Linux on Mars: 17 flights later

Filed under

Last year was a big year for Linux, as the operating system (OS) played a critical role in a major achievement: the first-ever powered flight on another planet. On 19 April last year, the Ingenuity drone – or “Mars Helicopter”, as NASA calls it – took to the skies of Mars. Under the hood, the on-board computer was running Linux.

Last year, we spoke with Tim Canham, the software and operations lead on the project, who shared with us details of how the helicopter works. Now, a staggering 17 successful flights later, we thought it was time to check in on the helicopter’s progress.

Gnuastro 0.17 released

Filed under
Dear all,

I am happy to announce the 17th official release of GNU Astronomy
Utilities (Gnuastro).

As you see in [1] below, many useful new features have been added,
and many bugs have been found and fixed. Thanks to 8 people who
directly committed into Gnuastro's source (4 women and 4 men), and
20 people providing ideas that have been impleted (see below for
the names). This is a new record in Gnuastro! Thanks for helping
make Gnuastro better with your great contributions and feedback :-).

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 (*.sig)
see [3]:     (3.8MB)  (833B)     (6.0MB)  (833B)

Here are the SHA1 and SHA256 checksums (other ways to check if the
tarball you download is what we distributed). Just note that the
SHA256 checksum is base64 encoded, instead of the hexadecimal encoding
that most checksum tools default to.

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 6.8
  Autoconf 2.71
  Automake 1.16.4
  Help2man 1.49.1
  ImageMagick 7.1.0-27
  Gnulib v0.1-5187-g2ca890b564
  Autoconf archives v2022.02.11-1-g203f15b

The dependencies to build Gnuastro from this tarball on your system
are described here:

Best wishes,

Could Unix Happen Today? Brian Kernighan Looks Back ... and Forward

Filed under

As beloved Unix pioneer Brian Kernighan approaches his 80th birthday, he made a special appearance at this year’s Linux Conference Australia. At the traditional January event — held virtually for the second year in a row — Kernighan reminisced on the 1970s and “The early days of Unix at Bell Labs,” always careful to acknowledge the contributions of others, and of those developers who’d preceded him.

Kernighan also used the occasion to reflect on the lessons to be learned from the history of the Unix operating system, from the C programming language, and even from Microsoft’s foray into Unix — ultimately asking the poignant question of whether a Unix-like phenomenon could ever happen again.

And finally, Kernighan also looked to the future, and expressed a sincere hope that the talk might “perhaps teach us something about how software development can be done effectively, and perhaps how to manage people and processes to make them as productive as possible.”

Canonical, NASA, and Award-Winning Artist Team Up for Space Art Project

Filed under

Ubuntu (and Linux in general) is already used in a variety of practical space applications, from powering smart robots to helping rovers rove. But one area it’s yet to boldly go —sorry, couldn’t resist— is into the realm of cosmic creativity.

Until now, that is.

Boundary-pushing artist Cecilie Waagner Falkenstrøm and the team at ARTificial Mind want to “advance the next epoch of digital art”. Their artistic tools of choice? Ubuntu Core, artificial intelligence, and, the universe.

SciDAVis is an open-source application for scientific data analysis and data visualization

Filed under

SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility.

Alternative to:

SciDAVis is similar in its field of application to proprietary Windows applications like Origin and SigmaPlot as well as free applications like QtiPlot, Labplot, and Gnuplot.

What sets SciDAVis apart from the above is its emphasis on providing a friendly and open environment (in the software as well as the project) for new and experienced users alike.

Fun with Telescopes

Filed under

Recently I purchased a small telescope to look at solar spots. When choosing a mount, I checked whether it can be controlled with OSS.

In this context INDI is mentioned everywhere and my desired mount was supported. indi and kstars are already part of Debian, so “apt install”, selecting my mount, …. oh, wait, the menu shows it, but I can not select it.

Ok, that was the time when I learned about the difference of indi and indi-3rdparty. The indi package just contains a few drivers and others are available from a different repository. This split has been done either due to different release cycles of the driver, a different OSS license of it, or just due to binary blobs without source being part of some drivers.

Fine, there are already packages of the 3rdparty-repository available from an Ubuntu PPA, so it should be no problem to add them do Debian as well.

  • 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.
