  • State persistence for apps and sessions: Endless Orange Week | Philip Withnall

    Those two bullet points hide a lot of complexity, and it’s not surprising that I didn’t get particularly far in this project! It requires coordinated changes in a lot of components: GLib, GTK, gnome-session and applications themselves.

    A lot of these changes have been prototyped or worked on before, by various people, but nothing has yet come together. In fact, gnome-session used to fully support restoring apps to a certain degree — before it was ported away from XSMP, it used to support saving the set of apps when closing a session, and re-starting those apps when starting the session again. It did not support restoring the state of each app, though, just the fact that it was running.

  • GstVA in GStreamer 1.20 – Herostratus’ legacy

    It was a year and half ago when I announced a new VA-API H.264 decoder element in gst-plugins-bad. And it was bundled in GStreamer release 1.18 a couple months later. Since then, we have been working adding more decoders and filters, fixing bugs, and enhancing its design. I wanted to publish this blog post as soon as release 1.20 was announced, but, since the developing window is closed, which means no more new features will be included, I’ll publish it now, to create buzz around the next GStreamer release.

  • Carlos Garnacho: An Eventful Instant

    Traditionally, GNOME Shell has been compressing pointer motion events so its handling is synchronized to the monitor refresh rate, this means applications would typically see approximately 60 events per second (or 144 if you follow the trends).

    This trait inherited from the early days of Clutter was not just a shortcut, handling motion events implies looking up the actor that is beneath the pointer (mainly so we know which actor to send the event to) and that was an expensive enough operation that it made sense to do with the lowest frequency possible. If you are a recurrent reader of this blog you might remember how this area got great improvements in the past.

    But that alone is not enough, motion events can also end up handled in JS land, and it is in the best interest of GNOME Shell (and people complaining about frame loss) that we don’t need to jump into the JavaScript machinery too often in the course of a frame. This again makes sense to keep to a minimum.

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.
