GNOME, Arch and FreeBSD

  • Phaedrus Leeds: Cleaning Up Unused Flatpak Runtimes

    Despite having been a contributor to the GNOME project for almost 5 years now (first at Red Hat and now at Endless), I’ve never found the time to blog about my work. Fortunately in many cases collaborators have made posts or the work was otherwise announced. Now that Endless is a non-profit foundation and we are working hard at advocating for our solutions to technology access barriers in upstream projects, I think it’s an especially good time to make my first blog post announcing a recent feature in Flatpak, which I worked on with a lot of help from Alex Larsson. On many low-end computers, persistent storage space is quite limited. Some Endless hardware for example has only 32 GB. And we want to fill much of it with useful content in the form of Flatpak apps so that the computers are useful even offline. So often in the past we have shipped computers that are already quite full before the user stores any files. Ideally we want that limited space to be used as efficiently as possible, and Flatpak and OSTree already have some neat mechanisms to that end, such as de-duplicating any identical files across all apps and their runtimes (and, in the case of Endless OS, including the OS files as well).

  • Outreachy Progress Report

    I’m halfway gone into my Outreachy internship at the GNOME Foundation. Time flies so fast right? I’m a little emotional cuz I don’t want this fun adventure to end soo soon. Just roughly five weeks to go!! Oh well, let’s find out what I’ve been able to achieve over the past eight weeks and what my next steps are… My internship project is to complete the integration between the GNOME Translation Editor (previously known as Gtranslator) and Damned Lies(DL). This integration involves enabling users to reserve a file for translation directly from the Translation Editor and permitting them to upload po files to DL.

  • Kubernetes on Hetzner in 2021

    Hello and welcome to my little Kubernetes on Hetzner tutorial for the first half of 2021. This tutorial will help you bootstrapping a Kubernetes Cluster on Hetzner with KubeOne. I am writing this small tutorial, because I had some trouble to bootstrap a cluster on Hetzner with KubeOne. But first of all let us dive into the question why we even need KubeOne and how does KubeOne helps. KubeOne is a small wrapper around kubeadm. Kubeadm is the official tool for installing Kubernetes on VMs or bare-metal nodes, but it has one major disadvantage: It is very toilsome. KubeOne tries to solve this with providing you a wrapper around Kubeadm and various other provisioning tools like Terraform. Terraform lets you manage your infrastructure as code. The advantage is that you can easily destroy, deploy or enhance your infrastructure via a few config file changes. You may ask yourself why you even need this tutorial. There is already at least one tutorial that guides you through the process of setting up a Kubernetes cluster on Hetzner. This is correct, but I felt it is unnecessary complicated, takes too much manual steps and is not really automatable (although there are solutions like kubespray that intend to solve this).

  • FreeBSD Desktop – Part 22 – Configuration – Aero Snap Extended

    I like to post new articles and solutions when I think they are ready. Production tested and stable. Well thought and tested … or at least trying to make things as good as possible in the available time window. Perfectionism definitely does not help making often articles on the blog.

    Today’s solution is not perfect but I will ‘ship it’ anyway because good and done is better then perfect. I wanted to rework it so many times that I stopped counting … and I really would like to continue the series – thus I have made a conscious decision to finally release it and hope that maybe someone else will have better ideas to make it better. I really wanted to provide pixel perfect solution with as much screen space used as possible but to deliver it as it is I tested it only on the resolution I use the most – the FullHD one with 1920×1080 pixels.

    You may want to check other articles in the FreeBSD Desktop series on the FreeBSD Desktop – Global Page where you will find links to all episodes of the series along with table of contents for each episode’s contents.

Oracle, Red Hat, and CloudLinux

  • Cloud Native Patterns: a free ebook for developers

    Building cloud native applications is a challenging undertaking, especially considering the rapid evolution of cloud native computing. But it’s also very liberating and rewarding. You can develop new patterns and practices where the limitations of hardware dependent models, geography, and size no longer exist. This approach to technology can make cloud application developers more agile and efficient, even as it reduces deployment costs and increases independence from cloud service providers. Oracle is one of the few cloud vendors to also have a long history of providing enterprise software. Wearing both software developer and cloud service provider hats, we understand the complexity of transforming on-premises applications into cloud native applications. Removing that complexity for customers is a guiding tenet at Oracle.

  • Red Hat extends certification expiration dates and expands remote offerings

    In 2020, remote exams became the standard experience for certificate-hopefuls across many fields. Red Hat worked quickly to release four of our most in-demand exams in this format. We have seen remote exams grow rapidly in popularity with our candidates. As we roll into 2021, our list has expanded with even more offerings. Now, you can take advantage of more remote exams to validate your skills in Red Hat’s most in-demand technologies, including OpenShift, Ansible, Containers and Kubernetes, and more.

  • Gnuastro 0.14 released
    Dear all,
    
    I am happy to announce the availability of Gnuastro 0.14. For the full
    list of added and changed/improved features, see the excerpt of the
    NEWS file for this release in [1] below.
    
    Gnuastro is an official GNU package, consisting of various
    command-line programs and library functions for the manipulation and
    analysis of (astronomical) data. All the programs share the same basic
    command-line user interface (modeled on GNU Coreutils). For the full
    list of Gnuastro's library, programs, and a comprehensive general
    tutorial (recommended place to start using Gnuastro), please see the
    links below respectively:
    
    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html
    https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html
    https://www.gnu.org/s/gnuastro/manual/html_node/General-program-usage-tutorial.html
    
    The most prominent new feature may be the new Query program (called
    with 'astquery'). It allows you to directly query many large
    astronomical data centers (currently VizieR, NED, ESA and ASTRON) and
    only download your selected columns/rows. For example with the command
    below you can download the RA, Dec and Parallax of all stars in the
    Gaia eDR3 dataset (from VizieR) that overlap with your
    'image.fits'. You just have to change '--dataset' to access any of the
    +20,000 datasets within VizieR for example! You can also search in the
    dataset metadata from the command-line, and much more.
    
      astquery vizier --dataset=gaiaedr3 --overlapwith=image.fits \
               --column=RAJ2000,DEJ2000,Plx
    
    See the new "Query" section in the Gnuastro book for more:
    
    https://www.gnu.org/software/gnuastro/manual/html_node/Query.html

    release. To uncompress Lzip tarballs, see [2]. To check the validity
    of the tarballs using the GPG detached signature (*.sig) see [3]:

    I am very grateful to (in alphabetic order) Pedram Ashofteh Ardakani,
    Thérèse Godefroy, Raúl Infante-Sainz, Sachin Kumar Singh, Samane Raji
    and Zahra Sharbaf for directly contributing to the source of Gnuastro
    since the last alpha-release. It is great that in this release we have
    an equal gender balance in the contributors. I sincerely hope this can
    continue in the next release :-).
    
    I am also very grateful to (in alphabetic order) Antonio Diaz Diaz,
    Paul Eggert, Andrés García-Serra Romero, Thérèse Godefroy, Bruno
    Haible, Martin Kuemmel, Javier Licandro, Alireza Molaeinezhad, Javier
    Moldon, Sebastian Luna Valero, Samane Raji, Alberto Madrigal, Carlos
    Morales Socorro, Francois Ochsenbein, Joanna Sakowska, Zahra Sharbaf,
    Sachin Kumar Singh, Ignacio Trujillo and Xiuqin Wu for their very
    useful comments, suggestions and bug fixes that have now been
    implemented in Gnuastro since the last alpha-release.
    
    If any of Gnuastro's programs or libraries are useful in your work,
    please cite _and_ acknowledge them. For citation and acknowledgment
    guidelines, run the relevant programs with a `--cite' option (it can
    be different for different programs, so run it for all the programs
    you use). Citations _and_ acknowledgments are vital for the continued
    work on Gnuastro, so please don't forget to support us by doing so.
    
    This tarball was bootstrapped (created) with the tools below. Note
    that you don't need these to build Gnuastro from the tarball, these
    are the tools that were used to make the tarball itself. They are only
    mentioned here to be able to reproduce/recreate this tarball later.
      Texinfo 6.7
      Autoconf 2.70
      Automake 1.16.2
      Help2man 1.47.17
      ImageMagick 7.0.10-59
      Gnulib v0.1-4396-g3b732e789
      Autoconf archives v2019.01.06-98-gefa6f20
    
    The dependencies to build Gnuastro from this tarball on your system
    are described here:

  • LibreOffice Community Member Monday: Felipe Viggiano and Zhenghua Fong

    In the future, I would like to start contributing more with others teams, and with TDF in order to help increase LibreOffice’s success. In my opinion, LibreOffice needs to be better known – we have a great free office solution that attends the majority of the requirements of the general public, but, at least in Brazil, many people are not aware of this!

  • ISA2 Launches New Open Source Bug Bounties

    Awards of up to EUR 5000 are available for finding security vulnerabilities in Element, Moodle and Zimbra, open source solutions used by public services across the European Union. There is a 20% bonus for providing a code fix for the bugs they discover.

  • Amazon Creates ALv2-Licensed Fork of Elasticsearch

    Amazon states that their forks of Elasticsearch and Kibana will be based on the latest ALv2-licensed codebases, version 7.10. “We will publish new GitHub repositories in the next few weeks. In time, both will be included in the existing Open Distro distributions, replacing the ALv2 builds provided by Elastic. We’re in this for the long haul, and will work in a way that fosters healthy and sustainable open source practices—including implementing shared project governance with a community of contributors,” the announcement says.

  • Elasticsearch and Kibana are now business risks

    In a play to convert users of their open source projects into paying customers, today Elastic announced that they are changing the license of both Elasticsearch and Kibana from the open source Apache v2 license to Server Side Public License (SSPL). If your organisation uses the open source versions of either Elasticsearch or Kibana in its products or projects, it is now at risk of being forced to release its intellectual property under terms dictated by another.

  • Wikipedia Turns Twenty

    If there is a modern equivalent to Encyclopédie for cultural impact, scale of content, and controversy, it’s surely Wikipedia, the free open-source online encyclopedia run by the not-for-profit Wikimedia Foundation. Started by entrepreneurs Jimmy Wales and Larry Sanger on January 15th, 2001, it has since grown to become one of the world’s top 15 websites with a vast database of 55 million articles in 317 languages, as well as a family of related projects covering everything from travel guides to recipes. Beloved of geeks, friend to lazy students and journalists alike, and bane to procrastinators, it celebrates its 20th birthday this month.

    It’s hard to overstate just how much information is on Wikipedia. You can instantly find the average July temperature in Lisbon, the difference between an ale and a lager, the historical background to the Fifth Amendment of the United States Constitution, or the full list of 10 ways a batsman can be out in cricket. The illustrated article on aguaxima includes far more information than Diderot’s effort, and readers can find a far more accurate article on religion in Sweden. These articles all link to their sources, so a reader can do their own fact-checking.

    There is one more crucial difference between Encyclopédie and Wikipedia, though. Encyclopédie’s subscribers needed to pay 280 livres for it, far beyond the wages of an ordinary person. But anyone who can afford a device with an Internet connection can access Wikipedia wherever they go. This accessibility was game-changing.
