  • Linux Getting Fixed Up For Handling Pointing Sticks On Some Touchpads

    For input devices on some laptops that are a combination of a pointing stick and touchpad, the Linux kernel's multi-touch driver will finally begin handling them correctly.

    At least for Synaptics and Elan devices that offer a combination of a pointing stick and touchpad, the Linux kernel has been ignoring the input events from the pointing stick. But with Linux 5.8 that will change in properly handling the combo multi-touch devices via the hid-multitouch driver and this change is set to be back-ported as well to the various Linux kernel stable series being supported.

  • Mesa 20.1 Features Include Big Improvements For Open-Source Intel, Radeon Graphics Drivers

    The release of Mesa 20.1 is imminent as the latest quarterly feature update to this collection of open-source OpenGL/Vulkan drivers predominantly in use by Linux systems. Here is a look at the many exciting improvements with Mesa 20.1.

  • Hybrid cloud and multi-cloud: what is the difference?

    Hybrid cloud and multi-cloud are two exclusive terms that are often confused. While the hybrid cloud represents a model for extending private cloud infrastructure with one of the existing public clouds, a multi-cloud refers to an environment where multiple clouds are used at the same time, regardless of their type. Thus, while the hybrid cloud represents a very specific use case, multi-cloud is a more generic term and usually better reflects reality.

    Although both architectures are relatively simple to implement from the infrastructure point of view, the more important question is about workloads orchestration in such environments. In the following blog, I describe the differences between hybrid clouds and the multi-cloud and discuss the advantages of orchestrating workloads in a multi-cloud environment with Juju.

    [...]

    In turn, multi-cloud simply refers to using multiple clouds at the same time, regardless of their type. There is no dedicated infrastructure that facilitates it. There is no dedicated link, single IdM system, unified LMA stack or an integrated network. Just instead of a single cloud, an organisation uses at least two clouds at the same time.

    The goal behind the multi-cloud approach is to reduce the risk of relying on a single cloud service provider. Workloads can be distributed across multiple clouds which improves independence and helps to avoid ‘vendor lock-in’. Furthermore, as the multi-cloud is usually a geographically-distributed environment, this helps to improve high availability of applications and their resiliency against failures. Finally, the multi-cloud approach combines the best advantages of various cloud platforms. For example, running databases on virtual machines (VMs) while hosting frontend applications inside of containers. Thus, workload orchestration remains the most prominent challenge in this case.

  • Kubernetes for Data Science: meet Kubeflow

    Data science has exploded as a practice in the past decade and has become an undisputed driver of innovation.

    The forcing factors behind the rising interest in Machine Learning, a not so new concept, have consolidated and created an unparalleled capacity for Deep Learning, a subset of Artificial Neural Networks with many hidden layers, to thrive in the years to come.

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.
