  • Gnuastro 0.12 released
    Hello,
    
    I am happy to announce the 12th stable version of GNU Astronomy
    Utilities (Gnuastro):
    
    Gnuastro is an official GNU package 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
    
    Many new features have been added, and many bugs have been fixed in
    this release. For the full list, please see [1] below (part of the
    NEWS file within the tarball). Here are the highlights (done by the
    new contributors to Gnuastro's source): The Crop program's `--polygon'
    option now works on concave polygons (when an internal angle is larger
    than 180 degrees). This is very useful for cropping out some deep
    fields that have zig-zag-like edges. It can also deal with
    self-intersecting polygons. Also, the Table program can now select
    rows based on their position within a polygon, it can concatenate
    columns of multiple tables (with same number of rows), and it can
    convert RA (in HH:MM:SS) and Dec (in DD:MM:SS) to degrees and
    vice-versa: with its four new column-arithmetic operators.
    
    Here is the compressed source and the GPG detached signature for this
    release. To uncompress Lzip tarballs, see [2]. To check the validity
    of the tarballs using the GPG detached signature see [3]:

    Since Gnuastro 0.11, Madhav Bansal, Sachin Kumar Singh and Kartik Ohri
    have contributed to the source of Gnuastro and Raúl Infante-Sainz
    Raphael Morales, Alejandro Serrano Borlaff, Zahra Sharbaf, Joseph
    Putko provided very useful comments, suggestions and bug fixes that
    have been implemented. Thanks a lot for helping improve Gnuastro :-).
    
    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 2.69
      Automake 1.16.2
      Help2man 1.47.15
      ImageMagick 7.0.10-13
      Gnulib v0.1-3428-gb3c04ecec
      Autoconf archives v2019.01.06-97-gfd1d25c
    
    The dependencies to build Gnuastro from this tarball on your system
    are described here:

  • 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.
