  • Optimal flow: Building open organizations where leaders can emerge

    Previously in this series on open organizations and talent management, I’ve discussed the importance of cultivating an organization’s open leaders by getting out of their way and letting them flourish. As someone invested in developing your organization’s next generation of leaders, know that your goal here isn’t to be entirely “hands off”; instead, your goal is to spend time building the systems and processes that help new leaders find their footing and unleash their passion. The truth is that leadership talent rarely develops on its own.

  • Automating the testing process for SystemTap, Part 1: Test automation with libvirt and Buildbot

    Over the past year, I have been implementing an automated infrastructure to test the SystemTap project and to collect and analyze the test results. SystemTap is a scripting language for creating instrumentation to observe a live running Linux kernel and user-space applications. The SystemTap language translator produces Linux kernel modules. These modules depend on internal details of the Linux kernel that vary significantly between different versions of Linux.

    The process of developing the SystemTap project and maintaining it for a wide range of Linux kernel versions requires a strategy to detect and fix unexpected bugs. Bugs can arise not only from changes in the SystemTap project, but also from changes in newer versions of the Linux kernel.

    In order to verify the safety and correct behavior of SystemTap, the SystemTap project includes a test suite based on the DejaGnu framework. However, up to now there was no system for running this test suite each time someone made a commit to the SystemTap Git repository. An infrastructure that automatically runs the test suite and reports new test failures would be very helpful for detecting and fixing bugs as early as possible during the SystemTap development process.

    This article is the first of two articles summarizing the tools that I developed and used to automate the process of testing SystemTap and detecting test failures. For the purpose of these articles, I consider the testing process to consist of seven steps. I describe the implementation for each of these steps and finish by summarizing my key design ideas and outlining potential future improvements.

    The ideas presented in these articles could be useful for other open source projects with complex testing requirements.

  • Fedora Community Blog: Contribute to Fedora Kernel 5.12 Test Week

    The kernel team is working on final integration for kernel 5.12. This version was recently released and will arrive soon in Fedora. As a result, the Fedora kernel and QA teams have organized a test week from Sunday, May 06, 2021 through Sunday, May 16, 2021. Refer to the wiki page for links to the test images you’ll need to participate. Read below for details.

  • Why Windows and Linux line endings don’t line up (and how to fix it)

    I recently wrote a few automated database-populating scripts. Specifically, I am running Microsoft SQL Server in a container in a Kubernetes cluster—okay, it’s Red Hat OpenShift, but it’s still Kubernetes. It was all fun and games until I started mixing Windows and Linux; I was developing on my Windows machine, but obviously the container is running Linux. That’s when I got the gem of an error shown in Figure 1. Well, not so much an error as errant output.

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.
