  • Camel K Brings Apache Camel to Kubernetes for Event-Driven Architectures – The New Stack

    Applications have increasingly relied on event-driven architectures (EDAs) in recent years, especially with the advent of serverless and microservices. EDAs decouple an event from the subsequent actions that may follow, as opposed to traditional linear architectures, where an event might be processed in that same code. This decoupling makes EDA processes able to be independently scaled and, while EDA does not strictly require microservices or serverless, the respective loose coupling and the on-demand nature is a perfect fit.

    In the cloud native world, the focus might often be on the serverless side of things, with Knative or Lambda taking the spotlight, but, as the name might imply, event-driven architecture is nothing without events. Apache Camel K takes Apache Camel, the fundamental piece of enterprise integration software that first came around as a sort of codification of the 2003 book Enterprise Integration Patterns, and brings it to Kubernetes, providing EDA with a multitude of event sources, explained Keith Babo, Director of Product Management at Red Hat.

  • Shenandoah in OpenJDK 17: Sub-millisecond GC pauses | Red Hat Developer

    Our primary motivation for the Shenandoah OpenJDK garbage collection (GC) project is to reduce garbage collection pause times. In JDK 12, we released the original Shenandoah garbage collector, which implements concurrent heap evacuation, which solved the major problem of cleaning (potentially large) heaps without stopping the application. This version was eventually backported to JDK 11. In JDK 14, we implemented concurrent class unloading, and in JDK 16, we added concurrent reference processing, both of which further reduced pause times in those garbage collection operations. The remaining garbage collection operation under pause was thread-stack processing, which we've solved in JDK 17.

    This article introduces the new concurrent thread-stack processing in Shenandoah GC. Processing thread stacks concurrently gives us reliable sub-millisecond pauses in JDK 17.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
