Mattermost v7.4 is generally available today. The following new features are included (see changelog for more details).

Digital data is everywhere, and its sheer volume and ambiguity often make it challenging for us humans to analyze. That’s why we use a special branch of AI called artificial intelligence for IT operations (AIOps) to reveal the deeper structure of copious data. AIOps sits at the intersection of big data and machine learning to improve the efficiency of IT operations.

gRPC is an inter-process communication protocol used in high-performance applications in cloud computing, Internet of Things (IoT), mobile computing, and microservices environments. This article examines how gRPC works, how to use it, and how it compares to other popular API architectures. It also discusses a unique use case where gRPC excels.

When you maintain an internal or public-facing API, the API documentation is an important component of the overall user/developer experience. One of the industry standards for such documentation is the OpenAPI specification. With an OpenAPI specification, you define a contract that specifies how your API should behave, but nothing stops the parties involved from breaking such a contract (e.g., using a wrong implementation or invalid input).

Welcome to the Fall 2022 edition of Open Source Matters: our regular publication about the latest happenings in open source! Let’s dive into the news.

Resolving the incident is only half the battle when it comes to responding to incidents. For many teams, incident communication is an afterthought, leaving stakeholders inside and outside the organization guessing what happened. But ensuring that important information about the incident is disseminated clearly and quickly is essential.

The concept of containerization helps you run applications as lightweight virtual machines. As a web developer, setting up local development environments can be tiresome. However, using tools like Docker and Kubernetes gives developers an upper hand to quickly set up and deploy applications. This guide uses Docker to deploy a React app to Kubernetes.

Mattermost v7.3 is generally available today. The following new features are included.

In 2011, a Netflix engineering team introduced the concept of chaos engineering with its release of Chaos Monkey. This was initially an in-house tool developed to orchestrate fault injection that Netflix eventually made open source. However, the reliance of Chaos Monkey on Spinnaker, another Netflix engineering innovation, establishes some limitations.

Communication within organizations has evolved from email threads to real-time chats. With the vast potential of real-time messaging, organizations are beginning to explore how they could make these chat applications do more. We now even have a name for this phenomenon — ChatOps. To get a taste of the power of ChatOps in action, let’s build a ChatOps bot that sits in a Mattermost channel with Errbot.
