  • How BuildStream uses OSTree

    I’ve been asked a few times about the relationship between BuildStream and OSTree. The answer is a bit complicated so I decided to answer the question here.

    OSTree is a content-addressed content store, inspired in many ways by Git but optimized for storing trees of binary files rather than trees of text files.

    BuildStream is an integration tool which deals with trees of binary files, and at present it uses OSTree to help with storing, identifying and transferring these trees of binary files.

    I’m deliberately using the abstract term “trees of binary files” here because neither BuildStream or OSTree limit themselves to a particular use case. BuildStream itself uses the term “artifact” to describe the output of a build job and in practice this could be the set of development headers and documentation for library, a package file such as a .deb or .rpm, a filesystem for a whole operating system, a bootable VM disk image, or whatever else.

  • tmux – A Powerful Terminal Multiplexer For Heavy Command-Line Linux User

    tmux stands for terminal multiplexer, it allows users to create/enable multiple terminals (vertical & horizontal) in single window, this can be accessed and controlled easily from single window when you are working with different issues.

    It uses a client-server model, which allows you to share sessions between users, also you can attach terminals to a tmux session back. We can easily move or rearrange the virtual console as per the need. Terminal sessions can freely rebound from one virtual console to another.

  • Graphics and music tools for game development

    In early October, our club, Geeks and Gadgets from Marshall University, participated in the inaugural Open Jam, a game jam that celebrated the best of open source tools. Game jams are events where participants work as teams to develop computer games for fun. Jams tend to be very short—only three days long—and very exhausting. Opensource.com announced Open Jam in late August, and more than three dozen games were entered into the competition.

    Our club likes to create and use open source software in our projects, so Open Jam was naturally the jam we wanted to participate in. Our submission was an experimental game called Mark My Words. We used a variety of free and open source (FOSS) tools to develop it; in this article we'll discuss some of the tools we used and potential stumbling blocks to be aware of.

  • GNOME Tweaks 3.28 Progress Report 1

    A few days ago, I released GNOME Tweaks 3.27.4, a development snapshot on the way to the next stable version 3.28 which will be released alongside GNOME 3.28 in March. Here are some highlights of what’s changed since 3.26.

  • Chromium 64 – and 32bit pain

    The new release of the Chromium sources gives us version 64 of Google’s browser. I have created Slackware packages for you, but that was not entirely trivial.

    The Chromium compilation on my 32bit Slackware OS kept failing on the embedded ffmpeg. I am afraid the fact that some of the bigger distros are dropping 32bit variants starts showing and things are coming apart at the seams.

    When you are a developer and there’s no 32bit release of your favorite OS, this makes it quite difficult to test the validity of code paths when you only compile and test your code on a 64bit platform. This is what’s happening with Google’s Chromium code and it will probably only get worse.

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.
