  • Ansible Beginner’s Guide: Automate the Pain Away

    Way back in the day, humanity created computers to help make our lives easier. In a lot of ways, they have; in others, its made life much more tedious, especially for the SysAdmin. What use to be a mainframe has turned into hundreds of servers, containers, and virtual machines spread across data centers, clouds, and even laptops!
    Never fear, Infrastructure as Code (IaC) is here. Tools like Ansible have been around for over a decade or more but the past few years have really picked up speed. Ansible is a simple, efficient approach to automating and standardizing our environments while cutting down on the time, increasing the reliability, and removing the human error factor from operations and deployments!

  • Open Practice Library basics: Planning and Executing

    Planning and executing is about understanding what can be delivered, when, and how to get it done. Previously in this series, we worked through some practices to define our team’s work. In this post, we will talk about determining the level of effort for stories and planning and executing the next sprint/iteration.

    Relative Sizing or Story Pointing

    Relative Sizing, or Story Pointing, is a practice where the team determines the level of effort required to complete a given task relative to other tasks in the backlog.

    Sizing a story has less to do with how much time the team thinks is necessary to complete the task and more to do with the amount of effort required. Anyone interested can find many articles online that deal with the notoriously bad estimation of software engineers, so I won’t go into too much detail about that here.

    While a story should be able to be completed within the span of a single sprint, time is not the sole determination of the level of effort.

  • What next-generation leaders expect: the choice to work openly

    Earlier in this series on talent management, I argued that emerging, talented leaders need space to flow to those places in the organization where they add value based on their unique talents and intrinsic motivations. If the organization's management and senior management set the right examples, extend trust, and listen, they can greatly accelerate the organization's transformation to a more open culture. But talent needs access to an organization's cliques and inner circles, its boards and executive teams, to really kickstart the kind of collaboration and mutual learning that will move the organization forward and create sustainable succession.

    [...]

    In this series on open organizations and talent management, I've explained how the speed and strength of your organization will determine your success in a new economic environment, one where new ideas are toppling some longstanding older ideas. These new ideas spring from the creativity and resourcefulness of your employees, but they can only do that in a safe and more open working environment. So we urgently need more focus on balancing people's needs and the business' needs inside our organizations. Your goal is igniting passion and performance, and you're able to do this when people feel free and invited to contribute to the organization's purpose—not when they're commanded to by command-and-control structures. Unfortunately, too few organizations don't strike that balance. When they don't, they see the consequences: loss of competitive position in this rapidly changing market.

    Surviving will mean transitioning to a more open organizational model, one built around a leadership style that doesn't rely on formal authority. It also calls for decision-making that considers not only reason but also on feeling, on heart. That sense of balance extends to managers, who need to balance their expectations with those of emerging leaders.

  • 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.
