Red Hat/Fedora: Flatpak, Podman, Core Modernization

  • Flatpak extensions

    When I started packaging music applications in Flatpak, I was confronted to the issue of audio plugins: lot of music software has effects, software instruments and others implemented as plugins colloquially called VST. When packaging Ardour, it became clear that supported these plugins where a necessity, as Ardour includes very little in term of instruments and effects.

    On Linux there are 5 different formats: while LADSPA, DSSI and LV2 are open, VST2 and VST3 are proprietary standard, created by Steinberg, they are very popular in non-libre desktops and applications. Fortunately with somewhat open implementations available, they exist on Linux in open source form. These 5 audio plugins format work in whichever applications can host them. In general LV2 is preferred.

    Now the problem is that "one doesn't simply drop a binary in a flatpak". I'm sure there are some tricks to install them, since a lot of plugins are standalone, but in general it's not sanctioned. So I came up with a proposal and an implementation to support and build Linux Audio plugins in Flatpak. I'll skip the details for now, as I'm working on a comprehensive guide, but the result is that several audio applications now support plugins in flatpak, and a good number of plugins are available on Flathub.

  • Podman paves the road to running containerized HPC applications on exascale supercomputers

    Following the rise of Linux container use in commercial environments, the adoption of container technologies has gained momentum in technical and scientific computing, commonly referred to as high-performance computing (HPC). Containers can help solve many HPC problems, but the mainstream container engines didn't quite tick all the boxes. Podman is showing a lot of promise in bringing a standards-based, multi-architecture enabled container engine to HPC.

  • Core Modernization Leads the way to Business Success

    Over the years, insurers have grown organically, and through mergers and acquisitions, layering legacy infrastructure and meshing code that is often brittle to link core systems together. While modernizing systems is not an easy challenge to overcome, according to a recently released Forrester Consulting study commissioned by Red Hat, many in the industry understand that now is the time to do so. Insurers need to modernize these core systems to increase flexibility, gain cost savings, and be better able to address the growing digital needs of their policyholders. Let’s look at some of the key findings of this Forrester Consulting research study on modernizing the insurance roadmap.

    [...]

    Even though insurers recognize the need to modernize, there are challenges that can prevent them from doing so. Data migration, integration with upstream/downstream systems, cloud migration, and data conversion were cited among respondents as the top challenges they are facing.

    These challenges highlight both the insurance industry’s hesitation in moving to the cloud and what may happen if they don’t: falling behind the competition, failing to meet stakeholders’ needs, and not having the skills in place to eventually migrate.

    It is not enough to simply move core legacy systems to the cloud, it has to be optimized to maximize the most value, especially in light of the effort expended. While a cloud implementation with one or multiple providers is a step in the right direction, an open hybrid cloud infrastructure can aid core modernization and innovation by promoting a wider set of technology across the data center and public clouds. Technology teams would be freed to build new customer experiences, create and market offers, optimize operations, and manage talent across the enterprise using the same tooling for common tasks.

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.
