  • Automated migration from JBoss A-MQ 6 to Red Hat AMQ 7 on Red Hat OpenShift

    Since Red Hat OpenShift Container Platform was first released, Red Hat Middleware products were provided to deploy on it and help developers to build more complex solutions. Messaging Brokers are a very important piece in most new application architectures, such as microservices, event sourcing, and CQRS. Red Hat JBoss A-MQ was provided from the beginning to deploy Messaging Brokers on Red Hat OpenShift easily.

    Red Hat AMQ 7 is the latest version of a high-performance, scalable, and multi-protocol broker based on the Apache ActiveMQ Artemis open source project. It is also available as a containerized image for use with Red Hat OpenShift, so it allows developers to quickly deploy messaging brokers in a cloud environment.

  • A guide to the open source distributed tracing landscape

    Getting started with distributed tracing can be a daunting task. There are many new terms, frameworks, and tools with apparently overlapping capabilities, and it’s easy to get lost or sidetracked. This guide will help you navigate the open source distributed tracing landscape by describing and classifying the most popular tools.

    Although tracing and profiling are closely related disciplines, distributed tracing is typically understood as the technique that is used to tie the information about different units of work together—usually executed in different processes or hosts—in order to understand a whole chain of events. In a modern application, this means that distributed tracing can be used to tell the story of an HTTP request as it traverses across a myriad of microservices.

    Most of the tools listed here can be classified as an instrumentation library, a tracer, an analysis tool (backend + UI), or any combination thereof. The article “The difference between tracing, tracing, and tracing” is a great resource in describing these three faces of distributed tracing.

    For the purposes of this guide, we’ll define instrumentation as the library that is used to tell what to record, tracer as the library that knows how to record and submit this data, and analysis tool as the back end that receives the trace information. In the real world, these categories are fluid, with the distinction between instrumentation and tracer not always being clear. Similarly, the term analysis tool might be too broad, as some tools are focused on exploring traces and others being complete observability platforms.

  • Dell Launches Linux-Loaded Precision 3540 Laptop Starting At ~$700 USD

    While the new Dell XPS 9380 Developer Edition is a beauty and offers very capable performance, if the price is too much, Dell has launched their "budget" Mobile Precision laptops now with Ubuntu Linux options. 

    The Dell Precision 3540 is the first of these new developer edition laptops. The Dell Precision 3540 starts at $702 USD for a Core i5-8365U model with UHD Graphics 620, 15-inch 1366x768 display, 4GB RAM, and 500GB HDD. There's a $67 savings in going for Ubuntu Linux over Microsoft Windows 10. Overall it's not too bad for a low-tier laptop though personally would have issues with the 4GB of RAM and 1366x768 display in 2019.

  • Latest Dell XPS 15 9575 BIOS updates result in unresponsive input devices when logging in to Linux

    Last year we reported about a bug in a BIOS update to the Dell XPS 15 9575 2-in-1 that caused the trackpad to have a mind of its own. Now, we again get to see a similar bug with the the latest BIOS version for the XPS 15 9575 convertible that affects the touchpad and keyboard responsiveness for users trying to logon to Linux. The bug was filed at the end of March 2019 but the problem appears to persist even with the latest firmware released at the end of April.

    User Joe Barnett has filed a bug report on the Ubuntu Launchpad bug tracker stating that the touchpad and keyboard in the XPS 15 2-in-1 become unresponsive when logging in to the Gnome Display Manager (GDM) on Ubuntu 19.04 when the laptop is flashed with BIOS version 1.4.0 or above.

  • 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.
