Today, we’re announcing the public preview of TCP Proxy — a new way to expose TCP ports publicly. Until now, services on Koyeb could only be publicly exposed via HTTP, HTTP/2, WebSocket, and gRPC protocols. TCP-based workloads were limited to private access within the mesh network for service-to-service communication. With TCP Proxy, that changes. You can now make any TCP service publicly accessible with minimal configuration.

Xray’s Requirement Coverage refers to how defined requirements inside a specific project are being validated by tests. Each requirement – whether Jira Story, Epic or Feature - should be connected to one or more test cases. When these tests are being executed and the results are being reported, the coverage status of the requirements automatically updates. Bottom line, only creating tests is not enough.

In a technologically dominated world, producing top-notch software isn’t merely a competitive edge – it’s a must. Whether creating a mobile application, a website, or a large-scale enterprise system, consumers anticipate that your software be secure, responsive, and flawless. That’s where Quality Assurance (QA) Testing comes in. It doesn’t just make your software work – it work well, do what users need it to do, and meet world-class standards of excellence.

Apache Parquet has become the de-facto standard for storing data used in analytics workloads, and has seen very broad adoption as a free and open-source storage format. When used as the underlying storage layer for Apache Iceberg, Parquet is also a foundational building block in modern lakehouse architectures, which enable warehouse-like capabilities on cost effective object storage. Let’s take a closer look at what Parquet actually is, and why it matters for big data storage and analytics.

For years, Automock was a popular framework for defining mocks and stubs in backend test environments. As technology has evolved, new methods and techniques for streamlining the simulation of dependencies in testing have emerged. That's why Automock has been succeeded by Suites, a more modern and robust library. In this article, we'll explore the transition from Automock to Suites, understand what Suites offers, and see it in action in NestJS through a complete example.

In this series, we will take a close look at the architecture of ActiveStorage for Rails. In this first part, we will examine how ActiveStorage treats uploaded data and how to extend this process. The second part will explore how to augment the presentation of uploaded assets. But first, let's quickly define what ActiveStorage does.
