewhere in between. At Multiplayer, we’ve spent the past few years exploring how AI can—and can’t—help solve two of the most persistent challenges in distributed systems: documentation and debugging.

Building a faster, more reliable, scalable, and efficient API requires the use of an appropriate framework and tools. The communication protocol used to build an API usually has a significant impact on its effectiveness and speed. Jump in with us and learn how to build a gRPC Node.js API.

As cloud native applications grow, managing resource usage and controlling costs becomes increasingly complex. Choreo's Cost Optimizer addresses this challenge by providing AI-driven insights and actionable recommendations, enabling developers and organizations to streamline resource utilization and reduce unnecessary expenditures.

In the world of modern web applications and APIs, authentication and authorization mechanisms are critical. Whether you’re building a RESTful API, working with OAuth2, or integrating third-party services, you’ve likely encountered the term "Bearer Token." But what exactly is a bearer token? How does it work? And one of the most common questions: Can you reuse a bearer token?

Go, with its simplicity and strong concurrency model, is a popular choice for building CLI tools. Cobra and Viper are two powerful libraries in Go for building command-line interfaces and managing configuration, respectively. They are designed to work seamlessly together, offering a robust solution for developing feature-rich CLI applications. To understand how they work internally and complement each other, let’s dive deeper into their architecture and how they interact.

Bugs that slip through testing and reach production can derail even the most well-planned software release. The key to avoiding costly fixes and downtime? Catching issues early – before they impact users. Pre-production testing is vital, but without the right level of error visibility, identifying the root cause of failures can feel like searching for a needle in a haystack.
