  • Top 5 Linux man command options for browsing man pages | Enable Sysadmin

    Searching through the seemingly endless repository of information online has been, and always will be, a useful tool in the pocket of any sysadmin. The vast archive of collective wisdom and shared experiences is a tribute to The Open Internet. Having access to such a huge repository of information is not something any sysadmin takes for granted. That said, there are certainly advantages to knowing how one can find answers to a problem without having to rely on the World Wide Web for every question or problem. For one, you might find yourself working in an air-gapped environment in which access to the Internet isn't possible. Or, if you have ever sat a Red Hat exam, you're aware that access to the Internet is also not an option, and knowing how to look things up fast may mean the difference between a pass and no pass result.

  • What is your Linux server hardware decommissioning process? | Enable Sysadmin

    I've seen a broad range of hardware decommissioning (decomm) processes in my years as a sysadmin. It can be as simple as an email with a dire warning about a soon-to-be decommissioned system all the way up to a multi-layered, multi-month, multi-approver process that makes government red tape seem like a pale pink by comparison.

    The process in the last two companies I worked in, decommissioning was a 30-day process that started with notifications, a so-called "Scream" test, and a final shutdown, unracking, and palletizing for disposal. I love the term "Scream" test. This part of the process involves unplugging the system from the network for two weeks to see if anyone screams about a lost service. It's effective and I've had my share of opportunities to reverse a decomm for last-minute file recovery and then to restart the process again.

  • Installing and using Dynatrace to prevent outages

    In this post we're going to look at the next part of our fictional company's journey to digital transformation. Over the past several months Davie Street Enterprises’ (DSE) digital transformation has progressed quickly with much success. Now it's time to tackle predicting and preventing, if possible, outages and improving user experience.

    Ranbir Ahuja, Senior Director of Operators, has been following the efforts with much curiosity. For the most part, Ahuja is excited at the progress yet is concerned that from his perspective one of the largest single drivers for this transformation hasn’t been directly addressed.

  • Red Hat Is Hiring Even More Graphics Engineers

    Red Hat is now hiring two more graphics engineers working on the Linux graphics drivers. This will be focusing on Red Hat Enterprise Linux, Fedora, and upstream graphics drivers for the open-source code around Intel, AMD, and NVIDIA. Remote work is a possibility. The second of these job openings will have some exposure to the ARM graphics scene and tie in at least some extent to Red Hat's growing automotive / infotainment efforts.

  • Christian Schaller: New opportunities in the Red Hat Desktop team

    So we are looking to hire quite a few people into the Desktop team currently. First of all we are looking to hire two graphics engineers to help us work on Linux Graphics drivers. The first of those two jobs is now online on the Red Hat jobs site. This is a job in our core graphics team focusing on RHEL, Fedora and upstream around the Intel, AMD and NVidia open source drivers. This is an opportunity to join a team of incredibly talented engineers working on everything from the graphics system of the Linux kernel and on the userspace bits like Vulkan, OpenGL and Wayland. The job is listed as Senior Engineer, but for the right candidate we have flexibility there. We also have flexibility for people who want to work remotely, so as long as there is a Red Hat office in your home country you can work remotely for us. The second job, which we hope to have up soon, will be looking more at ARM graphics and be tied to our automotive effort, but we will be looking at the applications for either position in combination so feel free to apply for the already listed job even if you are more interested in the second one as we will discuss both jobs with potential candidates.

  • 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.
