The evolution of diagramming in software mirrors the evolution of software development: from static and planned upfront → to lightweight and iterative → to automated and real-time. The 1968 “Mother of All Demos” by Douglas Engelbart wasn’t just a showcase of new technology—it was a glimpse into the future of how we interact with and visualize complex information, including software systems.

Playwright is a Microsoft-created NodeJS package with capabilities that are quite similar to Puppeteer. Both libraries enable you to automate browser-based tasks. With Playwright, you can launch or connect to a Chrome, Edge, Safari, or Firefox browser and exchange instructions. The DevTools protocol (for Chrome browsers) and a bespoke protocol (for Firefox and WebKit browsers) are used for these messages.

When running tests in a CI/CD pipeline, relying on external APIs can introduce instability, slow down execution, and even lead to failed builds due to rate limits or API downtime. Fortunately proxymock provides a solution by capturing API interactions and running a local mock server, enabling fully isolated and repeatable tests. In this blog, we’ll demonstrate how to integrate proxymock into a GitHub Actions CI pipeline using a demo app called outerspace-go.

In 2025, APIs continue to evolve, with gRPC and REST being two dominant architectures. Understanding their differences is crucial for modern software development. If you’re at all familiar with APIs, you know that REST APIs are the main API used, particularly when it comes to microservices and their applications. gRPC is a high-performance, binary, and strongly-typed protocol using HTTP/2, while REST is a simpler, text-based, and stateless protocol using HTTP with JSON/XML.

The List Index Out of Range error often occurs when working with lists and for loops. You see, in Python, when you attempt to access an element using an index that lies outside the valid index range of the list, you're essentially telling the program to fetch something that isn't there, resulting in this common error. For example, if you have a list with 3 elements: The valid indices for this list are 0, 1, and 2 (since Python uses zero-based indexing).

If you’re looking for an alternative to Microsoft App Center, this article will cover the top considerations, and how Sauce Labs handles these in its Mobile App Distribution offering.

Notifications muted. Social media logged out. Phone flipped face down. Sounds familiar? Well, in a world buzzing with digital distractions, many of us have tried going off the grid by deactivating apps, turning on airplane mode, or even attempting a full-blown digital detox. But let’s be honest, is that truly sustainable? For years, smartphones have been labeled as the root cause of stress and reduced productivity.

Model Context Protocol (MCP), introduced by Anthropic, is a new standard that simplifies artificial intelligence (AI) integrations by providing a secure, consistent way to connect AI agents with external tools and data sources. When we saw MCP’s potential, we immediately started exploring how we could bring real-time data streaming into the mix. With our long history of supporting open source and open standards, building an MCP server was a natural fit.

A data lakehouse is an innovative data architecture that blends the strengths of data lakes and data warehouses into a single, cohesive system. It retains the cost-effectiveness and flexibility of data lakes while incorporating the structured data management and performance optimization capabilities of data warehouses.

APIs power everything—from your favorite apps to critical business systems. But what happens when your API is subjected to large or unexpected traffic, security threats, or plunges under load? One weak link can destroy UX, destroy data or take down your service. API testing serves as your safety system beyond being a mandatory requirement. Faster development schedules and increased user demands during 2025 require organizations to make essential testing tool choices.
