  • Raptor CS: Fully Owner Controlled Computing using OpenPOWER | Random thoughts of Peter 'CzP' Czanik

    This week I am talking to Timothy Pearson of Raptor Engineering. He is behind the Talos II and Blackbird boards for IBM POWER9 CPUs. His major claim is creating the first fully owner controlled general purpose computer in a long while. My view of the Talos II and Blackbird systems is that these boards helped to revitalize the open source ecosystem around POWER more than any other efforts (See also: Most open source developers I talked to say that coding on a remote server is just work. Doing the same on your local workstation adds an important ingredient: passion. This is why the re-introduction of POWER workstations was a very important step: developers started to improve support for POWER also in their free time, not just in their regular working hours. I asked Tim how the idea of creating their POWER board was born, how Covid affected them and also a bit about their future plans.

  • 7 books to improve your EQ and communications skills

    The challenges of the past few years have prompted many leaders to take a fresh look at their emotional intelligence (EQ) skills. It’s an area that’s worth focusing on, especially for those who want to advance their career by offering qualities that go beyond technical skills.

    Here are my top picks for readers looking to improve their EQ. While some of these were published years ago, they still hold relevance today.

  • How to explain modern software development in plain English

    Some principles of software development – also known as programming – don’t ever really change.

    Programming is problem-solving. Programming is communication, albeit with a machine. Programming is what makes that machine – and millions of others – usable to the masses. Programming is imperfect, always a work in progress. Programming is work.

    Preface the longstanding term with the word “modern,” however – as in, modern programming or modern software development – and you are in fact saying that things have changed. It might suggest there could be pre-modern and even ancient phases of software development, as if we’re talking about art history instead of computers and software.

    The term “modern software development,” in particular, gets thrown around with semi-regularity. It’s indeed used to convey that the speaker (or writer) is referring to software that is being built and operated today as opposed to at some unspecified point in the past. While some core principles might not waver, much of today’s software is being built differently – and more quickly – than in the past.

  • The State of Kubernetes Security in 2022

    Kubernetes is the de facto standard when it comes to container orchestration and management at scale, but adoption is only one piece of Kubernetes strategy. Security plays a huge role in how organizations use cloud-native technologies, and is typically much trickier to address than simply spinning up and running containers. Red Hat’s The State of Kubernetes Security for 2022 examines the security challenges organizations face when it comes to cloud-native development and how they address these challenges to protect their applications and IT environments.

  • Red Hat releases open source StackRox to the community [Ed: Red Hat is once again outsourcing to Microsoft/NSA proprietary prison, then boasts about it]

    Red Hat is excited to announce that Red Hat Advanced Cluster Security for Kubernetes is now available as an open source project: StackRox. Kubernetes users and developers can join the community and test and contribute to the codebase of the project on GitHub.

    Kubernetes is at the foundation of cloud-native development and one of the fastest growing open source projects. According to the Cloud Native Computing Foundation (CNCF) 2021 survey, 96% of respondents reported that they are using or evaluating Kubernetes. The open sourcing of Red Hat Advanced Cluster Security gives organizations a way to help shape the future of how they can better manage and protect their Kubernetes environments.

  • Kube by Example adds five learning paths and previews new community forum

    It’s been nearly a full year since we relaunched Kube by Example, the free online training portal for technical professionals looking to learn more about Kubernetes and other cloud-native technologies. Since then, Kube by Example has continued to grow in many ways.

  • Application Modernization Report Shows Need For Kubernetes-specific Migration Tooling

    Konveyor is a community of people passionate about helping others modernize and migrate their applications to the hybrid cloud by building tools, identifying patterns, and providing advice on how to break down monoliths, adopt containers, and embrace Kubernetes. To do so, the Konveyor community is currently working on five projects to help users rehost, replatform, and refactor their applications to Kubernetes.

  • Manage JFR across instances with Cryostat and GraphQL

    Cryostat manages the monitoring of Java applications using Java Flight Recorder (JFR) in the cloud. Cryostat 2.1 includes support for GraphQL to control flight recordings on multiple applications, containers, and Kubernetes pods, with powerful filtering capacities. This article discusses the motivation for adding GraphQL support, shares some examples of queries along with expected results, and takes a look at the underlying web requests on the GraphQL endpoint.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
