  • Mac’s share falls to five-year low

  • A 2016 retrospective

    In 2012, your editor predicted that LibreOffice would leave OpenOffice (which had been recently dumped into the Apache Software Foundation) in the dust. That prediction was accounted as a failure at the end of the year. Four years later, though, it has become clear that that is exactly what has happened. Your editor happily takes credit for having been a bit ahead of his time, while pointing to something shiny to distract you all from the fact that he didn't see the issue coming to a head in 2016.

    The Intel developer working on UMIP (User-Mode Instruction Prevention) support for the Linux kernel has been collaborating with Wine developers about this security-minded feature to be introduced with future Intel CPUs.

  • GNOME, Wayland, and environment variables

    Your editor, who is normally not overly worried about operating-system upgrades, approached the Fedora 25 transition on his laptop with a fair amount of trepidation. This is the release that switches to using Wayland by default, pushing aside the X.org server we have been using for decades. Such a transition is bound to bring surprises, but the biggest surprise this time around was just how little breakage there is. There is one exception, though, that brings back some old questions about how GNOME is developed.

    The problematic change is simple enough to understand. While X sessions are started by way of a login shell in Fedora (even though the user never sees that shell directly), Wayland sessions do not involve a shell at all. As a result, the user's .bash_profile and .bashrc files (or whichever initialization files their shell uses) are not read. The place where this omission is most readily noticed is in the definition of environment variables. Many applications will change their behavior based on configuration stored in the environment; all of that configuration vanishes under Wayland. It also seems that some users (xterm holdouts, for example) still run applications that use the old X resources configuration mechanism. Resources are normally set by running xrdb at login time; once again, that doesn't happen if no login shell is run.

  • 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.
