  • Hybrid work model: 4 best practices for fairness | The Enterprisers Project

    As vaccinations bring us closer than ever to a post-COVID world, many business leaders are contemplating the future of their offices – when, where, and how to fill the workspaces that have sat dormant for the last 13 months.

    But according to Pew Research, more than half of workers whose jobs can be done from home want to continue working remotely after the pandemic ends. And employers seem to be embracing a hybrid work model for the post-COVID world, with many planning for local employees to come into the office only a few days per week and allowing some individuals to stay entirely remote.

  • Fedora Community Blog: Heroes of Fedora (HoF) – F34 Beta

    Hello everyone, welcome to the Fedora Linux 34 Beta installation of Heroes of Fedora! In this post, we’ll look at the stats concerning the testing of Fedora Linux 34 Beta. The purpose of Heroes of Fedora is to provide a summation of testing activity on each milestone release of Fedora. Without community support, Fedora would not exist, so thank you to all who contributed to this release! Without further ado, let’s get started!

  • CentOS Looks To Deal With Deprecated Device Support, Out-Of-Tree Kernel Modules - Phoronix

    Being proposed within the CentOS project is a new special interest group for providing kernel modules not otherwise available within CentOS Stream. This would also include changes around where CentOS / Red Hat disable some kernel modules or artificially limit the scope of supported hardware.

    The CentOS "kmods" SIG is being considered for dealing with kernel modules not available in CentOS Stream but could be beneficial to it. The proposed SIG would focus on restoring support for deprecated devices where it just means build time changes or other kernel alterations compared to the Stream / RHEL kernel configuration, offering in-tree kernel modules not enabled for CentOS, and out-of-tree kernel modules too.

  • Create and manage Red Hat Data Grid services in the hybrid cloud | Red Hat Developer

    In a recent article, we described how we used Red Hat Data Grid, built from the Infinispan community project, to deliver a global leaderboard that tracked real-time scores for an online game.

    In this article, we’re back to demonstrate how we used the Red Hat Data Grid Operator on Red Hat OpenShift to create and manage services running on AWS (Amazon Web Services), GCP (Google Cloud Platform), and Microsoft Azure. In this case, we used the Data Grid Operator to create a global Data Grid cluster across multiple cloud platforms that appeared as a single Data Grid service to external consumers.

    Note: The global leaderboard was featured during Burr Sutter's Red Hat Summit keynote in April 2021. Get a program schedule for the second half of this year's virtual summit, coming June 15 to 16, 2021.

  • Achieving polyglot persistence with application stream databases in Red Hat Enterprise Linux 8.4

    Today’s applications need a modern data infrastructure—one that can provide developer agility, yet offer a solid foundation. A database, backed by a solid operating system, is at the heart of building such foundations. Across both commercial and open source database offerings, the choices are virtually unlimited. In recent years, the popularity of open source databases has drastically increased, and this gap is quickly narrowing (see Figure 1).

  • Firefox 89 on POWER

    Firefox 89 was released last week with much fanfare over its new interface, though being the curmudgeon I am I'm less enamoured of it. I like the improvements to menus and doorhangers but I'm a big user of compact tabs, which were deprecated, and even with compact mode surreptitously enabled the tab bar is still about a third or so bigger than Firefox 88 (see screenshot). There do seem to be some other performance improvements, though, plus the usual more lower-level changes and WebRender is now on by default for all Linux configurations, including for you fools out there trying to run Nvidia GPUs.

    The chief problem is that Fx89 may not compile correctly with certain versions of gcc 11 (see bugs 1710235 and 1713968). For Fedora users if you aren't on 11.1.1-3 (the current version as of this writing) you won't be able to compile the browser at all, and you may not be able to compile it fully even then without putting a # pragma GCC diagnostic ignored "-Wnonnull" at the top of js/src/builtin/streams/PipeToState.cpp (I still can't; see bug 1713968). gcc 10 is unaffected. I used the same .mozconfigs and PGO-LTO optimization patches as we used for Firefox 88. With those changes the browser runs well.

  • Introduction to RHEL System Roles

    In today’s IT environments, organizations are having to manage an ever-growing quantity of systems. These systems need to scale within and outside of the traditional datacenter. This requires organizations to depend ever more on automation to perform tasks. Deploying and managing an operating system like Red Hat Enterprise Linux (RHEL) can be time-consuming without automation, with administration and maintenance tasks taking significantly longer to complete.

    RHEL System Roles are a collection of Ansible roles and modules that can help automate the management and configuration of RHEL Systems. RHEL System Roles can help provide consistent and repeatable configuration, reduce technical burdens, and streamline administration. In this post, we’ll show you how to use the know-how of Red Hat with RHEL System Roles, so you can spend more time doing work that's more valuable to the business and less time reinventing the wheel.

  • 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.
