  • Fedora Classroom: RPM Packaging 101 - Fedora Magazine

    RPMs are the smallest building blocks of the Fedora Linux system. This session will walk through the basics of building an RPM from source code. You will learn how to set up your Fedora system to build RPMs, how to write a spec file that adheres to the Fedora Packaging Guidelines, and how to use it to generate RPMs for distribution. The session will also provide a brief overview of the complete Fedora packaging pipeline.

    While no prior knowledge of building RPMs or building software from its source code is required, some software development experience will be useful. The hope is to help users learn the skills required to build and maintain RPM packages, and to encourage them to contribute to Fedora by joining the package collection maintainers.

  • Application modernization patterns with Apache Kafka, Debezium, and Kubernetes | Red Hat Developer

    Ellen Ullman wrote this in 1998, but it applies just as much today to the way we build modern applications; that is, over time, with short-term plans, on top of legacy software. In this article, I will introduce a few patterns and tools that I believe work well for thoughtfully modernizing legacy applications and building modern event-driven systems.

    Note: Consider joining me for my session at Red Hat Summit 2021 on June 16, or at the Event-driven architecture virtual event on June 22. I will present about tools and patterns for application modernization at both sessions, and you will be able to ask me questions live.

  • Bee Travels: A microservices coding adventure | Red Hat Developer

    The microservice architectural style structures an application as a collection of services. These services are often large, monolithic applications that are broken into smaller services.

  • Project Shipwright and the future of Red Hat OpenShift builds | Red Hat Developer

    In Red Hat OpenShift, a build is the process of transforming source code and binaries into a container image that can run securely on a container platform. In this article, we'll introduce Project Shipwright, a framework for building container images on Kubernetes, and explore the future of builds in Red Hat OpenShift.

  • When IT careers stall: 5 tips to jump-start progress | The Enterprisers Project

    A career in software engineering or IT can sometimes feel like high-stakes gambling. New technologies and languages are always emerging and evolving, and new opportunities often involve taking risks and choosing between startups that could experience tremendous success – or flame out within months.

    The COVID-19 pandemic has only made things more treacherous. While many use moments of crisis to consider major life and career changes, a recent article from Harvard Business Review points out that in reality, “threatening situations prompt us to behave more conservatively,” leading to potentially stalled careers.

    The pandemic has had an even more acute effect on women in the workplace. According to a poll from CNBC and Survey Monkey, 22 percent of women have experienced a career setback within the past 12 months.

  • 4 ways CIOs can lead change management now

    These days, change is not novel. It is something that IT leaders have learned to embrace, accept, and even welcome, which has become particularly important over the past 14 months. We have had to be nimble and flexible in nearly every facet of our job and change management is no exception.

    Leading change management requires a solid foundation before moving forward with a strategy and these most recent challenges have accentuated the need for leaders to focus on being more intentional. This means being flexible with respect to employee schedules, understanding of the challenges they may have had working remotely or in their personal lives, and being deliberate about reaching out to them to make sure they’re happy, comfortable, and adjusting well to the different dynamics that the pandemic has introduced.

    Beyond the emotional well-being of employees, IT leaders need to ensure that employees have the tools necessary to be successful. Are they happy with the equipment they received at the start of the pandemic to facilitate remote work? Do they need anything else? Are they satisfied with the technical support that is available?

  • 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.
