Fedora and IBM/Red Hat Leftovers

  • Fedora 36 Establishing ELN-Extras, Fedora 37 To Retire ARMv7 - Phoronix

    he Fedora Engineering and Steering Committee (FESCo) has signed off on more feature work for the current Fedora 36 cycle as well as Fedora 37 due out toward the end of next year.

    Arguably most interesting from the latest batch of approved changes is Fedora 36 establishing ELN-Extras. ELN as "Enterprise Linux Next" continues going strong with the various Fedora / Red Hat / CentOS organizational changes. ELN-Extras now is a new build target similar to ELN but closer in function to Extra Packages for Enterprise Linux (EPEL). ELN-Extras will be the target for preparing and maintaining packages that are planned for EPEL N+1 while ELN is still targeting RHEL N+1.

  • [Solved] Error rpmdb damaged header in Fedora, RHEL - OSTechNix

    Today I tried to update all packages with sudo dnf --refresh upgrade command in my Fedora 35 desktop. During the package update, I encountered with this issue - error: rpmdb: damaged header #5904 retrieved -- skipping.

    I kept getting this error a lot. I couldn't update the Fedora system. After a couple web searches, I found that the RPM database is corrupted for some reason.

    If you ever stuck into a situation like mine, you can easily solve the "rpmdb damaged header" error by rebuilding the RPM database as shown in the following steps.

  • Visualize your Apache Kafka Streams using the Quarkus Dev UI

  • Digital transformation: 4 strategies to set the right goals

    Digital transformation initiatives should be comprehensive and defined by a vision that leads organizations toward more efficient, data-driven, and goal-oriented performance. Digital transformation requires a clear end goal as well as detailed benchmarks to help lead teams in the right direction. The more specific and considered the goals and benchmarks, the more likely the organization is to see progress and ultimate success.

    As your organization establishes its digital transformation vision, the most important question may be whether it is goal-oriented or outcome-oriented. While a goal-based perspective considers the big picture and long-term priorities, focusing on outcomes will prioritize steady progress and finding opportunities for incremental improvement on existing processes. The outcomes of that progress – cost savings or reduced workload, for example – help to build buy-in and momentum for the broader transformation.

    Regardless of your overall approach, it’s important to use frequent, consistent measurements to ensure that work is moving forward. Regular measurement helps you identify your most successful efforts, which you can then replicate in other areas of the business. It’s also essential to not only review your goals regularly but also refine them. Benchmarks that made sense in January may no longer be ambitious enough after review in July.

  • Automation strategy: 6 key elements

    IT automation often occurs organically – a sysadmin writing Bash scripts to simplify redundant tasks in their day-to-day job, for example. This kind of incremental automation doesn’t preclude big-picture vision and planning, however.

    Automation strategies should be incremental. As recently noted by Red Hat technology evangelist Gordon Haff, incremental progress is part of the attraction. It’s in automation’s DNA.

    “This is automation through the lens of traditional system admins and even site reliability engineers in many cases,” Haff says. “Do something manually more than once and automate it so that you don’t have to, ever again.”

    This is a perfectly reasonable progression that can also be aligned with a higher-level strategy.

  • Tech careers: Hiring tips for candidates and leaders | The Enterprisers Project

    Tech careers are hotter than ever these days, but candidates still need to stand out in this competitive field. According to the Bureau of Labor Statistics, technology-related jobs will grow much faster than jobs in most other fields over the next decade. So, what does an ideal candidate look like at a startup or a large established corporation?

AS400 - Russell Coker

  • AS400 - Russell Coker

    The IBM i operating system on the AS/400 is a system that runs on PPC for “midrange” systems. I did a bit of reading about it after seeing an AS/400 on ebay for $300, if I had a lot more spare time and energy I might have put in a bid for that if it didn’t look like it had been left out in the rain. It seems that AS/400 is not dead, there are cloud services available, here’s one that provides a VM with 2GM of RAM for “only EUR 251 monthly” [1], wow. I’m not qualified to comment on whether that’s good value, but I think it’s worth noting that a Linux VM running an AMD64 CPU with similar storage and the same RAM can be expected to cost about $10 per month.

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.
