  • 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:

    release. To uncompress Lzip tarballs, see [2]. To check the validity

    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

    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.

  • 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!

  • 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.

  • 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.
