Over the last decade, data has been hailed as the new oil, the new gold, the new currency, the new soil, and even the new oxygen. All these comparisons drive home the same point: data is important. If you’re running a business today, you need data for informed decision-making and strategy development. However, reliably extracting this data is a constant responsibility.

Black Friday is when eCommerce sites face their toughest critics: deal-hunting shoppers with zero patience for glitches. Were you aware that 47 of visitors anticipate a website to finish loading within 2 seconds? Even more concerning, half of the visitors will leave a sluggish website and switch to a competitor. One crash during busy times can lead to significant financial loss and permanent harm to your brand's image.

Business leaders are worried that despite their fervent enthusiasm for building innovative solutions, they haven’t been able to explore even half of the possibilities that digital has to offer. This anxiety has made CXOs desperate to associate with keywords like Generative AI, multi-cloud, SaaS, and more. However, accommodating these big technologies in a rush often comes at the cost of quality.

Today’s energy systems face a critical challenge: they often operate in isolation, with little real-time communication between key components like wind turbines and transformers. This lack of connectivity leaves gaps in performance optimization, predictive maintenance, and seamless grid management. With no existing technology robust enough to bridge these divides, the sector remains vulnerable to disruptions and inefficiencies.

AI is becoming a part of our everyday lives, and in the software testing industry, it is starting to show its impact as well. Traditional testing methods can often happen at a later stage of the development life cycle, which may present challenges for meeting the demands of modern software delivery. This is where shift-left testing comes to shine. This testing methodology has become one of the most used strategies for delivering high-quality software without missing bug findings along the way.

App Center, a popular CI/CD platform from Microsoft, announced it will close its doors on March 31st 2025. This has left many mobile developers and teams looking for an alternative. Probably the most affected is the React Native community who have relied on App Center because of its OTA updates with CodePush.

JSON, which stands for JavaScript Object Notation, is a lightweight data-interchange format that offers a way to store and exchange data that is simple to read and write. It can be viewed as a format for organizing data so that different programs can understand it. It is frequently used for transmitting data in web applications between a server and a client. JSON logs are log entries that are formatted in JSON.

In today’s digital age, data has evolved from being a mere byproduct of business processes to becoming the cornerstone of strategic decision-making. Yet, for many organizations, unlocking the full potential of their data remains a significant challenge. Traditional data analytics models often create bottlenecks, relying heavily on overextended IT departments to provide insights, which delays decision-making and limits agility.

As digital transformation accelerates, the importance of specialized testing services has grown exponentially. While still relevant, traditional functional testing no longer suffices for businesses aiming to deliver robust, seamless applications that meet modern user demands. Specialized testing—spanning performance, cognitive, and UX domains—is now critical in ensuring digital ecosystems’ resilience, security, and usability.

In the previous part of this series, we discovered how to create persistent connections in Rack in theory, but now we'll put what we learned into practice. The web has two formalized specifications for communication over a persistent connection: server-sent events (SSEs) and WebSockets. WebSockets are widely used and highly popular, but SSEs are far less well-known. Let's explore them first.
