  • Fedora BoF at Ohio LinuxFest 2019

    I held a Fedora Birds-of-a-Feather (BoF) session at Ohio LinuxFest in Columbus, Ohio on November 1. Ohio LinuxFest is a regional conference for free and open source software professionals and enthusiasts. Since it’s just a few hours drive from my house, it seemed like an obvious event for me to attend. We had a great turnout and a lively conversation of the course of an hour.

    The session started a little slowly as many people were still in the keynote. But a few minutes later, the room was nearly full. I didn’t take a count, but at the peak, we probably had about two dozen attendees. Some were existing Fedora users and some were there to learn more about Fedora.

    I didn’t plan any particular content, since I wanted to let the group drive the discussion based on what was interesting to them. We ended up talking about documentation a fair amount. Two of the attendees created a FAS account that weekend so they can start contributing to the docs! Several more claimed the OLF BoF badge, and I sent them all a follow-up email directing them to the Join SIG’s Welcome page.

    In addition to docs, we talked about the general Fedora release process—how we determine our schedule and how we decide when to release. I brought some USB sticks with Fedora 31 Workstation for people to try. And of course I had stickers, pens, and pins to give away.

  • Java Applications Go Cloud-Native with Project Quarkus

    Getting Java applications to run well in a cloud-native environment hasn't always been easy, but that could soon change thanks to the open-source Quarkus framework.

  • Open Liberty Java runtime now available to Red Hat Runtimes subscribers

    Open Liberty is a lightweight, production-ready Java runtime for containerizing and deploying microservices to the cloud, and is now available as part of a Red Hat Runtimes subscription. If you are a Red Hat Runtimes subscriber, you can write your Eclipse MicroProfile and Jakarta EE apps on Open Liberty and then run them in containers on Red Hat OpenShift, with commercial support from Red Hat and IBM.

  • Tracing Kubernetes applications with Jaeger and Eclipse Che

    Developing distributed applications is complicated. You can wait to monitor for performance issues once you launch the application on your test or staging servers, or in production if you’re feeling lucky, but why not track performance as you develop? This allows you to identify improvement opportunities before rolling out changes to a test or production environment. This article demonstrates how two tools can work together to integrate performance monitoring into your development environment: Eclipse Che and Jaeger.

  • 3 key strategies for becoming a diversity and inclusion leader

    Issues of inclusivity also make workplaces challenging for underrepresented developers. Women are 45% more likely to leave their jobs in the first year than men. While some point to factors outside the workplace to account for this, we know that women tend to leave their roles because of feelings of isolation and poor sponsorship. This exacerbates the $16 billion-a-year problem the tech industry faces in hiring and retraining costs.

  • How to contribute to Kubernetes if you have a fulltime job

    I started contributing to Kubernetes (K8s) in October 2018, when I was working on the Product Security Incident Response Team at IBM. I was drawn to distributed systems, but I couldn't work with them in my day job, so my mentor, Lin Sun, suggested I contribute to open source distributed systems in my spare time. I became interested in K8s and have never looked back!

  • 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.
