Boosting the scalability of your backend applications often means rethinking how you manage asynchronous data. That’s where reactive programming comes into play: a paradigm that treats data streams as first-class citizens, allowing your code to respond to data changes as they occur. While Node.js wasn’t built with reactive programming in mind, libraries like RxJS and Bacon.js support that approach.

In parts one and two of this series, we familiarized ourselves with the ins and outs of Showcase. Now, we'll dive into samples, Showcase's main feature. Samples show how a component can be used in a real application.

We are noticing that some of our requests are starting to get slow and server load increases. Checking the process list of our server, for example with htop reveals that our FPM workers are taking up all of our CPU time. Checking the health with our basic toolset of lsof to show open network connections and strace to show syscalls does not reveal any activity. This means that the workers are spending time processing data without any externally visible activity.

AI adoption is accelerating across every industry, from customer service and marketing to finance and retail, and we’re still far from its peak. Many organizations have already begun integrating AI agents into their business operations. A key aspect of this transformation is the use of AI agents, whether purpose-built or off-the-shelf, to assist with or even replace tasks traditionally handled by humans.

If you’re using Microsoft Dynamics 365 — whether it’s for enterprise resource planning (ERP), customer relationship management (CRM), or any other business application — data privacy and compliance on the platform should remain a top priority.

Automotive infotainment systems are a core component of the modern driving experience. As these systems expand in features and complexity, the challenges for the software design teams behind them also increase. For automotive leaders, designers, and technicians, staying ahead means.

With Xcode 26, Apple has finally introduced Xcode Compilation Caching: a major leap forward for iOS developers, who no longer have to wait around for slow builds while their CI pipelines recompile code that hasn’t changed. At Bitrise, our Build Cache product already supports Bazel and Gradle, so the logical next step was to introduce support for compilation caching in Xcode. In this blog post, we’re lifting the hood on how we built this new feature.
