  • Colin Walters: “Immutable” → reprovisionable, anti-hysteresis

    Why not "immutable"/"read-only"?

    Because it’s very misleading. These system as a whole is not immutable, or read-only, or stateless – there are writable, persistent data areas. And more importantly, those writable data areas allow persistently storing privileged code.

    Usually instead of talking about an "immutable" system that allows in place updates, it’d be more useful and accurate to say "image based".

    And this gets into another huge difference between traditional package managers and image based systems: The amount of "internal state".

    The way most package managers work is when you type $pkgmgr install foo, the fact that you want foo installed is recorded by adding it to the database. But the package manager database also includes a whole set of "base packages" that (usually) you didn’t choose. Those "base packages" might come from a base container when you podman/docker pull, for cloud images the default image, and physical systems they often come from a distribution-specific default list embedded/downloaded from the ISO or equivalent.

    A problem with this model then is "drift" – by default if the distribution decides to add a package to the base set by default, you (usually) don’t get it by default when applying in place updates since most package managers just update the set of packages you have. One solution to this is metapackages, but if not everything in the base is covered you still have drift that can be hard to notice over time.

  • Apoorv Sachan: My First GUADEC

    Finally, here it is! My "My First GUADEC" post. It’s been three months since I have been working on my GSoC project, and as the project itself and GSoC approach their final days, I would like to talk about my GUADEC experience. Ever since the GSoC results were announced, I had been aware of the fact that GSoC students, not only get to attend but also get an opportunity to present their work at the annual GNOME Conference called GUADEC, which brings together users and enthusiasts from all over the world. Words are not enough to express the kind of excitement I’ve had for attending this.


  • Virtual Conferences

    Probably the most obvious part of the evolution of virtual events is the clearly visible (and audible) quality improvements. A very welcome change especially for the larger events where you spent all day listening to people, and that can be quite exhausting if we don’t properly understand what’s being said and have to manually adjust audio levels for each speaker.

    The increased quality requirements also impacted my own setup, moving from built-in webcam and simple headset to full HD external camera, lapel microphone, proper lighting and OBS for scene composition, cleaning the audio feed and recording, with a virtual V4L webcam and a virtual PulseAudio microphone feeding this into the corresponding conference software. A bit too complex and fragile for my taste, but producing a much better result.


    The biggest gain provided by virtual events is the far far lower threshold for attending. No travel, much lower cost (if any), often not even a registration, you can just drop in and see if the event is interesting to you and you feel comfortable there before getting more involved.

    I noticed this was even the case for myself, and I’m not exactly facing a particular high threshold there, having attended many events during the past 15+ years, usually belonging to the majority demographic, having a passport that lets me travel easily to most parts of the world and having access to multiple travel expense funding sources. So I can only imagine this to be making a much larger difference for people not checking all those boxes.

    Since June I have tried to attend any conference or meetup I became aware of that is vaguely related to KDE Itinerary, not all of which I would have attended physically probably. Every single one however turned out to have been very much worth it, yielding concrete results for KDE Itinerary. If you follow the regular development summaries you will already have spotted a few of those, and there’s more to come.

  • Multiple Datasets to GCompris Memory Game Activities

    In the past blogs, I wrote about the status of my GSoC work. Continuing the same in this blog I would like to update about one of my major project milestones I have achieved.

  • GSoC’20 Progress: Onward with the Third Month

    It’s been a while since my last update. In this post, I will describe the work I have done up until now in Phase Three of the coding period.

    This phase, I worked on making the subtitles displayed on the timeline editable.

    Since the text and end positions are both values for the Subtitle model item of a subtitle at a particular start position, I wrote a function that deals with customizing the text as well as the end positions.

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.
